Antimicrobial activity of camphor tree silver nano-particles against foulbrood diseases and finding out new strain of as a secondary infection on honeybee larvae.

American foulbrood (AFB) and European foulbrood (EFB) are the two major bacterial diseases affecting honeybees, leading to a decrease in viability of the hive, decreasing honey production, and resulting in significant economic losses to beekeepers. Due to the inefficiency and/or low efficacy of some antibiotics, researches with nanotechnology represent, possibly, new therapeutic strategies. Nanostructure drugs have presented some advantagesover the conventional medicines, such as slow, gradual and controlled release, increased bioavailability, and reduced side-effects.

Comparison of uridine diphosphate-glycosyltransferase UGT76G1 genes from some varieties of Stevia rebaudiana Bertoni.

Stevia leaves contain various components, such as flavonoids, labdanes, chlorophylls, sterols, triterpenoids, mono-disaccharides, organic acids and inorganic salts. Stevia is known to accumulate diterpenoid steviol glycosides, which are approximately 300 times sweeter than regular sugar. Stevioside and rebaudioside A are the main diterpenic glycosides in stevia.

The treatment of sleep disorders.

Narcolepsy is clinically associated with cataplexy, sleep paralysis and hypnagogic hallucinations. It is treated by reassurance (that there is no physical disease) and by stimulants such as ephedrine and amphetamine on an intermittent basis. The special tricyclic antidepressant clomipramine is also used, and mono-amine oxidase inhibitors (MAOIs) are useful in theory.

Clinical assessment and performance tasks in depression: a comparison of amitriptyline and trazodone.

Depression, anxiety and psychomotor performance were assessed in 20 depressed patients during double-blind treatment with amitriptyline or trazodone. There was no difference in onset of antidepressant or anxiolytic action. No decrement or improvement on computerised tasks was found.
