RESUMO
Alzheimer's disease is a progressive neurological disorder causing memory loss and cognitive decline. The underlying causes of cognitive deterioration and neurodegeneration remain unclear, leading to a lack of effective strategies to prevent dementia. Recent evidence highlights the role of neuroinflammation, particularly involving microglia, in Alzheimer's disease onset and progression. Characterizing the initial phase of Alzheimer's disease can lead to the discovery of new biomarkers and therapeutic targets, facilitating timely interventions for effective treatments. We used the AppNL-G-F knock-in mouse model, which resembles the amyloid pathology and neuroinflammatory characteristics of Alzheimer's disease, to investigate the transition from a pre-plaque to an early plaque stage with a combined functional and molecular approach. Our experiments show a progressive decrease in the power of cognition-relevant hippocampal gamma oscillations during the early stage of amyloid pathology, together with a modification of fast-spiking interneuron intrinsic properties and postsynaptic input. Consistently, transcriptomic analyses revealed that these effects are accompanied by changes in synaptic function-associated pathways. Concurrently, homeostasis- and inflammatory-related microglia signature genes were downregulated. Moreover, we found a decrease in Iba1-positive microglia in the hippocampus that correlates with plaque aggregation and neuronal dysfunction. Collectively, these findings support the hypothesis that microglia play a protective role during the early stages of amyloid pathology by preventing plaque aggregation, supporting neuronal homeostasis, and overall preserving the oscillatory network's functionality. These results suggest that the early alteration of microglia dynamics could be a pivotal event in the progression of Alzheimer's disease, potentially triggering plaque deposition, impairment of fast-spiking interneurons, and the breakdown of the oscillatory circuitry in the hippocampus.

Bacterial symbionts are crucial for the infectivity and success of entomopathogenic nematodes as biological control agents. The current understanding of the symbiotic relationships is limited by taxonomic uncertainties. Here, we used whole-genome sequencing and traditional techniques to reconstruct the phylogenetic relationships between all described Photorhabdus species and subspecies as well as 11 newly isolated symbiotic bacteria of Heterorhabditis nematodes, including the unreported bacterial partner of H. beicherriana. In silico DNA-DNA hybridization, orthologous average nucleotide identity and nucleotide sequence identity of concatenated housekeeping genes scores were calculated and set into relation with current cut-off values for species delimitation in bacteria. Sequence data were complemented with biochemical and chemotaxonomic markers, and ribosomal protein fingerprinting profiles. This polyphasic approach resolves the ambiguous taxonomy of Photorhabdusand lead to the proposal for the elevation of most of them into a higher taxon and the creation of several new taxa: 15 new species, one of which is newly described: Photorhabdus bodei sp. nov. (type strain LJ24-63T=DSM 105690T=CCOS 1159T) and the other 14 arise through the proposal of elevating already described subspecies to species, and are proposed to be renamed as follows: Photorhabdus asymbioticasubsp. australis as Photorhabdus australis sp. nov., Photorhabdus luminescenssubsp. akhurstii as Photorhabdus akhurstii sp. nov., Photorhabdus luminescenssubsp. caribbeanensis as Photorhabdus caribbeanensis sp. nov., Photorhabdus luminescenssubsp. hainanensis as Photorhabdus hainanensis sp. nov., Photorhabdus luminescenssubsp. kayaii as Photorhabdus kayaii sp. nov., Photorhabdus luminescenssubsp. kleinii as Photorhabdus kleinii sp. nov., Photorhabdus luminescenssubsp. namnaonensis as Photorhabdus namnaonensis sp. nov., Photorhabdus luminescenssubsp. noenieputensis as Photorhabdus noenieputensis sp. nov., Photorhabdus luminescenssubsp.laumondii as Photorhabdus laumondii sp. nov., Photorhabdus temperatasubsp. cinerea as Photorhabdus cinerea sp. nov., Photorhabdus temperatasubsp. khanii as Photorhabdus khanii sp. nov., Photorhabdus temperatasubsp. stackebrandtii as Photorhabdus stackebrandtii sp. nov., Photorhabdus temperatasubsp. tasmaniensis as Photorhabdus tasmaniensis sp. nov., and Photorhabdus temperatasubsp. thracensis as Photorhabdus thracensis sp. nov. In addition, we propose the creation of two new subspecies, one of which arises through the reduction of rank: Photorhabdus laumondii subsp. laumondii comb. nov. (basonym: P. luminescenssubsp. laumondii) and the second one is newly described: Photorhabdus laumondii subsp. clarkei subsp. nov. (type strain BOJ-47T=DSM 105531T=CCOS 1160T). Finally, we propose to emend the description of three species, which results from the proposal of elevating three subspecies to the species status: Photorhabdus asymbiotica, Photorhabdus temperata and Photorhabdus luminescens, formerly classified as Photorhabdus asymbioticasubsp. asymbiotica, Photorhabdus temperatasubsp.temperata and Photorhabdus luminescenssubsp. luminescens, respectively.

