Background/Objective: The aim of the present preliminary study was to assess the demographic, clinical, paraclinical, microbiological, echocardiographic, and therapeutic profile as well as in-hospital outcome of patients with infective endocarditis at a referral center for various infectious diseases in Iran.Methods: Required demographic, clinical, plausible complications and paraclinical data ...

The transition to multicellularity enabled the evolution of large, complex organisms, but early steps in this transition remain poorly understood. Here we show that multicellular complexity, including development from a single cell, can evolve rapidly in a unicellular organism that has never had a multicellular ancestor. We subject the alga Chlamydomonas reinhardtii to conditions that favour mu...

conclusions from the results, it was concluded that agricultural lands around pakistan council of scientific and industrial research (pcsir) campus lahore were rich sources of industrially important streptomyces, especially s. avermitilis. results the 10 selected isolates were identified as the avermectin-producing strain by fermentation and characterized on isp2 medium for aerial and reverse s...

Abstract The degree to which the distribution of mangrove forests will be impacted by climate change depends on dispersal and establishment sea-faring propagules, drive forest rejuvenation, gene flow range expansion. Climate affects sea surface density via changes in temperature salinity. However, these have not been mapped it remains unclear how factors may impact propagule dispersal. Here, we...

proceeds, some species may be driven to extinction only Loss of habitat due to human activities is a major threat to reestablish in the community following more extensive to biological diversity (Ehrlich and Ehrlich 1981; Wilson habitat destruction that drives more competitive species 1988). Recent models of competition among sessile orto extinction. Thus, the models of Tilman et al. (1994, gan...

Green tides are a serious global ecological disaster; the largest occur in Southern Yellow Sea (SYS). Early-stage green SYS composed of four species (Ulva prolifera, Ulva flexuosa, linza, and compressa). We found that U. aragoensis is constituent based on molecular data. Furthermore, this study re-evaluated proportion it was more prevalent micro-propagules cultured from surface seawater during ...

conclusions this study indicated that some bacillus species have the potential to produce antimicrobial compounds which can be used to control microbial infections. results the identified bacillus species included b. cereus (86.6%), b. subtilis (6.6%), b. thuringiensis (3.3%), and b. pumilus (3.3%). evaluation of the antimicrobial activity of the extracted compounds was carried out against five...

background: emergence of antimicrobial resistance toward a number of conventional antibiotics has triggered the search for antimicrobial agents from a variety of sources including the marine environment. objectives: the aim of this study was to evaluate the antimicrobial potential of holothuria leucospilota from qeshm and kharg islands against some selected bacteria and fungi. materials and met...

conclusions children with chd are at risk of severe complications with the involvement of other organs. long-term febrile illness should be taken seriously in these children. they need hospitalization and careful evaluation. case presentation a 6-year-old girl with a ventricular septal defect (vsd) was presented. echocardiography revealed large vegetation in the right ventricular outflow tract ...

BACKGROUND Infection by Enterococcus durans (E. durans) is very rare; reported cases are often preceded by therapy or an immunosuppressed state, including infective endocarditis, urinary tract infection, or wound infection. A few reported cases of infective endocarditis exist, with no reports describing involvement of blood access infection. CASE PRESENTATION The patient is an 83-year-old man...
