How does competition affect bank systemic risk
Using bank level measures of competition and co-dependence, we show a robust negative relationship between bank competition and systemic risk. Whereas much of the extant literature has focused on theExpand

Dietary deprivation extends lifespan in Caenorhabditis elegans
Dietary restriction (DR) is well known as a nongenetic intervention that robustly extends lifespan in a variety of species; however, its underlying mechanisms remain unclear. We have found inExpand

A Silurian placoderm with osteichthyan-like marginal jaw bones
The gnathostome (jawed vertebrate) crown group comprises two extant clades with contrasting character complements. Notably, Chondrichthyes (cartilaginous fish) lack the large dermal bones thatExpand

B cells promote inflammation in obesity and type 2 diabetes through regulation of T-cell function and an inflammatory cytokine profile
Patients with type 2 diabetes (T2D) have disease-associated changes in B-cell function, but the role these changes play in disease pathogenesis is not well established. Data herein show B cells fromExpand

The oldest articulated osteichthyan reveals mosaic gnathostome characters
The evolutionary history of osteichthyans (bony fishes plus tetrapods) extends back to the Ludlow epoch of the Silurian period. However, these Silurian forms have been documented exclusively byExpand

A primitive fossil fish sheds light on the origin of bony fishes
Living gnathostomes (jawed vertebrates) include chondrichthyans (sharks, rays and chimaeras) and osteichthyans or bony fishes. Living osteichthyans are divided into two lineages, namelyExpand

A primitive fish provides key characters bearing on deep osteichthyan phylogeny
Osteichthyans, or bony vertebrates, include actinopterygians (teleosts and their relatives) and sarcopterygians (coelacanths, lungfishes and tetrapods). Despite features found in basalExpand

Severe growth retardation and early lethality in mice lacking the nuclear localization sequence and C-terminus of PTH-related protein
Parathyroid hormone (PTH) plays a central role in the regulation of serum calcium and phosphorus homeostasis, while parathyroid hormone-related protein (PTHrP) has important developmental roles. BothExpand

Fossil jawless fish from China foreshadows early jawed vertebrate anatomy
Most living vertebrates are jawed vertebrates (gnathostomes), and the living jawless vertebrates (cyclostomes), hagfishes and lampreys, provide scarce information about the profound reorganization ofExpand

Calorie restriction mimetics: an emerging research field
When considering all possible aging interventions evaluated to date, it is clear that calorie restriction (CR) remains the most robust. Studies in numerous species have demonstrated that reduction ofExpand
