The evolution of the immune system of bees is defined by conservation, expansions, and losses

BMC Biology
Background Insect pollinators, such as bees, provide essential ecosystem services yet face increasing environmental challenges, including pathogens, which can negatively impact host fitness.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Mechanisms of molecular evolution

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Both drift and selection are important for nucleotide substitutions in evolution. The nearly neutral theory was developed to clarify the effects of these processes. In this article, the nearly neutral theory is presented with special reference to the nature of weak selection.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Population genomics and epigenomics of Spirodela polyrhiza provide insights into the evolution of facultative asexuality

Communications Biology
Many plants are facultatively asexual, balancing short-term benefits with long-term costs of asexuality. During range expansion, natural selection likely influences the genetic controls of asexuality in these organisms.

Genetic Mechanism of Non-Targeted-Site Resistance to Diquat in Spirodela polyrhiza

Plants
Understanding non-target-site resistance (NTSR) to herbicides represents a pressing challenge as NTSR is widespread in many weeds. Using giant duckweed (Spirodela polyrhiza) as a model, we systematically investigated genetic and molecular mechanisms of ...

Molecular Evolution of Hepatitis Viruses

Intervirology, 1999
Methods and models for analytical and quantitative researches on the evolution of hepatitis viruses using nucleotide sequences and amino acids of hepatitis viruses are described. Methods for the calculation of evolutionary rates and the construction of molecular evolutionary trees, especially by estimating the number of nucleotide substitutions and the

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
