Authors: Lazovic Ranko , Radunovic Miodrag , Dobricanin Vladimir
Published: January 2012

Meckel?s diverticulum represents one of the most common congenital anomalies
of the gastrointestinal system. It appears in 1-3% of the general population.
In this case study we presented 72 year old male patient who was admitted in
the Center for abdominal surgery, Clinical Center of Montenegro. The symptoms
were diffuse, severe abdominal pain, nausea and vomiting with intestinal
obstruction. After the preoperative diagnostic procedures we performed
resection of the terminal ileum and T-T anastomosis. Whenever the patient has
the clinical findings of acute abdomen and no matter if patient is in
elderly, we should think on complications of the Meckel?s diverticulum.

Authors: Mrdja Jelena , Crnobarac Jovan , Dusanic Nenad , Jocic Sinisa , Miklic Vladimir
Published: January 2012

Using the standard method, we studied the germination energy of seed of seven
different sunflower genotypes (five hybrids and two cytoplasmically male
sterile female lines) developed at the Institute of Field and Vegetable Crops
in Novi Sad. The seed was treated with the fungicides benomil, metalaxyl and
fludioxonil and the insecticides thiamethoxam and imidacloprid and kept for a
year in a storage facility. Analysis of variance showed that there were
highly significant differences among the genotypes, chemical treatments, and
storage periods. Highly significant differences were also recorded for all
the interactions among the factors studied. On average, the highest
germination energy was found in the hybrid H2 (93.45%), whose values of this
parameter were highly significantly higher than those of the rest of the
genotypes, except for the hybrid H1. Also, each of the hybrids had highly
significantly higher germination energy than either of the two lines, and the
differences among the hybrids themselves were highly significant. Looking at
the chemical treatments, the control had the highest germination energy by a
highly significant margin (80.39%). The largest difference was observed in
relation to the treatments with insecticides (5.48 and 9.56%). These
treatments had highly significantly lower values of germination energy than
those involving fungicides. Germination energy increased in the first nine
months of storage, peaking at 81.29%. After that, there was a sharp drop to
68.94% after 12 months of storing. Differences among the different storage
periods were all highly significant except for that between six and nine
months of storage, which was not statistically significant.
Influence of agroclimatic conditions on content of main cannabinoids in industrial hemp (Cannabis sativa L.)
Authors: Sikora Vladimir , Berenji Janos , Latkovic Dragana
Published: January 2012

In a six-year field experiment eight industrial hemp varieties were examined
for ?9-tetrahydrocannabinol (THC) and cannabidiol (CBD) contents. The study
analyzed the influence of growing degree days (GDD), soil temperature at 5
cm, air humidity, and growing season precipitation on the levels of the main
cannabinoids in this crop. Agroclimatic conditions do not influence THC and
CBD contents in industrial hemp in the same way. THC synthesis and
accumulation are under the significant positive influence of GDD and air
humidity and under the negative influence of precipitation, while soil
temperature at 5 cm has no significant effect on it. Soil temperature at 5 cm
has a significant positive effect on the CBD content, as do GDD.
Precipitation has a negative influence on the CBD content of industrial hemp,
while air humidity has no influence on it.
Clone selection of autochtones and introduced varieties in the old grapevine planted areas of south eastern and eastern Serbia and preliminary check of their health status
Authors: Sivcev Branislava , Rankovic-Vasic Zorica , Radovanovic Dragica
Published: January 2012

Clone and sanitary selection of the grapevine has a fundamental importance in
improving the quality and the quantity of the grape production in Serbia. In
order to preserve the varieties of the old vineyards, the clone and sanitary
selection has begun in 2006 in the South Eastern Serbia vineyard areas, 1048
grapevine plants have been examined in three distant vineyards and 60
grapevine plants have been separated that deserved attention based on their
production characteristics. The selected plants have been tested
serologically, with the ELISA method, to the presence of 4 grapevine viruses:
Grapevine leaf roll-associated virus 1, Grapevine leaf roll-associated virus
2 and Grapevine leaf roll-associated virus 3 (GLRaV- 1, GLRaV-2 and GLRaV-3),
and grapevine fun leaf virus- GFLV. The infection level of the selected
plants was between 10.5% (vineyard III) and 22.2% (vineyard II). We
eliminated the infected plants among the selected ones and analyzed only the
healthy ones in the 2008. Various potential variety clones have been selected
for Prokupac, Pamid, Dimyat, Sauvignon blanc, Rosaki, Chasselas, Semillon,
Detier de Bayreuth and Riesling. In 2008 we have repeated the same procedure
we did in 2006 but in a different region - the Eastern Serbia area on the
autochthonous variety of Muscat des roses noir on 400 grapevine plants 40
potential clones have been selected. The goal of this paper was check out the
health status to preserve the autochthonous and introduced varieties of the
eastern and south eastern region and to renew the vineyards it?s grown in. It
was necessary to go on following the selected candidate - clones for other
viruses based on EPPO PM 4/1-26 certification scheme in order to identify the
virus-free clones to multiply, conserve and maintain in the collection
growing areas.

