Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans contradict Vardy (2005) and justify full species status (Kurczewski 2023a). Furthermore, we propose the removal of the two species from the P. menechma list of synonyms and recommend full species reinstatement as Pepsis cerberus, restored status and Pepsis elegans, restored status. Pepsis menechma becomes a senior synonym of P. elegans. Morphometric re-examination and statistical analysis of P. cerberus and P. elegans structural features strongly support their reinstatement. Quantitative measurement of 10 parasitoid-related morphological characteristics of the females revealed the two species differ significantly in frons width/head width, head length/head width, vertex length/head width, vertex length/head length, flagellomere 1 length/flagellomere 1 width, forewing length/mesosoma width, and hind tibial inner spur length/hind basitarsus length. Pepsis cerberus and P. elegans females are structurally and statistically similar in gena-postgena corner radius, fore femur width/mesosoma width, and number of hind tibial serrations.

A new species of Paranthrene Hübner (Lepidoptera: Sesiidae) from the northern midwest United States
(2024)
A clearwing moth species, Paranthrene sogaardi Taft and Smith, 2024, new species, is described from Michigan and Minnesota. The recognition of this new species is based on a phylogeny estimated from mitochondrial cytochrome oxidase I and wingless DNA sequences of 25 specimens representing all Paranthrene Hübner species including individuals from various locations. Paranthrene sogaardi new species was monophyletic and differed from Paranthrene tabaniformis Rottenburg, 1775 by a mean of 7.6% COI pairwise “p” distance, coloration, and genitalic morphology.

The geographic distributions of three large wasps, Sphecius speciosus (Drury), Stictia carolina Fabricius and Stizus brevipennis Walsh (Hymenoptera: Crabronidae), occurring in Arkansas are defined using museum specimens and three internet-based data platforms. The internet-based data platforms generally provided more county location records than museum records. Using data from internet sources for easily identified species can better serve to illustrate the known distributions for some species thus making for a powerful tool elucidating distributional patterns and conservation planning.

