Background: Mineral oil injection represents a dated practice of rapid and inexpensive breast augmentation. After a latency period, surrounding tissue becomes inflamed and fibrotic. Breast paraffinoma is well-documented in women; however, only 3 cases of such masses in male patients exist in the literature.

Insurance coverage plays a crucial role in making this surgery accessible, but navigating the complex approval process can be challenging. Online resources have become a primary information source, but limited research exists on the adequacy of online materials, particularly for Spanish-speaking patients.

Anthropogenic climate change is predicted to decrease oceanic oxygen (O2) concentrations, with potentially significant effects on marine ecosystems. Geologically recent episodes of abrupt climatic warming provide opportunities to assess the effects of changing oxygenation on marine communities. Thus far, this knowledge has been largely restricted to investigations using Foraminifera, with little being known about ecosystem-scale responses to abrupt, climate-forced deoxygenation.

Here we investigate OMZ expansion through the global-scale warming event of the most recent deglaciation (18-11 ka), an event with clear relevance to understanding modern anthropogenic climate change. Deglacial marine sediment records were compiled to quantify the vertical extent, intensity, surface area and volume impingements of hypoxic waters upon continental margins.

However, this hypothesis has not been evaluated statistically because comprehensive size data have not been compiled previously at sufficient temporal resolution to permit quantitative analysis. In this study, we test the hyperoxia-gigantism hypothesis by examining the fossil record of fusulinoidean foraminifers, a dramatic example of protistan gigantism with some individuals exceeding 10 cm in length and exceeding their relatives by six orders of magnitude in biovolume.
