A series of 60 gastric endocrine tumors comprised 44 body-fundus argyrophil carcinoids, of which 23 arose in a background of hypergastrinemia and type A chronic atrophic gastritis (A-CAG), mainly with histologic patterns suggestive of an autoimmune process. Only 22 percent (compared with 19 percent of 58 tumor-free A-CAG cases) of 36 carcinoids and 21 percent of 19 A-CAG carcinoids investigated...

the mitochondrial dna (mtdna) may play an essential role in the pathogenesis of the respiratory chain complex activities in neurodegenerative disorders such as huntington’s disease (hd). research studies have been conducted to determine the possible levels of mitochondrial defect (deletion) in hd patients and the interaction between the expanded huntingtin gene as a nuclear gene and mitochondri...

New mutations for Huntington disease (HD) arise from intermediate alleles (IAs) with between 29 and 35 CAG repeats that expand on transmission through the paternal germline to 36 CAGs or greater. Using single sperm analysis, we have assessed CAG mutation frequencies for four IAs in families with sporadic HD (IANM) and IAs ascertained from the general population (IAGP) by analyzing 1161 single s...

Background: The advantages of cyanoacrylates in cutaneous wound closure have been wi­ dely demonstrated in the literature. However, these products have not been widely used in Brazil due to the high costs of octyl cyanoacrylates. Moreover, there have been only a few studies on the most affordable product, ethyl cyanoacrylate, as a cutaneous adhesive. The objective of this study was to evaluate ...

The length of the polymorphic CAG trinucleotide repeat in the polyglutamine region of the androgen receptor (AR) gene is inversely correlated with the transactivation function of the AR. Because increased androgenic activity has been linked to prostate cancer and because an ethnic variation exists in the CAG repeat length, this polymorphism has been suggested to explain part of the substantial ...

As one of the main active ingredients from Radix Astragali (RA), orally dosed astragaloside IV (AST) is easily transformed to sapogenin-cycloastragenol (CAG) by deglycosylation in the gastrointestinal tract. Because the potential adverse effects of AST and CAG remain unclear, the present study in this article was carried out to investigate the inhibition effects of AST and CAG on UDP-glucuronos...

The Helicobacter pylori chromosomal region known as the cytotoxin-gene associated pathogenicity island (cag PAI) is associated with severe disease and encodes proteins that are believed to induce interleukin (IL-8) secretion by cultured epithelial cells. The objective of this study was to evaluate the relationship between the cag PAI, induction of IL-8, and induction of neutrophilic gastric inf...

ACTH infusion at the time of unilateral adrenalectomy inhibits the early rapid compensatory growth (CAG) in the remaining adrenal. We examined the hypothesis that different duration of surgery and/or the enhanced response to the stress of surgery, induced by estradiol treatment, might modify CAG. Adult male rats untreated, estradiol benzoate treated (EB) 300 microg/kg or vehicle treated (VE) fo...

Huntington's disease (HD) is a neurodegenerative disorder associated with expansion of CAG trinucleotide repeats in the huntingtin gene. A minimum of 36 CAG repeats is usually reported in patients with clinical features of HD; 30 to 35 repeats represent an intermediate range. Here we report a 65-year-old male with autopsy-proven HD and 29 CAG repeats.
