Hypogonadism Risk in Men Treated for Childhood Cancer.

Context: Pediatric cancer treatment may imply an increased risk of hypogonadism, leading to metabolic disorders and osteoporosis. Such complications are potentially preventable. Objective: The aim of this study was to assess diagnosis- and treatment-dependent risk of hypogonadism in male childhood cancer survivors (CCS). Design: Male CCS who were treated during the period 1970-2002 and who in 2004

The use of a rigid disc to protect exposed structures in wounds treated with negative pressure wound therapy: Effects on wound bed pressure and microvascular blood flow.

There are increasing reports of deaths and serious complications associated with the use of negative pressure wound therapy (NPWT). Bleeding may occur in patients when NPWT is applied to a wound with exposed blood vessels or vascular grafts, possibly due to mechanical deformation and hypoperfusion of the vessel walls. Recent evidence suggests that using a rigid barrier disc to protect underlying t

Translocation of GluR1-containing AMPA receptors to a spinal nociceptive synapse during acute noxious stimulation.

Potentiation of spinal nociceptive transmission by synaptic delivery of AMPA receptors, via an NMDA receptor- and Ca(2+)/calmodulin-dependent protein kinase II (CaMKII)-dependent pathway, has been proposed to underlie certain forms of hyperalgesia, the enhanced pain sensitivity that may accompany inflammation or tissue injury. However, the specific synaptic populations that may be subject to such

Radiative-lifetime and Lande-factor Measurements of the Se-i 4p(3)5s (5)s(2) Level Using Pulsed Laser Spectroscopy

First laser spectroscopic investigations on atomic selenium are reported. Natural selenium was thermally dissociated in a quartz resonance cell keeping the background pressure of abundant selenium molecules low by differential heating. The 4p35s5S2 level was excited by frequency-tripled pulsed-dye laser radiation at 207 nm. From time-resolved recordings of the fluorescence decay at 216 nm a natura

Fear of falling and falls in people with Parkinson's disease treated with deep brain stimulation in the subthalamic nuclei.

Nilsson MH, Rehncrona S, Jarnlo G-B. Fear of falling and falls in people with Parkinson's disease treated with deep brain stimulation in the subthalamic nuclei. Acta Neurol Scand: 2011: 123: 424-429. © 2010 John Wiley & Sons A/S. Background - No previous study prospectively investigated the effects of subthalamic deep brain stimulation on fear of falling (FOF) and falls. Aim - The aim was to p

Multifunctional Gold Nanorods with Ultrahigh Stability and Tunability for In Vivo Fluorescence Imaging, SERS Detection, and Photodynamic Therapy.

Multimodal: Gold nanorods are coated with silica/polymer mutilayers, doped with surface-enhance Raman scattering (SERS) and fluorescence agents as well as photosensitizers. The structural and optical properties are tunable and stable in solutions and in living bodies. A real-time and specific in vivo SERS and fluorescence detection method using this structure is applied for tumor detection and sub

On the Choice of Sampling Rates in Parametric Identification of Time Series

Aliasing gives a lower bound for the sampling rate in ordinary spectral analysis of a time series. In parametric it appears at first sight that no such limitations are present. In this note we will obtain insight into this paradox by analyzing a simple Gauss-Markov process. We assume that a time series analysis is performed based on N samples of the series at equal spacing h. The result shows that

Swedish ambulance services 1935-1936 of Gunnar Agge

The fact that Sweden has been spared from war on its soil for almost 200 years, has not stopped Swedish citizens from participating in conflicts worldwide during this period. This has been described, especially from the soldiers perspective. The contribution of Swedish physicians has not been written about to the same extent. When Mussolini's Italy in October 1935 invaded the poor and underdevelop

Functional integration of grafted neural stem cell-derived dopaminergic neurons monitored by optogenetics in an in vitro Parkinson model.

Intrastriatal grafts of stem cell-derived dopamine (DA) neurons induce behavioral recovery in animal models of Parkinson's disease (PD), but how they functionally integrate in host neural circuitries is poorly understood. Here, Wnt5a-overexpressing neural stem cells derived from embryonic ventral mesencephalon of tyrosine hydroxylase-GFP transgenic mice were expanded as neurospheres and transplant

Allelic variants of streptokinase from Streptococcus pyogenes display functional differences in plasminogen activation.

A common mammalian defense mechanism employed to prevent systemic dissemination of invasive bacteria involves occlusion of local microvasculature and encapsulation of bacteria within fibrin networks. Acquisition of plasmin activity at the bacterial cell surface circumvents this defense mechanism, allowing invasive disease initiation. To facilitate this process, S. pyogenes secretes streptokinase,

Utility of Intra-operative Cone Beam Computed Tomography in Endovascular Treatment of Aorto-iliac Occlusive Disease.

Endovascular treatment of aorto-iliac occlusive disease (AIOD) is well established, but to maintain long-term patency, secondary interventions are common. Multiple stents and iliac artery tortuosity often make it difficult to evaluate stent compression intra-operatively and this might be a cause for later failure. Completion angiography (CA) and pressure gradient (PG) measurement are often used to
