The accurate definition and staging of chronic kidney disease (CKD) is one of the major achievements of modern nephrology. Intensive research is now being undertaken to unravel the risk factors and pathophysiologic underpinnings of this disease. In particular, the relationships between the kidney and other organs have been comprehensively investigated in experimental and clinical studies in the last two decades. Owing to technological and analytical limitations, these links have been studied with a reductionist approach focusing on two organs at a time, such as the heart and the kidney or the bone and the kidney...

Polyurethanes are a diverse class of polymers, with independently tunable mechanical and biodegradation properties making them a versatile platform material for biomedical implants. Previous iterations have failed to adequately embody appropriate mechanical and biological properties, particularly for vascular medicine where strength, compliance and multifaceted biocompatibility are required. We have synthesized a new polyurethane formulation with finely tuned mechanical properties, combining high strength and extensibility with a low Young's modulus...

The ACGME currently approves fellowship training in 11 subspecialties of radiology, and the ABR currently offers six subspecialty certificates (vascular interventional radiology will be phased out in 2017) to its primary certificate holders. Four of the ABR-sponsored or co-sponsored subspecialties have been available to ABR diplomates for more than 18 years, but two-hospice and palliative medicine and pain medicine-are relatively new. The nature of specialty and subspecialty certificate development and details related to these two specific programs will be considered...

Hyperoside is a major active constituent in many medicinal plants traditionally used in Chinese medicines for their anti-inflammatory, antioxidative, and vascular protective effects. Recent studies have focused on the protective effects of hyperoside on hyperlipidemia. However, the molecular mechanisms underlying these effects are unknown. In this study, vascular smooth muscle cells (VSMCs) were treated in vitro with oxidized low-density lipoprotein (oxLDL) in the presence or absence of hyperoside. Western blotting, quantitative PCR, and tetrazolium assay were used to detect lectin-like oxLDL receptor-1 (LOX-1) expression and extracellular signal-regulated kinases (ERK) activation, and to determine VSMCs viability...

BACKGROUND: Ficus carica Linn. (Fc), common fig, has been traditionally used for many metabolic, cardiovasculary, respiratory, gastrointestinal, and skin disorders. Several studies were performed showing its anti-inflammatory, anti-angiogenic, anticancerogenic, and tissue-protective effects. In all of those studies, the positive effects of Fc were concluded as the result of its antioxidant and anti-inflammatory features due to the polyphenols it contains. AIMS: To study the phenolic compounds of Fc extract and to investigate the molecular basis of anti-inflammatory, anti-angiogenic, antimitotic, and anti-androgenic effects of Fc leaf extract in vitro...

Physical activity has profound impacts on the vasculature in humans. Acute exercise induces immediate changes in artery function, whereas repeated episodic bouts of exercise induce chronic functional adaptation and, ultimately, structural arterial remodeling. The nature of these changes in function and structure are dependent on the characteristics of the training load and may be modulated by other factors such as exercise-induced inflammation and oxidative stress. The clinical implications of these physiological adaptations are profound...

BACKGROUND CONTEXT: Severe adolescent idiopathic scoliosis (AIS) is a 3D spinal deformity requiring surgery to stop curve progression. Posterior spinal instrumentation and fusion with pedicle screws is the standard surgery for AIS curve correction. Vascular and neurologic complications related to screw-malpositioning are concerns in surgeries for AIS. Breach rates are reported at 15.7%, implant-related complications at 1.1% and neurologic deficit at 0.8%. Free-hand screw insertion remains the prevailing method of screw placement while image guidance has been suggested to improve placement accuracy...

Mesenchymal stromal cells (MSCs) from different sources have differential effects on lung injury. To compare the effects of murine MSCs from bone marrow (BM), adipose tissue (AD), and lung tissue (LUNG) on inflammatory and remodeling processes in experimental allergic asthma, female C57BL/6 mice were sensitized and challenged with ovalbumin (OVA) or saline (C). Twenty-four hours after the last challenge, mice received either saline (50 µl, SAL), BM-MSCs, AD-MSCs, or LUNG-MSCs (10(5) cells per mouse in 50 µl total volume) intratracheally...

Pseudolaric acid B (PAB) is the most active constituent extracted from the bark of Pseudolarix kaempferi, which has been used as an antifungal remedy in traditional Chinese medicine. It is reported to have cytotoxicity to many tumor cell lines. In this study, we investigated the effects of PAB against human endometrial cancer Ishikawa cells. We found that PAB inhibited Ishikawa cell proliferation, and induced cell apoptosis and G2/M phase arrest through a mechanism involving AKT-GSK-3β and ERK1/2 signaling pathways...

PURPOSE: This work presents an approach to mapping the entire lung's proton density and T1 within a single breath-hold and analyzes the apparent T1 when exciting with a spin echo generating pulse in comparison to a standard gradient echo acquisition. METHODS: An inversion-recovery SNAPSHOT-FLASH sequence with a stack-of-stars k-space readout with a golden angle increment was modified to use a spin echo generating radiofrequency-pulse for excitation. Data of five volunteers were acquired on a 3T scanner and image reconstruction was performed by an iterative algorithm adopted from MR-Fingerprinting...

In chronic myeloid leukemia (CML) resistance against one or more BCR-ABL1 tyrosine kinase inhibitors (TKI) remains a clinical challenge. Preclinical data suggest that TKI combinations may overcome resistance. We report on a heavily pre-treated 78 year-old female patient with CML who developed multi-resistant blast crisis with bone marrow fibrosis and a Ph- clone. Treatment with ponatinib resulted in blast cell clearance, decrease in fibrosis, and disappearance of BCR-ABL1, but also in severe thrombocytopenia with bleedings requiring platelet transfusions...

Administration of drugs and other therapeutic agents has been the central strategy of contemporary medicine for cardiovascular disease. The use of drug delivery systems (DDS) includes micelles, liposomes, polymeric nanoparticles, dendrimers, carbon nanotubes, and crystalline metals. Nano-DDS modify in vivo drug kinetics, depending on (patho)physiological mechanisms such as retard excretion, vascular permeability, and incorporation by mononuclear phagocyte systems, which constitute the 'passive-targeting' property of nano-DDS...

Despite the efforts in developing therapeutics for stroke, recombinant tissue plasminogen activator (rtPA) remains the only FDA approved drug for ischemic stroke. Regenerative medicine targeting endogenous growth factors has drawn much interest in the clinical field as it provides potential restoration for the damaged brain tissue without being limited by a narrow therapeutic window. To date, most of the translational studies using regenerative medicines have encountered problems and failures. In this review, we discuss the effects of some trophic factors which include of erythropoietin (EPO), brain derived neurotrophic factor (BDNF), granulocyte-colony stimulating factor (G-CSF), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), epidermal growth factor (EGF) and heparin binding epidermal growth factor (HB-EGF) in experimental ischemic stroke models and elaborate the lost in translation of the candidate growth factors from bench to bedside...
