Exposure of 1800 MHz Radiofrequency with SAR 1,6 W/kg Caused a Significant Reduction in CD4+ T Cells and Release of Cytokines In-Vitro.

Background: Although there have been many studies investigating the effects of electromagnetic fields on humans cells and tissues, the effects of radiofrequency electromagnetic fields exposure on the cells of the immune system are still controversial.

Objective: To investigate the effects of 1800 MHz RF-EMF exposure on peripheral blood mononuclear cells by measuring T helper cells count and the cytokine profile under different conditions of durations and distances.

Methods: The peripheral blood mononuclear cells (PBMCs) from healthy human subjects were exposed to 1800 MHz RF-EMF, with durations of 15, 30, 45, and 60 minutes and distances of 5 and 25 cm.

Comparison between presepsin and procalcitonin in early diagnosis of neonatal sepsis.

Neonatal sepsis remains worldwide one of the leading causes of morbidity and mortality in both term and preterm infants. Lower mortality rates are related to timely diagnostic evaluation and prompt initiation of empiric antibiotic therapy. Blood culture, as gold standard examination for sepsis, has several limitations for early diagnosis, so that sepsis biomarkers could play an important role in this regard.

The Diagnostic Value of Urine Lipoarabinomannan (LAM) Antigen in Childhood Tuberculosis.

Introduction: Diagnosis of Tuberculosis (TB) in children is difficult because the clinical presentation is not specific, the chest X-ray interpretation has low accuracy and sputum sample is difficult to obtain. Antigen detection test such as rapid urine LAM is a non-invasive alternative for diagnosing TB . Lipoarabinomannan (LAM) is the main component of cell wall.
