Introduction: Immunosenescence is a dynamic process, where both genetic and environmental factors account for the substantial inter-individual variability. This paper integrates all the data on immunosenescence markers generated in our laboratory and describes the differences and/or similarities between individuals based on their biological conditions (immunosenescence markers) and their associations with chronological age and health status.

Materials And Methods: The dataset consisted of immunological data from healthy donors, centenarians, patients diagnosed with chronic kidney disease, COVID-19 and non-small cell lung cancer (NSCLC), treatment-naïve or treated with platinum-based chemotherapy.

Citizen science projects optimise the democratisation of the production of scientific knowledge. In these initiatives, research processes do not rely solely on scientists' but on citizens' engagement, likewise with benefits on both sides. As previous work shows, the inclusivity perspective of citizen science projects might be viewed critically as some groups of citizens tend to be overrepresented in these initiatives while others are left out.

Article Synopsis
  • The study aimed to assess oral health changes among university students and their connection to various forms of tobacco use, including e-cigarettes.
  • Out of 620 participants, 57.1% used tobacco, with e-cigarette use being the most common (47.4%), leading to higher rates of oral issues like caries and gingivitis among users.
  • The findings suggest that alternative tobacco forms, like e-cigarettes, may negatively impact oral health, especially when used with other tobacco products, indicating a need for dental awareness and education regarding these risks.

Article Synopsis
  • Scientists are studying how to make more medicines, like vaccines and antibodies, by using special DNA sequences called iPLUS that help produce more proteins.
  • By using iPLUS, they found that they could double the amount of an important cancer treatment protein called trastuzumab in cells and boost other proteins over 100 times in yeast.
  • This research shows that iPLUS could be really useful in making vaccines and other medicines faster and cheaper by improving how genes work in cell production.

The enzyme NADPH-cytochrome P450 reductase (CPR) plays a central role in cytochromes P450 activity. Gene expression analysis of cytochromes P450 and CPR in deltamethrin-resistant and susceptible populations revealed that P450s genes are involved in the development of insecticide resistance in Triatoma infestans. To clarify the role of cytochromes P450 in insecticide resistance, it was proposed to investigate the effect of CPR gene silencing by RNA interference (RNAi) in a pyrethroid resistant population of T.

Population exposure to heat waves (HWs) is increasing worldwide due to climate change, significantly affecting society, including public health. Despite its significant vulnerabilities and limited adaptation resources to rising temperatures, South America, particularly Brazil, lacks research on the health impacts of temperature extremes, especially on the role played by socioeconomic factors in the risk of heat-related illness. Here, we present a comprehensive analysis of the effects of HWs on mortality rates in the 14 most populous urban areas, comprising approximately 35% of the country's population.

  • Sacubitril-valsartan has been shown to lower hospitalizations and death rates in heart failure patients, but there is limited real-world data on its effectiveness in older patients.
  • A study was conducted using a Spanish heart failure registry to compare elderly patients treated with sacubitril-valsartan versus those on angiotensin converting enzyme inhibitors (ACEI) during acute heart failure hospitalization.
  • Results indicated that while sacubitril-valsartan was associated with a trend towards fewer readmissions and deaths due to heart failure compared to ACEI, these findings were not statistically significant over follow-up periods of 3 months and 1 year.

Technology based on artificial small RNAs, including artificial microRNAs (amiRNAs), exploits natural RNA silencing mechanisms to achieve silencing of endogenous genes or pathogens. This technology has been successfully employed to generate resistance against different eukaryotic viruses. However, information about viral RNA molecules effectively targeted by these small RNAs is rather conflicting, and factors contributing to the selection of virus mutants escaping the antiviral activity of virus-specific small RNAs have not been studied in detail.

Cancer patients (CPs) have been identified as particularly vulnerable to SARS-CoV-2 infection, and therefore are a priority group for receiving COVID-19 vaccination. From the patients with advanced solid tumors, about 20% respond very efficiently to immunotherapy with anti-PD1/PD-L1 antibodies and achieve long lasting cancer responses. It is unclear whether an efficient cancer-specific immune response may also correlate with an efficient response upon COVID-19 vaccination.

Alternative polyadenylation in the 3' UTR (3' UTR-APA) is a mode of gene expression regulation, fundamental for mRNA stability, translation and localization. In the immune system, it was shown that upon T cell activation, there is an increase in the relative expression of mRNA isoforms with short 3' UTRs resulting from 3' UTR-APA. However, the functional significance of 3' UTR-APA remains largely unknown.

Cassava brown streak disease (CBSD), dubbed the "Ebola of plants", is a serious threat to food security in Africa caused by two viruses of the family Potyviridae: cassava brown streak virus (CBSV) and Ugandan (U)CBSV. Intriguingly, U/CBSV, along with another member of this family and one secoviridae, are the only known RNA viruses encoding a protein of the Maf/ham1-like family, a group of widespread pyrophosphatase of non-canonical nucleotides (ITPase) expressed by all living organisms. Despite the socio-economic impact of CDSD, the relevance and role of this atypical viral factor has not been yet established.
