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.

Distressing Aspects of Elder Abuse Victimization: Perspective of Survivors.

Objectives: Our understanding of elder abuse (EA) phenomena has largely been shaped from the perspective of researchers and professionals whose conceptualizations often differ from the perceptions of older adults who experience mistreatment. This study sought to understand the most distressing aspects of EA victimization from the perspective of survivors.

Methods: Using a descriptive phenomenological approach, individual interviews were conducted with a diverse sample ( = 32) of EA survivors, recruited from EA support and Adult Protective Services programs in New York City and Los Angeles.

ALKBH1: emerging biomarker and therapeutic target for cancer treatment.

As neoplastic cells proliferate, disseminate, and infiltrate, they undergo substantial alterations in their epigenetic configuration. Among the pivotal enzymes implicated in this phenomenon is the AlkB family of demethylases, notably AlkB homolog 1 (ALKBH1), which demonstrates conspicuous upregulation across various malignancies. The heightened expression of ALKBH1 renders it a compelling candidate for the development of multifaceted anticancer modalities.

COEPA ready: Innovative pedagogy for integrating social determinants of health in PharmD curricula.

Background: The American Association of Colleges of Pharmacy Curriculum Outcomes and Entrustable Professional Activities (COEPA) recognize the need for social determinants of health (SDH) education for pharmacy learners. However, there is a dearth of published strategies for incorporating comprehensive SDH education in Doctor of Pharmacy curricula. The objectives of this study were to: 1) highlight unpublished exemplars of SDH teaching models and 2) propose strategies for teaching SDH.

Non‑coding RNA‑mediated epigenetic modification of ferroptosis in non‑small cell lung cancer (Review).

Ferroptosis is a novel form of regulated cell death that plays a key role in inhibiting tumor malignancy. The ferroptosis signalling cascade provides new opportunities for lung cancer therapy. Non‑coding RNA (ncRNA)‑mediated epigenetic modification can influence the vulnerability of cancer cells to ferroptosis in non‑small‑cell lung cancer (NSCLC).

Intracranial Nanogel Pellets Carrying Temozolomide and Paclitaxel for Adjuvant Brain Cancer Therapy.

Glioblastoma multiforme is the most frequently diagnosed primary malignant brain tumor. Despite multimodal therapy with surgical resection, radiation therapy, and chemotherapy, recurrence of the tumor is almost always guaranteed due to the infiltrative nature of the disease. Moreover, the blood brain barrier imparts an additional layer of complexity by impeding the delivery of therapeutic agents to the tumor, hence limiting the efficacy of systemically delivered drugs.

Cancer nuclear envelope rupture and repair in taxane resistance.

Taxanes, including paclitaxel, docetaxel, and cabazitaxel, are key agents in cancer treatment, often used as front-line chemotherapy drugs in combination with other agent(s) (commonly carboplatin) and as second-line treatments alone. Generally, taxanes are highly effective, but drug resistance unavoidably develops following repeated treatment. Taxanes work by binding to and stabilizing microtubules, leading to mitotic arrest, mitotic catastrophe, and micronucleation.

Hypothermia as a Presenting Sign of Venlafaxine-Induced Neonatal Abstinence Syndrome in 2 Neonates.

Maternal antidepressant use has increased during the past 2 decades, with venlafaxine emerging as a common agent during pregnancy. Both venlafaxine and its active metabolite possess prolonged half-lives in adults; however, abrupt discontinuation may lead to withdrawal including irritability, jitteriness, lethargy, restlessness, and insomnia. The drug and its metabolite readily cross the placenta, posing additional considerations during pregnancy.

Targeting ferroptosis offers therapy choice in sepsis-associated acute lung injury.

Sepsis-associated acute lung injury (SALI) is a common complication of sepsis, consisting of a dysfunctional host response to infection-mediated heterogenous complexes. SALI is reported in up to 50 % of patients with sepsis and causes poor outcomes. Despite high incidence, there is a lack of understanding in its pathogenesis and optimal treatment.

Radio Frequency Ablation of Enlarged Thyroid Nodules: A Case Report.

In the thyroid, abnormal growth can be the result of either benign thyroid nodules (BTNs) or differentiated thyroid cancers (DTCs). If the growth is confirmed to be a DTC, surgical intervention, either a partial or total thyroidectomy, is recommended. Although a majority of BTNs do not require treatment, intervention becomes necessary when nodules cause symptoms, enlargement, or a rare suspicion of malignancy.

Evidence of Commonly Used Integrative Approaches with Pharmacotherapy for Chronic Pain Management.

This review examines the integration of traditional pharmacological methods with alternative and complementary therapies in chronic pain management. It delves into neurostimulation techniques, highlighting their clinical outcomes and biological bases. Acupuncture's role in modulating pain pathways is explored, illustrating its balance of tradition and clinical application.

Post-translational modifications in drug resistance.

Resistance to antitumor drugs, antimicrobial drugs, and antiviral drugs severely limits treatment effectiveness and cure rate of diseases. Protein post-translational modifications (PTMs) represented by glycosylation, ubiquitination, SUMOylation, acetylation, phosphorylation, palmitoylation, and lactylation are closely related to drug resistance. PTMs are typically achieved by adding sugar chains (glycosylation), small proteins (ubiquitination), lipids (palmitoylation), or functional groups (lactylation) to amino acid residues.

Misinformation exploits outrage to spread online.

We tested a hypothesis that misinformation exploits outrage to spread online, examining generalizability across multiple platforms, time periods, and classifications of misinformation. Outrage is highly engaging and need not be accurate to achieve its communicative goals, making it an attractive signal to embed in misinformation. In eight studies that used US data from Facebook (1,063,298 links) and Twitter (44,529 tweets, 24,007 users) and two behavioral experiments (1475 participants), we show that (i) misinformation sources evoke more outrage than do trustworthy sources; (ii) outrage facilitates the sharing of misinformation at least as strongly as sharing of trustworthy news; and (iii) users are more willing to share outrage-evoking misinformation without reading it first.

Natural products: promising therapeutics for targeting regulatory immune cells in the tumor microenvironment.

Regulatory immune cells regulate immune responses through various mechanisms, affecting the occurrence, development, and therapeutic effects of tumors. In this article, we reviewed the important roles of regulatory immune cells, such as regulatory T cells (Tregs), regulatory B cells (Bregs), myeloid-derived suppressor cells (MDSCs), regulatory dendritic cells (DCregs), and tumor-associated macrophages (TAMs), in the tumor microenvironment (TME). The immunomodulatory effects of natural products, such as polysaccharides, polyphenols, glycosides, alkaloids, terpenoids, quinones, and other compounds, which affect the functions of regulatory immune cells through molecular signaling pathways, thereby enhancing the potential of the antitumor immune response, are discussed.
