Dear Editor,ETadegn TagedPFailure to meet World Health Organization(WHO)-determined minimum physical activity(PA)levels is an established risk factor for cardiovascular disease(CVD),^(1)but evidence is still scarce on its effects on other CVD risk factors.Furthermore,whether or not there are sex-specific effects on the association between PA and CVD risk is a matter of controversy,with some authors observing a protective effect of PA in men but not in women,^(2)and others finding the opposite trend.^(3)

Memory deficit,which is often associated with aging and many psychiatric,neurological,and neurodegenerative diseases,has been a challenging issue for treatment.Up till now,all potential drug candidates have failed to produce satisfa ctory effects.Therefore,in the search for a solution,we found that a treatment with the gene corresponding to the RGS14414protein in visual area V2,a brain area connected with brain circuits of the ventral stream and the medial temporal lobe,which is crucial for object recognition memory(ORM),can induce enhancement of ORM.In this study,we demonstrated that the same treatment with RGS14414in visual area V2,which is relatively unaffected in neurodegenerative diseases such as Alzheimer s disease,produced longlasting enhancement of ORM in young animals and prevent ORM deficits in rodent models of aging and Alzheimer’s disease.Furthermore,we found that the prevention of memory deficits was mediated through the upregulation of neuronal arbo rization and spine density,as well as an increase in brain-derived neurotrophic factor(BDNF).A knockdown of BDNF gene in RGS14414-treated aging rats and Alzheimer s disease model mice caused complete loss in the upregulation of neuronal structural plasticity and in the prevention of ORM deficits.These findings suggest that BDNF-mediated neuronal structural plasticity in area V2 is crucial in the prevention of memory deficits in RGS14414-treated rodent models of aging and Alzheimer’s disease.Therefore,our findings of RGS14414gene-mediated activation of neuronal circuits in visual area V2 have therapeutic relevance in the treatment of memory deficits.

A recent study published in Science by Krypotou et al.reported the role of an intrinsically disordered region(IDR)in the transcription termination Rho protein from Bacteroides thetaiotaomicron:in response to starvation Rho phase separated,which triggered an increase in Rho activity and expression changes.1 These results demonstrate that a highly conserved protein can acquire new regulatory properties in evolution by gaining an IDR that leads to protein phase separation.

Rock mass structural recognition from drill monitoring technology in underground mining using discontinuity index and machine learning techniques

引用

International Journal of Mining Science and Technology 2023年第5期33卷 555-571页

作者： Alberto Fernández JoséA.Sanchidrián pablo Segarra Santiago Gómez Enming Li Rafael navarro Universidad Politécnica de Madrid–ETSI Minas y Energía Spain Universidad de Salamanca–GIR Charrock Spain

A procedure to recognize individual discontinuities in rock mass from measurement while drilling(MWD)technology is developed,using the binary pattern of structural rock characteristics obtained from in-hole images for calibration.Data from two underground operations with different drilling technology and different rock mass characteristics are considered,which generalizes the application of the methodology to different sites and ensures the full operational integration of MWD data analysis.Two approaches are followed for site-specific structural model building:a discontinuity index(DI)built from variations in MWD parameters,and a machine learning(ML)classifier as function of the drilling parameters and their variability.The prediction ability of the models is quantitatively assessed as the rate of recognition of discontinuities observed in borehole logs.Differences between the parameters involved in the models for each site,and differences in their weights,highlight the site-dependence of the resulting models.The ML approach offers better performance than the classical DI,with recognition rates in the range 89%to 96%.However,the simpler DI still yields fairly accurate results,with recognition rates 70%to 90%.These results validate the adaptive MWD-based methodology as an engineering solution to predict rock structural condition in underground mining operations.

