Hemophilia A arises from mutations in the F8 gene, affecting ~ 1/5000 males. Treatment options include frequent intravenous factor and subcutaneous non-factor therapies. While these approaches have been widely used, they have significant limitations, such as breakthrough bleeds and joint disease due to suboptimal adherence, non-ideal factor kinetics, inhibitor generation, (Weyand, Blood 2018) as well as risk of thrombotic events and coagulation test interference with newer non-factor therapies.

Abstract:
Protein corona formation is critical for the design of ideal and safe nanoparticles (NPs) for nanomedicine, biosensing, organ targeting, and other applications, but methods to quantitatively predict the formation of the protein corona, especially for functional compositions, remain unavailable. The traditional linear regression model performs poorly for the protein corona, as measured by R2 (less than 0.40). Here, the performance with R2 over 0.75 in the prediction of the protein corona was achieved by integrating a machine learning model and meta-analysis. NPs without modification and surface

Transgenic animal bioreactors can produce therapeutic proteins with high value for pharmaceutical use.

Abstract:
The behavior of proteins near interfaces is relevant for biological and medical purposes. Previous results in bulk show that, when the protein concentration increases, the proteins unfold and, at higher concentrations, aggregate. Here, we study how the presence of a hydrophobic surface affects this course of events. To this goal, we use a coarse-grained model of proteins and study by simulations their folding and aggregation near an ideal hydrophobic surface in an aqueous environment by changing parameters such as temperature and hydrophobic strength, related, e.g., to ions concentration.

Abstract:
AbstractBoth poultry meat and eggs provide high-quality animal protein [containing sufficient amounts and proper ratios of amino acids (AAs)] for human consumption and, therefore, play an important role in the growth, development, and health of all individuals. Because there are growing concerns about the suboptimal efficiencies of poultry production and its impact on environmental sustainability, much attention has been paid to the formulation of low-protein diets and precision nutrition through the addition of low-cost crystalline AAs or alternative sources of animal-protein feedstuffs. This necessitates a better understanding of AA nutrition and metabolism in chickens. Although historic nutrition research has focused on nutritionally essential amino acids (EAAs) that are not synthesized or are inadequately synthesized in the body, increasing evidence shows that the traditionally classified nutritionally nonessential amino acids (NEAAs), such as glutamine and glutamate, have physiological and regulatory roles other than protein synthesis in chicken growth and egg production. In addition, like other avian species, chickens do not synthesize adequately glycine or proline (the most abundant AAs in the body but present in plant-source feedstuffs at low content) relative to their nutritional and physiological needs. Therefore, these two AAs must be sufficient in poultry diets. Animal proteins (including ruminant meat &amp; bone meal and hydrolyzed feather meal) are abundant sources of both glycine and proline in chicken nutrition. Clearly, chickens (including broilers and laying hens) have dietary requirements for all proteinogenic AAs to achieve their maximum productivity and maintain optimum health particularly under adverse conditions such as heat stress and disease. This is a paradigm shift in poultry nutrition from the 70-year-old “ideal protein” concept that concerned only about EAAs to the focus of functional AAs that include both EAAs and NEAAs.

Abstract:
This chapter takes up the public narrative of ‘We, the multitude of Europe’, which suggests that the only hope for progressive change in the EU lies in a politics of disruption, and asks whether this idea can be defended based on a systematic model. To that end, it resorts to the political theory of destituent power, according to which opposition to or withdrawal from public authority can function as a legitimate trigger for constitutional change. Distinguishing between anti-juridical and juridical conceptions of destituent power, the chapter discusses to what extent the disruptive political strategies put forward by protest movements in the EU can be regarded as justifiable. Focusing on the juridical strand as the more plausible one, it argues that ideas of destituent power as ‘state civil disobedience’ run into a problem of authorization. By contrast, popular sovereignty-based approaches illuminate a neglected dimension of constituent power: the right to dismantle public authorities without the intention to create new ones. While such a model of destituent power in part captures the actions and demands of EU protest movements, it can only complement, not replace, the constructive side of constituent power.

Abstract:
Terrorism is a significant concern worldwide. Criminals, jihadists, and terrorists are quick to use technology to protect their anonymity, privacy, modes of operation, and secret antisocial plans. They adapt to new innovations and exploit any technological advantages as means to ends. Clandestine operations are used to raise funds. Criminals, jihadists, and terrorists are working in international cells and rings that contest geographical boundaries and that require large resources and international security cooperation to obstruct their activities. Addressing these cross-country challenges require cross-country cooperation. The aim of this essay is to analyze the role of Internet intermediaries in countering online terror. I argue that Internet intermediaries can and should do far more than what they do to proactively fight online terrorism and that self-regulation is not effective enough. It is time for governments to step in and to protect vulnerable third parties by demanding that Internet intermediaries be vigilant and proactive in fighting terror. The idea of a new browser, CleaNet, is proposed to ensure a safe environment for Net users and for society at large.

Turtles and their eggs have long served as an important source of food for humans—almost certainly since very early in the evolution of the hominid lineage, and surely for at least the last 20,000 years (Nicholls, 1977).

