We reviewed a total of four recently published global treatment guidelines and compared each treatment recommendation of the KMAP-BP 2014 with those in other guidelines. For the initial treatment of mania, there were no significant differences across treatment guidelines. All recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or the combination of an MS with an AAP as a first-line treatment strategy for mania. However, the KMAP-BP 2014 did not prefer monotherapy with MS or AAP for dysphoric/psychotic mania. Aripiprazole, olanzapine, quetiapine, and risperidone were the first-line AAPs in nearly all of the phases of bipolar disorder across the guidelines. Most guidelines advocated newer AAPs as first-line treatment options in all phases, and lamotrigine in depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. As research evidence accumulated over time, recommendations of newer AAPs – such as asenapine, paliperidone, lurasidone, and long-acting injectable risperidone – became prominent. This comparison identifies that the treatment recommendations of the KMAP-BP 2014 are similar to those of other treatment guidelines and reflect current changes in prescription patterns for bipolar disorder based on accumulated research data. Further studies are needed to address several issues identified in our review. Keywords: bipolar disorder, pharmacotherapy, treatment algorithm, guideline comparison, KMAP-201

Tracking intracavernously injected adipose-derived stem cells to bone marrow

Intracavernous (IC) injection of stem cells (SCs) has been shown to improve erectile function in various erectile dysfunction (ED) animal models. However, the tissue distribution of the injected cells remains unknown. In this study we tracked IC injected adipose-derived stem cells (ADSCs) in various tissues. Rat paratesticular fat was processed for ADSC isolation and culture. The animals were then subject to cavernous nerve (CN) crush injury or sham operation, followed by IC injection of one million autologous or allogeneic ADSCs that were labeled with 5-ethynyl-2-deoxyuridine (EdU). Another group of rats received IC injection of EdU-labeled allogeneic penile smooth muscle cells (PSMCs). At 2 and 7 days post-injection, penises and femoral bone marrow were processed for histological analyses. Whole femoral bone marrows were also analyzed for EdU-positive cells by flow cytometry. The results show that ADSCs exited the penis within days of IC injection and migrated preferentially to bone marrow. Allogenicity did not affect ADSC's bone marrow appearance either at 2 or 7 days, while CN injury reduced the number of ADSCs in bone marrow significantly at 7 but not 2 days. The significance of these results in relation to SC therapy for ED is discussed

Magnetic Nature of Light Transmission through a 5-nm Gap

Slot antennas have been exploited as important building blocks of optical magnetism because their radiations are invoked by the magnetic fields along the axes, as vectorial Babinet principle predicts. However, optical magnetism of a few-nanometer-width slit, for which fascinating applications are found due to the colossal field enhancement but Babinet principle fails due to the nonnegligible thickness, has not been investigated. In this paper, we demonstrated that the magnetic field plays a dominant role in light transmission through a 5-nm slit on a 150-nm-thick gold film. The 5-nm slit was fabricated by atomic layer lithography, and the transmission was investigated for various incident angles by experiment and simulation at 785-nm wavelength. We found that, due to the deep subwavelength gap width, the transmission has the same incident angle dependence as the tangential magnetic field on the metal surface and this magnetic nature of a nanogap holds up to similar to 100-nm width. Our analysis establishes conditions for nanogap optical magnetism and suggests new possibilities in realizing magnetic-field-driven optical nonlinearities

Thermo-responsive nanomaterials for thermoelectric generation

In the past decades, as an emission-free technique capable of realizing direct energy conversion between heat and electricity, thermoelectric materials/applications have attracted extensive attention. The efficiency of thermoelectric modules/devices is dominated by the material dimensionless figure of merit, zT. zT of thermoelectric materials can be enhanced through both optimizing carrier transportation properties and refraining the lattice thermal conductivity. Module design can also influence the energy conversion efficiency. Proper module design, such as segmented or cascade design, can effectively utilize the potential of composing materials. Furthermore, through proper device design, the thermoelectric modules can be designed as both flexible and rigid types and applied in both niche and macro-fields

Chronotype and Psychiatric Disorders

Purpose of ReviewChronotype, reflecting interindividual differences in daily activity patterns and sleep-wake cycles, is intrinsically connected with well-being. Research indicates increased risk of many adverse mental health outcomes for evening-type individuals. Here, we provide an overview of the current evidence available on the relationship between chronotype and psychiatric disorders.Recent FindingsThe association between eveningness and depression is well established cross-sectionally, with preliminary support from longitudinal studies. The mechanisms underlying this relationship warrant further research; deficient cognitive-emotional processes have recently been implicated. Eveningness is associated with unhealthy lifestyle habits, and the propensity of evening types to addiction has been recognized. Chronotype may also be implicated in disordered eating.SummaryEveningness is associated with depression—including seasonal affective disorder (SAD)—and substance dependence, while support for a relation with anxiety disorders and psychosis is lacking. In bipolar disorder, chronotype is linked to depression but not mania. Eveningness is also related to sleep disturbances and poor lifestyle habits, which may increase risk for psychiatric disorders.FSW - Self-regulation models for health behavior and psychopathology - ou
