Methylphenidate (MPH) is the front-line psychostimulant medication prescribed for alleviating the symptoms associated with attention deficit hyperactivity disorder (ADHD) in children. Here, we investigated the effects of chronic MPH (2.0mg/kg, twice daily for 15 days) exposure to young rats (20-25days old at start of treatment) on the expression of genes and proteins associated with neuroplasticity, such as activity regulated cytoskeleton-associated protein (Arc), insulin receptor substrate protein 53 (IRSp53), cell division control protein 42 (Cdc42), and actin-related protein 2 (Arp2)...

Background: Major depressive disorder is characterized by structural and functional abnormalities of cortical and limbic brain areas, including a decrease in spine synapse number in the dentate gyrus (DG) of the hippocampus. Recent studies highlighted that both genetic and pharmacological invalidation of the purinergic P2X7 receptor (P2rx7) leads to antidepressant-like phenotype in animal experiments, however, the impact of P2rx7 on depression-related structural changes in the hippocampus is not clarified yet...

Pediatric feeding disorders affect up to 5% of children, causing severe food intake problems that can result in serious medical and developmental outcomes. Behavioral intervention (BI) is effective in extinguishing feeding aversions, and also expert-dependent, time/labor-intensive and not well understood at a neurobiological level. Here we first conducted a double-blind, placebo-controlled trial comparing BI with BI plus d-cycloserine (DCS). DCS is a partial N-methyl-d-aspartate (NMDA) receptor agonist shown to augment extinction therapies in multiple anxiety disorders...

INTRODUCTION: A case of thoracic vertebral osteomyelitis due to Salmonella enteritis (SE) in an immunocompetent patient is reported. This is the third case in the literature of SE thoracic vertebral osteomyelitis, but the first one with this multi-foci presentation and finally fatal outcome due to meningoencephalitis. Further data that makes our case unique are the absence of fever (body temperature: 37.4°C) and gastrointestinal disorders. CASE REPORT: A 57-year-old male patient initially presented with thoracic pain, dyspnea, and knee pain...

REVIEW
Hitoshi Okazawa
PQBP1 (polyglutamine binding protein-1) is the earliest identified molecule among the group of disease-related intrinsically disordered/denatured proteins. PQBP1 interacts with splicing-related factors via the disordered/denatured domain and regulates post-transcriptional gene expression. The mutations cause intellectual disability due to decreased dendritic spines and abnormal expression of synapse molecules in neurons, and microcephaly due to elongated cell cycle time and abnormal expression of cell cycle proteins in neural stem progenitor cells...

Osteogenesis imperfecta (OI) is an inherited bone disorder that causes fractures due to impaired production of collagen type I. In recent years, denosumab, a human monoclonal antibody against receptor activator of nuclear factor κB ligand (RANKL), has become widely used as an anti-osteoclastic agent for osteoporosis. This study investigated osteoporotic cases of OI to examine effects of denosumab on bone fragility. This was a retrospective, consecutive case series that included 3 female patients aged 42, 40, and 14 years, respectively...

Neurofibromatosis Type 1 (NF1) is a neurocutaneous disorder that can have associated spinal abnormalities related to both bone and dural dysplasia. Thoracic meningoceles are one spine anomaly associated with NF1, although they are a fairly uncommon pathology. Surgical techniques to treat these meningoceles, usually undertaken only when the patient is symptomatic, are targeted at decreasing the size of the protrusion and improving lung capacity. Surgical interventions discussed in the literature include shunting the pseudomeningocele, primary repair with laminectomy, thoracoscopic plication, and reinforcement of the closure with cement, muscle, or fascia...

INTRODUCTION: Baropodometrical digital techniques map the pressures exerted on the foot plant during both static and dynamic loadings. The study of the distribution of such pressures makes it possible to evaluate the postural and locomotory biomechanics together with its pathological variations. METHODS: From January 2011 to August 2016 we conducted a cross sectional study in order to diagnose flatfoot and hollowfoot through the baropodometric analysis, and collecting additional information such as gender and the age...

BACKGROUND: Risk for alcohol use disorders (AUDs) in adulthood is linked to alcohol drinking during adolescence, but understanding of the neural and behavioral consequences of alcohol exposure during adolescence remains incomplete. Here, we examined the neurobehavioral impact of adolescent chronic intermittent EtOH (CIE) vapor exposure in mice. METHODS: C57BL/6J-background Thy1-EGFP mice were CIE-exposed during adolescence or adulthood and examined, as adults, for alterations in the density and morphology of dendritic spines in infralimbic (IL) cortex, prelimbic (PL) cortex, and basolateral amygdala (BLA)...

The voltage-gated L-type Ca(2+) channel CaV1.2 is crucial for initiating heartbeat and control of a number of neuronal functions such as neuronal excitability and long-term potentiation. Mutations of CaV1.2 subunits result in serious health problems including arrhythmia, autism spectrum disorders, immunodeficiency, and hypoglycemia. Thus precise control of CaV1.2 surface expression and localization is essential. We previously reported that α-actinin associates and colocalizes with neuronal CaV1.2 channels and that shRNA-mediated depletion of α-actinin significantly reduces localization of endogenous CaV1...

In pelvic organ prolapse (POP), the organs are pushed downward along the lines of gravity, so measurements along this longitudinal body axis are desirable. We propose a universally applicable 3D coordinate system that corrects for changes in pelvic inclination and that allows the localization of any point in the pelvis at rest or under dynamic conditions on magnetic resonance images (MRI) of pelvic floor disorders in a scanner- and software independent manner. The proposed 3D coordinate system called 3D Pelvic Inclination Correction System (PICS) is constructed utilizing four bony landmark points, with the origin set at the inferior pubic point, and three additional points at the sacrum (sacrococcygeal joint) and both ischial spines, which are clearly visible on MRI images...

BACKGROUND: Primary antibody deficiency (PAD) is the most common group of primary immunodeficiency disorders, resulting from different defects in development and function of B cell lineage. Common variable immunodeficiency (CVID) and X-linked agammaglobulinemia (XLA) are two of the major types of PADs. Optimal growth and subsequently bone health could potentially compromise due to the interference of several factors in PAD with childhood onset. In the present study, our aim was to evaluate bone mineral density (BMD) of patients with CVID and XLA...

Mitochondrial dysfunction is associated with several clinical manifestations including diabetes, neurological disorders, renal and hepatic diseases and myopathy. While mitochondrial dysfunction is associated with increased bone resorption and decreased bone formation in mouse models, effects of alterations in mitochondrial function on bone remodelling and mass have not been investigated in humans. We recruited 45 carriers (29 females, 16 males) with the m.3243A > G mutation and healthy controls matched for gender, age, height and menopausal status...

Chronic neck and shoulder pain (CNSP) is a common musculoskeletal disorder in adults, which is linked to hypersensitivity to noxious stimuli. The hormone oxytocin has been implicated as a potential therapeutic for the management of chronic pain disorders, and has been suggested to have sex-specific effects on the salience of threatening stimuli. This study investigated the influence of intranasal oxytocin on the perception of noxious thermal stimuli. Participants were 24 individuals with CNSP lasting >12months (eight women), and 24 age- and sex-matched healthy, pain-free controls...
