To address the most appropriate endogenous biomarker for drug–drug interaction risk assessment, eight healthy subjects received an organic anion transporting polypeptide 1B (OATP1B) inhibitor (rifampicin, 150, 300, and 600 mg), a probe drug cocktail (atorvastatin, pitavastatin, rosuvastatin, valsartan). In addition to coproporphyrin I, widely studied OATP1B biomarker, we identified at least 4 out of 28 compounds (direct bilirubin, glycochenodeoxycholate‐3‐glucuronide,...

3-Hydroxyisobutyryl-CoA hydrolase (HIBCH) deficiency is an autosomal recessive disorder characterized by episodes of ketoacidosis and a Leigh-like basal ganglia disease, without high concentrations pyruvate lactate in the cerebrospinal fluid. Only 4 cases HIBCH have been reported. However, clinical-biochemical correlation determining detailed residual enzyme activities has not yet elucidated. Here, we report case two Japanese siblings with carrying new homozygous missense mutation (c.287C >...

The branched-chain α-ketoacid dehydrogenase (BCKDH) complex regulates amino acid (BCAA) catabolism by controlling the second step of this catabolic pathway. In present study, we examined in vivo effects treatment with an mTORC1 inhibitor, rapamycin, on cardiac BCKDH activity mice.

Supergenes are sets of genes and genetic elements that inherited like a single gene control complex adaptive traits, but their functional roles units poorly understood. In Papilio polytes, female-limited Batesian mimicry is thought to be regulated by ∼130 kb inversion region (highly diversified region: HDR) containing 3 genes, UXT, U3X, doublesex (dsx) which switches non-mimetic mimetic types. To determine the unit, we here performed electroporation-mediated RNAi analyses (and further...

The obtained dialysis over 5–7 days, the solvent replaced with phosphate buffer completely remove impurities, which could be scavengers radicals produced as a result water radiolysis. samples films dilute aqueous solutions were used separately evaluate contributions X rays (150–160 kVp). irradiated analyzed...

From first-principle band structure calculations the Heusler alloys Fe2MnSi and Co2MnSi are predicted to be half-metals, if ferromagnetic state is assumed. In reality, however, exhibits a complex magnetic with antiferromagnetic components, while high Curie temperature probably half metal. order search better half-metals Fe2-xCox MnSi worth investigating. We have studied properties of Fe2-xCo:cMnSi experimentally. With increasing Co concentration from x = 0, phase rapidly disappears. The...

Novel feeding adaptations often facilitate adaptive radiation and diversification. But the evolutionary origins of such can be puzzling if they require concordant change in multiple component parts. Pelagic, heterorhabdid copepods (Calanoida) exhibit diverse behaviors that range from simple particle to a highly specialized form carnivory involving piercing mouthparts likely inject venom. We review history add new high-resolution, 3D anatomical analyses muscular system, glands gland openings...
