In-vitro and in-vivo assessment of the bactericidal potential of peracetic acid and hydrogen peroxide disinfectants against A. hydrophila infection in Nile tilapia and their effect on water quality indices and fish stress biomarkers.

This study aimed to assess the in vitro and in vivo disinfectant potential of peracetic acid (PAA) (1 mg/L) and hydrogen peroxide (HO) (20 mg/L) on the physicochemical and microbiological water quality parameters of fish aquaria, the microbial density of Nile tilapia muscular tissue, fish hepatic cortisol levels, and antioxidant biomarkers. In vitro, PAA and HO reduced A. hydrophila colony viability by 5 log units after 30 and 5 min of contact time, respectively.

Evaluation of the mechanical properties and degradation behavior of chitosan-PVA-graphene oxide nanocomposite scaffolds in vitro.

Objectives: Chitosan (CTS) has been a popular option for scaffold fabrication because of its biocompatibility, biodegradability, antimicrobial and nonimmunogenic effects. However, it is of limited function, due to its low mechanical strength and its solubility in acidified media. These limitations could be overcome by its blending with PVA and incorporation with bioactive materials to improve its mechanical properties and tissue regeneration capability.

Evaluation of tumour motion and internal/external correlation in lung SABR.

Objective: This study aims to analyse lung tumour motion and to investigate the correlation between the internal tumour motion acquired from four-dimensional computed tomography (4DCT) and the motion of an external surrogate.

Methods: A data set of 363 4DCT images was analysed. Tumours were classified based on their anatomical lobes.

Optimum Operating Conditions for the Removal of Phosphate from Water Using of Wood-Branch Nanoparticles from .

A batch bio-sorption experiment was conducted on Dehnh. wood-branch in the form of woody sawdust nanoparticles (nSD-KF) to evaluate their potential efficiency as phosphate bio-sorption capacity. The operating parameters of phosphate bio-sorption including contact time, initial concentration, pH, temperature, dosage, size, competing ion, and the possible mechanisms responsible for phosphate removal from water were investigated.

Disruption of latent inhibition by subchronic phencyclidine pretreatment in rats.

Repeated subchronic treatment with the NMDA-receptor antagonist, phencyclidine, causes behavioural changes in rats, which resemble cognitive and negative symptoms of schizophrenia. However, its effects on behaviours modelling positive symptoms are less clear. This study investigated whether subchronic phencyclidine pretreatment affected latent inhibition: impaired conditioning following repeated preexposure of the to-be-conditioned stimulus.
