Novel Anti-Viral Properties of the Herbal Extract of against Influenza A Virus.

Gu-Sui-Bu, the dried rhizome of , is a traditional Chinese herbal remedy with a significant history of treating osteoporosis and inflammatory conditions. However, its potential as an anti-influenza agent and its underlying mechanisms of action remain unexplored. To obtain a more potent extract from and gain insights into its mechanism of action against influenza A virus (IAV), we utilized a partitioning process involving organic solvents and water, resulting in the isolation of butanolic subfractions of the extract (DMBE).

[Impact of the COVID-19 Pandemic on Health-Related Quality of Life in Older Adults With Preoperative Knee Osteoarthritis].

Background: Knee osteoarthritis is prevalent in older adults worldwide. Quality of life was negatively affected by the COVID-19 pandemic.

Purpose: This study was designed to examine osteoarthritis severity and health-related quality of life (QOL) in older adults with knee osteoarthritis before total knee replacement during the COVID-19 pandemic and to identify the related predictors of QOL.

Association of Backscattered Ultrasonographic Imaging of the Tongue With Severity of Obstructive Sleep Apnea in Adults.

Importance: Determining interventions to manage obstructive sleep apnea (OSA) depends on clinical examination, polysomnography (PSG) results, and imaging analysis. There remains the need of a noninvasive and cost-effective way to correlate relevant upper airway anatomy with severity of OSA to direct treatment and optimize outcome.

Objective: To determine whether backscattered ultrasonographic imaging (BUI) analysis of the tongue is associated with severity of OSA in adults.

Longitudinal shear wave elasticity measurements of millimeter-sized biomaterials using a single-element transducer platform.

Temporal variations of the extracellular matrix (ECM) stiffness profoundly impact cellular behaviors, possibly more significantly than the influence of static stiffness. Three-dimensional (3D) cell cultures with tunable matrix stiffness have been utilized to characterize the mechanobiological interactions of elasticity-mediated cellular behaviors. Conventional studies usually perform static interrogations of elasticity at micro-scale resolution.

Laser-speckle-contrast projection tomography for three-dimensional shear wave imaging.

Laser-speckle-contrast shear wave (LSC-SW) imaging is an optical method for tracking the propagation of a transient shear wave. With high spatial resolution and sensitivity in detecting displacements, this method is suitable for performing mechanical measurements in vitro. Here, we present a LSC-SW tomographic imaging system for visualizing the propagating shear wave wavefront in four dimensions [i.

Shear Wave Elasticity Measurements of Three-Dimensional Cancer Cell Cultures Using Laser Speckle Contrast Imaging.

Shear wave elastography (SWE) has been widely adopted for clinical in vivo imaging of tissue elasticity for disease diagnosis, and this modality can be a valuable tool for in vitro mechanobiology studies but its full potential has yet to be explored. Here we present a laser speckle contrast SWE system for noncontact monitoring the spatiotemporal changes of the extracellular matrix (ECM) stiffness in three-dimensional cancer cell culture system while providing submillimeter spatial resolution and temporal resolution of 10 s. The shear modulus measured was found to be strongly correlated with the ECM fiber density in two types of cell culture system (r = 0.

Exosome purification based on PEG-coated Fe3O4 nanoparticles.

Cancer cells secrete many exosomes, which facilitate metastasis and the later growth of cancer. For early cancer diagnosis, the detection of exosomes is a crucial step. Exosomes exist in biological fluid, such as blood, which contains various proteins.

Amelioration of estrogen-deficiency-induced obesity by .

Menopausal transition in women initiates with declining estrogen levels and is followed by significant changes in their physiological characteristics. These changes often lead to medical conditions, such as obesity, which is correlated with chronic low-grade/subclinical inflammation. L.

Attenuation of Oxidative Stress-Induced Cell Apoptosis in Schwann RSC96 Cells by Aqueous Extract.

Cell transplantation therapy of Schwann cells (SCs) is a promising therapeutic strategy after spinal cord injury. However, challenges such as oxidative stress hinder satisfactory cell viability and intervention for enhancing SCs survival is critical throughout the transplantation procedures. widely used as a folk medicine in many countries, has therapeutic and anti-oxidative properties and may protect SCs survival.

aqueous extract reduces plasma lipid in hypercholesterol-fed hamsters.

Hyperlipidemia is a significant risk factor in the development of atherosclerosis and related diseases which are major health problem in many developed and developing countries that can lead to fatality due to the changes in lifestyle and dietary habits in this modern age. In the present study, the aqueous extract (OGE) was tested for the lowering effect on the serum lipid level of male hamsters on a high-fat (12%) and high-cholesterol (0.2%) diet (HFCD).

Three-dimensional shear wave imaging based on full-field laser speckle contrast imaging with one-dimensional mechanical scanning.

The high imaging resolution and motion sensitivity of optical-based shear wave detection has made it an attractive technique in biomechanics studies with potential for improving the capabilities of shear wave elasticity imaging. In this study we implemented laser speckle contrast imaging for two-dimensional (X-Z) tracking of transient shear wave propagation in agarose phantoms. The mechanical disturbances induced by the propagation of the shear wave caused temporal and spatial fluctuations in the local speckle pattern, which manifested as local blurring.

Ocimum gratissimum is effective in prevention against liver fibrosis in vivo and in vitro.

Ocimum gratissimum is a traditional herb commonly found in tropical regions, which prevents free radical damage and protects the liver from oxidative stress. In this study, we tested in vivo and in vitro the effectiveness of O. gratissimum extracts (OGEs) in anti-hepatic fibrosis in rats.

Novel target genes responsive to apoptotic activity by Ocimum gratissimum in human osteosarcoma cells.

Osteosarcoma (OS) is a type of bone cancer. Eighty percent of this tumor will metastasize to the lungs or liver, and as a result, patients generally need chemotherapy to improve survival possibility. Recently, antitumor activity has been reported in Ocimum gratissimum aqueous extract (OGE), which has been the focus of recent extensive studies on therapeutic strategies due to its antioxidant properties.

Expression of protein kinase Cα and the MZF-1 and elk-1 transcription factors in human bladder transitional cell carcinoma cells.

In a recent study on hepatocellular carcinoma (HCC), we have shown that the transcription factors Myeloid Zinc Finger-1 (MZF-1) and Ets-like-protein 1 (Elk-1) are significantly related to protein kinase C alpha (PKCα) expression. The purpose of this study was to determine the correlation of the expression of PKCα with the expression of Elk-1 and MZF-1 in various differentiated urinary bladder transitional cell carcinoma (TCC) cell lines: 5637, BFTC905, TSGH8301, HT1376 and HT1197 cells. The malignant potential in the five TCC cell lines was examined by using cell proliferation/migration/invasion assay and the protein and mRNA levels of PKCα, ElK-1 and MZF-1 were examined by Western blot and RT-PCR analysis.
