Abstract Aging is associated with increased oxidative stress in vascular endothelial and smooth muscle cells, which contribute to the development of a wide range of diseases affecting the circulatory system in older adults. There is growing evidence that in addition to increased production of reactive oxygen species (ROS), aging critically impairs pathways determining cellular resilience to oxidative stressors. In young organisms, the evolutionarily conserved nuclear factor-erythroid-2-related...

SUMMARY The mid‐infrared (IR) spectra of human cystic fibrosis (CF) cells acquired by Fourier transform infrared microspectroscopy (microFTIR) were compared to those of non‐CF cells. Within the 1700‐1480cm‐1 spectral domain of amides, unsupervised explorative principal component analysis identified a few variables reflecting quantitative and qualitative vibrations arising from protein secondary structures and amino acid side chains. Their pattern reflected α‐helix to β‐sheet transitions in bronchial...

Abstract Irradiation of femtosecond (fs) pulse lasers in the visible and near‐infrared ranges have been proposed as a promising candidate for inactivating viruses. However, in order to achieve significant virus inactivation, past works have required relatively long irradiation times (1 hour or longer), even for small volumes. Given its advantages compared with other techniques, there is an urgent need to shorten the time required to inactivate viruses using fs laser technology. In this study, we...

Abstract Advance care planning (ACP) has been identified as a fundamental part of every patient’s total health care plan and is actively supported by a number of health care organizations. Despite these endorsements, however, having advance care planning conversations has not come easily for physicians. Training future physicians should include practical ways to address this issue. Fifty physicians at an oncology hospital, who were identified as having the most ACP conversations,...

Abstract In 2013, the US Preventive Services Task Force recommended low-dose computed tomography screening for smokers at high risk of lung cancer; however, use remains low. Efforts to promote lung cancer screening need to consider how receptive this population is to preventive healthcare and cancer screening. In addition, because of demonstrated heterogeneity in behaviors by smoking status, interventions may need to differ among eligible high-risk subgroups. To assess the engagement...

Improving the extremely low temperature operation of rechargeable batteries is vital to the operation of electronics in extreme environments, where systems capable of high‐rate discharge are in short supply. Herein, we demonstrate the holistic design of dual‐graphite batteries, which circumvent the sluggish ion desolvation process found in typical lithium‐ion batteries during discharge. These batteries were enabled by a novel electrolyte, which simultaneously provided high electrochemical stability...

Palladium‐catalyzed alkene‐directed cross‐coupling of aryl iodide with another aryl halide through C−H arylation opens a unique avenue for unsymmetrical biaryl‐derived molecules. However, homo‐coupling of aryl iodides often eroded the overall synthetic efficiency. Reported herein is a highly chemoselective Pd(0)‐catalyzed alkyne‐directed cross‐coupling of aryl iodides with bromophenols, which was subsequently followed by phenol dearomatization to furnish a very attractive [2+2+1] spiroannulation....

It is highly desirable to optimize the structure of photocatalysts at the atomic scale to facilitate the separation of electron‐hole pairs for enhanced performance, but it still remains challenging. Here, we report a highly efficient photocatalyst by assembling single Pt atoms on defective TiO 2 support (Pt 1 /def‐TiO 2 ). Except as proton reduction sites, single Pt atoms promote the neighboring TiO 2 units to generate surface oxygen vacancies and form Pt‐O‐Ti 3+ atomic interface. Experimental...

The aromatic nitrogen atoms of heteroarylaldehydes are activated by carbene catalysts to react with ketone electrophiles. Multi‐functionalized cyclic N,O‐acetal products are afforded in generally good to excellent yields and optical purities. Our reaction involves the formation of an unprecedented aza‐fulvene typed acylazolium intermediate. A broad range of N‐heteroaromatic aldehydes and electron‐deficient ketone substrates work effectively in this transformation. Several of the chiral N,O‐acetal...

A stereodivergent reductive coupling reaction between allylic carbonates and vinyl triflates to furnish both ( E )‐ and ( Z )‐1,4‐dienes has been achieved via visible‐light‐induced photoredox/nickel dual catalysis. The mild conditions allow for good compatibility of both vinyl triflates and allylic carbonates. Notably, the stereoselectivity of this synergistic cross‐electrophile coupling can be tuned by an appropriate photocatalyst with a suitable triplet state energy, providing a practice and...
