Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Classically projective groups and pseudo classically closed fields
, 2007 Introduction Let K be a PAC (pseudo algebraically closed) field. Then the absolute Galois group GK of K is projective by Ax [A], i.e., group extensions of GK by a finite groups H \Gamma! GK ! 1 are split: There exists oe : GK ! F such that oe = id GK

The equivariant cohomology of weighted projective spaces [PDF]
, 2007 We describe the integral equivariant cohomology of a weighted projective space in terms of piecewise polynomials, as well as by generators and relations.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Evaluating Public Policy Formation and Support Mechanisms for Technological Innovation
Policy evaluation is a complex task. Most approaches now adopt a mixed method approach combining both quantitative and qualitative techniques. A shortcoming of the standard approaches is that they fail to measure or investigate deeper perceptions of the ...

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment
Aging and Cancer, EarlyView.Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Einstein metrics in projective geometry
, 2015 It is well known that pseudo-Riemannian metrics in the projective class of a given torsion free affine connection can be obtained from (and are equivalent to) the solutions of a certain overdetermined projectively invariant differential equation.

Long‐Term Follow‐Up of Chemotherapy‐Associated Biological Aging in Women With Early Breast Cancer
Aging and Cancer, EarlyView.Women threated with adjuvant chemotherapy for early breast cancer have sustained long‐term increase in p16INK4a,, a robust marker of cell senescence, suggesting a chemotherapy‐associated age acceleration. p16INK4a as well as other biomarkers may identify patients at greatest risk for senescence‐related diseases of aging.
