Abstract: The aim of present research is to investigate the relation between anxiety and gastric ulcer in a sample of the general population to find whether anxiety can lead to gastric ulcer. The population was 100 people which 50 of them suffered gastric ulcer and 50 of them were people who had no Digestive problems and were healthy. This population has participated in this research by filling Hamilton anxiety scale questionnaire. Results from this research showed: even though anxiety could be seen less among healthy people than people who suffered gastric ulcer but anxiety wasn’t the factor to lead gastric ulcer but it was among the predisposing factors so anxiety didn’t have meaningless difference with gastric ulcer. In this research, Age, sex and education Variables weren’t considered. In this research we don’t have contrast and zero assumption as we are not going to Infer or estimate anything but we want to find whether there is meaningful difference in what we are investigating.

Abstract: Pakistan is facing severe shortage of edible oil. Sunflower can be a good alternative for fulfilling oil requirement due to its ideal characteristics like high oil contents, protein contents and short life cycle. Seed priming is a technique which is used to decrease the harmful effects of different abiotic factors and to increase the seed germination and crop production. It is highly affected by biotic and abiotic stresses like drought, heat, clod, insect/pest attack, fungal, viral and bacterial diseases. There is great loss of yield and productivity of maize due to water stress. The present review will provide its readers an opportunity to understand the breeding procedure to develop drought tolerant varieties and hybrids. Heritability, specific combining ability, dominance effects, heterosis provides a chance to develop hybrid while additive, general combining ability and genetic advance provide chance to develop hybrid for higher grain.

Abstract: In this study, we are concerned with the Mahala Marhoom wastewater treatment plant20.000 m3/day using oxidation ditch techniques for twelve months during 2013 in EL-Garbia governorate-Egypt. Oxidation ditch process is used to treat the municipal and domestic sewage. The purpose of wastewater treatment is to remove the contaminants from wastewater with the objective that it is treated enough to be released back into the environment. The untreated sewage generates fouling smell, harmful bacteria, etc. which is hazardous for public health and degrades the environment by librating noxious gases. An oxidation ditch is a form of extended aeration activated sludge. The aeration basin is a large oval shaped tank that resembles a racetrack. Wastewater enters the ditch and is circulated around the track by means of a large horizontal brush/rotor. The rotor assembly is partly submerged in the ditch. As it rotates it pushes the mixed liquor around the "track". The rotor also provides the needed aeration to maintain a DO level of about 2-3 mg/L in the basin. The oxidation ditch effluent passes to the secondary clarifier and RAS is returned to the ditch. Samples were collected from the influent and the effluents of plants. The samples were analyzed following standard procedures for the determination of BOD5, COD, ammonia, Total Nitrogen, nitrite, nitrate, total phosphorus, TSS, VSS and other parameters. We found the efficiency removal of total nitrogen and phosphorus not high and needed to upgrade. The pilot plant was designed to improve the quality of the effluent so we used biological nutrient removal process.  BNR systems are designed to remove only TN or TP, while others remove both. Bardenpho Process (Four-Stage) – continuous-flow suspended-growth process with alternating anoxic/aerobic/anoxic/aerobic stages and Modified Bardenpho process with addition of an initial anaerobic zone.

