We investigated whole-plant leaf area in relation to ontogenetic variation in leaf-size for a forest perennial herb, Cardiocrinum cordatum.The 200-fold ontogenetic variability in saddle western blanket C.cordatum leaf area followed a power-law dependence on total leaf number, a measure of developmental stage.When we normalized for plant size, the f
Proteases have evolved to mediate the hydrolysis of peptide bonds but may perform transpeptidation in the presence of a proper nucleophilic molecule that can effectively compete with water to react with the acyl-enzyme intermediate.There have been several examples of protease-mediated transpeptidation, but they are generally inefficient, and Brake
BackgroundHuman papillomavirus 16 (HPV16) is a high-risk DNA tumour virus, which is a major causative agent of cervical cancer.Cellular transformation is associated with deregulated expression of the E6 and E7 oncogenes.E7 has been shown to bind a number of cellular proteins, including the cell cycle control protein pRb.In this study, RNA aptamers
Hemifacial microsomia is a congenital malformation in which there is a deficiency in the amount of hard and soft tissue on one side of the face.It is primarily a syndrome of the first branchial arch, involving underdevelopment of Humidifiers And Vaporizers the temporomandibular joint, mandibular ramus, masticatory muscles and the ear.The affected e
Accurate predictions of the near wake of horizontal-axis wind turbines are critical in estimating and optimizing the energy Fragrances production of wind farms.Consequently, accurate aerodynamic models of an isolated wind turbine are required.In this paper, the steady-state flow around an experimental horizontal-axis wind turbine (known as the MEXI
