The effect of supplementing freezing extender with Mn-, Zn- or Cu-nanosuccinate on select post-thaw characteristics of ram semen.

The effects of Mn-, Zn- or Cu-nanosuccinate added to freezing extender on select post-thaw semen characteristics were determined in six Texel rams (aged 2-4 years) during seasonal anestrus (April-May). Ejaculates (n = 6 per ram) collected into an artificial vagina were divided into ten isovolumetric fractions each. Semen was diluted in lactose-yolk-tris-citrate-glycerin medium and nanosuccinates (Mn- and Zn-nanosuccinate: 0.

A New 4-Thiazolidinone Derivative (Les-6490) as a Gut Microbiota Modulator: Antimicrobial and Prebiotic Perspectives.

A novel 4-thiazolidinone derivative Les-6490 (pyrazol-4-thiazolidinone hybrid) was designed, synthesized, and characterized by spectral data. The compound was screened for its antimicrobial activity against some pathogenic bacteria and fungi and showed activity against and (the Minimum Inhibitory Concentration (MIC) 820 μM). The compound was studied in the rat adjuvant arthritis model (Freund's Adjuvant) in vivo.

Hypoxia modeling techniques: A review.

Hypoxia is the main cause and effect of a large number of diseases, including the most recent one facing the world, the coronavirus disease (COVID-19). Hypoxia is divided into short-term, long-term, and periodic, it can be the result of diseases, climate change, or living and traveling in the high mountain regions of the world. Since each type of hypoxia can be a cause and a consequence of various physiological changes, the methods for modeling these hypoxias are also different.

Effects of embryonic exposure to chromium (VI) on blood parameters and liver microstructure of 1-day-old chickens.

Hexavalent chromium (Cr(VI)) has carcinogenic, nephrotoxic, hepatotoxic, and neurotoxic effects. Exposure to Cr(VI) can also lead to hematological alterations and blood biochemical changes. The literature on Cr(VI) toxicity concerns mostly adult forms of vertebrates.

Neutrophils as Main Players of Immune Response Towards Nondegradable Nanoparticles.

Many nano/microparticles (n/µP), to which our body is exposed, have no physiological way of removal. Our immune system sense these "small particulate objects", and tries to decrease their harmfulness. Since oxidation, phagocytosis and other methods of degradation do not work with small, chemically resistant, and hydrophobic nanoparticles (nP).
