The role of oxidative stress in male infertility: Connection to sperm telomere shortening and overall DNA damage [PDF]

Arhiv za farmaciju
Male infertility affects approximately 20% of men, with 30-40% of cases being linked to issues in both partners. While sperm production may be normal, DNA damage in spermatozoa can occur and become a primary cause of infertility.

Effector Caspase Dcp-1 and IAP Protein Bruce Regulate Starvation-Induced Autophagy during Drosophila Melanogaster Oogenesis [PDF]

, 2008
A complex relationship exists between autophagy and apoptosis, but the regulatory mechanisms underlying their interactions are largely unknown. We conducted a systematic study of Drosophila melanogaster cell death–related genes to determine their ...

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

Animal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Sperm DNA fragmentation testing: an evolving frontier [PDF]

Translational Andrology and Urology, 2017
The management of patients with male infertility is a complex topic with a vast scope in terms of biological and historical importance. Infertile men have played hugely important roles in world history (Abraham, George Washington, Louis XVI); their treatment has been a focus of interest for not just physicians, but also the religious (fertility priests,

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

The effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men

Research in Molecular Medicine, 2020
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity.
