BACKGROUND: According to Braak staging of Parkinson's disease (PD), detection of autonomic dysfunction would help with early diagnosis of PD. OBJECTIVE: To determine whether the autonomic nervous system is involved in the early stage of PD, we evaluated cardiovascular and sudomotor function in early untreated PD patients. METHODS: Orthostatic blood pressure regulation, heart rate variability, s...

PURPOSE To evaluate real-time parameters of palmar microcirculation before and after harvesting of the radial artery in coronary revascularization using a laser Doppler flowmetry and remission spectroscopy system (O2C). DESCRIPTION Fifteen patients (11 males, 54 +/- 4 years, mean New York Heart Association [NYHA] class of 2.3 +/- 0.3) were prospectively scheduled with control measurements of ...

The fibromatoses are a group of benign fibroblastic proliferations that vary from benign to intermediate in biological behavior. This article will discuss imaging characteristics and patient demographics of the adult type superficial (fascial) and deep (musculoaponeurotic) fibromatoses. The imaging appearance of these lesions can be characteristic (particularly when using magnetic resonance ima...

Variations in the course and distribution of common palmar digital nerves and arteries are rare. A classic common palmar digital nerves and arteries are defined as concomitant. During routine dissection classes to undergraduate medical students we observed formation of each common palmar digital nerve divided into 2 or 3 branches and formed a ring enclosing the corresponding common palmar digit...

As a member of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), Iran has a long-term space exploration program. Space radiation is one of the challenges facing humans when they go outside Earth's protective atmosphere and magnetic field. Space is an environment that the cardinal principles of radiation protection i.e. time, distance and shielding cannot be effectively ...

The carpal tunnel is a channel with fibroosseous walls leading from the deep flexor space of the forearm into the palm of the hand. Superficially it is bounded by the flexor retinaculum which stretches from the trapezium and scaphoid laterally to the pisiform and hamate medially. This tough sheet blends proximally with the deep fascia of the forearm and distally with the palmar aponeurosis. The...

The paper synthesizes the existing data on the pathology of dermatoglyphics in three severe brain affections (epilepsy, autism and sekelary IEP-ies), followed upon a total number of 439 subjects (of which 102 are affected by epilepsy, 137 – by infantile autism and 200 – by sekelary IEP-ies) with ages between 2 and 18 years, all coming from the region of Moldova. An important observation to be m...

Background: Few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. Case Presentation: A 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. At ulrasonographic examination, a simple cyst was detected. Sensory response of palmar cutaneous branch of median nerve was absent at the affec...

Introduction: Deep neck space infections (DNSI) are serious diseases that involve several spaces in the neck. The common primary sources of DNSI are dental infections, tonsillar and salivary gland infections, malignancies, and foreign bodies. With widespread use of antibiotics, the prevalence of DNSI has been reduced. Common complications of DNSI include airway obstruction, jugular vein thrombo...

Under development for launch in July 1998, Deep Space One (IX 1 ) is the first flight of NASA’s New Millennium Program, chartered to validate selected technologies required for future low-cost space science programs. Advanced technologies chosen for validation on DS 1 include solar electric propulsion, high-power solar concentrator arrays, autonomous on-board optical navigation, two low-mass sc...
