Authors: Dorofeeva Tatyana
Published: January 2021

The demographic situation has recently become one of the most important issues in modern Russia, which also affected the market of higher education service. The research objective was to analyze the demographic profile of Russia and the Kemerovo region. The author identified the impact of demographic and economic factors on the demand for higher education. A correlation analysis made it possible to select proper indicators in order to assess the impact of demographic and economic factors on the contingent of university students. The demographic factors included birth rate and the number of population aged 15–19. The economic factors were the average annual nominal salary and the average annual cost of education. The research revealed a positive correlation between the number of births, the amount of population aged 15–19, and the number of students in higher education institutions. Comparative and relative analyses made it possible to assess the paying capacity of population in the sphere of chargeable educational services, which showed an increase in the burden on the household budget and an increase in financial barriers to higher education. The research contributes to the development of the regional economy as it helps to predict the population's demand for higher education services.

Authors: Alexander Leon
Published: January 2021

The goals of cleft palate surgery are an effective barrier between the nasal and oral air passages leading to functional outcomes in terms of speech,
feeding and hearing for the affected child. But unfortunately, these goals are sometimes not easily attained and complicated by Cleft Palate Fistulas
(CPFs), which adversely affects not only the child but also the parents. The principles of cleft palate surgery include a two-layer, tension-free,
watertight closure with preservation of the greater palatine neurovascular pedicle. This article aims to give a broad review of the current
perspectives in the management of this distressing complication.

Non-small cell lung cancer is usually diagnosed at the advanced stage of the disease. We have novel
diagnostic tools. However, prevention is still the best way to deal with this disease. Patients receive different
treatments with different adverse effects. Targeted treatment with tyrosine kinase inhibitors and immunotherapy
have entered everyday clinical practice. The nutritional status of a patient plays a crucial role in the treatment
of the patient. Cachexia is observed in most cancer patients, and it has been identified as an independent
factor in the overall survival of the patient. The improvement of nutritional status and metabolism directly impacts
the quality of life, daily living, and overall survival of a lung cancer patient. We conducted a search on
PubMed and Scopus and identified relevant publications. In this review, we will focus on the nutritional status
of NSCLC patients and how food supplements assist in the QoL based on published literature. Additional information
from other cancer types will be included where necessary.
Prins-Friedel-Crafts Cyclization: Synthesis of Diversely Functionalized Six- Membered Oxacycles
Authors: Roy Snigdha
Published: January 2021

Prins cyclization is a well-established synthetic protocol to generate a wide range
of important oxygen heterocycles. It is a cyclization reaction performed by an oxocarbenium
ion that undergoes an intramolecular pi-bond attack to construct a new carbon-carbon bond.
When this cyclization process is conjugated with Friedel-Crafts reaction, it further expands
the synthetic potential by fabricating two different carbon-carbon bonds in one single reaction.
Different acid catalysts mediated the coupled Prins-Friedel-Crafts reaction which is conducted
both in stepwise as well as in tandem fashion. In the stepwise route, three different
reacting components were utilized whereas, the tandem methodology required proper modification
of the initial substrate molecule. An array of allylic, propargylic, other related alkenols,
and carbonyl reactants were employed to carry out the cyclization process. Several oxygenated
heterocycles equipped with diverse functionalities were constructed in a stereoselective manner which again
reinforced the significance of this cyclization protocol undoubtedly. The present mini-review highlights the utilization
of different one-pot stepwise Prins-Friedel-Crafts reactions and the subsequent development of cascade Prins-
Friedel-Crafts cyclization process to furnish intricate molecular architectures of vital six-membered oxacycles.
Experimental and Theoretical Approach to Novel Polyfunctionalized Isoxazole
Authors: Al-Azmi Amal , Shalaby Mona A.
Published: January 2021

