Prostaglandins (PGs) play important roles in regulation of the functions of the hen oviduct. However, little is known about the expression and localization of the rate-limiting cyclooxygenases (COX-1 and COX-2) in the oviduct. The aim of this study was to determine the COXs expression and localization in the different segments of the oviduct and to investigate changes in their expression levels during the ovulatory cycle of laying hens. White Leghorn laying hens were killed at 0, 4, 7, 16 and 24 h after oviposition, and samples from the infundibulum, magnum, isthmus, uterus, and vagina were collected...

Chondroitin sulfate (CS) proteoglycans (PGs) are a family of complex molecules in the extracellular matrix and cell surface that regulate axon growth and guidance during development of the central nervous system. In this study, the expression of CSPGs was investigated in the mouse spinal cord at late embryonic and neonatal stages using CS-56 antibody. CS immunoreactivity was observed abundantly in ventral regions of spinal cord of embryonic day (E) 15 embryos. At E16 to E18, CS expression spread dorsally, but never reached the superficial layers of the dorsal horn...

Prostaglandins (PGs) play a critical role in porcine reproduction, of which prostaglandin E2 (PGE2) and prostaglandin F2α (PGF2α) exert antiluteolytic and luteolysis actions, respectively. As a rate-limiting enzyme, carbonyl reductase 1 (CBR1) catalyzes the conversion of PGE2 to PGF2α. A high ratio of PGE2:PGF2α is beneficial to the establishment and maintenance of porcine pregnancy. PG is essential for the establishment of pregnancy which resembles the proinflammatory response and nuclear factor κB (NF-κB) is involved in the process...

The significance of Helicobacter pylori (H. pylori) infection in pediatric abdominal pain remains poorly recognized. We examined associations of H. pylori infection and serum pepsinogens (PGs), as non-invasive markers of gastritis, with pediatric abdominal pain. A case-control study was conducted among 99 children aged 5-17 years admitted to one hospital for abdominal pain (cases) without an apparent organic reason. Using enzyme-linked immunosorbent assays, sera were tested and compared with 179 controls for anti-H...

In this study, highly reactive endo- and exo-polygalacturonases (PGs) were produced from the tobacco industry wastewater using immobilized Rhizopus oryzae. Compared with free cells, immobilized cells increased enzyme activity 2.8-fold and reduced production time to 24h by shake-flask production. Moreover, the immobilized cells enabled the semi-continuous production of enzymes through repeated-batch mode for seven consecutive cycles in a scale-up bioreactor. During the first five cycles, the average endo-PG and exo-PG activities reached 307...

Prostaglandins (PG), the products of cyclooxygenase-mediated conversion of arachidonic acid, become upregulated in many situations including allergic response, inflammation, injury, and exhibit variety of biological activities. Previous studies described barrier-enhancing and anti-inflammatory effects of PGE2 and PGI2 on vascular endothelial cells (EC). Yet, the effects of other PG members on EC barrier and inflammatory activation have not been systematically analyzed. This study compared effects of PGE2, PGI2, PGF2α, PGA2, PGJ2 and PGD2 on human pulmonary EC...

Due to its biomimetic mechanical properties to soft tissues, excellent biocompatibility and biodegradability, poly (glycerol sebacate) (PGS) has emerged as a representative bioelastomer and been widely used in biomedical engineering. However, the typical curing of PGS needs high temperature (>120 °C), high vacuum (>1 Torr), and long duration (>12 h), which limit its further applications. Accordingly, we designed, synthesized and characterized a photo/thermo dual curable polymer based on PGS. Treatment of PGS with 2-isocyanatoethyl methacrylate without additional reagents readily produced a methacrylated PGS (PGS-IM)...

OBJECTIVE: Proteoglycans (PGs) are multifunctional biomacromolecules of the extracellular matrix of collagen-based tissues. In teeth, besides a pivotal regulatory role on dentin biomineralization, PGs provide mechanical support to the mineralized tissue and compressive strength to the biosystem. This study assessed enzymatic protocols for selective PGs removal from demineralized dentin to determine the roles of these biomacromolecules in the bulk mechanical properties and biostability of type I collagen...

