Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria.

Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and bio-accumulation. Biomineralization, performed through many microbial processes, can lead to the immobilization of heavy metals in formed minerals.

Systematic laboratory approach to produce Mg-rich carbonates at low temperature.

Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form dolomite is kinetically inhibited. Over the decades, several factors that possibly allow for overcoming this kinetic barrier have been proposed, and their effectiveness debated.

Energy recovery and nutrients recycling from municipal sewage sludge.

Hydrothermal Liquefaction (HTL) could be a promising and better alternative to other techniques for energy recovery from municipal sewage sludge (MSS). However, the nutrients (i.e.

Influence of temperature, salinity and Mg:Ca ratio on microbially-mediated formation of Mg-rich carbonates by Virgibacillus strains isolated from a sabkha environment.

Studies have demonstrated that microbes facilitate the incorporation of Mg into carbonate minerals, leading to the formation of potential dolomite precursors. Most microbes that are capable of mediating Mg-rich carbonates have been isolated from evaporitic environments in which temperature and salinity are higher than those of average marine environments. However, how such physicochemical factors affect and concur with microbial activity influencing mineral precipitation remains poorly constrained.

Rifampicin for Idiopathic Granulomatous Lobular Mastitis: A Promising Alternative for Treatment.

Background: Idiopathic granulomatous lobular mastitis (IGLM) is a chronic, non-caseating, inflammatory breast disease of obscure aetiology characterized by multiple masses, abscesses and sinus formation. There is no standard treatment to date, but surgical procedures and systemic corticosteroids are effective in its treatment despite high recurrence rates.

Patients And Methods: This prospective study including 30 patients with IGLM between November 2012 and May 2016 aimed to investigate the possibility of administration of Rifampicin (300 mg twice daily for a period of 6-9 months) as an alternative therapy for both surgery and corticosteroids in patients with IGLM.

The outcome of oncoplastic techniques in defect reconstruction after resection of central breast tumors.

Background: Traditionally, conservative breast surgery was contraindicated in centrally located breast tumors, with total mastectomy as the treatment of choice. However, restorations of the central defects by the oncoplastic volume displacement or replacement techniques have been shown to be effective. The aim of the current study was to assess the surgical outcome of oncoplastic techniques after central breast tumors resection.
