In this study, we addressed the issue of data scarcity by constructing a large dataset (containing ~120,000 photographs) for the attention detection task. Then, by using this dataset, we established a powerful baseline system. In addition, we extended the proposed system by adding an auxiliary face detection module and introducing a unique GAN-based data augmentation technique. Experimental results revealed that the proposed system yields superior performance compared to baseline models and achieves an accuracy of 88% on the test set. Finally, we created a web application for testing the proposed model in real time.","PeriodicalId":74334,"journal":{"name":"OBM neurobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44239559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trévo is a multi-herbal supplement that provides various health benefits, including boosting the immune system and detoxification. In this study, we investigated the neuroprotective effects of Trévo against the neurotoxic effects of cadmium chloride (CdCl2). Thirty male Wistar rats were equally divided into three groups: Group I (normal control), Group II (administered CdCl2), and Group III (administered Trévo and CdCl2), and were used in the experiments. Animals were pretreated with 2 mL/kg of Trévo for five days and injected with Cd intraperitoneally 3 h later. Cd significantly increased the production of malondialdehyde (MDA), amyloidogenesis, activation of caspase 3 and 9, and the production of p53 and glutamate. It also inhibited the activity of Na+/K+ ATPase, glutamate dehydrogenase, catalase, superoxide dismutase, and glutathione-S-transferase. The administration of Trévo revealed its antioxidant, anti-amyloidogenic, anti-excitotoxicity, and anticholinesterase properties as it prevented the biochemical changes induced by Cd toxicity in the brain of male Wistar rats. Our results supported the reported health benefits of Trévo as a good dietary supplement in preventing the toxic effects of poisonous substances, such as cadmium.","PeriodicalId":74334,"journal":{"name":"OBM neurobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46060012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several pathogenetic hypotheses have been proposed, evidence favoring the role of aberrant neuroplasticity in the development of the neuropsychiatric symptoms associated with dementia is increasing. Specifically, agitation is resistant to treatment and affects the quality of life, also because of the lack of safe and effective treatment for AD. Alterations in pain processing due to plastic modifications occur during aging and neurodegeneration. Up to 80% of AD patients have chronic pain due to age-related comorbidities that are misdiagnosed and remain unattended due to a lack of self-reporting because of communication hindrance, which also contributes to the development of agitation. Here, we reported a strategy to target altered neuroplasticity for treating pain and agitation by applying bergamot essential oil with evidence for in-vivo analgesic effects on neuropathic and inflammatory pain preclinical models. Bergamot was engineered in a nanotechnology delivery system, NanoBEO, which provides the opportunity to investigate its efficacy in the NCT04321889 randomized, double-blind, placebo-controlled clinical trial BRAINAID. This trial can provide a rational basis for safe and effective treatment to alleviate agitation and pain, thus improving the quality of life of people suffering from AD.","PeriodicalId":74334,"journal":{"name":"OBM neurobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44586850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data on 684 migraine attacks reported by 68 adolescents aged 16 to 19 years were collected using an online platform and smartphone apps. A Fisher’s exact test was used to compare the distributions of the migraine attack frequency during vacation and school periods in two different scenarios. In both scenarios, the attack frequency during school periods was significantly higher than that during vacation periods. The use of web-based data collection has some methodological limitations; however, it enabled the measurement of relative migraine attack frequency in students during vacation and school periods. The higher prevalence of migraine during school periods indicates the requirement of increasing headache awareness among children.","PeriodicalId":74334,"journal":{"name":"OBM neurobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44525271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, loneliness needs to be studied in detail for intervention purposes. The UCLA Loneliness Scale is the most widely used measure of loneliness. However, the 20-item measure has some drawbacks, including questionnaire fatigue, especially when used with other measures, and a lack of accurate responses to all items. In this study, we evaluated two short forms of the UCLA Loneliness Scale used in other studies (UCLA-10 and UCLA-8), as well as a five-item version developed in this study, through the classical test theory and Mokken analysis with two different sample groups (teachers, N = 337; students, N = 355). The results of the Mokken analysis and the confirmatory factor analysis showed that the UCLA-10 and UCLA-5 were unidimensional and exhibited reliability and convergent validity. In contrast, the UCLA-8 was multidimensional and violated several assumptions of monotonicity and invariant item-ordering, although it showed satisfactory reliability and concurrent validity. All three versions of the scale correlated significantly with other indices of psychological well-being regarding concurrent validity, and the correlation coefficients were comparable to the coefficients of the 20-item version with the same variables. All three versions of the loneliness scale also demonstrated satisfactory convergent and discriminant validity. The results indicated that the UCLA-10 and UCLA-5 can be used as reliable and valid measures when the use of the long version of the UCLA Loneliness Scale is unsuitable.","PeriodicalId":74334,"journal":{"name":"OBM neurobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42921493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although most people have experienced pandemic-related fear and distress, certain groups who are on the front of service provision have experienced the pandemic in distinct ways, owing to its impact on the nature of their work. Schoolteachers represent one such group; therefore, it is imperative to identify resources that can safeguard against negative mental-health outcomes in schoolteachers. The current study investigated the potential protective role of sense of coherence (SOC) and resilience in the relationship between COVID-19 fear and loneliness. The participants were South African schoolteachers (N = 355); the participants completed the Fear of COVID-19 Scale, the University of California Loneliness Scale, the Connor-Davidson Resilience Scale-10, and the Sense of Coherence Scale-13. The results indicated that SOC and resilience had significant direct effects on loneliness, thereby suggesting their health-sustaining role. SOC and resilience also fully mediated the relationship between COVID-19 fear and loneliness. Therefore, although the provision of material resources is important, it is equally necessary to enhance people’s ability to comprehend, give meaning to, and manage the challenges associated with the pandemic. A salutogenic approach to mental health promotion in the workplace may be beneficial for enhancing SOC and resilience among schoolteachers.","PeriodicalId":74334,"journal":{"name":"OBM neurobiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48735906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
