Authors: Pereira Thuanny Lúcia , Corassa Anderson
Published: February 2015

Objetivou-se descrever o fluxo de suínos para abate produzidos no Estado de Mato Grosso entre os anos de 2008 e 2012. Foram utilizados dados de 9.426.729 suínos produzidos no Estado de Mato Grosso e transportados para abate de janeiro de 2008 a dezembro de 2012, no qual realizou-se análise descritiva das informações, com frequências de origem e destino; machos e fêmeas em função dos meses e anos e as distâncias percorridas. Observou-se crescimento no número de viagens e de suínos transportados do Estado de Mato Grosso, com valores médios de 19,83 e 19,61% no período avaliado, respectivamente. Registou-se uma variação de 142,73 a 147,42 de suínos transportados por viagem. As frequências de transporte a distâncias inferiores à200 km aumentaram, enquanto a frequência acima de 500 km reduziram. Portanto, conclui que ao longo dos anos houve alterações quanto ao volume de animais, distância e percursos, no qual, aumentou o volume de suínos transportados, reduziu o volume de suínos transportados a longa distância, e houve implantação de unidades frigoríficas mais próximas ao local de produção. Desta forma, 73,47% dos suínos para abate transportados percorreram entre zero e 200 km da origem ao destino, e a média ponderada de distânciafoi de 205,74 km.

O mercado pentecostal de pregações e testemunhos: formas de gestão do sofrimento
Authors: Cortês Mariana
Published: February 2015

O presente artigo tem como objetivo investigar a emergência de um mercado pentecostal de pregações e testemunhos, no qual sujeitos engajam-se nas carreiras de "pregadores-itinerantes", vivendo do expediente de "dar seu testemunho" em igrejas e eventos. Narrando episódios dramáticos de seu passado mundano, esses sujeitos lutam para se inserir nas margens de um mercado religioso instituinte, transformando suas biografias despedaçadas em mercadorias simbólicas. Nessa indústria pentecostal do sofrimento, sujeitos considerados "subprodutos" da modernização são absorvidos por suas qualidades de "resto", por aquilo que suas identidades estranhas portam de ambivalência. Observa-se assim a constituição de um mercado de sofrimentos, uma das mais surpreendentes invenções desta forma de capitalismo religioso à brasileira, em que o "anômalo" é transmutado em alavanca de acumulação.
Mídia e performances de gênero na Igreja Universal: O desafio Godllywood
Authors: Teixeira Jacqueline Moraes
Published: February 2015

Este artigo tem por finalidade mapear e descrever algumas práticas relacionadas à produção de uma performatividade do feminino mimetizada em formas de falar, de se apreender e de experienciar os corpos a partir da circulação de imagens na internet, em páginas da Igreja Universal do Reino de Deus (IURD) voltadas para o público feminino. Meu objetivo ao recuperar essa interação é pensar o papel que a mídia, de modo geral, e as tecnologias da internet, de modo particular, têm na formação de tais performatividades, ora por meio de linguagem de gendramento dos gêneros, ora mediante tecnologias de poder que conformam a sujeição e a subjetivação dos sujeitos.
Weed Control in Soybean as Influenced by Residual Herbicide Use and Glyphosate-Application Timing Following Different Planting Dates
Authors: DeWerff Ryan P. , Conley Shawn P. , Colquhoun Jed B. , Davis Vince M.
Published: February 2015

