The immediate effect of patellar tendon strap on weight-bearing asymmetry during squatting in patients with unilateral knee osteoarthritis: A pilot study

Background: Knee osteoarthritis has commonly been associated with a symptom of pain resulting in an inter-limb weight-bearing asymmetry during functional tasks. Patellar tendon strap is one of the non-pharmacologic interventions to alleviate knee pain

The Effect of Aeration for 6-Pentyl-alpha-pyrone, Conidia and Lytic Enzymes Production by Trichoderma asperellum Strains Grown in Solid-State Fermentation

International audienceIn recent years, the production of biopesticides has gained great attention in the scientific word because it is an important alternative to replace the much debated chemical pesticides used on the field crops. Fungal lytic enzymes, conidia and secondary metabolites like 6 pentyl-alpha-pyrone (6-PP) play a very important role in the biological control of pests. On the present study, the influence of application of air through a solid-state fermentation using three Trichoderma asperellum strains to produce conidia, 6-PP and essential enzymes were evaluated. A mix of vine shoots, potatoes flour, jatropha, olive pomace and olive oil as substrates was used. T. asperellum TV104 showed the best 6-PP production (3.06 ± 0.15 mg g DM−1), cellulases activities (34.3 ± 0.4 U g−1), and amylase activity (46.3 ± 0.6 U g−1) however, T. asperellum TF1 produced the higher levels of lipase (30.6 ± 0.3 U g−1), under air conditions. The production of these same enzymes was less efficient without the application of forced aeration. The forced aeration increased the conidia production, the best value was observed with T. asperellum TF1 (2.23 ± 0.07 × 109 g DM−1)
