To adapt to variable environments, humans regulate their behavior by modulating gains in sensory-to-motor processing. In this study, we measured a simple eye movement, the ocular following response (OFR), in monkeys to study the neuronal basis of adaptive motor learning in the visuomotor processing stream. The medial superior temporal (MST) area of the cerebral cortex is a critical site for contextual gain modulation of the OFR. However, the role of MST neurons in adaptive gain modulation of the OFR remains unknown...

Since bacillus Calmette-Guérin (BCG) is an attenuated strain of Mycobacterium bovis, lupus vulgaris (LV) is reported as one of the rare complications after BCG vaccination, correlating with immunosuppression in the lesional skin. In this report, we describe a case of LV arising from the BCG vaccination site 22 years after vaccination. Interestingly, in the present case, granuloma cells were composed of M2-polarized macrophages. Our case might explain the contribution of M2-polarized macrophages to the biology of LV arising from a BCG vaccination site...

About one-half of all Burkitt lymphoma (BL) patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA) subset, defined by an age between 15 and 25-40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein-Barr virus, while the epidemic form strictly follows the pattern of infection by HIV...

Podocalyxin (PC) was first identified as a heavily sialylated transmembrane protein of glomerular podocytes. Recent studies suggest that PC is a remarkable glycoconjugate that acts as a universal glyco-carrier. The glycoforms of PC are responsible for multiple functions in normal tissue, human cancer cells, human embryonic stem cells (hESCs), and human induced pluripotent stem cells (hiPSCs). PC is employed as a major pluripotent marker of hESCs and hiPSCs. Among the general antibodies for human PC, TRA-1-60 and TRA-1-81 recognize the keratan sulfate (KS)-related structures...

BACKGROUND: Trying to simultaneously achieve developmental milestones and cope with a life-threatening disease may place adolescents and young adults (AYAs) at risk for impaired health-related quality of life (HRQoL) later in life. The aim of this study was to examine differences in HRQoL between AYA lymphoma survivors and a normative population and to determine sociodemographic, clinical and long-term symptom-related factors associated with HRQoL. MATERIAL AND METHODS: This study was part of a longitudinal, population-based survey among lymphoma survivors diagnosed between 1999 and 2012...

The possible association between maternal exposure to pyrethroid insecticides (PYRs) during pregnancy and infant development was explored. Levels of exposure to PYRs was assessed by metabolite (3-phenoybenzoic acid, 3-PBA) concentration in maternal spot urine sampled in the first trimester of index pregnancy, and infant development was assessed at 18 months of age using the Kinder Infants Development Scale (KIDS), which is based on a questionnaire to the caretaker. The relationship between KIDS score and maternal urinary 3-PBA levels was examined by a stepwise multiple regression analysis using biological attributes of the mother and infant, breast feeding, and nursing environment as covariates...

Syringomatous carcinoma (SC) is a slow-growing malignant skin tumor that usually affects the face or scalp. An 83-year-old female developed SC on the sole, a rare location. Histopathologically, numerous ducts with few keratinizing cysts were seen in the upper dermis, and cords, strands, and nests with sclerotic stroma were seen in the deep dermis and subcutis. In addition to the perineural and intraneural invasion of the tumor, the tumor cells had also invaded the vessel walls. There was no intravasation of tumor cells or interruption of the endothelium...

BACKGROUND: Persistent tachycardia in pediatric patients after congenital heart surgery further deteriorates their hemodynamic condition, and may become fatal. Therefore, immediate control of the tachycardia is mandatory in these patients. For this purpose, quick-acting, short-acting, titratable intravenous agents are required. However, there are no agents with such characteristics among the drugs approved for control of pediatric arrhythmias in Japan, and thus novel and effective medications for these patients are awaited...

Personality may affect the way adolescents and young adults (AYAs) with cancer report health-related quality of life (HRQoL). Patients aged 15-39 years (n = 165) completed a survey at 12-16 months postdiagnosis. The survey included questions on HRQoL (SF-36), distress Brief Symptom Inventory-18, and personality (NEO-Five-Factor Inventory). Personality traits were not associated with physical HRQoL. The personality trait neuroticism was negatively associated with mental HRQoL (β = -0.37; p < 0...

Although auxin and brassinosteroid (BR) synergistically control various plant responses, the underlying molecular mechanism of auxin-BR crosstalk is not well understood. We previously identified SMOS1, an auxin-regulated APETALA2-type transcription factor (TF), as the causal gene of the small organ size 1 (smos1) mutant that is characterized by a decreased final size of various organs. In this study we identified another smos mutant, smos2, which shows a phenotype indistinguishable from smos1. SMOS2 was identical to the previously reported DWARF AND LOW-TILLERING (DLT), which encodes a GRAS protein involved in BR signaling...

PURPOSE: Little is known about the emotional concerns expressed by adolescent and young adult (AYA) patients in consultations when a diagnosis of cancer is delivered. Here, we investigated the content of such concerns and how health care providers respond to them. METHOD: We audio-recorded nine consultations with AYA cancer patients (ages: 12-25 years) at the time of diagnosis. We have previously identified and coded 135 emotional concerns and the responses to these in the nine consultations using the Verona Coding Definitions of Emotional Sequences (VR-CoDES) framework...

OBJECTIVE: Myxofibrosarcoma has high frequency of local recurrence after surgery. To determine an optimal treatment for recurrent tumors, clinical features of recurrent cases should be characterized. METHODS: We performed a retrospective analysis of 30 patients with recurrent myxofibrosarcoma who underwent surgery between 1999 and 2008. RESULTS: A negative margin after surgery was achieved in only 12 patients (40.0%). The 5-year re-recurrence free-survival rate was 31...
