The patient, a 45-year-old male, was referred to the rheumatology clinic due to diffuse joint pain on the wrists and knees. The patient was diagnosed with liver cirrhosis and severe hepatopulmonary syndrome. Physical examination showed swelling of the knees and wrists (arthritis) and clubbing. The X-rays requested showed periosteal thickening observed continuously, in a diaphysometaphysiary loc...

Open surgery for a type Ib endoleak after thoracic endovascular aortic repair is associated with some knacks and pitfalls, particularly in cases wherein the distal edge of a stent graft is located at just supraceliac aorta and the renovisceral segment and infrarenal aorta do not require surgical intervention. Here we describe the invaginated graft insertion technique to provide an easy and secu...

This paper is concerned with pronominal demonstatives (referred to as psychologically distal demonstratives by Johannessen 2008a, b) in older Norwegian spoken language, and written Swedish from the 19th century present-day. We show that can be attested speakers born different parts of Norway century, texts same period. However, forms do not seem used precisely way two languages. In Swedish, han...

Ultrastructural studies were conducted on biopsy specimens taken by endoscopy from the edge of gastric ulcers in the distal part of the stomach of 9 patients before and after treatment with either bicitropeptide or cimetidine. Marked depletion of mucin granules in the mucous epithelial cells and the pyloric gland cells was found in all patients and there was morphological evidence of a block in...

Enhancers govern transcription through multiple mechanisms, including the regulation of elongation by RNA polymerase II (RNAPII). We characterized the dynamics of looped enhancer contacts during synchronous transcription elongation. We found that many distal enhancers form stable contacts with their target promoters during the entire interval of elongation. Notably, we detected additional dynam...

Vibrotactile stimulation system that generates haptic illusion by employing a RA mechanoreceptor model is developed. The developed stimulator consists of an array of 6 by 4 tiny ultrasonic linear motors [1, 2] with nominal pitch of 2.9mm. Distal pad of human finger with RA mechanoreceptors is modeled using Bensmaia’s RA model [3]. In addition, stimulation characteristics of the motor are calibr...

 Abstract: This paper presents the results of an experimental examination of the effect of non-uniform wall temperature on local heat transfer coefficient in a rotating smooth-walled square channel. Three different thermal boundary situations were investigated: (a) even and odd (four) wall uniform temperature, (b) even and odd (four) wall uniform heat flux, and (c) even (leading and trailing) w...

The vertex-edge Wiener index of a simple connected graph G is defined as the sum of distances between vertices and edges of G. Two possible distances D_1(u,e|G) and D_2(u,e|G) between a vertex u and an edge e of G were considered in the literature and according to them, the corresponding vertex-edge Wiener indices W_{ve_1}(G) and W_{ve_2}(G) were introduced. In this paper, we present exact form...

‎For a coloring $c$ of a graph $G$‎, ‎the edge-difference coloring sum and edge-sum coloring sum with respect to the coloring $c$ are respectively‎ ‎$sum_c D(G)=sum |c(a)-c(b)|$ and $sum_s S(G)=sum (c(a)+c(b))$‎, ‎where the summations are taken over all edges $abin E(G)$‎. ‎The edge-difference chromatic sum‎, ‎denoted by $sum D(G)$‎, ‎and the edge-sum chromatic sum‎, ‎denoted by $sum S(G)$‎, ‎a...

BACKGROUND Arthroscopic treatment of tears in the middle and posterior parts of the medial meniscus can be difficult when the medial tibiofemoral compartment is tight. Passage of the instruments may damage the cartilage. The primary objective of this cadaver study was to perform an arthroscopic evaluation of medial tibiofemoral compartment opening after pie-crusting release (PCR) of the superfi...
