Effects of gold and copper mining on the structure and diversity of the surrounding plant communities in Northeast Tiger and Leopard National Park.

Introduction: Northeast China Tiger and Leopard National Park is home to the largest and only breeding family of wild tigers and leopards in China. The mining of open-pit gold and copper mines in the core zone might affect the surrounding forest ecosystem and the survival activities of wild tigers and leopards.

Methods: In order to understand the impacts of gold and copper mining on the structure and diversities of the surrounding plant communities, the vegetation of the forest layer, shrub layer and herb layer of the forest community in the original forest area, mining area, tailings area and restoration area of the Northeast China Tiger and Leopard National Park were investigated, and the influence of plant community structure on species diversity was also evaluated.

The impact of utilizing oyster shell soil conditioner on the growth of tomato plants and the composition of inter-root soil bacterial communities in an acidic soil environment.

Introduction: The objective of this study is to examine the impact of various oyster shell soil conditioners, which are primarily composed of oyster shells, on the growth of tomatoes in acidic soil. Moreover, the aim of this investigation is to analyze the variety and structure of soil bacterial populations in close proximity to tomato roots while also contributing to the understanding of the physical, chemical, and biological mechanisms of oyster shell soil conditioners.

Methods: Tomato plants were grown in acidic red soil in three groups: a control group and a treatment group that used two types of oyster shell soil conditioners, OS (oyster shell powder) and OSF (oyster shell powder with organic microbial fertilizer).

Metabolic flux analysis of coenzyme Q synthesized by Rhodobacter sphaeroides under the influence of different pH regulators.

Coenzyme Q (CoQ) is crucial for human beings, especially in the fields of biology and medicine. The aim of this experiment was to investigate the conditions for increasing CoQ production. At present, microbial fermentation is the main production method of CoQ, and the production process of microbial CoQ metabolism control fermentation is very critical.

Construction of AI Environmental Music Education Application Model Based on Deep Learning.

The art of music, which is a necessary component of daily life and an ideology older than language, reflects the emotions of human reality. Many new elements have been introduced into music as a result of the quick development of technology, gradually altering how people create, perform, and enjoy music. It is incredible to see how actively AI has been used in music applications and music education over the past few years and how significantly it has advanced.

, a new edible bolete from China, is associated with insects and plants.

is described as new based on collections from southwest China. Phylogenetic analyses of nuclear rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS) and portions of nuclear 28S rDNA (28S), translation elongation factor 1-alpha (), and the largest and second largest subunits of RNA polymerase II () support as a novel species in the genus (Boletinellaceae, Boletales).

Smart phase transformation system based on lyotropic liquid crystalline@hard capsules for sustained release of hydrophilic and hydrophobic drugs.

Smart phase transformation systems@hard capsule (SPTS@hard capsule) based on lyotropic liquid crystalline (LLC) were developed for oral sustained release in this study. Doxycycline hydrochloride (DOXY) and meloxicam (MLX) were used as hydrophilic and hydrophobic model drug, respectively. Two systems were added with different additives, that is, gelucire 39/01, PEG 1000 and Tween 80 to adjust their melting point and release profiles.

Shapes the Ectomycorrhizosphere Microbial Communities of .

In this study, eight-month-old ectomycorrhizae of with were synthesized to explore the influence of colonization on the soil properties and the microbial communities associated with during the early symbiotic stage. The results showed that the bacterial richness and diversity in the ectomycorrhizae were significantly higher than those in the control roots, whereas the fungal diversity was not changed in response to colonization. was the dominant taxon (82.

[The effects and mechanisms of BTBD10 on the proliferation of islet beta cell].

Objective: To explore the role of BTBD10 overexpression in the proliferation of insulinoma cell line INS-1 and its mechanism.

Methods: The recombined expression plasmid of pcDNA4.0-BTBD10 was constructed by gene cloning technique and was transfected into INS-1 cell by lipofectamine 2000.

[Diagnostic values of self-assessment tool for Asians for osteoporosis in aged men].

Objective: To evaluate the diagnostic values of osteoporosis self-assessment tool for Asians (OSTA) in aged men.

Methods: Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry (DXA) in 382 male outpatients. Their data were collected.

[Preparation, characterization and content determination of cubic phase gel containing capsaicin].

Objective: To prepare the cubic phase gel containing capsaicin and characterize its properties.

Method: The cubic phases gel composed of glycerol monoolein, capsaicin and water was made by self-emulsion technology. The characterization of cubic phase gel was carried out by cross-polarizing light microscopy (CPLM) and Small Angle X-Ray Scattering (SAXS).
