Meanwhile, with FN-mediated targeting, the DOX-TAF@FN platform can specifically target tumor cells with high expression of αvβ3 integrin. Finally, the TAF network also enables the DOX-TAF@FN to have an r1 relaxivity of 6.1 mM-1 s-1 for T1-weighted MR imaging of tumors. The developed DOX-TAF@FN nanocomplexes may represent an updated multifunctional nanosystem with simple compositions for cooperative MR imaging-guided targeted chemo-/chemodynamic/immune therapy of tumors.Looking for high-performance substrates is an important goal of current surface enhanced Raman scattering (SERS) research. Herein, ultrathin multilayer rhenium (Re) nanosheets as a rare-earth metal substrate are found to have extraordinary SERS performance. These Re nanosheets are prepared through a convenient low-temperature molten salt strategy, and their total thickness is ∼5 nm, including 3-4 layers of ultrathin nanosheets with a thickness of only ∼1 nm. The viscosity of molten salt plays a key role in the formation of these ultrathin layered nanosheets. These nanosheets exhibit a strong and well-defined localized surface plasmon resonance (SPR) effect in the visible light region. The plasmonic Re nanosheets show excellent SERS performance with high sensitivity, chemical stability, and signal repeatability. The lowest detection limit for toxic compounds is 10-12 mol, and the corresponding Raman enhancement factor is 9.1 × 108. A composite enhancement mechanism caused by localized-SPR and charge transport has played an important role in the rare-earth-SERS. High-throughput multiassay analysis is performed on the flexible membrane assembled from the Re nanosheets, which highlights that our system is capable of rapid separation and identification of the samples containing various analytes.Gas-phase synthesized binary nanoparticles (NPs) possess ultraclean surfaces, which benefit versatile uses in sensors and catalysts. However, precise control of their configuration and properties is still a big challenge because the growth mechanism and phase evolution dynamics in these NPs are very hard to unveil. Here, we report a strategy to investigate the phase evolution dynamics in binary NPs by using e-beam assisted ultrafast local heating and cooling inside a transmission electron microscope. With this strategy, the phase segregation and corresponding shape evolution of PbBi NPs are in situ revealed. It is found that the as-prepared PbBi alloy NPs will transform into heterostructures under e-beam stimulated structural relaxation, leading to the formation of featured Janus configurations with faceted Bi polyhedron parts and intermetallic hemisphere parts. During phase segregation, Pb1Bi1 and Pb7Bi3 phases are captured and identified, and a model of phase and shape evolution of PbBi nanoalloys is developed and contrasted with that of their bulk counterparts. These findings benefit the understanding of the phase dynamics of binary NPs and can provide in-depth information for engineering their structures for practical applications.Activities of catalase (CAT) and superoxide dismutase (SOD) of ceria nanoparticles (CeO2 NPs) provide the possibility for their application in nervous system oxidative stress diseases including Alzheimer's disease (AD). The addition of hot electrons produced by a plasma photothermal effect can expand the photocatalytic activity of CeO2 to the near-infrared region (NIR), significantly improving its redox performance. Therefore, we coated both ends of gold nanorods (Au NRs) with CeO2 NPs, and photocatalysis and photothermal therapy in the NIR are introduced into the treatment of AD. Fasudil molecular weight Meanwhile, the spatially separate structure enhances the catalytic performance and photothermal conversion efficiency. In addition, the photothermal effect significantly improves the permeability of the blood-brain barrier (BBB) and overcomes the shortcomings of traditional anti-AD drugs. To further improve the therapeutic efficiency, Aβ-targeted inhibitory peptides were modified on the middle surface of gold nanorods to synthesize KLVFF@Au-CeO2 (K-CAC) nanocomposites. We have verified their biocompatibility and therapeutic effectiveness at multiple levels in vitro and in vivo, which have a profound impact on the research and clinical transformation of nanotechnology in AD therapy.
In Mexico 130,000 people live with chronic kidney disease (CKD). Heart conditions are the most frequent clinical problems; 45% of the deaths of patients in replacement therapy have a cardiac origin.
To identify the probability of presenting acute heart failure (AHF) in patients with CKD in the Adult Emergency Department (AED) of a second-level hospital.
Case-control study with 111 cases and 103 controls. Cases were defined as patients with CKD admitted to AED for AHF compared with controls patients with CKD who were admitted for a different diagnosis. Binary logistic regression was performed and odds ratio (OR) and 95% confidence intervals (95% CI) were determined. A value of p ˂ 0.05 was considered significant.
Arterial hypertension (OR 7.12, 95% CI 2.3-22.06, p = 0.01), the use of 3 or more antihypertensive drugs (OR 2.903, 95% CI 1.19-7.11, p = 0.02), the use of inhibitors of angiotensin converting enzyme (ACE inhibitors) (OR 4.25, 95% CI 1.78-10.09, p = 0.01), angiotensin II receptor blockers (ARBs) (OR 2.41, 95% CI 1.19-4.89, p = 0.014), diuretics (OR 42.87, 95% CI 9.02-203.63, p = 0.00), peritoneal dialysis (OR 2.48, 95% CI 1.25-4.81, p = 0.009) and hemodialysis (OR 0.40, 95% CI 0.20-0.79, p = 0.009) had statistical significance.
CKD patients with arterial hypertension, use of ACE inhibitors, ARBs, diuretics and peritoneal dialysis were more likely to present AHF, while patients who were on hemodialysis were less likely to presenting it.

