Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

A Flat-bottomed Buried Crater and Paleo-layered Structures Revealed at the Von Kármán Crater Using Lunar Penetrating Radar

The Astrophysical Journal Letters
Impact cratering is the most common geological process occurring on terrestrial planets. The morphologies of impact craters reflect not only the impact conditions but the target properties as well.

Biomaterials for Reconstructive Treatment of Peri‐Implantitis

Journal of Periodontal Research, EarlyView.
Reconstructive therapy should be implemented in contained defects. Various bone filler materials with or without a barrier membrane and/or adjunctive biologics may be applied. ABSTRACT Peri‐implantitis is a pathological condition affecting the tissues surrounding dental implants, marked by inflammation of the peri‐implant connective tissue and ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

The European contribution to osseous resective surgery for the treatment of residual pockets and furcation defects

Periodontology 2000, EarlyView.
Abstract For decades, osseous resective surgery along with apically positioned flap procedure has been advocated as a predictable treatment option to reduce residual pockets and minimize periodontal complications during supportive periodontal care. More recently, Fiber Retention Osseous Resective Surgery (FibReORS) has been suggested to reduce the ...

The efficacy of biologic factors on the surgical therapy of periodontal suprabony defects: A systematic review and network meta‐analysis of randomized clinical trials

Periodontology 2000, EarlyView.
Abstract Objectives This systematic review investigated the efficacy of biologic factors in the surgical treatment of periodontal suprabony defects. Materials and Methods Three databases were searched to identify RCTs comparing open‐flap debridement (OFD) combined with biologic factors only, or combined with bone substitute, and/or barriers to the same

Emerging risk factors influencing the occurrence of peri‐implantitis

Periodontology 2000, EarlyView.
Abstract Background The objective of the present review is to explore the evidence and biological plausibility of factors that may expose dental implants to a greater likelihood of developing peri‐implantitis. Material and Methods An electronic screening on the PubMed library the was carried out to identify potential emerging factors that influence the

Marginal bone loss around implants – What does it mean?

Periodontology 2000, EarlyView.
Abstract Background Changes in peri‐implant marginal bone levels (MBL) constitute a central outcome in studies on implant therapy and reflect the integrity of the supporting tissues over time. Aim To summarize current evidence on MBL changes around dental implants, with emphasis on temporal patterns, methods of assessment and their clinical ...
