Hydrogen gas (H2) is involved in plant development and stress responses. Cucumber explants were used to study whether nitric oxide (NO) is involved in H2-induced adventitious root development. The results revealed that 50% and 100% hydrogen-rich water (HRW) apparently promoted the development of adventitious root in cucumber. While, the responses of HRW-induced adventitious rooting were blocked by a specific NO scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide potassium salt (cPTIO), NO synthase (NOS) enzyme inhibitor NG-nitro-l-arginine methylester hydrochloride (l-NAME) and nitrate reductase (NR) inhibitor NaN3. HRW also increased NO content and NOS and NR activity both in a dose- and time-dependent fashion. Moreover, molecular evidence showed that HRW up-regulated NR genes expression in explants. The results indicate the importance of NOS and NR enzymes, which might be responsible for NO production in explants during H2-induced root organogenesis.

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract.

OBJECTIVE: Hypercapnia resulting from protective ventilation in acute respiratory distress syndrome triggers metabolic pH compensation, which is not entirely characterized. We aimed to describe this metabolic compensation.

The aim was to evaluate the addition of microencapsulated jabuticaba extract (MJE) to fresh sausage as natural dye with antioxidant and antimicrobial activity. Fresh sausages without dye, with cochineal carmine and with addition of 2% and 4% MJE were evaluated for chemical, microbiological and sensory properties during 15days of refrigerated storage. TBARS values were lower (P<0.05) throughout the storage period in sausages with 2% and 4% MJE (below 0.1mg of malondialdehyde/kg sample) than in control and carmine treatments (from 0.3 to 0.6mg of malondialdehyde/kg sample). T2% and T4% also showed lower microbial counts on storage days 4 and 15 for APCs. The addition of 4% MJE negatively influenced (P<0.05) sensory color, texture and overall acceptance attributes. On the other hand, T2% presented similar (P>0.05) sensory acceptance to control and carmine treatments in most of the attributes evaluated except for a decrease in color.
