Marion de Jong, Stephen Mather, Theodosia Maina
Detection of useful cellular targets has strongly stimulated personalized tumor-targeted imaging and therapy approaches, also involving synthesis and evaluation of nuclear imaging probes with potential for clinical applications. Reviews of preclinical and translational studies concerning such probes, including radiolabeled antibodies, nanobodies, affibodies, peptides, small molecule inhibitors, and nanoparticles, are presented in this issue. As most tracers described in these articles have been developed for the field of cancer imaging and radionuclide therapy, the current article on preclinical studies will focus on cancer research as well...

Large multimolecular complexes of heparin with positively charged proteins such as platelet factor 4 (PF4) or protamine can initiate immune responses associated with heparin use in patients, including the most significant adverse event, heparin-induced thrombocytopenia (HIT). Current evidence suggests that platelet-activating antibodies that recognize large multi-molecular complexes (300-700kDa) of PF4 bound to heparin cause HIT [1] and in very rare cases anti-protamine-heparin antibodies can induce thrombocytopenia [2]...

A group of novel chalcone derivatives comprising hydroxamic acid or 2-aminobenzamide group as zinc binding groups (ZBG) were synthesized. The structure of the prepared compounds was fully characterized by IR, NMR and elemental microanalyses. Most of the tested compounds displayed strong to moderate HDAC inhibitory activity. Some of these compounds showed potent anti-proliferative activity against human HepG2, MCF-7 and HCT-116 cell lines. In particular, compounds 4a and 4b exhibited significant anti-proliferative activity against the three cell lines compared to SAHA as reference drug and displayed promising profile as anti-tumor candidates...

Bartonellae are blood-borne and vector-transmitted pathogens, some are zoonotic, which have been reported in several Mediterranean countries. Transmission from dogs to humans is suspected, but has not been clearly demonstrated. Our objectives were to determine the seroprevalence of Bartonella henselae, Bartonella vinsonii subsp. berkhoffii, Bartonella clarridgeiae, and Bartonella bovis (as a proxy for Candidatus Bartonella merieuxii) in stray dogs from Tunisia, identify the Bartonella species infecting the dogs and evaluate potential risk factors for canine infection...

BACKGROUND: Lymphedema is an iatrogenic complication after breast cancer treatment in which lymph fluid in the affected limb progresses to fat deposition and fibrosis that are amenable to liposuction treatment. Magnetic resonance imaging (MRI) for lymphedema can differentiate fat tissue from fluid, but estimating relative volumes remains problematic. METHODS AND RESULTS: Patients underwent routine bilateral arm MRI both before and after liposuction for advanced lymphedema...

We propose a weighted pseudolikelihood method for analyzing the association of a SNP set, example, SNPs in a gene or a genetic pathway or network, with multiple secondary phenotypes in case-control genetic association studies. To boost analysis power, we assume that the SNP-specific effects are shared across all secondary phenotypes using a scaled mean model. We estimate regression parameters using Inverse Probability Weighted (IPW) estimating equations obtained from the weighted pseudolikelihood, which accounts for case-control sampling to prevent potential ascertainment bias...

Over the last decade, engineered structures have been developed for osteochondral (OC) tissue regeneration. While the optimal structure design is yet to be determined, these scaffolds require in vitro evaluation before clinical use. However, the means by which complex scaffolds, such as OC scaffolds, can be tested are limited. Taking advantage of a mesenchymal stem cell's (MSC's) ability to respond to its surrounding we harness external cues, such as the cell's mechanical environment and delivered factors, to create an in vitro culture system for OC tissue engineering with a single cell source on a gradient yet integrated scaffold system...

High field deuterium NMR spectroscopy is used to characterize a number of molecular liquids and their mixtures in order to probe the directional part of the intermolecular interactions through the orientational ordering induced in the isotropic liquid phase by the spectrometer magnetic field. The systems studied include benzene, chloroform, hexafluorobenzene and thiophene at various concentrations and in mixtures. Dilution with the magnetically isotropic tetramethylsilane provides quantification of ordering at "infinite magnetic dilution", i...

Vaccine immunoprotection for Streptococcus pneumoniae is mediated by opsonizing antibodies targeting serotype-specific capsular polysaccharides. Quantitative antibody levels (ELISA) and antibody-mediated opsonophagcytic assays (OPA) measure vaccine-induced protection; correlation of these assays in transplantation requires investigation. This study examines the laboratory assessment of antibody titers in vaccinated renal recipients. Streptococcus pneumoniae 19A is common in immunocompromised hosts and is represented in protein-conjugate vaccines (PCV) and polysaccharide vaccines (PSV)...

The Internet has become a popular resource for patient education. The information it provides, however, is rarely peer-reviewed, and its quality may be a concern. Since the average American reads at an 8th grade level, the American Medical Association and the National Institutes of Health have recommended that health information be written at a 4th to 6th grade level. We performed a study to assess the quality and readability of online information regarding the treatment of swallowing disorders. A Google search for "swallowing treatment" was conducted...

The benefits of cochlear implantation (CI) in the elderly remain debatable in terms of sound and speech perception. Moreover, the results of CI may be affected by the intensity and pitch of spoken language. We conducted a retrospective study to evaluate surgical and hospitalization times, postoperative complications, and hearing outcomes after CI in elderly Koreans. Our study population was made up of 55 postlingually deafened adults who underwent unilateral CI. They were divided into two groups based on age; an older group consisted of 21 patients aged 65 years or older (mean 71...
