PACS and SPIRE range spectroscopy of cool, evolved stars [PDF]

open access: yes, 2018
Context: At the end of their lives AGB stars are prolific producers of dust and gas. The details of this mass-loss process are still not understood very well.

Structure‐Guided Engineering of a Promiscuous O‐Methyltransferase for a SAM Regeneration Biocatalysis Platform of Methylated Pharmaceuticals

open access: yesAdvanced Science, EarlyView.
A substrate promiscuous and regioselective O‐methyltransferase, SmOMT, is functionally and structurally characterized. A double mutant, SmOMTE152A/I306A, exhibited enhanced catalytic activity. By coupling this mutant with a mutant halide methyltransferase, AtHMTV140T, for SAM regeneration, a superior artificial fusion enzyme, AtHMTV140T‐L95‐SmOMTE152A ...

Clinical periodontal diagnosis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

F13A1‐Mediated Macrophage Activation Promotes MASH Progression via the PKM2/HIF1A Pathway

open access: yesAdvanced Science, EarlyView.
In fatty liver disease, hepatocytes exposed to palmitate release S1P, which activates calcium signaling in macrophages. Elevated calcium enhances the activity of F13A1, driving PKM2 dimerization. The PKM2 dimers cause Warburg effect, translocate to the nucleus, cooperate with HIF1A, and upregulate IL1B expression, ultimately promoting classical ...

Osmo and hydro priming improvement germination characteristics and enzyme activity of Mountain Rye (Secale montanum) seeds under drought stress [PDF]

open access: yes, 2012
Impacts of various concentrations of polyetylenglycol 6000 (PEG 6000)(0, -9, -11, -13 and -15 bar) and hydro priming on Mountain Rye (secale montanum) germination characteristic and enzyme activity were evaluated under drought stress in the seed ...

PEG-6000 induced precipitation of proteins from cold-acclimated Tenebrio molitor larvae

open access: yesProblems of Cryobiology and Cryomedicine, 2015
Spectra of PEG-6000-precipitated proteins from cold-acclimated and non-acclimated Tenebrio molitor larvae were comparatively studied. The composition of precipitated proteins from cold-acclimated and non-acclimated T. molitor larvae was shown as differed qualitatively.

Microenvironment‐Guided Evolution of ssDNA‐SWCNT Probes for Selective Recognition of Aggressive Prostate Cancer Phenotypes

open access: yesAdvanced Science, EarlyView.
Random ssDNA–SWCNT(single strand DNA‐single walled carbon nanotube) library is functionally screened and evolved using high‐throughput 3D prostate tumor spheroids via iterative positive and negative selection, enabling the identification of NIR‐II fluorescent ssDNA‐SWCNT nanoprobe specific for prostate cancer.
