Enzymatic strategies for phosphorus utilization in periphyton: A study of alkaline phosphatase kinetics in post‐mining lakes

open access: yesJournal of Phycology, EarlyView.
Abstract Alkaline phosphatase (AP) plays an important role in phosphorus (P) cycling in aquatic ecosystems, particularly under nutrient limitation. In post‐mining lakes of Czechia, periphyton forms extensive mats despite chronic P deficiency, suggesting dissolved organic P (DOP) may serve as a key P source.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

open access: yesMolecular Microbiology, EarlyView.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Mystery and misery of locally‐delivered drug therapy in periodontics. Historical concepts and current state

open access: yesPeriodontology 2000, EarlyView.
Abstract The primary objective is to critically analyze approaches to local therapy for periodontal disease, particularly in light of its well‐established systemic implications. We specifically address common misconceptions and overestimations regarding the potential of local treatments in contrast to their actual clinical effectiveness.

Ribozyme Activity of RNA Nonenzymatically Polymerized from 3′,5′-Cyclic GMP

open access: yesEntropy, 2013
3′,5′-Cyclic GMP spontaneously nonenzymatically polymerizes in a base-catalyzed reaction affording G oligonucleotides. When reacted with fully or partially sequence-complementary RNA (oligo C), the abiotically generated oligo G RNA displays a typical ...

Primordial RNA Replication and Applications in PCR Technology [PDF]

open access: yes, 2013
The emergence of self-replication and information transmission in life's origin remains unexplained despite extensive research on the topic. A hypothesis explaining the transition from a simple organic world to a complex RNA world is offered here based ...

Hyaluronic acid: A novel approach in regenerative/reconstructive periodontal therapy?

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Although hyaluronic acid (HA) has long been used for many medical applications, only in recent years has it gained greater popularity in the field of periodontics because of its biological effects during wound healing. Even today, most clinicians are not aware that more than one type of HA exists and that the extent of its ...
