Inhibition of histone methyltransferase G9a aggravates phenotypic severity of hepatic lipotoxicity in non-alcoholic steatohepatitis (NASH).

Lipotoxicity is a key pathological feature in the development of non-alcoholic steatohepatitis (NASH), which is characterized by liver injury, inflammation, and fibrosis. Although lipotoxicity has been shown to induce transcriptomic alterations in liver cells, the specific role of epigenetic regulators in NASH remains elusive. In this study, we demonstrate that pharmacological inhibition of histone methyltransferase G9a significantly worsens NASH progression in mice, as evidenced by increased hepatic cell death, inflammation, and fibrosis.

Distribution of non-thyroid neck swellings and their clinicopathological correlation.

Background: Neck swellings are frequently found and can present the vast pathological spectrum from simple benign to highly malignant, which sometimes can pose a diagnostic dilemma. They are broadly classified as developmental, inflammatory, and neoplastic on the basis of etiology. The aim of the study is to assess the distribution of neck swelling according to etiology and its relation to age groups, as well as to assess their clinicopathological correlation as benign and malignant.

Organosulfur Compounds, S-Allyl-L-Cysteine and S-Ethyl-L-Cysteine, Target PCSK-9/LDL-R-Axis to Ameliorate Cardiovascular, Hepatic, and Metabolic Changes in High Carbohydrate and High Fat Diet-Induced Metabolic Syndrome in Rats.

Metabolic syndrome (MetS) is an ever-evolving set of diseases that poses a serious health risk in many countries worldwide. Existing evidence illustrates that individuals with MetS have a 30%-40% higher chance of acquiring type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), or both. This study was undertaken to uncover the regulatory role of natural organosulfur compounds (OSCs), S-allyl-L-cysteine (SAC), and S-ethyl-L-cysteine (SEC), in targeting high carbohydrate high fat (HCHF)-diet-induced MetS-associated risk management.

Targeting CERS6-AS1/FGFR1 axis as synthetic vulnerability to constrain stromal cells supported proliferation in Mantle cell lymphoma.

The interaction between stromal and tumor cells in tumor microenvironment is a crucial factor in Mantle cell lymphoma (MCL) progression and therapy resistance. We have identified a long non-coding RNA, CERS6-AS1, upregulated in MCL and associated with poor overall survival. CERS6-AS1 expression was elevated in primary MCL within stromal microenvironment and in a subset of MCL cells adhered to stromal layer.

Epidermoid cyst of the midline neck in an 8-year-old girl: A case report.

Epidermoid cysts (ECs) are usually small, benign, keratin-filled cysts, can be congenital or acquired and encountered anywhere in the body. EC and dermoid cyst constitute approximately 7% of all cysts in the head and neck region and tend to occur in areas of embryonic fusion. Neck masses are commonly present in children, and there is often a diagnostic dilemma clinically with common differential diagnoses of this region such as thyroglossal cyst, pre-tracheal lymph nodes, thyroid mass, EC and dermoid cyst.

Role of miRNAs in T-cell activation and Th17/Treg-cell imbalance in acquired aplastic anemia.

Background: Altered T-cell repertoire with an aberrant T-cell activation and imbalance of the Th17/Treg cells has been reported in acquired aplastic anemia (aAA). miRNAs are well known to orchestrate T-cell activation and differentiation, however, their role in aAA is poorly characterized. The study aimed at identifying the profile of miRNAs likely to be involved in T-cell activation and the Th17/Treg-cell imbalance in aAA, to explore newer therapeutic targets.

Cloning, expression, and characterization of a novel thermo-acidophilic l-asparaginase of CSPS4.

In the present investigation, a soil isolate CSPS4 was used for retrieving the l-asparaginase encoding gene () of size 1089 bp. The gene was successfully cloned into the pET28a (+) vector and expressed into BL21() for characterization of the protein. The recombinant rAsn_PA enzyme was purified by affinity chromatography using Ni-NTA resins.

Bone marrow plasma metabonomics of idiopathic acquired aplastic anemia patients using 1H nuclear magnetic resonance spectroscopy.

Introduction: Idiopathic acquired aplastic anemia (AA) is a bone marrow failure disorder where aberrant T-cell functions lead to depletion of hematopoietic stem and progenitor cells in the bone marrow (BM) microenvironment. T-cells undergo metabolic rewiring, which regulates their proliferation and differentiation. Therefore, studying metabolic variation in AA patients may aid us with a better understanding of the T-cell regulatory pathways governed by metabolites and their pathological engagement in the disease.

Targeting Extracellular RNA Mitigates Hepatic Lipotoxicity and Liver Injury in NASH.

