Article Synopsis
- Protein post-translational modifications (PTMs) with acyl groups are important in the bacteria Streptomyces, but their further modification and effects on physiology haven't been well explored.
- In Streptomyces roseosporus, a luciferase enzyme called LimB regulates levels of crotonylation, affecting cell development and antibiotic production by oxidizing crotonyl groups on an enzyme called Acs.
- This oxidative modification triggers the breakdown of Acs through a specific protease pathway, leading to lower levels of crotonyl-CoA, indicating that post-PTM modifications (PPM) are significant for protein regulation and could be common in various organisms.
Anammox is one of the most innovative nitrogen removal technologies, while its functional bacteria-anaerobic ammonia-oxidizing bacteria (AAOB) is sensitive to the impurities in the wastewater. In this study, the long-term effects of sulfide at different concentrations (0, 5, 10, 20, 30, 50, 25 mg L) on low substrate Anammox process were studied. The results showed that when the sulfide was 25-30 mg L, AAOB was well coupled with sulfide-denitrifying bacteria and the total nitrogen removal efficiency (TNRE) reached a maximum of 91.

- * The study measured heavy metals (Pb, Cr, Cd, As) in APPMs using inductively coupled plasma-mass spectrometry (ICP-MS), achieving excellent calibration curves and low detection limits.
- * Results showed high recovery rates for metal detection with minimal variation, indicating that the method is reliable and precise for analyzing these elements in APPMs or similar materials.
Objective: Using two antithrombotic treatment (clopidogrel vs. clopidogrel combined warfarin) strategies after femoral-popliteal artery angioplasty prospectively, to evaluate which strategy is more effective for the restenosis prevention.
Methods: Totally 50 patients referred for endovascular treatment (including the percutaneous transluminal angioplasty (PTA) and stent implantation) of the superficial femoral artery and popliteal artery from January 2008 to May 2009 were randomly divided into clopidogrel group (group A, 25 cases, 30 limbs) and clopidogrel plus warfarin group (group B, 25 cases, 33 limbs) before operation.
Early diagnosis of acute mesenteric ischemia (AMI) remains very difficult, partly due to the fact that useful markers of early small bowel ischemia have not yet been identified. Thus, in this study, we aimed to evaluate the levels of serum intracellular enzymes in the tissues and organs in a controlled animal model of mesenteric intestinal ischemia. Forty-eight New Zealand rabbits were divided into 4 groups including the control, artery ligation, vein ligation, and both artery and vein ligation groups.
