Structural Transformation and Degradation of Cu Oxide Nanocatalysts during Electrochemical CO Reduction.

The electrochemical CO reduction reaction (CORR) holds enormous potential as a carbon-neutral route to the sustainable production of fuels and platform chemicals. The durability for long-term operation is currently inadequate for commercialization, however, and the underlying deactivation process remains elusive. A fundamental understanding of the degradation mechanism of electrocatalysts, which can dictate the overall device performance, is needed.

The effects of mindfulness-focused mental performance coaching on a general surgery residency program.

Background: Burnout is a proven challenge in surgeons and surgical trainees, associated with higher rates of attrition compared to other medical specialties. Here we report the impact of a mental performance coaching program as it relates to surgery trainee wellbeing.

Methods: A mixed-format mental performance coaching program was implemented at a large academic medical center's general surgery residency over a single academic year.

CAR expression in invasive breast carcinoma and its effect on adenovirus transduction efficiency.

Background: Breast cancer is the second leading cause of death in women, with invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) as the two most common forms of invasive breast cancer. While estrogen receptor positive (ER+) IDC and ILC are treated similarly, the multifocality of ILC presents challenges in detection and treatment, worsening long-term clinical outcomes in patients. With increasing documentation of chemoresistance in ILC, additional treatment options are needed.

A Quantitative Evaluation of the Effects of Radiation Therapy on the Post-Surgical Breast.

Background: Radiation (RT) effects on breast volume may impact breast-conserving therapy (BCT) outcomes, but quantitative information is lacking regarding the extent/timing of volume loss. This study aimed to quantify volume loss by assessing changes in irradiated breasts.

Methods: Breast volume changes were calculated for 113 patients (115 breasts) following T1 tumor lumpectomies.

Paravertebral versus Pectoralis-II (Interpectoral and Pectoserratus) Nerve Blocks for Postoperative Analgesia after Nonmastectomy Breast Surgery: A Randomized, Controlled, Observer-masked Noninferiority Trial.

Background: Pectoralis-II and paravertebral nerve blocks are both used to treat pain after breast surgery. Most previous studies involving mastectomy identified little difference of significance between the two approaches. Whether this is also accurate for nonmastectomy procedures remains unknown.
