We aimed to determine normal reference ranges for prostate volume (PV) and annual PV change rate in a Korean nationwide screening population. Data from men who underwent a routine health check-up were collected from 13 university hospitals. The cohort comprised men aged ≥40 yr who had undergone 2 or more serial transrectal ultrasonographies. Men with initial PV>100 mL; serum PSA level>10 ng/mL;...

Conversion of CO2 into valuable compounds, including fuels, with renewable energy sources and sustainable compounds is a challenge addressed by artificial photosynthesis research. In particular, the application solar assisted electrochemical (EC) processes, in which electrons are furnished photovoltaic (PV) cell, promising approach. A PV-EC system described, consisting CIGS (copper indium galli...

This paper studies the possibilities of decomposition of the current in three-phase, three-wire systems based on the classic p-q theory. Recently, the energy crisis in the world has led to the rise in use of renewable energy sources with the advancement in power electronics technology, the solar photovoltaic energy has been recognized as an important renewable energy resource because it is clea...

BACKGROUND Staphylococcus aureus produces several toxins, including Panton-Valentine leukocidin (PVL). The involvement of PVL in primary skin infections, necrotizing pneumonia, musculoskeletal disorders, brain abscess, and other diseases, some of which are life-threatening, has been reported. Following expert opinion, we aimed to provide the tools for establishment of sequence-based diagnostics...

The market for photovoltaic (PV) energy systems is expanding rapidly in the U.S. Almost 100,000 PV systems have been installed in California alone, more than 90% of which are residential. Some of those “PV homes” have sold, yet little research exists estimating if those homes sold for significantly more than similar non-PV homes. A clearer understanding of these effects might influence the deci...

BACKGROUND Panton-Valentine leucocidin is a Staphylococcus aureus virulence factor encoded by lukF-PV and lukS-PV that is infrequent in S aureus bacteremia (SAB), and, therefore, little is known about risk factors and outcome of lukF-PV/lukS-PV-positive SAB. METHODS This report is a register-based nationwide observational cohort study. lukF-PV was detected by polymerase chain reaction. Factor...

INTRODUCTION There are currently no studies systematically evaluating pulmonary vein (PV) stenosis following catheter ablation of atrial fibrillation (AF) using the anatomic PV ablation approach. METHODS AND RESULTS Forty-one patients with AF underwent anatomic PV ablation under the guidance of a three-dimensional electroanatomic mapping system. Gadolinium-enhanced magnetic resonance (MR) ima...

The maximum power point tracking (MPPT) is used in photovoltaic system to maximize the photovoltaic array output power , irrespective of temperature , IR radiation, conditions and electrical characteristics of the load. A new MPPT system is developed consisting of DC to DC converter, which is controlled by microcontroller based unit. There are two charging stages for the proposed PV charger. At...

Recent studies indicate that the basolateral amygdala exhibits fast rhythmic oscillations during emotional arousal, but the neuronal mechanisms underlying this activity are not known. Similar oscillations in the cerebral cortex are generated by a network of parvalbumin (PV)-immunoreactive interneurons interconnected by chemical synapses and dendritic gap junctions. The present immunoelectron mi...

it to 680•Ž in flowing nitrogen (PV-7). Four samples having different pre-heat-treatment conditions were selected; the original coke PV-7 , the second one prepared from PV-7 by the heat treatment at 1500•Ž for 60 min (PV-15) , the third also from PV-7 by the treatment at 2060•Ž for 60 min (PV-7-20) , and the fourth by the heat treatment of PV-15 at 2060•Ž for 60 min (PV-15-20). Each sample was ...
