ETHNOPHARMACOLOGICAL RELEVANCE: Essential oils obtained from resins of Boswellia carteri Birdw. and Commiphora myrrha (Nees) Engl., commonly known as frankincense and true myrrh respectively, have been used extensively since 2800 B.C. for the treatment of skin sores, wounds, teeth, inflammation, and urinary tract diseases in traditional medicine; for preparation of mummification balms and unguents; and also as incense and perfumes. Since ancient times, burning of frankincense and myrrh in places of worship for spiritual purposes and contemplation (a ubiquitous practice across various religions) had hygienic functions, to refine the smell and reduce contagion by purifying the indoor air...

Adolescence is a period during which a number of critical neuromaturation processes occur and the vulnerability for developing nicotine dependence is extremely high. Thus, early-onset (EO; age < 16 years old), relative to late-onset (LO; age ≥ 16 years old), tobacco smoking may be uniquely deleterious for developmentally immature systems that regulate neural signaling reactivity. This study investigated how age of tobacco smoking onset affects neurophysiological measures of smoking cue reactivity and reported craving in adult smokers...

BACKGROUND: Early-onset sepsis (EOS) is a potentially fatal condition that affects about 0.3-0.8/1,000 infants born at ≥35 weeks' gestation in developed countries. Current EOS management algorithms result in 8-15% of infants receiving antibiotics for suspected sepsis. The Neonatal Sepsis Calculator provides evidence-based estimates of individual sepsis risk, but data on its clinical application is limited. OBJECTIVES: To evaluate the feasibility, safety, and effect on the newborn infants that were investigated and that received antibiotic treatment for suspected EOS following the introduction of the Neonatal Sepsis Calculator...

In the phytopathogenic basidiomycete Ustilago maydis, the Num1 protein has a pivotal function in hyphal morphogenesis. Num1 functions as a core component of the spliceosome-associated Prp19/CDC5 complex (NTC). The interaction of Num1 with the kinesin motor Kin1 suggests a connection between a component of the splicing machinery and cytoplasmic trafficking processes. Previously it was shown that Num1 localizes predominantly in the nucleus; however, due to the diffraction-limited spatial resolution of conventional optical microscopy, it was not possible to attribute the localization to specific structures within the cytoplasm...

Group B streptococci are common causative agents of early-onset neonatal sepsis (EOS). Pharmacokinetic (PK) data for penicillin G have been described for extremely preterm neonates but poorly for late-preterm and term neonates. Thus, evidence-based dosing recommendations are lacking. We described PK of penicillin G in neonates with gestational age (GA) ≥32 weeks and postnatal age <72 h. Penicillin G was administered intravenously at a dose of 25,000 or 50,000 IU/kg/q12h. At steady state, PK blood samples were collected prior to and at 5 min, 1 h, 3 h, 8 h, 12 h after injection...
