paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. they are rarely located in retroperitoneal space. these tumors are often discovered incidentally during imaging studies performed for other reasons.periampullary cancers include adenocarcinomas arising from the pancreas, ampulla of vater, duodenum or distal common bile duct. the exact site of origin ...

Research background: Despite a dynamically growing exploration of broadly understood employee participation, there is still space left for more in-depth or new analyses in this area, and occupational health safety (OHS) serves as good example respect. In empirical studies, participation the field not treated separate element ensuring organisation, but only minor management, just one elements bu...

Inspired by astonishing navigation ability of insects and other animals, many studies observed their behaviors, and considered biomimetic application to robotic systems by investigating mechanisms based on various senses. In this paper, we suggest a new landmark vector model for homing navigation with quantized distance information. The method is highly successful for homing navigation in both ...

INTRODUCTION Pain is one of the most prevalent unpleasant sensation in people that may significantly lower the quality of life. More than a half of cancer patients suffer from various forms of pain, which becomes more frequent and intense as disease progresses. OBJECTIVE The objective of the study was to assess the degree of pain control in patients diagnosed with breast, lung, colorectal and...

CONTEXT Sulfate is critical in the biotransformation of multiple compounds via sulfation. These compounds include neurotransmitters, proteoglycans, xenobiotics, and hormones such as dehydroepiandrosterone (DHEA). Sulfation reactions are thought to be rate-limited by endogenous sulfate concentrations. The gene, SLC13A1, encodes the sodium-sulfate cotransporter NaS1, responsible for sulfate (re)a...

Let g be a complex simple Lie algebra. Fix a Borel subalgebra b and a Cartan subalgebra t ⊂ b. The nilpotent radical of b is denoted by u. The corresponding set of positive (resp. simple) roots is ∆ (resp. Π). An ideal of b is called ad-nilpotent, if it is contained in [b, b]. The theory of ad-nilpotent ideals has attracted much recent attention in the work of Kostant, Cellini-Papi, Sommers, an...

BACKGROUND- Aspirin or dual antiplatelet therapy with aspirin and clopidogrel is a standard therapy for patients who are at increased risk for cardiovascular events. However, the genetic determinants of variable response to aspirin (alone and in combination with clopidogrel) are not known. METHODS AND RESULTS- We measured ex vivo platelet aggregation before and after dual antiplatelet therapy i...
