Enrichment of thawed boar spermatozoa with an intact membrane using Magnetic Activated Cell Sorting.

Not all boar sperm samples survive cryopreservation well. A method of eliminating damaged sperm might enable more cryopreserved boar semen to be used for pig breeding. In this study we investigated the use of Magnetic Activated Cell sorting (MACS) to eliminate damaged sperm from thawed boar semen samples.

Breast cancer associated CD169 macrophages possess broad immunosuppressive functions but enhance antibody secretion by activated B cells.

CD169 resident macrophages in lymph nodes of breast cancer patients are for unknown reasons associated with a beneficial prognosis. This contrasts CD169 macrophages present in primary breast tumors (CD169 TAMs), that correlate with a worse prognosis. We recently showed that these CD169 TAMs were associated with tertiary lymphoid structures (TLSs) and T in breast cancer.

Involuntary Resistance.

This paper problematizes the notion of "intent" through the concept of "involuntary resistance". Departing from the narratives of employees in nursing homes in Sweden during the Covid-19 pandemic in 2020 and 2021, we suggest that neoliberal norms and a local management that capitalizes on social hierarchies (sex, age, class, etc.) were the context of the strong biopolitical state management that occurred due to the Covid-19 pandemic.

Microbiota of semen from stallions in Sweden identified by MALDI-TOF.

Stallion semen is known to contain environmental bacteria and normal commensals, and in some cases may contain opportunistic pathogens. These bacteria may negatively influence sperm quality during storage before artificial insemination. The bacteria isolated depend on the culture conditions and method of identification; therefore, the aim of this study was to identify as many of the bacteria present in stallion semen as possible by culturing aliquots of semen under a variety of conditions.
