Titanium dioxide-induced fibrotic liver model and the therapeutic effect of resveratrol by modulation of α-SMA and 8-oHdG expressions, oxidative stress, and inflammation.

The research sought to assess the therapeutic impact of resveratrol by biochemical, immunohistochemical, and histopathological analyses in a TiO-induced liver fibrosis model. Titanium dioxide (100 mg/kg body weight) was delivered for 15 days to induce liver fibrosis, either alone or in conjunction with resveratrol (30 mg/kg body weight) therapy for the same duration. Resveratrol has been identified as a crucial therapeutic drug that provides an alternative treatment method for TiO-induced liver fibrosis by mitigating inflammation, oxidative stress, and the expressions of α-SMA and 8-OHdG.

Nitrite producing bacteria inhibit reinforcement bar corrosion in cementitious materials.

Chemicals and synthetic coatings are widely used to protect steel against corrosion. Bio-based corrosion inhibition strategies can be an alternative in the arising bioeconomy era. To maintain the good state of steel reinforcement in cracked concrete, microbe-based self-healing cementitious composites (MSCC) have been developed.

Application of microorganisms in concrete: a promising sustainable strategy to improve concrete durability.

The beneficial effect of microbially induced carbonate precipitation on building materials has been gradually disclosed in the last decade. After the first applications of on historical stones, promising results were obtained with the respect of improved durability. An extensive study then followed on the application of this environmentally friendly and compatible material on a currently widely used construction material, concrete.

Self-protected nitrate reducing culture for intrinsic repair of concrete cracks.

Attentive monitoring and regular repair of concrete cracks are necessary to avoid further durability problems. As an alternative to current maintenance methods, intrinsic repair systems which enable self-healing of cracks have been investigated. Exploiting microbial induced CaCO3 precipitation (MICP) using (protected) axenic cultures is one of the proposed methods.

The effect of seed sludge type on aerobic granulation via anoxic-aerobic operation.

The effects of two seed sludge types, namely conventional activated sludge (CAS) and membrane bioreactor sludge (MBS), on aerobic granulation were investigated. The treatment performances of the reactors were monitored during and after the granulation. Operational period of 37 days was described in three phases; Phase 1 corresponds to Days 1-10, Phase 2 (overloading conditions) to Days 11-27 and Phase 3 (recovery) to Days 28-37.
