CORRELATION BETWEEN INDIVIDUAL PRODUCTION AND SLAUGHTER TRAITS OF COBB 500 AND HUBBARD

The aim of this work is to define the correlation between the proportion of breast, thigh and drumstick relative to the weight before slaughter in relation to the weight of dressed grill ready carcass in two broiler hybrids (Hubbard and Cobb 500) at different ages (40 or 42 days). Positive correlation between the carcass prior to slaughtering and share of breasts, thighs and drumsticks, at the age of 40 (Hubbard) and 42 (Cobb 500) days, was monitored in Cobb 500 (except between the carcass before slaughter males and stakes thighs and drumsticks), and in line Hubbard (except between the carcass prior to slaughtering and share of breast in both sexes collectively). Positive correlation between the carcass processed for barbecue and shares breasts, thighs and drumsticks of the genotypes, in Cobb 500 (except between the carcass prior to slaughter men throat and share thighs and drumsticks), and Hubbard (except between the carcass prior to slaughtering and share of breast in both sexes collectively) at the age of 40 (Hubbard) and 42 (Cobb 500) days, was monitored

ANALYSIS OF INDIVIDUAL CHARACTERISTICS IN PRODUCTION ON A SHEEP FARM IN THE MUNICIPALITY OF ROGATICA AND FOCA

Analysis was conducted on the territory of Rogatica and Foca. The analysis included 30 randomly selected farms. Twenty sheep farms raising Pramenka different strains (Vlasic and Herzegovinian strain), while the other ten sheep farms raising sheep Württemberg race and crossed Tsigai, Romanovska and Texel sheep breeds. were analyzed by the following characteristics: number of household members, the total number of sheep, the total area of agricultural land, the selling price of 1 kg of lamb and the average weight of lambs during the sale and conducted a descriptive analysis of the results. Depending on the features found numerous smaller or larger variations. The greatest differences were recorded with the characteristics of the soil, bares the herd and the number of household members. The selling price and weight of lambs in the sale of unique values and indicate the possibility of a unique production technology and the natural and market conditions

Photonic conversion of hydroxyapapite to fluorapatite: A possible mechanism for laser-activated fluoride therapy

Purpose: This laboratory study aimed to determine whether laser activated fluoride (LAF) therapy of sensitive dentine causes conversion of apatite mineral to fluorapatite ("photonic conversion") and thereby reduces the risk of dental erosion. Materials and Methods: X-ray photoelectron spectroscopy was used to quantify changes in the atomic concentration of the elements fluorine, calcium, oxygen, phosphorus, carbon, nitrogen, and silicon, at five depths up to 52 nm in human dentine slabs with patent dentine tubules, which were either treated with neutral sodium fluoride gel (12,300 ppm) only, untreated, or subjected to laser-activated fluorid therapy (LAF) over a 12-week period. Results: Fluorine to calcium ratios were increased from zero (control) to 0.27 and 0.28 after fluoride gel and LAF, respectively. However, the chemical composition of dentine was affected by LAF, with the altered fluorine binding energy of 684.6 eV corresponding to formation of fluorapatite. No conversion to fluorapatite occurred when fluoride gel was applied under identical conditions but without lasing. Conclusion: Partial conversion of apatite minerals with LAF would contribute to the documented protective effects of LAF against dental erosion, and explains the benefits gained clinically when this treatment is applied to sensitive cervical root surfaces

The influence of surface microroughness and hydrophilicity of titanium on the up-regulation of TGFβ/BMP signalling in osteoblasts

The topography of titanium implants has been identified as an important factor affecting the osseointegration of surgically placed dental implants. Further modification to produce a hydrophilic microrough titanium implant surface has been shown to increase osseointegration compared with microrough topology alone. This study aimed to determine possible molecular mechanisms to explain this clinical observation by examining differences in the whole genome mRNA expression profile of primary human osteoblasts in response to sand-blasted acid-etched (SLA) and hydrophilic SLA (modSLA) titanium surfaces. A decrease in osteoblast proliferation associated with the titanium surfaces (modSLA > SLA > control) correlated with an increase in expression of the osteogenic differentiation markers BSPII and osteocalcin. Pathway analysis demonstrated that a number of genes associated with the TGFβBMP signalling cascade (BMP2, BMP6, SP1, CREBBP, RBL2, TBS3, ACVR1 and ZFYVE16) were significantly differentially up-regulated with culture on the modSLA surface. BMP2 was shown to have the largest fold change increase in expression which was subsequently confirmed at the protein level by ELISA. Several other genes associated with the functionally important mechanisms relevant to bone healing, such as Wnt signalling (CTNNA1, FBX4, FZD6), angiogenesis (KDR), osteoclastogenesis (HSF2, MCL1) and proteolysis (HEXB, TPP1), were also differentially regulated. These results suggest that chemical (hydrophilic) modification of the SLA surface may result in more successful osseointegration through BMP signalling. © 2010 Elsevier Ltd.Link_to_subscribed_fulltex

Combined CPP-ACP and photoactivated disinfection (PAD) therapy in arresting root surface caries: a case report

A 19-year-old male was referred to the School of Dentistry, University of Queensland for management and treatment of uncontrolled root caries. A total of 12 teeth had non-cavitated root carious lesions requiring treatment. The lesions were treated with a daily application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP; GC Tooth Mousse) and in-surgery photo-activated disinfection ( PAD). Laser fluorescence (KaVo Diagnodent) was used to monitor the changes in the carious lesions. The combination of CPP-ACP and PAD proved to be very effective and holds great potential as a recommended treatment for stabilising root surface caries in the clinical practice
