Estimating the time-varying emission rate of peracetic acid.

The use of peracetic acid (PAA) as a general disinfectant has seen increasing usage in recent years, and although it is a strong irritant, exposure monitoring for PAA may often be difficult due to relatively high costs and the potential for interferences by other co-occurring chemicals such as hydrogen peroxide. These issues with exposure monitoring make modeling a potentially useful tool in exposure assessment of PAA if model parameters can be accurately determined. This study estimates the time-varying mass emission rate of PAA for use in exposure modeling by using the small spill model and examines the effect of various environmental conditions on the PAA evaporation rate, including surface roughness/substrate, general ventilation rate, and local wind speed.

High-resolution imaging of organic and inorganic nanoparticles at nanometre-scale resolution by X-ray ensemble diffraction microscopy.

Coherent diffraction microscopy (CDM) is a robust direct imaging method due to its unique 2D/3D phase retrieval capacity. Nonetheless, its resolution faces limitations due to a diminished signal-to-noise ratio (SNR) in high-frequency regions. Addressing this challenge, X-ray ensemble diffraction microscopy (XEDM) emerges as a viable solution, ensuring an adequate SNR in high-frequency regions and effectively surmounting resolution constraints.

Trabectedin promotes oncolytic virus antitumor efficacy, viral gene expression, and immune effector function in models of bone sarcoma.

We previously reported that the DNA alkylator and transcriptional-blocking chemotherapeutic agent trabectedin enhances oncolytic herpes simplex viroimmunotherapy in human sarcoma xenograft models, though the mechanism remained to be elucidated. Here we report trabectedin disrupts the intrinsic cellular antiviral response which increases viral transcript presence in the human tumor cells. We also extended our synergy findings to syngeneic murine sarcoma models, which are poorly susceptible to virus infection.

The attract-kill inhibition mechanism in Ag/chitosan hydrogel for long-acting control of .

In this study, we developed an innovative eco-friendly antiseptic nanocomposite, specifically a silver nanoparticle (Ag NP)-immobilized chitosan hydrogel (Ag@Cs/Cs gel), synthesized through a cross-linking reaction involving polyvinylpyrrolidone (PVP) and tetraethyl orthosilicate (TEOS). This nanocomposite was designed to combat () infections, particularly in Solanaceae plants. Chitosan of varying molecular weights (50-190 kDa for Cs and 300-375 kDa for Cs) was used to control the swelling efficacy and regulate the release of Ag NPs.

Phosphine-Promoted Synthesis of Naphthoquinones Fused with Cyclopentadienyl Moiety Via Ring Expansion: Synthesis, Reactivity, and Ring Contraction Via [1,5] Sigmatropic Rearrangement.

Phosphine-promoted unprecedented [3 + 2] annulation reactions via ring expansion by using 2-benzylidene-indane-1,3-diones and diynoates for the synthesis of biologically interesting novel naphthoquinones fused with a five-membered ring bearing a phosphorus ylide up to 78% yield are described. Further ring contraction through [1,5] sigmatropic rearrangement to the spiro indan-1,3-diones by CPBA oxidation was revealed and inferred through oxidation, followed by protonation. The relevant structures were confirmed by single-crystal X-ray diffraction.

Spirocyclopropanes and Substituted Furans by Controlling Reactivity of 1,3-Enynoates: γ- and δ-Addition of Phosphines to Conjugate Acceptors.

In the Morita-Baylis-Hillman (MBH) reaction, a nucleophile undergoes β-addition to activated alkenes or alkynes, forming reactive intermediates for subsequent carbon-carbon or carbon-hetero bond formation. By using a π-conjugated acceptor, however, an unprecedented reactivity of 1,3-enynoates and indane-1,3-diones was uncovered in the presence of phosphines. When indan-1,3-diones were used, γ-addition of phosphines to 1,3-enynoates was observed for the first time; moderate to good yields were obtained for 14 substances containing the prominent spirocyclopropane scaffold with 100 % retention of (Z)-alkene.

Plate osteosynthesis of phalanx fractures using wide-awake local anesthesia no tourniquet technique is cost-effective and associated with less postoperative pain.

Background: The wide-awake local anesthesia no tourniquet (WALANT) technique, which is based on the local infiltration of lidocaine and epinephrine, is widely used in hand and wrist surgery. However, few studies have been conducted on the cost-benefit analysis of phalanx fracture surgery using the WALANT technique. This study aimed to investigate the clinical condition, as well as the time spent for anesthesia and operation.

Quantification of the interaction forces between dengue virus and dopamine type-2 receptor using optical tweezers.

Background: Dengue virus (DENV) causes the most significant mosquito-borne viral disease with a wide spectrum of clinical manifestation, including neurological symptoms associated with lethal dengue diseases. Dopamine receptors are expressed in central nervous system, and dopamine antagonists have been reported to exhibit antiviral activity against DENV infection in vivo and in vitro. Although identification of host-cell receptor is critical to understand dengue neuropathogenesis and neurotropism, the involvement of dopamine receptors in DENV infection remains unclear.
