Although nickel is found in the active sites of a class of superoxide dismutase (SOD), nickel complexes with non-peptidic ligands normally do not catalyze superoxide degradation, and none has displayed activity comparable to those of the best manganese-containing SOD mimics. Here, we find that nickel complexes with polydentate quinol-containing ligands can exhibit catalytic activity comparable to those of the most efficient manganese-containing SOD mimics. The nickel complexes retain a significant portion of their activity in phosphate buffer and under operando conditions and rely on ligand-centered redox processes for catalysis.

In almost all cancers, the p53 pathway is disabled and cancer cells survive. Hence, it is crucially important to induce cell death independent of p53 in the treatment of cancers. The transcription factor E2F1 is controlled by binding of the tumor suppressor pRB, and induces apoptosis by activating the gene, an upstream activator of p53, when deregulated from pRB by loss of pRB function.

Nearly a decade after the National Academy of Medicine released the "Improving Diagnosis in Health Care" report, diagnostic errors remain common, often leading to physical, psychological, emotional, and financial harm. Despite a robust body of research on potential solutions and next steps, the translation of these efforts to patient care has been limited. Improvement initiatives are still narrowly focused on selective themes such as diagnostic stewardship, preventing overdiagnosis, and enhancing clinical reasoning without comprehensively addressing vulnerable systems and processes surrounding diagnosis.

Article Synopsis
  • - E2F1 is a transcription factor that plays a dual role in cell growth, promoting both cell proliferation and tumor suppression, particularly when the tumor suppressor pRB is not functioning.
  • - The N-terminal region of E2F1 is crucial for activating tumor suppressor genes, as removing this region significantly reduces its ability to do so.
  • - GTF2H2, a general transcription factor, interacts with the N-terminal region of E2F1 and enhances its tumor suppressor gene activity, while its knockdown negatively impacts this function.

Background: Several strategies have been developed to detect diagnostic errors for organizational learning and improvement. However, few health care organizations (HCOs) have integrated these strategies into routine operations. To address this gap, the Agency for Healthcare Research and Quality released "Measure Dx: A Resource To Identify, Analyze, and Learn From Diagnostic Safety Events" in 2022.

During ageing, the extracellular matrix of the aortic wall becomes more rigid. In response, vascular smooth muscle cells (VSMCs) generate enhanced contractile forces. Our previous findings demonstrate that VSMC volume is enhanced in response to increased matrix rigidity, but our understanding of the mechanisms regulating this process remain incomplete.

Background: African American Women (AAW) are at high risk for stress-related cardiometabolic (CM) conditions including obesity, heart disease, and diabetes. Prior interventions lack attention to culturally-nuanced stress phenomena (Superwoman Schema [SWS], contextualized stress, and network stress), which are positively and significantly associated with unhealthy eating and sedentary behavior.

Purpose: The HARMONY Study is designed to test a culturally tailored mindfulness-based stress management intervention to address SWS, contextualized stress, and network stress as potential barriers to adherence to healthy exercise and eating goals.

Obesity is associated with chronic low-level inflammation and is known to contribute to metabolic dysfunction and hypogonadotropic hypogonadism, which we have previously termed the 'Reprometabolic Syndrome.' To investigate potential factors involved in obesity-related reproductive endocrine dysfunction, we conducted a secondary analysis of inflammatory markers in a sample of normal weight women exposed to a one-month eucaloric high-fat diet (HFD), which, as reported earlier, induced the relative hypogonadotropic hypogonadism characteristic of Reprometabolic Syndrome. Eighteen healthy women with a BMI between 18.
