In this study, a catalog of β-cryptoxanthin (βCX) and its fatty acid esters (βCXFAs) in citrus fruits were constructed. The peel and pulp of
citrus fruits from nine Japanese cultivars and one foreign cultivar were
surveyed by supercritical fluid chromatography/triple quadrupole mass spectrometry
(SFC/QqQMS). In each citrus sample, the major components were βCX and its laurate ester, myristate
ester, palmitate ester, and oleate ester. However, the composition ratio of βCXFA varied with the citrus breed and
between the pulp and the peel of the fruit in most cultivars. The SFC/QqQMS
system could be used to obtain new information about βCXs and carry out further discussion
on the feature and tendency of each citrus variety.
attempts to apply techniques that are based on indirect measurements of
parameters that are believed to correlate to any material properties (or state)
in an in-line situation must by necessity identify a mathematical model of this
relationship. The most conventional approach is to use some empirically based
model. If the analysis instead is based on an analytical model of a physical
explanation, this trainee period can be minimized and the system is more
dynamic and less sensitive to changes within the chain of production. A
numerical solution to the inverse problem of ultrasonic crack detection is in
this case investigated. This solution is achieved by applying optimization
techniques to a realistic model of the ultrasonic defect detection situation.
This model includes a general model of an ultrasonic contact probe working as
transmitter and/or receiver and its interaction with the defect. The inverse
problem is reduced to minimization of a nonlinear least squares problem and is
performed with a quasi-Newton algorithm consisting of a locally convergent
SVD-Newton method combined with a backtracking line search algorithm. The set
of synthetic data the model is fitted with are generated both by numerical
integration and with the two-dimensional stationary-phase method while the
forward solver in the optimization procedure is based on the latter. In both
these cases, the convergence, in terms of numbers of iterations, is sufficient
when the initial guess is reasonably close.
Successful treatment with painful eccentric training for patients with chronic painful midportion Achilles tendinosis started research on pain mechanisms involving ultrasound + Doppler investigations and immunohistochemical analyses of tendon tissue specimens. This research has resulted in a better understanding of the pain mechanisms involved in the chronic painful Achilles and patellar tendon, and based on these findings new non tendon-invasive treatment methods beneficial for the patients have been invented. This is a mini review showing the background and research that resulted in the highly successful mini surgical treatments for mid-portion Achilles tendinopathy and proximal patellar tendinopathy.
