Arthropods, especially ticks and mosquitoes, are the vectors for a number of parasitic and viral human diseases including malaria, sleeping sickness, Dengue and Zika. Yet arthropods show tremendous individual variation in their capacity to transmit disease. A key factor in this capacity is genetically encoded immune factors that counteract infection by the pathogen. Arthropod-specific pattern recognition receptors and protease cascades detect and respond to infection. Proteins such as antimicrobial peptides, thioester-containing proteins, and transglutaminases effect responses such as lysis, phagocytosis, melanization and agglutination...

Multiple interactions between the immune system and sleep are known, including the effects of microbial challenge on sleep or the effects of sleep loss on facets of the immune response. Cytokines regulate, in part, sleep and immune responses. Here we examine the role of an anti-inflammatory cytokine, interleukin-37 (IL-37) on sleep in a mouse strain that expresses human IL-37b (IL37tg mice). Constitutive expression of the IL-37 gene in the brains of these mice under resting conditions is low; however, upon an inflammatory stimulus, expression increases dramatically...

INTRODUCTION: Sleep generally regulates immune functions in a supportive manner and can affect parameters that are directly involved in the rejection process. STUDY OBJECTIVES: The first objective was to assess whether sleep deprivation (SD) or sleep restriction (SR) affects the allograft rejection process in mice. The second objective was to investigate whether the rejection process itself modulates the sleep pattern of allografted mice. DESIGN: Adult BALB/c and C57BL/6J male mice were used as the donors and recipients, respectively, except for the syngeneic group (ISOTX), which received skin from mice of the same strain (C57BL/6J)...

OBJECTIVES: Health history questionnaires (HHQs) are a set of self-administered questions completed by patients prior to a clinical encounter. Despite widespread use, minimal research has evaluated the content of HHQs used in general internal medicine and family medicine (GIM/FM), integrative medicine, and complementary and alternative medicine (CAM; chiropractic, naturopathic, and Traditional Chinese Medicine [TCM]) clinics. Integrative medicine and CAM claim greater emphasis on well-being than does GIM/FM...

An increasing cohort of haematopoietic cell transplantation (HCT) survivors has raised awareness of long-term and late effects. Updated recommendations for HCT late effects screening were published in 2012 [Majhail et al. Biology of Blood and Marrow Transplantation, 18 (2012):348]. We aimed to assess the clinical efficacy of a dedicated screening clinic to identify problems in HCT survivors using the international guidelines. Clinic letters and test results of the first 59 consecutive patients attending the screening clinic were evaluated...

Adipose tissue (AT) is no longer regarded as an inert lipid storage, but as an important central regulator in energy homeostasis and immunity. Three parasite species are uniquely associated with AT during part of their life cycle: Trypanosoma cruzi, the causative agent of Chagas disease; Trypanosoma brucei, the causative agent of African sleeping sickness; and Plasmodium spp., the causative agents of malaria. In AT, T. cruzi resides inside adipocytes, T. brucei is found in the interstitial spaces between adipocytes, while Plasmodium spp...

Sleep is a profound regulator of cellular immunity, and the curtailment of sleep in present day lifestyle leads to disruption of neuro-immune-endocrine interactions. No therapeutic remedy is yet known for the amelioration of detrimental effects caused by sleep deprivation (SD). The current study was aimed to elucidate the effects of acute SD on immune function and its modulation by water extract from leaves of Withania somnifera (ASH-WEX). Three groups of animals, i.e. Vehicle-Undisturbed sleep (VUD), Vehicle-Sleep deprived (VSD) and ASH-WEX fed sleep deprived (WSD) rats were tested for their anxiety-like behaviour and further used for the study of inflammatory and apoptotic markers expression in piriform cortex and hippocampus regions of the brain...

