CFTRinh-172 Patients with diabetes need frequent insulin injections or blood sampling to monitor blood glucose levels. The microneedles are a painless transdermal drug delivery system, which has great advantages in achieving self-management. There have been a lot of researches on microneedles used in diabetes treatment. Microneedle-based treatment of diabetes has also changed from a simple and reliable system to a complex and efficient system. This review introduces microfluidic, glucose response, and other contents based on microneedles, and some challenges in the development of microneedles.
Acyclovir is effective in treating herpes simplex virus infections of the central nervous system. The purpose of this study was to investigate the interactions between acyclovir and the efflux pumps P-glycoprotein (P-gp), breast cancer resistance protein (Bcrp), multidrug resistance protein 2 (Mrp2), and organic anion transporter 3 (Oat3) at the blood-brain barrier (BBB).
Acyclovir concentrations in the blood and brain were evaluated by microdialysis and high-performance liquid chromatography. Acyclovir pharmacokinetic parameters, including the area under the unbound blood concentration-time curve (AUC
), the area under the unbound brain concentration-time curve (AUC
), and the ratio of AUC
to AUC
(K
), were evaluated in the presence and absence of elacridar (P-gp/Bcrp inhibitor, 7.5 mg/kg), tariquidar (P-gp/Bcrp inhibitor, 7.5 mg/kg), MK571 (Mrp2 inhibitor, 7.5 mg/kg), cyclosporine (P-gp/Bcrp/Mrp2 inhibitor, 25 mg/kg), and probenecid (Oat3 inhibitor, 50 mg/kg).
The average AUC

LY01008 had been identified as being highly similar to the bevacizumab reference product in the pharmacy and pharmacology terms. The primary objective of this study was to compare the pharmacokinetic characteristics of the biosimilar candidate LY01008 with that of the bevacizumab (Avastin
) reference product after a single intravenous infusion in healthy Chinese adults. The secondary objective was to compare the safety and immunogenicity of LY01008 with those of bevacizumab.
In this double-blind, parallel-group, phase I study, 102 male subjects aged 18-45 years were randomized 11 to receive a single intravenous infusion of 3 mg/kg LY01008 or bevacizumab. Before the pivotal section, 12 healthy male subjects receiving a single intravenous (IV) infusion of 0.5 mg/kg or 1.5 mg/kg LY01008 were screened to verify the safety and tolerability of LY01008. Primary endpoints included the area under the concentration-time curve(AUC) from time zero to the last quantifiable time point (AUC
), AUC from time zero to th70191.
Clinical trial registration ID CTR20170191.This study observed the effects of treadmill running on adipose tissue browning and lipolysis in rats with induced heart failure and elucidated the possible mechanism. Rats underwent abdominal aortic constriction as a model of heart failure. Cardiac function was detected by echocardiography. We detected serum levels of norepinephrine and interleukin 6, cardiac atrial natriuretic peptide and brain natriuretic peptide and marker genes of browning, white adipose tissue (WAT), and lipolysis in adipose tissue. Rats with heart failure showed typical symptoms such as increased heart weight and mRNA levels of atrial natriuretic peptide and brain natriuretic peptide and decreased left ventricular ejection fraction. Exercise partially improved left ventricular diastolic function and significantly decreased atrial natriuretic peptide expression. Rats with heart failure showed significantly reduced body weight and ratios of muscle and fat weight to body weight. Exercise significantly increased body weight and the ratio of muscle weight to body weight. Heart failure stimulated the expression of proliferator-activated receptor-gamma coactivator-1-alpha and uncoupling protein 1 in epididymal WAT, inguinal WAT, and brown adipose tissue but decreased that of adiponectin and leptin in inguinal WAT. Lipolysis, characterized by high adipose triglyceride lipase and hormone-sensitive lipase expression, was activated in all adipose tissues. Exercise reduced browning and lipolysis in adipose tissues. Rats with heart failure had abnormally high levels of serum norepinephrine and interleukin 6, which could be suppressed by exercise. Exercise may improve cardiac cachexia and inhibit the browning and lipolysis of adipose tissue by downregulating sympathetic nervous system activity and inflammation.Actinic keratosis (AK) is the main risk factor for the development of cutaneous invasive squamous cell carcinoma (SCC). It represents the first sign of severe chronic ultraviolet radiation exposure, which has a clear significant effect. Nevertheless, the skin is exposed to many other exposome factors which should be thoroughly considered. Our aim was to assess the impact of exposome factors other than ultraviolet radiation (UVR) on the etiopathology of AK and Bowen's disease (BD) and progression of AK to