Addition of Mitoquinone (MitoQ) to Fresh Human Sperm Enhances Sperm Motility without Attenuating Viability.

The preparation of human sperm in an andrology laboratory subjects it to oxidative stress. Reactive oxygen species are produced by mitochondria, making it susceptible to oxidative damage; hence, mitochondria-targeted antioxidants like Mitoquinone (MitoQ) might have therapeutic potential for oxidative-damage-associated disorders. The current research aims to establish whether MitoQ has any positive effects during in vitro preparation of fresh human sperm.

General pattern of paediatric poisoning in Jordan during 2018-2019.

Introduction: Acute accidental poisoning in children remains a significant public health issue and a predictable cause of morbidity around the world. To take preventive measures, it is necessary to identify the pattern of this problem.

Objective: To determine the extent and characteristics of paediatric poisoning, an epidemiological investigation specific to each country is required.

Characterization of BCL-X L , MCL-1, and BAX Protein Expression in Response to Neoadjuvant Chemotherapy in Breast Cancer.

The use of chemotherapy has improved the overall treatment of breast cancer, which is frequently administered in the form of neoadjuvant chemotherapy (NAC). Apoptosis is an established cell stress response to NAC in preclinical models; however, there is limited understanding of its role in clinical cancer, specifically, its contribution to favorable pathologic responses in breast cancer therapy. Here, we aimed to characterize the change in protein expression of 3 apoptosis-associated biomarkers, namely, BCL-X L , MCL-1, and BAX in breast cancer in response to NAC.

Investigating the Utility of the SOFA Score and Creating a Modified SOFA Score for Predicting Mortality in the Intensive Care Units in a Tertiary Hospital in Jordan.

Background: The utility of the Sequential Organ Failure Assessment (SOFA) score in predicting mortality in the intensive care unit (ICU) has been demonstrated before, but serial testing in various settings is required to validate and improve the score. This study examined the utility of the SOFA score in predicting mortality in Jordanian ICU patients and aimed to find a modified score that required fewer laboratory tests.

Methods: A prospective observational study was conducted at Jordan University Hospital (JUH).

Non-Dexamethasone Corticosteroid Therapy's Effect on COVID-19 Prognosis in Cancer Patients: A Retrospective Study.

Background: Anti-inflammatory corticosteroids are used in cancer treatment and COVID-19 infections. Data on the impact of non-dexamethasone corticosteroids on COVID-19 infection severity in cancer patients are minimal. This study investigates if corticosteroid treatment affects the disease severity in adult cancer patients.

The Effect of Dexamethasone Treatment on COVID-19 Prognosis in Cancer Patients.

Background: Dexamethasone is used to treat cancer, relieve chemotherapy-induced nausea and vomiting, enhance cancer patients’ appetites, and treat COVID-19 patients. There is little evidence of the impact of a dexamethasone treatment plan on the severity of COVID-19 infections in cancer patients. This study explores whether dexamethasone treatment plan influences the severity of COVID-19 in dexamethasone-treated cancer patients.

Androgen downregulates desmocollin-2 in association with induction of mesenchymal transition of breast MDA-MB-453 cancer cells.

Desmosomes are cellular structures that are critical in cell-cell adhesion and in maintaining tissue architecture. Changes in the expression of desmocollin-2 (DSC2) have been noted during tumor progression into an invasive phenotype and as cells undergo epithelial-mesenchymal transition. We have previously reported that breast MDA-MB-453 cancer cells, a luminal androgen receptor (AR) model of triple-negative breast cancer, acquire mesenchymal features when treated with the AR agonist, dihydrotestosterone (DHT).

PD-L1 Expression Is a Favorable Prognostic Marker in Gastric Carcinoma.

Gastric cancer (GC) is the fifth most common cancer and the third leading cause of cancer-related mortality worldwide. Although multidisciplinary therapeutic strategies have improved treatment outcomes, the overall prognosis for patients with GC remains poor. Recently, immunotherapeutic agents targeting immunosuppressive proteins such as anti-programmed death-1 receptor and anti-programmed death ligand-1 (PD-L1) have emerged as effective treatment options for various cancers, including GC.

Application of Gas Chromatography-Mass Spectrometry for the Identification and Quantitation of Three Common Synthetic Cannabinoids in Seized Materials from the Jordanian Market.

Synthetic cannabinoids (SCs) were developed to mimic the effects of Δ-tetrahydrocannabinol on humans. SCs were distributed in the form of herbal blends, with smoking being the main method of consumption. These synthetic compounds have a wide range of physical, behavioral, and harmful effects on the body.

Association between occupational lead exposure and plasma levels of selected oxidative stress related parameters in Jordanian automobile workers.

Objectives: To study any possible correlation between blood lead levels and some oxidative stress parameters of selected groups of lead-exposed automobile occupational Jordanian workers.

Material And Methods: Blood lead levels were determined for a total of 90 male automobile workers aged within the range of 25-45 years old along with the group of 20 agematched healthy males control. To get an idea about the antioxidant status of controls and lead-exposed workers, and to estimate the oxidative stress caused by exposure to lead, we measured the hydrogen peroxide (HO) concentration, superoxide dismutase (SOD) activity, lipid peroxidation as malondialdehyde (MDA) and total antioxidant capacity of controls and workers.

Low Incidence of the DPD IVS14+1G>A Polymorphism in Jordanian Breast and Colorectal Cancer patients.

Background: Dihydropyrimidine dehydrogenase (DPD) is a crucial enzyme in the catabolism of 5-fluorouracil (5-FU), a drug that is frequently used in cancer therapy. Patients with deficient DPD activity are at risk of developing severe 5-FU–associated toxicity. One possible cause of deficiency is genetic polymorphisms in the DPD gene, such as IVS14+1G>A.

Histomorphometric Alterations Induced in the Testicular Tissues by Variable Sizes of Silver Nanoparticles.

OBJECTIVE: To investigate the histomorphometric alterations induced in testicular tissues by variable sizes of silver nanoparticles (SNPs). STUDY DESIGN: Male mice (BALB/C) were treated with SNPs (1 mg/kg) using 5 different sizes (10, 20, 40, 60, and 100 nm) for 35 days. Testicular biopsies from all mice under study were examined histomorphologically.

Occupational exposure to pesticides and occurrence of the chromosomal translocation t(14;18) among farmers in Jordan.

Background: An increased incidence of non-Hodgkin's lymphoma (NHL) has been reported in farmers and other occupational groups working with pesticides. In these individuals, an increased prevalence of the chromosomal translocation t(14;18)(q32;q21), one of the most common chromosomal abnormalities in NHL, has been detected in peripheral blood lymphocytes. This translocation juxtaposes the antiapoptotic BCL2 protein to the immunoglobulin heavy chain gene locus (IGH) leading to overexpression of BCL2.
