thermal variation during osteotomy with different dental implant drills: a standardized study in bovine ribs.	this study evaluated thermal variation (heat generation) by dental drills of similar geometries, made from different materials, during performance of 450 standardized osteotomies in bovine ribs to simulate implant site preparations.	2017	28114241
image-guided intrathecal baclofen pump catheter implantation: a technical note and case series.	objective medically refractory spasticity and dystonia are often alleviated with intrathecal baclofen (itb) administration through an indwelling catheter inserted in the lumbar spine. in patients with cerebral palsy, however, there is a high incidence of concomitant neuromuscular scoliosis. itb placement may be technically challenging in those who have severe spinal deformity or who have undergone prior instrumented thoracolumbar fusion. although prior reports have described drilling through the ...	2017	28156208
detection of hev-specific antibodies in four non-human primate species, including great apes, from different zoos in germany.	the hepatitis e virus (hev) has been described in humans and various animal species in different regions of the world. however, the knowledge on natural hev infection in non-human primates and the corresponding risk of zoonotic transmission is scarce. to determine whether primates in captivity are affected by hev infection, we investigated 259 individual sera of clinically healthy non-human primates of 14 species from nine german zoos. using a commercial double-antigen-sandwich elisa and a comme ...	2018	29168441
detection of hepatitis e virus antibodies among cercopithecidae and hominidae monkeys in cameroon.	we screened hepatitis e from 15 species of non-human primates. anti-hev igg was detected in 11.1% (1/9) mandrillus sphinx, 14.3% (2/14) gorilla gorilla, 5.9% (4/67) pan troglodytes and 8.7% (2/23) mandrillus leucophaeus, whereas anti-hev igm was detected in 1.5% (1/18) papio anubis, 28.6% (2/7) cercocebus agilis and 1.5% (1/67) pan troglodyte.	2019	31179536
competition, seed dispersal and hunting: what drives germination and seedling survival in an afrotropical forest?	disentangling the contributions of different processes that influence plant recruitment, such as competition and seed dispersal, is important given the increased human-mediated changes in tropical forest ecosystems. previous studies have shown that seedling communities in an afrotropical rainforest in southeastern nigeria are strongly affected by the loss of important seed-dispersing primates, including cross river gorillas (gorilla gorilla diehli), chimpanzee (pan troglodytes elioti) and drill ...	2019	31024680
comparative performance of orangutans (pongo spp.), gorillas (gorilla gorilla gorilla), and drills (mandrillus leucophaeus), in an ephemeral foraging task.	a goal of the comparative approach is to test a variety of species on the same task. here, we examined whether the factors that helped capuchin monkeys improve their performance in a dichotomous choice task would generalize to three other primate species: orangutans, gorillas, and drill monkeys. in this task, subjects have access to two options, each resulting in an identical food, but one (the ephemeral option) is only available if it is chosen first, whereas the other one (the permanent option ...	2020	33135209
genome sequences of novel members of previously described dna and rna virus families, isolated from feces of a drill monkey in nigeria.	the genomes of seven novel members of previously described dna and rna virus families are described here. these viruses were recovered using a viral metagenomic approach from the stool of a drill monkey (mandrillus leucophaeus) housed in a sanctuary in cross river state, nigeria.	2020	32327518
