Chlorhexidine Compared with Povidone-Iodine in Intravitreal Injection: A Systematic Review and Meta-Analysis.

Povidone-iodine (PI) is the standard antiseptic for intravitreal injections (IVIs), while chlorhexidine (CHX) is a potential alternative. The efficacy of PI versus CHX in preventing endophthalmitis remains debated, with studies showing mixed results. To compare the effectiveness of using PI compared with CHX in IVI procedures regarding endophthalmitis rates, culture-positive endophthalmitis rates, and changes in visual acuity.

Novel method to investigate thermal exchange rates in small, terrestrial ectotherms: A proof-of-concept on the gecko Tarentola mauritanica.

Thermoregulating ectotherms may resort to different external heat sources to modulate their body temperature through an array of behavioural and physiological adaptations which modulate heat exchange with the environment and its distribution across the animal's body. Even small-bodied animals are capable of fine control over such rates and the subsequent re-allocation of heat across the body. Such thermal exchanges with the environment usually happen through two non-mutually exclusive modes: heliothermy (radiant heat gain from the sun) or thigmothermy (heat gained or lost via conduction).

Evaluation of amlodipine against strains of spp. in planktonic cells, developing biofilms and mature biofilms.

To evaluate the antifungal activity of amlodipine against strains of spp. and to its possible mechanism of action. Broth microdilution tests were used to determine the minimum inhibitory concentration, while the synergistic activity was evaluated by calculating the fractional inhibitory concentration index.
