These include effects as an anti-inflammatory and an antitumour compound. The purpose of this study was to investigate and compare any potential antigrowth effects of resveratrol and two of its derivatives, acetyl-resveratrol and polydatin, on 3D cell aggregates of the EGFR/Her-2 positive and negative ovarian cancer cell lines SKOV-3 and OVCAR-8, respectively.

Dexamethazone protects against Escherichia coli induced sickness behavior in rats.

Systemic bacterial infection results in systemic inflammatory response syndrome due to the release of lipopolysaccharide (LPS) in blood that can lead to multiple organ failure, shock, and potentially death. Other impact, LPS exposure produces robust increase in anxiety-like behavior, suppression of locomotor, exploratory activity, and reduced social behavior. The therapeutic use of glucocorticoids in septic shock remains one of the first-aid approaches for their anti-inflammatory properties.

Insulinoma-Associated Protein 1 Is a Crucial Regulator of Neuroendocrine Differentiation in Lung Cancer.

Insulinoma-associated protein 1 (INSM1) is expressed exclusively in embryonic developing neuroendocrine (NE) tissues. INSM1 gene expression is specific for small-cell lung cancer (SCLC), along with achaete-scute homolog-like 1 (ASCL1) and several NE molecules, such as chromogranin A, synaptophysin, and neural cell adhesion molecule 1. However, the underlying biological role of INSM1 in lung cancer remains largely unknown.

Analytical and numerical modeling of non-collinear shear wave mixing at an imperfect interface.

Non-collinear shear wave mixing at an imperfect interface between two solids can be exploited for nonlinear ultrasonic assessment of bond quality. In this study we developed two analytical models for nonlinear imperfect interfaces. The first model uses a finite nonlinear interfacial stiffness representation of an imperfect interface of vanishing thickness, while the second model relies on a thin nonlinear interphase layer to represent an imperfect interface region.

Therapeutic Potential of Date Palm Pollen for Testicular Dysfunction Induced by Thyroid Disorders in Male Rats.

β-elemene inhibits monocyte-endothelial cells interactions via reactive oxygen species/MAPK/NF-κB signaling pathway in vitro.

The recruitment of monocytes to the active endothelial cells is an early step in the formation of atherosclerotic lesions; therefore, the inhibition of monocyte-endothelial cells interactions may serve as a potential therapeutic strategy for atherosclerosis. Recent studies suggest that β-elemene can protect against atherosclerosis in vivo and vitro; however, the mechanism underlying the anti-atherosclerotic effect by β-elemene is not clear yet. In this study, we aimed to investigate the effects of β-elemene on the monocyte-endothelial cells interactions in the initiation of atherosclerosis in vitro.

Neoplastic lesions in CADASIL syndrome: report of an autopsied Japanese case.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is one of the most common heritable causes of stroke and dementia in adults. The gene involved in the pathogenesis of CADASIL is Notch3; in which mutations affect the number of cysteine residues in its extracellular domain, causing its accumulation in small arteries and arterioles of the affected individuals. Besides the usual neurological and vascular findings that have been well-documented in CADASIL patients, this paper additionally reports multiple neoplastic lesions that were observed in an autopsy case of CADASIL patient; that could be related to Notch3 mutation.

Intrapartum assessment of caput succedaneum by transperineal ultrasound: a two-centre pilot study.