Non-alcoholic steatohepatitis (NASH) is a clinically serious stage of non-alcoholic fatty liver disease (NAFLD). Histologically characterized by hepatocyte ballooning, immune cell infiltration, and fibrosis, NASH, at a molecular level, involves lipid-induced hepatocyte death and cytokine production. Currently, there are very few diagnostic biomarkers available to screen for NASH, and no pharmacological intervention is available for its treatment.

Analysis of Immunophenotypic Changes during Ex Vivo Human Erythropoiesis and Its Application in the Study of Normal and Defective Erythropoiesis.

Erythropoiesis is a highly regulated process and undergoes several genotypic and phenotypic changes during differentiation. The phenotypic changes can be evaluated using a combination of cell surface markers expressed at different cellular stages of erythropoiesis using FACS. However, limited studies are available on the in-depth phenotypic characterization of progenitors from human adult hematopoietic stem and progenitor cells (HSPCs) to red blood cells.

Amniotic Fluid Mesenchymal Stromal Cells Derived from Fetuses with Isolated Cardiac Defects Exhibit Decreased Proliferation and Cardiomyogenic Potential.

Amniotic fluid mesenchymal stromal cells (AF-MSCs) represent an autologous cell source to ameliorate congenital heart defects (CHDs) in children. The AF-MSCs, having cardiomyogenic potential and being of fetal origin, may reflect the physiological and pathological changes in the fetal heart during embryogenesis. Hence, the study of defects in the functional properties of these stem cells during fetal heart development will help obtain a better understanding of the cause of neonatal CHDs.

New acute onset of ocular myasthenia gravis after COVID-19 vaccine: A case report.

Reports have shown the association of coronavirus disease 2019 (COVID-19) with several neuromuscular disorders. Myasthenia gravis (MG) is an autoimmune disease in which antibodies bind to acetyl choline receptors in the postsynaptic membrane at the neuromuscular junction. The characteristic clinical feature of the disease is weakness of the ocular muscle, bulbar muscle, and extremity muscles; when the weakness is limited to the ocular muscle only, the condition is known as ocular myasthenia gravis.

Transepidermal elimination of suture material in lip biopsy specimen.

Transepidermal elimination (TE) is a well-known phenomenon by which dermal materials are expelled through an active epithelial-dermal connective tissue interaction. It has been associated with many cutaneous disorders and described as a regular or sporadic occurrence in a variety of dermatologic conditions. TE as a means of expulsion by skin, either externally introduced or endogenously generated foreign material, is well recognized but rarely appreciated phenomenon.

ULK1 inhibition attenuates telomerase activity in hepatic cells.

Autophagy and telomere maintenance are two cellular survival processes that show a strong correlation during human ageing and cancer growth, however, their causal relationship remains unclear. In this study, using an unbiased transcriptomics approach, we uncover a novel role of autophagy genes in regulating telomere extension and maintenance pathways. Concomitantly, the pharmacological inhibition of ULK1 (Unc-51 like autophagy activating kinase 1) attenuated human telomerase reverse transcriptase (hTERT) gene expression and telomerase activity in HepG2 cells.

Extracellular vesicles from bone marrow mesenchymal stromal cells of severe aplastic anemia patients attenuate hematopoietic functions of CD34 hematopoietic stem and progenitor cells.

Mesenchymal stromal cells (MSC) regulate hematopoiesis in the bone marrow (BM) niche and extracellular vesicles (EVs) released by BM-MSC are important mediators of the cross-talk between BM-MSC and hematopoietic stem and progenitor cells (HSPC). We have previously demonstrated that BM-MSC of severe aplastic anemia (SAA) patients have an altered expression of hematopoiesis regulatory molecules. In the present study, we observed that CD34 HSPC when cocultured with BM-MSC EVs from aplastic anemia patients exhibited a significant reduction in colony-forming units (p = .

A New and Highly Sensitive Serum Mannoprotein Lateral Flow Assay for Point-of-Care Diagnosis of Invasive Aspergillosis (Tripathy Method).

Background and objectives The mannoprotein lateral flow assay (MP-LFA) or Aspergillus-specific lateral flow device (AspLFD) is a novel rapid test for point-of-care diagnosis (PoC) of invasive aspergillosis (IA), but its routine clinical application is hampered due to low sensitivity (S) of the assay in serum. Therefore, this study aimed to develop a new method to enhance the S of the serum MP-LFA. Methodology In the new method (Tripathy method), we used direct heating of the serum without any dilution at 120C for 15 minutes to purify the mannoprotein (MP) antigen of the Aspergillus.
