OBJECTIVE to evaluate early osseointegration of dental implants installed with two different drilling protocols. MATERIAL AND METHODS thirty-six cylindrical shape Mozo Grau implants, with a diameter of 3.75 and 11 mm long, were placed into the distal condyle (submerged) of each femur of 18 New Zealand rabbits. In the control group, a 3.3 mm diameter drill(More)
To evaluate the effects of induced hypercapnia on the electroretinogram (ERG) in beagle dogs anaesthetized with isoflurane and sevoflurane. Binocular, full-field flash photopic and scotopic ERGs were obtained from six healthy neutered female beagle dogs. In order to determine Vmax and the photopic negative response (PhNR), photopic ERG luminance–response(More)
Azaspiracids (AZAs) are marine biotoxins produced by the dinoflagellate Azadinium spinosum that accumulate in several shellfish species. Azaspiracid poisoning episodes have been described in humans due to ingestion of AZA-contaminated seafood. Therefore, the contents of AZA-1, AZA-2 and AZA-3, the best-known analogs of the group, in shellfish destined to(More)
Azaspiracids (AZAs) are marine toxins produced by Azadinium spinosum that get accumulated in filter feeding shellfish through the food-web. The first intoxication was described in The Netherlands in 1990, and since then several episodes have been reported worldwide. Azaspiracid-1, AZA-2, and AZA-3 presence in shellfish is regulated by food safety(More)
Yessotoxin (YTX) is a marine phycotoxin produced by dinoflagellates and accumulated in filter feeding shellfish. Although no human intoxication episodes have been reported, YTX content in shellfish is regulated by many food safety authorities due to their worldwide distribution. YTXs have been related to ultrastructural heart damage in vivo, but the(More)
Alloplastic calcium phosphate bone substitutes such as hydroxyapatite (HA) and tricalcium phosphate (TCP) have been studied extensively due to their composition closely resembling the inorganic phase of bone tissue. On the same way, by manipulating the HA/TCP ratio it may be possible to change the substitution rate and the bioactivity of these materials, an(More)
OBJECTIVE The effect on the marginal peri-implant tissues following repeated platform switching abutment removal and subsequent reconnection was studied. MATERIAL AND METHODS Six adult female Beagle dogs were selected, and Pm3 and Pm4 teeth, both left and right sides, were extracted and the sites healed for 3 months. At this time, 24 bone level (BL)(More)
OBJECTIVE To determine the minimum alveolar concentration (MAC) of isoflurane in cattle. STUDY DESIGN Prospective study. ANIMALS Sixteen healthy adult female Holstein-Friesian cattle weighing 612 ± 17 kg (× ± SEM) and aged 5.7 ± 0.9 years old. METHODS The unsedated cattle were restrained in right lateral recumbency using a rope harness technique.(More)
Phycotoxins are marine toxins produced by phytoplankton that can get accumulated in filter feeding shellfish. Human intoxication episodes occur due to contaminated seafood consumption. Okadaic acid (OA) and dynophysistoxins (DTXs) are phycotoxins responsible for a severe gastrointestinal syndrome called diarrheic shellfish poisoning (DSP). Yessotoxins(More)
