A Guide to Pediatric Antibiotic Allergy Testing: A Report from the United States Drug Allergy Registry.

Pediatric antibiotic labels are common, and unnecessary antibiotic avoidance is associated with negative personal and public health outcomes; as a result, there is an increasing emphasis on the importance of pediatric antibiotic allergy evaluations. Different testing strategies have been advised, including skin testing and challenge testing with varied doses and duration. Established consensus testing protocols are lacking.

Historical and Archaeogenomic Identification of High-Status Englishmen at Jamestown, Virginia.

Ancient DNA (aDNA) data are reported for two human skeletons buried within the chancel of the 1608-1616 church at the North American colonial settlement of Jamestown, Virginia. The men are suspected kinsmen of the colony's first Governor, Thomas West, 3 Baron De La Warr based on archaeological, osteological, and documentary evidence. Genomic analyses of these men, Sir Ferdinando Wenman and Captain William West, identify a shared mitochondrial haplogroup, H10e, inferring maternal relatedness.

Genetically encoded intrabody probes for labeling and manipulating AMPA-type glutamate receptors.

Tools for visualizing and manipulating protein dynamics in living cells are critical for understanding cellular function. Here we leverage recently available monoclonal antibody sequences to generate a set of affinity tags for labeling and manipulating AMPA-type glutamate receptors (AMPARs), which mediate nearly all excitatory neurotransmission in the central nervous system. These antibodies can be produced from heterologous cells for exogenous labeling applications or directly expressed in living neurons as intrabodies, where they bind their epitopes in the endoplasmic reticulum and co-traffic to the cell surface for visualization with cell impermeant fluorescent dyes.

Combination of Haloperidol With UNC9994, β-arrestin-Biased Analog of Aripiprazole, Ameliorates Schizophrenia-Related Phenotypes Induced by NMDAR Deficit in Mice.

Background: Glutamatergic system dysfunction contributes to a full spectrum of schizophrenia-like symptoms, including the cognitive and negative symptoms that are resistant to treatment with antipsychotic drugs (APDs). Aripiprazole, an atypical APD, acts as a dopamine partial agonist, and its combination with haloperidol (a typical APD) has been suggested as a potential strategy to improve schizophrenia. Recently, an analog of aripiprazole, UNC9994, was developed.
