Degenerate Diffusion Operators Arising in Population Biology
, 2011 We analyze a class of partial differential equations that arise as "backwards Kolmogorov operators" in infinite population limits of the Wright-Fisher models in population genetics and in mathematical finance. These are degenerate elliptic operators defined on manifolds with corners. The classical example is the Kimura diffusion operator, which acts on

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Isolation and Characterization of Novel Insertional Mutants in the Early Region 1A of Adenovirus Type 5 [PDF]
, 1989 The early region 1A (E1A) of adenovirus 5 codes for oncoproteins whose functions are central to the life cycle of the virus. Its involvement in the initiation of the oncogenic transformation process has been a subject of intense study to understand the ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

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.

Concrete and Formal Operational Thought: Implications for Introductory College Biology [PDF]
The American Biology Teacher, 1976 THE COGNITIVE ABILITIES of concrete operational and formal operational thinkers, as defined by the Swiss psychologist Jean Piaget, have received a great deal of attention in recent years. This article briefly describes the stages involved in Piaget's model and reviews the current literature as it applies to Piaget's ideas and specifically to students ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
