AIM: Extra-ampullary duodenal adenoma (EADA) is a rare condition with poorly described clinicopathological details. In this study, we aimed to clinicopathologically characterize EADA. METHODS AND RESULTS: We performed a retrospective review of 44 serial cases of EADA. Each EADA was categorized as either gastric-type (n=5) or intestinal-type (n=39). All gastric-type adenomas were located in the first portion of the duodenum and exhibited a pedunculated shape. Gastric-type adenomas were classified into two subtypes: a pyloric gland type and a foveolar type...

In the central nervous system, endothelial cells (ECs) and pericytes (PCs) of blood vessel walls cooperatively form a physical and chemical barrier to maintain neural homeostasis. However, in diabetic retinopathy (DR), the loss of PCs from vessel walls is assumed to cause breakdown of the blood-retina barrier (BRB) and subsequent vision-threatening vascular dysfunctions. Nonetheless, the lack of adequate DR animal models has precluded disease understanding and drug discovery. Here, by using an anti-PDGFRβ antibody, we show that transient inhibition of the PC recruitment to developing retinal vessels sustained EC-PC dissociations and BRB breakdown in adult mouse retinas, reproducing characteristic features of DR such as hyperpermeability, hypoperfusion, and neoangiogenesis...

Corticospinal excitation is mediated by polysynaptic pathways in several vertebrates, including dexterous monkeys. However, indirect non-monosynaptic excitation has not been clearly observed following transcranial electrical stimulation (TES) or cervicomedullary stimulation (CMS) in humans. The present study evaluated indirect motor pathways in normal human subjects by recording the activities of single motor units (MUs) in the biceps brachii (BB) muscle. The pyramidal tract was stimulated with weak TES, CMS, and transcranial magnetic stimulation (TMS) contralateral to the recording side...

Monoclonal immunoglobulin G (IgG) is a multi-domain protein. It has been reported that the conformational and colloidal stabilities of each domain are different and it is predicted that limited domains participate in IgG aggregation. In contrast, the influence of inter-domain interactions on IgG aggregation remains unclear. The fragment crystallizable (Fc) region is also a multi-domain protein consisting of two sets of CH2 and CH3 domains. Here, we have analyzed the conformational change and aggregate size of an aglycosylated Fc region induced by both acid- and salt-stresses, and have elucidated the influence of inter-domain interactions between CH2 and CH3 domains on the conformational and colloidal stabilities of the aglycosylated Fc region...

Pancreatic cancer is highly malignant, characterized by aggressive proliferation, invasion, and metastasis. α-Bisabolol is an oily sesquiterpene alcohol derived from a variety of plants. We previously demonstrated that α-bisabolol is a potential therapeutic agent for pancreatic cancer. The aim of this study was to develop α-bisabolol derivatives which are more potent than the parent compound and may be clinically useful against pancreatic cancer. First, 22 derivatives of α-bisabolol were designed and synthesized...

: Presence of underlying metatarsus deformity is known to negatively affect the outcome of hallux valgus corrective surgery. Yet there are many other factors that also affect final outcomes. In order to address the potential relationships between variables, we attempted to evaluate the association of metatarsus adductus with surgical outcomes, independent of other common factors used in evaluation of hallux valgus deformity. We enrolled 154 patients who had undergone hallux valgus corrective surgery and recorded their pre- and postoperative intermetatarsal (IM12) and hallux valgus (HVA) angles, preoperative Engel's angle, and type of hallux valgus procedure...

Over the past decades, scientists endeavored to comprehend oxidative stress in poultry spermatozoa and its relationship with fertilizing ability, lipid peroxidation (LPO), free-radical scavenging systems, and antioxidant therapy. Although considerable progress has been made, further improvement is needed in understanding how specific reactive oxygen species (ROS) and malondialdehyde (MDA, a toxic byproduct of LPO) disrupt organelles in avian spermatozoon. Hence, this study examined functional changes in chicken spermatozoa after incubation with different ROS, and their implications for the fertility...

It is well known that intersigmoid hernia (ISH) is a rare condition. Here we describe our experience of laparoscopic surgery for small-bowel obstruction (SBO) due to ISH after sufficient decompression involving long-tube insertion.A 45-year-old woman with no history of abdominal surgery visited our hospital with epigastric pain. She was diagnosed as having SBO and underwent long-tube insertion as conservative therapy. However, her symptoms did not improve. Gastrografin contrast enema via the long-tube demonstrated a beak sign in the lower left abdomen and CT showed incarcerated small bowel was successively covered by sigmoid mesocolon, suggesting that the SBO was due to ISH, and she underwent laparoscopic surgery after sufficient decompression of the dilated small bowel...

Pneumococcal vaccines have reduced the incidences of Streptococcus pneumoniae infections among children and adults, but a relative increase in the prevalence of non-vaccine serotypes has been reported. To follow the changing epidemiology of pneumococcal diseases, capsular serotyping and antimicrobial susceptibility testing was performed on 534 pneumococcal isolates obtained from a hospital in Japan after routine immunization was launched, between October 2014 and May 2016. Serotype distributions and antimicrobial susceptibilities were evaluated among the total patient population, and were compared by age and sample groups and by serotype group, respectively...

INTRODUCTION: Laparoendoscopic single-site surgery is a recently innovated urologic surgical procedure. Transumbilical laparoendoscopic single-site adrenalectomy (LESS-A) is technically safe and feasible in patients with benign adrenal tumors. To improve patient counseling and informed consent, we evaluated patient-reported postoperative pain, body image, and cosmetic satisfaction after transumbilical LESS-A. METHODS: We reviewed 24 patients who underwent transumbilical LESS-A and assessed their operative and esthetic outcomes and incisional pain...

This study proposes an automatic classification method based on machine learning in contrast-enhanced ultrasonography (CEUS) of focal liver lesions (FLLs) using the contrast agent Sonazoid R ⃝ . This method yields spatial and temporal features in the arterial phase, portal phase, and post-vascular phase, as well as max-hold images. The lesions are classified as benign or malignant and again as benign, hepatocellular carcinoma (HCC), or metastatic liver tumor using support vector machines (SVM) with a combination of selected optimal features...

A 75-year-old man admitted for left lateral abdominal pain was found to have advanced poorly differentiated gastric adenocarcinoma with abdominal para-aortic and Virchow's lymph node metastases, which was diagnosed to be clinical Stage IV (T3N3H0M1[LYM]). As curative surgery was not deemed possible, we started chemotherapy administration using S-1 (120mg/day)administered orally for 3 weeks and cisplatin(CDDP 100mg/body)administered intravenously on day 8. After 6 courses of chemotherapy, a CT scan showed that all lymph nodes metastases had disappeared, resulting in downstaging to clinical Stage II (T3[SE]N0H0P0M0)...
