El sistema reproductor femenino de Zearaja chilensis (Guichenot, 1848) (Chondrichthyes, Rajidae): Gametogénesis y validación microscópica de los criterios de madurez [PDF]

open access: yes, 2015
Los condrictios son extremadamente susceptibles a la explotación pesquera debido, entre otras cosas, a sus adaptaciones reproductivas. Los conocimientos básicos de sus parámetros reproductivos son esenciales, ya sea desde el punto de vista ecológico como

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

open access: yes, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Synergistic effects of dendrosomal nanocurcumin and oxaliplatin on oncogenic properties of ovarian cancer cell lines by down-expression of MMPs

open access: yesBiological Research, 2023
Background Contrary to the advantageous anticancer activities of curcumin (Cur), limited bioavailability and solubility hindered its efficacy. Here, nontoxic dendrosomal nano carrier with Cur was used to overcome these problems.

Retinoblastoma makes its mark on imprinting in plants [PDF]

open access: yes, 2008
Genomic imprinting results in the preferential expression of alleles from either the maternal or paternal chromosomes. This epigenetic process occurs in embryonic and extra-embryonic (placental) tissues of mammals, but only in the extra-embryonic ...

Cryoprotectants in ovarian vitrification: A review

open access: yesFiyz̤, 2021
Background: The survival of cells after the difficult process of cryopreservation and warming is possible only by using appropriate methods of cryopreservation and the use of appropriate cryoprotective agents (CPAs).

Developmental regulation of an organelle tether coordinates mitochondrial remodeling in meiosis. [PDF]

open access: yes, 2018
Cellular differentiation involves remodeling cellular architecture to transform one cell type to another. By investigating mitochondrial dynamics during meiotic differentiation in budding yeast, we sought to understand how organelle morphogenesis is ...

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]

open access: yes, 2016
Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific

Plasmodium Condensin Core Subunits SMC2/SMC4 Mediate Atypical Mitosis and Are Essential for Parasite Proliferation and Transmission [PDF]

open access: yes, 2020
Condensin is a multi-subunit protein complex regulating chromosome condensation and segregation during cell division. In Plasmodium spp., the causative agent of malaria, cell division is atypical and the role of condensin is unclear.

Association of -308G/A TNFα gene polymorphism with reduced risk of idiopathic infertility in men

open access: yesFiyz̤, 2022
Background: Infertility is one of the major health problems in the world and several factors play a role in the occurrence of this complication. One of the causes of idiopathic male infertility is a defect in the process of spermatogenesis due to ...
