Development of analysis method for -xylenediamine as aldehyde scavenger using HPLC-PDA.

The objective of this study was to develop an analytical method for -xylenediamine (-XDA), an aldehyde scavenger, in various food simulants and food matrices. The analysis was performed using HPLC-UV (270 nm) with a Capcell pak MGII C18 column (4.6 × 250 mm, 5 μm).

A Potential Indicator Gene, tetM, to Assess Contamination by Antibiotic Resistance Genes in Greenhouses in South Korea.

Antibiotic resistance genes (ARGs) have been emerging as a concerning threat to both environment and public health. The continuous input of manure, irrigation water, and fertilizers increases the abundance of ARGs in agricultural environments. However, current risk assessments have focused on clinical settings, which are not applicable to environmental settings.

Effectiveness and safety of human placenta hydrolysate injection into subacromial space in patients with shoulder impingement syndrome: a single-blind, randomized trial.

Background: Human placental hydrolysate (hPH) contains anti-inflammatory substances. This study aimed to analyze whether injecting hPH into the subacromial space could reduce pain in patients with shoulder impingement syndrome.

Methods: This single-blind, randomized controlled study enrolled 50 patients with shoulder impingement syndrome who were randomly assigned to either the hPH or placebo groups.

Corticomuscular coherence existed at the single motor unit level.

The monosynaptic cortico-motoneuronal connections suggest the possibility of individual motor units (MUs) receiving independent commands from motor cortex. However, previous studies that used corticomuscular coherence (CMC) between electroencephalogram (EEG) signals and electromyogram (EMG) signals have not directly explored the corticospinal functionality at the single motoneuron level. The objective of this study is to find out whether synchronous activities exist between the motor cortex and individual MUs.

Optimizing Triage in Chemical Disasters: Validation of Modified IGSA Criteria for Hydrofluoric Acid Exposure.

Objective: This study aimed to develop and validate the modified irritant gas syndrome agent (IGSA) criteria, utilizing readily available triage information and epidemiologic data to efficiently segregate patients based on the severity of hydrofluoric acid (HFA) exposure.

Methods: A retrospective analysis of 160 patients exposed to HFA was performed to develop the criteria and assess the criteria's efficacy, focusing on age, respiratory rate, and compliance with IGSA standards. The criteria's validity was assessed by comparing clinical outcomes between patients meeting the modified IGSA (mIGSA) criteria and those who did not as external and internal.
