Versatile Dynamic Motion Generation Framework: Demonstration With a Crutch-Less Exoskeleton on Real-Life Obstacles at the Cybathlon 2020 With a Complete Paraplegic Person.

Lower-limb exoskeletons are a promising option to increase the mobility of persons with leg impairments in a near future. However, it is still challenging for them to ensure the necessary stability and agility to face obstacles, particularly the variety that makes the urban environment. That is why most of the lower-limb exoskeletons must be used with crutches: the stability and agility features are deferred to the patient.

#Globalhealth Twitter Conversations on #Malaria, #HIV, #TB, #NCDS, and #NTDS: a Cross-Sectional Analysis.

Background: Advocates use the hashtag #GlobalHealth on Twitter to draw users' attention to prominent themes on global health, to harness their support, and to advocate for change.

Objectives: We aimed to describe #GlobalHealth tweets pertinent to given major health issues.

Methods: Tweets containing the hashtag #GlobalHealth (N = 157,951) from January 1, 2014, to April 30, 2015, were purchased from GNIP Inc.

Triploid grass carp susceptibility and potential for disease transfer when used to control aquatic vegetation in reservoirs with avian vacuolar myelinopathy.

Avian vacuolar myelinopathy (AVM) is an often-lethal neurologic disease that affects waterbirds and their avian predators (i.e., bald eagles Haliaeetus leucocephalus) in the southern United States.

Determination of an oral aflatoxin dose that acutely impairs hepatic function in domestic pigeons (Columba livia).

Aflatoxin B1 is a common hepatotoxin in birds. The goal of this study was to establish an acute model for hepatotoxicosis and decreased hepatic function in the white Carneaux pigeon (Columba livia) via oral administration of this mycotoxin. Aflatoxin B1 was orally administered at a dose of 3 mg/kg dissolved in dimethyl sulfoxide to 3 groups of pigeons every 24 hours for 2, 4, and 6 consecutive days, respectively.

Comparison of testis structure, function and thyroid hormone levels in control C57BL/6 mice and anti-mullerian hormone over expressing mice.

Anti-Mullerian hormone (AMH) is considered as a negative regulator of postnatal Leydig cell (LC) differentiation, because AMH over expressing mice (Mt-hAMH mice) testes are deficient in LC. Therefore, in the present study Mt-hAMH mice was used as a model to examine the process of postnatal LC differentiation. Testis structure-function studies were performed in age-matching Mt-hAMH and C57BL/6 (controls) mice; testicular components were quantified and circulating testosterone and thyroid hormone levels (thyroxine/T4 and triiodothyronine/T3; necessary for postnatal LC differentiation) were determined.
