A close relationship between morphology and habitat is well documented for anoline lizards. To test the generality of this relationship in lizards, snout-vent, tail, and limb lengths of 18 species of Tropidurus (Tropiduridae) were measured and comparisons made between body proportions and substrate usage. Phylogenetic analysis of covariance by computer simulation suggests that the three species...

background: chronic wounds are a serious problem for the patient and can increase the socioeconomic burden on the healthcare system and community. this study aimed at investigating the effect of angioplasty on chronic ischemic wound healing. methods: this study was conducted in sina hospital, affiliated to tehran university of medical sciences. thirty-eight patients with chronic ischemic wounds...

background: venoplasty and stenting is a minimally invasive therapy that can be used for patients with deep venous insufficiency in the lower extremities. this study aimed at investigating the effect of venoplasty and venous stenting in patients with chronic venous insufficiency in the lower limbs. methods : this prospective case-series study recruited patients with chronic deep venous insuffic...

the goal of this study was to define the normal range of diameter in the deep vein of the lower limb and to compare this range with diameter of the veins with acute thrombosis and of veins with chronic thrombosis by using color doppler sonography. the study was cross sectional. the vein diameter and vein to artery ratio in different levels were measured and the following results were obtained. ...

objective(s): we investigated a frequency of lower extremity uptake on the radioactive iodine (rai) whole body scan (wbs) after rai treatment in patients with differentiated thyroid cancer, in order to retrospectively examine whether or not the frequency was pathological. methods: this retrospective study included 170 patients with thyroid cancer, undergoing rai treatment. overall, 99r (58%) an...

BACKGROUND Rice farming activities involve prolonged manual work and human-machine interaction. Prolonged farming risk-exposure may result in lower limb malalignment. This malalignment may increase the risk of lower extremity injury and physical disabilities. However, the prevalence and factors associated with lower extremity malalignment have not yet been reported. This study aimed to investig...

Locomotor muscles often perform diverse roles, functioning as motors that produce mechanical energy, struts that produce force and brakes that dissipate mechanical energy. In many vertebrate muscles, these functions are not mutually exclusive and a single muscle often performs a range of mechanically diverse tasks. This functional diversity has obscured the relationship between a muscle's locom...