Published: January 2012

Willows being multipurpose species are well recognized in short
rotation forestry world over. 200 clones of different species and
hybrids were procured from twenty countries over the period of three years.
These were subjected for nursery screening and further 18 promising clones
were planted in March, 2006 at university main campus Nauni, Solan, Himachal
Pradesh. The five years growth performance was evaluated and clone J-799 has
given maximum plant height (19.33 m) which is at par with the clone
NZ-1140 (16.33 m) followed by SI-63-007 (14.30 m). As regards with
diameter at breast height and volume index, clone J-799 registered first
rank followed by NZ-1140 and 131/25 recording 16.50 cm and 0.554 m3, 15.30
cm and 0.386 m3 ;15.30cm and 0.368m3, respectively. Bole straightness was
recorded maximum in clone J-795 that is at par with clones J-194, PN-721 and
131/25 followed by clones J-799, SI-63-007, NZ-1140 and SI-64-017.
Heritability in broad sense for bole straightness (46.36%) and genetic gain
of the volume index (67.95%) was found highest. Genotypic,
phenotypic and environment coefficients of variations were recorded maximum
(0.995) for volume index character. Genetic correlation coefficient
was highest (0.921) between plant height and volume, while
phenotypic correlation coefficient was highest between diameter at
breast height and volume index. On the basis of five year growth
performance, five clones namely J- 799, NZ-1140, 131/25, SI-63-007 and
PN-731 are found suitable for lower and mid-hills of Himachal Pradesh.
HLA II class antigens and susceptibility to coeliac disease
Authors: Vojvodic Svetlana , Ademovic-Sazdanic Dusica
Published: January 2012

Coeliac disease (CD) is a systemic autoimmune, complex and multifactorial
disorder, which is caused by interactions between genetic and environmental
factors. The only established genetic risk factors so far are the human
leucocyte antigens. The aim of this study was to assess the distribution of
II class human leukocyte antigens (HLA) in patients with coeliac disease and
to investigate the susceptibility to coeliac disease in family members. We
typed HLA DR and DQ antigens in 37 patients from Vojvodina with coeliac
disease, 23 first-degree relatives, and 210 controls, serologically using
standard lymphocytotoxicity technique. HLA DQ5(1), DQ6(1), DR11(5), DQ7(3),
DQ2 and DR15(2) were the most common antigens in the control group. Frequency
of HLA DQ2, DR3 and DR7 was higher in CD patients than in the control group.
The relative risks for HLA DQ2, DR3 and DR7 were 4.846, 6.986 and 2.106,
respectively, while positive association was found between HLA DQ2 and DR3
and CD. Frequency of HLA DQ2, DR3 and DR16(2) was higher in first-degree
relatives than in the control group while a positive association was found
between HLA DQ2 and DR3. A negative association was found between HLA DQ5(1)
and DQ6(1) in coeliac patients from Vojvodina and their relatives, in
addition to HLA DR11(5) in the group of relatives (RR=0.363,PF=0.232). These
findings indicate the impact of the HLA testing for CD in clinical practice
in order to rule out the possibility to CD in doubtful cases or in at-risk
subjects.
Characterization of vegetative and grain filling periods of winter wheat by stepwise regression procedure. II. Grain filling period
Authors: Przulj Novo , Momcilovic Vojislava
Published: January 2012

In wheat, rate and duration of dry matter accumulation and remobilization
depend on genotype and growing conditions. The objective of this study was to
determine the most appropriate polynomial regression of stepwise regression
procedure for describing grain filling period in three winter wheat
cultivars. The stepwise regression procedure showed that grain filling is a
complex biological process and that it is difficult to offer a simple and
appropriate polynomial equation that fits the pattern of changes in dry
matter accumulation during the grain filling period, i.e., from anthesis to
maximum grain weight, in winter wheat. If grain filling is to be represented
with a high power polynomial, quartic and quintic equations showed to be most
appropriate. In spite of certain disadvantages, a cubic equation of stepwise
regression could be used for describing the pattern of winter wheat grain
filling.

