The coronavirus disease 2019 pandemic substantially impacted the delivery of cancer services and programs. Here we reviewed and synthesized the global scale and impact of pandemic-related delays and disruptions on cancer services, including diagnosis, diagnostic procedures, screening, treatment and supportive and palliative care. Based on data from 245 articles in 46 countries, we observed declines in the number of cancer screening participation (39.0%), diagnoses (23.0%), diagnostic procedures (24.0%) and treatment (28.0%), ranging from a 15.0% decline for radiotherapy to a 35.0% decline for systemic treatment during the pandemic compared to during the prepandemic period. Medium-human development index (HDI) category countries experienced greater reductions than high- and very-high-HDI countries. Missing data from low-HDI countries emphasize the need for increased investments in cancer surveillance and research in these settings. PROSPERO registration: CRD42022301816.

The widespread application of quantum dots (QDs) in recent years has raised concerns about potential environmental and human health risks. Although the toxicity of cadmium telluride quantum dots (CdTe QDs) has been partially studied, their effects on stem cells, tissue regeneration, neurodevelopment, and neurobehavioral toxicity remain unclear. This study aimed to investigate the combined toxic effects and mechanisms of CdTe QDs on planarians at the individual, tissue, cellular, and molecular levels.

Arrhythmias are a hallmark of myocardial infarction (MI) and increase patient mortality. How insult to the cardiac conduction system causes arrhythmias following MI is poorly understood. Here, we demonstrate conduction system restoration during neonatal mouse heart regeneration versus pathological remodeling at non-regenerative stages.

Translationally controlled tumor protein (TCTP) is a well conserved and ubiquitously expressed multifunctional protein found in many organisms and is involved in many pathophysiological processes like cell proliferation, differentiation, development and cell death. The role of TCTP in anti-apoptosis and cancer metastasis makes it a promising candidate for cancer therapy. Dictyostelium discoideum, a protist, has two isoforms (TCTP1 and TCTP2, now referred to as TPT1 and TPT2) of which we have earlier elucidated TPT1.

Background: Primary cilia are solitary membrane-bound organelles emanating from the apical surface of most mammalian cells. They serve as sensory organelles sampling the extracellular environment and reprogramming the transcriptional machinery in response to changes in fluid flow. Ciliopathies, a group of genetic disorders characterized by disrupted cilia structure and/or function, share common phenotypes such as vascular dysfunction and cognitive impairment.

Background: When performing a picture description task, healthy individuals tend to look only briefly at a target before beginning its description, after which they move promptly onto the next target. This sequence may be disrupted in those with cognitive impairment. Just as cognitively impaired individuals produce greater numbers of disfluencies and pauses, those with mild cognitive impairment (MCI) may delay speech production by extending their gaze behavior towards a target before beginning its description.
