Does the COVID-19 pandemic condition the delusional content of patients with psychosis? An observational study.

Introduction: The primary objective is to analyse the impact of the COVID-19 pandemic on the triggers of psychopathology and on the delusional content of patients with psychotic symptoms treated during the first three months of the pandemic in a tertiary hospital in Madrid.

Methods: We conducted a cross-sectional, observational and retrospective study of all patients attending the psychiatric emergency room (ER) between 11th March and 11th June 2020. Sociodemographic and clinical variables were included.

Electroconvulsive therapy, catatonia, deep vein thrombosis and anticoagulant treatment: a case report.

Electroconvulsive therapy (ECT) is considered an effective treatment for pharmacotherapy-resistant severe mental disorders. Catatonia is a complex syndrome characterised by important psychomotor disturbances. Deep vein thrombosis (DVT) and pulmonary embolism (PE) are frequent side effects of prolonged immobility in catatonic patients.

Hedgehog gene expression patterns among intrinsic subtypes of breast cancer: Prognostic relevance.

Purpose: Hedgehog (Hh) signaling is a crucial developmental regulatory pathway recognized as a primary oncogenesis driver in various human cancers. However, its role in breast carcinoma (BC) has been underexplored.

Methods: We analyzed the expression of several Hh associated genes in a clinical series and breast cancer cell lines.

Demand Analysis of a Psychiatric Emergency Room and an Adolescent Acute Inpatient Unit in the Context of the COVID-19 Pandemic in Madrid, Spain.

COVID-19 represents a serious threat to mental health worldwide. The aim of this study is to identify changes in adolescent psychiatry treatment demand in a tertiary hospital in Madrid during the first month (March 11 to April 11) after the pandemic declaration by the World Health Organization (WHO). We hypothesized that fear of contagion within COVID-19 may deter people from asking for psychiatric care.

The Amniote Oculomotor Complex.

The oculomotor (OM) complex is a combination of somatic and parasympatethic neurons. The correct development and wiring of this cranial pair is essential to perform basic functions: eyeball and eyelid movements, pupillary constriction, and lens accommodation. The improper formation or function of this nucleus leads pathologies such as strabismus.

FOXA2 mRNA expression is associated with relapse in patients with Triple-Negative/Basal-like breast carcinoma.

The FOXA family of transcription factors regulates chromatin structure and gene expression especially during embryonic development. In normal breast tissue FOXA1 acts throughout mammary development; whereas in breast carcinoma its expression promotes luminal phenotype and correlates with good prognosis. However, the role of FOXA2 has not been previously studied in breast cancer.

FoxP2 protein levels regulate cell morphology changes and migration patterns in the vertebrate developing telencephalon.

In the mammalian telencephalon, part of the progenitor cells transition from multipolar to bipolar morphology as they invade the mantle zone. This associates with changing patterns of radial migration. However, the molecules implicated in these morphology transitions are not well known.

Osteopontin Regulates VEGFA and ICAM-1 mRNA Expression in Breast Carcinoma.

Objectives: To analyze the regulatory role of osteopontin on biomarkers associated with cell survival, invasiveness, and angiogenesis mechanisms in a clinical series and breast cancer cell lines.

Methods: We analyzed by quantitative real-time polymerase chain reaction the messenger RNA (mRNA) expression of osteopontin, Bcl2, intercellular adhesion molecule 1 (ICAM-1), and vascular endothelial growth factor A (VEGFA) in several breast cancer cell lines and in 148 breast carcinomas classified into intrinsic subtypes.

Results: We found coexpression of osteopontin, Bcl2, ICAM-1, and VEGFA in triple-negative MDA-MB-468 and MDA-MB-231 cell lines.

Growth and differentiation factor 10 (Gdf10) is involved in Bergmann glial cell development under Shh regulation.

