OBJECTIVES The aim of this study was to emphasize the necessity of a standard in segmentation threshold and algorithm for measuring volume and surface area of mastoid air cell system (MACS). METHODS First, we obtained axial computed tomography scans of 54 normal temporal bones from 27 subjects. Then, we manipulated Hounsfield units (HU) image data in DICOM (digital imaging and communications ...

BACKGROUND The Manual Ability Classification System (MACS) has been widely used to describe the manual ability of children with cerebral palsy (CP); however its reliability has not been verified in Brazil. OBJECTIVE To establish the inter- and intra-rater reliability of the Portuguese-Brazil version of the MACS by comparing the classifications given by therapists and parents of children with ...

Human jaw periosteum tissue contains osteoprogenitors that have potential for tissue engineering applications in oral and maxillofacial surgeries. To isolate osteoprogenitor cells from heterogeneous cell populations, we used the specific mesenchymal stem cell antigen-1 (MSCA-1) antibody and compared two magnetic separation methods. We analyzed the obtained MSCA-1(+) and MSCA-1(-) fractions in t...

OBJECTIVE It is believed that monocyte isolation methods and maturation factors affect the phenotypic and functional characteristics of resultant dendritic cells (DC). In the present study, we compared two monocyte isolation methods, including plastic adherence-dendritic cells (Adh-DC) and magnetic activated cell sorting- dendritic cells (MACS-DC), and their effects on phagocytic activity of di...

Computationally intensive inference tasks of deep neural networks have brought about a revolution in accelerator architecture, aiming to reduce power consumption as well latency. The key figure-of-merit hardware accelerators is the number multiply-and-accumulation operations per watt (MACs/W); state-of- the-art MACs/W, so far, has been several hundreds Giga-MACs/W. We propose Tera- MACS/W (TMA)...

John Fahey was one of the first investigators to study the then-new acquired immune deficiency syndrome (AIDS). He made major contributions to the design of the Multicenter AIDS Cohort Study (MACS), and vigorously promoted novel and high-quality science as the MACS evolved. His contributions are highly valued.

Assisted reproductive techniques (ARTs) have become the treatment of choice in many cases of infertility; however, the current success rates of these procedures remain suboptimal. Programmed cell death (apoptosis) most likely contributes to failed ART and to the decrease in sperm quality after cryopreservation. There is a likelihood that some sperm selected for ART will display features of apop...
