The Internet’s permeation into daily life has profoundly changed the practice of psychiatry with adolescents, who mobilize online social media and related technologies in their efforts to develop identity and “hang out” with peers. Technology offers both challenges and opportunities to mental health professionals working with teens. Practitioners will need a new skill-set, including keepi...



Investigating human disease using stem cell models
submitted by silsay74 22 minutes ago - Topic: Biology
Understanding disease pathogenesis and developing potential therapies require accurate and genetically tractable models. This Review discusses how human stem cells — including embryonic stem cells, adult stem cells and induced pluripotent stem cells — can provide informative models of diverse human diseases. Such methods can also be extended through gene editing, co-culture or infectious ag...

How resistant is ‘treatment-resistant’ obsessive-compulsive disorder in youth?
submitted by nelemo2077 26 minutes ago - Topic: Health
Obsessive-compulsive disorder (OCD) is often perceived as being difficult to treat. This study aimed to test the hypothesis that treatment non-response in routine clinical practice is often due to failures in the delivery of treatment, and that most patients who are apparently treatment-resistant will respond to treatment if adequately delivered. Retrospective cohort data analysis. Forty-three ...

Preventive dental health care experiences of preschool-age children with special health care needs
submitted by vencieadeco 50 minutes ago - Topic: Health
This study examined the preventive dental health care experiences of young children with special needs and determined the feasibility of conducting clinical dental examinations at a community-based early intervention services center. Study methods included 90 parent interviews and dental examinations of their preschool-age children. Thirteen percent of the children received optimal preventive c...



A comparison of compliance in medicaid versus non-Medicaid patients
submitted by vencieadeco 50 minutes ago - Topic: Health
Medicaid patients have been associated with lack of compliance during their orthodontic treatment in comparison with the non-Medicaid patients. In this study, Medicaid and non-Medicaid orthodontic patients’ compliance from a state university and private practice orthodontic clinic within close location were analyzed. Charts of 30 Medicaid and 30 non-Medicaid orthodontic patients at each ortho...

Distribution of permanent canine agenesis in Down syndrome: 15 cases from a Centre for Special Care Dentistry
submitted by vencieadeco 50 minutes ago - Topic: Health
The purpose of this study was to investigate the distribution of permanent canine agenesis in subjects with Down syndrome (DS). Subjects with canine agenesis were determined by means of panoramic radiographs from 150 DS subjects attending a center for special care dentistry. Our results confirm the high prevalence of agenetic canines in DS (21 canines, 14%). We found specific effects on the dis...


In vitro compressive fracture resistance of human maxillary first premolar with different mesial occlusal distal cavity
submitted by pwegener 56 minutes ago - Topic: Health
The purpose of this study was to determine fracture loads of human maxillary first premolars restored with condensable composite resin (Surefil, Dentsply) or leucite-reinforced ceramic inlays (ProCAD, Ivoclar Vivadent) in mesial occlusal distal cavity preparations of differing pulpal depths and isthmus widths. Ninety freshly extracted intact maxillary first premolars were divided into nine grou...

submitted by pwegener 56 minutes ago - Topic: Health
Dental patients with mental, psychiatric, or neurological disorders may need general anesthesia during dental treatments. This study analyzed the dental treatments and postoperative complications of 200 dental patients in a special needs dental clinic in northern Taiwan. The dental treatments and postoperative complications of 200 dental patients who needed general anesthesia for performing the...


Oral bacterial inactivation using a novel low-temperature atmospheric-pressure plasma device
submitted by pwegener 56 minutes ago - Topic: Health
Atmospheric-pressure plasma is a new technology for biomedical applications. Utilization of an ionized gas (plasma) to achieve disinfection is an alternative sterilization technique that has become popular recently due to its safety, cost effectiveness, and superior performance to traditional methods. The purpose of this study was to evaluate the germicidal effectiveness of a low-temperature at...

The effect of pouring time on the dimensional stability of casts made from conventional and extended-pour irreversible hydrocolloids by 3D modelling
submitted by pwegener 56 minutes ago - Topic: Health
The aim of this study was to determine the accuracy of casts made from irreversible hydrocolloid impressions with immediate and delayed pouring. A master model was mounted on a modified articulator designed to standardize impression procedures. A total of 250 impressions were taken and grouped into 25 groups (n = 10) according to irreversible hydrocolloid material (CA37, Tropicalgin, ColorCha...

An implementation of Bayesian lensing shear measurement
submitted by pheleppi 1 hour ago - Topic: Geography
The Bayesian gravitational shear estimation algorithm developed by Bernstein & Armstrong can potentially be used to overcome multiplicative noise bias and recover shear using very low signal-to-noise ratio (S/N) galaxy images. In that work, the authors confirmed that the method is nearly unbiased in a simplified demonstration, but no test was performed on images with realistic pixel noise. ...

A toy model for the X-ray spectral variability of active galactic nuclei
submitted by pheleppi 1 hour ago - Topic: Geography
Investigations into the long-term X-ray spectral variability of 10 active galactic nuclei (AGNs) revealed a positive spectral index–flux correlation for each object. An inner advection-dominated accretion flow (ADAF) may connect to a thin disc/corona at a certain transition radius. Both these structures are responsible for the hard X-ray emission in AGNs. The ADAF is hot and its X-ray spe...
