INTRODUCTION: There is evidence, indicate early compensatory axonal remodeling connections in the prenatal period, providing a favorable neurological outcome isolated anomalies of corpus callosum (CC). Mapping macromolecular proton fraction (MPF) proven method quantitative determination myelin, which has been adapted for studies. OBJECTIVE: To investigate relationship between CC and myelination...

In Xenopus embryos, the successive and rapid cell divisions that follow fertilization are accompanied by periodic oscillations of intracellular pH (pHi). Cycling of pHi occurs in phase with several other oscillatory activities, namely nuclear divisions, M phase-promoting factor (MPF) activity, and surface contraction waves (SCWs). We report that treatments that abolish cycling of MPF activity a...

The aim of this study was to examine the mechanomyogram (MMG) and force relationship of the first dorsal interosseous (FDI) muscle as well as the biceps brachii (BB) muscle during voluntary isometric ramp contractions, and to elucidate the MMG responses resulting from the intrinsic motor unit (MU) activation strategy of FDI muscle with reference to the MMG of BB muscle. The subjects were asked ...

The objective of this study was to determine the effects of grasp conditions (types of grasp, grasp width, glove and types of coupling) on maximal pushing force (MPF) and required pinch force (RPF) during snap fit assembly. The results indicated that the type of grasp, the type of coupling and wearing gloves have significant (p

BACKGROUND In the running community, a forefoot strike (FFS) pattern is increasingly preferred compared with a rearfoot strike (RFS) pattern. However, it has not been fully understood which strike pattern may better reduce adverse joint forces within the different joints of the lower extremity. PURPOSE To analyze the 3-dimensional (3D) stress pattern in the ankle, knee, and hip joint in runne...

Plasmid conjugation systems are composed of two components, the DNA transfer and replication system, or Dtr, and the mating pair formation system, or Mpf. During conjugal transfer an essential factor, called the coupling protein, is thought to interface the Dtr, in the form of the relaxosome, with the Mpf, in the form of the mating bridge. These proteins, such as TraG from the IncP1 plasmid RP4...

Momentary fatigue is an important variable in resistance training periodization programs. Although several studies have examined neuromuscular activity during single repetitions of resistance training, information is lacking in regard to neuromuscular fatigue indices throughout a full resistance training bout. The purpose of this study was to evaluate muscle activity during a shoulder resistanc...

Abstract: Solute segregation significantly affects material propert ies and is an essential issue in powder-bed fusion（PBF）type additional manufacturing（AM）of nickel-based superalloys. In the present study, we have investigated effects of solidification conditions temperature gradients rates on behavior Hastelloy-X Ni-based superalloy using multi- phase field（MPF）simulation. To evaluate liquati...

M phase-promoting factor (MPF) consists of a p34cdc2 (cdc2) kinase and cyclin B complex which in its active form promotes G2 to M transition. The role of MPF in G2 arrest following DNA damage, however, has remained largely uncharacterized. We have investigated whether nitrogen mustard (HN2) interfered with either the formation of MPF or its activation. For this purpose, we measured cdc2 kinase ...

DNA transfer by bacterial conjugation requires a mating pair formation (Mpf) system that specifies functions for establishing the physical contact between the donor and the recipient cell and for DNA transport across membranes. Plasmid RP4 (IncP alpha) contains two transfer regions designated Tra1 and Tra2, both of which contribute to Mpf. Twelve components are essential for Mpf, TraF of Tra1 a...
