BACKGROUND: Accurate tissue sampling in nonenhancing (NE) gliomas is a unique surgical challenge due to their intratumoral histological heterogeneity and absence of contrast enhancement as a guide for intraoperative stereotactic guidance. Instead, T2/fluid-attenuated inversion-recovery (FLAIR) hyperintensity on MRI is commonly used as an imaging surrogate for pathological tissue, but sampling from this region can yield nondiagnostic or underdiagnostic brain tissue. Sodium fluorescein is an intraoperative fluorescent dye that has a high predictive value for tumor identification in areas of contrast enhancement and NE in glioblastomas...

Introduction: Online cigarette dealers have lower prices than brick-and-mortar retailers and advertise tax-free status 1-8. Previous studies show smokers search out these online alternatives at the time of a cigarette tax increase 9-10. However, these studies rely upon researchers' decision to consider a specific date and preclude the possibility that researchers focus on the wrong date. The purpose of this study is to introduce an unbiased methodology to the field of observing search patterns and to use this methodology to determine whether smokers search Google for "cheap cigarettes" at cigarette tax increases and, if so, whether the increased level of searches persists...

Retinoic acid receptor α (RARα) plays a crucial role in kidney disease. However, the underlying mechanisms in glomerulosclerosis (GS) is still not clear. The roles of RARα in an adriamycin (ADR)-induced GS rat model and in ADR-induced podocyte injury in vitro were investigated. RARα was over-expressed in GS rats, and serum, urine and kidney samples were collected to detect the induction of the expression of the receptor. RARα expression was inhibited and/or over-expressed in cultured podocytes following injury, as demonstrated by morphometric assays, cell toxicity, and matrix metalloproteinase (MMP) enzymatic activity...

In rats, learning and memory performance decline during normal aging, which makes this rodent species a suitable model to evaluate therapeutic strategies. In aging rats, insulin-like growth factor-I (IGF-I), is known to significantly improve spatial memory accuracy as compared to control counterparts. A constellation of gene expression changes underlie the hippocampal phenotype of aging but no studies on the effects of IGF-I on the hippocampal transcriptome of old rodents have been documented. Here, we assessed the effects of IGF-I gene therapy on spatial memory performance in old female rats and compared them with changes in the hippocampal transcriptome...

Medication adherence is essential to promote the health of people living with HIV (PL-HIV) and prevent HIV transmission in the U.S. Novel medication health promotion interventions are needed that address patient-centeredness, understandability, and communication with providers. The aims of this article are to define the systematic stages we used to develop an effective health promotion intervention via the products (e.g. images and stories) of Photovoice. We designed an intervention to improve HIV adherence knowledge, attitudes, and communication with providers through Photovoice...

Virag Sharma, Michael Hiller
Genome alignments provide a powerful basis to transfer gene annotations from a well-annotated reference genome to many other aligned genomes. The completeness of these annotations crucially depends on the sensitivity of the underlying genome alignment. Here, we investigated the impact of the genome alignment parameters and found that parameters with a higher sensitivity allow the detection of thousands of novel alignments between orthologous exons that have been missed before. In particular, comparisons between species separated by an evolutionary distance of >0...

Heregulins (HRGs) bind to the receptors HER3 or HER4, induce receptor dimerization, and trigger downstream signaling that leads to tumor progression and resistance to targeted therapies. Increased expression of HRGs has been associated with worse clinical prognosis; therefore, attempts to block HRG-dependent tumor growth have been pursued. This manuscript summarizes the function and signaling of HRGs and review the preclinical evidence of its involvement in carcinogenesis, prognosis, and treatment resistance in several malignancies such as colorectal cancer, non-small cell lung cancer, ovarian cancer, and breast cancer...

Squamous cell carcinoma (SCC) is the sixth most frequent malignant tumor of the head and neck region. Despite advances in therapeutic options over the last decades, the rate of mortality and morbidity has not been improved markedly. A small subset of cells, cancer stem cells (CSCs), with self-renewal properties have become a major focus of current cancer research. CD44 and p63 are identified as candidate stem cell markers in normal squamous epithelium and SCC. The role of these markers in oral squamous cell carcinoma (OSCC) is still debatable...

In the past few years, the Cas9 endonuclease from the type II CRISPR-Cas bacterial antiviral defense system has revolutionized the genome editing field. Guided by an RNA molecule, Cas9 can be reprogrammed to target almost any DNA sequence: the only limitation being the short nucleotide sequence in the vicinity of the target, termed the PAM, which is characteristic for each Cas9 protein. Streptococcus pyogenes Cas9 which recognizes the NGG PAM is currently most widely used for genome manipulation. However, Cas9 orthologues and engineered Cas9 variants offer expanded genome targeting capabilities, improved specificity and biochemical properties...

The Timed Up and Go (TUG) has been commonly used for fall risk assessment. The instrumented Timed Up and Go (iTUG) adds wearable sensors to capture sub-movements and may be more sensitive. Posturography assessments have also been used for determining fall risk. This study used stepwise logistic regression models to identify key outcome measures for the iTUG and posturography protocols. The effectiveness of the models containing these measures in differentiating fallers from non-fallers were then compared for each: iTUG total time duration only, iTUG, posturography, and combined iTUG and posturography assessments...

RATIONALE: When evaluating complex, tailorable digital behavioural interventions, additional approaches may be required alongside established methodologies such as randomised controlled trials (RCTs). Research evaluating a computer-assisted therapy (CAT) programme for substance misuse, Breaking Free Online (BFO), is informed by Medical Research Council (MRC) guidance recommending examination of 'mechanisms of action' of individual intervention strategies, which is relevant when evaluating digital interventions with content that may evolve over time...

Typing of different portions of the feline mitochondrial control region has illustrated pronounced differences in haplotype distributions between cats from the Netherlands and other parts of the world. To gain a better understanding of the haplotype distribution of North West Continental Europe, 605bp of mitochondrial DNA was typed from randomly selected cats from the Netherlands (N=146), Belgium (N=64) and South West Germany (N=128). The genetic differences between these randomly sampled European populations correlate to the geographical distances, with the Dutch and the South West German populations furthest apart and the Belgian population as an intermediate (Fst values 0...

This study explored the influence of attachment on psychiatric treatment by considering attitudes towards and the use of psychotropic medication and psychotherapy in patients with depressive and anxiety disorders. Adults referred to a psychiatrist completed self-report measures and participated in a diagnostic interview based on DSM-IV criteria. Those with depressive, anxiety or adjustment disorders were included (n = 124). Patients reported the types and dosage of current psychotropic medication as well as number of different psychiatrists and psychologists/counselors they had seen in the past 10 years...

Facial affect recognition (FAR) accuracy is impaired in schizophrenia and, to a lesser extent, in individuals at-risk for psychosis. Reduced reaction time and negative bias on FAR tasks are also evident in schizophrenia, though few studies have examined these measures in at-risk samples. Social dysfunction is associated with FAR deficits in schizophrenia and at-risk individuals. We aimed to elucidate the nature of FAR and social functioning among individuals from a non-clinical population reporting a range of schizotypal traits (i...

Mentalization, operationalized as reflective functioning (RF), can play a crucial role in the psychological mechanisms underlying personality functioning. This study aimed to: (a) study the association between RF, personality disorders (cluster level) and functioning; (b) investigate whether RF and personality functioning are influenced by (secure vs. insecure) attachment; and (c) explore the potential mediating effect of RF on the relationship between attachment and personality functioning. The Shedler-Westen Assessment Procedure (SWAP-200) was used to assess personality disorders and levels of psychological functioning in a clinical sample (N = 88)...
