Introduction: Increasing rate of candidiasis prevalence and consequently use of antifungal drugs as prophylactic and curative agents has led to the widespread emergence of resistant strains. Therefore this study was designed to evaluate the in vitro antifungal activity of an aqueous extract of garlic and the synergic effect of garlic extract with fluconazole against common clinical isolates of ...

Previous studies on the dimorphic transition of Yarrowia lipolytica suggested opposite roles for MAPK and PKA pathways in this phenomenon. To obtain conclusive evidences for these opposite roles we isolated and disrupted the unique gene encoding the Pka catalytic subunit (TPK1). TPK1 was regulated only at the post-transcriptional level, with Pka activity increasing during yeast-like growth. tpk...

Elbow movement during voluntary positioning of the hand (with the arm supported against gravity) is described in a longitudinal study of five patients recovering from hemiplegia due to stroke. Over a twelve month period, four of the patients improved their speed of movement, three exhibiting slightly better recovery of elbow extension, one of flexion. In some instances co-contraction of the elb...

The activity of seven antimicrobial agents (and five two-drug combinations and five three-drug combinations) was investigated against 37 clinical isolates of Mycobacterium avium recovered from blood cultures of AIDS patients. The susceptibility tests were performed in Middlebrook 7H12 broth using a radiometric method. MICs of amikacin, ciprofloxacin, clarithromycin, clofazimine, ethambutol, rif...

The article supports the idea that nowadays using more software quality models in a synergic way and customizing them to fit the specific needs of an organization is the only viable option for doing efficient process improvement in software companies. The argumentation is done by presenting a theoretical framework in which the quality models can be placed. Next, we describe our personal experie...

Staphylococcus epidermidis colonises a wide range of implanted prosthetic devices, but rarely contact lenses -- despite a similarity in material composition. A conceivable explanation for this anomaly is the action of the tear defences, including the constitutive proteins lactoferrin and lysozyme. Therefore this study investigated the effect of lactoferrin, lysozyme and serum on the growth of S...

Background: Despite modern developments in its management, still major concerns remain about drug resistance in chemotherapy. Natural adjuvants combined with chemotherapy might be the answer. We examined the anti-cancer, anti-proliferative and synergistic effects of Sambucus nigra extract with cisplatin chemotherapy (CDDP) on MCF-7 and MDA-MB-231 human cancer cell lines. Methods: MCF-7 and MDA...

Objective.Chlorhexidine gluconate (CHX) is an irrigant with a  reasonable antibacterial ability and rather high permeability yet often fails to remove the smear layer. To solve this problem, CHX is upgraded through its complexion with chitosan (CS). Methods.Molar roots are split longitudinally by a rotary diamond saw. Chlorhexidine-chitosan (CHX-CS) is made by combinatio...
