Although rare, infection with Streptococcus anginosus has a known predilection for abscess formation. We report here a case of a 20 year-old, otherwise healthy female patient noted to have developed abdominal and pelvic abscesses secondary to Streptococcus anginosus infection. Although the inciting focus of the pathogen remains unclear in our patient, this case report emphasizes the importance of rapid identification of the organism and highlights the approach to therapeutic options in the management of such cases.

Since Type 1 diabetes(T1DM)occurs whenβ-cells mass is reduced to less than 20%of the normal level due to autoimmune destruction of cells resulting in the inability to secrete insulin,preservation or replenishment of the functionalβ-cells mass has become a major therapeutic focus for this diabetic type ***,this 4-week work plan was designed to determine which mesenchymal stem cells(MSCs)type is more appropriate to alleviate pancreatic hazards resulting from diabetes induction;via tracking a comparative study between MSCs derived from adipose tissue(AD-MSCs)and from bone marrow(BM-MSCs)in management of T1DM considering their immunomodulatory,anti-apoptotic and antioxidative *** were divided randomly into 4 groups;control,STZdiabetic(D),D+AD-MSCs,and D+BM-MSCs *** stem cells types in this study were ***,both oxidative stress and antioxidant markers were evaluated using colorimetric analysis,while inflammatory,immune and apoptotic markers were assessed through flow cytometric *** showed that diabetic rats treated with either AD-MSCs or BM-MSCs exhibited marked pancreatic antioxidant and anti-inflammatory activities that were able to initiate pancreatic immunomodulation and reducingβ-cells apoptotic death,thus,help to restore their normal insulin secretion and hypoglycemic ***,AD-MSCs injection was shown to be superior as a pancreatic regenerative tool in overcoming diabetes;owing to their marked antioxidant,anti-inflammatory,immunomodulatory,and anti-apoptotic characteristics over BM-MSCs treatment.

Background: Mobility limitations and cognitive impairments which are common with ageing often coexist, causing a reduction in the levels of physical and mental activity and are prognostic of future adverse health events and falls. Consequently, multi-task training paradigms that simultaneously address both mobility and cognition benefit healthy ageing are important to consider in rehabilitation as well as primary prevention. Objectives: An exploratory RCT is being conducted to: a) describe the feasibility and acceptability of the study design and process, procedures, resources and management in two game-based dual-task training programs delivered in the community;b) to explore the lived experiences of the study participants who completed their respective exercise programs. A secondary objective is to obtain preliminary data on the therapeutic effectiveness of the two dual-task training programs. Methods: Thirty healthy older community dwelling participants aged 70 - 85 with previous history of falls will be recruited and randomized to either dual- task treadmill walking (experimental group) or dual-task recumbent bicycle (control group). Data analysis: The qualitative data will be analyzed by two investigators using a content analysis approach. For the quantitative data, outcome measures will be collected pre and post intervention and included measures to assess core balance, spatial-temporal gait variables, visual tracking and cognitive function, as well as, balance and gait analysis under dual-task conditions. Discussion: This research will demonstrate the feasibility of the dual-task training programs in the community, and demonstrate the system’s ability to improve targeted and integrated (dual-task) aspects of balance, mobility, gaze, and cognitive performance. A blended analysis of balance, mobility gaze and cognition will also contribute to a better understanding of the functional consequences of decline in physical and mental skills with age.

毋庸置疑,新手中文教师教学水平不是一朝一夕就能显著提高的。一般来说,教师需要经历理论学习、摸索与实践、反思和再实践,直至有所创新,这是一个长期过程。这一过程的长短和顺利与否与教师本人的专业基础、工作态度、工作环境以及个人性格等诸多因素密不可分。帮助新手中文教师在参加工作之初就尽快进入角色,努力缩短他们从新手教师到学生基本满意的合格教师再到优秀教师这一过程的时间,我认为至少可以从如下这些方面着手。

AIM To investigate the clinical utility of serum annexin A2(ANXA2) as a diagnostic marker for early hepatocellular carcinoma(HCC).METHODS This study was performed in HCC Clinic of Ain Shams University Hospitals, Cairo, Egypt and included: Group 1: Fifty patients with early stage HCC(Barcelona Clinic Liver Cancer stage A); Group 2: Twenty five patients with chronic liver disease; and Control Group: Fifteen healthy, age-and sex-matched subjects who were seronegative for viral hepatitis markers. The followinglaboratory investigations were done: Viral hepatitis markers [hepatitis B surface antigen and hepatitis C virus(HCV) antibodies], HCV RNA in HCV antibody-positive patients, serum alpha fetoprotein(AFP), and serum ANXA2 *** In this study, 88% of HCC patients(n = 44) were HCVpositive, while HBV infection represented only 8% of all HCC patients(n = 4); and two patients were negative for both viral markers. A highly significant difference was found between patients with HCC and chronic liver disease as well as controls with regard to serum ANXA2 levels(130, IQR 15-240; 15, IQR 15-17; and 17, IQR 15-30 ng/m L, respectively). The area under the curve of ANXA2 was 0.865; the cut-off value was established to be 18 ng/mL with a diagnostic sensitivity of 74% and a specificity of 88%, while the sensitivity and specificity of AFP at the cut-off value of 200 ng/dL were 20% and 100%, *** Serum ANXA2 may serve as a biomarker for the early detection of HCC.

-Air-conditioning （AC） systems are the major energy consumption units in residential and commercial buildings. In the context of smart grid, optimizing AC operations leads to substantial saving in energy consumption, reducing the consumer＇s bill and contributing to the environment by minimizing carbon emissions from generating stations. This paper presents a distributed AC energy management system for buildings by using networked master-slaves controller architecture. The proposed system was designed, simulated, and experimentally tested by using real AC units in a students＇ residence hall. Based on the students＇ class schedules, several operational scenarios were implemented and tested. The proposed system implementation leads to a 40% to 60% saving of the consumed energy by the tested units. The same energy management scheme can be applied and implemented in other commercial and residential buildings.

This work represents the extraction of oil with high free fatty acid content from spent bleaching earth using sub-critical water technology as a greener production pathway. The extraction efficiencies under different conditions were investigated. The studied parameters include temperatures in the range of 180 to 270°C, the feed to solventfeed-to-solvent (in this case water) ratio (1:1, 1:2, 1:3, 1:4 and 1:5) and extraction times in the range of 5-60 minutes. The results showed that the optimum temperature, feed to solventfeed-to-solvent ratio, and extraction time were 270°C, 1:3, and 20 minutes, respectively. In another experiment, the extracted free fatty acids were converted into mono-, di-, and triglycerides through esterification with glycerol to increase the value added of the extracted products. The kinetics of the extraction process was found to be corresponding to an irreversible consecutive unimolecular-type first order reaction, consisting of the extraction step followed by the decomposition reaction step. Both reaction rates of extraction and decomposition were estimated using the reaction rate equations utilizing the nonlinear regression method. The apparent activation energy was calculated to be 46.1 kJ·mol-1. This result indicates a diffusion controlled reaction. For more exploration and deep understanding of the extraction mechanism, other thermodynamic parameters were also calculated and analyzed including,ΔH#, ΔS#, and ΔG# of the extraction step.
