The delay eyeblink conditioning (EBC) is a cerebellum-dependent type of associative motor learning. However, the exact roles played by the various cerebellar synapses, as well as the underlying molecular mechanisms, remain to be determined. It is also unclear whether long-term potentiation (LTP) or long-term depression (LTD) at parallel fiber (PF)-Purkinje cell (PC) synapses is involved in EBC....

The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987–1993) within images of satellite-derived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF that strongly affect spatial and temporal variability. Over the deep ocean basins...

OBJECTIVES This study was conducted to investigate the effects of thyroid hormone on the electrophysiological characteristics of pulmonary vein (PV) cardiomyocytes. BACKGROUND Hyperthyroidism is an important etiology of paroxysmal atrial fibrillation (AF). Pulmonary veins are known to initiate paroxysmal AF. METHODS The action potential and ionic currents were investigated in single rabbit ...

HYPOTHESIS Pancreatic fistula (PF), a common and potentially lethal complication of pancreaticoduodenectomy, can be managed nonoperatively in most cases. DESIGN Retrospective case series. SETTING Major academic medical and pancreatic surgery center. PATIENTS A total of 437 consecutive patients who underwent pancreaticoduodenectomy for various diagnoses between January 1, 1988, and August ...

INTRODUCTION Since the criteria of Light and colleagues for differentiating transudates and exudates were described, other tests, including the pleural fluid (PF) cholesterol test, have been proposed for the same purpose. However, the factors influencing PF cholesterol levels have not been clearly delineated. PURPOSE To analyze the relationships among total cholesterol (CHOL), low-density lip...

RATIONALE A chromosomal haplotype producing cardiac overexpression of dipeptidyl peptidase-like protein-6 (DPP6) causes familial idiopathic ventricular fibrillation. The molecular basis of transient outward current (I(to)) in Purkinje fibers (PFs) is poorly understood. We hypothesized that DPP6 contributes to PF I(to) and that its overexpression might specifically alter PF I(to) properties and ...

OBJECTIVE To develop a new polycystic ovary syndrome (PCOS) rat model suitable for exercise intervention. METHOD Thirty six rats were randomly divided into three experimental groups: PCOS rats with high-fat diet (PF, n = 24), PCOS rats with ordinary diet (PO, n = 6), and control rats with ordinary diet (CO, n = 6). Two kinds of PCOS rat model were made by adjustment diet structure and testost...

In this paper, PF(#P) is characterized in a similar manner to Krentel’s characterization [I<re88] of PF(NP). Let MidP be the class of functions that give the medians in the outputs of metric Turing machines. Then it is shown that every function in PF(#P) is polynomial time 1Turing reducible to a function in MidP and MidP PF(#P); that is, PF(#P) = PF(MidP[l]). Intuitively speaking, finding media...

INTRODUCTION Characteristics of prostatic fluid (PF), which can be obtained in large amounts during screening transrectal ultrasound just before prostate biopsy to detect prostate cancer, were investigated. These characteristics include the amount of PF obtained and the number of leukocytes in PF, which would be useful for planning cell-biological or immunological studies of leukocytes in PF an...
