OBJECTIVE The anti-inflammatory proteins annexin-A1 and galectin-1 have been associated with tumor progression. This scenario prompted us to investigate the relationship between the gene and protein expression of annexin-A1 (ANXA1/AnxA1) and galectin-1 (LGALS1/Gal-1) in an inflammatory gastric lesion as chronic gastritis (CG) and gastric adenocarcinoma (GA) and its association with H. pylori in...

Several pituitary hormones are important in the regulation of metabolism, and their release appears to be controlled by a circadian clock. Consequently, they may be involved in feeding-entrained circadian rhythms. Hypophysectomized (Hypox) and sham-operated male Sprague-Dawley rats had access to food for 4 h each day. Food-anticipatory activity (FAA) and core body temperature (Tb) were monitore...

The glycogen in the liver cannot rise above 15 % and it is stated in textbooks that the capacity of muscle to store glycogen is limited. It would be considered unlikely that this total store could be more than doubled. Hence, if an individual consumed 400 g of carbohydrate in excess of his energy requirements, then it would be expected that there would be a net conversion of carbohydrate into f...

We introduce a new Krylov subspace iteration for large scale eigen-value problems that is able to accelerate the convergence through an inexact (iterative) solution to a shift-invert equation. The method also takes full advantage of an exact solution when it is possible to apply a sparse direct method to solve the shift-invert equations. We call this new iteration the Truncated RQ iteration (TR...

New diagnostic tools for early detection of leprosy are necessary to help reduce its transmission and severity. M. leprae unique proteins have been used to assess differences in human T-cell responses in leprosy patients, household contacts and endemic controls. In this study, we examined the response of M. leprae-infected armadillos to a variety of M. leprae recombinant antigen candidates curr...

Indirect calorimetry involves measurement of CO(2) produced and O(2) consumed by an organism. These measurements are then used to calculate energy output, metabolic rate (MR), and respiratory quotient (RQ), a relative assessment of carbohydrate and lipid oxidation. By far the most difficult aspect of indirect calorimetry is measurement of O(2). Moreover, the abundance of O(2) (20.95%) relative ...

The absolute change in the Rayleigh quotient (RQ) is bounded in this paper in terms of the norm of the residual and the change in the vector. If x is an eigenvector of a self-adjoint bounded operator A in a Hilbert space, then the RQ of the vector x, denoted by (x), is an exact eigenvalue of A. In this case, the absolute change of the RQ j(x) (y)j becomes the absolute error for an eigenvalue (x...

Several members of the transient receptor potential (TRP)-channel family are expressed in cancer cells. One, cold/menthol-sensitive TRPM8, is reportedly an important player in carcinogenesis in human prostate cancer, although its involvement in oral squamous cell carcinoma (SCC) remains unclear. The present immunohistochemistry and RT-PCR results ...
