Variation in grouping patterns, mating systems and social structure: what socio-ecological models attempt to explain [PDF]

, 2013
Socio-ecological models aim to predict the variation in social systems based on a limited number of ecological parameters. Since the 1960s, the original model has taken two paths: one relating to grouping patterns and mating systems and one relating to ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

A Characterization of Aerosolized Sudan Virus Infection in African Green Monkeys, Cynomolgus Macaques, and Rhesus Macaques

Viruses, 2012
Filoviruses are members of the genera Ebolavirus, Marburgvirus, and “Cuevavirus”. Because they cause human disease with high lethality and could potentially be used as a bioweapon, these viruses are classified as CDC Category A ...

Predictors of orbital convergence in primates: A test of the snake detection hypothesis of primate evolution [PDF]

, 2011
Traditional explanations for the evolution of high orbital convergence and stereoscopic vision in primates have focused on how stereopsis might have aided early primates in foraging or locomoting in an arboreal environment. It has recently been suggested

The DMHGABA Neurons Play a Crucial Role in The Regulation of Cold‐Induced White Adipose Browning through DMH to LPO Projection

Advanced Science, EarlyView.
GABAergic neurons in the dorsomedial hypothalamus (DMHGABA neurons) act as a key neuronal population controlling cold exposure‐induced white adipose tissue browning. DMHGABA neurons regulate the browning through DMH to the lateral preoptic area (LPO) projection.

CRH receptor genetic variation in a developmental primate model relevant to the risk to develop anxiety and depression

European Journal of Psychotraumatology, 2012
Background : Using a well-established non-human primate model of anxious temperament (AT) we characterized alterations in the neural circuit that underlie the dispositional risk to develop anxiety and depression.

Screening donors for xenotransplantation: The potential for xenozoonoses [PDF]

, 1994
Xenotransplantation is a potential solution to the current donor shortage for solid organ transplantation. The transmission of infectious agents from donor organs or bone marrow to the recipient is a well-recognized phenomenon following ...

Nurr1 Orchestrates Claustrum Development and Functionality

Advanced Science, EarlyView.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

Pathogenesis and Animal Models of Post-Primary (Bronchogenic) Tuberculosis, A Review

Pathogens, 2018
Primary and post-primary tuberculosis (TB) are different diseases caused by the same organism. Primary TB produces systemic immunity. Post-primary TB produces cavities to support massive proliferation of organisms for transmission of infection to new ...

DEL‐1 is an Endogenous Senolytic Protein that Inhibits Senescence‐Associated Bone Loss

Advanced Science, EarlyView.
Senescent bone marrow stromal cells accumulate in the aging bone microenvironment, promoting bone degeneration. DEL‐1, an endogenous secreted protein, acts as a natural senolytic that selectively eliminates these cells. By engaging a β3 integrin/CD73/adenosine/p38 MAPK/BCL‐2 pathway, DEL‐1 counters aging‐related bone loss, revealing promising ...
