Amy E Dezern, Michael J Borowitz
Paroxysmal nocturnal hemoglobinuria (PNH) arises as a consequence of the non-malignant clonal expansion of one or more hematopoietic stem cells with an acquired somatic mutation of the PIGA gene.(1) Progeny of affected stem cells are deficient in glycosyl phosphatidylinositol-anchored proteins (GPI-APs). This deficiency is readily detected by flow cytometry. Though this seems straightforward, the clinical utility of this testing requires that the ordering clinician understand not only the characteristics of the test, but also the biology of the underlying disease, and the clinical and laboratory manifestations in the individual patient...

BACKGROUND: Eating late in the day is common, and stress can induce eating. Little is understood about how time of day and stress interact to affect appetite and thereby body weight. These may be particularly important influences in binge eaters, who tend to binge in the evening, and in response to stress. METHOD: Obese participants with (n=16) and without (n=16) Binge Eating Disorder (BED) participated in two identical test protocols beginning either in the morning or the afternoon (AM condition/PM condition), each following an 8 h fast...

Over 100 types of congenital disorders of glycosylation (CDG) have been reported and the number is rapidly increasing. However, each type is very rare and is problematic to diagnose. Mannosyl-oligosaccharide glucosidase (MOGS)-CDG (CDG type IIb) is an extremely rare CDG that has only been reported in three patients from two unrelated families. Using targeted exome sequencing, we identified another patient affected by this condition. This patient had increased serum trisialotransferrin levels. Importantly, a review of the features of all four patients revealed the recognizable clinical hallmarks of MOGS-CDG...

AIM: Gender differences in the current symptomatology of patients with psychotic disorders have previously been described in the literature. However, it has not yet been investigated whether gender differences exist in the very first self-perceived signs or symptoms of illness onset. The aim of this study was to investigate this aspect in at-risk mental state (ARMS) and first-episode psychosis (FEP) patients. METHODS: ARMS and FEP were recruited via the early detection of psychosis (FePsy) clinic Basel, Switzerland...

Upper airway diseases including sinonasal disorders may be caused by exposure to fine particulate matter (≤2.5 μm; PM2.5), as proven by epidemiological studies. PM2.5 is a complex entity whose chemical constituents and physicochemical properties are not confined to a single, independent "particle" but which in this study means a distinctive environmental "toxin." The mechanism whereby PM2.5 induces nasal epithelial barrier dysfunction leading to sinonasal pathology remains unknown. In the present study, human nasal epithelial cells were exposed to non-cytotoxic doses of PM2...

BACKGROUND AND PURPOSE: Histamine modulates several behaviors and physiological functions and its deficiency is associated with neuropsychiatric disorders. Gestational intake of valproic acid (VPA) is linked to Autism Spectrum Disorder (ASD), which is characterized by impaired sociability and stereotypies. VPA effects on the neurochemistry and functional morphology of the histaminergic system in ASD are unclear. Zebrafish are highly social and given the similarities between zebrafish and human neurotransmitter systems, we decided to use zebrafish to study VPA effects on histamine...

Among comorbidity in chronic heart failure (CHF), dysthyroidism represents a relevant problem especially in the ageing CHF patients worldwide. Thyroid greatly affects many cardiovascular activities and its dysfunction may worsen a CHF condition. In particular, hypothyroidism has a relative high prevalence in patients with heart failure and it plays a key role in influencing CHF onset, progression and prognosis. Hyperthyroidism, is less frequent in this clinical context but it necessitates of immediate treatment because of its negative effects on cardiovascular balance...

In the healthy heart, physiological heterogeneities in structure and in electrical and mechanical activity are crucial for normal, efficient excitation and pumping. Alterations of heterogeneity have been linked to arrhythmogenesis in various cardiac disorders such as long QT syndrome (LQTS). This inherited arrhythmia disorder is caused by mutations in different ion channel genes and is characterized by (heterogeneously) prolonged cardiac repolarization and increased risk for ventricular tachycardia, syncope and sudden cardiac death...

Alzheimer's disease (AD) is an age-related neurodegenerative disorder, and the few drugs that are currently available only treat the symptoms. Traditional medicine or phytotherapy has been shown to protect against AD. In our previous studies, Gengnianchun (GNC), a traditional Chinese medicine formula with a prolongevity effect, protected against Aβ-induced cytotoxicity in pheochromocytoma cells (PC-12 cells) and hippocampal cells. Here, we investigated the effects and possible mechanisms by which GNC protected against Aβ toxicity using transgenic Caenorhabditis elegans CL4176...

