Published: March 2016

Introduction. Orthodontic diagnosis includes the interpretation of the
relations between the craniofacial and cervical system, given the potential
impact of the irregularities from one system to another. Objective. The aim
of this study was to examine morphological characteristics of the cervical
spine, depending on the parameters of the vertical craniofacial growth and
gender in adult subjects. Methods. The sample comprised lateral cephalograms
of 120 subjects with different vertical facial growth, aged 17.5-35 years.
Measured parameters were the following: anterior and posterior vertebral body
height (ABHC2-C5, PBHC2-C5), anterior and posterior intervertebral space
(AISC2-C5, PISC2-C5), distance between vertebrae and point sella (SC2, SC3,
SC4), pterygomaxillare (PmC2), gonion (GoC2) and basion (BaC4); cervical
spine angulation (OPT/CVT) and inclination (OPT/HOR, CVT/HOR). Results.
Results showed that subjects with anterior facial growth rotation have
greater values for BaC4, OPT/HOR, CVT/HOR, OPT/CVT, anterior and posterior
vertebral body heights and intervertebral spaces, and lower values for GoC2
and PmC2. Higher values in males were found for anterior and posterior
vertebral body heights, distances SC2, SC3, SC4, and BaC4. In females, the
greater values were found for GoC2 and ???/?VT. Conclusion. Subjects with
anterior facial growth rotation have greater cervical spine inclination and
angulation, higher cervical vertebrae and intervertebral spaces, longer upper
cervical spines and shorter distances GoC2 and PmC2. Males show smaller
cervical column curvature, but higher cervical vertebrae and greater length
of the upper cervical spine.

Introduction. Data on effects of thrombus aspiration on left ventricular
diastolic function in ST-elevation myocardial infarction (STEMI) population
are scarce. Objective. We sought to compare echocardiographic indices of the
diastolic function and outcomes in STEMI patients treated with and without
manual thrombus aspiration, in an academic, high-volume percutaneous coronary
intervention (PCI) center. Methods. A total of 433 consecutive patients who
underwent primary PCI in 2011-2012 were enrolled in the study. Patients were
not eligible for the study if they already suffered a myocardial infarction,
had been previously revascularized, received thrombolytics, presented with
cardiogenic shock, had significant valvular disease, atrial fibrillation or
had previously implanted pacemaker. Comprehensive echocardiogram was
performed within 48 hours. During follow-up patients? status was assessed by
an office visit or telephone interview. Results. Patients treated with
thrombus aspiration (TA+, n=216) had similar baseline characteristics as
those without thrombus aspiration (TA-, n=217). Groups had similar total
ischemic time (319 ? 276 vs. 333?372 min; p=0.665), but TA+ group had higher
maximum values of troponin I (39.5 ? 30.5 vs. 27.6 ? 26.9 ng/ml; p<0.001).
The echocardiography revealed similar left ventricular volumes and systolic
function, but TA+ group had significantly higher incidence of E/e?>15, as a
marker of severe diastolic dysfunction (TA+ 23.1% vs. TA- 15.2%; p=0.050).
During average follow-up of 14?}5 months, major adverse cardiac/ cerebral
events occurred at the similar rate (log rank p=0.867). Conclusion. Thrombus
aspiration is associated with a greater incidence of severe diastolic
dysfunction in unselected STEMI patients treated with primary PCI, but it
doesn?t influence the incidence of major adverse cardiovascular events.

Published: March 2016

Introduction. Urban life is often followed by immune dysfunction and loss of
immune tolerance in the youngest children. Objective. The study aimed to
determine optimal time efficiency of a synbiotic (5.109 Lactobacillus
acidophilus Rosell-52, Bifidobacterium infantis Rosell-33, Bifidobacterium
bifidum Rosell-71) in controlling respiratory infections and wheezing
disease. Methods. We randomly selected a group of children younger than five
years, hospitalized earlier, and classified them into three groups. Results.
The incidence of respiratory infection before the study was once a month,
while after a threemonth supplementation with the synbiotic children rarely
suffered from respiratory infections, and the state was maintained after
six-month and nine-month supplementations with the synbiotic. The decreased
incidence of respiratory infections was followed by a falling incidence of
concomitant wheezing. A significant increase in tIgA serum was observed in
all groups for only three months, the increase being the highest in children
with recurrent respiratory infections accompanied by wheezing. After a
ninemonth administration of the synbiotic, total IgE serum was lower in all
groups of patients. Conclusion. The optimal duration of administration of
the synbiotic containing three probiotic cultures to provide effective
control of the frequency of respiratory infections was three months, and six
months were required to establish control of the frequency of wheezing. This
synbiotic is useful for immunomodulation in children and is well-tolerated
in young children.

