The larva of the ixodid tick Dermacentor parumapertus Neumann, chiefly a parasite of hares and rabbits, is redescribed using scanning electron micrographs of seven specimens derived from two engorged females collected from two black-tailed jackrabbits, Lepus californicus, at the Black Gap Wildlife Management Area, Brewster County, southwestern Texas. The use of chaetotaxy for separating the genera of Ixodidae is discussed, and a morphological key is provided for separating the larvae of D. parumapertus from those of five other Dermacentor species with partly sympatric geographic ranges.

The article discusses drama criticism of "The Rehearsal" by George Villiers, "Othello" by William Shakespeare, and "Gammer Gurton's Needle" by William Stevenson. It mentions that Senators are a silent auditory as the drama of father and eloping lovers plays out in front of them. It also mentions that "Gammer Gurton's Needle" King adds to its performance history within Britain.

An early modern play-title may not be authorial and may be one of several given to the same piece. This essay takes the play usually known simply as 'Othello' as a case-study by collecting and examining records of the play in performance and print, before the closing of the theatres, during the interregnum and in the quarter-century following the resumption of playing in 1660. For almost all of these seventy-five years, the use of the character Othello's name to title the play is predominantly a print phenomenon or a usage by writers encountering the play in print. Performance records begin in Shakespeare's lifetime, antedating printed forms. They consistently record a different title, emphasizing the character's race and location. The disparity between print and performance titles invites a reconsideration of seventeenth-century records of performance and audience experience of the play, offering Pepys's experience of the play as a sample.

The cuticular sensory receptors that are found on the apex of the labium of hemipterans play an important role in their feeding behavior. In this study we describe the ultrastructure, number, and distribution of sensilla on the labium apex of the chinch bug, Blissus leucopterus leucopterus. Each apical field of sensilla on the labium contains 11 uniporous peg sensilla and one sensillum chaeticum. The uniporous peg sensilla are innervated by 4–5 bipolar neurons that send dendrites in the lumen of each peg. Three neurons are associated with each sensillum chaeticum, two neurons have dendrites in the lumen of the sensillum, and the third dendrite ends in a tubular body at the base of the sensillum. Behavioral tests that involve chemical blockage of the sensory receptors show the importance of the labial sensilla in feeding behavior. Both morphological and behavioral evidence indicate that the labial sensilla have a chemosensitive function. [ABSTRACT FROM AUTHOR]

In 2004, we determined baseline data on fungal-community assemblages from Solenopsis invicta (Red Imported Fire Ant) mounds in 3 counties (Hinds, Leake, and Madison) within the Natchez Trace Parkway, MS. We assayed mound soil, plant debris within the mounds, and ants obtained from mounds on 3 sampling dates (March, July, and November). We processed samples based on standard microbiological protocols, and used traditional morphological and molecular techniques to identify fungal taxa. We documented a total of 1445 isolates consisting of 50 fungal taxa and calculated a diversity index value (H′) of 3.11 across all substrates, which was indicative of a variable fungal community within the mounds. The taxa with the highest percent isolation frequencies included Hypocrea lixii (12.8%), Fusarium sp. 1 (12.3%), Fusarium equiseti (7.9%), Purpureocillium lilacinum (= Paecilomyces lilacinus) (6.5%), Fusarium oxysporum 2 (5.8%), and Mortierella alpina (5.4%). We isolated 2 common parasitic (entomopathogenic) fungi, Purpureocillium lilacinum and Metarhizium anisopliae var. anisopliae (9.4%), from mound soil, plant debris, and ant external tissues. Hypocrea lixii, the teleomorphic reproductive stage of Trichoderma harzianum, is noted as a natural biological control of some soil-borne microbes, possibly limiting important natural entomopathogenic activity within the mounds. Species richness and diversity values from mound soils across locations were significantly greater ( P ≤ 0.05) than those from the plant debris and ant body-tissue substrates. Species richness values between locations were similar. Species richness of samples collected in November (47) was significantly greater ( P ≤ 0.05) than that of the March (41) and July (39) samples. Community coefficient values ranged from 0.79 to 0.87 between substrates, 0.85 to 0.91 between locations, and 0.85 to 0.86 between sampling dates, indicating that taxa were similar.

To date, there is no objective or reliable means of assessing the severity of degenerative joint disease (DJD) and need for joint replacement surgery. Hence, it is difficult to know when an individual with DJD has reached a point where total arthroplasty is indicated. The purpose of the present study is to determine whether serum levels of Alpha-2 HS-glycoprotein (AHSG) as well as bone morphogenetic proteins (BMP-2, 4, 7) can be used to predict the presence of severe DJD of the hip and/or temporomandibular joint (TMJ) (specifically: joints that require replacement). A total of 30 patients scheduled for arthroplasty (diseased) (15 HIP, 15 TMJ) and 120 age-matched controls (healthy/non-diseased) were included. Blood samples were collected from all patients ≥8 weeks after the last arthroplasty. Concentrations of serum analytes were measured using enzyme-linked immunosorbent assays, and these were compared between the Diseased and Healthy groups, utilizing the Mann-Whitney U-test. Patients with disease had significantly higher levels of BMP-2 and BMP-4 and lower levels of AHSG in serum compared to non-diseased humans ( p < 0.01). Higher levels of BMP-2, 4 and reduced levels of AHSG appear to characterize patients who have DJD that is severe enough to require total joint replacement. Perhaps measurements of these proteins can be used to make objective decisions regarding the need for total arthroplasty as opposed to the current subjective approaches. © 2012 Orthopaedic Research Society.
