Nanoparticles for Targeted Drug Delivery to Cancer Stem Cells: A Review of Recent Advances.

Cancer stem cells (CSCs) are a subpopulation of cells that can initiate, self-renew, and sustain tumor growth. CSCs are responsible for tumor metastasis, recurrence, and drug resistance in cancer therapy. CSCs reside within a niche maintained by multiple unique factors in the microenvironment. These factors include hypoxia, excessive levels of angiogenesis, a change of mitochondrial activity from aerobic aspiration to aerobic glycolysis, an upregulated expression of CSC biomarkers and stem cell signaling, and an elevated synthesis of the cytochromes P450 family of enzymes responsible for drug

Risk factors for medication-related osteonecrosis of the jaw and salivary IL-6 IN cancer patients.

INTRODUCTION: Medication-related osteonecrosis of the jaws is a severe complication of the use of antiresorptive and antiangiogenic therapy, with limited treatment options and great impact on patient's quality pf life. OBJECTIVE: The aim of this study was to assess the risk factors associated with medication-related osteonecrosis of the jaws in oncologic patients undergoing bisphosphonate treatment. In addition, salivary levels of interleukin-6, IL-6, were measured to investigate their association with severity and risk of medication-related osteonecrosis of the jaws. METHODS: Case-control s

Circulating Levels of Soluble α-Klotho and FGF23 in Childhood Cancer Survivors: Lack of Association with Nephro- and Cardiotoxicity-A Preliminary Study.

Background/Objectives: The survival rate among pediatric cancer patients has reached 80%; however, these childhood cancer survivors (CCSs) are at a heightened risk of developing chronic conditions in adulthood, particularly kidney and cardiovascular diseases. The aims of this study were to assess the serum α-Klotho and FGF23 levels in CCSs and to determine their association with nephro- and cardiotoxicity. Methods: This study evaluated a cohort of 66 CCSs who remained in continuous remission, with a mean follow-up of 8.41 ± 3.76 years. Results: The results of this study revealed that CCSs exhi

Cancer Stem Cells: The Potential Targets of Chinese Medicines and Their Active Compounds.

The pivotal role of cancer stem cells (CSCs) in the initiation and progression of malignancies has been rigorously validated, and the specific methods for identifying and isolating the CSCs from the parental cancer population have also been rapidly developed in recent years. This review aims to provide an overview of recent research progress of Chinese medicines (CMs) and their active compounds in inhibiting tumor progression by targeting CSCs. A great deal of CMs and their active compounds, such as Antrodia camphorate, berberine, resveratrol, and curcumin have been shown to regress CSCs, in t

Маркеры повреждения аксона в крови и тканях, вызванные острым и хроническим обезвоживанием.

Нейроаксональная травма является одним из основных факторов необратимой инвалидности в условиях демиелионации. Точная оценка связи между демиэлированием и аксонной патологией имеет решающее значение для оценки и разработки эффективных терапевтических подходов. Измерение световой цепи нейрофильтрации (NfL) в крови может, вероятно, позволить продольный мониторинг нейроаксональной травмы при "едином белке разрешения" с высокой патологической спецификой. Здесь мы демонстрируем прочную связь между кровью и тканями, основанными на NfL, оценкой нейроаксональных повреждений и серьезностью подстрекател

INTRODUCTION: Hyperammonemia is a life-threatening condition most associated with liver disease, though non-cirrhotic causes are increasingly recognized. CASE PRESENTATION: We report an 18-year-old female presenting with 1 week of progressive confusion, abdominal pain, and nausea. Initial evaluation showed normal routine laboratories but markedly elevated ammonia and respiratory alkalosis. She rapidly deteriorated, requiring intubation and intensive care. Ammonia peaked at 795 µg/dL and improved rapidly after urgent venous hemofiltration and medical therapy, with full neurological recovery by

Use of 15-Valent Pneumococcal Conjugate Vaccine and 20-Valent Pneumococcal Conjugate Vaccine Among U.S. Adults: Updated Recommendations of the Advisory Committee on Immunization Practices - United States, 2022.

In 2021, 20-valent pneumococcal conjugate vaccine (PCV) (PCV20) (Wyeth Pharmaceuticals LLC, a subsidiary of Pfizer Inc.) and 15-valent PCV (PCV15) (Merck Sharp & Dohme Corp.) were licensed by the Food and Drug Administration for adults aged ≥18 years, based on studies that compared antibody responses to PCV20 and PCV15 with those to 13-valent PCV (PCV13) (Wyeth Pharmaceuticals LLC, a subsidiary of Pfizer Inc.). Antibody responses to two additional serotypes included in PCV15 were compared to corresponding responses after PCV13 vaccination, and antibody responses to seven additional serotypes i

Pamidronate disodium for palliative therapy of feline bone-invasive tumors.

This study sought to quantify in vitro antiproliferative effects of pamidronate in feline cancer cells and assess feasibility of use of pamidronate in cats by assessing short-term toxicity and dosing schedule in cats with bone-invasive cancer. A retrospective pilot study included eight cats with bone invasive cancer treated with intravenous pamidronate. In vitro, pamidronate reduced proliferation in feline cancer cells (P < 0.05). One cat treated with pamidronate in combination with chemotherapy and two cats treated with pamidronate as a single agent after failing prior therapy had subjective

The Mechanisms of Altered Blood-Brain Barrier Permeability in CD19 CAR T-Cell Recipients.

Cluster of differentiation 19 (CD19) chimeric antigen receptor (CAR) T cells are a highly effective immunotherapy for relapsed and refractory B-cell malignancies, but their utility can be limited by the development of immune effector cell-associated neurotoxicity syndrome (ICANS). The recent discovery of CD19 expression on the pericytes in the blood-brain barrier (BBB) suggests an important off-target mechanism for ICANS development. In addition, the release of systemic cytokines stimulated by the engagement of CD19 with the CAR T cells can cause endothelial activation and decreased expression

Time to Next Treatment as a Meaningful Endpoint for Trials of Primary Cutaneous Lymphoma.

Time to next treatment (TTNT) is an emerging endpoint in clinical studies of primary cutaneous T-cell lymphomas (CTCL), with utility as a surrogate marker for the "duration of clinical benefit". TTNT provides a highly clinically meaningful endpoint that uniquely reflects not only the duration of treatment efficacy on disease and symptom control, but also incorporates the patient experience by accounting for patient compliance and tolerance to the studied therapy(s). Given the distinct challenges of pin-pointing the exact date of progression in patients with multi-compartmental CTCL, TTNT overc

Blastic plasmacytoid dendritic cell neoplasm: a short review and update.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic neoplasm (less than 1% of primary cutaneous lymphomas and acute leukemia) with a highly aggressive clinical course and frequent skin, bone marrow and central nervous system involvement. Even though there is often an early response to chemotherapy, leukemic dissemination relapses are very common and result in poor outcomes, with a median overall survival of 8 to 14 months in the first-line setting using standard combination chemotherapy regimens. Almost 90% of patients experience skin involvement as their initial site of
