The effects of warming on loggerhead turtle nesting counts.

Global trends in marine turtle nesting numbers vary by region, influenced by environmental or anthropogenic factors. Our study investigates the potential role of past temperature fluctuations on these trends, particularly whether warmer beaches are linked to increased nesting due to higher female production (since sea turtles have temperature-dependent sex determination). We selected the loggerhead turtle (Caretta caretta) due to its wide distribution, strong philopatry and vulnerability to environmental changes.

Recent advances in recombinant production of soluble proteins in E. coli.

Background: E. coli still remains the most commonly used organism to produce recombinant proteins in research labs. This condition is mirrored by the attention that researchers dedicate to understanding the biology behind protein expression, which is then exploited to improve the effectiveness of the technology.

Dynamic PRC1-CBX8 stabilizes a porous structure of chromatin condensates.

The compaction of chromatin is a prevalent paradigm in gene repression. Chromatin compaction is commonly thought to repress transcription by restricting chromatin accessibility. However, the spatial organization and dynamics of chromatin compacted by gene-repressing factors are unknown.

Thoracoabdominal chordoma in a pediatric patient. A rare entity.

Introduction: Chordoma is a rare, slow-growing notochordal neoplasm typical of adults. Less than 5% of the cases occur in children, where they are located at the skull base. Treatment involves surgical resection with or without radiotherapy.

Nocardiosis in domestic ferrets (Mustela putorius furo).

Nocardia spp are ubiquitous, gram-positive, variably acid-fast, branching and beaded filamentous, facultative intracellular bacteria that are resistant to phagocytosis and can cause localized or systemic disease in a variety of mammals, including humans, as well as in birds, fish and reptiles. Seventeen pet domestic ferrets (Mustela putorius furo) were diagnosed with nocardiosis by several methods including cytological evaluation, histopathology, Ziehl-Neelsen staining and polymerase chain reaction (PCR). All except two ferrets were 2 years old or older at the time of clinical presentation.
