Members of the Mycobacterium avium complex (MAC) may cause chronic pulmonary infections in otherwise healthy elderly persons but rarely invade parts of the body outside of the lungs in immunocompetent hosts. We present a case of an isolated intracranial MAC infection in an apparently immunocompetent individual and review previous reports. We studied the T-cell and monocyte responses in healthy ...

OBJECTIVE The aim of the present study was to study time indices of heart rate variability (HRV) in patients with mitral annular calcification (MAC). METHODS A cross-sectional observational study was performed. Fifty patients with echocardiographic evidence of MAC and 50 age- and gender-matched control subjects without echocardiographic evidence of MAC were included. All the study participant...

The notion of machine-aided cognition implies an intimate collaboration between a human user and a computer in a real-time dialogue on the solution of a problem, in which the two parties contribute their best capabilities. In order for this intimate collaboration to be possible, a computer system is needed that can serve simultaneously a large number of people, and that is easily accessible to ...

This paper proposes a novel media access control (MAC) mechanism, called the robust preamble-based MAC mechanism (R-PMAC), which can be applied to power line communication (PLC) networks in context of Industrial Internet Things (IIoT). Compared with other mechanisms such as P-MAC and layer IEEE1901.1, R-PMAC has higher networking speed. Besides, it supports whitelist authentication functions pr...

The use of monitored anaesthesia care (MAC) is increasing with the discovery of newer, more effective and appropriate drugs and techniques. MAC is intended to achieve patient comfort with safety and optimal clinical outcome and is being extensively used worldwide for cataract and other ophthalmic surgeries. This article briefly reviews the conceptual basis of MAC, its use in ophthalmic surgerie...

Free-standing monolayer amorphous carbon (MAC) is a pure structure composed of randomly distributed atom rings with different sizes, which was recently synthesized. In this work, we carried out ab initio and tight-binding calculations to investigate the optoelectronic properties MAC its derived nanotube nanoscroll configurations. Our results show MAC, tube, scrolls exhibit similar electronic be...

INTRODUCTION The aim of this study was to investigate the diagnostic performance of measuring antibodies to the glycopeptidolipid (GPL) core antigen specific to Mycobacterium avium complex (MAC) in patients with rheumatoid arthritis (RA). METHODS We cross-sectionally investigated anti-GPL antibodies and radiographs of 396 patients with RA. A diagnosis of MAC pulmonary disease (MAC-PD) was mad...

We have examined the effects of inhalation anaesthetics on indocyanine green (ICG) clearance, as an index of hepatic function, in patients undergoing elective surgery. Recently, a new method has been developed to measure in real-time the disappearance rate of ICG from plasma. This method eliminates the multiple sampling and delay of the conventional ICG test. ICG clearance is displayed as two i...
