The correlation between renal histology and class specific (IgG IgM) antibodies to double stranded DNA (dsDNA) single (ssDNA) was studied by enzyme linked immunosorbent assay (ELISA) in 40 untreated patients with systemic lupus erythematosus (SLE). levels of IgG dsDNA were significantly higher World Health Organisation IV nephritis than those I, II, or III nephritis. ssDNA II showed a close the histological activity score amount electron dense deposit. only weak score. IgM not correlated...
Antiresorptive agent-related osteonecrosis of the jaw (ARONJ)/medication-related (MRONJ) include both bisphosphonate-related (BRONJ) and denosumab-related (DRONJ).

Abstract The Extended Electron Beam Ion Source (EEBIS) has been installed and commissioned at Brookhaven National Laboratory (BNL) hadron accelerator complex in the spring of 2023. EEBIS replaced its predecessor, RhicEBIS, which provided ions for BNL facilities over a decade since 2009. motivations source upgrade are to provide higher intensities Au 32+ ion beam Relativistic Heavy Collider (RHIC) an intense polarized 3 He 2+ future (EIC) BNL. is will continue be primary variety different...
Gradient-echo T2*-weighted magnetic resonance imaging (T2*-weighted MRI) is highly sensitive for detecting cerebral microbleeds (CMBs). CMBs have been reported to be a risk factor future cerebrovascular events and marker of small vessel disease in the general population. Chronic kidney (CKD) an independent cardiovascular disease. The relationship between CKD CMBs, which has not clarified date, examined.In this cross-sectional study, MRI brain was performed with 1.5-T system 162 patients (CKD...
The analyzing powers of ${\ensuremath{\pi}}^{+}$ and ${\ensuremath{\pi}}^{\ensuremath{-}}$ were measured using an incident $22\ensuremath{-}\mathrm{GeV}/c$ transversely polarized proton beam at the Brookhaven Alternating Gradient Synchrotron. A magnetic spectrometer ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ inclusive asymmetries on a hydrogen carbon target. An elastic polarimeter with ${\mathrm{CH}}_{2}$ target pp elastic-scattering to determine polarization published data for...
A coherent spin resonance excited by an rf dipole was used to overcome depolarization due intrinsic resonances at the Alternating Gradient Synchrotron (AGS) Brookhaven National Laboratory. We found that our data are consistent with a full flip of polarized proton beam, without emittance growth, $G\ensuremath{\gamma}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}12+{\ensuremath{\nu}}_{z}$ and $36\ensuremath{-}{\ensuremath{\nu}}_{z}$, adiabatically exciting vertical betatron oscillation...
To clarify the role of PDGF A-chain in hypertensive vascular hypertrophy spontaneously rats (SHRs), we studied levels gene expression and transcription factors related to smooth muscle cells (VSMCs) SHRs vivo. RNase protection assay situ hybridization showed that mRNA VSMCs were twofold higher than those normotensive Wistar-Kyoto rats. Gel retardation assays Sp1 AP-2 more abundant Treatment with four pharmacologically different species antihypertensive drugs for 2 wk decreased both Sp1, but...
As part of a new heavy ion preinjector that will supply beams for the Relativistic Heavy Ion Collider and National Aeronautics Space Administration Radiation Laboratory, construction electron beam source (EBIS) is now being completed. This source, based on successful prototype Brookhaven Laboratory Test EBIS, designed to produce milliampere level currents all species, with q/m=(1/6)−(1/2). Among major components this are 5 T, 2-m-long, 204 mm diameter warm bore superconducting solenoid, an...
Boron diffusion into silicon has been investigated by a closed tube method using elemental boron as the source. Amount of source, source temperature, and temperature are main parameters controlling surface concentration. It is presumably oxide formed oxidation that actually contributes to transfer in system. The coefficient given D =5.1exp (-85,000/ R T ), its concentration dependence examined. masking effect against also examined on basis two boundary model. smaller than three orders...

Pulse length extension of highly charged ion beam generated from a laser source is experimentally demonstrated. The (LIS) has been recognized as one the most powerful heavy source. However, it was difficult to provide long pulse beams. By applying solenoid field (90 mT, 1 m) at plasma drifting section, carbon reached 3.2 μs which 4.4 times longer than width conventional LIS. particle number ions accelerated by radio frequency quadrupole linear accelerator 1.2 × 1011, provided single J Nd-YAG...

Background: It is known that patients on hemodialysis (HD) are prone to developing zinc deficiency due removal of by HD, inadequate dietary intake, and reduced gastrointestinal absorption. However, the prevalence in peritoneal dialysis (PD) has not been well established. Methods: Serum levels were compared between 47 PD HD matched for age, sex, duration dialysis. A serum level < 60 μg/dL was defined as clinical a 60–80 subclinical deficiency. The associated factors determined both groups....
The idea of direct plasma injection scheme (DPIS) was proposed in 2000. This new technique has been studied and proven to accelerate intense ion beams. To provide medium mass ions with highly charged states, small tabletop solid lasers were used for production. Based on the measured properties, aluminum carbon accelerated more than 60 mA current. next experiments will use an radio frequency quadrupole designed q/m=1/6 explore beam productions using targets up silver, future work production...
