The genus Urtica belongs to the family Urticaceae. The plants of this genus are known as nettles or, quite often, as stinging nettles. These plants can be easily identified by the presence of stinging hairs. Urtica species have previously been used for various medicinal purposes. The history for the use of these plants for medicinal purposes starts from the Bronze Age (3000-2000 BC). Medicinally, the genus Urtica has been used to treat several disorders, such as cancer, rheumatoid arthritis, bronchitis, diarrhea, sprains, kidney stones, urinary tract infection, high blood pressure, hemorrhoids, flu, cough, fever, and ulcers...

Copolymer/water interfacial tensions of statistical copolymers of styrene / n-butyl acrylate were estimated by pendant drop tensiometry using an "inverse" configuration according to which a drop of water was formed in toluene/copolymer solutions. The study first involved the precise measurement of copolymer solutions density using pycnometry. Subsequently, interfacial tensions of copolymer solutions against water were plotted as a function of copolymer concentration in toluene. Several methods were explored to fit the experimental data and obtain estimates of copolymer/water interfacial tensions at 100 % copolymer concentration in toluene by extrapolation...

BACKGROUND: Chest computed tomography (CT), including high-resolution CT (HRCT), has become an integral part of modern healthcare. It enables the physician to arrive at a diagnosis using a noninvasive approach. Our practice has shown that various chest CT scans without intravenous (IV) contrast, including HRCT, have no proper clinical indication. For the same reason, we have assessed the appropriateness of chest CT without IV contrast based on the evidence-based American College of Radiology (ACR) appropriateness criteria...

Current studies offer little insight on how epigenetic remodeling of bone-specific chromatin maintains bone mass in vivo. Understanding this gap and precise mechanism is pivotal for future therapeutic innovation to prevent bone loss. Recently, we found that low bone mass is associated with decreased H3K27 acetylation (activating histone modification) of bone specific gene promoters. Here, we aim to elucidate the epigenetic mechanisms by which a miRNA cluster controls bone synthesis and homeostasis by regulating chromatin accessibility and H3K27 acetylation...

Actomyosin contractility is an essential element of many aspects of cellular biology and manifests as traction forces that cells exert on their surroundings. The central role of these forces makes them a novel principal therapeutic target in diverse diseases. This requires accurate and higher-capacity measurements of traction forces; however, existing methods are largely low throughput, limiting their utility in broader applications. To address this need, we employ Fourier-transform traction force microscopy in a parallelized 96-well format, which we refer to as contractile force screening...

For the last three decades, content-based image retrieval (CBIR) has been an active research area, representing a viable solution for retrieving similar images from an image repository. In this article, we propose a novel CBIR technique based on the visual words fusion of speeded-up robust features (SURF) and fast retina keypoint (FREAK) feature descriptors. SURF is a sparse descriptor whereas FREAK is a dense descriptor. Moreover, SURF is a scale and rotation-invariant descriptor that performs better in the case of repeatability, distinctiveness, and robustness...
