MPC category selection - individual analysis.

Researchers at the University of Texas Health Science Center at Houston (UTHealth), USA, used the "submillimeter" brain implant technology, has been able to determine which parts of the brain are associated with facial and scene recognition. The study was published on June 4 in the Cell subjournal Current Biology.

Traditionally, the hippocampus and parahippocampal gyrus, located in the medial temporal lobe (MTL), have been considered to be the primary regions of the recognition process. However, researchers have recently discovered that the memory network responsible for recognition extends beyond the MTL to include a deeper part of the brain called the medial Region of the parietal cortex (MPC).

Recently, Wei Zhu of South China University of Technology and Jeffrey Brinker of the University of New Mexico served as co-correspondents. Author, published in ACS Nano entitled: Biomimetic Rebuilding Modular Design Using Functional Components: Modular Design Using Functional Components The research paper.

The paper creates artificial red blood cells with similar properties to natural red blood cells that are stable in mice. exist for a longer period of time and can enable oxygen delivery, therapeutic drug delivery, magnetic targeting and toxin detection. The researchers first made synthetic cells by coating donated artificial red blood cells with a thin layer of silica. Positively and negatively charged polymers were then placed in layers on the silica-red blood cells, and the silica was etched away, thus Flexible replicas were produced. Finally, the research team covered the surface of the replicas with a membrane of natural red blood cells. The researchers loaded hemoglobin, anti-cancer drugs, toxin sensors, or magnetic nanoparticles onto the artificial red blood cells to demonstrate that they could shipping cargo. The study also showed that the artificial red blood cells could act as a bait for bacterial toxins.

Secondary injury from traumatic brain injury (TBI) can lead to lifelong disability. Mitochondria, as central mediators of the secondary injury cascade response to TBI, are important targets to prevent cell death and the spread of dysfunction. Cyclosporin A (CsA) maintains the functional integrity of mitochondria and is one of the most promising neuroprotective drugs for TBI.

Xiaoling Gao and Gan Jiang at Shanghai Jiao Tong University designed a lipoprotein bionic nanocarrier for delivery of CsA CsA was doped into the lipoprotein mimetic nanovector core and the matrix metalloproteinase-9-activatable cell-penetrating peptide was modified into the Surface of lipoprotein mimetic nanocarriers for targeted intracellular delivery of CsA.

4: Does frequent hearing loss always lead to the development of a mental disorder?No!

In most cases, subclinical psychiatric symptoms occur only transiently in adolescents or adults. However, in adults beyond the age of high onset of psychotic disorders (15-35 years), do speech auditory hallucinations occur only transiently? and the probability of conversion to mental disorders or other mental illnesses is not known. Professor Diederen's group from the University of Cambridge has conducted a study of the prevalence of frequent speech and hearing disorders in people over the age of high psychiatric risk. Individuals who were hallucinating and did not require mental health care were followed up for 5 years and the results were published in Psychological Medicine.

Studies have found that frequent verbal auditory hallucinations in the non-psychotic population over the age of high onset of psychiatric disorders are a highly stable symptoms, and may require mental health care. Baseline discomfort due to auditory hallucinations is a significant predictor of mental health care needs, while age, education, childhood psychological Trauma, etc. could not be predicted. Speech auditory hallucinations persisted in the majority of patients (86.4%) with no change in symptoms.

Recently, Alessandro Ori's research team from the Fritz Lippmann Institute-Leibniz Institute on Aging in Germany published a paper in the prestigious academic journal Cell Reports, using mass spectrometry-based proteomics to map the complete spatial composition of the protein profile of mouse small intestinal epithelial cells.

The study also reveals age- and region-specific differences in the composition of small intestinal crypt cells, and reveals the effects of aging and diet on the proteome of small intestinal epithelial cells, suggesting potential anti-aging effects of dietary interventions.

6, Irritability: a bellwether of suicidal tendencies in depressed patients ASCP2020

Irritability is strongly associated with suicidal ideation in adults with depression and should be addressed and assessed in clinical practice. Three studies of adults with depression and one study of adults with substance use disorder (SUD) have shown that irritability is associated with suicidal ideation. The strength of the correlation between irritability and suicidal ideation is even stronger than the correlation between severity of depressive symptoms and suicide.

"Irritability is an important component of depression in adults, but it is still poorly studied," says Dr. John W. K. K. K., of the Icahn School of Medicine at Mount Sinai, New York. Dr. Manish K. Jha points out, "If you look at the current diagnostic criteria, you will see that irritability is not an adult major symptom of depression; however, for patients under the age of 18, irritability is actually one of the top two symptoms. This study was published at the American Society of Clinical Psychopharmacology (ASCP) 2020 online annual meeting.

Does the way we think change when we are exposed to overt, observed situations? A research team led by Professor Hong Li from the Department of Psychology, School of Social Sciences, Tsinghua University recently published a paper in the top journal of psychology, Journal of Personality and Social Psychology published "How Do People Construe Objects When Being The article "Observed" answers this question. The study found that the presence of an observer activates an individual's higher level of construal. Changes in this level of constructs affect not only the way we see things, but also the way we express our priorities, the way we shop, and the way we feel. Look at a number of aspects of the product attributes and more.

8, Science Daily: The more you read when you're young, the slower your memory declines in old age!

A study from Georgetown University Medical Center, published in the June 5 issue of Science Daily, found that people who spend more time in early education have slower memory loss in old age.

The Georgetown University Medical Center, which is located at the heart of Georgetown University, is the world's largest medical center. (Center) is Dr. Michael Ullman, Professor in the Department of Neuroscience and Director of the Brain and Language Laboratory at the The study's lead leader, who said, "The short answer about the results of the experiment is that learning drives learning. There is evidence that women usually have better declarative memory than men, so early education leads to more knowledge."
