Begum, M.,Hossain, MM,Kim, IH INSTITUTE OF AGRICULTURAL FOOD INFORMATION 2014 VETERINARNI MEDICINA -PRAHA- Vol.59 No.9

<P>This study was aimed at evaluating the effects of different concentrations of the dietary plant extract supplement YGF251 (young growth factor) on growth performance, blood profiles, relative organ weight, nutrient digestibility and meat quality in broiler chickens. A total of 640 one-day-old male Arbor Acres broiler chickens with an average initial body weight of 40.25 &plusmn; 0.5 g were randomly allotted to one of four treatments lasting four weeks with 10 replicates per treatment and 16 chicks per replicate pen. Dietary treatments consisted of: CON (basal diet); YGF0.05 (CON + 0.05% YGF251); YGF0.1 (CON + 0.10% YGF251); YGF0.15 (CON + 0.15% YGF251). There were no statistical differences in body weight (BW), feed intake (FI) and feed conversion rate (FCR) throughout the whole experiment. However, broiler chickens fed with YGF0.1 diets had greater body weight gains (BWG) than chickens fed CON diets during eight to 28 days and zero to 28 days although the means of pH value, breast meat colour, WHC, drip loss, the relative organ weights of liver, spleen, bursa of Fabricius and breast muscle were not affected by any dietary supplementation (P &gt; 0.05). The relative weight of abdominal fat in the CON treatment group was significantly higher than the YGF0.05 and YGF0.1 treatments, although relative gizzard weight was lower with CON treatment compared to YGF0.1 treatment (P &lt; 0.05). Femur length and weight were significantly higher in the YGF251-supplemented chicks than in chicks fed the control diet (P &lt; 0.05). Broiler chickens fed the YGF0.1 diet had significantly higher blood IgG counts compared to chicks fed the CON and YGF0.05 diets (P &lt; 0.05). Moreover, YGF251-supplemented chicks exhibited increased IGF-I concentrations compared to the CON to YGF0.1 treatment (P &lt; 0.05). The results of this study indicate that supplementation with 0.1% YGF251 can increase body weight, IgG and energy digestibility and reduce relative abdominal fat and gizzard weight in broiler chickens, while at all concentrations tested YGF251-supplemented chicks showed higher results for femur length and weight and serum IGF-I concentrations compared to the control treatment in broiler chickens. &nbsp;</P>

Begum, Azeezur Rehman Naseema,Basavaraja, Hadikere Kallappa,Joge, Punjab Govindrai,Palit, Aditya Kumar Korean Society of Sericultural Science 2008 International Journal of Industrial Entomology Vol.16 No.1

Under the all India programme of evaluation of mulberry and silkworm genotypes, twelve bivoltine silkworm breeds obtained from Central Silkworm Germplasm Resource Centre, Hosur (CSGRC) were evaluated at the bivoltine silkworm breeding laboratory, Central Sericultural Research & Training Institute, Mysore (CSR&TI). These breeds were tested during September-October 2003, August-September 2004 and February-March 2005. The average temperature and humidity during September-October 2003 was $26.5^{\circ}C$ and 72.6% RH, while during August-September 2004, it was $26.5^{\circ}C$ and 75.2% RH and during February-March 2005 it was $24^{\circ}C$ and 48% RH respectively. The performance of the breeds in respect of 21 traits was studied and statistically analyzed using analysis of variance (Singh and Choudhary, 1985). Silkworm breeds were short-listed using multiple trait evaluation index method as suggested by Mano et at., (1993). Evaluation Index values were calculated for all the 11 traits of economic importance and six breeds were short-listed based on average index value 50 and above 50. Two breed viz., BV 183 (SMGS-1) have recorded average E.I. >50 in 10 traits (except in neatness) and ranked first and the breed BV 262 (SMGS9) with E.I. value >50 in nine traits except in cocoon weight and neatness ranked second, in the order of merit. These two breeds may be selected as resource material for evolving region specific silkworm breeds.

Begum, Rokeya,Rahman, Mohammad S,Chowdhury, A M Sarwaruddin,Hasan, Choudhury M,Rashid, Mohammad A Kyung Hee Oriental Medicine Research Center 2009 Oriental pharmacy and experimental medicine Vol.9 No.2

The n-hexane and carbon tetrachloride soluble fractions of a methanolic extract of the stem bark of the Couroupita guianensis furnished three compounds, identified as $\beta$-amyrin (1), betulin-$3{\beta}$-caffeate (2) and lupeol-$3{\beta}$-caffeate (3). The structures of the isolated compounds were deduced by extensive spectroscopic analysis as well as by comparison with published values. Compounds 1-3 were subjected to antioxidant screening through free radical scavenging activity by DPPH (1,1-diphenyl-2-picrylhydrazyl), where compound 2 showed moderate antioxidant activity with $IC_{50}$ value $108.0{\mu}g/ml$.

