The mouthparts of the spiny lobster Panulirus argus hold primarily two types of setae-simple setae and cuspidate setae. Mechanosensory neurons from these setae were examined by electrophysiological recordings. The population of simple setae contained two types of mechanosensory neurons: displacement-sensitive neurons, which responded to deflection at the setal base; and bend-sensitive neurons, whi

Urinary cotinine (U-cotinine) as a biomarker of environmental tobacco smoke exposure was evaluated in 14 children (age 4-11 y) and in 7 adults who were exposed to environmental tobacco smoke at an air nicotine level of 110 mg/m3 for 2 h in a bus. Nicotine in air and U-cotinine were measured by gas chromatography/mass spectrometry before, during, and after the experiment. U-cotinine rose rapidly to

The content of low molecular weight carbohydrates (LMWC, glucose, fructose, sucrose, raffinose, stachyose and verbascose) was investigated in 29 cultivars of vining peas after blanching and freezing. The peas were harvested at about the same degree of ripeness. There was a positive correlation between the amount of raffinose, stachyose and sorbitol, while a high content of verbascose only could be

This paper presents a digital hardware implementation of a novel wavelet-based event detector suitable for the next generation of cardiac pacemakers. Significant power savings are achieved by introducing a second operation mode that shuts down 2/3 of the hardware for long time periods when the pacemaker patient is not exposed to noise, while not degrading performance. Due to a 0.13-mu m CMOS techn

AMP-activated protein kinase (AMPK) is a key molecular regulator of cellular metabolism, and its activity is induced by both metformin and thiazolidinedione antidiabetic medications. It has therefore been proposed both as a putative agent in the pathophysiology of type 2 diabetes and as a valid target for therapeutic intervention. Thus, the genes that encode the various AMPK subunits are intriguin

Popular Abstract in Swedish Denna avhandling redogör för cellulär lokalisation, reglering och funktion av två nya peptider, ghrelin och CART, i pankreas (bukspottskörteln). Pankreas och de Langerhanska öarna: Pankreas består av en exokrin del, som producerar matspjälkningsenzymer till mag-tarm kanalen, och en endokrin del som producerar hormoner som insöndras i blodomloppet. Endokrina pankreas bUntil recently, the islets of Langerhans were thought to harbour four main cell types characterised with respect to principal hormone product. Here we show that the novel hormone ghrelin is expressed in a fifth islet cell type, the islet ghrelin cell, in humans and rodents. The cells are developmentally regulated in that they are numerous around birth and fewer in the adult. The islet ghrelin cell

Historik över olika inspelningar av jazzmelodin "Wang Wang Blues" med anledning av 80-årsminnet av dess första inspelning (med Paul Whitemans orkester 1920).

We compared the use of Norian SRS, an injectable calcium phosphate bone cement, with functional treatment of redisplaced distal radial fractures in a prospective randomized study of 20 patients. The redisplaced fractures were either rereduced and stabilized by Norian SRS, or the displaced position was accepted and was not rereduced. All wrists were immobilized in a short-arm dorsal splint for 1 we

Idiopathic facial paralysis, or Bell's palsy, shows a nonepidemic pattern that might indicate reactivation of a latent microorganism such as herpes simplex type I as a causative agent. Thirty percent of patients with Bell's palsy given no treatment will not recover completely, and 5% will have severe sequelae. The aim of this study was to find out whether treatment with an antiviral drug in combin

This study with the Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrument Container (CARIBIC) platform investigates the aerosol elemental concentrations at 9-11 km altitude in the northern hemisphere. Measurements from 31 intercontinental flights over a 2-year period between Germany and Sri Lanka/Maldives in the Indian Ocean are presented. Aerosol samples were collected

Abstract in French 244 hanches chez 230 malades consécutifs ont été opérées avec une prothèse cimentée à tête de 32 mm. L'âge moyen à la chirurgie était 77 (46–96) années. Au délai de 10 ans 89 malades (95 hanches) étaient morts et 33 malades (35 hanches) non revus à cause de l'âge ou de problèmes médicaux. 13 hanches avaient été révisées pour descellement aseptique, deux pour infection, une pour In 230 consecutive patients 244 hips were operated with a 32-mm cemented prosthesis. The mean age at surgery was 77 (46-96) years. At the 10-year follow-up 89 patients (95 hips) were dead and 33 patients (35 hips) did not attend because of old age or medical problems. Thirteen hips had been revised for aseptic loosening, two for infection, one for recurrent dislocations, and one for fracture. Four

Background--The clinical benefits of lipid lowering with statins are attributed to changes in plaque composition leading to lesion stability, but supporting clinical data from human studies are lacking. Therefore, we investigated the effect of 3 months of pravastatin treatment on composition of human carotid plaques removed during carotid endarterectomy. Methods and Results--Consecutive patients w
