  • Embryo transfer (ET) is being tested in horses to enhance genetic improvement and the study focuses on improving ET success by re-flushing and re-transferring embryos from contaminated to healthy recipient mares.
  • The research involved 25 recipient mares, examining the effectiveness of embryo transfer, with 7 serving as a control group and 18 undergoing treatment to check for infections before transferring embryos.
  • Results showed high rates of endometritis in control mares, leading to embryonic death, while treated mares had a better pregnancy rate, especially in embryos with well-developed capsules, highlighting the importance of monitoring and addressing uterine health.

(1) Background: Aspirin and clopidogrel have been found helpful in improving clinical outcomes among patients with chronic obstructive lung disease (COPD). However, the evidence on the efficacy of aspirin and/or clopidogrel on clinical outcomes has not been synthesized and summarized in the prior reviews. Hence, we undertook a meta-analysis of the research studies examining the effect of aspirin and/or clopidogrel on varying clinical outcomes among COPD patients; (2) Methods: Using key search terms, we searched databases, including MEDLINE, CINAHL, Google Scholar, and EMBASE to find observational studies and RCTs.

Article Synopsis
  • The study investigated the impact of arsenic trioxide and zinc oxide nanoparticles on male reproductive health in adult rats, comparing the effects of these substances alone and in combination with gallic acid as a protective agent.
  • Results showed that exposure led to significant weight and hormonal changes, including reduced testosterone and increased estradiol levels, along with oxidative stress indicators such as elevated malondialdehyde and decreased antioxidant enzymes in the testicular tissues.
  • Gallic acid demonstrated protective effects, improving sperm health and hormonal profiles, and restoring damaged reproductive structures, suggesting it may counteract the negative effects of arsenic and zinc oxide exposure.

Pregnant women have a higher risk of urinary tract infections (UTIs) compared to non-pregnant women, making antibiotics necessary for treatment. However, prescribing antibiotics without culture and sensitivity tests may contribute to antimicrobial resistance. A meta-analysis using R was conducted to determine the prevalence of antibiotic resistance patterns in UTIs among pregnant women.

Background And Objectives: Little is known about the implications of titanium dioxide nanoparticles (TiONPs) and cadmium chloride (Cd) co-exposure on the male reproductive system in mammals. As a result, this study researched the effects of oral TiONPs and/or Cd exposure on male reproduction and testicular functions. Additionally, a mitigation trial with co-enzyme Q10 (CoQ10) has also been conducted.

Background: Literature has reported differences in the epidemiology or natural history of non-communicable diseases among both the male and female sexes. Stratification of multimorbidity burden based on sex is crucial to identify and implement targeted prevention and control interventions for chronic diseases.

Objectives: To determine the burden of hypertension, type-2 diabetes mellitus, and obesity; and to compare the related multimorbidity among male and female patients.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common metabolic disorder affecting more than 400 million individuals worldwide. Being an X-linked disorder, the disease is more common among males than females. Various Arab countries estimated the prevalence of G6PD deficiency; however, findings from different countries have not been synthesized collectively.

Background And Objectives: This study aimed to assess the effect of zinc oxide nanoparticles (ZNPs) and/or arsenic trioxide (ATO) exposure on the liver of adult male Sprague Dawley rats. Moreover, the probable ameliorative impact of gallic acid (GA) against ZNPs and ATO-induced hepatotoxicity and the possible underlying mechanisms were evaluated.

Methods: Sixty male Sprague Dawley rats were distributed into six groups.

Ischaemic mononeuropathy (IMN) is a rarely reported type of peripheral neuropathy secondary to an ischaemic injury, due to a complication of haemodialysis access. Although underreported, this phenomenon typically occurs in diabetic patients and may reflect the predisposition to neuropathic injury on a background of chronic deleterious changes in the microvasculature in diabetes. It is characterised by mononeuropathic features such as paraesthesia, pain and motor weakness and usually is reported as a rare complication of brachiocephalic fistula.

Chemical food preservatives are extensively found in various processed food products in the human environment. Hence, this study aimed to investigate the effect of long-term exposure to five food preservatives (potassium sorbate (PS), butylated hydroxyanisole (BHA), sodium benzoate (SB), calcium propionate (CP), and boric acid (BA)) on the liver and kidney in rats and the probable underlying mechanisms. For 90 days, sixty male albino rats were orally given either water (control), 0.

Introduction: Cigarette smoking is a well-known cancer-causing behavior and a leading cause of death from cancer. However, according to previously published research and meta-analyses, cigarette smoking has a significant inverse association with prostate cancer incidence. Therefore, this study aims to investigate this association based on updated evidence by conducting a systematic review and meta-analysis.

Searching for new compounds with anti-inflammatory properties is a significant target since inflammation is a major cause of pain. A series of pyrazole, imidazopyrazolone, and pyrazolopyrimidine derivatives were designed and synthesized by reaction of 3,5-diamino-1H-pyrazole derivative with cyclic and acyclic carbonyl reagents. The structure of the newly synthesized derivatives were fully characterized using different spectroscopic data and elemental analysis, and therefore, evaluated as COX-2 inhibitors.

The present study was designed to evaluate the probable ameliorative role of quercetin (QCN) against oxidative hepatotoxicity induced by aluminum oxide nanoparticles (AlONPs) with a diameter < 30 nm and lead acetate (Pb) co-exposure in adult male Sprague-Dawley rats. Rats were weighed and allocated to seven groups (n = 10 each) and were treated orally via orogastric gavage for 60 successive days: rats of the 1st group were kept as control given distilled water (1 ml/kg), rats of the 2nd group received 2 ml/kg BW/day corn oil; rats of the 3rd group were administered 20 mg/kg BW QCN/day; rats of the 4th group received 100 mg/kg BW AlONPs; rats of the 5th group received 50 mg/kg BW Pb; rats of the 6th group co-received AlONPs and Pb at the same previous doses; and rats of the 7th group were co-administered AlONPs, Pb, and QCN at the same previous doses. At the end of the experiment, serum levels of alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total, direct, indirect bilirubin, triglycerides, total cholesterol, HDL, VLDL, and LDL were estimated.

Searching for effective and selective anti-inflammatory agents, our study involved designing and synthesizing new pyrazole and pyrazolo[1,5-a]pyrimidine derivatives 4-11. The structures of the synthesized derivatives were confirmed using different spectroscopic techniques. Virtual screening was achieved for the newly designed derivatives using in silico docking simulation inside the active sites of four proteins classified as two cyclooxygenases (COX)-1 (PDB: 3KK6 and 4OIZ) and two COX-2 (PBD: 1CX2 and 3LN1).
