Compliance mismatch is a significant challenge to long-term patency in small-diameter bypass grafts because it causes intimal hyperplasia and ultimately graft occlusion. Current engineered grafts are typically stiff with high burst pressure but low compliance and low elastin expression. We postulated that engineering small arteries on elastomeric scaffolds under dynamic mechanical stimulation w...

Plants perceive microbial invaders using pattern recognition receptors that recognize microbe-associated molecular patterns. In this study, we identified RESPONSIVENESS TO BOTRYTIS POLYGALACTURONASES1 (RBPG1), an Arabidopsis (Arabidopsis thaliana) leucine-rich repeat receptor-like protein, AtRLP42, that recognizes fungal endopolygalacturonases (PGs) and acts as a novel microbe-associated molecu...

Polygalacturonase (PG) is an enzyme in the salivary glands of piercing-sucking mirid bugs (Hemiptera: Miridae) that plays a key role in plant feeding and injury. By constructing a full-length cDNA library, we cloned and characterized 14 PG genes from the salivary glands of Apolygus lucorum, a pestiferous mirid bug in cotton, fruit trees and other crops in China. BLAST search analysis showed tha...

Poly(glycerol sebacate) methacrylate (PGS-M) has tunable mechanical properties, making it suitable for soft tissue engineering.

This paper reviews the role of prostaglandins (PGs) in cancer. Specific topics of discussion include: (1) the potential use of PGs as tumor markers, (2) PG mediation of hypercalcemia of cancer, and (3) the use of PG synthesis inhibitors in cancer therapy.

Evidence exists implicating prostaglandins as mediators of asthma and of chronic inflammation in the lung. In addition to their spasmogenic effects, PGs are also potent in vitro regulators of mediator secretion by basophils, mast cells, or lymphocytes. These regulatory effects of E-series PGs may have considerable significance in drug design and evaluation in both asthma and chronic inflammation.

Pathological gambling is a behavioral addiction characterized by a chronic failure to resist the urge to gamble. It shares many similarities with drug addiction. Glucocorticoid hormones including cortisol are thought to play a key role in the vulnerability to addictive behaviors, by acting on the mesolimbic reward pathway. Based on our previous report of an imbalanced sensitivity to monetary ve...

BackgroundDespite the increasing use of intraoperative facial nerve monitoring during parotid gland surgery (PGS) and improvement in preoperative radiological assessment, injury (FNI) remains most severe complication after PGS. Until now, no studies have been published regarding application machine learning (ML) for predicting FNI We hypothesize that ML would improve prediction patients at risk...

In this study, phosphorylation of c-Jun N-terminal kinase (JNK) by the prothoracicotropic hormone (PTTH) was investigated in prothoracic glands (PGs) of the silkworm, Bombyx mori. Results showed that JNK phosphorylation was stimulated by the PTTH in time- and dose-dependent manners. In vitro activation of JNK phosphorylation in PGs by the PTTH was also confirmed in an in vivo experiment, in whi...

OBJECTIVE To compare the incidence of numerical chromosomal abnormalities (NCAs) reported after preimplantation genetic screening (PGS) analysis compared with that reported after cytogenetic analysis of products of conception after spontaneous abortion. DESIGN Retrospective study. SETTING Private academic in vitro fertilization center. PATIENT(S) Cytogenetic reports of patients who underw...
