Abstract :

The Hardy Weinberg’s Law states that the allele frequency remains constant in a population. When we consider gene frequencies as p and q, the genotype frequencies will be p2, 2pq and q2 for homozygous dominant, heterozygous dominant and homozygous recessive respectively. In this present study 650 samples of individuals were analyzed from Himachal Pradesh, India  (Rohru, Shimla, Kangra, Manali and Una). Out of total of 16 characters considered 12 characters showed higher degree of deviation than expected on applying chi square test hence, showing that forces like natural selection, genetic drift, mutation, non random mating, etc. have a more profound effect in the distribution of population in an area.

Abstract :

Gastroesophageal reflux disease (GERD) represents a real social problem in the western world.  Brazilian consensus conference considered GERD to be “a chronic disorder related to the retrograde flow of gastro-duodenal contents into the esophagus and/or adjacent organs, resulting in a spectrum of symptoms, with or without tissue damage”. However, gastro-esophageal refluxate contains a variety of other noxious agents, including pepsin. Currently, it is recognized that this component of the refluxate (commonly called bile reflux and identified by the Bilitec bile reflux monitor using bilirubin as a marker) is composed of bile salts and pancreatic enzymes, and is also injurious to the esophageal mucosa. It causes symptoms, and could be linked to the development of Barrett’s esophagus and esophageal adenocarcinoma. A highly efficient barrier exists between the stomach and the esophagus formed by the lower esophageal sphincter, the diaphragm, the His angle, the Gubaroff valve and the phrenoesophageal membrane. The most important factors at work in preventing reflux include, well the lower esophageal sphincter, esophageal clearance mechanisms that limit contact time with noxious substances, and mucosal protective factors intrinsic to the esophageal mucosa. The most common cause of gastroesophageal reflux is an excessive exposure of the esophagus to gastric secretions during Transient Lower Esophageal Sphincter Relaxation. pH-metric studies in healthy subjects have shown that primary peristalsis is the most important mechanism of clearing after acid reflux in orthostatic position. When the subject is in supine position, however,most reflux is neutralized by means  clearance produced by secondary peristalsis. Several studies have shown that oesophageal function is impaired in patients with reflux oesophagitis, especially in high grade oesophagitis. Patients with reflux oesophagitis have reduced lower oesophageal sphincter pressures, an increased incidence of failed peristalsis, reduced distal peristaltic amplitudes, slower velocity of propagation and in some studies shorter duration of contractions. In conclusion, application of the 24hour ambulatory oesophageal pressure and pH monitoring technique did not show any differences in either pH profiles or motility variables before and after healing of reflux oesophagitis. The fact that oesophageal motility does not change after healing of oesophagitis supports the hypothesis that abnormalities in motility are pre-existent rather than the consequence of the inflammation. It could be argued, however, that the inflammation has caused irreversible changes in the oesophageal wall.

Abstract :

Chest and abdomen radiographs are the most common examinations in paediatric radiology. It is important to ensure that patient radiation dose is kept to low level without image quality degradation. In this work, the effective dose, risk and image quality were assessed in chest and abdomen radiography. Eighty children (40 boys, 40 girls) participated in the study and they were categorized in four age groups, according to their anatomical characteristics. The dose and risk were estimated utilizing the PCXMC 2.0 code. The image quality was assessed by two radiologists based on image features provided by the CEC guidelines.   The mean effective dose value was 13 μSv and 34.6 μSv for chest and abdomen, respectively. The risk was slightly higher in the case of 1 y age group. Image quality values were similar for all age groups, with a slight increase in chest radiographs compared to abdomen radiographs. Improved image quality values were obtained for the processed images, for both chest and abdomen radiographs.

