Circumpolar Population Structure, Diversity and Recent Evolutionary History of the Bearded Seal in Relation to Past and Present Icescapes.

The Arctic environment plays a critical role in the global climate system and marine biodiversity. The region's ice-covered expanses provide essential breeding and feeding grounds for a diverse assemblage of marine species, who have adapted to thrive in these harsh conditions and consequently are under threat from global warming. The bearded seal (Erignathus barbatus), including two subspecies (E.

The Teitge test.

Introduction: High tibial osteotomy (HTO) is used to treat medial knee osteoarthritis (OA). A simple clinical test to select the patients most likely to benefit from the procedure was suggested by R. A.

The effect of temperature constraints on the treatment of tumors using focused ultrasound-induced acoustic streaming.

The transport of drugs into tumor cells near the center of the tumor is known to be severely hindered due to the high interstitial pressure and poor vascularization. The aim of this work is to investigate the possibility to induce acoustic streaming in a tumor. Two tumor cases (breast and abdomen) are simulated to find the acoustic streaming and temperature rise, while varying the focused ultrasound transducer radius, frequency, and power for a constant duty cycle (1%).

Application of EMG feedback for hand prosthesis control in high-level amputation: a case study.

EMG feedback improves force control of a myoelectric hand prosthesis by conveying the magnitude of the myoelectric signal back to the users via tactile stimulation. The present study aimed to test if this method can be used by a participant with a high-level amputation, and whose muscle used for prosthesis control (pectoralis major) was not intuitively related to hand function. Vibrotactile feedback was delivered to the participant's torso, while the control was tested using EMG from three different muscles.

An Atypical Presentation of Osseous Choristoma in a 63-Year-Old Male: A Lesion Beyond the Common Demographic and Anatomical Norms.

Osseous choristomas, characterized by ectopic bone, are rare and typically found in the head and neck, particularly on the tongue. This report describes a unique case of an osseous choristoma in a 63-year-old male with an unusual posterior tongue location. An incidental base of tongue (BOT) mass was discovered during a bronchoscopy for lung biopsy.
