[Testicular Tumor in a Patient with Delta Thalassemia Complicated with Hereditary Persistence of Fetal Hemoglobin].

A 30s male was diagnosed as having the left testicular tumor in 2010. He received the anti-neoplastic chemotherapy, and could achieve the complete remission. But, he relapsed with solitary retroperitoneal lymph node swelling in 2012, and he was referred to our hospital.

High-performance solution-processable N-shaped organic semiconducting materials with stabilized crystal phase.

N-shaped organic semiconductors are synthesized via four steps from a readily available starting material. Such semiconductors exhibit preferable ionization potential for p-type operation, thermally stable crystalline phase over 200 °C, and high carrier mobility up to 16 cm(2) V(-1) s(-1) (12.1 cm(2) V(-1) s(-1) on average) with small threshold voltages in solution-crystallized field-effect transistors.

Furan fused V-shaped organic semiconducting materials with high emission and high mobility.

We report a facile synthetic protocol for preparation of dinaphtho[2,3-b:2',3'-d]furan (DNF-V) derivatives. DNF-V derivatives showed high emissive behaviour in solid. A solution-crystallized transistor based on alkylated DNF-V derivatives showed an excellent carrier mobility of up to 1.

V-shaped organic semiconductors with solution processability, high mobility, and high thermal durability.

V-shaped organic semiconductors have been designed and synthesized via a large-scale applicable synthetic route. Solution-crystallized films based on such molecules have demonstrated high-performance transistor properties with maximum mobilities of up to 9.5 cm(2) V(-1) s(-1) as well as pronounced thermal durability of up to 150 °C inherent in the V-shaped cores.

[Evaluation of MRSA rapid detection by real-time PCR directly from positive blood cultures].

Methicillin-resistant Staphylococcus aureus (MRSA), a well-known causative multidrug-resistant pathogen responsible for nosocomial and community-acquired infections, particularly in blood stream infection, often proves difficult and expensive to treat. Despite the need for rapid, accurate MRSA detection for treatment and infection control, conventional testing including culture, have sensitivity and turn-around time (TAT) problems. We evaluated BD GeneOhm MRSA Detection Kit rapid detection performance directly from positive blood culture using real-time PCR.

[Establishment of a microbiology laboratory open 365 days a year and its impact].

The microbiology laboratory of our university hospital aims to provide accurate and rapid microbiological results and useful information for healthcare workers involved in both the treatment of infectious diseases and infection control. For this purpose, we have been running a microbiology laboratory open 365 days a year since 2005. Before starting this laboratory, we formulated both a precise procedural manual and educational program to increase the number of microbiological technologists from 4 to 8 persons and improve their skills.

[Evaluation of the MRSA rapid detection assay (BD GeneOhm MRSA detection kit) by a real-time PCR].

Methicillin-resistant Staphylococcus aureus (MRSA) is well known to be a causative pathogen of skin and soft tissue or blood stream infections, and also to be a nosocomial drug-resistant bacteria in healthcare settings. Although a rapid and accurate detection of MRSA is indispensable for infection control, the conventional tests including culture method have some problems of sensitivity, procedure time, and so on. We evaluated the performance of the rapid detection assay of MRSA (BD GeneOhm MRSA Detection Kit) directly from specimens by a real-time PCR.

[Microbiology laboratory as a base of information sending].

The goal of our microbiology laboratory is to provide an accurate microbiological result and a useful information for every healthcare workers (HCWs). For this purpose, we were trying to do several activities, such as improving the work-flow of microbiology testings, starting 365-day-open microbiology tests, providing some training courses of microbiology and sending many useful informations about infectious diseases and infection control. Before these activities, we needed another 5 microbiology technicians beside 3 technicians and had started the program to educate them.

[Status of the clinical laboratory in the mandatory postgraduate medical training system: from the medical technologists' view (2)].

When the new system of mandatory postgraduate medical training was introduced, we developed a new training program in our clinical laboratory. We will describe this training program in the microbiology laboratory and our experience. We have had 45 min practice of basic microbiology tests, including Gram staining and microscopic examination, for first-grade postgraduate doctors since 2004, and during this practice we emphasize the importance of quality in the clinical specimens collected for cultures and at the same time, explain how to read microbiological test results.