Published: January 2012

In marker assisted breeding programs, determination of genome polymorphism
and development of suitable molecular markers is of the greatest importance.
The aim of this research was development of RAPD markers, which will enable
quick and cost efficient DNA polymorphism analysis among closely related
sugar beet genotypes. The research was conducted on twelve sugar beet
genotypes from population of closely related genotypes. Reactions with eight
RAPD primers and five primer mixtures resulted in stable and reproducible
bands in all samples, with 44 polymorphic and 14 monomorphic loci, and
average of 6.13 bands per primer. In two-primer reactions nine new
polymorphic bands were detected. Polymorphism information content (PIC) for
each primer was calculated, while genetic variation was estimated by
calculation of the number of polymorphic loci and their percentage, observed
number of alleles, effective number of alleles, and Nei?s gene diversity. An
unweighted pair group arithmetic mean method (UPGMA) cluster analysis showed
that samples were divided in two groups with relatively high coefficient of
similarity. The presented results showed that RAPD markers can be suitable
for genetic diversity analysis in breeding material with high levels of
homology and homozygosity.
Interdependence of yield and yield components of confectionary sunflower hybrids
Authors: Hladni Nada , Jocic Sinisa , Miklic Vladimir , Saftic-Pankovic Dejana , Kraljevic-Balalic Marija
Published: January 2012

The two most important criteria for introducing new confectionary hybrids
into production are high seed and protein yield. That is why it is important
to find the traits that are measurable, and that at the same time show a
strong correlation with seed and protein yield, so that they can be used as a
criteria for confectionary hybrid breeding. Results achieved during 2008 at
the locations Rimski Sancevi (Region of Vojvodina) and Kula (Central Serbia)
show that the new confectionary hybrids are expressing higher seed yields in
comparison to standards (Vranac and Cepko) though with a lower seed oil
content. A very strong positive correlation was determined between seed yield
and seed protein content, kernel content and mass of 1000 seeds. A very
strong positive correlation was determined between seed protein content, seed
yield and mass of 1000 seeds, with protein yield. This indicates that seed
yield, seed protein content and mass of 1000 seeds have a high influence on
protein yield. The degree of interdependence between different traits is a
sign of direction which is supposed to facilitate better planning of
sunflower breeding program.
Recurrent headache and migraine heritability: Twin study
Authors: Knezevic-Pogancev Marija
Published: January 2012

The aim of the study was to determine recurrent headache (migraine and
non-migraine) heritability, among the twin pairs. Headache hritability was
investigated among 396 twin pairs (42.4% monozygotic and 57.6% dizygotic)
aged 3 to 21 years, on north part territory of Serbia-Vojvodina, during the
20 years period. Within the group of tested twin persons, 30.2% had recurrent
headaches, 9.2% migraine headache and 21% other recurrent non-migraine
headaches. Heritability quotient of all recurrent headaches was 0.3882. For
non- migraine headaches heritability quotient of 0.2286 confirmed that the
external factors influence is higher than heritability. Migraine headache
heritability quotient 0.8598 clearly proved the heritability of the migraine
headache. Both, correlation and determination quotient of the migraine
headache of all the twins (r12 0.7498; r21256.12%), monozygotic (r120.8458;
r1271.54%) and dizygotic (r120.6342; r21240.22%), show high degree of
migraine headache twin siblings dependence, and higher correlation and
significance of the difference with monozygotic twins.

Published: January 2012

At the time of soybean seed sowing in the field, a high soil moisture, low
soil and air temperatures, and crasts formation may occur, which can lead to
slow germination, poor seedling establishment, and in some cases to loss of
seed vigor. Due to the importance and prevalence of soybean the aim of this
study was to determine the quality and seed viability of different genotypes
produced at three locations in Vojvodina during 2009 and 2010. Eight soybean
varieties (Afrodita, Valjevka, Balkan, Novosadjanka, Ravnica, Ana,
Vojvodjanka and Venera) produced in Vrbas, Senta and Indjija during 2009 and
2010 were tested. Seed germination was determined using Standard laboratory
test, and vigor tests (cold test, and accelerated aging test). Studied
genotypes baheved differently in different years and at different localities.
Genotype Venera achieved high germination values in all applied tests in
2009, while genotype Afrodita had high values of the tested parameter when
conventional laboratory test was applied, and the lowest values were recorded
when vigor tests were applied. Values obtained in 2010 when all tests were
applied were above the prescribed minimum. Locality of Vrbas proved to be
more favorable for seed production in relation to localities of Indjija and
Senta due to better rainfall distribution.

Published: January 2012

Studies on the effects of sowing densities on maize grain yields under
irrigation were performed with the aim of creating favourable conditions for
plant growth and development, under which the genetic yield potential would
be maximally exploited. A two-factorial trial was performed in the period
2006-2009 on chernozem, according to the split- plot method with four
replicates. Four maize hybrids of different FAO maturity groups (ZP 341, ZP
434, ZP 684 and ZP 704) were observed in combination with seven sowing
densities (G1 - 40,816 plants ha-1, G2 - 50,125 plants ha-1, G3 - 59,524
plants ha-1, G4 - 69,686 plants ha-1, G5 - 79,365 plants ha-1, G6 - 86,286
plants ha-1 and G7 - 98,522 plants ha- 1). The obtained results showed
statistically very significant differences in maize grain yields between the
studied hybrids and the sowing densities. The lowest yields were recorded for
all studied hybrids at the lowest sowing density (40,816 plants ha-1). The
regression analysis indicated that, depending on a maize hybrid, the
following maximum yields could be expected: ZP 341 - 13.25 t ha-1 at a sowing
density of 81,000 plants ha-1, ZP 434 - 13.00 t ha-1 at a sowing density of
75,000 plants ha-1 , ZP 684 - 13.83 t ha-1 at a sowing density of 82,000
plants ha-1 and ZP 704 - 12,83 t ha-1 at the sowing density of 77,000 plants
ha-1. In accordance with the rational use of seeds, high yields are obtained
by sowing that provides 50,000 plants of ZP 434 ha-1, 60,000 plants of ZP 341
ha-1 and ZP 704 ha-1 and 70,000 plants of ZP 684 ha-1.
Poly(urethane-siloxane)s based on hyperbranched polyester as crosslinking agent: Synthesis and characterization
Authors: Pergal Marija , Dzunuzovic Jasna , Ostojic Sanja , Pergal Miodrag , Radulovic Aleksandra , Jovanovic Slobodan
Published: January 2012