The effectiveness of pest and disease management in crops relies on knowledge about their presence and distribution in crop-producing areas. Aphids and whiteflies are among the main threats to vegetable crops since these hemipterans feed on plants, causing severe damage, and are also able to transmit a large number of devastating plant viral diseases. In particular, the widespread occurrence of aphid-transmitted viruses in cucurbit crops, along with the lack of effective control measures, makes surveillance programs and virus epidemiology necessary for providing sound advice and further integration into the management strategies that can ensure sustainable food production. This review describes the current presence and distribution of aphid-transmitted viruses in cucurbits in Spain, providing valuable epidemiological information, including symptom expressions of virus-infected plants for further surveillance and viral detection. We also provide an overview of the current measures for virus infection prevention and control strategies in cucurbits and indicate the need for further research and innovative strategies against aphid pests and their associated viral diseases.
RESUMO
Members of the fungal genus Morchella are widely known for their important ecological roles and significant economic value. In this study, we used amplicon and genome sequencing to characterize bacterial communities associated with sexual fruiting bodies from wild specimens, as well as vegetative mycelium and sclerotia obtained from Morchella isolates grown in vitro. These investigations included diverse representatives from both Elata and Esculenta Morchella clades. Unique bacterial community compositions were observed across the various structures examined, both within and across individual Morchella isolates or specimens. However, specific bacterial taxa were frequently detected in association with certain structures, providing support for an associated core bacterial community. Bacteria from the genus Pseudomonas and Ralstonia constituted the core bacterial associates of Morchella mycelia and sclerotia, while other genera (e.g., Pedobacter spp., Deviosa spp., and Bradyrhizobium spp.) constituted the core bacterial community of fruiting bodies. Furthermore, the importance of Pseudomonas as a key member of the bacteriome was supported by the isolation of several Pseudomonas strains from mycelia during in vitro cultivation. Four of the six mycelial-derived Pseudomonas isolates shared 16S rDNA sequence identity with amplicon sequences recovered directly from the examined fungal structures. Distinct interaction phenotypes (antagonistic or neutral) were observed in confrontation assays between these bacteria and various Morchella isolates. Genome sequences obtained from these Pseudomonas isolates revealed intriguing differences in gene content and annotated functions, specifically with respect to toxin-antitoxin systems, cell adhesion, chitinases, and insecticidal toxins. These genetic differences correlated with the interaction phenotypes. This study provides evidence that Pseudomonas spp. are frequently associated with Morchella and these associations may greatly impact fungal physiology.
RESUMO
Viral infections on cucurbit plants cause substantial quality and yield losses on their crops. The diseased plants can often be infected by multiple viruses, and their epidemiology may depend, in addition to the agro-ecological management practices, on the combination of these viral infections. Watermelon mosaic virus (WMV) is one of the most prevalent viruses in cucurbit crops, and Moroccan watermelon mosaic virus (MWMV) emerged as a related species that threatens these crops. The occurrence of WMV and MWMV was monitored in a total of 196 apical-leaf samples of watermelon and pumpkin plants that displayed mosaic symptoms. The samples were collected from 49 fields in three major cucurbit-producing areas in Spain (Castilla La-Mancha, Alicante, and Murcia) for three consecutive (2018-2020) seasons. A molecular hybridization dot-blot method revealed that WMV was mainly (53%) found in both cultivated plants, with an unadvertised occurrence of MWMV. To determine the extent of cultivated plant species and mixed infections on viral dynamics, two infectious cDNA clones were constructed from a WMV isolate (MeWM7), and an MWMV isolate (ZuM10). Based on the full-length genomes, both isolates were grouped phylogenetically with the Emergent and European clades, respectively. Five-cucurbit plant species were infected steadily with either WMV or MWMV cDNA clones, showing variations on symptom expressions. Furthermore, the viral load varied depending on the plant species and infection type. In single infections, the WMV isolate showed a higher viral load than the MWMV isolate in melon and pumpkin, and MWMV only showed higher viral load than the WMV isolate in zucchini plants. However, in mixed infections, the viral load of the WMV isolate was greater than MWMV isolate in melon, watermelon and zucchini, whereas MWMV isolate was markedly reduced in zucchini. These results suggest that the impaired distribution of MWMV in cucurbit crops may be due to the cultivated plant species, in addition to the high prevalence of WMV.
