Crumpled graphite thin film balls were fabricated with Panasonic Pyrolytic Graphite Sheets (PGS). The fractal dimension, mechanical properties, and electrical conductivity of the crumpled PGS balls have been investigated. The universal local fractal dimension of the PGS balls is found to be 2.58, which is consistent with that of paper balls. The crumpled PGS balls show good mechanical property ...

Chick limb buds from 4- to 7-day-old embryos and sterna from 14-day-old embryos were labeled with [35S]sulfate, and the sulfated proteoglycans (PGS) were extracted either with associative (0.5 M guanidine . HCl) or dissociative (4.0 M guanidine . HCl) solvents. The existence of several populations of PGS is revealed in each age group when the limb extracts are analyzed on sucrose density gradie...

In this retrospective study, the utility of preimplantation genetic screening (PGS) in patients with advanced maternal age is evaluated. The patient population consisted of women aged 38-44years and included in a regular IVF programme with or without PGS analysis. Transfer rate, ongoing implantation rate and ongoing pregnancy rate were the main outcome parameters measured. A trend of better ong...

Extraction of the skin of newborn rat yielded two populations of galactosaminoglycan-containing proteoglycan: a Mr = 111,000-200,000 dermatan sulfate proteoglycan (DS-PG) with a Mr congruent to 55,000 core glycoprotein and a Mr congruent to 10(6) chondroitin sulfate proteoglycan (CS-PGs) composed of two subpopulations with different size core-glycoproteins (Mr congruent to 480,000 and 520,000)....

Plastoglobules (PGs) are oval or tubular lipid-rich structures present in all plastid types, but their specific functions are unclear. PGs contain quinones, alpha-tocopherol, and lipids and, in chromoplasts, carotenoids as well. It is not known whether PGs contain any enzymes or regulatory proteins. Here, we determined the proteome of PGs from chloroplasts of stressed and unstressed leaves of A...

OBJECTIVE Advanced maternal age (AMA) is an important factor in decreasing success of assisted reproductive technology by having a negative effect on the success rate of intra-cytoplasmic sperm injection (ICSI), particularly by increasing the rate of embryo aneuploidy. It has been suggested that the transfer of euploid embryos increases the implantation and pregnancy rates, and decreases the ab...

Phospholipase activation has been considered rate-limiting for ligand-stimulated prostaglandin (PG) synthesis. Constitutive prostaglandin synthase EC 1.14.99.1 (PGS-1) has been thought to convert arachidonate released following ligand stimulation to PGH2. However, a second prostaglandin synthase, TIS10/PGS-2, is inducible in many cell types, including fibroblasts and macrophages. We have used a...

Background and Objective: Accurate intraoperative identification viability assessment of the parathyroid glands (PGs) has always been a crucial but challenging aspect thyroid surgery. The traditional method, naked-eye (NE) assessment, is significantly associated with experience surgeon. Therefore, various methods have developed to help surgeons protect PGs, some benefits limitations. Recently, ...

Extracellular matrices (ECM) represent a complex network of proteins and glycosaminoglycans (GAGs) constituting the cell microenvironment including elastin, laminins, fibronectin, and GAG decorated proteoglycans (PGs). PGs are composed of independent structural domains, the sequences and arrangements of which are highly conserved and discretely glycosylated, thus determining a varying degree of...

Prostaglandins (PGs) are widely distributed throughout the gastrointestinal tract and affect a variety of gastrointestinal functions. The observation that PGs of the E and A series are potent inhibitors of gastric acid secretion and that PGs, especially the E compounds, are released into the gastric lumen during vagal or gastrin stimulation suggests a possible physiological role for these agent...