Das Ziel der BMBF-finanzierten Forschungsprojekte „Nachhaltige Mobilität in Lincoln 1“ und „Nachhaltige Mobilität in Lincoln 2“ ist es, Erkenntnisse zu Veränderungen im Mobilitätsverhalten von Personen zu erlangen, die in ein autoreduziertes Quartier umziehen. Dazu wurden zwei aufeinander aufbauende Vollbefragungen der erwachsenen Bewohner*innen der autoreduzierten Lincoln-Siedlung in Darmstadt durchgeführt. Im Rahmen der ersten Befragung im Jahr 2020 wurden 1.140, im Rahmen der zweiten Befragungswelle, 2021, 1.614 Fragebögen verteilt. Der Rücklauf belief sich 2020 auf n = 166 (14,6 %), in 2021 auf n = 231 (14,3 %). Der vorliegende Bericht beschreibt das methodische Vorgehen im Rahmen der Befragungen. Hierfür wird auf das besondere Panel-Design der Studie eingegangen. Dieses ermöglicht sowohl Einblicke in den Umzug in die Siedlung, als auch in das Leben in der Siedlung im Verlauf eines Jahres, und die damit einhergehenden Veränderungen im individuelle Mobilitätsverhalten. Der Bericht stellt dazu die zentralen Inhalte des Fragebogens vor und erläutert die Durchführung der Befragungen. In deren Rahmen wurden die Bewohner*innen der Lincoln-Siedlung insgesamt dreimal kontaktiert. Um die Bereitschaft zur Teilnahme zu steigern, wurden im Vorfeld der Erhebungen mittels einer Pressemitteilung auf die Befragung aufmerksam gemacht und Ankündigungsschreiben in die Briefkästen der Bewohner*innen verteilt. Eine Woche nach der eigentlichen Fragebogenverteilung wurden Erinnerungsschreiben verteilt. Ferner geht der Methodenbericht auf den Umgang mit dem Rücklauf sowie auf die Datenaufbereitung und - eingabe ein, bevor die soziodemographischen Daten der Teilnehmer*innen auf ihre Repräsentativität geprüft werden.
We conducted a systematic review investigating the efficacy and tolerability of adrenocorticotropic hormone (ACTH) and corticosteroids in children with epilepsies other than infantile epileptic spasm syndrome (IESS) that are resistant to anti-seizure medication (ASM). We included retrospective and prospective studies reporting on more than five patients and with clear case definitions and descriptions of treatment and outcome measures. We searched multiple databases and registries, and we assessed the risk of bias in the selected studies using a questionnaire based on published templates. Results were summarized with meta-analyses that pooled logit-transformed proportions or rates. Subgroup analyses and univariable and multivariable meta-regressions were performed to examine the influence of covariates. We included 38 studies (2 controlled and 5 uncontrolled prospective; 31 retrospective) involving 1152 patients. Meta-analysis of aggregate data for the primary outcomes of seizure response and reduction of electroencephalography (EEG) spikes at the end of treatment yielded pooled proportions (PPs) of 0.60 (95% confidence interval [CI] 0.52–0.67) and 0.56 (95% CI 0.43–0.68). The relapse rate was high (PP 0.33, 95% CI 0.27–0.40). Group analyses and meta-regression showed a small benefit of ACTH and no difference between all other corticosteroids, a slightly better effect in electric status epilepticus in slow sleep (ESES) and a weaker effect in patients with cognitive impairment and “symptomatic” etiology. Obesity and Cushing's syndrome were the most common adverse effects, occurring more frequently in trials addressing continuous ACTH (PP 0.73, 95% CI 0.48–0.89) or corticosteroids (PP 0.72, 95% CI 0.54–0.85) than intermittent intravenous or oral corticosteroid administration (PP 0.05, 95% CI 0.02–0.10). The validity of these results is limited by the high risk of bias in most included studies and large heterogeneity among study results. This report was registered under International Prospective Register of Systematic Reviews (PROSPERO) number CRD42022313846. We received no financial support.
Key points
* Systematic review resulting in low to moderately solid evidence on the efficacy and tolerability of adrenocorticotropic hormone (ACTH) and corticosteroid treatment in children with epilepsy other than infantile spasms.
* Meta-analysis based on aggregate data from 2 controlled prospective, 5 uncontrolled prospective, and 31 retrospective studies.
* Pooled data showing a seizure response in 60% and electroencephalography (EEG) response in 56% of patients, with no major differences between drugs. However, 30%–40% of patients relapse after the cessation of treatment.
* The most frequent adverse effects are obesity and Cushing's syndrome, occurring in 70% of patients under continuous treatment for some weeks, but in less than 10% undergoing pulsed, intermittent regimens.
* More prospective, randomized-controlled studies are needed to improve the level of evidence and define the optimal doses and treatment duration.
Viruses that carry a positive-sense, single-stranded (+ssRNA) RNA translate their genomes soon after entering the host cell to produce viral proteins, with the exception of retroviruses. A distinguishing feature of retroviruses is reverse transcription, where the +ssRNA genome serves as a template to synthesize a double-stranded DNA copy that subsequently integrates into the host genome. As retroviral RNAs are produced by the host cell transcriptional machinery and are largely indistinguishable from cellular mRNAs, we investigated the potential of incoming retroviral genomes to directly express proteins. Here we show through multiple, complementary methods that retroviral genomes are translated after entry. Our findings challenge the notion that retroviruses require reverse transcription to produce viral proteins. Synthesis of retroviral proteins in the absence of productive infection has significant implications for basic retrovirology, immune responses and gene therapy applications.
Bipolar disorder (BD) is a heritable mental illness with complex etiology. While the largest published genome-wide association study identified 64 BD risk loci, the causal SNPs and genes within these loci remain unknown. We applied a suite of statistical and functional fine-mapping methods to these loci, and prioritized 22 likely causal SNPs for BD. We mapped these SNPs to genes, and investigated their likely functional consequences by integrating variant annotations, brain cell-type epigenomic annotations, brain quantitative trait loci, and results from rare variant exome sequencing in BD. Convergent lines of evidence supported the roles of SCN2A, TRANK1, DCLK3, INSYN2B, SYNE1, THSD7A, CACNA1B, TUBBP5, PLCB3, PRDX5, KCNK4, AP001453.3, TRPT1, FKBP2, DNAJC4, RASGRP1, FURIN, FES, YWHAE, DPH1, GSDMB, MED24, THRA, EEF1A2, and KCNQ2 in BD. These represent promising candidates for functional experiments to understand biological mechanisms and therapeutic potential. Additionally, we demonstrated that fine-mapping effect sizes can improve performance and transferability of BD polygenic risk scores across ancestrally diverse populations, and present a high-throughput fine-mapping pipeline (https://github.com/mkoromina/SAFFARI).
Two new species of Perinereis with single bar-shaped paragnaths on area VI (Group 1) from the rocky shores of Mumbai, Maharashtra, India, are described with barely (Subgroup 1A) or largely (Subgroup 1B) expanded proximal region of dorsal ligule in posterior parapodia. Perinereis malabarensis sp. nov. can be distinguished from the morphologically similar 1B species P. euiini Park & Kim, 2017 by the paragnath count in area I, the laterally isolated paragnaths in area III, and the length of the dorsal cirrus and dorsal ligule. Additionally, P. misrai sp. nov. is more similar to 1A species P. falsovariegata Monro, 1933 and P. villalobosi Rioja, 1947, but differs by the paragnath count in areas III–V and VII–VIII, the isolated paragnaths in area III, and the number of rows in the anterior band of areas VII–VIII. The morphological characters of the current 44 species within Perinereis G1 are compared, and an identification key to the species belonging to this group is also provided.
