D Carone, R Licenik, S Suri, L Griffanti, N Filippini, J Kennedy
Different strategies have been developed using Independent Component Analysis (ICA) to automatically de-noise fMRI data, either focusing on removing only certain components (e.g. motion-ICA-AROMA, Pruim et al., 2015a) or using more complex classifiers to remove multiple types of noise components (e.g. FIX, Salimi-Khorshidi et al., 2014 Griffanti et al., 2014). However, denoising data obtained in an acute setting might prove challenging: the presence of multiple noise sources may not allow focused strategies to clean the data enough and the heterogeneity in the data may be so great to critically undermine complex approaches...

REVIEW
Yara Barrense-Dias, André Berchtold, Joan-Carles Surís, Christina Akre
Sexting among youths has become a necessary topic of interest in research because of the negative consequences that this activity could create, especially when content is shared with others. Indeed, this loss of control could lead to humiliation, (cyber)bullying, or harassment. The development of new technologies, press coverage, and increase of prevalence rates could also explain the growth of interest in sexting. However, its definition is still a gray area. This review examines the different definitions of sexting used in the literature and its correlates...

PURPOSE: The CT angiography (CTA) spot sign is a strong predictor of hematoma expansion in intracerebral hemorrhage (ICH). However, CTA parameters vary widely across centers and may negatively impact spot sign accuracy in predicting ICH expansion. We developed a CT iodine calibration phantom that was scanned at different institutions in a large multicenter ICH clinical trial to determine the effect of image standardization on spot sign detection and performance. METHODS: A custom phantom containing known concentrations of iodine was designed and scanned using the stroke CT protocol at each institution...

Development passes through sensitive periods, during which plasticity allows for genetic and environmental factors to exert indelible influence on the maturation of the organism. In the context of central nervous system (CNS) development, such sensitive periods shape the formation of neuro-circuits that mediate, regulate, and control behavior. This general mechanism allows for development to be guided by both the genetic blueprint, as well as the environmental context. While allowing for adaptation, such sensitive periods are also windows of vulnerability during which external and internal factors can confer risk to brain disorders by derailing adaptive developmental programs...

REVIEW
Pawan Suri, Taruna K Aurora
Infectious conditions such as skin and soft tissue infections (SSTIs), Urogenital infections and peritonsillar abscesses frequently require care beyond emergency stabilization and are well-suited for short term care in an observation unit. SSTIs are a growing problem, partly due to emergence of strains of methicillin-resistant S. aureus (MRSA). Antibiotic choice is guided by the presence of purulence and site of infection. Purulent cellulitis is much more likely to be associated with MRSA. Radiographic imaging should be considered to aid in management in patients who are immunosuppressed, have persistent symptoms despite antibiotic therapy, recurrent infections, sepsis or diabetes...

Weaver syndrome is a rare overgrowth syndrome with distinct facial features in young children and variable learning disability. Heterozygous missense mutations in EZH2 are present in over 90% of patients with Weaver syndrome but the exact mechanism by which EZH2 mutations cause Weaver syndrome is unknown. We report an 11-year-old boy with a de novo 1.2-Mb deletion at 7q36.1 including EZH2 who has tall stature, significant intellectual disability, and some physical features of Weaver syndrome. Emerging evidence in the literature indicates that Weaver syndrome EZH2 mutations may result in loss of function of the gene and our report suggests that haploinsufficiency of EZH2 may replicate the clinical phenotype of Weaver syndrome...

Heat shock protein 70-2 (HSP70-2) is known to be involved in tumor progression. However, its molecular role and mechanism in epithelial ovarian cancer (EOC) remains unknown. In the present investigation, we examined the role of HSP70-2 in cell cycle, apoptosis and epithelial mesenchymal transition pathways in EOC cells in in vitro and in-vivo xenograft mouse model. To investigate the role of HSP70-2 in ovarian cancer, plasmid driven short hairpin RNA approach was used to examine HSP70-2 gene and protein expression in ovarian cancer cell line A-10 (origin: serous papillary cystadenocarcinoma), Caov-3 (origin: adenocarcinoma) and SKOV3 (origin: adenocarcinoma; derived from metastatic site: ascites) by RT-PCR, quantitative-PCR, immunohistochemistry and Western blotting...

LAMA2-related muscular dystrophy (LAMA2 MD or MDC1A) is the most frequent form of early-onset, fatal congenital muscular dystrophies. It is caused by mutations in LAMA2, the gene encoding laminin-α2, the long arm of the heterotrimeric (α2, β1, and γ1) basement membrane protein laminin-211 (Lm-211). We establish that despite compensatory expression of laminin-α4, giving rise to Lm-411 (α4, β1, and γ1), muscle basement membrane is labile in LAMA2 MD biopsies. Consistent with this deficit, recombinant Lm-411 polymerized and bound to cultured myotubes only weakly...

Entomopathogenic nematodes in the Heterorhabditis genus and their symbiotic Photorhabdus bacteria are important biocontrol agents of insect pests and models for the study of microbe-host interactions. In this work, we used larvae of the tobacco budworm (Heliothis virescens) as a model to study its defensive mechanisms against Heterorhabditis bacteriophora nematodes carrying symbiotic Photorhabdus temperata. We first determined time points of initial nematode entry and release of bacteria into the haemolymph to perform transcriptional analysis of insect gene expression during these steps in the infective process...

The injection of nitrate is one of the most commonly used technologies to impact the sulfur cycle in subsurface oil fields. Nitrate injection enhances the activity of nitrate-reducing bacteria, which produce nitrite inhibiting sulfate-reducing bacteria (SRB). Subsequent reduction of nitrate to di-nitrogen (N2) alleviates the inhibition of SRB by nitrite. It has been shown for the Medicine Hat Glauconitic C (MHGC) field, that alkylbenzenes especially toluene are important electron donors for the reduction of nitrate to nitrite and N2...

BACKGROUND: One-month dual antiplatelet treatment, with aspirin and clopidogrel, following internal carotid artery stent placement is the current standard of care to prevent in-stent thrombosis. Cilostazol, an antiplatelet drug, has been demonstrated to have a safety profile comparable to aspirin and clopidogrel. OBJECTIVE: To evaluate the safety and clinical efficacy of cilostazol and aspirin therapy following internal carotid artery stent placement up to 1 month postprocedure...
