Light-Activated Local Drug Delivery From Hydrogels: Potential for GBM Treatment

Received: 15 December 2020;  Published: 23 March 2021;  doi: 10.21926/obm.neurobiol.2101090

Abstract

Following post-operative treatment, the vast majority of GBMs recur, usually within 2 cm of the tumor resection margin. Since these tumors seldom metastasize outside the CNS, improved localized therapies should prove beneficial. Drug delivery systems (DDS) that allow control over drug release by an externally applied energy, such as light, have the potential of improving the results of chemotherapy. Light-activated hydrogel DDS, implanted in the operative cavity formed by tumor resection, bypasses the blood brain b [...]

Prenatal and Preimplantation Genetic Diagnosis of Huntington's Disease

Received: 15 December 2020;  Published: 28 January 2021;  doi: 10.21926/obm.neurobiol.2101085

Abstract

Huntington’s disease (HD) is an autosomal dominant disease that immensely impacts the affected families. However, the transmission of the disease from carriers to their offspring could be prevented. Prenatal diagnosis (PND) and preimplantation genetic diagnosis (PGD) are the only two available reproductive options for the carriers at risk to have disease-free children. PND for HD could be done through two kinds of genetic testing: direct and indirect. The same approaches are available for preimplantation genetic te [...]

Quantum Theory of EEG with Application to the Single-Trial ERP Analysis

Received: 17 July 2020;  Published: 27 January 2021;  doi: 10.21926/obm.neurobiol.2101084

Abstract

The probabilistic formalism of quantum mechanics is used to quantitatively link the electroencephalogram (EEG) with the underlying microscale activity of cortical neurons. Previous approaches applied methods of classic physics to reconstruct the EEG in terms of explicit physical models of cortical neurons and the volume conductor. However, the multiplicity of cellular processes with extremely intricate mixtures of deterministic and random factors prevented the creation of consistent biophysical parameter sets. To a [...]

N-Type Calcium Channels Control GABAergic Transmission in Brain Areas related to Fear and Anxiety

Received: 13 September 2020;  Published: 12 January 2021;  doi: 10.21926/obm.neurobiol.2101083

Abstract

N-type (Cav2.2) calcium channels are key for action potential-evoked transmitter release in the peripheral and central nervous system. Previous studies have highlighted the functional relevance of N-type calcium channels at both the peripheral and central level. In the periphery, N-type calcium channels regulate nociceptive and sympathetic responses. At the central level, N-type calcium channels have been linked to aggression, hyperlocomotion, and anxiety. Among the areas of the brain that are involved in anxiety a [...]

Abstract

Neurological tissue along with the cartilage remains one of the tissues that escapes human efforts of regeneration after injury. The human body, after an injury, can repair its tissues only to a certain extent that can help in recovering the function of organs. However, this is not the case in some organs, such as the brain and spinal cord. For a long time, basic medical science has been investigating the regeneration process that helps the human body, which is mainly through the pharmacological agents, proteins/ot [...]

Peripheral Nerve Dysfunction after Spinal Cord Injury

Received: 02 October 2020;  Published: 29 December 2020;  doi: 10.21926/obm.neurobiol.2004075

Abstract

Spinal cord injury (SCI) leads to an immediate loss of sensory and motor function below the level of injury mostly affecting people in the prime of life. In addition to the primary injury there is accumulating neurophysiological and histological evidence of dysfunction in the peripheral nerves, not related to direct damage from the primary injury, which exacerbates muscle wasting, and contributes to further functional loss and poor recovery. Among the potential contributing factors are systemic inflammation, and mo [...]

Neurostimulation Approaches in the Treatment of Severe Anorexia Nervosa

Received: 04 May 2020;  Published: 07 August 2020;  doi: 10.21926/obm.neurobiol.2003069

Abstract

Psychiatry is seeking interventions that could reliably sustain weight gain and psychosomatic recovery of patients with severe anorexia nervosa (AN). Currently, patients with AN, even after receiving individually-tailored therapeutic interventions, often relapse following marginal weight restoration. Also, the evidence regarding the effectiveness of psychotropic medications in relieving and treating AN symptomology is limited. The research in the field is aiming to mitigate shortcomings associated with common pract [...]

