N-glycosylation is an important co- and/or post-translational modification that occurs on the vast majority of the 1/3 of the mammalian proteome that traverses the cellular secretory pathway, regulating glycoprotein folding and functions. Previous studies on the sequence requirements for N-glycosylation have yielded the Asn-X-Ser/Thr (NXS/T) sequon and the enhanced aromatic sequons (Phe-X-Asn-X-Thr and Phe-X-X-Asn-X-Thr) which can be efficiently N-glycosylated. To further investigate the influence of sequence variation on N-glycosylation efficiency in the context of a 5-residue enhanced aromatic sequon, we used the human CD2 adhesion domain (hCD2ad) to screen the i-2, i-1, i+1 and i+2 residues flanking Asn at the i position...

PURPOSE OF REVIEW: To summarize the available literature regarding radiotherapy as a metastasis-directed therapy (MDT) in the treatment of oligometastatic prostate cancer (PCa). RECENT FINDINGS: Three different clinical scenarios of oligometastatic PCa exist in which MDT can be applied: de novo oligometastatic PCa, oligorecurrent PCa, and oligoprogressive PCa. A cut off of three to five metastatic lesions is most often used in these settings. Data from retrospective studies, treating over 1000 patients in total, have been reported...

We propose an occlusion compensation method for optical see-through head-mounted displays (OST-HMDs) equipped with a singlelayer transmissive spatial light modulator (SLM), in particular, a liquid crystal display (LCD). Occlusion is an important depth cue for 3D perception, yet realizing it on OST-HMDs is particularly difficult due to the displays' semitransparent nature. A key component for the occlusion support is the SLM-a device that can selectively interfere with light rays passing through it. For example, an LCD is a transmissive SLM that can block or pass incoming light rays by turning pixels black or transparent...

We are faced with a worldwide opiate/opioid epidemic that is devastating. According to the Centers for Disease Control and Prevention (CDC), at least 127 people, young and old, are dying every day in America due to narcotic overdose. The Food and Drug Administration (FDA) has approved Medication-Assisted Treatments (MATs) for opiate/opioids as well as alcohol and nicotine. The mechanism of action of most MATS favors either blocking of dopaminergic function or a form of Opiate Substitution Therapy (OST). These treatment options are adequate for short-term treatment of the symptoms of addiction and harm reduction but fail long-term to deal with the cause or lead to recovery...

Verticillium dahliae is the most overwhelming plant pathogen, causing Verticillium wilt in a number of economic crops. The molecular mechanism is still unclear and identification of the genes involved in the pathogenicity or virulence of this fungus would benefit to uncover such mechanism. STT3 is a catalytic subunit of the multi-subunit oligosaccharyl transferase (OST) and plays an essential role in glycoprotein modification. Here, we characterized STT3 gene (VDAG_03232.1) of V. dahliae to explore its regulatory role in the development and virulence by deletion and complementation of this gene, as well as its silence in transgenic plants...

INTRODUCTION: Globally, there is a considerable burden of HCV and HIV infections among people who inject drugs (PWID) and transmission of both infections continues. Needle and syringe programme (NSP) and opioid substitution therapy (OST) coverage remains low, despite evidence demonstrating their prevention benefit. Direct-acting antiviral therapies (DAA) with HCV cure >95% among PWID provide an opportunity to reverse rising trends in HCV-related morbidity and mortality and reduce incidence...

Anxiety disorders are among the most common disorders affecting youths in the general population, with up to 10% of children and 20% of adolescents meeting criteria for an anxiety disorder at any one point in time. Cognitive-behavior therapies (CBT), varying between 9 and 18 weeks of treatment, are considered evidence-based for the treatment of anxiety disorders in youth. During the last two decades treatments that are brief, intensive, or concentrated (BIC) have been developed and this meta-analysis includes 23 RCTs of these new approaches across the anxiety disorders...

PURPOSE OF REVIEW: Immunosenescence has been scrutinized in detail, and evidence that inflammation and ageing are interrelated is consistent. Still, a gold standard for assessing the biological age of the immune function in an individual patient is lacking, so that immunosenescence is still not a quantifiable criterion in clinical decision-making processes. RECENT FINDINGS: This review highlights recent (partly ongoing) studies into biomarkers of inflammation to assess immunosenescence, including large-scale studies, and quotes expert opinion statements...

Brown adipose tissue (BAT)-dependent thermogenesis and its suggested augmenting hormone, FGF21, are potential therapeutic targets in current obesity and diabetes research. Here, we studied the role of UCP1 and FGF21 for metabolic homeostasis in the cold and dissected underlying molecular mechanisms using UCP1-FGF21 double-knockout mice. We report that neither UCP1 nor FGF21, nor even compensatory increases of FGF21 serum levels in UCP1 knockout mice, are required for defense of body temperature or for maintenance of energy metabolism and body weight...

The one-session treatment (OST) approach for SPs is deemed well-established, and has been found to be highly effective for older children and adults; however, has not yet been trialled with very young children. The present study examines the preliminary effectiveness of play-modified OST for young children with a SP of dogs, using a multiple baseline controlled case series design. Treatment involved play modified one-session of intensive cognitive-behavioural therapy (OST plus Play) which was followed by brief telephone delivered maintenance calls over the 3 weeks immediately following treatment...

OBJECTIVES: Common mental disorders (CMDs) cause great individual suffering and long-term sick leave. Cognitive-behavioural therapy (CBT) effectively treats CMDs, but sick leave is not reduced to the same extent as psychiatric symptoms. Research results regarding return-to-work interventions (RTW-Is) and their effect on sick leave are inconclusive. The aim of this study was to evaluate CBT, a RTW-I and combined CBT and RTW-I (COMBO) for primary care patients on sick leave due to CMDs...

Osteoporosis is a silent disease until fractures occur, patient recognition is the greatest clinical challenge. Although more than 20 million women in the US are estimated to have established osteoporosis the majority are not appropriately identified. Bone densitometry is the current gold standard for diagnosis of osteoporosis; but may not be feasible or cost-effective to recommend for all postmenopausal women. Therefore, questionnaires incorporating risk factors have been developed to aid the clinician in identifying women with osteoporosis...