Introduction. Closed reduction and percutaneous pinning are the most widely
used treatment options for displaced supracondylar humerus fractures in
children, but there is still no consensus concerning the most preferred
technique in injuries of the extension type. Objective. The aim of this study
was to compare three common orthopaedic procedures in the treatment of
displaced extension type supracondylar humerus fractures in children.
Methods. Total of 93 consecutive patients (66 boys and 27 girls) referred to
our hospital with Gartland type II or III extension supracondylar humeral
fractures were prospectively included in the study over a six-year period. At
initial presentation 48 patients were classified as Gartland type II and 45
as Gartland type III fractures. The patients were subdivided into three
groups based on the following treatment modality: closed reduction with
percutaneous pinning, open reduction with Kirschner wires (K-wires) fixation,
and closed reduction with cast immobilisation. The treatment outcome and
clinical characteristics were compared among groups, as well as evaluated
using Flynn?s criteria. Results. Excellent clinical outcome was reported in
70.3% of patients treated with closed reduction with percutaneous pinning and
in 64.7% of patients treated with open reduction with K-wire fixation. The
outcome was significantly worse in children treated with closed reduction and
cast immobilisation alone, as excellent outcome is achieved in just 36.4% of
cases (p=0.011). Conclusion. Closed reduction with percutaneous pinning is
the method of choice in the treatment of displaced pediatric supracondylar
humeral fracture, while open reduction with K-wire fixation is as a good
alternative in cases with clear indications.

Published: March 2016

Introduction. Hand injuries caused by corn pickers are relatively rare but in
most cases extensive, with massive tissue destruction. Severe wounds
sustained during agricultural work are contaminated, with high incidence of
infection. Objective. The aim of the study was to determine the frequency and
type of fungal infection in corn picker injuries and their impact on the
course and outcome of treatment. Methods. Corn picker hand injuries for the
period 2006-2012 were analyzed. After setting up clinical suspicion, direct
examination of repeated swabs and histopathological analysis of biopsy
material were done in order to detect fungi. Results. From the total number
of 60 patients, there was a fungal infection in nine of them (which makes 15%
of the total number of patients). Aspergillus spp. was isolated in seven
patients, Candida spp. in three, and Mucor spp. in one patient. None of the
patients had increased risk factors for developing a fungal infection. In
most cases, there was loss of graft and tissue necrosis in previously
normally looking wound, after seven or more days. All patients were treated
with repeated surgical debridement and concomitant parenteral and topical
application of appropriate antifungal agents. There was no need for
reamputation in any patient. Conclusion. A high degree of suspicion and a
multidisciplinary approach are needed for early diagnosis of fungal
infection. Confirmation of diagnosis and the initiation of surgical and
appropriate antifungal therapy are essential for a successful outcome.

Introduction. Infective mononucleosis is most commonly caused by Epstein-Barr
virus (EBV), and in smaller percentage by cytomegalovirus (CMV). Objective.
The aim of this paper was to determine the clinical and laboratory
differences between EBV and CMV infectious mononucleosis in children.
Methods. Cohort retrospective analytical research was conducted. We used data
from medical history in six years period and monitored anamnestic data,
frequency of inspection and palpation obtained data during physical
examination, several laboratory tests, abdomen ultrasonography examination
finding and emergence of disease complications. Statistical processing of
data has been performed using SPSS 20. Results. Total number of examined
children was 137, out of which 85.4% were with EBV and 14.6% with CMV
infection. Affected children were most commonly younger than eight years.
Boys were affected more often. There was no difference in frequency of high
temperature, sore throat, bad breath, and respiratory symptomatology between
examined children. Differences were discovered in frequency of stomachaches,
eyelid swelling, skin rash and fatigue. Differences were not proven in the
frequency of angina, lymphadenopathy and splenohepatomegaly between the
groups. Values of transaminases and lactic dehydrogenases significantly
decreased after seven days of hospitalization in both groups. In children
with EBV, values of transaminases declined faster than in children with CMV.
Anemia and bacterial superinfection of pharynx were most common disease
complications. Thrombocytopenia was more common in children with CMV
infection. Average duration of hospitalization was 6.7 days. Conclusion. In
children with CMV abdominal pain, eyelid swelling, skin rash, fatigue and
thrombocytopenia were more common. In children with EBV values of
transaminases declined significantly faster.