Abstract :

Although many heat treatment schemes have been developed for pearlitic steel, in the literature there is still little information about the influence of the different heat treatment parameters on the percentage, properties and morphology of the phases. Neither there is any information on matching the parameters, taking into account the different degree of deformation of the steel wires, the particular applications and operating conditions of the products. The aim of this research was to optimize the parameters of the interoperation annealing used during the cold plastic working of pearlitic steel intended for cold-drawn wires. The results of the mechanical properties and microscopic observations, presented in this paper clearly show that there is no need to apply long recrystallization treatments to small diameter wires. This finding is highly significant from the economic point of view and it clearly shows the importance of the individual matching of heat treatment parameters to specific industrial applications.

Abstract :

The evolution that one can see in e-commerce, with the internet playing the main role as the best way to implement information and communication channels, to make the electronic transactions more effective, linking extranets and extending intranets to a commercial partnership environment has produced impact on what regards internal control. According to the specific characteristics of the Internet, the path taken by a transaction is not easily predictable nor is it possible to assure the security of all systems that participate in an electronic commercial transaction performance. Taking in consideration what has been said above, it is impossible to guarantee a safe electronic commercial transaction environment, by using only technological components (firewalls, for instance). Therefore, we have to conclude the need for the implementation of risk based internal control systems, which take in consideration the new internal control pattern, when commercial transactions are to be made electronically.

Abstract :

The study aimed to conduct a diagnosis of the hygienic-sanitary conditions of food and beverage sector of hotels in Pelotas/RS and interventions based on the concepts of Best Practices. During the period of September 2012 to January 2013, a diagnostic of hygienic sanitary conditions through the application of the Ordinance No. 78/2009 check list and an intervention through a training course for food handlers was conducted. It was calculated the percentage of adequacy of hotels, as a very good level (Group 1) above 90%, from 75% to 90% as a good level (Group 2), acceptable level between 50% and 75% (Group 3) and below 50% as unsatisfactory level (Group 4). The main results showed an increase of the percentage of the items covered after the intervention in two of the hotels, demonstrating that the training may have contributed to the improvement of hygienic sanitary conditions in them. The improvement of some items was also verified when analyzed in individual blocks from the check list after the training in each hotel. Nevertheless, it was also noticed that there still are several inadequacies, demonstrating the need for greater attention from those responsible for food and beverage services in hotels.

Abstract :

This paper deals to the enhancement of the polyester woven's hydrophilicity using a green process. Firstly, we have functionalized the polyester surface by air atmospheric plasma using a Dielectric Barrier Discharge DBD system. The results of the water contact angle (°) and capillarity (%) demonstrate the improvement of the hydrophilicility of polyethylene terephtalate surface. The durability of hydrophilicity improvement was investigated by grafting Sericin on the plasma treated polyester surface. Besides, the zeta potential measurements and X-ray Photoelectron Spectroscopy (XPS) analysis were performed to confirm the hydrophilic character imparted to the polyethylene terephtalate surface by the introduction of polar groups after air atmospheric plasma treatment and Sericin grafting. The morphologies of  samples fabrics  were studied by a scanning electron microscopy (SEM).

Abstract :

The in vitro production of bovine embryos has dramatically increased in recent years. From the first calves produced entirely from IVEP (in vitro embryo production)until today, the in vitro embryo production systems have been modified and improved. The media for embryo production generally are formulated with nutrient excess and furthermore it is known that excess nutrients can have negative effects on embryo development. In order to assess the actual metabolic needs of the gametes and embryo, we decided to evaluate energy consumption with a non-invasive technique, proton nuclear magnetic resonance (1H-NMR) during gamete co-incubation. In the first experiment we evaluated the behavior of cumulus oocytes complex (COCs), sperm and COCs plus sperm. We chose to evaluate pyruvate, lactate and alanine. The effect of the different groups was significant only for pyruvate (p>0.05) otherwise we did not find any difference in alanine and lactate concentrations. The concentration of pyruvate is significantly decreased in COCs and semen + COCs. After this experiment we re-formulated the IVF (in vitro fertilization) medium by changing the concentration of pyruvate and lactate (to 1/3 and 1/10 of standard concentrations) based on the metabolic results. The reduction of pyruvate and lactate had a positive effect on embryo production, which was evident by the increase (P<0.05) of advanced stage embryos in the modified vs. control media (39.6% vs. 30.4% respectively). These results suggest that this new formulation improves embryo development. These results can be used to change recommended concentrations of these substrates in IVF media.

