Inactivated nanovaccine boosts T-cell memory response in a seropositive yellow-footed rock wallaby () - A case report from Copenhagen Zoo.

is a ubiquitous parasite causing significant mortality in captive wildlife, especially marsupials. Historically, treatment has been unrewarding and no vaccine was available. An intranasal vaccine based on purified inactivated was developed for toxoplasmosis prevention.

Nanoparticles with a Lipid Core Can Enhance the Infection of Epithelial Cells with an Enterovirus.

Introduction: The effect of maltodextrin-based nanoparticles with an anionic phospholipid core (lipid-based nanoparticles [NPLs]) on the infection of a human tumoral cell line with poliovirus (PV) has been studied.

Methods: NPLs were synthesized and associated with the PV type 1 Sabin strain, and the formulations were characterized. PV and PV/NPL formulations were inoculated to HEp-2 cells.

Maltodextrin-Nanoparticles as a Delivery System for Nasal Vaccines: A Review Article.

Nanoparticles are increasingly being studied as antigen delivery systems for immunization with nasal vaccines. The addition of adjuvants is still generally required in many nanoparticle formulations, which can induce potential side effects owing to mucosal reactogenicity. In contrast, maltodextrin nanoparticles do not require additional immunomodulators, and have been shown to be efficient vaccine delivery systems.

Understanding Barriers Impacting upon Patient Wellbeing: A Nationwide Italian Survey and Expert Opinion of Dermatologists Treating Patients with Moderate-to-Severe Psoriasis.

A nationwide cross-sectional online survey was administered to dermatologists managing patients with moderate-to-severe plaque psoriasis across Italy to obtain real-world dermatologists' perspectives on the impact of psoriasis and its treatment on patients' daily lives and quality of life (QoL). A total of 91 dermatologists (aged 39.1 ± 11.

Nasal vaccination of six squirrel monkeys (): Improved immunization protocol against with a nanoparticle-born vaccine.

is an intracellular protozoon found worldwide, which completes its life cycle between felids (its definitive host) and other warm-blooded animals. While the infection rarely leads to severe complications in humans, many animal species are very susceptible to this infection, for example the squirrel monkey () which is the subject of this study. Toxoplasmosis is lethal for 80% of cases in this species, and fatal outbreaks are frequently reported in zoological parks.

Effective immuno-therapeutic treatment of Canine Leishmaniasis.

Background: Canine Leishmaniasis (CanL) caused by the L. infantum species is one of the biggest threats to the health of the South American canine population. Chemotherapeutics currently used for the treatment of CanL fail to induce a total parasite clearance while inducing numerous side effects.

Problem behavior in autism spectrum disorders: A paradigmatic self-organized perspective of network structures.

Autism spectrum disorder (ASD) subjects can present temporary behaviors of acute agitation and aggressiveness, named problem behaviors. They have been shown to be consistent with the self-organized criticality (SOC), a model wherein occasionally occurring "catastrophic events" are necessary in order to maintain a self-organized "critical equilibrium." The SOC can represent the psychopathology network structures and additionally suggests that they can be considered as self-organized systems.

Diabetes progression and alterations in gut bacterial translocation: prevention by diet supplementation with human milk in NOD mice.

Impaired intestinal barrier function occurs before type 1 diabetes (T1D) onset with a possible contribution of microbial translocation. Breastfeeding is associated with enhanced mucosal intestinal integrity and T1D protection. Our aim was to study the potential of human milk (HM) to prevent diabetes onset and modulate the translocation of gut bacteria susceptible to breastfeeding or associated to diabetes onset.

The gastrointestinal-brain axis in humans as an evolutionary advance of the root-leaf axis in plants: A hypothesis linking quantum effects of light on serotonin and auxin.

Living organisms tend to find viable strategies under ambient conditions that optimize their search for, and utilization of, life-sustaining resources. For plants, a leading role in this process is performed by auxin, a plant hormone that drives morphological development, dynamics, and movement to optimize the absorption of light (through branches and leaves) and chemical “food” (through roots). Similarly to auxin in plants, serotonin seems to play an important role in higher animals, especially humans.

Bifidobacteria-derived lipoproteins inhibit infection with coxsackievirus B4 in vitro.

The aim of the present study was to investigate the potential of bifidobacteria in protecting cells from coxsackievirus B4 (CV-B4) infection. Bifidobacterial screening identified two of five strains that protected human epithelial type 2 (HEp-2) cell viability when bifidobacteria were incubated with viral particles prior to inoculation. In contrast, no effect was shown by incubating HEp-2 cells with bifidobacteria prior to CV-B4 inoculation.

Sphenoidal pneumosinus dilatans due to anterior skull base meningiomas - CT and MRI aspects: Report of two new cases and literature review.

We report on two patients disclosing a pneumosinus dilatans (PSD) and an anterior skull base meningioma. Our findings, together with those from the pertinent literature, support the thought that this infrequent anomaly of paranasal sinuses is a useful clue to suspect a concomitant meningioma. Moreover, hypotheses concerning the pathophysiology of PSD are discussed.

Extracranial internal carotid artery: anatomical variations in asymptomatic patients.

