Article Abstract

Interest in xylanases from different sources has increased markedly in the past decade, in part because of the application of these enzymes in the pulp and paper industry. Purity and purification costs are becoming important issues in modern biotechnology as the industry matures and competitive products reach the marketplace. Thus, new paths for successful and efficient xylanase recovery have to be followed. This article reviews the isolation and purification methods used for the recovery of microbial xylanases. Origins and applications of xylanases are described, highlighting the special features of this class of enzymes, such as the carbohydrate-binding domains (CBDs) and their importance in the development of affinity methodologies to increase and facilitate xylanase purification. Implications of recombinant DNA technology for the isolation and purification of xylanases are evaluated. Several purification procedures are analyzed, taking into consideration the sequence of the methods used in each and the number of times each method is used. New directions to improve xylanase separation and purification from fermentation media are described.

Objective: Globally, over 50% of the population is affected by , yet research on its prevalence and impact in patients with obesity undergoing laparoscopic sleeve gastrectomy (LSG) is inconclusive. This study aimed to assess the prevalence of infection in individuals with obesity undergoing LSG, evaluate the percentage of postoperative staple-line leaks, and explore the potential link between infection and staple-line leaks.

Methods: This retrospective analysis assessed adult patients with class III obesity who underwent LSG between 2015 and 2020 at a tertiary care hospital in Riyadh, Saudi Arabia.

Cyanobacterial distributions are shaped by abiotic factors including temperature, light and nutrient availability as well as biotic factors such as grazing and viral infection. In this study, we investigated the abundances of T4-like and T7-like cyanophages and the extent of picocyanobacterial infection in the cold, high-nutrient-low-chlorophyll, sub-Antarctic waters of the southwest Pacific Ocean during austral spring. Synechococcus was the dominant picocyanobacterium, ranging from 4.

An FPGA-Based SiNW-FET Biosensing System for Real-Time Viral Detection: Hardware Amplification and 1D CNN for Adaptive Noise Reduction.

Department of Computer Science, Faculty of Sciences and Humanities Sciences, Majmaah University, Al Majmaah 11952, Saudi Arabia.

Impedance-based biosensing has emerged as a critical technology for high-sensitivity biomolecular detection, yet traditional approaches often rely on bulky, costly impedance analyzers, limiting their portability and usability in point-of-care applications. Addressing these limitations, this paper proposes an advanced biosensing system integrating a Silicon Nanowire Field-Effect Transistor (SiNW-FET) biosensor with a high-gain amplification circuit and a 1D Convolutional Neural Network (CNN) implemented on FPGA hardware. This attempt combines SiNW-FET biosensing technology with FPGA-implemented deep learning noise reduction, creating a compact system capable of real-time viral detection with minimal computational latency.
