A turn-on fluorescent nanosensor for HS detection and imaging in inflammatory cells and mice.

Hydrogen sulfide (HS) is an endogenously generated gaseous signaling molecule and is known to be involved in the occurrence and development of inflammation. To better understand its physiological and pathological process of inflammation, reliable tools for HS detection in living inflammatory models are desired. Although a number of fluorescent sensors have been reported for HS detection and imaging, water-soluble and biocompatibility nanosensors are more useful for imaging in vivo.

The physiological and pathological results of OONO are related to the local concentration of ONOO. Therefore, to develop of a simple, rapid and reliable OONO detection tool is badly needed.

Broadband and CMOS-compatible polarization splitter and rotator built on a silicon nitride-on-silicon multilayer platform.

A broadband and CMOS-compatible polarization beam splitter and rotator (PSR) built on the silicon nitride-on-silicon multilayer platform is presented. The PSR is realized by cascading a polarization beam splitter and a polarization rotator, which are both subtly constructed with an asymmetrical directional coupler waveguide structure. The advantage of this device is that the function of PSR can be directly realized in the SiN layer, providing a promising solution to the polarization diversity schemes in SiN photonic circuits.

Effects of Co-Inoculating spp. with on Atmospheric Nitrogen Fixation in Soybeans ( (L.)).

Crop production encounters challenges due to the dearth of nitrogen (N) and phosphorus (P), while excessive chemical fertilizer use causes environmental hazards. The use of N-fixing microbes and P-solubilizing microbes (PSMs) can be a sustainable strategy to overcome these problems. Here, we conducted a greenhouse pot experiment following a completely randomized blocked design to elucidate the influence of co-inoculating N-fixing bacteria () and PSMs ( and ) on atmospheric N-fixation, growth, and yield.

Spatial and nonlinear effects of new-type urbanization and technological innovation on industrial carbon dioxide emission in the Yangtze River Delta.

The purpose of this paper is to quantify the level of new-type urbanization and unravel the spatial and nonlinear effects of new-type urbanization and technological innovation on industrial carbon emissions. Although the impact of traditional urbanization levels on carbon emissions has been widely studied, there is still a huge room for optimization, and the impact of new-type urbanization on carbon emissions has not yet been clarified. Selecting 37 cities in the Yangtze River Delta as a research sample, this paper measures the new-type urbanization based on an evaluation system we build.

Integrated transcriptome and hormonal analysis of naphthalene acetic acid-induced adventitious root formation of tea cuttings (Camellia sinensis).

Background: Tea plant breeding or cultivation mainly involves propagation via cuttings, which not only ensures the inheritance of the excellent characteristics of the mother plant but also facilitates mechanized management. The formation of adventitious root (AR) determines the success of cutting-based propagation, and auxin is an essential factor involved in this process. To understand the molecular mechanism underlying AR formation in nodal tea cuttings, transcriptome and endogenous hormone analysis was performed on the stem bases of red (mature)- and green (immature)-stem cuttings of 'Echa 1 hao' tea plant as affected by a pulse treatment with naphthalene acetic acid (NAA).

Necessity of external iliac lymph nodes and inguinal nodes radiation in rectal cancer with anal canal involvement.

Background And Purpose: We aimed to explore the necessity of the external iliac lymph nodes (EIN) along with inguinal nodes (IN) region in clinical target volume (CTV) for rectal carcinomas covering the anal canal region.

Materials And Methods: This research premise enrolled 399 patients who had primary low rectal cancer detected below the peritoneal reflection via magnetic resonance imaging (MRI) and were treated with neoadjuvant radiotherapy (NRT), without elective EIN along with IN irradiation. We stratified the patients into two groups based on whether the lower edge of the rectal tumor extended to the anal canal (P group, n = 109) or not (Rb group, n = 290).

Berberine suppresses cecal ligation and puncture induced intestinal injury by enhancing Treg cell function.

The gut is hypothesized to be the "motor" of critical illness and plays an important role in the development of sepsis. Berberine (BBR) is an alkaloid compound extracted from herbs, which has anti-inflammatory, anti-oxidative effects and can be used in intestinal infectious diseases and inflammatory bowel disease (IBD). BBR could promote differentiation of Treg cells which play a key role in maintaining intestinal immune homeostasis.
