Polarity and fluorescent fractions of manure dissolved organic matter could affect differently the adsorption and desorption of antibiotics in soils.

The impacts of manure dissolved organic matter (DOM) on the adsorption and desorption of veterinary antibiotics in soils have not been fully explored. In this study, the effects of pig manure (PM) DOM and its hydrophilic and hydrophobic fractions on antibiotic adsorption and subsequent desorption in three topsoils of bamboo stands under different fertilization conditions (control, with heavy manure application, and with heavy manure application suspended) were examined by batch experiments, with the aid of excitation-emission matrix fluorescence spectroscopy, Fourier transformed infrared spectroscopy, and X-ray photoelectron spectroscopy. The addition of 100 mg-C L PM DOM was found to increase the adsorption (in terms of the Freundlich affinity coefficient (K)) of florfenicol by 71.

Seasonal impacts of Kuroshio intrusion on pico-phytoplankton dynamics near the Changjiang River estuary.

The strong western Pacific boundary current of the Kuroshio significantly affects the oceanographic and ecological processes of the East China Sea through its branches. To understand the seasonal variation of Kuroshio intrusion and its ecological effects, 10 cruises were conducted from February 2015 to January 2016 in the waters adjacent to the Changjiang River estuary to collect hydrological data and abundances of phytoplankton assemblages of Prochlorococcus (Pro), Synechococcus (Syn) and picoeukaryotes. High salinity bottom water representing the Nearshore Kuroshio Branch Current (NKBC) appeared in the spring, peaked in the summer, and then almost disappeared at the end of the autumn.

Construction and validation of a pancreatic cancer prognostic model based on genes related to the hypoxic tumor microenvironment.

Background: Pancreatic cancer is one of the most lethal malignancies, characterized by poor prognosis and low survival rates. Traditional prognostic factors for pancreatic cancer offer inadequate predictive accuracy, often failing to capture the complexity of the disease. The hypoxic tumor microenvironment has been recognized as a significant factor influencing cancer progression and resistance to treatment.

Dissociated urethral plate Onlay and standard Onlay urethroplasty for mid-distal hypospadias: A comparative study.

Background: Urethral plate (UP) reserved Onlay urethroplasty is currently used widely in mid-distal hypospadias. However, for children with 15-30° residual curvature after degloving, only dorsal tunica albuginea plication is performed to correct penile ventral curvature (VC), and long-term follow-up showed a high recurrence rate of penile curvature. We developed a modified Onlay urethroplasty, which dissociates the UP and completely removes the tissue beneath the UP to fully correct penile curvature.

Glutaminolysis is a Potential Therapeutic Target for Kidney Diseases.

Altered glutamine metabolism is a prominent feature in different kidney diseases.

Label-free and ultrasensitive detection of environmental lead ions based on spatially localized DNA nanomachines driven by hyperbranched hybridization chain reaction.

A label-free fluorescent sensing strategy for the rapid and highly sensitive detection of Pb was developed by integrating Pb DNAzyme-specific cleavage activity and a tetrahedral DNA nanostructure (TDN)-enhanced hyperbranched hybridization chain reaction (hHCR). This strategy provides accelerated reaction rates because of the highly effective collision probability and enriched local concentrations from the spatial confinement of the TDN, thus showing a higher detection sensitivity and a more rapid detection process. Moreover, a hairpin probe based on a G-triplex instead of a G-quadruplex or chemical modification makes hybridization chain reaction more controlled and flexible, greatly improving signal amplification capacities and eliminating labeled DNA probes.

Imbalance of mitochondrial quality control regulated by STING and PINK1 affects cyfluthrin-induced neuroinflammation.

Nervous system diseases are a global health problem, and with the increase in the elderly population around the world, their incidence will also increase. Harmful substances in the environment are closely related to the occurrence of nervous system diseases. China is a large agricultural country, and thus the insecticide cyfluthrin has been widely used.

Biochar reduces antibiotic transport by altering soil hydrology and enhancing antibiotic sorption.

The performance of biochar (BC) in reducing the transport of antibiotics under field conditions has not been sufficiently explored. In repacked sloping boxes of a calcareous soil, the effects of different BC treatments on the discharge of three relatively weakly sorbing antibiotics (sulfadiazine, sulfamethazine, and florfenicol) via runoff and drainage were monitored for three natural rain events. Surface application of 1 % BC (1 %BC-SA) led to the most effective reduction in runoff discharge of the two sulfonamide antibiotics, which can be partly ascribed to the enhanced water infiltration.
