Sarcomatoid Carcinoma Arising from Mature Cystic Teratoma
Ho-Chang Lee1, Seung-Myoung Son, Yong-Moon Lee, Ji Hae Koo, Song-Yi Choi, Ok-Jun Lee, Eun-Hwan Jeong 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.2
Malignant transformation of mature cystic teratoma (MCT) is rare. Sarcomatoid carcinoma is a neoplasm comprising malignant mesenchymal cells and a conventional carcinomatous area. Here, we report on a case of sarcomatoid carcinoma arising from an MCT in the left ovary of a 45-year-old female. A unilocular cyst consistent with MCT was observed; however, a nodule within the cyst was confirmed from the resected ovary. Microscopically, the nodule showed both squamous cell carcinoma and pleomorphic sarcomatous components admixing with each other. Lining epithelial cells at the periphery of the main tumor showed squamous metaplasia. When a sarcomatous component is observed in the ovary tumor, it is important to find a squamous cell component, either benign or malignant.

A simple tuning methods of PI, PD and PID controller are proposed for an integrating process with time delay. This is based on matching the coefficients of corresponding powers of s in the numerator and that in the denominator of the closed-loop transfer function. For set-point tracking problem, the derived controller is found to be a PD controller which is shown by Lee's tuning rule based on minimizing the performance indexes (lSE, IAE, ITAE) using a real-coded genetic algorithm. A method can be also proposed PI, PID controllers according to tuning parameter lambda (A) similar to IMC method. Simulation example is given to illustrate the set-point tracking performance of the proposed method.

<P>The recent trend in automotive industry is characterized by the replacement of existing metal materials with composite ones or the combination of both for lightweight parts. This study 1) created single lap joint specimens of SPCC used for automobile frame and four adhesives; epoxy, urethane, acrylic, mixed (urethane and acrylic) and rivets to bind dissimilar materials of CFRP necessary for weight lightening, and 2) performed a tensile shear test on adhesive bonding versus adhesive bonding with rivets. In summary, this study investigated on the bonding performance of different specimens: bonding strength, shapes of the failure surface, and the effect of rivets on bond strength.</P>

<P>Most intrinsically healable polymers feature a soft nature and high flowability that arise from the reversible formation of bonds (<I>e.g.</I>, cross-linkages). Unfortunately, a trade-off relationship between mechanical strength and healing capability is observed for the majority of these polymers, which necessitates the search for better alternatives. Herein, we synthesized a urethane acrylate-based intrinsically healable material with enhanced mechanical properties, demonstrating that this enhancement originates from the presence of UV curing-produced dynamic urea bonds acting as reversible cross-linkages. The synthesized polymer was hybridized with silver nanowires (AgNWs) to afford a transparent pressure-sensitive e-skin capable of irradiation-induced healing, <I>i.e.</I>, the heating of AgNWs by a series of intense pulsed light (IPL) irradiations allowed one to instantly and rapidly repair the cutting marks or scratches artificially formed on e-skin sensors. The healing ability was originated from the enhanced flowability and thermal expansion of the polymer during IPL irradiation. Consecutive cutting-healing cycling showed that the cutting marks formed at the same locations could be effectively repaired for up to five times. The fringing effect-associated capacitance of a AgNW tandem compound pattern significantly increased with increasing pressure applied to the sensor surface, and the electric function of damaged sensors was successfully restored by irradiation-induced healing.</P>

<P><B>Abstract</B></P> <P>A lifetime extending molecular design approach by increasing the bond dissociation energy of the thermally activated delayed fluorescent (TADF) emitters was investigated. A TADF emitter with a molecular design having the donors in a planar manner, 4-(9<I>H</I>-carbazol-9-yl)-6-(9,9″-diphenyl-9<I>H</I>,9′<I>H</I>,9″<I>H</I>-[3,3′:6′,3″-tercarbazol]-9′-yl)isophthalonitrile (TCzIPN), was compared with state of the art green TADF emitter. The two emitters were green TADF emitters with similar peak wavelengths, but the TCzIPN exhibited three times longer lifetime than the current TADF emitter. Analysis of bond dissociation energy of the TADF emitters revealed that the weak CN bond of the TCzIPN was stabilized by small dihedral angle between donor and an aromatic linker. This was confirmed by exciton stability test of the emitters, and the CN bond stabilization effect in triplet excited state was well correlated with the lifetime improvement of the TCzIPN devices.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
