Increased MASH-associated liver cancer in younger demographics.

Background: The incidence of cancer and the prevalence of metabolic disease and metabolic dysfunction-associated steatotic liver disease is increasing in young adults. However, updated global data on metabolic dysfunction-associated steatohepatitis (MASH)-associated primary liver cancer (PLC) in young adults remains scarce.

Methods: This study analyzed data from the Global Burden of Disease study between 2000 and 2021 to assess the age-standardized incidence, mortality, and disability-adjusted life years rates from MASH-associated PLC in young adults (15-49 y).

End Column Reverse Chromatography as a Novel Approach for Enhanced Separation: A Pilot Study.

Background: Currently, the most popular technique in gas chromatography (GC) is the "temperature programming", where the temperature increases from the start of the injection. This leads to faster elution of analytes compared to isothermal methods. However, isothermal methods are considered optimal for separating compounds with similar retention times.

Postoperative Spinal Cord Ischemia Monitoring: A Review of Techniques Available after Endovascular Aortic Repair.

Background: Spinal cord ischemia is one of the complications that can occur after open and endovascular thoracoabdominal aortic repair. This occurs despite various perioperative approaches, including distal aortic perfusion, hybrid procedures with extra anatomical bypasses, motor-evoked potential, and cerebrospinal fluid drainage. The inability to recognize spinal ischemia in a timely manner remains a devastating complication after thoracoabdominal aortic repair.

Cardiovascular Disease and Stroke Risk Among Egyptian Resident Physicians: A Cross-Sectional Multicenter Study.

Background: Cardiovascular diseases (CVDs) are the leading cause of death worldwide and are considered silent killers that threaten different age groups. The stressful lifestyle of resident physicians might make them vulnerable to CVDs. Since 2021, Egypt has recently reported more frequent sudden deaths of junior physicians after long shifts.

Optimization and validation of high throughput methods for the determination of 132 organic contaminants in green and roasted coffee using GC-QqQ-MS/MS and LC-QqQ-MS/MS.

Safety and efficacy of P2X3 receptor antagonist for the treatment of refractory or unexplained chronic cough: A systematic review and meta-analysis of 11 randomized controlled trials.

Background And Objectives: Chronic refractory cough is a challenging condition that requires a thorough evaluation and management approach. P2X3 receptors that are ATP-dependent play an important part in nerve fiber sensitization and pathological pain pathways. We conducted this systematic review and meta-analysis to determine the long-term safety and efficacy of P2X3 receptor antagonist drugs in chronic cough.

The co-occurrent microplastics and nano-CuO showed antagonistic inhibitory effects on bacterial denitrification: Interaction of pollutants and regulations on functional genes.

The wide occurrence of microplastics (MPs) and nanoparticles resulted in their inevitable coexistence in environment. However, the joint effects of these two types of particulate emerging contaminants on denitrification have seldomly been investigated. Herein, non-biodegradable polyvinyl chloride, polypropylene, polyethylene and biodegradable polyhydroxyalkanoate (PHA) MPs were chosen to perform the co-occurrent effects with nano copper oxide (nano-CuO).

In vivo study of dose-dependent antioxidant efficacy of functionalized core-shell yttrium oxide nanoparticles.

Herein, we assess the dose-dependent antioxidant efficacy of ultrafine spherical functionalized core-shell yttrium oxide nanoparticles (YNPs) with a mean size of 7-8 nm and modified with poly EGMP (ethylene glycol methacrylate phosphate) and N-Fluorescein Acrylamide. The antioxidant properties of these nanoparticles were investigated in three groups of Sprague-Dawley rats (10 per group) exposed to environmental stress daily for 1 week and one control group. Groups 2 and 3 were intravenously injected twice a week with YNPs at 0.

An Electrostatic MEMS Roll-Pitch Rotation Rate Sensor with In-Plane Drive Mode.

In this paper, we presented a novel electrostatic Roll/Pitch MEMS gyroscope with in-plane drive mode and out-of-plane sense mode. The proposed structure is developed based on a tuning fork gyroscope with decoupled sense mass on each tine that control the sense out-of-plane frequency. A multi-height deep reactive ion etching (DRIE) fabrication process was utilized to achieve and enhance decoupling between the drive and sense modes.

Prevalence of the need for adaptive seating systems among children with cerebral palsy in Egypt.

Background: An adaptive seating system is a basic rehabilitation need for children and youth with cerebral palsy (CP) as it supports the structure and function of the musculoskeletal system and can positively affect their activities and participation. Despite the importance of adaptive seating systems, there is limited access to such systems in low-income countries.

Objectives: To determine the percentage of children and youth between 4 and 18 years of age with CP in Egypt whose activity level and sitting ability suggest the need for an adaptive seating system.

Sandwich injection and analyte protectants as a way to decrease the drift due to matrix effect between bracketing calibration in GC-MS/MS: A case study.

In pesticide residues analysis, the drift is the difference between the concentration of two bracketing calibrations in the same batch. According to the SANTE/12682/2019 guideline a criterion of ±30% must be met or positive samples should be reanalyzed. This study aimed to investigate, for the first time, the efficiency of using analyte protectants (Aps) and the sandwich injection approach (SIA) to eliminate the drift between bracketing matrix matched-calibrations taking strawberry as an example.

Resilient guaranteed cost control of a power system.

With the development of power system interconnection, the low-frequency oscillation is becoming more and more prominent which may cause system separation and loss of energy to consumers. This paper presents an innovative robust control for power systems in which the operating conditions are changing continuously due to load changes. However, practical implementation of robust control can be fragile due to controller inaccuracies (tolerance of resistors used with operational amplifiers).

Immunohistochemical staining of surfactant proteins A and B in skin of psoriatic patients before and after narrow-band UVB phototherapy.
