Introduction. The rapid spread of a new coronavirus infection among populations in many countries worldwide has contributed to the genetic evolution virus, resulting emergence multiple variants SARS-CoV-2 coronavirus. Mutations viral genome can affect ability virus bypass immune system and complicate development diagnostic prophylactic drugs. Data on neutralizing activity sera obtained against ...

The anti-inflammatory action of silver nanoparticles (NPs) has been reported in a murine model of asthma in a previous study. But more specific mechanisms of silver NPs in an attenuation of allergic airway inflammation have not yet been established. Vascular and mucous changes are believed to contribute largely in pathophysiology in asthma. Among various factors related to vascular changes, vas...

BACKGROUND Lung diseases (resulting from air pollution) require a widely accessible method for risk estimation and early diagnosis to ensure proper and responsive treatment. Radiomics-based fractal dimension analysis of X-ray computed tomography attenuation patterns in chest voxels of mice exposed to different air polluting agents was performed to model early stages of disease and establish dif...

It is now possible to quantitate carcinogen adducts on DNA by highly sensitive immunoassays. These techniques are particularly useful for screening human populations for exposure to potential environmental carcinogens. We have developed a panel of monoclonal antibodies that react with benzo(a)pyrene (BP) modified DNA to be used in an enzyme linked immunoassay (ELISA) to quantitate adduct levels...

The ErbB2 oncogene is often overexpressed in breast tumors and associated with poor clinical outcome. p130Cas represents a nodal scaffold protein regulating cell survival, migration, and proliferation in normal and pathological cells. The functional role of p130Cas in ErbB2-dependent breast tumorigenesis was assessed by its silencing in breast cancer cells derived from mouse mammary tumors over...

A lethal cardiotoxic-cytotoxic protein (mol. wt. 6.76 kDa) has been purified from the Indian monocellate cobra (Naja kaouthia) venom by ion-exchange chromatography and HPLC. CD spectra indicated the presence of 23% alpha helix, 19% beta sheets and 35% coil. Complete amino acid sequence was determined by MALDI, which showed similar homology with cardiotoxins/cytotoxins isolated from venom of oth...

Abdominal aortic aneurysms (AAAs) are a major cause of morbidity and mortality in the United States today. We employed a model for AAA development using apolipoprotein E knock out mice fed a high-fat diet and treated with ANG II and β-aminopropionitrile (β-APN) for 4 wk. ANG II induces hypertension and atherosclerotic disease, whereas β-APN inhibits the activity of the lysyl oxidase/ lysyl oxid...

Tolerance to dsDNA is broken in mice with a high-affinity anti-DNA H chain transgene, 56R, on the C57BL/6 background (B6.56R). B6.56R produce more anti-dsDNA Abs than BALBc.56R. To investigate how anti-DNA Abs are regulated on the B6 background, phenotypic and genetic studies were performed. B6.56R have reduced numbers of B cells and phenotypically altered B cell subsets, including relative inc...

This review describes briefly the beneficial use of two vaccines developed by us for treatment of cancers. The vaccine against Luteinizing Hormone Releasing Hormone (LHRH) is effective in carcinoma of prostate as well as in breast cancers dependent on androgens and estrogens respectively. LHRH being identical in both males and females, the same vaccine is usable in both Prostate and Breast ster...
