The mango bacterial black spot altered the endophyte community structure and diversity.

Mango bacterial black spot is a major disease limiting mango production, which is now causing increasingly severe economic losses. In this study, we analyzed the differences in the composition and structure of bacterial and fungal communities in the pulp and leaves between the healthy mangoes of variety Kate and those affected by bacterial black spot, and attempted to explore potential biocontrol microorganisms for mangoes. The results showed there existed significant differences in microbial communities, the bacterial Stenotrophomonas, Curtobacterium, Massilia and fungous Penicillium, Alternaria, Aureobasidiu showed great abundance both in pulps and leaves.

sp. nov., a chemolithoautotrophic sulphur-oxidizing and nitrogen-fixing bacterium isolated from freshwater.

A sulphur-oxidizing and nitrogen-fixing bacterium, designated strain LS2, was isolated from freshwater collected from the Pearl River in Guangzhou, PR China. The strain was an obligate chemolithoautotroph, utilizing reduced sulphur compounds (sulphide, sulphite, elemental sulphur, thiosulphate and tetrathionate) as energy sources and electron donors. Diazotrophic growth of strain LS2 was observed at 15-40 °C, pH 5-9, with a NaCl concentration range of 0-0.

Soli-enabled noncontact heart rate detection for sleep and meditation tracking.

Heart rate (HR) is a crucial physiological signal that can be used to monitor health and fitness. Traditional methods for measuring HR require wearable devices, which can be inconvenient or uncomfortable, especially during sleep and meditation. Noncontact HR detection methods employing microwave radar can be a promising alternative.

The complete mitochondrial genome of okra (Abelmoschus esculentus): using nanopore long reads to investigate gene transfer from chloroplast genomes and rearrangements of mitochondrial DNA molecules.

Background: Okra (Abelmoschus esculentus L. Moench) is an economically important crop and is known for its slimy juice, which has significant scientific research value. The A.

Establishment and Optimization of Molecular Cytogenetic Techniques (45S rDNA-FISH, GISH, and Fiber-FISH) in Kiwifruit ( Lindl.).

The kiwifruit () has long been regarded as "the king of fruits" for its nutritional importance. However, the molecular cytogenetics of kiwifruit has long been hampered because of the large number of basic chromosome ( = 29), the inherent small size and highly similar morphology of metaphase chromosomes. Fluorescence hybridization (FISH) is an indispensable molecular cytogenetic technique widely used in many plant species.

Comparative Metabolomics Study of (Sweet) Nakai from Different Geographical Regions.

(Sweet) Nakai () is not only a Chinese herbal medicine but also a functional food widely planted in China. Its fruits are used to treat many diseases or can be processed into food products. This study aims to find key metabolic components, distinguish the differences between geographical regions and find more medicinal and edible values of fruits.

Transcranial Direct Current Stimulation (tDCS) over the Left Dorsal Lateral Prefrontal Cortex in Children with Autism Spectrum Disorder (ASD).

Recently, transcranial direct current stimulation (tDCS) has been applied to relieve symptoms in individuals with autism spectrum disorder (ASD). In this prospective, parallel, single-blinded, randomized study, we investigate the modulation effect of three-week tDCS treatment at the left dorsal lateral prefrontal cortex (DLPFC) in children with ASD. 47 children with ASD were enrolled, and 40 (20 in each group) completed the study.

[An approach to a negative pressure automatic control system in electronic endoscope].

Objective: The work presented here was to research into a kind of automatic control system that would be automatically linked to the working status of electronic endoscope.

Methods: The image video output signal and signal of negative pressure sensor were used to be a sampling signal of automatic control circuit. An electronic switch of automatic control circuit was challenged the manual control device of the negative pressure system.

Optical characterization of a GaAs/In(0.5)(AlxGa(1-x))(0.5)P/GaAs heterostructure cavity by piezoreflectance spectroscopy.

Optical properties of a lattice matched GaAs/In(0.5)(AlxGa(1-x))(0.5)P/GaAs heterostructure cavity have been characterized using piezoreflectance (PzR) measurements in the temperature range between 20 and 300 K.
