Variovorax paradoxus F310 inoculation significantly increased shoot P content of both intercropped plants at the three experimental sites compared to the un-inoculated treatment (up to + 48%). It was shown that bacterial inoculation was more efficient at the low-rainfall region than the high-rainfall region. (S)-Glutamic acid The co-inoculation with Sinorhizobium meliloti F42 and Variovorax paradoxus F310 resulted in a significant reduction in fenugreek nodulation and shoot N content. This survey showed the benefits of rhizobial and PGPR inoculation as efficient bio-inoculums to promote the cereal-legume intercropping system and highlights the influence of site-specific environmental factors on Rhizobium-PGPR-plant interactions.

Previous research suggests that sleep polysomnography and EEG endpoints can be used to assess GABAergic activity; however, the impact of GABA

receptor positive allosteric modulators on sleep endpoints remains unclear.

This phase 1 study compared a single dose of ASP8062 (35mg or 70mg), a GABA

receptor positive allosteric modulator, with placebo and paroxetine (40mg).

Healthy adult volunteers were randomized to four treatments (35mg ASP8062, 70mg ASP8062, paroxetine 40mg, or matching placebo), each separated by a 14-day washout. Primary endpoints obtained by polysomnography were time in stage N3 or SWS and time in rapid eye movement (REM) sleep. Secondary endpoints included impact on sleep stages and electroencephalography parameters, pharmacokinetics, nighttime growth hormone (GH), and safety/tolerability.

In 20 randomized volunteers, ASP8062 led to a significant and seemingly dose-dependent increase in SWS over the entire night; this increase was mainly observed during the first third of the night. ASP8062 did not impact time in REM sleep. Paroxetine had no effect on SWS but produced a significant reduction in time spent in REM sleep. A dose-dependent trend in increased GH release was also observed with ASP8062. Headache and nausea were the most commonly reported treatment-emergent adverse events (TEAEs) for ASP8062; most TEAEs were mild in severity.

Single-dose ASP8062 (35 and 70mg) appeared to result in CNS penetration and enhanced GABAergic activity as measured by increases in slow-wave sleep and growth hormone release.

Cyclic tensile stress (CTS) can stimulate stem cell osteogenic differentiation. The present study explored the mechanism of CTS in hPDLSC osteogenic differentiation. The hPDLSCs of the 4th passage were selected. hPDLSCs were subjected to CTS with deformation of 10% elongation at 0.5 Hz for 1, 4, 8, 12 and 24 h. ALP activity and staining, ARS staining and detection of expressions of osteogenesis-related genes (RUNX2, OPN, Sp7 and OCN) were used to assess hPDLSC osteogenic differentiation ability. microRNA (miR)-129-5p and BMP2 expression and p-Smad1/5 level were detected under CTS stimulation. The binding relationship between miR-129-5p and BMP2 was predicted and verified. The osteogenic differentiation ability of CTS-treated hPDLSCs was evaluated after intervention of miR-129-5p and BMP2. link2 CTS induced hPDLSC osteogenic differentiation, as manifested by increased ALP activities, osteogenesis-related gene expressions and mineralized nodules, together with positive ALP staining. CTS inhibited miR-129-5p expression, and promoted BMP2 expression and p-Smad1/5 level in hPDLSCs. miR-129-5p targeted BMP2. Overexpressed miR-129-5p or silenced BMP2 prevented hPDLSC osteogenic differentiation ability. We demonstrated that CTS inhibited miR-129-5p expression, and then activated the BMP2/Smad pathway, thereby showing stimulative effects on hPDLSC osteogenic differentiation.

To prospectively evaluate the effect of benzalkonium chloride (BAK)-preserved latanoprost on ocular surface damage and identify the associated risk factors among treatment-naive glaucoma patients.

The basal Schirmer's test results, corneal Oxford staining score, non-invasive keratograph tear-breakup time, oculus hyperemia index score (objective metrics), and ocular surface disease index (OSDI) questionnaire (subjective metric) were evaluated at baseline, 1month, and 4months after receiving latanoprost eye drops. Associated risk factors were assessed by multivariate linear regression.

Seventy-four eyes (44 patients) were enrolled. Basal Schirmer's test tear-flow and Oxford scores gradually deteriorated (β = -0.14, P = 0.001 and β = 0.1, P < 0.001, respectively). The percentage of unstable tear-film (breakup time < 10s) increased significantly at 4months (6.21% vs 9.11%, P = 0.042). Hyperemic scores increased significantly at 1month and normalized at 4months (P = 0.01 and P = 0.16, respectively); total OSDI scores tended to improve (β = -0.76, P = 0.06). Older age was associated with additional corneal Oxford staining (P = 0.005); female sex was associated with increased unstable tear-film scores (P = 0.01). Artificial tear use was associated with a smaller decrease in basal Schirmer's test values (P = 0.01) and a smaller increase in unstable tear-film scores (P = 0.02).

