Phenotype-genotype correlation in patients with typical and atypical branchio-oto-renal syndrome.

Some patients have an atypical form of branchio-oto-renal (BOR) syndrome, which does not satisfy the diagnostic criteria, despite carrying a pathogenic variant (P variant) or a likely pathogenic variant (LP variant) of a causative gene. P/LP variants phenotypic indices have yet to be determined in patients with typical and atypical BOR syndrome. We hypothesized that determining phenotypic and genetic differences between patients with typical and atypical BOR syndrome could inform such indices.

Correction to: Risk factors for vancomycin nephrotoxicity and time course of renal function during vancomycin treatment.

After online publication, we found a typographical error in Table 2. We consider correcting "VCM trough concentration > 20 g/mL" to "VCM trough concentration > 20 μg/mL".

Risk factors for vancomycin nephrotoxicity and time course of renal function during vancomycin treatment.

Purpose: Vancomycin (VCM) is used for the treatment of methicillin-resistant Staphylococcus aureus. Although the risk factors for VCM nephrotoxicity have been evaluated, the time course of renal function during VCM treatment is unknown. We assessed risk factors for VCM nephrotoxicity and how renal function varied over time.

Two-Point Method for Measuring the Temporal Modulation Transfer Function.

Objective: The temporal modulation transfer function (TMTF) has been proposed to estimate the temporal resolution abilities of listeners with normal hearing and listeners with hearing loss. The TMTF data of patients would be useful for clinical diagnosis and for adjusting the hearing instruments at clinical and fitting sites. However, practical application is precluded by the long measurement time of the conventional method, which requires several measurement points.

Frequency and specific characteristics of the incomplete partition type III anomaly in children.

Objectives/hypothesis: To determine the frequency of the incomplete partition type III anomaly and the genetic and clinical features associated with POU3F4 mutations in children with hearing loss.

Study Design: Retrospective case series from 2000 to 2014 at the National Hospital Organization Tokyo Medical Center and collaborating hospitals.

Methods: A total of 1,004 patients (from 938 families) who had hearing loss by 10 years of age and had undergone computed tomography scanning of their temporal bones were enrolled in this genetic, clinical, and radiological study.

Enhancement of anti-cholinesterase activity of aqueous samples by hypochlorite oxidation for monitoring traces of organophosphorus pesticides in water.

A reproducible method for monitoring traces of cholinesterase (ChE) inhibitors in aqueous samples is described: the method is based on chemical oxidation and a ChE inhibition assay. Chlorine was tested as an oxidizing reagent for conversion of various thiophosphorus pesticides (P=S compounds) into their P=O analogs, which have higher ChE-inhibiting activity. After treating buffered pesticide solutions (pH 6.

Mutagenic potentials of Amberlite XAD-2-resin extracts obtained from river and drinking waters in the Northwest district of Chiba, Japan.

Amberlite XAD-2 resin extracts of river and drinking water sampled from the Northwest district of Chiba Prefecture in each month during the period from January to December 2008 were investigated to characterize and determine their mutagenic potentials and polycyclic aromatic hydrocarbon (PAH) levels. The extracts from the river water were shown to be mutagenic in Salmonella typhimurium TA98 (a flameshift mutagen) without S9 mix, with higher mutagenic responses in summer and early fall seasons. While the drinking water extracts exhibited weak mutagenicity in both the TA98 and TA100 strains (a base-pair substitution mutagen) without S9 mix, with high mutagenic responses in fall and early winter seasons.
