A review of carbonates as hydrocarbon source rocks: basic geochemistry and oil–gas generation
Petroleum Science, 2019 Carbonates have been known to act as hydrocarbon source rocks, but their basic geochemical and associated hydrocarbon generation characteristics remain not well understood as they occur with argillaceous source rocks in most cases, and the hydrocarbon ...

Review and prospect of research on the role of micro-organisms in karst carbon cycle
Carsologica Sinica, 2022 The issue of global climate change has drawn much attention to the research on the carbon cycle of karst systems. Carbonate rock is the largest known carbon pool on the earth.

Arthritis Care &Research, Accepted Article.Objective Routine liver enzyme monitoring is advocated while on allopurinol but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzymes in gout patients commenced on allopurinol. Methods 150 patients with gout and normal baseline serum aminotransferases initiated on allopurinol were followed ...
