A Europium Metal-Organic Framework and Its Polymer Composite Membrane as Switch-Off Fluorescence Sensors for Antibiotic Detection in Lake Water.

The detection of antibiotic residues is of great significance in monitoring their overuse in healthcare, livestock and poultry farming, and agricultural production. Herein, EuCl and 4,4'-dicarboxyl-diphenoxyethene (HDPOE) ionothermally reacted in 1-methyl-3-butylimidazolium chloride to give a europium metal-organic framework (Eu-DPOE). Eu-DPOE shows different fluorescence quenching rates for sensing eight antibiotics under different excitation wavelengths.

Dynamic topography analysis of the cornea and its application to the diagnosis of keratoconus.

Propose: To establish a dynamic topography analysis method which simulates the dynamic biomechanical response of the cornea and reveals the variations of such response within the corneal surface, and thereafter to propose and clinically evaluate new parameters for the definite diagnosis of keratoconus.

Methods: 58 normal (Normal) and 56 keratoconus (KC) subjects were retrospectively included. Personalized corneal air-puff model was established using corneal topography data by Pentacam for each subject, and the dynamic deformation under air-puff loading was simulated using finite element method, which then enabled calculations of corneal biomechanical parameters of the entire corneal surface along any meridian.

Tim-1 B cells suppress T cell interferon-gamma production and promote Foxp3 expression, but have impaired regulatory function in coronary artery disease.

Atherosclerosis and its associated coronary artery disease (CAD) represent another chronic low-grade inflammatory disorder. Regulatory B cells (Bregs) possess essential functions in maintaining peripheral tolerance and inhibiting pathogenic inflammation through IL-10. Here, we investigated one subset of Bregs, Tim-1 B cell, and its role in atherosclerosis and CAD patients.

[Effects of ulinastatin on cardiac function and myocardial p38MAPK in rats with septic shock].

Objective: To investigate the effect of different doses of ulinastatin (UTI) on the cardiac function and myocardial expression of p38 mitogen-activated protein kinase (p38MAPK) in septic rats.

Methods: Forty male SD rats were randomized equally into 5 groups, namely the control group (group A), sham-operated group (group B), sepsis group (group C), low-dose UTI group (group D), and high-dose UTI group (group E). Rat models of sepsis were established by cecal ligation and puncture (CLP), At 24 h after successful modeling, the left ventricle ejection fraction (LVEF) and fractional shortening (LVFS) were evaluated, and the myocardium of the left ventricle was sampled to examine the expression of the expressions of p38MAPK and p-p38MAPK using Western blotting.

Contrast-enhanced ultrasound for blunt hepatic trauma: an animal experiment.

Objective: The aim of this study was to study the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of active hemorrhage and intraparenchymal lesions in blunt hepatic trauma versus conventional ultrasound (US).

Methods: Twenty heparinized and anesthetized domestic pigs have been created to animal models with blunt hepatic trauma by a special impacting device. Conventional US and CEUS were performed to determine if hepatic traumas were present.

[Transvaginal sonography and transabdominal sonography in the diagnosis of ectopic pregnancy in the fallopian tubal: a comparative study in 38 cases].

Objective: To compare the accuracy of transvaginal sonography (TVS) and transabdominal sonography (TAS) in the diagnosis of ectopic pregnancy occurring in the fallopian tubal.

Methods: Thirty-eight patients with ectopic pregnancy in the fallopian tube were examined by TAS with moderately filled bladder, followed by reexamination with TVS with the bladder emptied. The manifestations in the 2 imaging examinations were compared.
