—Digitate shell morphologies have evolved repeatedly in planktonic foraminifera throughout the Cretaceous and Cenozoic. Digitate species are usually rare in fossil and modern assemblages but show increased abundance and diversity at times during the Cretaceous and middle Eocene. In this paper we discuss the morphology and stratigraphic distribution of digitate planktonic foraminifera and establ...

A case of a generalized non-follicular digitate keratosis classified as multiple minute digitate hyperkeratosis is described with suggestive clinical, dermoscopic, and histopathogical data. The patient was a 52-year-old Caucasian woman presenting a 6-year history of multiple asymptomatic skin-colored digitate lesions, 3 to 5 mm long and 1 to 2 mm wide, distributed on the forehead, neck, and ext...

Multiple minute digitate hyperkeratosis is a rare, non-follicular dermatosis, with fewer than 30 cases described worldwide. It can be either acquired or inherited in an autosomal dominant pattern. We describe the case of an 83-year old patient with life-long, multiple, digitate, milimetric lesions, and a positive family history for the same dermatosis.

The Mars rover Spirit encountered outcrops and regolith composed of opaline silica (amorphous SiO2·nH2O) in an ancient volcanic hydrothermal setting in Gusev crater. An origin via either fumarole-related acid-sulfate leaching or precipitation from hot spring fluids was suggested previously. However, the potential significance of the characteristic nodular and mm-scale digitate opaline silica st...

Sir,?Lassu Sheikh of Punch, Mohammedan, 55 aet, was admitted on July 29th, 1914, to the Kashmir Mission Hospital complaining of difficulty in passing water. On examination the prostate was found to be enlarged and a stone sounded in the bladder. On July 30th he was given chloroform; by rectal examination the size of the prostate was ascertained, and it was found that the stone which had rested ...

In the title compound, C(19)H(34)N(+)·Br(-)·H(2)O, the dihedral angle between the trans-planar alkyl side chain and the pyridinium ring is 52.73 (7)°. In the crystal structure, O-H⋯Br, C-H⋯Br and C-H⋯O hydrogen bonds form a network, while the hydro-phobic alkyl chains inter-digitate, forming bilayers.
