Comparison of Oral Microbiota Collected Using Multiple Methods and Recommendations for New Epidemiologic Studies

open access: yesmSystems, 2020
Epidemiologic studies use various biosample collection methods to study associations between human oral microbiota and health outcomes. However, the agreement between the different methods is unclear.

Materials‐Guided Gene‐Ionizable Lipid Nanoparticles to Reverse Iron‐Associated Immune Resistance in Renal Cancer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Iron overload is a common metabolic disturbance in cancer and contributes to poor outcomes in renal cell carcinoma (RCC), yet its effects on the tumour immune microenvironment remain unclear. Here we identify a previously unrecognized immunosuppressive axis in which iron overload downregulates the palmitoyltransferase ZDHHC12 in CD8+ T cells ...

Comparison of histomorphology and DNA preservation produced by fixatives in the veterinary diagnostic laboratory setting [PDF]

open access: yesPeerJ, 2014
Histopathology is the most useful tool for diagnosis of a number of diseases, especially cancer. To be effective, histopathology requires that tissues be fixed prior to processing.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

open access: yesAdvanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Mix it and fix it: functions of composite olfactory signals in ring-tailed lemurs [PDF]

open access: yesRoyal Society Open Science, 2016
Animals communicating via scent often deposit composite signals that incorporate odorants from multiple sources; however, the function of mixing chemical signals remains understudied.

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

open access: yesAdvanced Science, EarlyView.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.

Fixed points and homotopy fixed points

open access: yesCommentarii Mathematici Helvetici, 1988
Let G be a finite group, EG be a free contractible G-space, and define \(X^{hG}=Map_ G(EG,X)\) (equivariant mapping space). The main theorem of this paper proves that the following two statements are equivalent (Theorem A): (1) G is a p-group. (2) For every finite G-simplicial complex X, the fixed point set \(X^ G=\emptyset\) if and only if \(X^{hG ...

Herba Lysimachiae Polysaccharide‐Modified Selenium Nanoparticles Alleviate Oxidative Injury in Kidney Stones via TOMM22‐Regulated Mitophagy Activation

open access: yesAdvanced Science, EarlyView.
HLP‐SeNPs, a Lysimachia christinae polysaccharide‐modified selenium nanoparticle, treat kidney stones by downregulating TOMM22 expression, which reduces PINK1 translocation into mitochondria and promotes its retention on the outer mitochondrial membrane.

On Characterizations of Fixed and Common Fixed Points

open access: yesJournal of Mathematical Analysis and Applications, 1998
The authors introduce the concept of \(L\)-mapping which is equivalent to the concept of \(C\)-mapping introduced by \textit{S. Zhang} [Proc. Am. Math. Soc. 97, 343-346 (1986; Zbl 0593.54045)] and establish criteria for the existence of fixed points of \(L\)-mappings.

Renal IGFBP6 Interacts With THBS1 to Drive Renal Cellular Senescence and Fibrosis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Epithelial dedifferentiation and myofibroblast activation are critical drivers of chronic kidney disease (CKD) progression. Elevated levels of IGFBP6 have been linked to decreased renal function in CKD patients, but its precise role and underlying mechanisms remain unclear.
