Clinical Characteristics and In Vivo Confocal Microscopic Study in Candida Keratitis.

Purpose: To clarify the clinical and imaging characteristics of Candida keratitis using in vivo confocal microscopy (IVCM) for improved early diagnosis and management.

Methods: A retrospective study of 40 patients with Candida keratitis at Beijing Tongren Hospital from January 2015 to December 2023 was conducted. Data included demographics, risk factors, clinical assessments, lab tests, and IVCM images.

Enhancing Waterproof Food Packaging with Janus Structure: Lotus Leaf Biomimicry and Polyphenol Particle Technology for Vegetable Preservation.

With the increasing demand for improved food preservation, conventional waterproof food packaging has proven inadequate because of its limited functionality. Although incorporating features such as antibacterial and antioxidant properties into packaging enhances protection, it can compromise the hydrophobicity of the involved material, thereby increasing the risk of contamination from external sources. To address this challenge, a robust and reliable barrier capable of simultaneously integrating multiple protective functions is required.

Immobilization of Saccharomyces cerevisiae on polyhydroxyalkanoate/konjac glucan nanofiber membranes: Characterization, immobilization efficiency and cellular activity.

Yeast immobilization systems can recoup yeast losses in continuous batch fermentation and relieve substrate or product inhibition. We report the use of solution blow spinning process to efficiently prepare polyhydroxyalkanoate (PHB) /konjac glucomannan (KGM) nanofiber membranes as immobilization carriers for Saccharomyces cerevisiae. The prepared PHB/KGM nanofiber membranes had fiber diameters similar to the scale of yeast cells.

A rapid preparation strategy of konjac glucomannan-based fiber film incorporated with elderberry anthocyanins via microfluidic blow spinning for fresh-cut apple preservation.

It is still a challenge to use a fast and efficient method for preserving fresh-cut fruits from browning. To address this problem, we developed konjac glucomannan (KGM) incorporated with elderberry anthocyanins (EA) to form film-forming solution (KEA) combined with polyvinylpyrrolidone (PVP) solution to produce KEA/PVP fiber films by microfluidic blow spinning (MBS). The introduction of PVP and EA improved the spinnability and function properties of KGM-based fiber film, respectively.

Plasma Epstein-Barr Virus DNA load for diagnostic and prognostic assessment in intestinal Epstein-Barr Virus infection.

Background: The prospective application of plasma Epstein-Barr virus (EBV) DNA load as a noninvasive measure of intestinal EBV infection remains unexplored. This study aims to identify ideal threshold levels for plasma EBV DNA loads in the diagnosis and outcome prediction of intestinal EBV infection, particularly in cases of primary intestinal lymphoproliferative diseases and inflammatory bowel disease (IBD).

Methods: Receiver operating characteristic (ROC) curves were examined to determine suitable thresholds for plasma EBV DNA load in diagnosing intestinal EBV infection and predicting its prognosis.