Indirubins are natural occurring alkaloids extracted from indigo dye-containing plants. Indirubins could inhibit various kinases, and might be used to treat chronic myelocytic leukemia, cancer and neurodegenerative disorders. 7-bromoindirubin-3-oxime (7Bio), an indirubin derivative derived from indirubin-3-oxime, possesses inhibitory effects against cyclin-dependent kinase-5 (CDK5) and glycogen synthase kinase-3β (GSK3β), two pharmacological targets of Alzheimer's disease (AD). In this study, we have discovered that 2...

Glycogen synthase kinases 3 (GSK3) α and β are expressed in the nervous system, and disruption of GSK3 signaling has been implicated in a wide range of neurodevelopmental and psychiatric disorders. Although several studies have established a role of GSK3 signaling in the nervous system, much less is known about isoform-specific functions. Here, we have examined the role of GSK3α and GSK3β in the developing neocortex by performing in utero electroporation with specific small interfering RNAs targeting each isoform...

Disease-associated variants in the human genome are continually being identified using DNA sequencing technologies that are especially effective for Mendelian disorders. Here we sequenced whole genome to high coverage (>30×) of 6 members of a 7-generation family with dwarfism from a consanguineous tribe in Pakistan to determine the causal variant(s). We identified a missense variant rs111033552 (c.2011T>C [p.Ser671Pro]) located in COL10A1 (encodes the alpha chain of type X collagen) as the most likely contributor to the dwarfism...

Individuals perceive the wor(l)d hierarchically. Firsty, the global visual scene is processed by the right hemisphere, and later, the local features are perceived by the left hemisphere. Based on this hierarchical analysis, humans evolved unique communication ability: reading. However, for about 10% of people reading acquisition is extremely difficult, they are affected by a heritable neurodevelopmental disorder called dyslexia. Differences in perceiving the wor(l)d might be one of the causes of reading disabilities...

Parkinson's disease (PD) is a debilitating movement disorder typically associated with the accumulation of intracytoplasmic aggregate prone protein deposits. Over recent years, increasing evidence has led to the suggestion that the mutations underlying certain forms of PD impair autophagy. Autophagy is a degradative pathway that delivers cytoplasmic content to lysosomes for degradation and represents a major route for degradation of aggregated cellular proteins and dysfunctional organelles. Autophagy up-regulation is a promising therapeutic strategy that is being explored for its potential to protect cells against the toxicity of aggregate-prone proteins in neurodegenerative diseases...

OBJECTIVE: While early diagnosis of polycystic ovary syndrome (PCOS) in adolescents may allow for earlier treatment and prevention of chronic disorders, incorrect or premature diagnosis carries risks of unnecessary treatment and psychological distress. There is no consensus concerning which diagnostic criteria to use for adolescents and current criteria vary. The objective of this study was to determine whether using different diagnostic criteria will affect PCOS diagnosis in adolescents...

Life stress increases risk for developing post-traumatic stress disorder (PTSD), and more prominently so in short-allele carriers of the serotonin transporter linked polymorphic region (5-HTTLPR). Serotonin transporter knockout (5-HTT-/-) rats show compromised extinction (recall) of conditioned fear, which might mediate the increased risk for PTSD and reduce the therapeutic efficacy of exposure therapy. Here, we assessed whether acute inescapable stress (IS) differentially affects fear extinction and extinction recall in 5-HTT-/- rats and wildtype controls...

Autoimmune thyroid disease (AITD), including Hashimoto's thyroiditis (HT) and Graves' disease (GD), is the most common autoimmune disorder in the United States, affecting over 20 million people. At the time of diagnosis, both HD and GD are characterized by the accumulation of B and T lymphocytes in the thyroid gland and production of autoantibodies targeting the thyroid, indicating that a breach in tolerance of autoreactive lymphocytes has occurred. However, few studies have sought to understand the underlying pathogenesis of AITD that ultimately leads to production of autoantibodies and loss of thyroid function...

Alzheimer's disease (AD) is a neurodegenerative disorder associated with deficits in cognition and synaptic plasticity. While accumulation of amyloid β (Aβ) and hyper-phosphorylation of tau are parts of the etiology, AD can be caused by a large number of different genetic mutations and other unknown factors. Considering such a heterogeneous nature of AD, it would be desirable to develop treatment strategies that can improve memory irrespective of the individual causes. Reducing the phosphorylation of eukaryotic translation initiation factor 2α (eIF2α) was shown to enhance long-term memory and synaptic plasticity in naïve mice...
