Surgical Anatomy of the Rectovaginal Space: Does a Standalone Rectovaginal Septum or Denonvilliers Fascia Exist in Women?

Dis Colon Rectum 2021 May;64(5):576-582

1 Surgical Anatomy Unit, Department of Human Anatomy and Embryology, Faculty of Medicine and Dentistry. University of Valencia, Spain 2 European Center for Colorectal Surgery, Coloproctology Unit, Vithas Valencia, Valencia, Spain 3 Department of General and Digestive Surgery, Coloproctology Unit, University General Hospital Consortium, Valencia, Spain 4 Department of General and Digestive Surgery, Coloproctology Unit, Son Espases University Hospital, Palma de Mallorca, Spain.

Background: Below the anterior peritoneal reflection, the anterior rectal wall and mesorectum are separated from the posterior vaginal wall by a virtual rectovaginal space. In this space, the description of a specific and independent rectovaginal septum as a female counterpart of Denonvilliers fascia has been the subject of debate over the years.

Objective: The aim of this study is to perform an accurate anatomical study of the rectovaginal area in a cadaveric simulation model of total mesorectal excision to evaluate the possible structures and the dissection planes contained within the rectovaginal space. Read More

A new non-aggregative splicing isoform of human Tau is decreased in Alzheimer's disease.

Acta Neuropathol 2021 May 2. Epub 2021 May 2.

Centro de Biología Molecular "Severo Ochoa" (CSIC-UAM). Nicolás Cabrera, 1. Cantoblanco, 28049, Madrid, Spain.

Tauopathies, including Alzheimer's disease (AD) and frontotemporal lobar degeneration with Tau pathology (FTLD-tau), are a group of neurodegenerative disorders characterized by Tau hyperphosphorylation. Post-translational modifications of Tau such as phosphorylation and truncation have been demonstrated to be an essential step in the molecular pathogenesis of these tauopathies. In this work, we demonstrate the existence of a new, human-specific truncated form of Tau generated by intron 12 retention in human neuroblastoma cells and, to a higher extent, in human RNA brain samples, using qPCR and further confirming the results on a larger database of human RNA-seq samples.

Comprehensive Cancer Center, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Largo Agostino Gemelli 8, 00168 Rome, Italy.

Recently, retrospective analysis began to shed light on metastatic colorectal cancers (mCRCs) harboring rare non-V600 mutations, documenting a distinct phenotype and a favorable prognosis. This study aimed to confirm features and prognosis of rare non-V600 mCRCs compared to V600E and wild-type mCRCs treated at two Italian Institutions. Overall, 537 cases were retrospectively evaluated: 221 wild-type, 261 mutated, 46 V600E and 9 non-V600. Read More

Update on the Diagnostic Pitfalls of Autopsy and Post-Mortem Genetic Testing in Cardiomyopathies.

Int J Mol Sci 2021 Apr 16;22(8). Epub 2021 Apr 16.

Department of Health Surveillance and Bioethics, Section of Legal Medicine, Fondazione Policlinico A. Gemelli IRCCS, Università Cattolica del Sacro Cuore, 00168 Rome, Italy.

Inherited cardiomyopathies are frequent causes of sudden cardiac death (SCD), especially in young patients. Despite at the autopsy they usually have distinctive microscopic and/or macroscopic diagnostic features, their phenotypes may be mild or ambiguous, possibly leading to misdiagnoses or missed diagnoses. In this review, the main differential diagnoses of hypertrophic cardiomyopathy (e. Read More

Diagnostics (Basel) 2021 Apr 15;11(4). Epub 2021 Apr 15.

Unità di Ginecopatologia e Patologia Mammaria, Dipartimento Scienze della Salute della Donna, del Bambino e di Sanità Pubblica, Fondazione Policlinico Universitario A. Gemelli IRCCS, Largo A. Gemelli 8, 00168 Roma, Italy.

Colonization of breast carcinoma by non-neoplastic melanocytes of epidermal origin was first described by Azzopardi and Eusebi in 1977. We herein report two cases on the exceptional clinical and pathological features of this phenomenon in a 66-year-old and a 51-year-old patients. The pathogenesis is not fully understood, but a disrupted basement membrane and the role of tumoral growth factors are considered essential. Read More

Histone Epigenetic Signatures in Embryonic Limb Interdigital Cells Fated to Die.

