Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Journal of Combinatorial Theory, Series A, 1999 \textit{T. Penttila} and \textit{B. Williams} [Geom. Dedicata, to appear] have constructed a sporadic translation ovoid of the quadrangle \(Q(4, 3^5)\). Associated with this, there is a new (semifield) flock of a quadratic cone in \(\text{PG}(3,3^5)\), and hence a flock generalized quadrangle of order \((3^5,3^{10})\).

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.

Discrete Mathematics, 2002 This interesting article deals with flocks of the quadratic cone \(K\) of \(PG(3, q)\) with equation \(x_0x_1 = x_2^2\) and vertex \(v = (0,0,0,1)\). A flock \(F\) of \(K\) is a partition of \(K \setminus \{v\}\) into \(q\) conics. Note that for every flock \(F = \{\pi_t\}\) there exist two maps \(f\) and \(g\) of \(GF(q)\) such that \(\pi_t\) has the ...

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.

Some causes of the variable shape of flocks of birds.
PLoS ONE, 2011 Flocks of birds are highly variable in shape in all contexts (while travelling, avoiding predation, wheeling above the roost). Particularly amazing in this respect are the aerial displays of huge flocks of starlings (Sturnus vulgaris) above the sleeping ...

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.

Investigation of a Simple Model for Within-Flock Transmission of Scrapie. [PDF]
PLoS ONE, 2015 Genetic control programs for scrapie in sheep build on solid knowledge of how susceptibility to scrapie is modulated by the prion protein genotype at the level of an individual sheep. In order to satisfactorily analyze the effectivity of control programs