Skeletal evidence of river turtles, in particular from such locations as Mohenjodaro and Harappa in the Indus Valley (e.g., Indian narrow-headed softshells and river terrapins), Mayapan, and many other Mesoamerican Mayan sites (e.g., Central American river turtles), and Naga ed-Der of Upper Ancient Egypt (e.g., Nile softshell) suggest that river turtles have helped to support the rise of the world's great civilizations as well (de Treville, 1975; Nath, 1959 in Groombridge &amp; Wright, 1982; Das, 1991; Lee, 1996). Their role continues and, in fact, has expanded as human populations have burgeoned and spread throughout the modern world. River turtles have always been too convenient and succulent a source of protein to ignore. Often large, fecund, and easily collected with simple techniques and equipment, especially in communal nesters which may concentrate at nesting sites in helpless thousands (at least formerly), river turtles are ideal prey. Much of the harvesting has been, and continues to be, conducted in relative obscurity in many parts of the world. Occasionally, however, the sheer magnitude of the resource and its slaughter has attracted the attention of literate observers, such as the early explorer-naturalists of the New and Old World tropics. Their accounts have given us some idea of the former truly spectacular abundance of some riverine species, and the equally spectacular levels of consistent exploitation which have brought them to their modern, much-diminished condition. Summaries of the exploitation of the two best documented examples of destruction of formerly abundant riverine species, the Asian river terrapin, and the giant South American river turtle, are provided under their appropriate geographic sections below.

Abstract:
The desire to protect the natural environment and the resources it hosts is at the core of every country's ambition to achieve long-term sustainable development. Yet, the history of development shows that environmental protection always came about as an after the fact activity. Nations around the world, including the industrial countries, most of the time reacted to adverse impacts of the environment rather than acting proactively to prevent undesirable outcomes of development. The 1970s decade is seen as a watermark in the development of legislation aimed at protecting the environment particularly in the developed world. This development and requirement to have projects subjected to environmental impact assessments spread to developing countries like Botswana in the 1980s. Botswana embraced the ideal to protect the environment to achieve sustainable development. Toward this end, the government of Botswana carried out Environmental Impact Assessment (EIA) on major projects voluntarily, even before the passing of the maiden EIA Act of 2005 and its supplement of 2011 and accompanying guidelines in 2012. After this and particularly in the 1990s, Botswana rigorously pursued its position on the international terrain where the country signed and ratified some international conventions and protocols. This chapter concludes by suggesting that the next area of focus for Botswana is on monitoring the outcomes of projects for which EIAs have been conducted.

Abstract:
Antibacterial and antifungal agents aim to kill pathogens, or at the very least incapacitate them. To achieve this aim these agents must have a reasonable degree of toxicity at the cellular level. If this toxicity was equally manifest against all cell types then the drugs would be unusable in patients as the side effect profile would be unacceptably severe. Selective toxicity, whereby the agents are orders of magnitude more toxic to bacteria or fungi than human cells, allows for the safe and effective administration of these agents to patients. There are a number of different mechanisms by which an antimicrobial agent can yield selective toxicity: ● Target a cellular structure that exists only in bacteria/fungi—e.g. the cell wall; ● Target a cellular structure that has a significantly different structure in bacteria/ fungi— e.g. the ribosome; the fungal cell membrane; ● Target cellular enzymes that are significantly different in bacteria/fungi e.g. topoisomerase; ● Target a synthetic pathway that exists only in bacteria e.g. folate synthesis. Broadly, antibacterial drugs can be divided into the following categories: ● Agents that target the cell wall; ● Agents that target the cell membrane; ● Agents that inhibit protein synthesis; ● Agents that inhibit DNA replication/ transcription of RNA; ● Agents that target folate synthesis; ● Agents that directly damage intracellular structures. The cell wall is unique to bacteria, and therefore an ideal target. Disrupting the complex cross-linking process required to produce the cell wall leads to loss of bacterial cell integrity and therefore to cell death. The following classes of antibiotics target the cell wall: The first class to be discovered, and still in many cases the most effective, incorporates the four-membered beta-lactam ring—its homology to d-alanyl-d-alanine allows beta-lactam-containing compounds to bind to cell wall peptidoglycans and act as chain terminators. The beta-lactam ring is fused to a five-membered sulphur-containing ring. Variations in side chains account for the differing pharmacokinetics and spectra of action of the different compounds—for example, the addition of an amino group to benzylpenicillin produces ampicillin.

Abstract:
This chapter examines the importance of ideas of nature to how people in Spey Bay think about the relationship between maternal bonding and gender differences in parenting. It begins by outlining two women's experiences of giving birth that illustrate their ambivalence about medical and technological intervention in the birth process and, specifically, the importance of naturalness, knowledge, and care in their aspirations for a good birth. It then considers the ethics of care and responsibility in parenthood, along with people's experiences and observations about the maternal bond and specifically its relationship to bodily experience. In discussing maternal bonding, people were rarely specific about which particular aspects of biological motherhood led to the formation of a maternal bond. In seeking to protect “nature” and “natural” reproduction, people can end up protecting and reproducing established norms of gender and sexuality.

Abstract:
In a proton exchange membrane fuel cell (PEMFC), humidification of reactant gases must be carefully optimized. Extremes in humidity levels at the low end (membrane dehydratation) and at the high end of the range (cathode flooding) can seriously reduce PEMFC performances. Various devices already exist to humidify and to adjust the temperature of gas streams. Criteria for the evaluation of their performances depend on the technology and/or differ from one manufacturer to the other, which makes comparison difficult. A fortiori, there is no consensus regarding their ideal values and no general met
