The distribution coefficient (Kd) of Rf on ion exchange resins at various HNO3/HF concentrations had been studied [1]. Rf was eluted at higher HF concentrations from CIX than Zr and Hf and rather resembled Th. Up to 1 M HF, Rf was not retained on the AIX also resembling its pseudo-homolog Th. Th is known to form no anionic fluoride complexes, while Zr and Hf are forming complexes of the type [M...

Most UNC-104/KIF1 kinesins are monomeric motors that transport membrane-bounded organelles toward the plus ends of microtubules. Recent evidence implies that KIF1A, a synaptic vesicle motor, moves processively. This surprising behavior for a monomeric motor depends upon a lysine-rich loop in KIF1A that binds to the negatively charged carboxyl terminus of tubulin and, in the context of motor pro...

PURPOSE To investigate the levels of human telomerase reverse transcriptase (hTERT) DNA in the plasma of patients with hepatocellular carcinoma (HCC), and to evaluate the diagnostic value and correlation of hTERT DNA with clinical parameters in HCC. METHODS A real-time quantitative fluorescent polymerase chain reaction (FQ-PCR) system was designed and evaluated. Plasma samples were collected ...

Androgen ablation therapy is the primary treatment for metastatic prostate cancer. However, 80-90% of the patients who receive androgen ablation therapy ultimately develop recurrent tumors in 12-33 months after treatment with a median overall survival time of 1-2 years after relapse. LNCaP is a commonly used cell line established from a human lymph node metastatic lesion of prostatic adenocarci...

BACKGROUND While specific patterns of circulating dendritic cells (DCs) and monocytes are associated with the incidence of coronary artery disease, the characterization of circulating DC and monocyte subsets in patients with different stages of atherosclerosis remains unclear. METHODS Forty-eight patients with unstable angina pectoris (UAP) diagnosed by angiography were enrolled. Likewise, 31...

The aim of this study was to enumerate the bacterial population isolated from environmental surfaces in child-care centres Omoku and Port Harcourt, Nigeria. Four Nigeria were selected for samples different (Table, play mat, toilet seat, feeding area, diaper changing toys, window door handle surfaces) using sterile swab sticks moistened with peptone water. Aliquots 0.1 ml 103 dilutions inoculate...

Several studies have reported that polychlorinated biphenyls (PCBs) exhibit estrogenic activity; however, it is not clear if these responses are associated with the polychlorinated hydrocarbon or its hydroxylated metabolite. In order to further test this hypothesis, a battery of in vitro and in vivo assays were used to investigate the estrogenic and antiestrogenic activities of 2,4,6,2',6'-pent...

A noncovalent complex of the apoprotein (1-104) and cyanogen bromide heme fragment containing residues 1 to 65, (1-65) H, has been prepared from horse heart cytochrome c. Conditions under which the redundant portions of the ferrous complex can be removed by limited trypsin digestion have been devised. The complementing fragments have been isolated from the derived complexes and four apofragment...

UNC-104 (KIF1A) is a kinesin motor that transports synaptic vesicles from the neuronal cell body to the terminal. Previous in vitro studies have shown that a Dictyostelium relative of UNC-104 transports liposomes containing acidic phospholipids, but whether this interaction is needed for the recognition and transport of synaptic vesicles in metazoans remains unexplored. Here, we have introduced...
