MITOCHONDRIAL DNA POLYMORPHISMS AND FERTILITY IN BEEF CATTLE [PDF]

open access: yes, 2002
Two regions of mitochondrial DNA, D-loop and ND-5 were characterized using polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP) involving 422 beef cattle of Hereford and composite breeds from Wokalup’s ...

Three‐Dimensional Influence of Photobiomodulation on Adipose‐Derived Stem Cell Behavior

open access: yesJournal of Biophotonics, EarlyView.
Photobiomodulation (PBM) at 825 nm is evaluated on adipose‐derived stem cells cultured in 2D and 3D models. PBM enhanced cell viability and proliferation, with 5 J/cm2 showing strong effects in 2D, and 10 J/cm2 in 3D spheroids. Results show 3D provides a more physiologically relevant platform for assessing PBM‐induced regenerative responses.

Propentofylline reduces glial scar development following gliotoxic damage in the rat brainstem

open access: yesArquivos de Neuro-Psiquiatria
Propentofylline is a xanthine derivative that depresses activation of glial cells, whose responses contribute to neural tissue damage during inflammation.

Taxonomic investigation of Abrothallus (Abrothallales, Ascomycota) species associated with lichen genera Ramalina and Bryoria, including the description of a new species

open access: yesNordic Journal of Botany, EarlyView.
The obligately lichenicolous genus Abrothallus consists of approximately 50 species, almost all of which are associated with lichens having foliose, fruticose, or pendulous thalli. This paper focuses on species that grow on strap lichens (Ramalina) providing new insights into their phylogenetic relationships and distribution.

Selective in vivo damage by "visible" light of BrdU-containing mitochondrial DNA in a thymidine kinase-deficient mouse cell line with persistent mitochondrial enzyme activity [PDF]

open access: yes, 1975
The selective incorporation of 5-bromodeoxyuridine (BrdU) into mitochondrial DNA (mit-DNA) in the LM(TK-) Cl ID cell line, a thymidine kinase-deficient derivative of L, fibrobla8ts with persistent mitochondrial enzyme activity, has been utilized to ...

Modifying Antibiotic Activity of Synthetic Thiadiazine Analogs Against MDR Bacteria and ADMET Analysis

open access: yesChemistryOpen, EarlyView.
The study demonstrated that thidiazine compounds potentiated the action of antibiotics. The compounds associated with norfloxacin against S. aureus showed greater significance in relation to the other medications. The indiscriminate use of antibiotics has led to the selection of resistant bacterial strains, significantly reducing the effectiveness of ...

Identifying Subcellular Structure Components in Escherichia Coli by Crosslinking and SEC‐MS

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Cells are comprised of a broad spectrum of structures that compartmentalize biochemical and signaling mechanisms. These structures can be comprised of many biomolecules, but especially lipids, proteins, and nucleic acids. Techniques are limited to quantify or discover new subcellular structures.
