Galectins are a galactoside specific subclass of carbohydrate binding proteins (lectins) involved in various cellular activities, certain cancers, infections, inflammations, and many other biological processes. The molecular basis for the selectivity galectins is well-documented revolves around appropriate interaction complementarity: an aromatic residue C−H⋅⋅⋅π interactions polar residues (cha...

conclusions in patients with abdominal or pelvic masses and a history of previous abdominal surgery, the possibility of gossypiboma should be kept in mind. case presentation we report two patients (the first patient was 50 years old, with a history of an appendectomy three years ago in another city; the second patient was 52 years old, with a history of a cesarean section 25 years ago in anothe...

ing at the University of Arizona. Saadatmanesh developed the material, called CarbonWrap, about six years ago and now sells it through CarbonWrap Solutions. The polymer is made of woven filaments of glass, carbon and Kevlar, which are placed in a resin matrix. Its tensile strength—the force required to pull it apart—is about 200 tons per square inch, 10 times stronger than steel. The fiber cost...

Azobenzene-3,3'-dicarboxylic acid exists in photoisomerizable (E) and (Z)-forms. Deprotonation of the carboxylic acid groups from the (E)-form occurs simultaneously, whereas in the (Z)-form it occurs in a stepwise fashion. The mono anionic form of the (Z)-isomer acts as a glycosidase mimic that proceeds through a general acid-general base catalytic mechanism. This is the first example of a phot...

Leptospirosis is a potentially fatal bacterial disease that can display a wide array of clinical presentations thus mimicking better-known illnesses. Although, leptospirosis is primarily a zoonotic disease, it frequently inflicts severe illness and death on communities around the globe. A comprehensive overview of the disease in wake of the 2006 outbreaks in India is hereby presented and discus...

In this paper, chaos is applied to the control of moving robots in order to generate random-like trajectories needed in tasks such as exploration, scanning natural terrains or mapping of unknown environments. Synchronization between the robots of a team is achieved by exploiting the paradigm of mirror neurons, i.e. a neural structure playing a key role in the process of imitation and behaviour ...

BACKGROUND Collagen is the most abundant protein in animals. Each polypeptide chain of collagen is composed of repeats of the sequence: Gly-X-Y, where X and Y are often L-proline (Pro) and 4(R)-hydroxy-L-proline (Hyp) residues, respectively. These chains are wound into tight triple helices of great stability. The hydroxyl group of Hyp residues contributes much to this conformational stability. ...
