Aims: Diabetes mellitus (DM) induces increased inflammation of atherosclerotic plaques, resulting in elevated plaque instability. Mesenchymal stem cell (MSC) therapy was shown to decrease plaque size and increase stability in non-DM animal models. We now studied the effect of MSC therapy in a streptozotocin-induced hyperglycaemia mouse model using a clinically relevant dose of adipose tissue-derived MSCs (ASCs).

Background And Objectives: Structural and functional changes in the intramyocardial microcirculation increase the risk of myocardial infarction (MI). This study investigated intramyocardial perivascular fibrosis and pro-fibrotic cellular transitions in deceased acute and subacute MI patients to explore their involvement in the pathogenesis of MI.

Methods: Left ventricular tissue (LV) was obtained from the infarction area of autopsied patients with acute-phase MI (3-6 h;  = 24), subacute-phase MI (5-14 days;  = 12), and noninfarcted controls ( = 14).

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Introduction: Telemedicine is a health service that provides diagnosis, treatment evaluation, preventive medicine by using information and communication technologies between distant locations and aims to improve the health of the individuals and society. Social restrictions were applied during the pandemic process caused by coronavirus disease-2019 due to the virus called severe acute respiratory syndrome coronavirus-2 which emerged in late 2019. Through remote communication and information technologies in the followup of asthma patients, there is a need for studies on the effectiveness of using telemedicine methods was seen.

Purpose: This study aims to present a case involving intermittent bleeding from the iridocorneal angle following gonioscopy-assisted transluminal trabeculotomy (GATT) surgery, followed by the development of ghost cell glaucoma (GCG).

Methods: A 25-year-old man with a history of post-traumatic angle recession glaucoma underwent uneventful 360° GATT surgery.

Results: Two weeks after the surgery, while the reason for the incomplete resolution of hyphema remained unclear, intermittent bleeding from the iridocorneal angle and hemorrhage in the inferior vitreous were observed during the patient's follow-up examination.

This research explores the extraction of ferulated arabinoxylans (FAXs) from maize bran and their incorporation into wheat flour to assess their impact on rheological and pasting properties. Flour blends were prepared with FAX concentrations of 0%, 2%, 4%, 6%, 8%, and 10%, and these blends were then evaluated using farinograph, mixograph, micro-extensibility, and viscosity analyses. The results indicated that farinograph water absorption increased significantly ( ≤ 0.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.

Article Synopsis
  • - The ATLAS experiment at the LHC conducted a search for long-lived particles (LLPs) using a large dataset (140 fb^{-1}) from proton-proton collisions at 13 TeV, focusing on LLPs with masses from 5 to 55 GeV that decay within the inner detector.
  • - The study considered scenarios where LLPs are produced from exotic Higgs boson decays and models involving axionlike particles (ALPs).
  • - No significant findings above expected background levels were detected, leading to the establishment of upper limits on various production rates involving the Higgs boson and the top quark related to LLPs and ALPs.

Article Synopsis
  • The study investigates the associated production of Higgs and W bosons, focusing on how the relative signs of the Higgs couplings to W and Z bosons impact the process.
  • Two specific searches were conducted using large amounts of collision data from the LHC to analyze different coupling scenarios: one for opposite-sign couplings and another for same-sign (standard model-like) couplings.
  • The results significantly exclude the opposite-sign coupling hypothesis and set a strict upper limit on the production rate of this process compared to standard model predictions.

This research investigates the influence of milling methods and starter cultures on the structural characteristics of water-extractable arabinoxylans (WE-AX) in stone-milled whole-grain flour and sourdough bread. Stone milling was conducted to generate six different whole wheat flour samples, from which sourdough bread was produced using wheat and rye starter cultures. The study found that both milling parameters and the type of starter culture significantly impacted the fine structural details of WE-AX, including sugar composition, arabinoxylan (AX) content, and the arabinose-to-xylose (A/X) ratio values.
