Sensorimotor gating impairments induced by MK-801 treatment may be reduced by tolerance effect and by familiarization in monkeys

Dizocilpine (MK-801) is a non-competitive NMDA antagonist that induces schizophreniclike effects. It is therefore widely used in experimental models of schizophrenia including prepulse inhibition (PPI) impairments in rodents. Nevertheless, MK-801 has never been tested in monkeys on a PPI paradigm. In order to evaluate MK-801 effects on monkeys’ PPI, we tested eight capuchin monkeys (Sapajus spp.) using three different doses of MK-801 (0.01; 0.02; 0.03 mg/kg). Results show PPI impairment in acute administration of the highest dose (0.03 mg/kg). PPI impairment induced by MK-801 was reversed by re-exposure to the PPI test throughout treatment trials, in contrast with rodent studies. These results indicate that tolerance effect and familiarization with PPI test may reduce the sensorimotor gating deficits induced by MK-801 in monkeys, suggesting a drug-training interaction

Mercury pollution and congenital malformations detected at birth in Porto Velho, Brazil, from 1997 to 2007

RESUMENLos posibles impactos negativos de la contaminación por mercurio en el río Madeira, Estado de Rondonia,Brasil, en la salud de los bebés recién nacidos fueron evaluados.

El tipo de malformaciones entre la población local y los casos transferidos deotras zonas de Rondonia fueron comparados. Malformaciones neurológicas relacionadas se encontraron enel 45% de los casos.

The incidence of congenital malformations was surveyed from the recordsof newborns in the main hospital of Porto Velho, Rondonia, from 1997 to 2007. The type of malformationsbetween local population and cases transferred from other areas in Rondonia were compared. Neurological relatedmalformations were found in 45% of the cases. The proportion of neurological defects in the local population wasslightly higher than in transferred cases. Non-neurological malformations represented 43% of the sample and, 11.4%were unspecified.

Comparative Anatomical Analyses of the Forearm Muscles of Cebus libidinosus (Rylands et al. 2000): Manipulatory Behavior and Tool Use

The present study describes the flexor and extensor muscles in Cebus libidinosus' forearm and compares them with those from humans, chimpanzees and baboons. The data is presented in quantitative anatomical indices for similarity. The capuchin forearm muscles showed important similarities with chimpanzees and humans, particularly those that act on thumb motion and allow certain degree of independence from other hand structures, even though their configuration does not enable a true opposable thumb. The characteristics of Cebus' forearm muscles corroborate the evolutionary convergence towards an adaptive behavior (tool use) between Cebus genus and apes

Cadastramento de doadores voluntários de Medula Óssea no REDOME

Anais do 35º Seminário de Extensão Universitária da Região Sul - Área temática: SaúdeO transplante de medula óssea consiste na substituição de uma medula óssea doente ou deficitária por células normais, com o objetivo de reconstituição de uma nova medula. Um fator que dificulta a realização do procedimento é a falta de doador compatível. Assim, quanto maior o número de novos doadores voluntários cadastrados no REDOME (Registro Brasileiro de Doadores Voluntários de Medula Óssea), maiores são as possibilidades de o paciente encontrar um doador compatível. Nosso projeto de extensão tem como objetivo a conscientização da população sobre o cadastramento de doadores voluntários de medula óssea nas regiões de Maringá, Cianorte e Paranavaí, por meio de campanhas de captação de doadores, palestras de conscientização e divulgação sobre a doação e o transplante de medula óssea. O projeto vem colaborando no crescimento do REDOME com doadores mais conscientes sobre a responsabilidade do cadastro no banco. Assim, nossa equipe deve continuar realizando o trabalho de conscientização da população, pois quanto maior o número de doadores, maior é a possibilidade de se encontrar um doador compatíve

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation.

The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.
