ABSTRACT Background Amyotrophic lateral sclerosis (ALS) is a neuromuscular disease that causes degeneration of both upper and lower motor neurons. TAR DNA‐binding protein 43 kDa (TDP‐43) mislocalized in the neurons patients with ALS. TDP‐43 regulates RNA metabolism, including alternative splicing. Although dysregulation splicing by supposed to have key role ALS pathology, nature aberrant tissues has not been well studied. Aim To screen for alterations find those linked pathology. Methods...

ABSTRACT Objective Waist circumference measurement is commonly used as a method for predicting the visceral fat area. However, waist difficult to measure, and there large margin of error between measurements. Visceral adipose tissue that accumulates in abdominal cavity, when it excess, computed tomography reveals prominent protrusion anterior–posterior diameter abdomen coronal section at umbilicus level. Individuals with obesity often show forward protrusions. This study aimed verify whether...

The interfacial tension between molten iron and slag was measured by the sessile drop method with transmission X-ray technique. Oxygen in remarkably decreased surface of melt at slag-metal boundary. It suggests that oxygen dissolved acts as a active solute interface. Consequently, depended, most part, on content melt, but composition had minor effect tension.In order to clear tension, experimental results were discussed terms Δσ(=σm-σms) indicated difference constant sufrace melt. values Δσ...

Despite numerous reports that have linked diabetes with cognitive impairment (CI), there are few studies attempted to clarify the morbidity of CI among elderly diabetic patients. The Mini-Mental State Examination (MMSE) was performed on 240 patients aged 65 years or older who had no diagnosis dementia. MMSE scores were 28-30 (normal range) in 151 (63%), 24-27 (suspected CI) 77 (32%), and ≤ 23 (definite 12 (5%). Eight underwent further detailed examination: final Alzheimer's disease (AD) (N =...

ABSTRACT We assessed the association of neutrophil function with glycated hemoglobin (HbA1c) levels in a Japanese general population. Participants were 809 males and females who over 20 years old living Iwaki region Aomori Prefecture located northern Japan. Lifestyle parameters (smoking, alcohol consumption, exercise habits), HbA1c such as reactive oxygen species (ROS) production capability phagocytic activity (PA) measured. ROS was measured before after stimulus to obtain basal stimulated...

Although type 2 diabetes mellitus (DM) is a risk factor for the development of dementia, underlying brain pathologies and mechanisms vary among patients. In this study, we classified patients with clinically diagnosed Alzheimer's disease (AD) associated DM into subgroups based on their amyloid tau accumulation patterns positron emission tomography (PET), analyzed differences in clinical features imaging findings between subgroups. Sixty-four probable or possible AD were using PiB (detects...

Objective For measuring serum 3,3′,5′-triiodothyronine (rT3) levels, radioimmunoassay (RIA) has traditionally been used owing to the lack of other reliable methods; however, it recently become difficult perform. Meanwhile, liquid chromatography-tandem mass spectrometry (LC-MS/MS) attracting attention as a novel alternative method in clinical chemistry. To best our knowledge, there are no studies date comparing results quantification human rT3 between LC-MS/MS and RIA. We therefore examined...