Abstract :

Objective: Giving the sensitivity of brain tissue to ischemic or hemorrhagic suffering, a patient with a  cerebrovascular accident (CVA) needs to be treated as a medical urgency in the emergency room (ER). To treat the patient accordingly to his medical urgency a triage system is of great importance.

Methods: A monocentric, retrospective study with a pretest-posttest design has been completed to examine the influence of the Manchester Triage System (MTS) on the trajectory of patients with a CVA. Different (time)variables have been compared. The nature of the research was to determine if the implementation of the MTS had a positive impact on the trajectory of a patient with a CVA. SPSS Statistics 21 is used for the execution of the analytical tests.

Results: The results of the research shows that patients that were singed in to the ER, on who the MTS was used, got faster medical attention by a nurse (p < 0,001). Though with little or no influence on the patient trajectory. The influence on the outcome of the trajectory of a patient with a CVA on the other hand was marginal. The estimated probability for a better outcome was increased by 2% after the implementation of the MTS (p = 0.775).

Conclusion: The implementation of the MTS is insufficient to provide a more accurate and faster care. More efficient and targeted interventions are necessary on the trajectory of a patient with a CVA.

Abstract :

Genome-wide association studies of psoriasis identified interleukin (IL)-12B and IL-23R as significantly associated loci with psoriasis, thus emphasizing to the important role of these genes in the pathogenesis of this disease and have influenced the development of medications that specifically target these key immunological players. Here we report an association study of a homogeneous Greek cohort from the island of Crete, consisting of 100 patients with PS and 195 controls, which were genotyped for rs3212227 and rs6887695 SNPs of the IL-12B and the rs7530511 and rs11209026 SNPs of IL-23R genes, respectively, using Taqman assays. Neither IL12B nor IL23R SNPs showed any association with psoriasis in the population under study. Apart from the previously reported evidence for the role of IL-12B and IL-23R in various populations, our results demonstrate no association of these gene polymorphisms with psoriasis in the Cretan population, thus highlighting the importance of comparative studies in different populations to confirm the previously detected genetic associations.

Abstract :

An advanced transitional turbulence model () has been applied to the simulation of the typical hypersonic flows in the present investigation, which is corrected with empirical correlation for the transition consideration. Combining PSE (stability analysis equation) with eN prediction method, it has been studied how to find out the position of the most unstable flow within the boundary layer, so that the transition empirical correlation parameters would be more appropriate for the specified flow while being independent of designer’s experiences. The typical hypersonic flow field over a blunt cone has been simulated, through which it could be found that both the computational results of the wall heat flux and boundary layer transition region agree well with the experimental results. Besides t, both the interaction between shock wave with the boundary layer on a flat plat, and the flow across a compression corner have been simulated by the same model as well. It was found that the present methods are also applicable for the simulation of complicated flow with shock wave/boundary layer interaction, and the results turned out to be superior to those employing traditional turbulence models.

Abstract :

