The balsam woolly adelgid (Adelges piceae (Ratzeburg) (Homoptera: Adelgidae)) (BWA) is a nonnative, invasive insect that threatens Abies species throughout North America. It is well established in the Pacific Northwest, but continues to move eastward through Idaho and into Montana and potentially threatens subalpine fir to the south in the central and southern Rocky Mountains. We developed a climatic risk model and map that predicts BWA impacts to subalpine fir using a two-step process. Using 30-year monthly climate normals from sites with quantitatively derived BWA damage severity index values, we built a regression model that significantly explained insect damage...

Return to work (RTW) for people with acquired brain injury (ABI) represents a main objective of rehabilitation: this work presents a strong correlation between personal well-being and quality of life. The aim of this study is to investigate the prognostic factors that can predict RTW after ABI (traumatic or non- traumatic aetiology) in patients without disorders of consciousness (e.g. coma, vegetative or minimally conscious state) at the beginning of their admission to rehabilitation. At the end of a 6-month follow-up after discharge, data were successfully collected in 69 patients...

Although the true incidence of postoperative dysphagia after cardiac surgery is unknown, it has been reported to occur in 3 to 21.6 per cent of patients. Historically, dysphagia has been associated with increased surgical complications and prolonged hospital stay. This study aimed to evaluate the costs and outcomes associated with dysphagia after cardiac surgery. Patients undergoing nonemergent, nontransplant cardiac operations between June 2013 and June 2014 were eligible for inclusion. Independent predictors of cost were identified through a multivariate linear regression model...

We treated 2 patients with progressive, refractory scleroderma with a combined immunotherapy approach using plasmapheresis followed by rituximab and then intravenous umbilical-cord-derived allogeneic mesenchymal stem cells (MSCs). Both patients improved subjectively and objectively for over a year. Upon recurrence of their symptoms, the patients were treated again with allogeneic MSCs alone with a very good response. The combination was well tolerated and effective suggesting a large scale study may be warranted in progressive, refractory Scleroderma...

During a further and comprehensive phytochemical investigation on the shed trunk barks of the critically endangered plant Abies beshanzuensis, one new (1) and ten known (2-11) lignans with diverse structures were isolated. On the basis of spectroscopic methods, the new structure was established to be (7S,8R,8'R)-4'-methoxyl-α-conidendrin (1). Among the isolated lignans, (-)-matairesinol (5) and (-)-arctigenin (6) showed significant anti-neuroinflammatory activities by inhibiting the overproduction of nitric oxide in lipopolysaccharide-stimulated murine BV-2 microglial cells, with IC50 values of 11...

Proton pump inhibitors (PPIs) have a negative impact on bone accrual. Because osseointegration is influenced by bone metabolism, this study investigates the association between PPIs and the risk of osseointegrated implant failure. This retrospective cohort study included a total of 1,773 osseointegrated dental implants in 799 patients (133 implants in 58 PPIs users and 1,640 in 741 non-users) who were treated at the East Coast Oral Surgery Clinic in Moncton, Canada, from January 2007 to September 2015. Kaplan-Meier estimator was used to describe the hazard function of dental implant failure by PPIs usage...

BACKGROUND: Laparoscopic surgery offers patients with rectal cancer short-term benefits and similar survival rates as open surgery. However, selecting patients who are suitable candidates for laparoscopic surgery is essential to prevent intra-operative conversion from laparoscopic to open surgery. Clinical and pathological variables were studied among patients who had converted laparoscopic surgeries within the COLOR II trial to improve patient selection for laparoscopic rectal cancer surgery...

Thoracic endovascular aortic repair (TEVAR) is recognized as an attractive option to treat complicated Type B aortic dissection. Nevertheless, TEVAR is not always technically possible. We report the case of a 53-year-old male with complicated Type B aortic dissection, in the setting of a complex anomalous aortic arch anatomy with an aneurysmal aberrant right subclavian artery. He was successfully treated by the frozen elephant trunk technique using the Thoraflex hybrid graft.

In peripheral arterial disease (PAD) of the lower extremities, the presence of flow-limiting stenoses can be objectively detected by the ankle-brachial index (ABI). However, the severity of ischemic symptoms is not necessarily associated with the ABI value. Atherosclerotic plaque in lower extremity PAD induces ankle arterial stiffness and reduces ankle vascular resistance, which may decrease ankle blood flow and cause ischemic symptoms. We hypothesized that the ankle hemodynamic index (AHI), defined as the ratio of ankle arterial stiffness to ankle vascular resistance, could be used to assess the blood supply deficiency in a diseased lower limb in patients with PAD...

BACKGROUND: Silver fir trunk extract (SFTE) is a complex mixture of antioxidative polyphenols (lignans and phenolic acids) from the trunks of silver fir trees (Abies alba, lignum). In our previous study, we have shown that SFTE exerts strong antioxidative and protective effects against atherogenic, diet-induced arterial wall damage. OBJECTIVE: The aim of the present study was to test the potential protective effects of SFTE and its compounds, two phenolic acids (p-coumaric and protocatechuic acids) in ischemia-reperfusion injury of isolated rat hearts...

Diversity patterns and dynamics at forest edges are not well understood. We disentangle the relative importance of edge-effect variables on spatio-temporal patterns in species richness and occupancy of deadwood-dwelling fungi in fragmented old-growth forests. We related richness and log occupancy by 10 old-growth forest indicator fungi and by two common fungi to log conditions in natural and anthropogenic edge habitats of 31 old-growth Picea abies forest stands in central Sweden. We compared edge-to-interior gradients (100 m) to the forest interior (beyond 100 m), and we analyzed stand-level changes after 10 yr...

Tree mortality is a key process shaping forest dynamics. Thus, there is a growing need for indicators of the likelihood of tree death. During the last decades, an increasing number of tree-ring based studies have aimed to derive growth-mortality functions, mostly using logistic models. The results of these studies, however, are difficult to compare and synthesize due to the diversity of approaches used for the sampling strategy (number and characteristics of alive and death observations), the type of explanatory growth variables included (level, trend, etc...
