A Ready-to-Use Data Analysis Pipeline for BioID Experiments Using Data-Dependent or Data-Independent Acquisition Mass Spectrometry.

Proximity labeling combined with mass spectrometry (MS)-based proteomics has become an essential tool in interactomics. Proximity-dependent biotin identification (BioID) is a versatile method for identifying interacting and neighboring proteins within their native cellular environments. In BioID, the target (bait) protein is fused to a mutated BirA tag that biotinylates vicinal proteins (preys), which are subsequently purified and analyzed using LC-MS/MS.

Blood proteome profiling for biomarker discovery in broilers with necrotic enteritis.

Analysis of the blood proteome allows identification of proteins related to changes upon certain physiological conditions. The pathophysiology of necrotic enteritis (NE) has been extensively studied. While intestinal changes have been very well documented, data addressing NE-induced alterations in the blood proteome are scant, although these might have merit in diagnostics.

Three Scales of Mental Health-Related Stigma: Additional Evidence on its Psychometric Properties in the Portuguese Population.

Introduction: The aim of this study was to provide additional evidence on the psychometric properties in the Portuguese population of three stigma scales: Mental Health Knowledge Schedule (MAKS), Scaling Community Attitudes Toward the Mentally Ill 12 (CAMI-12), and Reported and Intended Behaviour Scale (RIBS).

Methods: A total of 3556 participants were recruited and completed the three scales online. The study includes confirmatory factor analysis, internal consistency analysis, test-retest reliability, convergent validity, and known-groups validity tests.

Proteomics-Based Analysis of Laser-Capture Micro-dissected, Formalin-Fixed Paraffin-Embedded Tissue Samples.

The ability to bring spatial resolution to omics studies enables a deeper understanding of cell populations and interactions in biological tissues. In the case of proteomics, single-cell and spatial approaches have been particularly challenging, due to limitations in sensitivity and throughput relative to other omics fields. Recent developments at the level of sample handling, chromatography, and mass spectrometry have set the stage for proteomics to be established in these new disciplines.

Gla Rich Protein (GRP) Mediates Vascular Smooth Muscle Cell (VSMC) Osteogenic Differentiation, Extracellular Vesicle (EV) Calcification Propensity, and Immunomodulatory Properties.

Vascular calcification (VC) is a complex process involving vascular smooth muscle cell (VSMC) osteogenic differentiation, inflammation, and extracellular vesicle (EV) calcification and communication networks. Gla rich protein (GRP) is a calcification inhibitor involved in most of these processes. However, the molecular mechanism of GRP in VC and the specific characteristics, cargo, and functionality of calcifying EVs require further elucidation.

The effect of dosage on the protective efficacy of whole-sporozoite formulations for immunization against malaria.

Immunization with Plasmodium sporozoites, either attenuated or administered under the cover of an antimalarial drug, can induce strong protection against malaria in pre-clinical murine models, as well as in human trials. Previous studies have suggested that whole-sporozoite (WSpz) formulations based on parasites with longer liver stage development induce higher protection, but a comparative analysis of four different WSpz formulations has not been reported. We employed a rodent model of malaria to analyze the effect of immunization dosage on the protective efficacy of WSpz formulations consisting of (i) early liver arresting genetically attenuated parasites (EA-GAP) or (ii) radiation-attenuated sporozoites (RAS), (iii) late arresting GAP (LA-GAP), and (iv) sporozoites administered under chemoprophylaxis, that are eliminated upon release into the bloodstream (CPS).

Images that speak: A Portuguese Photovoice study on the psychosocial experience of a migrant population from Cape Verde after a first episode of psychosis.

Several migrant populations have been identified worldwide as high-risk groups for psychosis because of their experience of social adversity. Recent evidence suggests that the local contexts in which these populations live should be addressed in their complexity to take into account individual and larger societal environmental aspects. This study aimed to assess the lived experiences of a group of migrant Cape Verdean patients, who had been recently hospitalized for a first episode of psychosis in a mental health service on the outskirts of Lisbon, Portugal.

A genetically modified Plasmodium berghei parasite as a surrogate for whole-sporozoite vaccination against P. vivax malaria.

Two malaria parasite species, Plasmodium falciparum (Pf) and P. vivax (Pv) are responsible for most of the disease burden caused by malaria. Vaccine development against this disease has focused mainly on Pf.

Immunopeptidomics-based design of mRNA vaccine formulations against Listeria monocytogenes.

