Born Toon Soon: Preterm birth matters
Doc number: S1 Abstract: Urgent action is needed to address preterm birth given that the first country-level estimates show that globally 15 million babies are born too soon and rates are increasing in most countries with reliable time trend data. As the first in a supplement entitled \"Born Too Soon\", this paper focuses on the global policy context. Preterm birth is critical for progress on Millennium Development Goal 4 (MDG) for child survival by 2015 and beyond, and gives added value to maternal health (MDG 5) investments also linking to non-communicable diseases. For preterm babies who survive, the additional burden of prematurity-related disability may affect families and health systems. Prematurity is an explicit priority in many high-income settings; however, more attention is needed especially in low- and middle-income countries where the invisibility of preterm birth as well as its myths and misconceptions have slowed action on prevention and care. Recent global attention to preterm birth hit a tipping point in 2012, with the May 2 publication of Born Too Soon: The Global Action Report on Preterm Birth and with the 2nd annual World Prematurity Day on November 17 which mobilised the actions of partners in many countries to address preterm birth and newborn health. Interventions to strengthen preterm birth prevention and care span the continuum of care for reproductive, maternal, newborn and child health. Both prevention of preterm birth and implementation of care of premature babies require more research, as well as more policy attention and programmatic investment. Declaration: This article is part of a supplement jointly funded by Save the Children's Saving Newborn Lives programme through a grant from The Bill & Melinda Gates Foundation and March of Dimes Foundation and published in collaboration with the World Health Organization (WHO). The original article was published in PDF format in the WHO Report \"Born Too Soon: the global action report on preterm birth (ISBN 978 92 4 150343 30). The article has been reformatted for journal publication and has undergone peer review according to Reproductive Health 's standard process for supplements and may feature some variations in content when compared to the original report. This co-publication makes the article available to the community in a full-text format.

After a century of nisin research - where are we now?
It is almost a century since nisin was discovered in fermented milk cultures, coincidentally in the same year that penicillin was first described. Over the last 100 years this small, highly modified pentacyclic peptide has not only found success in the food industry as a preservative but has also served as the paradigm for our understanding of the genetic organization, expression, and regulation of genes involved in lantibiotic biosynthesis—one of the few cases of extensive post-translation modification in prokaryotes. Recent developments in understanding the complex biosynthesis of nisin have shed light on the cellular location of the modification and transport machinery and the co-ordinated series of spatio-temporal events required to produce active nisin and provide resistance and immunity. The continued unearthing of new natural variants from within human and animal gastrointestinal tracts has sparked interest in the potential application of nisin to influence the microbiome, given the growing recognition of the role the gastrointestinal microbiota plays in health and disease. Moreover, interdisciplinary approaches have taken advantage of biotechnological advancements to bioengineer nisin to produce novel variants and expand nisin functionality for applications in the biomedical field. This review will discuss the latest progress in these aspects of nisin research.
The highly post-translationally modified peptide nisin has been studied over the course of the last 100 years, and although it has been employed successfully as a food preservative, its potent activity against multidrug resistant microbes, long safety record, lack of any significant resistance development, and amenability to bioengineering approaches to improve its antimicrobial and physicochemical properties has meant that the focus on nisin-related research is shifting from food preservation towards therapeutic use for the treatment of bacterial infections.

Pathogenesis and treatment of depression; role of diet in prevention and therapy. Review
In recent years, there has been a significant increase in the incidence of depression, which is related to, inter alia, the COVID-19 pandemic. Depression can be fatal if not treated or treated inappropriately; is the main cause of suicide attempts. The disease is multifactorial, and pharmacotherapy often fails to bring satisfactory results. Therefore, more and more importance is attached to the natural healing substances and nutrients contained in food. They can significantly affect the process of therapy and prevention of depressive disorders. A proper diet plays a very important role in the prevention of depression and can be a valuable addition to psychological and pharmacological treatment. In turn, an inadequate diet may reduce the effectiveness of antidepressants or may increase their side effects, leading to life-threatening symptoms. The work is a review of the literature on the pathogenesis of the development and treatment of depression, with particular emphasis on dietary supplements and the role of nutrition in the prevention and treatment of depressive disorders.

Making our democracy work : a judge's view
Justice Breyer discusses what the Court must do going forward to maintain that public confidence and argues for interpreting the Constitution in a way that works in practice. He forcefully rejects competing approaches that look exclusively to the Constitution's text or to the eighteenth-century views of the framers. Instead, he advocates a pragmatic approach that applies unchanging constitutional values to ever-changing circumstances--an approach that will best demonstrate to the public that the Constitution continues to serve us well.-- Source other than Library of Congress.

Radiotherapy remodels the tumor microenvironment for enhancing immunotherapeutic sensitivity
Abstract Cancer immunotherapy has transformed traditional treatments, with immune checkpoint blockade being particularly prominent. However, immunotherapy has minimal benefit for patients in most types of cancer and is largely ineffective in some cancers (such as pancreatic cancer and glioma). A synergistic anti-tumor response may be produced through the combined application with traditional tumor treatment methods. Radiotherapy (RT) not only kills tumor cells but also triggers the pro-inflammatory molecules’ release and immune cell infiltration, which remodel the tumor microenvironment (TME). Therefore, the combination of RT and immunotherapy is expected to achieve improved efficacy. In this review, we summarize the effects of RT on cellular components of the TME, including T cell receptor repertoires, different T cell subsets, metabolism, tumor-associated macrophages and other myeloid cells (dendritic cells, myeloid-derived suppressor cells, neutrophils and eosinophils). Meanwhile, non-cellular components such as lactate and extracellular vesicles are also elaborated. In addition, we discuss the impact of different RT modalities on tumor immunity and issues related to the clinical practice of combination therapy.
