The most accepted method of secondary prophylaxis in rheumatic fever (RF) has been an injection of 1,200,000 units of benzathine penicillin G (BPG) every 4 weeks, but recurrences have been reported in some patients despite such a prophylaxis program. The WHO recommended BPG injections every 3 weeks in high risk patients and situations due to some published data in favor of inadequacy of on...

A Software Product Line (SPL) is a set of related programs. A SPL of a SPL (SPL), or a product line of a product line, is a fundamental scaling of product line concepts. A member of a SPL is not a program, but a SPL. The idea recurses: a SPL is a SPL of a SPL, and so on. The depth of recursion is the rank of the product line. We present an algebra to understand and build feature-based product l...

Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid that activates a family of G protein coupled-receptors (GPCRs) implicated in mammalian development, angiogenesis, immunity and tissue regeneration. S1P functions as a trophic factor for many cell types, including embryonic stem cells (ESCs). Sphingosine phosphate lyase (SPL) is an intracellular enzyme that catalyzes the irreversible degr...

Objetivo: Avaliar o a influência da remoção de resíduos dois cimentos à base resina epóxi (SPL, Sealer Plus ou S26, 26), com etanol 95% (ETA) xilol (XIL), na interface adesão entre sistema adesivo universal (SBU, Scotchbond Universal), utilizado estratégia condiciona-e-lava, e substrato dentinário coroa dental, por meio avaliação resistência união (RU), avaliada pelo teste microcisalhamento, an...

we compared the extent of temporary threshold shift (tts) and hair cell loss following high level 4 khz noise exposure with those preconditioned with moderate level 1 and 4 khz octave band noise. fifteen male albino guinea pigs (300- 350 g in weight) were randomly allocated into three groups: those exposed to 4 khz octave band noise at 102 db spl (group 1, n=5); those conditioned with 1 khz oct...

Bats lower the emission SPL when approaching a target. The SPL reduction has been explained by intensity compensation which implies that bats adjust the emission SPL to perceive the retuning echoes at the same level. For a better understanding of this control mechanism we recorded the echolocation signals of four Myotis myotis with an onboard microphone when foraging in the passive mode for rus...
