BACKGROUND: Cranio-cervical flexion exercise (CCFE) is a representative exercise that activates the deep muscles of neck pain patients. However, there are a lack of studies that propose specific exercise methods to examine the more effective activity level of the deep cervical flexor. OBJECTIVE: The objective of this study is to propose a more effective exercise method through effect comparison based on an optimal degree of mouth-opening, a mouth-open versus mouth-closed position, eye gaze, and body position change during CCFE...

A MOF material, Co3[Co(CN)6]2 nanoparticles has been prepared for the effective detection of ethanol in vapor phase. When exposed to ethanol vapor, the material was changed from pink to purple, which is easily observed by naked eyes directly. We propose that the ethanol response is due to ethanol molecules entering the pores of the solid, where they alter the coordination geometry, leading to conversion of their Co centers from octahedral to tetrahedral coordination. Significantly, the change is reversible, which make the material reusable without subjecting to dynamic vacuum or slightly warming...

In this study, three nanos gene subtypes (Lcnanos1, Lcnanos2 and Lcnanos3) from Larimichthys crocea, were cloned and characterized. We determined the spatio-temporal expression patterns of each subtype in tissues as well as the cellular localization of mRNA in embryos. Results showed that deduced Nanos proteins have two main homology domains: N-terminal CCR4/NOT1 deadenylase interaction domain and highly conserved carboxy-terminal region bearing two conserved CCHC zinc-finger motifs. The expression levels of Lcnanos1 in testis were significantly higher than other tissues, followed by heart, brain, eye, and ovary...

BACKGROUND AND OBJECTIVES: Bilateral eye-movements (EMs) and visual mental imagery both require working memory resources. When performed together, they compete for these resources, which can cause various forms of mental imagery to become impaired (e.g., less vivid). This study aimed to examine whether EMs impair sexual fantasies (a form of mental imagery) in the same manner. METHODS: Eighty undergraduates (40 males, 40 females) took part in four counterbalanced conditions: (1) EMs and an experience-based sexual fantasy; (2) EMs and an imagination-based sexual fantasy; (3) experience-based sexual fantasy only; and (4) imagination-based sexual fantasy only...

BACKGROUND: In Germany reimbursement for new medical technologies is often enforced before a social court. It is likely that these judicial decisions also affect the sickness funds' decisions on requests for reimbursement and thus patient access to new technologies in general. OBJECTIVES: The aim of this study was to identify the technologies that have repeatedly generated court actions and whether these actions have been successful. The focus was on differences between sectors, technology groups and indications...

Endemic to Central Africa, loiasis - or African eye worm (caused by the filarial nematode Loa loa) - affects more than 10 million people. Despite causing ocular and systemic symptoms, it has typically been considered a benign condition, only of public health relevance because it impedes mass drug administration-based interventions against onchocerciasis and lymphatic filariasis in co-endemic areas. Recent research has challenged this conception, demonstrating excess mortality associated with high levels of infection, implying that loiasis warrants attention as an intrinsic public health problem...

Craniofacial muscles, muscles that move the eyes, control facial expression and allow food uptake and speech, have long been regarded as a variation on the general body muscle scheme. However, evidence has accumulated that the function of head muscles, their developmental anatomy and the underlying regulatory cascades are distinct. This article reviews the key aspects of craniofacial muscle and muscle stem cell formation and discusses how this differs from the trunk programme of myogenesis; we show novel RNAseq data to support this notion...

Autism Spectrum Disorder (ASD) is often accompanied by deficits in speech and language processing. Speech processing relies heavily on the integration of auditory and visual information, and it has been suggested that the ability to detect correspondence between auditory and visual signals helps to lay the foundation for successful language development. The goal of the present study was to examine whether young children with ASD show reduced sensitivity to temporal asynchronies in a speech processing task when compared to typically developing controls, and to examine how this sensitivity might relate to language proficiency...

Our focus of attention naturally fluctuates between different sources of information even when we desire to focus on a single object. Focused attention (FA) meditation is associated with greater control over this process, yet the neuronal mechanisms underlying this ability are not entirely understood. Here, we hypothesize that the capacity of attention to transiently focus and swiftly change relates to the critical dynamics emerging when neuronal systems balance at a point of instability between order and disorder...

The diversification of functional traits may be constrained by intrinsic factors, such as structural, mechanical, developmental, or physiological limitations. We explored the biomechanical and constructional constraints on the size of the major jaw closing muscles, the adductor mandibulae complex (AM), in a diverse clade of freshwater fish - the Neotropical cichlids. Using phylogenetic comparative methods, we contrasted patterns of size variation and diversification rates of three AM divisions with variables describing head size and biomechanical coefficients describing force and velocity transmission...

Heterozygous variants in the arginine-glutamic acid dipeptide repeats gene (RERE) have been shown to cause neurodevelopmental disorder with or without anomalies of the brain, eye, or heart (NEDBEH). Here we report nine individuals with NEDBEH who carry partial deletions or deleterious sequence variants in RERE. These variants were found to be de novo in all cases in which parental samples were available. An analysis of data from individuals with NEDBEH suggests that point mutations affecting the Atrophin-1 domain of RERE are associated with an increased risk of structural eye defects, congenital heart defects, renal anomalies and sensorineural hearing loss when compared to loss-of-function variants that are likely to lead to haploinsufficiency...
