Beta-galactosyl-pyrrolidinyl diazeniumdiolates (beta-Gal-NONOate) is a new site-specific nitric oxide (NO)-releasing compound, which releases NO once activated by beta-galactosidase. In the present experiment, we used beta-Gal-NONOate as a bactericidal reagent to investigate its effectiveness of NO releasing. Through the evaluation of intracellular NO level and the comparison of survival of E. coli transformed with lacZ gene but treated with beta-Gal-NONOate and NONOate, respectively, it's evident that beta-Gal-NONOate had a higher bactericidal activity than conventional NONOate. While either beta-Gal-NONOate- or NONOate-treated E. coli without transferred lacZ gene showed low bactericidal activity. The results revealed that beta-Gal-NONOate was a potentially efficient NO donor, which took on a novel and promising approach to deliver NO into cells.

Background: Acute lung injury (ALI) significantly impacts the survival rates in intensive care units (ICU). Releasing a lot of pro-inflammatory mediators during the progression of the disease is a core feature of ALI, which may lead to uncontrolled inflammation and further damages the tissues and organs of patients. This study explores the potential therapeutic mechanisms of Dexmedetomidine (Dex) in ALI.

Background: Chronic kidney disease (CKD) is a progressive loss of kidney function that can lead to end-stage renal disease (ESRD), requiring renal replacement therapy. Patients on chronic hemodialysis are at a higher risk of developing cardiovascular disease. This study aimed to investigate the effect of 12-week probiotic supplementation on insulin resistance, oxidative stress, and lipid profiles in diabetic patients with ESRD undergoing hemodialysis.

Background: There is a lack of suitable predictive markers for assessing the efficacy of amlodipine in treating children with primary hypertension. This study aimed to explore whether plasma calcitonin gene-related peptide (CGRP) and nitric oxide (NO) could predict the effectiveness of amlodipine in pediatric primary hypertension.
Methods: This study enrolled 74 children and adolescents with primary hypertension who were prescribed amlodipine monotherapy, and after 4 weeks of treatment, they were divided into responders and non-responders according to blood pressure.

Background: Osteocytes are crucial for detecting mechanical stimuli and translating them into biochemical responses within the bone. The primary cilium, a cellular 'antenna,' plays a vital role in this process. However, there is a lack of direct correlation between cilium length changes and osteocyte mechanosensitivity changes.
