Exogenous salicylic acid reduces cadmium content in spinach (Spinacia oleracea L.) shoots under cadmium stress.

Background: Consumption of leafy vegetables is a primary route of cadmium (Cd) exposure in the human body. Salicylic acid (SA) is a major stress signaling molecule that alleviates Cd toxicity in various plants. Our study aimed to investigate the effects of different SA concentrations on spinach growth, cadmium accumulation, and stress resistance physiology under cadmium stress (50 µmol/L).

Biological features and quality comprehensive analysis of twelve germplasm resources of the genus from Tibet.

Introduction: is important vegetables and seasonings in China, Tibet is rich in unique resources of the genus , but lacks development and utilization.

Methods: We compared the biological features and comprehensively evaluating the quality of twelve germplasm resources of the genus collected from Tibet.

Results: The results revealed that nine germplasm resources were bolting and bloom normally except for SC015, SC019, and SC048, all twelve germplasm resources were able to vegetative growth.

Chemical fertilizer reduction combined with bio-organic fertilizers increases cauliflower yield regulation of soil biochemical properties and bacterial communities in Northwest China.

The continuous application of chemical fertilizers in vegetable cropping has led to deterioration of the soil environment and reduced yield and quality. The objective of this study was to evaluate the effect of combining chemical and bio-organic fertilizers on cauliflower yield, soil biochemical properties, and the bacterial community. Six treatments were established: no fertilizer (CK, control), chemical fertilizers (CF, conventional dosage for this region), balanced fertilization (BF, 30% reduction of chemical fertilizers), and balanced fertilization plus 3,000, 6,000, or 12,000 kg.

[Combinational expression of geranylgeranyl diphosphate synthase and taxadiene synthase in Coprinopsis cinerea].

Taxa-4(5),11(12)-diene is the precursor for paclitaxel biosynthesis. The diterpenoid paclitaxel (marketed as Taxol), a plant secondary metabolite isolated from yew, is an effective drug widely used in the treatment of numerous cancers. However, further application of taxol has been restricted due to its low yield in plants and the difficulties in extraction.

A novel systems pharmacology model for herbal medicine injection: a case using Reduning injection.

Background: Compared with the traditional oral administration form, injection administration is basically superior in terms of both biological availability and therapeutic effects. However, few researches have focused on the traditional Chinese medicinal injection due to the complicated constituents and the intricate mechanism of action.

Methods: In the present work, a novel systems pharmacology model, integrating ADME (absorption, distribution, metabolism, and excretion) filtering such as half-life evaluation, network targeting, pathway and systems analyses, is specifically developed for the identification of active compounds and the study of the mechanism of action of TCM injection, which is exemplified by Reduning injection confronting the influenza.

[Effects of different nitrogen forms and their ratios on broccoli yield, quality, and nutrient absorption].

A field experiment was conducted to study the effects of different nitrogen forms ((NH2)2CO-N, NO(3-)-N, NH(4+)-N, and NO(3-)-NH4+) and their ratios on the yield formation, quality, and nutrient (N, P, and K) absorption of broccoli (Brassica oleracea). Fertilization with NO(3-)-N increased the accumulation of nitrate and soluble sugars in ball flower. When the NO(3-)-N: NH(4+)-N ratio was ranged from 3:7 to 5:5 and from 5:5 to 7:3, respectively, the accumulation of nitrate in the ball flower was reduced, while the soluble sugars content was promoted.

Acute effects of high-protein versus normal-protein isocaloric meals on satiety and ghrelin.

Purpose: The objective was to compare isocaloric high-protein (HP) test meals with normal-protein (NP) test ones on satiety and ghrelin in human being.

Methods: Systematic searches were conducted by using PubMed, Cochrane library, EMBASE, and HighWire Press to identify randomized, crossover trials that investigated the acute effects of isocalorically prescribed HP versus NP test meals on satiety and ghrelin.

Results: Pooled analyses showed that subjects with HP test meals had a significantly higher acute satiety area under the curve (AUC) than those with NP test meals (P < 0.

Molecular cloning of a laccase gene from Ganoderma lucidum and heterologous expression in Pichia pastoris.

A genomic laccase gene and cDNA were cloned from the white-rot fungi Ganoderma lucidum TR6. The genomic laccase gene contained 2086 bp with nine introns. The laccase cDNA had an open reading frame of 1563 bp.

The impact of effective continuous positive airway pressure on homeostasis model assessment insulin resistance in non-diabetic patients with moderate to severe obstructive sleep apnea.

Previous studies on the effects of continuous positive airway pressure (CPAP) on homeostasis model assessment insulin resistance (HOMA-IR) in obstructive sleep apnea patients have yielded conflicting results. Therefore, we conducted this meta-analysis to evaluate the impact of effective CPAP on HOMA-IR in non-diabetic patients with moderate to severe obstructive sleep apnea. We searched PubMed, HighWire Press, Ovid Medline (R), Cochrane library and EMBASE before December 2011 on original English language studies.

Effects of continuous positive airway pressure on glycemic control and insulin resistance in patients with obstructive sleep apnea: a meta-analysis.

Background: Previous studies addressing the question of whether continuous positive airway pressure (CPAP) could improve the insulin resistance and glucose control in patients with obstructive sleep apnea (OSA) have led to conflicting results. Therefore, we conducted the meta-analysis to evaluate the effects of CPAP on glycemic control and insulin resistance in OSA patients.

Methods: We searched PubMed, HighWire Press, Ovid Medline (R), Cochrane library, and EMBASE before December 2011 on original English language studies.
