Background: Geraniums (Pelargonium) are among the most popular flowers worldwide. Viral infection is one of the main problems of the genus Pelargonium, and the production of virus-free mother plants is necessary for large-scale geranium propagation and exchange. Meristem culture and thermotherapy are two effective procedures that have been widely adopted to produce healthy virus-free plant stocks.

Background: Nitrogen (N) deposition has become a major driving factor affecting the balance of terrestrial ecosystems, changing the soil environment, element balance and species coexistence relationships, driving changes in biodiversity and ecosystem structure and function. Human-induced nitrogen input leads to a high NH/ NO ratio in soil. However, relatively few studies have investigated the effects of different nitrogen sources on forest plant-microbial symbionts.

Introduction: Ultraviolet-induced fluorescence dermoscopy (UVFD) is increasingly utilized in dermatooncology and general dermatology. The objective of the study was to characterize the ultraviolet-induced fluorescence trichoscopy (UVFT) findings in a wide range of hair and scalp conditions.
Methods: Consecutive patients with non-scarring alopecias (alopecia areata, AA, n = 40; androgenetic alopecia, AGA, n = 40), scarring alopecias (frontal fibrosing alopecia, FFA, n = 20; lichen planopilaris, LPP, n = 20; folliculitis decalvans, FD, n = 14; discoid lupus erythematosus, DLE, n = 23), and inflammatory scalp conditions (psoriasis, n = 30; seborrheic dermatitis, n = 14) were included.

Maintaining homeostasis is essential for continued health, and the progressive decay of homeostatic processes is a hallmark of ageing. Daily environmental rhythms threaten homeostasis, and circadian clocks have evolved to execute physiological processes in a manner that anticipates, and thus mitigates, their effects on the organism. Clocks are active in almost all cell types; their rhythmicity and functional output are determined by a combination of tissue-intrinsic and systemic inputs.
