Background: The Japanese quail () is a small migratory bird whose main habitats are located in East Asia, Russia, China, Japan, Korea, and India. The Japanese quail was first introduced into the Iraqi research sector in the early 1980s. This investigation aimed to identify the genetic divergence between the available genetic lines of the Japanese quail in Iraq as a first step to conducting further conservation and breeding, benefiting from studying the genetic diversity related to productivity, adaptation, and immune susceptibility.

The Putative Antilipogenic Role of NRG4 and ERBB4: First Expression Study on Human Liver Samples.

Front Biosci (Landmark Ed)

December 2024

Center for Immunology and Cellular Biotechnology, Institute of Medicine and Life Sciences, Immanuel Kant Baltic Federal University, 236001 Kaliningrad, Russia.

Background: Epidermal growth factor receptor 4 (ERBB4) and neuregulin 4 (NRG4) have been shown to reduce steatosis and prevent the development of non-alcoholic steatohepatitis in mouse models, but little to nothing is known about their role in non-alcoholic fatty liver disease (NAFLD) in humans. This study is the first to investigate the expression of and mRNAs and their role in lipid metabolism in the livers of individuals with obesity, type 2 diabetes and biopsy-proven NAFLD.

Methods: Liver biospecimens were obtained intraoperatively from 80 individuals.

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.

Background: There is a growing interest in exploring the biological characteristics of nanoparticles and exploring their potential applications. However, there is still a lack of research into the potential genotoxicity of fullerene derivatives and their impact on gene expression in human cells. In this study, we investigated the effects of a water-soluble fullerene derivative, C60[C6H4SCH2COOK]5H (F1), on human embryonic lung fibroblasts (HELF).

Background: Long-term use of levodopa, a metabolic precursor of dopamine (DA) for alleviation of motor symptoms in Parkinson's disease (PD), can cause a serious side effect known as levodopa-induced dyskinesia (LID). With the development of LID, high-frequency gamma oscillations (~100 Hz) are registered in the motor cortex (MCx) in patients with PD and rats with experimental PD. Studying alterations in the activity within major components of motor networks during transition from levodopa-off state to dyskinesia can provide useful information about their contribution to the development of abnormal gamma oscillations and LID.

Cortical spreading depolarization (CSD), a slowly propagating wave of transient cellular depolarization, is a reliable cortical response to various brain insults (stroke, trauma, seizures) and underlying mechanism of migraine aura. Little is known about CSD effects on brain network activity. Using undirected (mutual information, MI) and directed (transfer entropy, TE) measures, we studied the dynamics of cross-hemispheric connectivity associated with the development of unilateral CSD in freely behaving rats and the involvement of inhibitory transmission in mechanisms of the coupling changes.

Atherosclerosis is a chronic inflammatory disease affecting the vascular system, characterised by the accumulation of modified lipoproteins, immune cell aggregation and the development of fibrous tissue within blood vessel walls. As atherosclerosis impacts blood vessels, its adverse effects may manifest across various tissues and organs. In this review, we examine the association of atherosclerosis with Alzheimer's disease, stroke, pancreatic and thyroid dysfunction, kidney stones and chronic kidney diseases.

Bird eggs can be spherical, ellipsoid, ovoid, or pear-shaped (pyriform), the latter being the most complex. There is however no unambiguous evolutionary/adaptive explanation for this final, exotic shape. We hypothesized that pyriform eggs have a larger surface area-to-volume ratio (S/V) that may be a criterion for increased embryo metabolism.

It has recently become evident that the de novo emergence of genes is widespread and documented for a variety of organisms. De novo genes frequently emerge in proximity to existing genes, forming gene overlaps. Here, we present an analysis of the evolutionary history of a putative de novo gene, lawc, which overlaps with the conserved Trf2 gene, which encodes a general transcription factor in Drosophila melanogaster.

Background And Aims: Gastroesophageal reflux disease (GERD) is widespread in the population and is characterized by the risk of developing Barrett's esophagus and associated adenocarcinoma. Key factors in the progression of the disease are not only the frequency and duration of reflux episodes, but also the resistance of the esophageal mucosa to aggressive reflux molecules. Assessment of the state of tight junction proteins, the rate of their recovery under the influence of various treatment regimens is an urgent task for choosing optimal approaches to curing patients with GERD.

Ultrastructural disturbances in microglia-neuron interactions in the head of the caudate nucleus in schizophrenia.

Eur Arch Psychiatry Clin Neurosci

December 2024

Laboratory of Clinical Neuropathology, Mental Health Research Center, Kashirskoe Shosse 34, 115522, Moscow, Russia.

Previously we found altered microglia-neuron interactions in the prefrontal cortex in schizophrenia. We hypothesized that microglia-neuron interactions may be dysregulated in the caudate nucleus in schizophrenia. A postmortem ultrastructural morphometric study was performed to investigate satellite microglia (SatMg) and adjacent neurons in the head of the caudate nucleus in 21 cases of schizophrenia and 20 healthy controls.

The Kuril Islands are located in the Far-East of Russia and enriched with shallow and terrestrial hot springs. Prokaryotic diversity of Kuril geothermal environments has been studied fragmentarily and mainly by culture-dependent methods. We performed the first large-scale investigation of microbial communities, inhabited more than 30 terrestrial hot springs of Kunashir and Iturup Islands, analyzed by 16S rRNA gene fragment amplicon sequencing, together with chemical analysis of thermal waters and sediments.

Atrial fibrillation (AF) and heart failure (HF) often accompany each other, as they share similar risk factors and pathophysiological mechanisms. AF in patients with HF is known to increase hospitalizations and worsen prognosis. A combination of AF and HF translates into high risks of thromboembolic complications, which renders anticoagulants an important aspect of therapy for these patients.

The article is devoted to a form of botulism that has been little studied in our country and is registered exclusively in infants. The fundamental difference between this form and the most common foodborne botulism is that infants become infected by ingestion of spores, followed by their germination, colonization of the intestines and production of botulinum toxin , which leads to the development of life-threatening flaccid paralysis. Taking into account the peculiarities of pathogenesis, the clinical manifestations of infant botulism have some features, which are discussed by the authors.

The trend of an annual increase in the detection of new cases of osteoarthritis (OA) and an increase in the number of patients with chronic lower back pain (LBP) calls for the search for new drugs and pharmaconutraceuticals with anti-inflammatory and chondroprotective properties. In 2019, approaches to the treatment of pain in OA significantly changed. In international and Russian clinical guidelines (CG), pharmaconutraceutical chondroitin sulfate (CS) and glucosamine sulfate (GS) are recommended for OA of different localization as a basic therapy.

At the present stage, great progress has been achieved in understanding the mechanisms of the development of cerebral ischemia. This became possible due to the achievements of theoretical disciplines, in connection with which the general biological approach was formed in the study of pathogenesis of acute and chronic cerebrovascular disorders (CVD). The discovery of pathways of free radical oxidation in cerebral ischemia made it possible to substantiate and develop therapeutic strategies using drugs with antioxidant and neuroprotective activity.
