The Purpose of this study is to measure the impact of capital adequacy ratio i.e., core capital ratio, supplementary capital ratio, and total capital fund ratio; financial performance i.e., return on assets and return on equity as well as their relationship. It has also focused on effect of capital adequacy ratio on financial performance of commercial banks in Nepal. Descriptive and casual comparative research design has been used in this study. It is based on secondary sources of data. The data were collected from annual audit report of twenty-six commercial banks from fiscal year 2012/13 to 2018/19 out of twenty-seven. Rastriya Banijya Bank has been excluded in this study due to the unavailability of annual audit report. Total number of observations were 182. The mean range, standard deviation, coefficient of variation, correlation analysis, and regression analysis statistical tools were used in this study. This study reveals that the return on equity is highly scattered in comparison to return on equity. Supplementary capital is highly spread in comparison to core capital ratio. There is low degree of positive relationship of return on assets with core capital ratio and supplementary capital ratio. There is low degree of positive relationship of return on equity and supplementary capital however low degree of inverse relationship in between return on equity and core capital. Core capital ratio and total capital fund ratio positively influence on return on assets and return on equity.

Objective: The main objective is to isolate Lactic acid bacteria from traditional fermented food of Kathmandu valley and to study their antimicrobial properties by agar well diffusion method. Methods: A total of 30 samples of 4 different types of traditional fermented food (Gundruk and sinki, Pickles and Dahi) were obtained from Kathmandu valley and processed in Microbiology Laboratory of Padma Kanya Multiple Campus. For identification of Lactic acid bacteria (LAB), Gram staining, catalase and motile tests were done. In the carbohydrate fermentation test, all isolates were processed for fermentation of glucose, lactose, sucrose and fructose. Bacteriocin was extracted by precipitation method. Antibiotic susceptibility of the isolates was determined by using modified Kirby-Bauer disc diffusion method. The antimicrobial activity of Lactic acid bacterial (LAB) was done by agar well diffusion method. Results: A total of 21 LAB isolates were identified which were 10 Lactobacillus spp (47.6%), 8 Pediococcus spp (38.0%) and 3 Streptococcus spp (14.3%). The antimicrobial activity of bacteriocin showed inhibitory activity against Shigella spp, Escherichia coli and Bacillus spp but did not show inhibition to Staphylococcus aureus, Salmonella spp. and Klebsiella pneumoniae. For the quality control, the antimicrobial activity of bacteriocin was done on ATCC (25923) Staphylococcus aureus. All isolates were susceptible to ampicillin while resistant to nalidixic acid and Co-trimoxazole. Conclusion: The present study showed the bacteriocin produced by LAB from traditional fermented food (Gundruk and Sinki, yogurt and Pickle) showed antimicrobial activity against different bacteria which underline its important role in improving food quality and increasing safety.

The major intend of this study is to investigate the volatility clustering in NEPSE index. To reach the conclusion, 3392 annually observed time series data from 1 June 2006 to 7 April 2021 were obtained from various volume of annual trading report of Nepal Stock Exchange (NEPSE) and website of NEPSE and symmetric Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models––GARCH (1,1), GARCH-M (1,1) and asymmetric GARCH family models––TGARCH (1,1), EGARCH (1,1), and PGARCH (1,1) were employed. The stylized facts confirm that the volatility clustering and leverage effect on the return of NEPSE index are existed. The empirical analysis reveals that the positive correlation between volatility and the expected return of NEPSE index in terms of risk premium and then conditional variance process is persistent. The empirical results also show that the symmetric model is better fitted to full sampled period and asymmetric GARCH family models to before-and after-earthquake sampled period. This study covers the larger dataset which is divided into different episodes with different economic condition of Nepal and thus, it is assumed to be a purely an initial work on Nepalese stock exchange.

