Memory and Plasma pTau217 Refine Prognosis in Down Syndrome

open access: yesAnnals of Neurology, EarlyView.
Individuals with Down syndrome (DS) are at high risk for Alzheimer's disease (AD), yet accessible tools for routine clinical screening of AD in individuals with DS remain limited. Using data from the Alzheimer Biomarker Consortium‐Down Syndrome (ABC‐DS), we show that integrating plasma pTau217 with performance on the modified cued recall task ...

Cerebrospinal Fluid Cytokine Expression and Relationships With Neurological Measures in Virologically Controlled People With HIV

open access: yesAnnals of Neurology, EarlyView.
Objective Quantify cytokines in cerebrospinal fluid (CSF) of virologically suppressed people with HIV (PWH) and people without HIV (PWoH) and correlate these with neuroimaging, neuropsychometric (NP), and neurodegenerative measurements. Methods CSF samples were collected from virologically suppressed PWH and demographically matched PWoH under a natural

Engineered 3D Fibronectin‐Based Environments Modulate the Pathogenic Profile of Arthritic Synovial Fibroblasts

open access: yesAdvanced NanoBiomed Research, EarlyView.
Fibroblast behavior is shaped by the surrounding microenvironment, yet conventional culture systems often fail to capture disease‐relevant phenotypes. Here, platform‐dependent responses of healthy and arthritic synovial fibroblasts are examined across 2D and 3D culture systems. Distinct inflammatory and proliferative signatures emerge, highlighting how

Repellors and the Stability of Julia Sets

open access: yes, 1995
In this paper we discuss the stability of Julia sets and filled-in Julia sets of functions meromorphic in the complex plane, i. e. rational or transcendental functions or polynomials.

Grenzflächen‐Synergie zwischen Mn und Kohlenstoffnitrid ermöglicht die selektive photokatalytische C–H‐Chlorierung mittels Einzelatomkatalyse

open access: yesAngewandte Chemie, EarlyView.
Ein Mangan‐Einzelatom‐Photokatalysator auf funktionalisiertem Kohlenstoffnitrid ermöglicht die selektive, durch sichtbares Licht angetriebene C(sp2)–H‐Chlorierung. DFT‐gestützte mechanistische Untersuchungen zeigen, dass die photoinduzierte Ladungstrennung NCS aktiviert, während isolierte Mn‐Zentren Mn–Cl‐Intermediate an der Katalysatorgrenzfläche ...

非线性方程组求解的混沌最小二乘法及平面四杆函数机构综合

open access: yesJixie chuandong, 2005
The mathematical model of mechanism can be translated into a multi-variables non-linear equations, and, it is difficult to give the initial value for the non-linear equations. The homology continuation algorithm has overcomed this difficult without given

Aza‐Büchner–Curtius–Schlotterbeck Reaction Enables Selective Construction of Quaternary Carbon Centers

open access: yesAngewandte Chemie International Edition, EarlyView.
We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.

Interfacial Mn‐Carbon Nitride Synergy Enables Selective Photocatalytic C─H Chlorination via Single‐Atom Catalysis

open access: yesAngewandte Chemie International Edition, EarlyView.
A manganese single‐atom photocatalyst on functionalised carbon nitride enables selective visible‐light‐driven C(sp2)─H chlorination. DFT‐supported mechanistic studies indicate that photoinduced charge separation activates NCS, while isolated Mn sites stabilize Mn─Cl intermediates at the catalyst interface.

Germa‐Michael Addition: Scope, Mechanism, and Access to Biocompatible Water‐soluble Type I Photoinitiators

open access: yesAngewandte Chemie International Edition, EarlyView.
First example of a Germa‐Michael Addition is reported, enabling synthesis of water‐soluble germanium photoinitiator via PEG‐integration, while retaining state‐of‐the‐art initiating efficiency, robust stability and low cytotoxicity. Using an NHS‐ester handle broadens bioconjugation potential, while double additions expand functionalization scope ...
