Mobile Food Tracking Apps: Do They Provoke Disordered Eating Behavior? Results of a Longitudinal Study.

Background: Some studies connect the popularity of food-tracking apps to an increase in restrictive eating and other disordered eating behaviors and find those apps harmful for psychological well-being, but there is a lack of empirical studies, especially of Russian samples.

Objective: To examine the connection between disordered eating symptoms, psychological well-being, and the use of a mobile food-tracking application.

Design: The participants were 26 women aged 18-30 ( = 21.

Comparative Characteristic of the Methods of Isolation of Oocytes and Spermatozoa in Laboratory Animals (Review).

Over the past decade, there has been an increasing trend in the use of assisted reproductive technologies, which have significantly expanded the opportunities to overcome the problem of infertility. However, the problem of increasing the effectiveness of in vitro fertilization remains open. Isolation of germ cells from animals is a necessary process for various experimental studies.

as a Platform for Heterologous Expression of Enzymes Used for Industry.

In the 1980s, was the preferred host for heterologous protein expression owing to its capacity for rapid growth in complex media; well-studied genetics; rapid and direct transformation with foreign DNA; and easily scalable fermentation. Despite the relative ease of use of for achieving the high expression of many recombinant proteins, for some proteins, e.g.

Heterologous Expression of Extracellular Proteinase pAsPs of in .

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.

Heterologous Expression of Xylanase xAor from Aspergillus oryzae in Komagataella phaffii T07.

Xylanases (EC 3.2.1.