Growth differentiation factor 10 (Gdf10), also known as Bmp3b, is a member of the transforming growth factor (TGF)-ß superfamily. Gdf10 is expressed in Bergmann glial cells, which was investigated by single-cell transcriptional profiling (Koirala and Corfas, (2010) PLoS ONE 5: e9198). Here we provide a detailed characterization of Gdf10 expression from E14, the stage at which Gdf10 is expressed for the first time in the cerebellum, until P28.

Src, a potential target for overcoming trastuzumab resistance in HER2-positive breast carcinoma.

Background: Src is a non-receptor tyrosine kinase involved in signalling and crosstalk between growth-promoting pathways. We aim to investigate the relationship of active Src in response to trastuzumab of HER2-positive breast carcinomas.

Methods: We selected 278 HER2-positive breast cancer patients with (n=154) and without (n=124) trastuzumab treatment.

Association of increased osteopontin and splice variant-c mRNA expression with HER2 and triple-negative/basal-like breast carcinomas subtypes and recurrence.

Osteopontin, a secreted phosphoglycoprotein, promotes tumor progression through binding to integrins and CD44 cell receptors. Its overexpression has been correlated with metastasis and adverse outcome in several neoplasms. In breast carcinoma, osteopontin mRNA and its splicing variant-c, a suggested marker for transformed cells, have not been extensively analyzed.

Role of Shh in the development of molecularly characterized tegmental nuclei in mouse rhombomere 1.

Hindbrain rhombomeres in general are differentially specified molecularly by unique combinations of Hox genes with other developmental genes. Rhombomere 1 displays special features, including absence of Hox gene expression. It lies within the hindbrain range of the Engrailed genes (En1, En2), controlled by the isthmic organizer via diffusion of FGF8.

Dynamic expression patterns of Nkx6.1 and Nkx6.2 in the developing mes-diencephalic basal plate.

The components of the molecular codes needed to specify the different neuronal populations present in the basal neural tube are being identified. These codes become more intricate as we move to more anterior regions of the central nervous system. The aim of this study is to thoroughly analyze the expression pattern of Nkx6.

Manic fringe is not required for embryonic development, and fringe family members do not exhibit redundant functions in the axial skeleton, limb, or hindbrain.

Tight regulation of Notch pathway signaling is important in many aspects of embryonic development. Notch signaling can be modulated by expression of fringe genes, encoding glycosyltransferases that modify EGF repeats in the Notch receptor. Although Lunatic fringe (Lfng) has been shown to play important roles in vertebrate segmentation, comparatively little is known regarding the developmental functions of the other vertebrate fringe genes, Radical fringe (Rfng) and Manic fringe (Mfng).

Shh dependent and independent maintenance of basal midbrain.

Sonic hedgehog (Shh) is well known as the molecule responsible for the induction and maintenance of ventral neural tube structures. Recent data have shown that ventral neuronal populations react differentially to the amount of this morphogen not only in the spinal cord, but also in more rostral parts of the brain, like the midbrain. A dorsal expansion in the Shh expression domain modifies the differentiation program in this territory.

Oscillatory lunatic fringe activity is crucial for segmentation of the anterior but not posterior skeleton.

The Notch pathway plays multiple roles during vertebrate somitogenesis, functioning in the segmentation clock and during rostral/caudal (R/C) somite patterning. Lunatic fringe (Lfng) encodes a glycosyltransferase that modulates Notch signaling, and its expression patterns suggest roles in both of these processes. To dissect the roles played by Lfng during somitogenesis, a novel allele was established that lacks cyclic Lfng expression within the segmentation clock, but that maintains expression during R/C somite patterning (Lfng(DeltaFCE1)).

Rapid production of gene replacement constructs and generation of a green fluorescent protein-tagged centromeric marker in Aspergillus nidulans.

A method to rapidly generate gene replacement constructs by fusion PCR is described for Aspergillus nidulans. The utility of the approach is demonstrated by green fluorescent protein (GFP) tagging of A. nidulans ndc80 to visualize centromeres through the cell cycle.