BACKGROUND: Purple glove syndrome (PGS) is a poorly understood severe adverse drug reaction that is typically associated with intravenous phenytoin administration. Although fosphenytoin is thought to circumvent this risk of PGS, we reveal a rare case of PGS in a patient treated with fosphenytoin therapy. CASE SUMMARY: A 71-year-old male with history of epilepsy was admitted for seizures and traumatic brain injury and intravenous fosphenytoin and levetiracetam were initiated...

Pathological gambling (PG) is a common and costly public health problem associated with impaired quality of life and high suicide rates. Despite its frequency in the general population, PG course is poorly understood in older adults who are especially vulnerable to its devastating consequences. We enrolled 175 subjects in a longitudinal study of gambling behavior: our case group of 53 older adults with PG (≥ 60 years), and two comparison groups including 72 younger adults with PG (< 40 years) and 50 older adults without PG (≥ 60 years)...

STUDY QUESTION: Can simultaneous detection of aneuploidies and genetic diseases or chromosomal aberrations in blastocysts reduce the chance of transferring embryos with low implantation potential, guaranteeing good clinical outcomes? SUMMARY ANSWER: The screening for chromosomal aneuploidies revealed that 50.6% of blastocysts diagnosed free of genetic disease or balanced, were aneuploid, therefore avoiding the transfer of blastocysts potentially resulting in implantation failures, miscarriages, or in some cases, in health affected live births...

The severity and course of inflammatory processes differ between women and men, but the biochemical mechanisms underlying these sex differences are elusive. Prostaglandins (PG) and leukotrienes (LT) are lipid mediators linked to inflammation. We demonstrated superior LT biosynthesis in human neutrophils and monocytes, and in mouse macrophages from females, and we confirmed these sex differences in vivo where female mice produced more LTs during zymosan-induced peritonitis versus males. Here, we report sex differences in PG production in neutrophils during acute inflammation...

Bioactive lipids regulate most physiological processes, from digestion to blood flow and from hemostasis to labor. Lipid mediators are also involved in multiple pathologies including cancer, autoimmunity or asthma. The pathological roles of lipid mediators are based on their intricate involvement in the immune system, which comprises source and target cells of these mediators. Based on their biosynthetic origin, bioactive lipids can be grouped into different classes (e.g. sphingolipids, formed from sphingosine or eicosanoids, formed from arachidonic acid)...

It is well documented that aneuploidy rate in preimplantation embryos increases with the mother's age, and at the same time the number of oocytes diminishes. Consequently, for patients of advanced maternal age two options are available to overcome these limitations: use of oocytes from young donors, or use of own oocytes coupled with preimplantation genetic screening (PGS) for 24 chromosomes. However, it is not clear which strategy might be more effective. The aim of this retrospective study was to evaluate outcomes of IVF cycles coupled with transfer of vitrified embryos from donor or autologous oocytes, both with or without PGS...

The aortic disease comprises a group of different pathologies of high prevalence, seriousness and ever changing by the medical and surgical investigations. Therefore cardiovascular scientific societies in USA, Europe and Asia have created Task Force on practice guidelines (PG) to develop, update and revise PG for aortic diseases. These documents issue recommendations on the diagnosis and management of different aortic diseases. The three societies agree on the recommendations about diagnostic tests and on the value of computed tomography and magnetic resonance as the main tools for the diagnosis and follow-up of aortic disease...

OBJECTIVES: Variable prevalence and treatment of breakthrough pain (BTP) in different clinical contexts are partially due to the lack of reliable/validated diagnostic tools with prognostic capability. We report the statistical basis and performance analysis of a novel BTP scoring system based on the naïve Bayes classifier (NBC) approach and an 11-item IQ-BTP validated questionnaire. This system aims at classifying potential BTP presence in three likelihood classes: "High," "Intermediate," and "Low...