A series of novel polyurethane crosslinked structures (PUs) was prepared from
?,?-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide)
(EO-PDMS-EO), 4,4?-methylenediphenyl diisocyanate and Boltorn? hyperbranched
polyester of the third pseudo generation. The hydroxyfunctional hyperbranched
aliphatic polyester with 26 end groups was used as crosslinking agent. In
order to improve the compatibility of all reactants during the synthesis, PU
samples were prepared by a step-growth polymerization in two stages in
solution. The soft EO-PDMS-EO segment content was varied in the range from 15
to 40 wt.%. The influence of the EO-PDMS-EO content on the swelling
behavior, crosslinking density, hardness, thermal and surface properties of
the synthesized PUs was investigated. The structure of the synthesized
polyurethanes was confirmed by the presence of specific bands in Fourier
transform infrared spectra. Swelling studies were carried out to determine
the crosslinking density and polyurethane networks with lower EOPDMS- EO
content revealed higher crosslinking density. The glass transition
temperature of the synthesized PUs, determined by differential scanning
calorimetry, slightly increased from 50 to 58?C by decreasing EO-PDMS-EO
content as a consequence of higher crosslinking density of samples. The
increase of EO-PDMS-EO content leads to the better thermal stability, as it
was confirmed by the value of the starting temperature of thermal
degradation. The surface of the polyurethane networks became more hydrophobic
with increasing EO-PDMS-EO content. The surface morphology of synthesized
polyurethanes was analyzed by scanning electron microscopy.

equivalent. The laboratory hosts a low-background gamma spectroscopy system
and cosmic-ray muon detectors. With the recently adopted digital data
acquisition system it is possible to simultaneously study independent
operations of the two detector systems, as well as processes induced by
cosmic-ray muons in germanium spectrometers. Characteristics and potentials
of the present experimental setup, together with some preliminary results
for the flux of fast neutrons and stopped muons, are reported here.
Beta-efficiency of a typical gas-flow ionization chamber using GEANT4 Monte Carlo simulations
Authors: Hussain Abid , Mirza Sikander , Mirza Nasir , Siddique Muhammad
Published: January 2012

GEANT4 based Monte Carlo simulations have been carried out for the
determination of efficiency and conversion factors of a gas-flow ionization
chamber for beta particles emitted by 86 different radioisotopes covering the
average-b energy range of 5.69 keV-2.061 MeV. Good agreements were found
between the GEANT4 predicted values and corresponding experimental data, as
well as with EGS4 based calculations. For the reported set of b-emitters, the
values of the conversion factor have been established in the range of
0.5?1013-2.5?1013 Bqcm-3/A. The computed xenon-to-air conversion factor
ratios have attained the minimum value of 0.2 in the range of 0.1-1 MeV. As
the radius and/or volume of the ion chamber increases, conversion factors
approach a flat energy response. These simulations show a small, but
significant dependence of ionization efficiency on the type of wall material.

Results of indoor radon survey in the dwellings of district Bhimber are
presented. Current study is continuation of our preceding studies aiming to
setup baseline indoor radon data for the state of Azad Jammu & Kashmir,
Pakistan. In this context, 60 representative houses were carefully selected
and CN-85 based box type radon detectors were installed in bedrooms and
living rooms of each house. The detectors were exposed to indoor radon for 90
days. After etching CN-85 detectors in 6M NaOH at 70?C for 3 hours, the
observed track densities were related to the indoor radon concentration using
calibration factor of 0.0092 tracks cm2/h per Bq/m3. The measured indoor
radon concentration ranged from 29 ? 11 to 58 ? 8 Bq/m3, 40 ? 9 to 60 ? 7
Bq/m3, and 29 ? 12 to 66 ? 7 Bq/m3 in the regions of Bhimber, Samani, and
Barnala, respectively. Excess relative risk factors were calculated using
measured indoor radon concentrations, by using the risk model reported in
the Biological Effects of Ionizing Radiation (BEIR VI, 1999) report. Excess
relative risk was calculated for age groups of 35 and 55 years. Using local
occupancy factor, average excess lung cancer risk for the population group of
35 and 55 years of age was found to be 0.42 ? 0.09 and 0.34 ? 0.08. The mean
annual effective dose for Bhimber, Samani, and Barnala regions were found to
be 1.05 ? 0.17 mSv, 1.09 ? 0.17 mSv, and 1.16 ? 0.17 mSv, respectively. These
values are within in the safe limits recommended by the international
organizations.
Effects of bedrock type on the indoor radon concentrations at the office buildings in Gyeongju, Korea
Authors: Park Hee , Jang Young , Kim Jae , Moon Hyun
Published: January 2012

