Corticotropin-releasing hormone interacts with interleukin-1 to regulate prostaglandin H synthase-2 expression in human myometrium during pregnancy and labor [PDF]

, 2013
Context: The onset of labor appears to involve the activation of myometrial inflammatory pathways, and transcription factors such as nuclear factor-κB (NF-κB) control expression of the contraction-associated proteins required to induce a procontractile ...

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Management of early pregnancy loss with mifepristone and misoprostol: clinical predictors of treatment success from a randomized trial. [PDF]

, 2020
BackgroundEarly pregnancy loss is a common event in the first trimester, occurring in 15%-20% of confirmed pregnancies. A common evidence-based medical regimen for early pregnancy loss uses misoprostol, a prostaglandin E1 analog, with a dosage of 800 μg,

When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

Annals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

Activation of Extracellular-signal Regulated Kinase (ERK1/2) by Fluid Shear is Ca\u3csup\u3e2+\u3c/sup\u3e- and ATP-dependent in MC3T3-E1 Osteoblasts [PDF]

, 2008
To determine the role of Ca2+ signaling in activation of the Mitogen-Activated Protein Kinase (MAPK) pathway, we subjected MC3T3-E1 pre-osteoblastic cells to inhibitors of Ca2+ signaling during application of fluid shear stress (FSS).

Prothrombotic Activation of Platelet Pannexin 1 Channels in Antiphospholipid Syndrome

Arthritis &Rheumatology, Accepted Article.
Background ATP is released from platelets through both degranulation and pannexin‐1 (PANX1) channels. ATP then activates P2X receptors to amplify platelet activation via calcium‐dependent signaling. Objective To evaluate the role of platelet PANX1 channels in the pathophysiology of antiphospholipid syndrome (APS), an acquired thrombo‐inflammatory ...

Misoprostol-induced pulmonary edema in a parturient with postpartum cardiomyopathy

Journal of Obstetric Anaesthesia and Critical Care, 2011
Misoprostol, a synthetic prostaglandin E1 (PGE1) analogue, although not the first-line drug in the management of postpartum hemorrhage, is frequently used for this purpose due to its safety profile and cost-effectiveness.

Functional Critical Aortic Stenosis with Transient Retrograde Flow in a Neonate with Left Diaphragmatic Hernia [PDF]

, 2012
We report a neonate with left congenital diaphragmatic hernia and severe left ventricular dysfunction, in whom the blood flow in the transverse arch and its branches was supported in a retrograde fashion by patent ductus arteriosus.
