Controlled Engineering of 2D Alkali‐Iron‐Chloride Compounds and Lateral Quantum Heterostructures Within Confined Graphene Nanoreactors

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a programmable atomic engineering strategy for 2D materials using Å‐scale nanoreactors formed by bilayer graphene (BLG) intercalation. A new class of alkali‐iron‐chloride compounds, along with lateral heterostructures composed of monolayer alkali halides and iron chlorides, is revealed.

Simultaneous Electrochemical Detection of NGF and proNGF Under Native Conditions Using Molecularly Imprinted Polymers: Toward Point‐of‐Care Diagnosis of Alzheimer's Disease

open access: yesAdvanced Healthcare Materials, EarlyView.
This study relies on the development of a new sensor that can detect two closely related proteins involved in Alzheimer's disease at the same time. Unlike traditional methods, it works in natural conditions and does not require sample pretreatment. The device is highly sensitive and was successfully tested on patient samples, offering promises for ...

Diachronic changes the Nicaraguan sign language classifier system: Semantic and phonological factors

open access: yesOpen Linguistics
This article presents an exploration of the usage and distribution of the 1-handshape classifier (Cl-1) and the 2-handshape classifier (Cl-2), both diachronically and synchronically, tracking classifier development in a detailed dataset of Nicaraguan ...

Arterial spin labeling image findings in the acute phase in paediatric patients with acute encephalopathy with biphasic seizures and late reduced diffusion

open access: yesFrontiers in Neuroscience, 2023
IntroductionDiagnosing acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) after the first seizure (early seizure/seizures, ES/ESs) is challenging because a reduced apparent diffusion coefficient (ADC) in the cortical or ...

Ammonia Detoxification Inhibits Liver Metastasis by Reshaping Hepatic Microenvironment

open access: yesAdvanced Science, EarlyView.
Liver metastasis diverts aspartate into hyperactive pyrimidine synthesis, disrupting urea cycling and causing pathogenic ammonia accumulation. Ammonia dually reprograms the microenvironment by: (1) activating hepatic stellate cells (HSCs) into pro‐fibrotic metastasis‐associated fibroblasts (MAFs), and (2) suppressing anti‐tumor monocytes/macrophages ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

A nationwide assessment of hepatocellular adenoma resection: Indications and pathological discordance

open access: yesHepatology Communications, EarlyView., 2022
Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.

The possibilities of the non-contrast MRI perfusion in the quantitative assessment of changes in cerebral blood flow

open access: yesСибирский научный медицинский журнал
Arterial spin labeling (ASL) allows the assessment of tissue perfusion and has advantages such as non-invasiveness and the ability to repeat examinations multiple times. This enables dynamic monitoring without contrast administration.

Atherosclerotic risk is associated with cerebral perfusion – A cross-sectional study using arterial spin labeling MRI

open access: yesNeuroImage: Clinical, 2022
Background: Arterial spin labeling (ASL) magnetic resonance imaging (MRI) may be a promising technique to evaluate the presence of cerebral atherosclerosis.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...