Soybean planting has occurred earlier in the Midwestern United States in recent years; however, earlier planting subjects the crop to longer durations of weed interference. This may change the optimum timing of POST glyphosate applications, or increase the need for residual herbicides applied PRE to optimize yield. A field study was conducted in 2012 and 2013 near Arlington, WI to determine the effect of planting date, residual herbicide use, and POST glyphosate timing on weed control and soybean yield. Planting dates were late April, mid-May, and early June. A PRE application of sulfentrazone plus cloransulam was applied to half the plots following each planting date. Glyphosate was applied POST to all plots at the V1, V2, V4, or R1 soybean growth stage. Planting date and glyphosate timing did not affect soybean yield in this study. However, averaged across years, planting dates, and POST glyphosate timings, yield increased from 3,280 to 3,500 kg ha−1when a PRE herbicide with residual soil activity was used. In POST-only treatments, delaying the planting date to June decreased weed density at POST application timing from 127 to 5 plants m−2(96%) and from 205 to 42 plants m−2(80%) in 2012 and 2013, respectively. Where a PRE was used, total weed density at POST application timing was always less within planting date, and also declined from early to late planting date 26 to 3 plants m−2(89%) and 23 to 6 plants m−2(74%) in 2012 and 2013, respectively. In conclusion, both PRE herbicide use and delayed soybean planting were effective strategies to reduce the number of in-crop weeds exposed to POST glyphosate and should be considered as strategies to reduce the number of weeds exposed to POST herbicides for resistance management.

Photocatalytic and photoelectrochemical inactivation of Escherichia coli and Staphylococcus aureus
Authors: Ribeiro Marcela Alves , Cruz Jaqueline Matos , Montagnolli Renato Nallin , Bidoia Ederio Dino , Lopes Paulo Renato Matos
Published: February 2015

Water disinfection usually requires expensive chemicals or equipment. Chlorination is a common disinfection method, although it is not able to inactivate all pathogens. High concentrations of residual chlorine also cause an unpleasant taste and smell in drinking water. As an alternative, photocatalysis and photoelectrochemical treatment has a high disinfection potential in drinking water by using solid catalysts, such as titanium dioxide. Highly reactive hydroxyl radical generated during the process serves as the main oxidant, capable of inactivating a wide range of microorganisms. In this study, we proposed a novel comparison between Gram-positive and gram-negative microorganisms. An immobilized TiO2 film promoted higher efficiency in water disinfection processes. The treatment effectively inactivated Escherichia coli and Staphylococcus aureus bacterial microorganisms in a shorter period than other alternative methods.
Attachment behaviour of inorganic particles on fibrous media: combined effects of dissolved organics and divalent cations
Authors: Majumdar Udayan , Dagaonkar Manoj V.
Published: February 2015

A systematic study was carried out to investigate the attachment of inorganic particles to fabric media in the presence of divalent cations and the dissolved organics in water, on filter media, or on both. The presence of organics (humic acid, HA) reduced the attachment of inorganic particles on the fabric. Specific attachment trends were observed for the inorganic particles–fibre system. For [CaCl2] < 500 ppm, the particle attachment was lower in the presence of 10 ppm of HA compared to its absence. At [CaCl2] ≥ 500 ppm, the attachment in the presence or absence of HA was similar, suggesting that the attachment was independent of the presence of HA. It was also found that the particle attachment to the fabric was lower when HA was present in water compared to when present on the fabric, suggesting that the attachment behaviour of inorganic particles was dependent on water chemistry (i.e. presence of calcium ions and organics in water), which also altered the surface properties of filter media. The removal trends were explained on the basis of particle aggregation, surface charge and Derjaguin–Landau–Verwey–Overbeek (DLVO) theory.
Quantitative assessment of residential water end uses and greywater generation in the City of Al Ain
Authors: Chowdhury Rezaul K. , El-Shorbagy Walid , Ghanma Mwafag , El-Ashkar Assem
Published: February 2015

