Published: May 2023

At the end of the 20th century, a geoinformation database on soil degradation in Russia, relied on the soil map of Russia at a scale of 1 : 5 million, was developed under the leadership of V.S. Stolbovoy. As part of the development of this problem and in the course of obtaining new information on soil degradation, an attempt was made to refine and supplement this database, that relies on the soil map of the Russian Federation 1 : 2.5 million scale. Soil degradation resulted from the impact of various types of pollution was taken into account, including industrial emissions, leakage of oil products, excessive application of pesticides, the impact of vehicles and radiation pollution. Each soil polygon of the soil map exposed to the pollution was characterized by the degree and area of pollution in accordance with the developed scales. The results of the analysis were used to construct cartograms illustrating the spatial distribution of chemical and radiation degradation of the country soils. According to the data obtained, in the zone of pollution derived from industrial enterprises and oil pollution, 20% of the soil-geographic polygons of the map are characterized by a strong degree of pollution, and 30% and 50% – by weak and medium, respectively. Agricultural pollution due to excessive use of plant protection products in Russia does not exceed 10% of the area of polygons and is characterized by a low degree. About 10% of the soil polygons of the basic soil map are heavily contaminated with radioactive contamination, while 40% and 50% of the polygons are moderately and weakly contaminated, respectively. Pollution from vehicles is weak and generally has low level. At the same time, megacities and highways with heavy traffic are distinguished by relatively high level of pollution.
El autoaprendizaje en la educación médica

“Dale un pez a un hombre hambriento y lo alimentarás durante un día, enséñale a pescar y lo alimentarás para toda su vida” (proverbio chino). Esta frase encaja perfectamente en uno de los modelos de aprendizaje más utilizados en los distintos niveles de la formación médica: el autoaprendizaje. Es principalmente en los estudios de posgrado donde se convierte en la principal estrategia didáctica para lograr los objetivos de aprendizaje. Se ha mencionado que no resolver una interrogante de nuestros estudiantes es invitarlos a la revisión y a la reflexión; y, por consecuencia, al aprendizaje. Pues parece que lo que realmente hacemos es lanzar a nuestros estudiantes hambrientos al mar a ver si pescan algo, y, además del riesgo de no pescar nada, existe el riesgo de que se ahoguen en el intento. Entonces, ¿qué hacer? Es una interrogante que trataremos de responder en este artículo.
Neuroprotective Effects of a Serotonin Receptor Peptide Follow-ing Sham vs. Mild Traumatic Brain Injury in the Zucker Rat
Authors: Grinberg Mihal , Burton Julia , Pang Kevin CH , Zimering Mark B 
Published: May 2023

Aims: Anxiety, major depressive disorder and accelerated cognitive decline frequently

complicate traumatic brain injury. Obesity and type 2 diabetes mellitus drive

peripheral inflammation which can accelerate traumatic brain injury-associated

neurodegeneration. The Zucker rat harbors G-protein coupled receptor agonist IgG

autoantibodies and in vitro neurotoxicity caused by these autoantibodies was prevented by a

novel synthetic fragment of the serotonin 2A receptor. The aim of the present study was to test

whether genetic obesity manifested in Zucker diabetic fatty rat is associated with anxiety,

depression and spatial memory impairment induced by mild traumatic brain injury. Furthermore,

we investigated whether these neurobehavioral or neurodegenerative complications can be

lessened by administration of a novel putative neuroprotective peptide.

Methods: Age-matched lean and fatty diabetic Zucker rats were tested in the sucrose

preference test (anhedonia), open field test in bright light (anxiety measure) and the Morris water

maze (spatial memory) prior to receiving a sham-injury or lateral fluid percussion (LFP) mild

traumatic brain injury. Behavioral testing was repeated at 1-week, 1-month, and 3-month

intervals following injury. A synthetic peptide consisting of a portion of the 5-

hydroxytryptamine (serotonin) 2A receptor (2 mg/kg) (or vehicle) was administered via

intraperitoneal route every other day for 7 days after sham or LFP injury to lean rats or 7 days

before and after sham or LFP injury to fatty rats.

Results: Sucrose preference decreased transiently (one week after mild traumatic brain injury) in Zucker lean rats indicative of anhedonia. Baseline anxiety-like behavior (bright light, open field test) was lower in fatty vs. lean Zucker rats, and anxiety behavior increased significantly in fatty rats but not lean rats following mild traumatic brain injury. Mild traumatic brain injury impaired recall of spatial memory in fatty and lean rats, and the effect was longer-lasting in fatty rats. A synthetic peptide fragment of the 5-hydroxytryptamine 2A receptor enhanced recall of
spatial learning one-week after sham injury in Zucker rats and it may have prevented ‘anhedonia’

one-week after TBI (LFP) in a subset of Zucker fatty and lean rats expressing near-normal

baseline sucrose preference. Mean plasma 5-hydroxytryptamine 2A receptor

autoantibody level (determined 2 weeks after injury) was 2.5-fold higher than background, but

did not differ significantly in (sham- vs TBI) Zucker lean rats.

Conclusions: These are the first data to suggest reduced baseline anxiety-like behavior in Zucker fatty (vs. lean) rats. The pronounced increases in anxiety , and spatial memory impairment experienced by Zucker fatty (vs lean) rats following mild traumatic brain injury may have accounted in part for absence of a 5-hydroxytryptamine 2A receptor peptide neuroprotective effect in brain- injured Zucker fatty rats.
