Eusociality, characterized by reproductive division of labor, cooperative brood care, and multi-generational cohabitation, represents a pinnacle of complex social evolution, most notably manifested within the Hymenoptera order including bees, ants, and wasps. The molecular underpinnings underlying these sophisticated social structures remain an enigma, with noncoding RNAs (ncRNAs) emerging as crucial regulatory players. This article delves into the roles of ncRNAs in exerting epigenetic control during the development and maintenance of Hymenopteran eusociality.

This review explores the intricate relationship between glaucoma and circadian rhythm disturbances. As a principal organ for photic signal reception and transduction, the eye plays a pivotal role in coordinating the body's circadian rhythms through specialized retinal ganglion cells (RGCs), particularly intrinsically photosensitive RGCs (ipRGCs). These cells are critical in transmitting light signals to the suprachiasmatic nucleus (SCN), the central circadian clock that synchronizes physiological processes to the 24-hour light-dark cycle.

Light environment in the Arctic differs widely with the seasons. Studies of relationships between objectively measured circadian phase and amplitude of light exposure and melatonin in community-dwelling Arctic residents are lacking. This investigation combines cross-sectional (n = 24-62) and longitudinal (n = 13-27) data from week-long actigraphy (with light sensor), 24-h salivary melatonin profiles, and proxies of metabolic health.

Creutzfeldt-Jakob disease (CJD) is a classic representative of the group of prion diseases and is characterized by progressive degeneration of the structures of the nervous system with a variety of neurological symptoms, steady progression and inevitable death. The disease is based on a change in the tertiary structure of the protein, which leads to disruption of the normal functioning of cells. Despite the fact that the etiology and pathogenesis of CJD are now well studied, intravital diagnosis of this serious disease remains difficult due to the peculiarities of the pathological process (unusually long incubation period, variety of clinical symptoms), the lack of pathognomonic markers that make it possible to make a diagnosis with a high degree of confidence, and also insufficient awareness of medical workers.

The RNA-binding S1 domain is a β-barrel with a highly conserved RNA-binding site on its surface. This domain is an important part of the structures of different bacterial, archaeal, and eukaryotic proteins. A distinctive feature of the S1 domain is multiple presences (structural repeats) in proteins and protein complexes.

The adenomas in Cushing's disease frequently exhibit mutations in exon 14, within a binding motif for the regulatory protein 14-3-3 located between the catalytic domain (DUB), responsible for ubiquitin hydrolysis, and the WW-like domain that mediates autoinhibition, resulting in constantly active USP8. The exact molecular mechanism of deubiquitinase activity disruption in Cushing's disease remains unclear. To address this, Sanger sequencing of was performed to identify mutations in corticotropinomas.

Background And Aim: Diabetes has been shown in last decades to be associated with a significantly higher mortality among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary PCI (PPCI). Therefore, the aim of current study was to evaluate the impact of diabetes on times delays, reperfusion and mortality in a contemporary STEMI population undergoing PPCI, including treatment during the COVID pandemic.

Methods And Results: The ISACS-STEMI COVID-19 is a large-scale retrospective multicenter registry involving PPCI centers from Europe, Latin America, South-East Asia and North-Africa, including patients treated from 1st of March until June 30, 2019 and 2020.

Article Synopsis
  • The ring rot of potato, caused by a bacterial pathogen, is a quarantine disease that threatens the global potato industry, making its detection crucial for control efforts.
  • A new detection system combines CRISPR/Cas13a with NASBA for identifying viable bacteria in potato tubers, allowing for both instrumental and visual detection methods.
  • The system shows a limit of detection as low as 1000 RNA copies per reaction and can be performed in under 2 hours, potentially serving as a routine on-site testing method.

Epilepsy is a brain disorder characterized by a persistent predisposition to epileptic seizures. With various etiologies of epilepsy, a significant proportion of patients develop pharmacoresistance to antiepileptic drugs, which necessitates the search for new therapeutic methods, in particular, using gene therapy. This review discusses the use of adeno-associated viral (AAV) vectors in gene therapy for epilepsy, emphasizing their advantages, such as high efficiency of neuronal tissue transduction and low immunogenicity/cytotoxicity.

In addition to tumor imaging, advanced high-tech PET/CT imaging is increasingly used to elucidate the underlying causes of fever of unknown origin caused by various inflammatory processes, including pyelonephritis. Two clinical cases of whole-body PET/CT with 18F-FDG glucose, which allowed to visualize the molecular and cellular features of acute pyelonephritis as the cause of fever of unknown origin, are presented in the article. The scientifically based mechanisms of this process and the reliability of the results are discussed.

The study aimed to develop a methodological framework to identify forest ecosystems affected by wildfires and evaluate their recovery chronologically. To do this remote sensing analysis, sites with burn scars were selected based on various criteria (fire severity, affected area, vegetation and soil type, slope, aspect, and one-time occurrence of wildfire in the last 23 years). Spectral vegetation indices (VIs) from satellite imagery were used to estimate burn severity and vegetation cover changes.
