Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development

Environmental Toxicology, EarlyView.
ABSTRACT Parabens are synthetic chemicals that, due to their antibacterial and fungicidal effects, are widely used as preservatives in food, cosmetics, and personal care products, such as shampoos, hair conditioners, body creams, soaps, deodorants, makeup, wet wipes, lotions, female hygiene products, and vaginal lubricants. Several years ago, they were

Role of testicular fine‐needle aspiration in the modern male reproductive urologist′s practice

UroPrecision, EarlyView.
Abstract Background Azoospermia affects 10%–15% of infertile men, with non‐obstructive azoospermia (NOA) most often managed by microdissection testicular sperm extraction (mTESE). Despite AUA/ASRM guidelines recommending mTESE, some urologists employ testicular fine‐needle aspiration (TFNA) mapping as a diagnostic adjunct.

Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

Veterinary Record, EarlyView.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...
