Mingmin Wu, Xiaoyong Wang, Kun Wang, Zijian Guo
Trypsin and its inhibitors are relevant to many physiological processes and diseases. In this study, a nanosensor capable of detecting trypsin and its inhibitors was designed based on the fluorescence resonance energy transfer (FRET) between upconversion nanoparticle (UCNP) and gold nanoparticle (AuNP). UCNP and AuNP were linked by a trypsin-sensitive peptide DDDDARC, forming the non-fluorescent UCNP-peptide-AuNP nanosensor. In the presence of trypsin, the peptide was cleaved and the quenched fluorescence was restored; in the presence of trypsin inhibitors, the recovery of the fluorescence was decreased...

The development of a portable testing device for detecting Human Salivary α-Amylase (HSA) is very timely since such an enzyme is a valuable biomarker for diagnosing many diseases and monitoring the human stress. We show that an easy-to-use and robust device like the Quartz-Crystal Microbalance (QCM) can be a suitable platform for HSA sensing with a limit of detection of 1µg/mL (77 U/L). The functionalization of the gold surface is realized by the Photochemical Immobilization Technique (PIT), a powerful and simple method based on an appropriate UV-activation of antibodies...

Dietary habits and, in particular, the intake frequency of sucrose are of major importance for the development of dental caries. The perception of sweet taste is believed to have an influence on sucrose intake and therefore affects the predisposition to dental caries. The aim was to study the caries experience and sweet taste perception and to further analyze the possible relationship between the 2 tested variables in 13- to 15-year-old children from 3 different geographical areas. A cross-sectional survey comprising 669 children (220 Italian, 224 Mexican, and 225 Saudi Arabian) was conducted...

BACKGROUND/AIMS: Driving cessation is associated with significant morbidity in older people. People with mild cognitive impairment (MCI) may be at particular risk of this. Very little research has examined driving in this population. Given this, we sought to identify predictors of driving cessation in people with MCI. METHODS: One hundred and eighty-five people with MCI were recruited from 9 memory clinics around Australia. People with MCI and their carers reported their driving status and completed measures of cognition, function, neuropsychiatric symptoms, and medication use at regular intervals over a 3-year period...

BACKGROUND: Auditory verbal hallucinations (AVH) are experienced by 21-54% of patients diagnosed with a borderline personality disorder (BPD), and ensuing distress is often high. Little is known about the beliefs these patients foster about their voices, and the influence thereof on distress and need for hospitalisation. METHODS: In a convenience sample of 38 BPD outpatients with AVH, data were collected with the aid of the Psychotic Symptom Rating Scales (PSYRATS), Beliefs about Voices Questionnaire (BAVQ), Social Comparison Rating Scale (SCRS), and Voice Power Differential Scale (VPDS)...

"Sleep Medicine" is now a specialty in its own right. Currently, there is increasing recognition of the very negative impact sleep disorders have on learning, education, safety, and quality of life. Technological advances will help us to break down diagnoses (e.g., narcolepsy has now been subdivided into types 1 and 2, depending upon the hypocretin levels in the spinal fluid) and to discover relationships to other bodily systems (e.g., type 1 narcolepsy potentially being an autoimmune disorder). The modern lifestyle of many, as characterized by a shortening of sleep periods, shift work, jet lag, and the need to be constantly available, means that advances in sleep medicine may result in a major understanding of more balanced "work-rest lifestyle" modifications...

non-adherence in patients with schizophrenia is the most common reason for a relapse of psychosis. In a cohort of participants in Pakistan who suffered a relapse of psychosis, we aimed to identify the principal factors associated with non-adherence, including any culture specific factors that might not be as significant in other jurisdictions. Semi-structured interviews were undertaken at four psychiatric hospitals in the Peshawar region in Pakistan with 55 participants (44 male and 11 female) diagnosed with schizophrenia, who had suffered a relapse of psychosis subsequent to treatment non-adherence...

OBJECTIVES: Advancing paternal age has been associated with several neuropsychiatric disorders in children. However, there is limited understanding of this association with obsessive compulsive disorder (OCD) and Tourette syndrome/chronic tic disorder (TS/CT) with inconsistent findings. We examined the association between parental age and offspring OCD and TS/CT. METHODS: This nested case-control study used the Finnish Hospital Discharge Register (FHDR) to identify 1358 individuals with OCD and 1195 with TS/CT, born from 1991 to 2009 and diagnosed by 2010...

Importance: Mutations in APP, PSEN1, and PSEN2 lead to early-onset Alzheimer disease (EOAD) but account for only approximately 11% of EOAD overall, leaving most of the genetic risk for the most severe form of Alzheimer disease unexplained. This extreme phenotype likely harbors highly penetrant risk variants, making it primed for discovery of novel risk genes and pathways for AD. Objective: To search for rare variants contributing to the risk for EOAD. Design, Setting, and Participants: In this case-control study, whole-exome sequencing (WES) was performed in 51 non-Hispanic white (NHW) patients with EOAD (age at onset <65 years) and 19 Caribbean Hispanic families previously screened as negative for established APP, PSEN1, and PSEN2 causal variants...
