Evaluation of Residual Infectivity after Sars-CoV-2 Aerosol Transmission in a Controlled Laboratory Setting
Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is mainly transmitted through respiratory droplets, aerosols, or direct contact with fomites from an infected subject. It has been reported that SARS-CoV-2 is stable and viable in aerosol up to 16 h in controlled laboratory conditions. However, the aerosolization conditions varied a lot between the studies. In this work, an experimental laboratory model of SARS-CoV-2 aerosolization…
Sars-CoV-2 Short-Time Infection Produces Relevant Cytopathic Effects in Vero E6 Cell Line
Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is mainly transmitted through respiratory droplets from positive subjects to susceptible hosts or by direct contact with an infected individual. Our study focuses on the in vitro minimal time of viral absorption as well as the minimal quantity of virus able to establish a persistent infection in Vero E6 cells. We observed that 1 min of in vitro virus exposure is sufficient to gener…
Meta‐analysis of Brazilian genetic admixture and comparison with other Latin America countries
OBJECTIVES: This study aims at performing a systematic review and meta-analysis with the studies of genetic admixture inference of Brazilian population and to compare these results with the genetic admixture levels in other Latin American countries. METHODS: We searched for articles regarding the estimation of Brazilian genetic admixture published between 1980 and 2014 that used autosomal markers. Then, conducted meta-analyses at the whole-countr…
Phylogenetic relationships among the Lorisoidea as indicated by craniodental morphology and mitochondrial sequence data
The phylogeny of the Afro‐Asian Lorisoidea is controversial. While postcranial data attest strongly to the monophyly of the Lorisidae, most molecular analyses portray them as paraphyletic and group the Galagidae alternately with the Asian or African lorisids. One of the problems that has bedevilled phylogenetic analysis of the group in the past is the limited number of taxa sampled for both ingroup families. We present the results of a series of …

Primate immunoglobulin heavy chain constant gamma genes
Phylogenetic relationships among Malagasy lemurs as revealed by mitochondrial DNA sequence analysis
Field blood conservation for DNA extraction
During field studies in tropical areas researchers are faced up to the problem of conserving blood at ambient temperatures sometimes for several months. The use of liquid nitrogen is uneasy, expensive and time consuming. Here we present two methods of blood conservation used during two expeditions in Madagascar which gave us very positive results: the blood was conserved in the field at ambient temperature for up to three months for further succe…
No correlation between chimerism and fertility inCallithrix jacchus (Callithricidae, Primates)
In this study, 40 individuals ofCallithrix jacchus were analyzed in order to investigate the frequency of chimerism and to determine whether the fertility of the colony was in any way affected by chimerism. In the individuals considered the degree of chimerism ranged from 2% to 97% and no correlation was established between the degree of chimerism and fertility of the individuals. Many “good breeders” were chimeric and the best female breeders di…
Highly repeated DNA sequences and systematics of malagasy primates
Newly evolved highly repeated DNA sequences ofTupaia glis (Tupaiidae, Scandentia)
Molecular biology and systematics of an extinct Lemur
Frequencies of oral pathologies in a sample of 767 non-human primates
Highly repeated DNA sequences as phylogenetic markers among the galaginae
Highly repeated DNA sequences were investigated as potential phylogenetic indicators among five species of galagines. One lorisine, one cheirogaleid, and two lemurid species were also investigated as progressively more distant outgroups. The lorisids displayed strong conservatism with regard to these sequences, to the point where the galegine species proved difficult to differentiate. When restriction fragment differences were observed, the galag…
The high genetic homology of threeMacaca fascicularis and twoMacaca mulatta subspecies on the basis of their highly repeated DNA restriction patterns
Highly repeated DNA analysis and systematics of the Lemuridae, a family of Malagasy prosimians
Enamel hypoplasias in a 19th century population from Northern Italy
In a sample from northern Italy of the second half of the 19th century hypoplasias in maxillary and mandibular anterior teeth was examined. The maxillary canine is the most frequently affected tooth. Frequencies of hypoplasias show slightly lower figures than other 19th century skeletal populations. The age interval most affected was between 2 and 4 years and suggests an association with stress at weaning and immediately thereafter.
Comparative analysis of DNA restriction patterns ofHomo, Pan troglodytes eMacaca fascicularis after hybridization with human genomic probes
In the present work, Eco RI digested genomic DNA fromMacaca fascicularis, Pan troglodytes and Man were hybridized with three human probes (β1-Integrin, pAW101; anderb-B2) and the relative restriction patterns are presented. After hybridization with theβ1-Integrin probe it was possible to demonstrate a high intraspecific variability in the Macaca and Pan sample, while the other two probes utilized didn’t show any difference among the different spe…
