Metabolic reprogramming is the hallmark of malignant tumors. Both metabolic phenotype and metabolic dependence are changed during the development of cancer from precancerous tissue to local invasion to metastasis. Cancer cells autonomously alter their flux through various metabolic pathways in order to meet the increased bioenergetic and biosynthetic demand as well as mitigate oxidative stress required for cancer cell proliferation and survival. The change of the tumor microenvironment (TME) is a key factor driving tumor metabolic reprogramming. The tumor microenvironment denotes the non-cancerous cells and components presented in the tumor, including molecules produced and released by them....
We are delighted to present the 2022 Women in Chemistry article collection. Following the celebration of International Women’s Day 2022, the UNESCO International Day of Women and Girls in Science, Frontiers in Chemistry is proud to offer this platform to promote the work of women scientists, across all branches of Chemistry. At present, less than 30% of researchers worldwide are women. Long-standing biases and gender stereotypes are discouraging girls and women away from science-related fields, and STEM research in particular. Chemistry is no exception to this. Science and gender equality are, however, essential to ensure sustainable development as highlighted by UNESCO. In order to change traditional mindsets, gender equality must be promoted, stereotypes defeated, and girls and women should be encouraged to pursue STEM careers.
A common feature of cancer metabolism is the ability to obtain essential nutrients from a nutrient-poor environment and use them to maintain viability as well as generate new biomass. Alterations in intracellular and extracellular metabolites can be accompanied by tumor-associated metabolic reprogramming with profound effects on gene expression, cell differentiation, and tumor microenvironment. In these cases, the metabolic microenvironment of the tumor itself can present an immunosuppressive environment that needs to be overcome. Specifically, it will help maximize the efficacy of cancer therapies by identifying targets that suppress or alter cancer metabolism to improve the tumor microenvironment nutrient availability or that modulate immune metabolism to bolster inflammation.
This book illustrates how green nanotechnology is being used to promote sustainability, including applications in environmental remediation and energy optimization.
This book covers the photothermal effect of different categories of light-absorbing nanomaterials.
The exploration of photothermal nanomaterials with high light-to-heat conversion efficiency has paved the way for practical applications, including in cancer therapy, environmental remediation, catalysis, imaging and biomedicine. Covering the photothermal effect of different categories of light-absorbing nanomaterials, and focusing on metallic nanomaterials, 2D materials, semiconductors, carbon-based nanomaterials, polymeric nanomaterials and their composites, chapters in this book provide a systematic summary of recent advances in the fabrication and application of photothermal nanomaterials, discussing advantages, challenges and potential opportunities. This text will be a valuable resource for scientists working on photothermal nanomaterials, as well as those interested in the applications across chemistry, biomedicine, nanotechnology and materials science.
The first biographical dictionary in any Western language devoted solely to Chinese women, Biographical Dictionary of Chinese Women is the product of years of research, translation, and writing by scores of China scholars from around the world. Volume II: Twentieth Century includes a far greater range of women than would have been previously possible because of the enormous amount of historical material and scholarly research that has become available recently. They include scientists, businesswomen, sportswomen, military officers, writers, scholars, revolutionary heroines, politicians, musicians, opera stars, film stars, artists, educators, nuns, and more.
