Isolation and Antitumoral Effect of a New Siphonochilone Derivative from African Ginger.

A new eusdesmane sesquiterpenoid, characterized as 3,5,8a-trimethyl-8-oxo-4,4a,5,6,7,8,8a,9-octahydronaphtho[2,3-]furan-5-yl acetate (), has been isolated from the rhizomes of the South African variety of wild ginger ( (Schweinf) B. L. Burtt).

Insulin purification-Innovation continuum via synthesis of fundamentals, technology, and modeling.

Advancement in all disciplines (art, science, education, and engineering) requires a careful balance of disruption and advancement of classical techniques. Often technologies are created with a limited understanding of fundamental principles and are prematurely abandoned. Over time, knowledge improves, new opportunities are identified, and technology is reassessed in a different light leading to a renaissance.

Serious Games for Training Myoelectric Prostheses through Multi-Contact Devices.

In the medical context, designing and developing myoelectric prostheses has made it possible for patients to regain mobility lost due to amputations; however, their use requires intensive training. Serious games through multi-touch devices can serve as a complement to the activities carried out during face-to-face sessions with occupational therapists and physiotherapists, as a useful resource to engage patients, especially children, and make them enjoy training. In this paper, we describe our work to support the training of myoelectric prostheses through digital serious games.

Identification of Compounds with Potential Therapeutic Uses from Sweet Pepper ( L.) Fruits and Their Modulation by Nitric Oxide (NO).

Plant species are precursors of a wide variety of secondary metabolites that, besides being useful for themselves, can also be used by humans for their consumption and economic benefit. Pepper ( L.) fruit is not only a common food and spice source, it also stands out for containing high amounts of antioxidants (such as vitamins C and A), polyphenols and capsaicinoids.

The JA-pathway MYC transcription factors regulate photomorphogenic responses by targeting HY5 gene expression.

Jasmonates are key regulators of the balance between defence and growth in plants. However, the molecular mechanisms by which activation of defence reduces growth are not yet fully understood. Here, we analyze the role of MYC transcription factors (TFs) and jasmonic acid (JA) in photomorphogenic growth.
