Parsing the link between reinforcement sensitivity theory and eating behavior: A systematic review.

The Reinforcement Sensitivity Theory (RST) is a widely studied psychobiological model of personality. RST factors seem to influence eating behavior, but how these personality traits are associated with distinct features of eating behavior is still unclear. In the present systematic review, we analyzed the relationship between RST personality factors and eating behavior using a parsing approach in which BMI-related results, self-reported results, and behavioral results were distinguished.

Integrated optical sensor platform for multiparameter bio-chemical analysis.

There is growing demand for robust, reliable, low cost, and easy to use sensor systems that feature multiparameter analysis in many application areas ranging from safety and security to point of care and medical diagnostics. Here, we highlight the theory and show first experimental results on a novel approach targeting the realization of massively multiplexed sensor arrays. The presented sensor platform is based on arrays of frequency-modulated integrated optical microring resonators (MRR) fed by a single bus waveguide combined with lock-in detection to filter out in a reliable and simple manner their individual response to external stimuli.

Functional vascular diseases: Raynaud's syndrome, acrocyanosis and erythromelalgia.

Raynauds syndrome, acrocyanosis and erythromelalgia are functional vascular diseases that differ with respect to prevalence, clinical picture, therapy, prognosis, and impairment of quality of life. Raynauds syndrome occurs in 5 to 20 % of the population in Europe, is observed four times more often in women than in men and appears first at the age of 40 (3 to 80), on the average. Raynauds attacks are characterized by a paroxysmal white-blue-red or just white and blue discoloration of the fingers and toes; the attacks are induced by cold or stress, usually, cease after no more than some minutes (average 23 min.

A microring resonator sensor for sensitive detection of 1,3,5-trinitrotoluene (TNT).

A microring resonator sensor device for sensitive detection of the explosive 1,3,5-trinitrotoluene (TNT) is presented. It is based on the combination of a silicon microring resonator and tailored receptor molecules.

Asymptomatic venous thrombosis in cancer patients--a problem often overlooked. Results of a retrospective and prospective study.

Background: Venous thrombosis with and without pulmonary embolism is a frequent complication of malignancies and second among the causes of death in tumour patients. Its incidence is reported to be 10 to 15%. Since for methodological reasons, this rate can be assumed to be too low and to disregard asymptomatic venous thrombosis, a combined retrospective and prospective study was performed to examine the actual frequency of venous thrombosis in tumour patients.
