Динамическая съемка миелинской патологии в физиологически сохранившихся человеческих мозговых тканях с использованием третьей гармонической микроскопии.

Известно, что миелиновая патология играет центральную роль в таких расстройствах, как, в частности, множественный склероз (MS). Несмотря на это, патологические механизмы, лежащие в основе этих условий, часто трудно разгадать. Обычные методы, такие, как иммуноистохимия или подходы, основанные на красителях, не обеспечивают временной характеристики патофизиологических отклонений, вызывающих миелиновые изменения в образцах человека. Здесь, чтобы обойти эту обочину, мы представляем подход миелина к изображениям без ярлыков с живыми клетками, используя недавние достижения в нелинейной гармонической

State of the Art of Cardiac Amyloidosis.

Cardiac amyloidosis is defined by extracellular deposition of misfolded proteins in the heart. The most frequent cases of cardiac amyloidosis are caused by transthyretin and light chain amyloidosis. This condition is underdiagnosed, and its incidence has been continuously rising in recent studies because of the aging of the population and the development of noninvasive multimodal diagnostic tools. Amyloid infiltration affects all cardiac tunics and causes heart failure with preserved ejection fraction, aortic stenosis, arrythmia, and conductive disorder. Innovative, specific therapeutic approa

Managing thrombosis in cancer patients.

Venous thromboembolism is a major complication in cancer patients. The basis for the strong association between cancer and thrombosis remains incompletely understood, and the optimal approaches to both the treatment and the prevention of cancer-associated thrombosis are evolving. Here we review several important topics related to cancer-associated thromboembolism, including the pathogenesis, prevention, and management of this disease. Wherever possible, we include evidence from clinical trials, including the results of recently published trials that compared direct oral anticoagulants to low-m

High-Dose Vitamin C for Cancer Therapy.

In recent years, the idea that Vitamin C (Vit-C) could be utilized as a form of anti-cancer therapy has generated many contradictory arguments. Recent insights into the physiological characteristics of Vit-C, its pharmacokinetics, and results from preclinical reports, however, suggest that high-dose Vit-C could be effectively utilized in the management of various tumor types. Studies have shown that the pharmacological action of Vit-C can attack various processes that cancerous cells use for their growth and development. Here, we discuss the anti-cancer functions of Vit-C, but also the potenti

The Osteoclast in Bone Metastasis: Player and Target.

Bone metastases are frequently the final fate of breast and prostate cancer patients. According to the definition of metastasis as an incurable disease, to date there are no effective treatments for tumor-associated bone metastases and this represents a real challenge for the researchers in the field. The bone is a heterogeneous environment that represents a fertile soil for tumor cells, supporting their growth. Among the different cell types present in the bone, in this review we will focus our attention on the osteoclasts, which are crucial players in the so called “vicious cycle”, a phenome

Study of a novel Ca/P/S-based cement implanted in the osteoporotic goat spine and its clinical application in preventing adjacent vertebral fractures.

Osteoporotic vertebral compression fracture (OVCF) has been increasing over the last decades. In addition to primary OVCF, the adjacent vertebral fracture (AVF) is a frequent serious complication in OVCF patients receiving percutaneous vertebroplasty or kyphoplasty, resulting in poor long-term outcome and recurrent symptoms. The aim of the present study is to investigate the bone regeneration behavior of a novel Ca/P/S-based resorbable cement (Ezechbone® Cement CBC-400) implanted into surgically created vertebral defects of ovariectomized (OVX) goats. Furthermore, the present study provides a

Overview of Ankle Arthropathy in Hereditary Hemochromatosis.

Hereditary hemochromatosis (HH) is an autosomal recessive bleeding disorder characterized by tissue overload of iron. Clinical systemic manifestations in HH include liver disease, cardiomyopathy, skin pigmentation, diabetes mellitus, erectile dysfunction, hypothyroidism, and arthropathy. Arthropathy with joint pain is frequently reported at diagnosis and mainly involves the metacarpophalangeal and ankle joints, and more rarely, the hip and knee. Symptoms in ankle joints are in most cases non-specific, and they can range from pain and swelling of the ankle to deformities and joint destruction.

Exploring the Complexity and Promise of Tumor Immunotherapy in Drug Development.

Cancer represents a significant threat to human health, and traditional chemotherapy or cytotoxic therapy is no longer the sole or preferred approach for managing malignant tumors. With advanced research into the immunogenicity of tumor cells and the growing elderly population, tumor immunotherapy has emerged as a prominent therapeutic option. Its significance in treating elderly cancer patients is increasingly recognized. In this study, we review the conceptual classifications and benefits of immunotherapy, and discuss recent developments in new drugs and clinical progress in cancer treatment

Novel therapeutic approaches for pulmonary fibrosis.

Pulmonary fibrosis represents the end stage of a number of heterogeneous conditions and is, to a greater or lesser degree, the hallmark of the interstitial lung diseases. It is characterized by the excessive deposition of extracellular matrix proteins within the pulmonary interstitium leading to the obliteration of functional alveolar units and in many cases, respiratory failure. While a small number of interstitial lung diseases have known aetiologies, most are idiopathic in nature, and of these, idiopathic pulmonary fibrosis is the most common and carries with it an appalling prognosis - med

A Holistic Review of Oncological Drug Targets and Trajectories of Resistance in Cancer Therapy.

Clinical review: specific aspects of acute renal failure in cancer patients.

Acute renal failure (ARF) in cancer patients is a dreadful complication that causes substantial morbidity and mortality. Moreover, ARF may preclude optimal cancer treatment by requiring a decrease in chemotherapy dosage or by contraindicating potentially curative treatment. The pathways leading to ARF in cancer patients are common to the development of ARF in other conditions. However, ARF may also develop due to etiologies arising from cancer treatment, such as nephrotoxic chemotherapy agents or the disease itself, including post-renal obstruction, compression or infiltration, and metabolic o

Roles of Microvesicles in Tumor Progression and Clinical Applications.

Microvesicles are extracellular vesicles with diameter ranging from 100 to 1000 nm that are secreted by tumor cells or other cells in the tumor microenvironment. A growing number of studies demonstrate that tumor-derived microvesicles are involved in tumor initiation and progression, as well as drug resistance. In addition, tumor-derived microvesicles carry a variety of immunogenic molecules and inhibit tumor response to immunotherapy; therefore, they can be exploited for use in tumor vaccines. Moreover, because of their high stability, tumor-derived microvesicles extracted from body fluids ca

The progression of HMGB1-induced autophagy in cancer biology.

Autophagy is an important process of cellular degradation and has been proven to contribute to tumorigenesis. High-mobility group box 1 (HMGB1) is an abundant nonhistone protein that has been widely reported to play a central role in the induction of autophagy. In nucleus, HMGB1 upregulates the expression of HSP27 to induce autophagy. In cytoplasm, the Beclin-1/PI3K-III complex can be activated by HMGB1 to promote autophagy. Extracellular HMGB1 binds to the receptor for advanced glycation end products to induce autophagy. Recent studies have shown that HMGB1-induced autophagy exerts multiple f
