Smart Bandage Based on a ZIF-8 Triboelectric Nanogenerator for In Situ Real-Time Monitoring of Drug Concentration.

For chronic wounds, frequent replacement of bandages not only increases the likelihood of secondary damage and the risk of cross infection but also wastes medication. Therefore, in situ real-time monitoring of the concentrations of residual drugs in bandages is crucial. Here, we propose a novel strategy that combines a triboelectric nanogenerator (TENG) with medical bandages to develop a smart bandage based on zeolite imidazolate framework TENG.

A potential immunotherapy target for breast cancer: parenchymal and immune-stromal expression of the NLRP3 inflammasome pathway.

Background: The NOD-, LRR- and pyrin domain‑containing 3 (NLRP3) inflammasome is a critical component of the innate immune system. It has been known to play an important role in the carcinogenesis and prognosis of breast cancer patients. While the clinical evidence of the relationship between NLRP3 inflammasome activation and long-term survival is still limited, the possible roles of parenchymal or immune-stromal cells of breast cancer tissues in contributing to such carcinogenesis and progression still need to be clarified.

A multi-agent model of traffic simulation around urban scenic spots: From the perspective of tourist behaviors.

This paper proposes a multi-agent model to simulate the traffic around urban scenic spots within tourist cities, where a newly added tourist agent is involved. Due to the flexible nature of tour travel demand and the impact of the real-time information of mobile application on tourist behaviors, there is an interactive process between tourists' travel behaviors and traffic state around scenic spots. To validate the proposed model, a case study of the Yanwu Road section at the Qunxian Gate of Xiamen University is conducted.

Construction and analysis of circular RNA-associated competing endogenous RNA network in the hippocampus of aged mice for the occurrence of postoperative cognitive dysfunction.

Circular RNAs are highly stable single-stranded circular RNAs and enriched in the brain. Previous studies showed that circRNAs, as part of competing endogenous RNAs (ceRNAs) network, play an important role in neurodegenerative and psychiatric diseases. However, the mechanism of circRNA-related ceRNA networks in postoperative cognitive dysfunction (POCD) has not been elucidated yet.

Effects of dezocine on morphine tolerance and opioid receptor expression in a rat model of bone cancer pain.

Background: Clinically, the coadministration of opioids to enhance antinociception and decrease tolerance has attracted increasing research attention. We investigated the effects of dezocine, a mu- and kappa-opioid receptor agonist/antagonist, on morphine tolerance and explored the involvement of opioid receptor expression in a rat model of bone cancer pain.

Methods: Thermal nociceptive thresholds were measured after the subcutaneous injection of morphine (10 mg/kg) alone or combined with dezocine (10 or 1 mg/kg) for 7 consecutive days.

Donepezil prevents morphine tolerance by regulating N-methyl-d-aspartate receptor, protein kinase C and CaM-dependent kinase II expression in rats.

Current studies have indicated that donepezil as a cholinesterase inhibitor can attenuate morphine-induced tolerance. The present study aimed to evaluate the possible role of N-methyl-d-aspartate receptors (NMDARs), protein kinase C (PKC) and CaM-dependent kinase II (CaMKII) pathways in this effect. Female Wistar rats received daily morphine (10 mg/kg, i.

Donepezil attenuates the development of morphine tolerance in rats with cancer-induced bone pain: The role of cortical N-methyl-D-aspartate receptors.

Cancer-induced bone pain (CIBP), which is associated with poor quality of life, is most commonly treated using opioids. However, long-term use of morphine for analgesia induces tolerance and can diminish the treatment's effectiveness. The mechanisms that underlie morphine tolerance have been reported to be related to the inflammation of the nervous system and hyperactivation of N-methyl-D-aspartate receptors (NMDARs).

Effects of anesthetic technique and surgery on myeloid-derived suppressor cells and prognosis in women who underwent breast cancer surgery: a prospective study.

Surgery and anesthesia-induced immunosuppression may play a critical role in tumor progression and metastasis. Myeloid-derived suppressor cells (MDSCs) are highly immunosuppressive myeloid cells, closely linked with tumor staging, clinical therapeutic efficacy and prognosis. This study aims to investigate the effect of anesthetic technique and surgery on the expression of MDSCs and prognosis in women who received breast cancer surgery.

Risk factors for anastomotic leakage following esophagectomy: Impact of thoracic epidural analgesia.

Background And Objectives: Anastomotic leakage (AL) is one of common complications after esophageal cancer surgery. Thoracic epidural analgesia (TEA) is often recommended in patients undergoing esophagectomy. However, the impact of TEA on AL is still controversial.

Is propofol injection pain really important to patients?

Background: Propofol injection pain (PIP) has been adequately studied during the past decades. However, patients' opinion on this problem and the incidence of patients' recall of this brief discomfort are still unknown. Thus, we conducted this study to know the patients' perspectives on PIP and provide useful information about the incidence of recall of PIP under our routine general anesthesia.
