The purpose of this paper is to evaluate factors affecting the outcome of cholangitis after PTBD in jaundiced cancer patients. Twenty nine patients with neoplastic jaundice (male/female ratio 13/16, median age 55 years) with full clinical data, were treated by PTBD and developed cholangitis at a median of 9 days later. Four patients (14%) died of biliary sepsis a median of one month after PTBD ...

Two sublines of a breast epithelial cell culture, MCF-10, derived from human fibrocystic mammary tissue exhibit immortality after extended cultivation in low calcium concentrations (0.03-0.06 HIM)and floating transfers in low calcium (MCF-10F), or by trypsin-Versene passages in the customary (normal) calcium levels, 1.05 HIM (MCF-10A). Both sublines have been maintained as separate entities aft...

Recovered Energy Logic (REL) is a new family of logic that charges and discharges capacitive logic nodes in an ideally lossless fashion. To accomplish this, REL uses an AC waveform as both the system power supply and a two-phase clock. Unlike mainstream logic circuits, REL circuits require substantial current from all three terminals of a transistor. This makes BJTs and MESFETs a natural choice...

Carcinogenesis is a multi-stage process with sequence of genetic events governing the phenotypic expression of a series of transformation steps leading to the development of metastatic cancer. In the present study, immortalized human bronchial (BEP2D) and breast (MCF-1 OF) cells were irradiated with graded doses of either 150 keV/ktm alpha particles or 1 GeV/nucleon SrFe ions. Transformed cells...

PURPOSE To evaluate a new calculation model estimating the equivalent dose at 2 Gy (EQD2) taking into account dose gradient in high dose rate interstitial brachytherapy (HDRIB). MATERIAL AND METHODS Forty dose-volume histograms (DVHs) of breast (20 pts) and prostate (20 pts) cancer dose distributions were reviewed. Physical prescribed doses (PPD) were 34 Gy (10f/5d) and 18 Gy (6f/2d) for brea...

Ultrasound examinations of the heart and major peripheral arteries have been performed as separate procedures; both potentially limited by suboptimal views in certain subjects and the inability to obtain ideal pictures of particular intracardiac structures. Transvenous ultrasound may offer new advantages in certain areas, we therefore studied six adult baboons using a single-plane 5.5-10 MHz tr...

OBJECTIVE Neochordae implantation is a standard method for treatment of mitral valve prolapse. We describe a transcatheter technology enabling transapical endovascular chordal implantation. METHODS Six adult pigs were anesthetized. Two 10F sheaths were introduced in the femoral vessels for monitoring and intracardiac echo. After midline sternotomy, the pericardium was opened, the apex was pun...

The histograms of user ratings (1F, . . . , 10F) on the Internet Movie Database (IMDb.com) which are in a mature state (more than 20, 000 ratings) seem to follow common rules. All are either double or triple peaked. Moreover, at most one peak can be on the central bins 2F, . . . , 9F and the distribution in these bins looks smooth `Gaussian-like' while changes at the extremes the often look abr...

This study was carried out to investigate the genetic polymorphism of nine short tandem repeat (STR) loci including D2S1772, D6S1043, D7S3048, D8S1132, D11S2368, D12S391, D13S325, D18S1364 and D22GATA198B05 in Chinese Han population of Henan province and to assess its value in forensic science. Genomic DNA was extracted by means of phenol-chloroform from 212 blood samples of unrelated healthy i...

Breast cancer is the most frequent malignancy in women. It is well recognized that tumorigenesis is a multistep process resulting from the accumulation of sequential genetic alterations. In breast cancers LOH has been described on one or both arms of multiple chromosomes. Comparative genomic hybridization (CGH) analysis was performed to identify chromosomal imbalances in the breast epithelial c...
