Livedoid vasculopathy: A multidisciplinary clinical approach to diagnosis and management.

Livedoid vasculopathy (LV) is a rare, chronic, and occlusive disease of the veins supplying the upper parts of the skin. The pathogenesis of the disease is not precisely understood, and its attacks are often unpredictable but tend to worsen during the summer. LV affects women more often. This increased risk for LV in women might be related to sex-specific physiological conditions, such as pregnancy, or a higher incidence of LV-associated conditions, such as connective tissue diseases, hypercoagulable states, and venous stasis in women. The typical clinical appearance of LV consists of three ma

Blood Coagulation and Beyond: Position Paper from the Fourth Maastricht Consensus Conference on Thrombosis.

The Fourth Maastricht Consensus Conference on Thrombosis included the following themes. Theme 1: The "coagulome" as a critical driver of cardiovascular disease. Blood coagulation proteins also play divergent roles in biology and pathophysiology, related to specific organs, including brain, heart, bone marrow, and kidney. Four investigators shared their views on these organ-specific topics. Theme 2: Novel mechanisms of thrombosis. Mechanisms linking factor XII to fibrin, including their structural and physical properties, contribute to thrombosis, which is also affected by variation in microbio

Insights into Endothelial Progenitor Cells: Origin, Classification, Potentials, and Prospects.

With the discovery of endothelial progenitor cells (EPCs) in the late 1990s, a paradigm shift in the concept of neoangiogenesis occurred. The identification of circulating EPCs in peripheral blood marked the beginning of a new era with enormous potential in the rapidly transforming regenerative field. Overwhelmed with the revelation, researchers across the globe focused on isolating, defining, and interpreting the role of EPCs in various physiological and pathological conditions. Consequently, controversies emerged regarding the isolation techniques and classification of EPCs. Nevertheless, th

Vascular endothelial growth factor signaling in health and disease: from molecular mechanisms to therapeutic perspectives.

Vascular endothelial growth factor (VEGF) signaling is a critical regulator of vasculogenesis, angiogenesis, and lymphangiogenesis, processes that are vital for the development of vascular and lymphatic systems, tissue repair, and the maintenance of homeostasis. VEGF ligands and their receptors orchestrate endothelial cell proliferation, migration, and survival, playing a pivotal role in dynamic vascular remodeling. Dysregulated VEGF signaling drives diverse pathological conditions, including tumor angiogenesis, cardiovascular diseases, and ocular disorders. Excessive VEGF activity promotes tu

Tumor angiogenesis as a target for dietary cancer prevention.

Between 2000 and 2050, the number of new cancer patients diagnosed annually is expected to double, with an accompanying increase in treatment costs of more than $80 billion over just the next decade. Efficacious strategies for cancer prevention will therefore be vital for improving patients' quality of life and reducing healthcare costs. Judah Folkman first proposed antiangiogenesis as a strategy for preventing dormant microtumors from progressing to invasive cancer. Although antiangiogenic drugs are now available for many advanced malignancies (colorectal, lung, breast, kidney, liver, brain,

Pedicled myofascial temporalis flap for closure of large maxillary defects after medication-related osteonecrosis of the jaws. A case series.

BACKGROUND: Medication-related osteonecrosis of the jaws (MRONJ) located in the maxilla may lead to challenging oro-antral and oro-nasal defects too extensive to be predictably closed with local soft tissue flaps. The use of a pedicled myofascial temporalis flap (PMTF) is, however, well-established for closing large maxillary defects following ablative craniomaxillofacial surgery. OBJECTIVES: The purpose of the present study was to evaluate the use of PMTF for maxillary defect closure in patients with stage 3 MRONJ. METHODS: A retrospective cohort study was conducted based on data from the C

Interactions between kidney disease and diabetes: dangerous liaisons.

BackgroundType 2 diabetes mellitus (DM) globally affects 18-20 % of adults over the age of 65 years. Diabetic kidney disease (DKD) is one of the most frequent and dangerous complications of DM2, affecting about one-third of the patients with DM2. In addition to the pancreas, adipocytes, liver, and intestines, the kidneys also play an important role in glycemic control, particularly due to renal contribution to gluconeogenesis and tubular reabsorption of glucose.MethodsIn this review article, based on a report of discussions from an interdisciplinary group of experts in the areas of endocrinolo

Upregulation of long non-coding RNA myocardial infarction-associated transcription is correlated with coronary artery stenosis and elevated inflammation in patients with coronary atherosclerotic heart disease.

Coronary atherosclerotic heart disease (CAD) is a chronic disease caused by multiple risk factors. Aberrant expression of long non-coding RNAs (lncRNAs) has been regarded as an independent risk factor of CAD. This study evaluated lncRNA myocardial infarction-associated transcription (MIAT) expression in CAD patients and its clinical significance. Totally, 155 CAD patients and 76 non-CAD controls were enrolled. MIAT expression was detected using reverse transcription quantitative polymerase chain reaction. The clinical diagnostic significance of MIAT was evaluated by plotting the receiver opera

Bortezomib Increased Vascular Permeability by Decreasing Cell-Cell Junction Molecules in Human Pulmonary Microvascular Endothelial Cells.

