The Study of a Monumental Structure Ruins to the Southwest of the Cathedral Mosque in Bolgar City
Поволжская археология, 2012 The ruins of a large brick building were revealed on the Bolgar city site to the southwest of the Cathedral mosque. The structure was studied during the 1989-1993, 2000 and 2011 excavations. It has been found that that its outer walls were built of baked

The effect of subjective fish scale ageing on growth and recruitment analyses: a case study from the UK [PDF]
Acta Ichthyologica et Piscatoria, 2006 Background. Re-ageing of scales sampled in 1985 from the population of roach, Rutilus rutilus (L.), of the River Stour, England, revealed a high degree of subjectivity in their ageing, resulting from contrasting interpretations of similar scale features ...

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.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

IEEE Transactions on Signal Processing, 1993 The accumulated product of orthogonal matrices gradually departs from orthogonality, due to rounding errors. An attractive remedy for this problem, because of its simplicity, consists in renormalizing the columns (scaling) after each partial product.