A novel, fast, and straightforward procedure for the synthesis of di- and trifunctionalized
isoxazoles starting from 2-ethoxymethylenemalononitrile with different ratios
of hydroxylamine in the presence of sodium acetate is described in this paper. The current
method’s features include the availability of the starting materials, moderate reaction conditions,
and the simplicity of the workup. The structures are characterized using different spectroscopic
studies, such as infrared (IR), 1H/13C nuclear magnetic resonance (NMR), and elemental
analysis, in addition to X-ray single-crystal determination. The gauge-invariant atomic
orbital (GIAO) 1H and 13C NMR chemical shift values of 5-aminoisoxazole-4-carbonitrile and
3,5-diaminoisoxazole-4-carboxamide are calculated in the ground state using the density
functional theory (DFT) with the 6-311+G(d, p) basis set and are compared with the experimental
data, in addition to the calculation of the molecular electrostatic potential (MEP) distribution, and the frontier
molecular orbitals (FMOs) for the synthesized isoxazoles are illustrated theoretically.
HMG-CoA Reductase Inhibitors (Statins) and their Drug Interactions Involving CYP Enzymes, P-glycoprotein and OATP Transporters-An Overview
Authors: Balasubramanian Rajkapoor , Maideen Naina M.P.
Published: January 2021

Background:

Hydroxymethyl glutaryl-CoA (HMG-CoA) reductase inhibitors (Statins) are used to
treat dyslipidemia. Generally, the statins are the substrates of CYP enzymes, P-glycoprotein (P-gp), and organic
anion transporting polypeptides transporters (OATP1B1).

Objective:

This review article focuses on the clinical significance of statins, and their interactions in real practice.

Methods:

The databases like Medline/PubMed Central/PubMed, Google Scholar, Science Direct, Cochrane Library,
Directory of open access journals (DOAJ), and reference lists were searched to identify relevant articles.

Results:

Most of the drug interactions of statins result in elevated plasma concentrations and toxicity of statins
due to the inhibition of CYP3A4, P-gp and/or OATP1B1 transporters. The toxicity of statins includes myopathy,
rhabdomyolysis, elevated liver enzymes, acute kidney injury, and diabetes. The statins like simvastatin, lovastatin,
and atorvastatin are substrates of CYP3A4 enzyme and P-glycoprotein and their concomitant use with
the drugs inhibiting or inducing them would result in changes in plasma concentrations and toxicity/efficacy.
However, the statins like pravastatin, rosuvastatin and pitavastatin are not substrates of CYP enzymes and
hence the concomitant use of CYP inhibitors or inducers does not affect them. Almost all the statins are the substrates
of OATP1B1 transporter, and the co-prescription of inhibitors of OATP1B1 elevates the plasma concentrations
and muscle toxicity of statins.

Conclusion:

Understanding the interacting potential of each statin will enable the prescribers, pharmacists, and
other health care professionals to use statins effectively without compromising patient safety.

Authors: Thishya Kalluri , Sreenu Boddupally , Raju Sree B. , Kutala Vijay Kumar
Published: January 2021

Background:

Graft acceptance against immunity is one of the major challenges in solid organ transplant.
Immunosuppressive medications have effectively improved the post-transplantation outcome however, it
has its own limitations. Genetic polymorphisms in drug-metabolizing enzymes have been identified as the potential
targets in developing a pharmacogenetic strategy, to individualize drug dose and also in preventing the
adverse events.

Objective:

The rationale of the study was to explore polymorphisms in tacrolimus and mycophenolate
metabolic pathways that influence the adverse clinical outcomes in renal transplant recipients.

Methods:

A total of 255 renal transplant recipients were analyzed for the pharmacogenetic determinants of
tacrolimus (CYP3A5*3 ABCB1 1236 T>C ABCB1 2677 G>A/T ABCB1 3435 T>C) and mycophenolate
(UGT1A8*3 UGT1A9 IMPDH I IMPDH II c.787C>T ABCC2 -24 C>T and c.3972C>T) using Sanger sequencing.

