The purpose of this paper was to investigate the comparison of balance and muscle strength between dominant and non-dominant legs in adults. Thirty adults in their 20s participated in this study. The dominant and non-dominant legs were selected based on the dominant hands of the target. The subject's muscle strength of legs was measured with Nicholas MMT, and the balance was measured with BIO-Rescue. We compared the dominant and non-dominant legs based on the results. The result, indicated no statistical difference on balance and muscle strength between dominant and non-dominant legs(p>.05). The results of this study will be helpful in setting the effective treatment direction and treatment level, and in controlling posture, balance and motor function.

소나무재선충병의 나무주사는 살선충제를 중심으로 실시되어 왔으며, 매개충인 솔수염하늘소와 북방수염하늘소의 방제는 주로 항공방제나 지상방제를 통하여 이루어졌다. 본 연구에서는 나무주사를 통하여 매개충 (솔수염하늘소)을 방제하기 위한 연구로 Abamectin+Acetamiprid ME, Thiamethoxam DC 약제의 나무주사시 솔수염하늘소의 약효발현농도, 처리 후 기간별 효과(2017년~2018년)를 검토하였다. 실내 발현농도 시험에서는 Acetamiprid, Thiamethoxam LC50 value는 각각 0.102ppm, 0.083ppm 으로 나타 났으며, 야산(포장)에서 Abamectin+Acetamiprid ME, Thiamethoxam DC 처리구의 100.0% 치사 소요일 수는 처리 90일 후 11.0일, 9.4일, 처리 360일 후 11.6일, 10.0일로 나타나서 두 약제 모두 3월 처리시 다음해에 발생하는 매개충 (솔수염하늘소) 방제까지 가능함을 확인 할 수 있었다.

The aim of this study was to investigate the effects of foot position adjuster on body alignment and weight loads in chronic stroke patients. The subjects were 15 chronic stroke patients who were admitted to KHospital in Daegu, South Korea. The study compared the body alignment and weight load changes on flat ground with the foot position adjuster using Foot scan and Dartfish video analysis software. In the results of this study, posterior superior iliac spine (PSIS) alignment decreased significantly after use of the foot position adjuster and center pressure was significantly increased after use of the foot position adjuster. This study suggests that foot position adjuster influences body alignment and weight distribution.

The development of nanostructured functional materials derived from biomass and/or waste is of growing importance for creating sustainable energy-storage systems. In this study, nanoporous carbonaceous materials containing numerous heteroatoms were fabricated from waste coffee grounds using a top-down process via simple heating with KOH. The nanoporous carbon nanosheets exhibited notable material properties such as high specific surface area (1960.1 m2 g–1), numerous redox-active heteroatoms (16.1 at% oxygen, 2.7 at% nitrogen, and 1.6 at% sulfur), and high aspect ratios (>100). These unique properties led to good electrochemical performance as supercapacitor electrodes. A specific capacitance of ~438.5 F g–1 was achieved at a scan rate of 2 mV s–1, and a capacitance of 176 F g–1 was maintained at a fast scan rate of 100 mV s–1. Furthermore, cyclic stability was achieved for over 2000 cycles.

Apolipophorin-III (apoLp-III) is a hemolymph protein whose function is to facilitate lipid transport in an aqueous medium in insects. Recently, apolipophorin-III in Galleria mellonella and Hyphantria cunea was shown to play an unexpected role in insect immune activation. We show here a novel possible function/role of the apoLp-III in insects. To investigate the genes which have a relationship with apoLp-III in fall webworm larvae, we reduced endogenous Hc apoLp-III mRNA levels in larvae via RNA interference (RNAi). The RNAi-mediated Hc apoLp-III reduction resulted in the reduction of antioxidants, like MnSOD, catalase, and glutathione S transferase as well as immune proteins. In particular, expression of MnSOD commonly decreased in fat body, midgut, and hemocytes following the knockdown of Hc apoLp-III, which induced an elevated level of superoxide anion in Hyphantria cunea larvae. The observed effect of Hc apoLp-III RNAi suggests that Hc apoLp-III is related to the action/expression of antioxidants, especially MnSOD.