Diversification of water sources and water demand reduction are two vital tools in maintaining the security of urban water supplies in the United Arab Emirates (UAE). Reuse of greywater for non-potable end uses can be an effective alternative, but this resource has not yet received much attention in the UAE. Since the generation of greywater significantly differs from country to country – depending on age, gender, habits, lifestyle, living standards and the degree of water abundance – an attempt was made to estimate internal water consumption and greywater generation in the city of Al Ain, UAE. The frequency and water requirement for personal water uses (e.g. showers, ablutions, teeth brushing, hand washing, face washing and toilet flushing) and family water uses (e.g. laundry, dish washing and house cleaning) were estimated from about 100 villa-type detached homes randomly distributed across the city. A frequency analysis was carried out using normal, lognormal, gamma and logistic distribution. The estimated average generation rate of greywater was found to be 192 litres per capita per day, which is about 69% of the average internal water consumption. The generated greywater originates from showers (49%), ablutions (18%), laundry (10%) and washbasins (23%). Based on average quantities, it was shown that the generated greywater is sufficient to fulfil the non-potable water demand in houses, but further, more rigorous, investigation is required.
Engineered biofiltration for ultrafiltration fouling mitigation and disinfection by-product precursor control
Authors: Azzeh Jamal , Taylor-Edmonds Lizbeth , Andrews Robert C.
Published: February 2015

A pilot-scale study was conducted to evaluate the impact of several biofiltration enhancement strategies in terms of organic removal to reduce disinfection by-product (DBP) formation potential and mitigate ultrafiltration (UF) fouling. Strategies included nutrient addition (nitrogen and phosphorus) to optimize metabolic degradation of organics, use of hydrogen peroxide (H2O2, peroxide) to improve filter run times, and the application of in-line aluminum sulphate (alum) for biopolymer removal. The impact of media type on performance was also examined (anthracite versus granular activated carbon (GAC)). Passive biofiltration (without enhancement) reduced dissolved organic carbon (∼5%), biopolymers (∼20%), and trihalomethane and haloacetic acid precursors (∼20% and ∼12%, respectively) while mitigating UF irreversible fouling (∼60%). Nutrient addition was not observed to enhance biological performance. Addition of 0.5 mg/L hydrogen peroxide decreased head loss by up to 45% without affecting organic removal; however at a dosage of 1 mg/L, it negatively impacted both UF fouling and DBP precursor removal. In-line alum addition prior to biofiltration (<0.5 mg/L) improved UF fouling control by up to 40%, without sacrificing head loss. Overall, GAC provided superior performance when compared to anthracite.
N-nitrosamines, emerging disinfection by-products of health concern: an overview of occurrence, mechanisms of formation, control and analysis in water
Authors: Kadmi Y. , Favier L. , Wolbert D.
Published: February 2015

The presence of N-nitrosamines in water bodies used for drinking water purposes may present a more serious risk for humans than regulated disinfection by-products (DBPs) species. Hence, understanding and controlling the incidence of N-nitrosamines represents a contemporary challenge to the water industry. Although many of these molecules potentially formed as DBPs are detected in chlorinated natural waters, few studies have focused on the formation, occurrence, and analysis of N-nitrosamines. Until now, nine N-nitrosamines have been detected in water samples; N-nitrosodimethylamine is the most frequently reported nitrosamine in drinking water. Although there are currently no federal regulations for these molecules in drinking water, this family of N-DBPs is one of three potential groups of contaminants highlighted for possible regulatory action in the near future. This paper gives an overview of the current knowledge concerning the occurrence, precursors, and formation mechanisms of N-nitrosamines in water. In addition, the existing regulations are described and relevant analytical methods used for their quantification in water samples are also discussed.
Evaluation of statistical sampling for the assessment of residential consumption totals in water distribution networks
Authors: Fortunato A. , Arena C. , Mazzola M. R.
Published: February 2015

The paper provides insights into stratified sampling, a standard statistical technique that may be employed to assess domestic water use in water distribution networks. The basic idea is to use only a few meters to provide inference on the total water consumption of a network or of a district metered area through the knowledge of some additional stratification variables, such as household typology, size and occupants number. Since any sampling procedure assumes that the variance of the variable at stake is known, either a suitable amount of past consumption data is necessary, or a specific preliminary survey must be carried out, in order to define the sampling plan. An application with real consumption data from a small municipality in Sicily (Italy) shows that number of occupants for each household is sufficient to design an effective sampling plan and that the methodology can be successfully applied in the technical practice, thus allowing a dramatic reduction of the number of customer meters to be read in order to quantify total water consumption compared to standard practice based on the reading of all meters.

