Domestic violence, coercive control and mental health in a pandemic: disenthralling the ecology of the domestic

ABSTRACTDomestic and family violence is a social and public health issue typically positioned in policy frameworks as a consequence of gendered social and economic structures. In this paper, we deploy an approach that draws on Hörl's neo-ecological thinking to propose that the home, as a site of domestic violence, can be usefully framed as an ecology of the domestic, a posthumanist hybrid matrix of bodies, spaces and objects in which various practices enact the smooth running of the domestic together with practices of domestic and family violence, including coercive control. Our interest is in coercive control and in the impact that the COVID-19 pandemic had on practices which enact this aspect of domestic violence. Our exploration of the practices that enact coercive control draws on the work of Law and others. We examine how practices, which are not compatible, or that do not cohere, are able to coexist in a domestic ecology and what occurs when there is a disruption as occurred with the pandemic.

Recent advances in mono and binuclear gold photoredox catalysis

In this minireview, recent developments in the field of photoredox catalysis and the applications of mono and binuclear Au(i) complexes in organic transformations are discussed.

The photochemical alkylation and reduction of heteroarenes

The functionalization of heteroarenes has been integral to the structural diversification of medicinally active molecules such as quinolines, pyridines, and phenanthridines. Electron-deficient heteroarenes are electronically compatible to react with relatively nucleophilic free radicals such as hydroxyalkyl. However, the radical functionalization of such heteroarenes has been marked by the use of transition-metal catalyzed processes that require initiators and stoichiometric oxidants. Herein, we describe the photochemical alkylation of quinolines, pyridines and phenanthridines, where through direct excitation of the protonated heterocycle, alcohols and ethers, such as methanol and THF, can serve as alkylating agents. We also report the discovery of a photochemical reduction of these heteroarenes using only iPrOH and HCl. Mechanistic studies to elucidate the underlying mechanism of these transformations, and preliminary results on catalytic methylations are also reported.

Photoredox meets gold Lewis acid catalysis in the alkylative semipinacol rearrangement: a photocatalyst with a dark side

The alkylative semipinacol rearrangement of a variety of TMS protected α-styrenyl substituted cyclic alcohols with unactivated bromoalkanes that merge photoredox and Au(i)/Au(iii) catalysis has been achieved.

Direct alkylation of heteroarenes with unactivated bromoalkanes using photoredox gold catalysis

Although visible light photoredox catalysis has emerged as a powerful tool for the construction of C-C bonds, common catalysts and/or their photoexcited states suffer from low redox potentials, limiting their applicability to alkyl radical generation from substrates with activated carbon-halogen bonds. Radicals derived from these activated compounds, being highly electrophilic or stabilized, do not undergo efficient addition to heteroarenes. Herein we describe the photocatalytic generation of nucleophilic alkyl radicals from unactivated bromoalkanes as part of a universal and efficient cross-coupling strategy for the direct alkylation of heteroarenes using a dimeric gold(i) photoredox catalyst, [Au2(bis(diphenylphosphino)methane)2]Cl2. The method proves to be efficient for alkylation of arenes under mild conditions in the absence of directing groups.

Polynuclear gold(i) complexes in photoredox catalysis: understanding their reactivity through characterization and kinetic analysis

The light mediated reduction of unactivated carbon–halogen bonds using polynuclear gold(i) complexes provides a mild and temporally controlled route to the generation of C–H, and C–C bonds.

Unilateral renal agenesis associated with congenital bilateral absence of the vas deferens: phenotypic findings and genetic considerations

An association between congenital bilateral absence of the vas deferens (CBAVD), normal renal anatomy and cystic fibrosis (CF) gene mutations is well established (CF/CBAVD). We postulate that unilateral renal agenesis (URA) and CBAVD (URA/CBAVD) may have a non-CF mutation-mediated genetic basis that leads to abnormal development of the entire mesonephric duct at a very early stage in embryo development (< or =7 weeks). The physical, laboratory and radiographic findings of men with URA/CBAVD (n = 17) and CF/CBAVD (n = 97) were compared; the fertilization and pregnancy rates in the URA/CBAVD population calculated, and the incidence of renal agenesis in immediate family members and offspring of men with URA/CBAVD analysed. No statistical differences could be identified within any of the above comparisons. The fertilization rate for the URA/CBAVD group was 58.2 +/- 26.3%. Eight infants and two fetuses had normal renal anatomy, while one terminated male fetus had bilateral renal and vasal agenesis. Thirty first-order relatives had normal renal units. Anatomical expression of the reproductive ductal derivatives in men with URA/CBAVD and CF/CBAVD was similar, but the phenotypic outcome of the renal portion of the mesonephric duct was different. The potential for transmission of this fatal anomaly reinforces the need for prenatal ultrasounds with all pregnancies involving URA/CBAVD men.

Introducing annamarie jagose

SUMMARY Annamarie Jagose's fiction can be loosely divided into the early short stories and the later novels. The stories are generally feminist and lesbian in content and characters, and contain many traditional story elements. The novels, In Translation and Lulu,are more complex works. In these texts, Jagose is interested in "queering" identity, both heterosexual and homosexual, and in questioning the effectiveness of these traditional taxonomies. Both the stories and novels feature an exquisite control of language, a wry humour, and a deft understanding of human relationships.

Furazolidone-induced injury in the isolated perfused chicken heart

The Langendorff isolated heart preparation was adapted to determine the effect of furazolidone (0.5 and 2 micrograms/ml of perfusate) on hearts of 3-week-old broiler chickens. Following 115 minutes of perfusion, both concentrations of furazolidone caused approximately a two-fold increase in myocardial vascular resistance and a six-fold increase in lactate dehydrogenase release into the effluent fluid, compared with a control perfused group of isolated hearts (P less than 0.01). Ultrastructural alteration differences were not found between the drug-treated and control groups. It was concluded that: (i) furazolidone, at concentrations only moderately above therapeutic plasma concentrations, caused detrimental changes in myocardial vascular resistance and lactate dehydrogenase release and (ii) the isolated chicken heart preparation is an example of a cost-effective, reliable laboratory tool for screening potential cardiotoxins.