Results:

Acute rejection (AR) was observed in 5.88% of the transplant recipients whereas acute tubular necrosis
(ATNs) was observed in 7.45% of the patients within early stage of the maintenance phase. Infections such
as urinary tract infection (UTI) and cytomegalovirus (CMV) infection were observed in 11.37% and 12.16% of
the patients. The AUC of mycophenolate was significantly higher in patients with increased risk for infections.
ABCC2 -24 C>T c.3972C>T polymorphisms and ABCB1 3435 C-allele were associated with reduced risk for
infections. ABCC2 rs3740066 was associated with 2.06-fold all-cause mortality risk. CYP3A5 AG- and
UGT1A9-440 CC-genotypes showed increased risk and ABCC 3972C>T CC-genotype showed protection
against adverse events.

Conclusion:

Genetic variants in tacrolimus and mycophenolate metabolic pathways were found to influence
the morbidity and mortality in renal transplant recipients.
GSK-3 Inhibitors: A New Class of Drugs for Alzheimer’s Disease Treatment
Authors: Pal Dilipkumar , Mukherjee Souvik , Song In-Ho , Nimse Satish B.
Published: January 2021

Alzheimer’s disease (AD), a chronic neurodegenerative disease, is the most common
form of dementia that causes cognitive function impairment, including memory, thinking, and behavioral
changes that ultimately lead to death. The overactivation of GSK-3, an enzyme from the
proline/serine Ki
NS family, has been associated with hyper-phosphorylation of tau proteins. The self-
-assembly of hyper-phosphorylated tau proteins to form tangles of straight and helical filaments is
known to be involved in AD. Therefore, GSK-3 has been considered a potential target of novel
drug discovery for AD treatment. Research on the development of GSK-3 inhibitors has received
enormous attention from the vast scientific community because they are targeted for AD and other
diseases, including type 2 diabetes, cancers, stroke, Parkinson’s disease and bipolar disorder. Various
drugs of both synthetic and natural origins have been designed to inhibit GSK-3 activity. However,
there is a need to develop novel drug candidates that can selectively inhibit GSK-3. Hence,
this review summarizes the potential of GSK-3 inhibitors for AD therapy and discusses the structure-
activity relationship of current drug molecules and the potential problems associated with
them.
Identifying New Pathways and Targets for Wound Healing and Therapeutics from Natural Sources
Authors: Feng Xinchi , Hao Jinsong
Published: January 2021

Chronic wounds remain a significant public problem and the development of wound
treatments has been a research focus for the past few decades. Despite advances in the products derived
from endogenous substances involved in a wound healing process (e.g., growth factors, stem
cells, and extracellular matrix), effective and safe wound therapeutics are still limited. There is an
unmet need to develop new therapeutics. Various new pathways and targets have been identified
and could become a molecular target in designing novel wound agents. Importantly, many existing
drugs that target these newly identified pathways could be repositioned for wound therapy, which
will facilitate fast translation of research findings to clinical applications. This review discusses the
newly identified pathways/targets and their potential uses in the development of wound therapeutics.
Some herbs and amphibian skins have been traditionally used for wound repairs and their active
ingredients have been found to act in these new pathways. Hence, screening these natural products
for novel wound therapeutics remains a viable approach. The outcomes of wound care using
natural wound therapeutics could be improved if we can better understand their cellular and molecular
mechanisms and fabricate them in appropriate formulations, such as using novel wound dressings
and nano-engineered materials. Therefore, we also provide an update on the advances in
wound therapeutics from natural sources. Overall, this review offers new insights into novel wound
therapeutics.
Improved Lipid Target Level Attainment in Patients with Peripheral Artery Disease
Authors: Dopheide Jörn F. , Adam Luise , Wiedmer Sebastian , Kaspar Mathias , Silbernagel Günther , Baumgartner Iris , Drexel Heinz
Published: January 2021

Background:

Patients with peripheral artery disease (PAD) fall under the category of a
very high cardiovascular risk. Although consequent lipid-lowering therapy (LLT) is advised, only
sparse data on attained target level in PAD exists.

Objectives:

We aimed to analyse contemporary guideline recommendations for LLT in symptomatic PAD patients.

Methods:

A monocentric, prospective, observational study involving 200 symptomatic PAD patients
was conducted. Guideline target level attainment and LLT were analysed between 2017 and
2019.