Published: March 2016

Introduction. Hepatitis E is one of the leading clinical manifestations of
acute viral hepatitis in developing countries. In industrialized countries,
during the past several years, sporadic ?autochthonous? cases of HEV
infection have been increased. Objective. The aim of this study was to
analyze the epidemiological, clinical and laboratory features of HEV
infection among patients hospitalized at the Department of Infectious
Diseases in Military Medical Academy, Sofia, Bulgaria. Methods. A
retrospective study of 806 cases of acute viral hepatitis was performed at
the Department of Infectious Diseases in Military Medical Academy, Sofia,
Bulgaria, between December 2004 and September 2012. The etiological diagnosis
was established by ELISA. The statistical analysis was performed using Excel
2007 (Microsoft, Redmond, Washington, USA) and SPSS Statistics 19.0 (IBM
Corp., Armonk, New York, USA). Results. Specific reaction to anti-HEV-IgM and
anti-HEV-IgG antibodies were detected in 20 (2.48%) of 806 patients. The most
observed clinical presentations were jaundice (85%), fatigue (85%), anorexia
(65%), abdominal discomfort (55%) and fever (40%). The mean values of
aspartate transaminase and alanine transaminase were 521 IU/l and 881 IU/l,
respectively. The cholestasis was slight, marked with mean values of
gamma-glutamyl transferase and alkaline phosphatase, respectively 418 IU/l
and 486 IU/l. Conclusion. We report twenty autochthonous sporadic cases of
acute infection with HEV. The zoonotic etiology of the virus as well as the
foodborne transmission of the infection is discussed. We found that aging and
pre-existing underlying diseases are risk factors for a severe course of the
HEV infection.
Doppler changes as the earliest parameter in fetal surveillance to detect fetal compromise in intrauterine growth-restricted fetuses
Authors: Bansal Saloni , Deka Deepika , Dhadwal Vatsla , Mahendru Rajiv
Published: March 2016

Introduction. It is estimated that 3-10% of infants are growth restricted.
Growth disturbances may have long-term issues. Doppler allows insight into
the fetal response to intrauterine stress. Objective. The aim of this study
was to detect fetal compromise in intrauterine growth-restricted (IUGR)
fetuses by means of biophysical profile (BPP) vis-?-vis Doppler velocimetry
studies of the fetal umbilical artery, and to find out which of the two is a
better and earlier predictor of fetal compromise. Methods. A prospective
study was conducted on a total of 50 singleton pregnancies with IUGR between
28 and 42 weeks of gestation. Study patients were managed expectantly with
nonstress testing and amniotic fluid assessment, BPP and Doppler velocimetry
studies of the fetal umbilical artery. Results. Fetal outcome was poor in
5/50 (10%) of the fetuses, defined as presence of all of the following: poor
Apgar test score, neonatal intensive care unit stay, necrotizing
enterocolitis, and low birth weight. Of the four with abnormal BPP, 50% had
poor fetal outcomes. Out of 46 with normal BPP, 6.5% had poor fetal outcomes.
Conclusion. Inference drawn from the study is that the Doppler technology
provides us the opportunity for repetitive noninvasive hemodynamic monitoring
in IUGR pregnancies.

"Stray" achalasia: From gastroenterologist to pulmonologist and back
Authors: Obradovic Dusanka , Joves-Sevic Biljana , Stojanovic Milos , Ilic Miroslav , Ivanov Igor
Published: March 2016

Introduction. Achalasia is a rare esophageal disorder which, due to frequent
presence of both respiratory and gastrointestinal symptoms, can initially be
referred either to pulmonologist or gastroenterologist. Case Outline. A
50-year-old patient was initially referred to gastroenterologist with the
following symptoms: nausea, vomiting, occasional hiccups, weight loss, chest
pain, dysphonia, and dry cough. After chest X-ray, the patient was referred
to pulmonologist with differential diagnosis for pulmonary infiltration and
thoracic aortic aneurysm. Pulmonologist interpreted chest X-ray as showing
paratracheal mediastinal enlargement with air-fluid levels, thus suspecting
achalasia. Computed tomography scan of the thorax with per os contrast showed
extremely dilated esophagus with food stasis. The patient was then referred
to thoracic surgeon, who ordered additional diagnostics (esophageal passage
with contrast, esophagomanometry, esophagogastroduodenoscopy), and finally
performed Heller myotomy. Postoperatively there were no complications, and
the patient was symptom free during the follow-up. Conclusion. Although
achalasia can also result in respiratory symptoms, fastidious anamnesis and
accurate radiological interpretation are essential for the correct diagnosis.
Recent advances in research on non-auditory effects of community noise
Authors: Belojevic Goran , Paunovic Katarina
Published: March 2016

