SPECIES: An R Package for Species Richness Estimation

Journal of Statistical Software, 2011
We introduce an R package SPECIES for species richness or diversity estimation. This package provides simple R functions to compute point and confidence interval estimates of species number from a few nonparametric and semi-parametric methods.

RUNX2 Activation in Fibro/Adipogenic Progenitors Promotes Muscle Fibrosis in Muscular Dystrophy

Advanced Science, EarlyView.
This study revealed a novel role of the chemokine‐TGF‐β1‐RUNX2 axis in determining the fate of FAP differentiation and modulating muscle fibrosis in patients and mice with muscular dystrophies. ABSTRACT Clinical evidence indicates concurrent muscle inflammation and fibrosis in muscular dystrophies (MDs); however, the molecular mechanisms underlying ...

Nonparametric Estimation of the Tail-Dependence Coefficient

Revstat Statistical Journal, 2013
A common measure of tail dependence is the so-called tail-dependence coefficient. We present a nonparametric estimator of the tail-dependence coefficient and prove its strong consistency and asymptotic normality in the case of known marginal ...

Diffusion‐MRI‐Based Estimation of Cortical Architecture via Machine Learning (DECAM) in Primate Brains

Advanced Science, EarlyView.
We present Diffusion‐MRI‐based Estimation of Cortical Architecture via Machine Learning (DECAM), a deep‐learning framework for estimating primate brain cortical architecture optimized with best response constraint and cortical label vectors. Trained using macaque brain high‐resolution multi‐shell dMRI and histology data, DECAM generates high‐fidelity ...

Nonparametric variance estimation

, 2022
Im heteroskedastischen nichtparametrischen Regressionsmodell mit unbekanntem Erwartungswert f und Varianz V werden Probleme bezueglich der Varianz V untersucht. Im ersten Teil dieser Dissertation wird davon ausgegangen, dass die Varianz V Hoelder-stetig ist. Eine obere Schranke fuer das gleichmaessige Risiko mit einem linearen Schaetzer wird abgeleitet,

The KDM6B/SLC10A2 Axis Suppresses MDSCs Recruitment via ERK/AP‐1 Signaling in Colorectal Cancer

Advanced Science, EarlyView.
In wild‐type intestinal epithelial cells, KDM6B demethylates SLC10A2 to promote its expression, after which SLC10A2 suppresses ERK phosphorylation, inhibiting AP‐1 (Fos/Jun) transcription and chemokine production. In KDM6B‐deficient intestinal epithelial cells, SLC10A2 methylation increases, and its expression decreases.

OPTRACE: Optical Imaging–Guided Transplantation and Tracking of Cells in the Mouse Brain

Advanced Science, EarlyView.
OPTRACE establishes an optical, two‐step platform for intracerebral cell therapy. Transparent glass pipettes enable real‐time, image‐guided delivery, while multiplex genetic labeling with two‐photon and bioluminescence readouts supports longitudinal single‐cell tracking and host–graft dynamics.

Jackknife Estimator of Species Richness with S-PLUS

Journal of Statistical Software, 2005
An estimate of the number of species, S , usually called species richness by ecologists, in an area is one of the basic statistics used to ascertain biological diversity. Traditionally ecologists have used the number of species observed in a sample, S0 ,

OCIAD2 Stabilizes Integrin β1 Signaling Through SNX17‐Mediated Endosomal Recycling to Lipid Rafts and Modulates Cisplatin Response in HNSCC

Advanced Science, EarlyView.
This study identifies OCIAD2 as a critical regulator of cisplatin resistance in HNSCC. Mechanistically, OCIAD2 stabilizes integrin β1 through a direct physical interaction and facilitates its SNX17‐dependent endosomal recycling to lipid raft microdomains. Targeting OCIAD2 disrupts integrin β1 trafficking and significantly enhances cisplatin sensitivity,