Preserved latanoprost eye drops affected ocular surface changes in glaucoma patients through decreased basal tear secretion. Artificial tears represent an early intervention in vulnerable glaucoma patients with reduced tear secretion and impaired tear-film stability.

Studies have pivoted on the position of microRNAs (miRNAs) in knee osteoarthritis (KOA) but not the more specific function of miR-199-3p. Thus, this study is to uncover the mechanism of miR-199-3p in KOA.

Rats KOA models were established by modified Hulth method. miR-199-3p expression was observed in cartilage of KOA rats. The binding sites of miR-199-3p were predicted by bioinformatics analysis and the potential interaction between DNA methyltransferase 3A (DNMT3A) and miR-199-3p was verified by dual-luciferase reporter gene assay. Rats were injected with miR-199-3p agomir or antagomir and DNMT3A siRNA into the knee joint. Inflammatory response factors in serum and cartilage tissues, cell apoptosis, and pathological status of cartilage tissues were detected. Chondrocytes were isolated from KOA cartilages and treated with miR-199-3p mimicorinhibitor and DNMT3A siRNA. Chondrocyte proliferation and apoptosis were detected.

miR-199-3p expression was suppressed in cartilage of KOA rats. Dual-luciferase reporter gene assay proved that a miR-199-3p-binding site was located in the 3'UTR of DNMT3A mRNA. Inflammation, chondrocyte apoptosis and cartilage pathological changes were improved by miR-199-3p agomir but aggravated by miR-199-3p antagomir. The effects of miR-199-3p antagomir on KOA rats were partially reversed by DNMT3A siRNA. miR-199-3p mimic or DNMT3A siRNA decreased KOA chondrocytes apoptosis and promoted proliferation. miR-199-3p inhibitor showed the opposite functions to miR-199-3p mimic. The effects of miR-199-3p inhibitor on chondrocytes were reversed by DNMT3A siRNA.

This study highlights that miR-199-3p up-regulation or down-regulation of DNMT3A induces chondrocyte proliferation and inhibits apoptosis in KOA, which may widen our eyes to treat patients with KOA.

Twenty-four women and 24 men performed a visual discrimination task of upright or inverted images of female or male bodies and faces (Experiment 1) and objects (Experiment 2). In Experiment 1, both groups of women and men showed comparable abilities in the discrimination of upright and inverted bodies and faces. However, the gender of the human stimuli yielded different effects on participants' performance, so that female faces, and male bodies appeared to be processed less configurally than female bodies and male faces, respectively. Interestingly, the reduction of configural processing for male bodies was significantly predicted by participants' Body Mass Index (BMI) and their level of internalization of muscularity. Our findings suggest that configural visual processing of bodies and faces in women and men may be linked to a selective attention to detail needed for discriminating salient physical (perhaps sexual) cues of conspecifics. Importantly, BMI and muscularity internalization of beauty ideals may also play a crucial role in this mechanism.Variation in GC content is assumed to correlate with various processes, including mutation biases, recombination, and environmental parameters. To date, most genomic studies exploring the evolution of GC content have focused on nuclear genomes, but relatively few have concentrated on organelle genomes. We explored the mechanisms maintaining the GC content in angiosperm plastomes, with a particular focus on the hypothesis of phylogenetic dependence and the correlation with deletion mutations. We measured three genetic traits, namely, GC content, A/T tracts, and G/C tracts, in the coding region of plastid genomes for 1382 angiosperm species representing 350 families and 64 orders, and tested the phylogenetic signal. Then, we performed correlation analyses and revealed the variation in evolutionary rate of selected traits using RRphylo. The plastid GC content in the coding region varied from 28.10% to 43.20% across angiosperms, with a few non-photosynthetic species showing highly reduced values, highlighting the significance of functional constraints. We found strong phylogenetic signal in A/T tracts, but weak ones in GC content and G/C tracts, indicating adaptive potential. link3 GC content was positively and negatively correlated with G/C and A/T tracts, respectively, suggesting a trade-off between these two deletion events. GC content evolved at various rates across the phylogeny, with significant increases in monocots and Lamiids, and a decrease in Fabids, implying the effects of some other factors. We hypothesize that variation in plastid GC content might be a mixed strategy of species to optimize fitness in fluctuating climates, partly through influencing the trade-off between AT → GC and GC → AT mutations.Pea (Pisum sativum L.), a cool-season legume crop grown in more than 85 countries, is the second most important grain legume and one of the major green vegetables in the world. While pea was historically studied as the genetic model leading to the discovery of the laws of genetics, pea research has lagged behind that of other major legumes in the genomics era, due to its large and complex genome. The evolving climate change and growing population have posed grand challenges to the objective of feeding the world, making it essential to invest research efforts to develop multi-omics resources and advanced breeding tools to support fast and continuous development of improved pea varieties. Recently, the pea researchers have achieved key milestones in omics and molecular breeding. The present review provides an overview of the recent important progress including the development of genetic resource databases, high-throughput genotyping assays, reference genome, genes/QTLs responsible for important traits, transcriptomic, proteomic, and phenomic atlases of various tissues under different conditions.