Abstract: Humic acids (HAs) are the result of organic matter decomposition and are beneficial to plant growth and development. The integration of organic fertilizers appears to be suitable application for saving chemical fertilizers and reducing environmental pollution. In this study, two field experiments were conducted during two winter seasons 2011/2012 and 2012/2013 to investigate the effect of 16 treatments which were; two common garlic cultivars in Egyptian market Balady and Sids-40, two levels of inorganic fertilizers (100% and 50% of recommended dose) and one level of each compound of the following organic fertilizers; humic acid, fulvic acid and compost on garlic vegetative growth characteristics, yield and its components. Application of organic fertilizers showed superior effect for increasing garlic growth and productivity. Treatments of compost and 50% or 100% of RD inorganic fertilizers improved the plant height and shoot fresh weight. While, application of HAs; humic acid, fulvic acid combined with 100% of RD inorganic fertilizers increased the number of leaves and the shoot dry weight, respectively. The obtained results reflected generally that Balady cv. surpassed the Sids-40 cv. in plant height and high longevity traits, when the high total yield was observed in Sids-40 cv. plants. The highest values of total yield, neck diameter and bulb diameter were detected with garlic plants of Sids-40 cv. treated with 100% RD+humic acid. For the bulbing ratio, application of 50% RD+humic acid gave the highest mean. However, the lowest loss of weight of bulbs was found when garlic plants were treated with 100% RD+fulvic acid. High accumulation of nitrate and nitrite was observed in extracts of both cultivars when treated with 100% RD (control) while, treatments with compost + 50% RD decreased the contents of nitrate and nitrite.

Abstract: In a greenhouse experiment, two strains of plant growth promoting rizobacteria (PGPR) mixture of (ICARDA-441 and ARC-202) as seed inoculants, and white willow (Salix alba) extract as foliar and seed treatment were tested for induction systemic acquired resistance (SAR) in faba bean plants against Bean yellow mosaic virus (BYMV). The results demonstrated that BYMV challenged plants emerged from Rhizobium inoculants seeds and salix extract showed reduction in the level of disease severity of BYMV infection. Significant improvements in faba bean were obtained due to the used Rhizobium leguminosarum (PGPR) as well as salix extract. On contrary, considerable reductions in all tested parameters were occurred as a result of the viral disease. Both PGPR inoculants and soaking treatment with salix extract showed significant increase in abscisic acid (ABA), salicylic acid (SA) and jasmonic acid (JA) levels when being compared with other treatments. The beneficial effects of the used treatments were extended to increase not only total phenol and free proline but also the activities of peroxidase and polyphenoloxidase enzymes in comparison with control plants. PGPR inoculants and salix extract (especially soaking) improved plant health by increasing the pigment contents similar to control values.

Abstract: Most bacterial strains are becoming resistant to multiple antibiotics particularly, Methicillin Resistance Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. This study exhibited the strong antimicrobial activity of T. vulgaris total aqueous extract against Multiple drug resistance pathogenic bacteria including both Gram-positive (MRSA) and Gram-negative (Ps. aeruginosa) bacteria with low concentration of MIC and short time kill assay. Scanning Electron Microscopy (SEM) was conducted to get the images of morphological damages in selected tested bacteria. The SEM images showed that, most cells present damage and observed to get clustered and stick to each other. Gram negative and the Gram positive cells appeared to be shrunk and even some were empty. Furthermore, most of the Gram-negative and Gram positive cells appeared to be stuck together and melted. These images confirm the loss of shape and integrity which was followed by the cell death.

Abstract: All organisms (e.g. bacteria, plants or animals including humans) are exposed everyday to varying amounts of ionizing radiation emitted from radon and its progeny in general environment and in the dwellings. These radiations are spontaneously emitted by naturally occurring radioactive material like 238U and 232Th, ever since their existence on earth. The exposure to alpha radiation emitted from radon poses health hazards not only to workers at industrial units like thermal power plants, coal fields and oil fields but also to the dwellers in normal houses in their surroundings. Radon being an inert gas can easily disperse into the atmosphere immediately on its release. The solid alpha active decay products of radon like 218Po and 214Po become airborne and get themselves attached to the aerosols, dust particles and water droplets suspended in the atmosphere. When inhaled during breathe, these solid decay products along with air may get deposited in the tracho-bronchial and pulmonary region of lungs resulting in the continuous irradiation of the cells which may be the cause of lung cancer. In the present work, we report on the estimation annual effective doses received by the residents living in different types of dwellings. For these measurements we have used the alpha sensitive solid-state nuclear track detectors (SSNTD). The concentration of radon and annual effective doses have been calculated using recommendations from by International commission on radiological protection (ICRP). The results indicate higher radiation dose received by the residents residing in mud and fly ash brick dwellings compared with the residents of cemented and other dwellings.

