objective: this study was carried out to investigate the preventive effects of hydroalcoholic extract of cynodon dactylon(c.dactylon) roots on calcium oxalate calculi in rat. materials and methods: 24 wistar rats were randomly divided into 4 groups: group a received tap drinking water while, groups b, c, and d received 1% ethylene glycol daily for 28 days. rats in groups c and d received ethano...

Cycloheximide inhibited ethylene production in excised pea root tips treated with high levels of indoleacetic acid (100 mum and 10 mum). In contrast, cycloheximide did not inhibit ethylene production induced by a lower concentration (1 mum) of indoleacetic acid unless it was added 2 hours before the indoleacetic acid treatment. These observations suggest that indoleacetic acid has two effects o...

Excised albedo tissue of citrus fruit (Citrus unshiu and Citrus hassaku) produced ethylene at an increasing rate in response to wounding and aging. The application of 1-aminocyclopropane-1-carboxylic acid (ACC) enhanced ethylene production in both the fresh and aged tissues, but this increase was greater in the aged tissue than in the fresh tissue. ACC content was very low in fresh tissue but i...

The presence of either copper(I) or copper(II) chloride in the polyol reduction of silver nitrate facilitates the production of silver nanowires. Silver nanowires have applications in many areas, including electronics and catalysis. These wires are produced quickly (in approximately one hour), with the synthesis being easily performed in disposable glass vials, using only pipettes to deliver re...

Background Waste biomass from agro-food industries are a reliable and readily exploitable resource. From the circular economy point of view, direct residues from these industries exploited for production of fuel/chemicals is a winning issue, because it reduces the environmental/cost impact and improves the eco-sustainability of productions. Results The present paper reports recent results of ...

The rates of a-aminoisobutyrate (AIB) transport and cyclic adenosine 3':5'-monophosphate (cAMP) production in re sponse to glucagon (2 x 10~7 M) have been determined in monolayer cultures of hepatoma cell line 8994 (refers to hepatoma cell line McA-RH 8994) under three different calcium treatments. The calcium treatments were: (a) control, cultures maintained in calcium-containing medium withou...

Background: The animal is tremendously challenged to maintain calcium homeostasis. Those that fail can develop milk fever, a clinical disorder that is life threatening to the cow and predisposes the animal to a variety of other disorders. Calcium defi ciency disease is often accompanied with a defi ciency in phosphorus in clinical cases. Blood phosphorus status has also been researched because ...

Inhibition of root elongation is one of the most distinct symptoms of aluminium (Al) toxicity. Although putrescine (Put) has been identified as an important signaling molecule involved in Al tolerance, it is yet unknown how Put mitigates Al-induced root inhibition. Here, the possible mechanism was investigated by using two wheat genotypes differing in Al resistance: Al-tolerant Xi Aimai-1 and A...
