Background: Preventing anterior cruciate ligament(ACL) inj.ries is important to avoid long-term adverse health consequences. Identifying barriers to implementation of these prevention programs is crucial to reducing the incidence of these inj.ries. Our purpose was to identify barriers of implementation for ACL inj.ry prevention programs and suggest mechanisms for reducing the barriers through application of a SocioEcological Model(SEM).Methods: Studies investigating ACL prevention program effectiveness were searched in Medline via PubMed and the Cochrane Library, and a subsequent review of the references of the identified articles, yielded 15 articles total. Inclusion criteria encompassed prospective controlled trials, published in English, with ACL inj.ries as the primary outcome. Studies were independently appraised by 2 reviewers for methodological quality using the PEDro scale. Barriers to implementation were identified when reported in at least 2 separate studies. A SEM was used to suggest ways to reduce the identified ***: Five barriers were identified: motivation, time requirements, skill requirements for program facilitators, compliance, and cost. The SEM suggested ways to minimize the barriers at all levels of the model from the individual through policy ***: Identification of barriers to program implementation and suggesting how to reduce them through the SEM is a critical first step toward enabling ACL prevention programs to be more effective and ultimately reducing the incidence of these inj.ries.

Background: We investigated the influence of a botanical agent to improve sleep quality and associated measures in men and women with self-reported difficulty sleeping. Methods: 32 individuals were randomly assigned in double blind manner to ingest a botanical agent (CLOCK?, containing Rosemary [Rosmarinus officinalis] and Daylily [Hemerocallis fulva]) or a placebo over a 6-week intervention. During weeks 1 and 2, subj.cts ingested one serving of the assigned condition, followed by a two-week washout. During weeks 5 and 6, subj.cts ingested two servings of the condition. The Leeds Sleep Evaluation Questionnaire was used as an outcome measure, as were subj.ctive measures of sleep quality, energy level, and mood. Blood samples collected pre- and post-intervention were assayed for acetylcholine (ACH), brain-derived neurotrophic factor (BDNF), irisin, and melatonin. Results: No differences were noted between conditions in measures of sleep (p > 0.05). While no differences of statistical significance were noted in subj.ctive feelings, during weeks 5 and 6 as compared to baseline, subj.cts assigned to the supplement noted an 8% increase in attentiveness, an 11% increase in alertness, a 12% increase in focus, a 14% increase in feeling energetic, a 12% increase in enthusiasm, a 23% increase in feeling well rested, an 11% decrease in feeling sluggish, and a 16% decrease in feeling depressed, without the same improvement observed for subj.cts in the placebo group. All biochemical measures were increased from pre- to post-treatment with two servings of the supplement;the largest percent increase noted for BDNF (27%) and the largest effect size noted for irisin (d = 1.36). Biochemical values for the placebo condition were unchanged. Conclusions: CLOCK? may have an impact on certain measurements of mood, with a significant impact on the biochemical marker, BDNF. Future studies using a larger sample size and perhaps a cross-over design may help to further clarify the impact of th

An Arabidopsis Lipid Flippase Is Required for Timely Recruitment of Defenses to the Host- Pathogen Interface at the Plant Cell Surface

引用

Molecular Plant 2017年第6期10卷 805-820页

Deposition of cell wall-reinforcing papillae is an integral component of the plant immune response. TheArabidopsis PENETRATION 3 （PEN3） ATP binding cassette （ABC） transporter plays a role in defense against numerous pathogens and is recruited to sites of pathogen detection where it accumulates within papillae. However, the trafficking pathways and regulatory mechanisms contributing to recruitment of PEN3 and other defenses to the host-pathogen interface are poorly understood. Here, we report a confocal microscopy-based screen to identify mutants with altered localization of PEN3-GFP after inoculation with powdery mildew fungi. We identified a mutant, aberrant localization of PEN3 3 （alp3）, displaying accumulation of the normally plasma membrane （PM）-Iocalized PEN3-GFP in endomembrane compartments. The mutant was found to be disrupted in the P4-ATPase AMINOPHOSPHOLIPID ATPASE 3 （ALA3）, a lipid flippase that plays a critical role in vesicle formation. We provide evidence that PEN3 undergoes continuous endocytic cycling from the PM to the trans-Golgi network （TGN）. In alp3, PEN3 accumulates in the TGN, causing delays in recruitment to the host-pathogen interface. Our results indicate that PEN3 and other defense proteins continuously cycle through the TGN and that timely exit of these proteins from the TGN is critical for effective pre-invasive immune responses against powdery mildews.

