Technologies for the Production of Fertilizable Mammalian Oocytes

open access: yesApplied Sciences, 2019
Women affected by ovarian pathologies or with cancer can usually preserve fertility by egg/embryo freezing. When oocyte retrieval is not feasible, the only option available is ovarian tissue cryopreservation and transplantation.

Pathogenesis of androgenetic alopecia

open access: yesClinical Dermatology Review, 2022
The pathogenesis of androgenetic alopecia (AGA) is a complex interplay of genetic, hormonal, and environmental factors. In scalp follicles of susceptible individuals, androgens promote miniaturization of hair and shorten hair growth in the anagen stage ...

Hair follicle proteoglycans

open access: yesJournal of Investigative Dermatology, 1993
Proteoglycans are polymorphic macromolecules present in all mammalian tissues, including the skin and its appendages. They consist of a core protein to which one or more glycosaminoglycan chains are covalently attached. Broadly, they can be divided into classes based on location and core protein structure.

TGF-beta superfamily members and ovarian follicle development.

open access: yesReproduction, 2006
In recent years, exciting progress has been made towards unravelling the complex intraovarian control mechanisms that, in concert with systemic signals, coordinate the recruitment, selection and growth of follicles from the primordial stage through to ...

Alopecia areata: a multifactorial autoimmune condition [PDF]

open access: yes, 2019
Alopecia areata is an autoimmune disease that results in non-scarring hair loss, and it is clinically characterised by small patches of baldness on the scalp and/or around the body. It can later progress to total loss of scalp hair (Alopecia totalis) and/

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Steroid profile of porcine follicular fluid and blood serum: Relation with follicular development

open access: yesPhysiological Reports, 2019
The aim of this study was to identify follicular fluid (FF) steroids which reflect follicular development in the early stages of the follicular phase and to establish whether the levels of these FF steroids correspond to their levels in serum.

Induction of accessory corpus luteum by gonadorelin in relation to the time of treatment and the follicle size in inseminated cows

open access: yesCzech Journal of Animal Science, 2017
This study evaluated the occurrence of two corpora lutea (CL) and the pregnancy rate in cows treated with gonadorelin on days 5, 6 or 7 after insemination in relation to the day of treatment and the size of the largest follicle on the ovaries at the time

Inferring simple but precise quantitative models of human oocyte and early embryo development [PDF]

open access: yesarXiv, 2021
Macroscopic, phenomenological models have proven useful as concise framings of our understandings in fields from statistical physics to economics to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature of oogenesis and embryogenesis.

Improving the reproductive performance of the Muturu breed of cattle in Nigeria using modified Ovsynch and progesterone synchronization protocol : a thesis presented in partial fulfilment of the requirement for the degree of Master of Science in Animal Science, Institute of Veterinary, Animal and Biomedical Sciences, Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2017
The Ovsynch protocol has been used in cattle to synchronize ovulation and facilitate fixed-time AI (FTAI) but its efficacy has not been evaluated in the Nigerian Muturu breed of B. indicus cattle. The effects of a modified Ovsynch protocol (modified by
