BACKGROUND The impact of the coronavirus on hospitalizations for gastrointestinal(GI)disease,particularly at a population level is *** To investigate trends in hospitalizations,inpatient endoscopy resource utilization,and outcomes during the first year of the coronavirus pandemic and subsequent *** Using the California State Inpatient Database for 2018-2020,we explored year-toyear and 2020 month-to-month trends in hospitalizations,length of stay,and inpatient mortality(all-cause&viral pneumonia-specific)for common inpatient GI diagnoses including acute pancreatitis,diverticulitis,cholelithiasis,noninfectious gastroenteritis,upper and lower GI bleeding(LGIB),Clostridium difficile,viral gastroenteritis,inflammatory bowel disease,and acute *** Disease-specific hospitalizations decreased for all included conditions except nonvariceal upper GI bleeding(NVUGIB),LGIB,and ulcerative colitis(UC)(ptrend<0.0001).Allcause inpatient mortality was higher in 2020 vs 2019,for acute pancreatitis(P=0.029),diverticulitis(P=0.04),NVUGIB(P=0.003),and Crohn’s disease(P=0.004).In 2020,hospitalization rates were lowest in April,November,and *** was no significant corresponding increase in inpatient mortality except in UC(ptrend=0.048).Viral pneumonia and viral pneumonia complicated by respiratory failure increased(P<0.001)among GI *** utilization within 24 h of admission was unchanged for GI emergencies except NVUGIB(P<0.001).CONCLUSION Our findings suggest that hospitalization rates for common GI conditions significantly declined in California during the COVID pandemic,particularly in April,November and December *** mortality was significantly higher among acute pancreatitis,diverticulitis,NVUGIB,and Crohn’s disease *** endoscopy rates were mostly comparable between 2020 and 2019.

With the increasing use of humanoid robots in several sectors of industrial automation and manufacturing, navigation and path planning of humanoids has emerged as one of the most promising area of research. In this paper, a navigational controller has been developed for a humanoid by using fuzzy logic as an intelligent algorithm for avoiding the obstacles present in the environment and reach the desired target position safely. Here, the controller has been designed by careful consideration of the navigational parameters by the help of fuzzy rules. The sensory information regarding obstacle distances and bearing angle towards the target are considered as inputs to the controller and necessary velocities for avoiding the obstacles are obtained as outputs. The working of the controller has been tested on a NAO humanoid robot in V-REP simulation platform. To validate the simulation results, an experimental platform has been designed under laboratory conditions, and experimental analysis has been ***, the results obtained from both the environments are compared against each other with a good agreement between them.

在检验现场对轴测图进行电子化高效测绘是实现压力管道检验过程数字化、智能化的重要手段。本文提出了适用于压力管道现场快速检验的轴测图编制方法。通过惯性导航快速获取管道走向数据,通过三角形对边测距方法测量管道长度,通过多次坐标变换将管道三维线框模型转化为二维轴测图,据此开发出压力管道轴测图测绘仪。检验系统由智能平板电脑、测绘仪、超声波测厚仪等模块组成,可实现自动或手动绘制管道轴测图并在检验系统App端交互式录入现场检验数据。通过检验实例介绍了该系统应用过程。结果表明,所研发的检验系统可极大地提高压力管道检验效率和检验过程数字化、智能化水平。

Astragalin and rutin restore gut microbiota dysbiosis， alleviate obesity and insulin resistance in high-fat diet-fed C57BL/6J mice

引用

Food Science and Human Wellness 2023年

作者： muni Swamy Ganjayi Karunakaran Reddy Sankaran Balaji Meriga Ruchika Bhatia Shikha Sharma Kanthi Kiran Kondepudi Department of Biochemistry， Sri Venkateswara University Food and Nutrition Biotechnology Division， National Agri-Food Biotechnology Institute

In the present study we investigated the impact of the Combination of Astragalin and Rutin (CAR) on restoring gut-microbial dysbiosis and obesity and obesity related disorders. Randomized male C57BL/6J mice were experimentally divided into five groups and fed either a normal diet or a high-fat diet (HFD) for 16 weeks. Compared to vehicle treated group (HFD group)， CAR could substantially improve selected gut microbiota abundance (Akkermansia， Lactobacillus， Bifidobacteria， muciniphila， Roseburia)， reversed the Firmicutes/Bacteroidetes proportions， and inhibited the growth of Escherichia coli， Salmonella， and Klebsiella in obese mice. In addition， CAR-treated mice showed significantly (P < 0.05) increased total short-chain fatty acid production， reduced body weight gain， organs’ weights， serum lipid profile (except HDL) and insulin resistance. The mRNA expressions of CCAAT/enhancer binding protein-α (C/EBP-α)， sterol regulatory element-binding protein-1c (SREBP-1c)， peroxisome proliferator-activated receptor-γ (PPAR‐γ)， acetyl-CoA carboxylase (ACC)， adipocyte protein 2 (aP2)， and fatty acid synthase (FAS) were downregulated (P < 0.05) and the protein expression of PPAR-γ was downregulated while AMPK was phosphorylated in CAR-treated HFD-fed mice compared to the HFD control group. Interestingly， CAR-treated HFD-fed mice showed significantly improved tissue architecture in the liver and fatty tissues. In conclusion， the findings suggest that CAR/Moringa oleifera may be beneficial in the treatment of insulin resistance and obesity disorders.

A Study on Visual Diversity of Japanese Residential Streetscapes

引用

Journal of Civil Engineering and Architecture 2015年第5期9卷 626-634页

作者： Garu muni Wathsala Lakpriya Gunawardena Kubota Yoichi Kiyotaka Fukahori Graduate School of Science and Engineering Saitama University Saitama-shi 338-8570 Japan

This study was conducted to find out the available visual diversity in Japanese residential streetscapes. The visual diversity occurs when the visual elements on streetscapes are different to each other. In this study, a field survey as a subjective method and the entropy as an objective method were used as measures of visual diversity. Data were collected from 80 residential streetscapes from four sites in the Saitama Prefecture, Japan. The sequential perspective views of streetscapes were analyzed for eight visual elements： shape of houses, shape of roofs, shape of windows, positions of the main openings of houses, availability of the ornaments on houses, height, color and the appearance of the boundary walls of premises to calculate the entropy. A field survey with multicultural subjects was used to find out the correlation between entropy and the human perception on the visual diversity. According to the results, the residential streetscapes displayed high diversity variations largely due to the shape of the roofs, shape of the windows and the appearance of the boundary walls of the premises. Moreover, the results concluded that the residential streetscapes at the study area are neither visually diverse nor visually uniform in considering the visual diversity aspect.
