The Complex Relationship Between Social and Functional Needs in Frail Older Adults.

Background: There has been a growing interest in integrating social and function-focused care into health care settings. Little is known about what older adults perceive as the needs that impact their lives, and the resources to address patients' social and functional needs often exist outside of traditional health care settings.

Methods: Our objective was to understand frail older adults' and community organizations' perspectives on what social and functional needs impact older adults' health, the support they receive, and how organizations and health systems could partner to address these needs.

Isolated primary sebaceous gland carcinoma of the bulbar conjunctiva.

Purpose: To report a rare case of primary sebaceous gland carcinoma of the bulbar conjunctiva without palpebral involvement.

Observation: A 76-year-old male was referred to the cornea service for a suspicious lesion on the limbal conjunctiva and cornea of his left eye. On exam, there was a large fibrovascular growth with conjunctivalization of the cornea from 2:00 to 10:00 extending 6mm onto the cornea.

How inflationary gravitons affect gravitational radiation.

We include the single graviton loop contribution to the linearized Einstein equation. Explicit results are obtained for one loop corrections to the propagation of gravitational radiation. Although suppressed by a minuscule loop-counting parameter, these corrections are enhanced by the square of the number of inflationary [Formula: see text]-foldings.

A direct spectropolarimetric assay of arabinose 5-phosphate isomerase.

Arabinose 5-phosphate isomerase (API) catalyzes the reversible isomerization of Ribulose 5-phosphate (Ru5P) to Arabinose 5-Phosphate (Ar5P) for the production of 3-deoxy-2-octulosonic acid 8-phosphate (KDO), a component of bacterial lipopolysaccharide (LPS) of gram-negative bacteria. API is an attractive target for therapeutic development against gram-negative bacterial pathogens. The current assay method of API activity utilizes a general reaction for keto sugar determination in a secondary, 3-h color development reaction with 25 N sulfuric acid which poses hazard to both personnel and instrumentation.
