As a noted author of childbirth education articles, books, and videotapes, Penny Simkin muses over the changes in maternity care during her career and the lessons she has learned. She searches for reasons to keep on working to bring normal birth to women, especially in an era when medical intervention based on editorials rather than evidence continue to increase.

Context: "Nanostructure of graphene-reinforced with polymethyl methacrylate" (PMMA-G), and vice versa, is investigated using its molecular structure, in the present work. The PMMA-G nanostructure was constructed by bonding PMMA with graphene nanosheet in a sense to get three different configurations. Each configuration consisted of polymeric structures with three degrees of polymerization (such as monomers, dimers, and trimers polymers, respectively).

The reduction of CO2 to CO provides a promising approach to the production of valuable chemicals through CO2 utilization. However, challenges persist with the rapid deactivation and insufficient activity of catalysts. Herein, we developed a soft-hard dual-template method to synthesize layered MoS2 using inexpensive and scalable templates, enabling facile regulation of sulfur vacancies by controlling the number of layers.

The gut microbiota is unanimously acknowledged as playing a central role in human health, notably through the production of various metabolites, including short-chain fatty acids, secondary bile acids, vitamins or neurotransmitters. Beyond contributing to gut health itself, these microbial metabolites significantly impact multiple organ systems by participating in key signaling pathways along the well documented gut-organ axes. Chemicals ingested through food might interact with our gut microbiota, altering metabolites production with consequences on health.

Aims: To reveal clinicopathological characteristics of alcoholic foamy degeneration (AFD)-an uncommon form of alcoholic liver injury.
Methods: Clinicopathological features of AFD (n=9) were examined in comparison to those of severe alcoholic hepatitis (SAH; n=12).
Results: Patients with AFD presented with either biochemical liver dysfunction (n=1) or clinical jaundice (n=8).
