Antibiotic resistant bacteria pass between humans, between animals and between humans and animals in both directions, the use of antibiotics in poultry has contributed to multiple antibiotic resistant in pathogenic bacteria and use of two antibiotics might prevent the emergence of resistance to either. In this study, synergistic effect of combined antibiotics against multidrug resistant human pathogenic bacterial isolates from poultry droppings in Akure, Nigeria was examined. Collection of samples, isolation and identification of bacteria were carried out using standard microbiological method, antibiotic sensitivity test was performed by disc diffusion method and zone of inhibition was used to interpret the sensitivity test as resistant, susceptible or intermediate while combined effects of two antibiotics were investigated by macrobroth dilution and checkerboard assay methods while the synergetic effects of combined antibiotics were calculated using Fractional Inhibitory Concentration (FIC) and percentage synergistic interaction was calculated. All the ten (10) species of bacterial isolates were multidrug resistant and are less resistant to ofloxacin. The highest percentage synergistic interactions observed were Ofloxacin + Amoxicillin (90%), Ciprofloxacin + Amoxicillin (90%), Tetracycline + Amoxicillin (70%), Tetracycline + Augmentin (80%), Cotrimoxazol + Amoxicillin (50%), Cotrimoxazol + Augmentin (70%), Chloramphenicol + Amoxicillin (70%) and Chloramphenicol + Augmentin (80%). Poultry droppings is a potential source of human pathogenic bacteria, high frequency of multiple antibiotic resistance bacteria observed in this study is of great treat to man as this may cause the treatment of infection caused by these bacteria to be difficult. Combination of beta-lactam antibiotic with fluoroqunolones, tetracycline, Chloramphenicol and Cotrimoxazole was synergetic and this will reduce dose related toxicity and prevent resistance to single antibiotic.

Plants and plant materials have been used for thousands of years to treat and control erectile dysfunction in men. This practice has spanned many cultures and traditions around the world, with the therapeutic effects of many plants attributed to their phytochemical constituents. This review explains how polyphenols (including phenolic acids, flavonoids, terpenoids, carotenoids, alkaloids and polyunsaturated fatty acids) in plants and plant food products interact with key enzymes (phosphodiesterase-5 [PDE-5], angiotensin-converting enzyme [ACE], acetylcholinesterase [AChE], adenosine deaminase [ADA] and arginase) associated with erectile dysfunction. By modulating or altering the activity of these physiologically important enzymes, various bioactive compounds from plants or plant products can synergistically or additively provide tremendous protection against male erectile problems.

Background:The negligence of health education and promotion has contributed to increase in morbidity and mortality of malaria among children. Method:This study was carried out in selected secondary schools in Akure, South-western Nigeria to assess the level of awareness, knowledge and perceptive of the use of treated mosquito nets among children of age group 9 and 17 years. 200 pieces of questionnaires were distributed randomly to the respondents. Results and Discussion:Demographic information of respondents, awareness, knowledge and perception on malaria was obtained. 96% of the respondents know that mosquito transmits malaria parasite. The respondents' knowledge on the symptoms of malaria as persistence headache was 94% while 6% wrongly said itching and bleeding were among the symptoms of malaria. 74% have experienced mosquito bites while 26% haven't experienced it. Sleeping under treated net by the respondents was poor as only 2% of them always sleep under insecticide treated net and 44% never sleep under it. Although, awareness of malaria among the secondary school students is high, there is a high percentage (%) of the respondents who never sleep under insecticide treated net. Conclusion:Therefore, health education on awareness of insecticide-treated net should be emphasised for successful elimination of malaria.

Discipline and ethics are twin issues that tend to undermine the provision of quality education in tertiary institutions in Nigeria. This is because the overall goals of tertiary institutions as enunciated in the National Policy of Education can hardly be achieved by all the stakeholders without strict conformity and adherence to the rules and regulations and the ideals of the entire society. The adherence is essential for the general welfare of the society. This paper critically x-rayed the causes of indiscipline in tertiary institutions in Nigeria. Such courses include laxity in home control and parental supervision, school, teacher and societal factors as well as government influence.The paper recommended among others such strategies as enculturation, acculturation as well as acquisition of a certain number of generic skills for dealing with discipline and ethical issues in tertiary institutions in Nigeria.

The goal of this study was to develop bread and biscuit from mixture of wheat and pigeon pea flours and examine the nutritional quality of the two products. The composite flour blend was formulated using wheat and pigeon pea flours in ratio 90:10, 80:20 and 70:30 (wheat: pigeon pea). The samples produced were designated as PWB1, PWB2 and PWB3 for bread while for biscuit the designations were PWb1, PWb2 and PWb3 respectively. For the control samples 100% of wheat flour was used and the samples were designated as PWB0 for bread and PWb0 for biscuit. Samples were analyzed for proximate, minerals and vitamins content using standard analytical procedures of AOAC. Mean data were compared using ANOVA at P< 0.05. The Crude protein (CP), Fat and Ash content of PWB0 (%) were; 10.19, 2.26 and 1.91, respectively. PWBI, PWB2 and PWB3 ranged from 11.69-14.21 CP, 2.82-3.69 fat and 2.09-2.62 ash. PWb1, PWb2 and PWb3 ranged from 14.40-16.19 CP, 8.02-8.15 fat and 1.53-2.01 ash. The proximate composition of bread and biscuit made from composite flour improved significantly at 70:30 formulation (P=.05) compare to the control. The calcium, potassium and zinc content of PWB0 (mg/100 g) were; 54.95, 261.70 and 0.30 respectively. PWBI, PWB2 and PWB3 ranged from 75.50-116.30, 276.05-351.40 and 0.37-0.43. PWb0, PWb1, PWb2 and PWb3 also followed similar trend. Similarly, there was significant increase in β-carotene, thiamine, and riboflavin as the levels of pigeon pea flour increased. Addition of pigeon pea flour to wheat flour clearly enhanced the nutritional composition of the two products except for the reduction in iron and iodine content.

