Modulation of and Pathways by Hookah Smoke: Implications for Male Reproductive Health.

Antioxidants act by preventing excessive oxidative stress within the developing sperm cells. Hookah smoking has been implicated in inducing oxidative stress which may be a risk factor for male infertility. This study aims to bridge this knowledge gap by evaluating the effect of hookah smoking on sperm quality and the expression of () and 1 () genes which are involved in antioxidant response.

Adverse Effects of Nicotine on Human Sperm Nuclear Proteins.

The effects of smoking on human health have long been documented. However, only a few studies have highlighted the direct effects of nicotine on sperm function. Nicotine, as a chemical compound found in tobacco, has been shown to modulate different aspects of spermatogenesis and sperm functions.

Possible Impact of Human β-defensin 1 on sperm motility in infertile men with abnormal sperm parameters.

Human β-defensins and interleukins may be auxiliary in sperm maturation. This cross-sectional study aimed to evaluate the expression of Human β-defensins 1 and 2, interleukins (ILs)- 10 and -18 genes in sperm, as well as seminal plasma levels of these two cytokines in subfertile men with different types of sperm abnormalities compared to those with normozoospermic men. Participants were separated into two experimental groups: the control group (n = 25) and the group with sperm abnormalities (SA) (n = 45).

Hsa-miR-15b-5p/miR-195-5p Controls Osteogenic Differentiation of Human Adipose-Derived Mesenchymal Stem Cells Through Regulating Indian Hedgehog Expression.

Osteoblastogenesis is regulated by several signaling pathways like hedgehog signaling. Of three types of mammalian Hedgehog genes, the Indian Hedgehog (Ihh) plays an important role in the formation of the skeleton. Mesenchymal stem cells (MSCs) isolated from adipose tissue have been considered a good source of osteoblast differentiation.

The present experimental study was undertaken to investigate the effect of formaldehyde (FA) and curcumin (CUR) on histomorphological features, antioxidant potential, and messenger ribonucleic acid (mRNA) levels of genes related to follicular development in FA-exposed rats. 24 Wistar female rats were divided into four study groups and given intraperitoneal injections of FA (10 mg/kg) ( = 6), FA (10 mg/kg) + CUR (100 mg/kg) ( = 6), sham ( = 6), and control ( = 6) for 14 days. Ovarian follicular histology, the related gene expression, blood factors, and anti/oxidation potentials were assessed using ovarian tissue and serum, respectively.

Possible Harmful Effects of Smoking Hookah on Sperm DNA Fragmentation Index and Protamine Genes Expression in Normozoospermic Men.

Objectives: In recent years, smoking water pipes or hookah has increased among adolescents in most countries. Although there is evidence in support of the negative effects of this type of smoking on human health, such as the increased risk of lung disease, little is known about the potential effects of hookah smoking on the male reproductive system, especially on the molecular aspects of sperm.

Patients And Methods: This cross-sectional study examined sperm DNA fragmentation index, and ) genes expression, and oxidant status in normozoospermic hookah smokers in comparison with non-smoker controls.

Evaluating effect of acrylamide and ascorbic acid on oxidative stress and apoptosis in ovarian tissue of wistar rat.

Acrylamide is one of the undesirable compounds created in food, which leads to oxidative stress. Under normal conditions of the body, there is a balance between the production and elimination of free radicals. Imbalance in this process causes oxidative stress.

ANXA2, SP17, SERPINA5, PRDX2 genes, and sperm DNA fragmentation differentially represented in male partners of infertile couples with normal and abnormal sperm parameters.

This study aims to evaluate the expression of genes associated with the fertilisation potential and embryo development, sperm DNA fragmentation (SDF), and acrosome reaction in male partners of infertile couples with different sperm parameters compared to fertile men. First, male partners of infertile couples with abnormal (N = 25) and normal sperm parameters (N = 25), and fertile men (N = 10) were included in experimental groups I, II, and controls respectively. The mRNA levels of the Annexin A2 (ANXA2), Sperm protein 17 (SP17), Plasma serine protease inhibitor (SERPINA5), and Peroxiredoxin-2 (PRDX2) genes and SDF were evaluated.

