Provedor de dados: 74
Autores: Baruffi,Marcelo Razera; Barbieri-Neto,J.; Pina-Neto,João Monteiro; Suerzut,C.E.; Casartelli,Cacilda.
Cytogenetic analyses were performed on a bone giant cell reparative granuloma (GCRG) and on three bone giant cell tumors (GCT). The present GCRG case is the second to be described cytogenetically. A modal chromosome number of 46 was observed in all samples. Clonal chromosome abnormalities were detected in all cases. The numerical alterations most frequently observed involved the loss of chromosomes 17 and 18. Among the structural anomalies observed, there was preferential involvement of chromosomes 6 and 10. Three GCT cases presented del(10)(p13) and two cases presented del(6)(q25) (1 GCRG and 1 GCT). These breakpoints mapped on 10p and 6q may harbour genes of importance in the development of bone giant cell tumors.

Provedor de dados: 74
Autores: Yan,Jian; Jiao,Yan; Li,Xinmin; Jiao,Feng; Beamer,Wesley G.; Rosen,Cliff J.; Gu,Weikuan.
Humans and guinea pigs are species which are unable to synthesize ascorbic acid (vitamin C) because, unlike rodents, they lack the enzyme L-gulonolactone oxidase (Gulo). Although the phenotype of lacking vitamin C in humans, named scurvy, has long been well known, information on the impact of lacking Gulo on the gene expression profiles of different tissues is still missing. This knowledge could improve our understanding of molecular pathways in which Gulo may be involved. Recently, we discovered a deletion that includes all 12 exons in the gene for Gulo in the sfx mouse, characterized by spontaneous bone fractures. We report here the initial analysis of the impact of the Gulo gene deletion on the murine gene expression profiles in the liver, femur and...

In this work we firstly tested the influence of low molecular weight fucoidan extracted from pheophicae cell wall on bidimensional cultured normal human osteoblasts behaviours. Secondly impregnation procedure with LMW fucoidan of bone biomaterial (Lubboc®) we explored in this bone extracellular matrix context its capabilities to support human osteoblastic behaviour in 3D culture. In bidimensionnal cultures we evidenced that: LMW fucoidan promotes human osteoblast proliferation, collagen type I expression and favours precocious alkaline phosphatase activity. Furthermore with LMW fucoidan von Kossa's staining was positive at 30 days and only positive at 45 days in absence of LMW fucoidan. In our three dimensional culture models with the biomaterial...

Autores: Zeppilli, Daniela; Vanreusel, Ann; Pradillon, Florence; Fuchs, Sandra; Mandon, Perrine; James, Tristan; Sarrazin, Jozee.
Despite the fragmented nature of hydrothermal vent (HV) fields, nascent vent sites are rapidly colonized by a pool of regional species. While succession of large animals at vents is relatively well established, we lack information on the associated meiofauna, in particular, on nematodes. The aim of the present study is to investigate the process of colonisation after 9 months of organic (wood and bone) and inorganic (slate) substrata by nematode assemblages deployed at the Eiffel Tower hydrothermal edifice on the Lucky Strike vent field on the Mid-Atlantic Ridge (MAR), at varying distances from visible hydrothermal activity. Abundance, biomass and diversity of colonising nematodes were compared with the results from an earlier similar two-year experiment....

Provedor de dados: 77
Autores: Cortés-Delgado,Natalia; Pérez-Torres,Jairo; Hoyos,Julio Mario.
Transparency technique to demonstrate cartilage and skeleton has been used from years 70. This consists basically of the muscle digestion through an enzyme (trypsine), and the staining of cartilage and skeleton using alcian blue and alizarin red on specimens previously fixed to formalin. This technique can be used to study the state of the cartilage and the bones in different stages of the development and to observe abnormalitys. Also it can be used to demonstrate museum specimen skeleton preserved in liquid. In this article is showed the application of this technique for the first time in rodents and adult bats, besides some annotations to optimize the procedure.

