BACKGROUND: Hoarding behavior may indicate a clinically and possibly etiologically distinct subtype of obsessive-compulsive disorder (OCD). Empirical evidence supports a relationship between hoarding and emotional over-attachment to objects. However, little is known about the relationship between hoarding and parental attachment in OCD. METHOD: The study sample included 894 adults diagnosed with DSM-IV OCD who had participated in family and genetic studies of OCD...

Using sea urchin embryos, we demonstrate that the MEK/MAPK/ERK cascade is essential for the proper progression of the cell cycle. Activation of a limited fraction of MAPK/ERK is required between S-phase and M-phase. Neither DNA replication nor CDK1 activation are impacted by the inhibition of this small active MAPK/ERK fraction. Nonetheless, the chromatin and spindle organisations are profoundly altered. Early morphological disorders induced by the absence of MAPK/ERK activation are correlated with an important inhibition of global protein synthesis and modification in the cyclin B accumulation profile...

BACKGROUND: Obsessive-compulsive disorder (OCD) is a chronic neurodevelopmental disorder that affects up to 3% of the general population. Although epigenetic mechanisms play a role in neurodevelopment disorders, epigenetic pathways associated with OCD have rarely been investigated. Oxytocin is a neuropeptide involved in neurobehavioral functions. Oxytocin has been shown to be associated with the regulation of complex socio-cognitive processes such as attachment, social exploration, and social recognition, as well as anxiety and other stress-related behaviors...

OBJECTIVE Arteriovenous malformation (AVM) is an intracranial vascular disorder. Gamma Knife radiosurgery (GKRS) is used in conjunction with intraarterial embolization to eradicate the nidus of AVMs. Clinical results indicate that patients with prior embolization tend to gain less benefit from GKRS. The authors hypothesized that this was partly caused by dosimetric deficiency. The actual dose delivered to the target may be smaller than the intended dose because of increased photon attenuation by high-density embolic materials...

BACKGROUND Alzheimer disease (AD) primarily affects cognition. A variety of visual disorders was established in AD. Fechner illusory colors are produced by a rotating disk with a black and white pattern. The purpose of our research was to explore the perception of illusory colors in AD. MATERIAL AND METHODS W recruited 40 AD patients (MMSE ≥14) and 40 normal controls (CG group) matched by age, education, gender in this prospective, cross-sectional, case-control study. An achromatic Benham's disk attached to a device to control the speed and direction of rotation was used to produce illusory colors...

Although several studies have highlighted the relationship between attachment states of mind and personality disorders, their findings have not been consistent, possibly due to the application of the traditional taxonomic classification model of attachment. A more recently developed dimensional classification of attachment representations, including more specific aspects of trauma-related representations, may have advantages. In this study, we compare specific associations and predictive power of the categorical attachment and dimensional models applied to 230 Adult Attachment Interview transcripts obtained from personality disordered and nonpsychiatric subjects...

OBJECTIVES: Borderline personality disorder (BPD) is characterized by emotional instability, interpersonal dysfunction, and other features that typically develop before a background of insecure attachment and traumatic experiences. Dialectical behaviour therapy (DBT) has proven highly effective in reducing self-harm and improving emotion regulation, whereby problems concerning social cognition, which are also characteristic of BPD, may need additional approaches such as mentalization-based treatment (MBT)...

DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) Reactive Attachment Disorder (RAD) and Disinhibited Social Engagement Disorder (DSED) are rare disorders sharing social difficulties with autism. The DSM-5 and ICD-10 (International Classification of Diseases, 10th revsion) state that RAD/DSED should not be diagnosed in children with autism. The purpose of our study is to determine whether children can meet criteria for both autism and RAD/DSED and to identify specific symptoms discriminating the disorders...

Most neurodevelopmental disorders are defined by their clinical symptoms and many disorders share common features. Recently there has been an increase in the number of children diagnosed with autism spectrum disorder, although concerns have been raised about the accuracy of the reported prevalence rates. This article reviews the essential features of autism spectrum disorder and describes other conditions that may include similar symptoms that may be misdiagnosed as autism spectrum disorder (primary communication disorders, anxiety disorders, attachment disorders, intellectual disability, vision and hearing impairment, and normal variations)...

