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.
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.

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.

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.

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.

Cardiac involvement is the most important predictor of mortality and it seems to be more frequent in anti-neutrophil cytoplasmic antibodies-negative patients. Cardiomyopathy and congestive heart failure can occur but a significant proportion of patients are asymptomatic.

Introduction: Tyrosine kinase inhibition of the epidermal growth factor receptor (EGFR) is the standard in the first line treatment of patients with advanced non-small-cell lung cancer (NSCLC) harbouring EGFR activating mutations. Here we aim to discern efficacy and toxicity measures through a meta-analysis of published studies that could aid treatment selection.
Materials And Methods: We performed a meta-analysis of the main randomized clinical trials evaluating the currently approved EGFR-TKIs in first-line of treatment of EGFR-positive advanced NSCLC.

A 35-year-old man presented with a 3-year history of arthralgia and purple coloration of the skin of his fingers and feet. Hand and foot radiography showed cystic bone lesions on phalanges suggestive of sarcoidosis. Lab tests revealed increased liver enzymes.

FISH is affected by a wide variety of abiotic and biotic variables and the way they interact with each other. This is translated into a wide variability of FISH procedures found in the literature.

Fluorescence in situ hybridization (FISH) employing nucleic acid mimics as probes is becoming an emerging molecular tool in the microbiology area for the detection and visualization of microorganisms. However, the impact that locked nucleic acid (LNA) and 2'-O-methyl (2'-OMe) RNA modifications have on the probe that is targeting microorganisms is unknown. In this study, the melting and hybridization efficiency properties of 18 different probes in regards to their use in FISH for the detection of the 16S rRNA of Helicobacter pylori were compared.

We developed a vaccine targeting the GBS glyceraldehyde-3-phosphate dehydrogenase (GAPDH), a glycolytic enzyme detected at the bacterial surface, which was proven to be effective in a neonatal mouse model of infection. Since this bacterium has emerged as an important pathogen in non-pregnant adults, here we investigated whether this vaccine also confers protection in an adult susceptible and in a diabetic mouse model of infection.

Glucans, mannans, pectic polysaccharides, arabinogalactans, fucoidans, galactans, hyaluronans, fructans, and xylans are polysaccharides with reported immunostimulatory activity. The structural features that have been related with such activity are the monosaccharide and glycosidic-linkage composition, conformation, molecular weight, functional groups, and branching characteristics.

This task is complex to achieve with moving platforms such as submersibles, towed or remotely operated vehicles (ROV), where the recording camera is typically not static and provides an oblique view of the seafloor. A new method for obtaining seabed surface area estimates is presented here, using the classical set up of two laser devices fixed to the ROV frame projecting two parallel lines over the seabed.
