Preliminary findings on the absence of PEPITEM release in B cells isolated from Saudi donors: implications for expanded population studies.

Background: Adiponectin (AQ) plays a role in regulating immune responses. Previous research indicates that B cells can affect T cell transmigration via the adiponectin-induced peptide PEPITEM in Caucasians. This study explores whether this mechanism is also applicable to Saudi populations, considering potential ethnic variations in immune response.

Bone marrow mesenchymal stem cells expressing Neat-1, Hotair-1, miR-21, miR-644, and miR-144 subsided cyclophosphamide-induced ovarian insufficiency by remodeling the IGF-1-kisspeptin system, ovarian apoptosis, and angiogenesis.

Ovarian insufficiency is one of the common reproductive disorders affecting women with limited therapeutic aids. Mesenchymal stem cells have been investigated in such disorders before yet, the exact mechanism of MSCs in ovarian regeneration regarding their epigenetic regulation remains elusive. The current study is to investigate the role of the bone marrow-derived mesenchymal stem cells (BM-MSCs) lncRNA (Neat-1 and Hotair1) and miRNA (mir-21-5p, mir-144-5p, and mir-664-5p) in mitigating ovarian granulosa cell apoptosis as well as searching BM-MSCs in altering the expression of ovarian and hypothalamic IGF-1 - kisspeptin system in connection to HPG axis in a cyclophosphamide-induced ovarian failure rat model.

Role of fenofibrate in multiple sclerosis.

Multiple sclerosis (MS) is the most frequent inflammatory and demyelinating disease of the central nervous system (CNS). The underlying pathophysiology of MS is the destruction of myelin sheath by immune cells. The formation of myelin plaques, inflammation, and injury of neuronal myelin sheath characterizes its neuropathology.

PEPITEM Treatment Ameliorates EAE in Mice by Reducing CNS Inflammation, Leukocyte Infiltration, Demyelination, and Proinflammatory Cytokine Production.

To investigate the effect of the therapeutic treatment of the immunopeptide, peptide inhibitor of trans-endothelial migration (PEPITEM) on the severity of disease in a mouse model of experimental autoimmune encephalomyelitis (EAE) as a model for human multiple sclerosis (MS), a series of experiments were conducted. Using C57BL/6 female mice, we dosed the PEPITEM in the EAE model via IP after observing the first sign of inflammation. The disease was induced using MOG35-55 and complete Freund's adjuvants augmented with pertussis toxin.

BM-MSCs alleviate diabetic nephropathy in male rats by regulating ER stress, oxidative stress, inflammation, and apoptotic pathways.

Diabetic nephropathy (DN), a chronic kidney disease, is a major cause of end-stage kidney disease worldwide. Mesenchymal stem cells (MSCs) have become a promising option to mitigate several diabetic complications. In this study, we evaluated the therapeutic potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) in a rat model of STZ-induced DN.

Breast Milk Mesenchymal Stem Cells and/or Derived Exosomes Mitigated Adenine-Induced Nephropathy via Modulating Renal Autophagy and Fibrotic Signaling Pathways and Their Epigenetic Regulations.

Chronic kidney disease (CKD), a global health concern, is highly prevalent among adults. Presently, there are limited therapeutic options to restore kidney function. This study aimed to investigate the therapeutic potential of breast milk mesenchymal stem cells (Br-MSCs) and their derived exosomes in CKD.

Clinical Characteristics and Risk Factors among Patients with Positive COVID-19 Test Admitted to ICU.

Background: Studies that show common characteristics among ICU-admitted patients due to COVID-19 are available on the net, but such studies in Saudi Arabia are limited.

Methods: A descriptive cross-sectional study establishing common comorbidities and risk factors among critically ill patients who tested positive for COVID-19 at the National Guard Hospital from March 2, 2020, to March 20, 2021. The data were obtained from the BEST Care System of King Abdulaziz Medical City, computed, and analyzed using SPSS.

Mesenchymal stem cell therapy: A review of clinical trials for multiple sclerosis.