Staphylococcus epidermidis is one of the primary bacterial species responsible for healthcare-associated infections. The most significant virulence factor for S. epidermidis is its ability to form a biofilm, which renders the bacteria highly resistant to host immune responses and antibiotic action. Intercellular adhesion within the biofilm is mediated by the accumulation-associated protein (Aap), a cell wall-anchored protein that self-assembles in a zinc-dependent manner. The C-terminal portion of Aap contains a proline/glycine-rich, 135 amino acid-long region that has not yet been characterized...

Lysosomal storage disorders (LSDs) are inherited diseases characterized by lysosomal dysfunction and often showing a neurodegenerative course. There is no cure to treat the central nervous system in LSDs. Moreover, the mechanisms driving neuronal degeneration in these pathological conditions remain largely unknown. By studying mouse models of LSDs, we found that neurodegeneration develops progressively with profound alterations in presynaptic structure and function. In these models, impaired lysosomal activity causes massive perikaryal accumulation of insoluble α-synuclein and increased proteasomal degradation of cysteine string protein α (CSPα)...

OBJECTIVES: The aversive, long-term toll of war captivity and fathers' combat-induced posttraumatic stress disorder (PTSD) on adult offspring's secondary traumatization (ST) has been recently exemplified. However, the study of potential mechanisms of the intergenerational transmission of trauma to offspring is still lacking. This prospective study aimed to assess the role of fathers' PTSD symptoms (PTSS), paternal parenting, and adult offspring's attachment insecurities in adult offspring's PTSS...

Preterm birth remains a major contributor to infant mortality and morbidity including neurodevelopmental delay and childhood disability. Mothers experiencing a preterm birth are at risk for maternal mental health issues, inclusive of depression and posttraumatic stress disorder (PTSD), which may affect mother-infant attachment and infant development. Depression and PTSD, frequently comorbid, following preterm birth and relationships between these symptoms, maternal-infant attachment, and infant development are reviewed...

PGAP2 (Post-GPI Attachment to Proteins 2) gene is involved in lipid remodeling steps of Glycosylphosphatidylinositol (GPI)-anchor maturation. At the surface of the cell this gene is required for proper expression of GPI-anchored proteins. Hyperphosphatasia with mental retardation syndrome-3 is an autosomal recessive disorder usually characterized by severe mental retardation. Mutations in the PGAP2 gene cause hyperphosphatasia mental retardation syndrome-3. We have identified a large consanguineous family from Saudi origin segregating developmental delay, intellectual disability, epilepsy and microcephaly...

Research on mental health following disasters has led to the identification of many individual protective and risk factors for postdisaster mental health. However, there is little understanding of the exact influence that disasters have on the functioning of intimate relationships. Especially relevant are attachment styles, which are likely to play an important role in the provision and perception of social support between partners, and subsequent mental health outcomes. Heterosexual couples (N = 127) affected by the 2009 Victorian "Black Saturday" Bushfires in southeastern Australia were surveyed for disaster experiences, posttraumatic stress disorder (PTSD) symptoms, depression, and attachment style between May 2012 and January 2013, approximately 3 years after the disaster...

Fanconi anemia (FA) is an autosomal-recessive disorder associated with hematopoietic failure and it is a candidate for hematopoietic stem cell (HSC)-directed gene therapy. However, the characteristically reduced HSC numbers found in FA patients, their ineffective mobilization from the marrow, and re-oxygenation damage during ex vivo manipulation have precluded clinical success using conventional in vitro approaches. We previously demonstrated that lentiviral vector (LV) particles reversibly attach to the cell surface where they gain protection from serum complement neutralization...

Carla Smith Stover, Brooks Keeshin
By definition, the Diagnostic and Statistical Manual (DSM) diagnosis of posttraumatic stress disorder (PTSD) requires exposure to a traumatic event. Yet, the DSM diagnostic requirements for children and adolescents for PTSD may fail to capture traumatized youth with significant distress and functional impairment. Many important studies have utilized PTSD diagnosis as a mechanism for grouping individuals for comparative studies examining brain functioning, neuroendocrinology, genetics, attachment, and cognition; however, focusing only on those with the diagnosis of PTSD can miss the spectrum of symptoms and difficulties that impact children who experience trauma and subsequent impairment...

: In early adolescence, Hispanics self-report higher drug use rates compared to White and African American peers. Among adolescent users, heavy users have more negative behavioral and health consequences. The purpose of this cross-sectional study is to examine whether psychiatric symptoms, parental attachment, and reasons for use predict heavy alcohol and illicit drug use (more than 10 times in the past three months) among Hispanic adolescents. METHODS: This study examines baseline data from a study evaluating a family based substance abuse treatment program for Hispanic adolescents...
