Rabies in tamarins (Callithrix jacchus) in the State of Ceará, Brazil, a distinct viral variant?
Memorias do Instituto Oswaldo Cruz, 2000 Presently, the State of Ceará reports the largest percentage of human rabies cases originated from wild animals in Brazil, transmitted by the principal simian species, the tamarin (Callithrix jacchus), found in various locations throughout the State, but

Journal of Zoology, EarlyView.We explored age‐related cognitive decline in captive fawn‐footed mosaic‐tailed rats (Melomys cervinipes) using a novel object recognition task. Contrary to expectations, recognition memory did not decline with age, but recognition memory was lower in intermediate‐aged rats compared to both older and younger individuals.

Testicular Steroidogenesis in the Common Marmoset, Callithrix jacchus [PDF]
Biology of Reproduction, 1977 Testicualr steroidogenesis in Callithrix jacchus was investigated in order to determine whether a predominant delta-4 pathway with an accumulation of 17alpha-hydroxyprogesterone occurs. Testes were removed from a mature sexually active male marmoset durig the spring season.

American Journal of Primatology, Volume 88, Issue 7, July 2026.Lemur species respond differently to fire‐related vegetation changes (structure, species diversity) according to body size and ecological specialization in the dry deciduous forests of northwestern Madagascar. ABSTRACT Habitat quality is a key determinant of wildlife distribution. Fire degrades forests by increasing canopy openness and eliminating even

How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs
American Journal of Primatology, Volume 88, Issue 7, July 2026.Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,

Humanin Mitigates Aβ‐Induced Retinal Pigment Epithelium Injury via AMPK‐Beclin1‐Dependent Mitophagy
Aging Cell, Volume 25, Issue 7, July 2026.Humanin (HN) enhanced the clearance of Aβ‐accumulated mitochondria in the RPE while preserving retinal function and RPE barrier integrity. HN activated AMP‐activated protein kinase (AMPK), leading to phosphorylation of ULK1 and Beclin1, which promoted the interaction between Beclin1 and Parkin and their translocation to mitochondria.
