Serum miRNA-101 expression signature as non-invasive diagnostic biomarker for Hepatitis C virus-associated hepatocellular carcinoma in Egyptian patients.

Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality globally due to HCC late diagnosis and limited treatment options. MiRNAs (miRNAs) emerged as potential biomarkers for various diseases, including HCC. However, the value of miRNA-101 as a serum biomarker for HCV-induced HCC has not been fully investigated.

Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) is characterized by the accumulation of tau protein in the brain, which forms neurofibrillary tangles and contributes to the gradual deterioration of brain function. As a consequence, cellular senescence occurs, leading to cognitive impairment and hastening the aging process. Immunotherapies targeting Aβ and other protein aggregates are also being developed in the meantime.

Ameliorative effect of venom against arthritic influence of Freund's complete adjuvant FCA in paw and ankle of male rats.

Background: Pain and inflammation are closely associated with rheumatoid arthritis (RA), which affects the bones and joints.

Aim: While there are a number of therapeutic options for arthritis, their side effects restrict their use and encourage the search for alternative, natural remedies.

Methods: In male rats, we examined the anti-inflammatory and anti-arthritic properties of venom (NHV).

How does the coral microbiome mediate its natural host fitness under climate stress conditions? Physiological, molecular, and biochemical mechanisms.

Although the symbiotic partnership between corals and algal endosymbionts has been extensively explored, interactions between corals, their algal endosymbionts and microbial associates are still less understood. Screening the response of natural microbial consortiums inside corals can aid in exploiting them as markers for dysbiosis interactions inside the coral holobiont. The coral microbiome includes archaea, bacteria, fungi, and viruses hypothesized to play a pivotal vital role in coral health and tolerance to heat stress condition via different physiological, biochemical, and molecular mechanisms.

Biochemical properties of immobilized horseradish peroxidase on ceramic and its application in removal of azo dye.

In the current work, electrostatic interactions were used to immobilize the horseradish peroxidase (HRP) onto five types of ceramic materials (C) with different concentrations of oxidized metals (C1-C5). The highest immobilization efficiency (70 and 77%) was detected at 6 mg C3 and 18 enzyme units. Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX) and Fourier Transform Infrared (FTIR) analysis of C3-HRP confirmed the immobilization of the enzyme.

A Low-Cost Workflow to Generate Virtual and Physical Three-Dimensional Models of Cardiac Structures.

Purpose: Three-dimensional modeling and printing (3DMP) of anatomical structures from cross-sectional imaging data can enhance the understanding of spatial relationships in complex congenital heart defects. Partially due to the substantial financial, material and personnel resources required, 3DMP is not yet universally used. Here, we describe a workflow that addresses and eliminates these drawbacks.

Comparative volatiles profiling of two marjoram products via GC-MS analysis in relation to the antioxidant and antibacterial effects.

Marjoram (Origanum majorana L.), also known as "sweet marjoram" or "sweet oregano" is a Mediterranean herbaceous perennial herb cultivated in Egypt and widely consumed as an herbal supplement for treatment of several ailments. The main goal of this study was to assess volatiles' variation in marjoram samples collected from two different widely consumed commercial products using two different extraction techniques viz.

Analysis of salinity-induced metabolome changes in Indian mustard (Brassica juncea) roots and shoots: hydroponic versus microplot cultivation.

Background: Brassica juncea L. (family Brassicaceae) or Indian mustard is a fast-growing oilseed crop. Climate changes mean that it is very important to evaluate the effects of salinity stress on B.

Surgical Treatment of Atrial Septal Defects.

Atrial septal defects (ASDs) are among the most prevalent congenital cardiac malformations. Closure of the defect and repair of associated cardiac malformations are typically indicated if an ASD is hemodynamically significant or symptomatic. This narrative review aims to summarize key aspects of surgical ASD closures.

Sequence-specific interactions determine viscoelasticity and aging dynamics of protein condensates.

Biomolecular condensates are viscoelastic materials. Here, we investigate the determinants of sequence-encoded and age-dependent viscoelasticity of condensates formed by the prion-like low-complexity domain of the protein hnRNP A1 and its designed variants. We find that the dominantly viscous forms of the condensates are metastable Maxwell fluids.

Hyperexcitability precedes CA3 hippocampal neurodegeneration in a dox-regulatable TDP-43 mouse model of ALS-FTD.

Unlabelled: Neuronal hyperexcitability is a hallmark of amyotrophic lateral sclerosis (ALS) but its relationship with the TDP-43 aggregates that comprise the predominant pathology in over 90% of ALS cases remains unclear. Emerging evidence in tissue and slice culture models indicate that TDP-43 pathology induces neuronal hyperexcitability suggesting it may be responsible for the excitotoxicity long believed to be a major driver of ALS neuron death. Here, we characterized hyperexcitability and neurodegeneration in the hippocampus of doxycycline-regulatable rNLS8 mice (NEFH-tTA x tetO-hTDP-43ΔNLS), followed by treatment with AAV encoded DREADDs and anti-seizure medications to measure the effect on behavioral function and neurodegeneration.
