To date Rhabdias gemellipara is the only species described from Malagasy chameleons, but heterogeneity of the material had been suspected. 11 samples of Rhabdias parasites present in the Paris Natural History Museum collection were examined. The size and shape of the buccal capsule, shape and length of the oesophagus, shape of the apical region of the intestine, extent of the genital tract and ...

17-α-methyltestosterone (MT) is a synthetic hormone used in fish hatcheries to induce male monosex. Snails hold promise as possible test models to assess chemicals acting on the endocrine system. Biomphalaria glabrata is an aquatic gastropod mollusk (Pulmonata, Planorbidae) that can be easily maintained in aquaria, predisposing the species for use in ecotoxicological testing. This study evaluat...

Primary ciliary dyskinesia (PCD) is a rare recessive disease with a prevalence of 1/10,000; its symptoms are caused by a kinetic dysfunction of motile cilia in the respiratory epithelium, flagella in spermatozoids, and primary cilia in the embryonic node. PCD is genetically heterogeneous: genotyping the already known PCD-related genes explains the genetic basis in 60-65% of the cases, depending...

PURPOSE We assessed reproductive and testicular function in adult rats after testicular torsion created before, during and after puberty, and with vs without resveratrol or arginine treatment. MATERIALS AND METHODS Age matched rats were divided into groups, including simulated surgery without testicular torsion, 720-degree testicular torsion for 4 hours, testicular torsion with resveratrol tr...

BACKGROUND Mesenchymal stem cells (MSCs) are undifferentiated cells that can differentiate and divide to other cell types. Transplantation of these cells to the different organs is used for curing various diseases. OBJECTIVE The aim of this research was whether MSCs transplantation could treat the sterile testes. MATERIALS AND METHODS In this experimental study, Donor MSCs were isolated fro...

OBJECTIVES To evaluate the incidence of functional and chromatin alterations on spermatozoids in patients grouped according to normality of standard semen parameters based on the 5th edition of the World Health Organization (WHO) guidelines. To identify and correlate the most frequently altered characteristics in the normal standard semen parameters sub-population. MATERIALS AND METHODS A pro...

One of the A. aurita medusa main mesoglea polypeptides, mesoglein, has been described previously. Mesoglein belongs to ZP-domain protein family and therefore we focused on A.aurita oogenesis. Antibodies against mesoglein (AB RA47) stain the plate in the place where germinal epithelium contacts oocyte on the paraffin sections. According to its position, we named the structure found the "contact ...

Protein Disulfide Isomerase-Like protein of the Testis (PDILT) is a testis-specific member of the PDI family. PDILT displays similar domain architecture to PDIA1, the founding member of this protein family, but lacks catalytic cysteines needed for oxidoreduction reactions. This suggests special importance of chaperone activity of PDILT, but how it recognizes misfolded protein substrates is unkn...

Background: Increase of blood glucose leads to structural and functional changes in various target tissues and organs. Gonadal dysfunction and decrease in testosterone production are the consequence of diabetes and these conditions lead to insufficient production of spermatozoids. Besides the use of chemical agents, herbal medications for treatment and reduction of diabetic side effects have be...
