The article presents cluttering as understood as a specific communication disorder. Cluttering has received less coverage in the subject literature than stuttering and is comparatively poorly understood. Defining cluttering presents us with a problem due to differences of opinion as to which of the behaviours associated with the disorder are crucial to its diagnosis and which are rather periphe...

The present study aims to explore the possible mechanisms underlying the multidrug resistance characteristic of Cryptosporidium parvum by detecting the presence of ATP-binding cassette (ABC) protein encoding genes, especially one that shows high similarity to members belonging to the multidrug resistance protein (MDR) and multidrug resistance associated protein (MRP) subfamilies. PCR using ABC-...

Caches play an important role in embedded systems to bridge the performance gap between fast processor and slow memory. And prefetching mechanisms are proposed to further improve the cache performance. While in real-time systems, the application of caches complicates the Worst-Case Execution Time (WCET) analysis due to its unpredictable behavior. Modern embedded processors often equip locking m...

The susceptibility of 14 species of 115 Gram-positive anaerobic cocci (GPAC) was determined for 14 antibiotics. To assure correct identification, strains were genotypically identified by fluorescence in situ hybridization and sequencing. Susceptibility differences (MIC₅₀ and MIC₉₀) for penicillin G, clindamycin, tigecycline, levofloxacin, amoxicillin-clavulanic acid, cefoxitin, ertapenem, merop...

Single s.c. injections of 500 ^g 7,12-dimethylbenz(a)anthracene in tricaprylin were given to 25 males and 25 females of 10 inbred strains of Syrian hamsters. In 9 strains, the average time of latency before palpable tu mors appeared was 13 to 16 weeks. In 1 strain, BIO 15.16, the average latency was 10 weeks. These differ ences are statistically significant. In this line, the first palpable tum...

The efficacy of eight routine enteric agars for supporting the growth of 32 strains of Aeromonas spp. (17 A. hydrophila strains, 8 A. sobria strains, and 7 A. caviae strains) was investigated. The plating efficiency of Aeromonas spp. on these media varied greatly (range, 0 to 100%), as did their colony size when compared with that on noninhibitory medium (5% sheep blood agar). Plating efficienc...

Cryptococcus neoformans has two varieties, var. grubii and var. neoformans, that correspond to serotypes A and D, respectively. Molecular phylogenetic analyses suggest that these two varieties have diverged from each other for approximately 18 million years. The discovery of pathogenic serotype AD hybrid strains in nature indicates that intervariety mating in C. neoformans occurs in the natural...