Published: February 2015

This paper presents the long-term data of patients that have been treated with an unconventional implant placement protocol to avoid an invasive surgery when edentulism was caused by an impacted tooth. In 2009, the follow-up of this unconven-tional protocol was 2 to 3.5 years; this article documents now the long-term 5- to 8-year follow-up of 3 patients and 5 im-plants. Over this period of time, implant stability was maintained without complications. This unconventional protocol opens intriguing possibilities; however, more patients with long-term follow-up are warranted before endorsing it in routine appli-cation. Nonetheless, it might suggest that there is still room to revisit one of the leading concepts in dental implantology.
MiR-139-3p is related to left ventricular hypertrophy and cardiomyocyte apoptosis in two-kidney one-clip hypertensive rats

Published: February 2015

MicroRNAs (miRNAs) are important post-transcriptional regulators of gene
expression in many physiological and pathological processes. Previous studies
have reported the role of miR-139-3p in cancer. However, its specific roles
and functions in the heart undergoing hypertrophy have yet to be fully
elucidated. In the present study, a significant upregulation of miR-139-3p
expression was demonstrated in the left ventricular myocardium of two-kidney
one-clip (2K1C) hypertensive rats using microarray and quantitative real-time
PCR (qRT-PCR). Based on computational analysis, we observed that miR-139-3p
can control the expression of mitogen-activated protein kinase 1 (MAPK1) as a
target gene, which is essential for the induction of cardiac hypertrophy and
cardiomyocyte apoptosis. This study provides first information that the
highly expressed miR-139-3p might be closely involved in MAPK1-mediated
cardiac hypertrophy and cardiomyocyte apoptotic processes in 2K1C rat.
Psychological aspects of pediatric anesthesia
Authors: Draskovic Biljana , Simin Jovana , Kvrgic Ivana
Published: February 2015

Surgery and anesthesia cause a significant emotional stress in both parents
and children. Since the consequences of this stress develop immediately after
surgery and can last even when the hospital treatment is over, the role of
the anesthesiologist is to ensure psychological as well as physiological
well-being of the patient. In order to reduce emotional stress induced by
anesthesia and operation, the anesthesiologist has to understand certain
developmental phases that children go through and to identify situations
which a child could potentially see as a danger or a threat. This can usually
be achieved by careful preoperative assessment and by administering
preoperative sedation. During the preoperative visit to the patient, the
anesthesiologist can evaluate the levels of anxiety of both parents and
children as well as assess the child?s medical condition.

Fractal harmonic law and waterproof/dustproof
Authors: Kong Hai-Yan , Chen Rou-Xi , He Ji-Huan
Published: February 2015

The fractal harmonic law admits that the friction between the pure water and
the moving surface is the minimum when fractal dimensions of water in
Angstrom scale are equal to fractal dimensions of the moving surface in micro
scale. In the paper, the fractal harmonic law is applied to demonstrate the
mechanism of waterproof/ dustproof. The waterproof phenomenon of goose
feathers and lotus leaves is illustrated to verify our results and
experimental results agree well with our theoretical analysis.
Polyvinyl alcohol/starch composite nanofibers by bubble electrospinning
Authors: Liu Zhi , He Ji-Huan
Published: February 2015

Bubble electrospinning exhibits profound prospect of industrialization of
macro/ nano materials. Starch is the most abundant and inexpensive
biopolymer. With the drawbacks of poor strength, water resistibility, thermal
stability and processability of pure starch, some biodegradable synthetic
polymers such as poly (lactic acid), polyvinyl alcohol were composited to
electrospinning. To the best of our knowledge, composite nanofibers of
polyvinyl alcohol/starch from bubble electrospinning have never been
investigated. In the present study, nanofibers of polyvinyl alcohol/starch
were prepared from bubble electrospinning. The processability and the
morphology were affected by the weight ratio of polyvinyl alcohol and
starchy. The rheological studies were in agreement with the spinnability of
the electrospinning solutions.
Properties of the flow around two rotating circular cylinders in side-by-side arrangement with different rotation types
Authors: Tu Cheng-Xu , Bao Fu-Bin , Huang Long
Published: February 2015