Abstract: Potentials of some selected isolated microbes from Orita-aperin and Awotan dumpsites leachate to bio-accumulate heavy metal were investigated. Heavy metal content of the samples was determined by atomic absorption spectrophotometer. Microbial enumeration and isolation of the leachate samples were carried out using pour plate technique. Tolerance ability of the microbial isolates to heavy metals was determined by cultivating the isolates at concentrations ranging from 1mM to 5mM on nutrient broth and potato dextrose agar for bacteria and fungi respectively. Based on the result of heavy metal resistant assay, two bacteria and one fungus were then selected to determine their potential to bio-accumulate heavy metal from the leachate under the agitated condition in shaker incubator at 37oC and 200rpm and non-agitation for a period of 10 to 15 days for bacteria and fungi respectively. The total bacteria count of the leachate ranged from 1.9 x 108 to 3.77 x 109CFU/ml while the heavy metal content ranged from 0.001mg/l for chromium and silver to 1.56mg/l for copper. The ability of Bacillus subtilis, Micrococcus luteus and Trichoderma harzianum to tolerate heavy metals at high concentration of 5mM was their basis for selection. Out of the three selected organism Bacillus subtilis was most efficient in the removal of copper with 90.49% and arsenic with 57.7% accumulation under agitated condition, whereas, the values dropped to 37.16% and 7.00% accumulation respectively when left un-agitated. Also the combination of the two bacteria (Bacillus subtilis and Micrococcus luteus) in the experimental set-up when left un-agitated showed relatively high accumulation ability for copper and nickel with 86.71% and 83.3% respectively. The microorganisms used in this study have the potential role in the bioremediation of heavy metals in contaminated aquatic environment by heavy metal containing leachate.

Abstract: The liver function analysis is an indication of liver fitness of a fish and generally reveals the health of the fish. In this study, the liver function tests of fishes (Clarias gariepinus) collected from three different fish ponds designated as A, B, C located in Gwagwalada, Abuja were carried out. A total of ninety (90) live adult C. gariepinus were collected from fish ponds of which thirty (30) were collected from each of three selected ponds. The physio-chemical parameters of the ponds (Temperature, pH, Dissolved Oxygen, Alkalinity, Hardness and Transparency) were determined. The Alkaline Phosphatase (ALP), Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALP) of the fishes were examined using the standard methods. The results obtained showed that the physico-chemical parameters of Pond A and Pond B within the standard limits set by International Regulatory Authority (FEPA) and the liver enzyme markers (ALP, AST, ALT) were within the standard reference values. Furthermore, physico-chemical parameters of Pond C were higher than the set limits by FEPA and also the liver enzymes (ALP, AST, ALT) assessed were significantly higher (P<0.05) than the standard reference values. The findings of this study would be of assistance in improving policy on quality pond management in order to reduce the incidence of fish liver diseases.

Abstract: An automated blood serum chemistry analytical system designed for human usage was employed to establish the levels of urea and creatinine parameters present in sera obtained from 90 experimental groups of channel catfish from three commercial ponds ranging 10.2cm-60cm in length and weight ranging 100grams-900grams. The fish clarias were divided into three groups with varying length and weight. Group 1 contains 30 catfish 10cm-20cm in length and 100grams-300grams in weight, Group 2 contains 30 catfish 21cm-40cm in length and 301grams-600grams in weight and Group 3 also contains 30 catfish 41cm-60cm in length and 601grams-900grams in weight. The results indicated a significant (p ˃ 0.05) increase in creatinine for all the three groups as the weight increases while there was a significant decrease (p ˂ 0.05) in the urea and creatinine levels of the catfish in group 3 recording 0.00mgdL as the lowest Urea Level and 0.00mgdL as the lowest Creatinine level. The maximum level of Urea and Creatinine was recorded as 10.8mgdL and 2.90mgdL respectively and they are obtained from the catfish in group 3 with weight ranging between 601grams-900grams. Using P ˂ 0.05 level of significance, length (cm) is significant to the weight i.e. P ˂ 0.05 (0.00 ˂ 0.05), likewise creatinine. At a significant level of P ˂ 0.05, it shows that length, Urea and Creatinine of the C.gariepinus in group three all depended on their weight. These studies suggest that "normal" values established by any method of sera analysis may be different in the same species depending on the diet, season, and presence of environmental stressors.