Results:

Overall, 78.5% of the patients were on statin therapy, mainly of high intensity, with atorvastatin
in 50% and rosuvastatin in 33% of the cases. The average statin dosage adjusted for simvastatin
was 55 mg/d. Low density lipoprotein-cholesterol (LDL-C) was <1.8 mmol/L in 53% and
<1.4 mmol/L in 34% of the cases. Mean LDL-C levels were at 1.85 ± 0.88 mmol/L. We observed
no difference in the treatment and the target level attainment of patients with a stable PAD (intermittent
claudication) or chronic critical PAD. However, patients with ≥ 1 vascular region affected
(i.e., coronary and/or cerebrovascular) were treated more intensively and had lower LDL-C levels
than patients with PAD alone.

Conclusion:

It appears that there are more awareness and improvement of previously documented
undertreatment of LDL-C levels in symptomatic PAD patients. Although statin treatment is initiated
in the majority of patients, our findings call for a continuously intensified LLT in symptomatic
PAD patients.
The Hidden Impact of COVID-19 on Sexual and Reproductive Health and Rights of Women in India
Authors: Sharmila Vijayan , Babu Thirunavukkarasu Arun
Published: January 2021

Coronavirus (COVID-19) outbreak was first reported in China in December 2019, and
the World Health Organization declared the outbreak as a pandemic on March 11, 2020. The
number of confirmed cases has risen alarmingly in most countries across all continents over the past
few months. The current COVID-19 pandemic has had an immense impact on sexual and
reproductive health and rights (SRHR) with disruptions in the regular provision of Sexual and
Reproductive Health (SRH) services such as maternal care, safe abortion services, contraception,
prevention and the treatment of HIV/AIDS and other sexually transmitted diseases. Other aspects
that merit attention include a probable increase in domestic violence, sexual abuse, and the effects
of the stigma associated with coronavirus infection on SRH clients and health care providers.
Furthermore, as the coronavirus infection is relatively new, only minimal data is available to
understand the impact of this disease on SRH, including coronavirus infection complicating
pregnancies, and in people with STI/HIV-related immunosuppression. There is a serious necessity
for the medical fraternity to generate psycho-social and clinico-epidemiological correlations
between coronavirus disease and SRHR outcomes. The article reviews the hidden impact of
coronavirus pandemic on sexual and reproductive health and rights of women, particularly in India.
Evaluation of the Behavioural, Antioxidative and Histomorphological Effects of Folic Acid-supplemented Diet in Dexamethasone-induced Depression in Mice
Authors: Falade Joshua , Onaolapo Adejoke Y. , Onaolapo Olakunle J.
Published: January 2021

Background:

The effect of folic acid in mitigating depression has remained pivotal in
research.

Objectives:

To determine the effects of folate supplementation on neurobehaviour oxidative stress
and cerebral cortex histomorphology in the dexamethasone mouse model of depression.

Methodology:

Male mice were assigned to six groups (A-F) of 10 mice each. Animals in groups A and
D were fed a standard diet, while those in B and E were fed folic acid supplemented diet (25
mg/kg of feed), while C and F were fed folate supplemented diet at 50 mg/kg of feed for 8 weeks.
At the beginning of the sixth 6th week, mice in groups A-C were administered distilled water,
while animals in groups D-F were administered dexamethasone (DEX) at 4 mg/kg body weight by
gavage. Open-field, forced swim, and tail-suspension tests were conducted at the end of the experimental
period, following which animals were euthanised and blood was taken for the estimation
of Malondialdehyde (MDA), reduced Glutathione, Glutathione Peroxidase, Catalase activity, and
Superoxide Dismutase. Sections of the cerebral cortex were prepared for histological examination.

Results:

Folic acid supplementation increased body weight, locomotor, rearing and self-grooming
behaviours, and decreased immobility time in the tail suspension and forced swim tests. There was
also a reduction of lipid peroxidation and an increase in the antioxidant status. Folic acid supplementation
was also found to be protective against the development of dexamethasone-induced
changes in body weight, open-field behaviours, behavioural despair, oxidative stress and cerebrocortical
morphology.