Currently, aquaculture based employment has been impact on fishery industry and gained awareness in worldwide. Northern parts of Thailand, cage fish farming are very important cultivation. It has contributed substantially to livelihoods, food demand, employment and income. Environmental factors are significant role in the fish culture especially, the temperature. It is fairly low in the Northern part of Thailand during in the winter, air temperature drops below 15 °C and difference between day and night about 15-20 °C. Generally, the appropriate and optimum temperature of fish culture was 28-32 °C. The average initial weight of fishes were 2.54±0.11 g at cultured for 120 days in 3 treatments, normal fish cage (T-A), greenhouse fish cage (T-B) and greenhouse fish cage was integrated with reduce heat loss system (T-C). The study investigation revealed that average water temperature and highest value were observed in treatments (T-C) (27.6 °C), followed by treatments (T-B) (26.7 °C) and treatments (T-A) (26.4 °C), respectively. After 120 days of culture, fishes in treatments (T-A) had significantly higher weight (121.35±5.33 g/fish) then treatments (T-B) (135.05±5.66 g/fish) and treatments (T-C) (143.87±5.07g/fish). Compared with treatment (T-C) with treatments (T-A) and (T-B) achieved more daily weight gain, equal to 16.1% and 6.8%, respectively. Also the specific growth rate was equal to 4.17% and 1.49%, respectively. Furthermore, the study focused on increasing and provides the optimum temperature using thermal performance of greenhouse fish cages integrated with hot air aerator through solar energy. In this study, Climbing perch (Anabas testudineus) fish was used. The system was developed for heating the fish cages with solar energy by greenhouse cage design is equipped with insulation to reduce heat loss by used foam and covered with bamboo which is economically helpful for fish farmer. Consequently, the results confirmed that possible to apply and increase water temperature through greenhouse fish cage integrated with reducing heat loss system.

Abstract :

Nanocomposites CeO2/5wt.% NiO, CeO2/Pt and CeO2/5wt.% NiO-Pt with different Pt loading were produced by the extractive-pyrolytic method (EPM) and characterized by XRD and SEM. NiO and Pt were deposited on a carrier (CeO2 nanopowder) by thermal decomposition of nickel hexanoate and n-trioctylammonium hexachloroplatinate, respectively. XRD analysis showed that in CeO2/5wt.% NiO nanocomposites the mean size of nickel oxide crystallites increases (from amorphous to 18 nm) when the pyrolysis temperature increases from 300 ºC to 700 ºC. In CeO2/ Pt nanocomposites with the Pt content from 0.3 wt.% to 2.4 wt.%, both with NiO and without it, the Pt particles are X-ray amorphous. With a higher metal content (4.8 wt.%) in CeO2/NiO-Pt composites, the mean size of Pt crystallites was 4 nm that is twice less if compared with the CeO2/Pt composite. The produced nanocomposites were tested in glycerol oxidation processes by molecular oxygen. It has been found that CeO2/Pt and CeO2/5 wt.% NiO-Pt composites are catalytically active in alkaline glycerol water solutions. It was shown that the Pt weight loading (0.3 – 1.2 %) in the composites significantly affected the glycerol conversion (12 – 68 %). The main product of oxidation was glyceric acid.

Abstract :

An increasing body of evidence supports the concept that inflammation plays a major role in the development and progression of atherosclerosis which in lower extremities leads to peripheral vascular disease. We hypothesized that inflammatory markers, WBCs, neutrophils, IL-6 and TNF-α would be associated with ABI, a hallmark of atherosclerotic burden.

Research designs and methods: Among 60 type 2 diabetic patients, 35 were diagnosed for PVD (ABI ≤0.9), mean age 51.58±11.38 yrs, and 25 were without PVD (ABI >0.9), mean age 54.66±6.52 yrs. Serum concentrations of IL-6 and TNF-α were determined by enzyme linked immuno-sorbent assay.

Results: ABI was lower in PVD patients then without PVD (0.677±0.13 v/s 1.27±0.41, p<0.001, respectively). By linear regression analysis, TNF-α and IL-6 were significantly co-related with ABI in an inverse manner (β= -0.006, p= 0.030, β= -0.005, p= 0.018) respectively. There was no significant co-relation of ABI with WBCs and neutrophils.

Conclusion: ABI was strongly associated with PVD in type 2 diabetic patients. This study demonstrated that ABI was associated with IL-6 and TNF-α concentration with an inverse pattern making them prominent markers of inflammatory cascade involved in atherosclerosis.
