Influence of Temperature and Photoperiod on Survival and Development of (Lepidoptera: Crambidae).

The Mexican rice borer, (Lepidoptera: Crambidae) is an economically important pest of sugarcane, rice, and corn in Louisiana, Texas, and Mexico. This pest is considered invasive in the US and is expanding its range northward. Due to its subtropical origin, 's northern distribution might be limited by cold tolerance.

Discovery of Potent Kappa Opioid Receptor Agonists Derived from Akuammicine.

Akuammicine (), an alkaloid isolated from , is an agonist of the kappa opioid receptor (κOR). To establish structure-activity relationships (SARs) for this structurally unique κOR ligand, a collection of semisynthetic derivatives was synthesized. Evaluating these derivatives for their ability to activate the κOR and mu opioid receptor (μOR) revealed key SAR trends and identified derivatives with enhanced κOR potency.

Exploring the Symptoms of and Insights Into Idiopathic Opsoclonus-Myoclonus-Ataxia Syndrome in Adults.

Opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare immunological central nervous system disorder that mostly affects children, and it is extremely uncommon in adults. It usually presents idiopathically, as a parainfectious condition, or as a paraneoplastic syndrome. We present a case of a patient who developed adult-onset opsoclonus-myoclonus-ataxia syndrome (OMAS) without any associated infectious or neoplastic disease, a condition that is considered very rare in Central America.

Parental Perspectives on Their Child's Body Image.

Poor body image is a prominent issue affecting youth. In this nationally representative online survey, we explored parents' concerns about their child's appearance, as well as their perceptions of their child's body image concerns and related behaviors and interactions with others. Among the 1653 respondents, weight was parents' most cited body image concern, while more parents perceived that their child was self-conscious about their weight than there were parents concerned about their child's weight.
