The determination of apparent nutrient digestibility and availability coefficients (ADC and AAC) of ingredients is an important process in the formulation of cost efficient diets for fish. Collection of feces by repeated manual stripping is commonly practiced. However, due to the stress and possible physical damage imposed on fish during repeated stripping, this practice may influence ADC and A...
We extend a semiclassical model of transfer reactions to the case in which one of the collision partners is a vibrational nucleus. The model is applied to oneand two-proton stripping reactions in the Cl + Mo system, for which a rapid transition from normal to anomalous slope in the two proton transfer reaction at energies around the Coulomb barrier is experimentally observed. This behavior is s...
Following peripheral axotomy, the presynaptic terminals are removed from lesioned neurons, that is synaptic stripping. To elucidate involvement of astrocytes and microglia in synaptic stripping, we herein examined the motoneuron perineuronal circumference after hypoglossal nerve transection. As reported previously, axotomy-induced slow cell death occurred in C57BL/6 mice but not in Wistar rats....
An electrochemical anodic stripping procedure for ultra-trace assay of xanthine in Cu2þ solution at a glassy carbon electrode (GCE) is described. Cyclic voltammetry was used to characterize the nature of the process taking place at the GCE. The anodic stripping response in the presence of Cu2þ, at 150 mV (peak I) and 600 mV (peak II), is evaluated with respect to various experimental and instru...
BACKGROUND Epicutaneous immunotherapy targets the network of dendritic cells in the epidermis. Allergen exposure of the dermal layers should be limited as these contain mast cells and blood vessels, which increases the risk for local and systemic allergic reactions. METHODS This intraindividually controlled trial included 20 subjects with birch pollen allergy. Three areas of the volar forearm...
Genetic switches based on the [Formula: see text] system are master regulators of an array of cellular responses. Recent kinetic experiments have shown that [Formula: see text] can actively remove NF-κB bound to its genetic sites via a process called "molecular stripping." This allows the [Formula: see text] switch to function under kinetic control rather than the thermodynamic control contempl...
A novel, sensitive electrochemical immunoassay has been developed based on the precipitation of silver on colloidal gold labels which, after silver metal dissolution in an acidic solution, was indirectly determined by anodic stripping voltammetry (ASV) at a glassy-carbon electrode. The method was evaluated for a noncompetitive heterogeneous immunoassay of an immunoglobulin G (IgG) as a model. T...
The object of the present study was to investigate the effect of membrane stripping at term pregnancy on the duration of pregnancy and labor induction and its complication. Therefore, a randomized trial of membrane stripping at term pregnancy versus vaginal examination alone was performed. In this study 101 patients with 39 completed weeks pregnancy were selected. All the patients, ...
We discuss the voltammetric methods that are used to assess metal-organic complexation in seawater. These consist of titration methods using anodic stripping voltammetry (ASV) and cathodic stripping voltammetry competitive ligand experiments (CSV-CLE). These approaches and a kinetic approach using CSV-CLE give similar information on the amount of excess ligand to metal in a sample and the condi...
BACKGROUND Laparoscopic surgery has become the gold-standard treatment for ovarian endometriomas. The objective of this trial was to evaluate different procedures for the laparoscopic excision of ovarian endometriomas with the stripping technique. METHODS Forty-eight patients with ovarian endometrioma were enrolled in two consecutive independent randomized trials. Two different techniques wer...