Non-auditory effects of noise on humans have been intensively studied in the
last four decades. The International Commission on Biological Effects of
Noise has been following scientific advances in this field by organizing
international congresses from the first one in 1968 in Washington, DC, to the
11th congress in Nara, Japan, in 2014. There is already a large scientific
body of evidence on the effects of noise on annoyance, communication,
performance and behavior, mental health, sleep, and cardiovascular functions
including relationship with hypertension and ischemic heart disease. In the
last five years new issues in this field have been tackled. Large
epidemiological studies on community noise have reported its relationship
with breast cancer, stroke, type 2 diabetes, and obesity. It seems that
noise-induced sleep disturbance may be one of the mediating factors in these
effects. Given a large public health importance of the above-mentioned
diseases, future studies should more thoroughly address the mechanisms
underlying the reported association with community noise exposure.
Food allergy in children
Authors: Radlovic Nedeljko , Lekovic Zoran , Radlovic Vladimir , Simic Dusica , Ristic Dragana , Vuletic Biljana
Published: March 2016

Food allergy represents a highly up-to-date and continually increasing
problem of modern man. Although being present in all ages, it most often
occures in children aged up to three years. Sensitization most often occurs
by a direct way, but it is also possible to be caused by mother?s milk, and
even transplacentally. Predisposition of inadequate immune response to
antigen stimulation, reaginic or nonreaginic, is of nonselective character so
that food allergy is often multiple and to a high rate associated with
inhalation and/ or contact hypersensitivity. Also, due to antigen closeness
of some kinds of food, cross-reactive allergic reaction is also frequent, as
is the case with peanuts, legumes and tree nuts or cow?s, sheep?s and goat?s
milk. Most frequent nutritive allergens responsible for over 90% of adverse
reactions of this type are proteins of cow?s milk, eggs, peanuts, tree nuts,
wheat, soy, fish, shellfish, crustaceans, and cephalopods. Allergy
intolerance of food antigens is characterized by a very wide spectrum of
clinical manifestations. Highly severe systemic reactions, sometimes fatal,
are also possible. The diagnosis of food allergy is based on a detailed
personal and family medical history, complete clinical examination, and
corresponding laboratory and other examinations adapted to the type of
hypersensitivity and the character of patient?s complaints, and therapy on
the elimination diet. A positive effect of elimination diet also
significantly contributes to the diagnosis. Although most children ?outgrow?
their allergies, allergy to peanuts, tree nuts, fish, shellfish, crustaceans,
and cephalopods are generally life-long allergies.
Effect of Binder Modification on the Performance of an Ultra-Thin Overlay Pavement Preservation Strategy
Authors: Mogawer Walaa S. , Austerman Alexander J. , Underwood Shane
Published: March 2016

The objective of this study was to determine whether asphalt rubber (AR) binders will provide similar or better performance compared with a polymer modified asphalt (PMA) binder when used in a high-performance, ultra-thin lift overlay pavement preservation strategy. Current specifications for these types of overlays normally require the use of a PMA binder, because it has the ability to make these overlays more elastic under traffic loading and is less sensitive to temperature fluctuations. However, several state agencies are looking into the feasibility of incorporating sustainable and environmentally friendly technologies, such as AR binders and warm mix asphalt (WMA) technologies, into their asphalt mixtures, including those used for high-performance, ultra-thin lift overlays. This study examined the effect of binder modification type (AR or PMA) and the influence of the use of WMA in high-performance, ultra-thin lift overlays. In general, the mixtures that were tested provided comparable rutting, moisture damage, and low-temperature cracking performance in the high-performance, ultra-thin lift overlay. However, the use of the AR binders indicated reduced performance compared with the PMA binder in mixture fatigue cracking via the beam fatigue test, and mixture reflective cracking in the overlay tester. The results from the beam fatigue test were not always supported by the fatigue life predictions from the simplified viscoelastic continuum damage model. The only detriment to mixture performance for mixtures incorporating WMA was a reduction in fatigue cracking performance when used with AR binders.
Critical Assessment of the Long-Term Performance and Cost-Effectiveness of a New Pavement Preservation Method: Micromilling and Thin Overlay
Authors: Tsai Yichang (James) , Wu Yi-Ching , Gadsby April , Hines Sheila
Published: March 2016

