Data on treatment of glucocorticoid-induced osteoporosis (GIO) in men are scarce. We performed a randomized, open-label trial in men who have taken glucocorticoids (GC) for ≥3 months, and had an areal bone mineral density (aBMD) T-score ≤ -1.5 standard deviations. Subjects received 20 μg/d teriparatide (n = 45) or 35 mg/week risedronate (n = 47) for 18(More)
We assessed the effects on bone remodeling and histomorphometry after daily subcutaneous injections of teriparatide (n = 39, 20 microg/d) or oral strontium ranelate (SrR, n = 40, 2 g/d) in postmenopausal women with osteoporosis. Evaluable biopsies were obtained from 29 patients in the teriparatide group and 22 in the SrR group after 6 mo of treatment. The(More)
We prove comparison, uniqueness and existence results for viscosity solutions to a wide class of fully nonlinear second order partial differential equations F (x, u(x), du(x), du(x)) = 0 defined on a finite-dimensional Riemannian manifold M . Finest results (with hypothesis that require the function F to be degenerate elliptic, that is nonincreasing in the(More)
Nanoparticles engineered for biomedical applications are meant to be in contact with protein-rich physiological fluids. These proteins are usually adsorbed onto the nanoparticle's surface, forming a swaddling layer that has been described as a 'protein corona', the nature of which is expected to influence not only the physicochemical properties of the(More)
BACKGROUND Tobacco dependence management is a multi-component intervention that includes pharmacological treatments such as Nicotine Substitution Therapy (NST) or bupropion, and psychological therapy. There are some preliminary reports on topiramate efficacy for tobacco dependence. The aim of this study is to determine whether topiramate is as effective as(More)
PURPOSE It has been proposed in the literature that Fe(3)O(4) magnetic nanoparticles (MNPs) could be exploited to enhance or accelerate nerve regeneration and to provide guidance for regenerating axons. MNPs could create mechanical tension that stimulates the growth and elongation of axons. Particles suitable for this purpose should possess (1) high(More)

The impact of tipranavir plasma levels (TPV C(min)) on virological response was examined in 36 antiretroviral-experienced HIV-infected individuals. Although TPV C(min) did not predict outcome in patients with less than five or more than eight baseline TPV-associated resistance mutations, TPV C(min) values were greater in responders than in nonresponders(More)
There is a growing body of evidence indicating the importance of physical stimuli for neuronal growth and development. Specifically, results from published experimental studies indicate that forces, when carefully controlled, can modulate neuronal regeneration. Here, we validate a non-invasive approach for physical guidance of nerve regeneration based on(More)
Magnetic hyperthermia is a new type of cancer treatment designed for overcoming resistance to chemotherapy during the treatment of solid, inaccessible human tumors. The main challenge of this technology is increasing the local tumoral temperature with minimal side effects on the surrounding healthy tissue. This work consists of an in vitro study that(More)
