Bread wheat(Triticum aestivum),during its evolution,experienced severe genetic bottlenecks due to polyploidization and domestication.Then,breeding programs,triggered mainly by the Green revolution within a narrow range of breeders'preferred parents,while increasing the global wheat productivity,produced a further and evident reduction of genetic diversity.A clear picture of the impact of domestication and breeding on genetic diversity was achieved after recent studies that highlight loci subjected to past or ongoing selection,described as selection signatures or selective sweeps.

Polyploidy is characterized by the presence of two or more complete sets of chromosomes coming from intraspecies whole-genome duplication(i.e.,autopolyploidy)or from hybridization between distinct but related species(i.e.,allopolyploidy).Poly-ploidization is a driving force in the evolution of higher plants,most of the plant species have experienced ancient or recent genome duplication events that have led to several genome modifications,such as chromosomal reorganization,gene conversion,sub-genome dominance,alteration of gene expression patterns,and expansion/contraction of some gene families.

Multimedia content,user mobility and heterogeneous client devices require novel systems that are able to support ubiquitous access to the Web resources.In this scenario,solutions that combine flexibility,efficiency and scalability in offering edge services for ubiquitous access are needed.We propose an original intermediary framework,namely Scalable Intermediary Software Infrastructure （SISI）,which is able to dynamically compose edge services on the basis of user preferences and device characteristics.The SISI framework exploits a per-user profiling mechanism,where each user can initially set his/her personal preferences through a simple Web interface,and the system is then able to compose at run-time the necessary components.The basic framework can be enriched through new edge services that can be easily implemented through a programming model based on APIs and internal functions.Our experiments demonstrate that flexibility and edge service composition do not affect the system performance.We show that this framework is able to chain multiple edge services and to guarantee stable performance.

Intimate partner violence has been recognized as a serious public health issue.Exposure to violence contributes to the genesis of,and exacerbates,mental health conditions,and existing mental health problems increase vulnerability to partner violence,a loop that imprisons victims and perpetuates the abuse.a.recently described phenomenon is when male violence against females occurs within intimate relationships during youth,and it is termed adolescent or teen dating violence.In this narrative review,factors associated with intimate partner violence and consequences of exposure of children to parental domestic violence are discussed,along with possible intensification of violence against women with the spread of coronavirus disease 2019 pandemic and subsequent lockdown.Intervention programs with a multicomponent approach involving many health care settings and research have a pivotal role in developing additional strategies for addressing violence and to provide tailored interventions to victims.Prevention policy with a particular attention on healthy child and adolescent development is mandatory in the struggle against all forms of violence.

AIM:To evaluate whether FDG-positron emission tomography(PET)/computed tomography(CT)may be an accurate technique in the assessment of the T stage in patients with colorectal cancer.METHODS:Thirty four consecutive patients(20 men and 14 women;mean age:63 years)with a histologically proven diagnosis of colorectal adenocarcinoma and scheduled for surgery in our hospital were enrolled in this study.All patients underwent FDG-PET/CT preoperatively.The primary tumor site and extent were evaluated on PET/CT images.Colorectal wall invasion was analysed according to a modified T classification that considers only three stages(≤T2,T3,T4).Assessment of accuracy was carried out using 95%confidence intervals for T.reSULTS:Thirty five/37(94.6%)adenocarcinomas were identified and correctly located on PET/CT images.PET/CT correctly staged the T of 33/35 lesions identified showing an accuracy of 94.3%(95%CI:87%-100%).All T1,T3 and T4 lesions were correctly staged,while two T2 neoplasms were overstated as T3.CONCLUSION:Our data suggest that FDG-PET/CT may be an accurate modality for identifying primary tumor and defining its local extent in patients with colorectal cancer.

