A radio frequency-free electromagnetostatic (EMS) cell devised for electron-capture dissociation (ECD) of ions has been retrofitted into the collision-induced dissociation (CID) section of a triple quadrupole mass spectrometer to enable recording of ECD product-ion mass spectra and simultaneous recording of ECD-CID product-ion mass spectra. This modified instrument can be used to produce easily...

The aims were to develop a liquid chromatographic (LC) method with ultraviolet detection (UVD) for O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) O-oximes of common aldehydes and ketones, and to define the steric limits of the synthetic reaction used to make the PFBHA O-oxime standards for gas chromatographic (GC) and LC methods. Ten new O-oximes were synthesized with the ne...

The rate and extent of degradation of Aroclor 1242 from contaminated surface soil was investigated, using aceticlastic mathanogenic consortia enriched from municipal anaerobic digester. Two different experiments, “intermediate feed” and “starve and feed” were conducted using triplicate 160-mL serum bottle microcosms, containing either 0.1 g, 1 g, 10 g, or 50 g of soil plus 100 mL of the inoculu...

Depression is generally a recurrent psychiatric disorder. Evidence shows that depression and cardiovascular diseases are common comorbid conditions, but the specific pathological mechanisms remain unclear. The purpose of this study is to determine the effects of depression induced by chronic unpredictable mild stress (CUMS) on myocardial injury and to further elucidate the biological mechanism ...

Analytical methods for the analysis of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) are widely available and are the result of a vast amount of environmental analytical method development and research on persistent organic pollutants (POPs) over the past 30-40 years. This review summarizes procedures and examines new approaches for extraction, isolation, identification ...

The article aims to highlight one of the highest environmental issues, caused by pollution with persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs). This form a negative impact on human health would not be possible without use high voltage industrial electrical equipment dielectric fluids infested various PCB isomers. In order carry out experimental program, samples bo...

BACKGROUND Little is known about the incidence and risk factors of early consciousness disorder (ECD) in patients with acute ischemic stroke, or about how ECD may affect complications and outcomes. METHODS Patients admitted to our hospital within 24 h of onset of acute ischemic stroke were consecutively enrolled. ECD was evaluated clinically and using the Glasgow coma scale. Multivariate anal...

To evaluate the usefulness of a combination of linearization and scatter-attenuation correction on 99mTc-bicisate (ECD)-single photon emission tomographic (SPECT) images, both cerebral blood flow (CBF)-positron emission tomographic (PET) images and ECD-SPECT images from fifteen patients with chronic cerebral infarction were acquired. We measured radioactivity counts in regions of interest (ROIs...

Survival analysis is often used to compare experimental and conventional treatments. In observational studies, the therapy may change during follow-up and such crossovers can be summarized by time-dependent covariates. Given the ever-increasing donor organ shortage, higher-risk kidneys from expanded criterion donors (ECD) are being transplanted. Transplant candidates can choose whether to accep...
