However, this procedure involves relatively high radiation dose. The purpose of thi...

The cyclin-dependent kinase (Cdk)-associated protein phosphatase KAP is a dual-specificity phosphatase of which the only known function is to dephosphorylate Cdk2 and inhibit cell cycle progression. Paradoxically, we find increased KAP mRNA expression in malignant astrocytomas, which correlates with increasing histologic grade and decreased patient survival. We have resolved this apparent parad...

Interventional cardiology is a medical specialty widely known to deliver high radiation dose to patients, who may receive, in some complex cases, skin doses over the threshold for deterministic effects. Because several studies have demonstrated large variability in delivered doses, European SENTINEL consortium has carried out a patient dose survey to propose regional Reference Levels (RL) as a ...

introduction: coronary angiography and angioplasty procedures lead to significant radiation exposure of patients. in the current study, the average radiation dose to patients during angiography in the angiography department of shahid-madani hospital was determined. materials and methods: an image intensifier based angiography unit (philips bh 3000) was used for angiography procedures. the accur...

introduction: in 2000, the unscear reported that ct constitutes 5% of all the medical x-ray  examinations and it contributes 34% of the resultant collective dose worldwide. children are more  sensitive to the ionizing radiations than adults. so, routine quality control tests are expected to be  carried out periodically on the ct scanners. the aim of this research was to estimate the effective  ...

The kerma-area product (PKA) is a useful quantity to establish the reference levels in diagnosis of conventional X ray examinations. A KAP meter can be calibrated in laboratory or in situ, where it is used. The patient dose calibrator (PDC) is a new equipment from Radcal that measures PKA. It was manufactured following the IEC 60580 recommendations. The aim of this study was to calibrate the PD...

Krüppel-associated box-containing zinc finger proteins (KRAB-ZFPs) repress transcription via functional interaction with the corepressor KRAB-associated protein-1 (KAP-1). KAP-1 directly interacts with heterochromatin protein 1 (HP1), a dose-dependent regulator of heterochromatin-mediated silencing. Here we show that two KRAB-ZFPs that we previously identified, KRAZ1 and KRAZ2, are targeted to ...

Coronary angiography (CA) procedure uses various angiographic projections to elicit detailed information of the coronary arteries with some steep projections involving high radiation dose to patients. This study intends to evaluate radiation doses and estimated risk from angiographic projections during CA procedure performed using novel flat detector (FD) system with improved image processing a...

CONTEXT Type 2 diabetes is the modern epidemic wherein patient care needs multiple approaches, education, and self-awareness being one of them. There are some knowledge, attitude, and practice (KAP) studies from India but very few relating it with disease control. AIMS We tried to study KAP of treated type 2 diabetics and its correlation with glycemic control. SETTINGS AND DESIGN Cross-sect...

BACKGROUND Literature suggests that radial access is associated with higher radiation doses than femoral access. AIMS To compare patient radiation exposure during coronary angiography (CA) and percutaneous coronary intervention (PCI) with radial versus femoral access. METHODS RAY'ACT is a nationwide, multicentre, French survey evaluating patient radiation in interventional cardiology. Varia...
