Evolution of major histocompatibility complex class I and class II genes in the brown bear [PDF]

open access: yes, 2012
International audienceBackground: Major histocompatibility complex (MHC) proteins constitute an essential component of the vertebrate immune response, and are coded by the most polymorphic of the vertebrate genes. Here, we investigated sequence variation

Characterization and Analysis of Whole Transcriptome of Giant Panda Spleens: Implying Critical Roles of Long Non-Coding RNAs in Immunity

open access: yesCellular Physiology and Biochemistry, 2018
Background/Aims: Giant pandas, an endangered species, are a powerful symbol of species conservation. Giant pandas may suffer from a variety of diseases. Owing to their highly specialized diet of bamboo, giant pandas are thought to have a relatively weak ...

Rapid changes in Atlantic grey seal milk from birth to weaning – immune factors and indicators of metabolic strain [PDF]

open access: yes, 2017
True seals have the shortest lactation periods of any group of placental mammal. Most are capital breeders that undergo short, intense lactations, during which they fast while transferring substantial proportions of their body reserves to their pups ...

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

open access: yesBoreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

Report on the Middle Pleistocene and Early Holocene vertebrate fauna of Maoshan locality, Lipu, Guangxi

open access: yesCarsologica Sinica
Karst caves in Guangxi contain a large number of Quaternary vertebrate fossils; however, research on taxonomy and biostratigraphy remains insufficient. Therefore, more detailed reports on fossil assemblages are essential.

Sequence analysis of the ATP synthase of subunits (ATP8 and ATP6) genes of mitochondrial DNA genome from Ailuropoda melanoleuca

open access: yesMitochondrial DNA. Part B. Resources, 2018
To explore the effects of the mutations of ATP6 and ATP8 genes on energy metabolism and genetic structure, we sequenced the ATP6 and ATP8 genes of Ailuropoda melanoleuca.

Wolf howls encode both sender- and context-specific information [PDF]

open access: yes, 2018
Loud, long-distance calls serve varied functions across animal species including marking territory, attracting mates and signalling one's identity. Here, we examined the types of sender- and context-specific information encoded in the howls of captive ...

Transesophageal Echocardiography Examination in Ailuropoda melanoleuca.

open access: yesAsian journal of anesthesiology, 2020
Cardiac function analysis for Ailuropoda melanoleuca, also called giant panda, with transthoracic echocardiography has several limitations, such as limited probe position area and poor echo window. We want to determine the feasibility of transesophageal echocardiography (TEE) for cardiac examination in Ailuropoda melanoleuca.Eight-year-old male ...

Microbial Contributions to Primate Reproduction

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Reproduction is a complex process, and microbes play a far greater role than previously imagined. This review explores the ways that microbiomes influence the rich tapestry of reproductive processes and outcomes within the primate lineage, including pre‐copulatory and post‐copulatory mechanisms.

Fatal Toxoplasma gondii infection in the giant panda

open access: yesParasite, 2015
Toxoplasma gondii can infect nearly all warm-blooded animals. We report an acute fatal T. gondii infection in the endangered giant panda (Ailuropoda melanoleuca) in a zoo in China, characterized by acute gastroenteritis and respiratory symptoms.
