Objective: To study some factors (temperature, time, anticoagulate, reagent, apparatus) which influence the detection of serum enzyme.
Methods: Serums obtained from same patient are determined in different conditions. Compare the statistical difference among each group.
Results: The anticoagulant-heparinize Li influence the determination of ADA and CH50. If serums were sent in room temperature for 24 hours, the results will be different. Using regents from different factories will receive different results.
Conclusion: Different conditions and reagents will influence results. To obtain correct data, we must institute and perform standard regulation.

Renal osteodystrophy is commonly seen in patients with chronic kidney disease (CKD) due to disrupted mineral homeostasis. Given the impaired renal function in these patients, common anti-resorptive agents, including bisphosphonates, must be used with caution or even contraindicated. Therefore, an alternative therapy without renal burden to combat renal osteodystrophy is urgently needed.

Cone-beam computed tomography (CBCT) assisted bronchoscopy shows prospective advantages in diagnosing peripheral pulmonary lesions (PPLs), but its diagnostic value and potential influencing factors remain unclear. What is the clinical value and optimal strategy of CBCT-assisted bronchoscopy in diagnosing PPLs? The references were searched from PubMed, EmBase, and Web of Science. Studies reporting diagnostic yield and potential influencing factors of CBCT-assisted bronchoscopy were included.

Hydrogen atom transfer (HAT) reactions and their kinetic barriers Δ are important in organic and inorganic chemistry. This study examines factors that influence Δ, reporting the kinetics and thermodynamics of HAT from various ruthenium bis(acetylacetonate) pyridine-imidazole complexes to nitroxyl radicals. Across these 36 reactions, the Δ and Δ can be independently varied, with different sets of Ru complexes primarily tuning either their ps or their °s.

Introduction: Home care workers (HCWs) are paid caregivers who provide support to patients with chronic conditions and functional limitations. Additionally, they provide emotional support to patients and familial support. Although several qualitative studies have been conducted on HCWs, they focused more on studying prevalently the lived experiences about the workplace violence, the end of life, stressor and resilience, during the COVID-19 pandemic or focused more in dementia and heart failure, but not on feelings and working conditions.

Introduction: Relaxin is a hormone primarily produced by the corpus luteum during pregnancy, and it plays a critical role in various physiological processes related to pregnancy and childbirth.
Evidence Acquisition: Studies have suggested a possible link between relaxin levels and preterm birth. Relaxin's effects on the cervix and pelvic ligaments suggest it could influence the mode of delivery.
