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 ...

Decay $B_c^{+}\to D_{\left(s\right)}^{(*)+}{\ell }^{+}{\ell }^{-}$ within covariant confined quark model

Physical Review
We study the rare semileptonic decays of Bc mesons within the effective field theoretical framework of covariant confined quark model. The transition form factors corresponding to Bc+→D(*)+ and Bc+→Ds(*)+ are computed in the entire q2 range. Using form factors, we compute the branching fractions and compare them with the available theoretical results ...

Study of $B_s\to K^{(*)}{\ell }^{+}{\ell }^{-}$ decays in the PQCD factorization approach with lattice QCD input

Physical Review, 2020
In this paper, we studied systematically the semileptonic decays B¯s→K(*)ℓ+ℓ− with l−=(e−,μ−,τ−) by using the perturbative QCD (PQCD) and the “PQCD+Lattice” factorization approach, respectively. We first evaluated all relevant form factors Fi(q2) in the low-q2 region using the PQCD approach, and we also took the available lattice QCD results at the end

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.

Angular analysis of $B_s\to f_2^{\prime }\left(1525\right)(\to K^{+}{K}^{-}){\mu }^{+}{\mu }^{-}$ decays as a probe to lepton flavor universality violation

Physical Review, 2021
The flavor anomalies reported in RK, RK*, P5′, and B(Bs→ϕμ+μ−) indicate lepton flavor universality violation in b→sl+l− quark level transition decays. The deviation from the standard model prediction reported in the underlying flavor observables currently stands at the level of 2.5σ, 2.4σ, 3.3σ, and 3.7σ, respectively.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Changes in the germinability and vigour of winter triticale seeds with sprouting damage

Plant, Soil and Environment, 2003
Changes in the germinability and vigour of seeds with sprouting damage obtained after induced sprouting under laboratory conditions were investigated in winter triticale cultivars: Bogo,Moreno, Vero, in the years 1998-2000. The seeds were tested directly

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.
