Biochemical, Antimicrobial Characterization of Dooars Tea (Camellia sinensis) Clone during CTC Manufacturing
Abstract: Industrial manufacturing of CTC tea includes different stages. The polyphenol content catechins are oxidized from stage 1–4 (including withering, cutting/tearing, fermentation/oxidation and drying processes). The catechins are polymerized to tannins with the help of enzyme polyphenol oxidase (PPO), both classes of compounds show differential antioxidant (total flavonoid content, UV absorbing compounds content, antioxidant enzyme Phenylalanine ammonia lyase activity is changed), antimicrobial and therapeutic potentials, usually reduced in late (dried) stages. …

Impact of PPAR-γ2 pro12Ala Gene Polymorphism and Susceptibility of Type 2 Diabetes Mellitus in Patients Visiting Gondar University Teaching Hospital
Abstract: Type 2 diabetes mellitus (T2DM) is characterized by hyperglycemia that can occur through mechanisms such as; impaired insulin secretion, insulin resistance in peripheral tissues and increased glucose output by liver. Type 2 diabetes clearly represents a multifactorial disease, and several findings indicate that multiple genetic and environmental factors are important contributing factor involved in the pathogenesis of this disease. Recently great emphasis has been given to genetical factors to combat …

Comparison of the Keratinase Gene Sequences of Fast, Slow and Intermediate Feather Degrading Strains of Bacillus licheniformis
Abstract: Feathers are composed of beta keratin which is an insoluble protein resistant to degradation. Bacillus licheniformis has a gene that codes for a keratinase enzyme that hydrolyzes feathers. The DNA sequences of the genes coding for keratinase enzymes of various strains of B. licheniformis were compared. Some strains of the bacteria hydrolyze feathers rapidly, some slowly, and some at an intermediate rate. The mature keratinase enzyme is composed of 274 …

Potentiality of Bacteriocins as the Attachment Inhibitors of HIV-1 gp120
Abstract: It is postulated that some bacteriocin derivatives are consummate candidates to inhibit the binding of HIV gp120 to CD4 T-cell. From the discovery of bacteriocin compounds in 1925 and forth, nearly 300 bacteriocins have been identified. Of various bacteriocins, there are some which have been used successfully for inhibiting both animal and human pathogens. Unfortunately, no large extent research has been found in the development of various bacteriocins as HIV …

Antimicrobial, Antioxidant Evaluation of Majestic Darjeeling Green and Black Tea during Storage
Abstract: Three months storage in ambient temperature and humidity causes the changes in biochemical (antioxidant) and antimicrobial properties of Darjeeling green and black tea. Having higher extent of total polyphenol and non-enzymatic antioxidant flavonoid content green teas are able to show higher antioxidant and antimicrobial activities against different microorganisms. Due to manufacturing procedures (greater extent of fermentation) some of the enzyme activities (including antioxidant enzyme catalase, phenylalanine ammonia lyase) are lowered …

Assessment of the effectiveness of PMTCT (Prevention of Mother to Child Transmission) to Children Born from HIV-1 positive Mothers
Abstract: Mother-to child transmission (MTCT) of HIV is one of the biggest challenges of the HIV/AIDS pandemic especially in resource constrained settings. Africa has the highest burden of the disease accounting for about 90% of pediatric HIV infections. Approximately 370,000 children became infected with HIV globally; most of these infections occurred through mother-to-child transmission. PMTCT (prevention of mother to child transmission) service reduces the risk of this transmission. In the absence …

Methicillin Resistant Staphylococcus Aureus (MRSA) and Its Different Testing Methods: A Review
Abstract: Staphylococcus aureus, a gram-positive bacterium is a serious current health care concern. In the mid-1980s, S. aureus strains emerged that were resistant to the beta-lactamase-stable penicillin, these strains were termed methicillin resistant S. aureus (MRSA). Methicillin resistance in S. aureus is primarily mediated by the mecA gene, which codes for the modified penicillin-binding protein 2a. MRSA strain has become one of the well-known etiologic agents for a wide variety of …
