RESUMO
Background and Objectives: To investigate the effect of infection with human papillomavirus (HPV) or Chlamydia trachomatis (CT) and HPV + CT coinfection on sperm quality, inflammation, and the state of oxidative stress (OS) in asymptomatic infertile men. Materials and Methods: Semen samples from 84 asymptomatic military infertile men were studied. The polymerase chain reaction (PCR) was used for the molecular detection of HPV and CT. Semen parameters were analyzed according to the World Health Organization guidelines. Inflammation was evaluated by an IL-1ß, IL-6, and IFN-γ enzyme-linked immunosorbent assay (ELISA) and OS by the quantification of lipid peroxidation (LPO), 8-hydroxydeoxyguanosine (8-OHdG), and total antioxidant capacity (TAC). Results: A total of 81 of the 84 (96.4%) samples were positives for the pathogens, with 55/81 (68%) being positive for HPV, 11/81 (13.5%) for CT, and 15/81 (18.5%) for HPV + CT coinfection. Seminal parameters were affected in the infected groups, including pH increases above the normal range in all groups. An abnormal sperm morphology was observed in the HPV and HPV + CT groups. Higher cytokine levels were detected in the HPV group and the highest IL-1ß level was found in the HPV + CT group. No cytokines were detected in the CT group. High LPO and 8-OHdG levels were found in all groups with a lower TAC. Comparisons between groups showed the highest OS state was observed in the HPV group. Conclusions: High HPV infection or coinfection (HVP + CT) in these infertile men suggest compromising male fertility by inducing a proinflammatory state and OS. Infection with CT suggests an alteration of the state of OS by promoting an alkaline pH.

BACKGROUND: Some studies have suggested the efficacy of homeopathic treatment for irritable bowel syndrome (IBS). OBJECTIVE: The aim of this pilot study was to evaluate the efficacy of individualized homeopathic treatment in patients with IBS. METHODS: The study was carried out at the National Homeopathic Hospital of the Secretary of Health, Mexico City, Mexico and included 41 patients: 3 men and 38 women, mean age 54 ± 14.89 years, diagnosed with IBS as defined by the Rome IV Diagnostic criteria. Single individualized medicine was prescribed for each patient, taking into account all presenting symptoms, clinical history, and personality via repertorization using RADAR Homeopathic Software (archibel, Isnes, Belgium). The homeopathic drugs were used at fifty-millesimal (LM) potency per the Mexican Homeopathic Pharmacopoeia starting with 0/1 and increasing every month (0/2, 0/3, 0/6). Severity scales were applied at the beginning of treatment and every month for 4 months of treatment. The evaluation was based on comparing symptom severity scales during treatment. RESULTS: The results demonstrated that 100% of patients showed some improvement and 63% showed major improvement or were cured. The study showed a significant decrease in severity of symptom scores 3 months after treatment, with the pain score showing a decrease 1 month after treatment. The results highlight the importance of individualized medicine regimens using LM potency, although the early decrease in pain observed could also be due to the fact that Lycopodium clavatum and Nux vomica were the main homeopathic medicine prescribed, and these medicines contain many types of alkaloids, which have shown significant analgesic effects on pain caused by physical and chemical stimulation. CONCLUSION: This pilot study suggests that individualized homeopathic treatment using LM potencies benefits patients with IBS.

OBJECTIVE: The purpose of the current study was to evaluate the modulation of Calcitonin gene-related peptide (CGRP) associated to the efficacy of Electroacupuncture (EA) in the reduction of climacteric symptoms. METHODS: Nine women between 51 and 59 years old with climacteric syndrome in menopause or perimenopause were included. Patients with hormone replacement therapy, psychiatric treatment with antidepressants, or acupuncture treatment in the last 3 months were excluded. A 4 Hz EA treatment was performed at acupoints Shenshu (BL-23), Pishu (BL-20), Guanyuan (REN-4), Taixi (KID-3), Fuliu (KID-7), Sanyinjiao (SP-6) and Neiguan (P-6) points. Women were treated two times a week for five consecutive weeks for a total treatment of 10 sessions. The menopause rating scale (MRS) was used to evaluate symptoms reduction and CGRP gene expression was measured before and after 10 EA session. RESULTS: The results shown that climacteric symptoms diminish significantly after EA therapy. CGRP gene expression was down-regulated, evidencing a decrease of 5-fold after EA therapy respect to the initial condition. CONCLUSION: EA treatment was associated with improvement in patients with climacteric syndrome and may be related to modulation of CGRP levels.

The aim of this study was to evaluate the association between prostate cancer (PCa) and Human papillomavirus (HPV) infection in the Mexican population. We studied 356 paraffin-embedded tissues from unrelated Mexican men with PCa or benign prostatic hyperplasia (BPH), with the latter serving as control. HPV detection was performed by polymerase chain reaction (PCR) using universal primers, and viral genotypes were detected using sequencing or multiplex PCR. Light microscopy analyses enabled the identification of koilocytes in samples subsequently analyzed for HPV detection by in situ PCR and for p16-INK4A expression by immunohistochemistry. The results showed that high risk- (HR) HPVs were detected in 37/189 (19.6%) PCa specimens compared to 16/167 (9.6%) of BHP specimens (odds ratio 2.3; 95% CI= 1.2 to 4.3; p=0.01). These data suggest HR-HPV may play a role in PCa. HPV 52 and 58 were the most frequent genotypes (33 and 17%, respectively) detected in the population studied. Koilocytes were detected in all in situ PCR-HPV-positive samples, representing a pathognomonic feature of infection, and we observed the overexpression of p16-INK4A in HPV-positive samples compared to HPV-negative samples, indirectly suggesting the presence of HR-HPV E7 oncoprotein. These results suggest that HPV infection plays an important role in prostate cancer development.
RESUMO
Programmed cell death (PCD) is induced in Entamoeba histolytica by a variety of stimuli in vitro and in vivo. In mammals, intracellular acidification serves as a global switch for inactivating cellular processes and initiates molecular mechanisms implicated in the destruction of the genome. In contrast, intracellular alkalinization produced by P-glycoprotein overexpression in multidrug-resistant cells has been related to apoptosis resistance. Our previous studies showed that overexpression of E. histolytica P-glycoprotein (PGP) altered chloride-dependent currents and triggered trophozoite swelling, the reverse process of cell shrinkage produced during PCD. Here we showed that antisense inhibition of PGP expression produced a synchronous death of trophozoites and the enhancement of biochemical and morphological characteristics of PCD induced by G418. The nucleus was contracted, and the nuclear membrane was disrupted. Moreover, chromatin was extensively fragmented. Ca(2+) concentration was increased, while the intracellular pH (ipH) was acidified. In contrast, PGP overexpression prevented intracellular acidification and circumvented the apoptotic effect of G418.
