Methylmercury Determination in Fish by Direct Mercury Analyzer.

Background: There are two methods for quantifying methylmercury (MeHg) in fish using GC-electron capture detection (ECD): AOAC INTERNATIONAL Official Method 988.11 and the Korean Food Code (KFC) method. Both of these methods consume a large amount of chemicals and require long pretreatment times because of several complicated MeHg extraction steps.

[Characteristics and Risk Factors for Falls in Tertiary Hospital Inpatients].

Purpose: The aim of this study was to explore characteristics of and risk factors for accidental inpatient falls.

Methods: Participants were classified as fallers or non-fallers based on the fall history of inpatients in a tertiary hospital in Seoul between June 2014 and May 2015. Data on falls were obtained from the fall report forms and data on risk factors were obtained from the electronic nursing records.

Caenorhabditis elegans mitofilin homologs control the morphology of mitochondrial cristae and influence reproduction and physiology.

Human mitofilin is a mitochondrial protein that controls cristae formation. Here, we investigated the role of the Caenorhabditis elegans mitofilin homologs, IMMT-1 and -2, in reproduction, physiology, and mitochondrial cristae formation. Mutation of either immt-1 or immt-2 produced defects in germline development and egg-laying.

Three-dimensional structure of the cytoskeleton in Trichomonas vaginalis revealed new features.

The flagellated protozoan Trichomonas vaginalis has been widely studied owing to its medical significance and unique structure. The complicated three-dimensional (3D) structure of the cellular components of T. vaginalis was reconstructed from serial sections to enable observation of the spatial features of the whole cell.