Abstract

Hypoxic-ischemic encephalopathy is a major cause of death and disability in the newborn period. Experimental models have demonstrated that brain injury in hypoxic-ischemic encephalopathy occurs in two phases: primary energy failure and secondary energy failure. In primary energy failure, there is a cessation of oxidative metabolism and irreversible neuronal injury, followed by secondary energy failure due to glutamate release, elevation of intracellular calcium, reactive oxygen species formation, apoptotic cell dea [...]

Neuroprotective Strategies in Glaucoma - Translation to Clinical Trials

Received: 16 April 2020;  Published: 15 June 2020;  doi: 10.21926/obm.neurobiol.2002062

Abstract

Neuroprotection in glaucoma is any medical treatment by which decline in visual function can be slowed or prevented by supporting the health and survival of neural cells, independent of lowering of intraocular pressure (IOP). This is achieved by targeting mechanisms to inhibit or delay retinal ganglion cell death and promote cell survival pathways. Despite demonstrating promising results in preclinical trials, many neuroprotective strategies have failed to show success in subsequent clinical trials. Of the clinical [...]

Catatonia Following Cessation of Topiramate in a Patient with Prader-Willi Syndrome: Case Report and Review of Literature

Received: 12 January 2020;  Published: 01 April 2020;  doi: 10.21926/obm.neurobiol.2002054

Abstract

Case studies have associated catatonia with withdrawal from benzodiazepines and clozapine, both of which have been shown to increase GABA activity. Long-term use of GABAergic medications could result in GABAA downregulation and sudden discontinuation of the GABAergic drug could lead to a GABA hypoactive state which could predispose the patient to catatonia. The anticonvulsant topiramate, is known to increase brain GABA activity. Prader-Willi syndrome (PWS) is a genetic imprinting disorder characterized by lack of e [...]

Abstract

Agitation is a common manifestation of acute brain injury. When not addressed, agitation can lead to slower recovery rates, including delayed admission to acute rehabilitation programs. Antipsychotics are commonly used to control agitation in acute brain injury in the ICU. However, there is no current consensus on the most "efficacious and safest strategy" for use of antipsychotics in acute TBI. Haloperidol is arguably the commonly used antipsychotic for agitation in ICU setting at present. Interestingly, there are [...]

Alzheimer’s Disease: Is a Dysfunctional Mevalonate Biosynthetic Pathway the Master-Inducer of Deleterious Changes in Cell Physiology?

Received: 03 October 2019;  Published: 29 November 2019;  doi: 10.21926/obm.neurobiol.1904046

Abstract

There is a growing awareness that the proteins—amyloid-beta (Aβ) and tau—do not cause Alzheimer’s disease (AD) but are produced as a result of it. Similarly, doubt reigns over the degree of causality of high plasma cholesterol and prenylation in AD. This review proposes a fresh and important perspective, in addition to the current line of thinking. It emerges from comparative analysis, in evolutionary retrospect, of the characteristics of the mevalonate biosynthetic pathways in insects versus [...]

Received: 22 August 2019;  Published: 16 September 2019;  doi: 10.21926/obm.neurobiol.1903040

Abstract

Microvascular endothelial dysfunction precedes, often by decades, the cognitive decline associated with Alzheimer's disease. Hence, preservation of a healthy cerebrovascular endothelium can be an important therapeutic target. By incorporating appropriate drug(s) into biomimetic (lipid cubic phase) nanocarriers, one obtains a multitasking combination therapeutic which targets certain cell-surface scavenger receptors, mainly class B type I (i.e., SR-BI), and crosses the blood-brain barrier. Documented similarities in [...]

