Distribution of injectates in the thoracic paravertebral space of the dog and cat: A cadaveric study.

Background: Thoracic paravertebral block (TPVB) entails injecting a local anesthetic inside the thoracic paravertebral space (TPVS). Loss of resistance to air injection (air-LOR) was the first technique described in humans to locate the TPVS. To date, no study has investigated the spread of any substance after injection into the TPVS using the air-LOR technique nor has described the cranial and caudal limits of the space.

Pharmacokinetics of buprenorphine following constant rate infusion for postoperative analgesia in dogs undergoing ovariectomy.

Objective: To investigate the pharmacokinetics of buprenorphine and its main active metabolite, norbuprenorphine, after administration of an intravenous loading dose followed by constant rate infusion (CRI) in dogs.

Study Design: Prospective, clinical study.

Animals: A total of seven healthy dogs undergoing elective ovariectomy.

[The neuropsychology of prodromal schizophrenia. Brief review and proposal of a tests battery for clinical use].

The study of the neuropsychological profile of schizophrenic patients has provided systematic results in linking specific deficit (working memory, verbal learning, attentive and executive functioning, social cognition) to the functional outcome of subjects. More recently this approach has been applied to younger subjects, from the age of 14, that show prodromal signs of a possible psychotic conversion (ultra-risk subjects). The review is at first intended to describe the clinical and experimental studies that investigated the cognitive and neuropsychological profile of subjects at ultra-risk for psychosis.

Restored perfusion and reduced inflammation in the infarcted heart after grafting stem cells with a hyaluronan-based scaffold.

The aim of this study is to investigate the blood perfusion and the inflammatory response of the myocardial infarct area after transplanting a hyaluronan-based scaffold (HYAFF(®) 11) with bone marrow mesenchymal stem cells (MSCs). Nine-week-old female pigs were subjected to a permanent left anterior descending coronary artery ligation for 4 weeks. According to the kind of the graft, the swine subjected to myocardial infarction were divided into the HYAFF(®) 11, MSCs, HYAFF(®) 11/MSCs and untreated groups.

Comparison between Culture Conditions Improving Growth and Differentiation of Blood and Bone Marrow Cells Committed to the Endothelial Cell Lineage.

The aim of this study was to compare different cell sources and culture conditions to obtain endothelial progenitor cells (EPCs) with predictable antigen pattern, proliferation potential and in vitro vasculogenesis. Pig mononuclear cells were isolated from blood (PBMCs) and bone marrow (BMMCs). Mesenchymal stem cells (MSCs) were also derived from pig bone marrow.
