Yingjie Liu, Suqian Ma, Bin Xu, Wenjing Tian
Aggregation-induced emission (AIE) provides a new way of achieving highly efficient luminescent materials. In this contribution, the self-assembly behavior, molecular stacking structure and photophysical properties of two polymorphs of a supramolecular co-crystal (C1 and C2) are investigated. The block-like crystal C1, packed in segregated stacking with strong π-π interactions between the H and G molecules, shows weak green emission with a low efficiency (ΦF) of 2%. In comparison, the needle-like crystal C2, packed in segregated stacking with no obviously strong intermolecular interactions, shows bright yellow emission...

Snail is one of the worst causes of food allergy. Thus, the aim of this study was to identify the major and minor allergens of the local marine snail (Cerithidea obtusa) and subsequently to investigate the impacts of heat treatment on the IgE-binding activity of snail allergens. Proteins from raw and heat-treated snails (boiled, roasted and fried) were extracted and then resolved by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Immunoblotting of all extracts were then performed using sera from patients with snail allergy...

BACKGROUND: Based on experimental research on threat extinction, individuals exposed to repeated traumatic events may have impaired outcome in exposure therapy compared to those who have experienced a single trauma (Lang & McTeague, ). This study examined whether repeated trauma exposure predicts smaller changes in self-reported distress during imaginal exposure and worse outcomes for patients with posttraumatic stress disorder (PTSD). METHODS: Adults (N = 116) with chronic PTSD received up to 10 sessions of prolonged exposure (PE) therapy...

Early mathematics knowledge is a strong predictor of later academic achievement, but children from low-income families enter school with weak mathematics knowledge. An early math trajectories model is proposed and evaluated within a longitudinal study of 517 low-income American children from ages 4 to 11. This model includes a broad range of math topics, as well as potential pathways from preschool to middle grades mathematics achievement. In preschool, nonsymbolic quantity, counting, and patterning knowledge predicted fifth-grade mathematics achievement...

BACKGROUND: Myopia is a major public health concern throughout the world and the prevalence has been increasing rapidly in recent years, especially in urban Asia. The "vitamin D hypothesis" has been raised recently because vitamin D may be a link between less time outdoors and increased risk of myopia. METHODS: We reviewed all studies published in English which examined the association of time outdoors and blood vitamin D status with myopia. RESULTS: The protective effect of time spent outdoors on the risk of myopia onset has been well-established with numerous observational studies and three trials published...

Some individuals with developmental disabilities develop inappropriate sexual behaviors such as public masturbation, disrobing, and touching others in an unwanted sexual manner. Such acts are problematic given the taboo nature of the behaviors and the potential for significant negative consequences, such as restricted community access, injury, and legal ramifications. Therefore, it is necessary to equip caregivers and practitioners with effective treatment options. The purpose of this paper is to review studies that have evaluated behavioral treatments to reduce inappropriate sexual behavior in persons with developmental disabilities...

At 100 K, the title mol-ecular salt, C3H8NO(+)·C2F6NO4S2(-), has ortho-rhom-bic (P212121) symmetry; the amino H atom of bis-(tri-fluoro-methane-sulfon-yl)amine (HNTf2) was transferred to the basic O atom of di-methyl-formamide (DMF) when the ionic liquid components were mixed. The structure displays an O-H⋯N hydrogen bond, which links the cation to the anion, which is reinforced by a non-conventional C-H⋯O inter-action, generating an R2(2)(7) loop. A further very weak C-H⋯O inter-action generates an [001] chain...

The title compound, [ReCl(pyAm)(CO)3], where pyAm is 1-[(pyridin-2-yl-methyl-idene)amino]-adamantane (C16H20N2), was synthesized from the reaction of [ReCl(CO)5] and pyAm in an equimolar ratio. The Re(I) atom resides in an octa-hedral C3ClN2 coordination sphere. The Re-C bond trans to the chloride ligand is noticeably longer compared to the other two Re-C distances. Weak C-H⋯Cl hydrogen-bonding inter-actions consoldiate the packing of the mol-ecules. In this design, the pyAm ligand was employed due to its well-known pharmacokinetic properties...

In the title compound, C11H13N3O, the seven-membered ring adopts a conformation such that the three atoms not involved in the aromatic plane lie on the same side of that plane. One hydrazinic H atom forms an intra-molecular hydrogen bond to the O atom; the other forms a classical inter-molecular hydrogen bond N-H⋯O, which combines with a 'weak' Har⋯O inter-action to build up double layers of mol-ecules parallel to the bc plane.

Since the pioneering studies of the 1960s, heart rate variability (HRV) has become an increasingly used non-invasive tool for examining cardiac autonomic functions and dysfunctions in various populations and conditions. Many calculation methods have been developed to address these issues, each with their strengths and weaknesses. Although, its interpretation may remain difficult, this technique provides, from a non-invasive approach, reliable physiological information that was previously inaccessible, in many fields including death and health prediction, training and overtraining, cardiac and respiratory rehabilitation, sleep-disordered breathing, large cohort follow-ups, children's autonomic status, anesthesia, or neurophysiological studies...

Subdural arteriovenous fistula (SDAVF) is a rare condition characterized by clinical manifestations ranging from mild bilateral sensory deficits to quadriplegia. The diagnosis is often delayed due to unspecific neurological symptoms, initially diagnosed as polyneuropathy or myelopathy. The diagnosis can be delayed for as long as 1-15 years. The following report describes a cervical SDAVF case initially misdiagnosed as myelitis transversa and treated with intravenous steroids. A 56-year-old male presented with sensory deficits and mild leg and right arm weakness...

INTRODUCTION: BODE index, a multidimensional grading system which is based on Body mass index, airway Obstruction, Dyspnea scale, and Exercise capacity, has been increasingly used for the evaluation of chronic obstructive pulmonary disease (COPD). Many of the systemic manifestations of COPD are shown to be mediated by elevated levels of proinflammatory biomarkers. OBJECTIVE: We aimed to investigate the relationship between the BODE index, its components, disease severity, and proinflammatory biomarkers like C-reactive protein (CRP), tumor necrosis factor (TNF)-α, and interleukin (IL)-6...
