A total of 50 isolates were included in this study and 28 different antibiotics were used to determine the antibiotic susceptibility of isolates. The pure colonies of <em>K. pneumoniae </em>were isolated by conventional method of bacterial identification and then the pure bacterial growths were tested for antibiotic susceptibility against different antibiotics. PCR amplification was performed to identify three virulent genes; <em>Klebsiella</em><em> pneumoniae</em> Carbapenamase (KPC), Metallo-β-lactamases (NDM), Imipenamase (IMP) followed by sequencing analysis. The <em>K. pneumoniae </em>isolates were found highly resistant to Ampicillin by 56% and Amoxicillin, Cefepime, Cefixime, Cefaclor, and Cefuroxime by 54%. The isolates were highly sensitive to Colistin (100%), Amikacin (14%), Imipenem and Meropenem (18%). The prevalence of antibiotic resistance was found more in female patients as compared to males. The prevalence of NDM gene was 22% while we were unable to detect KPC and IMP in these isolates. In the present study, a prominent correlation was found between the presence of NDM gene and antibiotic resistance as this gene was found positive only in MDR strains. The co-existence of multiple drug resistance and the NDM gene is an alarming situation and demand more research to determine possible mechanism of co-existence between blaNDM and antibiotic resistance.</p> 2019-09-24T09:50:26-04:00 ##submission.copyrightStatement## Matricaria Chamomile Protective Effect Against Type-2 Diabetes Mellitus and Cancer Cell Linings 2019-09-25T09:18:16-04:00 Shahnai Basharat Syed Amir Gilani Faiza Iftikhar Muhammad Mustafa Qamar Mian Anjum Murtaza Sanabil Anmol Amna Imtiaz Sammana Ghazanfer Ameer Hamza Affifa Rajpoot <p><em>Matricaria Chamomilla</em> is one of the most popular old times herbal medicine which is known to mankind.

Saleem Muhammad Naveed <p>Germin like proteins (GLPs) is a heterogeneous group of proteins that are part of Cupin superfamily. Various GLPs of Grapevine (VvGLP3) have been identified and characterized at molecular but not at the structural level. This study analyzes the structure of VvGLP3 to elucidate its role in defense against powdery mildew disease caused by <em>Erysiphe necator</em>. Physiochemical analysis through the high aliphatic index (AI), low instability index and grand average of hydropathy (GRAVY) reveal that VvGLP3 is heat stable hydrophobic protein. InterProScan was used to check the similarity of VvGLP3 to other GLPs and TMHMM indicates that VvGLP3 is a transmembrane protein. Secondary structure of VvGLP3 reveals that it consists of random coils followed by extended α-helix and β-trends and I-TASSER was employed to construct a 3-D structure of VvGLP3. A molecular docking approach was applied to study molecular interaction and binding pattern by Auto Dock Vina. I-TASSER and SOPMA were used to determine the functionally important residues and their role. In the present study, molecular docking binding affinity energy is from -1.5 to -1.3 of germin like protein with manganese (Mn<sup>+2</sup>) co-factor which depict its role in defense against powdery mildew disease.</p> 2019-09-24T09:46:20-04:00 ##submission.copyrightStatement## Isolation and partial characterization of antimicrobial proteins /peptides from Moringa oleifera 2019-09-24T09:59:24-04:00 Anum Shakir Sadaf Riaz Muhammad Afzal, Mr. Basit Zeshan Salma Batool <p><strong><em>Moringa oleifera</em></strong> is worldwide distributed plant because of its number of pharmacological and nutritional benefits. In this study, protein extracts of <strong><em>M. oleifera</em></strong> leaves and flowers were prepared. Extracts were purified by dialysis and quality of the sample was assessed through SDS-PAGE. Antimicrobial and antioxidant activity of these extracts was determined by using of disk diffusion method, Dpph (free radical scavenging assay) and enzymatic assay. The antimicrobial activity of <em>M. oleifera</em> protein extract of flowers and leaves were determined against multidrug – resistant bacteria e.g Methicillin-resistant <strong><em>Staphylococcus aureus</em> (MRSA)</strong>, <strong><em>Escherichia coli</em></strong> and <strong><em>Salmonella typhi</em></strong>. Extract results showed the maximum zone of inhibition against <strong>MRSA</strong> and minimum zone of inhibition against <strong><em>E. coli</em> </strong>and<strong> <em>S. typhi</em></strong> whereas protein extract of leaves did not show any antibacterial activity against these bacteria. MIC of flower extract was determined as 166ug/ml against <strong>MRSA </strong>whereas <strong><em>E. coli</em> </strong>and<strong> <em>S. typhi</em></strong> was recorded as 500ug/ml. enzymatic activity (peroxidase) result showed that leaf and flower protein extract possess higher enzymatic activity at time of 10 minutes and lower at time of 20 and 30 minutes. Protein extract of leaf showed higher scavenging activity at time of 40and 60 and lower at time of 20 whereas flower protein extract showed higher scavenging activity at time of 60 min and lower at time of 40 and 20.

It is bullet shaped virus with small RNA genome that encode five proteins that are responsible for the pathogenicity. G protein have main role in pathogenicity. It attack the central nervous system by using network of nerves cells, hijack it and starts transcribing itself. There is no cure for rabies but it will be avert by preventive measures. The vaccination of dogs are first step to prevent rabies virus.&nbsp;</p> 2019-05-05T02:28:12-04:00 ##submission.copyrightStatement## Impact of school-based nutrition education intervention on consumption of fruits and vegetables among middle school children (age 7-10 years) 2019-05-17T16:02:05-04:00 Faiza Iftikhar Amina Chughtai, Ms. Sanaullah Iqbal, Dr. Sajid Khan Tahir, Dr. <p>To evaluate the impact of school-based nutrition education intervention on the consumption of fruits and vegetables (FV) among middle school children. It was a quantitative study. One-eighty students were selected via purposive sampling and divided into two groups, control (G1= 90) and intervention group (G2=90). The intervention consisted of nutrition education lectures related to the importance, benefits, and consumption of fruits and vegetables. The data collection instruments included knowledge, attitude, and practices (KAP) questionnaire and food frequency questionnaire (FFQ). Subjects were measured at baseline and at 2 months post-treatment. <strong>&nbsp;</strong>Before the intervention, no significant difference was observed between the intervention and control group regarding knowledge, attitude and practices related to fruits and vegetable consumption (P&gt;0.05). However, after the educational intervention, the mean score of knowledge (14.20±2.07), attitude (5.38±0.99) and practices (17.6±2.48) related to fruits and vegetables consumption were significantly higher in the intervention group when compared to the control group (P&gt;0.05). Consumption of fewer fruits and vegetables included: banana (87.8%), apple (82.2%), mango (77.8%), cucumber (63.3%), vegetable salad (55.6%) and potato (86.7%) were increased in the intervention group after nutrition education intervention. School-based nutrition education intervention on the consumption of fruits and vegetables is most likely to be effective to increase nutrition knowledge and modify attitude and practices of children related to fruits and vegetable consumption. Future researches should be conducted on school-based interventions with longer intervention periods and higher sustainability.</p> 2019-05-05T02:17:35-04:00 ##submission.copyrightStatement##
