C-X-C-motif chemokine receptor 4 (CXCR4) is a key factor for tumor growth and metastasis in several types of human cancer. We have recently reported promising first-in-man experience with CXCR4-directed endoradiotherapy (ERT) in multiple myeloma (MM). Eight heavily pretreated MM patients underwent a total of 10 ERT cycles (7 patients with 1 cycle and a single patient with 3 cycles). ERT was administered in combination with chemotherapy and autologous stem cell support. End points were occurrence and timing of adverse events, progression-free and overall survival...

BACKGROUND: By affecting the internal timing mechanisms of the brain, light regulates human physiology and behavior, perhaps most notably the sleep-wake cycle. Humans spend over 90% of their waking hours indoors, yet light in the built environment is not designed to affect circadian rhythms. OBJECTIVE: Using a device calibrated to measure light that is effective for the circadian system (circadian-effective light), collect personal light exposures in office workers and relate them to their sleep and mood...

Shoulder dislocations are common shoulder injuries associated with athletic activity in contact sports, such as football, rugby, wrestling, and hockey. Identifying genetic loci associated with shoulder dislocation could shed light on underlying mechanisms for injury and identify predictive genetic markers. To identify DNA polymorphisms associated with shoulder dislocation, a genome-wide association screen was performed using publically available data from the Research Program in Genes, Environment and Health including 662 cases of shoulder dislocation and 82 602 controls from the European ancestry group...

Geobacillus stearothermophilus spores on stainless steel discs are routinely used as Biological Indicators (BIs) for the validation of hydrogen peroxide bio-decontamination processes. Given ongoing concerns about the reliability and response time of BIs, we explored the potential for an enzyme-based approach decontamination process evaluation. Thermostable adenylate kinase (tAK) enzyme was coated onto a solid support and exposed to hydrogen peroxide vapour, in parallel with standard commercial 6-log BIs, during a series of vapour-phase hydrogen peroxide (VPHP) cycles in a flexible film isolator...

Standard treatment for GBM is radiation (RT) and temozolomide (TMZ). Arsenic trioxide (ATO) is synergistic with RT based on several mechanisms of action previously identified, however not tested herein. The MTD of ATO, RT and TMZ was determined in a Phase I trial. We now present the combined Phase I/II data. Patients with newly diagnosed malignant gliomas were eligible for treatment. Patients were treated with RT (60 GY), TMZ (75 mg/m(2) daily × 42 days) and ATO 0.20 mg/kg daily in week 1 then twice a week ×5 weeks, after completing RT they were treated with TMZ 5/28 for up to 12 months...

STUDY QUESTION: Is supraphysiologic estradiol (E2) an independent predictor of low birth weight (LBW) in singletons born after fresh IVF-embryo transfer (ET) cycles? SUMMARY ANSWER: Our results suggest that E2 > 2500 pg/ml is an independent predictor for LBW in full-term singletons born to normal responder patients undergoing fresh IVF-ET cycles. WHAT IS KNOWN ALREADY: The pathogenesis of LBW in IVF singletons remains unknown. However, recent studies have suggested that the hyperestrogenic milieu generated during ovarian stimulation may create a sub-optimal peri-implantation environment, leading to placental dysfunction, and therefore, LBW...

High-grade glioma (HGG) is an incurable brain cancer. The transcriptomes of cells within HGG tumors are highly heterogeneous. This renders the tumors unresponsive or able to adapt to therapeutics targeted at single pathways, thereby causing treatment failure. To overcome this, we focused on cyclin-dependent kinase 7 (CDK7), a ubiquitously expressed molecule involved in two major drivers of HGG pathogenesis: cell cycle progression and RNA polymerase-II-based transcription. We tested the activity of THZ1, an irreversible CDK7 inhibitor, on patient-derived primary HGG cell lines and ex vivo HGG patient tissue slices, using proliferation assays, microarray analysis, high-resolution respirometry, cell cycle analysis and in vivo tumor orthografts...

BACKGROUND & AIMS: Exercise is an important component of obesity associated disorders and has been shown to reduce markers of non-alcoholic fatty liver disease (NAFLD). However, little is known about how these effects are influenced by alcohol intake. We performed a randomized controlled trial to investigate the effects of exercise on hepatic triglyceride content (HTGC) and metabolism in overweight or obese patients who consume alcohol. METHODS: We performed a prospective study of 27 patients (mean age 54±11years, body mass index [BMI], 31±4kg/m2) with >5% HTGC in the United Kingdom, consuming alcohol (mean 221±75 g/week)...

The olivary pretectal nucleus (OPT) is a midbrain structure that receives reciprocal bilateral retinal projections, is involved in the pupillary light reflex, and connects reciprocally with the intergeniculate leaflet (IGL), a retinorecipient brain region that mediates behavioral responses to light pulses (i.e., masking) in diurnal Nile grass rats. Here, we lesioned the OPT and evaluated behavioral responses in grass rats to various lighting conditions, as well as their anxiety-like responses to light exposure...
