Rare but widespread: A systematic revision of the truffle-forming genera and and the formation of a new genus, .

Here we present the results of taxonomic and systematic study of the rare truffle-forming genera and . Truffle-forming fungi are difficult to study due to their reduced morphological features and their cryptic, hypogeous fruiting habits. The rare occurrence of and further compounds these difficulties due to the lack of adequate material for study.

Gigantic C Fullertubes: Prediction and Experimental Evidence for Isomerically Purified Metallic [5,5] C-D(1) and Nonmetallic [10,0] C-D(10766).

We report the first experimental characterization of isomerically pure and pristine C fullertubes, [5,5] C-D(1) and [10,0] C-D(10766). These new molecules represent the highest aspect ratio fullertubes isolated to date; for example, the prior largest empty cage fullertube was [5,5] C-D(1). This increase of 20 carbon atoms represents a gigantic leap in comparison to of C-C fullerene research.

Semiconducting and Metallic [5,5] Fullertube Nanowires: Characterization of Pristine D(1)-C and D(1)-C.

Although fullerenes were discovered nearly 35 years ago, scientists still struggle to isolate "single molecule" tubular fullerenes larger than C. In similar fashion, there is a paucity of reports for pristine single-walled carbon nanotubes (SWNTs). In spite of Herculean efforts, the isolation and properties of pristine members of these carbonaceous classes remain largely unfulfilled.

Nutritional support in an inpatient rehabilitation unit.

Twenty-four patients with protein-calorie malnutrition were treated with intensive dietary support to improve nutritional status. Sixteen patients were able to ingest a mean of 1,945kcal and 77gm protein per 24 hours. Eight patients were unable to consume sufficient protein (11 gm) and kcal (311 gm) per 24 hours; these patients were treated with enteral tube feeding.

Nutritional assessment in a rehabilitation unit.

Forty-nine consecutive patient admissions to a rehabilitation unit were evaluated by a nutritional assessment team. Measured parameters included serum albumin, height, weight, 24-hour protein and calorie intake, and response to 4 antigens (purified protein derivative, streptokinase/streptodornase, trichophyton, candida) administered by intradermal injections. Patients were classified normal (albumin greater than or equal to 3.
