Review of the Molecular and Developmental Basis of Myhre Syndrome, Bench Research

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome (MS) is a connective‐tissue disorder within the acromelic dysplasia spectrum. It is characterized by congenital craniofacial, skeletal, cutaneous anomalies, respiratory, cardiovascular along with intellectual disability, deafness, and progressive fibrosis.

Expression of Tas1 taste receptors in mammalian spermatozoa [PDF]

open access: yes, 2012
Background: During their transit through the female genital tract, sperm have to recognize and discriminate numerous chemical compounds. However, our current knowledge of the molecular identity of appropriate chemosensory receptor proteins in sperm is ...

Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

open access: yesAnimal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Patch clamp studies of human sperm under physiological ionic conditions reveal three functionally and pharmacologically distinct cation channels [PDF]

open access: yes, 2014
Whilst fertilizing capacity depends upon a K+ conductance G? that allows the spermatozoon membrane potential Vm to be held at a negative value, the characteristics of this conductance in human sperm are virtually unknown.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

CHARACTERISTIC OF FROZEN-THAWED EPIDIDYMAL SPERMATOZOA AND REFRIGERATED STORAGE OF RAM SPERMATOZOA [PDF]

open access: yes, 2010
Post-mortem spermatozoa recovery is an important technique for obtaining germplasm reserves from genetically valuable animals or endangered species. The purpose of this study was to study whether ram spermatozoa within epididymides stored at 4º C for ...

Effects of Diethylstilbestrol Administration on Sperm Motility and Reproductive Function in Male Japanese Quail (Coturnix japonica)

open access: yesThe Journal of Poultry Science, 2002
The present study was undertaken to evaluating the effects of diethylstilbestrol (DES) on sperm motility and reproductive function in male Japanese quail. To do so, we have identified the method that ensures maximal quail sperm motility, i.e.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...