SCC and to design tailored prevention strategies. We performed an exhaustive literature search in September 2021 through PubMed on the impact of exposome factors other than UVR on AK, BD and SCC. We conducted several parallel searches combining terms of the following topics AK, BD, SCC and microbiome, hormones, nutrition, alcohol, tobacco, viral infections, chemical contaminants and air pollution. Notably, skin microbiome studies have shown how Staphylococcus aureus infections are associated with AK and AK-to-SCC progression by the production of chronic inflammation. Nutritional studies have demonstrated how a caloric restriction in fat intake, oral nicotinamide and moderate consumption of wine significantly reduce the number of premalignant keratoses and SCC. Regarding lifestyle factors, both alcohol and smoking are associated with the development of SCC in a dose-dependent manner. Relevant environmental factors are viral infections and chemical contaminants. Human papillomavirus infections induce deregulation of cellular proliferation and are associated with AK, BD and SCC. In addition to outdoor jobs, occupations such as industrial processing and farming also increase the risk of developing keratoses and SCC. The exposome of AK will undoubtedly help the understanding of its etiopathology and possible progression to SCC and will serve as a basis to design tailored prevention strategies.
Most skin disorders, such as atopic dermatitis, psoriasis, skin cancer or age-related skin issues, are the result of a complex interaction between genetic and environmental factors over time. As an external organ, the skin provides the opportunity to study the link between exposure to the environment and several specific biological responses using an exposome approach. The aim of this review was to identify the state of the art of exposome approaches and elucidate the impact of the new era of exposomics on dermatology.
Two parallel and independent bibliometric analyses were conducted based on documents extracted from the Core Collection and the Science Citation Index Expanded (SCI-Expanded) databases from the Clarivate Analytics' Web of Science (WOS) platform by using the following search terms "exposome" and "skin exposome". In both searches, we used the topic field that includes title, abstract, author keywords and keywords plus terms and the following filters "English language" and all documents publisprevention strategies for patients suffering from these disorders.
Exposome studies are rapidly attracting interest in dermatology. The results of these studies will undoubtedly improve our understanding of why and under which circumstances some individuals develop skin disorders and help design tailored prevention strategies for patients suffering from these disorders.
Stress and sleep disturbance have been found to be associated with numerous adverse health outcomes, including cancer. Our study aimed to measure the association between quality of sleep, short-temperedness, and stress in life with the risk of thyroid cancer.
The present study is conducted on 361 newly diagnosed TC patients and 347 sex-age frequency matched controls. Control and case participants were registered with the same health centers. We used multiple logistic regression to investigate the association between TC risk and the interested factors.
Based on the results of the multivariate analysis, stress (OR
= 3.07, 95% CI 1.42-6.63) and short-temperedness (OR
= 2.00, 95% CI 1.28-3.11) were directly associated with the risk of TC. On the other hand having a quality sleep (OR
= 0.36, 95% CI 0.16-0.79) and quality sleep (OR
= 0.45, 95% CI 0.21-0.96, P = 0.041) seems to be a protective factor.
Some community-based interventions, e.g., lowering stress levels and improving sleep quality, may help in preventing different types of cancer, including TC. We suggest further evaluation of these important findings in the prevention of TC cancer.

The high mortality rate in severe cases of COVID-19 is mainly due to the strong upregulation of cytokines, called a cytokine storm. Hyperinflammation and multiple organ failure comprise the main clinical features of a cytokine storm. Nrf2 is a transcription factor which regulates the expression of genes involved in immune and inflammatory processes. Furthermore, Nrf2, as a master regulator, controls the activity of NF-κB which binds to the promoter of many pro-inflammatory genes inducible of various inflammatory factors. Inhibition of Nrf2 response was recently demonstrated in biopsies from patients with COVID-19, and Nrf2 agonists inhibited SARS-CoV-2 replication across cell lines in vitro. Glucosinolates and their hydrolysis products have excellent anti-inflammatory and antioxidant effects via the Nrf2 activation pathway, reduction in the NF-κB activation, and subsequent reduced cytokines levels.
Accordingly, these compounds can be helpful in combating the cytokine storm associated with COVID-19.