AIM To test associations between statin use and cognitive impairment in adults with childhood-onset type 1 diabetes(T1D).METHODS In 2010-13, n = 108 middle-aged participants from ongoing observational Pittsburgh Epidemiology of Diabetes Complications Study underwent neurocognitive assessment(mean age and T1 D duration of 49 and 41 years, respectively). All were diagnosed with childhoodonset(i.e., prior to age 18) T1 D between 1950 and 1980 and were seen within one year of diagnosis at Children's Hospital of Pittsburgh. Self-reported statin use(yes/no and if yes, name of statin) was collected biennially from parent study baseline(1986-1988) to time of neurocognitive testing. Logistic regression models tested associations between statin use groups and cognitive impairment(defined as having two or more cognitive test scores 1.5SD or worse than published norms) while linear regression models tested associations between statin use groups and cognitive domain z-scores(domains: Verbal IQ, memory, executive function, psychomotor speed, and visuo-construction). All models controlled for education and age. To address confounding by indication, models were repeated using a propensity score for statin *** Of the 108 participants, 51 reported never using statins. Median duration of statin use among the 57 ever users was 6 years. These 57 ever statin users were split to create two groups(≤ or > median years of statin use): 1-6 years(n = 25), and 7-12 years(n = 32). Compared with never users, using statins 1-6 years tripled the odds of cognitive impairment(OR = 3.16; 95%CI: 0.93-10.72; P = 0.06) and using statins 7-12 years almost quintupled the odds of cognitive impairment(OR = 4.84; 95%CI: 1.63-14.44; P = 0.005). Compared with never users, using statins 1-6 or 7-12 years was related to worse performance in the memory domain(β =-0.52; P = 0.003, and-0.39; P = 0.014, respectively).

Diffuse idiopathic skeletal hyperostosis(DISH) is a prevalent noninflammatory spondyloarthropathy characterized by ectopic mineral formation along the anterolateral aspect of the vertebral column, yet little is known about its underlying pathogenesis. Our obj.ctive was to evaluate the histopathological features and composition of ectopic mineral within spinal tissues affected by DISH in humans. Thoracic spine segments from six embalmed cadaveric donors(one female and five males;median age 82 years)meeting the radiographic diagnostic criteria for DISH were evaluated using radiological, histological, and physical analyses. Overall,the histological features of ectopic mineralization at individual motion segments were heterogeneous, including regions of heterotopic ossification and dystrophic calcification. Heterotopic ossifications were characterized by woven and lamellar bone,multifocal areas of metaplastic cartilage, and bony bridges along the anterior aspect of the intervertebral disc space. Dystrophic calcifications were characterized by an amorphous appearance, a high content of calcium and phosphorus, an X-ray diffraction pattern matching that of hydroxyapatite, and radiodensities exceeding that of cortical bone. Dystrophic calcifications were found within the anterior longitudinal ligament and annulus fibrosus in motion segments both meeting and not meeting the radiographic criteria for DISH. In summary, our findings indicate that in DISH, ectopic mineral forms along the anterior aspect of the spine by both heterotopic ossification and dystrophic calcification of fibrocartilaginous tissues. Although both types of ectopic mineralization are captured by current radiographic criteria for DISH, dystrophic calcification may reflect a distinct disease process or an early stage in the pathogenesis of DISH.

Obj.ctive: Patients with BRAF-mutant colorectal cancer(CRC) have a poor prognosis. Molecular status is not currently used to select which drug to use in combination with radiotherapy. Our aim was to identify drugs that radiosensitise CRC cells with known BRAF ***: We screened 298 oncological drugs with and without ionising radiation in colorectal cancer cells isogenic for BRAF. Hits from rank product analysis were validated in a 16-cell line panel of human CRC cell lines, using clonogenic survival assays and xenograft models in ***: Most consistently identified hits were drugs targeting cell growth/proliferation or DNA damage repair. The most effective class of drugs that radiosensitised wild-type and mutant cell lines was PARP inhibitors. In clonogenic survival assays, talazoparib produced a radiation enhancement ratio of 1.9 in DLD1(BRAF-wildtype) cells and 1.8 in RKO(BRAF V600 E) cells. In DLD1 xenografts, talazoparib significantly increased the inhibitory effect of radiation on tumour growth(P ≤ 0.01).Conclusions: Our method for screening large drug libraries for radiosensitisation has identified PARP inhibitors as promising radiosensitisers of colorectal cancer cells with wild-type and mutant BRAF backgrounds.

Molecular regulation of sucrose catabolism and sugar transport for development~ defence and phloem function

引用

j.urnal of Integrative Plant Biology 2017年第5期59卷 322-335页

作者： j.n Li Limin Wu ryan Foster Yong-Ling Ruan Australia-China Research Centre for Crop Improvement and School of Environmental and Life Sciences The University of NewcastleNSW 2308 Australia CSIRO Agriculture Canberra ACT 26oi Australia

Sucrose （Suc） is the maj.r end product of photosynthesis in mesophyll cells of most vascular plants. It is loaded into phloem of mature leaves for long-distance translocation to non-photosynthetic organs where it is unloaded for diverse uses. Clearly, Suc transport and metabolism is central to plant growth and development and the functionality of the entire vascular system. Despite vast information in the literature about the physiological roles of individual sugar metabolic enzymes and transporters, there is a lack of systematic evaluation about their molecular regulation from transcriptional to post-translational levels. Knowledge on this topic is essential for understanding and improving plant development, optimizing resource distri- bution and increasing crop productivity. We therefore focused our analyses on molecular control of key players in Suc metabolism and transport, including：（i） the identifica- tion of promoter elements responsive to sugars and hormones or targeted by transcription factors and micro- RNAs degrading transcripts of target genes; and （ii） modulation of enzyme and transporter activities through protein-protein interactions and other post-translational modifications. We have highlighted maj.r remaining questions and discussed opportunities to exploit current understanding to gain new insights into molecular control of carbon partitioning for improving plant performance.