Introduction: Andrographis paniculata (Burm. f.) is a significant pharmacological plant and regularly used in different parts of the world. The antibacterial activity of the methanol leaf extract of A. paniculata against bacterial consortia from blood of diabetic patients was evaluated in this study. Methods: The enumeration of bacteria from blood samples of diabetic patients and their antibiotic sensitivity pattern were done using standard techniques. The phytochemical analysis of A. paniculata methanol extract and antibacterial assay of the extract were also done using standard methods. Results: Staphylococcus aureus had the highest occurring rate of 19.56 % while Klebsiella pneumoniae had the lowest occurring rate of 0.40 %. The isolates exhibited different sensitivity patterns to conventional antibiotics. There were variations in the zones of inhibition of A. paniculata methanol extract against the bacterial isolates as extract showed concentration was dependent on antibacterial activity with all the bacterial isolates susceptible to the extract. The minimum inhibitory concentration (mg/ml) of the A. paniculata methanol extract ranged from 5 mg/ml to 10 mg/ml while the minimum bactericidal concentration (mg/ml) of the bacteria isolated from diabetic patients ranged from 10 mg/ml to 20 mg/ml. Conclusion: Findings revealed that the methanol leaf extract of A. paniculata very strong antibacterial activity for a wide range of bacteria from blood samples of diabetic patients and more reliable than commercially available antibiotics hence suggesting that leaves of A. paniculata can be used to develop novel antibacterial drugs.

Introduction: Insect-transmitted disease remains a major source of illness and death worldwide. Anopheles stephensi and Anopheles culicifacies are the important vectors of malaria, malaria continues to be a major public health problem in the tropical world. This study is aimed at carrying out repellence activity of Cymbopogon citratus (Lemon grass) extracts on Anopheles mosquitoes using swiss albino rat and human volunteers. Methods: Methanol, chloroform and water were used to extract the bioactive compounds of plant leaves, qualitative and quantitative phytochemical components of plant extracts were determined, twenty-five laboratory-reared 3 day old Anopheles mosquitoes which had been starved for 5 hours were used, extracts and the commercial insecticide N, N-diethyl-3-methylbenzamide (DEET) were applied topically on the skin of uncovered portions of the hand of the human volunteers and abdomen of swiss albino rat after the abdominal hairs has been shaved and the landing rate of mosquitoes were observed to calculate percentage repellency. Results: The result revealed that methanol extract had the highest percentage yield of 10.3%, tannin and alkaloid were present in all extracts. DEET had 100% repellency to Anopheles mosquitoes on both human volunteers and rats for 300 minutes post application, in human volunteers, water, chloroform and methanol extracts, has percentage repellency reduced from 100% to 94% after 60 minutes, 100% to 94% after 120 minutes and 100% to 83% after 150 minutes post application respectively while in swiss albino rat, water, chloroform and methanol extracts, percentage repellency reduce from 100% to 87% after 90 minutes, 100% to 87% 150 minutes and 100% to 90% after 180 minutes post application respectively. Conclusion: Methanol extracts of C. citratus leaves could be used for the development of topical cream that repels mosquitoes for effective control of malaria.

In the Northern Appalachian Basin of the United States, most of the production wells in shale gas reservoirs intersect with a bedded sequence of minable coal layers. The gas wells are often positioned in the coal mine abutment pillars for protection, but longwall-induced stresses may lead to excessive deformation in the gas well casing and potentially leak high-pressure gas to the mining area. Quantitative analyses of the potential gas inflow need an understanding of the rockmass permeability evolution during longwall mining. For this study, a medium-cover (198-m deep) mining site in eastern West Virginia was selected to calculate longwall mining-induced permeability changes. A model in 3DEC numerical modeling code was constructed using the Discrete Fracture Network (DFN) technique to explicitly create fracture systems in the model and calculate fracture apertures under longwall-induced stress and deformations. The calculated fracture apertures are used in a fracture flow code (FFC) to predict the volumetric gas inflow to the mine in the case of a hypothetical breach in a gas well casing. The potential breach location was identified using a 60-arm caliper survey in a test well in abutment pillar, showing that the maximum horizontal displacement occurs 51 m below the surface. The results of FFC simulation for the breach in this location shows that in 100 different DFN realizations, there is no sign of gas reaching the mine workings.
