ABSTRACT BACKGROUND AND OBJECTIVES: Rheumatoid arthritis is a set of symmetrical inflammatory processes that affects the joints. Currently, drug therapy first choice for treatment disease, however it can cause serious side effects. In this context, photobiomodulation appears as potential resource treatment. Therefore, aim study was to analyze effects low intensity laser on pain and joint degene...

The role of the topological index, ZG, proposed by the present author in 1971, in various problems and topics in elementary mathematics is introduced, namely, (i) Pascal’s and asymmetrical Pascal’s triangle, (ii) Fibonacci, Lucas, and Pell numbers, (iii) Pell equation, (iv) Pythagorean, Heronian, and Eisenstein triangles. It is shown that all the algebras in these problems can be easily obtaine...

The main regulators of aldosterone secretion in adrenal gland zona glomerulosa (ZG) cells are the hormones angiotensin II (Ang II) and adrenocorticotrophin (ACTH) and small increases in the extracellular potassium (K(+)) concentration. The action of these agonists is mediated by different signalling systems - ACTH is mediated by cAMP and activation of protein kinase A while Ang II and K(+) acti...

A long-standing problem, posed first by Graham Higman in 1940 [Hi] and later by Brauer [Br], is the “isomorphism problem for integral group rings.” Given finite groups G and H, is it true that ZG N ZH implies G N H? Many authors have worked on this question but progress has been difficult [Sal. Perhaps the best positive result was that of Whitcomb in 1968 [Wh], who showed that the implication G...

in this paper, we introduce the new notion of n-f-clean rings as a generalization of f-clean rings. next, we investigate some properties of such rings. we prove that mn(r) is n-f-clean for any n-f-clean ring r. we also, get a condition under which the denitions of n-cleanness and n-f-cleanness are equivalent.

A group has homological dimension ≤ 1 if it is locally free. We prove the converse provided that G satisfies the Atiyah Conjecture about L -Betti numbers. We also show that a finitely generated elementary amenable group G of cohomological dimension ≤ 2 possesses a finite 2dimensional model for BG and in particular that G is finitely presented and the trivial ZG-module Z has a 2-dimensional reso...

LIEBOW, C., AND S. S. ROTHMAN. Transport of bovine chymotrypsinogen into rabbit pancreatic cells. Am. J. Physiol. 226(5) : 1077-1081. 1974.-Chymotrypsinogen uptake was measured into slices of rabbit pancreas incubated in bovine chymotrypsinogen-3H and albumin J311. Chymotrypsinogen uptake was 16 times greater than that for albumin. Chymotrypsinogen-3H was not readily “chased” by washing in cold...

The computation of the projective surgery obstruction groups LP.(ZG), for G a hyperelementary finite group, is reduced to standard calculations in number theory, mostly involving class groups. Both the exponent of the torsion subgroup and the precise divisibility of the signatures are determined. For G a 2-hyperelementary group, the LP.(ZG) are detected by restriction to certain subquotients of...

In pancreatic acinar cells Ca(2+)-dependent secretagogues promote the fusion of zymogen granules (ZG) with the apical plasma membrane (PM) and exocytosis of digestive enzymes. In addition to exocytotic fusion complexes between SNARE proteins in the ZG membrane (ZGM) and the apical PM, enzyme secretion elicited by Ca(2+)-dependent secretagogues requires cytosolic Cl and K+ and is inhibited by bl...
