Purpose: Our primary aim was to elucidate the joint association between relative grip strength (RGS) and regular exercise participation with non-alcoholic fatty liver disease (NAFLD) incidence, utilizing longitudinal data. Methods: A total of 1,702 participants in this study comprised general adults aged 51 to 88 years, who had engaged in the survey both in 2013 to 2018 and during the subsequent follow-up in 2019 to 2020. NAFLD were determined by using the hepatic steatosis index. RGS was determined using the JAMA-5030J1 equipment (SAEHAN). To validate the relationship between the interaction of RGS and regular exercise participation and its impact on risk of developing NAFLD, a proportional hazards Cox regression model was used. Subsequently, we computed the hazard ratio (HR) and 95% confidence interval (95% CI) for NAFLD. Results: In the non-regular exercise group, middle RGS and high RGS reduced the HR for NAFLD by 29% (HR,0.71; 95% CI, 0.51–0.99) and 78% (HR, 0.22; 95% CI, 0.13–0.35), respectively, compared to low RGS. Significantassociations were observed only between high RGS and HR for NAFLD in the regular exercise group (HR, 0.40;95% CI, 0.22–0.72). Furthermore, in all subjects, both the high RGSon-regular exercise and high RGS/regular exercise groups showed a respective 60% (HR, 0.40; 95% CI, 0.29–0.56) and 54% (HR, 0.44; 95% CI, 0.31–0.63)lower HR for NAFLD compared to the low RGSon-regular exercise group. Conclusion This study investigates that high level of RGS were independently associated with reducing risk of developing NAFLD. RGS is an important factor that can predict the risk of developing NAFLD, and regular exercise participation is essential for increasing RGS.

OBJECTIVES: Neurological soft signs have been regarded as endophenotypes associated with the genetic basis of schizophrenia. This study was to investigate the intra-familial correlations of the neurological soft signs according to their genetic loading. METHODS: Schizophrenic patients(N=14) were included, who had one parent with a family history of schizophrenia and the other without it. Genetic loading was determined by the patient's family history of schizophrenia using the Family Interview for Genetic Studies(FIGS). These parents were subdivided into two groups. The first group was designated as'presumed carriers'(N=9) of genetic loading, who had one or more schizophreic first- or second-degree relatives. The second group was designated as'presumed non-carriers'(N=11) of genetic loading, who had no schizophrenic first- or second-degree relatives. Normal controls(N=12) consisted of people without schizophrenic relatives. NSS were evaluated using the Neurological Evaluation Scale-Korean Version (NES-K), and the intra-familial correlations of NSS were tested using the Intra-Class Coefficients(ICC) method. RESULTS: The scores of Motor Coordination subdimension of NES-K were significantly correlated between the patients and their presumed carriers(ICC=.804, p=.016), but not significantly correlated between the patients and their presumed noncarriers. In other subdimensions of NES-K, no significant correlation were found between the patients and their parents regardless of the genetic loading. But, there were no statistically significant differences in the scores of Motor Coordination subdimension of NES-K between the patients and controls. CONCLUSION: This study did not prove that the neurological soft signs might be an endophenotype of schizophrenia that cosegregate with the genetic loading. The future study using more subjects than this would be needed.

The facial nerve is mainly composed of motor fibers and is distributed to the muscles of facial expressions. In ophthalmology clinics, orbicularis oculi muscle innervated by the facial nerve is involved in spontaneous and voluntary blinking, winking, and more forceful eyelid closure. To understand pathophysiogy of facial nerve palsy due to brain stem lesion involving nucleus, 50% Horseradish Peroxidase (HRP) was injected into nerve stump innervating orbicularis oculi muscle of cat and serial sections of midbrain were studied with light and dark field of light microscope to examine morphology and distribution of the facial nuclei. The HRP-labelled motor neurons were located exclusively within the intermediate division of the ipsilateral facial nuclei and no labelled neurons were found in the contralateral facial nuclei, in the nuclei of the trigeminal nerve, or any other brain stem nuclei. The mean diameter of HRP-labelled motor neurons was 45 micrometer. Most of them were multipolar in shape containing many dendrites. These result suggest that the intermediate division of ipsilateral facial nuclei play an important role in innervating orbicularis oculi muscle.
