A refined method for high-purity isolation of uterine glandular epithelial cells in mouse.

The uterine endometrium consists of luminal epithelium, glandular epithelium, and stromal cells, with uterine glands playing a pivotal role in pregnancy success among mammals. Uterine glands secrete essential factors that regulate embryo development and implantation; however, their cellular biology remains poorly understood. This study presents a refined method for isolating three distinct endometrial cell types with high purity, with a specific emphasis on glandular epithelial cells.

Experience, Outcomes, and Insights on Endoscopic Colonic Polyp Excision: A Retrospective Cohort Study.

Introduction Colorectal cancer (CRC) continues to pose a major public health challenge, ranking among the most common malignancies globally and being a leading cause of cancer-related mortality. Most CRCs originate from adenomatous polyps, underscoring the importance of detecting and removing these precancerous growths as a key preventive measure against CRC. In particular, large colonic polyps (≥10 mm) warrant special attention due to their increased risk of progressing to malignancy compared to smaller polyps.

The Relationships Between Multidimensional Schizotypy and Metacognitive Beliefs.

There has been a recent surge in schizotypy and metacognition research. Metacognition is an umbrella term for higher-order thought processes. Here, we focussed on maladaptive metacognitive beliefs, which are beliefs related to one's thought processes and often play an important role in the preponderance of psychological disorders.

Oncoproteins E6/E7 of the human papillomavirus types 16 & 18 synergize in modulating oncogenes and tumor suppressor proteins in colorectal cancer.

Objective: Our study presents a novel analysis of the oncogenes and tumor suppressor proteins directly modulated by E6/E7 of high-risk HPV types 16 and 18, in colorectal cancer (CRC).

Effect of obesity on cardiovascular remodeling, and aerobic capacity in adults with coarctation of aorta.

Background: We hypothesized that patients with coarctation of aorta (COA) and obesity would have more advanced cardiovascular remodeling and impaired aerobic capacity compared to COA patients without obesity. The purpose of this study was to assess the relationship between obesity, cardiovascular remodeling, and aerobic capacity in adults with repaired COA.

Method: The study comprised of 3 groups: (1) Obese COA group (n=177) (COA patients with body mass index [BMI] >30 kg/m); (2) Non-obese COA group (n=572) (COA patients with BMI ≤30 kg/m); (3) Control group (n=59) (subjects without structural heart disease and BMI ≤30 kg/m).

Genetic Concordance of Staphylococcus aureus From Oropharyngeal and Sputum Cultures in People With Cystic Fibrosis.

Background: People with cystic fibrosis (CF) may not expectorate sputum at young ages or after they receive CFTR modulators. While oropharyngeal swabs are commonly used to test for lower airway pathogens, it is unknown whether Staphylococcus aureus from the oropharynx matches the strain(s) infecting the lungs. Our goal was to determine whether oropharyngeal and sputum isolates of S.

Safety of crushed/chewed P2Y12 inhibitors in acute coronary syndromes - a meta-analysis of randomized controlled trials.

The administration of crushed or chewed P2Y12 inhibitors (P2Y12i) allows faster platelet inhibition in patients presenting acute coronary syndrome (ACS). Whether this administration approach is safe needs further analysis. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing chewed/crushed to integral P2Y12i administration in patients with ACS.

Arabic translation and validation of the clinician administered Staden schizophrenia anxiety rating scale (S-SARS).

Background: Research on anxiety in patients with schizophrenia of Arab origin is surprisingly scarce, particularly given that expressions of both psychotic disorders and anxiety disorders can be largely shaped by cultural factors. This study proposes to complement previous research by exploring the psychometric characteristics of an Arabic translation of the Staden Schizophrenia Anxiety Rating Scale (S-SARS) in chronic, remitted patients diagnosed with schizophrenia. As the Arabic version of the Generalized Anxiety Disorder 7-Item Scale (GAD-7) has not been previously validated in Arabic in patients with schizophrenia, this study had as a secondary aim to investigate the psychometric properties of this scale before its use.

Nematicidal Potentiality of Four Marine Molluscans' Defensive Secretions From the Red Sea Against Syphacia obvelata (Nematoda: Oxyuridae) In Vitro.

The continuous requirement to substitute safe and affordable alternatives for helminth medications, as well as address the resistance of some used drug classes, introduced bioactive products derived from marine animals into the field of competition; however, almost all the previous research only focused on their impact on bacterial and protozoal infection. In the present work, we investigated the potential in vitro nematocidal effect of the aqueous extract of defense secretions for four species of marine mollusks: two cephalopods, namely the cuttlefish Sepia pharaonis and the common Octopus Octopus vulagris and two gastropods, the sea hare Aplysia argus and the sea slug Berthillina citrina, against the adult murine pinworm Syphacia obvelata. Data showed dose and time efficacy in all examined extracts.

Interaction of High- and Low-Risk Human Papillomavirus Genotypes is Associated with a Reduced Risk of Developing Cervical Cancer.

Introduction: Cervical cancer is among the most common types of cancer in women and is associated with human papillomavirus (HPV) infection. The association between cervical cancer and high-risk HPV infection has been well documented. However, the effect of simultaneous infection with high- and low-risk HPV or low-risk HPV alone on the risk of developing cervical malignancy remains unanswered in guidelines.
