Previous studies have shown that a spiritual climate enhances psychological empowerment, however, the relationship between them among the nursing population remains unclear.

Transient Receptor Potential Channels in Sensory Mechanisms of the Lower Urinary Tract.

Background: Urine storage and excretion require a network of interactions in the urinary tract and the central nervous system, which is mediated by a reservoir of water in the bladder and the outlet to the bladder neck, urethra, and external urethral sphincter. Through communicating and coordinating each other, micturition system eventually showed a switch-like activity pattern.

Summary: At cervicothoracic and lumbosacral spine, the spinal reflex pathway of the lower urinary tract (LUT) received mechanosensory input from the urothelium to regulate the bladder contraction activity, thereby controlled urination voluntarily.

Engineering liquid metal-based nanozyme for enhancing microwave dynamic therapy in breast cancer PDX model.

Backgrounds: The novel concept of microwave dynamic therapy (MDT) solves the problem of incomplete tumor eradication caused by non-selective heating and uneven temperature distribution of microwave thermal therapy (MWTT) in clinic, but the poor delivery of microwave sensitizer and the obstacle of tumor hypoxic microenvironment limit the effectiveness of MDT.

Results: Herein, we engineer a liquid metal-based nanozyme LM@ZIF@HA (LZH) with eutectic Gallium Indium (EGaIn) as the core, which is coated with CoNi-bimetallic zeolite imidazole framework (ZIF) and hyaluronic acid (HA). The flexibility of the liquid metal and the targeting of HA enable the nanozyme to be effectively endocytosed by tumor cells, solving the problem of poor delivery of microwave sensitizers.

How to reduce the risk of cervicalgia and low back pain in obese individuals: A mendelian randomization study.

Obesity is associated with cervicalgia and low back pain (LBP), but the specific role and how to reduce the risk of neck pain and low back pain are not clear. The Mendelian randomization analysis was used to investigate the causal relationship between obesity and cervicalgia and LBP, as well as the effect of possible mediating factors. Then, causal associations were estimated using sensitivity analysis.

A core-shell liquid metal-Cu nanoparticle with glutathione consumption an replacement strategy for tumor combination treatment of chemodynamic, microwave dynamic and microwave thermal therapy.

The presence of high content glutathione (GSH) provides an effective "protective shield" for tumor cells, which undoubtedly is a huge impediment to reactive oxygen species (ROS)-based treatment. Fortunately, divalent copper (Cu) can not only consume GSH, destroying the protection mechanism of GSH, but also can be reduced to Cu with excellent Fenton-like reaction activity. Hence, capitalizing on the properties of liquid metals, we introduced Cu with three different valances an replacement reaction.

High Biocompatible Poly(lactic-co-glycolic acid)-Based Nanosensitizer With Magnetic Resonance Imaging Capacity for Tumor Targeted Microwave Hyperthermia and Chemotherapy.

Microwave (MW) hyperthermia has been widely studied in tumor therapy, while the lack of specificity, and the potential toxicity induced by instability or difficulty in degradation of existed MW thermal sensitizers still limits the application. Herein, a new biocompatible Poly(lactic-co-glycolic acid) (PLGA)-based nanosensitizer of Dtxl-Gd@PLGA-PEG-TPP (DGPPT) with capacities of magnetic resonance (MR) imaging and mitochondrial targeting for MW hyperthermia combined with chemotherapy was constructed via a double emulsion solvent evaporation method. The modified TPP significantly enhanced the specificity of sensitizer for targeting mitochondria, a heat-sensitive energy supply plant in cells.

Photothermal photodynamic therapy and enhanced radiotherapy of targeting copolymer-coated liquid metal nanoparticles on liver cancer.

The maximized therapeutic efficacy in tumor treatment can be achieved with combination therapy. Herein, a metronidazole (MN) and RGD peptides were linked with the copolymer chains of polyacrylic acid (PAA) and polyethylene glycol (PEG) by condensation and Michael addition reactions, respectively, named as RGD-PEG-PAA-MN. Subsequently, liquid-metal (LM) nanoparticles broken by ultrasonication were coated with modified copolymer, forming RGD-PEG-PAA-MN@LM nanoparticles.

Recent progress in Van der Waals 2D PtSe.

As a new member in two-dimensional (2D) transition metal dichalcogenides (TMDCs) family, platinum diselenium (PtSe) has many excellent properties, such as the layer-dependent band gap, high carrier mobility, high photoelectrical coupling, broadband response, etc, thus it shows good promising application in room temperature photodetectors, broadband photodetectors, transistors and other fields. Furthermore, compared with other TMDCs, PtSeis chemical inert in ambient, showing nano-devices potential with higher performance and stability. However, up to now, the synthesis and its device applications are in its early stage.

The resulting grass-like nanowire array structure greatly promotes the utilization rate of active materials.

Dual-Functional Supernanoparticles with Microwave Dynamic Therapy and Microwave Thermal Therapy.

The cytotoxic reactive oxygen species (ROS) generated by photoactivated sensitizers have been well explored in tumor therapy for nearly half a century, which is known as photodynamic therapy (PDT). The poor light penetration depth severely hinders PDT as a primary or adjuvant therapy for clinical indication. Whereas microwaves (MWs) are advantageous for deep penetration depth, the MW energy is considerably lower than that required for the activation of any species to induce ROS generation.

Multifunctional and flexible ZrO-coated EGaIn nanoparticles for photothermal therapy.

With extensive investigations involving liquid metals (LMs), Ga-based LMs have attracted increasing attention from biomedical researchers because of their good biocompatibility, ideal fluidity, and high thermal conductivity. LMs employed in cancer treatment suffer from high surface tension, thereby yielding unstable nanoparticles (NPs). Here, ZrO2 is coated onto LM NPs to form a stable core-shell nanostructure.

The nutritional herb inhibits the growth in a model for the Luminal A molecular subtype of breast cancer.

The Luminal A subtype of breast cancer expresses the estrogen receptor (ER)-α and progesterone receptor (PR), but not the human epidermal growth factor receptor (HER)-2 oncogene. This subtype of breast cancer responds to endocrine therapy involving the use of selective estrogen receptor modulators and/or inhibitors of estrogen biosynthesis. However, these therapeutic agents are frequently associated with long-term systemic toxicity and acquired tumor resistance, emphasizing the need to identify non-toxic alternative treatments for chemo-endocrine therapy responsive breast cancer.

Methods: A retrospective study was performed on the clinical data of 61 patients with NBD and hyperreflexia who were treated and followed up between July 2008 and June 2013. There were 36 males and 25 females, aged 6-23 years (mean, 10 years).

Topological Vulnerability Evaluation Model Based on Fractal Dimension of Complex Networks.

With an increasing emphasis on network security, much more attentions have been attracted to the vulnerability of complex networks. In this paper, the fractal dimension, which can reflect space-filling capacity of networks, is redefined as the origin moment of the edge betweenness to obtain a more reasonable evaluation of vulnerability. The proposed model combining multiple evaluation indexes not only overcomes the shortage of average edge betweenness's failing to evaluate vulnerability of some special networks, but also characterizes the topological structure and highlights the space-filling capacity of networks.
