Polysaccharide-based nanomedicines for cancer immunotherapy: a review

Cancer immunotherapy is an effective antitumor approach through activating immune systems to eradicate tumors by immunotherapeutics. However, direct administration of “naked” immunotherapeutic agents (such as nucleic acids, cytokines, adjuvants or antigens without delivery vehicles) often results in: (1) an unsatisfactory efficacy due to suboptimal pharmacokinetics; (2) strong toxic and side effects due to low targeting (or off-target) efficiency. To overcome these shortcomings, a series of polysaccharide-based nanoparticles have been developed to carry immunotherapeutics to enhance antitumor immune responses with reduced toxicity and side effects. Polysaccharides are a family of natural polymers that hold unique physicochemical and biological properties, as they could interact with immune system to stimulate an enhanced immune response. Their structures offer versatility in synthesizing multifunctional nanocomposites, which could be chemically modified to achieve high stability and bioavailability for delivering therapeutics into tumor tissues. This review aims to highlight recent advances in polysaccharide-based nanomedicines for cancer immunotherapy and propose new perspectives on the use of polysaccharide-based immunotherapeutics.info:eu-repo/semantics/publishedVersio

Global Infectious Diseases in August 2023: A Monthly Analysis

Infectious diseases frequently affect children and adults worldwide. Owing to their specific biology and mode of transmission, the presence of infected individuals or carriers in a region often leads to outbreaks of the disease in that region, and in severe cases, to the death of the infected individual. Infectious diseases have been one of the main causes of mass disability or death in humans for centuries. Surveillance of infectious diseases on a continental scale is therefore important for assessing, recognizing, and preventing the risks that these diseases may pose to animal and human health on a global scale. This report focuses on global infectious disease outbreaks and systematically summarises the timing and location of outbreaks in infected populations between 24 July and 23 August 2023 based on the Global Outbreak Information Surveillance System (GOSIS) of Shusi Technologies

Global Infectious Diseases in February 2023: Monthly Analysis

Public health security in human societies is placed under enormous strain by infectious disease epidemics. According to the WHO, COVID-19 and Mpox remain on the list of PHEICs, whereas cholera, dengue, and other contagious diseases remain endemic in several countries and regions. Data on prevalent infectious diseases have been collected worldwide in recent weeks, and may provide new ideas for international collaboration in public health

Global Infectious Diseases in March 2023: Monthly Analysis

Infectious diseases pose a major burden on public health and economic stability among societies worldwide. For centuries, they have been among the leading causes of death and disability, and are currently presenting growing challenges to health security and human progress. This report focuses on global outbreaks of infectious diseases, relying on Shusi Tech’s Global Epidemic Information Monitoring System to systematically summarize outbreak timing and location in infected populations from February 24, 2023, to March 23, 2023. Therefore, surveillance of infectious diseases on a continental scale is important to assess, recognize and protect against the risks that these diseases may pose to animal, domestic animal and human health on a global scale

Global Infectious Diseases in January 2023: Monthly Analysis

Infectious diseases are a major threat to global health and the economic stability of societies worldwide. To prevent outbreaks, monitoring the growth trends of infectious diseases appears to be particularly important and necessary. Herein, data from epidemiological websites, such as the World Health Organization and National Health Council are used to illustrate the outbreak trends for infectious diseases worldwide. In the context of the COVID-19 pandemic, a global resurgence in other infectious diseases has been observed, particularly influenza in the United States. Proper surveillance and effective strategies are urgently required to keep emerging infectious diseases under control

Deciphering the genome structure and paleohistory of _Theobroma cacao_

We sequenced and assembled the genome of _Theobroma cacao_, an economically important tropical fruit tree crop that is the source of chocolate. The assembly corresponds to 76% of the estimated genome size and contains almost all previously described genes, with 82% of them anchored on the 10 _T. cacao_ chromosomes. Analysis of this sequence information highlighted specific expansion of some gene families during evolution, for example flavonoid-related genes. It also provides a major source of candidate genes for _T. cacao_ disease resistance and quality improvement. Based on the inferred paleohistory of the T. cacao genome, we propose an evolutionary scenario whereby the ten _T. cacao_ chromosomes were shaped from an ancestor through eleven chromosome fusions. The _T. cacao_ genome can be considered as a simple living relic of higher plant evolution

Global Infectious Diseases in April 2023: Monthly Analysis

Thousands of years have passed since infectious diseases first endangered human health as the most potentially lethal and debilitating diseases worldwide. The global incidence of infectious diseases has increased significantly over the past decades, such as COVID-19, cholera, dengue, and influenza. Key elements in combating and controlling diseases include monitoring and reporting infectious disease timelines and geographic distribution. We obtained surveillance data from Shusi Tech’s Global Epidemic Information Monitoring System and comprehensively analyzed the timing and location of outbreaks in infected populations from 24 March 2023 to 23 April 2023. Recent worldwide outbreaks of infectious diseases highlight the need to implement effective monitoring strategies and warning systems

Global Infectious Diseases in May 2023: Monthly Analysis

In the past 5 years, there has been a growing focus on infectious diseases, such as viral infections (coronavirus, Mpox, and influenza), sudden pandemics, and persistent bacterial infections (cholera, malaria, and tuberculosis) that continue to be a challenge in epidemic areas. We analyzed epidemic data from dozens of infectious diseases between 24 April and 23 May 2023 using Shusi Tech’s Global Epidemic Information Monitoring System. This analysis will provide a quick overview of the global epidemic status, and will facilitate the prediction and assessment of future pandemics

Global Infectious Diseases in July 2023: Monthly Analysis

Many infectious diseases are ubiquitous and pose persistent adverse effects on public health. Infectious diseases have also been leading causes of high mortality in different periods of history. Real-time monitoring and analysis of global infectious disease transmission can provide a comprehensive understanding of critical information regarding the transmission routes, scope, velocity, and effects of viruses or bacteria. Here, using Shusi Tech’s Global Epidemic Information Monitoring System, we analyzed the prevalence of infectious diseases worldwide. We describe types of infectious diseases with relatively low incidence from 24 June 2023 to 23 July 2023 as comprehensibly as possible
