Effect of automated versus manual emergency braking on rear seat adult and pediatric occupant precrash motion.

Conclusions: Across all ages, head and trunk excursions were greater in MEB than AEB, despite increased muscle activity in MEB. This observation may suggest an ineffective attempt to brace the head or a startle reflex. The increased excursion in MEB compared to AEB may be attributed to differences in the acceleration pulses between the 2 scenarios. These results suggest that AEB systems can use specific deceleration profiles that have potential to reduce occupant motion across diverse age groups compared to sudden maximum emergency braking applied manually.

CONCLUSION: Veterans with dizziness symptoms use compensatory saccades in all planes of semicircular canal rotation, despite having normal peripheral VOR gain during rapid head rotation. The video head impulse test is a stable measure of vestibular slow phase and metrics of compensatory saccades in veterans with dizziness. PMID: 32083608 [PubMed - as supplied by publisher]

Authors: Monsanto RDC, Kasemodel ALP, Tomaz A, Abrahão Elias TG, Paparella MM, de Oliveira Penido N Abstract BACKGROUND: Evidence to support potential links between chronic otitis media (COM) and vestibular impairment/postural balance control issues is lacking. OBJECTIVE: To investigate whether COM associates with vestibular symptoms, balance problems, and abnormalities in vestibular function tests. METHODS: We selected patients with COM and excluded patients with any identifiable underlying causes for vestibular dysfunction. Fifty-two healthy volunteers were included as controls. All subjects underw...

MartinsAbstractTrypanosoma cruzi infection triggers an intense production of pro-inflammatory cytokines mediated by T helper 1 lymphocytes, inducing the anti-inflammatory reflex of acetylcholine (ACh). The ACh concentration modulation is associated to the two major esterases, the acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). AChE H353N protein polymorphism is related to low Chagas chronic disease prognost...

Vestibular failure or hypofunction can be generated by pathologies such as vestibular neuritis (VN), causing the onset of rotatory vertigo and the vestibulo-ocular reflex (VOR) hyporeaction. VN is a post-viral inflammation-producing vestibular nerve-axon impairment, which reaches compensation in 70% of cases. Here, we present two cases of vestibular failure that did not respond to pharmacological therapy, but did show modulated vestibular response after an osteopathic manipulative treatment. Dizziness handicap inventory (DHI) was used to assess disability, while VOR was examined by means of video head impulse test (v-HIT).

Multi-photon intravital microscopy (MP-IVM) is a powerful tool to image cells in vivo. Its application in immunology research has opened new horizons, allowing intravital imaging of leukocytes at the single cell level. A transparent cornea is vital to retain vision. As an immune privileged site, a quick innate response to foreign antigens is crucial in clearing opportunistic bacterial and viral pathogens and minimizing collateral structural damage to the cornea. Further, dissecting the mechanisms and preventing the rejection process after corneal transplantation is imperative to retain sight. Therefore, understanding the u...

ConclusionOur findings suggest that consumption of a cafeteria diet increases sympathetic drive to the heart but not to the blood vessels, independent of impairment in baroreflex and chemoreflex functions. Other mechanisms may be involved in the increased cardiac sympathetic drive, and compensatory vascular mechanisms may prevent the development of hypertension in this model of obesity.

In this study, we report on successful in vivo measurements of intraocular pressure in rabbits using an optical IOP measurement system. The sensor was implanted during cataract surgery in two New Zealand white (NZW) rabbits and tested in vivo for ten weeks. Prior to implantation, the sensors were characterized in vitro in the physiologically relevant pressure range of 0–60 mmHg. A portable wireless handheld reader consisting of an internal beam splitter, a monochromatic light source, and a digital single-lens reflex (DSLR) camera was also designed and implemented to capture interference patterns from the sensor. The ...

ConclusionsWe show that staining for AFB on BAL material in lung transplant patients had limited benefit when concurrent microbiology was performed. GMS staining shows a small benefit. We recommend reflex testing for fungal organisms but not mycobacterial organisms in lung transplant patients.

ConclusionsThe diameter of the recto-anal junction is increased to enable the passage of feces with high yield stress. The finite limits to such dilation likely contribute to fecal impaction. Hence, difficulties in defaecation may result either from unduly high yield stress or pathologies of reflex recto-anal dilatation or a combination of the two.

Authors: Chiba Y, Fukushima A, Nakao M, Kobayashi Y, Ishigaki T, Tenma T, Kamiya K, Shingu Y, Ooka T, Matsui Y, Anzai T Abstract A 23-year-old man had progressive muscle weakness and Emery-Dreifuss muscular dystrophy (EDMD) due to a LMNA (lamin A/C) mutation. Congestive heart failure diagnosed at 19 years of age. Maximal drug treatment/cardiac resynchronization failed to improve the cardiac function. He was therefore hospitalized due to heart failure. Despite extracorporeal membrane oxygenation, he developed severe right heart dysfunction and died (multiple organ failure). A cardiac lesion's presence determines the...