The Georgia Department of Transportation (DOT) has developed and implemented a new pavement preservation method that uses micromilling in conjunction with a thin overlay for cost-effective replacement of a deteriorated, thin, open-graded surface layer (¾ to 1¼ in.) without removing the sound underlying layer. The new method was first implemented in 2007 on a 15.3 mi section on I-75 near Perry, Georgia, and resulted in significant savings. In considering whether to adopt the new method as standard practice in pavement preservation, it is essential to evaluate the method’s actual, long-term performance. This is the first paper to report the actual, long-term performance of the new method. The study used 8 years of pavement condition data collected by the Georgia DOT and sensing data collected by Georgia Institute of Technology. Based on the data, the pavement on I-75 is still in good condition after 8 years (with 6% raveling in 2015). Based on the current condition and the Georgia DOT’s past experience with open-graded surface mixes, the Georgia DOT anticipates an additional 2 to 3 years of service for the I-75 project. This provides a service interval of 10 to 11 years, which is comparable to that of Georgia’s conventional pavement rehabilitative strategy for open-graded surfaced Interstate pavements, which typically ranges from 10 to 12 years. The equivalent uniform annual cost of the new method is $11,200 per lane-mile per year, which is 11% lower than the $12,600 per lane-mile for the conventional rehabilitation method computed on a 12-year service interval. This information can assist transportation agencies in making decisions about whether to apply the new pavement preservation treatment.
Bi-Level Resource Allocation Framework for Retrofitting Bridges in a Transportation Network
Authors: Lu Jie , Atamturktur Sez , Huang Yongxi
Published: March 2016

Bridges connect roadways over natural barriers to form transportation networks. Retrofitting at-risk bridges is a proactive strategy to reduce the vulnerability of the traffic network in the face of natural and man-made disasters. The challenge lies in the allocation of limited resources to different bridges that must not only capture the structural performance of a bridge, but also the impact of the bridge on a transportation network. This paper present a novel, bi-level resource allocation framework that integrates the network protection problem based on traffic optimization at the network level with the structural enhancement problem at the bridge level to achieve cost-effective retrofit strategies for at-risk bridges. In particular, a stochastic programming model was used at the upper level to allocate resources to the network of bridges considering the improvement in bridge traffic capacity through the allocated budget. At the lower level, finite element models were developed to estimate a relationship between the structural performance of bridges and retrofit levels. This relationship was converted to a traffic capacity–cost relationship and used as an input for the upper-level model. The integrated modeling framework is demonstrated with the Sioux Falls, South Dakota, road network, in which critical factors (such as budget levels) on the retrofit strategy were analyzed.
Accuracy of Ice Melting Capacity Tests: Review of Melting Data for Sodium Chloride
Authors: Nilssen Kine , Klein-Paste Alex , Wåhlin Johan
Published: March 2016

In cold climate regions, chemicals are often applied on roads to facilitate snow and ice removal. A commonly used performance indicator is the ice melting capacity. There is a growing need for stakeholders to measure melting capacity as more commercial products for deicing become available. There are two standardized test methods for measuring melting capacity, SHRP H-205.1 for solid deicers and SHRP H-205.2 for liquid deicers, but there have been concerns that these tests are not accurate. Researchers have developed alternative test methods, including the shaker test, the mechanical rocker test, and the ice cube titration test. This paper summarizes published data on measured melting capacity for sodium chloride (NaCl). The published data were compared with the calculated melting capacity of NaCl. The findings confirm that SHRP tests have low reproducibility and are not able to measure full melting capacity. The newer test methods measured closer to full melting capacity than the SHRP tests did. They also showed improved accuracy, although more data from the newer test methods are needed before conclusions can be drawn.
Proactive Strategy for Variable Speed Limit Operations on Freeways Under Foggy Weather Conditions
Authors: Choi Saerona , Oh Cheol
Published: March 2016

Adverse weather conditions are a critical external factor that threaten traffic safety on freeways. Variable speed limit (VSL) operations can be used as a traffic management tool to harmonize vehicle speed and reduce the likelihood of crashes during adverse weather conditions. This paper proposes a novel VSL operations strategy based on the prediction of weather and traffic conditions, referred to as a proactive VSL operations strategy. The k–nearest neighbors ( k-NN) statistic was used to predict weather and traffic conditions. VSL operations logic, which used visibility distances and safe stopping distances obtained from road weather information systems and average speeds obtained by vehicle detection systems, was developed. The proposed methodology is focused on the restricted visibility distance resulting from foggy weather conditions on freeways. A microscopic traffic simulator, VISSIM, was used to simulate a freeway traffic stream and collect vehicle-maneuvering data. An external application program interface, the VISSIM COM interface, was used to implement the proposed VSL operations strategy. A surrogate safety assessment model was used to derive indirect safety measures to evaluate the effectiveness of the proposed methodology. Total conflicts in the proposed VSL algorithm were reduced in comparison with a system lacking VSL by 19.10% and 27.27% under moderately and severely foggy weather conditions, respectively. These outcomes are expected to be of great use in the development of more effective VSL systems to enhance freeway safety during adverse weather conditions.
Development of a Sensor Platform for High-Accuracy Mapping of Roadway Lane Markings
Authors: Davis Brian , Donath Max
Published: March 2016