Abstract: Objectives: This study sought to evaluate the diagnostic accuracy of 64-slice multi-slice computed tomography (MSCT) for the assessment of in-stent stenosis using conventional coronary angiography as the reference standard. Background: Although promising results have been obtained using 64-slice computed tomography for the detection of coronary artery stenosis in native coronary arteries, as compared with previous-generation of MSCT scanners, but data on the evaluation of coronary stents are scarce. Methods: In 48 patients (42 [88%] male, ages 55 11 years) with previous stent (≥ 2.5 mm diameter) implantation (n = 90), 64-slice MSCT angiography using either Definition dual-source 64-slice, Siemens, [n=14] or Aquilion 64-slice, Toshiba Medical Systems, [n=34]) was performed. At each center, coronary stents were evaluated by 2 experienced observers and evaluated for the presence of significant (≥50%) in-stent restenosis. Quantitative coronary angiography served as the standard of reference. Results: A total of 11 (12%) stented segments were excluded because of poor image quality. In the interpretable stents, 24 of the 79 (30.4%) evaluated stents were significantly stenosed, of which 18 were correctly detected by 64- Slice MSCT. Accordingly, sensitivity, specificity, and positive and negative predictive value to identify in-stent re-stenosis in interpretable stents were 75%, 95%, 86% and 90%, respectively. Conclusions: In selected patients, ISR can be evaluated with 64-slice MSCT with good diagnostic accuracy. In particular, a high negative predictive value of 90% which indicating that 64-slice MSCT may be most valuable as a noninvasive method of excluding in-stent restenosis.

Abstract: Onchocerciasis is a chronic parasitic disease caused by the filarial nematode Onchocerca volvulus and transmitted by female blackfly, Simulium spp. The disease is most prevalent in Africa, where over 99% of the cases occur.  40% of all cases occur in Nigeria. This study assessed the prevalence of onchocerciasis among different age groups and gender in Imeri, an endemic Community in Ondo State, Nigeria. 194 participants of both sexes and not below 10years of age who attended the community clinic were selected for the study. Structured questionnaire was administered to obtain useful epidemiological information from the respondents. Bloodless skin snips were aseptically collected from the iliac crests of the respondents who presented with palpable nodules using sterile blood lancet and razor into saline solution.  The solution was centrifuged at 2000rpm and residues examined for microfilariae under X40 objective lens of a microscope. The highest prevalence of 66.7% was found in age group 71-80years while the least prevalence (22.7%) was found in age group 10-20years. Total prevalence in the community was 32% (n=62). Prevalence among the male (33.3%) was slightly higher than that of the female (30.0%). Occupation such as farming (41.1%) and hunting (37.5%) were found to predispose the respondents to infection in the study area. The results are suggestive of need to increase intensive public enlightenment programmes, especially in local dialect, to educate the community about the aetiology of the disease, and also correct the myth about the drug (ivermectin) in order to eradicate the disease in the community.

