Sodium glucose cotransporter 2 inhibitors are expected to ameliorate the abnormalities associated with metabolic syndrome including non-alcoholic fatty liver disease. In this study, we investigated the effects of the sodium glucose cotransporter 2 inhibitor tofogliflozin on the development of non-alcoholic fatty liver disease-related liver tumorigenesis in C57BL/KsJ-+Leprdb/+Leprdb obese and diabetic mice. The direct effects of tofogliflozin on human liver cancer cell proliferation were also evaluated. Mice were administered diethylnitrosamine-containing water for 2 weeks and were treated with tofogliflozin throughout the experiment...

AIM: Disease activity assessment in Takayasu arteritis (TA) is challenging. Human leukocyte antigen E (HLA-E) is shed from endothelium into serum as a soluble molecule (sHLA-E) in response to inflammation. We aimed to study: (i) utility of sHLA-E as a biomarker of disease activity; and (ii) association of HLA-E polymorphism rs1264457 with clinical disease in Asian-Indian TA patients. MATERIALS AND METHODS: In phase-1, sHLA-E levels were estimated in sera of 50 consecutive TA patients at baseline visit and 27 healthy controls...

Takayasu arteritis is a rare, chronic vasculitis of unknown etiology characterized by inflammation of the aorta and its main branches. Although Takayasu arteritis mostly affects women of childbearing age, there is a paucity in the literature on pregnancy associated with Takayasu arteritis. Pregnant patients are at increased risk of cardiovascular complications, including hypertension and congestive heart failure, which may jeopardize both maternal and fetal outcomes. Furthermore, optimal management has not yet been established for pregnant patients with Takayasu arteritis, posing a clinical challenge...

Mutations in the with-no-lysine kinase 1 (WNK1), WNK4, Kelch-like 3 (KLHL3), and Cullin3 (CUL3) genes were identified as being responsible for hereditary hypertensive disease pseudohypoaldosteronism type II (PHAII). Normally, the KLHL3/CUL3 ubiquitin ligase complex degrades WNKs. In PHAII, the loss of interaction between KLHL3 and WNK4 increases levels of WNKs because of impaired ubiquitination, leading to abnormal over-activation of the WNK-OSR1/SPAK-NCC cascade in the kidney's distal convoluted tubules (DCT)...

Environmental stimulation during brain development is an important risk factor for the development of neurodegenerative disease. Clinical evidence indicates that prenatal exposure to particulate air pollutants leads to diffuse damage to the neurovascular unit in the developing brain and accelerates neurodegeneration. Maternal exposure to carbon black nanoparticles (CB-NPs), used as a model for particulate air pollution, induces long-lasting diffuse perivascular abnormalities. We aimed to comprehensively characterize the perivascular abnormalities related to maternal NPs exposure using Fourier transform infrared microspectroscopy (in situ FT-IR) and classical staining analysis...

Takayasu arteritis is a rare, idiopathic inflammatory disease of the aorta and its major branches, usually affecting young women of Asian descent. In the course of the disease stenosis, occlusions as well as dilatations and aneurysms of vessels occur. Because of many possible localizations of pathological changes, the symptoms have a wide range, but the most common are a weak pulse or its absence on the brachial artery and a difference in systolic pressure above 10 mm Hg between the upper extremities. Here we present a case report of a young woman with Takayasu arteritis, who presented a palpable mass in the back of her neck, significantly diminished after treatment with glucocorticoids...

INTRODUCTION: Diffuse leptomeningeal glioneuronal tumor is a new entity under the neuronal and mixed neuronal-glial tumors in the WHO 2016 updated classification and commonly found in children and adolescents. The initial diagnosis is challenging because of its non-specific radiologic feature and negative CSF cytology analysis. A 17 years male was presented with intractable headache subsequently followed by back pain and joint pain. MRI showed enhancement of arachnoid membrane at basal cistern, bilateral sylvian fissure and cerebral cistern with slight enlargement of ventricles...

Coronary arterial involvement in Takayasu arteritis (TA) is not uncommon. Herein, we describe a case of TA with celiac trunk and superior mesenteric artery occlusion combined with coronary artery disease. Bilateral huge internal thoracic arteries (ITAs) and the inferior mesenteric artery provided the major visceral collateral circulation. After percutaneous intervention to the right coronary artery, off-pump coronary artery bypass grafting for the left coronary territory was done using a right ITA graft and its large side branch because of its relatively minor contribution to the visceral collateral circulation...

Takayasu's arteritis (TAK) is a rare, chronic, large-vessel vasculitis (LVV) that predominantly affects aorta, its major branches and the pulmonary arteries. Recent controversial issues in the diagnosis, disease assessment and prognosis in TAK are discussed in this review. In recent years, conventional angiography, the standard method for the initial diagnosis, seems to have been replaced by the new imaging modalities, such as MRI and 18F-FDG-PET. Less invasive techniques (CT/MRI) are now suggested first, compared to conventional angiography, and MRI is preferable to CT with less contrast load/radiation...

BACKGROUND: Chronic subdural hematoma (CSDH) is considered an angiogenic and inflammatory disease. Nuclear factor-kappa B (NF-κB) induces the production of inflammatory cytokines and adhesion molecules, which play an essential role in angiogenesis and inflammation. Recently, the double-stranded RNA-activated protein kinase (PKR) was shown to directly interact with NF-κB subunits to influence its transcriptional activity. OBJECTIVE: To examine the expression of NF-κB signaling pathway components and PKR in CSDH outer membranes...