Previous studies indicated that Matsumuraeses phaseoli and M. falcana (Lepidoptera: Tortricidae) are separate species since a few differences were observed in genitalia morphology and female sex pheromone composition. A clear difference was detected in the DNA sequences of cytochrome oxidase I of the two species separately collected in different plants and regions. A hybridization test also showed that a post-zygotic reproductive isolation occurred between the species. In field monitoring, however, both species have been caught simultaneously and together in the separate sex pheromone traps installed for the two species around neighboring soybean and red bean fields. Molecular marker-assisted identification with several adults sampled from the trapped insects showed that only ca. 40% of M. phaseoli adults identified as the species by genitalia morphology was the M. phaseoli, while ca. 97% of M. falcana adults identified as the species was the M. falcana. The result indicated that the observation of genitalia did not make a decisive criterion for classification of the insects. Conclusively, it suggested that the sex pheromones of the two species should be studied more precisely although there is a possibility that the two species are hybridized in fields as in laboratory, and speciation is under process.

Pregnancy is a unique event in which a fetus develops in the uterus despite being genetically and immunologically different from the mother, and the underlying mechanisms remain poorly understood. To analyze the differential gene expression profiles in nonpregnant and 7 days post coitus (dpc) pregnant uterus of mice, we performed a global proteomic study by 2‐D gel electrophoresis (2‐DE) and MALDI‐TOF‐MS. The uterine proteins were separated using 2‐DE. Approximately 1,000 spots were detected on staining with Coomassie brilliant blue. An image analysis using Melanie III (Swiss Institute for Bioinformatics) was performed to detect variations in protein spots between pregnant and nonpregnant uterus. Twenty‐one spots were identified as differentially expressed proteins, of which 10 were up‐regulated proteins such as alpha‐fetoprotein, chloride intracellular channel 1, transgelin, heat‐shock protein beta‐1, and carbonic anhydrase II, while 11 were down‐regulated proteins such as X‐box binding protein, glutathione S‐transferase omega 1, olfactory receptor Olfr204, and metalloproteinase‐disintegrin domain containing protein TECADAM. Most of the identified proteins appeared to be related with catabolism, cell growth, metabolism, regulation, cell protection, protein repair, or protection. Our results uncovered key proteins of mouse uterus involved in pregnancy.

The Maillard Reaction Products (MRPs) such as Glucose-tyrosine (Glu-Tyr) and Xylose-arginine (Xyl-Arg) have antioxidant, antimutagenic, and antibacterial effects. However, to date, still little is known about the other biological effects of the MRPs. In this study, we investigated whether the fructose-tyrosine MRP, 2,4-bis(p-hydroxyphenyl)-2-butenal (Fru-Tyr), could modulate cell cycle progression and NF-κB activity, and thereby induce apoptotic cell death of colon cancer cells. Treatment with different concentrations (10-40 μg/ ml) of Fru-Tyr for 24 h inhibited colon cancer cell (SW620 and HCT116) growth followed by induction of G₂/M phase cell cycle arrest and apoptosis in a dose-dependent manner. We also found that Fru-Tyr suppressed tumor necrosis factor-alpha (TNF-α)-induced NF-κB transcriptional activity. Moreover, Fru-Tyr induced the expression of apoptotic gene, cleaved caspse-3. These results suggest that Fru-Tyr inhibited colon cancer cell growth through induction of G₂/M phase cell cycle arrest and apoptotic cell death by modulating of NF-κB.

Innate immunity responses are triggered by the immune challenge and therefore involve signaling processes. The cellular response is initiated by hemocytes and mainly involves phagocytosis and encapsulation of intruders by these cells. To address whether Hc-STAT is activated upon bacterial challenge, we examined the subcellular location of STAT protein in hemocyte by immunostaining. A new insect member of the STAT family of transcription factors (Hc-STAT) has been cloned from the lepidopteran, Hyphantria cunea. The domain involved in DNA interaction and the SH2 domain are well conserved. The gene is transcribed at a low level during all stages of development, and the protein is present in hemocytes, fat body, midgut, epidermis, and Malphigian tuble (Mt). Especially, hemocytes and Mt showed transcriptional activation of Hc-STAT upon Gram (-) bacteria and fungal challenge. Gram (-) bacteria and fungal challenge specifically results in nuclear translocation of Hc-STAT protein and induction of DNA-binding activity that recognizes a STAT target site in H. cunea hemocyte. In vitro treatment with pervanadate translocates Hc-STAT to the nucleus in hemocyte cells. Here we report the first evidence for the involvement hemocyte JAK/STAT pathway upon microbial infection in lepidopteran insect.
