Photolithography-Induced Doping and Interface Modulation for High-Performance Monolayer WSe P-Type Transistors.

To mitigate Fermi-level pinning (FLP) at the contact of two-dimensional (2D) transition metal dichalcogenides and enhance their hole carrier concentration, a 1.8 nm-thick p-doping layer is formed via photolithography. This surface treatment significantly reduces the contact resistance () to ∼4.

The application of aptamers in the repair of bone, nerve, and vascular tissues.

Aptamers represent a distinct category of short nucleotide sequences or peptide molecules characterized by their ability to bind to specific targets with high precision. These molecules are predominantly synthesized through SELEX (Systematic Evolution of Ligands by Exponential Enrichment) technology. Recent findings indicate that aptamers may have significant applications in regenerative medicine, particularly in the domain of tissue repair.

Flavopereirine exerts anti-cancer activities in various human thyroid cancer cells.

Thyroid cancer (TC) stands out as the most prevalent endocrine malignancy globally, with a steadily increasing incidence. Its clinical manifestations include enlarged thyroid nodules, dysphagia, enophthalmos, and various other symptoms. While standard treatments such as thyroidectomy and radioiodine therapy effectively manage most cases of differentiated thyroid cancers (DTC), some recurrent cases of DTC or those involving poorly differentiated thyroid cancers (PDTC) require specialized interventions.

Antimony-Platinum Modulated Contact Enabling Majority Carrier Polarity Selection on a Monolayer Tungsten Diselenide Channel.

We develop a novel metal contact approach using an antimony (Sb)-platinum (Pt) bilayer to mitigate Fermi-level pinning in 2D transition metal dichalcogenide channels. This strategy allows for control over the transport polarity in monolayer WSe devices. By adjustment of the Sb interfacial layer thickness from 10 to 30 nm, the effective work function of the contact/WSe interface can be tuned from 4.

This study enrolled 156 head and neck cancer patients and analyzed 342 lymph nodes segmented from surgical pathologic reports.

Cyclizine induces cytotoxicity and apoptosis in macrophages through the extrinsic and intrinsic apoptotic pathways.

Cyclizine, an over-the-counter and prescription antihistamine, finds widespread application in the prevention and treatment of motion sickness, encompassing symptoms such as nausea, vomiting, dizziness, along with its effectiveness in managing vertigo. However, the overuse or misuse of cyclizine may lead to hallucinations, confusion, tachycardia, and hypertension. The molecular mechanisms underlying cyclizine-induced cytotoxicity and apoptosis remain unclear.

Outcome of Thromboembolic Events and Its Influence on Survival Time of Advanced NSCLC Patients Treated with Antiangiogenic Therapy.

Background: Antiangiogenetic therapy and lung cancer, per se, are associated with an increased risk of thromboembolic events (TE). We aim to evaluate the pattern and outcome of TE as well as its influence on survival time of advanced non-small cell lung cancer (NSCLC) patients receiving antiangiogenic therapy.

Methods: This was a retrospective cohort study, which included advanced NSCLC patients receiving antiangiogenic therapy.

Reactivation of Hepatitis B Virus in Lung Cancer Patients Receiving Tyrosine Kinase Inhibitor Treatment.

(1) Background: We aimed to evaluate the risk of hepatitis B virus (HBV) reactivation in lung cancer patients treated with tyrosine kinase inhibitor (TKI), particularly in those with resolved HBV infection. (2) Methods: In this retrospective hospital-based cohort study, we screened all lung cancer patients with positive hepatitis B core antibodies (anti-HBc) receiving systemic antineoplastic treatment during the period from January 2011 to December 2020. Cumulative incidences of HBV reactivation, and their hazard ratios (HRs), were evaluated after adjusting patient mortality as a competing risk.

Influence of the Components and Orientation of Hydroxyapatite Fibrous Substrates on Osteoblast Behavior.

Synthetic hydroxyapatite has good biocompatibility, bioactivity and osteoconductive ability because its chemical properties and biological properties are similar to those of bioapatite in bone tissue. Strontium-substituted hydroxyapatite has better degradability than hydroxyapatite and can both promote osteogenesis and inhibit adipogenesis in mesenchymal stem cells. Hence, hydroxyapatite and strontium-substituted hydroxyapatite are widely used as bone graft materials, cell carriers and drug/gene delivery carriers.

The Effect of Strontium-Substituted Hydroxyapatite Nanofibrous Matrix on Osteoblast Proliferation and Differentiation.

Natural bone tissue consists primarily of bioapatite and collagen. Synthetic hydroxyapatite (HA) possesses good biocompatibility, bioactivity, and osteoconductivity due to its chemical and biological similarity to bioapatite. Hence, HA has been widely used as a bone graft, cell carrier and drug/gene delivery carrier.

Enhanced Sensing Ability of Brush-Like FeO-ZnO Nanostructures towards NO Gas via Manipulating Material Synergistic Effect.

Brush-like α-FeO-ZnO heterostructures were synthesized through a sputtering ZnO seed-assisted hydrothermal growth method. The resulting heterostructures consisted of α-FeO rod templates and ZnO branched crystals with an average diameter of approximately 12 nm and length of 25 nm. The gas-sensing results demonstrated that the α-FeO-ZnO heterostructure-based sensor exhibited excellent sensitivity, selectivity, and stability toward low-concentration NO gas at an optimal temperature of 300 °C.

Case history on Epstein-Barr Virus-associated smooth muscle tumor (EBV-SMT) of cranio-cervical junction in an immunocompetent patient.

Indicators of rapid cognitive decline in amnestic mild cognitive impairment: The role of plasma biomarkers using magnetically labeled immunoassays.

Plasma levels of biomarkers change with the progression of Alzheimer's disease (AD), which involves the accumulation of pathological amyloid β (Aβ) and Tau protein tangles. However, few studies have investigated the association between plasma biomarkers and rapid cognitive decline in patients with amnestic mild cognitive impairment (aMCI) and AD. A total of 10 healthy controls, 24 patients with aMCI, and 19 patients with AD were enrolled.

Collagen Scaffolds Containing Hydroxyapatite-CaO Fiber Fragments for Bone Tissue Engineering.

Collagen (COL) and hydroxyapatite (HAp) are the major components of bone, therefore, COL-HAp composites have been widely used as bone substitutes to promote bone regeneration.