We compared the calling and mating behavior and volatile release of wild males Anastrepha ludens （Loew） with males from 4 mass-reared strains：（i） a stan- dard mass-reared colony （control）, （ii） a genetic sexing strain （Tap-7）, （iii） a colony started from males selected on their survival and mating competitiveness abilities （selected）, and （iv） a hybrid colony started by crossing wild males with control females. Selected and wild males were more competitive, achieving more matings under field cage conditions. Mass-reared strains showed higher percentages of pheromone calling males under field conditions except for Tap-7 males, which showed the highest percentages of pheromone calling males under laboratory cage conditions. For mature males of all strains, field-cage calling behavior increased during the last hour before sunset, with almost a 2 fold increase exhibited by wild males during the last half hour. The highest peak mating activity of the 4 mass-reared strains occurred 30 rain earlier than for wild males. By means of solid phase microextraction （SPME） plus gas chromatography-mass spectrometry （GC- MS）, the composition of volatiles released by males was analyzed and quantified, Wild males emitted significantly less amounts of （E,E）-α-farnesene but emitted significantly more amounts of （E,E）-suspensolide as they aged than mass-reared males. Within the 4 mass-reared strains, Tap-7 released significantly more amounts of （E,E）-α-farnesene and hybrid more of （E,E）-suspensolide. Differences in chemical composition could be ex- plained by the intrinsic characteristics of the strains and the colony management regimes. Characterization of calling behavior and age changes of volatile composition between wild and mass-reared strains could explain the differences in mating competitiveness and may be useful for optimizing the sterile insect technique in A. ludens.

Phosphorus(P) limitation in the coming decades calls for the utilization of alternative fertilizers in agriculture. Struvite is a promising P source, but its potential role as a fertilizer is dependent on different physical, chemical, and biological properties, which are very heterogeneous in soil, complicating the prediction of the best soil conditions for its application. Here, we evaluated the solubility of struvite in soil, its redistribution into P fractions, and its potential abiotic and biotic drivers in 62 globally distributed soils with contrasting properties through an incubation assay. We found that after 40 d, about 35% of struvite P was redistributed into soil fractions more accessible to plants and microbes. Phosphorus redistribution from struvite was driven by a complex suite of soil physical, chemical, and microbial properties as well as environmental factors that varied across soils. Soil texture played a critical role in determining the redistribution of P in struvite-amended soils in soluble(H2O extraction), labile(NaHCO3 extraction), and moderately labile(NaOH extraction) fractions.In addition, the soil solution cation concentration was one of the most important drivers of available struvite-derived P fractions. The great importance of texture and cations in determining struvite-derived P fractions in soil was contrasted with the relatively minor role of pH. At the microbial level, the number of bacterial operational taxonomic units(OTUs) from the unfertilized soils that correlated with struvite-derived P fractions was higher than that of fungi. The number of OTUs that correlated with the struvite-derived soluble P fraction was dominated by fungi, whereas the number of OTUs that correlated with the struvite-derived labile P fraction was dominated by bacteria. Overall, this study provided a predictive framework for the potential use of struvite as a P fertilizer in contrasting soils.

Echocardiographic findings in pulmonary embolism: An important guide for the management of the patient

引用

World Journal of Cardiovascular Diseases 2012年第3期2卷 161-164页

作者： Ronny Cohen pablo Loarte Victor navarro Brooks Mirrer NYU School of Medicine New York USA Woodhull Medical Center New York USA

Echocardiography can be used as an easy, inexpensive, devoid of complications and, for the most part, universally available tool for the risk stratification of patient with acute pulmonary embolism. Because of its low sensibility, an echocardiogram is best indicated in a patient in whom hypotension and or shock are suspected to be due to pulmonary embolism. Pertinent findings in the echocardiogram can justify the use of fibrinolytic therapy. Most common echocar-diographic findings in acute pulmonary embolism are: dilatation of the right ventricle, right ventricular dysfunction in some cases with preservation of the motility of the apex, dilatation of the inferior vena cava with lack of collapse during inspiration flattening of the interventricular septum suggesting right ventricular pressure overload and pulmonary hypertension based on the jet of tricuspid regurgitation if available.
