Al toxicity in plants is related to the activity of Ae+ and AI­ hydroxy monomers in the soil solution, whereas Al complexed with ligands such as fluoride (F), s~lphate (SQ42-), and oxalate is not toxic. Estimation of toxic Al relies on measurement of "labile" Al after short contact times with colorimetric reagents or cation-exchange resins. However, shifts in equilibrium may result in non-toxic...

migraine is a common and incapacitating neurologic disorder manifesting with episodic moderate to a severe headache and other symptoms such as photophobia, phonophobia, nausea, and vomiting. triptans and ergot compounds have been used as treatment options for an acute migraine headache for many years. triptans are considered the first line of treatment in patients with moderate to a severe migr...

The experiment was carried out to assess dry matter accumulation and potassium partitioning in submerged rice upon application of three organic salts, viz., citrate (KC), gluconate (KG), humate (KH), inorganic salt, sulfate (KS). Treatments included recommended dose (RDF-K, 60 kg ha−1) via foliar or soil KS, alone combination with salts (KC, KG, KH), split doses at phenological stages, tillerin...
