Activating direct olfactory (glutamatergic) inputs to supraoptic nucleus (SON) neurons increases interneuronal coupling in slices from lactating but from not virgin or male rats. Studied here were influences on coupling of another monosynaptic input to SON, the histaminergic tuberomammillary nucleus (TM) projection, activation of which selectively excites phasically firing (putative vasopressin...

The ground field k is algebraically closed and of characteristic zero. Let g be a reductive algebraic Lie algebra over k and σ an involutory automorphism of g. Then g = g0 ⊕ g1 is the direct sum of σ-eigenspaces. Here g0 is a reductive subalgebra and g1 is a g0-module. Let G be the adjoint group of g and G0 ⊂ G a connected subgroup with LieG0 = g0. The commuting variety of (g, g0) is the follow...

The natural environment is in a state of constant flux and living organisms are perpetually challenged to adapt to these changes. Yet the mechanisms of adaptation, which lead to the development of new characteristics or behaviours, have troubled philosophers and scientists since the days of ancient Greece. In fact, it was not until 1859, when Charles Darwin (1809– 1882) published The Origin of ...

Background Familial amyloid polyneuropathy (FAP ATTRV30M) is an autosomal dominant systemic amyloidosis, due to a point mutation in the transthyretin (TTR) gene (chr18q12.1). The most frequent one, V30M is associated with several clusters. Among Portuguese families, FAP shows a wide variation in in age-at-onset (AO) [19-82 yrs] and this variability is also apparent between generations. Also, si...

Intergenerational Income Persistency in Urban China Intergenerational income elasticities are estimated using samples for urban China (covering many cities) for the years 1995 and 2002 and compared with results from other studies. We find that the income relation between the pairs: sons and fathers, sons and mothers and daughters and mothers, are in 2002 all similar in magnitude. In contrast th...

This paper presents a task-based user study carried out to investigate how explicit roles assigned to group members affected collaborative information seeking behaviour during a travel planning task. 24 pairs participated our study where half of them were given a specific instruction to divide the roles into a searcher and writer, while others were given no such instruction. The evaluation look...

The Y chromosome is one of the smallest human chromosomes with an average size of 60 million base pairs (Mb). Between X and Y chromosomes, exchange is limited to small pseudoautosomal regions (PAR) of the X-Y pair (see Figure 1). During male meiosis, recombination only takes place at the most distal short arm (PAR 1) and at the tip of the Y chromosome long arm (PAR 2). For most of its length (t...
