Aging Cell, EarlyView.Explants of human postmenopausal ovarian cortex and medulla were treated with doxorubicin for 24 h followed by culture for up to 10 days in doxorubicin‐free medium. Single nuclei sequencing and proteomics revealed an unbiased signature of ovarian senescence driven by epithelial cells in the cortex and stromal cells in the cortex and medulla ...

The FEBS Journal, EarlyView.We show that Mub1 links cell wall robustness with the ubiquitin‐proteasome system. As an adaptor protein of the E3 ubiquitin ligase Ubr2, it facilitates the ubiquitination of various transcription factors, including Mcm1 and Swi4. Yeasts evolved a complex regulatory programme to build and maintain their cell wall, the primary structure through which ...

The FEBS Journal, EarlyView.In healthy neurons, Protein kinase A (PKA) forms a tetrameric holoenzyme enabling precise allosteric regulation. We characterized a novel neurodegenerative disease, neuronal loss, and parkinsonism driven by PRKAR1B mutation (NLPD‐PKA), demonstrating disrupted holoenzyme assembly, reduced cooperativity, and increased catalytic subunit nuclear ...

Some transformations of basic hypergeometric series and their applications [PDF]
Proceedings of the American Mathematical Society, 1980 Using Bailey’s transformation, relations between basic and basic bilateral hypergeometric series are obtained. Some interesting special cases, like identities of Rogers-Ramanujan type, summation theorems for particular basic bilateral hypergeometric series 2 ψ 2

A short proof of an identity of Sylvester
International Journal of Mathematics and Mathematical Sciences, 1999 We present two short proofs of an identity found by Sylvester and rediscovered by Louck. The first proof is an elementary version of Knuth's proof and is analogous to Macdonald's proof of a related identity of Milne.

Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?
Journal of Financial Research, EarlyView.Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...

Generalizations of Ramanujan's reciprocity formula and the Askey-Wilson integral [PDF]
, 2013 By using two known transformation formulas for basic hypergeometric series, we establish a direct extension of Bailey's $_6\psi_6$-series identity. Subsequently, it and Milne's identity are employed to drive multi-variable generalizations of Ramanujan's ...

The Modern Language Journal, EarlyView.Abstract Lexical proficiency in a second language (L2) has long been effectively assessed through the measurement of various lexical indices, or textual characteristics that act as observable indicators of such conceptual categories as lexical richness, diversity, sophistication, and fluency.