The field characteristics of two side-by-side rotating circular cylinders in
a cross-flow is investigated under different rotation types, at T/D =
1.11,1.6, and 3, respectively (T is the center spacing between the cylinders,
and D is the cylinder diameter). A similar flow pattern which is the most
efficient to narrow the lowpressure area is identified for rotation type A,
independent of T/D ratio, and two typical flow patterns are found under
different spacings for rotation type B and type C, respectively. It is
confirmed that there is an optimal rotational speed of 1.7-2, under rotation
type A to attenuate the vortices, velocity drop, and turbulence intensity
tremendously. As rotational speed increases to the optimal value, both the
velocity drop and turbulence intensity decrease and their distributions are
smooth. The results indicate that the shear layers which are accelerated
following the free-stream direction would have significant influence on the
flow modification, and different rotation types actually arrange these shear
layers in diverse ways to change the flow pattern. Pitch ratio is capable to
transform the gap flow, which is usually including the shear layers referred,
thus this parameter can modify the wake of the two cylinders at different
rotation types.
Discharge coefficient of small sonic nozzles

Published: February 2015

The purpose of this investigation is to understand flow characteristics in
mini/micro sonic nozzles, in order to precisely measure and control miniscule
flowrates. Experimental and numerical simulation methods have been used to
study critical flow Venturi nozzles. The results show that the nozzle?s size
and shape influence gas flow characteristics which leading the boundary layer
thickness to change, and then impact on the discharge coefficient. With the
diameter of sonic nozzle throat decreasing, the discharge coefficient
reduces. The maximum discharge coefficient exits in the condition of the
inlet surface radius being double the throat diameter. The longer the
diffuser section, the smaller the discharge coefficient becomes. Diffuser
angle affects the discharge coefficient slightly.
Vulnerability of assessing water resources by the improved set pair analysis
Authors: Yang Xiao-Hua , He Jun , Di Cong-Li , Li Jian-Qiang
Published: February 2015

Climate change has tremendously changed the hydrological processes with
global warming. There are many uncertainties in assessing water resources
vulnerability. To assess the water resources vulnerability rationally under
climate change, an improved set pair analysis model is established, in which
set pair analysis theory is introduced and the weights are determined by the
analytic hierarchy process method. The index systems and criteria of water
resources vulnerability assessment in terms of water cycle, socio-economy,
and ecological environment are established based on the analysis of
sensibility and adaptability. Improved set pair analysis model is used to
assess water resource vulnerability in Ningxia with twelve indexes under four
kinds of future climate scenarios. Certain and uncertain information quantity
of water resource vulnerability is calculated by connection numbers in the
improved set pair analysis model. Results show that Ningxia is higher
vulnerability under climate change scenarios. Improved set pair analysis
model can fully take advantage of certain and uncertain knowledge, subjective
and objective information compared with fuzzy assessment model and artificial
neural network model. The improved set pair analysis is an extension to the
vulnerability assessment model of water resources system.

Published: February 2015

Urban bio-retention system is meaningful in reducing rainfall runoff and
enhancing infiltration capacity. But the moisture migration in bio-retention
systems are not clear under climate change. The spatial and temporal
distribution of moisture under different rainfall events in bio-retention
systems are studied in this paper based on experimental data in Beijing.
Richards model is introduced to simulate the spatial and temporal
distribution of moisture including pressure head, hydraulic head and water
content under different initial and boundary conditions. As a result, we
found that from the depth of the node to the lower boundary, the values of
pressure head and hydraulic head increase with depth and decrease with time,
while the values of water content represent opposite trends relative to the
distribution of pressure head and hydraulic head in bio-retention systems.
Modeling of sea spray droplets in the ocean
Authors: Zhu Jian-Bin , Wan Zhan-Hong , Wang Xiao-Chun , Lü Lin
Published: February 2015

