Who Let the Dogs Out? Unmasking the Neglected: A Semi-Systematic Review on the Enduring Impact of Toxocariasis, a Prevalent Zoonotic Infection.

Toxocariasis remains an important neglected parasitic infection representing one of the most common zoonotic infections caused by the parasite Toxocara canis or, less frequently, by Toxocara cati. The epidemiology of the disease is complex due to its transmission route by accidental ingestion of embryonated Toxocara eggs or larvae from tissues from domestic or wild paratenic hosts. Even though the World Health Organization and Centers for Disease Control classified toxocariasis amongst the top six parasitic infections of priority to public health, global epidemiological data regarding the relationship between seropositivity and toxocariasis is limited. Although the vast majority of the infected individuals remain asymptomatic or experience a mild disease, the infection is associated with important health and socioeconomic consequences, particularly in underprivileged, tropical, and subtropical areas. Toxocariasis is a disease with multiple clinical presentations, which are classified into five distinct forms: the classical visceral larva migrans, ocular toxocariasis, common toxocariasis, covert toxocariasis, and cerebral toxocariasis or neurotoxocariasis. Anthelmintic agents, for example, albendazole or mebendazole, are the recommended treatment, whereas a combination with topical or systemic corticosteroids for specific forms is suggested. Prevention strategies include educational programs, behavioral and hygienic changes, enhancement of the role of veterinarians, and anthelmintic regimens to control active infections

A comparative assessment of building sustainability schemes in Norway

Various schemes are established to evaluate the sustainability of buildings during their life cycle. These schemes introduce a range of evaluation criteria and indicators and are periodically revised to align with current sustainability trends. This study reviews leading schemes in Norway, and compares their scope, similarities, limitations, and advantages. The review is carried out against a proposed office building in Oslo, Norway. The paper evaluates how the schemes comply with the EU taxonomy and Norwegian building regulations. The schemes are assessed through a literature review and interviews with programme operators. Common sustainability criteria are identified and reviewed. In addition, a comparison of how the schemes address the United Nations Sustainable Development Goals is conducted. The comparative assessment provides a valuable and practical reference and decision support for project owners in Norway to select the appropriate scheme for their construction project.publishedVersio

Indikatorer for klimatilpasning av arealer, bygninger og infrastruktur i kommuner. Testing i Trondheim kommune

Denne rapporten oppsummerer resultater i prosjektet Testing av indikatorer for klimatilpasning. Det er Trondheim kommune som har fått støtte fra Miljødirektoratet for å gjennomføre prosjektet. Prosjektet knyttet til seg en sommerstudent og SINTEF har vært forskningspartner. Prosjektet bygger på et rammeverk med indikatorer for klimatilpasning av bygninger og infrastruktur for kommuner, og i dette prosjektet har et utvalg av disse indikatorene blitt testet ut av relevante fagenheter i Trondheim kommune. Basert på erfaringene fra uttestingen ble det gjort en revisjon og oppdatering av rammeverket og foreslått nye indikatorer. Det er videre samlet inn data og beregnet indikatorverdier for de utvalgte indikatorene. Indikatorsettet i denne rapporten er utviklet i tett dialog og samspill med representanter fra klimatilpasningsgruppa i Trondheim kommune. Indikatorene har blitt vurdert etter ulike kriterier for egnethet, deriblant at indikatorene skal ha relevans for andre kommuner. Vi håper at små, mellomstore og store kommuner kan ta dette rammeverket i bruk, for å kunne følge opp og måle effekten av klima-tilpasningsarbeidet som gjøres i kommunen.publishedVersio

3D-визуализация в ультразвуковой дефектоскопии

На сегодняшний день существует множество средств визуализации ультразвуковых данных, но все они, как правило, интегрированы в дефектоскопы. Когда у нас возникает потребность извлечь данные сканирования, произвести собственную обработку, и представить в трехмерном изображении, то мы оказываемся лишенными возможности визуализации. Предложенное программное обеспечение на основе алгоритма SAFT позволяет произвести постобработку данных сканирования (А-сканов) и двумерную и трехмерную визуализацию

Zebrafish type I collagen mutants faithfully recapitulate human type I collagenopathies

The type I collagenopathies are a group of heterogeneous connective tissue disorders, that are caused by mutations in the genes encoding type I collagen and include specific forms of osteogenesis imperfecta (OI) and the Ehlers-Danlos syndrome (EDS). These disorders present with a broad disease spectrum and large clinical variability of which the underlying genetic basis is still poorly understood. In this study, we systematically analyzed skeletal phenotypes in a large set of zebrafish, with diverse mutations in the genes encoding type I collagen, representing different genetic forms of human OI, and a zebrafish model resembling human EDS, which harbors a number of soft connective tissues defects, typical of EDS. Furthermore, we provide insight into how zebrafish and human type I collagen are compositionally and functionally related, which is relevant in the interpretation of human type I collagen-related disease models. Our studies reveal a high degree of intergenotype variability in phenotypic expressivity that closely correlates with associated OI severity. Furthermore, we demonstrate the potential for select mutations to give rise to phenotypic variability, mirroring the clinical variability associated with human disease pathology. Therefore, our work suggests the future potential for zebrafish to aid in identifying unknown genetic modifiers and mechanisms underlying the phenotypic variability in OI and related disorders. This will improve diagnostic strategies and enable the discovery of new targetable pathways for pharmacological intervention