Hyperglycemia-Induced Brain Injury in Preterm Infants

Received: 29 May 2019;  Published: 29 August 2019;  doi: 10.21926/obm.neurobiol.1903038

Abstract

Hyperglycemia soon after birth is common in extremely preterm infants. Hyperglycemia is associated with severe intraventricular hemorrhage and impaired neurodevelopmental outcome in these infants. Recent data in human infants and animal models demonstrate that hyperglycemia leads to decreased white matter content, abnormal synaptogenesis, microgliosis, and functional deficits in the absence of intraventricular hemorrhage. Data suggest that oxidative stress, inflammation, and abnormal substrate metabolism are respon [...]

Abstract

Aneurysmal subarachnoid hemorrhage (aSAH) causes serious brain injury, and its mechanisms have not been completely unraveled so far. The causative factors for the brain injury initiated by an aneurysm rupture, which is referred to as the early brain injury (EBI), include elevated intracranial pressure, cerebral hypoperfusion, and blood contents that are directly exposed to the brain surface. At Day 4–14 post aSAH, delayed cerebral ischemia (DCI) often develops, which may worsen the neurological outcomes critically. [...]

Abstract

Is it ethically permissible to sacrifice the life of one human being in order to save the lives of five others? This question forms the basis of the famous thought experiment called “the trolley problem.” Surveys have found that 90 percent of people agree it is permissible when the victim to be sacrificed is described as off in the distance, whereas the opposite result occurs if the victim is described as up close. No consistent ethical principle has been identified that account for these results. In this paper we [...]

Perspectives on the Role of Endocannabinoids in Autism Spectrum Disorders

Received: 11 April 2017;  Published: 27 April 2017;  doi: 10.21926/obm.neurobiol.1702005

Abstract

Autism spectrum disorders (ASDs) are diagnosed on the basis of three behavioral features, namely, (1) deficits in social communication, (2) absence or delay in language and (3) stereotypy. The consensus regarding the neurological pathogenesis of ASDs is aberrant synaptogenesis and synapse function. Further, it is now widely accepted that ASD is neurodevelopmental in nature, placing emphasis on derangements occurring at the level of intra- and intercellular signaling during corticogenesis. At present, there is an ev [...]

Neurobiology of Sleep and Microbiomics in Aging

Received: 22 February 2019;  Published: 12 April 2017;  doi: 10.21926/obm.neurobiol.1702003

Abstract

(1) Background: The daily rhythms of life on earth are governed by a central clock located in the hypothalamus and entrained primarily by light. By virtue of its connections to a myriad of other clocks located both in the brain and in peripheral organs and cells, this clock provides a timing signal based on the light/dark cycle by which organismal physiology and behaviour are governed. Disturbances of these natural rhythms have multiple downstream effects, frequently resulting in dysregulations of sleep and wake cy [...]

Perspectives on the Neurobiology of Antipsychotic Drugs in Psychiatric Disorders

Received: 22 February 2019;  Published: 14 March 2017;  doi: 10.21926/obm.neurobiol.1701001

Abstract

Antipsychotics have been a pillar in the treatment of schizophrenia since their introduction more than 60 years ago. Their variety in structures and receptor binding properties confers on them a complex clinical profile of effectiveness and risk of adverse side-effects. Although antipsychotics are best known for their therapeutic effects in schizophrenia, these are limited to the positive symptoms, with much less influence on negative symptoms or cognitive deficits. Moreover, although the newer (so-called second-ge [...]

Correlation between the Storage Pattern of Spent Fuel Casks and the Neutron Multiplication Factor

Received: 21 April 2025;  Published: 19 December 2025;  doi: 10.21926/jept.2504018

Abstract

The effective neutron multiplication factor (keff) of a fissile system is a function of space and time f(x, y, z, t), where (x, y, z) are the coordinates of the reference point in space, and t is time. The evidence of the time-dependence of the neutron multiplication factor of a fissile system was published in 2017. The spatial dependence is as important as the time dependence, as interacting arrays of fissile material during storage can lead to an increase in the system (keff). Therefore, evaluation of how the sto [...]
