Biochemical changes in Curimbat á subjected to transport stress and exposed to an agricultural fair

AbstractFish known as Curimbat á (Prochilodus lineatus) suffered a reduction in natural stocks due to predatory fishing and environmental deterioration; these are among the reasons for increased interest in the inclusion of this species in agricultural fairs. The aim of this study was to evaluate whether transport and exposure to an agricultural fair alters plasma biochemical parameters in curimbat ás. Blood samples were collected at 0 h (before transport), 10 h (end of transport), and 72 h (end of exposure to agricultural fair). Plasma cortisol levels increased after 72-h exposure to agricultural fair compared with initial collection (0 h). Plasma reactive oxygen species levels were lowe r in fish at 72-h exposure to agricultural fairs compared with those at initial collection, while plasma thiobarbituric acid reactive substances levels were higher after 10 h of transport than at initial collection (0 h). Plasma superoxide dismutase and glutathione S-transferase activities were lo wer after 10 h of transport than at initial collection, while plasma glutathione peroxidase activity was higher in fish exposed for 72 h at the agricultural fair compared with initial collection (0 h). Plasma total protein, albumin, and glucose levels were higher after 10 h of transport than at initial collection, while triglycerides levels were higher after 10 h of transport and 72-h exposure to the agricultural fair than at init...

Authors: Nagy P, Molnar B, Nemes B, Schupbach P, Windisch P Abstract The aim of this case series was the histologic evaluation of guided tissue regeneration utilizing deproteinized bovine bone mineral (DBBM) when regenerative surgery was combined with (test) or without (control) early orthodontic tooth movement. Core biopsy samples were harvested from previously defected sites after 9 months. The histologic section showed integration of DBBM particles in newly formed bone in the apical and middle thirds of the defect, while in the coronal part, graft materials were mainly embedded in connective tissues in the contr...

Authors: Al Balbeesi HO, Al Kawari HM, Al Tamimi AS, Al Mubarak I, Al Ibrahim KI, Divakar DD Abstract In the present study, the authors evaluated the association of canine impaction with different skeletal discrepancies in two planes of space (sagittal and vertical). Cephalometric and orthopantomographic radiographic images of 45 patients with one or more impacted canines were used in this retrospective study. Five radiographic morphologic parameters-ANB angle, canine angulation, angle between the Frankfort horizontal plane and the mandibular plane (FH-MP), Wits appraisal analysis, and axial inclination of the maxi...
