Q & A: Educating children about health risks of vaping
The number of teens who use electronic cigarettes, or vape, is at an all-time high, and there ’s growing concern that vaping can cause severe lung illness and injury, as well as an addiction to nicotine.Additionally, several deaths have been attributed to vaping-related illnesses, and that number continues to grow, according to the Centers for Disease Control and Prevention. Recent CDC data also shows that 1 in 4 high school students vape, and that e-cigarette use among middle school students is on the rise.UCLA pediatric pulmonologistDr. Eric Hamberger explains how vaping affects children ’s health, and how parents can keep their kids safe and informed about the dangers of e-cigarettes.How do e-cigarettes work?E-cigarettes are battery-powered devices that carry nicotine fluid and, sometimes, other potentially harmful ingredients. When heated, the fluid becomes an aerosol consisting of fine particles, which is then inhaled into the lungs. Most e-cigarettes do not look like traditional cigarettes. They come in many forms and can look like everyday products like pens, USB flash drives, phones and tubes of lipstick. This can make vaping easy to conceal.How can parents tell if a child is vaping?The most common effects are changes in behavior, including irritability, interrupted sleep, difficulty concentrating and mood swings. You may also see physical changes, such as increased thirst, dry cough, caffeine sensitivity, nose bleeds and exercise intolerance.You may also ...

CONCLUSIONS: The introduction of spacer sequence between chelator and BBN(7-14) led to improved bidistribution. Analogue with tri-Gly spacer is the more promising radiopeptide for targeting GRP receptor than Ser conjugate. Therefore, these analogs can be considered as a candidate for the identification of bombesin-positive tumors. PMID: 32497000 [PubMed - as supplied by publisher]
Conclusion: Worst indicators among women receiving BF reflect social inequalities inherent in this most vulnerable group. The study also shows that BF is being targeted at the most vulnerabl e women.
Resumo O artigo apresenta resultados da pesquisa de opini ão realizada no Brasil sobre a percepção do isolamento social durante a pandemia de COVID-19. O questionário foi elaborado no Google Forms, disseminado por redes sociais, com questões sobre o perfil socioeconômico e fatores associados ao isolamento. Obteve-se uma amostra com 16.440 respondente s. Os dados foram analisados no software Stata 13. O convívio social foi o aspecto mais afetado entre pessoas com maior escolaridade e renda 45,8%, para pessoas de baixas renda e escolaridade, problemas financeiros provocam maior...
Authors: Ao H, Li Y, Li H, Wang Y, Han M, Guo Y, Shi R, Yue F, Wang X Abstract Hydroxy genkwanin (HGK), a flavonoid compound from natural resources, showed good inhibition against the growth of breast tumor cells. However, the poor solubility restricted the further study and the in vivo drug delivery of HGK. We prepared HGK nanosuspensions by antisolvent precipitation method and investigated their characterization, stability, hemolysis probability, release behavior in vitro, antitumor activity in vitro and in vivo, and preliminary safety through acute toxicity experiments. The resultant HGK nano...
Authors: Zhang X, Ren X, Tang J, Wang J, Zhang X, He P, Yao C, Bian W, Sun L Abstract Multidrug resistance (MDR) of cancer cells is a significant challenge in chemotherapy, highlighting the urgent medical need for simple and reproducible strategies to reverse this process. Here, we report the development of an active tumor-targeting and redox-responsive nanoplatform (PA-ss-NP) using hyaluronic acid-g-cystamine dihydrochloride-poly-ε-(benzyloxycarbonyl)-L-lysine (HA-ss-PLLZ) to co-deliver paclitaxel (PTX) and apatinib (APA) for effective reversal of MDR. This smart nanoplatform specifically bound to CD44 rec...
