Aspirated fasting gastric juice from patients with lesions of the gastrointestinal tract and from healthy controls was analysed for nitrite before and after (30, 90, and 240 min) oral administration of 200 mg nitrate. Wilcoxon's rank-sum tests showed no significant differences in fasting gastric

p53 codon 72, which produces variant proteins with an arginine (Arg) or proline (Pro), has been reported to be associated with cancers of the lung, esophagus and cervix. However, there have been no reports on the p53 codon 72 polymorphism in gastric cancer susceptibility in patients with

Helicobacter pylori is cause of chronic gastritis, duodenal ulcer and gastric carcinoma in humans. L-proline is a preferred energy source of the microaerophilic bacterium. Previous analyses revealed that HpputP and HpputA, the genes that are predicted to play a central role in proline metabolism as

Objective: Since early diagnosis is very important for treating gastric cancer (GC), we aimed to detect serum small proline-rich protein2A (SPRR2A) to verify its diagnostic value for GC patients.
Methods:
Antigenic proteins of Helicobacter pylori of potential diagnostic value.

Helicobacter pylori antigen was prepared from an isolate from a patient with a duodenal ulcer. Serum samples were obtained from culture-positive H. pylori infected patients with duodenal ulcers, gastric ulcers and gastritis (n=30). As controls, three kinds of sera without detectable H. pylori IgG

Codon 72 polymorphism of the tumor suppressor gene TP53 has been associated with a higher risk in the development of several types of cancer. The polymorphism results in a variant protein with either an arginine (CGC) or a proline residue (CCC). The aim of this study was to analyze the association

N-nitrosoproline (NPRO) excretion, an indicator of endogenous nitrosation, was measured in a group of hospital inpatients who were identified by endoscopy and gastric biopsy as either having gastric lesions or having healthy stomachs. NPRO was assayed in background 24-hour urine samples and samples

OBJECTIVE
To investigate Helicobacter pylori (H. pylori) CagA diversity and to evaluate the association between protein polymorphisms and the occurrence of gastric pathologies.
METHODS
One hundred and twenty-two clinical isolates of H. pylori cultured from gastric biopsies obtained from Colombian

OBJECTIVE
Mutations in the codon 72 of exon 4 in the p53 gene have been associated with higher risk in the development of several types of cancer. This polymorphism occurs with two alleles encoding either arginine (CGC) or proline (CCC). The aim of this study was to assess the role of the codon 72

The hypothesis that endogenous chemical nitrosation in the normal stomach in early life could play a crucial role in inducing chronic atrophic gastritis/intestinal metaplasia in later life was tested by applying the N-nitrosoproline (NPRO) test to 12-h urine samples from about 50 children (aged 8-14

The concentrations of free D- and L-amino acids were determined in the gastric juice from four groups: patients suffering from early gastric carcinoma with or without Helicobacter pylori infection, and patients without carcinoma but with peptic ulcers, duodenal ulcers or chronic gastritis with or

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; OMIM *240300, also called APS 1,) is a rare autosomal recessive disorder that is more frequent in certain isolated populations. It is generally characterized by two of the three major clinical symptoms that may be present,

BACKGROUND
Deletion or functional loss of the p53 tumor suppression gene plays a role in oncogenic transformation. The codon 72 polymorphism on exon 4 in the p53 gene produces variant proteins with either arginine (Arg) or proline (Pro), and is associated with an increased susceptibility of cancers

Green tea extract (GTE) inhibits obviously gastrointestinal malignant tumors in rats induced by N-methyl-N'-nitro-n-nitrosoguanidine (MNNG). The incidence of tumor was 93.3% in the MNNG positive control group, whereas 53.3% in the MNNG plus GTE group (P < 0.01). The percentage of inhibiting tumor

The development of intestinal gastric carcinoma involves several precancerous stages. The environmental factor plays an important role in gastric carcinogenesis, while the host's genetic makeup may influence the susceptibility to cancer. In this study we investigated correlations of the p53
