BACKGROUND AND PURPOSE The alteration of regional cerebral blood flow (CBF) during and after hyperventilation was measured using positron emission tomography (PET) to determine the circulatory response induced by daily respiratory changes in the cerebral area under chronic hemodynamic stress. METHODS Three normal volunteers and 12 patients with an obstruction of major cerebral arteries underw...

Many viruses have evolved mechanisms to evade host immunity by subverting the function of dendritic cells (DCs). This study determined whether murine gammaherpesvirus-68 (gamma HV-68) could infect immature or mature bone-marrow-derived DCs and what effect infection had on DC maturation. It was found that gamma HV-68 productively infected immature DCs, as evidenced by increased viral titres over...

Murine gammaherpesvirus 68 (gamma HV-68; also referred to as MHV-68) is a gammaherpesvirus which infects murid rodents. Previous studies showed that CD8 T cells are important for controlling gamma HV-68 replication during the first 2 weeks of infection and suggested a role for B cells in latent or persistent gamma HV-68 infection. To further define the importance of B cells and CD8 T cells duri...

OBJECTIVE High-viscosity hydroxypropylmethylcellulose (HV-HPMC) is a modified cellulose fiber that produces a viscous gel in the gastrointestinal tract. Clinical trials demonstrate that consumption of HV-HPMC significantly lowers cholesterol, but limited information has been available on the influence of HV-HPMC on postprandial insulin and glucose responses. The objective of this investigation ...

Using the Korean public health insurance database, we analyzed patients diagnosed as benign prostatic hyperplasia (BPH) from 2004 to 2008. Age and year-specific amount and seasonal variation of hospital visits (HV), duration of treatment (DT), the total and per capita amount of insurance payment (TAIP, PCIP) were evaluated. A total of 12,088,995 HV were studied. Total HV increased 1.7 times and...

The multitrait genetic evaluation system for type traits was modified to estimate adjustments for heterogeneous variance (HV) simultaneously with estimated breeding values (EBV) for final score and 14 linear traits. Each variance within herd, year, and parity was regressed toward a predicted variance, which was determined by fitting a model with fixed effects of the mean final score for herd, s...

Abstract We present a theory of turbulence elasticity, which follows from delayed response of drift waves (DWs) to zonal flow (ZF) shears. It is shown that when |hV iZF |/ !k > 1, with |hV iZF | the ZF shearing rate and !k the local turbulence decorrelation rate, the ZF evolution equation is converted from a di↵usion equation to a telegraph equation. This insight provides a natural framework fo...

BACKGROUND Hemorrhagic fever with renal syndrome (HFRS) is an important infectious disease in Hebei Province. At present, cases from the northeast regions of the province account for >80% of the total incidences. However, studies that examine the region-specific genetic variations of the Hantavirus (HV), the causative pathogen for HFRS, have been lacking. METHODS Rodents were collected in nor...

Hypoxic vasoconstriction (HV) is an intrinsic response of mammalian pulmonary vascular smooth muscle (VSM). In the present study, HV was examined by myography of vessel rings from three primitive vertebrates: New Zealand hagfish (NZH), Pacific hagfish (PH), and sea lamprey (SL). Hypoxia dilated pre-gill arteries (ventral aorta, afferent branchial) from all species, whereas it contracted systemi...

Efficient cell electrotransfection can be achieved using combinations of high-voltage (HV; 800 V/cm, 100 micros) and low-voltage (LV; 80 V/cm, 100 ms) pulses. We have developed equipment allowing the generation of various HV and LV combinations with precise control of the lag between the HV and LV pulses. We injected luciferase-encoding DNA in skeletal muscle, before or after pulse delivery, an...
