Adrenergic modulation of melanocortin pathway by hunger signals

Yılmaz, Bayram | Yavuz, Yavuz

Norepinephrine (NE) is a well-known appetite regulator, and the nor/adrenergic system is targeted by several anti-obesity drugs. To better understand the circuitry underlying adrenergic appetite control, here we investigated the paraventricular hypothalamic nucleus (PVN), a key brain region that integrates energy signals and receives dense nor/adrenergic input, using a mouse model. We found that PVN NE level increases with signals of energy deficit and decreases with food access. This pattern is recapitulated by the innervating catecholaminergic axon terminals originating from NTSTH-neurons. O ...Daha fazlası

Global art market and art economy after 2000 and Turkey: The evolution, resilience, and global prominence of the Turkish art market

Üler Kaprol, Tuğçe

The term "market" has deep historical roots, evolving from a physical space for trade to an abstract concept symbolizing the exchange of goods and services. In the sociology of art, Pierre Bourdieu has shaped a distinctive path of research, emphasizing taste judgments, cultural power, and cultural capital as tools for social dominance. This foundation aids in understanding the intricacies of the art market. Over time, art has transformed into an alternative investment for corporate entities, wealth managers, banks, and individuals, driven by economic shifts since the 1980s. The 1980s saw the p ...Daha fazlası
