The movable bench cultivation system is a method of increasing area productivity and minimizing the energy needed in a greenhouse. In the system, all plants pass through the same watering point every day. This point should thus be the ideal place to measure precise plant growth information. In this study, we construct an experimental system for a 3D measurement of a community of strawberries cultivated on a 1-meter-long bench. The measurement was made every two to seven days from October 23, 2013 to January 13, 2014. As a result, we obtained 31 images of 10 plant beds. The estimation error of maximum plant height ranged from −30 mm to 32 mm, and that of width ranged from −42 mm to 40 mm. To visualize the growth information effectively, a 2D histogram of the distribution of the 3D points of the plant community was also calculated.

Objective: We explore the effects of body weight-supported (BWS) treadmill training, including the change of cortical activation, on a patient with post-stroke hemidystonia. Patient: The patient was a 71-year-old man with left thalamus hemorrhage. His motor symptoms indicated slight impairment. There was no overactive muscle contraction in the supine, sitting, or standing positions. During his gait, the right initial contact was the forefoot, and his right knee showed an extension thrust pattern. These symptoms suggested that he had post-stroke hemidystonia. Methods: The patient performed BWS treadmill training 14 times over 3 weeks. The effects of the BWS training were assessed by a step-length analysis, electromyography and functional magnetic resonance imaging (fMRI). Results: The patient's nonparetic step length was extended significantly in the Inter-BWS (p<0.001) and Post-BWS (p=0.025) periods compared to the Pre-BWS session. The excessive muscle activity of the right gastrocnemius medialis in the swing phase was decreased at the Inter-BWS, Post-BWS, and follow-up compared to the Pre-BWS session. The peak timing difference of the bilateral tibialis anterior muscle became significant (p<0.05) on the first day of the intervention. The fMRI revealed that the cortical areas activated by the motor task converged through the intervention (p<0.05, family-wise error corrected). Conclusion: These results suggest that there was improvement of the patient's symptoms of post-stroke hemidystonia due to changes in the brain activity during voluntary movement after BWS intervention. Body weight-supported treadmill training may thus be an effective treatment for patients with poststroke hemidystonia.

Objectives: We aimed to determine when a coexisting pseudocyst was likely to complicate the nonsurgical treatment of pancreatolithiasis.Methods: We treated 165 patients with pancreatolithiasis nonsurgically between 1992 and 2020, including 21 with pseudocysts. Twelve patients had a single pseudocyst less than 60 mm in diameter. Pseudocysts in the other nine patients had diameters of at least 60 mm or were multiple. The locations of pseudocysts along the length of the pancreas varied from the area with stone involvement to the pancreatic tail. We compared the outcomes in these groups.Results: We found no significant differences in pain relief, stone clearance, stone recurrence, or the likelihood of adverse events between pseudocyst groups or between patients with vs without pseudocysts. However, 4 of 9 patients with large or multiple pseudocysts required transition to surgical treatment (44%) compared with 13 of 144 patients with pancreatolithiasis and no pseudocyst (9.0%) (P=0.006).Conclusions: Patients with smaller pseudocysts typically underwent nonsurgical stone clearance successfully with few adverse events, similar to findings in patients with pancreatolithiasis and no pseudocysts. Pancreatolithiasis complicated by large or multiple pseudocysts did not cause more adverse events but was more likely to require transition to surgery compared with pancreatolithiasis without pseudocysts. In patients with large or multiple pseudocysts, early transition to surgery should be considered when nonsurgical treatment is ineffective.

A 69-year-old woman suspected to have IgG4-related sclerosing cholangitis causing bile duct stenosis was transferred from another hospital after diarrhea, eosinophilia, and eosinophilic infiltration were detected and prednisolone was prescribed. Additional biliary imaging suggested primary sclerosing cholangitis, but the IgG4 level and inferior bile duct stenosis were alleviated by steroid therapy, suggesting IgG4-related sclerosing cholangitis. Therefore, prednisolone was continued. Bile duct biopsy findings suggesting adenocarcinoma led to a diagnosis of pancreatoduodenectomy. The latter specimen only displayed evidence of primary sclerosing cholangitis, and prednisolone was discontinued. Intractable cholangitis necessitated left hepatectomy, after which serum alkaline phosphatase levels increased and eosinophilic colitis recurred. The reintroduction of prednisolone effectively managed the diarrhea but only temporarily reversed the alkaline phosphatase elevation. When histologic sections from resection specimens were compared, the hepatectomy specimen exhibited greater eosinophil infiltration than the earlier pancreatoduodenectomy specimen, suggesting eosinophilic cholangiopathy superimposed on primary sclerosing cholangitis.

Menopausal symptoms, bone loss, changes in lipid profiles and reduction of insulin sensitivity due to an abrupt decrease in circulating estrogen level are well known in women during the menopausal transition. On the other hand, the effect of androgen on women’s health has not been fully elucidated. Circulating levels of testosterone and dehydroepiandrosterone sulfate (DHEA-S) gradually decrease with age in postmenopausal women, although transient increases have been observed during the menopausal transition. High testosterone level has been suggested to be associated with increased risk of cardiovascular disease, increased triglyceride, insulin resistance and increase in the risk of developing breast cancer in postmenopausal women. Circulating DHEA-S level does not affect the risk of cardiovascular disease, mortality or lipid profiles in women. Female androgen insufficiency, which is characterized by the presence of reduced androgen level in circulation, leads to an impairment in sexual drive, reduced libido, depressed mood, and signs and symptoms of limited androgen exposure such as decreased muscle mass, reduced bone density and decreased sense of well-being. An appropriate level of androgen may play important roles in metabolic, psychological and sexual functions in women. In addition, the roles of testosterone and DHEA-S in women’s health may be different. J. Med. Invest. 59: 12-27, February, 2012

This review assesses the feasibility of using glycemic index (GI) as a predictor of appetite, hunger and satiety by surveying published human intervention studies. We also discuss the relationship between GI and two appetite/satiety control hormones, leptin and ghrelin. Ingestion of high-GI food increased hunger and lowered satiety in short-term human intervention studies. This effect may be attributed to the rapid decline in blood glucose level following a hyperinsulinemic response caused by a sharp and transient increase in blood glucose level that occurs after the ingestion of high-GI food, which is defined as the glucostatic theory. However, appetite, hunger and satiety after the ingestion of foods with varying GI were inconsistent among long-term human intervention studies. From the few relevant long-term studies available, we selected two recent well-designed examples for analysis, but they failed to elicit clear differences in glycemic and insulinemic responses between high- and low-GI meals (consisting of a combination of different foods or key carbohydrate-rich foods incorporated into habitual diets). One of the reasons that these studies could not predict glycemic response to mixed meals is presumably that the GI of each particular food was not reflected in that of the mixed meals as a whole. Thus, it is difficult to conclude that the GI values of foods or mixed meals are a valid long-term predictor for appetite, hunger and satiety. Both insulin and insulin-mediated glucose uptake and metabolism in adipose tissue affect blood leptin concentration and its diurnal pattern. Circulating ghrelin level is suppressed by carbohydrate-rich meals, presumably via glycemia and insulinemia. Accordingly, low-GI foods may not necessarily increase satiety or suppress appetite and/or hunger because of the lack of insulin-mediated leptin stimulation and ghrelin suppression. However, insulin-mediated leptin stimulation and ghrelin suppression per se is not consistent among studies; thus we were not able to identify a clear relationship among GI, satietogenic leptin, and appetitic ghrelin.
