A gas decompression technique was used to determine the breaking strength of cell walls of single cells. Breaking strengths of the bacterium Salmonella typhimurium and the unicellular green alga Chlamydomonas eugametos were 100 and 95 atmospheres, respectively, while those of sporophytes of the water mold Blastocladiella emersonii were 65 atmospheres, and those of suspension cultured cells of c...

AIMS/HYPOTHESIS Topical application of CTGF/CCN2 to rodent diabetic and control wounds was examined. In parallel research, correlation of CTGF wound fluid levels with healing rate in human diabetic foot ulcers was undertaken. METHODS Full thickness cutaneous wounds in diabetic and nondiabetic control rats were treated topically with 1 μg rhCTGF or vehicle alone, on 2 consecutive days. Wound h...

We uncover that the breaking point of the  -symmetry in optical waveguide arrays has a dramatic impact on light localization induced by the off-diagonal disorder. Specifically, when the gain/loss control parameter approaches a critical value at which  -symmetry breaking occurs, a fast growth of the coupling between neighboring waveguides causes diffraction to dominate to an extent that ligh...

morinda citrifolia (noni) has been traditionally used for bone and wound healing.   the present study was carried out to investigate the effect of morinda citrifolia leaves on experimental wounds and lipid peroxide levels in rats. effect of aqueous extract of leaves of morinda citrifolia (200 mg/kg) on excision, resutured incision and dead space wound models were studied. measurement of blood m...

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

We use atomic force microscopy to image grain boundaries and ripples in graphene membranes obtained by chemical vapor deposition. Nanoindentation measurements reveal that out-of-plane ripples effectively soften graphene's in-plane stiffness. Furthermore, grain boundaries significantly decrease the breaking strength of these membranes. Molecular dynamics simulations reveal that grain boundaries ...

We study one dimensional supersymmetric (SUSY) quantum mechanics of a spin 1 2 particle moving in a rotating magnetic field and scalar potential. We also discuss SUSY breaking and it is shown that SUSY breaking essentially depends on the strength and period of the magnetic field. For a purely rotating magnetic field the eigenvalue problem is solved exactly and two band energy spectrum is found.

Abstract The fatigue of running sportswear is reflected in the caused by tightness tights on skin surface limbs, trunk, and other parts during long-term sports. However, current research not deep enough. Therefore, purpose this study to mechanism based BP neural network. This article first takes as starting point uses myoelectricity index a physiological quantity means combine clothing with spo...

Background & Aims: Grip strength plays a fundamental role in many daily activities of upper extremities. Reduced grip strength is common in patients with some musculoskeletal disorders in upper extremities. Kinesio taping of the forearm area might help to facilitate muscle contraction through stimulating the skin mechanoreceptors and consequently increasing sensory feedbacks around the taped ar...
