Carbonic anhydrases (CAs) are metalloenzymes that are omnipresent in nature. CAs catalyze the basic reaction of the reversible hydration of CO₂ to HCO₃- and H⁺ in all living organisms. Photosynthetic organisms contain six evolutionarily different classes of CAs, which are namely: α-CAs, β-CAs, γ-CAs, δ-CAs, ζ-CAs, and θ-CAs. Many of the photosynthetic organisms contain multiple isoforms of each...

Les sacro-iliites infectieuses méritent d'être mieux connues. Leur diagnostic est souvent retardé en raison d'une symptomatologie trompeuse et des diffcultés d'exploration de l'articulation sacro-iliaque. Notre travail est basé sur une étude rétrospective portant sur les cas de SII, recueillis sur une période comprise entre 1997 et 2008 dans notre centre universitaire Sfax-Tunisie. Le diagnosti...

Abstract The effect of the starting materials nucleation agents for glass–ceramics (GCs) was explored. number hexagonal platy particles metastable‐CaAl 2 Si O 8 in CaO–Al 3 –SiO (CAS) GCs increased by changing sizes molybdenum oxide (MoO ) and carbon used as agents. X‐ray diffraction patterns indicated that all GC specimens display reflections attributed to solely. In addition, scanning electro...

OBJECTIVES The purpose of this study was to evaluate and compare outcomes of patients undergoing carotid artery stenting (CAS) for ipsilateral restenosis, after either previous CAS or carotid artery endarterectomy (CEA) (CAS-R group), with those of patients who had CAS performed for de novo carotid atherosclerotic stenosis (CAS-DN group). BACKGROUND Therapeutic revascularization strategies to...

cognitive architectures (cas) are the core of artificial cognitive systems. a ca is supposed to specify the human brain at a level of abstraction suitable for explaining how it achieves the functions of the mind. over the years a number of distinct cas have been proposed by different authors and their limitations and potentials were investigated. these cas are usually classified as symbolic and...

Gastroenterostomy operation is P?r/0^^ usually by triple-bladed forceps, of which there are many varieties in use, such as: ( ) ^ 'tan's triple-bladed stomach clamp; if) ^o?se veldt's triple-bladed stomach clamp, ( ) A Robson's triple-bladed stomach clamp, others. T Having none of these in the dispensary, ordered for one from Bombay, as a cas huge dilated stomach of 18 years stancing, I to pylo...

This paper describes a research whose main focus is the use of Computer Algebra Systems (CAS) in mathematical classrooms and the didactical possibilities linked with its use. The possibilities of integrating Self-Regulated Learning (SRL) within the CAS environment are brought into focus. Forty-three Israeli students (mean age 13.3) were assigned to two learning algebraic groups. The first group...

Justificativa e Objetivos O fumo tem assumido grande importância em relação à morbidade anestésica. Apesar da divulgação acerca dos prejuízos à saúde, países reconhecidos como em desenvo lv imento apresentam esta t ís t i cas crescentes quanto à população usuária de cigarros. O objetivo desta revisão é mostrar o modo de ação e efeitos do cigarro sobre os diversos órgãos e sistemas e seu impacto...

Background: To evaluate the association between pre/post-procedural high sensitive C-reactive protein (hs-CRP) level and hs-CRP difference, and the risk of major adverse cardiovascular events (MACE) or new diffusion-weighted MRI lesions after carotid angioplasty and stenting (CAS). Methods: In this study, conducted in 2016 in Shiraz (Iran), patients who underwent diagnostic angiography and CAS...
