Traditional assessments of public speaking skills rely on human scoring. We report an initial study the development automated scoring model for performances using multimodal technologies. Task design, rubric development, and rating were conducted according to standards in educational assessment. An corpus 17 speakers with 4 tasks was collected audio, video, 3D motion capturing devices. A based basic features speech content, delivery, hand, body, head movements significantly predicts rating,...

Depression is the most prevalent psychiatric disorder worldwide and remains incurable; however, there little research on its prevention. The leading cause of depression stress, music has been hypothesized to alleviate stress. To examine potential beneficial effects stress depression, we subjected mice chronic unpredictable mild (CUMS) during day at night. Strikingly, our results indicated that completely prevented CUMS-induced anxiety-like behaviors in mice, as assessed by open field, tail...

Addressing the urgent need for innovative depression treatments, this study heralds a breakthrough in major depressive disorder (MDD) therapy by intertwining clinical observations with neurobiological advancements. We analyzed brain-derived neurotrophic factor (BDNF) levels serum exosomes from diverse group of 60 individuals, including first-episode, drug-free MDD patients, medicated and healthy controls. Our results revealed significant decrease BDNF within patients’ exosomes, which notably...

Charcot-Marie-Tooth (CMT) neuropathies represent a heterogeneous group of peripheral nerve disorders affecting 1 in 2,500 persons. One variant, CMT1A, is primary Schwann cell (SC) disorder, and represents the single most common variant. In previous studies, we showed that neurotrophin-3 (NT-3) improved trembler(J) (Tr(J)) mouse also efficacy CMT1A patients. Long-term treatment with NT-3 was not possible related to its short half-life lack availability. This led considerations gene therapy...

Abstract There is an increasing risk of mental disorders, such as acute stress disorder (ASD), post-traumatic (PTSD) and depression among survivors who were trapped in rubble during earthquake. Such long-term impaction a single restraint has not been extensively explored. In this study, we subjected mice to 24-hour-restraint simulate the trapping episode, investigated (2 days after restraint) (35 impacts. Surprisingly, found that displayed depression-like behaviors, decreased glucose uptake...

As the popularity of video-based job interviews rises, so does need for automated tools to evaluate interview performance. Real world hiring decisions are based on assessments knowledge and skills as well holistic judgments person-job fit. While previous research scoring videos shows promise, it lacks coverage monologue-style responses structured (SI) questions content-focused rating. We report development a standardized video protocol human rating rubrics focusing verbal content,...

Abstract X-linked Charcot-Marie-Tooth neuropathy (CMTX) is caused by mutations in the gene encoding Gap Junction Protein Beta-1 (GJB1)/Connexin32 (Cx32) Schwann cells. Neurotrophin-3 (NT-3) an important autocrine factor supporting cell survival and differentiation stimulating axon regeneration myelination. Improvements these parameters have been shown previously a CMT1 model, Trembler J mouse, with NT-3 transfer therapy. For this study, scAAV1.tMCK.NT-3 was delivered to gastrocnemius muscle...

Delayed neurocognitive recovery (dNCR) is a common postoperative complication in geriatric surgical patients for which there no efficacious therapy. Cholecystokinin octapeptide (CCK-8), an immunomodulatory peptide, regulates memory and learning. Here, we explored the effects mechanism of action CCK-8 on dNCR.We applied laparotomy to establish model dNCR aged mice. Morris water maze fear conditioning tests were used evaluate cognition. Immunofluorescence was detect density CCK-8, A1 reactive...

The X-linked form of Charcot-Marie-Tooth neuropathy is associated with mutations in the connexin32 (Cx32) gene. functional role Cx32 Schwann cells and relationship these to progressive axonal loss distal limb weakness seen this disease have not been elucidated. To investigate local influence bearing gene defect on cytoskeleton myelination process, nerve xenograft model was used transfer a missense mutation (Glu102Gly) from human an vivo system nude mice.

X-Linked Charcot-Marie-Tooth disease is an inherited peripheral neuropathy arising in patients with mutations the gene encoding connexin 32 (Cx32). Cx32 expressed at paranodes and Schmidt-Lantermann incisures of myelinating Schwann cells which it believed to form a reflexive pathway between abaxonal adaxonal cytoplasmic domains. Patients Val181Ala (V181A) mutation have severe neuropathy. Experiments using nude mouse xenograft system show that expressing only this mutant are profoundly...

Postherpetic neuralgia (PHN), the most common complication of herpes zoster (HZ), plays a major role in decreased life quality HZ patients. However, neural mechanisms underlying PHN remain unclear. Here, using rat model at 2 weeks after varicella virus infection, we found that spinal astrocytes were dramatically activated. The mechanical allodynia and central sensitization significantly attenuated by intrathecally injected L-α-aminoadipate (astrocytic specific inhibitor) whereas minocycline...
