Abstract Background Parotid gland agenesis is a rare, congenital, usually asymptomatic disorder.Until now, only 24 cases with unilateral, incidentally found, parotid gland agenesis have been described.Here, we present the first reported case of an ipsilateral preauricular neoplasm in a patient with unilateral parotid gland agenesis.During surgery,
Nowadays, security guard patrol services are becoming roboticized.However, high construction prices and complex systems make patrol robots difficult to be popularized.In this research, a simplified autonomous crossbow patrolling robot is proposed, which is fabricated by upgrading a wheeling household robot with stereo vision system (SVS), radio fre
Aldose reductase (AR) plays an important role in the development of several long-term diabetic complications.Inhibition of AR activities is a strategy for controlling complications arising from chronic diabetes.Several AR inhibitors have been reported in the literature.Flavonoid type compounds are shown to Energy Support have significant AR inhibit
Graphite anode slurry of lithium-ion flow battery was prepared by the method of ball milling.The morphology, conductivity, specific capacity and cycle performance of graphite anode slurry were studied.Results show that the addition of conductive carbon material can improve the suspension stability of the electrode slurry; the ball milling process c
