A triple-channel sensor array utilizing fluorescent carbon dots for simultaneous discrimination and detection of multiple fluoroquinolones.

The presence of fluoroquinolones (FQs) residues in food and the environment has prompted concerns regarding food safety and public health. Consequently, it is of great significance to analyze the types and levels of FQs present. However, the majority of studies have concentrated on the specific detection of individual FQs, with a notable absence of high-throughput and rapid analysis methods for the simultaneous detection of multiple FQs that may coexist in food and the environment.

Establishment of a logistic regression model nomogram for clinicopathological characteristics and risk factors with axillary lymph node metastasis in T1 locally advanced breast cancer: a retrospective study.

Background: Although the research reports on locally advanced breast cancer (LABC) are increasing year by year, there are few reports on T1 LABC axillary lymph node metastasis (ALNM). By establishing a prediction model for T1 LABC ALNM, this study provides a reference value for the probability of ALNM of related patients, which helps clinicians to develop a more effective and individualized treatment plan for LABC.

Methods: Cases with pathologically confirmed T1 breast cancer (BC) between 2010 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database were identified.

Compensatory effects of other olfactory genes after CRISPR/cas9 editing of BmOR56 in silkworm, Bombyx mori.

Potential interaction ways between BmOR56 and cis-Jasmone were explored, which included some crucial amino acids such as Gln172, Val173, Ser176, Lys182, His322, and Arg345.

MXene/Nitrogen-Doped Carbon Nanosheet Scaffold Electrode toward High-Performance Solid-State Zinc Ion Supercapacitor.

While MXene is widely used as an electrode material for supercapacitor, the intrinsic limitation of stacking caused by the interlayer van der Waals forces has yet to be overcome. In this work, a strategy is proposed to fabricate a composite scaffold electrode (MCN) by intercalating MXene with highly nitrogen-doped carbon nanosheets (CN). The 2D structured CN, thermally converted and pickling from Zn-hexamine (Zn-HMT), serves as a spacer that effectively prevents the stacking of MXene and contributes to a hierarchically scaffolded structure, which is conducive to ion movement; meanwhile, the high nitrogen-doping of CN tunes the electronic structure of MCN to facilitate charge transfer and providing additional pseudocapacitance.

[Relationship between acupuncture sensations of and different organizational structures of acupoint area].

Acupuncture sensation, as one of the essential signs of (arrival of ), is closely associated with curative effect. With systematically reviewing the literature regarding relationship between acupuncture sensations of and different organizational structures of acupoint area (skin, connective tissue, muscles, nerves and blood vessels), it is believed that acupuncture sensation of is the product of various organizational structures in acupoint area, which is closely related to the nervous system. The sensations sensed by the hands of acupuncturists, which is called sense of needle stagnation, maybe caused by the contraction of muscles in the acupoint area during the process of needle manipulation.

[Impact of different anesthetic states on acupuncture-mediated modulation of autonomic nervous system in animal studies].

Acupuncture therapy has a positive role in the prevention and treatment of some related diseases by regulating autonomic nervous function. But it has been found in experimental researches that the modulatory effects of acupuncture on autonomic nervous system are not always consistent with each other. Because in the animal studies on the mechanism of acupuncture intervention, the anesthetic agent has to be used and definitely affects the activities of the autonomic nervous system while playing its pharmacological effects.

Bombyx mori presents several types of egg color mutations, all of which have been extensively discussed in sericulture. While the red egg mutation has been previously observed, lethal red-egg mutants have not been reported. In the present work, the red egg mutant Fuyin-lre (Fuyin-lethal red egg) was discovered from the Fuyin germplasm resource of B.

[Genetic analysis and gene mapping of two novel quail-like mutants from the silkworm (Bombyx mori)].

Two novel body marking mutants were discovered during silkworm (Bombyx mori) breeding. The mutants have no obvious eye-spots compared with normal marking (+) individuals, but their star spots and semilunar markings on dorsal sides are normal, and there are dots and lines with longitudinal wave markings on dorsal sides of the 6th to 7th abdominal segments which consist quail markings in between star spots and semilunar markings. The whole body markings are very similar to that of quail mutant (q); thus these mutants are named as quail-like mutants (q-l).
