I) Definitions Bone infarction denotes necrosis of the metaphysis or diaphysis of a long bone, commonly referred to as osteonecrosis. The term may also be applied to some cases involving the epiphysis, but the term avascular necrosis is preferred to describe subchondral osteonecrosis. Other terms used to describe bone infarction are avascular necrosis of bone, … Read more
It is physically possible to lift everything needed for the space settlement from Earth. Even with extremely reusable rockets, this would be extremely expensive. Instead, we can use a fraction of the rockets needed to launch the space settlement and dedicate it for space infrastructure. It will be expensive, but much less so, and there … Read more
Bacilli are the most abundant organism in the rhizosphere and can produce endospores which aid them to survive under adverse conditions. They are Gram positive, aerobic, rod shape, sporulating bacteria that are ubiquitous in nature. Some species have different PGPR capacities (Barriuso and Solano, 2008). There are numerous metabolites that are produced and released by … Read more
CB1 and CB2 receptors are experimentally known to couple with the pertussis toxin-sensitive inhibitory G protein (Gi) (106). The activation of these inhibitory G proteins by CB1 and CB2 agonists leads to the inhibition of adenylate cyclase and the cAMP pathway (107), which ultimately inhibits the activation of cAMP-dependent protein kinase (PKA). This inhibition reduced … Read more
I have long been intrigued by Biology and Forensic Science in particular. I excelled in my Science lessons at school and enjoyed reading science related books. My passion for the subject continued in college and confirmed my desire to study a Forensics related degree at university. I am fascinated in the biological aspects of Forensic … Read more
Abstract: Plants are essential organisms in the environment, using the sun and CO2 to produce oxygen. This is the process of photosynthesis. Plants are producers, meaning they are able to provide themselves with the nutrition they need to thrive. When plants have an abundance of carbon dioxide, they thrive in performing light reactions and the … Read more
All across the globe, infertility is being perceived as a disaster or misfortune that brings consequences related with the society, economy and psychology as well, as reported by WHO (2010). In accordance with the study of Steptoe and Edwards (1978), “Assisted Reproductive Technologies (ARTs)” that covers intra-cytoplasmic sperm injection (ICSI), in vitro mutation (IVM), “pre-implantation … Read more
The Monsoon is a significant contributor to both the economic and social growth of India. Ocean–atmosphere interactions play an important role in the monsoon phenomena thereby making it very much necessary to understand its behaviour. The key role of the Indian Ocean warm pool [sea surface temperature (SST) > 28∘C] in triggering the Indian summer monsoon … Read more
Introduction Imagine, you could go to the clinic and choose on a menu what kind of traits you would like for your child? Green eyes, brown hair, a high IQ and a kind and generous personality? Is this really possible in the future? Can we edit out bad genes that cause diseases in humans and … Read more
A topic that really interests me is human biology and what exists under the skin, the intricate networks of veins and bones all linked together through flesh and muscle. For my personal investigation entitled “SKIN” I aim to explore both what is above and beneath the human skin and experiment with exposing the unseen aspects … Read more
Microbial biofilm are factions of surface-colonized cells encompassed in a matrix of self-secreted extracellular polymeric secretions. Profound application of antibiotics inorder to treat infections due to microbial biofilms has led to the emergence of several strains that exhibit it’s resistance to the drugs. A novel type of 3,6-di(pyridin-2-yl)-1,2,4,5-tetrazine (pytz) capped silver nanoparticle (TzAgNPs) was synthesized … Read more
Ondansetron hydrochloride (OND) is an anti-emetic drug commonly used for management of postoperative and chemotherapeutic-induced nausea and vomiting. It suffers from low absolute bioavailability (60%) and rapid elimination (t1/2; 3-4 h). The current work aimed to develop OND-loaded bilosomes as a promising transdermal delivery system capable of surmount drug limitations. The variables influencing the development … Read more
Abstract In this report, we start by defining key aspects of classical Lagrangian mechanics including the principle of least action and how one can use this to derive the Euler-Lagrange equations. Momentum and Conservation laws shall also be introduced, deriving relations between position, momenta and the Lagrangian of a given system. Following this, we develop … Read more

In this research, Polypropylene (PP) / Ethylene-Propylene Diene Monomer … Read more
1.1 ABOUT MOS KINASE: Mutation in a single cells causes cancer over a period of time in a person’s life. The genes that play a role in causing cancer are: a) tumor suppressor genes b) proto oncogenes Mos is a proto oncogene that is responsible for coding the serine/threonine kinase. In 1980 ,the transforming gene … Read more
