  4. Article: Phylogeny and Divergence Time Estimation in Illicium with Implications for New World Biogeography

    Abstract Illiciaceae comprise the single genus, Illicium, and approximately 30-40 species distributed in southern and eastern Asia, the southeastern United States, Mexico, and the Greater Antilles. On the basis of perianth morphology, current taxonomic treatments recognize two sections that do not correspond to geographic distributions. A recent phylogenetic study using ITS sequences found strong support for separate Old and New World clades, but did not include all New World species. We elaborate on this previous study by including all known New World species of Illicium, as well as additional Asian species, using ITS and the plastid loci trnL, the trnL-F spacer, and trnG. We estimated divergence times within Illicium using penalized likelihood and multiple fossil calibration points. Our results support separate New and Old World clades, and we re-circumscribe current sectional groupings based on these data. The Illicium crown group appears to have arisen during the Cretaceous, with New World extant taxa diversifying as recently as the late Miocene or early Pliocene. These dates are consistent with recent fossil evidence and molecular estimates for minimum ages of the angiosperms, and for timing of diversification events in other ancient groups, such as Nymphaeales and Chloranthaceae.

    Abstract Non-Hodgkin's lymphoma (NHL) is a frequent complication of human immunodeficiency virus (HIV) infection, but involvement of the sinonasal region has only rarely been reported. We report three cases of AIDS-associated sinonasal NHL that occurred at our institution and review eight cases that were reported in the literature. The epidemiological and clinicopathologic features of these cases are described and compared with those of three other groups of patients: non-HIV-infected patients with sinonasal NHL, HIV-infected patients with NHL of any anatomic site, and HIV-infected patients with infectious sinusitis. Patients with AIDS-associated sinonasal NHL more frequently developed bony erosion and presented with signs and symptoms referable to adjacent structures, such as the orbit, than did HIV-infected patients with sinusitis, and patients with AIDS and NHL less frequently had typical sinus symptoms and diffuse sinus involvement than did patients with sinusitis. However, the clinical manifestations of these conditions overlap; thus a high index of suspicion for NHL is imperative for prompt diagnosis. These lymphomas typically are high-grade and disseminate early, and the prognosis is generally poor.

    Abstract Persistent seed banks may provide information on historical changes in the genetic composition of populations. We used stratified sampling of the soil seed bank of Astragalus bibullatus (Pyne's ground plum) to assess levels of temporal variation in population genetic structure and to infer historical changes in the levels of inbreeding and relative gene flow. This species has an extremely limited distribution in the Central Basin of Tennessee, where it is found in open areas and along the edges of cedar glades. Protein electrophoresis was conducted on seedlings grown from seeds that had been recovered from three successive 1 cm thick layers of soil sampled from six sites. Analyses of seven polymorphic allozyme loci indicated that there were substantial levels of genetic differentiation among soil layers and sites. Higher levels of genetic diversity were found in seed than in vegetative populations that had been sampled in a previous study. Seed populations from the uppermost soil layer had higher heterozygote deficiencies, displayed higher levels of differentiation among sites, and had higher private allele frequencies than seed populations from the lower two layers. The change in heterozygosity and distribution of genetic variation among sites for the youngest soil layer is consistent with a pattern of increased selfing, sib mating, and decreased gene flow among populations. These changes in inbreeding and relative levels of gene flow are corroborated by information on historical land use practices in the region and support the hypothesis that loss of appropriate habitat has led to smaller population sizes and a more fragmented distribution of this cedar glade endemic.

    Abstract Rifampin has very broad antimicrobial properties with in vitro activities against many bacteria, mycobacteria, higher bacteria, chlamydia, fungi, parasites, and viruses (Table 1). The clinical use of rifampin is more limited, in part because of the lack of in vivo human clinical studies demonstrating its efficacy. Investigators have valid concerns regarding the emergence of resistance of mycobacteria if widespread use of rifampin becomes common, although this has not been well documented. Because rifampin obtains therapeutic levels intracellularly and is distributed widely throughout the body, the antibiotic potentially could be used on a broader scale, but more studies will be needed to demonstrate its clinical utility.

    Abstract A force transducer with variable sensitivity and speed is described. Its moving element is a cantilever beam that projects vertically into a muscle bath. A brace constrains bending of the beam to a short, proximal "hinge." Rotation of the beam about the hinge is amplified 30-fold by an optical lever consisting of a laser diode beam reflected from a mirror on the cantilever to a photodiode pair. This design places the electrical components at a distance from the damp environment of the muscle bath. Large changes in sensitivity and speed can be obtained by substituting different cantilevers. Smaller changes can be made by varying the length of the hinge. A transducer with a 6-mm cantilever optimized for the study of single, skinned skeletal muscle fibers is described in detail. This device had a resonant frequency of 22 kHz and sensitivity such that the total root-mean-square noise in the circuit was more than 500-fold smaller than the expected maximum force. Variations of this device with orders of magnitude different sensitivities are also described.
