Function of orexin-1 receptor signaling in the olfactory tubercle in odor-guided attraction and aversion.

While olfactory behaviors are influenced by neuromodulatory signals, the underlying mechanism remains unknown. The olfactory tubercle (OT), a component of the olfactory cortex and ventral striatum, consists of anteromedial (am) and lateral (l) domains regulating odor-guided attractive and aversive behaviors, respectively, in which the amOT highly expresses various receptors for feeding-regulated neuromodulators. Here we show functions of appetite-stimulating orexin-1 receptor (OxR1) signaling in the amOT.

Virus-induced host cell metabolic alteration.

Viruses change the host cell metabolism to produce infectious particles and create optimal conditions for replication and reproduction. Numerous host cell pathways have been modified to ensure available biomolecules and sufficient energy. Metabolomics studies conducted over the past decade have revealed that eukaryotic viruses alter the metabolism of their host cells on a large scale.

CeO nanorods supported CuO-RuO bimetallic catalysts for low temperature CO oxidation.

Bimetallic catalysts often outperform monometallic catalysts due to changeable structural orientation, synergistic effects, and integration of two different metal or metal oxide properties. Here, a series of CeO nanorods (NR) supported bimetallic CuO and RuO catalysts (Cu: Ru ratios of 9:1, 7:3, and 5:5) were prepared using a wet impregnation method. In situ DRIFTS, H temperature programmed reduction (H-TPR), CO temperature programmed desorption (CO-TPD), and other characterization techniques were used to investigate the effect of the Cu:Ru ratio on the activity of low-temperature CO oxidation.

Role of Nuclear Morphometry in the Cytologic Evaluation of Benign and Malignant Thyroid Lesions.

Thyroid lesions are very common problem in Bangladesh. To categorize the type of lesion, FNAC is a reliable, minimally invasive and cost-effective diagnostic modality. In routine cytology, precise categorization into benign and malignant is highly subjective.

Low-Temperature Plasma-Assisted Catalytic Dry Reforming of Methane over CeO Nanorod-Supported NiO Catalysts in a Dielectric Barrier Discharge Reactor.

Nonthermal plasma (NTP)-assisted catalytic dry reforming of methane (DRM) is considered a powerful single-stage reaction mechanism because of its ability to activate normally stable CO and CH at a low temperature under ambient conditions. The thermodynamic barrier of DRM requires a high operating temperature (>700 °C), which can be reduced by nonequilibrium plasma. Herein, we present a method for the wet-impregnation synthesis of CeO nanorod (NR)-supported 5 and 15 wt % NiO catalysts for efficient NTP-promoted DRM with an applied power in the range of 24.
