Obesity is on the rise around the world, carrying along with it a wide range of comorbidities and complications. We report on a super-super morbidly obese 43-year-old female, with a body mass index (BMI) of 77.85 kg/m2 (173cm, 233kg), who presented for a scheduled suboccipital craniectomy with C-1 laminectomy secondary to symptoms from an Arnold-Chiari type-I malformation. Already a challenging type of surgery, due to the patient’s extreme BMI and positioning, the surgery became more difficult. There are many poten [...]

The story of each individual is essentially the story of theirlearning processes and relationships from the moment they were born. Indeed, the story of learning processes is merely a constant stratification of experiences based on biological and neurofunctional features that are influenced by genetic and cultural factors and subject to environmental stimuli constantly reshaping their behavior. Neuroscientific studies conducted over the past decades have highlighted a unique feature of the human nervous system, cal [...]

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 [...]

The present report discusses brain visual experiences in conditions of low degree of openness of the brain toward the environment, for example, while dreaming, during meditation, or in non-ordinary brain activity states such as under the effects of psychoactive substances, in the state of coma, or in other states of reduced sensory perception, among others. In the present report, for brevity, such states are referred to as brain-mind visual experiences, implying that such a visual activity is not one connected to t [...]

Data available on possible associations of lipids, steroid levels, and depression are conflicting. This study investigated their possible associations in a sample of youth with depression. Ninety-eight youth with depression and individually matched healthy volunteers on the basis of age and sex were enrolled for the study. The two groups had nearly similar body mass index. After fasting overnight, they underwent blood sampling for triglycerides (TG), total cholesterol, low-density lipoprotein, high-density lipoprot [...]

In this paper, motivated by the fading effect in wireless communications, where severe channel fading is related to information loss during the transmission, we evaluate and analyze the fading effect in time-varying functional connectivity of AD, MCI and NC subjects based on the resting-state fMRI data, and then apply that for AD, MCI, NC classification. We show that in some critical brain regions, compared with NC subjects, AD subjects suffer more severe and long lasting fading in the functional connectivity level [...]

Mechanisms leading to neuronal cell death in human pathology are far from being fully delineated. Understanding the molecules involved in neuronal death and the timing of their recruitment might help to explain the natural history of degenerative processes, including the morphological abnormalities observed in Alzheimer’s disease (AD). Moreover, it might help refine the diagnosis by defining new molecular markers as well as find effective therapies, especially for slow cognitive deficits, often associated with neur [...]

Temporomandibular disorders (TMD) are a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joint (TMJ), the masticatory muscles, and branches of the trigeminal nerve. TMD is the most common chronic oral facial pain disorder. Pain associated with TMD can be clinically expressed as myogenous or arthrogenous in etiology. The myogenous variant of TMD is characterized by pain in the muscles of mastication. The arthrogenous form of TMD is caused by pain in the joint leading to synovi [...]

Alzheimer’s disease (AD) causes severe cognitive dysfunction and has long been studied for the underlining physiological and pathological mechanisms. Several biomedical imaging modalities have been applied, including MRI, PET, and high-resolution optical microscopy, for research purposes. However, there is still a strong need for imaging tools that can provide high spatiotemporal resolutions with relatively deep penetration to enhance our understanding of AD pathology and monitor treatment progress in fundamental r [...]

Anorexia nervosa is a psychiatric disorder, the etiopathogenesis of which is still not fully understood. Currently, the most accredited model is a multifactorial model, which involves interaction between predisposing factors of biological nature, partly genetically determined, and psychological/personological and environmental socio-cultural factors. The last 20 years have led to the advancement in our knowledge on the mechanisms of energy homeostasis maintenance. There has been a veritable explosion of studies aim [...]
