Colorimetric fluorescence of the 1,10-phenantholineyl-imidazole sensor probe for the selective detection of Zn and Cd ions.

A colorimetric fluorescent probe, 4-(1H-imidazolo[4,5-f][1,10]phenanthroline-2-yl)-N, N-diphenylaniline (PIN), was designed, synthesized and characterized for the sensitive and selective detection of Zn and Cd. The color of the solution changed from blue to yellow visible to the naked eye with the addition of Zn and Cd. The probe PIN showed good anti-interference to Zn and Cd in the presence of a variety of metal ions, and the fluorescence intensity showed a good linear relationship with the concentrations of Zn and Cd, with detection limits of 34.

Thermal ablation for the treatment of malignant thyroid nodules: present and future.

As the utilization of high-resolution imaging modalities, such as ultrasound, becomes increasingly prevalent, there has been a swift rise in the detection rates of malignant thyroid nodules (MTC). Surgery remains the cornerstone of standard treatment for these nodules. However, the advent and evolution of thermal ablation (TA) techniques, encompassing radiofrequency ablation, laser ablation, and microwave ablation, have emerged as a novel therapeutic avenue for patients with MTC, particularly for those deemed unsuitable for surgery due to high risks or for those who refuse surgery.

Musculoskeletal Biomaterials: Stimulated and Synergized with Low Intensity Pulsed Ultrasound.

Clinical biophysical stimulating strategies, which have significant effects on improving the function of organs or treating diseases by causing the salutary response of body, have shown many advantages, such as non-invasiveness, few side effects, and controllable treatment process. As a critical technique for stimulation, the low intensity pulsed ultrasound (LIPUS) has been explored in regulating osteogenesis, which has presented great promise in bone repair by delivering a combined effect with biomaterials. This review summarizes the musculoskeletal biomaterials that can be synergized with LIPUS for enhanced biomedical application, including bone regeneration, spinal fusion, osteonecrosis/osteolysis, cartilage repair, and nerve regeneration.

Methods: Pubmed, Wed of Science, and APA PsycINFO were systematically searched for articles examining the association between chronic stress and HCC.

Results: Thirteen studies from five countries with 1,455 participants were included in the systematic review and nine studies were included in the meta-analysis.

Omega-3 polyunsaturated fatty acid biomarkers and risk of type 2 diabetes, cardiovascular disease, cancer, and mortality.

Background & Aims: Considerable attention has focused on the role of omega-3 polyunsaturated fatty acids (PUFA) in the prevention of cardiometabolic diseases, which has led to dietary recommendations to increase omega-3 fatty acid intake. A meta-analysis was conducted to summarize evidence from prospective studies regarding associations between omega-3 PUFA biomarkers and risk of developing major chronic diseases.

Methods: Four electronic databases were searched for articles from inception to March 1, 2022.

Shear wave elastography and pulsed doppler for breast lesions: Similar diagnostic performance and positively correlated stiffness and blood flow resistance.

Purpose: To compare the diagnostic performance of shear wave elastography (SWE) and pulsed Doppler ultrasound in breast lesions, and to explore whether the quantitative SWE parameters correlated with pulsed Doppler ultrasound parameters.

Materials And Methods: Seventy-nine patients with 79 breast lesions who had undergone conventional ultrasound, pulsed Doppler ultrasound and SWE examination were included. All of them underwent core needle biopsy or surgery within one week.

Levels and factors derived from the Health Action Process Approach of behavioral intentions to take up COVID-19 vaccination: A random population-based study.

Objectives: COVID-19 vaccination needs a high population coverage to achieve herd immunity. We investigated prevalence of three scenarios of intention of free COVID-19 vaccination involving: 1) 80% effectiveness and rare and mild side effects (Scenario 1), 2) 50% effectiveness and rare and mild side effect RMSE (Scenario 2), and 3) immediate vaccination (Scenario 3), and their associated factors derived from the pre-intentional motivational phase of the Health Action Process Approach (HAPA).

Methods: A random population-based telephone survey interviewed 450 Chinese adults in the general population (September 16-30, 2020).

Breast Elasticity Imaging Techniques: Comparison of Strain Elastography and Shear-Wave Elastography in the Same Population.

Our purpose was to compare the diagnostic performances of strain elastography (SE) and shear-wave elastography (SWE) in differentiating breast lesions by combining with conventional ultrasound (US). A total of 198 patients with 203 breast lesions underwent conventional US, SE and SWE examination using MyLab 90 and Aixplorer US systems. The SE parameters were SEscore, fat-to-lesion ratio, gland-to-lesion ratio, muscle-to-lesion ratio and SEmean, and the SWE parameters were Emax, Emean, Emin and Esd.

Higher Academic Stress Was Associated with Increased Risk of Overweight and Obesity among College Students in China.

This study examined associations between academic stress and overweight and obesity, and moderation effects of gender, grade, and types of college on such associations.
