Yeast-Based Synthetic Biology Platform for Antimicrobial Peptide Production.

Antibiotic resistance is one of the most challenging global health threats in our society. Antimicrobial peptides (AMPs) represent promising alternatives to conventional antibiotics for the treatment of drug-resistant infections. However, they are limited by their high manufacturing cost.

Evaluation of retention of knowledge and skills imparted to first-year medical students through basic life support training.

Poor awareness among medical graduates about basic life support (BLS) is a matter of great concern. The presence of a trained rescuer is the key determinant of ultimate survival from life-threatening emergencies. To achieve this goal, early exposure to such life-saving skills is the right decision to foster these skills for medical students, which can be reenforced in succeeding years.

Assessment of cardiovascular response to treadmill exercise in normal healthy Indian adolescents.

The study aims to assess the cardiovascular response to treadmill exercise test in healthy Indian adolescents. A group of 50 healthy adolescents took part in the study. Cardiovascular response was assessed by using treadmill exercise test as per Bruce protocol.

Lactobacillus brevis responds to flavonoids through KaeR, a LysR-type of transcriptional regulator.

The ability of transcription factors to respond to flavonoids as signal molecules was investigated in Lactobacillus brevis. Through in vitro screening of a small library of flavonoids, LVIS1989 (KaeR), a LysR-type transcriptional regulator (LTTR), was identified as responsive to kaempferol. The modulation of KaeR activity by flavonoids was characterized in vivo and in vitro.

LVIS553 transcriptional regulator specifically recognizes novobiocin as an effector molecule.

In this study we aimed to identify small molecules with high affinity involved in the allosteric regulation of LVIS553, a MarR member from Lactobacillus brevis ATCC367. Using high throughput screening, novobiocin was found to specifically bind LVIS553 with a K(D) = 33.8 +/- 2.
