Transcription Kinetics in the Coronavirus Life Cycle.

Coronaviruses utilize a positive-sense single-strand RNA, functioning simultaneously as mRNA and the genome. An RNA-dependent RNA polymerase (RdRP) plays a dual role in transcribing genes and replicating the genome, making RdRP a critical target in therapies against coronaviruses. This review explores recent advancements in understanding the coronavirus transcription machinery, discusses it within virus infection context, and incorporates kinetic considerations on RdRP activity.

Thyroid disorders in patients with human immunodeficiency virus infection: a meta-analysis.

Background: Thyroid disorders have significant clinical sequelae, including impaired growth in children, metabolic abnormalities, and impaired cognitive function. However, available studies on burden of thyroid diseases in people with human immunodeficiency virus (HIV), particularly its prevalence and its interaction with HIV related factors (like CD4 count), are controversial. This review aimed to provide a comprehensive summary and analysis on the extent of thyroid dysfunctions in this population.

Risk Factors, Associations, and Outcomes of Reduced Fetal Movements: A Preliminary Cross-Sectional Study at Port Sudan Maternity Hospital.

Background: Reduced fetal movements (RFM) are a significant concern in obstetric care. They often indicate fetal distress and are associated with adverse perinatal outcomes such as stillbirth and intrauterine growth restriction (IUGR). While RFM is recognized as a critical marker of fetal well-being, there is a limit to the data available on its risk factors and outcomes in the Port Sudan region.

It discusses innovative solutions for addressing these challenges.

A Relational Approach to the Drivers of Child Acute Malnutrition.

Background: This article presents a new analytical approach to acute malnutrition causal analysis that is different from the orthodox approach in 2 respects. First, it engages with basic causes, that is, beyond the usual focus on individuals and households. Second, it uses a view in the causal analysis.

Seroprevalence and risk factors of brucellosis in dromedary camels () in Sudan from 1980 to 2020: a systematic review and meta-analysis.

Camel brucellosis is a major public health concern in Sudan; however, there is no overall estimation of the prevalence of camel brucellosis in Sudan. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this study aimed to perform a meta-analysis of 30 eligible studies published before December 31, 2022, with a total of 70059 dromedary camels, to estimate the pooled prevalence of camel brucellosis and its risk factors in Sudan. The random effect model was used for the final analysis due to the significantly high heterogeneity among the included studies, and the results showed that the overall pooled prevalence of camel brucellosis was 17%, with a confidence interval (CI) of 12%-21%.

Characterization and risk factors for unexplained female infertility in Sudan: A case-control study.

Background: Female infertility with unknown causes (unexplained) remains one of the mysteries in the reproductive health field, where the diagnostic evidence is still weak and the proposed treatments still work with unknown methods. However, several studies have proposed some possible causes and risk factors for unexplained female infertility.

Aim: To characterize and identify factors associated with unexplained infertility in Sudanese women.

The Different Ecological, Medical, and Industrial Important Bacteria Harboring the Soil of Hail, Kingdom of Saudi Arabia.

This study aims at unraveling the bacterial biodiversity of Hail soil to establish a baseline study that contributes to harnessing these bacteria in applications that benefit human beings. We collected two groups of soil samples; one group of the models contained wheat roots, and the second group was free of roots. Bacteria were isolated from these soils, DNA was extracted, 16srRNA from different isolates was amplified and sequenced, and the phylogeny tree was analyzed.

The role of melatonin in plant growth and metabolism, and its interplay with nitric oxide and auxin in plants under different types of abiotic stress.

Melatonin is a pleiotropic signaling molecule that reduces the adverse effects of abiotic stresses, and enhances the growth and physiological function of many plant species. Several recent studies have demonstrated the pivotal role of melatonin in plant functions, specifically its regulation of crop growth and yield. However, a comprehensive understanding of melatonin, which regulates crop growth and yield under abiotic stress conditions, is not yet available.

First isolation and molecular characterization of canine parvovirus-type 2b (CPV-2b) from red foxes (Vulpes vulpes) living in the wild habitat of Turkey.

A one-year extensive molecular survey on SARS-CoV-2 in companion animals of Turkey shows a lack of evidence for viral circulation in pet dogs and cats.

Current evidence have now demonstrated that SARS-CoV-2 infects a wide array of mammalian animals; however, the full range of hosts and the viral circulation in companion animals remains to be clarified. In this context, as no such evidenced cases have been reported from Turkey, we aimed to screen for SARS-CoV-2 nucleic acid in housed dogs and cats clinically evaluated for respiratory symptoms and reared in different locations of Samsun province in the black sea region of Turkey from July 2020 to July 2021. Nasal swabs were collected from a total of 415 pets (65 cats and 350 dogs) aged between 1 and 9 years old.

Aim: To evaluate the serum leptin levels in Sudanese women and to ascertain the relationship between serum leptin levels and unexplained infertility (UI).

Effects of jasmonic acid in foliar spray and an humic acid amendment to saline soils on forage sorghum plants' growth and antioxidant defense system.

Salinity is one of the primary abiotic stresses that cause negative physiological and biochemical changes due to the oxidative stress caused by the generation of reactive oxygen species (ROS). The effect of jasmonic acid (JA) as foliar spray and humic acid (HA) as soil amendment on the growth and biochemical attributes of forage sorghum plants exposed to salinity stress was investigated. Soil treated with NaCl at levels of 0, 2, and 4 g NaCl kg dry soil (designated as S0, S1, and S2) and soil amendment with humic acid at 0, 3, and 6 g HA kg dry soil (designated as HA0, HA1, and HA2).