This study measured the indoor radon concentrations at 23 administrative
office buildings in Gyeongju, Korea, which consists of 23 administrative
districts. Using the Korean geological information system, the type of
bedrock under the administrative office buildings was identified and
classified in 3 major types: granite, sedimentary rock, and sedimentary
rock-based fault. The changes in the indoor concentrations at the 23
administrative office buildings were analyzed according to the type of
bedrock. As a result, the radon concentration in the areas with the granite
bedrock was generally higher than that in the region of two other types of
bedrock. In addition, the radon concentration was evaluated according to
surface area and construction timing of the building. The indoor radon
concentration generally increased with decreasing surface area of the
building, particularly in granite distributed areas. For a building aged more
than 15 years, the radon concentration in the building in the granite area
was much higher. For the building aged 1 or 2 years, the radon concentration
was high regardless of the type of the bedrock due to radon emanation from
the building material, such as concrete.

The study included 75 subjects exposed to low doses of external ionizing
radiation and 25 subjects from the control group, all male. The first group
(A) consisted of 25 subjects employed in the production of technetium, with
an average job experience of 15 years. The second group (B) consisted of 25
subjects exposed to ionizing radiation from enclosed sources, working in jobs
involving the control of X-ray devices and americium smoke detectors, their
average work experience being 18.5 years. The third group (C) consisted of 25
subjects involved in the decontamination of the terrain at Borovac from
radioactive rounds with depleted uranium left over after the NATO bombing of
Serbia in 1999, their average job experience being 18.5 years. The control
group (K) consisted of 25 subjects who have not been in contact with sources
of ionizing radiation and who hold administrative positions. Frequencies of
chromosome aberrations were determined in lymphocytes of peripheral blood and
compared to the control group. The average annual absorbed dose determined by
thermoluminescent dosimeters for all three groups did not exceed 2 mSv. In
the present study, the largest number of observed changes are acentric
fragments and chromosome breaks. The highest occupational risk appears to
involve subjects working in manufacturing of the radio-isotope technetium.

Published: January 2012

Fission fragment angular anisotropies from neutron induced fission of 232Th
and 235U were analyzed within the frame work of the statistical model. The
analysis were made at neutron energies from threshold up to 50 MeV to deduce
the variance K 2 of the K-distribution of levels in the transition nucleus.
Our analysis shows, that the strength for the K-transition states comes
mainly from the higher angular momentas and is in accordance with Nilsson
model orbitals.
Simulated radiation effects in the superinsulating phase of titanium nitride films
Authors: Vujisic Milos , Matijasevic Dusan , Dolicanin Edin , Osmokrovic Predrag
Published: January 2012

This paper investigates possible effects of alpha particle and ion beam
irradiation on the properties of the superinsulating phase, recently observed
in titanium nitride films, by using numerical simulation of particle
transport. Unique physical properties of the superinsulating state are
considered by relying on a two-dimensional Josephson junction array as a
model of material structure. It is suggested that radiation-induced change of
the Josephson junction charging energy would not affect the current-voltage
characteristics of the superinsulating film significantly. However, it is
theorized that a relapse to an insulating state with thermally activated
resistance is possible, due to radiation-induced disruption of the fine-tuned
granular structure. The breaking of Cooper pairs caused by incident and
displaced ions may also destroy the conditions for a superinsulating phase to
exist. Finally, even the energy loss to phonons can influence the
superinsulating state, by increasing the effective temperature of the phonon
thermostat, thereby reestablishing means for an energy exchange that can
support Cooper pair tunneling.
Gamma-ray irradiation and post-irradiation at room and elevated temperature response of pMOS dosimeters with thick gate oxides
Authors: Pejovic Momcilo , Pejovic Svetlana , Dolicanin Edin , Lazarevic Djordje
Published: January 2012

Gamma-ray irradiation and post-irradiation response at room and elevated
temperature have been studied for radiation sensitive pMOS transistors with
gate oxide thickness of 100 and 400 nm, respectively. Their response was
followed based on the changes in the threshold voltage shift which was
estimated on the basis of transfer characteristics in saturation. The
presence of radiation-induced fixed oxide traps and switching traps - which
lead to a change in the threshold voltage - was estimated from the
sub-threshold I-V curves, using the midgap technique. It was shown that fixed
oxide traps have a dominant influence on the change in the threshold voltage
shift during gamma-ray irradiation and annealing.
The abortion culture issue in Serbia
Authors: Rasevic Mirjana , Sedlecki Katarina
Published: January 2012

