Botulinum Toxin (BT) is a natural molecule produced during growth and autolysis of bacterium called Clostridium botulinum. Use of BT for cosmetic purposes has gained popularity over past two decades, and recently, other therapeutic uses of BT has been extensively studied. BT is considered as a minimally invasive agent that can be used in the treatment of various orofacial disorders and improvin...

The effects of the human and bovine LSF (derived from sera) as well as their purified fractions were studied on murine lymphocytes reactions indicated by blast transformation (BT) assay, mixed lymphocyte culture (MLC) and IgG synthesis. The results indicated that bovine lipid suppressor factor (LSF) has significant immunosuppressive activity on lymphocytes proliferation both in BT and MLC ...

In India, the area under transgenic crop cultivation has witnessed a phenomenal growth from 1.3 million hectares in 2005 to 3.8 million hectares in 2006, which is an increase of about 300 % in a year period (James 2006). Till March 2005, a total of 20 Bt-transgenic cotton hybrids have been released for commercial cultivation in northern, western and southern regions of India (Sharma et al. 2006...

Collards (Brassica oleracea var. acephala) are an important vegetable crucifer produced worldwide for human consumption, and one subject to severe injury by Lepidoptera. We have produced Bacillus thuringiensis (Bt)-transgenic collard lines that have the potential to be used either for direct control or as a ‘‘dead end’’ trap crop for Lepidoptera. To produce collard lines expressing Bt genes, a ...

Betulin (BT) has been identified to exhibit potential benefits for treating hepatocellular carcinoma (HCC). The results of the present study demonstrated that a new semisynthetic derivative of BT, 3,28-di-(2-nitroxy-acetyl)-oxy-BT, may effectively decrease the viability of Huh7 cells. Mechanistic studies revealed that 3,28-di-(2-nitroxy-acetyl)-oxy-BT inhibited the transition between G2 and M p...

This study quantifies the regional distribution of the micropollutant benzothiazole (BT) in river water by sampling 15 river sites in the Schwarzbach watershed (about 400 km(2)) from November 2008 to February 2010. Additionally, wastewater samples from three municipal wastewater treatment plants (WWTPs) in Germany were analyzed. BT was detected in all wastewater influent and effluent samples as...
