Introduction: The grading of glial tumors is based on morphological and sometimes on molecular features. Many markers have been assessed in order to grade the glial tumours without a real consensus. Some authors reported that SRSF1, a spiling factor, presents an expression correlated to the tumours grades.

The CD28 IVS3 + 17 T/C polymorphism and the GVHD occurrence in Tunisian patients receiving an HLA-identical sibling HSCs transplant.

Graft-versus-host disease (GVHD) is a potentially serious complication ofallogeneic hematopoietic stem cell transplantation (HSCT). Graft-contaminating T cells (donor T cells) arecrucial for the development ofGVHD since they are able to react against the recipient's antigens. In this study we aim toevaluatethepotentialassociation between the IVS3 + 17 T/C gene variation in the CD28 molecule, a T cells costimulatory factor, and the GVHD occurrence in a Tunisian group of recipients of allo-HSCTs.

Introduction: Sleep quality is a complex phenomenon with quantitative and subjective aspects that vary during adolescence. The prevalence of sleep disorders is not known in Tunisia due to the lack of validated tools.

Aim: To translate and validate the questionnaire Pittsburgh Sleep Quality Index (PSQI) into Tunisian Arabic in middle school students.

Introduction: Mini Clinical Evaluation Exercise (mini-CEX) is one of the assessment tools in medical education. It includes three steps: overview of clinical situation, observation and feedback.

Aim: To evaluate the feasibility of mini-CEX as a formative assessment tool for medical trainees in 5th year of medicine in a teaching intensive care unit (ICU).

Cutaneous manifestations of COVID-19 among healthcare workers: A Case report and literature review.

Common clinical features of COVID-19 are increasingly known but cutaneous manifestations are rarely described among healthcare workers. A review of cutaneous manifestations of COVID-19 especially among healthcare workers (HCW) is thus required. The aim of our current study was to provide a comprehensive review of cutaneous manifestations of COVID-19 among HCW through six case reports and a literature review.

A new cobalt(ii) -porphyrin: synthesis, characterization, electric properties and application in the catalytic degradation of dyes.

In this work, a new porphyrin, 5,10,15,20-tetrakis{4-[((4-methoxyphenyl)acetyl)oxy]phenyl}porphyrin (HTMAPP) (1), and its cobalt complex [Co(TMAPP)] (2) were synthesized in good and quantitative yields, respectively. The chemical structures of these synthesized compounds were confirmed by FT-IR, H NMR, MS, UV-visible, and fluorescence spectroscopy. Their photophysical properties, namely their molar extinction coefficients (), fluorescence quantum yields ( ) and lifetimes ( ), were determined and compared with those of -tetraphenylporphyrin.

New Markers of Bone Fragility in Hemodialysis Patients: A Monocentric Study.

Introduction: Mechanisms underlying bone fragility in patients under dialysis are various. The assessment of bone disorder is not yet codified in these patients. Our study aimed to determine the relationship between the serum fibroblast growth factor 23 (FGF23) level and bone fragility.

Gastrointestinal bleeding as an initial manifestation of gastric lipoma: Case report and review of the literature.

Gastric lipoma should be considered as a rare differential diagnosis in patients presenting with gastrointestinal bleeding. Diagnosis is mainly done by radiologic and endoscopic findings. It presents characteristic pathognomonic endoscopic signs.
