Gelatin-resorcin-formalin (GRF) glue was developed by Braunwald and Tatooles in 1964. Initially, it was mainly used as a hemostatic agent by gastrointestinal surgeons and urologists. In 1977, Bachet et al. used GRF glue as an adhesive and hemostatic material for aortic surgery and reported that it was very useful. The use of GRF glue dramatically improved the outcomes of surgery for Stanford ty...

Objectves Considering social variables influencing psychological well-being and protecting from development of mental disease, social support received great attention. In recent years the focus shifted toward more general constructs that can account for stability and coherence of the scheme that each person applies to relate to the social word as a whole. The construct of social connectedness s...

Human pancreatic growth hormone releasing factor (GRF (1-44)) is the parent molecule of several peptides recently extracted from pancreatic tumours associated with acromegaly. A study was conducted to examine its effects on the release of growth hormone in normal volunteers and in patients with hypopituitarism and acromegaly. GRF (1-44) dose dependently stimulated the release of growth hormone ...

In rodents, the Ras-specific guanine-nucleotide exchange factor (Ras-GRF) is expressed in different areas of the brain and, at a reduced level, also in the spinal cord. No expression of the 140 kDa Ras-GRF was detected in dorsal root ganglia and all other tissues tested. Analysis of primary cultures derived from brain reveals that this exchange factor is only present in neurons of the central n...

Background: The exponential growth of smartphones has afforded many users with ubiquitous access to socialization as seen in the various mobile apps used to communicate and connect with others. The present study employed mixed-method approaches to analyse the impact of phubbing on social connectedness among adolescents in Malaysia. Methods:</stron...

Recent literature supports the importance of horizontal ground reaction force (GRF) production for sprint acceleration performance. Modeling and clinical studies have shown that the hip extensors are very likely contributors to sprint acceleration performance. We experimentally tested the role of the hip extensors in horizontal GRF production during short, maximal, treadmill sprint acceleration...

Wearable sensors for gait analysis are attracting wide interest. In this paper, a wearable ground reaction force (GRF) sensor system and its application to measure extrinsic gait variability are presented. To validate the GRF and centre of pressure (CoP) measurements of the sensor system and examine the effectiveness of the proposed method for gait analysis, we conducted an experimental study o...

Abnormal subtalar joint function and the consequent rotation of the tibia during walking are thought to contribute to patellofemoral pain syndrome (PFPS). The purpose of this study was to measure rearfoot and tibia motion, and the ground reaction force (GRF) during the stance phase of walking in subjects with PFPS and compare them to healthy subjects. A four camera motion analysis system with a...

The reliability of distributed systems and computer networks have been modeled by a probabilistic network or a graph G. Computing the residual connectedness reliability (RCR), denoted by R(G), under the node fault model is very useful, but is an NP−hard problem. Since it may need exponential time of the network size to compute the exact value of R(G), it is important to calculate its tight appr...

Given a principal ideal domain R of characteristic zero, containing 1/2, and a two-cone X of appropriate connectedness and dimension, we present a sufficient algebraic condition, in terms of Adams-Hilton models, for the Hopf algebra FH(ΩX;R) to be isomorphic with the universal enveloping algebra of some R-free graded Lie algebra; as usual, F stands for free part, H for homology, and Ω for the M...
