The results of the present study indicate that overexpression of EsPHT1;1 can efficiently enhance the growth and reproductive performance of both Arabidopsis and soybean plants challenged by low P stress, which results confirm the important role of PHT1;1 in dealing with Pi deficiency.At the end of 2019, a new coronavirus disease, COVID-19, emerged and quickly spread around the world. Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2), the causative virus of this disease, belongs to the β-coronavirus family, together with SARS and middle east respiratory syndrome, and has similar biological characteristics to these viruses. For obstetricians, the susceptibility and prognoses of pregnant women and the effects of the infection on the fetus have been the focus of attention; however, at present, the seriousness of the disease in pregnant women is not apparent, and COVID-19 does not increase the rate of miscarriage, stillbirth, preterm labor or teratogenicity. Even so, carriers might transmit SARS-CoV-2 to pregnant women. Thus, we must keep in mind that all medical personnel must understand and maintain standard precautions in their clinical and laboratory practices.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causing coronavirus disease 2019 (COVID-19) is the biggest pandemic of our lifetime to date. No effective treatment is yet in sight for this catastrophic illness. [https://www.selleckchem.com/products/ml324.html selleckchem] Several antiviral agents and vaccines are in clinical trials, and drug repurposings as immediate and alternative choices are also under consideration. Immunomodulatory agents like hydroxychloroquine (HCQ) as well as biological disease-modifying anti-rheumatic drugs (bDMARDs) such as tocilizumab and anakinra received worldwide attention for treatment of critical patients with COVID-19. This is of interest to rheumatologists, who are well versed with rational use of these agents. This brief review addresses the understandings of some of the common immunopathogenetic mechanisms in the context of autoimmune rheumatic diseases like systemic lupus erythematosus (SLE) and COVID-19. Apart from demographic comparisons, the role of type I interferons (IFN), presence of antiphospholipid antibodies and finally mechanism of action of HCQ in both the scenarios are discussed here. High risks for fatal disease in COVID-19 include older age, metabolic syndrome, male gender, and individuals who develop delayed type I IFN response. HCQ acts by different mechanisms including prevention of cellular entry of SARS-CoV-2 and inhibition of type I IFN signaling. Recent controversies regarding efficacy of HCQ in management of COVID-19 warrant more studies in that direction. Autoantibodies were also reported in severe acute respiratory syndrome (SARS) as well as in COVID-19. Rheumatologists need to wait and see whether SARS-CoV-2 infection triggers development of autoimmunity in patients with COVID-19 infection in the long run.<br />Perceptions of peer alcohol use have a strong influence on college students' personal alcohol consumption. Common strategies for measuring students' perceptions of peer alcohol use rely on global student body questions (e.g. 'typical' student use), which overlook the true social contexts of college students. Simply put, persons most likely to influence an individual's behaviour are their closest, most proximal peers. Our objective was to compare whether social norms measures or network measures of peer alcohol use better assess participant alcohol use. Specifically, we compared (i) perceptions of the 'typical' student's drinking behaviours; versus (ii) egocentric social network measures, in which respondent's report perceptions of the drinking behaviours of personally identified peers.<br />Three hundred and nine college students reported demographics, personal alcohol use and global perceptions of peer alcohol use. Egocentric network composition was calculated using E-Net. Descriptive statistics and hierarchie of alcohol use among college students.<br />To evaluate left ventricular (LV) dysfunction in patients with rheumatoid arthritis (RA) and to determine the impact of biological treatment on LV function in these patients using global circumferential strain (GCS), global longitudinal strain (GLS) and global radial strain (GRS) values assessed by feature tracking cardiac magnetic resonance (FT-CMR) imaging.<br />Eighty patients with RA and 20 controls without cardiovascular disease underwent non-contrast CMR imaging. Patients with RA received conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or biologic DMARDs (bDMARDs). Global strains were calculated in 16 LV segments.<br />No significant differences in cardiovascular risk factors were found between the RA group and controls. GCS was 21% lower in the RA group compared with controls (P&lt; 0.001) and was 14% lower in the csDMARDs group compared with the bDMARDs group (P=0.002), whereas, there was no significant difference in GLS and GRS between the RA group and the controls. In regard to strain rates, diastolic GCS and GRS rates were significantly lower in the RA group (P&lt;0.001, 0.011, respectively). In univariate analyses, GCS was significantly associated with the Simplified Disease Activity Index, bDMARDs, swollen joint count, anti-cyclic citrullinated peptides antibodies and matrix metalloproteinase-3, but in multivariable analysis, only bDMARDs was significantly associated with GCS (P=0.021).<br />Global circumferential strain, GLS and GRS assessed by FT-CMR can reveal subclinical LV dysfunction in patients with RA. Furthermore, they can be used to determine the normalization of LV regional dysfunction induced by bDMARDs possibly related to disease activity reduction.<br />Global circumferential strain, GLS and GRS assessed by FT-CMR can reveal subclinical LV dysfunction in patients with RA.

Mossy fibre sprouting (MFS) and synaptic plasticity promote epileptogenesis. Overexpression of repulsive guidance molecule a (RGMa) prevents epileptogenesis by inhibiting MFS. However, other aspects underlying the RGMa regulatory process of epileptogenesis have not been elucidated. We studied whether RGMa could be modulated by microRNAs and regulated RhoA in epileptogenesis. Using microRNA databases, we selected four miRNAs as potential candidates. We further experimentally confirmed miR-20a-5p as a RGMa upstream regulator. Then, in vitro, by manipulating miR-20a-5p and RGMa, we investigated the regulatory relationship between miR-20a-5p, RGMa and RhoA, and the effects of this pathway on neuronal morphology. Finally, in the epilepsy animal model, we determined whether the miR-20a-5p-RGMa-RhoA pathway influenced MFS and synaptic plasticity and then modified epileptogenesis. Our results showed that miR-20a-5p regulated RGMa and that RGMa regulated RhoA in vitro. Furthermore, in primary hippocampal neurons, the miR-20a-5p-RGMa-RhoA pathway regulated axonal growth and neuronal branching; in the PTZ-induced epilepsy model, silencing miR-20a-5p prevented epileptogenesis through RGMa-RhoA-mediated synaptic plasticity but did not change MFS.
