This review revealed that a multimodal approach was most commonly used in surface anatomy instruction. Hence, future research should explore the effectiveness of multimodal teaching strategies that adopt the three aforementioned primary elements of effective teaching in an authentic learning environment. It is pertinent to clarify the effectiveness of these teaching strategies by evaluating their impact on student learning, organizational changes, and benefits to other stakeholders.In this paper, we review the management of neonatal opioid withdrawal syndrome (NOWS) and clinical pharmacology of primary treatment agents in NOWS, including morphine, methadone, buprenorphine, clonidine, and phenobarbital. Pharmacologic treatment strategies in NOWS have been mostly empirical, and heterogeneity in dosing regimens adds to the difficulty of extrapolating study results to broader patient populations. As population pharmacokinetics (PKs) of pharmacologic agents in NOWS become more well-defined and knowledge of patient-specific factors affecting treatment outcomes continue to accumulate, PK/pharmacodynamic modeling and simulation will be powerful tools to aid the design of optimal dosing regimens at the patient level. Although there is an increasing number of clinical trials on the comparative efficacy of treatment agents in NOWS, here, we also draw attention to the importance of optimizing the dosing regimen, which can be arguably equally important at identifying the optimal treatment agent.Stroke is a leading cause of disability and mortality, with limited treatment options. After stroke injury, microglia and CNS-resident macrophages are rapidly activated and regulate neuropathological processes to steer the course of functional recovery. To accelerate this recovery, microglia can engulf dying cells and clear irreparably-damaged tissues, thereby creating a microenvironment that is more suitable for the formation of new neural circuitry. In addition, monocyte-derived macrophages cross the compromised blood-brain barrier to infiltrate the injured brain. The specific functions of myeloid lineage cells in brain injury and repair are diverse and dependent on phenotypic polarization statuses. However, it remains to be determined to what degree the CNS-invading macrophages occupy different functional niches from CNS-resident microglia. In this review, we describe the physiological characteristics and functions of microglia in the developing and adult brain. We also review (a) the activation and phenotypic polarization of microglia and macrophages after stroke, (b) molecular mechanisms that control polarization status, and (c) the contribution of microglia to brain pathology versus repair. Finally, we summarize current breakthroughs in therapeutic strategies that calibrate microglia/macrophage responses after stroke.

Myelodysplastic syndrome (MDS) is a group of heterogeneous hematological diseases characterized by ineffective hematopoiesis and dysplastic morphology. Single nucleotide polymorphism array (SNP-A)-based whole genome analysis has a much higher resolution for chromosomal alterations when compared with conventional cytogenetic tools. In the present study, we evaluated the diagnostic value and prognostic significance of SNP-A in MDS patients with normal karyotypes.

A total of 127 patients with MDS and myeloproliferative neoplasms or acute myeloid leukemia with myelodysplasia-related changes were included in our study. The advantages and disadvantages of SNP-A were compared with those of traditional metaphase cytogenetic analysis (MC). selleck chemicals llc The Kaplan-Meier analysis and COX regression analysis were used to investigate the prognostic value of SNP-A and uniparental disomy (UPD) in MDS patients with normal karyotype. Furthermore, the chromosomal abnormalities detected by SNP-A in patients with specific gene mutations were explored.

SNP-A was more sensitive toward meaningful chromosomal aberrations (58.2% vs 36.9%; P<.05) than MC. Among the patients with normal karyotype, those who were detected with new chromosomal abnormalities via SNP-A presented with inferior survival compared with those without the abnormalities (P=.003). Additionally, the presence of UPD was an independent prognostic factor in patients with normal karyotype (P=.01). TP53 and RUNX1 mutations often occurred with abnormalities in chromosomes 17p and 21q, respectively.

Compared with MC, SNP-A capable of detecting UPD can offer more diagnostic and prognostic information; TP53 and RUNX1 gene mutations are often accompanied by abnormalities in their chromosomes (17p, 22q).

CP-I is produced in the process of heme synthesis, but the relationship between plasma CP-I concentrations and heme synthesis activity is unknown. In this study, we evaluated the relationship between plasma CP-I concentration and hemoglobin level as a biomarker of heme synthesis activity. The data of 391 subjects selected from the Japanese general population were analyzed. One hundred twenty-six participants had OATP1B1*15 allele, 11 of whom were homozygous (OATP1B1*15/*15). Multiple regression analysis identified hemoglobin level as an independent variable associated with plasma CP-I concentration (p less then 0.0001). A significant positive correlation was observed between hemoglobin level and plasma CP-I concentration in participants without OATP1B1*15 allele (n = 265; rs = 0.35, p less then 0.0001) and with OATP1B1*15 allele (n = 126; rs =0.27, p = 0.0022). However, Kruskal-Wallis test showed no large difference in Kruskal-Wallis statistics between the distribution of plasma CP-I concentrations and that of ratio of plasma CP-I to hemoglobin among six OATP1B1 polymorphism groups. These findings suggest that the hemoglobin level seems to reflect biosynthesis of CP-I. However, correction by hemoglobin level is not required when using basal plasma CP-I concentration for phenotyping OATP1B activity.
