Four New Species of (Thelephorales, Basidiomycota) from Subtropical Forests in Southwestern China.

Species of the basidiomycetous genus are widely distributed throughout temperate forests. Numerous studies on the taxonomy and phylogeny of have been conducted from the temperate zone in the Northern hemisphere, but few have been from subtropical forests. In this study, four new species, , , and from the subtropical mixed forests of Southwestern China, are described and illustrated based on morphological characteristics and phylogenetic analyses of the internal transcribed spacer regions (ITS) and the large subunit of the nuclear ribosomal RNA gene (LSU).

Preparation of a Tetra-Imidazolium Salt and Sensing for -Dinitrobenzene.

A macrocyclic tetra-imidazolium salt () based on quinoxaline was prepared and characterized. The recognition of to nitro compounds was investigated by fluorescence spectroscopy, H NMR titrations, MS, IR spectroscopy, and UV/vis spectroscopy. The results displayed that was able to effectively differentiate -dinitrobenzene from other nitro compounds via the fluorescence method.

An ion mobility-enabled and high-efficiency hybrid scan approach in combination with ultra-high performance liquid chromatography enabling the comprehensive characterization of the multicomponents from Carthamus tinctorius.

Liquid chromatography/mass spectrometry (LC/MS) is extensively applied for the untargeted/targeted analyses of the herbal components, utilizing data-dependent acquisition (DDA) or data-independent acquisition (DIA) to record the fragmentation information useful for the structural elucidation. A new trend recently has emerged by integrating DDA and DIA to render the hybrid scan, which, unfortunately, has rarely been reported. Herein, by using the Vion™ ion-mobility quadrupole time-of-flight mass spectrometer, a hybrid scan strategy (HDMS-HDDDA) was presented and validated by the untargeted characterization of the multicomponents from Carthamus tinctorius (safflower), in combination with reversed-phase ultra-high performance liquid chromatography (RP-UHPLC).

Repurposing of a monoamine oxidase A inhibitor‑heptamethine carbocyanine dye conjugate for paclitaxel‑resistant non‑small cell lung cancer.

Non‑small cell lung cancer (NSCLC) remains an intractable disease, which is primarily due to tumor metastasis and the acquisition of resistance to chemotherapy. Therefore, there is an urgent need for novel therapeutics to overcome these obstacles. It was recently demonstrated that upregulated expression of monoamine oxidase A (MAOA) contributes to the progression of NSCLC.

Comparisons of Functional Properties of Polysaccharides from under Three Culture Conditions.

is an edible cyanobacterium with excellent food and herbal values. It has been used as food in China for more than 2000 years. Many studies have been focused on improving the yield and bioactivity of polysaccharides although these have ignored the functional properties.

ROS Is a Factor Regulating the Increased Polysaccharide Production by Light Quality in the Edible Cyanobacterium Nostoc flagelliforme.

To explore the regulatory factor of light quality affecting exopolysaccharide (EPS) production, transcriptome analysis of Nostoc flagelliforme cells exposed to red light (R), blue light (B), and mixed light (B/R = 15:7) (BR) with white fluorescent light as control was performed. The differentially expressed genes mainly enriched in carbohydrate metabolism and energy metabolism. Significant enrichment in the oxidation-reduction process and energy metabolism indicated that intracellular redox homeostasis was disrupted.

Comparative proteomic analysis of Nostoc flagelliforme reveals the difference in adaptive mechanism in response to different ultraviolet-B radiation treatments.

Nostoc flagelliforme is a pioneer organism in the desert and highly resistant to ultraviolet B (UV-B) radiation, while the involved adaptive mechanism has not been fully explored yet. To elucidate the responsive mechanism, two doses of UV-B radiation (low: 1 W/m and high: 5 W/m) were irradiated for 6 h and 48 h, respectively, and their effects on global metabolism in N. flagelliforme were comprehensively investigated.

Effect of culture conditions on the physicochemical properties and antioxidant activities of polysaccharides from Nostoc flagelliforme.

Three polysaccharides (WL-CPS-1, NaCl-CPS-1 and Glu-CPS-1) were extracted and purified from Nostoc flagelliforme under normal, salt stress and mixotrophic culture conditions respectively. Their physicochemical properties and antioxidant activities were investigated. WL-CPS-1, NaCl-CPS-1 and Glu-CPS-1 chemical composition differed in sugar and uronic acid contents, and they were composed of nine constituent monosaccharides and one uronic acid with different ratios, with the average molecular weights of 1.

The physiological responses of terrestrial cyanobacterium to different intensities of ultraviolet-B radiation.

is a pioneer organism in the desert and exerts important ecological functions. The habitats of are characterized by intense solar radiation, while the ultraviolet B (UV-B) tolerance has not been fully explored yet. To evaluate the physiological responses of to UV-B radiation, three intensities (1 W m, 3 W m and 5 W m) were used, and the changes in photosynthetic pigments, cell morphology, mycosporine-like amino acids (MAAs) synthesis and cell metabolism were comparatively investigated.

Comparative research on tillable properties of diatomite-improved soils in the Yangtze River Delta region, China.

To improve soil texture and structure, techniques associated with physical, biological or chemical aspects are generally adopted, among which diatomite is an important soil conditioner. However, few studies have been conducted to investigate the physical, hydraulic and tillage performance of diatomite-improved soils. Consistency limits and compaction properties were investigated in this study, and several performance indicators were compared, such as the liquid limit, plastic limit and compactability, of silt, silt loam and silty-clay loam soils to which diatomite was added at volumetric ratios of 0%, 10%, 20%, and 30%.

Association of E-selectin gene polymorphisms with ischemic stroke in a Chinese Han population.

The E-selectin gene, a member of the selectin superfamily of adhesion molecules, plays an important role in the pathogenesis of thrombovascular diseases. The present study was designed to investigate the potential relationship between E-selectin gene polymorphisms and ischemic stroke in a Chinese Han population. Three hundred fourteen ischemic stroke patients and 389 unrelated healthy controls were recruited for the study.
