Land-use intensification systematically alters the size structure of aquatic communities in the Neotropics.

Land-use and land-cover transitions can affect biodiversity and ecosystem functioning in a myriad of ways, including how energy is transferred within food-webs. Size spectra (i.e.

Links between law enforcement and veterinary animal health: a case study of the United Kingdom and the United States of America.

The anthrax attacks carried out in the United States of America in the latter part of 2001 served as a clarion call to most law enforcement agencies among developed countries as, until this time, they had not recognised the threat posed by the criminal use of pathogens and/or toxins. Law enforcement agencies include the local and federal police, Customs, Immigration and any other agencies that perform a law-enforcing role. That a criminal or terrorist group could commit such an act was considered nearly inconceivable, even though biological weapons had been used against humans and animals in warfare many times over the last several hundred years.

Absorbent alginate fibres modified with hydrolysed chitosan for wound care dressings--II. Pilot scale development.

Fibres have been used extensively in wound dressing applications as they provide a high surface area for absorption, ease of fabrication and softness. It is common practice for commercial wound dressings to be produced from natural materials, such a marine polysaccharides, as they are predominantly biocompatible, non-toxic, and often display bioactive properties, such as inherent antimicrobial activity. In this study hydrolysed chitosans were utilised as a sole coagulant for the production of alginate-chitosan fibres via a one-step, direct wet-spinning extrusion process.

A critical review of modern and emerging absorbent dressings used to treat exuding wounds.

Wound management has progressed significantly over the last five decades. This emanates from a greater understanding of wound healing, technological progression and improved clinical and scientific research. There are currently a plethora of absorbent dressings on the wound care market which claim to have the ability to manage exudates whilst encouraging healing.

Wound dressings in the 1990s.

Technology in the field of wound management is constantly progressing as researchers search for the ideal wound dressing. The regulatory situation for wound-care products can be confusing because in some cases they are considered to be pharmaceuticals and in others they are deemed to be medical devices. In addition, the situation has not been assisted by the system of risk classification in the Medical Device Directive.
