Psychosocial Correlates of Death Anxiety in Advanced Cancer: A Scoping Review.

Objectives: Individuals living with advanced cancer commonly experience death anxiety, which refers to the distressing thoughts or feelings associated with awareness of one's mortality. Deriving an overview of existing literature on the psychological and social factors linked to death anxiety may inform conceptual models, clinical screening, and intervention strategies in oncology and palliative care. Therefore, the present scoping review was conducted to summarize the current literature on the psychosocial correlates of death anxiety among individuals with advanced cancer.

Passive accumulation of alkaloids in inconspicuously colored frogs refines the evolutionary paradigm of acquired chemical defenses.

Understanding the origins of novel, complex phenotypes is a major goal in evolutionary biology. Poison frogs of the family Dendrobatidae have evolved the novel ability to acquire alkaloids from their diet for chemical defense at least three times. However, taxon sampling for alkaloids has been biased towards colorful species, without similar attention paid to inconspicuous ones that are often assumed to be undefended.

Revisiting hydrogen peroxide as radiosensitizer for solid tumor cells.

Background And Purpose: Tumor hypoxia is the principal cause of clinical radioresistance. Despite its established role as radiosensitizer, hydrogen peroxide (HO) encounters clinical limitations due to stability and toxicity concerns. Recent advancements in drug delivery combine HO with sodium hyaluronate (SH), enabling intratumoral administration of HO.

Calmodulin binding is required for calcium mediated TRPA1 desensitization.

Calcium (Ca) ions affect nearly all aspects of biology. Excessive Ca entry is cytotoxic and Ca-mobilizing receptors have evolved diverse mechanisms for tight regulation that often include Calmodulin (CaM). TRPA1, an essential Ca-permeable ion channel involved in pain signaling and inflammation, exhibits complex Ca regulation with initial channel potentiation followed by rapid desensitization.

"We do it all": A qualitative exploration of the caregiver role for young adults with cerebral palsy.

Aim: To describe the complex roles of and crucial support provided by caregivers to young adults with cerebral palsy (CP) during the transition to adulthood.

Method: This was a qualitative study. We conducted 20 semi-structured interviews (13 caregiver; 7 patient/caregiver dyad) and analyzed data using a qualitative descriptive approach informed by phenomenological principles.