Chagas disease, caused by Trypanosoma cruzi, although endemic in many parts of Central and South America, is emerging as a global health threat through the potential contamination of blood supplies. Consequently, in the absence of a gold standard assay for the diagnosis of Chagas additional antigens or strategies are needed. A proteomic analysis of the trypomastigote excreted secreted antigens (TESA) associated with exosomal vesicles shed by T. cruzi identified ∼80 parasite proteins; with the majority being trans-sialidases...

Approximately 3500 infants die annually in the United States from sleep-related infant deaths, including sudden infant death syndrome (SIDS), ill-defined deaths, and accidental suffocation and strangulation in bed. After an initial decrease in the 1990s, the overall sleep-related infant death rate has not declined in more recent years. Many of the modifiable and nonmodifiable risk factors for SIDS and other sleep-related infant deaths are strikingly similar. The American Academy of Pediatrics recommends a safe sleep environment that can reduce the risk of all sleep-related infant deaths...

REVIEW
John D Fernstrom
Over the past 50 y, tryptophan has been ingested in amounts well in excess of its dietary requirement. This use is based on extensive findings that ingesting tryptophan increases brain tryptophan concentrations, which stimulates the synthesis and release of the neurotransmitter serotonin, from which it is derived. Such increases in serotonin function may improve mood and sleep. However, tryptophan ingestion has other effects, such as increasing serotonin production in the gut, increasing serotonin concentrations in blood, stimulating the production of the hormone melatonin (a tryptophan metabolite), stimulating tryptophan metabolism via the kynurenine pathway, and possibly stimulating the production of tryptophan metabolites in the gut microbiome...

BACKGROUND AND PURPOSE: Myocarditis is an inflammatory and autoimmune cardiovascular disease that causes dilated myocardiopathy and is responsible of high morbidity and mortality worldwide. Cortistatin is a neuropeptide produced by neurons and cells of immune and vascular systems. Besides its action in locomotor activity and sleep, cortistatin inhibits inflammation in different experimental models of autoimmune diseases. However, its role in inflammatory cardiovascular disorders is unexplored...

Importance: Sudden infant death syndrome remains the leading cause of death in infants aged 1 month to 1 year in the United States. Observations: While its exact cause is unknown, sudden infant death syndrome is believed to be multifactorial, ie, occurs in infants with underlying biological vulnerability who experience an exogenous stressor, such as prone/side sleeping or soft bedding, during a critical developmental period. Much genetic and physiologic evidence points to impaired arousal responses to hypercarbia and hypoxia, which ultimately leads to asphyxia...

The notion that prolonged, intense exercise causes an 'open window' of immunodepression during recovery after exercise is well accepted. Repeated exercise bouts or intensified training without sufficient recovery may increase the risk of illness. However, except for salivary IgA, clear and consistent markers of this immunodepression remain elusive. Exercise increases circulating neutrophil and monocyte counts, and reduces circulating lymphocyte count during recovery. This lymphopenia results from preferential egress of lymphocyte subtypes with potent effector functions (e...

BACKGROUND: Autism spectrum disorder (ASD) is still diagnosed through behavioral observation, due to a lack of laboratory biomarkers, which could greatly aid clinicians in providing earlier and more reliable diagnoses. Metabolomics on human biofluids provides a sensitive tool to identify metabolite profiles potentially usable as biomarkers for ASD. Initial metabolomic studies, analyzing urines and plasma of ASD and control individuals, suggested that autistic patients may share some metabolic abnormalities, despite several inconsistencies stemming from differences in technology, ethnicity, age range, and definition of "control" status...

Gan-Dan-Liang-Yi-Tang (GDLYT) is a Traditional Chinese Medicine that has been historically used for the treatment of insomnia. However, investigations into its pharmacological ingredients and the mechanism underlying its sedative and hypnotic effects remain limited. The present study reported the detailed mechanisms underlying the sedative and hypnotic effects of GDLYT. Kunming mice were administered GDLYT at various sub-hypnotic doses, which underwent sodium pentobarbital treatment test, pentetrazole induced convulsant studies and p-chlorophenylalanine (PCPA) induced insomnia model...