Begum, Vava Mohaideen Hazeena,Mahesh, Ramalingam,Ramesh, Thiyagarajan,Soundararajan, Periasamy Kyung Hee Oriental Medicine Research Center 2008 Oriental pharmacy and experimental medicine Vol.8 No.1

This study was undertaken to evaluate the antioxidant potential of A. lanata on oxalate mediated free radical toxicity in ethylene glycol induced calcium oxalate urolithic rats. Calcium oxalate (CaOX) stone was induced by 0.75% ethylene glycol in drinking water for 28 days. From $29^{th}$ day onwards, the CaOX urolithic rats were treated with A. lanata aqueous suspension (2,000 mg/kg body weight/dose/day) orally for another 28 days. At the end of experimental periods the animals were sacrificed, samples were collected and analyzed the lipid peroxidation product, protein oxidation product, enzymatic and non-enzymatic antioxidants in normal and experimental groups. Lipid peroxidation and protein oxidation products were significantly elevated while enzymatic and non-enzymatic antioxidant levels were significantly decreased in ethylene glycol induced CaOX urolithic rats when compared with control rats. The above alterations were reverted to near control in rats treated with aqueous suspension of A. lanata. This study suggests that A. lanata could prevent the free radical formation from calcium oxalate urolithiasis in rats and protecting the renal cells from oxidative injury.

Evaluation of Information Technology Impact on State-owned Commercial Banks' Efficiency: The Case of Bangladesh

BEGUM, Shakera,BATEN, Md. Azizul,ALI, Rahmat Korea Distribution Science Association 2022 Asian journal of business environment Vol.12 No.1

Purpose: This study measures the effect of Information Technology (IT) on both cost and profit efficiency of State-owned Commercial Banks (SOCBs) in Bangladesh. Research design, data and methodology: Yearly Non-IT and IT data are collected from the annual report of SOCBs of Bangladesh from 2008 to 2017. Variable Return to Scale (VRS) cost Data Envelopment Analysis (DEA) and Profit DEA are employed to measure the efficiency of SOCBs and Ordinary Least Square (OLS) is used to investigate the impacts of ICT components on operating cost and profit efficiency for SOCBs. Results: The average cost efficiency (74.4%) was noticed higher than the average profit efficiency (20.6%) for SOCBs. SOCBs were more affordable and less profitable for both cost and profit efficiency. Rupali bank was the most cost efficient while Sonali bank was the most profit efficient. IT Investment and IT personnel expenses were positively significant for cost efficiency. IT income, IT personnel, IT personnel expenses, ATM expenses, and Credit card expenses were negatively significant for profit efficiency. Conclusion: The further studies can combine DEA with machine learning algorithms to study the impact of IT on banks' performances. The results could aid government to remove the hindrance of progress in Bangladesh.

Initiating Smokeless Tobacco Use across Reproductive Stages

Begum, Shahina,Schensul, Jean J.,Nair, Saritha,Donta, Balaiah Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17

Background: The use of smokeless tobacco (SLT) among women is increasing in India, especially among those with limited education and resources. Preventing the initiation of SLT among women is critical since it has known negative consequences for oral and reproductive health. Most research on tobacco initiation in India focuses on adolescents. This paper addresses the unrecognized issues of post marital initiation among women of reproductive age, highlighting the importance of reproductive stages in women's tobacco initiation. The objective is to examine the correlates of SLT initiation among low income women in Mumbai from pre-marriage through early marriage, first pregnancy and beyond, using case examples to illustrate initiation during each of these stages. Materials and Methods: In 2011-2012, cross-sectional community level survey data were collected from a representative sample of 409 daily SLT-using married women aged 18-40 years in a low income community in Mumbai. Information on socio-demographics, initiation by reproductive stage, types of tobacco use, childhood exposure to tobacco, learning to use, and initiation influences and reasons were collected through a researcher-administered survey. Univariate and bivariate analysis assessed factors influencing initiation of SLT use by reproductive stage. In addition 42 narratives of tobacco use were collected from a purposive sample of pregnant and non-pregnant married women addressing the same questions in detail. Narratives were transcribed, translated, and coded for key concepts including initiation of tobacco use. Results: Thirty-two percent of women initiated SLT use before marriage, 44% initiated after marriage but before pregnancy, 18.1% initiated during their first pregnancy and the remainder started after their first pregnancy. Mean age of marriage among women in this study was 16 years. Younger women (i.e. age at time of the interview of less than 30 years) were 0.47 [95% CI (0.32, 0.87)] percent less likely to initiate after marriage than women aged more than 30 years. Women who got married before 18 years of age were 2.34 [95% CI (1.40, 3.93)] times more likely to initiate after marriage than their counterparts. Childhood exposure was a predictor for initiating SLT use prior to marriage but not after. Women reporting tooth and gum pain were 1.85 times more likely to initiate after marriage than their counterparts. Husband and neighbours were the most significant influences on post-marital initiation. Narratives highlighted differences in processes of initiation pre and post marriage and during pregnancy. Conclusions: Most tobacco prevention interventions are directed to adolescents in school. This study suggests that especially for low literate or illiterate women, school based interventions are ineffective. To be effective strategies to prevent SLT initiation must reach women in urban areas at or immediately after marriage and during their first pregnancy. Messages must negate culturally rooted beliefs about the health benefits of SLT in order to prevent initiation and onset of daily use.

