Mesenchymal stem cells improve cardiac function in diabetic rats by reducing cardiac injury biomarkers and downregulating JAK/STAT/iNOS and iNOS/Apoptosis signaling pathways.

Cardiovascular complications are prevalent manifestations of type 2 diabetes mellitus (T2DM) and are usually the main cause of death. This study aims to show the underlying mechanisms of the potential therapeutic effect of mesenchymal stem cells (MSCs) on diabetic cardiac dysfunction. Twenty-four male Wistar rats were randomly assigned to one of three groups The control group received standard laboratory chow, and the groups with T2DM received a single dose of 45 mg/kg body weight of streptozotocin (STZ) after 3 weeks of pretreatment with a high-fat diet (HFD).

Nutrient patterns and risk of diabetes mellitus type 2: a case-control study.

Backgrounds: Although the significance of diet in preventing or managing diabetes complications is highlighted in current literature, there is insufficient evidence regarding the correlation between nutrient patterns and these complications. The objective of this case-control study is to investigate this relationship by analyzing the dietary intake of nutrients in participants with and without type 2 diabetes (T2D).

Methods: A case-control study was conducted at the Tabriz Center of Metabolism and Endocrinology to investigate the relationship between nutrient patterns and type 2 diabetes (T2D).

Nuts as a Part of Dietary Strategy to Improve Metabolic Biomarkers: A Narrative Review.

Background: Nuts are in the spotlight because of their association with improved health outcomes. We aimed to summarize the findings of previous studies to evaluate the impact of nuts consumption on glycaemic and lipid profile, inflammation, and oxidative stress.

Methods: Electronic searches for observational and intervention studies were undertaken in PubMed, Embase, Web of Science, and Science Direct until 2022 for searching the studies aiming the application of different types of nuts and the beneficial effects of nuts in improving glycemia, dyslipidemia, inflammation, and oxidative stress.

Molecular and Clinical Aspects of COVID-19 Vaccines and Other Therapeutic Interventions Apropos Emerging Variants of Concern.

Coronavirus disease 2019 (COVID-19) has overwhelmed the healthcare and economy of the world, with emerging new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) posing an everlasting threat to humanity. While most COVID-19 vaccines provide adequate protective immunological response against the original SARS-CoV-2 variant, there is a pressing need to understand their biological and clinical responses. Recent evidence suggests that some of the new variants of SARS-CoV-2 evade the protection conferred by the existing vaccines, which may impede the ongoing efforts to expedite the vaccination programs worldwide.

Raised plasma insulin level and homeostasis model assessment (HOMA) score in cerebral malaria: evidence for insulin resistance and marker of virulence.

Objective: To study the glycaemic profile of patients with severe malaria (SM).

Methods: For this purpose, 110 SM patients were recruited. Pre-treatment random blood glucose and plasma insulin were measured in a subset of donors.

The profile of IgG-antibody response against merozoite surface proteins 1 and 2 in severe Plasmodium falciparum malaria in Eastern Sudan.

In this study, antibodies (Ab) directed against three MSP antigens; MSP1(19), MSP2(A), and MSP2(B) were analyzed in blood samples obtained from 223 Sudanese patients who presented with either severe malaria (SM) or uncomplicated malaria (UM) and from 117 malaria-free donors (MF). The results showed that the prevalence of MSP Abs was associated with the clinical outcome of malaria infection, and the Ab prevalence was age-dependent (P<0.0005).

Allelic polymorphism of MSP2 gene in severe P. falciparum malaria in an area of low and seasonal transmission.

The severe malaria (SM) and uncomplicated malaria (UM) infections are expected to have different genetic makeup. In this study, blood samples were obtained from 325 donors with SM and UM and malaria-free donors (including asymptomatic submicroscopic malaria--ASUM), from Eastern Sudan. The SM group included patients with cerebral malaria (CM), severe malarial anemia (SMA), and other complications.

Genetic fingerprints of parasites causing severe malaria in a setting of low transmission in Sudan.

In this study we intended to examine the extent of genetic diversity of Plasmodium falciparum parasites causing severe malaria (SM). For this purpose, 100 parasite isolates were obtained from patients with SM and uncomplicated malaria, from an area of low and unstable malaria transmission in Sudan. The diversity of infection (DOI) was estimated by relating the number of the different parasite genotypes that were detected to the total number of parasites that were genotyped (parasite population/subpopulation).

Drug resistance-virulence relationship in Plasmodium falciparum causing severe malaria in an area of seasonal and unstable transmission.

The pathogenesis of severe Plasmodium falciparum malaria is still obscure, but is believed to be multi-factorial, and among the important factors are intrinsic parasite-properties. Here we investigated the association between clinical manifestation of P. falciparum malaria (an indicator of virulence) and two parasite properties--drug resistance and gametocyte production.

Differential induction of immunoglobulin G to Plasmodium falciparum variant surface antigens during the transmission season in Daraweesh, Sudan.

Background: The acquisition of immunoglobulin (Ig) G to variant surface antigens (VSAs) seems important for the development of protective immunity against malaria. Unlike VSAs expressed by parasite isolates associated with uncomplicated malaria, VSAs expressed by parasite isolates associated with severe malaria (VSA(SM)) are frequently recognized by IgG.

Methods: We analyzed levels of anti-VSA IgG in 57 individuals in Daraweesh, Sudan, before and after the transmission season.

Cerebral malaria is frequently associated with latent parasitemia among the semi-immune population of eastern Sudan.

The accurate diagnosis of malaria starts with clinical suspicion, confirmed by reliable laboratory results. A hospital-based study, described here, was carried out in a malaria mesoendemic area in eastern Sudan, where the inhabitants are semi-immune to malaria, and the fever threshold of parasitemia is not above the detection level of microscopy. Thus, we hypothesized that patients with symptoms highly suggestive of cerebral malaria (CM), but aparasitemic by microscopy, may have submicroscopic parasitemia.
