5-HT Receptors in the BNST Modulate Contextual Fear Conditioning Without Affecting Acute Early Life Stress-Enhanced Fear Learning in Adult Rats.

Background/objectives: Rodents provide a useful translational model of fear- and anxiety-related behaviors. Previously stressed animals exhibit physiological and behavioral stress responses that parallel those observed in anxious humans. Patients diagnosed with post-traumatic stress disorder (PTSD) present with a spectrum of debilitating anxiety symptoms that result from exposure to one or more traumatic events, with individuals exposed to early adverse experiences and women having increased vulnerability for diagnoses; however, the mechanisms of this increased vulnerability remain unknown.

Management of severe traumatic brain injury in a rivaroxaban overdose: illustrative case.

Background: The management of rivaroxaban overdose in severe traumatic brain injury (sTBI) is undocumented. Reversal with andexanet alfa (AA) and prothrombin complex concentrates (PCCs) in cases of supratherapeutic doses remains unproven. Management is further complicated by the absence of real-time serum rivaroxaban concentration assays and drug-specific coagulation assays.

Disentangling the effect of growth from development in size-related trait scaling relationships.

In plant ecology, the terms growth and development are often used interchangeably. Yet these constitute two distinct processes. Plant architectural traits (e.

Bark water uptake through lenticels increases stem hydration and contributes to stem swelling.

Foliar water uptake can recharge water storage tissue and enable greater hydration than through access to soil water alone; however, few studies have explored the role of the bark in facilitating water uptake. We investigated pathways and dynamics of bark water uptake (BWU) in stems of the mangrove Avicennia marina. We provide novel evidence that specific entry points control dynamics of water uptake through the outer bark surface.
