Insulin-induced gene-1 (Insig-1) and its homolog Insig-2 encode closely related proteins of the endoplasmic reticulum that block proteolytic activation of sterol regulatory element binding proteins, membrane-bound transcription factors that activate synthesis of cholesterol and fatty acids in animal cells. These proteins also restrict lipogenesis in mature adipocytes and block differentiation of preadipocytes. Herein, we identified a novel 1alpha,25-dihydroxyvitamin D3 [1,25-(OH)2D3] response el

The dissolving microneedle (DMN) patch is a transdermal delivery system, containing arrays of micro-sized polymeric needles capable of encapsulating therapeutic drugs within their matrix and releasing them into the skin. However, the elastic properties of the skin prevent DMNs from complete insertion and accurate delivery of encapsulated compounds into the skin. Moreover, the adhesive materials used in patches may cause skin irritation, inflammation, and redness. Therefore, we developed a patchl

Cortical processing is dynamically modulated by different neuromodulators. Neuromodulation of the cerebral cortex is crucial for maintaining cognitive brain functions such as perception, attention and learning. However, we do not fully understand how neuromodulatory projections are organized in the cerebral cortex to exert various functions. The basal forebrain (BF) cholinergic projection and the locus coeruleus (LC) noradrenergic projection are well-known neuromodulatory projections to the cort

The emergence of new technologies has made it increasingly easy for distributed collaboration in both educational and noneducational settings. Although the effectiveness in traditional settings of the dynamics of small group work has been widely researched, there is limited research that offers evidence on how teams can work effectively in a virtual environment. The purpose of this study is to examine the relationship among team structure, trust, and conflict management style, in addition to the

Nb₃O₇(OH) nanorod-reduced graphene oxide nanocomposites with superior photocatalytic efficiency for degradation of organic dyes have been synthesized and characterized.

Atomic layer deposition (ALD) has attracted much attention, particularly for applications in nanoelectronics because of its atomic-level controllability and high-quality products. In this study, we developed a plasma-enhanced atomic layer deposition (PEALD) process to fabricate a homogeneous indium aluminum oxide (IAO) semiconductor film. Trimethylaluminum (TMA) and dimethylaluminum isopropoxide (DMAI) were used as Al precursors, which yielded different compositions. Density functional theory (D

Multisensory integration (MSI) occurs in a variety of brain areas, spanning cortical and subcortical regions. In traditional studies on sensory processing, the sensory cortices have been considered for processing sensory information in a modality-specific manner. The sensory cortices, however, send the information to other cortical and subcortical areas, including the higher association cortices and the other sensory cortices, where the multiple modality inputs converge and integrate to generate
