AbstractGenomic imprinting is implicated in the control of gene dosage in neurogenic niches. Here we address the importance of Igf2 imprinting for murine adult neurogenesis in the subventricular zone (SVZ) and in the subgranular zone (SGZ) of the hippocampus in vivo. In the SVZ, paracrine IGF2 is a cerebrospinal fluid and endothelial-derived neurogenic factor requiring biallelic expression, with mutants having reduced activation of the stem cell pool and impaired olfactory bulb neurogenesis. In contrast, Igf2 is imprinted in the hippocampus acting as an autocrine factor expressed in neural stem cells (NSCs) solely from the paternal allele. Conditional mutagenesis of Igf2 in blood vessels co…

Differential genomic imprinting regulates paracrine and autocrine roles of IGF2 in mouse adult neurogenesis

Post-operative computed tomography imaging evaluation of ascending aorta surgery

2021

Ascending thoracic aorta disease is often a life-threatening condition. Aortic aneurysm and aortic dissection are the most frequent ascending aorta diseases requiring surgical intervention. Surgical repair techniques of the ascending aorta are various; they include reconstruction of the ascending aorta by using a graft with or without a prosthetic valve, reconstruction with a composite artificial graft or using a biological graft, and reconstruction of the ascending aorta with a composite graft preserving the native valve and arch repair. The radiologist plays a key role in the identification of post-operative complications; differentiation from normal postoperative findings is fundamental.…

Relapse risk after autologous transplantation in patients with newly diagnosed myeloma is not related with infused tumor cell load and the outcome is…

2006

BACKGROUND AND OBJECTIVES: This European Group for Blood and Marrow Transplantation (EBMT) multicentre randomized phase III study was designed to assess the safety and efficacy of CD34+ selection in newly diagnosed myeloma patients undergoing autologous transplantation. DESIGN AND METHODS: One hundred and eleven patients responsive to initial chemotherapy were randomized to receive CD34+ selected (arm A) or unselected PBPC (arm B) after conditioning with high-dose melphalan and TBI. ASO-PCR was used to assess purging efficacy and reinfused tumor load. Tumor load could be assessed in 59 patients. RESULTS: CD34+ selection gave a median tumor cell depletion of 2.2 logs (0.77-5.96). No tumor ce…

Floor of the mouth hemorrhage subsequent to dental implant placement in the anterior mandible

2019

Abstract Complications in dental implant surgery are possible. Bleeding complications have been described that may be serious, particularly in the floor of the mouth. We present two cases of sublingual hematomas during dental implant osteotomies that impeded but did not close the airway. The clinical courses of these patient’s complications are reviewed. One patient had immediate hematoma formation while the other developed a hematoma overnight, presenting the next day. The treatment rendered was a precautionary in-hospital tracheotomy for the first patient and only compression control for the second. Bleeding complications during dental implant placement in the anterior mandible can be ser…

Heat Shock Proteins in Renal Cell Carcinomas

2005

Renal cell carcinoma (RCC) represents one of the most common cancer types in the Western World. One third of the RCC patients had metastasis at presentation with a poor 5-year survival. Nephrectomy is the most important treatment modality of this disease, since most of the RCCs are resistant to cytotoxic chemotherapy and radiation therapy. Recent immunotherapeutic approaches have been shown to improve the survival rate of RCC patients. Thus, RCC appears to have an immunogenic basis, and therefore represents an attractive target for immunotherapies. So far, only a few RCC-associated antigens have been characterized. However, with the implementation of ome-based technologies, an increasing nu…

Is the ADA/EASD algorithm for the management of type 2 diabetes (January 2009) based on evidence or opinion? A critical analysis

2010

The ADA and the EASD recently published a consensus statement for the medical management of hyperglycaemia in patients with type 2 diabetes. The authors advocate initial treatment with metformin monotherapy and lifestyle modification, followed by addition of basal insulin or a sulfonylurea if glycaemic goals are not met (tier 1 recommendations). All other glucose-lowering therapies are relegated to a secondary (tier 2) status and only recommended for selected clinical settings. In our view, this algorithm does not offer physicians and patients the appropriate selection of options to individualise and optimise care with a view to sustained control of blood glucose and reduction both of diabe…

Choroidal thickness is associated with renal hemodynamics in essential hypertension

2020

The choroid is the most vascularized structure of the eye and plays a central role in the development of the retinal vascular changes that occur in arterial hypertension. Changes of choroidal thickness (ChT) assessed by optical coherence tomography (OCT) technology could reflect the vascular complications of hypertension. Also, intrarenal hemodynamic damage, associated with endothelial dysfunction, demonstrated to be a good indicator of systemic morphofunctional arterial impairment. The aim of this study is to assess the relationship between ChT and renal hemodynamics in subjects with essential hypertension. Routine laboratory tests, clinical history, and physical examination, including blo…

Femoral Versus Radial Artery Access for CTO PCIs: Is This the Final Round?

2022

Historically, cardiac catheterization has been performed via transfemoral access (TFA). Although TFA remains necessary in multiple diagnostic and interventional settings, this technique has been associated with vascular access site complication rates ranging from 2% to 6%, prolonged hospital stay, and more deaths compared with radial artery access. Furthermore, safe utilization of the femoral artery can be compromised by abdominal obesity, atherosclerosis at the puncture site, and antithrombotic therapy, all which increase the bleeding risk.1 In the last decade, transradial artery access (TRA) emerged as the recommended approach for percutaneous coronary interventions (PCI), particularly in…

Fabry Disease With Concomitant Lewy Body Disease

2019

AbstractAlthough Gaucher disease can be accompanied by Lewy pathology (LP) and extrapyramidal symptoms, it is unknown if LP exists in Fabry disease (FD), another progressive multisystem lysosomal storage disorder. We aimed to elucidate the distribution patterns of FD-related inclusions and LP in the brain of a 58-year-old cognitively unimpaired male FD patient suffering from predominant hypokinesia. Immunohistochemistry (CD77, α-synuclein, collagen IV) and neuropathological staging were performed on 100-µm sections. Tissue from the enteric or peripheral nervous system was unavailable. As controls, a second cognitively unimpaired 50-year-old male FD patient without LP or motor symptoms and 3…
