Background:None of the published studies involving cancer cachexia experimental models have included a measure of the severity of the syndrome like the scoring system previously developed for human subjects.The aim of the present investigation was to define and validate a cachexia score usable in both rat and mouse tumor models.Methods:In order to achieve this goal,we included in the study one rat model(Yoshida AH‐130ascites hepatoma)and two mouse models(Lewis lung carcinoma and Colon26 carcinoma).The Animal cachexia score(ACASCO)includes five components:(a)body and muscle weight loss,(b)inflammation and metabolic disturbances,(c)physical performance,(d)anorexia,and(e)quality of life measured using discomfort symptoms and behavioral tests.Results:Using the ACASCO values,three cut‐off values were estimated by applying hierarchical cluster analysis.Four groups were originally described,one exactly below the observed mean,a second exactly over the mean,and two other groups adjusted to every cue(inferior and superior).The three cut‐off values were estimated through maximization of the classification function.This was accomplished by using a similarity matrix based on the metric properties of the variables and assuming multinormal distribution.The results show that the four groups were:no cachexia,mild cachexia,moderate cachexia and advanced cachexia.Conclusions:The results obtained allow us to conclude that the score could be very useful as an endpoint in pre‐clinical studies involving therapeutic strategies for cancer cachexia.The potential usefulness of ACASCO relates to the primary endpoint in pre‐clinical cancer cachexia drug evaluations.

Introduction:The rapidly growing field of regenerative medicine incorporates fundamental principles of stem cell biology and biomedical engineering to repair tissues damaged by genetic disorder,degeneration,or traumatic injury.The global market for stem cell therapies is expanding at an accelerating rate and projected to triple to over 100 Billion USD by the end of the decade(No author listed,2019),as per Figure 1A.

Age-related changes in the brain connectivity of healthy older adults have been widely studied in recent years,with some differences in the obtained results.Most of these studies showed decreases in general functional connectivity,but they also found increases in some particular regions and areas.Frequently,these studies compared young individuals with older subjects,but few studies compared different age groups only in older populations.The purpose of this study is to analyze whole-brain functional connectivity in healthy older adult groups and its network characteristics through functional segregation.A total of 114 individuals,48 to 89 years old,were scanned using resting-state functional magnetic resonance imaging in a resting state paradigm and were divided into six different age groups(<60,60–64,65–69,70–74,75–79,≥80 years old).A partial correlation analysis,a pooled correlation analysis and a study of 3-cycle regions with prominent connectivity were conducted.Our results showed progressive diminution in the functional connectivity among different age groups and this was particularly pronounced between 75 and 79 years old.The oldest group(≥80 years old)showed a slight increase in functional connectivity compared to the other groups.This occurred possibly because of compensatory mechanism in brain functioning.This study provides information on the brain functional characteristics of every age group,with more specific information on the functional progressive decline,and supplies methodological tools to study functional connectivity characteristics.Approval for the study was obtained from the ethics committee of the Comision de Bioetica de la Universidad de Barcelona(approval No.PSI2012-38257)on June 5,2012,and from the ethics committee of the Barcelona’s Hospital Clinic(approval No.2009-5306 and 2011-6604)on October 22,2009 and April 7,2011 respectively.

3．2研究2：室外暴露传统h基于居住区评估的暴露，如室外空气污染、噪声、建筑环境，可以通过收集时间一空间活动以及（就空气污染而言）个人吸入空气量的信息，改善暴露评估和减小测量误差。例如，可替代吸入率（Kawahara等，2011）的体力活动方面的信息与个人空气污染测量结合来评估吸入剂量。基于暴露评估的新一代地理信息系统（GIS）（Beelen等，2013;Eeflens等，2012）、遥感（Dadvand等，2012）和智能手机技术（deNazelle等，2013）使评估室外暴露和整合个人活动范围及体力活动数据变得更容易。
