DEP-1 is a brain insulin receptor phosphatase that prevents the simultaneous activation of counteracting metabolic pathways.

A healthy metabolism relies on precise regulation of anabolic and catabolic pathways. While insulin deficiency impairs anabolism, insulin resistance in obesity causes metabolic dysfunction, especially via altered brain insulin receptor (IR) activity. Density-enhanced phosphatase 1 (DEP-1) negatively modulates the IR in peripheral tissues.

[Hybrid diagnosis-related groups-The challenge].

The introduction of hybrid diagnosis-related groups (DRG) presents new challenges for healthcare providers and health insurances. The same applied in 2023 to the institute designated by the Federal Ministry of Health (BMG) to extract medical procedures and calculate remuneration levels for the first hybrid DRGs. A responsible calculation methodology and a realistic data basis are required as the result of the calculation can lead to controversy, even to a splitting among specialist groups and constructs.

Moving through Toronto's PATH: Assembling private urban governance.

This paper explores Toronto's urban PATH, a 30 km network of underground pedestrian tunnels and elevated walkways that connect shopping areas, residential towers, mass transit and downtown destinations. Both as a case and heuristic, this paper situates Toronto's PATH as an assemblage of private urban governance forms, exploring emergent and evolving constellations of power and responsibility for governing city space that defy easy distinctions of 'public' or 'private'. As an urban assemblage, the PATH comprises potential and actual entities and associations, and is an accumulation of encounters.

Acute elevated dietary fat alone is not sufficient to decrease AgRP projections in the paraventricular nucleus of the hypothalamus in mice.

Within the brain, the connections between neurons are constantly changing in response to environmental stimuli. A prime environmental regulator of neuronal activity is diet, and previous work has highlighted changes in hypothalamic connections in response to diets high in dietary fat and elevated sucrose. We sought to determine if the change in hypothalamic neuronal connections was driven primarily by an elevation in dietary fat alone.

Fasting-induced activity changes in MC3R neurons of the paraventricular nucleus of the thalamus.

The brain controls energy homeostasis by regulating food intake through signaling within the melanocortin system. Whilst we understand the role of the hypothalamus within this system, how extra-hypothalamic brain regions are involved in controlling energy balance remains unclear. Here we show that the melanocortin 3 receptor (MC3R) is expressed in the paraventricular nucleus of the thalamus (PVT).