Human Cardiac-Derived Adherent Proliferating Cells Reduce Murine Acute Coxsackievirus B3-Induced Myocarditis

BACKGROUND: Under conventional heart failure therapy, inflammatory cardiomyopathy typically has a progressive course, indicating a need for alternative therapeutic strategies to improve long-term outcomes. We recently isolated and identified novel cardiac-derived cells from human cardiac biopsies: cardiac-derived adherent proliferating cells (CAPs). They have similarities with mesenchymal stromal cells, which are known for their anti-apoptotic and immunomodulatory properties. We explored whether CAPs application could be a novel strategy to improve acute Coxsackievirus B3 (CVB3)-induced myocarditis. METHODOLOGY/PRINCIPAL FINDINGS: To evaluate the safety of our approach, we first analyzed the expression of the coxsackie- and adenovirus receptor (CAR) and the co-receptor CD55 on CAPs, which are both required for effective CVB3 infectivity. We could demonstrate that CAPs only minimally express both receptors, which translates to minimal CVB3 copy numbers, and without viral particle release after CVB3 infection. Co-culture of CAPs with CVB3-infected HL-1 cardiomyocytes resulted in a reduction of CVB3-induced HL-1 apoptosis and viral progeny release. In addition, CAPs reduced CD4 and CD8 T cell proliferation. All CAPs-mediated protective effects were nitric oxide- and interleukin-10-dependent and required interferon-γ. In an acute murine model of CVB3-induced myocarditis, application of CAPs led to a decrease of cardiac apoptosis, cardiac CVB3 viral load and improved left ventricular contractility parameters. This was associated with a decline in cardiac mononuclear cell activity, an increase in T regulatory cells and T cell apoptosis, and an increase in left ventricular interleukin-10 and interferon-γ mRNA expression. CONCLUSIONS: We conclude that CAPs are a unique type of cardiac-derived cells and promising tools to improve acute CVB3-induced myocarditis

The SLC7A7 Transporter Identifies Microglial Precursors prior to Entry into the Brain

During development, macrophages invade organs to establish phenotypically and transcriptionally distinct tissue-resident populations. How they invade and colonize these organs is unclear. In particular, it remains to be established whether they arise from naive equivalents that colonize organs randomly or whether there are committed macrophages that follow pre-determined migration paths. Here, by using a combination of genetics and imaging approaches in the zebrafish embryo, we have addressed how macrophages colonize the brain to become microglia. Identification and cloning of a mutant that lacks microglia has shown that Slc7a7, a Leucine/Arginine transporter, defines a restricted macrophage sub-lineage and is necessary for brain colonization. By taking a photoconversion approach, we show that these macrophages give rise to microglia. This study provides direct experimental evidence for the existence of sub-lineages among embryonic macrophages

Microglia in the developing brain: from immunity to behaviour

For decades, microglia, the resident macrophages of the brain, have been recognized mostly for their role in several, if not all, pathologies affecting the brain. However, several studies under physiological conditions demonstrate that microglial function is indispensable also in the healthy brain. Indeed, microglia implement key functions already during development, such as the clearance of the huge amount of neurons that are produced in large excess in the embryo and later die of apoptosis. Beside these classical functions, however, novel roles are emerging that strikingly link microglia with higher order brain functions and show that these cells can ultimately influence behaviour. Therefore a detailed understanding of microglia under physiological conditions may open unprecedented perspectives in the prevention and treatment of neuropsychiatric diseases

Subacute Thyroiditis Complicating COVID-19 Infection

Subacute thyroiditis (SAT) is a self-limited inflammatory disease and a rare cause of thyrotoxicosis. Although the exact etiology of SAT is not sufficiently understood, it is generally associated to viral infections. Current evidence highlights that SAT may be a potentially uncommon manifestation of ongoing Coronavirus disease 2019 (COVID-19) infection or a post-viral complication of the disease. Despite that SAT is a rare manifestation associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease both in ongoing and resolved COVID-19 infection, the ever-increasing numbers of COVID-19 patients strengthens the possibility that this particular disease entity will be of more immediate concern in the future. The current work aims to summarize the approach of SARS-CoV-2-associated SAT, present its pathophysiology, outline current research evidence found in the literature, and discuss potential differential diagnoses and diagnostic dilemmas through an illustrative case

Stroke-heart syndrome: A case report and mini literature review

Despite the fact that cardiac troponin (cTn) elevation is commonly seen in the acute phase of ischemic stroke, investigating its etiology represents a challenge for healthcare practitioners. Therefore, we describe the case of an 86-year-old woman with dyspnea and cTn-elevation within the first days following acute ischemic stroke and discuss potential differential diagnoses and diagnostic dilemmas
