Yeast TGN resident proteins that frequently cycle between the TGN and endosomes are much more slowly transported to the prevacuolar/late endosomal compartment (PVC) than other proteins. However, TGN protein transport to the PVC is accelerated in mutants lacking function of Inp53p. Inp53p contains a SacI polyphosphoinositide phosphatase domain, a 5-phosphatase domain, and a proline-rich domain. ...

OBJECTIVES We sought to clarify the prevalence and characteristics of idiopathic ventricular tachycardia or premature ventricular contraction originating from the mitral annulus (MAVT/PVC). BACKGROUND Recent case reports have presented patients with MAVT/PVC. METHODS Electrocardiographic (ECG) characteristics and the results of electrophysiologic investigation and radiofrequency catheter ab...

The development of ion-selective microelectrodes for monitoring lithium ions in blood or serum is very important in the field of clinical chemistry. For this interest, all-solid-state microsensors based on impedance measurement for the detection of Li+ has been developed. The selective PVC membrane composition used was obtained by dissolving 1.2 % (w/w) Lithium ionophore III, 66 % (w/w) o-nitro...

Aquaporin 1 (AQP1) is a water channel protein expressed in endothelial and epithelial cells of many tissues, including the vasculature, where it serves to increase water permeability of the cell membrane. The aim of this study was to investigate the expression and distribution of AQP1 in porcine peri-ovarian vascular complex (PVC) during the estrous cycle and early pregnancy. Immunohistochemist...

INTRODUCTION Amyloid positron-emission tomography (PET) imaging with 11C-Pittsburgh compound B (PiB) is an effective tool for assessing brain amyloid deposits. PET imaging, however, can suffer from the partial volume effect (PVE). PVE has been corrected using MRI (magnetic resonance imaging) image data. However, correction of the PVE of PET using MRI usually requires two separate procedures, im...

The potentiometric response characteristics and analytical applications of a poly(vinyl chloride) (PVC)-free all-solid-state ion-selective electrode for chlorhexidine (CHX) are examined and compared to those of PVC-based solid-state electrode. The PVCfree electrode is prepared by direct incorporation of chlorhexidine-tetraphenyl borate (CHXTPB) as a sensing element into a commercial nail varnis...

INTRODUCTION Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to id...

A cobalt(II) derivative was used as a suitable ionophore for the preparation of a polymeric membrane nitrite-selective electrode. The electrode reveals a Nemstian behavior over a very wide NO2- ion concentration range (1.0 x 10(-6)-1.0 x 10(-1) M) and a very low detection limit (5.0 x 10(-7) M). The potentiometric response is independent of the pH of solution in the pH range 4.0-9.5. The electr...

A novel prepared mercuric ion PVC membrane sensor based on a Rhodamine B derivative (RND) as a selective sensing material was described. The sensor exhibited a specific fluorescent off-on response to Hg(2+), and showed a linear response over the Hg(2+) concentration range from 1.0 × 10(-9) to 2.0 × 10(-3)M with a very low detection limit of 8.1 × 10(-10)M in bulk method. The sensor has also bee...

Bacteria from the Planctomycetes, Verrucomicrobia, and Chlamydiae (PVC) superphylum are exceptions to the otherwise dominant mode of division by binary fission, which is based on the interaction between the FtsZ protein and the peptidoglycan (PG) biosynthesis machinery. Some PVC bacteria are deprived of the FtsZ protein and were also thought to lack PG. How these bacteria divide is still one of...
