Funding of curiosity-driven science is the lifeblood of scientific and technological innovation. Various models of funding allocation became institutionalized in the 20th century, shaping the present landscape of research funding. There are numerous reasons for scientists to be dissatisfied with current funding schemes, including the imbalance between funding for curiosity-driven and mission-directed research, regional and country disparities, path-dependency of who gets funded, gender and race disparities, low inter-reviewer reliability, and the trade-off between the effort and time spent on writing or reviewing proposals and doing research.

Article Synopsis
  • CD2, CD25, and CD30 expression in extracutaneous mast cells is a minor diagnostic criterion for systemic mastocytosis (SM), as categorized by the World Health Organization and International Consensus Classification.
  • A study of 5,034 patients revealed that lower percentages of CD2, CD25, and/or CD30 in mast cells are seen in indolent SM compared to advanced forms like aggressive SM and mast cell leukemia.
  • The absence of CD2 in mast cells is linked to significantly lower overall survival and indicates the potential for disease spread outside the bone marrow to organs like the spleen and liver.

Background: Histological findings of infective endocarditis (IEs) in mechanical valves present a complex diagnostic challenge owing to the lack of a precise definition. This ambiguity is further complicated by the natural degenerative processes that occur in the mechanical valves over time. Consequently, pathologists and clinicians face significant difficulties in distinguishing between genuine infective processes and the normal wear and tear of mechanical valves.

Background: Diabetes mellitus is closely related to periodontal disease and dental lesions, disorders which through dental infection and metabolic imbalance become negatively potentiated and cause a vicious circle that is almost impossible to break. The aim of this research was to study if the severity of dental and periodontal lesions is related to the presence of microvascular complications and glycemic control in patients with type 2 diabetes mellitus (T2DM).

Methods: In total, 112 subjects with T2DM that underwent a dental evaluation were enrolled in this case-control study.

In recent decades, it has become clear that the gut is more than just a digestive organ; it also functions as an immune organ with regulatory capabilities and acts as a "second brain" that influences brain function due to the presence and regulatory roles of the gut microbiota (GM). The GM is a crucial component of its host and significantly impacts human health. Dysbiosis, or microbial imbalance, has been closely linked to various diseases, including gastrointestinal, neurological, psychiatric, and metabolic disorders.
