Detection of biomarkers associated with physiological conditions provides critical insights into healthcare and disease management. However, challenges in sampling and analysis complicate the detection and quantification of protein biomarkers within the epidermal layer of the skin and in viscous liquid biopsy samples. Here, we present the "Lab-on-the-Needles" concept, utilizing a microneedle patch-based sensing box (MNP-based SenBox) for mobile healthcare applications.

The optimal concentration of remifentanil to provide adequate antinociception and stable hemodynamics during skull pin fixation under analgesia nociception index monitoring is unknown. This study is to assess the 90% effective concentration of remifentanil for skull pin fixation under hemodynamic and analgesia nociception index monitoring.
View Article and Find Full Text PDFTriple-negative breast cancer (TNBC) represents a formidable challenge due to the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression, rendering it unresponsive to conventional hormonal and targeted therapies. This study introduces the development of mesoporous nanoreactors (NRs), specifically mPDA@CuO NRs, as acid-triggered agents capable of self-supplying HO for chemodynamic therapy (CDT). To enhance therapeutic efficacy, these NRs were further modified with immune checkpoint antagonists, specifically anti-PD-L1 and anti-CD24 antibodies, resulting in the formation of dual antibody-aided mesoporous nanoreactors (dAb-mPDA@CuO NRs).

Regorafenib, a multi-kinase inhibitor, has shown promise in HCC treatment; however, its efficacy can be enhanced by combining it with other agents. 18β-glycyrrhetinic acid (18β-gly) is a natural compound with potential anti-cancer properties.

Materials And Methods: The SAS-bearing xenograft model evaluated imipramine's impact on tumor growth.
Background: Scheduling patient appointments in hospitals is complicated due to various types of patient examinations, different departments and physicians accessed, and different body parts affected.
Objective: This study focuses on the radiology scheduling problem, which involves multiple radiological technologists in multiple examination rooms, and then proposes a prototype system of computer-aided appointment scheduling based on information such as the examining radiological technologists, examination departments, the patient's body parts being examined, the patient's gender, and the patient's age.
Methods: The system incorporated a stepwise multiple regression analysis (SMRA) model to predict the number of examination images and then used the K-Means clustering with a decision tree classification model to classify the patient's examination time within an appropriate time interval.
Background: Clinical management of COVID-19 requires close monitoring of lung function. While computed tomography (CT) offers ideal way to identify the phenotypes, it cannot monitor the patient response to therapeutic interventions. We present a case of ventilation management for a COVID-19 patient where electrical impedance tomography (EIT) was used to personalize care.

Loss of PTEN expression and hyperactivation of Akt can result in tumorigenesis. Previous studies observed expression of the Akt protein and absence of the PTEN protein in bladder cancer and non-small cell lung carcinoma tissues.

Current strategies for GSH detection often require sophisticated instruments that may not be available in laboratories with fewer resources. Here, we circumvent this problem by introducing a lateral flow plasmonic biosensor (LFPB) based on gold-viral biomineralized nanoclusters (AuVCs) as nanozymes that enables the detection of a few molecules with the naked eye and quantified by an auto-analysis software.

The purpose of this study was to develop a mobile healthcare (mHealth) system using a drop of blood, which comprised a lateral flow pad (LFP), mesoporous Prussian blue nanoparticles (MPBs) as artificial nanozymes and auto-calculation software for on-site determination of UA in blood and data management. A standard curve was found to be linear in the range of 1.

There is a great need for a simple and fast point-of-care (POC) test for early diagnosis and amelioration in the survival rate. We present a POC test comprising a new vial-immunosensor, nanoenzyme, and iPhone 7 plus, which detects and quantifies the new biomarker FXYD domain-containing ion transport regulator 3 (FXYD3) in human urine for specific UC screening, tumor-grade classification, and postoperative monitoring by the grayscale value of the photograph taken.
View Article and Find Full Text PDFZika virus (ZIKV) is a mosquito-borne flavivirus (FLAV) that emerged in Brazil in 2015 and has rapidly spread to more than 50 countries worldwide. However, early, accurate, and specific point-of-care (POC) diagnosis of ZIKV is very difficult because most infected patients are asymptomatic or display nonspecific symptoms similar to those of other viral infections, and most of the analysis also requires instruments. Herein, an instrument-free ZIKV POC test using a drop of blood comprising a vial immunosensor, artificial nanozyme platinum/gold core-shell nanoparticles (Pt@Au NPs) as a signal probe, and a smartphone was developed to specifically detect ZIKV without cross-reaction with other FLAVs.

In the case of MO, the reaction rate of MGNRs showed approximately 45.6-fold and 1520.

The ultrasensitive immunosensor was constructed using an ApoA1 antibody (Ab)-functionalized chip (biochip) and self-linkable peroxidase-mimicking, PB-incorporated magnetic graphene oxide (PMGO). After incubating the sample and capturing ApoA1 proteins captured on the biochip, the PMGO was functionalized with Ab, and then mouse IgG (PMGO-1), rabbit anti-mouse IgG antibody (PMGO-2), and goat anti-rabbit IgG antibody (PMGO-3) were added together.

However, we do not know what the most stable configuration of the selected aptamer bound with target protein is. Therefore, a systematic search process using the stochastic tunneling-basin hopping (STUN-BH) method is proposed to find the most stable configuration of the ssDNA aptamer specific for vascular endothelial growth factor (VEGF) capture (Apt; 5'-TGTGGGGGTGGACGGGCCGGGTAGA-3').

Although chRCC generally demonstrates more favorable outcomes compared with other subtypes of RCC, there is a 6-7% probability of tumor progression and metastasis in this disease. The subclassification of a more aggressive subtype of chRCC may be useful for the management of this cancer.

These cantharidinimine derivatives were tested for their capabilities to suppress growth of the human carcinoma cell lines, HL-60, MCF7, Neuro-2a and A549, because the incidence rate is more prominent in Asian countries than western countries. Compounds 3c-d and 6h-i were found to have some antitumor activity in HL-60 but less activity in MCF cell and compounds 8j-l displayed some inhibition effects to A549 cell line, but less effect to Neuro-2a cell line.
