Background: Previously, we reported lower RSK4 mRNA and protein levels in malignant ovarian tumors compared to normal and benign ovarian tissues. Also, we observed a significant inverse correlation between the advanced ovarian cancer stages and RSK4 mRNA levels. We did not investigate the mechanisms involved in RSK4-reduced expression in ovarian cancer.

Background: Patients' lack of knowledge about their own disease may function as a barrier to shared decision-making and well-being. This study aimed to evaluate the impact of written educational materials on breast cancer patients.
Methods: This multicenter, parallel, unblinded, randomized trial included Latin American women aged ≥18 years with a recent breast cancer diagnosis yet to start systemic therapy.

Current medical guidelines consider pregnant women with COVID-19 to be a high-risk group. Since physiological gestation downregulates the immunological response to maintain "maternal-fetal tolerance", SARS-CoV-2 infection may constitute a potentially threatening condition to both the mother and the fetus. To establish the immune profile in pregnant COVID-19+ patients, a cross-sectional study was conducted.

The CatSper channel localizes exclusively in the flagella of sperm cells. The Catsper1 protein, together with three pore units, is essential for the CatSper Channel formation, which produces flagellum hyperactivation and confers sperm fertility. expression is dependent on Sox transcription factors, which can recognize in vitro at least three Sox binding sites on the promoter.

Objective: The role that Beclin 1 (BECN1) plays in the development and progression of cancer mediated by autophagy, as well as its differential expression in breast cancer cell lines and mammary tumor tissue according to the molecular subtype, has been demonstrated. The objective of this study was to evaluate the association of BECN1 cytoplasmic expression with clinical and pathologic response, recurrence, disease-free survival (DFS) and overall survival (OS) in patients with locally advanced breast cancer (LABC), according to immunophenotype.
Patients And Methods: 64 patients with non-triple negative LABC and 20 patients with triple negative LABC who received preoperative chemotherapy were included in an observational, analytical and retrospective study to evaluate the cytoplasmic expression of BECN1 protein by immunohistochemistry in microarrays of breast cancer tissue obtained before treatment.

Although there are currently several factors that allow measuring the risk of having breast cancer or predicting its progression, the underlying causes of this malignancy have remained unknown. Several molecular studies have described some mechanisms involved in the progress of breast cancer. These have helped in identifying new targets with therapeutic potential.

Urinary tract infections (UTI) during pregnancy are frequently associated with hypertensive disorders, increasing the risk of perinatal morbidity. Calcitriol, vitamin D's most active metabolite, has been involved in blood pressure regulation and prevention of UTIs, partially through modulating vasoactive peptides and antimicrobial peptides, like cathelicidin. However, nothing is known regarding the interplay between placental calcitriol, cathelicidin, and maternal blood pressure in UTI-complicated pregnancies.

During coronavirus disease 2019 (COVID-19) pandemic, efforts have been made to rethink the health system and provide various recommendations to the best care of patients and for the protection of health personnel. In patients with suspicion or confirmation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who require surgical intervention and anesthetic management, strategies must be established to minimize aerosol-generating procedures. Regional anesthesia (RA) is not considered an aerosol-generating procedure per se and is currently proposed such as a safe strategy and part of comprehensive perioperative care.

Objective: Multiple factors are involved in the physiology and variability of postsurgical pain, a great part of which can be explained by genetic and environmental factors and their interaction. Epigenetics refers to the mechanism by which the environment alters the stability and expression of genes. We conducted a scoping review to examine the available evidence in both animal models and clinical studies on epigenetic mechanisms involved in the regulation of postsurgical and chronic postsurgical pain.

Objective: BIK and GRP78 have shown differential expression profiles in breast cancer (BC) tissue, in addition to its important participation in the pathophysiology of cancer. The purpose of this study was to evaluate the association of BIK and GRP78 protein expression with clinical and pathologic response to preoperative chemotherapy, recurrence, disease-free survival (DFS) and overall survival (OS), in patients with BC.
Material And Methods: Fifty-three patients who received preoperative chemotherapy where included in an observational, analytical and retrospective study to assess the BIK and GRP78 protein expression by immunohistochemistry in microarrays of BC tissue obtained before treatment.

Problem: Immune responses of fetal membranes involve the production of chemoattractant mediators causing infiltration of maternal and fetal leukocytes, intrauterine inflammation and potentially the disruption of maternal-fetal tolerance. Prolactin (PRL) has deep immunoregulatory effects in the fetal-maternal interface. We aimed to test the in vitro PRL effect upon chemotactic capacities of human fetal membranes.

Perfluorohexane sulfonate (PFHxS) is one of the most abundant perfluorinated compounds in the environment. Exposure to this compound has been correlated to a decrease in human fertility, although the molecular and cellular mechanisms underlying this correlation have not been described. The adverse reproductive effects of PFHxS could be based on alterations in oocyte maturation, the process rendering oocytes competent for fertilization.

Blau syndrome (BS) is a rare, chronic autoinflammatory disease with onset before age 4 and mainly characterised by granulomatous arthritis, recurrent uveitis, and skin rash. Sporadic (also known as early-onset sarcoidosis) or familial BS is caused by gain-of-function mutations in the gene, which encodes for a multi-task protein that plays a crucial role in the innate immune defense. We report on three Mexican patients clinically diagnosed with BS who exhibited a likely pathogenic variant in as revealed by whole-exome sequencing (WES) and Sanger sequencing: two variants (c.
