Background/aim: Tacrolimus is an essential immunosuppressant for successful allogeneic haematopoietic stem cell transplantation (Allo-HSCT). This study aimed to examine the change in the blood concentration of tacrolimus during switching from intravenous to oral administration in allo-HSCT for paediatric cancer to predict the optimal dosage.
Patients And Methods: We retrospectively examined the medical records of 63 patients who received allo-HSCT and were administered tacrolimus. To compare bioavailability among different dose ranges, the blood concentration was divided by the dose (C/D).
Results: Thirty-nine patients (age range=children 1-15 years, adults 17-67 years) were switched to oral administration of tacrolimus. The C/D after switching was significantly lower in children than in adults (p=0.039). There was a strong positive correlation between age and C/D in children, whereas no correlation was observed in adults.
Conclusion: In paediatric cancer patients, switching tacrolimus administration route may result in reduced blood concentrations. This tendency is more prominent in younger children.

The effect of non-functionalized polystyrene nanoparticles (PS-NPs) with diameters of 29, 44, and 72 nm on plasmid DNA integrity and the expression of genes involved in the architecture of chromatin was investigated in human peripheral blood mononuclear cells (PBMCs). The cells were incubated with PS-NPs at concentrations ranging from 0.001 to 100 µg/mL for 24 hours.

Introduction: 5-Hydroxymethyl furfural (5-HMF) is a furan compound with a molecular formula of CHO. Studies have found that 5-HMF has many pharmacological effects, such as improving hemorheology, anti-inflammatory, antioxidant activity and anti-myocardial ischemia. Identifying the preventive effect of 5-HMF against ischemic stroke and its possible mechanism was the aim of this investigation.

Background: Emerging evidence suggests vitamin D plays a dual role in immune regulation, yet its interplay with genetic susceptibility in early-life allergy development remains poorly understood. This prospective cohort study investigated whether cord blood 25-hydroxyvitamin D [25(OH)D] levels interact with immunoregulatory gene variants to influence childhood food allergy risk.
Methods: A total of 1,049 mother-infant pairs from the Shanghai Allergy Cohort were stratified by cord blood 25(OH)D concentrations (<15, 15-25, >25 ng/mL).

The frequency and severity of heat waves are expected to worsen with climate change. Exposure to extreme heat, or prolonged unusually high temperatures, are associated with increased morbidity and mortality. The fetus, infant, and young child are more sensitive to higher temperatures than older children and most adults given that they are rapidly developing.

Objective: Our objective was to estimate the seroprevalences of 6 serovars in beef calves at or near fall weaning and assess how concentrations of serovar antibody titers in weaning-age calves varied with herd vaccination programs.
Animals: Serum was collected from 1922 beef calves from 106 herds in the Canadian Cow-Calf Surveillance Network (C3SN).
Procedure: A microscopic agglutination test was used to measure antibody titers for serovars Bratislava, Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae, and Pomona.