The problem of a large number of abortions in our country was first pointed
out as far back as 1935 at the 17th Congress of Yugoslav Physicians. The
abortion problem in Serbia is still present today, even though modern science
has provided new methods and means which are a logical solution to the
dilemma on birth control methods from the health and social aspect. Namely,
total abortion rate in Serbia was estimated at 2.76 in the year 2007. It is
very high; double the number of the total fertility rate and among the
highest in Europe and the world. The term abortion culture was first used, as
far as we know, by Henry David in the introduction of the book From Abortion
to Contraception - A Resource to Public Policies and Reproductive Behavior in
Central and Eastern Europe from 1917 to the Present in 1999, without
specifically determining it. The aim of this paper is to identify the most
important factors of the deterministic basis of endemic induced abortions in
Serbia together with indirectly estimating their connection with the
existence, namely nonexistence, of the abortion culture in our country. In
that sense, potential factors of abortion incidence in Serbia which emerge
from the social system and those connected to the individual level have been
considered. In other words, a series of laws and other legal and political
documents have been analyzed which are significant for perceiving the
abortion matter, as well as institutional frameworks for family planning,
health services, educating the youth regarding reproductive health, including
findings of numerous researches carried out among women of various age and
doctors from 1990 till present day in Serbia. The following most significant
factors for the long duration of the abortion problem have been singled out:
insufficient knowledge of modern contraception, a belief that modern
contraceptive methods are harmful to health and a number of psychological
barriers as well as those arising from relationships with partners.
Gynecological attitudes about modern contraception and behavior do not differ
significantly from the rest of the population. Additionally, there are few
organized efforts to promote sex education, as well as limitations in the
family planning programme. Distinguished macro and micro factors of
traditional birth control in Serbia confirm the existence of the abortion
culture. The nature of these factors though, indicate to the presence of the
abortion culture in our country on the political, educational, health and
individual level. The abortion culture obstructs the adoption of a modern
concept of family planning and points out to the persistence of the abortion
problem in our country in the years to come.
Legal and medical aspects of the ethics committee’s work relating to abortion
Authors: Ponjavic Zoran , Varjacic Mirjana
Published: January 2012

This paper analyses the legal and medical aspects of the work of ethics
committees on abortion. According to the legislation of the Republic of
Serbia, these committees are competent to determine justifiable terms for
abortion after the twentieth week of the fetus. It is well known that
abortion is not only a medical but a legal, ethic, social and demographic
problem as well. A liberal solution in view of abortion in the first
trimester has been accepted in most European countries, as by the legislature
of the Republic of Serbia. Since prenatal diagnosis cannot always determine
the fetus state with certainty but at times may do so at a later stage,
abortion is then required when the child is already capable of extrauterine
life. The necessity for performing abortion in the third trimester is thus a
result of good knowledge of techno-medicine but also from the limited
information it provides. In such situations, the physician needs confirmation
and justification of his standpoint with respect to abortion through a legal
formulation which should contain "minimum moral". Society has found a way to
protect and help him through moral and ethic forms of prevention without
anybody?s emotions being affected. Ethics committees should thus help the
physician in view of determining the terms for performing late abortion,
since the rules of doctor?s ethics are not sufficient in this case. The
article especially analyses the work of the Ethics Committee of the Clinical
Center in Kragujevac in the period 2000-2010. It is stated that the largest
number of cases referred to determined diseases or fetus anomalies while only
a negligible number (11.29%) to the illness of the mother. There were no
requests for abortions due to legal reasons (pregnancies from criminal
offences). A significant number (40.28%) of requests submitted to the Ethics
Committee related to pregnancies under the 24th week of pregnancy. Since a
pregnancy of 24 weeks represents a boundary line between a miscarriage and
preterm birth, the paper proposes a shift in the boundary line of pregnancies
which must be terminated according to the Ethics committee, from 20 weeks of
gestation to 24 weeks of gestation. At the same time, the requirement for
narrowing legal conditions for abortion in later phases of pregnancies is
pointed out as well as abolition of legal indications.
Commuting in the settlement system of Serbia
Authors: Lukic Vesna
Published: January 2012

