‘‘An old quarrel between us that will never be at an end": Middleton’s Women Beware Women and Late Jacobean Religious Politics

In this article, I examine Thomas Middleton's Women Beware Women as a response to the particular religio-political context in the years surrounding 1621. The onset of the Thirty Years War in 1618 and the subsequent humiliation of James' son-in-law Frederick, Elector of Palatine, the vexed question of a possible Catholic marriage for Charles, Prince of Wales, the ever present difficulty of Anglo-Catholic relations, particularly with Spain, as well as growing religious factionalism within the Church of England between Calvinists and Arminians: all contributed towards a culturally febrile atmosphere, one to which, as I will argue, Middleton was well placed to respond. Given Middleton's Calvinistic beliefs, I suggest that Women Beware Women offers an acerbic examination of contemporary debates concerning human will, especially women's will, as well as promoting a sceptically apocalyptic anti-Catholic agenda throughout. I also examine the religious language and imagery used to construct Bianca as the whore of Babylon, and argue that her emergence and fall offer a political commentary on the precarious position of the English Church around 1621.

Antibody Targeting of Cathepsin S Inhibits Angiogenesis and Synergistically Enhances Anti-VEGF

BACKGROUND: Angiogenesis is a key hallmark of tumourigenesis and its inhibition is a proven strategy for the development of novel anti-cancer therapeutics. An important aspect of early angiogenesis is the co-ordinated migration and invasion of endothelial cells through the hypoxic tumour tissue. Cathepsin S has been shown to play an important role in angiogenesis as has vascular endothelial growth factor (VEGF). We sought to assess the anti-angiogenic effect of Fsn0503, a novel cathepsin S inhibitory antibody, when combined with anti-VEGF on vascular development.

METHODOLOGY/PRINCIPAL FINDINGS: Cathepsin S expression and secretion from endothelial cells was characterised using RT-PCR and western blotting. We further show that cathepsin S promotes pericellular hydrolysis of extracellular matrix components in the tumour microenvironment and facilitates endothelial invasion. The cathepsin S inhibitory antibody, Fsn0503, blocks extracellular proteolysis, inhibiting endothelial invasion and tube formation in cell-based assays. The anti-angiogenic effects of Fsn0503 were also shown in vivo where it significantly retarded the development of vasculature in human xenograft models. Furthermore, when Fsn0503 was combined with an anti-VEGF antibody, a synergistic inhibition of microvascular development was observed.

CONCLUSIONS/SIGNIFICANCE: Taken together, this data demonstrates that the antibody-mediated targeting of cathepsin S represents a novel method of inhibiting angiogenesis. Furthermore, when used in combination with anti-VEGF therapies, Fsn0503 has the potential to significantly enhance current treatments of tumour neovascularisation and may also be of use in the treatment of other conditions associated with inappropriate angiogenesis.

James Croll, metaphysical geologist

James Croll (1821–90) occupies a prominent position in the history of physical geology, and his pioneering work on the causes of long-term climate change has been widely discussed. During his life he benefited from the patronage of leading men of science; his participation in scientific debates was widely acknowledged, not least through his election as a Fellow of the Royal Society in 1876. For all that, the intellectual contribution that Croll himself considered to be of most significance—his articles and two books on metaphysics—has attracted very little attention. In addressing this neglect, it is argued here that Croll's interest in metaphysics, grounded in his commitment to a Calvinist form of Christianity, was central to his life and thought. Examining together Croll's geophysical and metaphysical writings offers a different and fruitful way of understanding his scientific career and points to the wider significance of metaphysics in late-Victorian scientific culture.

Detection of unwanted residues of ivermectin in bovine milk by dissociation-enhanced lanthanide fluoroimmunoassay

Avermectins are frequently used to control parasitic infestations in many animal species. Previous studies have shown the long-term persistence of unwanted residues of these drugs in animal tissues and fluids. An immunoassay screening test for the detection acid quantification of ivermectin residues in bovine milk has been developed. After an extensive extraction procedure, milk samples were applied to a competitive dissociation-enhanced lanthanide fluoroimmunoassay using a monoclonal antibody against an ivermectin-transferrin conjugate, The monoclonal antibody, raised in Balb C mice, showed cross-reactivity with eprinomectin (92%), abamectin (82%) and doramectin (16%). The limit of detection of the assay (mean + 3 SD), calculated from the analysis of 17 known negative samples, was calculated as 4.6 ng/mL. Intra- and inter-assay RSDs were determined as 11.6% and 15.8%, respectively, using a negative bovine milk sample fortified with 25 ng/mL ivermectin. Six Friesian milking cows were treated with ivermectin, three with a pour-on formulation of the drug and three with an injectable solution at the manufacturer's recommended dose rate. An initial mean peak in ivermectin residue concentration was detected at day 4 (mean level = 47.5 ng/mL) and day 5 post-treatment (mean level = 26.4 ng/mL) with the injectable form and pour-on treatment, respectively. A second peak in residue concentration was observed using the DELFIA(R) procedure 28 days post-treatment in both treatment groups (23.1 ng/mL injectable and 51.9 ng/mL pour-on). These second peaks were not confirmed by HPLC and must at this Lime be considered to be false-positive results. By day 35 after treatment the mean ivermectin residue concentration of both groups fell below the limit of detection of the assay. Copyright (C) 2000 John Wiley & Sons, Ltd.

Glacial Survival of Boreal Trees in Northern Scandinavia

It is commonly believed that trees were absent in Scandinavia during the last glaciation and first recolonized the Scandinavian Peninsula with the retreat of its ice sheet some 9000 years ago. Here, we show the presence of a rare mitochondrial DNA haplotype of spruce that appears unique to Scandinavia and with its highest frequency to the west—an area believed to sustain ice-free refugia during most of the last ice age. We further show the survival of DNA from this haplotype in lake sediments and pollen of Trøndelag in central Norway dating back ~10,300 years and chloroplast DNA of pine and spruce in lake sediments adjacent to the ice-free Andøya refugium in northwestern Norway as early as ~22,000 and 17,700 years ago, respectively. Our findings imply that conifer trees survived in ice-free refugia of Scandinavia during the last glaciation, challenging current views on survival and spread of trees as a response to climate changes.
