Avoidance of biological contaminants through sight, smell and touch in chimpanzees [PDF]

open access: yesRoyal Society Open Science, 2017
Avoiding biological contaminants is a well-known manifestation of the adaptive system of disgust. In theory, animals evolved with such a system to prevent pathogen and parasite infection. Bodily products are human-universal disgust elicitors, but whether

Mycosis Fungoides, Sézary Syndrome, and Cutaneous B‐Cell Lymphomas: 2025 Update on Diagnosis, Risk‐Stratification, and Management

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Disease Overview Primary cutaneous lymphomas are a rare and heterogeneous group of extranodal lymphomas that require the integration of clinical and histopathologic data for classification and treatment. Diagnosis Diagnosis and disease classification is based on histopathologic review and immunohistochemical staining of an appropriate skin ...

A meta-analysis of MHC diversity in Pan troglodytes verus

open access: yesRevue de Primatologie, 2014
We performed a meta-analysis of the Major Histocompatibility Complex (MHC) diversity for locus A, B, C, DQB1, DPB1 and DRB1 in Chimpanzees by selecting cohorts of animals for which MHC genotypes were available in publications and by extracting DNA ...

Why Are Nigeria-Cameroon Chimpanzees (Pan troglodytes ellioti) Free of SIVcpz Infection? [PDF]

open access: yesPLoS ONE, 2016
Simian immunodeficiency virus (SIV) naturally infects two subspecies of chimpanzee: Pan troglodytes troglodytes from Central Africa (SIVcpzPtt) and P. t. schweinfurtii from East Africa (SIVcpzPts), but is absent in P. t.

Efficient search for a face by chimpanzees (Pan troglodytes) [PDF]

open access: yesScientific Reports, 2015
AbstractThe face is quite an important stimulus category for human and nonhuman primates in their social lives. Recent advances in comparative-cognitive research clearly indicate that chimpanzees and humans process faces in a special manner; that is, using holistic or configural processing.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Incisor cross‐sectional area at the cementoenamel junction correlates with an increased reliance on frugivory in anthropoid primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

Chimpanzee subspecies and 'robust' australopithecine holotypes, in the context of comments by Darwin

open access: yesSouth African Journal of Science, 2009
On the basis of comparative anatomy (including chimpanzees, gorillas and other primates), Darwin1 suggested that Africa was the continent from which 'progenitors' of humankind evolved. Hominin fossils from this continent proved him correct.

Touch-screen-guided task reveals a prosocial choice tendency by chimpanzees (Pan troglodytes) [PDF]

open access: yesPeerJ, 2018
Humans help others even without direct benefit for themselves. However, the nature of altruistic (i.e., only the other benefits) and prosocial (i.e., self and other both benefit) behaviors in our closest living relative, the chimpanzee, remains ...