Droplets are known to play an important role in momentum, heat, and moisture
transfer between the ocean and atmosphere. A lot of scholars and experts aim
to investigate the effects of droplets on the climate and make precise
forecast for hurricane conditions. So the profiles of droplets concentration
at different heights above the sea surface are important. For a better study
of the momentum and energy transport among the boundary layer, we also need
to know the distribution of droplets with different radii. After wave break,
with the coupled effects of inertia, gravity, wind updraught, and turbulent
mixing, droplets can be transported to certain heights above the sea surface.
In the present study, we develop a modified subgrid-scale flow field model
coupled with the large eddy simulation to investigate the profiles of spay
droplets concentration after wave break. The results in our simulation show
that, the distribution of the droplets with the same radii in vertical
direction is roughly Gaussian distribution, and the maximum appears at the
height nearly above the significant wave height. For different radii, the
concentration of droplets with larger radii can be higher than that of the
smaller ones at some heights. Since the droplets in our model only include
the spay droplets generated by wave break, the data will not be identical
with the measurement in the open ocean and laboratory, which include all the
kinds of droplets above the ocean.
Control of the gelation process of silk fibroin solution
Authors: Liu Yu , Zhang Ying
Published: February 2015

In the present study, silk fibroin solution was controlled through a simple
shearing to accomplish the steady and rapid gelation process and the
conformational transition. Antheraea yamamai silk fibroin was formed into
hydrogels quicker than Bombyx mori silk fibroin on the same condition.
Comparing with Bombyx mori silk fibroin, the rapid gelation of Antheraea
yamamai silk fibroin was concerned with its alternate polyalanine-containing
units which are tended to form the ?-helix structures spontaneously. The
entropic cost during the conformational transition to ?-sheet is less than
that from random coil to ?-sheet.

Published: February 2015

The thermal property of closed-cell aluminum foam is studied numerically and
the effects of the distribution of the circular pore on the thermal property
are studied theoretically. When the convection and radiation are ignored, the
effects of porosity, cell size, and distribution forms of pore on the
apparent thermal conductivity are investigated. Moreover, the effects of air
in the pore on the thermal property are analyzed as well. Simulation results
show that apparent thermal conductivity linearly increases with the increase
of porosity, while the cell size and the distribution have negligible effects
on the thermal property. By comparison, thermal conductivity of air has
slight effect on thermal property of foamed aluminum in the context of small
size pore.
Thermodynamic comparision of R744/R600a and R744/R600 used in mid-high temperature heat pump system
Authors: Fan Xiao-Wei , Ju Fu-Jun , Zhang Xian-Ping , Wang Fang
Published: February 2015

The mid-high temperature heat pump provides hot water at a relatively high
temperature using some industrial waste heat as its source. Now, the main
refrigerants in this application are CFC114, HCFC123, and HCFC142b, etc.,
which are scheduled to be phased out due to their high ozone depletion
potential and global warmth potential. Some studies have been conducted to
find an eco-friendly alternative. In this paper, the natural non-azeotropic
mixtures R744/R600a and R744/R600 are analyzed as alternatives. The
performance of the heat pump system using new mixture is discussed and
compared with those with CFC114, HCFC123, and HCFC142b. Under the given
operating conditions, the maximum heating COP should occur at the mass
fractions of 18/82 for R744/R600a and 10/90 for R744/R600. Both of their COP
are higher than those with the refrigerants of CFC114, HCFC123, and
HCFC142b. The COP and volumetric heating capacity of the system with
R744/R600a are superior to those with R744/R600.
A novel design method for ground source heat pump
Authors: Dong Xing-Jie , Gu Bo
Published: February 2015