The relationship of anthropometric and body composition indicators with the evolution of kidney disease in patients with type 2 diabetes, is still inconsistent.
To identify the association of indicators of kidney disease with indicators of metabolic and anthropometric control in patients with type 2 diabetes.
An analytical cross-sectional study was carried out in 395 patients of the first level of care. The glucose, glycosylated hemoglobin (HbA1c), creatinine and lipid profile were measured. The kidney disease (CKD) was made when urinary albumin excretion (UAE) > 30 mg/g and with a reduction in the level of glomerular filtration rate < 60 mL/min/1.73 m2, using the CKD-formula. Weight and waist circumference were measured, as well as the body composition through bioimpedance.
Seventeen percent of the population has a diagnosed with CKD with alteration of the UAE and 6.6% had a reduced GFR. A longer time of diagnosis of the diabetes, higher HbA1c level and body fat were associated with an UAE > 30 mg/g, (p < 0.05). The decline in GFR (< 60 mL/min/1.73 m2) was associated with older age, being a woman, greater waist circumference, and a higher percentage of body fat (p < 0.05).
A higher level of waist circumference and a lower percentage of body fat are associated with a greater evolution of chronic kidney disease in patients with type 2 diabetes. Glycemic uncontrol is identified in patients with high urinary albumin excretion.

As the global incidence of end-stage organ failure increases, the gap between organ donors and recipients continues to widen. This study was conducted to determine the association between organ donation awareness and organ donation willingness among students of a Saudi university.
This analytical cross-sectional study was conducted in King Faisal University, Al-Ahsa, Saudi Arabia. Multi-stage stratified random sampling was used to select the required 723 sample size. Estimation of proportion of students who were aware about organ donation and those who were willing to donate their organs was performed using EpiInfo© Version 7. Association between organ donation awareness and willingness was determined using multivariate logistic regression.
Nearly 98% of the participants were aware that organ donation saves lives (95% CI 96.27%-98.53%); 84.09% were aware that Islam allows organ donation (95% CI 81.25%-86.58%); 64.87% were aware that organ donation is successfully done in Saudi Arabia (95% CI 61.32%-68.26%); 32.64% were aware that the government gives incentives to the family of an organ donor (95% CI 29.32%-36.14%). Over half (56.71%) of the students (95% CI 53.07 - 60.28%) expressed willingness to donate their organs. Positive association was found between awareness on the position of Islam on organ donation (OR=2.7023, p<0.0001) and awareness of that organ donation can be successfully performed in Saudi Arabia (OR=1.9447, p=0.0001).
Awareness that Islam allows organ donation and awareness that organ donation is successfully done in Saudi Arabia increased the students' willingness to donate.

Atopic dermatitis (AD) is a disease with an impact on the patient's quality of life (QoL). Several tools have been designed to assess the clinical severity of the disease, such as the Eczema Area and Severity Index (EASI), while specific instruments have been created to assess QoL, such as the Dermatology Life Quality Index (DLQI) and the Quality of Life Index for Atopic Dermatitis (QoLIAD).
To define which tool is the best to assess the QoL condition of adult patients with AD in relation to the EASI.
Patients with AD (> 18 years old) were selected who agreed to complete the DLQI and QoLIAD questionnaires, as well as to have a dermatologic examination reported according to the EASI. Three simple linear regression models were fitted in order to quantify the association between EASI with DLQI and QoLIAD. A value of p < 0.05 was considered statistically significant. The CV condition model with the highest pseudo R2 value was considered to have the strongest association with EASI.
A total of 72 patients were included. Simple quantile regression models revealed a regression coefficient of 0.243 for DLQI (p = 0.002) and 0.252 for QoLIAD (p = 0.003). The pseudo R2 values were 0.15 for DLQI and 0.10 for QoLIAD, so DLQI had a higher correlation with EASI.
DLQI proved to be the best instrument to assess CV impairment in adult patients with AD.

Since December 2019, there has been a global outbreak of COVID-19. As of the end of July 2020, more than 600,000 deaths had been reported globally. The purpose of this paper is to further explore the application of non-invasive ventilation in severe COVID-19 patients.
A retrospective study was conducted to included 57 confirmed COVID-19 patients, among which 36 cases were severe. According to different oxygen inhalation methods, they were divided into non-invasive ventilator assisted ventilation group with 21 cases (group A) and 15 cases of nasal catheter oxygen inhalation group (group B). The data of respiration (RR), heart rate (HR), partial arterial pressure of oxygen (PaO2), partial arterial pressure of carbon dioxide (PaCO2), and oxygenation index (OI) before the treatment of noninvasive ventilator assisted ventilation or nasal catheter oxygen treatment at 24, 48, and 72 hours of treatment of the 2 groups were collected and analyzed to determine whether the above indicators were statistically different in each time period.
