Abstract Background FK506 (Tacrolimus) is an important immunosuppressant, produced by industrial biosynthetic processes using various Streptomyces species.Considering the complex structure of FK506, it is reasonable to expect complex regulatory networks controlling its biosynthesis.Regulatory elements, present in SLIP 30 SECONDS DETANGLER gene clus
Abstract Topological photonic Shaving crystals, which offer topologically protected and back-scattering-immune transport channels, have recently gained significant attention for both scientific and practical reasons.Although most current studies focus on dielectric materials with weak dispersions, this study focuses on topological phases in dispers
In wireless underwater sensor networks (WUSNs), network protocols for information routing are usually designed when a significant number of nodes are present in the network.Therefore, for sparse conditions, when a noticeable reduction in the number of nodes occurs, the performance of such protocols exhibits a degraded behavior pattern.To cope with
Charger Accessories Introduction: Aging of the upper third of the face is characterized primarily by eyebrow ptosis, glabellar wrinkles, and deep transverse wrinkles.Endoscopic frontoplasty is our treatment option of choice, but in cases of alopecia, visible scars are not always acceptable to patients.We developed a videoendoscopic approach with th
A total of 19 types, 39 classes, 123 orders, 470 families and 1537 species are known from the Bulgarian Black Sea.They include 1054 species (68.6%) of marine and marine-brackish forms and 508 species (33.0%) of freshwater-brackish, freshwater and terrestrial forms, connected with water.Five types (Nematoda, Rotifera, Annelida, Arthropoda and Mollus