This paper documents the development and evaluation of a low-cost, vehicle-mounted sensor suite and processing algorithms capable of automatically detecting and determining the position of lane markings accurate to the 10-cm (4-in.) level. Such map data can be used for many applications, including lane departure avoidance systems based on the global navigation satellite system (GNSS) or GPS, road curvature calculations, automated systems for reapplying lane markings, and high-accuracy road mapping including improving the local base map. The sensor suite used consists of a high-accuracy GNSS receiver, a side-facing video camera, a computer, and mounting hardware. The side-facing camera is used to record video of the ground adjacent to the passenger side of the vehicle. The video is processed with a computer vision algorithm that locates the fog line within the video frame. Vehicle position data (provided by GNSS) and previously collected calibration data are used to locate the fog line in real-world coordinates. The system was tested on two roads (primarily two-lane, undivided highway) for which high-accuracy (<10 cm) maps were available. The offset between the reference data and the computed fog line position was generally better than 7.5 cm (3 in.). The results of this work demonstrate that it is feasible to use a GNSS combined with a camera to detect the position of a road’s fog lines for the development of high-accuracy maps that are useful for many applications.
Piecewise Multiple Linear Models for Pavement Marking Retroreflectivity Prediction Under Effect of Winter Weather Events
Authors: Wang Chieh , Wang Zhaohua , Tsai Yi-Chang
Published: March 2016

Most existing models for prediction of pavement marking retroreflectivity have been developed from data collected in locations with similar weather conditions; therefore, the effect of different weather conditions, such as winter weather events, has not been extensively studied. This study develops degradation models that can predict retroreflectivity of durable pavement marking materials under various winter weather conditions. Piecewise multiple linear models are proposed to explicitly account for the effect of winter weather events in this study. In comparisons of the proposed models with conventional multiple linear models (MLMs) developed from the same set of data, the proposed models outperformed the MLMs, and the overall root-mean-square error improved from 204.6 mcd/m2/lux for MLMs to 106.5 mcd/m2/lux for piecewise MLMs. The proposed models also show robust and consistent results in predicting retroreflectivity of different materials in different states. The results indicate that the proposed method can be adopted by various states and regions for comprehensive retroreflectivity prediction under various weather conditions.

Authors: Trivedi DR , Joshi AG , Nagar PS
Published: March 2016

Seeds of Radermarchera xylocarpa and Dolicandrone falcata were soaked overnight in water and germinated in different substrates. In both the plants, the highest percent of germination was recorded in cocopeat (Radermarchera xylocarpa:62%; Dolicandrone. falcata: 41%) followed by MS basal medium (Radermarchera xylocarpa: 46%; Dolicandrone falcata:20%), cocopeat: sand (Radermarchera xylocarpa:30%; Dolicandrone. falcata: 8%) and least being in filter paper (Radermarchera xylocarpa: 23%; Dolicandrone falcata: 0%).Prior to germination in optimised substrate, seeds were soaked overnight in distilled water (control) and in gibberllic acid (GA3) (5 & 10 ?M). In both the plants GA3 treated seeds failed to increase percent germination and the growth of seedlings. In control the seedling growth was better with respect to all the parameter for both the species. Seedlings which were grown in cocopeat, rapidly developed into healthy plants after transfer to field Bangladesh J. Sci. Ind. Res. 51(1), 41-46, 2016

Authors: Miah MA , Ahmed S , Uddin MS
Published: March 2016

Stable performance of maize hybrids at a specific growing region is critical for obtaining high and stable yield. The objectives of this study were to assess grain yield stability of fourteen maize inbred lines from five different diverse regions of Bangladesh during 2010 - 2011 growing season (rabi) using genotype main effect plus genotype by environment interaction (GGE) biplot and to identify maize inbred lines that have both high mean yield and stable yield performance across test environments of Bangladesh. The GGE biplot method was effective in recognition that the inbreds G2 and G13 to be the most desirable ones for growing in Jessore (E1), G6 and G8 in Gazipur (E2), G3 in Rahmatpur (E3) and G1, G12, G14 and G9 in Debiganj (E5) region. The inbreds G5 and G7 had average grain yield and high stability, whereas the inbred line G10 had high grain yield and high stability. Besides, the inbred line G13 was the least stable across different environments. This technique can serve as a useful tool for recommendation of maize inbreds for specific growing regions taking into account the specificities of hybrids and growing conditions.Bangladesh J. Sci.

