Most studies assessing vegetation response following control of invasive Tamarix trees along southwestern U.S. rivers have been small in scale (e.g., river reach), or at a regional scale but with poor spatial-temporal replication, and most have not included testing the effects of a now widely-used biological control. We monitored plant composition following Tamarix control along hydrologic, soil and climatic gradients in 244 treated and 172 reference sites across six U.S. States. This represents the largest comprehensive assessment to date on the vegetation response to the four most common Tamarix control treatments...

Herbicide drift may have unintended impacts on native vegetation, adversely affecting individual species and plant communities. To determine potential ecological effects of herbicide drift, small plant community plots were constructed using nine perennial species found in different Willamette Valley Oregon grassland habitats. Studies were conducted at two Oregon State University farms in two separate years, with single and combined treatments of 0.01 to 0.2 x field application rates (f.a.r.) of 1119 g ha(-1) for glyphosate [active ingredient (a...

Polysomnographic recording of night sleep was carried out in 15 patients with the diagnosis vegetative state (syn. unresponsive wakefulness syndrome). Sleep scoring was performed by three raters, and confirmed by means of a spectral power analysis of the electroencephalogram, electrooculogram and electromyogram. All patients but one exhibited at least some signs of sleep. In particular, sleep stage N1 was found in 13 patients, N2 in 14 patients, N3 in nine patients, and rapid eye movement sleep in 10 patients...

Given the importance of suspended sediment to biogeochemical functioning of aquatic ecosystems, and the increasing concern of mixed-land-use effects on pollutant loading, there is an urgent need for research that quantitatively characterizes spatiotemporal variation of suspended sediment dynamics in contemporary watersheds. A study was conducted in a representative watershed of the central United States utilizing a nested-scale experimental watershed design, including five gauging sites (n=5) partitioning the catchment into five sub-watersheds...

Medial prefrontal cortex (mPFC) is usually known for participating in virtually all self related processing. However, few have investigated the role of mPFC in modulating conscious awareness. This study aimed to depict the relationship between the mPFC connectivity and the severity and outcome of the disorders of consciousness (DOC) among patients with acquired brain injury. Thirty-four patients with DOC (17 in a minimally conscious state and 17 in an unresponsive wakefulness syndrome/vegetative state) and 11 healthy controls were recruited, underwent clinical assessment and resting-state functional MRI scan, and were further followed up to evaluate recovery outcome using the Glasgow Outcome Scale...

A multiyear interagency Listeria monocytogenes Market Basket Survey was undertaken for selected refrigerated ready-to-eat foods purchased at retail in four FoodNet sites in the United States. Food samples from 16 food categories in six broad groups (seafood, produce, dairy, meat, eggs, and combination foods) were collected weekly at large national chain supermarkets and independent grocery stores in California, Maryland, Connecticut, and Georgia for 100 weeks between December 2010 and March 2013. Of the 27,389 total samples, 116 samples tested positive by the BAX PCR system for L...

Shallow lakes can switch suddenly from a turbid situation with high concentrations of phytoplankton and other suspended solids to a vegetated state with clear water, and vice versa. These alternative stable states may have a substantial impact on the fate of hydrophobic organic compounds (HOCs). Models that are fit to simulate impacts from these complex interactions are scarce. We developed a contaminant fate model which is linked to an ecosystem model (PCLake) for shallow lakes. This integrated model was successful in simulating long-term dynamics (1953-2012) of representative polycyclic aromatic hydrocarbons (PAHs) in the main biotic and abiotic components in a large shallow lake (Chaohu in China), which has undergone regime shifts in this period...

Recurrent respiratory papillomatosis (RRP) is a benign disease of the upper aero-digestive tract caused by human papillomavirus (HPV) infection, which affects children and young adults. The aim of this review is to describe the main etiological, epidemiological, clinical, diagnostic, and treatment aspects of RRP. Most infections in children occur at birth, during passage through the birth canals of contaminated mothers. In adults, HPV is transmitted sexually. Papillomas usually appear as exophytic nodules, primarily in the larynx, but occasionally involving the nasopharynx, tracheobronchial tree, and pulmonary parenchyma...

The aim of this study is to evaluate mood disorders and needs in caregivers of disorders of consciousness (DOC) patients during the admission to Neurorehabilitation Unit. A total of 80 caregivers was enrolled and divided in two groups (caregivers of vegetative state-VS patients and caregivers of minimally conscious state-MCS patients). Paired sample t tests were carried out to test differences between baseline observation (T0) and after 6 months (T1). Caregivers of VS patients showed an improvement between T0 and T1 especially, in vitality, mean health, Beck Depression Inventory (BDI-II), Spielberger State-Trait Anxiety Inventory-Y (STAI-Y), Prolonged Grief Disorder (PG 12) and Caregiver Needs Assessment (CNA)...

The annual growth cycle of trees is the result of seasonal cues. The onset of winter triggers an endodormant state preventing bud growth and, once a chilling requirement is satisfied, these buds enter an ecodormant state and resume growing. MADS-box genes with similarity to Arabidopsis SHORT VEGETATIVE PHASE (SVP) [the SVP-like and DORMANCY ASSOCIATED MADS-BOX (DAM) genes] have been implicated in regulating flowering and growth-dormancy cycles in perennials. Here, we identified and characterized three DAM-like (MdDAMs) and two SHORT VEGETATIVE PHASE-like (MdSVPs) genes from apple (Malus × domestica 'Royal Gala')...

Over the last 25 years there have been a number of papers highlighting the issues of high rates of misdiagnosis in prolonged disorders of consciousness (PDOC) (Andrews, K., Murphy, L., Munday, R., & Littlewood, C. (1996). Misdiagnosis of the vegetative state: Retrospective study in a rehabilitation unit. BMJ, 313(7048), 13-16; Childs, N. L., Mercer, W. N., & Childs, H. W. (1993). Accuracy of diagnosis of persistent vegetative state. Neurology, 43(8), 1465-1467). Surprisingly, these rates still remain at the same level despite defined criteria for diagnosis (Schnakers, C...

Significant increases in remotely sensed vegetation indices in the northern latitudes since the 1980s have been detected and attributed at annual and growing season scales. However, we presently lack a systematic understanding of how vegetation responds to asymmetric seasonal environmental changes. In this study, we first investigated trends in the seasonal mean leaf area index (LAI) at northern latitudes (north of 30°N) between 1982 and 2009 using three remotely sensed long-term LAI data sets. The most significant LAI increases occurred in summer (0...

Several community level measures of healthy food access exist, but evaluation efforts have been limited leaving uncertainty about how to prioritize communities for intervention. This study aimed to assess several existing measures to inform statewide public health planning efforts in New Jersey, USA. We assessed agreement between community measures of healthy food access and then evaluated the predictive validity of each measure by describing its association with complete fruit and vegetable cash-value voucher redemption (proportion redeemed ≥70, ≥80, ≥90%) among 30,078 low-income households participating in the New Jersey Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) during 2013-2014...
