Idiopathic thrombocytopenic purpura (ITP) is the condition of having an abnormally low platelet count with an unknown cause. Acute subdural hematomas (ASDHs) usually develop in trauma patients and often involve a high bleeding tendency. However, ITP patients rarely have a large ASDH, and when a traditional decompressive craniectomy is performed on patients with coagulopathy, the mortality rate is higher because of the greater bleeding risk. We report the case of an ITP patient with a large ASDH who treated with a burr-hole trephination and irrigation and who was discharged without any neurological deficit.

Background: Evaluation of nutritional status is essential clinical procedures for managing renal transplantation patients, especially in status of chronic kidney disease (CKD). However, no standard method for assessing the nutritional status in renal transplantation patients exists. Onodera`s Prognostic Nutritional Index (OPNI) is a method that considers serum albumin level and total lymphocyte count. This simple method may involve common measures and can be applied rapidly in a large number of patients. Validation of OPNI has been performed for patients with end-stage liver disease, active tuberculosis, and gastrointestinal malignancies. Methods: We examined the OPNI scores of 184 renal transplantation patients (50.2 ± 11.3 years; 115 men and 69 women). The OPNI is calculated based on the serum albumin level and total lymphocyte count and uses the following equation: OPNI = 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (/mL). Logistic regression analysis was performed for predicting malnutrition in renal transplantation patients. Results: The average OPNI value was 48.9 ± 7.1, and OPNI values were normally distributed. According to logistic regression for predicting malnutrition, male, total lymphocyte count and chronic kidney disease predicted malnutrition. Conclusions: These results suggest that OPNI may be a signifi cant nutritional marker in renal transplantation patients. The simple OPNI method is a clinically useful marker for the assessment of nutritional status in renal transplantation patients.

Red/green/blue selective phototransistors with a hybrid structure of quantum-dots and an oxide semiconductor

Yu, Jiin,Kim, Byung Jun,Park, Sungho,Han, Il Ki,Kang, Seong Jun Institute of Pure and Applied Physics 2018 Japanese Journal of Applied Physics Vol. No.

<P>Color-selective phototransistors have been developed using a hybrid film of quantum-dots (QDs) and an oxide semiconductor. The zinc oxide (ZnO) phototransistor with QDs with a 2.96 eV band gap showed a photocurrent when illuminated by 450nm light. The device with QDs with a 2.28 eV band gap started to show a photocurrent under 520 nm light, and the device with QDs with a 1.95 eV band gap showed a photocurrent under light with a wavelength of 635 nm. The photocurrent with low-energy photons, such as visible light, originated when small band-gap QDs absorbed and converted visible light into photoelectrons, and the transparent wide band-gap ZnO supplied a conductive channel in the conduction band to allow the photocurrent to flow through the device. Based on those results, we developed a color-selective phototransistor that can separate red, green, and blue light using a hybrid structure of ZnO and multilayer QDs. The device showed photoresponsivity values of 0.032, 0.053, and 0.26 mA/W to red, green, and blue light, respectively, which are different enough to distinguish the color of the visible light. Therefore, we fabricated and characterized a photogating inverter to convert the color of visible light into an electrical voltage signal. Our results show that the hybrid film of ZnO and QDs could be a feasible way to develop a highly transparent, full-color image sensor. (c) 2018 The Japan Society of Applied Physics</P>

Photomodulation of InGaZnO thin film transistors with interfacial silver nanoparticles

Yu, Jiin,Cho, Jae Eun,Lee, Hyeon-Mo,Park, Jin-Seong,Kang, Seong Jun IOP Publishing 2016 Japanese journal of applied physics Vol.55 No.11

<P>Silver nanoparticles (Ag NPs) were inserted between indium gallium zinc oxide (IGZO) and a gate insulator to enhance the generation of plasmonic photocurrent with the illumination of visible light. Ag NPs were formed on a silicon dioxide gate insulator using a thermal evaporator and a post-annealing process. Then, an amorphous IGZO active channel layer was deposited on the Ag NPs using a sputter system. The prepared Ag NPs effectively absorbed a wide wavelength range of visible light due to plasmon effects. The IGZO thin film transistors (TFTs) with interfacial Ag NPs showed a large photocurrent due to the strong coupling between localized plasmons and electrical carriers in the active channel region of the TFTs. The prepared device showed good modulation behavior under visible light even though IGZO has a wide band gap. The results indicate that interfacial Ag NPs enabled the photomodulation of IGZO TFTs when exposed to a periodic signal of low-energy visible light. This work demonstrates a useful way to develop visible-light phototransistors based on a wide band gap semiconductor and plasmonic Ag NPs. (C) 2016 The Japan Society of Applied Physics</P>
