Control of the koala (Phascolarctos cinereus) anterior pituitary-godadal axis with analogues of GnRH

The aim of the present study was to determine whether analogues of gonadotrophin-releasing hormone (GnRH) could be used to both induce an acute testosterone response and suppress anterior pituitary function in male koalas, and induce a luteal phase in female koalas. Experiment 1 characterised the steroidogenic response of male koalas to administration of 30 μg (4.3 μg kg–1) natural-sequence GnRH. Intra-muscular injection of natural-sequence GnRH induced the release of LH and testosterone with peak concentrations at 30 min (3.7 ± 1.9 ng mL–1) and 2 h (5.4 ± 0.5 ng mL–1), respectively. In Experiment 2, a single injection of the GnRH antagonist acyline (100 μg (14.3 μg kg–1) or 500 μg (71.4 μg kg–1)) did not influence the testosterone response to subsequent injections of natural-sequence GnRH. In Experiment 3, 4 μg (~0.67 μg kg–1) of the GnRH agonist buserelin induced a luteal phase in five female koalas based on a LH surge, secretion of progestogen, and a normal-length oestrous cycle. The findings have shown that (1) natural-sequence GnRH can be used to test gonadotroph cell function and determine the testosterone-secreting capacity of male koalas, (2) the GnRH antagonist, acyline, at the dose rates used, does not suppress the pituitary-testis axis in male koalas, and (3) the GnRH agonist, buserelin, induces a normal luteal phase in female koalas

Gênero e insegurança no trabalho no Reino Unido Gender and employment insecurity in the UK

O objetivo deste artigo é explorar a dimensão de gênero da insegurança do emprego no Reino Unido, focalizando, para tanto, as recentes tendências do trabalho temporário, que incluem o de prazo fixo, o sazonal, o sem vínculo empregatício, o contratado através de agência, o ocasional e outros tipos de trabalho temporário. Essas formas de trabalho são, inequivocamente, inseguras, sejam elas livremente escolhidas ou não. A primeira seção do artigo trata das pressões e resistências que têm, cumulativamente, levado à atual participação de mulheres no trabalho remunerado. Examinam-se, em seguida, as recentes tendências nos padrões de emprego no Reino Unido, com especial referência às diferenças entre mulheres em idade de trabalho, bem como à incidência e distribuição do trabalho de meio período. As tendências recentes e as diferenças de gênero no trabalho temporário são, assim, consideradas à luz desse contexto mais amplo. Finalmente, esses achados são confrontados com os argumentos no sentido de que o emprego atípico fornece oportunidades para um aumento da participação de mulheres na força de trabalho e para uma conciliação prática entre o emprego e os papéis e relacionamentos familiares.<br>The objective of this article is to explore how far employment insecurity is gendered in the UK, focusing on recent trends in temporary employment, covering fixed term, seasonal, agency, casual and other temporary work. The first section of this paper considers the pressures and resistances that have cumulatively led to women's current participation in paid work. This is followed by an examination of recent trends in UK employment patterns, with particular reference to differences within the female population of working age and the incidence and distribution of part-time employment. Recent trends and gender differences in temporary employment are then considered against this broader background. Finally, this evidence is considered in relation to arguments that atypical employment provides opportunities for women's increased labour force participation and the practical reconciliation of employment and family roles and relationships
