Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Progeny of Germ Line Knockouts of \u3cem\u3eASI2\u3c/em\u3e, a Gene Encoding a Putative Signal Transduction Receptor in \u3cem\u3eTetrahymena Thermophila\u3c/em\u3e, Fail to Make the Transition from Sexual Reproduction to Vegetative Growth [PDF]

open access: yes, 2006
The ciliated protozoan Tetrahymena has two nuclei: a germ line micronucleus and a somatic macronucleus. The transcriptionally active macronucleus has about 50 copies of each chromosome.

A novel splice variant of the DNA-PKcs gene is associated with clinical and cellular radiosensivity in a patient with xeroderma pigmentosum [PDF]

open access: yes, 2010
Background: Radiotherapy-induced DNA double-strand breaks (DSBs) are critical cytotoxic lesions. Inherited defects in DNA DSB repair pathways lead to hypersensitivity to ionising radiation, immunodeficiency and increased cancer incidence.

WR-2721: Inhibitor of cisplatin-induced micronuclei

open access: yesTeratogenesis, Carcinogenesis, and Mutagenesis, 2000
The modulatory effect of S-2-/3-aminopropylamino/ethyl-phosphorothioic acid, (WR-2721, Amifostine) on induction of micronuclei by cis-diamminedichloroplatinum[II] (CDDP) was studied. The adult, male Swiss mice were treated with WR-2721, at a dose of 200 mg/kg or 400 mg/kg body weight, and/or with CDDP, at a dose 5 mg/kg or 10 mg/kg body weight. WR-2721

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as

Cytomorphological changes of oral mucosal cells among smokeless tobacco users in low and middle-income country settings: new findings from Pakistan

open access: yesBMC Oral Health
Background Chronic tobacco use, in any form, induces significant cellular alterations in the oral mucosa. This study investigates four distinct cytomorphological changes in oral mucosal cells among smokeless tobacco users, examining their association ...

Technical note on cytokinesis-arrested binucleated cell and micronucleus assay

open access: yesJournal of Radiation and Cancer Research, 2017
Conventionally, many biomarkers are being in use as a measure to genotoxicity in occupational exposure to chemicals, pesticides, radiation, and drug screening. Of which, the micronucleus assay is a preferred choice for many of those applications owing to

Laser Microirradiation of Chinese Hamster Cells at Wavelength 365 nm [PDF]

open access: yes, 1981
Cells of a V79 subline of the Chinese hamster were microirradiated at wavelength 365 nm in the presence of the psoralen derivative, trioxsalen. Microirradiation was accomplished by a pulsed argon laser microbeam either in anaphase or in interphase 3 hr ...
