Effects of L-carnitine and pentoxifylline on long-term preservation of the human sperms: An experimental study.
Int J Reprod Biomed
November 2024
Histomorphometry and Stereology Research Center, Anatomy Department, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran.
Background: In infertility clinics, long-time preserving high-quality spermatozoa is a challenging problem.
Objective: The present study aimed to prolong preserving of the human spermatozoa by adding pentoxifylline (PT) and L-carnitine (LC) without using high-cost freezing techniques.
Materials And Methods: In this experimental study, semen samples of 26 normozoospermia men aged between 28-34 yr, were firstly prepared using the swim-up technique, and each sample was divided into the following 3 aliquots: untreated control group, the LC, and PT-treated groups.
Metabolomic Profiles of Siberian Wood Frog in Hypoxia and Upon Reoxygenation.
Biochemistry (Mosc)
December 2024
Institute of the Biological Problems of the North, Far Eastern Branch of the Russian Academy of Sciences, Magadan, 630058, Russia.
Hypoxia poses a serious challenge for all animals; however, certain animals exhibit a remarkable resilience in the case of prolonged and severe hypoxia. The Siberian wood frog is a unique amphibian capable of surviving for up to several months at almost complete anoxia. We investigated changes in the metabolome of at the onset of hypoxia (day 1) and within 1 h of reoxygenation after a long-term hypoxia using H NMR.

Spaceflight occurs under extreme environmental conditions that pose significant risks to the physical and mental health and well-being of astronauts. Certain factors, such as prolonged isolation, monotony, disrupted circadian rhythms, heavy workload, and weightlessness in space, can trigger psychological distress and may contribute to a variety of mental health problems, including mood and anxiety disturbances. Recent findings regarding spaceflight-associated alterations in cerebrospinal fluid spaces, demonstrating enlargement of the brain's perivascular spaces from preflight to postflight, at least suggest reduced glymphatic clearance in microgravity, and have raised concerns about long-term cognitive health in astronauts.

College of Food Science and Technology, Hebei Agricultural University, Baoding 071001, China. Electronic address:
The shelf-life of grapes is reduced due to infection by various pathogens and mechanical damage, which consequently limits their availability on the market and results huge economic losses. Active packaging films are expected to overcome this problem. In this study, packaging films (CMC-Gly-PMA) were developed using wheat straw-based carboxymethyl cellulose (2 %), glycerol (30 % w/w of CMC) and polymalate (0.

Weeds cause a decrease in the quantity and quality of agricultural production and economic damage to producers. The prolonged use of synthetic pesticides causes problems of environmental pollution, the possible alteration of agricultural products and problems for human health. For this reason, the scientific community's search for products of natural origin, which are biodegradable, safe for human health and can act as valid alternatives to traditional herbicides, is growing.