Bortezomib (BTZ), a chemotherapeutic drug used to treat multiple myeloma, induces life-threatening side effects, including severe pulmonary toxicity. However, the mechanisms underlying these effects remain unclear. The objectives of this study were to (1) investigate whether BTZ influences vascular permeability and (2) clarify the effect of BTZ on the expression of molecules associated with cell-cell junctions using human pulmonary microvascular endothelial cells in vitro. Clinically relevant concentrations of BTZ induced limited cytotoxicity and increased the permeability of human pulmonary m

A Comprehensive Biological and Clinical Perspective Can Drive a Patient-Tailored Approach to Multiple Myeloma: Bridging the Gaps between the Plasma Cell and the Neoplastic Niche.

There is a broad spectrum of diseases labeled as multiple myeloma (MM). This is due not only to the composite prognostic risk factors leading to different clinical outcomes and responses to treatments but also to the composite tumor microenvironment that is involved in a vicious cycle with the MM plasma cells. New therapeutic strategies have improved MM patients' chances of survival. Nevertheless, certain patients' subgroups have a particularly unfavorable prognosis. Biological stratification can be subdivided into patient, disease, or therapy-related factors. Alternatively, the biological sig

Human Amniotic Membrane Dressing as a Non-Surgical Alternative for Extensive Chronic Ulcers: A Comparative Case Study.

Chronic wound management remains a significant clinical challenge, requiring adaptive therapeutic approaches to achieve wound closure that nonetheless frequently prove fruitless. Balancing the initial pro-inflammatory response with debris removal and tissue rebuilding remains elusive in most cases, leading to pain, drastic quality-of-life deterioration, and, eventually, amputation. Meanwhile, patient adherence is an overarching theme. Furthermore, non-surgical alternatives that effectively promote tissue rebuilding are essential for patients seeking to avoid further invasive procedures. We rep

New Directions in the Study and Treatment of Metastatic Cancer.

Traditional cancer therapy has relied on a strictly cytotoxic approach that views non-metastatic and metastatic tumor cells as identical in terms of molecular biology and sensitivity to therapeutic intervention. Mounting evidence suggests that, in fact, non-metastatic and metastatic tumor cells differ in key characteristics that could explain the capacity of the metastatic cells to not only escape the primary organ but also to survive while in the circulation and to colonize a distant organ. Here, we lay out a framework for a new multi-pronged therapeutic approach. This approach involves modif

RNA N 6-Methyladenosine in Cancer Metastasis: Roles, Mechanisms, and Applications.

Cancer metastasis is a symptom of adverse prognosis, a prime origin of therapy failure, and a lethal challenge for cancer patients. N 6-methyladenosine (m6A), the most prevailing modification in messenger RNAs (mRNAs) and non-coding RNAs (ncRNAs) of higher eukaryotes, has attracted increasing attention. Growing studies have verified the pivotal roles of m6A methylation in controlling mRNAs and ncRNAs in diverse physiological processes. Remarkably, recent findings have showed that aberrant methylation of m6A-related RNAs could influence cancer metastasis. In this review, we illuminate how m6A m

The Global Obesity Epidemic: Epidemiology, Health Burden and Policy Priorities.

The global prevalence of obesity has more than tripled since 1975, now affecting nearly one billion adults and over 170 million children and adolescents. In 2025, The Lancet Diabetes & Endocrinology Commission on Clinical Obesity redefined obesity as a chronic, multisystem disease characterised by excess adiposity leading to organ dysfunction, distinguishing between preclinical obesity (excess adiposity without end-organ injury) and clinical obesity (manifest metabolic or structural complications). This framework moves beyond reliance on BMI, acknowledging that ectopic fat deposition in the li

Casein Kinase 2 Inhibitor, CX-4945, Induces Apoptosis and Restores Blood-Brain Barrier Homeostasis in In Vitro and In Vivo Models of Glioblastoma.

Background: In oncology, casein kinase 2 (CK2), a serine/threonine kinase, has a dual action, regulating cellular processes and acting as an oncogenic promoter. Methods: This study examined the effect of CX-4945, a selective CK2 inhibitor, in a human U-87 glioblastoma (GBM) cell line, treated with CX-4945 (5, 10, and 15 μM) for 24 h. Similarly, the hCMEC/D3 cell line was used to mimic the blood-brain barrier (BBB), examining the ability of CX-4945 to restore BBB homeostasis, after stimulation with lipopolysaccharide (LPS) and then treated with CX-4945 (5, 10, and 15 μM). Results: We reported t

Mesenchymal stem cells: A new therapeutic tool for chronic kidney disease.

Chronic kidney disease (CKD) has a major impact on public health, which could progress to end-stage kidney disease (ESRD) and consume many medical resources. Currently, the treatment for CKD has many flaws, so more effective treatment tools are urgently required for CKD. Mesenchymal stem cells (MSCs) are primitive cells with self-renewal and proliferation capacity and differentiation potential. Extensive preclinical and clinical data has shown that cell-based therapies using MSCs can modulate immunity, inhibit inflammatory factors, and improve renal function in CKD, suggesting that MSCs have t

CircRNA ITCH: Insight Into Its Role and Clinical Application Prospect in Tumor and Non-Tumor Diseases.

CircRNA E3 ubiquitin protein ligase (ITCH) (circRNA ITCH, circ-ITCH), a stable closed-loop RNA derived from the 20q11.22 region of chromosome 20, is a new circRNA discovered in the cytoplasm in recent decades. Studies have shown that it does not encode proteins, but regulates proteins expression at different levels. It is down-regulated in tumor diseases and is involved in a number of biological activities, including inhibiting cell proliferation, migration, invasion, and promoting apoptosis. It can also alter disease progression in non-tumor disease by affecting the cell cycle, inflammatory r
