Article Synopsis
  • The study investigates Behavioral Activation (BA) as a potential intervention for negative symptoms of schizophrenia, which currently lack effective treatments.
  • In a trial with 70 patients, those receiving BA alongside usual treatment showed significant reductions in negative symptoms compared to those who only received usual treatment.
  • Though improvements were seen post-treatment, the benefits did not last at a six-month follow-up, highlighting the need for more research to maintain the gains from BA.

In this study, (mealworm) protein and reducing sugar were thermally reacted without (MP-RF) or with amino acids (MPA-RFs, A is then replaced with three-letter abbreviation of amino acid used in the reaction), and their Maillard reaction products (MRPs) and sensory characteristics were compared to explore the amino acids that contributed to desirable meat-related odor attributes in MP-RF. The odor characteristics perceived from MP-RF were changed based on the amino acid that was added to MP-RF and then reacted. Noticeably, a 'dried shrimp-like' attribute, which was the most intense in MP-RF, was weakened in all MPA-RFs.

Development of a reliable doping method for 2D materials is a key issue to adopt the materials in the future microelectronic circuits and to replace the silicon, keeping the Moore's law toward the sub-10 nm channel length. Especially hole doping is highly required, because most of the transition metal dichalcogenides (TMDC) among the 2D materials are electron-doped by sulfur vacancies in their atomic structures. Here, hole doping of a TMDC, tungsten disulfide (WS ) using the silicon substrate as the dopant medium is demonstrated.

Low-temperature process compatibility is a key factor in successfully constructing additional functional circuits on top of pre-existing circuitry without corrupting characteristics thereof, a technique that typically requires die-to-die (wafer-to-wafer) stacking and interconnecting. And against thermal annealing, which is mandatory and is possible only globally for activating amorphous oxide semiconductors, the selective control of electrical characteristics of the oxide thin-films for integrated circuit applications is challenging. Here, a low-temperature process that enables n-type doping of the designed region of insulating InOthin-film is demonstrated.

Behavioral activation (BA) is a beneficial and relatively cost-effective treatment option for depression. This study utilized a pragmatic randomized controlled research design to investigate whether BA, as compared with treatment as usual (TAU), led to superior treatment effects, when delivered in community mental health settings by retrained community mental health professionals. Patients with depressive disorders (n = 64) were randomly assigned to a 10-session BA (n = 31) or TAU (n = 33) group.

A new system for the easy loading and NIR light-triggered release of drugs is introduced. It consists of poly(ε-caprolactone) (PCL) hollow nanoparticles with surface openings containing a biodegradable fatty acid with phase-change ability and a biocompatible photothermal agent. These openings, which can enhance the connectivity between the interior and the exterior, enable the easy loading of drug molecules into the interior voids, and their successive sealing ensures a stable encapsulation of the drug.

In this work, we report on the layered deposition of few-layer tin disulfide (SnS) using atomic layer deposition (ALD). By varying the ALD cycles it was possible to deposit poly-crystalline SnS with small variation in layer numbers. Based on the ALD technique, we developed the process technology growing few-layer crystalline SnS film (3-6 layers) and we investigated their electrical properties by fabricating bottom-gated thin film transistors using the ALD SnS as the transport channel.

This paper introduces a new fibrous system for synergistic cancer therapy, which consists of gold nanocage (AuNC)-loaded poly(ε-caprolactone) (PCL) fibers with encapsulation of a chemotherapeutic anticancer drug in their core and loading of a phase-changeable fatty acid in their sheath. Under on⁻off switching of near-infrared (NIR) light irradiation, the excellent photothermal ability and photostability of AuNCs allows repeated, significant heating of the fibers to a temperature available to hyperthermia. Simultaneously, the NIR light-induced heat generation enables the melting out of the loaded fatty acid, leading to a rapid release of the drug molecules from the fibers.
