Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for diagnosis and intervention in patients with biliopancreatic disorders. However, ERCP in patients with surgically altered anatomy (SAA) is considered more difficult than in patients with normal anatomy. Since the introduction of balloon enteroscopes for patients with small intestine disorders, single-balloon enteroscopes (SBEs) and double-balloon enteroscopes (DBEs) have also been used for biliopancreatic diseases in patients with SAA. Nevertheless, the use of conventional SBEs and DBEs is limited, as a balloon enteroscope has a working length of 200 cm and a narrow working channel with a diameter of 2.8 mm; therefore, few ERCP accessories are available for use. A short-type SBE with a working length of 152 cm and a working channel of 3.2 mm in diameter, and a short-type DBE with a working length of 155 cm and a working channel of 3.2 mm were introduced to solve these difficulties. Favorable outcomes of these devices have recently been reported. Moreover, studies have reported several tips to achieve procedural success and factors affecting procedure failure. Difficult cases necessitate alternative techniques, such as percutaneous transhepatic biliary drainage and endoscopic ultrasound-guided biliary drainage.

Background/Aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the diagnostic yield and puncturing ability of EUS-TA using 22-gauge cobalt-chromium (CO-Cr) needles with those of stainless-steel Franseen needles in patients with solid pancreatic lesions. Methods: Outcomes were compared between the 22-gauge Co-Cr Franseen needle (December 2019 to November 2020; group C) and stainless-steel needle (November 2020 to May 2022; group S). Results: A total of 155 patients (group C, 75; group S, 80) were eligible. The diagnostic accuracy was 92.0% in group C and 96.3% in group S with no significant intergroup differences (p=0.32). The rate of change in the operator (from training fellows to experts) was 20.0% (15/75) in group C and 7.5% (6/80) in group S. Stainless-steel Franseen needles showed less inter-operator difference than Co-Cr needles (p=0.03). Conclusions: Both Co-Cr and stainless-steel Franseen needles showed high diagnostic ability. Stainless-steel Franseen needles are soft and flexible; therefore, the range of puncture angles can be widely adjusted, making them suitable for training fellows to complete the procedure.

[OBJECTIVES] To understand the condition of athletes engaged in daily sports activities, it is important to investigate the pain that many such athletes can experience as well as the pain that can be an initial symptom of injury. Although handball is a contact sport associated with frequent injuries, the actual nature of pain symptoms that develop has not been sufficiently studied, and the relationship between pain occurrence and athletes’ daily changing physical load remains unclear. This study aimed to clarify the nature of pain symptoms in handball players and examine the relationship between pain occurrence and physical load. [METHODS] This study involved a 12-month daily assessment of pain symptoms and physical load involving 11 university female handball players. Pain was examined in terms of body region and a pain severity score using a pain questionnaire, and physical load on handball was assessed based on playing hours, types of matches and training recorded by a video camera. [RESULTS] The total number of pains was 1698, and the pain incidence rate was 288.1 pains per 1000 player hours. In terms of body regions, the ankle (18.3%) was the most common, followed by the lower back (13.3%), foot (12.8%), Achilles tendon (9.2%), and thigh (8.9%). With regard to the relationship between pain and physical load, significant moderate or weak correlations were observed between handball (rs=0.657), training (rs=0.626), and on-court training (rs=0.591) and overall pain occurrences. In terms of body regions, the ankle and thigh, significant moderate or weak correlations were observed with respect to all categories in on-court training. [CONCLUSIONS] We found that pain occur frequently and athletes continue to compete in games despite experiencing pain. In addition, pain occurrence was related to physical load, indicating that the type of physical load depends on the body region.

This surveillance research drafted a conservation plan of regional green spaces, on a metropolitan area level, geared toward the Minuma Tanbo area of 1260 ha, located in Saitama City, in the suburbs of Tokyo. It was an effective method, applied to an area where Japan's current issues on regional green space were epitomized, as it formed symposiums consisting of various personnel, and the opinions of the citizen had been reflected.

The National Bio Resource Project-Rat (NBRP-Rat) comprises the largest bank of laboratory rat (Rattus norvegicus) strains in the world. Its main focus is to develop infrastructure that will facilitate the systematic collection, preservation, and provision of rat strains. To breed effectively more than 180 rat strains in living stock, we establish the genetic control system in which a systematic set of genetic diagnoses and genetic monitoring are included. Genetic monitoring is performed by using 20 polymorphic markers. Monitoring is carried out when a living animal stock is re-established by using cryopreserved embryos or sperm or when a rat strain is first introduced to the NBRP-Rat by a depositor. Additional monitoring is then carried out on each strain every two years. Genetic diagnosis is performed largely by employing the Amp-FTA method. Protocols which detail how to perform a genetic diagnosis of 11 transgenes and 24 mutations have been made. Among the mutations, nine can be detected by simple gel electrophoresis of the PCR products, 11 by restriction enzyme treatment of the PCR products, and four by direct PCR product sequencing. Using this genetic control system, the NBRP-Rat can guarantee the genetic quality of its rat strains.
