Mechanism of Anti-rotavirus Synergistic Activity by Epigallocatechin Gallate and a Proanthocyanidin-Containing Nutraceutical.

Epigallocatechin gallate (EGCG) of green tea and the nutraceutical CystiCran-40 (containing 40% proanthocyanidins) of the cranberry plant have been associated with antiviral activity. The purpose of this work was to determine the mechanism of antiviral synergy between each compound. Coliphage T4II (phage T4) and the rotavirus strain SA-11(RTV) were used as model virus systems.

The molecular genetic architecture of attention deficit hyperactivity disorder.

Attention deficit hyperactivity disorder (ADHD) is a common childhood behavioral condition which affects 2-10% of school age children worldwide. Although the underlying molecular mechanism for the disorder is poorly understood, familial, twin and adoption studies suggest a strong genetic component. Here we provide a state-of-the-art review of the molecular genetics of ADHD incorporating evidence from candidate gene and linkage designs, as well as genome-wide association (GWA) studies of common single-nucleotide polymorphisms (SNPs) and rare copy number variations (CNVs).

Tribal formulations for treatment of pain: a study of the Bede community traditional medicinal practitioners of Porabari Village in Dhaka District, Bangladesh.

The Bedes form one of the largest tribal or indigenous communities in Bangladesh and are popularly known as the boat people or water gypsies because of their preference for living in boats. They travel almost throughout the whole year by boats on the numerous waterways of Bangladesh and earn their livelihood by selling sundry items, performing jugglery acts, catching snakes, and treating village people by the various riversides with their traditional medicinal formulations. Life is hard for the community, and both men and women toil day long.

Medicinal plants used by the Mandais--a little known tribe of Bangladesh.

The Mandais are a little known tribe of Bangladesh inhabiting the north central regions, particularly Tangail district of Bangladesh. Their population has been estimated to be less than 10,000 people. Although the tribe has for the most part assimilated with the mainstream Bengali-speaking population, they to some extent still retain their original tribal customs, including their traditional medicinal practices.

Differential responses of Bacillus subtilis rRNA promoters to nutritional stress.

The in vivo expression levels of four rRNA promoter pairs (rrnp(1)p(2)) of Bacillus subtilis were determined by employing single-copy lacZ fusions integrated at the amyE locus. The rrnO, rrnJ, rrnD, and rrnB promoters displayed unique growth rate regulation and stringent responses. Both lacZ activity and mRNA levels were highest for rrnO under all growth conditions tested, while rrnJ, rrnB, and rrnD showed decreasing levels of activity.