Cells 2021 Apr 15;10(4). Epub 2021 Apr 15.

Departamento de Anatomía y Biología Celular, Instituto de Investigación Sanitaria Marqués de Valdecilla (IDIVAL), Universidad de Cantabria, 39011 Santander, Spain.

During limb formation in vertebrates with free digits, the interdigital mesoderm is eliminated by a massive degeneration process that involves apoptosis and cell senescence. The degradation process is preceded by intense DNA damage in zones located close to methylated DNA, accompanied by the activation of the DNA repair response. In this study, we show that trimethylated histone 3 (H3K4me3, H3K9me3, and H3K27me3) overlaps with zones positive for 5mC in the nuclei of interdigital cells. Read More

Recombinant IGF-1 Induces Sex-Specific Changes in Bone Composition and Remodeling in Adult Mice with Deficiency.

Int J Mol Sci 2021 Apr 14;22(8). Epub 2021 Apr 14.

Departamento de Anatomía Humana, Medicina Legal e Historia de la Ciencia, Instituto de Investigación Biomédica de Málaga (IBIMA), Universidad de Málaga, 29071 Málaga, Spain.

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), an IGF-1 availability regulator, causes postnatal growth failure and dysregulation of bone size and density. The present study aimed to determine the effects of recombinant murine IGF-1 (rmIGF-1) on bone composition and remodeling in constitutive knock-out (ko/ko) mice. To address this challenge, X-ray diffraction (XRD), attenuated total reflection-fourier transform infra-red (ATR-FTIR) spectroscopy and gene expression analysis of members of the IGF-1 system and bone resorption/formation were performed.

Targeting Protein Kinase C in Glioblastoma Treatment.

Biomedicines 2021 Apr 4;9(4). Epub 2021 Apr 4.

Instituto de Investigación e Innovación Biomédica de Cádiz (INiBICA), 11009 Cádiz, Spain.

Glioblastoma (GBM) is the most frequent and aggressive primary brain tumor and is associated with a poor prognosis. Despite the use of combined treatment approaches, recurrence is almost inevitable and survival longer than 14 or 15 months after diagnosis is low. It is therefore necessary to identify new therapeutic targets to fight GBM progression and recurrence. Read More

Astrocytic IGF-IRs induce adenosine-mediated inhibitory down regulation and improve sensory discrimination.

J Neurosci 2021 Apr 19. Epub 2021 Apr 19.

Departamento de Anatomía, Histología y Neurociencia, Facultad de Medicina, Universidad Autónoma de Madrid, Madrid, 28029, Spain

Insulin-like growth factor-I (IGF-I) signalling plays a key role in learning and memory processes. While the effects of IGF-I on neurons have been studied extensively, the involvement of astrocytes in IGF-I signalling and the consequences on synaptic plasticity and animal behavior remain unknown. We have found that IGF-I induces long-term potentiation (LTP, here called LTP) of the postsynaptic potentials that is caused by a long-term depression (LTD) of inhibitory synaptic transmission in mice.

R&D Department, APC EUROPE, S.L.U., Granollers, Barcelona, Spain.

Spray-dried animal plasma (SDAP) is widely used in diets of domestic animals to improve health status and increase growth and feed efficiency. Individual steps in the SDAP manufacturing process, including spray-drying, have been validated to inactivate potential pathogens. Manufacturing standards have established a minimum exit temperature of 80°C and a minimum post-drying storage period of 14 days at 20°C for production of SDAP. Read More

Distinct cytological mechanisms for food availability in three Inga ingoides (Fabaceae)-Cecidomyiidae gall systems.

Protoplasma 2021 Apr 28. Epub 2021 Apr 28.

Instituto de Ciências Biológicas, Laboratório de Anatomia Vegetal, Departamento de Botânica, Universidade Federal de Minas Gerais, Caixa postal 486, Belo Horizonte, Minas Gerais, CEP: 31270-901, Brazil.

Gall cytological, metabolic, and structural traits are established due to the feeding habits of the associated galling herbivores, and sometimes are influenced by other organisms involved in the interaction. We tested this assumption on three gall morphotypes, the globoid, the lenticular, and the fusiform, induced by Cecidomyiidae on leaflets of Inga ingoides (Rich.) Willd. Read More
