Speech decoding from a small set of spatially segregated minimally invasive intracranial EEG electrodes with a compact and interpretable neural network.

. Speech decoding, one of the most intriguing brain-computer interface applications, opens up plentiful opportunities from rehabilitation of patients to direct and seamless communication between human species. Typical solutions rely on invasive recordings with a large number of distributed electrodes implanted through craniotomy.

A Search for Similar Patterns in Hair Trace Element and Mineral Content in Children with Down's Syndrome, Obesity, and Growth Delay.

The objective of the present study was to perform comparative analysis of hair trace element and mineral levels in children with Down's syndrome, growth delay, and obesity in order to reveal common and specific patterns. Hair Zn (14, 7, and 15%), Ca (38%, 24%, and 47%), and Mg (33%, 31%, and 49%) levels in children with Down's syndrome, obesity, and growth delay were lower than the respective control values. At the same time, patients with Down's syndrome and growth delay were characterized by 27% and 21%, as well as 24% and 20% lower hair Co as well as Cu content than healthy examinees.

Association between catatonia and levels of hair and serum trace elements and minerals in autism spectrum disorder.

The objective of the study was to investigate the association between catatonia in autism spectrum disorder (ASD) and the levels of hair and serum trace elements and minerals in children with ASD. The levels of hair and serum trace elements and minerals of boys suffering from ASD with (n = 30) and without (n = 30) catatonia, as well as 30 age- and sex-matched neurotypical controls were assessed using ICP-MS. Hair calcium (Ca) and selenium (Se) levels were lower in ASD patients as compared to the controls.

Hair Mineral and Trace Element Content in Children with Down's Syndrome.

The objective of the present study was to assess the level of minerals and trace elements in 40 children with Down's syndrome and 40 controls aged 1-2 years old. Hair mineral and trace element analysis was performed using inductively coupled plasma mass spectrometry. The obtained data demonstrate that hair levels of Mg, P, I, Cr, Si, Zn, and Pb in Down's syndrome patients exceeded the respective control values by 36, 36, 93, 57, 45, 28, and 54%, whereas hair mercury was more than twofold lower in children with Down's syndrome.

Trace element levels are associated with neuroinflammatory markers in children with autistic spectrum disorder.

The objective of the present study was to estimate the association between brain inflammatory markers and serum trace element levels as assessed by inductively coupled plasma mass spectrometry at NexION 300D. Leukocyte elastase (LE), α1-proteinase inhibitor (α1-PI) activity, anti-nerve growth factor-antibodies (anti-NGF-Ab), and anti-myelin basic protein-antibodies (anti-MBP-Ab) levels were assessed as inflammatory markers. The obtained data demonstrate that the increase in LE and α1-PI activity is associated with higher serum Cr and Cu levels, respectively.

Zinc deficiency as a mediator of toxic effects of alcohol abuse.

Objective: To review data on the role of ethanol-induced alteration of Zn homeostasis in mediation of adverse effects of alcohol abuse.

Methods: The scholarly published articles on the association between Zn metabolism and alcohol-associated disorders (liver, brain, lung, gut dysfunction, and fetal alcohol syndrome) have been reviewed.

Results: It is demonstrated that alcohol-induced modulation of zinc transporters results in decreased Zn levels in lungs, liver, gut, and brain.

Comparative Hair Trace Element Profile in the Population of Sakhalin and Taiwan Pacific Islands.

The objective of the current study is to perform a comparative analysis of hair trace element content in 393 apparently healthy adults living in Taipei, Taiwan, Republic of China (94 women and 46 men) and Yuzhno-Sakhalinsk, Sakhalin, Russia (186 women and 67 men). The obtained data indicate that Yuzhno-Sakhalinsk inhabitants were characterized by significantly higher hair Co, Cr, Mn, and V levels, exceeding the respective Taipei values by a factor of 3, 2, 7, and 5, respectively (all p < 0.001).

ICP-DRC-MS analysis of serum essential and toxic element levels in postmenopausal prediabetic women in relation to glycemic control markers.

Purpose: Assessment of the influence of prediabetes on serum trace element and electrolyte levels in postmenopausal women.

Methods: A total of 80 prediabetic and 80 healthy postmenopausal women took part in the present study. Serum was analyzed for glucose, insulin, insulin resistance index (HOMA-IR), total cholesterol (TC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase (GGT).

Assessment of gender and age effects on serum and hair trace element levels in children with autism spectrum disorder.

The primary objective of the present study was to investigate the levels of essential trace elements in hair and serum in children with autism spectrum disorder (ASD) and investigate the age and gender effects. Children with ASD were characterized by significantly higher levels of copper (Cu) (+8%), iron (Fe) (+5%), and selenium (Se) (+13%) levels in hair and only 8% higher serum Cu levels. After stratification for gender, ASD boys were characterized by significantly increased hair Cu (+ 25%), Fe (+ 25%), and Se (+ 9%) levels, whereas in girls only Se content was elevated (+ 15%).

Comparative Analysis on the Effect of Plantago Species Aqueous Extracts on Tissue Trace Element Content in Rats.

Decreased adipose tissue zinc content is associated with metabolic parameters in high fat fed Wistar rats.

Background: Limited data on adipose tissue zinc content in obesity exist. At the same time, the association between adipose tissue zinc content and metabolic parameters in dietary-induced obesity is poorly studied. Therefore, the primary objective of this study is to assess adipose tissue zinc content and its association  with morphometric parameters, adipokine spectrum, proinflammatory cytokines, and apolipoprotein profile in high fat fed Wistar rats.

Evaluation of tissue metal and trace element content in a rat model of non-alcoholic fatty liver disease using ICP-DRC-MS.

The primary objective of the study was to assess the level of metals and trace elements in liver, serum, and hair of rats with diet-induced non-alcoholic fatty liver disease (NAFLD) using inductively coupled plasma dynamic reaction cell mass spectrometer (ICP-DRC-MS). 56 female 3-months-old Wistar rats divided into two equal groups were fed either standard (10% calories from fat) or high-fat high-carbohydrate diet (60% calories from fat in chow and 10% sucrose solution) for 6 weeks. Serum was examined for insulin resistance markers, lipid profile, and alanine aminotransferase (ALT) activity.
