Background Protamination and condensation of sperm chromatin as well as dnA integrity play an essential role during fertilization and embryo *** some mammals,like pigs,ejaculates are emitted in three separate fractions:pre-sperm,sperm-rich(SRF)and post sperm-rich(PSRF).These fractions are known to vary in volume,sperm concentration and quality,as well as in the origin and composition of seminal plasma(SP),with differences being also observed within the SRF ***,whether disparities in the dnA integrity and chromatin condensation and pro-tamination of their sperm exist has not been *** This study determined chromatin protamination(chromomycin A3 test,cMA_(3)),condensation(dibromobi-mane test,dBB),and dnA integrity(comet assay)in the pig sperm contained in the first 10 m L of the SRF(SRF-P1),the remaining portion of the sperm-rich fraction(SRF-P2),and the post sperm-rich fraction(PSRF).While chromatin protamination was found to be similar between the different ejaculate fractions(P>0.05),chromatin condensation was seen to be greater in SRF-P1 and SRF-P2 than in the PSRF(P=0.018 and P=0.004,respectively).Regarding dnA integrity,no differences between fractions were observed(P>0.05).As the SRF-P1 has the highest sperm concentra-tion and ejaculate fractions are known to differ in antioxidant composition,the oxidative stress index(OSi)in SP,calcu-lated as total oxidant activity divided by total antioxidant capacity,was tested and confirmed to be higher in the SRF-P1 than in SRF-P2 and PSRF(0.42±0.06 vs.0.23±0.09 and 0.08±0.00,respectively;Pndex,in addition,was observed to be correlated to the sperm concentration of each fraction(Rs=0.973;Pconclusion While sperm dnA integrity was not found to differ between ejaculate fractions,SRF-P1 and SRF-P2 were observed to exhibit greater chromatin condensation than the *** could be related to the OSi of each fraction.

This work shows that despite a lattice mismatch of almost 20%, cdMnTe/cdTe/cdMnTe heterostructures grown directly on Si(111) have surprisingly good optical emission properties. The investigated structures were grown by molecular beam epitaxy and characterized by scanning transmission electron microscopy, macro-and micro-photoluminescence. Low temperature macro-photoluminescence experiments indicate three emission bands which depend on the cdTe layer thickness and have different confinement characteristics. Temperature measurements reveal that the lower energy emission band (at 1.48 ev)is associated to defects and bound exciton states, while the main emission at 1.61 ev has a weak 2d character and the higher energy one at 1.71 ev has a well-defined (zero-dimensional, 0d) 0d nature. Micro-photoluminescence measurements show the existence of sharp and strongly circularly polarized (up to 40%) emission lines which can be related to the presence of Mn in the heterostructure. This result opens the possibility of producing photon sources with the typical spin control of the diluted magnetic semiconductors using the low-cost silicon technology.

Background: Extrinsic aging results from environmental stressors such as UvR or pollutants. While the effects of single pollutants are better understood, those of their combination remain poorly scrutinized. Objective: Building on a study showing downregulation of several processes upon co-exposure to B[a]P and UvA, we investigated changes induced by epigenetic marks. Materials and Methods: Human primary fibroblasts and HacaT cells were exposed to B[a]P and UvA. After 24 hours, exposed and unexposed cells were compared to assess dnA methylation. Focusing on HacaT, multiplex assays enabled quantifying histone H3 modifications and evaluating four splicing factors (SRSF1, SRSF3, SFPQ, and SF3B1) by immunohistochemical labeling. The expression of keratinocyte-/fibroblast-relevant genes was assessed by RT-qPcR. Finally, the impact of an Arundo donax L. extract added 24 hours before B[a]P-UvA co-exposure was analyzed. Results: Exposure to B[a]P-UvA raised dnA methylation (HacaT: ×3.6, fibroblasts: ×1.9), an increase prevented by the extract. In HacaT cells, B[a]P-UvA increases the frequency of S10P (+38%). When exposure was preceded by extract treatment, the frequency of several methylations was impacted. B[a]P-UvA only induced the expression of SRSF1 and SFPQ in HacaT (+46% and +34%). Treatment with the extract abolished this effect. co-exposure increases the expression of inflammation-related genes (IL-1α, IL-1β) in HacaT cells and decreases those of AQP3, KRT15, and SOd2. The extract has little effect on these changes. In primary fibroblasts, exposure to B[a]P-UvA lowered the expression of LOXL2, LUM, and TGFBR2 (−38%, −59%, and −51%, respectively), and the extract did not affect these modifications. conclusion: Within 24 hours, a single B[a]P-UvA co-exposure changes epigenetic marks of skin cells but has only mild effects on gene expression. An Arundo donax L. extract can prevent part of the epigenetic marks’ changes and could stimulate the expression of some genes in
