Synthesis and Unique Behaviors of High-Purity HEA Nanoparticles Using Femtosecond Laser Ablation.

High-entropy alloys (HEAs) are a class of metal alloys consisting of four or more molar equal or near-equal elements. HEA nanomaterials have garnered significant interest due to their wide range of applications, such as electrocatalysis, welding, and brazing. Their unique multi-principle high-entropy effect allows for the tailoring of the alloy composition to facilitate specific electrochemical reactions.

Cholecystectomy via Kocher incision without peritoneal closure.

This investigation was carried out to evaluate the surgical wound outcome of patients who underwent cholecystectomy via Kocher incision, without peritoneal closure. Consecutive patients (n = 129) were randomized either to have the peritoneal closure (n = 66) or to have this step omitted (n = 63). Demographic data of the patients were similar in both groups.

Monitoring for clenbuterol abuse in N. Ireland 1989-1994.

Laboratory testing in N. Ireland for the illegal growth promoting agent, clenbuterol (CBL), is centralized at the Veterinary Sciences Division, Belfast. During the past 6 years a variety of testing schemes have evolved to determine the level of abuse of this drug in the local meat industry.

Determination of the concentrations of the steroids estradiol, progesterone and testosterone in bovine sera: comparison of commercial dissociation enhanced lanthanide fluorescence immunoassay kits with conventional radio and enzyme immunoassays.

The performance of three conventional enzyme and radioimmunoassays routinely used to detect residues of anabolic steroids in cattle sera were compared with dissociation enhanced lanthanide fluorescence immunoassay (DELFIA) kits designed for the hospital market. Slight modifications to the kit reagents were required for the analysis of bovine sera. Owing to the large sample volumes used in conventional assays, detection limits were generally better than those obtained with DELFIA kits, however, assay reproducibility was enhanced using the DELFIA technology.

Residues of the beta-agonist clenbuterol in tissues of medicated farm animals.

Reports of the illegal use of clenbuterol as a growth promotant prompted the development of a competitive enzyme immunoassay for this drug. This procedure was utilized to study the elimination of clenbuterol from tissues in sheep medicated with both therapeutic and growth-promoting doses of the drug. The results indicated that prior to removal of medication clenbuterol was widely distributed throughout the animal tissues.

Continuous ambulatory peritoneal dialysis in children.

Fifteen children with end-stage renal failure (ESRF) were treated with continuous ambulatory peritoneal dialysis (CAPD) in the Children's Hospital Temple Street Dublin between July 1984 and December 1988. These fifteen children had 150.5 treatment months, an average of 10.

Iron and nutritional status of toddlers.

The iron and nutritional status of 22 clinically well and normal toddlers, aged from one to four years inclusive was determined. Mean energy intake was normal. Protein, fibre and ascorbic acid intakes were high.

Relapse in primate malaria: its implications for the disease in man.

In a recently promulgated theory of the occurrence of relapses in malaria, the authors of this theory state that the mosquito which feeds on a case of malaria of a species which is subject to relapses produces two kinds of sporozoite. One of these gives rise to an attack of malaria while the other remains dormant in a cell of the host's liver without change for an indefinite time. It can later undergo development to produce a relapse.
