We employed the suppressive subtractive hybridization to identify 41 up- and downregulated transcripts in Jurkat cells after benzo[a]pyrene (BaP) treatment. Among the 21 downregulated transcripts, we found that BaP suppresses the Keap1 transcript by 7.5-fold. Subsequent analyses revealed that BaP significantly suppresses the Keap1 message and protein levels to about 40 and 60%, respectively, of...

OBJECTIVE The prediction of health impairment due to work overload is subjectively assessed based on recognized symptoms; however, objective evaluation is primarily ideal in the field of occupational health. Recently, some biomarkers of autonomic function and/or oxidative stress were reported to be associated with fatigue. This study aimed to preliminarily investigate whether these biomarkers c...

An efficient in-vitro micropropagation protocol has been developed for Berberis chitria (Lindl.) - a rare medicinal plant from Himachal Pradesh, India using seeds and nodal explants. The effects of different concentrations BAP GA3 seed germination was investigated consequently 6.0 mg/l + 0.0 reported to be excellent germination. Callus induction leaf explants aseptically grown seedling were als...

An in vitro regeneration protocol has been standardized via direct and indirect methods from excised root explants of C. bonduc, a threatened woody legume used for the treatment of contagious diseases, inflammation, leprosy, antiperiodic, febrifuge, anthelmenthic, urinary disorders, leucorrhoea, piles and to heal wounds. MS medium supplemented with 17.75 micromol BAP and 2.46 micromol IBA, indu...

Alzheimer’s disease (AD) is a multifactorial disease in which b-amyloid peptide (bAP) plays a critical role. We report here that the soluble fraction 1–40 of bAP differentially degrades protein kinase C-a and -g (PKCa and PKCg) isoenzymes in normal (age-matched controls, AC) and AD fibroblasts most likely through proteolytic cascades. Treatment with nanomolar concentrations of bAP(1–40) induced...

A modern biotechnological technique to obtain useful natural products from plants is to isolate them from their callus cultures. Lallemantia iberica is an annual herb of the Lamiaceae family known for its stimulant, diuretic, and expectorant effects in Iranian folk medicine. The present study investigated the induction of plant callus tissue and identification of its volatile compounds. For thi...