Listeria monocytogenes is a foodborne intracellular bacterial pathogen leading to human listeriosis. Despite a high mortality rate and increasing antibiotic resistance no clinically approved vaccine against Listeria is available. Attenuated Listeria strains offer protection and are tested as antitumor vaccine vectors, but would benefit from a better knowledge on immunodominant vector antigens.

Optineurin links Hace1-dependent Rac ubiquitylation to integrin-mediated mechanotransduction to control bacterial invasion and cell division.

Extracellular matrix (ECM) elasticity is perceived by cells via focal adhesion structures, which transduce mechanical cues into chemical signalling to conform cell behavior. Although the contribution of ECM compliance to the control of cell migration or division is extensively studied, little is reported regarding infectious processes. We study this phenomenon with the extraintestinal Escherichia coli pathogen UTI89.

Prevalence of the Most Frequent Neuropsychiatric Diagnoses in Hospitalized SARS-CoV-2 Patients Evaluated by Liaison Psychiatry: Cross-Sectional Study.

Introduction: The SARS-CoV-2 infection has been associated with the acute onset of mental and behavioural symptoms and psychiatric disorders. The aim of this study was to assess the prevalence of the different neuropsychiatric diagnoses in hospitalized patients with SARS-CoV-2 infection assessed by Liaison Psychiatry.

Material And Methods: We performed a cross-sectional study in a hospital near Lisbon, Portugal.

Proteome Profiling of RNF213 Depleted Cells Reveals Nitric Oxide Regulator DDAH1 Antilisterial Activity.

RNF213 is a large, poorly characterized interferon-induced protein. Mutations in RNF213 are associated with predisposition for Moyamoya disease (MMD), a rare cerebrovascular disorder. Recently, RNF213 was found to have broad antimicrobial activity and , yet the molecular mechanisms behind this function remain unclear.

Loss-of-Function Mutations in TRAF7 and KLF4 Cooperatively Activate RAS-Like GTPase Signaling and Promote Meningioma Development.

Meningiomas are the most common benign brain tumors. Mutations of the E3 ubiquitin ligase TRAF7 occur in 25% of meningiomas and commonly cooccur with mutations in KLF4, yet the functional link between TRAF7 and KLF4 mutations remains unclear. By generating an meningioma model derived from primary meningeal cells, we elucidated the cooperative interactions that promote meningioma development.

Identification of the MuRF1 Skeletal Muscle Ubiquitylome Through Quantitative Proteomics.

MuRF1 (TRIM63) is a muscle-specific E3 ubiquitin ligase and component of the ubiquitin proteasome system. MuRF1 is transcriptionally upregulated under conditions that cause muscle loss, in both rodents and humans, and is a recognized marker of muscle atrophy. In this study, we used in vivo electroporation to determine whether MuRF1 overexpression alone can cause muscle atrophy and, in combination with ubiquitin proteomics, identify the endogenous MuRF1 substrates in skeletal muscle.

Wernicke-Korsakoff Syndrome: A Case Series in Liaison Psychiatry.

Wernicke-Korsakoff syndrome (WKS) is a life-threatening and underdiagnosed neuropsychiatric condition caused by thiamine deficiency that comprises Wernicke encephalopathy and Korsakoff syndrome. Although mainly associated with chronic alcoholism, WKS can arise from other circumstances. This report describes a series of cases of WKS that were clinically evaluated by liaison psychiatrists on a nonpsychiatric inpatient unit.

Androgen-regulated transcription of drives alternative splicing patterns in prostate cancer.

Prostate is the most frequent cancer in men. Prostate cancer progression is driven by androgen steroid hormones, and delayed by androgen deprivation therapy (ADT). Androgens control transcription by stimulating androgen receptor (AR) activity, yet also control pre-mRNA splicing through less clear mechanisms.

Olanzapine-Induced Hyperprolactinemia: Two Case Reports.

Hyperprolactinemia is a common consequence of treatment with antipsychotics. It is usually defined by a sustained prolactin level above the laboratory upper level of normal in conditions other than that where physiologic hyperprolactinemia is expected. Normal prolactin levels vary significantly among different laboratories and studies.

The Impact of the "Semente" Program on the Family-Focused Practice of Mental Health Professionals in Portugal.

Children of parents with mental illness (COPMI) are a high-risk group. There is a strong association between parents' psychiatric disorders and the incidence of psychopathology in their children. These children need to be identified and supported by mental health workers early, and hence, clinical practice in adult mental health services needs to change from a focus on individual patients to a more systemic family focus.
