The Neuroprotective Effects of Agmatine on Parkinson's Disease: Focus on Oxidative Stress, Inflammation and Molecular Mechanisms.

Agmatine (AGM), a naturally occurring polyamine derived from L-arginine, has shown significant potential for neuroprotection in Parkinson's Disease (PD) due to its multifaceted biological activities, including antioxidant, anti-inflammatory, and anti-apoptotic effects. This review explores the therapeutic potential of AGM in treating PD, focusing on its neuroprotective mechanisms and evidence from preclinical studies. AGM has been demonstrated to mitigate the neurotoxic effects of rotenone (ROT) by improving motor function, reducing oxidative stress markers, and decreasing levels of pro-inflammatory cytokines in animal models.

Relationship between Modern ART Regimens and Immunosenescence Markers in Patients with Chronic HIV Infection.

The increased life expectancy of PLHIV (People Living with HIV) and the successful highly combined antiretroviral therapy (cART) poses new clinical challenges regarding aging and its co-morbid condition. It is commonly believed that HIV infection "accelerates" aging. Human immunodeficiency virus type 1 (HIV-1) infection is characterized by inflammation and immune activation that persists despite cART, and that may contribute to the development of co-morbid conditions.

Identification and Characterization of Novel Founder Mutations in : Refining the Genetic Landscape of Charcot-Marie-Tooth Disease Type 4D in Bulgaria.

Charcot-Marie-Tooth neuropathy type 4D (CMT4D) is a rare genetic disorder of the peripheral nervous system caused by biallelic mutations in the N-Myc Downstream Regulated 1 gene (). Patients present with an early onset demyelinating peripheral neuropathy causing severe distal muscle weakness and sensory loss, leading to loss of ambulation and progressive sensorineural hearing loss. The disorder was initially described in the Roma community due to a common founder mutation, and only a handful of disease-causing variants have been described in this gene so far.

Rare host variants in ciliary expressed genes contribute to COVID-19 severity in Bulgarian patients.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), a pneumonia with extremely heterogeneous clinical presentation, ranging from asymptomatic to severely ill patients. Previous studies have reported links between the presence of host genetic variants and the outcome of the COVID-19 infection. In our study, we used whole exome sequencing in a cohort of 444 SARS-CoV-2 patients, admitted to hospital in the period October-2020-April-2022, to search for associations between rare pathogenic/potentially pathogenic variants and COVID-19 progression.

Assisted oocyte activation significantly improves zygote formation, cleavage, and implantation rates in patients with a history of fertilization failures.

Background: Fertilization check performed at the 18th hour following classic in vitro fertilization procedure (IVF) or intracytoplasmic sperm injection (ICSI) is a critical stage in assisted reproduction. The success of the treatment is significantly reliant on the quantity of zygotes exhibiting two pronuclei. Consequently, low fertilization rates or complete fertilization failure are highly undesirable outcomes for both patients and reproductive specialists.

Barriers to early diagnosis of chronic kidney disease and use of sodium-glucose cotransporter-2 inhibitors for renal protection: A comprehensive review and call to action.

Chronic kidney disease (CKD) affects approximately 13% of people globally, including 20%-48% with type 2 diabetes (T2D), resulting in significant morbidity, mortality, and healthcare costs. There is an urgent need to increase early screening and intervention for CKD. We are experts in diabetology and nephrology in Central Europe and Israel.

Successful Treatment With High-Dose Colchicine of a 101-Year-Old Patient Diagnosed With COVID-19 After an Emergency Cholecystectomy.

There are multiple factors associated with increased morbidity and mortality in COVID-19 patients, and advanced age is one such independent prognostic factor. It is well established that the multiorgan failure and death in COVID-19 patients are due to the hyperactivation of the NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome and the ensuing cytokine storm. Colchicine, a well-known anti-inflammatory drug, has been shown to inhibit the NLRP3 inflammasome in micromolar concentrations potently.

