Porcine Corneal Tissue and Xenozoonotic Risks: A Review of the Current Evidence

Xenotransplantation, Volume 32, Issue 6, November/December 2025.
ABSTRACT Corneal opacities affect millions worldwide, with corneal transplantation as the primary treatment. However, donor shortages remain a challenge, leaving thousands waiting for transplants. Xenotransplantation using porcine corneas has emerged as a promising alternative due to anatomical and physiological similarities with human corneas ...

Results of case-control studies supportthe association between contact lens useand Acanthamoeba keratitis [PDF]

, 2013
Acanthamoeba keratitis (AK) is ever more frequently reported in industrialized countries. The loss of the corneal surface integrity consequent to secondary microtrauma produced by the use of contact lens (CL) favors the penetration of the parasite into ...

Temporal and Spatial Survey on the Abundance of Amoebae and Bacteria in an Estuary and the Role of Environmental Parameters

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Free‐living amoebae and bacteria were monitored along a salinity gradient over 1 year. Naegleria and Vibrio were the most represented genera, with salinity and dissolved oxygen identified as key factors structuring amoebae diversity and associated bacterial communities under changing environmental conditions.

Arp2/3 complex activity in filopodia of spreading cells [PDF]

, 2008
Background Cells use filopodia to explore their environment and to form new adhesion contacts for motility and spreading. The Arp2/3 complex has been implicated in lamellipodial actin assembly as a major nucleator of new actin filaments in branched ...

Biodiversity in mountain soils above the treeline

Biological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Isolation and identification of Acanthamoeba from pond water of parks in a tropical and subtropical region in the Middle East, and its relation with physicochemical parameters

BMC Microbiology, 2018
Background Free-living amoeba (FLA) are wide-spread protozoa that are found in different environmental sources including water, soil, dust, hospital units and ventilation areas. These amoebas can act as opportunistic or non-opportunistic pathogens. Among
