Improved method for making nondenaturing composite gradient gels for the electrophoretic separation of lipoproteins

Journal of Lipid Research, 2004
Nondenaturing gradient gel electrophoresis continues to be used widely for resolution and characterization of lipoprotein subclasses. Methods for making such gels in the laboratory have been published, but occasionally samples do not display uniform ...

(De)composing sociality: Disentangling individual‐specific from dyad‐specific propensities to interact

Methods in Ecology and Evolution, EarlyView.
Abstract In group‐living animals, relationships between group members are often highly differentiated. Some dyads can maintain strong and long‐lasting relationships, while others are only connected by weak or fleeting ties. More and more studies show that aspects of social relationships are related to reproductive success and survival.

Protective potential of antioxidant enzymes as vaccines for schistosomiasis in a non-human primate model

Frontiers in Immunology, 2015
Schistosomiasis remains a major cause of morbidity in the world. The challenge today is not so much in the clinical management of individual patients, but rather in population-based control of transmission in endemic areas.

Associative learning in baboons and humans: Species differences in learned attention to visual features [PDF]

, 1998
We examined attention shifting in baboons and humans during the learning of visual categories. Within a conditional matching-to-sample task, participants of the two species sequentially learned two two-feature categories which shared a common feature ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

An optimal factor analysis approach to improve the wavelet-based image resolution enhancement techniques [PDF]

, 2016
The existing wavelet-based image resolution enhancement techniques have many assumptions, such as limitation of the way to generate low-resolution images and the selection of wavelet functions, which limits their applications in different fields.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

Conservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Stopping Criterion for the Mean Shift Iterative Algorithm

, 2013
Image segmentation is a critical step in computer vision tasks constituting an essential issue for pattern recognition and visual interpretation. In this paper, we propose a new stopping criterion for the mean shift iterative algorithm by using images ...

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

Journal of Anatomy, EarlyView.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...
