PURPOSE Due to their comorbidities, dialysis patients have many chances to undergo radiologic procedures using iodinated contrast media. We aimed to assess time-sequenced blood oxidative stress level after contrast exposure in hemodialysis (HD) patients compared to those in the non-dialysis population. MATERIALS AND METHODS We included 21 anuric HD patients [HD-coronary angiography (CAG) grou...

Mozambique continues to face many challenges in HIV and maternal and child health care (MCH). Community-based antiretroviral treatment groups (CAG) enhance retention to care among members, but whether such benefits extend to their families and to MCH remains unclear. In 2011 we studied utilization of HIV and MCH services among CAG members and their family aggregates in Changara, Mozambique, thr...

BACKGROUND Coronary angiography (CAG) is widely used to assess lumen dimensions, and optical coherence tomography (OCT) is used to evaluate the characteristics of atherosclerotic plaque. This study was aimed to compare coronary lumen dimensions using CAG and plaque characteristics using OCT and their changes during statin therapy. METHODS We identified 97 lipid-rich plaques from 69 statin-naï...

Chronic atrophic gastritis (CAG) is a process of inflammation characterized by injured gastric mucosal epithelium leading to reduction glands, often accompanied intestinal or pseudopyloric metaplasia. Astragalus polysaccharide (APS) reported improve damage and inflammation, but its role in CAG remains elusive. Therefore, we intended analyze the impact APS on potential mechanism provide novel in...

There is some evidence that women with a higher number of CAG repeat lengths on the androgen receptor (AR) gene have increased breast cancer risk. We evaluated the association between AR-CAG repeat length and mammographic density, a strong breast cancer risk factor, in 404 African-American and Caucasian breast cancer patients. In postmenopausal estrogen progestin therapy users, carriers of the ...

CAG/CTG repeats are structure-forming repetitive DNA sequences, and expansion beyond a threshold of ∼35 CAG repeats is the cause of several human diseases. Expanded CAG repeats are prone to breakage, and repair of the breaks can cause repeat contractions and expansions. In this study, we found that cotranscriptional R-loops formed at a CAG-70 repeat inserted into a yeast chromosome. R-loops wer...

Background. Improving methods of coronary artery disease (CAD) diagnosis involves determining the most informative and less expensive methods. Speckle tracking echocardiography (STE) is now widely used for early myocardial ischemia diagnosis, allowing better verification ambivalent results angiography (CAG).
 The aim. To develop algorithmic approaches to CAD through combined use STE CAG in...

Cycloastragenol (CAG) is the aglycone derivative of astragaloside IV which has recently been demonstrated to activate telomerase and represents a potential drug candidate for the treatment of degenerative diseases. In the present study, intestinal absorption and metabolism of CAG were examined using the Caco-2 model and liver microsomes, respectively. The results showed that CAG rapidly passes ...

OBJECTIVE To determine whether changes in the polymorphic trinucleotide (CAG) tract of the androgen receptor gene are associated with spermatogenic defects in patients with male infertility. DESIGN Case-control study of two ethnic groups. SETTING University referral centers for male infertility at Baylor College of Medicine, Houston, Texas, and National University Hospital, Singapore. PAR...

Helicobacter pylori cag pathogenicity island (PAI) is a major determinant of gastric injury via induction of several matrix metalloproteinases (MMPs). In the present study, we examined the influence of the cag PAI on gastric infection and MMP-9 production in mice and in cultured cells. A new mouse colonizing Indian H. pylori strain (AM1) that lacks the cag PAI was used to study the cag PAI impo...
