Retinal transplantation experiments have advanced considerably during recent years, but remaining diseased photoreceptor cells in the host retina physically obstruct the development of graft-host neuronal contacts which are required for vision. We here report selective removal of photoreceptors using the biodegradable elastomer poly(glycerol sebacate) (PGS). A 1x3 mm PGS membrane was implanted in
Abstract in UndeterminedThis study investigates humorous and self-mocking comments about age and age-related appearance among older gay, lesbian, bisexual, transsexual and queer advertisers in two Swedish Internet dating forums. Using a perspective where age is regarded as an accomplishment, humor was investigated as a way of relating to restrictive norms concerning age and sexuality. It was concl
Although there has been substantial research done on adsorption of metals/metalloids by Al (oxy)hydroxides, little is known regarding the adsorption of polyaromatic hydrocarbons (PAHs) on Al (oxy)hydroxides, especially those formed in the presence of organic acid. This paper investigated the adsorption of phenanthrene on Al (oxy)hydroxides formed with initial tannate/Al molar ratios (MRs) 0, 0.001
We report the 5 to 6 year follow-up of a multicenter study of bilateral subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) in advanced Parkinson's disease (PD) patients. Thirty-live STN patients and 16 GPi patienis were assessed at 5 to 6 years after DBS surgery. Primary outcome measure was the stimulation effect on the motor Unified Parkinson's Disease Ratin
Several strategic metals, elements and energy resources are about to run into scarcity in the near future under the present paradigm of use. A global systems model has been developed (WORLD) to assess the issue of scarcity and its implications for society. We show that scarcity may lead to “peak wealth”, “peak population”, “peak waste” and “peak civilization”, unless urgent counter-measures are sy
Most studies of the predictability of returns are based on time series data, and whenever panel data are used, the testing is almost always conducted in an unrestricted unitby- unit fashion, which makes for a very heavy parametrization of the model. On the other hand, the few panel tests that exist are too restrictive in the sense that they are based on homogeneity assumptions that might not be tr
A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t'(t) over bar' -> W(+)bW(-)(b) over bar. The search is based on 1.04 fb(-1) of proton-proton collisions at root s = 7 TeV collected by the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, chara
The pathogenesis of diabetic retinopathy (DR) remains unclear but hyperglycemia is an established risk factor. Endothelial dysfunction and changes in Ca(2+) signaling have been shown to precede the onset of DR. We recently demonstrated that high extracellular glucose activates the Ca(2+)/calcineurin-dependent transcription factor NFAT in cerebral arteries and aorta, promoting the expression of inf
Galectins are defined by a conserved beta-galactoside binding site, which has been linked to many of their important functions in e.g. cell adhesion, signaling and intracellular trafficking. Weak adjacent sites may enhance or decrease affinity for natural beta-galactoside containing glycoconjugates, but little is known about the biological role of this modulation of affinity (fine specificity). We
Photoinduced interaction of thioglycolic acid (TGA) capped CdTe quantum dots (QDs) with certain antioxidants such as estrogens and flavonoids has been investigated by using steady state and time resolved fluorescence spectroscopy. Reduction of electron-hole recombination has been observed (i.e., fluorescence quenching) while adding antioxidants to CdTe QDs. The Stern-Volmer constant (K-SV), quench
Niganda phichai Pellinen, sp. n., is described from northern Thailand. The new species is diagnosed and illustrated, including details of the genitalia and DNA sequencing. Variability in the male genitalia of Niganda radialis Gaede is reviewed, and notes are presented on the facies of female N. radialis
A comparative study of the central and southern parts of the Palaeoproterozoic Svecofennian orogen in the Baltic/Fennoscandian Shield and the platform area to the east and south of the Baltic Sea indicates that at least these parts of the orogen are built up of several NW-SE trending, 100-300 km wide tectonic megadomains separated from each other and complicated by major zones of mostly dextral sh
Back-arc volcanism in the western Argentinian provinces of Mendoza and Neuquen has been widespread from the Miocene to historic times. We present a detailed investigation of profiles through two of the major Miocene volcanic areas of the region, the neighboring Huantraico and La Matancilla plateaus, including new Ar-40/Ar-39 age results of major and trace elements as well as Nd, Sr and Pb isotopic
This manuscript presents the digital hardware realization of a wavelet based event detector for cardiac pacemaker applications. The architecture of the detector is partially folded to minimize hardware cost. An energy model is applied to evaluate the energy efficiency the sub-threshold (sub-VT ) domain. The design is synthesized in 65nm low leakage-high threshold CMOS technology, and it is shown t
The M-shell x-ray emission of highly charged tungsten ions has been investigated at the Livermore electron beam ion trap facility. Using the SuperEBIT electron beam ion trap and a NASA x-ray calorimeter array, transitions connecting to levels of the ground configurations in the 1500–3600 eV spectral range of zinc-like W44+ through cobalt-like W47+ have been measured. The measured spectra are compa
Abstract in UndeterminedUsing a sample of 7,260 university employees, we investigate how legitimacy, social and human capital influence the employees’ start-up propensity. We find that scientific legitimacy, as measured by the number of recently published peer reviewed scientific articles, and conference papers accepted had no significant effect. Scientific legitimacy measured as publications in n
Dyskinesias represent a major complication of dopamine replacement therapy in Parkinson's disease (PD) and have prompted a search for alternative treatments. The most radical advances in this field have been provided by surgical manipulations of the deep basal ganglia nuclei, and particularly by deep brain stimulation (DBS) of the subthalamic nucleus (STN). Although being very effective, high-freq
We describe two children with significant bleeding: one with multiple ecchymoses and the other with scrotal bleeding. In both patients, the activated partial thromboplastin time (APTT) was prolonged, with positivity for lupus anticoagulants (LA). However, the Owren prothrombin time (PT), usually insensitive for LA, was also prolonged. The presence of LA is associated with diverse clinical manifest
