Conjugated lactam-steroid alkylators (LSA), have been shown to exhibit superior activity at controlling cancer models and overlap drug resistance to conventional chemotherapy. Hybrid LSAs combine two active compounds in a single molecule and incorporate modified steroids bearing lactam moiety in one or more steroid rings functioning as vectors for cytotoxic agents. We first describe a novel class of LSAs that generate excellent anticancer activity against UWB1.289 and UWB1.289+BRCA1 human ovarian cancer cell lines...

BACKGROUND: Implantable cardioverter defibrillator (ICD) therapy is first-line treatment for the primary and secondary prevention of sudden cardiac death. Despite the unequivocal medical benefits, living with an ICD may affect patients' psychological functioning and general well-being. We examined the trajectories of symptoms of posttraumatic stress disorder (PTSD) and anxiety in patients with an ICD and the vulnerability factors associated with an increased risk of symptoms of PTSD and anxiety...

Follicular lymphoma is a lymphoid malignancy commonly showing slow progression which makes the treatment of the disease challenging. Rituximab monotherapy and rituximab added to standard chemotherapy has been proven to increase survival among patients with advanced stage of the disease. However, the benefit of a rituximab maintenance therapy after induction was still unclear at the time of the initiation of this study. HUSOM was a phase III open-label, single-arm, multi-centre study aimed to assess the efficacy and the safety of the 12 cycles of rituximab (375 mg/m(2) every 8 weeks) maintenance therapy in patients had already presented partial or complete response to R-CVP or R-CHOP...

PURPOSE: Location of the primary tumor is prognostic and predictive of efficacy with VEGF-inhibitors (I) versus EGFR-I given first-line to metastatic colorectal cancer (mCRC) patients. However, little is known regarding the effect of location on prognosis and prediction in refractory mCRC. We assessed the efficacy of VEGF-I and EGFR-I in regards to location of the primary tumor in patients with refractory mCRC enrolled in early phase studies. METHODS: A historical cohort analysis of mCRC patients, including 44 phase I trials our institution, from March 2004 to September 2012...

One hundred and fifty-four preweaning calves were followed between May and October 2015. Calves were fitted with continuous monitoring temperature probes (TempVerified FeverTag), programmed so a flashing light emitting diode (LED) light was triggered following six hours of a sustained ear canal temperature of ≥39.7°C. A total of 83 calves (61.9 per cent) developed undifferentiated fever, with a presumptive diagnosis of pneumonia through exclusion of other calf diseases. Once fever was detected, calves were randomly allocated to treatment groups...

The R7 regulator of G protein signaling family (R7-RGS) critically regulates nervous system development and function. Mice lacking all R7-RGS subtypes exhibit diverse neurological phenotypes, and humans bearing mutations in the retinal R7-RGS isoform RGS9-1 have vision deficits. Although each R7-RGS subtype forms heterotrimeric complexes with Gβ5 and R7-RGS binding protein (R7BP) that regulate G protein-coupled receptor signaling by accelerating deactivation of Gi/o α-subunits, several neurological phenotypes of R7-RGS knockout mice are not readily explained by dysregulated Gi/o signaling...

Multiple studies have documented that Enhancer of zeste homolog 2 (EZH2) could play a role in inflammation and a wide range of malignancies; however, the underlying mechanisms remain largely unaddressed. Microglial activation is a key process in the production and release of numerous pro-inflammatory mediators that play important roles in inflammation and neurodegeneration in the central nervous system (CNS). Therefore, our aim was to investigate whether inhibition of EZH2 with the selective small molecule inhibitor EPZ-6438 protects against neonatal microglial activation...

BACKGROUND: Crowned dens syndrome (CDS) is a radioclinical entity defined by calcium deposition on the transverse ligament of atlas (TLA). In this study, the novel semi-quantitative diagnostic criteria for CDS to evaluate the degree of calcification on TLA by cervical CT are proposed. METHOD: From January 2010 to September 2014, 35 patients who were diagnosed with CDS by cervical CT were adopted as subjects in this study. Based on novel criteria, calcium deposition on TLA was classified into "Stage" and "Grade", to make a score, which was evaluated semi-quantitatively...

BACKGROUND: The function of the prion protein, involved in the so-called prion diseases, remains a subject of intense debate and the possibility that it works as a pleiotropic protein through the interaction with multiple membrane proteins is somehow supported by recent reports. Therefore, the use of proteomic and bioinformatics combined to uncover cellular processes occurring together with changes in the expression of the prion protein may provide further insight into the putative pleiotropic role of the prion protein...

The mainstay for the current treatment of severe aortic stenosis includes surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). In patients with high operative risk TAVI is established as first line therapy. New data on intermediate and low risk groups demonstrate at least non-inferiority of TAVI against SAVR, and in the near future a consistently rising number of transcatheter procedures may be anticipated. The purpose of this review is to outline the decision making process, hence to illustrate the diagnostic algorithm and to provide criteria for a differentiated approach against the background of recent data...

BACKGROUND AND OBJECTIVE: 5-Fluorouracil (5-FU) is a first-line chemotherapeutic drug in colorectal cancer. However, intravenous administration of 5-FU at the dose of 7-12mg/kg exhibits curbs like short half-life (20min) and toxic side-effects on bone marrow cells. Therefore, in present investigation, 5-FU was conjugated to poly (ethylene glycol) anchored recombinant human serum albumin nanoparticles (5-FU-rHSA-PEG-NPs) to improve the pharmacokinetic and therapeutic profiles. METHODS AND RESULTS: The mean particle size of 5-FU-rHSA-NPs was measured to be 44...

Fluoropyrimidines are the first-line treatment for colorectal cancer, but their efficacy is highly variable between patients. We queried whether gut microbes, a known source of inter-individual variability, impacted drug efficacy. Combining two tractable genetic models, the bacterium E. coli and the nematode C. elegans, we performed three-way high-throughput screens that unraveled the complexity underlying host-microbe-drug interactions. We report that microbes can bolster or suppress the effects of fluoropyrimidines through metabolic drug interconversion involving bacterial vitamin B6, B9, and ribonucleotide metabolism...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction presenting as a prothrombotic disorder related to antibody-mediated platelet activation. It is a paradoxical immune reaction resulting in thrombin generation in vivo, which leads to a hypercoagulable state and the potential to initiate venous or arterial thrombosis. A number of factors are thought to influence the incidence of HIT including the type and preparation of heparin (unfractionated heparin (UFH) or low molecular weight heparin (LMWH)) and the heparin-exposed patient population, with the postoperative patient population at higher risk...

Secretory IgA (sIgA) and its transcytosis receptor, polymeric immunoglobulin receptor (pIgR), along with mucus, form the first lines of intestinal defense. Threonine (Thr) is a major component of intestinal mucins and IgA, which are highly secreted under lipopolysaccharide (LPS) induced inflammation. In the current study, the effect of Thr on the secretory immune system was determined in an ex vivo chicken ileal explant model. Results showed that a 2-hour Thr-deprivation of culture medium induced a compensatory increase in the mRNA expression of interleukin-8 (IL-8), mucin 2 ( ), and IgA during LPS challenge, and this increase was suppressed with Thr addition to the media ( P  ≤ 0...
