Alpinia calcarata: potential source for the fabrication of bioactive silver nanoparticles

Nano Convergence, 2018
In the present study silver nanoparticles fabricated by using leaf extract of Alpinia calcarata. We have also studied the effect of various experimental parameters viz., metal ion concentration, pH and incubation period on nanoparticle biosynthesis ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Interest Convergence, Intersectionality, and Counter-Storytelling: Critical Race Theory as Practice in Scholarly Communications Librarianship

In the Library with the Lead Pipe
Despite diversity, equity, and inclusion (DEI) rhetoric in librarianship, library workers who are Black, Indigenous, and people of color (BIPOC) are still underrepresented and marginalized.

Effect of ribbon width on electrical transport properties of graphene nanoribbons

Nano Convergence, 2018
There has been growing interest in developing nanoelectronic devices based on graphene because of its superior electrical properties. In particular, patterning graphene into a nanoribbon can open a bandgap that can be tuned by changing the ribbon width ...

Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10

FEBS Open Bio, EarlyView.
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...

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.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

\Sigma-convergence

Banach Journal of Mathematical Analysis, 2011
The usual approach to the weak convergence of a product of functions is to require one of the sequences to converge strongly. For example, if \(u_n \to u\) in \(L^p(\Omega)\), \(v_n \rightharpoonup v\) in \(L^{p^{\prime}}(\Omega)\), then \(u_n v_n \rightharpoonup uv\) in \(L^1(\Omega)\), where \(\rightharpoonup\) means weak convergence.