Electrodeposited Palladium Nanotubes on Nanoclusters Mosaic Basement for Electrooxidation of Hydrazine

Begum, Halima,Ahmed, Mohammad Shamsuddin,Jeon, Seungwon American Scientific Publishers 2017 Journal of Nanoscience and Nanotechnology Vol.17 No.7

<P>A series of electrochemically deposited palladium nanotubes (e-PdNTs) on nanoclusters (e-PdNCs) mosaic basement have been prepared with variation of cycle number and scan rate through a facile electrochemical deposition method using cyclic voltammetry (CV) technique in 20 mM HCl solution and have been used as an anode electrocatalyst for hydrazine (N2H4) oxidation reaction. The morphology and structure of the self-formed e-PdNTs catalysts have characterized by scanning electron microscopy. As observed, the size and amount of e-PdNTs increased with the increasing of cycle number and decreased with respect to the increasing of scan rate. The overall experimental parameters have determined that the superior and direct electrocatalytic N2H4 oxidation obtained with lowering NH3 formation upon 6 cycles deposited e-PdNTs at 50 mV s(-1) scan rate in 0.1 M KOH solution than that of other prepared e-PdNTs and Pd/C in respect to the onset potential, current intensity and durability. The lower detection limit (3.6 mu M) and the linear range of N2H4 (up to 14 mM) have also been determined on e-PdNTs via amperometry for further sensor application.</P>

Begum, Mumtaz,Karim, Sajjad,Malik, Arif,Khurshid, Rukhshan,Asif, Muhammad,Salim, Asmat,Nagra, Saeed Ahmed,Zaheer, Ahmad,Iqbal, Zafar,Abuzenadah, Adel Mohammed,Alqahtani, Mohammed Hussain,Rasool, Mahmo Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

Background: High incidence of breast cancer and its fatal effect has reached an alarming stage across the globe, including the third world countries. Many factors have been reported to be associated with the development of breast cancer but detailed structural and functional information is missing. CA 15-3 is one of the known potential tumor marker of breast cancer; however little is known about structure and functional site of this protein. Present study aims to investigate the functional role of CA 15-3 in breast cancer, especially in development and metastasis. Material and Methods: Hundred female breast cancer patients confirmed by histopathological reports were included in the study. Their physiological characters were recorded in a performa. Enzyme linked immunosorbent assay (ELISA) technique was used to estimate serum CA 15-3 level. Immunohistochemistry was done for estrogen (ER), progesterone (PR) and Her2/neu receptors expression. Results: The study revealed the details of physiological characteristics of female breast cancer. Mean age was $37.72{\pm}5.99$ and $55.05{\pm}7.28$ years and serum CA 15-3 (MUC1) level was $60.47{\pm}8.59$ and $63.17{\pm}4.58$ U/ml in pre and post-menopause respectively, and both groups of women had sedentary life style. Their receptor status especially of progesterone, estrogen and HER-2/neu were positive in 50% of premenopausal women and 65% of postmenopausal women. Conclusion: There are multiple physiological factors promoting breast cancer. High serum CA 15-3 level and hormonal imbalance of ER, PR and Her2/neu appears to be the main cause of breast cancer. It may be possible that the functional sites of these proteins may be altered which may increase the chances of metastasis in breast cancer.

Begum Akuzum,김시내,Tam Thanh Nguyen,홍재우,이시영,김은혜,김주희,최여옥,전현정,이영민,김현우,손동현,김수현 대한면역학회 2018 Immune Network Vol.18 No.3

Virus-like particles (VLPs) derived from human papillomavirus (HPV) L1 capsid proteins were used for HPV quadrivalent recombinant vaccine. The HPV quadrivalent vaccine is administrated in a 3-dose regimen of initial injection followed by subsequent doses at 2 and 6 months to prevent cervical cancer, vulvar, and vaginal cancers. The type 6, 11, 16, or 18 of HPV infection is associated with precancerous lesions and genital warts in adolescents and young women. The HPV vaccine is composed of viral L1 capsid proteins are produced in eukaryotic expression systems and purified in the form of VLPs. Four different the L1 protein of 3 different subtypes of HPV: HPV11, HPV16, and HPV18 were expressed in Escherichia coli divided into 2 fragments as N- and C-terminal of each protein in order to examine the efficacy of HPV vaccine. Vaccinated sera failed to recognize N-terminal L1 HPV type 16 and type 18 by western blot while they detected N-terminal L1 protein of HPV type 11. Moreover, the recombinant C-terminal L1 proteins of type 16 was non-specifically recognized by the secondary antibody conjugated with horseradish peroxidase. This expression and purification system may provide simple method to obtain robust recombinant L1 protein of HPV subtypes to improve biochemical analysis of antigens with immunized sera.
