Circulating microRNA 134 sheds light on the diagnosis of major depressive disorder.

Major depressive disorder (MDD) is a prevalent and debilitating psychiatric mood disorder that lacks objective laboratory-based tests to support its diagnosis. A class of microRNAs (miRNAs) has been found to be centrally involved in regulating many molecular processes fundamental to central nervous system function. Among these miRNAs, miRNA-134 (miR-134) has been reported to be related to neurogenesis and synaptic plasticity.

Innovative methodology for recovering titanium and chromium from a raw ilmenite concentrate by magnetic separation after modifying magnetic properties.

Raw ilmenite concentrate containing Cr can be either as a resource or as one kind of the most hazardous solid waste. In order to recover titanium and chromium from the raw concentrate which was separated from the Promenade deposit, Gaza province, Mozambique, an innovative technology using modification of magnetic property followed by magnetic separation was proposed. Magnetic property, phase and surface morphology of the sample before and after oxidizing roasting were firstly characterized by magnetism, chemistry, XRD and MLA analyses to interpret the mechanism of oxidizing roasting of the ilmenite.

[Three-dimensional imaging for quantitative evaluation of facial profile of edentulous patients before and after complete dentures restoration].

Objective: To collect and analyze the Three-dimensional (3D) facial profile variation of edentulous patients restored by complete denture.

Methods: The 3D facial images of 20 Atwood Class II edentulous patients were taken by DSC-2 3D facial imaging system before and after restoration of complete denture. Then, the two 3D facial images of each patient before and after restoration were registered in the same coordinate system by partial structure overlap.

Chemical composition, antimicrobial and antioxidant activities of essential oil from Ampelopsis megalophylla.

Chemical composition, antimicrobial and antioxidant activities of the essential oil of Ampelopsis megalophylla were evaluated in this research. GC-MS analysis of the essential oil revealed 42 compounds, representing 88.54% of the oil.

μ-11,23-Dibromo-3,7,15,19-tetra-aza-tri-cyclo-[19.3.1.1]hexa-cosa-1(25),2,7,9,11,13(26),14,19,21,23-deca-ene-25,26-diolato-κN,N,O,O':κO,O',N,N]bis[perchloratocopper(II).

The title complex, [Cu(2)(C(22)H(20)Br(2)N(4)O(2))(ClO(4))(2)], was prepared by the condensation of 2,6-diformyl-4-bromo-phenol with 1,3-diamino-propane in the presence of copper(II) ions. The macrocyclic ligand shows an approximately planar structure except for the two propene groups in the macrocycle. The coordination polyhedron of each Cu atom can be described as distorted square pyramidal.

[The effect of simulate intraoral sandblasting on the band strength between enamel and composite resin].

Objective: To study whether the bond strength between enamel and composite resin could be enhanced by intraoral sand abrasive.

Methods: Ten human maxillary first incisior teeth were divided into 2 groups The experimental group was sandblasted with 30 microm Al2O3 (CoJet-Sand, pressure 300 kPa) from a distance of 5 mm for 5 seconds, and the control group were not sandblasted. The Herculite composite resin composite cylinders were bonded with Coltene system.
