Is serum endocan a sensitive biomarker for early recurrence of hepatocellular carcinoma after radiofrequency ablation?

Background And Aim Of The Work: Hepatocellular cancer (HCC) is one of the common liver cancers and considered to be the sixth most commonly occurring cancer in the world and the second leading cause of death among cancer patients. More recent studies on HCC showed that the elevated serum endocan level was a predictive factor of recurrence after radiofrequency ablation. The aim of this study is to evaluate the serum endocan level as a prognostic biomarker for recurrence of HCC after percutaneous radiofrequency ablation.

Results of low-level laser therapy in the treatment of hair growth: An Egyptian experience.

Recently, low level laser therapy was evaluated as an effective stimulating hair growth. Hair loss is the most common complaint in dermatology (specially females). It causes a significant psychosocial distress and decreased quality of life in affected patients and exists in different types, but the most common types are androgenetic alopecia and telogen effluvium (TE).

Optimizing of the Cementitious Composite Matrix by Addition of Steel Wool Fibers (Chopped) Based on Physical and Mechanical Analysis.

The demand for durable, resistant, and high-strength structural material has led to the use of fibers as reinforcing elements. This paper presents an investigation into the inclusion of chopped steel wool fibers (CSWFs) in cement to form a high-flexural strength cementitious composite matrix (CCM). CSWFs were used as the primary reinforcement in CCM at increments of 0.

Intermittent Lipopolysaccharide Exposure Significantly Increases Cortical Infarct Size and Impairs Autophagy.

Globally, stroke is a leading cause of death and disability. Traditional risk factors like hypertension, diabetes, and obesity do not fully account for all stroke cases. Recent infection is regarded as changes in systemic immune signaling, which can increase thrombosis formation and other stroke risk factors.

Glucosuric, renal and haemodynamic effects of licogliflozin, a dual inhibitor of sodium-glucose co-transporter-1 and sodium-glucose co-transporter-2, in patients with chronic kidney disease: A randomized trial.

Aim: To investigate the glucosuric, renal and haemodynamic effects of licogliflozin, a dual sodium-glucose co-transporter-1 and sodium-glucose co-transporter-2 inhibitor, in patients with chronic kidney disease (CKD).

Methods: This multiple-dose, parallel-group, phase II mechanistic study randomized 53 participants (aged 18-78 years, body mass index ≤ 50 kg/m ) with varying degrees of CKD or normal renal function to treatment with licogliflozin (50 mg once daily) or placebo for 7 days. The effects of licogliflozin on 24-h urinary glucose excretion (UGE ), renal function, haemodynamics, pharmacokinetics and safety were assessed.

Gasdermin D restricts Burkholderia cenocepacia infection in vitro and in vivo.

Burkholderia cenocepacia (B. cenocepacia) is an opportunistic bacterium; causing severe life threatening systemic infections in immunocompromised individuals including cystic fibrosis patients. The lack of gasdermin D (GSDMD) protects mice against endotoxin lipopolysaccharide (LPS) shock.

Insights Into Mucosal Innate Immune Responses in House Dust Mite-Mediated Allergic Asthma.

The prevalence of asthma has been rising steadily for several decades, and continues to be a major public health and global economic burden due to both direct and indirect costs. Asthma is defined as chronic heterogeneous inflammatory diseases characterized by airway obstruction, mucus production and bronchospasm. Different endotypes of asthma are being recognized based on the distinct pathophysiology, genetic predisposition, age, prognosis, and response to remedies.

Defective immunometabolism pathways in cystic fibrosis macrophages.

Background: Mitochondria play a key role in immune defense pathways, particularly for macrophages. We and others have previously demonstrated that cystic fibrosis (CF) macrophages exhibit weak autophagy activity and exacerbated inflammatory responses. Previous studies have revealed that mitochondria are defective in CF epithelial cells, but to date, the connection between defective mitochondrial function and CF macrophage immune dysregulation has not been fully elucidated.

Discovery of novel pyrazolo[3,4-b]pyridine scaffold-based derivatives as potential PIM-1 kinase inhibitors in breast cancer MCF-7 cells.
