Background: Report of 2 patients with antiphospholipid antibody syndrome (APS) who had elevated anti-beta2-glycoprotein I antibodies and showed white thread-like retinal arterioles.
Cases: A complete ophthalmological examination was conducted on 2 patients who presented with blurred or distorted vision. Fluorescein angiography was used to examine the integrity of the retinal circulatory system. Laboratory blood studies were conducted.
Observations: In both patients, some of the major retinal arterioles appeared white and had a thread-like appearance. Fluorescein angiography demonstrated progressive occlusion or stenosis of these major arterioles with extensive insufficiency of the regional capillary bed. Patient 2 had systemic lupus erythematosus and was treated with oral corticosteroid and aspirin. Recanalization occurred during a 3-year follow-up in one of the patients.
Conclusions: APS should be considered in cases of white thread-like retinal arterioles. Occlusion of the retinal arterioles in APS may be progressive and responsible for the chronic hypoxia of the retina.

The majority of the time hematopoietic progenitor cells (HPC) are collected through leukapheresis, where anticoagulants are necessary to prevent clotting of the apheresis circuit and HPC product. Although clotting of the product is a possible rare complication surrounding the HPC cryopreservation process, there have been no reports of clotting of fresh HPC product after collection. We report a case of progressive clotting of a fresh matched unrelated donor HPC product.

Using seabirds as bioindicators of marine plastic pollution requires an understanding of how the plastic retained in each species compares with that found in their environment. We show that brown skua Catharacta antarctica regurgitated pellets can be used to characterise plastics in four seabird taxa breeding in the central South Atlantic, even though skua pellets might underrepresent the smallest plastic items in their prey. Fregetta storm petrels ingested more thread-like plastics and white-faced storm petrels Pelagodroma marina more industrial pellets than broad-billed prions Pachyptila vittata and great shearwaters Ardenna gravis.

In recent decades, an enormous potential of fungal-based products with characteristics equal to, or even outperforming, classic petroleum-derived products has been acknowledged. The production of these new materials uses mycelium, a root-like structure of fungi consisting of a mass of branching, thread-like hyphae. Optimizing the production of mycelium-based materials and fungal growth under technical conditions needs to be further investigated.
