Increasing age and higher initial weight were defined as significant factors in predicting weight loss also. Researchers from Einstein Health care Network in Philadelphia followed 1,096 gastric bypass individuals with at least one-year follow-up. Patients were normally 45-years-outdated, and had an average body mass index of 47.6. Unwanted weight loss was 63.2 % in African-Americans and 71.9 % in whites, and 63 % in males, in comparison to 71 % in females. Resolution or improvement of obesity-related conditions, including Type 2 diabetes, sleep and hypertension apnea, were related across all combined organizations.Although powerful, this approach cannot mimic the response of vascular injuries and cannot monitor the cellular migration procedures under microscopy. Cells at the wound advantage polarize and migrate into the wound space. As to the studies of VSMCs, this process has been utilized to monitor cell migration, cell-substrate adhesion forces and the healing process. However, regular wound healing assays are carried out in micro-plates and cannot reproduce local vascular accidents and reconstruct regional microenvironments of VSMCs.Microfluidics is the technology and technology of manipulating and detecting fluids in the micro level.
