Unlabelled: Magnesium and nickel are ions with an important role in the human body, but their effects are not completely understood.
Aim: To clarify the actions of magnesium and nickel on the rat kidney, which was experimentally treated with retinoic acid, an important therapeutic agent.
Material And Method: The first lot of animals was the witness lot and didn't receive any substance. The second lot received retinoic acid, 50 mg/kg weight/day for 30 days. The third lot received retinoic acid in the same way and magnesium acexamate, 0.5 mEq /kg weight/day for 30 days. The fourth lot received retinoic acid in the same way and NiCl2, 0.5 mEq /kg weight/day for 30 days.
Results: The retinoic acid has a toxic effect on the rat kidney. The magnesium decreases this toxic effect but the nickel increases this toxic effect and destroys some urinary tubes.

Multiorgan proteomic analysis of infected animal models predict potential host factors for chikungunya virus.

Chikungunya virus (CHIKV) is a mosquito-borne alphavirus that is primarily known for causing severe joint and muscle symptoms, but its pathological effects have extended beyond these tissues. In this study, we conducted a comprehensive proteomic analysis across various organs in rodent and nonhuman primate models to investigate CHIKV's impact on organs beyond joints and muscles and to identify key host factors involved in its pathogenesis. Our findings reveal significant species-specific similarities and differences in immune responses and metabolic regulation, with proteins like Interferon-Stimulated Gene 15 (ISG15) and Retinoic Acid-Inducible Gene I (RIG-I) playing crucial roles in the anti-CHIKV defense.

This affords the opportunity to reveal molecular principles that govern the pre-implantation stages of mammalian development. We leveraged a multipurpose allele for acute protein depletion and efficient immunoprecipitation to dissect the molecular functions of the chromatin repressor EHMT2, a candidate antagonist of the mESC-to-2CLC transition.

Combination topical treatments that target multiple acne pathophysiological pathways are more efficacious than topical monotherapies, and simplifying combination treatment by delivering multiple active ingredients as fixed combinations may improve adherence.
Methods: This review provides an overview of efficacy with 4 weeks of treatment in pivotal trials of fixed-combination topical treatments for acne.

Methyltransferase-like 3 (METTL3), the core methyltransferase for -methyladenosine (m6A), plays a crucial role in innate immunity by introducing m6A modifications on viral or host RNAs. Despite its well-established catalytic function in m6A deposition, the broader role of METTL3 in immune regulation remains unclear. Here, we uncovered that EV71 infection enhanced METTL3 expression in interferon (IFN)-deficient Vero and IFN-proficient rhabdomyosarcoma (RD) cells by modulating transcription and post-translational modification, respectively.

Background/aim: Melanoma arises from the uncontrolled multiplication of melanocytes, and poses an escalating global health concern. Despite the importance of early detection and surgical removal for effective treatment, metastatic melanoma poses treatment challenges, with limited options. Among optional therapies, including chemotherapy and immunotherapy, all-trans retinoic acid (ATRA), a natural metabolite of vitamin A, has shown promise in treating melanoma by inducing differentiation, apoptosis, growth arrest, and immune modulation in melanoma cells.
