Breastfeeding of the newborn may be preventative in many such cases.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136276620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The term \"organoid\" means \"organ-like.\" In many cases, the cells and cell structures give organoids abilities similar to those of the organs they resemble. Brain organoids, for example, develop layers of nerve cells (neurons) with signaling activity and even \"brain regions\" that resemble areas of the human brain. Currently, organoids created by researchers may bear a strong resemblance to a fully mature organ in certain respects, but crucial differences still exist. Intestinal organoids have a variety of cellular structures that resemble parts of the intestinal mucosa, but are typically the size of a pea and thus not nearly as large or complex as our intestinal tract. But even though they are small, or do not correspond one hundred percent to entire organs, scientists can learn a lot from organoids. Experts believe that organoids represent the \"next generation\" of biological tools for research, drug development and medicine. Liver Organoid engineering could play an important role in treating and curing classic homocysteinuria in childhood by resetting the disturbed function of cystathion beta synthetase activity in the implanted organoid liver. This manuscript focus on liver organoid research to date with special attention to classic homocysteinuria in childhood.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136276621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system is divided into two principal hubs; the premotor area in the frontal lobe and inferior parietal lobule(IPL). Mirror neurons play an essential role fundamentally in human social interaction, such as action observation, imitation, understanding the emotions of others, and a myriad of other sophisticated human behavior and thought processes as well as the theory of mind. Since people with Autism Spectrum Disorders (ASD) have disorders and defects in communication, social interaction, the theory of mind, etc . So it can be suggested that defects in the mirror neuron system (MNS) may be linked to disorders like ASD and also play an essential role in this phenomenon. In this review, we discuss this connection.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74566944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depression in older adults may present differently than in younger adults with more physical complaints. Diagnosis becomes even more challenging in the presence of delirium and dementia, which often overlap in an older adult with MDD. It is important to assess suicide risks in older adults with depressive symptoms. Psychotherapy is recommended for mild to moderate depression, while antidepressants should be considered for severe depression or when psychotherapy is not available.

Diabetes insipidus is a disease in which large volumes of dilute urine (polyuria) are excreted due to vasopressin (AVP) deficiency [central diabetes insipidus (CDI)]. These adipsic CDI patients are treated with desmopressin and adjusting the amount of daily water intake based on body weight measurement; but controlling the water balance is extremely difficult, and morbidity and mortality are shown to be high in these patients. However, the discovery of the intrinsic property of melanin to dissociate the water molecule marks a before and after in the diagnostic, study, and treatment of patients affected by Central diabetes insipidus. Working on eumelanin has usually been regarded as an intriguing, though sometimes frustrating experience. The molecular mechanism by which eumelanin dissipates the radiation it absorbs was not known until we discovered it (water dissociation) in 2002, during an observational study that began in 1990 and ended in 2002. The working hypothesis was to try to correlate the anatomical characteristics of the blood vessels that enter and leave the optic nerve and the three main causes of blindness in the world. This study allowed us to identify the unsuspected capacity of the human body to transform the energy of sunlight into chemical energy, through the dissociation of the water molecule, as in plants.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80754758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The COVID-19 pandemic increased the risk of anxiety due to the uncertainties related to vaccine efficacy and immune-suppressing disease-modifying therapies. PwMS were recruited from the Neurology Clinic of the Penn State Hershey Medical Center and asked to complete a demographic questionnaire and surveys on depression (MS-Beck Depression Inventory, MS-BDI) and the Hospital Anxiety and Depression Scale (HADS). The rationale for the study is to determine whether treatment modalities, age, and length of disease impacted anxiety and/or depression in PwMS. Data from 150 participants were included in the analyses. The overall mean age was 54.6 years with a 3.7:1 female:male ratio and mean length of disease of approximately 17 years. Mean scores of the HADS-D, and high scores (> 8) were 4.68 ± 0.3 and 10.0 ± 0.32, respectively, with no differences between males and females. The mean HADS-A score was 6.15 ± 0.36 with significant differences recorded between male and females. The mean high HADS-A score was 10.77 ± 0.40, with no differences between sexes. The mean MS-BDI score was 4.15 ± 0.7 with no differences between males and females. Analyses of anxiety scores in relationship to length of disease revealed no differences between males and females.

Neurotherapeutic approaches to PNI and repair have primarily focused on the enhancement of axonal regeneration, in terms of rate, axonal sprouting, and reconnection connectivity. Both electrical stimulation (ES) and treatment with androgens [e.g., testosterone propionate (TP)] have been demonstrated to enhance axonal sprouting, regeneration rate and functional recovery following PNI.

Following injury, some animals received either (1) no further treatment beyond implantation with empty Silastic capsules, (2) electrical nerve stimulation immediately after injury, (3) implantation with Silastic capsules filled with TP, or (4) electrical nerve stimulation immediately after injury as well as implantation with TP. All of these groups of axotomized animals also received bi-weekly electromyography (EMG) testing. Additional groups of intact untreated animals as well as a group of injured animals who received no further treatment or EMG testing were also included.