Published: March 2016

An in vitro regeneration protocol of Adhatoda vasica has been developed using excised nodal segments and juvenile leaves for multiple shoots regeneration directly or through callus induction. Explants were cultured on MS medium with different concentrations of IAA, NAA, BAP, GA3 and Kn singly or in combinations. MS medium supplemented with BAP (10.0 mg/l) was found best for multiple shoot formation, in which 93.33% explants produced multiple shoots. After two months, maximum number of multiple shoots were 10.6 ± 1.82, highest length of plantlets was 5.2 ± 2.20 cm. 100% calli formation were observed on MS medium supplemented with IAA (0.05 mg/l) + NAA (0.05 mg/l) + BAP (1.0 mg/l). Callus initiation started after 14 days and gave light green colored callus. Best callus mediated shoot regeneration was found on MS+10.0 mg/l BAP medium. Root induction of in vitro raised shoots was best on ½ MS + IBA (1.0 mg/l). Well rooted plantlets were transferred to plastic pots containing garden soil and compost in a ratio of 2:1 for hardening. The ultimate survival rate under natural condition was about 80%.Bangladesh J. Sci. Ind. Res. 51(1), 75-80, 2016

Fragaria iinumae Makino is recognized as an ancestor of the octoploid strawberry species, which includes the cultivated strawberry, Fragaria ×ananassa Duchesne ex Rozier. Here we report the construction of the first high‐density linkage map for F. iinumae. The F. iinumae linkage map (Fii map) is based on two high‐throughput techniques of single nucleotide polymorphism (SNP) genotyping: the IStraw90 Array (hereafter “Array”), and genotyping by sequencing (GBS). The F2 generation mapping population was derived by selfing F. iinumae hybrid F1D, the product of a cross between two divergent F. iinumae accessions collected from Hokkaido, Japan. The Fii map consists of seven linkage groups (LGs) and has an overall length of 451.7 cM as defined by 496 loci populated by 4173 markers: 3280 from the Array and 893 from GBS. Comparisons with two versions of the Fragaria vesca ssp. vesca L. ‘Hawaii 4’ pseudo‐chromosome (PC) assemblies reveal substantial conservation of synteny and colinearity, yet identified differences that point to possible genomic divergences between F. iinumae and F. vesca, and/or to F. vesca genomic assembly errors. The Fii map provides a basis for anchoring a F. iinumae genome assembly as a prerequisite for constructing a second diploid reference genome for Fragaria.

Two decades after the discovery of 51 Peg b, the formation processes and atmospheres of short-period gas giants remain poorly understood. Observations of eccentric systems provide key insights on those topics as they can illuminate how a planet’s atmosphere responds to changes in incident flux. We report here the analysis of multi-day multi-channel photometry of the eccentric (

) hot Jupiter HD 80606 b obtained with the Spitzer Space Telescope. The planet’s extreme eccentricity combined with the long coverage and exquisite precision of new periastron-passage observations allow us to break the degeneracy between the radiative and dynamical timescales of HD 80606 b’s atmosphere and constrain its global thermal response. Our analysis reveals that the atmospheric layers probed heat rapidly (∼4 hr radiative timescale) from

to 1400 K as they absorb

of the incoming stellar flux during the periastron passage, while the planet’s rotation period is

hr, which exceeds the predicted pseudo-synchronous period (40 hr).
Percutaneous Angioplasty of the Sole Patent Cerebral Artery in Two Patients with Takayasu's Aortoarteritis
Authors: Varghese Kiron , Adhyapak Srilakshmi M.
Published: March 2016

We report two female patients with Takayasu's aortoarteritis, who presented with symptoms of cerebral ischemia due to critical stenosis of the sole patent cerebral artery. Both had occlusion of both vertebral arteries and one carotid artery with critical stenosis of the other carotid artery and presented with hemiparesis contralateral to the patent but stenosed cerebral artery. They also had transient ischemic attacks attributable to the culprit vessel. In the first patient, balloon angioplasty alone was not successful, and hence, a self-expanding stent was deployed in the right common carotid artery. In the second patient, successful balloon angioplasty was performed for the left common carotid artery. Distal protection devices were not used, and neither patient experienced any periprocedural neurological event. Clinical follow-up at six months revealed no significant cerebral events.
Mechanisms behind the Resistance to Trastuzumab in HER2-Amplified Breast Cancer and Strategies to Overcome It
Authors: Luque-Cabal Maria , García-Teijido Paula , Fernández-Pérez Yolanda , Sánchez-Lorenzo Luisa , Palacio-Vázquez Isabel
Published: March 2016

The introduction of trastuzumab therapy markedly improved the poor prognosis associated with HER2-amplified breast cancers. Despite this, the presence of primary and acquired resistance to trastuzumab treatment remains a significant common challenge. The identification of resistance mechanisms and the incorporation of new drugs that achieve a better blockade of HER family receptors signaling have resulted in improved outcomes. The phosphatidylinositol 3'-kinase/protein kinase B/mammalian target of rapamycin pathway, cross-talk with estrogen receptors, immune response, cell cycle control mechanisms, and other tyrosine kinase receptors such as insulin-like growth factor I receptor are potential pathways involved in trastuzumab resistance. Different therapeutic interventions targeting these pathways are currently under evaluation.
Increasing granular flow rate with obstructions
Authors: Murray Alan , Alonso-Marroquin Fernando
Published: March 2016

