We presented a nonlinear time-fractional model of Hepatitis B in order to understand the ‎outbreaks of this epidemic disease. The fractional parameter is used to develop the system of ‎complex nonlinear differential equations by using Caputo sense with fractional order ‎derivative. We investigated the qualitative analysis of the fractional-order model and also the ‎stability of the model was checked through the analysis. Hepatitis B is a highly contagious ‎disease that can sp

In this study, a general, efficient, and simple methodology for biocatalytic reduction of carbonyl ‎compounds such as acetophenone 1a and 4-chloroacetophenone 2a using freshly cut ripen fruit of fresh ‎pumpkin in the aqueous medium at room temperature was reported. The prochiral ketones can be ‎reduced to chiral secondary alcohols in a generalized way. The obtained results indicated that the ‎pumpkin fruits could be used as biochemical catalysts to contribute to the preparation o

Background: Studies on bilingualism and cognitive development are specifically invaluable among children with an intention to improve their future performance. Considerable evidence suggests that bilinguals are more capable of controlling their attention compared to monolinguals. Yet, these studies do not focus on specific populations such as children suffering from Attention Deficiency and Hyperactivity Disorder (ADHD). This study intended to evaluate the efficacy of English language teaching,

The infection of HIV causes AIDS, which is a prevalent problem today. Retroviral infection happens upon the integration of a copy of the DNA of the viral genome into the host DNA at any location in the genome but is preferred in certain regions of the chromatin as a necessary step in the replication. The challenge in the treatment of retroviral infections is that the integrated viral DNA is sustainably maintained and replicated along with cellular DNA through the cell division. Although wide pro

Lectins are a divergent group of carbohydrate-binding proteins of non-immune origin that are widely spread in all kingdoms of life. Several postulations have been put forward to describe the physiological obscure functions of plant lectins. Functions such as storage proteins, defensive role against predators or as endogenous enzyme stabilizer were suggested. This work was undertaken to enable further investigation on the possible role of plant lectins. Dry good quality seeds of Erythrina Abyssin

Background: There are so many studies with controversial results focusing on pregnancy outcomes in adolescents. Gynecologic age (GA)- the time between menarche and chronological age at the first pregnancy- has been considered as a physiological maturity indicator with a lower GA assumed as a risk factor for pregnancy outcomes in adolescents. The present study aimed to investigate the relationship between GA and maternal/fetal weight gain in adolescent pregnancies. Methods: This is an analytical

Rheumatoid arthritis (RA) is a chronic inflammatory joint disease. Vitamin D has been postulated to have a role in autoimmune diseases. The aim of this study was to answer, “whether treatment with vitamin D can improve RA patient outcome”. Forty female patients with rheumatoid arthritis with the age of 49.38±13.11 years, and forty healthy females as control with age of 45.14±12.63 years were included in the study. Patients were given a dose of 50,000 IU/week of vitamin

Maltase is one of the key enzymes in our digestive processes, as it is the main salivary enzyme in the digestion of carbohydrates in the mouth. The present investigation aimed to evaluate the impact of some additive materials on maltase activity, and the role of immobilization of the enzyme on chitin in improving its characters. After different purification steps, the recorded specific activity of maltase from Cucurbita pepo L. was 385 units mg-1 protein and the fold was 4.4. Addition of EDTA, 0
