Authors: Tlish M. M. , Shavilova M. E. , Boyko N. A. , Romanova G. V.
Published: September 2024

At the present stage, there is an increase in the prevalence of psychodermatological disorders, while this pathology has a pronounced negative impact on the quality of life of patients. The observed bidirectional relationship between psychological well-being and skin health is being actively studied. Skin lesions can be caused by primary psychiatric diseases or provoke their appearance. The clinical symptoms of autodestructive dermatoses can imitate parasitic infections and pyoderma, skin tuberculosis, granulomatous and allergic diseases, vasculitis, and lymphomas. In this regard, patients initially seek medical help from doctors of various profiles, which, in the absence of proper awareness of specialists, often lengthens the diagnostic search, leads to progression of the disease and a deterioration in the quality of life of patients. Increasing awareness of psychodermatological comorbidity among primary care physicians is important to reduce the time required to make a correct diagnosis and timely referral of patients to a psychiatrist. The article provides an analysis of our own clinical observations of patients with psychodermatological pathology, for whom more than a year passed from the initial visit to the doctor to verification of the diagnosis. Late diagnosis was accompanied by an increase in symptoms with the formation of pronounced destructive skin lesions. The diagnostic search was also hampered by the significant similarity of the clinical picture with other diseases that have skin symptoms. When analyzing the presented clinical cases, attention is focused on the need for a thorough differential diagnostic search, an analysis of the characteristics of the anamnesis and characteristic symptoms of the skin process in psychodermatological pathology is provided. The importance of an integrated approach to patient management with the participation of specialists from both psychiatric and dermatological profiles was noted.

Published: September 2024

Introduction. Atrophic scars may be associated with significant psychological stress and a substantial negative impact on quality of life. Despite the great relevance of the atrophic scars therapy, existing treatment methods do not always provide their complete elimination.

Aim. To study the efficacy of combined therapy of atrophic scars with radiofrequency microneedling (RF-MN), subcision and hyaluronic acid filler injection.

Materials and methods. Ten female patients aged 28–44 years with a clinical diagnosis of atrophic scars were randomly assigned to two groups. Group 1 received RF-MN alone, while Group 2 received a combination treatment comprising RF-MN, subcision, and hyaluronic acid injections. Clinical effectiveness was assessed using the Goodman-Baron scar rating scale and the Global Aesthetic Improvement Scale (GAIS). Ultrasound was used to determine the changes in dermal thickness. The volume of depressions and skin texture were measured using the Antera 3D®. The safety of the treatment was evaluated by recording adverse events.

Results. The combined method demonstrated superior efficacy compared to RF-MN alone in the majority of efficacy parameters. In Group 2, a statistically significant reduction in Goodman-Baron scale was observed in 100% of patients (p = 0.026). 3D measurements of the face demonstrated a more pronounced improvement in skin texture in Group 2 relative to Group 1. Statistically significant changes (p = 0.027) in the Face-Q scale were exclusively observed in the group that received the combined treatment. Ultrasonic imaging demonstrated a restoration of dermal thickness following treatment. No serious adverse events were observed. Expected local adverse events (pain, erythema, swelling, and bruising) were mild and resolved spontaneously within 1–7 days.

Conclusion. The combined treatment with RF-MN followed by subcision and hyaluronic acid filler injections demonstrated its efficacy in patients with atrophic scars.
Pode a igualdade de condições para o acesso e permanência no ensino superior contribuir para fortalecer o direito fundamental à própria democracia?
Authors: Montes Netto Carlos Eduardo , Martinez Vinício Carrilho
Published: September 2024

