A split-sample replication criterion originally proposed by J. E. Overall and K. N. Magee (1992) as a stopping rule for hierarchical cluster analysis is applied to multiple data sets generated by sampling with replacement from an original simulated primary data set. An investigation of the validity of this bootstrap procedure was undertaken using different combinations of the true number of latent populations, degrees of overlap, and sample sizes. The bootstrap procedure enhanced the accuracy of identifying the true number of latent populations under virtually all conditions. Increasing the size of the resampled data sets relative to the size of the primary data set further increased accuracy. A computer program to implement the bootstrap stopping rule is made available via a referenced Web site.

Parasites have their strongest impact on fitness when host defences deplete resources needed for other critical life-history stages, such as development, breeding or migration. Among birds, one greatly neglected stage that could be altered by parasites is post-juvenile moult (PJM), through which yearling juvenile birds replace their fast-generated, low-quality juvenile feathers with adult-like feathers after leaving the nest. The earlier the birds complete PJM, the earlier they will be prepared to withstand forthcoming challenges, such as adverse winter conditions or migration.

Producing oral soft tissues using tissue engineering could compensate for the disadvantages of autologous grafts (limited availability and increased patient morbidity) and currently available substitutes (shrinkage). However, there is a lack of in vitro-engineered oral tissues due to the difficulty of obtaining stable pre-vessels that connect to the host and enable graft success. The main objective was to assess the connection of pre-vascularised 3D-bioprinted gingival substitutes to the host vasculature when subcutaneously implanted in immunodeficient mice.

Cocoa is a high value product and therefore a potential target for economic adulteration with less expensive ingredients. Carob flour is less expensive than cocoa powder and is frequently cited as a potential cocoa substitute. While carob has legitimate uses as a cocoa replacement, these characteristics also make it a potential adulterant of cocoa powder.

Introduction: Cerebral palsy (CP) is a group of permanent disorders of movement development that may cause activity limitations. In this context, robot-assisted therapy might play a key role in clinical management. This comprehensive systematic review aimed to investigate the efficacy of robotic systems in improving upper limb (UL) functions in children with CP.