Colchicine-The Divine Medicine against COVID-19.

Colchicine has a number of effects that suggest it may be useful in the treatment of COVID-19. Myeloid cells are a major source of dysregulated inflammation in COVID-19. The hyperactivation of the NLRP3 inflammasome and the subsequent cytokine storm take place precisely inside them and can lead to multiorgan damage and death.

Effect of Lanthanide Ions and Triazole Ligands on the Molecular Properties, Spectroscopy and Pharmacological Activity.

The effect of La, Ce, Pr and Nd ions on four Ln(ligand) complexes and at three DFT levels of calculation was analyzed. Four ligands were chosen, three of which were based on the 1,2,3-triazole ring. The DFT methods used were B3LYP, CAM-B3LYP and M06-2X.

CYP21A2 Intron 2 Genetic Variants Might Be Associated with the Clinical Characteristics of Women with PCOS.

Aims: Pathogenic variants in the gene are related to the classic and non-classic forms of congenital adrenal hyperplasia (CAH). However, the role of CAH carrier status in the clinical presentation of polycystic ovarian syndrome (PCOS) is still unclear. Moreover, the possible associations of different gene polymorphisms with metabolic and reproductive abnormalities in PCOS have not been investigated.

Clinical and genetic variability among Bulgarian patients with autosomal recessive spastic ataxia of Charlevoix-Saguenay.

Background: Autosomal recessive spastic ataxia ofCharlevoix-Saguenay (ARSACS) is a rare neurodegenerative disorder characterizedby early-onset cerebellar ataxia, peripheral sensorimotor neuropathy, and lowerlimb spasticity. We present clinical andgenetic data of the first Bulgarian patients diagnosed with ARSACS by wholeexome sequencing (WES).

Methods: Variant filtering was performed usinglocally established pipeline and the selected variants were analysed by Sangersequencing.

Intermolecular Electrostatic Interactions in Cytochrome Protein Monolayer on Montmorillonite Alumosilicate Surface: A Positive Cooperative Effect.

Montmorillonite (MM) crystal nanoplates acquire anticancer properties when coated with the mitochondrial protein cytochrome (cytC) due to the cancer cells' capability to phagocytize cytC-MM colloid particles. The introduced exogenous cytC initiates apoptosis: an irreversible cascade of biochemical reactions leading to cell death. In the present research, we investigate the organization of the cytC layer on the MM surface by employing physicochemical and computer methods-microelectrophoresis, static, and electric light scattering-to study cytC adsorption on the MM surface, and protein electrostatics and docking to calculate the local electric potential and Gibbs free energy of interacting protein globules.

Rare Pathogenic Variants in Pooled Whole-Exome Sequencing Data Suggest Hyperammonemia as a Possible Cause of Dementia Not Classified as Alzheimer's Disease or Frontotemporal Dementia.

The genetic bases of Alzheimer's disease (AD) and frontotemporal dementia (FTD) have been comprehensively studied, which is not the case for atypical cases not classified into these diagnoses. In the present study, we aim to contribute to the molecular understanding of the development of non-AD and non-FTD dementia due to hyperammonemia caused by mutations in urea cycle genes. The analysis was performed by pooled whole-exome sequencing (WES) of 90 patients and by searching for rare pathogenic variants in autosomal genes for enzymes or transporters of the urea cycle pathway.

Post-Acute Sequelae of SARS-CoV-2 Infection (PASC) for Patients-3-Year Follow-Up of Patients with Chronic Kidney Disease.

Post-acute sequelae of SARS-CoV-2 (PASC) is a significant health concern, particularly for patients with chronic kidney disease (CKD). This study investigates the long-term outcomes of individuals with CKD who were infected with COVID-19, focusing on their health status over a three-year period post-infection. Data were collected from both CKD and non-CKD patients who survived SARS-CoV-2 infection and were followed for three years as part of a research study on the impact, prognosis, and consequences of COVID-19 infection in CKD patients.
