AIM To develop a simplified bioartificial liver (BAL) device prototype, suitable to use freshly and preserved liver Microorgans (LMOs) as biological component. METHODS The system consists of 140 capillary fibers through which goat blood is pumped. The evolution of hematocrit, plasma and extra-fiber fluid osmolality was evaluated without any biological component, to characterize the prototype....

apparent rise in the incidence of infertility in females and the trend shifting towards delayed child bearing brought up the concept of ovarian ageing. women in their early thirties show poor ovarian reserve which is an entity named as early ovarian ageing. early ovarian ageing is mostly genetically determined, but acquired modifiable factors like smoking, or ovarian surgery have some roles. in...

This article presents the significance of biodiversity, biotechnology and health and discusses many aspects of biological and environmental problems as well as the ethical dilemma related to expansion and exploitation of natural resources, which promoted a decline in biological diversity. In addition, knowledge of biodiversity has allowed for identification and use of new natural resources, use...

The decision whether to retain a tooth by additional endodontic and restorative treatments or to extract it and replace it with an implant-supported restoration has been extensively debated, and the common approach to this clinical question has shifted back and forth many times. However, in recent years, it has become clear that implants are more prone to technical and biological complications,...

The stages of economic growth in most countries have been historically dependent on the non-judicious use of natural resources that have a direct productive role, and are clearly identifiable as a market good, by its price [1]. Under the concept of equitable use of natural resources, the universally accepted premise is that unplanned and uncontrolled growth of business contributes to irreversib...

Preservation of natural sausage casings using dry salt or saturated brine is regarded as sufficient to inactivate vegetative pathogenic non-spore-forming bacteria present on the casings. Although the outgrowth of bacterial spores is prevented by salt or saturated brine preservation, these spores will remain present and develop into vegetative cells when conditions are more favourable. To preven...