Altered methyltransferase gene expression, mitochondrial copy number and 4977-bp common deletion in subfertile men with variable sperm parameters.

Semen parameters have been found to predict reproductive success poorly and are the most prevalent diagnostic tool for male infertility. There are few conflicting reports regarding the correlation of DNMT genes expression, mitochondrial DNA copy number (mtDNAcn) and deletion (mtDNAdel) with different sperm parameters. To investigate DNMT mRNA level, mtDNAcn and deletion in infertile men, with different sperm parameters, compared with fertile men, semen samples from 30 men with unknown male infertility and normal sperm parameters (experimental group I), 30 infertile patients with at least two abnormal sperm parameters (experimental group II) and 30 fertile normozoospermic men (control group) were collected.

Differential apoptotic gene expression in the male partners of infertile couples with normal and abnormal sperm parameters.

Objective: The purpose of this study was to investigate the cellular and molecular levels of apoptosis induction in three groups of male partners of infertile couples, one featuring subjects with normal sperm parameters and unexplained male infertility (UMI), one including men with abnormal sperm parameters, and one with fertile men as controls.

Methods: Twenty-five infertile men with abnormal sperm parameters and 25 men with UMI and normal sperm parameters were recruited as experimental group I and experimental group II; 25 fertile men were included as controls. The mRNA levels of Fas, Fas ligand, Caspase 8, Bax, and Bcl2 were measured in the three groups.

Impact of Vitamin C on Gene Expression Profile of Inflammatory and Anti-Inflammatory Cytokines in the Male Partners of Couples with Recurrent Pregnancy Loss.

This study aimed to evaluate the effect of vitamin C on the expression of inflammatory and anti-inflammatory cytokine genes in the male partners of couples with recurrent pregnancy loss.

Immunopathogenesis of endometriosis: An overview of the role of innate and adaptive immune cells and their mediators.

Background: Endometriosis is a chronic inflammatory disease associated with the growth and proliferation of endometrial-like tissues outside the uterus. Although the exact etiology and mechanism of the pathogenesis of the disease have not been fully elucidated, the immune system cells and the mediators produced by them can be named as effective factors in the onset and progression of the disease.

Aims: We aim to attempt to review studies on the role of the immune system in endometriosis to better understand the pathogenesis of endometriosis.

The serum levels of cytokines were measured on days 0, 15, and 30.

Protective immune response against P32 oncogenic peptide-pulsed PBMCs in mouse models of breast cancer.

High expression of p32 in certain tumors makes it a potential target for immunotherapy. In the present study, the first goal was to design multi-epitope peptides from the P32 protein and the second goal was to compare the prophylactic effects of DCs- and PBMCs- based vaccines by pulsing them with designed peptides. For these purposes, 160 BALB/c mice were vaccinated in 5 different subgroups of each 4 peptides using PBS (F1-4a), F peptides alone (F1-4b), F peptides with CpG-ODN (F1-4c), F peptides with CpGODN and DCs (F1-4d), and F peptides with CpG-ODN and PBMCs (F1-4e).

This study compared the prophylactic effects from vaccines based on dendritic cells (DCs) and peripheral blood mononuclear cells (PBMCs) by pulsing the cells in-vitro with p5 peptide. The different test groups of mice were injected with free peptide or with peptide pulsed with DCs or PBMCs. Two weeks after the last booster dose, immunological tests were performed on splenocyte suspensions from three mice in each group and the remaining mice (5/each group) were evaluated for tumor growth and survival time.

Association between rs1049174 gene polymorphism and idiopathic recurrent spontaneous abortion in Iranian women: a case-control study.

Natural killer group 2, member D () is one of the best known activating receptors of NK cells, which recognises its ligand on altered or stressed cells and activates NK cells to kill them.
