Lucila Andrea Acevedo, Linda K Nicholson
Cyclophilins are enzymes that catalyze the isomerization of a prolyl-peptide bond and are found in both prokaryotes and eukaryotes. LRT2 (also known as OsCYP2) is a cyclophilin in rice (Oryza sativa), that has importance in lateral root development and stress tolerance. LRT2 is 172 amino acids long and has a molecular weight of 18.3 kDa. Here, we report the backbone and sidechain resonance assignments of 1H, 13C, 15N in the LRT2 protein using several 2D and 3D heteronuclear NMR experiments at pH 6.7 and 298 K...

Soil contamination with heavy metals is threatening the food security around the globe. Chromium (Cr) contamination results in poor quality and reduction in yield of crops. The present research was performed to figure out the Cr toxicity in sunflower and the ameliorative role of 5-aminolevulinic acid (ALA) as a plant growth regulator. The sunflower (FH-614) was grown under increasing concentration of Cr (0, 5, 10 and 20mgkg-1) alone and/or in combination with 5-ALA (0, 10 and 20mgL-1). Results showed that Cr suppressed the overall growth, biomass, gas exchange attributes and chlorophyll content of sunflower plants...

Biodiesel is considered an important renewable energy source but still there is some controversy about its environmental toxicity, especially to aquatic life. In our study, the toxicity of water soluble fraction of biodiesel was evaluated in relatively low concentrations using a battery of bioassays: Vibrio fischeri bioluminescence inhibition, Sinapis alba root growth inhibition, Daphnia magna immobilization, boar semen live/dead ratio and DNA fragmentation and Unio pictorum micronucleus test. While the S. alba test indicated nutritive (stimulating) effect of the sample, the biodiesel exerted toxic effect in the aquatic tests...

Nitrogen is required for optimal plant growth, especially in young organs such as secondary axes (axes II) after axillary bud outgrowth. Several studies have shown an increase of nitrogen concentration in xylem sap concomitantly with bud outgrowth, but the relation between nitrogen, sugars and plant hormones in axis II still remains unclear. We investigated in Rosa hybrida the involvement of nitrogen nutrition in axis II elongation in relation with sugars and cytokinins using 15N-labeled nitrate and sugars, amino acids and cytokinin quantifications...

The aim of this study was to investigate the analgesic effect of the spirocyclopiperazinium salt compound LXM-15 by intragastric administration in thermal and chemical pain models and further to elucidate the possible molecular mechanisms. The results showed that LXM-15 exerted significant antinociception in hot-plate test, formalin test and acetic acid writhing test. Western blot analysis showed that LXM-15 significantly reduced the upregulation of phosphorylation of calcium/calmodulin -dependent protein kinaseⅡα (CaMKIIα) and cAMP response element-binding protein (CREB), and further decreased the elevation of calcitonin gene related peptide (CGRP) in the dorsal root ganglion (DRG) and spinal cord in mice...

Aluminum (Al) stress alters nitric oxide (NO) and induces programmed cell death (PCD) in plants. Recent study has shown that NO inhibits Al-induced PCD. However, the mechanism of NO inhibiting Al-induced PCD has not been revealed yet. Here, we investigated the behavior of mitochondria during Al-induced PCD suppressed by NO in peanut. Seedlings of peanut was grown hydroponically in a controllable growth room. The mitochondrial physiological parameters were determined spectrophotometrically. The expression of AhANT and AhHsp70 was determined by quantitative RT-PCR...

Achyranthes bidentata is an important Traditional Chinese Medicine for the treatment of osteoporosis. In this study, A. bidentata polysaccharide (ABPB), which was extracted with alkali from the root of A. bidentata at room temperature, significantly increased the bone mineral density, bone mineral content, trabecular thickness, trabecular number and biomechanical properties of ovariectomized (OVX) rats, indicating that ABPB had prominent curative effects on osteoporosis in OVX rats. A novel polysaccharide (ABPB-3) was purified from ABPB, and its structure was characterized as a repeating unit consisting of →4)-α-d-GalpA-(1→, →2,4)-α-l-Rhap-(1→, →5)-α-l-Araf-(1→, →2,3,5)-α-l-Araf-(1→, →3)-β-d-Galp-(1→, →3,4,6)-β-d-Galp-(1→, terminated with α-l-Araf, α-l-Rhap and β-d-Galp...

Patients suffering from Spinal Cord Injury (SCI) still have a dismal prognosis. Despite all the efforts developed in this area, currently there are no effective treatments. Therefore, cell therapies have been proposed as a viable alternative to the current treatments employed. Adipose tissue-derived Stem Cells (ASCs) and Olfactory Ensheathing Cells (OECs) have been used with promising results in different models of SCI, namely due to the regenerative properties of the secretome of the first, and the guidance capability of the second...

Poor insight in schizophrenia is prevalent across cultures and phases of illness. In this review, we examine the recent research on the relationship of insight with behavior, mood and perceived quality of life, on its complex roots, and on the effects of existing and emerging treatments. This research indicates that poor insight predicts poorer treatment adherence and therapeutic alliance, higher symptom severity and more impaired community function, while good insight predicts a higher frequency of depression and demoralization, especially when coupled with stigma and social disadvantage...

Herbal drugs are commonly used in the treatment of several diseases, including periodontitis. So far, no systematic review had evaluated the evidence regarding the efficacy of these agents in the treatment of periodontal disease. Therefore, the purpose of this review was to evaluate the effect of local application of phytotherapic agents as adjuncts to scaling and root planing (SRP), compared to SRP alone, on clinical parameters of chronic periodontal patients. Only randomized controlled trials of at least 3 months follow-up, of SRP alone in association with local phytotherapic agents were included...

Ectomycorrhizal (ECM) fungi, as symbionts of many tree species in temperate forests, are thought to play an important role in forest regeneration processes after large disturbances. Their reaction to different disturbance and management regimes was studied in spruce forests (Lariceto-Piceetum) 10 years after a severe windthrow in the Tatra National Park (Slovak Republic). ECM community structure was compared between different "management types″-cleared area (EXT), area affected by wildfire (FIRE), uncleared area left for natural development (NEX), and mature forest as a control (REF)...

As a salt-adaptive plant, the date palm (Phoenix dactylifera L.) requires a suitable mechanism to adapt to the stress of saline soils. There is growing evidence that DNA methylation plays an important role in regulating gene expression in response to abiotic stresses, including salinity. Thus, the present study sought to examine the differential methylation status that occurs in the date palm genome when plants are exposed to salinity, and to identify salinity responsive genes that are regulated by DNA methylation...

In the root meristem, the quiescent center (QC) is surrounded by stem cells, which in turn generate the different cell types of the root. QC cells rarely divide under normal conditions but can replenish damaged stem cells. In the proximal meristem, the daughters of stem cells, which are referred to as transit amplifying cells, undergo additional rounds of cell division prior to differentiation. Here, we describe the functions of GRF-INTERACTING FACTORs (GIFs), including ANGUSTIFOLIA3 (AN3), in Arabidopsis thaliana roots...

BACKGROUND: Microvascular decompression for patients with trigeminal neuralgia (TGN) is widely accepted as one of the modalities of treatment. The standard approach has been retrosigmoid suboccipital craniotomy with placement of a Teflon pledget to cushion the trigeminal nerve from the offending artery, or cauterize and divide the offending vein(s). However, in cases of severe compression caused by a large artery, the standard decompression technique may not be effective. OBJECTIVE: To describe a unique technique of vasculopexy of the ectatic basilar artery to the tentorium in a patient with TGN attributed to a severely ectatic and tortuous basilar artery...
