Lactic acid/tartaric acid-maltitol antibacterial activity against spoilage bacteria and prevention of yellowing and wilting in spinach and oilseed rape.

The wilting and yellowing of leafy vegetables caused by spoilage bacteria resulted in serious resource wastage. This study investigated the efficacy of a combined lactic acid (LA) and tartaric acid (TA) treatment against four predominant spoilage bacteria (Erwinia persicina, Citrobacter freundii, Pseudomonas putida, and Pseudomonas punonensis) isolated from spinach and oilseed rape. Detailed analysis using Fourier-transform infrared spectroscopy, flow cytometry, scanning electron microscopy, and light microscopy revealed substantial cellular damage in the bacteria treated by LA and TA, including loss of intracellular material, and collapse of cellular morphology, as well as effective biofilm removal.

Endogenous hydrogen sulfide persulfidates endothelin type A receptor to inhibit pulmonary arterial smooth muscle cell proliferation.

Background: The binding of endothelin-1 (ET-1) to endothelin type A receptor (ETAR) performs a critical action in pulmonary arterial smooth muscle cell (PASMC) proliferation leading to pulmonary vascular structural remodeling. More evidence showed that cystathionine γ-lyase (CSE)-catalyzed endogenous hydrogen sulfide (HS) was involved in the pathogenesis of cardiovascular diseases. In this study, we aimed to explore the effect of endogenous HS/CSE pathway on the ET-1/ETAR binding and its underlying mechanisms in the cellular and animal models of PASMC proliferation.

Gelatinase-responsive core-shell nanofiber membranes for anti-adhesion applications.

Running-In Behavior and Failure Mechanism Between AgCuNi Alloy and Au-Electroplated Layer.

To avoid wear and tear of the slip ring due to electrical corrosion, the slip ring needs to undergo the running-in process under atmospheric conditions without current after assembly. To address the urgent demand for long-service capability space conductive slip rings in the aerospace field, the running-in behavior and failure mechanism between the AgCuNi alloy and Au-electroplated layer are investigated using a ball-on-disc tribometer in this paper. The results show that the transfer film composed of Au plays an important role in modifying the friction during the sliding process.

Pathways for Identifying Problems in Nursing Quality on-Site Supervision: A Descriptive Qualitative Study.

Background: When the nursing department of our hospital checked the ward round records of the head nurse, it was found that some problems could not be found during rounds, and most of the problems found were superficial; Some studies have also found that most nursing managers are only going through the motions during rounds or are unable to identify problems due to a mismatch between their professional competence and the supervised department, or fail to identify superficial or deep-seated problems, making the quality of nursing supervision unsatisfactory.

Purpose: To sort out the ideas and ways for nursing managers to identify problems in on-site supervision of nursing quality and to provide ideas and directions for being able to identify problems, identifying problems quickly, and identifying high-quality problems in the supervision.

Methods: A descriptive qualitative study was used to conduct face-to-face semi-structured interviews with 14 nursing managers from Bethune Hospital in Shanxi, China.