Territorial organization of settlement system is the framework for internal
migration flows. The purpose of this paper is to consider the relation
between commuting and the settlement structure. Commuting patterns and
characteristics of commuters in Serbia are relatively unknown and
insufficiently researched, and as such, can not be adequately used in
creation of development strategies and public policies which would include
commuters' issues. It has been emphasized the importance of research of
commuting ties between different settlements and also pointed out in which
way commuting flows could be researched and analyzed by using existing
sources, due to better understanding of connections between migrations and
settlements. Commuting patterns of workers in Serbia and interrelations
between the scope and the structure of commuting flows, as well as the type
and population size of settlements in Serbia have been examined. Apart from
territorial dimension of commuting phenomenon, socio-economic component of
commuting population has also been considered. The use of costumised
tabulations from 2002 Census have enabled us to examine all types of
commuting and emphasise dominant directions of commuting flows of
economically active population according to gender, level of education and
sector of economic activity, within the settlement hierarchy. Workers have
been classified into seven groups according to place of residence and place
of work. The findings reveal there is a clear connection between the
hierarchy structure and commuting patterns in Serbia. Further, we find some
evidence that only 9,5% of workers - commuters have been working in the
settlement of the same population size and type such as their residing
settlement. Commuting flows within Serbia?s settlement system point out to
certain variations when looking at individual categories of population, but
it can be concluded that there is general trend of commuting "upwards" within
the hierarchy of settlements.

Background/Aim. Obesity is the most common disease of nutrition and is the
consequence of reduced movement. Unfortunately, this problem is increasingly
present in juvenile age, so that the pediatric outpatient offices are
dominated by obese young people. The aim of this study was to evaluate and
quantify the effects of the reducing treatment for juvenile obesity conducted
by programmed physical exercise and controlled diet. Methods. We tested a
sample of 136 respondents of both sexes (76 girls and 60 boys) aged 13 ? 0.6
years. This prospective study took 3 months in 2007 using the experimental
methods of longitudinal weather precision. The data obtained after the
measurement were processed by the use of statistical programs to calculate
the basic and dispersion parameters. To determine the difference between the
initial and final measurements we applied the univariate analysis of variance
(ANOVA) and differences in the variables system in the space were determined
by multivariate analysis of variance (MANOVA). Results. The results of ANOVA
in the form of F values indicated that the differences between the initial
and final measurements in all parameters of circumference dimensionality and
subcutaneous fat tissue are significant (p = 0.00). Also, differences in
parameters of body constitution and indicators of alimentation showed a high
statistical significance (p = 0.00). The results of multivariante analysis
(MANOVA), using Wilk's Lambda test, also indicated that the differences
between initial and final measurements in the area of anthropometric measures
and indicators of alimentation and constitution, were statistically
significant (p = 0.00). Conclusion. Application of physical exercise and
controlled diet leads to a significant reduction of anthropometric parameters
and anthropological indicators of alimentation.

Authors: Ljaljevic Agima , Matijevic Snezana , Terzic Natasa , Andjelic Jasmina , Mugosa Boban
Published: January 2012

Background/Aim. Proper mouth and teeth hygiene has influence on the
prevention of a great number of diseases and very often some of them are not
related only to oral cavity. Most frequent diseases of mouth and teeth such
as caries and periodontal diseases are caused, among other factors, by poor
oral hygiene. They are also more frequent in young population. The aim of
this study was to estimate the influence of sociodemographic characteristics
and hygienic habit on oral health in children aged 11-15 years. Methods. This
crosssectional study was conducted by the dental teams in dentist surgeries
in Tivat Health Center between May and September 2009. The sample consisted
of patients 11 to 15 years of age. A questionnaire and dental examination of
mouth and teeth were used as research instruments. The examinations were
conducted in accordance with the World Health Organization methodology and
criteria. The data obtained from the interviews were correlated with those
obtained from the clinical examinations. Results. The results show that the
majority of respondents brush their teeth twice a day and visit the dentist
once in every six months. The research also shows that 57% respondents have
caries of deciduous teeth and over 63% respondents of permanent teeth.
Gingivitis was found in 14% and orthodontic anomalies in 44.7% respondents. A
half of respondents who brush their teeth rarely have problems with
gingivitis. There is a highly statistically significant difference between
the occurrence of gingivitis and the frequency of teeth brushing. Conclusion.
There is a significant difference between mouth and oral hygiene and sex as
well as other sociodemographic characteristics of respondents. The study
showed the correlation between occurrence of caries and the gingivitis and
frequency of teeth brushing and dental visits.

