Future energy: in search of a scenario reflecting current and future pressures and trends

ABSTRACT: Growing societal pressures, technological trends and government and industry actions are moving the world toward decarbonization and away from the “business-as-usual”. As such, the concept of a single/obvious “business as usual” or “reference” scenario is no longer relevant. Instead, there are multiple plausible futures that should be explored. We contribute one such scenario that carefully considers emission-reduction trends and actions that are likely in the future, absent globally coordinated mitigation effort. We explore the long-term implications for energy, emissions, and temperature outcomes if the world continues to address climate change in the way it has so far—through piecemeal actions and growing social and technological pressures. This Growing Pressures scenario results in a central scenario outcome of about 3 °C of surface temperature warming, which is higher than the “well below 2 °C” level aspired by the Paris Agreement, but lower than many widely used “no-policy” scenarios. Ongoing and growing pressures of change, the roots of which are clearly visible today, could deliver a plausible energy transition scenario to near zero emissions that plays out over the coming century. While a more aggressive transition is clearly required, this finding highlights the need to bring actions forward in time to achieve an improved outcome making use of clearly identifiable policies and technologies.

Metastatic renal cell carcinoma: Current scenario and future trends.

Project description:An improved understanding of the biology of renal cell carcinoma (RCC) has led to the development of a number of targeted agents, which has resulted in a paradigm shift in the management of metastatic RCC. We review the current therapeutic strategies for metastatic RCC and present a synopsis of the novel agents in use today with a discussion of the phase III trials that demonstrated their clinical benefit. The management of RCC continues to evolve. The introduction of VEGF and mTOR inhibitors has markedly expanded our drug armamentarium and improved the outcome of a disease that has always been challenging to treat. Knowledge from upcoming trials will help us utilize these drugs for maximum clinical efficacy with optimal dosing and sequencing, either individually or in combination therapy.

Colorectal cancer vaccines: The current scenario and future prospects.

Project description:Colorectal cancer (CRC) is one of the most common cancers worldwide. Current therapies such as surgery, chemotherapy, and radiotherapy encounter obstacles in preventing metastasis of CRC even when applied in combination. Immune checkpoint inhibitors depict limited effects due to the limited cases of CRC patients with high microsatellite instability (MSI-H). Cancer vaccines are designed to trigger the elevation of tumor-infiltrated lymphocytes, resulting in the intense response of the immune system to tumor antigens. This review briefly summarizes different categories of CRC vaccines, demonstrates the current outcomes of relevant clinical trials, and provides particular focus on recent advances on nanovaccines and neoantigen vaccines, representing the trend and emphasis of CRC vaccine development.

Therapies for Type 1 Diabetes: Current Scenario and Future Perspectives.

Project description:Type 1 diabetes (T1D) is caused by autoimmune destruction of insulin-producing β cells located in the endocrine pancreas in areas known as islets of Langerhans. The current standard-of-care for T1D is exogenous insulin replacement therapy. Recent developments in this field include the hybrid closed-loop system for regulated insulin delivery and long-acting insulins. Clinical studies on prediction and prevention of diabetes-associated complications have demonstrated the importance of early treatment and glucose control for reducing the risk of developing diabetic complications. Transplantation of primary islets offers an effective approach for treating patients with T1D. However, this strategy is hampered by challenges such as the limited availability of islets, extensive death of islet cells, and poor vascular engraftment of islets post-transplantation. Accordingly, there are considerable efforts currently underway for enhancing islet transplantation efficiency by harnessing the beneficial actions of stem cells. This review will provide an overview of currently available therapeutic options for T1D, and discuss the growing evidence that supports the use of stem cell approaches to enhance therapeutic outcomes.

Allergen Immunotherapy: Current and Future Trends.

Project description:Allergen immunotherapy (AIT) is the sole disease-modifying treatment for allergic rhinitis; it prevents rhinitis from progressing to asthma and lowers medication use. AIT against mites, insect venom, and certain kinds of pollen is effective. The mechanism of action of AIT is based on inducing immunological tolerance characterized by increased IL-10, TGF-β, and IgG4 levels and Treg cell counts. However, AIT requires prolonged schemes of administration and is sometimes associated with adverse reactions. Over the last decade, novel forms of AIT have been developed, focused on better allergen identification, structural modifications to preserve epitopes for B or T cells, post-traductional alteration through chemical processes, and the addition of adjuvants. These modified allergens induce clinical-immunological effects similar to those mentioned above, increasing the tolerance to other related allergens but with fewer side effects. Clinical studies have shown that molecular AIT is efficient in treating grass and birch allergies. This article reviews the possibility of a new AIT to improve the treatment of allergic illness.

Paracoccidioidomycosis: Current Status and Future Trends.

