Effect of sulfuric acid hydrolysis on the structure and Pickering emulsifying capacity of acorn starch.

The acid-hydrolyzed acorn starch samples (HAS-1, HAS-2, HAS-3, and HAS-4) were prepared from natural acorn starch (NAS) at sulfuric acid concentrations of 1, 2, 3, and 4 mol/L for 2 d. The particle characteristics and structures of HAS were investigated, and Pickering high internal phase emulsions (HIPEs) based on HAS were constructed and characterized. The results showed that with an increase in sulfuric acid concentration, the size, yield, amylose content, molecular weight, and amylopectin chain length of HAS gradually decreased.

The physicochemical properties and Pickering emulsifying capacity of acorn starch.

In this work, the granule characteristics, functional properties, in-vitro digestibility, antioxidant capacity, and phenolic composition of acorn starch were investigated and compared to those of potato starch and corn starch, and its Pickering emulsifying ability was also evaluated. The results showed that the acorn starch granules were spherical and oval in shape, with a smaller particle size, and the amylose content and crystallinity degree were similar to those of corn starch. However, the acorn starch was difficult to swell, with poor aqueous solubility, though it had a strong gel strength and setback viscosity.

Fabrication and characterization of Pickering high internal phase emulsions stabilized by Tartary buckwheat bran flour.

The abilities of Tartary buckwheat whole flour (TBWF), Tartary buckwheat core flour (TBCF), and Tartary buckwheat bran flour (TBBF) to directly construct Pickering high internal phase emulsions (HIPEs) were compared. The results indicated that these flours had a similar appearance and size distribution, but TBBF was rich in proteins, lipids, and rutin. As a result, its hydrophobicity and ability to reduce interfacial tension were superior to TBWF and TBCF.

Polymorph control by designed ultrasound application strategy: The role of molecular self-assembly.

Molecular self-assembly plays a vital role in the nucleation process and sometimes determines the nucleation outcomes. In this study, ultrasound technology was applied to control polymorph nucleation. For the first time, different ultrasonic application methods based on the nucleation mechanisms have been proposed.

Synthesis of amphoteric fluorescent copolymers: materials exhibiting multicolor photophysical properties.

Six emissive amphoteric copolymers were prepared and characterized (H NMR, DSC, steady-state UV-vis, and emission spectroscopy) in the paper. A system of multi-color emitters, composed of P1 (green and yellow), P2 (green), P3 (red), P4 (blue), P5 (yellow) and P6 (green and yellow), were presented. P5 showed multicolor fluorescence that belonged to the color-specially emissive system at different excitation wavelengths, and P6 exhibited color-correlated emission by efficient energy transfer.

Expression of protein kinase A and the kappa opioid receptor in selected brain regions and conditioned place aversion in morphine-dependent rats.

This study examined adaptive changes in protein kinase A (PKA) and kappa opioid receptor (KOR) in selected addiction-related brain regions before and after conditioned place aversion (CPA). Seventy-two male SD rats were randomly assigned to an experimental group (morphine + naloxone, "MN") and 2 control groups: MS (morphine + saline) and SN (saline + naloxone). MN rats were intraperitoneally injected with morphine twice per day for 6.

Association of PDE4B Polymorphisms with Susceptibility to Schizophrenia: A Meta-Analysis of Case-Control Studies.

Background: The PDE4B single nucleotide polymorphisms (SNPs) have been reported to be associated with schizophrenia risk. However, current findings are ambiguous or even conflicting. To better facilitate the understanding the genetic role played by PDE4B in susceptibility to schizophrenia, we collected currently available data and conducted this meta-analysis.

Altered functional interaction hub between affective network and cognitive control network in patients with major depressive disorder.

Emotional and cognitive dysregulation in major depressive disorder (MDD) have been consistently considered to be attributed to structural and functional abnormalities in affective network (AN) and cognitive control network (CCN). This study was to investigate the functional connectivity (FC) patterns and altered functional interactions between both networks in MDD. We investigated resting-state functional connectivity magnetic resonance imaging in the AN and the CCN in 25 MDD and 35 healthy controls (HC).

Preparation and characterization of foxtail millet bran oil using subcritical propane and supercritical carbon dioxide extraction.

The foxtail millet (Setaria italica Beauv) bran oil was extracted with traditional solvent extraction (SE), supercritical carbon dioxide extraction (SCE) and subcritical propane extraction (SPE) and analyzed the yield, physicochemical property, fatty acid profile, tocopherol composition, oil oxidative stability in this study. The yields of foxtail millet bran oil by SE, SCE and SPE were 17.14 %, 19.

[Changes of protein kinase A expressions in central amygdaloid nuclei during the process of chronic morphine-induced conditioned place aversion in rats].

Objective: To explore neurobiological mechanisms of the withdrawal-induced aversion. The changes of protein kinase A were measured in central amygdaloid nucleic (CeA) of conditioned place aversion (CPA) model rats.

Methods: (1) All 72 male SD rats were divided into three groups, model group (MN group), and control group (MS group and SN group).

5-HT2A receptor gene polymorphism and negative symptoms in first episode (drug-naive) Chinese Han nationality individuals with schizophrenia.

Objective: To investigate whether the 5-hydroxytryptamine 2A receptor (5-HT2A) gene T102C polymorphism is associated with the severity symptoms and negative symptoms in the first episode Chinese Han nationality patients with schizophrenia.

Methods: Altogether 201 first episode Chinese Han nationality patients with schizophrenia were enrolled in this study. Genotyping of 5-HT2A gene T102C polymorphism was performed by PCR-RFLP technique.

Simultaneous determination of geniposide and its metabolites genipin and genipinine in culture of Aspergillus niger by HPLC.

When cultivated with Aspergillus niger, geniposide, an important drug, is transformed into genipin and genipinine. A simple and rapid HPLC method for simultaneous determination of geniposide and its two metabolites in broth of A. niger is described.

[Association study of the polymorphisms of monoamine oxidase A genes with schizophrenia].

Objective: To investigate the relationship between monoamine oxidase A (MAOA) gene polymorphisms and schizophrenia in a Chinese Han population.

Methods: Two hundred and twelve schizophrenic patients and 168 healthy controls were recruited according to CCMD-3. The polymorphisms of MAOA gene were determined with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique.