Conclusion:

Folic-acid supplementation improves the behavioral, some antioxidant, and cerebral
morphological parameters.

Authors: Mesbahzadeh Behzad , Salarjavan Hossein , Samarghandian Saeed , Farkhondeh Tahereh
Published: January 2021

Background:

Age-dependent toxic effects of organophosphorus pesticides (OPs) have
not been fully understood. The current study aimed to investigate the cardiotoxic damage of chlorpyrifos
(CPF) by evaluating oxidative modifications in young (2-month old), middle-aged (10-
month old), and aged (20-month old) rats.

Objective:

Five mg/kg of CPF was administered orally for 45 days to young, middle-aged, and
aged male Wistar rats. In the end, animals were anesthetized and the heart of each rat was dissected
for biochemical assay.

Methods:

Malondialdehyde (MDA), nitric oxide (NO), glutathione (GSH), total antioxidant capacity
(TAC), and superoxide dismutase (SOD) were assessed in the cardiac tissue of rats.

Results:

The results indicated an increase in the levels of MDA and NO, and also a decline in the
levels of GSH and TAC as well as a decrease in the SOD activity in the heart of aged rats compared
with young rats. CPF administration deteriorated these changes in the heart of exposed rats
compared with the age-matched controls. Additionally, these oxidative modifications were more severe
in aged rats versus other age.

Conclusion:

In conclusion, advancing age may increase oxidative changes in the heart of animals
exposed to CPF. It is suggested that aging can affect cardiac toxicity induced by OPs.
Theoretical Analysis of Single-Stage and Multi-Stage Monod Model of Landfill Degradation Through Mathematical Modelling
Authors: Murali Kirthiga , Solayappan Balamurugan , James Visuvasam , Lakshmanan Rajendran , Abukhaled Marwan
Published: January 2021

Background:

Preventing substantial environmental hazards caused by noxious gases and solutes
from sanitary landfills necessitates adequate regulations that require knowledge of the underlying
mechanisms involved and the effect of various strategies. Mathematical models have been used to understand
the development of landfill gas based on sequential biological growth and certain simple chemical
and physical processes.

Methods:

The single-stage and multi-stage Monod landfill degradation model is based on a coupled system
of rate equations containing a nonlinear term related to Michaelis- Menten kinetics of the enzymatic
reaction. In this communication, an approximate analytical solution of the nonlinear differential equations
is solved using a new approach of the homotopy perturbation method.

Results:

Substrate and biomass concentrations for the single-stage Monod landfill degradation model as
well as biomass, solid, aqueous, acetic, and gases for the multi-stage model are derived for all possible
values of parameters. Theoretical evaluations of the kinetic parameters such as the constant of Michaelis-
Menten, mass-specific growth rate, half-saturation, and the death rate are reported.

Conclusion:

The accuracy of the proposed analytical expressions is validated by direct comparison with
numerical simulations generated by MATLAB. A sensitivity analysis is presented to report the effect of
all parameters on the governing model and the time required to reach the steady-state. The obtained analytical
results are expected to contribute to a better understanding of the model and the effect of parameters
and hence a better designing of experiments.

Authors: Qazi Sahar , Sheikh Kayenat , Faheem Mo , Khan Arshad , Raza Khalid
Published: January 2021

Background:

Coronavirus disease 2019 (COVID-19) outbreak has created an emergency globally, and social
distancing and isolation is the only solution to prevent its spread. Several countries have announced full lockdown to tackle
this pandemic. The coronavirus family is inclusive of pathogens of both – animal species and humans, encapsulating the
isolated severe acute respiratory syndrome coronavirus (SARS-CoV). Researchers round the globe have been dexterously
working to decode this lethal virus. Many mathematical frameworks have also been depicted which have helped to understand
the dynamics of the COVID-19.

