1. Changes in muscle strength, vastus lateralis fibre characteristics and myosin heavy-chain (MyoHC) gene expression were examined in 48 men and women following 3 weeks of knee immobilization and after 12 weeks of retraining with 1866 eccentric, concentric or mixed contractions. 2. Immobilization reduced eccentric, concentric and isometric strength by 47 %.(More)
Cross-education enhances the performance of muscles not directly involved in the chronic conditioning of the muscles in a remote limb. Substantial cross-education occurs after training with eccentric contractions or with contractions evoked by electromyostimulation (EMS). Since during EMS and eccentric contractions, skin and muscle afferents are activated(More)
BACKGROUND Surveys still show a wide variation in routine use of deep vein thrombosis (DVT) prophylaxis despite its established place in current patient management. This article reviews the mechanism of action, efficacy and complications of stockings in preventing DVT. METHODS Relevant publications indexed in Medline (1966-1998) and the Cochrane database(More)
A scintillation glass-vial bioassay was used to test technical grade insecticides against the non-native stink bug Halyomorpha halys (Stål). Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is emerging as an important pest in the Mid-Atlantic States, especially in tree fruits and as a homeowner nuisance during the winter. Pyrethroid insecticides,(More)
Egg and nymphal development were studied under constant temperatures for the newly introduced pest species, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). Development was assessed at seven constant temperatures (15-35 degrees C). Development to adult was completed at temperatures between 17 and 33 degrees C, with egg hatch also occurring at 15 degrees(More)
BACKGROUND Compliance mismatch between native artery and prosthetic graft used for infrainguinal bypass is implicated in the aetiology of graft failure. The aim was to quantify the elastic properties of a new compliant poly(carbonate)polyurethane (CPU) vascular graft, and to compare the compliance properties of grafts made from CPU, expanded(More)
BACKGROUND Aedes (Stegomyia) albopictus (Skuse) is an important disease vector and biting nuisance. During the 2009 active season, six ∼1000-parcel sites were studied, three in urban and three in suburban areas of New Jersey, United States, to examine the efficacy of standard integrated urban mosquito control strategies applied area wide. Active source(More)
Identifying the origin of a biological invasion has important applications to the effective control of the invaders. This is more critical for invasive agricultural pests that cause severe economic losses. The brown marmorated stink bug, Halyomorpha halys, originally from East Asia, has become a principal agricultural pest in the US since its first(More)
Halyomorpha halys is an introduced stink bug species from Asia that is spreading throughout the Mid-Atlantic United States. It is native to South Korea, Japan, and eastern China, where it is an occasional pest of tree fruit, including apple and pear. Cage experiments with adults placed on apple and peach during critical plant growth stages demonstrate that(More)
The clinical characteristics and outcomes of children with mid-aortic syndrome (MAS) and the effectiveness of different therapeutic approaches in reducing hypertension are still debated. We conducted a single-centre retrospective review of the records of children with MAS over 30 years. Children with angiographic evidence of a narrowed abdominal aorta were(More)
