Rats kept on a standard diet were subdivided into several experimental groups: group 1, control; group 2, animals receiving ethyl alcohol for 10 days; group 3, animals receiving ethyl alcohol for 3 months; group 4, animals receiving colchicine; group 5, animals receiving alcohol in combination with colchicine; group 6, animals receiving alcohol in combination with carbon tetrachloride (CCl4); and group 7, animals receiving alcohol in combination with CCl4 and colchicine. Electron microscopy of the rat liver has shown that colchicine inhibited significantly the onset of hepatic fibrosis and degenerative changes in hepatocyte organells induced by hepatotoxins (alcohol alone or alcohol in combination with CCl4). Colchicine also inhibited monooxygenase activity in the liver homogenate of experimental rats. Possible mechanisms of hepatoprotective colchicine effect are discussed.

Speciation research represents our thinking and exploration about how new species are generated and maintained, and it is one of the most important parts of evolutionary biology. Revealing new species formation modes, processes of reproductive isolation establishment and their intrinsic genetic mechanisms, are not only important issues and primary tasks in the field of speciation, but also the key clues for our understandings about the species diversity in nature. Here, by focusing on animal groups, we first introduced different definitions of species concept, and then summarized present research progress and important breakthroughs made in the speciation modes and molecular mechanism of reproductive isolation.

It has been more than 40 years since the beginning of exploring the genetic composition of ancient organisms from the perspective of ancient DNA. In the recent 20 years, with the development and application of high-throughput sequencing technology platforms and the improved efficiency of retrieving highly fragmented DNA molecules, ancient DNA research moved forward to a brand-new era of deep-time paleogenomics. It not only solved many controversial phylogenetic problems, enriched the migration and evolution details of various organisms including humans, but also launched exploration of the molecular responses to climate changes in terms of "whole genomic-big data-multi-species" level.

Subarachnoid hemorrhage (SAH), a prevalent cerebrovascular condition associated with a high mortality rate, frequently results in neuronal apoptosis and an unfavorable prognosis. The adjunctive use of traditional Chinese medicine (TCM) with surgical interventions exerts a therapeutic impact on SAH, potentially by facilitating apoptosis. However, the mechanism by which TCM mediates apoptosis following SAH remains unclear.

Introduction: Atopic dermatitis (AD) is a common and relapsing skin disease characterized by skin barrier dysfunction, inflammation, and chronic pruritus. Both cutaneous barrier dysfunction and immune dysregulation are critical etiologies of the pathology of AD. Although various anti-inflammatory pharmacological agents, including cytokine inhibitors and signaling pathway blockers, have been developed recently, keeping the skin clean is of utmost importance in maintaining physiological cutaneous barrier function and avoiding an AD flare.
