Neutrophils, crucial players in the effector phase of the immune response, are recognized as important mediators of both innate and adaptive immune responses. Through the production of pro- and anti-inflammatory cytokines, they modulate the function of T and other lymphoid cells. Countless reports have highlighted the importance of these cells as efficient antimicrobial agents and annotated their involvement in the pathology of infectious and noninfectious diseases. The development of modern, sophisticated technologies has allowed the study of the functions of these cells in clinical settings. These advanced technologies include fluorescence-activated cell sorters, confocal microscopy, automated cell image analyzers, and live cell analysis instruments. Unfortunately, the cost of these modern instruments, maintenance, reagents, and the need for qualified technicians prohibit their use in low-income laboratories and universities in developing countries. With this in mind, we propose a series of basic tests that can be used in low-input clinical laboratories and universities to evaluate the function of neutrophils in health and disease. Our methodology allows us to assess in a practical and low-cost manner the functions of neutrophils in the phagocytic process, including opsonization, ingestion, ROI production (NBT reduction), myeloperoxidase content, phagosome-lysosome fusion, microbicidal activity, and NET production. Thus, under a disadvantageous ambiance, this may guide physicians in deciding whether a patient’s illness involves phagocytic defects without imposing a heavy financial *** Abstract[-rId13-]

The widespread availability of portable computing power and inexpensive digital cameras are opening up new possibilities for retailers in some markets. One example is in optical shops,where a number of systems exist that facilitate eyeglassess election. These systems are now more necessary as the market is saturated with an increasingly complex array of lenses,frames,coatings,tints,photochromic and polarizing treatments,etc. Research challenges encompass Computer Vision,Multimedia andHuman-Computer Interaction. Cost factors are also of importance for widespread product acceptance. This paper describes alow-cost system that allows the user to visualize different glasses models in live video. The user can also move the glasses toadjust its position on the face. The system,which runs at 9.5 frames/s on general-purpose hardware,has a homeostatic modulethat keeps image parameters controlled. This is achieved by using a camera with motorized zoom,iris,white balance,etc. Thisfeature can be specially useful in environments with changing illumination and shadows,like in an optical shop. The system alsoincludes a face and eye detection module and a glasses management module.

Changes in social and emotional behaviour have been consistently observed in patients with traumatic brain injury. These changes are associated with emotion recognition deficits which represent one of the major barriers to a successful familiar and social reintegration. In the present study, 32 patients with traumatic brain injury, involving the frontal lobe, and 41 age- and education-matched healthy controls were analyzed. A Go/No-Go task was designed, where each participant had to recognize faces representing three social emotions （arrogance, guilt and jealousy）. Results suggested that ability to recognize two social emotions （arrogance and jealousy） was significantly reduced in patients with traumatic brain injury, indicating frontal lesion can reduce emotion recognition ability. In addition, the analysis of the results for hemispheric lesion location （right, left or bilateral） suggested the bilateral lesion sub-group showed a lower accuracy on all social emotions.
