Neutral protease pAsPs gene was obtained by sequence optimization of NpI protease from pAsPs was for the first time integrated in the genome of yeast strain T07, and then produced in a 5 L bioreactor with an enzyme yield of 150,800 U/mL of culture liquid towards casein. The specific activity of the pAsPs was 7,657,000 U/mg toward casein, 2320 U/mg toward hemoglobin, and 25,344 U/mg toward azocasein per 1 mg of the protein. The enzyme was found to be inhibited by Cu.

A fluorescent biosensor /pTdcR-TurboYFP sensitive to terahertz (THz) radiation was developed via transformation of () cells with plasmid, in which the promotor of the gene controls the expression of yellow fluorescent protein TurboYFP. The biosensor was exposed to THz radiation in various vessels and nutrient media. The threshold and dynamics of fluorescence were found to depend on irradiation conditions.

Article Synopsis
  • - Three new fluorescent biosensors were created by inserting plasmids into cells, which regulated the expression of fluorescent proteins using specific gene promoters.
  • - These biosensors were tested with two types of THz radiation: a powerful short-wave laser and a weaker continuous-wave device, showing that fluorescence levels varied based on the type and duration of radiation exposure.
  • - The study found that stress from heat or chemicals prevented fluorescence, indicating these biosensors could be useful for examining how THz radiation affects gene networks associated with the targeted gene promoters.

Background: As the standard clinically used hypotensive medicines have many undesirable side effects, there is a need for new therapeutic agents, especially ones of a natural origin.

Purpose: One possible candidate is extract from the mushroom Reishi (Ganoderma lucidum), which is used in the treatment and prevention of many chronic diseases.

Study Design And Methods: To study the effectiveness of Reishi, which grows in the Altai Mountains, as an antihypertensive agent, we intragastrically administered Reishi water extract to adult male hypertensive ISIAH (inherited stress-induced arterial hypertension) rats.

Studies of the impact of terahertz radiation on living objects present a significant interest since its use for security systems is currently considered promising. We studied the non-thermal impact of terahertz radiation on E. coli/pKatG-gfp biosensor cells.