This paper proposes a novel design method for ground source heat pump. The
ground source heat pump operation is controllable by using several
parameters, such as the total meters of buried pipe, the space between wells,
the thermal properties of soil, thermal resistance of the well, the initial
temperature of soil, and annual dynamic load. By studying the effect of well
number and well space, we conclude that with the increase of the well number,
the inlet and outlet water temperatures decrease in summer and increase in
winter, which enhance the efficiency of ground source heat pump. The well
space slightly affects the water temperatures, but it affects the soil
temperature to some extent. Also the ground source heat pump operations
matching with cooling tower are investigated to achieve the thermal balance.
This method greatly facilitates ground source heat pump design.

Introduction. Triple renal pelvis is an extremely rare variation of the renal
collecting system. To the authors? knowledge, bilateral triple renal pelvis
has not yet been described in the literature. Case report. A 55-year-old man
was hospitalized due to papillary bladder cancer, detected on
ultrasonography. As incidental finding, intravenous urography revealed
bilateral triple renal pelvis. Six weeks after transurethral resection of the
bladder tumor (TURB) the patient was admitted again, for the second TURB.
Computed tomography- urography confirmed the presence of bilateral triple
renal pelvis. Conclusion. The unique case of bilateral triple renal pelvis
was presented as an extremely rare variation of the renal collecting system.

Authors: Lee Lorraine S. , Green Edmund
Published: February 2015

This paper develops research opportunities associated with Enterprise Risk Management (ERM) using systems thinking as a theoretical foundation. The main objectives of this paper are to advocate incorporating a systems thinking perspective into traditional ERM frameworks and to identify research opportunities associated with systems thinking and ERM. Given the limitations of existing ERM processes, systems thinking represents a possible method for improving ERM.

Published: February 2015

Objective: 

To assess the bone support of the teeth adjacent to a cleft using cone-beam computed tomography (CBCT).

Materials and Methods: 

The CBCT scans of 31 patients with unilateral cleft lip and palate (UCLP) were assessed. The data for teeth neighboring the cleft were compared with those of contralateral noncleft teeth. For each tooth analyzed, the distance between the cementoenamel junction (CEJ) and the bone crest (AC) at the buccal side was measured as was the thickness of the buccal bone level at 0, 1, 2, and 4 mm.

Results: 

The bone thicknesses of the central teeth at the cleft region at the crest and 2 mm apically were statistically significantly thinner than that of the central incisor at a noncleft region. The CEJ-AC distance for central teeth at the cleft region was higher than that for central teeth in a noncleft region.

Conclusions: 

Subjects with UCLP showed reduced bone support at teeth neighboring the cleft compared with controls. This may cause some problems during orthodontic treatment.
The Basic Helix-Loop-Helix Transcription Factor NEUROG3 Is Required for Development of the Human Endocrine Pancreas

Neurogenin3 (NEUROG3) is a basic helix-loop-helix transcription factor required for development of the endocrine pancreas in mice. In contrast, humans with NEUROG3 mutations are born with endocrine pancreas function, calling into question whether NEUROG3 is required for human endocrine pancreas development. To test this directly, we generated human embryonic stem cell (hESC) lines where both alleles of NEUROG3 were disrupted using CRISPR/Cas9-mediated gene targeting. NEUROG3−/− hESC lines efficiently formed pancreatic progenitors but lacked detectible NEUROG3 protein and did not form endocrine cells in vitro. Moreover, NEUROG3−/− hESC lines were unable to form mature pancreatic endocrine cells after engraftment of PDX1+/NKX6.1+ pancreatic progenitors into mice. In contrast, a 75–90% knockdown of NEUROG3 caused a reduction, but not a loss, of pancreatic endocrine cell development. We conclude that NEUROG3 is essential for endocrine pancreas development in humans and that as little as 10% NEUROG3 is sufficient for formation of pancreatic endocrine cells.

