Recent evidence suggests that interval timing (the judgment of durations lasting from approximately 500 ms. to a few minutes) is closely coupled to the action control system. We used surface electromyography (EMG) and motion capture technology to explore the emergence of this coupling in 4-, 6-, and 8-month-olds. We engaged infants in an active and socially relevant arm-raising task with seven cycles and response period. In one condition, cycles were slow (every 4 s); in another, they were fast (every 2 s)...

The tolerogenic hepatic microenvironment impedes clearance of viral infections but is an advantage in viral vector gene transfer, which often results in immune tolerance induction to transgene products. Although the underlying tolerance mechanism has been extensively studied, our understanding of antigen presentation to transgene product-specific CD4(+) T cells remains limited. To address this, we administered hepatotropic adeno-associated virus (AAV8) vector expressing cytoplasmic ovalbumin (OVA) into wt mice followed by adoptive transfer of transgenic OVA-specific T cells...

STUDY QUESTION: Has there been any influence of the Zika virus (ZIKV) outbreak on the sales of contraceptive methods in Brazil? SUMMARY ANSWER: Contraceptive sales in the 24 months of evaluation showed little variation and no significant change has been observed since the ZIKV outbreak. WHAT IS KNOWN ALREADY: Transmission of ZIKV is primarily by Aedes aegypti mosquitoes; however, sexual transmission has also been described. The association of several birth defects and the ZIKV infection during pregnancy has been established, and it was estimated in Bahia, Brazil that the infection rate could range from 10% to 80%...

Necroptosis is a caspase 8-independent cell death that requires co-activation of receptor-interacting protein (RIP) 1 and RIP 3 kinases. The necrosome is a complex consisting of RIP1, RIP3 and Fas-associated protein with death domain (FADD) leading to activation of the pseudokinase mixed lineage kinase like (MLKL) followed by a rapid plasma membrane rupture and inflammatory response through the release of damage-associated molecular patterns (DAMPs) and cytokines. The necrosome has been shown to be relevant in multiple tumor types, including pancreatic adenocarcinoma, melanoma and several hematological malignancies...

The significant role of the immune system in cancer treatment has given rise to an emerging field of study within oncology, and one that is attracting increasing attention from researchers. Immunotherapy has demonstrated that the immune system is crucial in the fight against cancer. This challenge has led researchers to analyze whether the immune influencing capacity of immunonutrition may aid in improving immune status, modulate the acquired immune response, decrease the treatment toxicity and improve patient outcomes...

Transplant rejection mediated by the adaptive immune system remains a major barrier to achieving long-term tolerance and graft survival. Emerging evidence indicates that lymphocytes rapidly shift their metabolic programs in response to activation, co-stimulatory, and cytokine signals to support required effector cell differentiation and function. These observations have led to the hypothesis that manipulating the metabolic programs of immune cells could serve as a powerful therapeutic strategy for attenuating deleterious immune responses and facilitating durable tolerance in the setting of allogeneic solid organ or bone marrow transplant...

Early diagnosis of bacteremia for patients with suspected sepsis is 1 way to improve prognosis of sepsis. Systemic inflammatory response syndrome (SIRS) has long been utilized as a screening tool to detect bacteremia by front-line healthcare providers. The value of SIRS to predict bacteremia in elderly patients (≥65 years) with suspected sepsis has not yet been examined in emergency departments (EDs).We aimed to evaluate the performance of SIRS components in predicting bacteremia among elderly patients in EDs...

Yersinia pestis uses type III effector proteins to target eukaryotic signaling systems. The Yersinia outer protein (Yop) M effector from the Y. pestis strain is a critical virulence determinant; however, its role in Y. pestis pathogenesis is just beginning to emerge. Here we first identify YopM as the structural mimic of the bacterial IpaH E3 ligase family in vitro, and establish that the conserved CLD motif in its N-terminal is responsible for the E3 ligase function. Furthermore, we show that NLRP3 is a novel target of the YopM protein...

The consequences of the 2013-16 Ebola Zaire virus disease epidemic in West Africa were grave. The economies, healthcare systems and communities of Guinea, Sierra Leone and Liberia were devastated by over 18 months of active Ebola virus transmission, followed by sporadic resurgences potentially related to sexual transmission by survivors with viral persistence in body fluids following recovery. The need to develop and implement strategies to prevent and mitigate future outbreaks is now beyond dispute. The potential for unpredictable outbreaks of indeterminate duration, and control challenges posed by the possibility of sporadic re-emergence, mean that implementation of an effective vaccination programme for outbreak containment necessitates a vaccine providing durable immunity...

Oscillatory activity occurs in cortical and hippocampal networks with specific frequency ranges thought to be critical to working memory, attention, differentiation of neuronal precursors, and memory trace replay. Synchronized activity within relatively large neuronal populations is influenced by firing and bursting frequency within individual cells, and the latter is modulated by changes in intrinsic membrane excitability and synaptic transmission. Published work suggests that dopamine (DA), a potent modulator of learning and memory, acts on dopamine receptor 1-like dopamine receptors (D1Rs) to influence the phosphorylation and trafficking of glutamate receptor subunits, along with long-term potentiation (LTP) of excitatory synaptic transmission in striatum and prefrontal cortex...

With the number of stem cell-based therapies emerging on the increase, the need for novel and efficient delivery technologies to enable therapies to remain in damaged tissue and exert their therapeutic benefit for extended periods, has become a key requirement for their translation. Hydrogels, and in particular, thermoresponsive hydrogels, have the potential to act as such delivery systems. Thermoresponsive hydrogels, which are polymer solutions that transform into a gel upon a temperature increase, have a number of applications in the biomedical field due to their tendency to maintain a liquid state at room temperature, thereby enabling minimally invasive administration and a subsequent ability to form a robust gel upon heating to physiological temperature...

Prostate is an immune-competent organ normally populated by inflammatory cells. Prostatic inflammation origin can be multi-factorial and there are some emerging evidences on its possible role as a factor involved in prostate cancer (PC) pathogenesis and progression. This review critically analyzes the role of inflammation as a prognostic factor for progression and aggressiveness of PC. We verified the last 10 years literature data on the association between inflammation and PC aggressiveness, or PC response to therapies...

The rapid population growth in urban India has outpaced the municipal capacity to build essential infrastructures that make life in cities safe and healthy. Local and national governments alike are grappling with the challenges of urbanization with thousands migrating from villages to cities. Thus, urbanization in India has been accompanied by a concentration of poverty and urban public healthcare has emerged as one of the most pressing priorities facing our country. Newborn mortality rates in urban settings are lower than rural areas, early neonatal deaths account for greater proportion than late neonatal deaths...

An emerging neuropathological theory of Autism, referred to here as "the neural unreliability thesis," proposes greater variability in moment-to-moment cortical representation of environmental events, such that the system shows general instability in its impulse response function. Leading evidence for this thesis derives from functional neuroimaging, a methodology ill-suited for detailed assessment of sensory transmission dynamics occurring at the millisecond scale. Electrophysiological assessments of this thesis, however, are sparse and unconvincing...

The immune system of vertebrates confers protective mechanisms to the host through the sensing of stress-induced agents expressed during infection or cell stress. Among them, the first line of host defense composed of the innate immune sensing of these agents by pattern recognition receptors enables downstream adaptive immunity to be primed, mediating the body's appropriate response to clear infection and tissue damage. Mitochondria are «bacteria within» that allowed the emergence of functional eukaryotic cells by positioning themselves as the cell powerhouse and an initiator of cell death programs...
