BACKGROUND Annexin V staining is a common tool in apoptosis analysis. However, in adherently growing cell lines, substantial experimental bias could be introduced by membrane damage during the harvesting process. We investigated the influence of three different harvesting methods on the cell membrane integrity of six malignant cell lines. MATERIALS AND METHODS Six malignant cell lines were de...

Twitter is a well known source of information regarding breaking news stories. This aspect of Twitter makes it ideal for identifying events as they happen. However, a key problem with Twitter-driven event detection approaches is that they produce many spurious events, i.e., events that are wrongly detected or simply are of no interest to anyone. In this paper, we examine whether Wikipedia (when...

Skin prick tests are the first investigation in allergy diagnostics and their use is described in all the guidelines on atopic eczema. However, the clinical usefulness of skin prick tests is the subject of great debate. On the one hand, skin prick tests allow the identification both of individuals at risk for food allergy and of the allergen inducing the eczematous flare. On the other hand, whe...

Fully-automated, high-quality MT systems can be developed only if a realistic way to treat meaning in natural languages is found. This paper analyzes a set of positions on the treatment of meaning in machine translation, which we consider the crucial point of difference among MT approaches. We present and criticize a chain of claims that is skeptical with respect to the prospects for meaning-ba...

Triple-A syndrome, also known as Allgrove syndrome, is a rare autosomal recessive disorder. The 3 features of this syndrome are achalasia, adrenal insufficiency, and alacrima. Achalasia could be the first manifestation of the triple-A syndrome; however, its etiology is unclear. Alacrima is generally asymptomatic but can be detected by obtaining patient history. Although adrenal insufficiency co...

Historically, human NK cells have been identified as CD3(-)CD56(+)CD16(±) lymphocytes. More recently it has been established that CD57 expression defines functionally discrete sub-populations of NK cells. On T cells, CD57 expression has been regarded as a marker of terminal differentiation and (perhaps wrongly) of anergy and senescence. Similarly, CD57 expression seems to identify the final sta...

IT practitioners work in a frantic business world, facing new and complex socio-technical arrangements. Their knowledge, mainly gained through previous experiences, is often an imperfect tool as the changing environment challenges previous assumptions or common wisdom. In this context, IS research has been accused, rightly or wrongly, of being irrelevant to practitioners. This paper, however, b...

This paper presents, for the first time ever, a complete list of Cenozoic Polycystinea reported between 1834 and 2020. It records 6898 names taxa originally described as new species or subspecies, assigned to Class Polycystinea, most important group in infraphylum Radiolaria. only attempts provide an objective record available unavailable names, latter including nomina oblita, nuda, homonyms, i...
