Disease-Associated Variants in GRIN1, GRIN2A and GRIN2B genes: Insights into NMDA Receptor Structure, Function, and Pathophysiology.

N-methyl-D-aspartate receptors (NMDARs) are a subtype of ionotropic glutamate receptors critical for synaptic transmission and plasticity, and for the development of neural circuits. Rare or de-novo variants in GRIN genes encoding NMDAR subunits have been associated with neurodevelopmental disorders characterized by intellectual disability, developmental delay, autism, schizophrenia, or epilepsy. In recent years, some disease-associated variants in GRIN genes have been characterized using recombinant receptors expressed in non-neuronal cells, and a few variants have also been studied in neuronal preparations or animal models.

Analysis of Surface Expression of NMDAR Subunits in Primary Hippocampal Neurons.

The expression and activity of ionotropic glutamate receptors control signal transduction at the excitatory synapses in the CNS. The NMDAR comprises two obligatory GluN1 subunits and two GluN2 or GluN3 subunits in different combinations. Each GluN subunit consists of four domains: the extracellular amino-terminal and agonist-binding domains, the transmembrane domain, and the intracellular C-terminal domain (CTD).

A Novel Technique for the Management of Persistent Biliary Fistulas Developing After Liver Hydatid Cyst Surgeries: Drain Clamping Technique.

Background: External biliary fistula, where the residual cyst is associated with the biliary tree, is one of the most common complications after liver hydatid cyst surgery. Surgical procedures become a consideration for patients in whom the biliary fistula persists despite all endoscopic procedures. However, reoperation for biliary fistula after hydatid cyst surgery leads to additional complications and increases morbidity and mortality.

Disease-associated nonsense and frame-shift variants resulting in the truncation of the GluN2A or GluN2B C-terminal domain decrease NMDAR surface expression and reduce potentiating effects of neurosteroids.

N-methyl-D-aspartate receptors (NMDARs) play a critical role in normal brain function, and variants in genes encoding NMDAR subunits have been described in individuals with various neuropsychiatric disorders. We have used whole-cell patch-clamp electrophysiology, fluorescence microscopy and in-silico modeling to explore the functional consequences of disease-associated nonsense and frame-shift variants resulting in the truncation of GluN2A or GluN2B C-terminal domain (CTD). This study characterizes variant NMDARs and shows their reduced surface expression and synaptic localization, altered agonist affinity, increased desensitization, and reduced probability of channel opening.

Evaluation of Thiol Disulfide Homeostasis and Ischemia-Modified Albumin Levels as an Indicator of Oxidative Stress in Acne Vulgaris.

Role of Cochlear Nerve Diameter as a Prognostic Indicator for Hearing Recovery in Older Adults with Idiopathic Sudden Sensorineural Hearing Loss.

Background: Idiopathic sudden sensorineural hearing loss is a disabling condition that lowers the quality of life specifically in older adults living alone. It is crucial to determine the outcome of the disease and to offer early treatment to prevent isolation caused by hearing impairment in this population. The objective of our study was to investigate whether the initial cochlear nerve thickness may predict the outcome of hearing recovery in older adults with idiopathic sudden sensorineural hearing loss.

Effects of Androgens on the Thickness of Retinal Layers in Transgender Men and in Women with Polycystic Ovarian Syndrome.

Purpose: This study aimed to evaluate the relationship between androgens and the retinal thickness by comparing the macular thickness (MT), retinal nerve fiber layer (RNFL), and ganglion cell complex (GCC) thickness of female-to-male transgender men (TGM), women with polycystic ovary syndrome (PCOS), and cisgender women (CW).

Methods: Thirty-four eyes of 34 TGM, 34 eyes of 34 women with PCOS, and 45 eyes of 45 CW were evaluated by optical coherence tomography. One-way analysis of variance and body mass index (BMI)-adjusted one-way analysis of covariance were conducted to test the differences between groups for statistical evaluation.

How much is the long-term quality of life impaired in cholecystectomy-related biliary tract injury?

Objectives: Iatrogenic bile duct injury (IBDI) is a serious complication of cholecystectomy that may crucially affect long-term quality of life and have major morbidities. Furthermore, even after reconstructive surgical treatment, such injuries still reduce the long-term quality of life. Therefore, there remains a need to investigate long-term quality of life of the patients since it is considered that there is a long-term decrease in both physical and mental quality of life.

Effects of Pregnanolone Glutamate and Its Metabolites on GABA and NMDA Receptors and Zebrafish Behavior.

Multiple molecular targets have been identified to mediate membrane-delimited and nongenomic effects of natural and synthetic steroids, but the influence of steroid metabolism on neuroactive steroid signaling is not well understood. To begin to address this question, we set out to identify major metabolites of a neuroprotective synthetic steroid 20-oxo-5β-pregnan-3α-yl l-glutamyl 1-ester (pregnanolone glutamate, PAG) and characterize their effects on GABA and NMDA receptors (GABARs, NMDARs) and their influence on zebrafish behavior. Gas chromatography-mass spectrometry was used to assess concentrations of PAG and its metabolites in the hippocampal tissue of juvenile rats following intraperitoneal PAG injection.

The effects of testosterone on transgender males on carotid intima-media thickness and serum inflammatory markers compared within patients with polycystic ovary syndrome.

To evaluate the effects of testosterone on carotid intima-media thickness (CIMT) and serum inflammatory markers compared within transgender males (TGM-Former called female-to-male) and polycystic ovary syndrome (PCOS). The prospective observational study included 30 TGM, 30 patients with PCOS, and 30 healthy women. Groups were compared for CIMT and hematologic inflammatory markers white blood cell (WBC), lymphocyte/monocyte ratio (LMR), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and mean platelet volume (MPV).

Evaluation of erythrocyte membrane fatty-acid compositions in association with interleukin-6 levels in patients with COVID-19.

Objective: The cytokine storm presented in the hyperimmune response is related to poor prognosis in people with COVID-19. Interleukin-6 (IL-6) is one of the most prominent cytokines, especially on mucosal surfaces during infection, causing the cytokine storm. Polyunsaturated fatty acids (PUFAs) are the precursors of eicosanoids, which play critical roles in immune regulation and inflammation.

Evidence for the Association between the Intronic Haplotypes of Ionotropic Glutamate Receptors and First-Episode Schizophrenia.

The heritable component of schizophrenia (SCH) as a polygenic trait is represented by numerous variants from a heterogeneous group of genes each contributing a relatively small effect. Various SNPs have already been found and analyzed in genes encoding the NMDAR subunits. However, less is known about genetic variations of genes encoding the AMPA and kainate receptor subunits.
