Surface-enhanced Raman spectroscopy as a powerful method for the analysis of Chinese herbal medicines.

Chinese herbal medicines (CHMs) derived from nature have received increasing attention and become more popular. Due to their diverse production processes, complex ingredients, and different storage conditions, it is highly desirable to develop simple, rapid, efficient and trace detection methods to ensure the drug quality. Surface-enhanced Raman spectroscopy has the advantages of being time-saving, non-destructive, usable in aqueous environments, and highly compatible with various biomolecular samples, providing a promising analytical method for CHM.

Formation of Robust Polydimethylsiloxane Coatings on the Flexspline Material and Mechanism of the Tribological Property Improvement.

Flexspline frictional degradation causes failure of harmonic drives. This study focused on the improvement of the flexspline tribological properties. Flexspline material 40Cr was modified with a robust polydimethylsiloxane (PDMS) coating.

Serum Exosome-Derived miR-139-5p as a Potential Biomarker for Major Depressive Disorder.

Background: MicroRNAs (miRs) have been suggested to be biomarkers to inform the diagnosis of major depressive disorder (MDD). We have previously shown that exosome-derived miR-139-5p had potential in differentiating between patients with MDD and healthy control (HC) subjects.

Materials And Methods: To validate the potential of exosome-derived miR-139-5p as a biomarker for MDD, here we recruited 30 patients with MDD and 30 HC subjects, and used TaqMan probes to detect serum exosomal miR-139-5p levels.

Hydrazine 5,5'-bitetrazole-1,1'-diolate: a promising high density energetic salt with good properties.

The development of new environmentally friendly energetic compounds with reasonable detonation performance and safety is a long-term target in energetic materials research. A new energetic eco-friendly salt of hydrazine 5,5'-bitetrazole-1,1'-diolate (HA·BTO) is developed based on the reaction of 1H,1'H-5,5'-bitetrazole-1,1'-diolate (BTO) with hydrazine hydrochloride (HA·HCl), and fully characterized. The monocrystal of the title salt is obtained and the structure is determined by powder X-ray diffraction and single crystal X-ray diffraction.

Multiple irritation fibromas after dorsum linguae biopsy.

Irritation fibroma is one of the most frequent occurrences in benign soft tissue growth of the oral cavity. Chronic irritation and trauma are often identified as the causative factors. Recently, we experienced an unusual case of multiple irritation fibromas that occurred in the suture points after dorsum linguae biopsy.

Specific lipase-responsive polymer-coated gadolinium nanoparticles for MR imaging of early acute pancreatitis.

Currently, available methods for diagnosis of acute pancreatitis (AP) are mainly dependent on serum enzyme analysis and imaging techniques that are too low in sensitivity and specificity to accurately and promptly diagnose AP. The lack of early diagnostic tools highlights the need to search for a highly effective and specific diagnostic method. In this study, we synthesized a conditionally activated, gadolinium-containing, nanoparticle-based MRI nanoprobe as a diagnostic tool for the early identification of AP.

[Development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants].

The study on the development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants, i. e., cucumber, hairy gourd, bitter cucumber, and sponge gourd, showed that the one generation development duration of B.

[Effect of early nutritional support on plasma superoxide dismutase, malondialdehyde and nitric oxide in rats with burns in a hot and humid environment].

Objective: To observe the changes of plasma superoxide dismutase (SOD), malondialdehyde (MDA) and nitric oxide (NO) in rats with combined stress of burn injury and hot and humid environment.

Methods: The rats with superficial second-degree scald were subjected to intragastric administration of double-distilled water for one week (control group) or treated with ascorbic acid and L-arginine mixed with a-Tocopherol for one week (treatment group). All the rats were exposed to the same hot and humid environment of Td 37+/-0.
