A method for performing capillary microscopy using an ophthalmoscope is described. Using this technic, we examined 130 patients with various connective tissue diseases. As in prior studies, four patterns could be discerned; scleroderma (SD) pattern, lupus erythematosus (LE) pattern, normal pattern, and a nonspecific pattern. Of the patients with systemic SD, 70% had SD pattern. Of LE patients, 53% had LE pattern. There was little crossover. It is hoped that the use of the ophthalmoscope will result in the widespread use of capillary microscopy.

Plasma S100β is a predictor for pathology and cognitive decline in Alzheimer's disease.

Fluids Barriers CNS

Background: Blood-brain barrier dysfunction is one characteristic of Alzheimer's disease (AD) and is recognized as both a cause and consequence of the pathological cascade leading to cognitive decline. The goal of this study was to assess markers for barrier dysfunction in postmortem tissue samples from research participants who were either cognitively normal individuals (CNI) or diagnosed with AD at the time of autopsy and determine to what extent these markers are associated with AD neuropathologic changes (ADNC) and cognitive impairment.

Methods: We used postmortem brain tissue and plasma samples from 19 participants: 9 CNI and 10 AD dementia patients who had come to autopsy from the University of Kentucky AD Research Center (UK-ADRC) community-based cohort; all cases with dementia had confirmed severe ADNC.

Electronic address:

Background: Scanning electrochemical microscopy (SECM) is a kind of scanning probe technology that enables the obtainment of surface morphology and electrochemical information by recording changes in Faraday current triggered by the movement of probe.

Results: In this work, flexible disk ultramicroelectrode (UME) with highly repeatable geometry are fabricated through a simple and universal strategy that involves vacuum pulling the glass capillaries inserted with platinum wire (gold wire, carbon fiber, etc.), followed by a rapidly heated sealing and polishing process.

Combining In Vivo Two-Photon and Laser Speckle Microscopy With the Ex Vivo Capillary-Parenchymal Arteriole Preparation as a Novel Approach to Study Neurovascular Coupling.

Microcirculation

January 2025

Geoffrey Jefferson Brain Research Centre, Manchester Academic Health Science Centre, Northern Care Alliance NHS Foundation Trust, University of Manchester, Manchester, UK.

Objective: Cerebral blood flow (CBF) decline is increasingly recognized as an area of importance for targeting neurodegenerative disorders, yet full understanding of the mechanisms that underlie CBF changes are lacking. Animal models are crucial for expanding our knowledge as methods for studying global CBF and neurovascular coupling in humans are limited and require expensive specialized scanners.

Methods: Use of appropriate animal models can increase our understanding of cerebrovascular function, so we have combined chronic cranial windows with in vivo two-photon and laser speckle microscopy and ex vivo capillary-parenchymal arteriole (CaPA) preparations.

Nano-LC with New Hydrophobic Monolith Based on 9-Antracenylmethyl Methacrylate for Biomolecule Separation.

Int J Mol Sci

December 2024

Department of Chemistry, College of Science, Taif University, Taif P.O. Box 11099, Saudi Arabia.

In this study, new monolithic poly(9-anthracenylmethyl methacrylate-co-trimethylolpropane trimethacrylate (TRIM) columns, referred as ANM monoliths were prepared, for the first time, and were used for the separation media for biomolecules and proteomics analysis by nano-liquid chromatography (nano-LC). Monolithic columns were prepared by in situ polymerization of 9-anthracenylmethyl methacrylate (ANM) and trimethylolpropane trimethacrylate (TRIM) in a fused silica capillary column of 100 µm ID. Polymerization solution was optimized in relation to monomer and porogenic solvent.