The anatomical variations of internal carotid artery (ICA) are mostly asymptomatic, thus being disregarded and only incidentally diagnosed, with very few symptomatic patients. The awareness of these anomalies is crucial to solve the differential with other neck lesions, preventing accidental injuries during neck surgery. Therefore, the aim of our study is to estimate the prevalence of ICA anomalies, using magnetic resonance angiography (MRA) and computed tomography angiography (CTA).

In silico mining and characterization of bifidobacterial lipoprotein with CHAP domain secreted in an aggregated form.

Bifidobacterium breve C50 secretes a lipoprotein associated with glucose, acting in an aggregating form (>600kDa) as an agonist of TLR2/6. Similar lipoproteins were sought for in bifidobacteria. In silico, the closest homology was shown with a Bifidobacterium longum protein containing CHAP and lipobox domains.

Bifidobacterium breve C50 secretes lipoprotein with CHAP domain recognized in aggregated form by TLR2.

Extracellular components secreted by Bifidobacterium breve C50 can induce maturation, high IL-10 production and prolonged survival of dendritic cells via a TLR2 pathway. In this study, the components were isolated from the supernatant by gel filtration chromatography. Antibodies raised against the major compounds with molecular weight above 600 kDa (Bb C50BC) also recognized compounds of lower molecular weight (200–600 kDa).

Cavernous malformations isolated from cranial nerves: Unexpected diagnosis?

Objectives: Cranial nerves (CN) cavernous malformations (CMs) are lesions that are isolated from the CNs. The authors present three cases of CN CMs, for which MR was demonstrated to be critical for management, and surgical resection produced good outcomes for the patients. Surgical removal is the recommended course of action to restore or preserve neurological function and to eliminate the risk of future haemorrhage.

Giant thrombosed intracavernous carotid artery aneurysm presenting as Tolosa-Hunt syndrome in a patient harboring a new pathogenic neurofibromatosis type 1 mutation: a case report and review of the literature.

Neurofibromatosis type 1 (NF1) is a relatively common single-gene disorder, and is caused by heterozygous mutations in the NF1 gene that result in a loss of activity or in a nonfunctional neurofibromin protein. Despite the common association of NF1 with neurocutaneous features, its pathology can extend to numerous tissues not derived from the neural crest. Among the rare cerebrovascular abnormalities in NF1, more than 85% of cases are of purely occlusive or stenotic nature, with intracranial aneurysm being uncommon.

Transient ischaemic attack: an exceptional presenting syndrome of a superior sagittal sinus thrombosis.

We report a case of a transient ischaemic attack (TIA) as an exceptionally rare form of cerebral vein thrombosis. A 41-year-old man presented with a headache and five episodes of a transient left hemiparesis lasting approximately 10-15 min over the course of 2 weeks. Arterial origins of the disease were ruled out by detailed investigations.

[Acustic neurinoma: correlation between clinic and MRI].

The purpose of this paper is to study acoustic neuroma diagnostic process, describe tumor's molecular basis and its magnetic resonance imaging characterization, which is considered to be the gold standard diagnostic tool to study this disease.

Solitary lumbar osteochondroma presenting with spinal cord compression.

We report a case of a middle-aged woman with a solitary osteochondroma of the L2 right lamina with intraspinal extension and spinal cord compression. The case is unusual in terms of localisation and age at clinical presentation. In fact, spinal osteochondromas as solitary lesions-especially when affecting the lumbar segment-are rare tumours of a maturing adolescent skeleton, infrequently affecting the neurological structures, because most of the lesions grow out of the spinal canal.

Giant frontal intraparenchymal schwannoma: unexpected diagnosis.

We report the case of an intraparenchymal frontal schwannoma, surgically resected in a middle-aged, otherwise healthy woman. Magnetic resonance imaging was ineffective for the definitive diagnosis and was instead afforded by histology. This case is unique because the rare lesion presented as a giant mass; to the best of our knowledge, such a finding has not been previously reported.

Lateral sellar angiolipomas: a therapeutic challenge. Our experience on two cases and review of the literature.

Angiolipomas are rare benign mesenchymal tumours, most commonly found in the subcutaneous tissue of the extremities. These neoplasms are rarely located in the central nervous system (CNS), with spinal localization being the most common in this group. Intracranial location is extremely infrequent, and only ten cases have been described in the sellar region.

Isolated transient blindness and isolated oculomotor nerve palsy secondary to single mesencephalic metastases: report of 2 cases.

Purpose: Metastatic lesions of midbrain are quite rare, and only unusually they produce isolated cranial nerve palsy.

Methods: We report two cases of 2nd and 3rd cranial nerves impairment, produced by solitary midbrain metastases.

Results: In both patients Magnetic Resonance (MR) allowed a correct diagnosis, subsequently confirmed by histology.

Computed tomography and magnetic resonance angiography in the evaluation of aberrant origin of the external carotid artery branches.

Aim of our study was to evaluate the prevalence of aberrant origin of the branches of the external carotid artery (ECA) in 97 patients by computed tomography (CTA) and magnetic resonance angiography (MRA) and to compare the accuracy of these two techniques in the visualization of the ECA system. All patients underwent CTA and MRA examination of the head and neck. Multiplanar and volumetric reformations were obtained in all cases.