Methods:

This systematic review highlights the virus genomic composition, preliminary phylogenetic analysis, pathogenesis,
symptomatology, diagnosis, and prognosis along with mathematical models of disease transmission and dynamics.

Results:

Our preliminary phylogenetic analysis of the novel coronavirus sequence discerns that although shares its lineage
with SARS, BAT-CoV, Beta-BAT-SARS,however, this protein is highly dissimilar to its ancestors. The widely prominent
amino acid residues found in the protein are alanine (ALA), aspartic acid (ASP), phenylalanine (PHE), leucine (LEU), aspartic
acid (ASP), threonine (THR), valine (VAL), tyrosine (TYR) and asparagine (ASN) that are responsible for its replication
process.

Conclusion:

Research on coronaviruses continues towards developing a strong understanding of the rapidly evolving viral
replication and its transmission between individuals.

This study aims to review the implementation of the management of culture and environment of madrasah and the challenges faced, especially the private Madrasah at Gorontalo. The method used in this study is a naturalistic-qualitative study. The data were collected through observation, interview, and documentation. The findings obtained showed that the culture and environment at the private Madrasah Ibtidaiyah at Gorontalo were various in physical culture and behavioural culture. The physical culture can be seen from the physical appearance of madrasah which has different characteristics. The form of physical culture involved can be seen from the facilities, school building with fence, motto, and writing in the wall which support the development of expected culture. The behavioural culture can be seen from religious culture, discipline culture, and the implementation of the rules, achievement and competition culture, reading and clean culture. The implementation of the management of culture and environment of madrasah is in line with the vision, mission, and the goals of the school realized in the form of programs regarding the creation of culture and environment of madrasah by improving the participation of all people in madrasah in order to optimize the facilities which support cultural values that become the priority of each private Madrasah Ibtidaiyah in Gorontalo. In order to solve the problems, the awareness and commitment of people in madrasah are totally required especially in the fixing of the learning system and the enforcement of disciplines, which cultural values are important and unimportant. Besides that, the harmonious cooperation among all people in madrasah is essentially needed in managing the culture and environment of madrasah to elevate the competitiveness.

Reading is one aspect of language skills that affects student success in understanding various learning materials. Most students are already able to read, but not all students have good reading skill. Therefore, research related to reading skill still really needs to be done to influence students so they prefer reading activities, especially when learning in schools is less effective because of the corona 19 virus. Thus, students are expected to have positive activities when they learn from home like total reading activity. This study aims to measure the total reading skill of fifth-grade students through the Reading Questioning and Answering model. The research method used an experimental method with a pretest-posttest control group design. The research sample was the fifth-grade students who were randomly selected. This research was carried out with a home visit activity and was conducted online. The data were collected using a reading speed test and a reading comprehension test, while the data analysis used inference statistics. The results showed that the reading speed of the experimental class students was higher than the control class students. Subsequently, the reading comprehension skill of the experimental class students was higher than the control class students. Based on the research findings, the researcher concluded that the RQA Model affects the total reading skill of fifth-grade students

The purpose of this study is to describe the challenges and problems that occur in the development of learning media to improve critical thinking skills and character. This study examines how the challenges of teachers in developing learning media to improve students' critical thinking skills and character. The method was in the form of qualitative data (phenomenology). Data were collected by conducting interviews and observations on nine teachers from 3 public elementary schools in Sleman Regency, Yogyakarta, Indonesia. Based on research, it conducted that students' critical thinking skills and character will increase if the teacher can solve or face challenges in developing existing learning media.
Trajetórias subjetivas na experiência de formação
Authors: Tavares Carla
Published: January 2021