Live Performance, Carcass, and Bone Quality Responses of Grower and Finisher Broilers to Dietary Metabolizable Energy Levels
Provedor de dados: 89
Autores: Gopinger,E; Krabbe,EL; Surek,D; Lopes,LS; Avila,VS.
ABSTRACT Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days of age. There are many evidences that broilers changed their feed intake capacity due to genetic selection, especially when good quality pellets are fed, which suggests that modern broiler strains may achieve good performance when fed low metabolizable energy levels. The objective was to evaluate the energy efficiency, performance parameters, bone parameters, and carcass yield of 22- to 42-d-old broilers fed diets with energy levels below or above their requirements, while maintaining the density of all other nutrients. In total, 900 male broilers were distributed in a randomized block design, with five treatments...

Animals were assigned to one of the following treatments: 0 (free access to feed: ad libitum), 30 or 60% of feed restriction. Initial body weight (BW) averaged 5 kg and animals were slaughtered when they reached 20 kg BW. Data were submitted to regression analysis as function of feed restriction. Feed restriction reduced carcass weight, retail cuts weight, and chump proportion and increased neck proportion. Bone proportion also increased while muscle tissue and fat proportion (including...

The objective of this study was to estimate tissue composition of the carcass from physical composition of commercial cuts of F1 crossbred goats (Boer with females of non-defined racial standard) finished on native pasture with four levels of supplementation with concentrate (0.0; 0.5; 1.0 and 1.5% of BW in dry matter). It was used 24 non-castrated animals at initial body weight of 15.52 kg and at 120 days of age. The carcass was sectioned in the half, and from the lefthalf carcass, the following cuts were detached: leg, loin, ribs, shoulder and neck, which were dissected in muscle, bone and fat. Carcass weight and yield were predicted from the weight and yield of tissues in the commercial cuts by regression analysis. All the cuts can be used to predict...

Use of radiographic examinations in the diagnosis of Pulmonary Hypertrophic Osteopathy (OHP): report on three cases in dogs
Provedor de dados: 195
Autores: Candeias, Cíntia Zamponi Costa; da Silva, Débora Prado; Camargo, Ricardo Fuso; Alves, Jefferson Douglas Soares.
Pulmonary Hypertrophic Osteopathy (OHP) is a condition characterized by a bone neoformation resulting from periosteal response in long bones and extremities. It is secondary to intrathoracic diseases such as primary or metastatic tumors; pyelo-granulomatous diseases and primary malignancies in the pelvic organs. It may affect several species, and has no racial predisposition or biotype relation, although it’s commonly found in elder animals. The usual clinical signs are: increased temperature and edema in the affected limbs, reluctance to move and limping. However, some signs can be related to the primary disease. The pathophysiology is not yet fully understood, but there are different theories that explain the disease. This paper reports three cases seen...

Methods for evaluation of bone mineralization in foals
Provedor de dados: 195
Autores: Kerber, Claudia Ehlers.
Some of the main equine diseases are related to the musculoskeletal system, mainly during the bone developing in young animals. In São Paulo state, Brazil, the use of tropical grasses for grazing, the seasons and a general tendency to concentrate a large number of horses in small areas, frequently results on bone diseases, sometimes subtle, which depreciate the economic value of the horses and decrease the chance of a maximum performance. An early diagnosis of mineral imbalance play an important role once the bone diseases can be reversible when corrected on time. The author presents a review of physiology and pathophysiology of the bone. Also describe the methods available for diagnostic and suggest the phosphorus clearance as a sensitive, early, low cost...

The peculiarities of the masticator muscles in rodents
Provedor de dados: 45
Autores: Spataru,C.; Spataru,M.; Vulpe,V.; Lazar,M.
Comparative research concerning masticatory musculature in squirrel, muskrat and rabbit, take into account the emphasizing and morphofunctional interpretation of the osteomuscular particularities involved in the prehension and mastication processes. The development of the coronoid process on the muskrat and squirrel demonstrates the growing of the force when raising the mandible by increasing the action force attached to the temporal muscle, with insertion on the coronoid process. In comparison with that, in the case of rabbits, both the coronoid process and the temporal muscle are reduced. From a philogenetic point of view, it has been found that the species that have the articular condyle lowered at or under the level of the dental tables (carnivores)...

Cats with orthopedic conditions are a prominent part of the clinical work of veterinary. Conditions such as comminuted fractures, bone tumors and non-unions are often difficult to repair and may require the use of bone grafts for treatment. This study evaluated cortical bone allografts preserved in honey, frozen or lyophilized for correcting long bone defects created in the diaphysis of the right femur of domestic cats (n=24). In the control group (n=6), the defect was repaired using autogenous cortical bone graft. In the remaining animals (n=6/group), the defect was repaired with cortical bone allografts preserved in honey, frozen or lyophilized. Success of graft incorporation and length of time for consolidation were assessed through clinical,...

