background and objective: neisseria meningitidis is a leading cause of meningitis and sepsis worldwide. the factor h binding protein (fhbp) is a key virulence factor of neisseria meningitidis that is able to selectively bind to human factor h, the key regulator of the alternative complement pathway, which it has important implications for meningococcal pathogene- sis and vaccine design. the aim...

Background: Male infertility has many causes, including genetic infertility. The NOP2/Sun domain family, member7 (Nsun7) gene, which encodes putative methyltransferase Nsun7, has a role in sperm motility. The aim of the present study was to investigate the effect of the T26248G polymorphism on Nsun7 protein function and its role in male infertility. Materials and Methods: Semen samples were col...

SARS-CoV-2 remains life-threatening human pathogen witnessed in the present world. Purpose. The key objective of this research was to incorporate a bioinformatics technique forecast molecular docking ACE2-associated SARS-CoVs nucleocapsid protein. Methods. Different tools were used study order compare chemical structures with their biological behaviour at levels atoms and ligand-binding affinit...

The SARS-CoV-2 Omicron variant has spread rapidly and is considered the predominant in world, its main characteristic related to evade immunity from natural infection or vaccines, due multiple mutations spike protein. On other hand, medicinal plants have been used as alternatives therapies ameliorate some signs symptoms COVID-19, our previous work, cat’s claw (Uncaria tomentosa) stem bark studi...

objective(s): a fast and reliable evaluation of the binding energy from a single conformation of a molecular complex is an important practical task. artificial neural networks (anns) are strong tools for predicting nonlinear functions which are used in this paper to predict binding energy. we proposed a structure that obtains binding energy using physicochemical molecular descriptions of the se...

Human serum albumin (HSA) is an abundant, multifunctional and nonglycosylated negatively charged plasma protein. HSA ascribed ligand-binding and transport properties, antioxidant functions and enzymatic activities. In the present study, the interaction and side effects of a new designed anti-cancer compound (1,10-phenanthroline butyl dithiocarbamato palladium(II) nitrate) on HSA have been inves...

Coronaviruses such as SARS-CoV-2, which is responsible for COVID-19, depend on virus spike protein binding to host cell receptors cause infection. The SARS-CoV-2 binds primarily ACE2 target cells and then processed by membrane proteases, including TMPRSS2, leading viral internalisation or fusion with the plasma membrane. It has been suggested, however, that other than may be involved in binding...

Bisphenol A (BPA) is one of the most widely used chemicals in the plastic industry, which enter the human body through occupational and food contact. In this study, the protein changes in rat cerebral cortex was evaluate in order to evaluate the neurotoxicity of BPA. 24 adult male rats were randomly selected and divided into four groups (n=6) and each group respectively received 0, 0.5, 5 and 5...
