Two-Week Aflibercept or Erlotinib Administration Does Not Induce Changes in Intestinal Morphology in Male Sprague–Dawley Rats But Aflibercept Affects…

2019

Gastrointestinal toxicity is a frequently observed adverse event during cancer treatment with traditional chemotherapeutics. Currently, traditional chemotherapeutics are often combined with targeted biologic agents. These biologics, however, possess a distinct toxicity profile, and they may also exacerbate the adverse effects of traditional chemotherapeutics. In this study, we aimed to characterize the gastrointestinal and metabolic changes after a 2-week treatment period with aflibercept, an antiangiogenic VEGFR decoy, and with erlotinib, a tyrosine-kinase inhibitor. Male rats were treated either with aflibercept or erlotinib for 2 weeks. During the 2-week treatment period, the animals in …

Expansion of permanent first molars with rapid maxillary expansion appliance anchored on primary second molars

2018

Background To evaluate how the amount of expansion of the primary second molars, the patient's age, and the skeletal maturation stage influence the amount of expansion at the level of the permanent first molars. Material and methods Fifty-five patients aged between 6 and 11 years with a cervical vertebral maturation stage of CS1 or CS2 were retrospectively selected. The intermolar width was measured before and after expansion to evaluate the amount of expansion achieved at the level of the primary second molars and the permanent first molars. Stepwise multiple linear regression was used to evaluate how the amount of primary molars expansion, the patient's age, and the cervical vertebral mat…

IL-33 promotes food anaphylaxis in epicutaneously sensitized mice by targeting mast cells

2016

Background Cutaneous exposure to food allergens predisposes to food allergy, which is commonly associated with atopic dermatitis (AD). Levels of the epithelial cytokine IL-33 are increased in skin lesions and serum of patients with AD. Mast cells (MCs) play a critical role in food-induced anaphylaxis and express the IL-33 receptor ST2. The role of IL-33 in patients with MC-dependent food anaphylaxis is unknown. Objective We sought to determine the role and mechanism of action of IL-33 in patients with food-induced anaphylaxis in a model of IgE-dependent food anaphylaxis elicited by oral challenge of epicutaneously sensitized mice. Methods Wild-type, ST2-deficient, and MC-deficient Kit W-sh/…

Nano-Enhanced Cancer Immunotherapy: Immunology Encounters Nanotechnology

2020

Cancer immunotherapy utilizes the immune system to fight cancer and has already moved from the laboratory to clinical application. However, and despite excellent therapeutic outcomes in some hematological and solid cancers, the regular clinical use of cancer immunotherapies reveals major limitations. These include the lack of effective immune therapy options for some cancer types, unresponsiveness to treatment by many patients, evolving therapy resistance, the inaccessible and immunosuppressive nature of the tumor microenvironment (TME), and the risk of potentially life-threatening immune toxicities. Given the potential of nanotechnology to deliver, enhance, and fine-tune cancer immunothera…

Interference of carbidopa and other catechols with reactions catalyzed by peroxidases

2018

Abstract Background A number of compounds, including ascorbic acid, catecholamines, flavonoids, p-diphenols and hydrazine derivatives have been reported to interfere with peroxidase-based medical diagnostic tests (Trinder reaction) but the mechanisms of these effects have not been fully elucidated. Methods Reactions of bovine myeloperoxidase with o-dianisidine, bovine lactoperoxidase with ABTS and horseradish peroxidase with 4-aminoantipyrine/phenol in the presence of carbidopa, an anti-Parkinsonian drug, and other catechols, including l -dopa, were monitored spectrophotometrically and by measuring hydrogen peroxide consumption. Results Chromophore formation in all three enzyme/substrate sy…

Residual tumor micro-foci and overwhelming regulatory T lymphocyte infiltration are the causes of bladder cancer recurrence

2016

Bladder cancer has an unexplained, high recurrence rate. Causes of recurrence might include the presence of sporadic tumor micro-foci in the residual urothelial tissue after surgery associated with an inverted ratio between intratumoral effector and regulatory T cell subsets. Hence, surgical specimens of both tumors and autologous, macroscopically/histologically free-of-tumor tissues were collected from 28 and 20 patients affected by bladder or renal cancer, respectively. The frequencies of effector (IFNγ+ and IL17+ T cells) and regulatory (CD4+CD25hiCD127lo and CD8+CD28-CD127loCD39+ Treg) T cell subpopulations among tumor infiltrating lymphocytes were analyzed by immunofluorescence, while …

Quality of Life in Individuals with Diabetic Foot Syndrome.

2020

Background and Objective: Diabetic foot syndrome (DFS) is a common long-term complication of diabetes mellitus. DFS has recently been associated with adverse effects that could further impair the quality of life of diabetic patients, and increase the social and economic burden, morbidity, and premature mortality of the disease. The main physio-pathological basis of DFS is due to diabetesinduced neuropathy and angiopathy in the lower limbs and feet. Patients diagnosed with DFS must significantly modify their daily habits in order to cope with signs and symptoms of DFS and this can alter their quality of life. The objective of this review is to summarize the evidence regarding the economic, …

Prognostic Challenges of SCN1A Genetic Mutations: Report on Two Children with Mild Features

2016

Mutations in the gene encoding the α-1 subunit of the voltage-gated sodium channel (SCN1A) are associated with variable but usually severe clinical course, both for the epileptic seizures and the cognitive impairment. The purpose of the present study was to retrospectively review two patients affected by seizures and two different types of SCN1A gene mutations (microdeletion and point mutation). The children (a 4-year-old girl and a 3-year-old boy) were affected by generalized tonic–clonic seizures and myoclonic jerks plus unilateral seizures, respectively. Genetic analyses showed, in the girl, the presence of a 4 MB deletion involving SCN1A and four other genes, and a point mutation in the…

2017

Whether the central nervous system is capable to switch between contexts critically depends on experimental details. Motor control studies regularly adopt robotic devices to perturb the dynamics of a certain task. Other approaches investigate motor control by altering the gravitoinertial context itself as in parabolic flights and human centrifuges. In contrast to conventional robotic experiments, where only the hand is perturbed, these gravitoinertial or immersive settings coherently plunge participants into new environments. However radically different they are, perfect adaptation of motor responses are commonly reported. In object manipulation tasks, this translates into a good matching o…
