Humans and birds both walk and run bipedally on compliant legs. However, differences in leg architecture may result in species-specific leg control strategies as indicated by the observed gait patterns. In this work, control strategies for stable running are derived based on a conceptual model and compared with experimental data on running humans and pheasants (Phasianus colchicus). From a mode...

Campylobacter jejuni is the major human food-borne pathogen. Its bipolar flagella are heavily O-glycosylated with microbial sialic acids and essential for its motility pathogenicity. However, both glycosylation of exact contribution legionaminic acid (Leg) to flagellar activity poorly understood. Herein, we report development a metabolic labeling method Leg on bacterial probes based azide-modif...

Gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. In this paper, a new robotic orthosis is presented for treadmill training. In the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are conside...

Black leg has been reported in a variety of animals, but is ofthe most importance in cattle and sheep. A20 days old Holsteindairy calf was examined because of anorexia and lameness from2 days ago. The calf was depressed, tachypneic, tachycardic, andhad a body temperature of 38.5ºC. Both hind limbs proximal tothe tarsal joint were markedly swollen, firm and painful. Nocrepitation was noted on pa...

restless leg syndrome (rls) is a common cause of painful legs. the leg pain of restless leg syndrome typically eases with motion of the legs and becomes more noticeable at rest. stress or emotional upset can make symptoms worse. the purpose of the present study was to examine the relationship of emotional disturbance and quality of life to the severity of rls. using a descriptive-correlational ...

Background: Post-activation potentiation refers to the acute and temporary enhancement of performance in explosive movements after performing a conditioning activity, such as plyometrics. The current study aimed investigate effects horizontal leg bounding on 30 m acceleration performance, 5 split times, sprint kinematics (step frequency length, flight contact time). Methods: Fourteen young spri...

We describe a case of intramuscular vascular malformation with extensive ossification within the posterior compartment muscles of leg which grossly mimicked long bone leading to equinus deformity of foot. Phleboliths and calcifications are characteristic of vascular malformations, while massive ossification is rare. To our knowledge, no extensive ossified vascular malformation within the leg mu...