Comparison of subcutaneous inflammatory response to commercial and engineered zinc hydroxyapatite implants in rabbits
Provedor de dados: 45
Autores: Muñoz,L.C.; Cardona.-Ramirez,S.; Silva,R.F.
ABSTRACT Hydroxyapatite (HA) is widely used as a biomaterial for bone repair and metallic prostheses coating. The main limitations of the current commercial synthetic hydroxyapatite compounds include high cost and decreased availability, especially for veterinary medicine purposes. Additionally, it is thought that HA biocompatibility and bioactivity could be enhanced by the addition of metal compounds. The objective of this work was to compare the subcutaneous tissue response of commercial and engineered hydroxyapatite obtained from the bovine femur diaphysis mixed with different concentrations of hexa-hydrated Zinc Nitrate in rabbits. Twenty-Five New Zealand female rabbits were used. Five treatments were done according to HA composition (commercial HA, no...

Provedor de dados: 48
Autores: BERNAL,FABIÁN; HARTUNG,HANS-PETER; KIESEIER,BERND C.
Matrix metalloproteinases (MMPs) comprise a large group of endoproteinases that degrade all protein components of the extracellular matrix. Functionally, MMPs contribute to several different physiological as well as pathological conditions. The number of newly described MMPs has increased in recent years, although current knowledge about their expression pattern in various tissues remains incomplete. Here we analyzed the relative mRNA expression of the most recently described MMPs _ MT5-MMP (MMP-24), MT6-MMP (MMP-25), MMP-27 and epilysin (MMP-28) _ in a broad selection of rat tissues using real time-PCR. MMP-24 mRNA was found to be widely expressed with predominance in the central nervous system. MMP-25 mRNA, in contrast, exhibited peak expression levels...

In this work, biocompatibility, osteointegration, osteoconductivity, and biodegradation of a hydroxyapatite polyhydroxybutyrate new composite were evaluated. The composite was implanted in rabbits' bone defects and clinical, radiographic, histological, and histomorphometric data of these animals were compared with those of unfilled defects on the days 8th, 45th, and 90th after surgery. No significant differences existed between the groups for the evaluated clinical parameters. Radiographs showed bone-composite direct contact. Bone formed within the defect, interface and inside the composite. Significant differences were found between the bone and connective tissues percentage within the defect at all dates and at the interface on the 45th day, bone tissue...

Provedor de dados: 56
Autores: Fontes-Pereira,A.; Matusin,D.P.; Rosa,P.; Schanaider,A.; von Krüger,M.A.; Pereira,W.C.A.
A simple experimental protocol applying a quantitative ultrasound (QUS) pulse-echo technique was used to measure the acoustic parameters of healthy femoral diaphyses of Wistar rats in vivo. Five quantitative parameters [apparent integrated backscatter (AIB), frequency slope of apparent backscatter (FSAB), time slope of apparent backscatter (TSAB), integrated reflection coefficient (IRC), and frequency slope of integrated reflection (FSIR)] were calculated using the echoes from cortical and trabecular bone in the femurs of 14 Wistar rats. Signal acquisition was performed three times in each rat, with the ultrasound signal acquired along the femur's central region from three positions 1 mm apart from each other. The parameters estimated for the three...

Autores: Yanagihara,G.R.; Paiva,A.G.; Gasparini,G.A.; Macedo,A.P.; Frighetto,P.D.; Volpon,J.B.; Shimano,A.C.
High-impact exercise has been considered an important method for treating bone loss in osteopenic experimental models. In this study, we investigated the effects of osteopenia caused by inactivity in femora and tibiae of rats subjected to jump training using the rat tail suspension model. Eight-week-old female Wistar rats were divided into five groups (n=10 each group): jump training for 2 weeks before suspension and training during 3 weeks of suspension; jump training for 2 weeks before suspension; jump training only during suspension; suspension without any training; and a control group. The exercise protocol consisted of 20 jumps/day, 5 days/week, with a jump height of 40 cm. The bone mineral density of the femora and tibiae was measured by double...
