Seasonality, control, and risk factors for Gasterophilus intestinalis egg intensity in horses from Romania under field conditions.

This study aimed to assess the efficacy of pyrethroid-based insecticides against Gasterophilus spp. egg-laying activity and to establish the seasonality patterns in the specific climatic area of Transylvania, Romania. To fulfil the aims of the study, a total of 40 horses were treated every 4 weeks and inspected every 2 weeks between 11 May and 6 November (Pilo et al.

Normal horizontal VOR gain and catch-up saccades: still a diagnostic dilemma.

Purpose: To analyze the relationship between normal horizontal vestibular-ocular reflex (VOR) gain with catch-up saccades (CS) in patients reporting recurrent or chronic vestibular symptoms of unknown causes.

Methods: A prospective study involving 34 patients suffering from vestibular symptoms of unknown origin; all subjects presented bilateral normal horizontal VOR gain and CS on at least one side. Data collection regarded onset and duration of vestibular symptoms.

Client Oriented Scale of Improvement in First-Time and Experienced Hearing Aid Users: An Analysis of Five Predetermined Predictability Categories through Audiometric and Speech Testing.

The aim of our investigation was to explore the relationship between unaided pure-tone and speech audiometry and self-reported aided performance measured according to five predetermined COSI categories among first-time hearing aid users and experienced hearing aid users. Data from 286 patients were retrospectively evaluated. We divided the sample into first-time hearing aid users (G1) and experienced hearing aid users (G2).

Hydrogen Atom Transfer (HAT)-Mediated Remote Desaturation Enabled by Fe/Cr-H Cooperative Catalysis.

An iron/chromium system (Fe(OAc), CpCr(CO)H) catalyzes the preparation of β,γ- or -unsaturated amides from 1,4,2-dioxazol-5-ones. An acyl nitrenoid iron complex seems likely to be responsible for C-H activation. A cascade of three H• transfer steps appears to be involved: (i) the abstraction of H• from a remote C-H bond by the nitrenoid N, (ii) the transfer of H• from Cr to N, and (iii) the abstraction of H• from a radical substituent by the Cr•.
