OBJECTIVES: A non-alcoholic fatty liver disease (NAFLD) has high prevalence and now important issue of public health. In general, there exists strong interaction between NAFLD and diabetes, but the detailed mechanism is unclear. In this study, we determined the effects of hyperglycemia on progression in the early phase of NAFLD in mice. METHODS: Male ddY mice were fed a choline-deficient, l-amino acid-defined, high-fat diet (CDAHFD) consisting of 60% of kcal from fat and 0...

OBJECTIVES: Oxethazaine (OXZ) is one of the few local anaesthetics that provides analgesia at low pH, but presents poor solubility, cytotoxicity and no parenteral formulations. To address these issues, we aimed to prepare OXZ host-guest inclusion complex with hydroxypropyl-beta-cyclodextrin (HP-β-CD). METHODS: The inclusion complex was formed by co-solubilization, followed by a job plot analysis to determine stoichiometry of complexation and dialysis equilibrium analysis (based on UV/VIS absorption and fluorescence profiles of OXZ)...

OBJECTIVES: This minireview focuses on novel degradation pathways of proteins in solution via intermediary tryptophan (Trp) radical cations, which are generated via photo-induced electron transfer to suitable acceptors such as disulfide bonds. METHODS: Gas-phase mass spectrometry studies had indicated the potential for Trp radical cations to fragment via release of 3-methylene-3H-indol-1-ium from the side chain. HPLC-MS/MS analysis demonstrates that analogous fragmentation reactions occur during the exposure of peptides and proteins to light or accelerated stability testing...

OBJECTIVE: Polyethylene glycol (PEG)-induced protein precipitation is often used to extrapolate apparent protein solubility at specific formulation compositions. The procedure was used for several fields of application such as protein crystal growth but also protein formulation development. Nevertheless, most studies focused on applicability in protein crystal growth. In contrast, this study focuses on applicability of PEG-induced precipitation during high-concentration protein formulation development...

OBJECTIVE: To provide an overview of non-parenteral clonidine formulations and assess the feasibility of their use for paediatric sedation. METHODS: A literature search was conducted using electronic databases and a combination of search terms. Forty articles met the inclusion criteria. Publications were grouped into different dosage forms and assessed for their potential application for sedation of children in intensive care. KEY FINDINGS: Several routes of clonidine administration have been investigated for numerous indications in children, including perioperative sedation and analgesia...

OBJECTIVE: To examine factors that might affect the ability of patients to accurately halve tablets or measure a 5-ml liquid dose. METHODS: Eighty-eight participants split four different placebo tablets by hand and using a tablet splitter, while 85 participants measured 5 ml of water, 0.5% methylcellulose (MC) and 1% MC using a syringe and dosing cup. Accuracy of manipulation was determined by mass measurements. KEY FINDINGS: The general population was less able than pharmacy students to break tablets into equal parts, although age, gender and prior experience were insignificant factors...
