The extent, rate, and time of load-induced length changes during myocardial contraction appear to be the primary variables affecting crossbridge activity and energetics. Load and length regulation of the properties of the heart represents a remarkably simple and direct biological response to the ...
Laser microprocessing of metallic stent for medical therapy In the stent therapy for the medical applications, especially in coronary heart disease, the metallic stent of high quality demands the ability for precisi... YP Kathuria - 《Journal of Materials Processing Technology》 被引量: 76发表: ...
The animal's vital physiological parameters (temperature, respiration, heart rate, blood pressure) were mon- itored throughout the surgery. After shaving and cleaning with surgical disinfectant the skin overlying the skull, the low back, and dorsal aspects of the right shank, skin incisions were...
Baseline medical history and examination at the time of study enrollment were used to determine demographics (age, sex, ethnicity),body mass index(BMI),New York Heart Association functional class, duration ofcardiomyopathy, and presence of comorbidities such as hypertension, diabetes,hypercholesterolemia,...
(SENSE) factor = 2.5; field of view = 195 × 215 mm; echo train length = 1; number of average (NEX) = 1; and acquisition time = 4 minutes. The scan parameters used for the follow-up were as follow: ratio of TR to TE = 23–25/3.45 ms; flip angle = 20°;...
The proximal fracture of the femur and hip is the most common reason for hospitalization in orthopedic departments. Hip fractures put patients at risk of cardiovascular, pulmonary, thrombotic, infectious, and bleeding complications that can lead to death [1]. The only strategy to prevent immediate ...
diseases and death. This biological deterioration is considered a major risk factor for cancer, cardiovascular diseases, diabetes and Alzheimer’s disease among others. At the cellular level, there are two key hallmarks of the aging process: shortening of telomere length and cellular senescence [1]...
referred for exercise stress echocardiography and 16 controls. The PASP was derived from the tricuspid Doppler tracing. A cut-off value of PASP ≥ 50 mmHg at peak stress was considered as indicative of abnormal increase in PASP. Diastolic times and the diastolic/systolic time ratio were recorded...
Preferably, the vacuum pump is only operated in a short period of time each time a tissue sample is to be harvested, i.e. immediately prior to severing of the tissue sample. Control of the operation of the vacuum pump may e.g. be coupled to control of the cutting mechanism and/or to...
Age was calculated as the difference between the date of birth and date of surgery. Body mass index (BMI) was calculated using height and weight before surgery. Comorbidities were extracted from previous medical history and included hypertension, diabetes mellitus (type 1 and 2), heart disease, ...
