Mechanically Ultra-Robust Fluorescent Elastomer for Elaborating Auxetic Composite.

Fluorescent elastomers are predominantly fabricated through doping fluorescent components or conjugating chromophores into polymer networks, which often involves detrimental effects on mechanical performance and also makes large-scale production difficult. Inspired by the heteroatom-rich microphase separation structures assisted by intensive hydrogen bonds in natural organisms, an ultra-robust fluorescent polyurethane elastomer is reported, which features a remarkable fracture strength of 87.2 MPa with an elongation of 1797%, exceptional toughness of 678.

Effects of right ventricular remodeling in chronic thromboembolic pulmonary hypertension on the outcomes of balloon pulmonary angioplasty: a 2D-speckle tracking echocardiography study.

Background: Balloon pulmonary angioplasty (BPA) improves the prognosis of chronic thromboembolic pulmonary hypertension (CTEPH). Right ventricle (RV) is an important predictor of prognosis in CTEPH patients. 2D-speckle tracking echocardiography (2D-STE) can evaluate RV function.

Efficacy of balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension patients with pulmonary comorbidity.

Background: Balloon pulmonary angioplasty (BPA) is an established treatment for inoperable chronic thromboembolic pulmonary hypertension (CTEPH), but its efficacy in CTEPH patients with a pulmonary comorbidity has not been well-studied. Here, we compared post-BPA outcomes between CTEPH patients with and without chronic pulmonary disease at baseline and analyzed predictors of BPA success.

Methods: From August 2017 to October 2022, 62 patients with inoperable CTEPH who underwent BPA were consecutively enrolled and grouped based on the presence of a pulmonary comorbidity at baseline.

Patterned Manipulated Surface Based on Femtosecond Laser with Adjustable Wetting Speed and Directional Fluid Delivery.

Recently, due to the crucial roles of multifunctional liquid manipulation surfaces in biomedical transportation, microfluidics, and chemical engineering, the demand for controllable and functional aspects of directed liquid transportation has increased significantly. However, designing an intelligent manipulation surface that is easy to manufacture and fully functional remains an immense challenge. To address this challenge, a smart surface that can regulate the rate of liquid transport within a patterned channel by temperature is reported.

Transcriptome and coexpression network analysis reveals properties and candidate genes associated with grape ( L.) heat tolerance.

Temperature is one of the most important environmental factors affecting grape season growth and geographical distribution. With global warming and the increasing occurrence of extreme high-temperature weather, the impact of high temperatures on grape production has intensified. Therefore, identifying the molecular regulatory networks and key genes involved in grape heat tolerance is crucial for improving the resistance of grapes and promoting sustainable development in grape production.

Risk factors of disturbed sleep phases to posterior circulation cerebral infarctions: A single-center retrospective study.

Posterior circulation stroke differs from anterior circulation stroke in terms of etiological, clinical, and prognostic properties. Sleep architecture is impaired in patients with acute stroke, which may correlate with disease severity and outcome, and the correlation between the location of cerebral infarction (CI) and sleep phase disturbance remains unknown. This study aimed to assess the correlation between disturbed sleep phases in CI and posterior circulation cerebral infarction (PCCI).

Application of hybrid particle swarm and ant colony optimization algorithms to obtain the optimum homomorphic wavelet image fusion: Introduction.

Background: There are various applications for medical image fusion schemes in different medical clinics. Here, the generalized version of the homomorphic filtering technique involving the Fourier domain for image and signal processing is a proper method.

Methods: The methods on the wavelet transform proposes some advantages in the discretization of multimodality medical images fusion, conducted in the Fourier spectrum.

Effect of bacteria proportion on the fermentation of goat yoghurt with probiotic culture.

Background: Goat milk production in Shaanxi province is dominant in China, but the product is mainly infant formula and adult milk powder; product homogeneity is serious and has no goat yoghurt with probiotic culture.

Methods: The effect of bacteria proportion (1:3:1, 1:2:1, 1:1:1, 2:1:1, 3:1:1) on pH, acidity, and viable counts and sensory evaluation of goat milk fermented by probiotics including L. acidophilus, B.

Polymer-stabilized phospholipid vesicles with a controllable, pH-dependent disassembly mechanism.

In this letter, we report a facile method to prepare robust phospholipid vesicles using commonly available phospholipids that are stabilized via the formation of an interpenetrating, acid-labile, cross-linked polymer network that imparts a site for controlled polymer destabilization and subsequent vesicle degradation. The polymer network was formed in the inner lamella of the phospholipid bilayer using 2,2-di(methacryloyloxy-1-ethoxy)propane (DMOEP) and butyl methacrylate (BMA). Upon exposure to acidic conditions, the highly cross-linked polymer network was partially converted to smaller linear polymers, resulting in substantially reduced vesicle stability upon exposure to chemical and physical insults.
