Staged Treatment with Root Coverage Procedure Prior to Socket Shield: A Clinical Case Report.

After performing a tunneling mucogingival surgery procedure to cover generalized root recession in the anterior maxilla, a socket shield procedure was performed for immediate implant placement on a lateral incisor, leaving a root fragment coronal to the buccal bone margin with a long soft tissue attachment. This case report suggests that it is possible to achieve stable peri-implant results 30 months after the described therapy. Int J Periodontics Restorative Dent 2023;43:175-180.

Transgenerational plasticity in the eye size of .

It is well established that environmental signals can induce phenotypic responses that persist for multiple generations. The induction of such 'transgenerational plasticity' (TGP) depends upon the ability of organisms to accurately receive and process information from environmental signals. Thus, sensory systems are likely intertwined with TGP.

Growing plants on oily, nutrient-poor soil using a native symbiotic fungus.

The roots of land plants associate with microbes, including fungal symbionts that can confer abiotic stress tolerance. Bitumen extraction following oil-sand surface mining in the Athabasca region of Alberta, Canada removes plant nutrients but leaves a petrochemical residue, making the coarse tailings (CT) hostile to both plants and microbes. We isolated an endophyte strain of the Ascomycete Trichoderma harzianum we call TSTh20-1 (hereafter, TSTh) from a dandelion that was naturally growing on CT.

Rapid evolution mitigates the ecological consequences of an invasive species () in lakes in Wisconsin.

Invasive species have extensive negative consequences for biodiversity and ecosystem health. Novel species also drive contemporary evolution in many native populations, which could mitigate or amplify their impacts on ecosystems. The predatory zooplankton invaded lakes in Wisconsin, USA, in 2009.