Background/Aim. Introducing tyrosine kinase inhibitors (TKIs) has essentially
changed curative approach, to be precise, clearly improved treatment
efficacy for chronic myeloid leukemia (CML). Thus, the place and usage of
allogeneic stem cell transplant (SCT) in CML treatment - as a former "nearly
monopolistic" therapeutic manner - is nowadays controversial. The objective
of this retrospective study was to evaluate the results obtained in the
treatment of CML patients, with a particular attempt to define parameters
critical for clinical benefit and superior overall outcome following
allogeneic SCT. Methods. A total of 32 CML patients (27 in chronic phase and
5 with advanced disease), with female/male ratio 11/21, aged from 9 to 54
(32 in average) years, underwent allogeneic SCTs (1993 to 2009). The initial
treatment for 25 patients was interferon alpha (IFN-?) with or without
ARA-C, and additional 7 patients with no response to imatinib mesylat (IM).
The time from diagnosis to SCT was approximately 12 (range 3- 37) months.
The patient were categorized according to the risk for the disease,
transplant-related mortality (TRM) scoring system, and stem cell (SC)
source. The basic conditioning regimen was a combination of busulphan and
cyclophosphamide (BuCy-2). Graft-versus-host disease (GvHD) was typically
prevented with cyclosporine-A (CsA) and methotrexate (MTX). Results.
Engraftment was observed in 26 (84.4%) patients, with polymorphonuclear
(PMNs) and platelet (Plt) recovery on the 15th (range 10-22) and 19th (range
11-29) posttranspalnt days, respectively. Acute GvHD (aGvHD) had 13/26
(50%), and chronic GvHD (cGvHD) 10/21 (47.1%) patients. The incidence of
overall TRM was 46.8% (15/32), while early death was noticed in 4 (12.5%)
patients. A cause of death in 9 (28.1%) patients was cGvHD, in 2 (6.25%)
patients infection, and in 3 (9.35%) cases disease-relapse was occurred.
Fourteen (43.7%) of the patients are still alive, 9 from the low-risk group
for TRM, with long-term survival from 1 to 16 years. Patients who received
SCs from peripheral blood (PB) vs bone marrow (BM) had significantly faster
engraftment (p < 0.05), lower oropharingeal mucositis rate (25% vs 70%; p <
0.05), but more frequent cGvHD (83.3% vs 30.3%; p < 0.05). A significantly
improved (log-rank = 2.39; p < 0.01) overall survival (OS) was obtained in
BM-setting. Conclusion. The results obtained in this study are in accordance
with data from analogous clinical trials. Exactly, in the era of the new
target therapy (TKI application), allogeneic SCT can be still a convenient
therapeutic approach for well-selected CMLpatients, especially for those
with initial high-risk disease and lower probability of TRM.

A Sadly Overlooked Lesbian Gem: Hope Thompson's Green
Authors: Gilbert Sky
Published: January 2012

This article is an appreciation of the work of little-known lesbian playwright Hope Thompson—an underappreciated film-maker and playwright in Toronto who has been creating work for the last twenty years. The piece uses Hope's play Green as a starting point for an analysis of her work. The methodology is close reading, but the essay is not strictly an academic research paper; instead it is a loving and impressionistic journey through a unique lesbian feminist script. Hope Thompson's work is radical queer feminist playwriting that, instead of foregrounding female romance and lesbian civil rights, makes a radical case for lesbians as sexual beings who negotiate power in a Foucauldian sense. Her work is also radical because it uses camp adroitly and profoundly. Hope's stylistic quirks are typical of queer male writing and situate her in a very interesting political place in terms of the lesbian canon.

A New Approach to Measure Volatility in Energy Markets
Authors: Ruiz María del Carmen , Guillamón Antonio , Gabaldón Antonio
Published: January 2012

Several measures of volatility have been developed in order to quantify the degree of uncertainty of an energy price series, which include historical volatility and price velocities, among others. This paper suggests using the permutation entropy, topological entropy and the modified permutation entropy as alternatives to measure volatility in energy markets. Simulated data show that these measures are more appropriate to quantify the uncertainty associated to a time series than those based on the standard deviation or other measures of dispersion. Finally, the proposed method is applied to some typical electricity markets: Nord Pool, Ontario, Omel and four Australian markets.
Disruption of Axonal Transport in Motor Neuron Diseases
Authors: Ikenaka Kensuke , Katsuno Masahisa , Kawai Kaori , Ishigaki Shinsuke , Tanaka Fumiaki , Sobue Gen
Published: January 2012

Motor neurons typically have very long axons, and fine-tuning axonal transport is crucial for their survival. The obstruction of axonal transport is gaining attention as a cause of neuronal dysfunction in a variety of neurodegenerative motor neuron diseases. Depletions in dynein and dynactin-1, motor molecules regulating axonal trafficking, disrupt axonal transport in flies, and mutations in their genes cause motor neuron degeneration in humans and rodents. Axonal transport defects are among the early molecular events leading to neurodegeneration in mouse models of amyotrophic lateral sclerosis (ALS). Gene expression profiles indicate that dynactin-1 mRNA is downregulated in degenerating spinal motor neurons of autopsied patients with sporadic ALS. Dynactin-1 mRNA is also reduced in the affected neurons of a mouse model of spinal and bulbar muscular atrophy, a motor neuron disease caused by triplet CAG repeat expansion in the gene encoding the androgen receptor. Pathogenic androgen receptor proteins also inhibit kinesin-1 microtubule-binding activity and disrupt anterograde axonal transport by activating c-Jun N-terminal kinase. Disruption of axonal transport also underlies the pathogenesis of spinal muscular atrophy and hereditary spastic paraplegias. These observations suggest that the impairment of axonal transport is a key event in the pathological processes of motor neuron degeneration and an important target of therapy development for motor neuron diseases.