Multiple sclerosis (MS) is a disease of the central nervous system (CNS) that is the result of the body's own immune cells being auto-reactive to the myelin regions of the body as if these regions were foreign antigens. This demyelination process is damaging to the electrical conductivity of neurons. The current medicines are only capable of fighting off the symptoms of the disease, but not the disease itself.

Epstein-Barr Virus (EBV) and Multiple Sclerosis Disease: A Biomedical Diagnosis.

Multiple sclerosis (MS) is a degenerative disease that affects 2.8 million people worldwide. It is a central nervous system disease (CNS), in which the myelin sheath covering the brain and spinal cord neurons is attacked.

Awareness of Medical Students toward Circadian Rhythm and Sleep Disorder Based on Biomedical Diagnosis.

Background: Sleep disorders affect an individual's mental and physical health and vice versa. Sleep medicine is underrecognized as a specialty; therefore, many sleep disorders go undiagnosed. This study is aimed at assessing the knowledge of medical students toward circadian neuroscience and sleep disorder based on biomedical diagnosis.

Prevalence and Correlation of Metabolic Syndrome in Patients with Bipolar Disorder in NGHA, Riyadh.

Background: Metabolic syndrome is considered dangerous, especially to patients that are diagnosed with a mental condition such as bipolar disorder, since these types of patients can be difficult to deal with. Metabolic syndrome can lead to multiple cardiovascular diseases, strokes, and diabetes. A careful approach is important when it comes to facing a complex condition such as this.

Assessment of the Knowledge Level of First Aid among Medical Students in Work Environment.

First aid is one of the most important life-saving skills a health provider specifically or anybody generally must have. It can be defined as the first treatment one provides at the site of the accident to the injured person until full medical treatment is available. In some emergency situations, simple first aid can make a life-or-death difference.

COVID-19 and the role of stem cells.

There is currently an ongoing coronavirus respiratory disease (COVID-19) pandemic that is caused by SARS-CoV-2 virus, which emerged out of Wuhan, China. In severe cases, the disease can progress to respiratory distress, hypoxia, and multi-organ failure, all of which are associated with high mortality. Mesenchymal stem cells (MSCs) possess potent and broad-ranging immunomodulatory activities.

Exposure to cell phones reduces heart rate variability in both normal-weight and obese normotensive medical students.

Background: We investigated and compared the effect of the radiofrequency electromagnetic field (RF-EM) emitted by a cell phone on the electrocardiogram and heart rate variability (HRV) of normotensive normal-weight and obese medical students.

Method: Twenty medical student volunteers, normal weight (age = 23 ± 2, BMI = 23.05 ± 1.

The influence of intra-alveolar application of honey versus Chlorhexidine rinse on the incidence of Alveolar Osteitis following molar teeth extraction. A randomized clinical parallel trial.

Background: Alveolar Osteitis (AO) is a complication occurs on the post-extraction days that includes pain and disintegrated blood clot. Chlorhexidine (CHX) rinse after extraction is an effective method for decreasing the incidence of AO. Honey has natural antibacterial properties and effectiveness when it is used as a dressing on burns and wounds.

Comparative adhesive and migratory properties of mesenchymal stem cells from different tissues.

Background: Mesenchymal stem cells (MSC) are used in therapy, often by injection into the blood.

Objective: We aimed to compare the adhesive and migratory properties of MSC from umbilical cords (UCMSC), bone marrow (BMMSC) or trabecular bone (TBMSC), which might influence delivery to injured tissue.

Methods: MSC were perfused through glass capillaries coated with matrix proteins, collagen or fibronectin, or albumin.

Origin-Specific Adhesive Interactions of Mesenchymal Stem Cells with Platelets Influence Their Behavior After Infusion.

We investigated the adhesive behavior of mesenchymal stem cells (MSC) in blood, which might influence their fate when infused as therapy. Isolated human bone marrow MSC (BMMSC) or umbilical cord MSC (UCMSC) adhered efficiently from flow to the matrix proteins, collagen, or fibronectin, but did not adhere to endothelial selectins. However, when suspended in blood, BMMSC no longer adhered to collagen, while UCMSC adhered along with many aggregated platelets.
