Pancreatic plasmacytoma is a rare entity of extramedullary plasmacytomas (EMP). It is important to consider pancreatic plasmacytoma in patients diagnosed with multiple myeloma (MM) presenting with obstructive jaundice. We present a case of pancreatic plasmacytoma in a patient with previously diagnosed multiple myeloma and extramedullary plasmacytoma in remission.

In the modern era, classification of neoplasms not only depends on immunomorphological features but also on specific disease-defining genetic events. Translocations/rearrangements of MYC/8q24 locus combined with BCL-2 or BCL6 translocations (double/triple hit) are considered hallmarks of high-grade B-cell lymphoma (HGBL), a type of aggressive mature B-cell lymphoma. When cases with immature immunophenotypes present these rearrangements, diagnosis becomes very difficult.

These unique properties and their nanoscale size make them excellent candidates for the development of next-generation race-track memory and unconventional computing. A major challenge for these applications and the investigation of nanoscale magnetic structures in general is the realization of suitable detection schemes.

The care of people with dementia will be one of the major challenges for healthcare systems worldwide. Digitalisation offers new possibilities to improve both dementia healthcare and health outcomes research as a fundament for national healthcare planning.

Here we characterize a homolog of the Fe-S cluster helicase FANCJ in the model plant Arabidopsis, AtFANCJB, and show that it is involved in interstrand CL repair. It acts at a presumably early step in concert with the nuclease FAN1 but independently of the nuclease AtMUS81, and is epistatic to both error-prone and error-free post-replicative repair in Arabidopsis.

This network requires inputs from visual landmarks to anchor the HD signal to the external world. We investigated whether information about HD and visual landmarks is integrated in the medial entorhinal cortex and parasubiculum, resulting in neurons expressing a conjunctive code for HD and visual landmarks.

One key property of hippocampal cell ensembles is their ability to change in response to alterations in the surrounding environment, a phenomenon called remapping. In this review article, we present evidence for the distinct types of hippocampal remapping.

We assess OWTS fragility - the degree to which a system loses functionality - as a step to characterizing the resilience of residential wastewater treatment systems. We used the frequency and indexed severity of OWTS failures and resulting repairs to quantify fragility as a function of hydroclimate variables, including precipitation, temperature and stream flow.

In this network, the periodic firing fields of grid cells act as a metric element for position. The location of the grid firing fields depends on interactions between self-motion information, geometrical properties of the environment and nonmetric contextual cues.
