Geriatric Trauma Patients: Outcomes Before and After Addition of a Hospitalist Consultation.

Background: Research has shown improvements in patient care and outcomes with addition of a rounding geriatrician. The purpose of this study was to determine if addition of a hospitalist consultation improved patient outcomes.

Methods: A retrospective review was conducted of all trauma patients, ≥65 years, before (n=481) and after (n=430) addition of a hospitalist consultant.

[Construction of recombinant human nerve growth factor (rh-β-NGF) eukaryotic vector and its expression in HEK293 cells].

Human nerve growth factor (NGF) is a nerve cell growth regulation factor, which can provide nutrition for the neurons and promote the neurites outgrowth. In order to produce large-scale recombinant human nerve growth factor (rh-beta-NGF), we constructed a plasmid vector, which can stably express the rh-beta-NGF in the HEK293 cell lines. First, the plasmid of pCMV-beta-NGF-IRES-dhfr was constructed and transformed into HEK293 cells.

Real time monitoring of hazardous airborne chemicals: a styrene investigation.

The low level detection of air pollutants requires reliable sampling and calibration techniques, as well as using sophisticated analytical instrumentation. Incorporating these requirements into a mobile platform allows for accurate, curb side measurement of airborne ambient chemicals in real time. In this case study, air emissions from two manufacturing facilities in close proximity to each other were monitored with a mobile unit to chemically characterize and differentiate the emissions from each facility.

Extraordinary cluster formation and intramolecular ligand-ligand interactions in cyanoacetylene [corrected] mediated by Mg+*: implications for the atmospheric chemistry of titan and for circumstellar chemistry.

Experimental results are reported that track the kinetics of gas-phase reactions initiated by Mg+*, (c-C5H5)Mg+ and (c-C5H5)2Mg+* in hydrogen cyanide and cyanoacetylene. The experiments were performed with a selected-ion flow tube (SIFT) tandem mass spectrometer at a helium buffer-gas pressure of 0.35 +/- 0.

Air monitoring of a coal tar cleanup using a mobile TAGA LPCI-MS/MS.

Real-time detection of air toxics is becoming increasingly important in understanding the sources and constituents of air pollution. The detection of low levels of air contaminants requires reliable sampling and calibration techniques, as well as sophisticated analytical instrumentation. Recently, a new low pressure chemical ionization (LPCI) source was developed for ambient air monitoring of benzene, toluene, xylene (BTX) and gas-phase polycyclic aromatic hydrocarbons (PAH) in real-time.
