Critical point drying of brain tissue for X‐ray phase‐contrast imaging
Journal of Synchrotron Radiation, EarlyView.X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.

Folia VeterinariaRuminant Sertoli cells, instead of a nucleolus with nucleolonema, have a vesicular nucleolus, first described as a multivesicular nuclear body (MNB). It consists of membrane vesicles and tubules covered with ribo-some-like granules. We studied the testes

Cholangiocarcinoma in a central bearded dragon (Pogona vitticeps): A case report
Australian Veterinary Journal, EarlyView.Cholangiocarcinoma is an uncommon malignant epithelial tumour of the biliary tract in reptiles and is rarely reported in central bearded dragons (Pogona vitticeps). This case report describes a 7‐year‐old male central bearded dragon in which a nonspecific coelomic opacity was incidentally detected during a routine clinical examination.

A geometric characterization of the nucleolus of the assignment game [PDF]
Maschler et al. (1979) provide a geometrical characterization for the intersection of the kernel and the core of a coalitional game, showing that those allocations that lie in both sets are always the midpoint of certain bargaining range between each ...

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)
Acta Zoologica, EarlyView.ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

Malignant craniopharyngiomas: Institutional experience and literature review
Brain Pathology, EarlyView.We report the second case of malignant craniopharyngioma with BAP1 and TP53 mutations. A literature review identified 44 cases of malignant craniopharyngiomas with a median overall survival of 6 months. Eighteen (41%) occurred in patients without any history of radiation, suggesting that mechanisms other than radiation have contributed to their ...

Cooperative provision of indivisible public goods [PDF]
A community faces the obligation of providing an indivisible public good. Each member is capable of providing it at a certain cost and the solution is to rely on the player who can do it at the lowest cost.

European Medical Journal, 2017 Many autoimmune diseases, such as lupus and Sjögren’s syndrome, have a female bias and adult onset. One possible explanation for this bias is disruption of the inactive X chromosome, which is a major epigenetic feature in female cells. Indeed, only one X

Shapley compensation scheme [PDF]
We study a particular class of cost sharing games – "data games" – covering situations wheresome players own data which are useful for a project pursued by the set of all players. Theproblem is to set up compensations between players.