Project description:Paracoccidioidomycosis (PCM), initially reported in 1908 in the city of São Paulo, Brazil, by Adolpho Lutz, is primarily a systemic and neglected tropical mycosis that may affect individuals with certain risk factors around Latin America, especially Brazil. Paracoccidioides brasiliensis sensu stricto, a classical thermodimorphic fungus associated with PCM, was long considered to represent a monotypic taxon. However, advances in molecular taxonomy revealed several cryptic species, including Paracoccidioides americana, P. restrepiensis, P. venezuelensis, and P. lutzii, that show a preference for skin and mucous membranes, lymph nodes, and respiratory organs but can also affect many other organs. The classical diagnosis of PCM benefits from direct microscopy culture-based, biochemical, and immunological assays in a general microbiology laboratory practice providing a generic identification of the agents. However, molecular assays should be employed to identify Paracoccidioides isolates to the species level, data that would be complemented by epidemiological investigations. From a clinical perspective, all probable and confirmed cases should be treated. The choice of treatment and its duration must be considered, along with the affected organs, process severity, history of previous treatment failure, possibility of administering oral medication, associated diseases, pregnancy, and patient compliance with the proposed treatment regimen. Nevertheless, even after appropriate treatment, there may be relapses, which generally occur 5 years after the apparent cure following treatment, and also, the mycosis may be confused with other diseases. This review provides a comprehensive and critical overview of the immunopathology, laboratory diagnosis, clinical aspects, and current treatment of PCM, highlighting current issues in the identification, treatment, and patient follow-up in light of recent Paracoccidioides species taxonomic developments.

Monoclonal Antibodies against SARS-CoV-2: Current Scenario and Future Perspectives.

Project description:Monoclonal antibodies (mAbs) have been known since the 1970s. However, their therapeutic potential in the medical field has recently emerged, with the advancement of manufacturing techniques. Initially exploited mainly in the oncology field, mAbs have become increasingly relevant in Infectious Diseases. Numerous mAbs have been developed against SARS-CoV 2 and have proven their effectiveness, especially in the management of the mild-to-moderate disease. In this review, we describe the monoclonal antibodies currently authorized for the treatment of the coronavirus disease 19 (COVID-19) and offer an insight into the clinical trials that led to their approval. We discuss the mechanisms of action and methods of administration as well as the prophylactic and therapeutic labelled indications (both in outpatient and hospital settings). Furthermore, we address the critical issues regarding mAbs, focusing on their effectiveness against the variants of concern (VoC) and their role now that a large part of the population has been vaccinated. The purpose is to offer the clinician an up-to-date overview of a therapeutic tool that could prove decisive in treating patients at high risk of progression to severe disease.

Design and Development of COX-II Inhibitors: Current Scenario and Future Perspective.

Project description:Innate inflammation beyond a threshold is a significant problem involved in cardiovascular diseases, cancer, and many other chronic conditions. Cyclooxygenase (COX) enzymes are key inflammatory markers as they catalyze prostaglandins production and are crucial for inflammation processes. While COX-I is constitutively expressed and is generally involved in "housekeeping" roles, the expression of the COX-II isoform is induced by the stimulation of different inflammatory cytokines and also promotes the further generation of pro-inflammatory cytokines and chemokines, which affect the prognosis of various diseases. Hence, COX-II is considered an important therapeutic target for drug development against inflammation-related illnesses. Several selective COX-II inhibitors with safe gastric safety profiles features that do not cause gastrointestinal complications associated with classic anti-inflammatory drugs have been developed. Nevertheless, there is mounting evidence of cardiovascular side effects from COX-II inhibitors that resulted in the withdrawal of market-approved anti-COX-II drugs. This necessitates the development of COX-II inhibitors that not only exhibit inhibit potency but also are free of side effects. Probing the scaffold diversity of known inhibitors is vital to achieving this goal. A systematic review and discussion on the scaffold diversity of COX inhibitors are still limited. To address this gap, herein we present an overview of chemical structures and inhibitory activity of different scaffolds of known COX-II inhibitors. The insights from this article could be helpful in seeding the development of next-generation COX-II inhibitors.

Divorce and health: current trends and future directions.

Project description:OBJECTIVE:Social relationships play a vital role in health and well-being, and it follows that loss experiences can be highly stressful for some people. This article reviews what is known about the association between marital separation, divorce, and health outcomes. METHODS:Key findings in the area of divorce and health are discussed, and the review outlines a series of specific questions for future research. In particular, the article integrates research in social epidemiology with research in social psychophysiology. The former approach provides a broad-based estimate of the association between marital status and health outcomes, whereas the latter approach studies mechanisms of action and individual differences associated with increased risk for poor outcomes. RESULTS:The experience of separation or divorce confers risk for poor health outcomes, including a 23% higher mortality rate. However, most people cope well and are resilient after their marriage or long-term relationship ends. Despite the fact that resilience is the most common response, a small percentage of people (approximately 10%-15%) struggle quite substantially, and it seems that the overall elevated adverse health risks are driven by the poor functioning of this group. Several candidate mechanisms and novel (ambulatory) assessment techniques that may elucidate the poor outcomes among people who adapt poorly to separation are discussed. CONCLUSIONS:To increase knowledge on the association between divorce and health, three primary areas require more research: a) genetic and third variable explanations for divorce-related health outcomes, (b) better studies of objective social behavior after separation, and (c) increased attention to interventions targeting high-risk adults.

Membrane Protein Crystallisation: Current Trends and Future Perspectives.

Project description:Alpha helical membrane proteins are the targets for many pharmaceutical drugs and play important roles in physiology and disease processes. In recent years, substantial progress has been made in determining their atomic structure using X-ray crystallography. However, a major bottleneck still remains; the identification of conditions that give crystals that are suitable for structure determination. Over the past 10 years we have been analysing the crystallisation conditions reported for alpha helical membrane proteins with the aim to facilitate a rational approach to the design and implementation of successful crystallisation screens. The result has been the development of MemGold, MemGold2 and the additive screen MemAdvantage. The associated analysis, summarised and updated in this chapter, has revealed a number of surprisingly successfully strategies for crystallisation and detergent selection.
