Different staining techniques evaluation for the study of sperm morphology and morphometry in bats (Mammalia: Chiroptera)

open access: yesActa Zoológica Lilloana
The study of sperm morphology involves the use of various staining techniques that allow visualization of different structures of the spermatozoon and their variabili- ty.

Early neuronal accumulation of DNA double strand breaks in Alzheimer's disease. [PDF]

open access: yes, 2019
The maintenance of genomic integrity is essential for normal cellular functions. However, it is difficult to maintain over a lifetime in postmitotic cells such as neurons, in which DNA damage increases with age and is exacerbated by multiple neurological

Digital staining facilitates biomedical microscopy

open access: yesFrontiers in Bioinformatics, 2023
Traditional staining of biological specimens for microscopic imaging entails time-consuming, laborious, and costly procedures, in addition to producing inconsistent labeling and causing irreversible sample damage. In recent years, computational “virtual”

Quantitative determination of fluorescence labeling implemented in cell cultures

open access: yesBMC Biology, 2023
Background Labeling efficiency is a crucial parameter in fluorescence applications, especially when studying biomolecular interactions. Current approaches for estimating the yield of fluorescent labeling have critical drawbacks that usually lead them to ...

Method for observing Beauveria bassiana colonization in plants

open access: yesMethodsX, 2021
Microbes interact in a multitude of ways with host plants, can dwell as endophytes within plants causing no apparent disease, and often provide benefits to their host.

Reversal of terminal differentiation and control of DNA replication [PDF]

open access: yes, 1993
DNA replication in mammalian cells occurs in discrete nuclear foci. Here we show that terminally differentiated myotubes can be induced to reenter S phase and show the same pattern of replication foci as cycling cells.

Olig2/Plp-positive progenitor cells give rise to Bergmann glia in the cerebellum. [PDF]

open access: yes, 2013
NG2 (nerve/glial antigen2)-expressing cells represent the largest population of postnatal progenitors in the central nervous system and have been classified as oligodendroglial progenitor cells, but the fate and function of these cells remain ...

Citron binds to PSD-95 at glutamatergic synapses on inhibitory neurons in the hippocampus [PDF]

open access: yes, 1999
Synaptic NMDA-type glutamate receptors are anchored to the second of three PDZ (PSD-95/Discs large/ZO-1) domains in the postsynaptic density (PSD) protein PSD-95.
