Book Description
A clinical psychiatrist explores the effects of DMT, one of the most powerful psychedelics known. • A behind-the-scenes look at the cutting edge of psychedelic research. • Provides a unique scientific explanation for the phenomenon of alien abduction experiences. From 1990 to 1995 Dr. Rick Strassman conducted U.S. Government-approved and funded clinical research at the University of New Mexico in which he injected sixty volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an extraordinarily riveting inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical found in the psychedelic Amazon brew, ayahuasca, is also manufactured by the human brain. In Strassman's volunteers, it consistently produced near-death and mystical experiences. Many reported convincing encounters with intelligent nonhuman presences, aliens, angels, and spirits. Nearly all felt that the sessions were among the most profound experiences of their lives. Strassman's research connects DMT with the pineal gland, considered by Hindus to be the site of the seventh chakra and by Rene Descartes to be the seat of the soul. DMT: The Spirit Molecule makes the bold case that DMT, naturally released by the pineal gland, facilitates the soul's movement in and out of the body and is an integral part of the birth and death experiences, as well as the highest states of meditation and even sexual transcendence. Strassman also believes that "alien abduction experiences" are brought on by accidental releases of DMT. If used wisely, DMT could trigger a period of remarkable progress in the scientific exploration of the most mystical regions of the human mind and soul.

Book Description
Gastroesophageal cancer is among the most common malignant diseases worldwide and is associated with high mortality rates, leading to a substantial burden on public health and healthcare systems around the world. Chemotherapeutic drugs have achieved great success in the treatment of esophageal cancer; however, they also bring cytotoxicity to other organs and often have serious side effects. With the development of molecular diagnostics and biomarker discovery, the application of precision medicine has emerged to improve clinical outcomes. New antineoplastic therapy development is a timely topic in light of the recent development of precision medicine. New biotherapies aim to inhibit or regulate different targets, which are thought to be functionally selective or overexpressed in some types of tumors. In particular, progress has been made to understand the molecular biology of gastrointestinal cancer, resulting in the discovery of various molecular targets, such as KRAS, PD-1, PD-L1, EGFR, HER2 and VEGF. Moreover, anticancer agents, such as pembrolizumab, olaparib, trastuzumab, bevacizumab, either as single agents or in combination with conventional chemotherapy, have become part of the standard of care for treatment of advanced gastroesophageal cancer. This Research Topic provides a platform for recent studies on novel molecular targets and treatments for gastroesophageal cancer. Both Original Research articles and Reviews are welcome. Subjects may include but are not limited to: 1) Oncogenes and tumor suppressors; 2) Drug sensitivity/resistance; 3) Tumor metastasis and tumor microenvironment; 4) Biomarker discovery and epigenetic regulation.

Book Description
A million cells in our bodies die every second--they commit suicide by activating a process called apoptosis or other forms of programmed cell death. These mechanisms are essential for survival of the body as a whole and play critical roles in various developmental processes, the immune system, and cancer. In this second edition of Douglas Green's essential book on cell death, Green retains the bottom-up approach of the first edition, starting with the enzymes that carry out the execution (caspases) and their cellular targets before examining the machinery that connects them to signals that cause cell death. He also describes the roles of cell death in development, neuronal selection, and the development of self-tolerance in the immune system, as well as how the body uses cell death to defend against cancer. The new edition is fully updated to cover the many recent advances in our understanding of the death machinery and signals that control cell death. These include the mechanisms regulating necroptosis, mitophagy, and newly identified processes, such as ferroptosis. The book will thus be of great interest to researchers actively working in the field, as well as biologists and undergraduates encountering the topic for the first time.

Book Description
Gastric cancer (GC) represents a serious health problem on a global scale. Despite some recent advances in the field, the prognosis in GC remains poor. A better understanding of molecular biology, which would lead to improved treatment options, is needed. Many potential biomarkers of prognostic significance have been identified. However, inhibition of only HER2 protein has led to a modest survival benefit. A deeper understanding of the pathogenesis and biological features of gastric cancer, including the identification and characterization of diagnostic, prognostic, predictive, and therapeutic biomarkers, hopefully will provide improved clinical outcomes. This Research Topic aims to provide a comprehensive overview on recent progress in emerging molecular biomarkers for gastric cancer. We welcome the submission of Review and Original Research articles covering, but not limited to, the following topics: 1)Novel diagnostic molecules to improve the early detection rate for gastric cancer 2)Novel prognostic molecules to stratify gastric cancer patients into different risk 3)Novel therapeutic biomarker which could serve as target for treating gastric cancer 4)Novel biomarker to predict chemotherapy response of gastric cancer patients

Book Description
Calibrating phylogenies to time is central to addressing many questions in evolutionary biology and macroevolution. The fossil record once provided our only source for establishing a timeline for evolution. However, the incompleteness of the fossil record and the non-uniformity of fossil recovery rate make it challenging to obtain precise estimates of divergence times from fossil evidence alone. Molecular dating, which combines evidence from the geological and molecular records, enables us to generate a much more complete and precise timeline of events. The molecular clock can be time-calibrated using temporal evidence from fossils and used to estimate divergence times based on the assumption that the rate of sequence evolution will be approximately constant over time and among lineages. Methodological challenges to applying this concept in practice have been to relax the assumption of constant evolutionary rates and to model the uncertainty associated with paleontological and geological calibrations. To this end, available statistical methods have become increasingly complex in order to capture key features of empirical data. These are typically applied using Bayesian inference, which provides a powerful framework for incorporating multiple sources of uncertainty. Although overall more effort has been expended in developing models of molecular sequence evolution, critical advances have also included approaches to modeling taxonomic diversification and fossilization. In particular, recent advances in birth-death process models have allowed for continuous sampling along lineages, enabling more information from the fossil record to be incorporated into dating analyses in a statistically coherent way. In addition, available dating methods can now be applied to scenarios in which no molecular data may be available, allowing for novel insights into the evolution of entirely extinct clades. Other recent innovations enable us to date divergence times among taxa that have no fossil record, including the use of gene duplication events or biogeographic evidence. Furthermore, time-calibrated trees are necessary for obtaining phylogenetic estimates of taxonomic diversification and extinction rates, which can now be jointly inferred along with lineage divergence times. These approaches offer an exciting opportunity to understand the evolution of life in deep time, although key challenges remain, especially with regards to modeling the processes of genome evolution, taxonomic diversification and fossil recovery. In this Research Topic, we focus on recent advances in methodology, outstanding challenges, and the application of molecular and paleontological dating methods to empirical case studies across the Tree of Life.
