Light-responsive antibacterial dissolving microneedles loaded with 5-aminolevulinic acid and silver nanoparticles for the treatment of acne.

Acne is a chronic inflammatory disease of pilosebaceous unit, which can be aggravated by hyperkeratosis of the pilosebaceous unit, excessive secretion of sebum and the proliferation of Propionibacterium acnes (P. acnes). Traditional drug treatment methods commonly exhibit drawbacks, including bacterial resistance and poor transdermal permeability, resulting in suboptimal efficacy and recurrent infections.

Patient with suspected co-infection of hemorrhagic fever with renal syndrome and malaria: a case report.

Background: Hemorrhagic fever with renal syndrome (HFRS) is a natural epidemic disease that can be caused by the Hantaan virus (HTNV). Malaria is caused by plasmodium and can be transmitted by a mosquito bite. The similar manifestations shared by these disorders pose a challenge for clinicians in differential diagnosis, in particular, coupled with a false-positive serological test.

PSMB2 plays an oncogenic role in glioma and correlates to the immune microenvironment.

There has been an upward trend in the incidence of glioma, with high recurrence and high mortality. The beta subunits of the 20S proteasome are encoded by the proteasome beta (PSMB) genes and may affect the proteasome's function in glioma, assembly and inhibitor binding. This study attempted to reveal the function of the proliferation and invasion of glioma cells, which is affected by proteasome 20S subunit beta 2 (PSMB2).

Clinical Characteristics and Long-Term Outcomes following Surgery Combined with Adjuvant Radiotherapy for Patients with Frontal Sinus Malignancies.

 Primary frontal sinus malignancies (FSMs) are the rarest sinonasal cancers. This study aimed to determine clinicopathologic characteristics of primary FSMs and provide long-term survival outcomes.  This study is a retrospective review.

Light-triggered photosynthetic engineered bacteria for enhanced-photodynamic therapy by relieving tumor hypoxic microenvironment.

Singlet oxygen (O) has received considerable research attention in photodynamic therapy (PDT) due to its cytotoxic solid features. However, the inherent hypoxic state of the tumor microenvironment (TME) leads to the meager O quantum yield of inorganic PDT reagents, and their application remains elusive. We developed a novel strategy to fabricate active photosynthetic bacteria/photosensitizer/photothermal agent hybrids for photosynthetic tumor oxygenation and PDT and PTT tumor therapy under different laser irradiation sources.

A four-generation family transmission chain of COVID-19 along the China-Myanmar border in October to November 2021.

Background: Foreign imported patients and within-household transmission have been the focus and difficulty of coronavirus disease 2019 (COVID-19) prevention and control, which has also posed challenges to border areas' management. However, household transmission caused by foreign imported cases has not been reported in China's border areas. This study aimed to reveal a clear family clustering transmission chain of COVID-19 caused by contact with Myanmar refugees along the China-Myanmar border during an outbreak in October to November 2021.

[Latest Research Findings on the Mechanism of Periodontal Pathogens in Cardiovascular Disease].

Cardiovascular disease (CVD) is a major cause of death worldwide. Research findings indicate that periodontal infection is an independent risk factor for CVD. Periodontal pathogens can cause cardiovascular diseases through various pathways, including direct invasion, induction of platelet activation and agglutination, immune inflammatory response, bacteremia, and oxidative stress.

A pH-responsive complex based on supramolecular organic framework for drug-resistant breast cancer therapy.

Chemotherapy is one of the main ways to treat breast cancer clinically. However, the multidrug resistance to anti-tumor drugs limits their clinical use. To overcome these drawbacks, development of drug delivery systems (DDSs) has attracted more and more attention in cancer therapy.

Self-Assembly of a Bilayer 2D Supramolecular Organic Framework in Water.

Accurate control of the layer number of orderly stacked 2D polymers has been an unsettled challenge in self-assembly. Herein we describe the fabrication of a bilayer 2D supramolecular organic framework from a monolayer 2D supramolecular organic framework in water by utilizing the cooperative coordination of a rod-like bipyridine ligands to zinc porphyrin subunits of the monolayer network. The monolayer supramolecular framework is prepared from the co-assembly of an octacationic zinc porphyrin monomer and cucurbit[8]uril (CB[8]) in water through CB[8]-encapsulation-promoted dimerization of 4-phenylpyridiunium subunits that the zinc porphyrin monomer bear.

Olive-Shaped Organic Cages: Synthesis and Remarkable Promotion of Hydrazone Condensation through Encapsulation in Water.

Two organic cages have been prepared in situ in water through the 2 + 3 hydrazone coupling of two pyridinium-derived trialdehydes and oxalohydrazide. The highly water-soluble cages encapsulate and solubilize linear neutral molecules. Such encapsulation has been applied for the promotion of both two- or three-component hydrazone condensation in water.

Dual-functional ionic porous organic framework for palladium scavenging and heterogeneous catalysis.

Porous organic frameworks (POFs) with predesigned structures and tunable porosities have been widely studied in adsorption and heterogeneous catalysis. Introducing ionic structure into the framework endows POFs with new functionalities that may extend their applications. Here, we report new applications for a guanidinium-based ionic POF (IPOF-Cl) in palladium scavenging and heterogeneous catalysis.

Are vitamins relevant to cancer risks? A Mendelian randomization investigation.

Objective: The relationship between vitamin intake and the occurrence of cancer is controversial. The aim of this study was to examine the genetic associations between vitamins D, E, and B and five cancers (i.e.

A Woven Supramolecular Metal-Organic Framework Comprising a Ruthenium Bis(terpyridine) Complex and Cucurbit[8]uril: Enhanced Catalytic Activity toward Alcohol Oxidation.

The self-assembly of a diamondoid woven supramolecular metal-organic framework wSMOF-1 has been achieved from intertwined [Ru(tpy) ] (tpy=2,2',6',2''-terpyridine) complex M1 and cucurbit[8]uril (CB[8]) in water, where the intermolecular dimers formed by the appended aromatic arms of M1 are encapsulated in CB[8]. wSMOF-1 exhibits ordered pore periodicity in both water and the solid state, as confirmed by a combination of H NMR spectroscopy, UV-vis absorption, isothermal titration calorimetry, dynamic light scattering, small angle X-ray scattering and selected area electron diffraction experiments. The woven framework has a pore aperture of 2.

Water-Soluble Flexible Organic Frameworks That Include and Deliver Proteins.

Four water-soluble hydrazone-based three-dimensional (3D) flexible organic frameworks have been synthesized from a semirigid tetracationic tetraaldehyde and four flexible dihydrazides. H NMR spectroscopy indicated the quantitative formation of in DO, while dynamic light scattering experiments revealed that, depending on the concentration, these porous frameworks display hydrodynamic diameters ranging from 50 to 120 nm.

Assembly of Discrete Chalcogenolate Clusters into a One-Dimensional Coordination Polymer with Enhanced Photocatalytic Activity and Stability.

Interlinking discrete supertetrahedral chalcogenolate clusters with conjugated bipyridine linkers form a one-dimensional coordination polymer, [CdAg(SPh)(DMF)(HO)(bpe)] (), displaying a broader visible-light absorption and a narrower band gap than those of the discrete cluster. More importantly, the coordination polymer demonstrates enhanced activity and stability for the photocatalytic degradation of organic dye in water.
