Females of the ectoparasitoid Habrobracon hebetor attack and envenomate numerous host individuals during oviposition. The vectoring of the entomopathogenic fungus Beauveria bassiana during the adhesion stage by ectoparasitoid females among the wax moth larvae Galleria mellonella was explored under laboratory conditions. Vectoring occurred both from infected parasitoids to wax moth larvae and from infected to healthy wax moth larvae by parasitoids. The efficacy of vectoring in both cases was dose dependent. Parasitoid females were unable to recognize infected larvae in a labyrinth test...

BACKGROUND: An extended endoscopic endonasal approach is increasingly used in surgical treatment of space-occupying skull base lesions. The international literature reports only 20 cases of surgical treatment for fibrous dysplasia (PD) of the skull base using the endoscopic endonasal approach. We present our experience with the endoscopic endonasal approach in surgical treatment for giant fibrous dysplasia of the skull base, spreading to the right orbital cavity and nasopharynx. CLINICAL CASE: A 26-year-old male patient presented with cranial pain, Vth nerve dysfunction on the right, right keratopathy...

The nature and causes of psychiatric disorders are controversial and subject to debate, with theories changing according to historical, scientific, political, social and cultural contexts. In the past, hereditarian hypotheses stumbled in front of the lack of knowledge of genetics, the complexity of genetic-environmental interactions and the controversies of phenotypic definitions, still unresolved. The burst of genomics gave hopes to those who believe that the causes of psychiatric disorders is in the genes and who, armed with DNA sequencers and bioinformatics, began comparing genomic sequences among patients and controls, looking for associations with diverse phenotypes which remain inadequately defined...

INTRODUCTION: Physical and mental changes associated with aging commonly lead to a decrease in communication capacity, reducing social interactions and increasing loneliness. Computer classes for older adults make significant contributions to social and cognitive aspects of aging. Games in a virtual reality (VR) environment stimulate the practice of communicative and cognitive skills and might also bring benefits to older adults. Furthermore, it might help to initiate their contact to the modern technology...

Human subjects placed in strong magnetic fields such as in an MRI scanner often feel dizzy or vertiginous. Recent studies in humans and animals have shown that these effects arise from stimulation of the labyrinth and are accompanied by nystagmus. Here, we measured the three-dimensional pattern of nystagmus using video eye tracking in five normal human subjects placed in a 7T MRI to infer which semicircular canals are activated by magnetic vestibular stimulation. We found that the nystagmus usually had a torsional as well as a horizontal component...

Drip irrigation is a water-saving technology. To date, little is known about how biofilm forms in drippers of irrigation systems. In this study, the internal dripper geometry was recreated in 3-D printed microfluidic devices (MFDs). To mimic the temperature conditions in (semi-) arid areas, experiments were conducted in a temperature controlled box between 20 and 50°C. MFDs were either fed with two different treated wastewater (TWW) or synthetic wastewater. Biofilm formation was monitored non-invasively and in situ by optical coherence tomography (OCT)...

BACKGROUND: Vertigo or dizziness is a common occurrence, but it remains a challenging symptom when encountered in the emergency department (ED). A diagnostic score for stroke with high accuracy is therefore required. METHODS: A single-center observational study (498 patients) was conducted. The predictor variables were derived from a multivariate logistic regression analysis with Akaike information criterion. The outcome was the occurrence of stroke. We evaluated the utility of a new diagnostic score (TriAGe+) and compared it with the ABCD2 score...

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by autoantibody production against platelets, increased platelet destruction, and, in some cases, impaired thrombopoiesis. The majority of affected patients have significant bleeding risks due to low platelet counts and require treatment. The etiology of ITP is an immunological labyrinth. Currently available treatment options are usually not only nonspecific, but are also associated with some risks. Areas covered: Several useful drugs for the treatment of ITP are currently available...

A fundamental challenge to the brain is how to prevent intrusive movements when quiet is needed. Unwanted limb movements such as tremor impair fine motor control and unwanted eye drifts such as nystagmus impair vision. A stable platform is also necessary to launch accurate movements. Accordingly, nature has designed control systems with agonist (excitation) and antagonist (inhibition) muscle pairs functioning in push-pull, around a steady level of balanced tonic activity, the set-point Sensory information can be organized similarly, as in the vestibulo-ocular reflex, which generates eye movements that compensate for head movements...

