Blood pressure is commonly measured in veterinary medicine. Previous studies have used indirect measurements to compare the forelimb and hindlimb blood pressure in dogs, and yielded contradictory results. Notably in these studies, the measurement of both limbs was not performed simultaneously. In this study, Doppler ultrasonography was used to measure systolic arterial pressure (SAP) and pulse rate (PR) simultaneously on the median palmar artery of forelimb and the medial plantar artery of hindlimb in 108 conscious dogs. The optimal cuff size was selected using 30-40% of the limb circumference. The SAP of forelimb and hindlimb were 149.5 ± 28.5 mm Hg and 152.3 ± 31.1 mm Hg. The PR of forelimb and hindlimb were 113.9 ± 31.7 beats per minute (bpm) and 113.1 ± 31.2 bpm, respectively. The SAP and PR of the forelimb and hindlimb correlated significantly (Pearson R = 0.696, P < .001; Pearson R = 0.966, P < .001). There was no significant difference in SAP and PR between the forelimb and hindlimb (P = .1; P = .184). There was no significant difference in the SAP and PR of the forelimb and hindlimb using Doppler device measurement in conscious dogs. Both sites of blood pressure measurement could be adequate for analyzing trends in blood pressure.

Differences in habitat use impose ecological constraints which in turn lead to functional and morphological differences through adaptation. In fact, a convergent evolutionary pattern is evident when species exhibit similar responses to similar environments. In this study we examine how habitat use influences the evolution of body shape in lizards from the family Lacertidae.

Gibbons, a type of lesser ape, are brachiators but also walk bipedally and without forelimb assistance, not only on the ground but also on tree branches. The arboreal bipedal walking strategy of the gibbons has been studied in previous studies in relation to two-dimensional (2D) kinematic analysis. However, because tree branches and the ground differ greatly in width, leading to a constrained foot contact point on the tree branches, gibbons must adjust their 3D joint motions of trunk and hindlimb on the tree branches.

The transgenic SOD1G93A mouse model is the most widely used animal model of amyotrophic lateral sclerosis (ALS), a fatal disease of motor neuron degeneration. While genetic background influences onset and progression variability of motor dysfunction, the C57BL/6 background most reliably exhibits robust ALS phenotypes; thus, it is the most widely used strain in mechanistic studies. In this model, paresis begins in the hindlimbs and spreads rostrally to the forelimbs.

The aim of this study was to evaluate the efficacy of thermography in assessing the impact of regular physical effort on changes in the body surface temperature of the upper body parts of young racehorses. The study involved monitoring 33 racehorses aged 3 years in 3 imaging sessions over a period of 3 months. Temperature measurements of the neck and upper part of the forelimbs and hindlimbs from both sides were taken just before and after training.

5'Hox genes regulate pattern formation along the axes of the limb. Previously, we showed that Hoxa13/Hoxd13 double-mutant newts lacked all digits of the forelimbs during development and regeneration, showing that newt Hox13 is necessary for digit formation in development and regeneration. In addition, we found another unique phenotype.
