Formation and preservation of pores in deep limestone reservoirs: A case study of Upper Permian Changxing Formation, central Sichuan Basin, SW China

Petroleum Exploration and Development
In recent years, drilling data from wells Pengshen 10, Heshen 9, Tongshen 17 and Zhengyang 1 in the Sichuan Basin have confirmed the presence of a set of porous reef-beach limestone reservoirs in the Upper Permian Changxing Formation, which breaks the ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Advancing coral reef monitoring: a deep learning perspective on automated segmentation and classification

Discover Applied Sciences
In this study, we investigate the potential of computer vision and artificial intelligence techniques, particularly deep learning, to revolutionize coral reef monitoring. Traditional methods, relying heavily on manual assessments, are labor-intensive and

Histories in bone: Navigating the ethical landscape of human skeletal collections in South Africa

Anatomical Sciences Education, EarlyView.
Abstract Provenance is at the center of addressing the complicated ethical stewardship of legacy human skeletal collections. Many South African (SA) health science institutions have skeletal collections. While the history of the collections and the demographics of the skeletons have been reported, the provenance of the individuals within the ...

Deep reefs of the Great Barrier Reef offer limited thermal refuge during mass coral bleaching [PDF]

Nature Communications, 2018
AbstractOur rapidly warming climate is threatening coral reefs as thermal anomalies trigger mass coral bleaching events. Deep (or “mesophotic”) coral reefs are hypothesised to act as major ecological refuges from mass bleaching, but empirical assessments are limited. We evaluated the potential of mesophotic reefs within the Great Barrier Reef (GBR) and

Population pharmacokinetics of levofloxacin in breastmilk in patients with rifampicin‐resistant tuberculosis

British Journal of Clinical Pharmacology, EarlyView.
Levofloxacin is a widely used antibiotic included in rifampicin‐resistant tuberculosis (RR‐TB) treatment. Data describing levofloxacin concentrations in breastmilk and infant exposure are limited. We analysed data from two South African studies of breastfeeding women receiving levofloxacin (750–1000 mg daily) for RR‐TB.

Validating the deep reef refugia hypothesis

, 2015
In 1996 Peter Glynn first suggested corals maybe protected from impacts when found at depth. When this is the case deeper reefs maybe able to seed recovery in the shallows by providing a source of recruits. This is known as the deep reef refugia hypothesis while the deeper portions of coral reefs (30-100m deep) are now termed Mesophotic Coral ...

SCSFish2025: a large dataset from South China sea for coral reef fish identification

Scientific Reports
Coral reefs are one of the most biodiverse ecosystems on Earth and are extremely important for marine ecosystems. However, coral reefs are rapidly degrading globally, and for this reason, in-situ online monitoring systems are being used to monitor coral ...

A university‐certified course on dossier assessment for regulatory scientists in Africa—Reporting on our 5‐year experience

British Journal of Clinical Pharmacology, EarlyView.
Aim The shortage of trained clinical assessors in African National Regulatory Authorities (NRAs) poses a challenge to effective regulatory decision‐making. Developed in line with the World Health Organization's (WHO) Global Competency Framework (WHO‐GCF), a university‐certified short course, Dossier assessment for clinical assessors in Africa, was ...
