[Physiological and biochemical mechanism of spermidine improving drought resistance in maize seedlings under drought stress.].

To explore the role of exogenous spermidine (Spd) in enhancing the resistance of maize to drought stress, 15% polyethylene glycol (PEG-6000) was used to simulate drought stress and with 'Xianyu 335' (drought-insensitive) and 'Fenghe 1' (drought sensitive) as the experiment materials, the effects of Spd (0.1 mmol·L) on the growth, photosynthetic characteristics, chlorophyll content, osmotic adjustment substance, membrane lipid peroxidation and root activity of maize seedlings were investigated. The results showed that the application of Spd significantly promoted the growth of maize seedlings under drought stress, increased chlorophyll content, net photosynthetic rate (P), stomatal conductance (g), transpiration rate (T) and water use efficiency (WUE), and decreased the enhancement of intercellular carbon dioxide concentration (C) in 'Fenghe 1'.

Development and characterization of an α-l-rhamnosidase mutant with improved thermostability and a higher efficiency for debittering orange juice.

The glycoside hydrolase, α-l-rhamnosidase, could remove the bitter taste of naringin from citrus juices. However, most α-l-rhamnosidases are easily deactivated at high temperatures, limiting the practice in debittering citrus juices. The V529A mutant of the α-l-rhamnosidase r-Rha1 from Aspergillus niger JMU-TS528 was developed with improved thermostability using directed evolution technology and site-directed mutagenesis.

Water accelerated transformation of d-limonene induced by ultraviolet irradiation and air exposure.

d-Limonene is a fragrant chemical that widely exists in aromatic products. Isotopic labelling of water molecules plus GC-MS and GC-PCI-Q-TOF analyses were used to investigate the influence of water molecules on chemical transformation of d-limonene induced by UV irradiation and air exposure. The results showed that the synergistic effect of UV irradiation, air exposure and water presence could facilitate d-limonene transformation into the limonene oxides: p-mentha-2,8-dienols, hydroperoxides, carveols, l-carvone and carvone oxide.

Recovery and purification of limonin from pummelo [Citrus grandis] peel using water extraction, ammonium sulfate precipitation and resin adsorption.

Limonin is a bioactive compound that is traditionally extracted from citrus seeds using organic solvents or alkaline/metal ion solutions. In the present study, pummelo [Citrus grandis] peel was investigated for limonin preparation using a novel process consisting of water extraction, ammonium sulfate precipitation and resin adsorption. The pummelo peel was determined to have 4.

Recent Advances in Antischistosomal Drugs and Agents.

Schistosomiasis is a notable neglected tropical disease caused by trematodes that inflame mainly the intestines, bladder, and liver. Because of the unavailability of a schistosomiasis vaccine, control of the disease depends mainly on chemotherapy. Praziquantel (PZQ), which is active against all schistosome species and the recommended drug by the World Health Organization for schistosomiasis treatment at either the community or individual level, has become the exclusive drug because of its low cost and efficacy against the adult form of all schistosome species.

Increased CD34+CD38 -CD123 + cells in myelodysplastic syndrome displaying malignant features similar to those in AML.

Leukocyte interleukin-3 receptor α (CD123) is regarded as a marker of leukemia stem cells. We previously found that CD123 was also highly expressed on CD34(+)CD38(-) cells in myelodysplastic syndrome (MDS) patients, but it is unclear whether the level and the characteristics of CD34(+)CD38(-)CD123(+) cells in MDS are similar to those in acute myeloid leukemia (AML). Based on previous research by our team, we further enlarged the specimens and found that the mean proportion and the mean MFI of CD34(+)CD38(-)CD123(+) cells in low-grade MDS were lower than that in AML, and those in high-grade MDS were similar to those in AML.
