To establish which constituents of blood influence the NMR relaxation time T1 of water protons in malignant blood diseases, 55 blood samples were studied (20 from healthy donors and 35 from patients with leukaemia, myelofibrosis and multiple myeloma). Relaxation time measurements were performed at 19.8 MHz resonance frequency and at a temperature of 33 +/- 1 degree C. There is a significant elevation of T1 over the normal level in whole blood, packed cells, and plasma of patients with blood disease. The relaxation rate R1 (= 1/T1) depends very strongly on the ratio of dry solids to water, which is in accordance with the three-state fast-exchange relaxation model.

Impact of choline choride and sugar natural deep eutectic solvents on structure and functionality of treebean (Parkia timoriana) seed protein.

This study explores the impact of natural deep eutectic solvents (NADES) on the structure and functionality of treebean (Parkia timoriana) seed protein, a novel approach to enhancing protein stability and functionality for sustainable bioprocessing. The research aims to evaluate the dynamic interactions between protein and choline chloride-sugar-based NADES, focusing on their effects on thermal properties, emulsification behaviour, and rheological characteristics. NADES were formulated using different sugars, and protein-NADES dispersions were analysed for their physicochemical and functional properties.

Peribulbar anesthesia is mainly used for cataract surgery. Many studies had used atracurium and rocuronium as an additive to the local anesthetic (LA) drugs in eye surgery. The aim of this study is to evaluate the efficacy of adding atracurium versus rocuronium to a local anesthetic mixture, in providing an early onset of orbital akinesia and corneal anesthesia during cataract surgery.

Microsurgical learning is a difficult and stressful process, requiring self-control to achieve relaxation. The purpose of this study is to evaluate peripheral and central nervous system relaxation during microsurgical training. This cohort study included ten medical students with no previous experience in microsurgery.

Background: Although accessing administrative data in healthcare databases may be a more time-efficient and cost-effective method of conducting surveillance, there is evidence suggesting that administrative data alone are not sufficient for population-based surveillance of congenital anomalies.
Objective: To propose recommendations to maximise the potential use of healthcare databases for surveillance of congenital anomalies based on our data linkage experiences and results from the EUROlinkCAT study.
Methods: EUROlinkCAT is a population-based cohort study of 99,416 children with anomalies born between 1995 and 2014.
