A two-step metal assisted chemical etching technique is used to systematically vary the sidewall roughness of Si nanowires in vertically aligned arrays. The thermal conductivities nanowire arrays are studied using time domain thermoreflectance and compared their high-resolution transmission electron microscopy determined roughness. conductivity with small close a theoretical prediction based on an upper limit mean-free-paths phonons given by diameter. large found be significantly below this...
Abstract Background Mitochondrial transplantation (MTx) is an emerging but poorly understood technology with the potential to mitigate severe ischemia–reperfusion injuries after cardiac arrest (CA). To address critical gaps in current knowledge, we test hypothesis that MTx can improve outcomes CA resuscitation. Methods This study consists of both vitro and vivo studies. We initially examined migration exogenous mitochondria into primary neural cell culture vitro. Exogenous extracted from...
Abstract The oxygen evolution reaction, which involves high overpotential and slow charge-transport kinetics, plays a critical role in determining the efficiency of solar-driven water splitting. chiral-induced spin selectivity phenomenon has been utilized to reduce by-product production hinder charge recombination. To fully exploit polarization effect, we herein propose dual spin-controlled perovskite photoelectrode. three-dimensional (3D) serves as light absorber while two-dimensional (2D)...
To investigate the real-world efficacy and toxicity of paclitaxel-cisplatin-bevacizumab identify prognostic factors for in platinum-naïve primary stage IVB cervical cancer. We retrospectively reviewed patients with cancer who received as first-line treatment between July 2015 December 2021 at Asan Medical Center, Korea. Patient data including clinicopathologic characteristics, imaging, administration, recurrence, survival were collected. Overall, 61 included this study. The median age was 56...
Role of iron in hair loss is not clear yet.The purpose this study was to evaluate the relationship between and loss.Retrospective chart review conducted on patients with female pattern (FPHL) male (MPHL).All underwent screening including serum ferritin, iron, total binding capacity (TIBC), CBC, ESR thyroid function test.For normal healthy controls, age-sex matched subjects who had visited hospital for a check-up no serious disease were selected.A 210 FPHL (n = 113) MPHL 97) controls...
Mitochondria can depolarize and trigger cell death through the opening of mitochondrial permeability transition pore (MPTP). We recently showed that an increase in long chain n3 polyunsaturated fatty acids (PUFA) docosahexaenoic acid (DHA; 22:6n3) depletion n6 PUFA arachidonic (ARA; 20:4n6) membranes is associated with a greater Ca2+ load required to induce MPTP opening. Here we manipulated phospholipid composition by supplementing diet DHA, ARA or combined DHA+ARA rats for 10 weeks. There...
Low-loss optical isolators and circulators are critical nonreciprocal components for signal routing protection, but their chip-scale integration is not yet practical using standard photonics foundry processes. The significant challenges that confront of magneto-optic systems on chip have made imperative the exploration magnet free alternatives. However, none these approaches demonstrated linear isolation with ideal characteristics over a microscale footprint - simultaneously incorporating...
The human brain possesses three predominate phospholipids, phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylserine (PS), which account for approximately 35–40%, 20% of the brain’s respectively. Mitochondrial membranes are relatively diverse, containing aforementioned PC, PE, PS, as well phosphatidylinositol (PI) phosphatidic acid (PA); however, cardiolipin (CL) phosphatidylglycerol (PG) exclusively present in mitochondrial membranes. These phospholipid interactions...
Cardiolipin (CL) is a phospholipid predominantly found in the mitochondrial inner membrane and associated structurally with individual complexes of electron transport chain (ETC). Because ETC major reactive oxygen species (ROS)-generating site, proximity to bisallylic methylenes PUFA chains CL make it likely target ROS membrane. Oxidized cellular products, uniquely derived from ROS-induced autoxidation, could serve as biomarkers for presence help understanding mechanism oxidative stress....
MoO x -supported Mo enhances peroxide adsorption strength and electron transport, enhancing H 2 O production efficiency in Cu 3 BiS -based photocathode. Finally, unbiased PEC–PEC system coupled with perovskite photoanode shows efficient production.
The urgent need to alleviate global warming and limit the consumption of fossil fuels has prompted development rechargeable Zn–air batteries (ZABs) considering their superior energy density, safety, cost-effectiveness. However, sluggish reaction kinetics oxygen evolution (OER) unfavorable properties conventional OER catalysts (including low electrical conductivity use active site-blocking binders) hinder practically viable ZABs. Herein, we report a distinct approach for directly synthesizing...
This paper introduces a new kind of mosaic, called Jigsaw Image Mosaic (JIM), where image tiles arbitrary shape are used to compose the final picture. The generation is solution following problem: given an arbitrarily-shaped container and set tiles, fill as compactly possible with similar color taken from input while optionally deforming them slightly achieve more visually-pleasing effect. We approach problem by defining mosaic tile configuration that minimizes mosaicing energy function....
