Unlabelled: Motivated behaviors are regulated by distributed forebrain networks. Traditional approaches have often focused on individual brain regions and connections that do not capture the topographic organization of forebrain connectivity. We performed co-injections of anterograde and retrograde tract tracers in rats to provide novel high-spatial resolution evidence of topographic connections that elaborate a previously identified closed-loop forebrain circuit implicated in affective and motivational processes.

Ivermectin (IVM) is one of the most widely used antiparasitic drugs worldwide and has become the drug of choice for anthelmintic and tick treatment in beef cattle production. Drugs used in production animals requires a withdrawal period after treatment to avoid residual concentrations above the defined maximun residue level (MRL). The aims of this study were to quantify the residue level of IVM in different muscles of cattle at several different time periods following 1% or 3.

Objectives: Infantile hemangioma (IH) is a benign vascular tumor that occurs in 5% of infants, predominantly in female and preterm neonates. Propranolol is the mainstay of treatment for IH. Given the short half-life of propranolol regarding β-adrenergic receptor inhibition as well as its side effects, propranolol is administered to infants 2-3 times daily with 1 mg/kg/dose.

Background: There is much concern that opioids administered as intravenous (iv) bolus for pain relief may inadvertently increase their risk for abuse. However, there is insufficient data to support this. The authors compared the abuse liability potential, analgesic efficacy, and adverse effect profile of fast (iv push) versus slow (iv piggyback) administration of iv hydromorphone among hospitalized patients requiring iv opioids for pain.

Numerous unregulated organic compounds (UOCs) including pharmaceuticals, opioids, and personal care products (PCPs) end up in wastewater. UOC presence in biosolids (a wastewater treatment byproduct), which are applied to soil for different reasons raises environmental and health risk concerns. In this study, two multi-class extraction methods were developed and validated to target 111 UOCs from 8 different major families simultaneously in biosolids and biosolids-impacted soil.
