3 mGy (p<0.001). Average image noise was significantly lower for the 3rd generation DECT (SD=10.3) as compared to the 2nd generation DECT (SD=13.9) (p<0.001).

The third generation dsDECT scanners can simultaneously decrease patient radiation dose and decrease image noise as compared to second generation DECT. These reductions in radiation exposure can be particularly important in patients with urinary stone disease who often require repeated imaging to evaluate for stone development and recurrence as well as treatment assessment.

This work focuses on the development of c(RGDyK)-CUCU conjugates for the selective delivery of CUCUs to integrin-overexpressing cancer cells. The activity of the conjugates against various cancer cells was studied. They exhibited a mild cytostatic effect to six cancer cell lines and a cytotoxic effect against integrin-overexpressing MCF-7 and A549 cells. Their chemical and metabolic stability was extensively studied using LC-MS analysis. The conjugates maintained high affinity for αvβ3 integrin receptors. c(RGDyK) conjugation via a PEG linker was beneficial for CUCU-D and the resulting conjugate was approximately three-times more active than the free CUCU-D in MCF7 cells.Aim Teaching of genetics and pharmacogenetics with personal genotyping (PGT) is becoming commonplace. We aimed to perform a systematic review and meta-analysis to understand the effects of PGT on student outcomes. Methods A systematic review was performed on studies that reported the effects of PGT on student attitudes, perceptions or knowledge. CH5126766 Extracted data were summarized qualitatively and when possible, quantitatively. Results Student PGT has a positive effect on student attitude and perceptions survey responses in studies without a control group (p = 0.009) and in studies with a control group (p = 0.025). Knowledge increased after the use of PGT (p less then 0.001) in studies without a control group. Conclusion The findings here suggest that perceptions, attitudes and knowledge increase with PGT in the classroom.Aim Explore the possible association between clinical factors and genetic variants of the dopamine pathways and negative symptoms. Materials & methods Negative symptoms were assessed in 206 patients with schizophrenia using the Arabic version of the self-evaluation of negative symptoms scale and the Positive and Negative Syndrome Scale. Genotyping for COMT, DRD2, MTHFR and OPRM1 genes was performed. Results Multivariable analysis showed that higher self-evaluation of negative symptoms scale scores were significantly associated with higher age, higher chlorpromazine-equivalent daily dose for typical antipsychotics and in married patients. Higher negative Positive and Negative Syndrome Scale scores were significantly associated with women and having the CT genotype for MTHFR c.677C>T (β = 4.25; p = 0.008) compared with CC patients. Conclusion Understanding both clinical/genetic factors could help improve the treatment of patients.Although statins (3-hydroxy-3-methylglutaryl-CoA reductase inhibitors) have proven effective in reducing plasma low-density lipoprotein levels and risk of cardiovascular disease, their lipid lowering efficacy is highly variable among individuals. Furthermore, statin treatment carries a small but significant risk of adverse effects, most notably myopathy and new onset diabetes. Hence, identification of biomarkers for predicting patients who would most likely benefit from statin treatment without incurring increased risk of adverse effects can have a significant public health impact. In this review, we discuss the rationale for the use of subject-derived lymphoblastoid cell lines in studies of statin pharmacogenomics and describe a variety of approaches we have employed to identify novel genetic markers associated with interindividual variation in statin response.Aim Assess the suitability of standard parametric, piecewise and mixture cure models (MCMs) for modeling long-term survival of acute myeloid leukemia patients achieving remission following treatment with gemtuzumab ozogamicin (GO) + standard chemotherapy (SC) or SC alone. MCMs can model survival data comprising of statistically cured (patients in long-term remission) and uncured patients. Materials & methods Models were fit to patient-level data corresponding to individual treatment arms. Results Visual inspection showed that MCMs fit the clinical data best. Survival modeling with MCMs showed that treatment with GO + SC versus SC alone results in higher statistical cure rates for event-free survival (rates 26-35% vs 21-23%) and overall survival (rates 48-52% vs 38-44%). Conclusion MCMs are well suited to modeling long-term survival in acute myeloid leukemia patients. Clinical trial registration NCT00927498 (ClinicalTrials.gov).The morbidity and mortality of myocardial ischemia-reperfusion injury (MIRI) have increased in modern society. Noncoding RNAs (ncRNAs), including lncRNAs, circRNAs, piRNAs and miRNAs, have been reported in a variety of studies to be involved in pathological initiation and developments of MIRI. Hence this review focuses on the current research regarding these ncRNAs in MIRI. We comprehensively introduce the important features of lncRNAs, circRNAs, piRNA and miRNAs and then summarize the published studies of ncRNAs in MIRI. A clarification of lncRNA-miRNA-mRNA, lncRNA-transcription factor-mRNA and circRNA-miRNA-mRNA axes in MIRI follows, to further elucidate the crucial roles of ncRNAs in MIRI. Bioinformatics analysis has revealed the biological correlation of mRNAs with MIRI. We provide a comprehensive perspective for the roles of these ncRNAs and their related networks in MIRI, providing a theoretical basis for preclinical and clinical studies on ncRNA-based gene therapy for MIRI treatment.