Aims Labyrinthectomized rats are suitable models to test consequences of vestibular lesion and are widely used to study neural plasticity. We describe a combined microsurgical-chemical technique that can be routinely performed with minimum damage. Methods Caudal leaflet of the parotis is elevated. The tendinous fascia covering the bulla is opened frontally from the sternomastoid muscle's tendon while sparing facial nerve branches. A 4 mm diameter hole is drilled into the bulla's hind lower lateral wall to open the common (in rodents) mastoid-tympanic cavity...

Utero-placental (Ut-Pl) angiogenesis and blood flow are fundamental for successful outcome of pregnancy. They are controlled by numerous vasodilator and vasoconstrictor systems such as endothelins (EDNs) and the renin angiotensin system. Dogs possess an invasive type of placentation, classified as endotheliochorial. Despite increasing knowledge regarding canine Ut-Pl function, little information exists on uterine and placental vascular activity during initiation, maintenance and termination of pregnancy in this species...

Cholesteatoma is a destructive and expanding growth benign tumor, mainly consisting of stratified squamous epithelium. It possesses the capacity of eroding bone and can exist in a nonaggressive state, remaining undetected for years. Once cholesteatoma appeared, it grows relentlessly and threats to invade intra-temporal structures. Most cholesteatomas occurred in the petrous bone and also affected the labyrinth and middle cranial fossa. Here, we report a preliminary wrongly-diagnosed case. The patient was wrongly diagnosed as "sebaceous cyst with infection" by local hospital...

Noise-induced hearing loss (NIHL) is a global health problem affecting over 5% of the population worldwide. We have shown previously that acute noise-induced cochlear injury can be ameliorated by administration of drugs acting on adenosine receptors in the inner ear, and a selective A1 adenosine receptor agonist adenosine amine congener (ADAC) has emerged as a potentially effective treatment for cochlear injury and resulting hearing loss. This study investigated pharmacokinetic properties of ADAC in rat perilymph after systemic (intravenous) administration using a newly developed liquid chromatography-tandem mass spectrometry detection method...

The integration of inputs from vestibular and proprioceptive sensors within the central nervous system is critical to postural regulation. We recently demonstrated in both decerebrate and conscious cats that labyrinthine and hindlimb inputs converge onto vestibular nucleus neurons. The pontomedullary reticular formation (pmRF) also plays a key role in postural control, and additionally participates in regulating locomotion. Thus, we hypothesized that like vestibular nucleus neurons, pmRF neurons integrate inputs from the limb and labyrinth...

The need for mental health clinicians to practice cultural safety is vital in ensuring meaningful care and in moving towards improving the mental health outcomes for Aboriginal people. The concept of cultural safety is particularly relevant to mental health professionals as it seeks to promote cultural integrity and the promotion of social justice, equity and respect. A substantive theory that explained the experience of providing cultural safety in mental health care to Aboriginal patients was developed using grounded theory methodology...

OBJECTIVE: Integrins exert regulatory functions in placentogenesis. Null mutation of certain integrin α subunits leads to placental defects with subsequent fetal growth restriction or embryonic lethality in mice. So far, the placental role of α8 integrin remains to be determined. METHODS: Localization of α8 integrin and its ligands, fibronectin (FN) and osteopontin (OPN), was studied by immunohistochemistry in human, rat, and mouse placenta. The vascularization of the placental labyrinth layer of α8 integrin-deficient mice was determined by CD31 staining...

Paternally expressed 11/Retrotransposon-like 1 (Peg11/Rtl1) knockout (KO) mice show mid- to late fetal lethality or late fetal growth retardation associated with frequent neonatal lethality. The lethal phenotype is largely dependent on genetic background and becomes more severe with each succeeding generation in the course of backcross experiments to C57BL/6 (B6). We previously suggested that these lethal and growth phenotypes in the fetal stages were due to severe defects in placental fetal capillaries in the labyrinth layer...

The vestibular blood-labyrinth barrier (BLB) is comprised of perivascular-resident macrophage-like melanocytes (PVM/Ms) and pericytes (PCs), in addition to endothelial cells (ECs) and basement membrane (BM), and bears strong resemblance to the cochlear BLB in the stria vascularis. Over the past few decades, in vitro cell-based models have been widely used in blood-brain barrier (BBB) and blood-retina barrier (BRB) research, and have proved to be powerful tools for studying cell-cell interactions in their respective organs...
