The aim of this study was to investigate the effects of transplanted Wharton's jelly mesenchymal stem cells (WJMSCs) of caprine umbilical cord on cutaneous wound healing process in goat. After collection of caprine pregnant uterus of mixed breed goats from abattoir, the Wharton's jelly (WJ) of umbilical cord was harvested. The tissues were minced in ventilated flasks and explant culture method was used for separating mesenchymal stem cells (MSCs). ⋯ The histopathological study revealed that re-epithelialization was complete at days 7 in treated wounds with WJMSCs, whereas in control wound the wounds still showed incomplete epithelialization 12 days after wounding. Also, microscopic evaluation showed less inflammation, thinner granulation tissue formation with minimum scar in the treated wounds in comparison with control wounds. In conclusion, this study demonstrates the beneficial effect of caprine WJMSCs in cutaneous wound healing in goat.

The aim of this study was to evaluate the effects of a recruiting maneuver (RM) on lung aeration, gas exchange, and respiratory mechanics during general anesthesia in mechanically ventilated dogs. A thoracic computed tomography (CT) scan, an arterial blood sample, and measurement of respiratory mechanics were performed 10 min before (baseline) and both 5 and 30 min after a vital capacity RM in 10 dogs under general anesthesia. The RM was performed by inflating the lung at 40 cm H(2)O for 20 s. ⋯ Lung aeration and gas exchange improved significantly 5 min after the RM compared to baseline and returned to values similar to baseline by 30 min. Static lung compliance was not significantly affected by the RM. An RM induces a temporary improvement in lung function in healthy dogs under general anesthesia.

Comparative Study
Comparison of invasive and non-invasive blood pressure monitoring during clinical anaesthesia in dogs.
Monitoring blood pressure during anaesthesia is widely recommended in man and animals. The accuracy of any device used to measure blood pressure is an important consideration when selecting monitoring equipment, the ANSI/AAMI SP10 standard is widely cited in this respect in recent veterinary publications. ⋯ The bias (and limits of agreement) between invasive and non-invasive measurement was 7.1 mmHg (+/-34.7) for systolic blood pressure, -1.8 mmHg (+/-27.4) for mean blood pressure and 6.9 mmHg (+/-27.5) for diastolic blood pressure. In a clinical setting the bias between invasive and non-invasive measurement techniques was similar or smaller than laboratory reports, however the limits of agreement were considerably wider suggesting that care should be exercised when interpreting NIBP values.

The increasing demand for fishery products and the technical and commercial opportunities now available make the development of aquaculture an important subject for the policy of the fishery sector, in particular concerning aspects of its environmental and ecological sustainability. The latest studies show that it is possible to apply an ecological approach to the aquaculture sector and hence increase the interactions between fisheries and other activities such as fish/molluscs, fish/seaweed, rice-growing/fish. ⋯ In order to support and facilitate trade, but at the same time ensure the safety and quality of products, a harmonization of the policies for food safety protecting the products throughout the whole food chain is required (from the sea to the table). The above mentioned policy, based on scientific knowledge, relies on the analysis of risks from the competent Authorities and on the proper application of HACCP from the industries of the sector.
