The abdominal seatbelt sign is well described in the literature as an indicative of intra-abdominal visceral injuries; it is considered rare because it is difficult to detect with no single observation providing reliable diagnosis. Consequently, it often presages a delayed diagnosis. We here report lessons from management of 44 year-old man professional driver, victim of a road traffic accident who underwent a damage control laparotomy and whose abdominal seatbelt sign was diagnosed late.

• Thoracolumbal hyposgastric Necrotizing fasciitis (TLHNF) of dental origin is exceptional. • A 32 year-old male farmer with no particular history of pathology presented with a dental pain for 3 weeks with an automedicationof an association of diclofenac / paracetamol. Throrought clinical and laboratory examination results demonstrated a TLHNF of dental origin.

Objective: This study was aimed at examining the vulnerability of Central Africa to the COVID-19 pandemic.

Methods: Demographic, health, and socio-economic indicators were used to describe the vulnerability. The study period was from December 31st, 2019 to May 31st, 2020 (i.

Several studies have shown that low levels of adiponectin (ADP) and high levels of alpha tumor necrosis factor (NFT) increase the risk or severity of many cardiometabolic diseases associated with insulin resistance. The main objective of this study was to evaluate the association between plasma adipokines and IR measured by HOMA-IR. The secondary objective was to determine the biomarker of the potential inflammation to predict IR in Congolese melanoderm subjects residing in Brazzaville.

Glioblastoma (GBM) is the most common and malignant astrocytic glioma, accounting for about 90% of all brain tumors with poor prognosis. Despite recent advances in understanding molecular mechanisms of oncogenesis and the improved neuroimaging technologies, surgery, and adjuvant treatments, the clinical prognosis of patients with GBM remains persistently unfavorable. The signaling pathways and the regulation of growth factors of glioblastoma cells are very abnormal.

A decrease in mass of isografts and a decline in islet function are major challenges in islet transplantations. Despite this, transplantation of 84 h harvested pancreatic duct ligation (PDL) tissues have been shown to have the same functional ability to foetal pancreata, but there was only 40% success in reverting hyperglycaemia. We tested the potential of early islets with mesenchymal stromal cells (MSCs) to promote isogeneic grafts survival and to restore normoglycemia in diabetic rats, in comparison with late islets.

Background/aim: We calculated the homeostatic model assessment (HOMA) for estimating insulin sensitivity and beta-cell function in normal, healthy nondiabetics with infections (malaria, influenza, HIV, Helicobacter pylori, Chlamydia pneumoniae, and hepatitis C virus), type 2 diabetic black patients, and healthy controls from Kinshasa, DR Congo. Materials and methods: A case-control study was carried out between 2006 and 2007 for black Central African participants managed for HOMA.Results: In total, 219 patients and 110 healthy controls were matched for sex and age.

The islet, the endocrine portion of the pancreas - develops from an invagination of the pancreatic duct epithelial cells (PDECs) into the surrounding tissue. The contact of the PDECs with mesenchymal cells (MSCs) may be an essential drive for endocrine cell fate. During pancreatic development, cells that express Neurogenin-3 (Ngn3) biomarker are precursors of insulin- producing beta cells.

The International Diabetes Federation predicts that, over the next twenty years, the largest increase in the prevalence of diabetes will be in the Africa region. Recognizing an unmet need for more focus on Africa and engagement with African scholars, the Islet Society held its 6th annual meeting July 20-21, 2014 in Stellenbosch, South Africa. Here, we present a report that covers the presentations and discussion points from that meeting.

Background: The pregnancy rate during in-vitro fertilization (IVF) following progesterone supplement still remains very low at around 20%.

Objective: To investigate the effects of peanut oil itself on the endometrial receptivity, the pregnancy success rate and fertility during the peri-implantation time in hyper stimulated and normal rats.

Materials And Methods: Thirty-six adult Sprague Dawley rats with at least four regular oestrus cycles were randomly divided into 4 groups: two groups were hyper stimulated by human chorionic gonadotropin (hCG) and treated with progesterone or with peanut oil; the two other groups were not hyper stimulated and treated with saline solution or peanut oil.
