Background: Pharyngeal and anorectal reservoirs of gonorrhea(GC) and chlamydia(CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease(STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.S. ***: We recruited servicewomen stationed in San Diego, California, between the ages of 18 and 25 who presented for an annual physical exam between January and September, 2017. Nucleic acid amplification testing was performed on swabs collected at endocervical, oropharyngeal and anorectal sites to assess the presence of GC/CT. An anonymous behavioral questionnaire was also administered to characterize sexual risk. Descriptive statistics were used to compare women with and without a prior history of any sexually transmitted infection(STI)(self-report) along with a current GC/CT diagnosis. This study was approved by the Institutional Review Board of the Uniformed Services University of Health ***: Of the 75 patients who were approached, 60 subjects were enrolled in the study, including white 20(33.3%), black/African American 18(31.0%), Hispanic/Latina 13(21.7%) and Asian/Pacific Islander 9(15.5%) women. Among all the women, six(10.0%) were diagnosed with CT infection, all via endocervical exam. Of these, five(8.3%) had concurrent anorectal infection, including two cases(3.3%) accompanied by pharyngeal infection. Of the subjects, 15(25.0%) reported anal intercourse in their most recent sexual encounter, most of which was condomless(13/15, 86.7%). A high number of women who reported sex with a casual male partner(19/45, 42.2%) reported rarely or never using condoms;last, 41.7% consuming at least 3 drinks on a typical drinking day, and one-third of the reported drinking more than once

Background: Long-term survival in acute coronary syndrome has increased steadily in the last decades. Follow-up studies developed in this patient clearly reveal that they are at risk of suffering a new event, placing them in a new stage, secondary prevention. Assuming this increased risk, the control target of their cardiovascular risk factors become more ambitious. In this field, control of Cholesterol levels, particularly LDL-C, has arisen as a priority objective in patients with coronary arterial disease. In this sense, management of dyslipidemia guidelines, recently recognises the role of functional food, highlighting among them is the Red Yeast Rice (RYR). The aim of the study is to establish the potential role of functional food, in secondary prevention, while determining its additional capacity to reduce LDL-C in patients that despite optimal classic treatment (maximum tolerated dose of stain plus Ezetimibe) is still out of control objectives. Results and Discussion: 88 patients were included and after 3 months of tr

We characterized the transcriptomic response of transgenic plants carrying a mitochondrial dysfunction induced by the expression of the unedited form of the ATP synthase subunit 9. The u-ATP9 transgene driven by A9 and APETALA3 promoters induce mitochondrial dysfunction revealed by a decrease in both oxygen uptake and adenine nucleo- tides （ATP, ADP） levels without changes in the ATIP/ADP ratio. Furthermore, we measured an increase in ROS accumulation and a decrease in glutathione and ascorbate levels with a concomitant oxidative stress response. The transcriptome analysis of young Arabidopsis flowers, validated by qRT-PCR and enzymatic or functional tests, showed dramatic changes in u-ATP9 plants. Both lines display a modification in the expression of various genes involved in carbon, lipid, and cell wall metabolism, suggesting that an important metabolic readjustment occurs in plants with a mitochondrial dysfunction. Interestingly, transcript levels involved in mitochondrial respiration, protein synthesis, and degradation are affected. More- over, the levels of several mRNAs encoding for transcription factors and DNA binding proteins were also changed. Some of them are involved in stress and hormone responses, suggesting that several signaling pathways overlap. Indeed, the tran- scriptome data revealed that the mitochondrial dysfunction dramatically alters the expression of genes involved in signaling pathways, including those related to ethylene, absicic acid, and auxin signal transduction. Our data suggest that the mitochondrial dysfunction model used in this report may be useful to uncover the retrograde signaling mechanism between the nucleus and mitochondria in plant cells.

El Soplao outcrop, an Early Cretaceous amber deposit recently discovered in northern Spain （Cantabria）, has been shown to be the largest site of amber with arthropod inclusions that has been found in Spain so far. Relevant data provided herein for biogeochemistry of the amber, palynology, taphonomy and arthropod bioinclusions complement those previously published. This set of data suggests at least two botanical sources for the amber of El Soplao deposit. The first （type A amber） strongly supports a source related to Cheirolepidiaceae, and the second （type B amber） shows non-specific conifer biomarkers. Comparison of molecular composition of type A amber with Frenelopsis leaves （Cheirolepidiaceae） strongly suggests a biochemical affinity and a common botanical origin. A preliminary palynological study indicates a regional high taxonomical diversity, mainly of pteridophyte spores and gymnosperm pollen grains. According to the preliminary palynological data, the region was inhabited by conifer forests adapted to a dry season under a subtropical climate. The abundant charcoalified wood associated with the amber in the same beds is evidence of paleofires that most likely promoted both the resin production and an intensive erosion of the litter, and subsequent great accumulation of amber plus plant cuticles. In addition, for the first time in the fossil record, charcoalified plant fibers as bioinclnsions in amber are reported. Other relevant taphonomic data are the exceptional presence of serpulids and bryozoans on the surfaces of some amber pieces indicating both a long exposure on marine or brackish-water and a mixed assemblage of amber. Lastly, new findings of insect bioiuclusions, some of them uncommon in the fossil record or showing remarkable adaptations, are reported. In conclusion, a documented scenario for the origin of the El Soplao amber outcrop is provided.
