This study demonstrates the independent longitudinal effect of maternal anxiety on major markers of fetal-neonatal growth outcomes and trajectories, simultaneously considering the effect of maternal depression and anxiety.
The compounds responsible for the so‐called ‘cork taint’ include, among others, some microbial metabolites which can be produced by the microbial population colonizing the unprocessed cork and stoppers. This study was intended to obtain information on the mycobiota associated with Portuguese cork throughout the manufacturing process of stoppers. Samples of barks and stoppers of both ‘normal’ and ‘green’ cork were examined. Moulds were isolated from ‘normal’ and ‘green’ cork throughout the entire cork stopper manufacturing process. Yeasts were rarely detected in the corks. Fungal contamination was not detected in finished stoppers from the company under study.
Dicyphine mirids are one of the most important groups of predators on tomato. In the Mediterranean region, several species in the genera Dicyphus, Macrolophus, and Nesidiocoris (Hemiptera: Miridae, Bryocorinae, Dicyphini) colonize protected horticultural crops. In Portugal, Nesidiocoris tenuis (Reuter) is increasingly abundant in the mirid species complex of tomato crops and appears to be displacing the native Dicyphus cerastii Wagner. In order to know whether intraguild predation (IGP) can explain the decreasing abundance of D. cerastii, we evaluated predatory interactions between adult females and first instars of D. cerastii vs. N. tenuis but also D. cerastii vs. Macrolophus pygmaeus (Rambur), as this species is also naturally present in horticultural crops in Portugal. Cannibalistic interactions were also tested for the same three species. All experiments were performed under laboratory conditions, in Petri dish arenas, in the presence or absence of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs as alternative prey. Predation on both heterospecific and conspecific nymphs occurred only in the absence of alternative food. Intraguild predation was mutual and symmetrical between D. cerastii and M. pygmaeus. However, IGP was asymmetrical between D. cerastii and N. tenuis, favouring the first. Cannibalism was not significantly different among these mirid species. Our results show that D. cerastii has a greater capacity to feed on intraguild prey than N. tenuis. Therefore, IGP on small nymphs does not explain the abundance shift between D. cerastii and N. tenuis.
Lithium has proven its efficacy in treating bipolar disorder. Severe side effects caused by lithium, including renal and endocrine outcomes, have already been amply documented. The impact of lithium on sexual function, however, is less well known. A 33-year-old man, with no past medical history, diagnosed with bipolar disorder, developed premature ejaculation after short-term use of lithium. The dose of lithium was reduced, leading to a rapid clinical resolution. Retrospectively, lithium-induced premature ejaculation was deemed the most likely diagnosis. Premature ejaculation is a rare side effect of lithium. Changing the time of medication administration and lowering dose could be considered as alternatives. Given lithium’s pharmacological profile, it is likely that the pathophysiologic mechanism behind premature ejaculation is altered levels or altered serotonin receptor sensitivity in the ejaculatory modulating centers of the central nervous system. Given the reluctance to spontaneously report sexual adverse effects, clinicians should be aware of this possible side effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