BACKGROUND Interstitial cystitis/bladder pain syndrome(IC/BPS)is an at least 6-mo noninfectious bladder inflammation of unknown origin characterized by chronic suprapubic,abdominal,and/or pelvic pain.Although the term cystitis suggests an inflammatory or infectious origin,no definite cause has been identified.It occurs in both sexes,but women are twice as much affected.AIM To systematically review evidence of psychiatric/psychological changes in persons with IC/BPS.METHODS Hypothesizing that particular psychological characteristics could underpin IC/BPS,we investigated in three databases the presence of psychiatric symptoms and/or disorders and/or psychological characteristics in patients with IC/BPS using the following strategy:("interstitial cystitis"OR"bladder pain syndrome")AND("mood disorder"OR depressive OR antidepressant OR depression OR depressed OR hyperthymic OR mania OR manic OR rapid cyclasterisk OR dysthymiasterisk OR dysphoriasterisk).reSULTS On September 27,2023,the PubMed search produced 223 articles,CINAHL 62,and the combined PsycLIT/PsycARTICLES/PsycINFO/Psychology and Behavioral Sciences Collection search 36.Search on ClinicalTrials.gov produced 14 studies,of which none had available data.Eligible were peer-reviewed articles reporting psychiatric/psychological symptoms in patients with IC/BPS,i.e.63 articles spanning from 2000 to October 2023.These studies identified depression and anxiety problems in the IC/BPS population,along with sleep problems and the tendency to catastrophizing.CONCLUSION Psychotherapies targeting catastrophizing and life stress emotional awareness and expression reduced perceived pain in women with IC/BPS.Such concepts should be considered when implementing treatments aimed at reducing IC/BPS-related pain.

Post-transcriptional gene silencing mediated by microRNAs(miRNAs)modulates numerous developmental and stress response pathways.For the last two decades,HASTY(HST),the ortholog of human EXPORTIN 5,was considered to be a candidate protein that exports plant miRNAs from the nucleus to the cytoplasm.Here,we report that HST functions in the miRNA pathway independent of its cargo-exporting activity in Arabidopsis.We found that Arabidopsis mutants with impa.red HST shuttling exhibit normal subcellular distribution of miRNAs.Interestingly,protein-protein interaction and microscopy assays showed that HST directly interacts with the microprocessor core component DCL1 through its N-terminal domain.Moreover,mass spectrometry analysis revealed that HST also interacts independently of its N-terminal domain with the mediator complex subunit MED37.Further experiments revealed that HST could act as a scaffold to facilitate the recruitment of DCL1 to genomic MIRNA loci by stabilizing the DCL1-MED37 complex,which in turn promotes the transcription and proper processing of primary miRNA transcripts(primiRNAs).Taken together,these results suggest that HST is likely associated with the formation of the miRNA biogenesis complex at MIRNA genes,promoting the transcription and processing of primiRNAs rather than the direct export of processed miRNAs from the nucleus.

Background:The usefulness of C-reactive protein(CRP)as a non-specific marker of inflammation during pregnancy and lactation is unclear in impoverished populations where co-existing infections and vitamin deficiencies are common.Methods:This cross-sectional study in Panama.recruited 120 pregnant and 99 lactating Ngäbe-Buglewomen from 14 communities in rural Panama.Obstetric history,indoor wood smoke exposure,fieldwork,BMI,vitamins A,B_(12),D,and folic acid,and inflammation markers(CRP,neutrophil/lymphocyte ratio(NLR),plateletcrit and cytokines)were measured.Multiple regressions explored both associations of CRP with other inflammatory markers and associations of CRP and elevated CRP based on trimester-specific cut-offs with maternal factors,infections and vitamin deficiencies.results:CRP was higher in pregnancy(51.4±4.7 nmol/L)than lactation(27.8±3.5 nmol/L)and was elevated above trimester specific cut-offs in 21%of pregnant and 30%of lactating women.Vitamin deficiencies were common(vitamin A 29.6%;vitamin D 68.5%;vitamin B1268%;folic acid 25.5%)and over 50%of women had two or more concurrent deficiencies as well as multiple infections.Multiple regression models highlighted differences in variables associated with CRP between pregnancy and lactation.In pregnancy,CRP was positively associated with greater indoor wood smoke exposure,caries and hookworm and negatively associated with Ascaris and vaginal Lactobacillus and Bacteroides/Gardnerella scores.Consistent with this,greater wood smoke exposure,caries as well as higher diplococcal infection score increased the odds of trimester-elevated CRP concentrations whereas longer gestational age lowered the likelihood of a trimester-elevated CRP.During lactation,folic acid deficiency was associated with higher CRP whereas parity,number of eosinophils and Mobiluncus score were associated with lower CRP.Also,a higher BMI and Trichomonas vaginalis score increased the likelihood of an elevated CRP whereas higher parity and number of eosinophils were associated with lower like
