The objective of this study was to investigate clinical manifestations of lower extremity edema (LEE) in endometrial cancer Medical records for LEE and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were evaluated in 177 patients with endometrial cancer Patients had a median age of 53 years. Sixty-seven patients (37.9%) had past (9 patients, 13.4%) and/or current patient-reported LEE (58 patients, 86.6%). Symptoms reported on the GCLQ in over 20% of respondents were swelling, numbness, aching , and heaviness. GCLQ total symptoms score was significantly higher in patients with current LEE. Most of the LEE (43/67, 64.2%) developed within 12 months after surgery and LEE lasted more than 6 months in most patients (56/59, 94.9%) Prospective clinical trials are needed to know the clinical significance, impact on quality of life, and preventive strategy of LEE in patients with endometrial cancer

<P><B>Abstract</B></P> <P>SrTiO<SUB>3</SUB> (STO) thin films, grown by atomic layer deposition (ALD), were studied for capacitors in dynamic random access memory. The STO ALD process consisted of two steps: the growth of seed layer followed by a rapid thermal annealing (RTA) process at 650°C to crystallize it, and the deposition of the main layer on top of the seed layer at 370°C to induce the in-situ crystallization. During single cooling process after the RTA of the seed layer, voids and nano-cracks were formed due to the thermal expansion mismatch between STO film and Si substrate. This problem was well mitigated by adopting the stepwise cooling process, wherein the holding time of 30s at 500, 350, and 200°C suppressed the defect formation in the seed layer. Therefore, the main layer grown on that seed layer showed an improved microstructure with a high bulk dielectric constant of 135. However, the increase in total annealing time degraded the interface quality between the STO and the bottom electrode, which finally worsened the insulating property. As a result, the minimum equivalent oxide thicknesses with low leakage current densities (<10<SUP>−7</SUP> A/cm<SUP>2</SUP> at 0.8V) for the single and stepwise cooling processes were 0.39nm and 0.46nm, respectively.</P> <P><B>Highlights</B></P> <P> <UL> <LI> SrTiO<SUB>3</SUB> films with high dielectric constant were grown by atomic layer deposition. </LI> <LI> Two kinds of cooling processes after crystallization annealing were examined. </LI> <LI> Microstructure was improved by adopting the stepwise cooling process. </LI> <LI> Bulk dielectric constant was improved by adopting the stepwise cooling process. </LI> <LI> Amorphous STO was grown on the void region of STO seed layer. </LI> </UL> </P>

<P>Organic acids have long been known for their beneficial effects on growth performance in domestic animals. However, their impact on immune responses against viral antigens in chickens is unclear. The present study aimed to investigate immunological parameters in broilers immunized with a H9N2 vaccine and/or fed a diet containing organic acids (citric, formic, and lactic acids). We allotted 1-day-old broilers into 4 groups: control (C), fed a diet supplemented with organic acids (O), administered a H9N2 vaccine (V), and fed a diet supplemented with organic acids and administered a H9N2 vaccine (OV). Blood and spleen samples were taken at 2, 7 and 14 d post vaccination (DPV). At 14 DPV, total and H9N2-specific IgG levels were significantly lower in the OV group than in the V group. However, it was intriguing to observe that at 2 DPV, the percentage of CD4(+) CD25(+) T cells was significantly higher in the OV group than in the other groups, indicating the potential induction of regulatory T cells by organic acids. In contrast, at 2 DPV, the percentage of CD4(+) CD28(+) T cells were significantly lower in the OV group than in the other groups, suggesting that CD28 molecules are down-regulated by the treatment. The expression of CD28 on CD4(+) T cells, up-regulated by the stimulation with phorbol 12-myristate 13-acetate (PMA) and ionomycin (Iono), was inhibited upon organic acid treatment in OV group. In addition, the proliferation of lymphocytes, stimulated with formalin-inactivated H9N2, was significantly higher in the V group than in the OV group. Alpha 1-acid glycoprotein (AGP) production was significantly lower in the OV group than in the V group, suggesting that the organic acids inhibited the inflammation caused by the vaccination. Overall, induction of regulatory CD4(+) CD25(+) T cells, coinciding with the decrease of H9N2-specific antibodies, was observed in broilers fed organic acids.</P>

Objective To assess the efficacy of high-frequency repetitive transcranial magnetic stimulation (rTMS) on balance function in patients with chronic stroke.Methods Thirty participants with chronic stroke were enrolled in this study. High frequency (10 Hz) rTMS was delivered with butterfly-coil on trunk motor spot. Each patient received both real and sham rTMS in a random sequence. The rTMS cycles (real or sham) were composed of 10 sessions each, administered over two weeks, and separated by a 4-week washout period. Balance function was measured by Berg Balance Scale and computerized dynamic posturography to determine the effect of rTMS before and one day after the end of each treatment period, as well as at a 1-month follow-up.Results The balance function was significantly improved after high frequency rTMS as compared with that after sham rTMS (p<0.05). There was no serious adverse effect in patients during the treatment period. Conclusion In the chronic stroke patients, high frequency rTMS to the trunk motor area seems to be a helpful way to improve balance function without any specific adverse effects. Further studies are needed to identify the underlying mechanism and generate a detailed protocol.

<P>The order-order transition temperature (T(OOT)) in blends of poly(styrene-b-isoprene-b-styrene) (S-I-S) triblock copolymer and polyisoprene (PI) homopolymer was investigated by using synchrotron small-angle X-ray scattering (SAXS). Pure triblock copolymer undergoes an order-order transition (OOT) from hexagonally ordered cylinder (HEX) to body centered cubic (BCC) phases. In order to investigate the effect of the molecular weight of the added homopolymer on T(OOT) of the triblock copolymer, various low-molecular-weight PI homopolymers were studied. The results revealed that T(OOT) was affected by the PI molecular weight. T(OOT) was reduced for blends having low-molecular-weight PI.</P>
Intelligent classification methods of grain kernels using computer vision analysis
Lee, Choon Young,Yan, Lei,Wang, Tianfeng,Lee, Sang Ryong,Park, Cheol Woo IOP Pub 2011 Measurement Science and Technology Vol.22 No.6
<P>In this paper, a digital image analysis method was developed to classify seven kinds of individual grain kernels (common rice, glutinous rice, rough rice, brown rice, buckwheat, common barley and glutinous barley) widely planted in Korea. A total of 2800 color images of individual grain kernels were acquired as a data set. Seven color and ten morphological features were extracted and processed by linear discriminant analysis to improve the efficiency of the identification process. The output features from linear discriminant analysis were used as input to the four-layer back-propagation network to classify different grain kernel varieties. The data set was divided into three groups: 70% for training, 20% for validation, and 10% for testing the network. The classification experimental results show that the proposed method is able to classify the grain kernel varieties efficiently.</P>
