background there is currently great concern about the possible adverse effect of microwave radiation from cell phones. in addition, noise is one of the physical pollutants of modern societies. objectives the present study aimed to examine the separate and simultaneous effects of cell phone microwaves, noise, and their effects on sperm parameters and total antioxidant capacity in adult male rats...

by Charles L. Penninger One of the most intriguing aspects of bone is its ability to grow, repair damage, adapt to mechanical loads, and maintain mineral homeostasis. It is generally accepted that bone adaptation occurs in response to the mechanical demands of our daily activities; moreover, strain and microdamage have been implicated as potential stimuli that regulate this sophisticated proces...

purpose: evaluation of humoral and cellular immune responses of naturally infected dogs against type i (rcpb) (recombinant cycsteine proteinase b), and ii (rcpa) (recombinant cycsteine proteinase a) recombinant cysteine proteinases and c-terminal extension (cte) of leishmania infantum (l. infantum). materials and methods: in this study, fourteen infected dogs (7 with symptoms, 7 asymptomatics)...

A new method and a new type of measuring-microchamber for the investigation of cellular dielectrophoresis is presented. The method is based on the observation of the trajectory of a single cell in gravitational and electric fields being crossed and orientated perpendicularly to the observation direction. By means of this method the whole dielectrophoretic spectrum ranging from negative to posit...

In order for nanoparticles (NPs) to be applied in the biomedical field, a thorough investigation of their interactions with biological systems is required. Although this is a growing area of research, there is a paucity of comprehensive data in cell-based studies. To address this, we analyzed the physicomechanical responses of human alveolar epithelial cells (A549), mouse fibroblasts (NIH3T3), ...

Quantum-dot cellular automaton at this moment works properly at very low temperature region. How to avoid or increase the low temperature limit is investigated.

A regional genetic register for Huntington's chorea in South Wales is described, based on previous family studies in this area, which is one of high prevalence for the disorder. The primary role of the register is to help in the efficient delivery of services, including genetic counselling, to affected subjects and relatives, and to monitor changes in the population at risk. The mode of operati...
