Oculomotor nerve palsy, an unusual onset of polyarteritis nodosa.

Introduction: Cranial nerve involvement in polyarteritis nodosa(PAN) is underrecognized and rarely reported. The aim of this article is to review the available literature and present an example of oculomotor nerve palsy in the course of PAN.

Material And Methods: Evaluation of texts describing the analyzed problem using the terms "polyarteritis nodosa", "nerve", "oculomotor", "cranial nerve" and "cranial neuropathy" for searching the PubMed database was done.

SARS-CoV-2 variants induce distinct disease and impact in the bone marrow and thymus of mice.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has evolved to variants associated with milder disease. We employed the k18-hACE2 mouse model to study how differences in the course of infection by SARS-CoV-2 variants alpha, delta, and omicron relate to tissue pathology and the immune response triggered. We documented a variant-specific pattern of infection severity, inducing discrete lung and blood immune responses and differentially impacting primary lymphoid organs.

Possible relationship between hydroxychloroquine and electrocardiographic and echocardiographic abnormalities in patients with inflammatory rheumatic diseases--a monocentric study.

Objective: Hydroxychloroquine (HCQ) is used in the treatment of inflammatory rheumatic diseases and is considered a safe drug. The role of HCQ in the COVID-19 pandemic highlighted some deleterious cardiac effects of HCQ. We aim to evaluate the prevalence and development of cardiac-adverse events in HCQ-treated patients with inflammatory rheumatic diseases.

Androgens and low density lipoprotein-cholesterol interplay in modulating prostate cancer cell fate and metabolism.

Background: Androgens, the known drivers of prostate cancer (PCa), have been indicated as important metabolic regulators with a relevant role in stimulating lipid metabolism. Also, the relationship between obesity and the aggressiveness of PCa has been established. However, it is unknown if the androgenic hormonal environment may alter the response of PCa cells to lipid availability.

The Role of Hypoxia in Glioblastoma Radiotherapy Resistance.

Glioblastoma (GB) (grade IV astrocytoma) is the most malignant type of primary brain tumor with a 16 months median survival time following diagnosis. Despite increasing attention regarding the development of targeted therapies for GB that resulted in around 450 clinical trials currently undergoing, radiotherapy still remains the most clinically effective treatment for these patients. Nevertheless, radiotherapy resistance (radioresistance) is commonly observed in GB patients leading to tumor recurrence and eventually patient death.

Glutaminolysis is a metabolic route essential for survival and growth of prostate cancer cells and a target of 5α-dihydrotestosterone regulation.

Purpose: Resistance to androgen-deprivation therapies and progression to so-called castrate-resistant prostate cancer (CRPC) remain challenges in prostate cancer (PCa) management and treatment. Among other alterations, CRPC has been associated with metabolic reprogramming driven by androgens. Here, we investigated the role of androgens in regulating glutaminolysis in PCa cells and determined the relevance of this metabolic route in controlling the survival and growth of androgen-sensitive (LNCaP) and CRPC (DU145 and PC3) cells.

Investigating Glioblastoma Response to Hypoxia.

Glioblastoma (GB) is the most common and deadly type of primary malignant brain tumor with an average patient survival of only 15-17 months. GBs typically have hypoxic regions associated with aggressiveness and chemoresistance. Using patient derived GB cells, we characterized how GB responds to hypoxia.

IoT Sensing Platform as a Driver for Digital Farming in Rural Africa.

Small-scale farming can benefit from the usage of information and communication technology (ICT) to improve crop and soil management and increase yield. However, in order to introduce digital farming in rural areas, related ICT solutions must be viable, seamless and easy to use, since most farmers are not acquainted with technology. With that in mind, this paper proposes an Internet of Things (IoT) sensing platform that provides information on the state of the soil and surrounding environment in terms of pH, moisture, texture, colour, air temperature, and light.

Reuma.pt/vasculitis - the Portuguese vasculitis registry.

Background: The vasculitides are a group of rare diseases with different manifestations and outcomes. New therapeutic options have led to the need for long-term registries. The Rheumatic Diseases Portuguese Register, Reuma.

Siboglinidae Tubes as an Additional Niche for Microbial Communities in the Gulf of Cádiz-A Microscopical Appraisal.

Siboglinids were sampled from four mud volcanoes in the Gulf of Cádiz (El Cid MV, Bonjardim MV, Al Gacel MV, and Anastasya MV). These invertebrates are characteristic to cold seeps and are known to host chemosynthetic endosymbionts in a dedicated trophosome organ. However, little is known about their tube as a potential niche for other microorganisms.

DIVERSet JAG Compounds Inhibit Topoisomerase II and Are Effective Against Adult and Pediatric High-Grade Gliomas.

High-grade gliomas (HGGs) are aggressive primary brain tumors with local invasive growth and poor clinical prognosis in both adult and pediatric patients. Clinical response is compounded by resistance to standard frontline antineoplastic agents, an absence of novel therapeutics, and poor in vitro models to evaluate these. We screened a range of recently identified anticancer compounds in conventional adult, pediatric, and new biopsy-derived HGG models.