We describe a simple experiment involving spheres rolling down an inclined plane towards a bottleneck and through a gap. Results of the experiment indicate that flow rate can be increased by placing an obstruction at optimal positions near the bottleneck. We use the experiment to develop a computer simulation using the PhysX physics engine. Simulations confirm the experimental results and we state several considerations necessary to obtain a model that agrees well with experiment. We demonstrate that the model exhibits clogging, intermittent and continuous flow, and that it can be used as a tool for further investigations in granular flow.Received: 22 November 2015,  Accepted: 19 February  2016; Edited by: L.

Introducción

En Latinoamérica el trauma es la principal causa de muerte. Esta situación social obliga a optimizar los sistemas de información para implementar sistemas de atención en trauma. En Cali se inició el registro de trauma de la SPT. Se presenta el reporte del primer año en dos hospitales de alta complejidad de la ciudad.

Metodología

Se realizó un análisis descriptivo de los datos obtenidos del registro de trauma en dos hospitales de la ciudad, uno privado (FVL) y otro publico (HUV), en el período comprendido entre el 01-01-12 y el 31-12-12, incluyendo información demográfica, mecanismos de trauma, severidad (ISS) y mortalidad.

Resultados

Se registraron 17.288 pacientes, 10.417 (60,26%) en FVL y 6.871 (39,74%) en HUV, el promedio de edad fue 29,9 ± 19,8 años. Menores de 18 años 4.920 (28,5%), y 6.777 (39,2%) entre los 18–35 años. La sospecha de violencia fue 0,8% en FVL vs 28,7% en HUV. Las lesiones relacionadas al trabajo fueron 49% la FVL vs 5,6% el HUV. Se hospitalizaron el 29,7% (5.131), de ellos, 1251 (12%) en FVL y 3.880 (56,5%) en HUV. 463 pacientes requirieron UCI en FVL (4,4%). y 194 en HUV (2,8%). El mecanismo más frecuente, las caídas con 37,2%. El mecanismo mas letal fueron las HPAF. La mortalidad global fue del 444 (2,6%), 112 (112%) en FVL y 332 (4.8%) en HUV.

Conclusiones

En el primer año se registraron 17.288 pacientes, las características del trauma son muy similares en el hospital público y el privado. Encontrándose una baja mortalidad en ambos pero mas hospitalizaciones en el publico, asociados a un mayor numero de muerte de moderada severidad. Se logro la implementación de un registro de trauma en Colombia.

Introducción

Los accidentes son la primera causa de mortalidad y el principal problema de salud pública a nivel mundial en niños mayores de un año, dado el impacto de las discapacidades permanentes que ocasionan las lesiones traumáticas en los niños. En Colombia, la mayoría de los traumatismos en pacientes pediátricos pueden ser evitados, por lo cual es importante la implementación de estrategias de promoción y prevención que podrían reducir la incidencia de casos en trauma hasta en un 80%.

Objetivo

Estimar el panorama del trauma pediátrico y los mecanismos de lesión, identificando posibles estrategias de prevención a futuro, en dos hospitales de la ciudad de Cali en el año 2012.

Metodología

Estudio descriptivo retrospectivo con población del registro de trauma en el año 2012 <18 años en dos hospitales de Cali (HUV y FVL). Se toman como variables la información socio-demográfica, la etiología, lugar del evento y región anatómica afectada.

Resultados

Se registraron 4920 pacientes (28,5%). El promedio de edad fue 9 (±5,2) años; el 12,1% fueron lactantes, el 16,2% pre-escolares, el 46,3% escolares y el 25,4% adolescentes. Siendo las calles, avenidas y el domicilio los lugares más frecuentes del evento, las primeras causas de consulta fueron las caídas n = 2647 (56,3%) y el aplastamiento n = 567 (12,1%). Las zonas más afectadas fueron los miembros superiores n = 1421 (28,9%) y el 21,4% (n = 1054) fueron heridas múltiples. El 26,6% (n = 1072) se hospitalizaron y el 2,4 requirió UCI. La mortalidad global fue del 1,2%, secundaria principalmente a lesión por arma de fuego 12,9% (35/271).

Conclusiones

La causa principal de consulta fueron las caídas (56,3%); la mortalidad estuvo asociada a lesiones por arma de fuego. Implementar el registro de trauma pediátrico facilita la búsqueda de medidas de prevención para minimizar el riesgo de accidentes causados por factores predecibles creando conciencia e interés del impacto social, económico y familiar que se genera.
