24,329,966 | Are home interventions effective at decreasing indoor nitrogen dioxide concentrations? | Nitrogen dioxide (NO2 ), a by-product of combustion produced by indoor gas appliances such as cooking stoves, is associated with respiratory symptoms in those with obstructive airways disease. We conducted a three-armed randomized trial to evaluate the efficacy of interventions aimed at reducing indoor NO2 concentratio... | Several combustion sources unique to the residential indoor environment, including gas stoves, produce nitrogen dioxide (NO2), and higher NO2 concentrations, are associated with worse respiratory morbidity in people with obstructive lung disease. A handful of studies have modified the indoor environment by replacing un... |
24,218,944 | Do [ Bulky DNA adducts in human sperm correlate with semen parameters and sperm apoptosis ]? | To explore the correlation of sperm polycyclic aromatic hydrocarbons (PAH)-DNA adducts with semen quality and sperm apoptosis. We collected semen samples from 433 infertile Chinese men, detected sperm PAH-DNA adducts using immunofluorescence staining and flow cytometry, and determined the rate of sperm apoptosis by TUN... | Sperm PAH-DNA adducts are evidently correlated with semen quality and sperm apoptosis, and play an important role in the evaluation of male productivity. |
25,923,658 | Does acute phase IL-10 plasma concentration associate with the high risk sources of cardiogenic stroke? | Etiological assessment of stroke is essential for accurate treatment decisions and for secondary prevention of recurrence. There is evidence that interleukin-10 (IL-10) associates with ischemic stroke. The aim of this prospective study was to assess the levels of IL-10 in ischemic stroke with unknown or suspected cardi... | IL-10 plasma concentration correlates independently with the number of EAE cardioembolic risk sources in patients with acute stroke. IL-10 may have potential to improve differential diagnostics of stroke with unknown etiology. |
18,392,924 | General and specific self-efficacy reports of patients with chronic low back pain: are they related to performances in a functional capacity evaluation? | The objective of this study was to analyze the relationship of general and specific self-efficacy (SE) beliefs with functional capacity evaluation (FCE) performances in patients with chronic non-specific low back pain (CLBP), while controlling for influence of gender, age, and self-reported pain intensity, self-esteem,... | The contribution of specific SE to the prediction of FCE performances is moderate in one instance, and insignificant in most instances (both specific and general SE). Because of the consistency of the differences between prediction (specific SE) and performances, and depending on the level of accuracy needed, future re... |
16,123,446 | Do iris-derived cells from adult rodents and primates adopt photoreceptor-specific phenotypes? | The purpose of this study was to investigate the effects of various genes related to photoreceptor development on rodent and primate iris cells and the potential of iris cells as donor cells for retinal transplantation. Adult rat and monkey iris tissue were cultured in serum-free medium containing basic fibroblast grow... | Adult iris-derived cultured cells of both rodents and primates expressed photoreceptor-specific phenotypes by inductions of transcription factors. These iris-derived photoreceptor-like cells have electrophysiological characteristics of rod photoreceptors. Furthermore, they can integrate in the developing retina under c... |
27,152,286 | Do effects of a Modified Hand Compression Bandage for Treatment of Post-Burn Hand Edemas? | To evaluate the effect of a modified hand compression bandage in patients with a post-burn hand edema. Patients were recruited from burn centers. We classified the patients into two groups: the modified hand compression bandage group comprising of 22 patients who had a modified hand compression bandage and received con... | The modified hand compression bandage will be clinically useful for the treatment of patients with post-burn hand edemas. |
25,987,031 | Is radiotherapy Alone Associated with Improved Outcomes Over Surgery in the Management of Solitary Plasmacytoma? | A moderate dose of radiation is the recommended treatment for solitary plasmacytoma (SP), but there is controversy over the role of surgery. Our study aimed at comparing different treatment modalities in the management of SP. Data from 38 consecutive patients with solitary plasmacytoma, including 16 with bone plasmacyt... | Radiotherapy alone can be considered as a more effective treatment for SP over surgery. Whether a combination of radiotherapy and surgery improves outcomes requires further study. |
7,637,663 | Is [ Goiter incidence in Germany greater than previously suspected ]? | The data regarding goitre prevalence in Germany is based on calculation arising out of dissimilar studies conducted among inhomogeneous study groups. The aim of our study was to collect data towards prevalence of goitre, thyroid size and structure through a prospective nationwide survey conducted using identical examin... | The prevalence of goitre in Germany is higher than it has been reported. The study underlines the insufficiency of the present goitre prophylaxis. Only an iodine prophylaxis (table salt, food products, fodder) backed by legislative measures can bring about a real breakthrough. |
20,196,712 | Risk-adjusted continuous outcome monitoring with an EWMA chart: could it have detected excess mortality among intensive care patients at Bundaberg Base Hospital? | To test whether applying a continuous riskadjusted charting method, using an exponentially weighted moving average (EWMA) chart, would have been useful for monitoring outcomes of patients admitted to the intensive care unit at Bundaberg Base Hospital, Queensland, between November 2000 and December 2005. An EWMA chart w... | Continuous monitoring of outcomes using an EWMA chart may have advantages over other techniques. Had data been available, analysis with an EWMA chart might have prompted review of processes and outcomes among patients at Bundaberg Base Hospital ICU. |
