Sexual self-perceptions are important aspects of sexuality, which can undergo significant change during adolescence and early adulthood. The purpose of this study was to describe these changes among girls (N = 251; ages 16-25) over one year, and to examine associations of sexual self-perceptions (sexual subjectivity) with age, sexual behavior, and romantic status. Sexual body-esteem, perception...

3-Methylcholanthrene (3MC) is a ligand for arylhydrocarbon receptor (AhR), which binds dioxin. We examined the effects of 3MC on the proliferation and differentiation of osteoblasts using cultures of rat calvarial osteoblast-like cells (ROB cells) and mouse calvarial clonal preosteoblastic cells (MC3T3-E1 cells). Analysis by RT-PCR revealed that the mRNAs for AhR and AhR nuclear translocators w...

The pattern of ovulation in mammals is generally considered to be either spontaneous or induced by coitus. The present study aimed to assess the pattern of ovulation in the southern African spiny mice (Acomys spinosissimus). Females were divided into three treatments differing in the degree of contact with a male. Control females had no contact with males, separated females had only chemical, a...

In Drosophila, the piRNA cluster, flamenco, produces most of the piRNAs (PIWI-interacting RNAs) that silence transposable elements in the somatic follicle cells during oogenesis. These piRNAs are thought to be processed from a long single-stranded precursor transcript. Here, we demonstrate that flamenco transcription is initiated from an RNA polymerase II promoter containing an initiator motif ...

Hemocyanins are large multi-subunit copper proteins that transport oxygen in many arthropods and mollusts. The amino acid sequence of subunit a of Panulirus interruptus hemocyanin (657 residues) has been completed and fitted to the electron-density map (3.2 A resolution). Comparison of amino acid sequence data for several different hemocyanin subunits of arthropod species indicated that the gen...

Body structures of Drosophila develop through transient developmental units, termed parasegments, with boundaries lying between the adjacent expression domains of wingless and engrailed. Parasegments are transformed into the morphologically distinct segments that remain fixed. Segment borders are established adjacent and posterior to each engrailed domain. They are marked by single rows of stri...

The Hedgehog (HH) signaling proteins control cell fates and patterning during animal development. In Drosophila, HH protein induces the transcription of target genes encoding secondary signals such as DPP and WG proteins by opposing a repressor system. The repressors include Costal2, protein kinase A, and the HH receptor Patched. Like HH, the kinase Fused and the transcription factor Cubitus in...

In the first section of this exchange, Nancy Fraser restates the case for viewing modern social movements from the two perspectives, that of Recognition and that of Redistribution, that she put forward in Chapter 1 of Justice Interruptus. She has further developed her position, particularly with the introduction of the concept of participatory parity, and introduces a range of distinctions and ...

The present study is a report based on a small collection of the digenean fauna of marine fishes of Andaman. It consists of four species, Hysterolecithoides [ronti/atus (Manter, 1969), Hamacreadium interruptus Nagaty .. 1941, Mehracola ovocaudatum Srivastava, 1937 and Bivesicula australis Crowcroft, 1947. New facts and records about these species have been noted in addition to the important tax...