Abordando a formação docente por meio da divisão subjetiva, que impede a integralização de conhecimentos ou a totalização de toda e qualquer prática educativa, este artigo discute os resultados de uma pesquisa-intervenção de orientação psicanalítica com professores pré-serviço e em serviço, apoiando-se na articulação entre relação com o saber, experiência e transmissão, conforme concebidas no campo da Psicanálise e Educação. Por meio da oferta da palavra aos participantes em diferentes formatos, a pesquisa propiciou momentos de suspensão de certezas subjetivas por meio de intervenções e pontuações, objetivando permitir aos professores uma (re)apropriação da posição docente. A análise do corpus contemplou os movimentos subjetivos nessa direção, por meio do que denominei relatos de experiência. Por meio da narrativização das intervenções e de seus efeitos sobre os participantes, os relatos cartografaram os pontos em torno dos quais indiciou-se a construção de um saber particular sobre a docência e a inscrição no sujeito de algo da ordem de uma transmissão. Configurou-se, assim, a relação entre espaços de fala-escuta e a instauração da experiência como desencadeadores de trajetórias formativas marcadas peloinvestimento subjetivo e, portanto, marcadas por uma significativa relação com o saber.

No presente artigo, apresentam-se os resultados finais de uma pesquisa para a validação do instrumento Acompanhamento Psicanalítico de Crianças em Escolas, Grupos e Instituições (APEGI),1 bem como os eixos teóricos que sustentaram a sua construção. O APEGI é um instrumento que tem como base a teoria psicanalítica e busca proceder a uma leitura do processo de constituição subjetiva articulado ao desenvolvimento da criança. Neste artigo, descreve-se a segunda etapa da pesquisa, que ocorreu no período de abril ajunho de 2019, no qual foram aplicados 37 APEGIs em uma Escola Municipal de Educação Infantil de São Paulo. Cada aplicação foi realizada por uma dupla de pesquisadores, cujas aplicações foram confrontadas para depois ser gerada uma terceira síntese, consensual. A expectativa de validação confirmou-se, e o APEGI pode ser considerado um instrumento validado por meio de testes de validade convergente entre avaliadores e da consistência interna do instrumento. O instrumento APEGI propõe uma sistematização do conhecimento psicanalítico adquirido em mais de cem anos de prática clínica com crianças, fazendo do estudo de caso – método psicanalítico por excelência – um possível instrumentode uso em pesquisas científicas.
Reflexões sobre a “epidemia” de depressão em adolescentes e jovens adultos à luz da relação entre a psicanálise e a política
Authors: Legnani Viviane , Almeida Sandra Francesca
Published: January 2021

O artigo tem por objetivo refletir sobre os impactos de um dos eixos da
neurocultura, que é a medicalização de adolescentes e jovens adultos. Discute
criticamente o diagnóstico médico de Transtorno Depressivo, à luz da relação
entre a psicanálise e a política, e discorre sobre a problemática da depressão
no contemporâneo como um sintoma social. Apresenta uma vinheta clínica
para ilustrar essa discussão e conclui destacando a importância de um
reposicionamento discursivo da escola por meio de processos de subjetivação
política em face da lógica adaptativa neoliberal, amplamente arraigada nessas
instituições.

O presente artigo apura a análise dos resultados da pesquisa Dispositivos de formação docente que consideram a subjetividade. A metodologia usada napesquisa foi o registro escrito de professores/as psicanalistas a partir de duas questões acerca da implicação docente e dos métodos usados na formaçãovisando os impactos na subjetividade docente. Como resultado, apuramos que a conduta clínica implicada e a escuta qualificada de docentes em situações de queixa e mal-estar se configuram como importantes dispositivos a serem transmitidos na formação, reiterando a ineficácia de modelos prescritivos deformação de professores/as que se baseiam no ensino de técnicas e informações acerca de como o/a professor/a deve ensinar e trabalhar com seu aluno.Reafirma-se assim a necessidade de tempo para a elaboração precisa das experiências cotidianas para que estas possam de fato atravessar e marcar osujeito.

The spectral and amplitude-time characteristics of the emission of polymethyl methacrylate upon excitation by electron beams with electron energies up to 300 and 450 keV are studied. Vavilov-Cherenkov radiation and cathodoluminescence pulses were recorded with a subnanosecond time resolution. It is shown that the intensity of pulsed cathodoluminescence radiation in the visible and near ultraviolet spectral regions at electron energies of hundreds of keV exceeds the intensity of Vavilov-Cherenkov radiation.