RESUMO
Tef [Eragrostis tef (Zucc.) Trotter], an allotetraploid cereal that is a staple food to over 60 million people in the Horn of Africa, has a high nutritional content and is resistant to many biotic and abiotic stresses such as waterlogging and drought. Three tef genotypes, Alba, Tsedey, and Quncho, were subjected to waterlogging conditions and their growth, physiology, and change in transcript expression were measured with the goal of identifying targets for breeding cultivars with improved waterlogging tolerance. Root and shoot growth and dry weight were observed over 22 days. Stomatal conductance and chlorophyll and carotenoid contents were quantified. Microscopy was used to monitor changes in the stem cross sections. Illumina RNA sequencing was used to obtain the expression profiles of tef under flooding and control conditions and was verified using qPCR. Results indicated differences in growth between the three genotypes. Waterlogged Tsedey plants grew higher and had more root biomass than normally watered Tsedey plants. Quncho and Alba genotypes were more susceptible to the excess moisture stress. The effects of these changes were observed on the plant physiology. Among the three tested tef genotypes, Tsedey formed more aerenchyma than Alba and had accelerated growth under waterlogging. Tsedey and Quncho had constitutive aerenchyma. Genes affecting carbohydrate metabolism, cell growth, response to reactive oxygen species, transport, signaling, and stress responses were found to change under excess moisture stress. In general, these results show the presence of substantial anatomical and physiological differences among tef genotypes when waterlogged during the early growth stage.

Se realizó un estudio descriptivo retrospectivo de 358 necropsias de fetos, mortinatos y neonatos, analizadas en el Departamento de Anatomía Patológica del hospital ginecoobstétrico Ramón González Coro, de Ciudad de La Habana, entre los años 1996 y 2004. Fueron descartados 144 casos que no cumplían los criterios de inclusión. Las anomalías encontradas se clasificaron sobre la base del sistema anatómico mayor afectado. Se comparó la información obtenida del examen sonográfico y el anatomopatológico, con el objetivo de establecer la relación entre el diagnóstico prenatal por ultrasonido y el estudio necrópsico. La coincidencia diagnóstica entre ambos métodos de estudio fue del 82,41 porciento. El grupo de malformaciones encontrado con mayor frecuencia en las necropsias, fueron las cerebroespinales, con un 30,99 porciento, de las cuales el 13,61 porciento eran defectos del tubo neural. En este grupo, el 100 porciento de las anencefalias se diagnosticó sonográficamente y el 73 porciento de las espinas bífidas. Evaluando posteriormente a partir del examen ultrasonográfico, se encontraron 199 casos con diagnóstico de una malformación específica y el sistema mayormente afectado, fue el cerebroespinal (34,14 porciento). De estos diagnósticos positivos, 133 casos revelaron hallazgos necrópsicos idénticos (81,1 porciento), y fueron las anomalías cerebroespinales y las cardiovasculares las que mostraron mayor exactitud diagnóstica. En 31 casos se describieron hallazgos adicionales, para un 18,9 porciento y de ellos, 54,83 porciento tuvieron significado clínico. El diagnóstico prenatal se realizó antes de las 26 semanas de gestación en el 81,4 porciento y en el 18,6 porciento, después que la paciente sobrepasó las 26 semanas.
This is a retrospective study of 358 necropsies of stilbirths and newborns, performed at the Pathological Department of the Ramón Gonzßlez Coro Hospital, in Havana, between 1996 and 2004. Anomalies found were classified according to the major anatomic system affected. The aim of the study was to compare the ultrasound prenatal diagnosis and the pathological findings after the necropsy. In 82,41 percent of the cases, there was a coincidence between the two methods. Brain and spinal anomalies were the most frequent (30,99 percent). In this group, ultrasound examination identified all cases of anencephaly and 73 percent of cases with spina bifida. The correlation between ultrasound examination and necropsy was higher in cases of brain and cardiovascular malformations. Prenatal diagnosis was done before 26 weeks gestation in 81,4 percent of cases.

Se realiza en Cuba el pesquisaje de malformaciones congénitas a gestantes desde 1982, y se evalúan los niveles de alfafetoproteína. Por esta razón se aplicó en Ciudad de La Habana, en el Departamento Provincial de Genética, una encuesta a 100 gestantes atendidas en este servicio por alfafetoproteína elevada, con el objetivo de evaluar los aspectos organizativos y el impacto psicosocial de este programa de pesquisaje. Se concluye que debe mejorar la información que se ofrece a la gestante sobre la utilidad de la prueba (el 18 % no había recibido información por parte del médico), aunque el 93 % evaluó bien el pesquisaje.
The screening of congenital malformations among pregnant women is conducted in Cuba Since 1982, and their alpha-fetoprotein levels are also evaluated. For this reason, a survey was applied to 100 pregnant women who receive attention at the Provincial Genetics Department, in Havana City, due to their elevated alpha-fetoprotein (AFP) with the objective of evaluating the organizational aspects and the psychosocial impact ot this screening program. It was concluded that the information given to the pregnant women about the usefulness of this should be improved (18 % of them had not received any information from the doctor), although 93 % of these patients considered the screening as good.
