The monitoring of peripheral circulation, as indicated by the capillary refill time, is a sensitive and accurate method of assessing the microcirculatory status of the body. It is a widely used tool for the evaluation of critically ill patients, the guidance of therapeutic interventions, and the assessment of prognosis. In recent years, there has been a growing emphasis on microcirculation monitoring which has led to an increased focus on capillary refill time.

Herein, a flexible rolling triboelectric nanogenerator with a bionic gill cover structure (GFR-TENG) to harvest steady low-velocity water flow energy is proposed. The dielectric material of the GFR-TENG is eight flexible hollow fluorinated ethylene propylene (FEP) pipes, which guarantees that rolling friction is formed between the dielectric material and copper electrode.

Choroid plexus cerebrospinal fluid (CSF) hypersecretion, obliterative arachnoiditis occluding the arachnoid villi, lymphatic obstruction, subarachnoid fibrosis, and glymphatic system injury are considered the main pathological mechanisms of hydrocephalus after SAH. Although the mechanisms of hydrocephalus after SAH are increasingly being revealed, the clinical prognosis of SAH still has not improved significantly.

We describe steps for inducing cardiac reprogramming in vitro, validating condensate formation ability of Hdac4, and observing Hdac4 condensates during reprogramming. We then detail procedures for disrupting these condensates using PC14-3-3 activation strategies.

This article systematically analyzes the differences in diagnostic and treatment principles, material composition, new drug development pathways, efficacy cognition, and evaluation methodology between Chinese and Western medicine from the underlying logic of medical perspective. On this basis, it integrates the evidence elements of clinical experience, experimental research, and clinical trials, and for the first time proposes and establishes a new strategy and methodology for the evaluation of the effectiveness of TCM: the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(iEC-Eff), forming an integrated evaluation and confirmation model of "clinical experience-experimental research-clinical trial" for the effectiveness of TCM.

While the output performance of TENGs is still not high enough, which limits its practical application. Here, a poly(vinylidene fluoride) (PVDF)/fluorinated ethylene propylene nanoparticles (FEP NPs) porous nanofiber (PFPN) membrane with waterproof, breathable, surface superhydrophobic and high tribo-negative properties is proposed for achieving high-performance of TENGs.
View Article and Find Full Text PDFTriboelectric nanogenerators (TENGs) represent a promising technology for energy harvesting and self-powered sensing with a wide range of applications. Despite their potential, challenges such as the need for cost-effective, large-area electrodes and engineering sustainable triboelectric materials remain, especially given the impending restrictions on single-use engineering plastics in Europe. To address these challenges, engineering nano-graphite-coated paper is presented as a sustainable and high-performance alternative for triboelectric layers.

With the goal of shedding light on the complex regulatory processes governing caffeine biosynthesis in tea plants, liquid chromatography coupled with mass spectrometry (LC-MS), transcriptomics, and small RNA analyses were employed on diverse tea cultivars such as 'Jianghua Kucha' [including 'Xianghong 3' (XH3H) and 'Kucha 3' (KC3H)], 'Fuding Dabaicha' (FDDB), 'Yaoshan Xiulv' (YSXL), and 'Bixiangzao' (BXZ). The results showed that the caffeine level in 'Jianghua Kucha' was significantly higher than that in other tea plant cultivars.

Background: Traumatic brain injury (TBI) is a major public health concern with high morbidity and mortality rates. Secondary brain injury, marked by inflammatory responses and apoptosis, worsens TBI outcomes. The endoplasmic reticulum stress (ERS) response has been implicated in secondary brain injury, with Glutamine Rich 1 Gene (QRICH1) emerging as a potential mediator.

However, the drivers that constitute the species-specific plant elementome, as well as the bivariate bioelemental correlations in determining the stability of different bioelements are yet unclear. Based on 1058 leaf observations of 84 plant species from 232 wetlands across large environmental gradients, we found that bioelements with higher concentration were more stable and evolutionary constrained.
View Article and Find Full Text PDFAqueous solution experiences either crystallization or vitrification as being cooled, yet the mechanism of this bifurcation is confused. Since the glass-transition temperature T is much lower than the melting temperature, we herein propose an entropy-driven glass-forming liquid (EDGFL) as an attractive concept to develop anti-freezing electrolytes. The T is delicately modulated via regulating local structural orders to avoid the energy-driven ice crystallization and enter an entropy-driven glass transition, which can be theoretically explained by the competitive effect between tetrahedral entropy of water and pair correlation entropy related to ions.
