Diseases caused by phytopathogenic bacteria are responsible for significant economic losses, and these bacteria spread through diverse pathways including waterways and industrial wastes. It is therefore of interest to develop potent methods for their eradication. Here, antibacterial properties of direct current atmospheric pressure glow discharge (dc-APGD) generated in contact with flowing bacterial suspensions were examined against five species of phytopathogens. Complete eradication of Clavibacter michiganensis subsp...

Altitude is a confounding factor within the Athlete's Biological Passport (ABP) due, in part, to the plasma volume (PV) response to hypoxia. Here, a newly developed PV blood test is applied to assess the possible efficacy of reducing the influence of PV on the volumetric ABP markers; hemoglobin concentration ([Hb]) and the OFF-score. Endurance athletes (n=34) completed a 21 night simulated live high: train low protocol (14h.d-1 at 3000m). Bloods were collected twice pre-altitude, at days 3, 8 and 15 at altitude and 1, 7, 21 and 42 days post-altitude...

To broaden the absorption spectrum, improve intramolecular electronic push-pull balance capability, enhance electron transfer and promote the photovoltaic performances of dye sensitizers, four new polymeric metal complex dyes (PBDTT-PhenCd, PBDTT-PhenCu, PPV-PhenCd and PPV-PhenCu) with donor-acceptor-π-bridge-acceptor (D-A-π-A) structure were designed and synthesized. These dyes, for the first time, used the complexes of Cd(ii) or Cu(ii) with phenanthroline as auxiliary electron acceptors (A) instead of organic electron withdrawing groups and adopted thienylbenzo [1,2-b:4,5-b'] dithiophene (BDTT) or hydroquinone (PV) derivatives as electron donors (D) and 8-quinolinol derivatives as π bridge and acceptors (A)...

Aggrecan, a chondroitin sulfate (CS) proteoglycan, forms lattice-like extracellular matrix structures called perineuronal nets (PNNs). Neocortical PNNs primarily ensheath parvalbumin-expressing inhibitory neurons (parvalbumin, PV cells) late in brain development. Emerging evidence indicates that PNNs promote the maturation of PV cells by enhancing the incorporation of homeobox protein Otx2 and regulating experience-dependent neural plasticity. Wisteria floribunda agglutinin (WFA), an N-acetylgalactosamine-specific plant lectin, binds to the CS chains of aggrecan and has been widely used to visualize PNNs...

BACKGROUND: Breeding two-line hybrid rice with disease resistance is an effective approach to stabilize rice yield in commercial rice production of China. RESULTS: We improved the blast and bacterial blight resistance of Guangzhan63-4S, an elite photoperiod- and thermo-sensitive male sterile (P/TGMS) line widely used in two-line hybrid rice, by introducing the R genes Pi2 and Xa7 conferring resistance to rice blast and bacterial blight, respectively. Through the backcrossing and gene pyramiding breeding coupled with molecular marker-assisted selection, a new P/TGMS line Hua1228S carrying Pi2, Xa7, and tms5 was developed...

In this research, we investigated the profile and bioactivities of quinazoline alkaloids, a class of natural products boasting multiple bioactivities, from the unripe fruit of Evodia rutaecarpa (Juss.) Benth. Three new quinazoline alkaloids, evodiamide A (1), evodiamide B (2), and evodiamide C (3), as well as eight known quinazolines, were isolated from the MeOH extract of E. rutaecarpa. The new compounds are rare quinazolinedione derivatives with linked heterocyclic nuclei. Among these quinazolines, rhetsinine (8) showed potential as a pesticide and exhibited excellent inhibition against Xanthomonas oryzae pv...

The overexpression of RXam1 leads to a reduction in bacterial growth of XamCIO136, suggesting that RXam1 might be implicated in strain-specific resistance. Cassava bacterial blight (CBB) caused by Xanthomonas axonopodis pv. manihotis (Xam) is a prevalent disease in all regions, where cassava is cultivated. CBB is a foliar and vascular disease usually controlled through host resistance. Previous studies have found QTLs explaining resistance to several Xam strains. Interestingly, one QTL called XM5 that explained 13% of resistance to XamCIO136 was associated with a similar fragment of the rice Xa21-resistance gene called PCR250...

Autism is a neurodevelopmental disorder characterized by disruptions in three core behavioral domains: deficits in social interaction, impairments in communication, and repetitive and stereotyped patterns of behavior or thought. There are currently no drugs available for the treatment of the core symptoms of ASD and drugs that target comorbid symptoms often have serious adverse side effects, suggesting an urgent need for new therapeutic strategies. The neurobiology of autism is complex, but converging evidence suggests that ASD involves disruptions in the inhibitory GABAergic neurotransmitter system...

BACKGROUND: An effective catheter ablation strategy, beyond pulmonary vein isolation (PVI), for persistent atrial fibrillation (AF) is necessary. Pulmonary vein (PV)-reconduction also causes recurrent atrial tachyarrhythmias. The effect of the PVI and additional effect of a superior vena cava (SVC) isolation (SVCI) was strictly evaluated. METHODS: Seventy consecutive patients with persistent AF who underwent a strict sequential ablation strategy targeting the PVs and SVC were included in this study...

Plant immune responses activated through perception of microbe-associated molecular patterns, leading to pattern-triggered immunity (PTI), are tightly regulated. This results in low immune responses in the absence of pathogens and rapid return to the resting state following an activation event. Here, we show that two CALMODULIN-LIKE genes, CML46 and CML47, negatively regulate salicylic acid (SA) accumulation and immunity. The double mutant cml46 cml47 is highly resistant to Pseudomonas syringae pv. maculicola (Pma)...

Rituximab and intravenous immunoglobulin [IVIg] have recently emerged as effective treatments for pemphigus refractory to corticosteroids [CS]. This case series sought to compare the clinical, serologic,and adverse effects of CS, IVIg, and rituximab in patients with pemphigus. A retrospective review of 63 patients with pemphigus vulgaris (PV), pemphigus foliaceus (PF), or paraneoplastic pemphigus (PNP)was performed. Clinical remission (CR), serologic remission (SR), and adverse effects were evaluated. Three study groups were compared: patients treated with systemic CS, refractory patients treated withIVIg, and refractory patients treated with rituximab...
