Chediak-Higashi syndrome (CHS) belongs to a group of partial oculocutaneous albinism and immunodeficiency. Five autosomal recessive conditions are recognized in this group, characterized by hypopigmentation of hair, skin and eyes, associated with recurrent infections. Additionally CHS can present coagulopathies, neurological dysfunction and large granules in many cell types. This article is protected by copyright. All rights reserved.

Kah Ni Tan, David Simmons, Catalina Carrasco-Pozo, Karin Borges
Triheptanoin, the triglyceride of heptanoate, is anaplerotic (refills deficient tricarboxylic acid cycle intermediates) via the propionyl-CoA carboxylase (PCC) pathway. It has been shown to be neuroprotective and anticonvulsant in several models of neurological disorders. Here, we investigated the effects of triheptanoin against changes of hippocampal mitochondrial functions, oxidative stress and cell death induced by pilocarpine-induced status epilepticus (SE) in mice. Ten days of triheptanoin pre-treatment did not protect against SE, but it preserved hippocampal mitochondrial functions including state 2, state 3 ADP, state 3 uncoupled respiration, respiration linked to ATP synthesis along with the activities of pyruvate dehydrogenase complex and oxoglutarate dehydrogenase complex 24 h post-SE...

BACKGROUND: Lesions of bullous pemphigoid (BP), an autoimmune subepidermal blistering disease characterized by the presence of tissue-bound and circulating autoantibodies to hemidesmosomal antigens, harbour a mixed inflammatory cellular infiltrate. In various models, neutrophils, eosinophils, mast cells, monocytes as well as B and T cells have been shown to be involved in the pathogenesis of BP. However, their interactions with and effective role in blister formation remains uncertain...

Neurite outgrowth, one of the underlying cellular processes that defines the development and functionality of the mammalian nervous system, is also a sensitive indicator of neuronal cell health. From screening libraries of putative neurotherapeutic compounds to analyzing the millions of environmental pollutants for which we have inadequate neurotoxicity safety data, the large volume of chemical compounds that require evaluation is a major obstacle for manual imaging and analysis methods. In this context, high-content analysis (HCA) has emerged as a sensitive and accurate method for detecting changes in neuronal cell morphology within a format applicable to screening large chemical libraries...

REVIEW
Helen E Scharfman
Hilar mossy cells (MCs) of the dentate gyrus (DG) distinguish the DG from other hippocampal subfields (CA1-3) because there are two glutamatergic cell types in the DG rather than one. Thus, in the DG, the main cell types include glutamatergic granule cells (GCs) and MCs, whereas in CA1-3, the only glutamatergic cell type is the pyramidal cell. In contrast to GCs, MCs are different in morphology, intrinsic electrophysiological properties, afferent input and axonal projections, so their function is likely to be very different from GCs...

BACKGROUND: Several reports on immunoglobulin (Ig)G4-related disease (IgG4-RD) with gastrointestinal involvement (IgG4-related gastrointestinal disease; IgG4-GID) have been published, although this entity has not been fully established clinicopathologically. Thus, we carried out a multicenter survey. METHODS: Patients with possible IgG4-GID who underwent resection were collected. Histologic slides were reevaluated, and eight cases with diffuse lymphoplasmacytic infiltration but without numerous neutrophils, granulations or epithelioid granulomas were further analyzed...

Repeat-associated non-AUG (RAN) translation allows for unconventional initiation at disease-causing repeat expansions. As RAN translation contributes to pathogenesis in multiple neurodegenerative disorders, determining its mechanistic underpinnings may inform therapeutic development. Here we analyze RAN translation at G4C2 repeat expansions that cause C9orf72-associated amyotrophic lateral sclerosis and frontotemporal dementia (C9RAN) and at CGG repeats that cause fragile X-associated tremor/ataxia syndrome...

The increasing use of engineered nanoparticles (NPs) in consumer and industrial products raises concerns about their environmental impacts, but their potential influence on anaerobic ammonium oxidation (anammox) process in wastewater treatment remains unknown. In this study, the response of granule-based anammox reactor to different loads of ZnONPs was investigated. The introduction of 1-5mgL-1 ZnONPs did not affect reactor performance, but 90% of the nitrogen removal capacity was deprived by a shock of 10mgL-1 ZnONPs within 3days...

Sepsis is an organic dysfunction that puts at risk the life of patients suffering this disorder due to an exacerbated immunological response to the infection mediated by the host. Platelets have been largely researched on sepsis owing to its role in Disseminated Intracellular Coagulation (DIC) and because thrombocytopenia is an important clinical feature of these patients. Nevertheless, a great number of evidence shows that platelets have also an important role in immunological response since they have pattern recognition receptors, chemokine receptors and granules with stored soluble mediators...

Platelets store a plethora of different molecules within their granules, modulating numerous pathways, not only in coagulation, but also in angiogenesis, wound healing, and inflammatory diseases. These molecules get rapidly released upon activation and therefore represent an easily accessible indirect marker for platelet activation. Accurate analysis of platelet-derived molecules in the plasma requires appropriate anticoagulation to avoid in vitro activation and subsequent degranulation of platelets, potentially causing artificially high levels and masking biologically relevant differences within translational research studies...

Monica Primacella, Tong Wang, Nuria C Acevedo
Yolk gelation upon 5-week freezing-thawing was studied in 4 recombined yolk systems containing different plasma and granule proportions. Fractionation for mass distribution, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) for protein distribution and rheological properties were explored. Results indicate that both plasma and granule components including LDL, HDL, and α-livetin proteins, contributed to gelation. Protein aggregation was reflected through large mass increase in granule fraction and appearance of a floating LDL layer upon fractionation of gelled yolk systems...

Wound therapy remains a clinical challenge due to the complexity of healing pathology and high demand of achieving functional and aesthetically satisfactory scars. Newly formed blood vessels are essential for tissue repair since they can support cells at the wound site with nutrition and oxygen. In this study, we investigated the effects of Asperosaponin VI (ASA VI) isolated from a traditional Chinese medicine, the root of Dipsacus asper Wall, in promoting angiogenesis, as well as its function in wound therapeutics...

Streptocaulon juventas is a well-known plant that has antimicrobial activity, in vitro antiplasmodial activity, anti-proliferative activity, and antioxidant activity. In this study, we showed experimental evidence that proved that Streptocaulon juventas root ethanolic extract has wound healing activities. First, in a mouse excision wound model, Streptocaulon juventas root ethanolic extract at a dose of 100 mg/kg/day significantly reduced the wound closure time. After 7 days, the wound granulation tissue in mice treated with the extract exhibited a 2...

REVIEW
Edmund T Rolls
A quantitative computational theory of the operation of the hippocampus as an episodic memory system is described. The CA3 system operates as a single attractor or autoassociation network (1) to enable rapid one-trial associations between any spatial location (place in rodents or spatial view in primates) and an object or reward and (2) to provide for completion of the whole memory during recall from any part. The theory is extended to associations between time and object or reward to implement temporal order memory, which is also important in episodic memory...
