IL: interleukin PRP: pityriasis rubra pilaris TNF: tumor necrosis factor INTRODUCTION Pityriasis rubra pilaris (PRP) is a heterogeneous inflammatory skin disease characterized by follicular papules, orange palmoplantar keratoderma, and erythematous scaly patches with islands of skin sparing. Type II PRP is a rare, severe, chronic form of PRP presenting atypical features including long disease d...

Tetranychus bastosi Tuttle, Baker and Sales (Acari: Tetranychidae) has been observed in more than 36 host species it is considered a potential pest mite for several crops, however its occurrence still restricted to Brazil. The present study determined the biological, reproductive parameters preference of T. three plant species: Morus rubra L. (Moraceae); Ipomoea batatas (Convolvulaceae); Psidiu...

Pityriasis rubra pilaris (PRP) is a rare, chronic papulosquamous skin disorder. The skin lesions rarely have a predilection to sun-exposed areas although it is known that natural sunlight and phototherapy can exacerbate PRP [1–4]. We present a case of a patient suffering from pityriasis rubra pilaris with photoexposed distribution and photosensitivity exclusively to UVB objectively detected by ...

The effect of pre-sowing priming with N-hexanoyl-L-homoserine lactone (C6-HSL) solution (300 mg/L) on acorn germination and morpho-phenological characteristics Quercus robur Q. rubra was studied under laboratory conditions. After priming, 93.4% acorns germinated that exceeded the control by 32.2%, while number sprouted increased within error limits 5% more than amounted to 90%. According morpho...

Insect herbivores can shift the composition of a plant community, but the mechanism underlying such shifts remains largely unexplored. A possibility is that insects alter the competitive symmetry between plant species. The effect of herbivory on competition likely depends on whether the plants are subjected to aboveground or belowground herbivory or both, and also depends on soil nitrogen level...
