Carotid to femoral pulse wave velocity (PWV) is associated with an increase in cardiovascular morbidity and all-cause mortality. Noninvasive approach has made this method applicable for the examination of larger populations. This study aimed to obtain reference values of PWV measured with the Vicorder device. PWV was obtained using the oscillometric Vicorder in 318 healthy, normotensive patients (165 women, 28.7±17.6 years, range 6-83 years). A plethysmographic sensor was placed over the right carotid region to pick up the carotid pulse wave and a blood pressure cuff was placed around the upper thigh to trace the femoral pulse wave. Path length was defined as the distance from the suprasternal notch to the top of the thigh cuff. Mean PWV was 6.1±1.4 m/s and significantly increased with age (r=.842; P<.0001). PWV was associated with mean arterial pressure (r=.546; P<.0001) and body mass index (r=.396; P<.0001). In a multiple linear regression model, age, mean arterial pressure, and body height emerged as independent markers for PWV. This study established reference values for carotid to femoral PWV derived by oscillometric measures that can now be used for risk stratification.

Infrared neural stimulation has consistently shown that temperature is a critical neuronal state variable. However, a comprehensive understanding of the biophysical background is essential. In this study, using high-density laminar electrode recordings, we investigated the impact of pulsed and continuous-wave infrared illumination on cortical neurons in anesthetized rats ([Formula: see text]).

Background: Patients with type 1 diabetes (DM1), even in the setting of adequate glycaemic control, have an excess risk for developing cardiovascular disease. Residual insulin secretion (RIS), measured by detectable C-peptide levels in patients with DM1, might protect against diabetes-related complications. This study aimed to examine the relationship between residual insulin secretion and prognostic markers of cardiovascular complications in patients with DM1.

Background: Although emerging evidence suggests that indole derivatives, microbial metabolites of tryptophan, may improve cardiometabolic health, the effective metabolites remain unclear. Also, the gut microbiota that involved in producing indole derivatives are less studied. We identified microbial taxa that can predict serum concentrations of the key indole metabolite indole-3-propionic acid (IPA) at population level and investigated the associations of indole derivatives and IPA-predicting microbial genera with cardiometabolic risk markers.

Background -Smoking is associated with arrhythmia and sudden cardiac death, but the biological mechanisms remain unclear. In electrocardiogram (ECG) recordings abnormal durations of ventricular repolarization (QT interval), atrial depolarization (P wave), and atrioventricular depolarization (PR interval and segment), predict cardiac arrhythmia and mortality. Previous analyses of the National Health and Nutrition Examination Survey (NHANES) database for associations between smoking and ECG abnormalities were incomplete.

A novel variant of paired-associative stimulation (PAS) consisting of high-frequency peripheral nerve stimulation (PNS) and high-intensity transcranial magnetic stimulation (TMS) above the motor cortex, called high-PAS, can lead to improved motor function in patients with incomplete spinal cord injury. In PAS, the interstimulus interval (ISI) between the PNS and TMS pulses plays a significant role in the location of the intended effect of the induced plastic changes. While conventional PAS protocols (single TMS pulse often applied with intensity close to resting motor threshold, and single PNS pulse) usually require precisely defined ISIs, high-PAS can induce plasticity at a wide range of ISIs and also in spite of small ISI errors, which is helpful in clinical settings where precise ISI determination can be challenging.
