Particulate bone plays a crucial role in various oral and maxillofacial surgical procedures, including reconstruction, implantation, and craniofacial surgery. Autologous bone and deproteinized bovine bone xenografts are the two primary resources used for such procedures, with the former demonstrating superior cost-effectiveness and reduced comorbidity rates, particularly in cases involving donor zones. However, a significant challenge lies in acquiring uniformly sized autologous particulate bone specimens, with existing tools often yielding coarse particles at a high cost. Consequently, commercial bone xenograft solutions are frequently favored despite lower standards. This technical note introduces a novel technique for swiftly, safely, and efficiently obtaining autologous particulate bone specimens. The procedure involves the use of a motor handpiece fitted with a micro drill and surgical spoon to collect the bone particles. The continuous irrigation with saline maintains a clear surgical field during the milling process. The collected bone particles are then transferred to a metal capsule for further use. This technique offers a promising solution to the challenge of inconsistent particle size associated with harvesting using traditional methods, providing surgeons with a reliable and efficient method of obtaining autologous particulate bone samples.

Progressive osseous heteroplasia(POH)is an ultra-rare autosomal dominant disabling disorder characterized by heterotopic ossification(HO).It is caused by heterozygous inactivating mutations in the GNAS(guanine nucleotide-binding protein alpha-stimulating activity polypeptide)***,the molecular mechanisms underlying HO remain poorly *** a treatment for POH is not yet available,the identification of the mechanisms driving POH in affected tissues using gene expression may be of great help to underestand the molecular basis of POH and develop new therapeutic approaches.

Nature tourism and particularly tourism in national parks have acquired significant importance in contemporary societies. Post-Fordist consumers have reevaluated the meanings of ‘nature' and ‘natural spaces' and now avoid standardization to seek singularity. Tourism in national parks is a consequence of this tendency and has both positive and negative aspects. The purpose of this sociological research is to describe the most relevant conflicts in the Picos de Europa National Park(Spain) involving the park's conservation, local economic development,and tourism. Seven in-depth interviews and three focus groups were addressed to key local *** this research were identified three chief areas of existing or potential inter-related conflicts and the main actors interacting with them. The first is on population, particularly, the negative consequences of depopulations on the local socio-economic development and the environment. A second source of conflicts identified is caused by the difficult conciliation between commercial exploitation and conservation of the protected natural area. More precisely, this specific form of tourism positively contributes to the economy of local communities whilst problems can arise for the conservation goals of National Parks. Thirdly, in this research is also analyzed the institutional governance and the inter and intra-governmental conflicts as well as with the Park's management body. These findings provide important information for the improved management of tourism and conflicting interests in natural parks.
