Amantadine hydrochloride is one of the most commonly prescribed medications for patients with prolonged disorders of consciousness after traumatic brain injury. Preliminary studies have suggested that amantadine may promote functional recovery. We enrolled 184 patients who were in a vegetative or minimally conscious state 4 to 16 weeks after traumatic ...

By exploiting recent developments associated with parity-time (PT) symmetry in optics, we here propose a new avenue in realizing single-mode large area laser amplifiers. This can be accomplished by utilizing the abrupt symmetry breaking transition that allows the fundamental mode to experience gain while keeping all the higher order modes ...

Malignant mixed Müllerian tumor (MMMT) is a rare neoplasm of the female genital system. A case of MMMT in the uterus of an 8-year-old female dwarf rabbit, which died with clinical signs associated with severe acute dyspnea and anorexia, is described. At necropsy, an oval, firm tumor was found in ...

We demonstrate that published vectorial laws of reflection and refraction of light based solely on the cross product do not, in general, uniquely determine the direction of the reflected and refracted waves without additional information. This is because the cross product does not have a unique inverse operation, which is ...

We present an optical system that performs Stokes polarimetric imaging with a single-pixel detector. This fact is possible by applying the theory of compressive sampling to the data acquired by a commercial polarimeter without spatial resolution. The measurement process is governed by a spatial light modulator, which sequentially generates a ...

High-grade brain tumors are heterogeneous with respect to the composition of bona fide tumor cells and with respect to a range of intermingling parenchymal cells. Glioblastomas harbor multiple cell types, some with increased tumorigenicity and stem cell-like capacity. The stem-like cells maybe the cells of origin for tumor relapse. However, ...

We report femtosecond pulses from a passive C-band two-section AlGaInAs/InP mode-locked laser with a monolithically integrated passive waveguide made by quantum well intermixing. Without any external pulse compression, Lorentzian pulses are generated at a repetition frequency of ∼38  GHz with 490 fs pulse duration, which is, to the best of our ...

Beginning with this issue of Acta Dermato-Venereologica, the Editorial Board has decided to launch a series of theme issues, whereby regular papers on similar topics are published together instead of appearing chronologically (and hence dispersed) based solely on the date of acceptance. Needless to say, these themes, just as in ...

The growing interest in the role of stochasticity in biochemical systems drives the demand for tools to analyse stochastic dynamical models of chemical reactions. One powerful tool to elucidate performance of dynamical systems is sensitivity analysis. Traditionally, however, the concept of sensitivity has mainly been applied to deterministic systems, and ...

A novel adenovirus was identified in a cotton-top tamarin (Saguinus oedipus) with diarrhea by negative-staining electron microscopy of feces, consensus polymerase chain reaction, and sequencing. Partial sequences were obtained from the DNA-dependent DNA polymerase, the p52k gene, and the hexon. Bayesian and maximum likelihood phylogenetic analyses indicated that the virus ...

We describe an adaptive coded-aperture imager operating in the midwave IR. This consists of a coded-aperture mask, a set of optics, and a 4k×4k focal plane array (FPA). This system can produce images with a resolution better than the detector pixel limit by combining multiple frames of data recorded with ...

The idea of superresolving pupil filters comes from the concept of superoscillations that may occur in regions of a band-limited signal with small amplitude having oscillations faster than the fastest Fourier component of the signal. In optical microscopy, superresolution can be achieved by appropriate design of pupil functions where the ...

The most definitive role of fluorodeoxyglucose (FDG)-PET/computed tomography (CT) at present is surveillance and detecting recurrence in patients who have completed primary therapy but demonstrate a rising serum tumor marker (e.g., CA-125 levels). In this scenario, PET/CT demonstrates high sensitivity and accuracy in detecting lesions that are otherwise challenging, and ...

Immune recognition and rejection of tissues expressing transfected genes is a major complication of gene replacement therapy for inherited genetic disorders. Owing to the high immunogenicity of human bullous pemphigoid antigen 2 (hBPAG2), the induction and maintenance of tolerance to this neo-antigen is essential to deliver the gene product to ...

Although it is assumed that hemodynamic responders to pharmacological therapy after a variceal hemorrhage are adequately protected from rebleeding, there is no evidence that either this response or its protective effect extend beyond the usual 2-year follow-up featured in available studies. We aimed to assess the maintenance of hemodynamic response ...
