First insight into eosinophils as a biomarker for the early distinction of COVID-19 from influenza A in outpatients.

Coronavirus disease 2019 (COVID-19) and influenza A outbreaks have spread rapidly in China. It is difficult to accurately differentiate these two different respiratory tract infections on the basis of their similar early-stage symptoms and lymphocytopenia. In the present study, the age, sex and white blood cell, neutrophil, lymphocyte, monocyte and eosinophil counts, as well as the neutrophil-to-lymphocyte ratio (NLR) of 201 outpatients with confirmed COVID-19 and 246 outpatients with influenza A were investigated and compared.

Innovative therapeutic strategies for intrauterine adhesions: Role of umbilical cord mesenchymal stem cells in rat models.

Intrauterine adhesions (IUAs) represent a considerable impediment to female reproductive health. Despite ongoing debate regarding the optimally efficacious route of administration and dosage of stem cells for IUA treatment, human umbilical cord-derived mesenchymal stem cells (UCMSCs) have emerged as a promising avenue for regenerative therapy. The present study aimed to investigate the potential effects of UCMSCs on IUAs and to further explore the most effective treatment route and dosages.

Laser localization with soft‑channel minimally invasive surgery in cerebral hemorrhage.

The aim of the present study was to evaluate the efficacy and safety of laser localization combined with soft-channel minimally invasive surgery (MIS) for the treatment of cerebral hemorrhage, and to develop stereotactic alternatives that are cost-effective, safe and precise for underdeveloped regions. To meet this aim, 60 patients with cerebral hemorrhage were randomly assigned to the control group (n=30) or the study group (n=30). The patients in the study group were treated with laser localization combined with soft-channel MIS to remove the hematoma, whereas the control group was treated with YL-1 needle puncture to drain the intracranial hemorrhage.

This therapy would lead to sparing of normal tissue which has been termed the FLASH effect.

Rapid synthesis of manganese dioxide nanoparticles for enhanced biocompatibility and theranostic applications.

Manganese dioxide (MnO), lauded for its biocompatibility and distinctive optical and physical characteristics, has become an indispensable material in the biomedical field, showing immense potential in disease detection, treatment, and prevention. Particularly, the ability of MnO nanoparticles to oxidize glutathione (GSH) to its oxidized form has positioned them as pivotal players in GSH sensing. However, conventional preparation methods, whether top-down or bottom-up, often result in nanoparticles that require multi-step processing and modification to achieve good dispersion in physiological conditions, which is both time-consuming and complex.

A free-radical initiator-based carrier-free smart nanobomb for targeted synergistic therapy of hypoxic breast cancer.

Thermodynamic therapy (TDT) is a promising alternative to photodynamic therapy (PDT) by absorbing heat through thermosensitive agents (TSAs) to generate oxygen-irrelevant highly toxic free radicals. Therefore, TDT can be a perfect partner for photothermal therapy (PTT) to achieve efficient synergistic treatment of anoxic tumors using a single laser, greatly simplifying the treatment process and overcoming hypoxia limitations. However, the issues of how to improve the stability and delivery efficiency of TSAs still need to be addressed urgently.

Proton Beam Therapy for a Rare Anaplastic Pleomorphic Xanthoastrocytoma: Case Report and Literature Review.

Anaplastic pleomorphic xanthoastrocytoma (PXA) is a rare, aggressive WHO grade III tumor that primarily affects children and young adults. Despite surgery being the primary treatment, achieving complete tumor removal is often difficult due to its infiltrative nature, necessitating additional therapies like proton beam therapy (PBT). PBT, known for its precision in targeting tumors while minimizing damage to surrounding healthy tissue, has shown promise in treating malignant gliomas.

Ongoing invasions by American bullfrogs and red-eared sliders in the Republic of Korea.

Invasive species can be unpredictable in their ability to adapt and spread across novel landscapes. American bullfrogs () and red-eared sliders () have become invasive in South Korea since their introduction in the 1970s through the food and pet trades. One of the first steps to their population regulations is to determine each species' distribution in the country, which will allow for the identification of at-risk areas.

Advancing band structure simulations of complex systems of C, Si and SiC: a machine learning driven density functional tight-binding approach.

We present a machine learning (ML) workflow for optimizing electronic band structures using density functional tight binding (DFTB) to replicate the results of costly hybrid functional calculations. The workflow is trained on carbon, silicon, and silicon carbide systems, encompassing bulk, slab, and defect geometries. Our method accurately reproduces hybrid functional results by applying a DFTB-ML scheme to train and predict the scaling parameters of two-center integrals and on-site energies, which is particularly accurate for electronic band structures near the Fermi energy.

Recent studies have shown that ATP at high physiological concentrations (>5 mM) can inhibit liquid-liquid phase separation (LLPS) driven by interactions between intrinsically disordered proteins (IDPs). However, the mechanism underlying such inhibitory effect still remains elusive. Here, we used all-atom molecular dynamics simulation to study the interaction of ATP with two typical IDPs (i.

Probing the structural transformation and bonding of metal-boride clusters MB (M = La, Ta, Re, Ir).

Theoretical investigations using density functional theory (DFT) and wavefunction theory (WFT) have been performed to understand the geometric and electronic structures, chemical bonding, and structural transformation of 5d6s-metal doped triboron clusters MB (M = La, Ta, Re, Ir; = 1, 3, 5, 7). Global-minimum structural searches find that early-metal doped MB (M = La, Ta) clusters adopt a two-dimensional (2D) planar structure, with σ- and π-type delocalized molecular orbitals (MOs) consisting of M-5d and B-2p atomic orbitals (AOs) identified by chemical bonding analysis. In contrast, late-metal doped MB (M = Re, Ir) clusters prefer three-dimensional (3D) structures of near-pyramidal and triangular pyramid geometries, respectively, which exhibit enhanced stability involving σ- and δ-type M(5d)-B(2p) interactions.

Temporal trends of liver cancer burden, comparative analysis of risk factors and trend forecasts to 2024 in China, USA, the Republic of Korea, and Mongolia: an analysis based on multiple data sources from Global Burden of Disease 2019, the Global Cancer Observatory, and Cancer Incidence in Five Continents.

Bulk photovoltaic effect in a two-dimensional ferroelectric semiconductor α-InSe.

The bulk photovoltaic effect, arising from the separation of charge carriers driven by crystal symmetry, is an intriguing physical phenomenon that has been attracting broad interest in the field of photovoltaic applications due to its junction-free nature and potential to surpass the Shockley-Queisser limit. The photovoltaic applications of conventional ferroelectric materials with wide bandgaps (2.7-4 eV) are limited due to their low photocurrent densities and weak photovoltaic response in the visible light region.
