Hybrid-based framework for COVID-19 prediction via federated machine learning models.

The COronaVIrus Disease 2019 (COVID-19) pandemic is unfortunately highly transmissible across the people. In order to detect and track the suspected COVID-19 infected people and consequently limit the pandemic spread, this paper entails a framework integrating the machine learning (ML), cloud, fog, and Internet of Things (IoT) technologies to propose a novel smart COVID-19 disease monitoring and prognosis system. The proposal leverages the IoT devices that collect streaming data from both medical (e.

Lack of association between C3123A polymorphism of the angiotensin II type 2 receptor gene and hypertension in Tunisian population.

Background: Hypertension is a polygenic disease. Various singlenucleotide gene polymorphisms of renin angiotensin system have been explored in hypertension. Angiotensin II, the major biologically active component of this system, exerts its effect via two pharmacologically distinct subtypes of angiotensin II receptors, the angiotensin II type 1 receptor and the angiotensin II type 2 receptor.

Plasma homocysteine in schizophrenia: determinants and clinical correlations in Tunisian patients free from antipsychotics.

The existence of association between hyperhomocysteinaemia (HHC) and schizophrenia has been suggested by several recent studies. This study aimed to determine the prevalence of HHC and its main determinants, and sought a correlation with clinical features in Tunisian patients with schizophrenia. Plasma homocysteine (Hcy), folate, and vitamin B12, as well as the C677T methylene tetrahydrofolate reductase (MTHFR) polymorphism, were studied in 33 patients with schizophrenia, all free from antipsychotic treatment, and 35 age- and smoking-habit-matched healthy subjects as controls.
