In recent years, the field of male-mediated reproductive toxicology has received growing attention. It is now well-established that many drugs, chemicals, and environmental factors can harm male germ cells by inducing DNA damage. Male germ cells have extensive repair mechanisms that allow detection and repair of damaged DNA during the early phases of spermatogenesis. However, during the later phase of spermiogenesis, when the haploid spermatids undergo chromatin condensation and become transcriptionally quiescent, their ability to repair damaged DNA is lost. It is also thought that the highly compacted chromatin of the sperm can protect DNA against damage. Therefore, it is expected that late spermatids will be most susceptible to DNA damaging agents. Unrepaired or misrepaired damage in the germ cells leads to the generation of spermatozoa with DNA damage that can be transmitted to the next generation. Fortunately, the maternal DNA repair machinery is capable of recognizing and repairing, at least to some degree, damaged paternal DNA after fertilization in the zygote. Therefore, the efficiency of the maternal repair machinery will greatly influence the risk of transmitting paternal DNA damage to offspring.

After the microbiology based on Pasteur's method and polymerase chain reaction(PCR), the diagnosis company named Dendris has proposed a third-generation of diagnosis enabling the search of a broad range of pathogens with strong sensitivity and specificity. This extraordinary profile was possible thanks to the use of phosphorus dendrimers for which various techniques of deposition on a given support were investigated and described and analyzed in this report.

AIM: To investigate whether the expression of platelet-derived growth factor receptor-α-positive (PDGFRα+)-cells is altered in Hirschsprung’s disease (HD).METHODS: HD tissue specimens (n = 10) were collected at the time of pull-through surgery, while colonic control samples were obtained at the time of colostomy closure in patients with imperforate anus (n = 10). Immunolabelling of PDGFRα+-cells was visualized using confocal microscopy to assess the distribution of these cells, while Western blot analysis was undertaken to quantify PDGFRα protein ***: Confocal microscopy revealed PDGFRα+-cells within the mucosa, myenteric plexus and smooth muscle in normal controls, with a marked reduction in PDGFRα+-cells in the HD specimens. Western blotting revealed high levels of PDGFRα protein expression in normal controls, while there was a striking decrease in PDGFRα protein expression in the HD ***: These findings suggest that the altered distribution of PDGFRα+-cells in both the aganglionic and ganglionic HD bowel may contribute to the motility dysfunction in HD.

The 17q12-21 locus harboring ORMDL sphingolipid biosynthesis regulator 3(ORMDL3)and Gasdermin B(GSDMB)genes exhibits one of the most significant and replicated associations with asthma[MIM:600807](Stein et al.,2018).Several studies explored the complex interactions between SNPs,gene expression and epigenetic modifications at this locus,primarily focusing on the levels of expressed ORMDL3 and GSDMB(Stein et al.,2018).Given that DNA methylation and gene expression signals are cell-type specific(Reinius et al.,2012),isolated materials such as lymphocytes from blood and,to a lesser extent,bronchial epithelial cells from biopsies of bronchi or bronchoalveolar lavages have been used in a number of studies to investigate such interactions(Stein et al.,2018).