Elderly is the vulnerable age; and their health status and well-being is an important area of concern which is reflected by Quality of Life (QOL). With the increasing population of the aged in developed as well as developing world, proportion of elderly living in old age homes is also in increasing trend due to migration of children and nuclear family concept. The objective of the study waste assesses the QOL of the elderly people residing in old age homes at Biratnagar with the use of WHOQOL-BREF questionnaire. Cross-sectional descriptive study including the census of the elderly living at selected old age homes was used. Data was collected from the 57 elderly meeting the inclusion criteria through face to face interview by using interview guide. The findings of the study showed that the participants were of age group from 60 and above, and 66.70%of them were female. Among 57 respondents, 42 (76.39%) were married and 15(23.61%) were unmarried. Of those married, nearly half of them (47.61%) had no children. More than 1/3 rd (71.92%) of the respondents were illiterate and nearly half (45.61%) of them were involved in agriculture in the past. As perceived by the elderly themselves, the overall quality of life was found to be good in less than half (42.10%) and overall quality of health score was found to be satisfied in more than half (59.64%) of them. Also, the study has revealed higher score in physical domain and psychological domain which reflects that the components of these domains as physical needs, health needs, religious and spiritual needs, financial needs have been addressed. Thus, it can be concluded that quality of life is perceived good by less than half and quality of health is perceived satisfactory by more than half with higher score in physical and psychological domain. However, they are in need of social support and relationship which can be promoted to some extent by inculcating the content of geriatric care in school curriculum. Also, there should be provision of visit to geriatric centers so that awareness regarding this area could be raised.

Objectives: To determine the prevalence of Gram-negative bacteria in lower respiratory tract infections and study the biofilm producing Pseudomonas aeruginosa. Methods: This study was conducted at B & B Hospital Pvt. Ltd., Lalitpur, Nepal from February to September 2018. The samples were collected from the patients (n=420) with signs and symptoms suggestive of LRTIs. The isolated organisms were identified and antimicrobial sensitivity was performed. Among all the isolates, P. aeruginosa isolates were subjected for biofilm detection by microtitre plate method. Results: Out of 420 specimens, 90 (21.6%) were culture positive. Klebsiella pneumoniae (42.9%) was found to be the predominant organism with higher rate of resistance to antibiotics. A total of 25 isolates of P. aeruginosa were isolated among which 15 (60%) were biofilm producers. Biofilm-producing isolates of P. aeruginosa were found more resistant to the tested antibiotics. Conclusion: Gram-negative bacteria were found to be the predominant etiological agents in causing the LRTIs; K. pneumoniae, being the most commonly isolated bacteria. Most P. aeruginosa were capable of producing the biofilm. The biofilm producers were more resistant to the antibiotics. The biofilm may help increase the resistivity nature of the bacteria.

Objectives: To determine anti-biofilm effect of fresh garlic extract (FGE) on Staphylococcus aureus biofilm production and the relationship between methicillin resistance and biofilm production intensity. Methods: Clinical S. aureus isolates were identified methicillin resistant S. aureus (MRSA) by cefoxitin disc diffusion method. The anti-biofilm effects of FGE on S. aureus biofilm biomass determination was done using crystal violet assay. Results: Among 71 S. aureus isolates, MRSA were 37 (52.1%). Among biofilm producers, comparison of biofilm biomass (absorbance at 492 nm) showed no significant differences in biofilm formation ability between MRSA and MSSA (p=0.325). Use of 10% FGE decreased biofilm production in MRSA and MSSA by 40.4% (p<0.001) and 48.1% (p<0.001) respectively. Detachment assay using sodium dodecyl sulfate showed that control group biofilm biomass was decreased by 41.2%, while test group was decreased by 61.7% (p<0.001). Conclusion: Garlic extracts has potency as an anti-biofilm agent and could be developed and used to manage different S. aureus biofilm related infections.

Objective: Antibiotic toxicity and multi drug resistant pathogens are the two greatest challenges that today's medical world has been facing. As a consequence of the haphazard use of antimicrobials, the spread of antimicrobial resistance is now a global issue. This study aimed to investigate antimicrobial activity of some common spices. Methods: During the study period Five commonly used spices were collected from local market of Lagankhel, Lalitpur. The antimicrobial activity of selected naturally grown spices was done against two gram positive and three gram-negative pathogenic bacteria. The extracts of the spices were obtained by using absolute ethanol (99.9%) to carry out the antibacterial susceptibility assay using agar well diffusion method. Results: The result of agar well diffusion method showed Clove and Cinnamon were found to possess relatively higher antimicrobial activities by preventing the growth of all 5 tested bacteria. Gram positive bacteria were found to be more sensitive to spices than Gram negative bacteria. Conclusion: The finding of this study showed that extract of spices can be alternative to synthetic drugs to control infectious diseases.
