Role of Oral Bacteria in the Development of Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma (OSCC) is an invasive epithelial neoplasm that is influenced by various risk factors, with a low survival rate and an increasing death rate. In the past few years, with the verification of the close relationship between different types of cancers and the microbiome, research has focused on the compositional changes of oral bacteria and their role in OSCC. Generally, oral bacteria can participate in OSCC development by promoting cell proliferation and angiogenesis, influencing normal apoptosis, facilitating invasion and metastasis, and assisting cancer stem cells.

In Situ Self-Assembly of Nanoparticles into Waxberry-Like Starch Microspheres Enhanced the Mechanical Strength, Fatigue Resistance, and Adhesiveness of Hydrogels.

Owing to the diminishing resources and growing awareness of environmental issues, significant scientific attention has been paid to the development of physical gel materials using renewable and low-cost natural resources. Inspired by the strengthened mechanism of double-network and nanocomposite (NC) gels, we report a facile and green method to realize a mechanically stiff, fatigue-resistant, and adhesive-debranched waxy corn starch/poly(vinyl alcohol) double-crosslinked NC gel (W-Gel) skeleton material with dynamic noncovalent bonds. The in situ formation of debranched starch nanoparticles leads to self-assembly into three-dimensional waxberry-like microspheres, which act as physical cross-linkers by embedding themselves within network skeleton structures.

Adaptive high-dynamic-range Fourier ptychography microscopy data acquisition with a red-green-blue camera.

Fourier ptychography microscopy is a powerful tool for wide-field and high-spatial-resolution imaging. It can achieve a large field of view and high-spatial-resolution imaging with a low numerical aperture objective by capturing a series of low-resolution (LR) images that contain the information of different spatial frequencies and then stitching them together in the Fourier domain. Furthermore, the phase information of the object can also be recovered simultaneously.

The aim of present study was to evaluate the potential effects of oral liquid (RCOL) on exhaustive exercise (EE)-induced fatigue in mice. Male Institute of Cancer Research mice from five treatment groups (n=10 per group) were orally administered with sterilized water for the Control and EE groups and/or RCOL at doses of 1.02, 3.

Prevention strategies of mother-to-child transmission of hepatitis B virus (HBV) infection.

Chronic hepatitis B virus (HBV) infection caused by mother-to-child transmission (MTCT, also known as vertical transmission) during the perinatal period is a major public health problem worldwide. Despite the availability of the combined active-passive immunization with a hepatitis B vaccine and hepatitis B immunoglobulin after birth, about 9% of newborns are still infected with HBV, especially those born to hepatitis B e antigen (HBeAg)-positive mothers. Currently, the management of HBV infection during pregnancy remains controversial.

Elderly patients with hypertension self-perceived of aging status and compliance with medical behaviour.

At present, it is rare for studies to be performed on the impact of self-perceptions of aging on the compliance behaviour of elderly people.The present study explored the relationship between self-perceived of aging level and compliance behavior among asample of elderly Chinese hypertension patients. Participants (N=1129) were recruited from four community health service centres and two township hospitals in Suzhou.

Energy and Environment Performance of Resource-Based Cities in China: A Non-Parametric Approach for Estimating Hyperbolic Distance Function.

Scientific determination of energy and environmental efficiency and productivity is the key foundation of green development policy-making. The hyperbolic distance function (HDF) model can deal with both desirable output and undesirable output asymmetrically, and measure efficiency from the perspective of "increasing production and reducing pollution". In this paper, a nonparametric linear estimation method of an HDF model including uncontrollable index and undesirable output is proposed.

A foreign body in the blood vessel: A diagnostic and therapeutic dilemma.

Foreign body(FB) in soft tissue is a common injury in trauma, but it is rare for FB to enter the blood vessel. Typical causes of intravascular FB include iatrogenic and non-iatrogenic factors.A 65-year-old Chinese worker's left hand was hit by two colliding metal blocks while operating a machine tool.

A pH-responsive dissociable mesoporous silica-based nanoplatform enabling efficient dual-drug co-delivery and rapid clearance for cancer therapy.

The balance between tumor accumulation and renal clearance has severely limited the efficacy of mesoporous silica-based drug nanocarriers in cancer therapy. Herein, a pH-responsive dissociable mesoporous silica-based nanoplatform with efficient dual-drug co-delivery, tumor accumulation and rapid clearance for cancer therapy is achieved by adjusting the wetting of the mesoporous silica surface. At pH 7.

Green fabrication and characterization of debranched starch nanoparticles via ultrasonication combined with recrystallization.

With recent advances in nanotechnology, debranched starch nanoparticle (DBS-NP) materials have attracted considerable interest from the fields of functional food, biomedicine, and material science, thanks to their small size, biodegradability, biocompatibility, sustainability, and non-hazardous effects on health and the environment. In this study, DBS-NP was fabricated using an eco-friendly method involving ultrasonication combined with recrystallization. The effects of ultrasonication and recrystallization times on the morphology, particle size, and crystal structure of the DBS-NPs were systematically investigated.

Dynamic Deformation Measurement of Specular Surface with Deflectometry and Speckle Digital Image Correlation.

The deformation measurement of a specular surface is of great importance during the quality inspection and installation of optical elements or wafers, especially those with large apertures. We propose a deflectometry method with speckle digital image correlation (DeSDIC) to realize the dynamic and high-accuracy measurement of the deformation on specular surfaces, with a simple system structure and robustness to noises and environmental vibrations. Random speckle pattern displayed on liquid crystal display is reflected by the original surface under test (SUT), and the distorted pattern is recorded by a camera.

Resveratrol-loaded core-shell nanostructured delivery systems: Cyclodextrin-based metal-organic nanocapsules prepared by ionic gelation.

In this study, cyclodextrin metal-organic framework/chitosan (CD-MOF/CS) nanocapsules, which have a hydrophobic core and a hydrophilic shell, were fabricated as delivery systems for bioactive agents. The nanocapsules were prepared by electrostatic deposition of cationic chitosan onto the anionic CD-MOF core. The presence of the CS coating reduced the mean diameter and polydispersity index of the nanocapsules, which was attributed to their ability to inhibit particle aggregation.
