The investigation of the relationship between vitamin D level and severity of diabetic ketoacidosis in new cases of type 1 diabetes in children referred to Hazrat-E- Ali-Asghar Hospital in 2021.

Background And Purpose: According to the role of 25-hydroxyvitamin D (25OHD) in glucose homeostasis and immune modulation, vitamin D deficiency may be associated with type 1 diabetes and diabetic ketoacidosis (DKA). Therefore, this study was conducted with the aim of investigation of the relationship between the vitamin D level and severity of diabetic ketoacidosis in new cases of type 1 diabetes in children referred to Hazrat-E-Ali-Asghar Hospital in 2021.

Methods: The present study is based on a cross-sectional study.

The 4EHP-mediated translational repression of cGAS impedes the host immune response against DNA viruses.

A critical host response against viral infections entails the activation of innate immune signaling that culminates in the production of antiviral proteins. DNA viruses are sensed by the cytosolic pattern recognition receptor cyclic GMP-AMP synthase (cGAS), which initiates a signaling pathway that results in production of proinflammatory cytokines such as Interferon-β (IFN-β) and activation of the antiviral response. Precise regulation of the antiviral innate immune response is required to avoid deleterious effects of its overactivation.

Ribosome Quality Control mitigates the cytotoxicity of ribosome collisions induced by 5-Fluorouracil.

Ribosome quality control (RQC) resolves collided ribosomes, thus preventing their cytotoxic effects. The chemotherapeutic agent 5-Fluorouracil (5FU) is best known for its misincorporation into DNA and inhibition of thymidylate synthase. However, while a major determinant of 5FU's anticancer activity is its misincorporation into RNAs, the mechanisms by which cancer cells overcome the RNA-dependent 5FU toxicity remain ill-defined.

Evaluating the consequences of critically ill patients with pediatric cancer at Aliasghar Children's Hospital.

Background: Despite significant progress in supportive care and advancements in chemotherapy treatments, cancer remains a leading cause of mortality in children. The objective of this study was to assess the potential correlation between various risk factors and the consequences of patients with pediatric cancer who were admitted to the pediatric intensive care unit (PICU).

Methods: The present investigation is a retrospective cohort study that examined children with cancer who were between the ages of 1 month and 17 years and had been admitted to the PICU.

Repression of mRNA translation initiation by GIGYF1 via disrupting the eIF3-eIF4G1 interaction.

Viruses can selectively repress the translation of mRNAs involved in the antiviral response. RNA viruses exploit the Grb10-interacting GYF (glycine-tyrosine-phenylalanine) proteins 2 (GIGYF2) and eukaryotic translation initiation factor 4E (eIF4E) homologous protein 4EHP to selectively repress the translation of transcripts such as , which encodes the antiviral cytokine interferon-β (IFN-β). Herein, we reveal that GIGYF1, a paralog of GIGYF2, robustly represses cellular mRNA translation through a distinct 4EHP-independent mechanism.