Leiomyomas (fibroids or myomas) are benign uterine tumors of unknown etiology. Fibroids are most common in women aged between 30 and 40 years, but they can occur at any age. At present, laparoscopic myomectomy is the most appropriate surgical technique for patients with fertility disturbances. We conducted a prospective study, in which a number of 72 patients diagnosed with uterine fibromatosis and infertility were investigated for the impact of laparoscopic myomectomy (i.e. intramural and subserosal fibroids), the fertility rate and the average time for the appearance of pregnancy. The patients were randomly divided into 2 groups: Group 1, consisted of 36 patients with infertility and uterine fibroids associated in which laparoscopic myomectomy it was practiced, and Group 2, consisted of 36 patients, having the same diagnosis who refused surgical ablation. From the 36 patients which were operated, 11 had intramural fibroids and 25 had presented one or more subserosal fibroids (Group 1). The fertility rate was 25% for patients with no surgery (Group 2) comparing with 86.5% for patients with laparoscopic myomectomy (Group 1, 54.5% for patients with intramural fibroids and 32% for patients with subserosal fibroids). The average time of the appearance of the pregnancy was 23 months for the patients which were not operated (Group 2), and 35.2 months for patients with laparoscopic myomectomy (Group 1, 19.2 months for the patients with intramural fibroids and 16 months for the patients with subserosal fibroids). Our study shows that laparoscopic myomectomy improves the fertility rate compared to non-surgical treatment in the case of patients with uterine fibroids and infertility.

Dental abfraction is a pathological process which causes a loss of dental hard substance. Etiopathogenesis is related to occlusal stress that causes microfractures in enamel and dentin in the cervical region. The restoration treatment is made using aesthetic adhesive materials, but must take into account the causal factors and the specific area where the restoration is done.

Coming from a female pacient's point of view, breast cancer is a hard to bare diagnosis. But what about the male patient? Although is very rare, male breast cancer does exist, and in the majority of cases, it is diagnosed in a very advanced stage with minimal curative posibilities. The critical medical education in our country along with the absence of a well structured national screening program are both provocative factors for the existence of this kind of disease.

This work is based upon a retrospective study on 976 patients (919 females and 57 males) who were diagnosed and requiring medical treatment for mammary neoplasm between 2008-2013 under the auspices of the Surgery Clinic inside the Clinical and Emergency District Hospital of Constanta.

From all the patient's anamnestic common elements like smoking, liver diseases, stress, radiation exposure, family antecedents that are related to the actual suffering, we can draw a latiogeneral instalation pattern of cancer. This study is meant to point out the similarities and especially the differences between the specialised bibliography and the collected information from the existing pathology concerning the age incidence, the type of neo formation, the location, histo-pathologic diagnosis, the types of surgical procedures and also to make evident the causes producing delay in starting the surgical treatment with visible consequential effects on both surviving and the quality of life.

Published: February 2015

Semi-arid environments are characterized by low soil organic matter, lack of sufficient precipitation and occurrence of high temperatures at the terminal of growing season. Effects of foliar application of salicylic acid (SA) and ascorbic acid (AS) during vegetative and reproductive stages at three farmyard manure (FYM) rates (zero (FYM1), 15 (FYM2), 30 (FYM3)t·ha-1) were studied on the growth and yield components of lentil (Lens culinaris Medik.) under supplemental irrigation of semi-arid highland in the north-west of Iran. The results revealed that application of farmyard manure especially at high level could significantly increase the morp-ho-physiological traits such as plant height, first pod height, plant canopy spread, rooting depth, the number of root nodules, ground cover, chlorophyll content and relative water content. Although improving effects of SA and AS on growth parameter were less than FYM, plants treated with SA showed better performance than plants treated with AS. A similar status was observed for grain yield and yield component. So the highest grain yield was recorded at FYM by foliar application of SA. It can be concluded that FYM3 as the most promising manure application rate was adopted to improve both root and total above-ground plant growth. Also this work highlights the importance of exogenous application of growth regulators in lentil cropping systems in semi-arid region with the Mediterranean climate.