Abstract:Background: Bacterial vaginosis is a condition of the vagina caused by an imbalance of naturally occurring bacterial flora, which allows more harmful bacteria to gain a foothold and multiply. The study was carried out to determine the prevalence of bacterial vaginosis and the effect of hygiene practices on the vagina flora. Methodology: One hundred and fifty self-collected vagina swabs were obtained from female students of the University, smeared, Gram stained and scored by the Nugent method. Questionnaire was also administered to each respondent to assess the possible risk factors responsible for the imbalance of the vagina flora. Result: The overall prevalence of BV was 22.5%, 37.3% had intermediate and 40.1 had negative Nugent scores. Among the factors analyzed, douching (p=0.01), multiple sex partners (p=0.0), change of sex partner (p=0.00) and at least three times a week coital frequency (p=0.00) had a significance correlation to the presence of BV. Age and menstrual hygiene and had no significant correlation with the prevalence of BV. Conclusion: There is a need to create awareness to reduce the complication that might occur in future during pregnancy and childbirth by conducting scheduled programs on health education because the study established that certain hygienic practices can be a predisposing factor to bacterial vaginosis and imbalanced vagina flora.

Abstract: Shigellosis is a worldwide health concern especially in developing countries with poor sanitation and has contributed to the increase in the mortality rate of infants. The study reported the antibiotic resistance profiles and characterization of resistance (gyrA, blaCTX) and virulence (Stx1) genes in Shigella sp. recovered from stool samples of diarrhoeal patients in Nigeria. One hundred and forty-eight diarrhoeal patients’ stool samples collected from various health institutions in Ile-Ife, Osun State, Nigeria were examined for the presence of Shigella sp. Isolation was done on Salmonella-Shigella agar plates at 37oC and isolates identity confirmed by conventional biochemical tests. Antibiotic susceptibility of isolates was by Kirby-Bauer’s disc diffusion technique and isolation of plasmid DNA in the multiple antibiotic resistant (MAR) isolates was carried out. Molecular detection of resistance (gyrA) and virulence (Stx) genes was by polymerase chain reaction. A total of 58 Shigella species comprising S. sonnei (37.9%), S. boydii (37.9%), S. flexneri (13.8%) and S. dysenteriae (10.3%) were recovered. Susceptibility to antibiotics was in varying proportions. All isolates were resistant to ceftriazone and resistance was mostly to nitrofurantoin (96.5%), augmentin (94.8%) and amoxicillin 82.2%). Generally, 80% of the Shigella sp was multiple antibiotic resistant (MAR) types, displaying 22 various MAR patterns. Plasmid DNA bands of varying sizes (1.17-23.13 kb) and fluoroquinolone resistance (GyrA -270bp) genes were harboured by all the representatives MAR isolates. None of the selected MAR isolates contained the beta-lactam resistance (BlaCTX) gene. Shiga toxin (Stx- 400bp) was detected in only one of the isolates. The recovery of multiple antibiotic resistant Shigella sp. harbouring large size plasmid DNA and fluoroquinolone resistance gene is of great health consequence.

Abstract: The study was designed to determine the prevalence, direct financial loss and public significance of Ovine hydatidosis in Adama municipal abattoir, Eastern Ethiopia. Both cross-sectional and retrospective studies were conducted from December 2013 to April 2014 at study area. Hydatid cyst count, characterization and financial loss estimation were done on 384 sheep slaughtered in the abattoir. Systematic random sampling was used to select the study animals. Out of 384 sheep inspected, 231(60.2%) were positive for the disease. The infestation of lung, liver, spleen, kidney and heart were 56.1%, 25.6%, 3.70%, 2.44% and 1.21%, respectively. There was statistically significant difference in origin and age of the sheep (P<0.05). Hospital and clinic based retrospective study (from 2011 to 2013) was also performed in Adama Referral Hospital, Hebert clinic and Universal clinic to investigate the prevalence of human hydatidosis. Case book analysis revealed that of the total 121,785 admitted patients for ultrasound examination, 44 (0.03%) hydatid cases were recorded. The study revealed that the disease was highly prevalent and it has both economic and public health significance. Thus, there should be strict routine meat inspection so that infected organs and carcasses can be condemned as well as awareness creation on the community should be done.
