This study sought to describe speech-language interventions for preschool-aged children who required augmentative and alternative communication (AAC) as provided by AAC experts and by general speech-language pathologists who were not AAC experts. The study also examined the types of technology used in AAC intervention by AAC experts. A retrospective chart review was conducted in which clinic re...

Recently, the MPEG committee has completed the development of a new audio coding standard, the MPEG-4 Advanced Audio Coding-Enhanced Low Delay (AAC-ELD). The stateof-the-art MPEG audio coding standards, such as MPEG-4 AAC Low Complexity (AAC-LC), High Efficiency AAC (HE-AAC) and AAC Low Delay (AAC-LD), utilize for the time-tofrequency transformation of an audio block and vice versa, the well kn...

The aac(6')-Ib gene is the most prevalent gene that encodes aminoglycoside-modifying enzymes and confers resistance to tobramycin, kanamycin, and amikacin. The aac(6')-Ib-cr variant gene can induce resistance against aminoglycoside and fluoroquinolone simultaneously. Two main methods, sequence analysis and the restriction enzyme method, can detect the aac(6')-Ib-cr variant in clinical strains. ...

OBJECTIVE Acute acalculous cholecystitis (AAC) is traditionally known to occur in critically ill patients and to have a poor prognosis. Although cholecystectomy is usually recommended for treating AAC, nonsurgical management may be a good alternative. The objective of this study was to review the incidence, risk factors, treatment modality, and therapeutic outcomes of AAC compared to acute calc...

Inflammation of the gallbladder without evidence of calculi is known as acute acalculous cholecystitis (AAC). AAC is frequently associated with a poor prognosis and a high mortality rate. Thus, early diagnosis and prompt surgical intervention has been recommended to improve the outcome of AAC. Herein, I present a case report of AAC complicating laparoscopic appendicectomy. Unlike previous studi...

OBJECTIVE To evaluate the predictive value of abdominal aortic calcium (AAC) for incident cardiovascular disease (CVD) independent of coronary artery calcium (CAC). APPROACH AND RESULTS We evaluated the association of AAC with CVD in 1974 men and women aged 45 to 84 years randomly selected from the Multi-Ethnic Study of Atherosclerosis participants who had complete AAC and CAC data from compu...

The AAC(3)-V resistance mechanism is characterized by high-level resistance to the aminoglycosides gentamicin, netilmicin, 2'-N-ethylnetilmicin, and 6'-N-ethylnetilmicin and moderate resistance levels to tobramycin. Serratia marcescens 82041944 contains an AA(3)-V resistance mechanism as determined from aminoglycoside resistance profiles. This strain, however, does not exhibit hybridization wit...

Renal denervation (RD) was reported to reduce the susceptibility of atrial fibrillation (AF), but the underlying mechanism has not been well understood. This study was performed to investigate the effect of RD on the inducibility of AF in a rabbit model for atrial fibrosis and to explore the potential mechanisms. Thirty-five rabbits were randomly assigned into sham-operated group (n = 12), abdo...
