Ultrasonic mid-air haptic technologies, which provide feedback through airwaves produced using ultrasound, could be employed to investigate the sense of body ownership and immersion in virtual reality (VR) by inducing hand illusion (VHI). perception has solely been investigated for glabrous (hairless) skin, higher tactile sensitivity than hairy skin. In contrast, VHI paradigm typically targets ...

background and objectives: hyoscyamus reticulatus contains two distinguished tropane alkaloids, hyoscyamineand scopolamine and both of the compounds possesspotential acute or chronic toxicity. in the present study, a simple and efficient transformation system was established for in vitro hairy roots induction in hyoscyamus reticulatus. methods: effect of different factors including agrobacteriu...

BACKGROUND Wound closure is accomplished in most cases of myelomeningocele (MMC) by undermining of the skin edges surrounding the defect. However, large defects cannot be closed reliably by this simple technique. Due to the technical challenge associated with large MMC, surgeons have devised different methods for repairing large defects. In this paper, we report our experience of managing large...

BACKGROUND An incision of hairy skin of the rat's back provides a new model for postincisional pain to determine the importance of cutaneous anesthesia. METHODS Male Sprague-Dawley rats were anesthetized with sevoflurane and given a 0.6-ml subcutaneous injection of bupivacaine (0.25%) under the incision site or the medial lumbar dorsum or at the nuchal midline, 30 min before a 1.0-cm skin inc...

We follow up on our research demonstrating that aerotactile information can enhance or interfere with accurate auditory perception, even among uninformed and untrained perceivers [1]. Mimicking aspiration, we applied slight, inaudible air puffs on participants’ skin at the ankle, simultaneously with syllables beginning with aspirated (‘pa’, ‘ta’) and unaspirated (‘ba’, ‘da’) stops, dividing the...

Most of the studies aiming to investigate the human tactile sense are done on the glabrous skin. Still, there is a need for a quantitative method for evaluating nervous function of the hairy skin. Tactile direction discrimination, the ability to determine the direction of movement across the skin provides a clinical method to quantify tactile function of the hairy skin in humans. The method is ...

Receiving the Curt Stern Award makes me think of the year 1956, when Stern, an extraordinaryDrosophila geneticist with broad-ranging interests, becamepresident of the American Society of Human Genetics. It’s also the year I was born. During the first year of my life, Stern presided over the Society’s 10th annual meeting, in Ann Arbor. There, he delivered a presidential address entitled “On porc...

In awake human subjects, neural responses in cutaneous nerves to electrical stimulation were recorded with intrafascicular tungsten micro-electrodes. Changes in the activity of individual fibre groups during blocking procedures were recorded and correlated with simultaneous alterations in the perception of standardized stimuli. Light touch sensibility in hairy skin was mediated by A-beta-gamma ...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

Twenty-five rapidly adapting mechanoreceptor afferents were recorded in an in vitro preparation of rat skin and nerve. Single units were recorded while the skin was subjected to dynamic uniaxial stretch using a pseudo-Gaussian noise (PGN) input waveform. Force was the controlled variable in stretch stimuli. Measured loads and displacements were used to calculate tensile stresses, strains, and t...
