Introduction: Gemcitabine-based regimens are effective salvage therapy for RR lymphoma patients eligible for ASCT, but there is limited data in transplant-ineligible (TIE) patients. Here, we present a retrospective analysis on the outcome of TIE adult patients with RR lymphoma treated with gemcitabine, cisplatin or carboplatin and dexamethasone (GDP/GDCarboP) +/- rituximab regimen in our center.

Patients: We identified 33 patients: 54.

Aim: To review sudden unexpected infant deaths (SUDI) in the first 28 days of life referred to a Coronial Perinatal Forensic Pathology Service over a 10-year period from 2000 to 2009.

Methods: Cases were collected from mortuary records, and a retrospective review of autopsy reports and other available infant records was undertaken.

Results: Twenty-four neonatal SUDI were reviewed.

A key characteristic of the analyte-reporter enzyme conjugate used in the enzyme-multiplied immunoassay technique (EMIT) is the inhibition of the conjugate enzyme upon anti-analyte antibody binding. To improve our understanding of the antibody-induced inhibition mechanism, we characterized morphine-glucose-6-phosphate dehydrogenase (G6PDH) conjugates as model EMIT analyte-reporter enzyme conjugates. Morphine-G6PDH conjugates were prepared by acylating predominantly the primary amines on G6PDH with morphine 3-glucuronide NHS ester molecules.

A convenient homogeneous enzyme immunoassay for estradiol is described. Unlike heterogeneous immunoassays, which require time-consuming separation steps or expensive automated systems, homogeneous immunoassays, wherein all reagents are freely suspended in bulk solution, can be simple and fast without costly instrumentation. The key component of this assay system, an estradiol-reporter enzyme conjugate, was prepared by covalently binding β-estradiol-6-(O-carboxymethyl)oxime to glucose-6-phosphate dehydrogenase (G6PDH) by an N-hydroxysuccinimide-enhanced, carbodiimide-mediated coupling reaction.

A practical approach for constructing enzyme-multiplied immunoassay technique (EMIT)-based protein/peptide assays is described. Normally used in small-molecule drug testing, EMIT is a homogeneous assay method that is attractive for its simplicity, sensitivity, and rapidity. The EMIT-based peptide/protein assay was developed by conjugating a cysteine-modified HA peptide (from influenza hemagglutinin A) to the reporter enzyme, glucose-6-phosphate dehydrogenase.

The adsorption and hydrogenation of acrolein on the Ag(111) surface has been investigated by high resolution synchrotron XPS, NEXAFS, and temperature programmed reaction. The molecule adsorbs intact at all coverages and its adsorption geometry is critically important in determining chemoselectivity toward the formation of allyl alcohol, the desired but thermodynamically disfavored product. In the absence of hydrogen adatoms (H(a)), acrolein lies almost parallel to the metal surface; high coverages force the C=C bond to tilt markedly, likely rendering it less vulnerable toward reaction with hydrogen adatoms.

Sulfur adatoms strongly activate the otherwise inert Cu(111) surface towards chemoselective hydrogenation of crotonaldehyde by electronically perturbing and strongly tilting the reactant.

We performed a prospective, randomized, double-blind study to determine whether calcium and calcitriol prevents posttransplant bone loss. Thirty-eight nondiabetic and 26 diabetic patients without prior steroid exposure undergoing their first kidney or kidney-pancreas transplant were randomized to calcium, calcium plus calcitriol, or placebo. Lumbar spine (LS), femoral neck (FN), and distal radius (DR) bone mineral density scans (BMDs) were obtained at baseline, 6, and 12 months.