A presente pesquisa pretende investigar o direito fundamental à igualdade de condições para o acesso e permanência no ensino superior, sob a perspectiva do direito fundamental à própria democracia. Sob os métodos de revisão de literatura, dedutivo e qualitativo, o objetivo principal do trabalho é analisar se o direito fundamental à igualdade de condições para o acesso e permanência no ensino superior pode contribuir e, em caso positivo, de que forma, para fortalecer a formação humanística dos alunos, que representa um dos pilares da missão das universidades públicas e particulares, e assegurar o próprio direito fundamental à democracia, que é mais do que uma “obrigação eleitoral” periódica, pois não se contemplam suas regras societais somente a cada dois/quatro anos. Mais do que o próprio diálogo – que é também o esforço que Paulo Freire, denota ao sentido de revolução (transformação radical em práxis) – uma vez que não é possível dialogar com antagônicos, por exemplo, os que se validam pela regra da exclusão absoluta, ou seja, não é possível tolerar (democraticamente) a intolerância negativa. Ao final, concluiu-se que o direito o direito fundamental à igualdade de condições para o acesso e permanência no ensino superior possui amplo fundamento constitucional e legal, com potencial para fortalecer a democracia defensiva, ligada à luta de defesa dos direitos mais básicos, bem como incrementar uma verdadeira democracia propositiva, promovendo resiliência em face de possíveis retrocessos presentes e futuros, sendo essencial ao exercício da própria democracia em si, enquanto direito humano e fundamental.
Racismo e o emprego de novas tecnologias pelo estado no âmbito da segurança pública
Authors: De Matos Gilson Ely Chaves , De Lemos Marcelo Augusto Rodrigues , Silva Clara Virgínia de Oliveira
Published: September 2024

O racismo perpassa por toda a história do Brasil, revelando-se como instrumento pelo Estado no exercício da biopolítica, de modo a estar incrustrada na sociedade e em todas as estruturas do próprio Estado Brasileiro, inclusive, nas instituições policiais que terminam por atuar seletivamente contra a população negra, o que produz verdadeira necropolítica. Neste contexto se revela a concepção do racismo multidimensional de Jessé Souza, a qual é delineada por um conjunto de ações opressivas que humilham os negros no âmbito da sociedade, sob o manto de diversos disfarces a considerar o contexto social, incluindo-se aí a ação repressivo-punitiva do Estado. A par disso, a constante evolução tecnológica tem promovido significativo avanço das tecnologias digitais, em especial pelo emprego da inteligência artificial (IA), do big data, da Internet das Coisas (IoT), dentre outras que, na área da segurança pública, mostra-se promissora com o desenvolvimento de sistemas preditivos que permitem uma alocação de recursos mais eficaz na prevenção do crime. Buscou-se neste artigo responder acerca da importância da transparência e controle do Estado policial na utilização do policiamento preditivo em razão do viés discriminatório racial. Para tanto, foi realizado o levantamento de estudos existentes acerca do emprego das novas tecnologias digitais em sistemas de policiamento preditivo. Como resultado observou-se o grave risco do viés discriminatório no emprego da IA em sistemas de policiamento preditivo. Desta forma, foi confirmada a necessidade de mecanismos de transparência, responsabilidade e equidade no emprego da IA de modo a conter abusos e práticas discriminatórias. Neste artigo empregou-se uma abordagem qualitativa mediante a técnica de revisão bibliográfica através do método hipotético-dedutivo.
“O céu é o limite?”: Drones na segurança pública, novas dimensões de vigilância e impactos nos direitos fundamentais da personalidade
Authors: Alécio Débora , De Ávila Gustavo Noronha
Published: September 2024

A presente pesquisa visa analisar se a legislação vigente trata do emprego de drones voltados para a utilização na segurança pública, e se este uso indiscriminado pode ferir a privacidade e intimidade dos cidadãos enquanto direitos fundamentais da personalidade. Assim, busca-se desvendar a utilização desta ferramenta nas mãos do poder estatal, investigando as regulamentações existentes e avaliar o impacto dessas tecnologias nos direitos individuais. Procurou-se demonstrar que a vida privada se encontra ameaçada pelo uso dessa tecnologia no dia-a-dia das polícias em suas atividades de prevenção de crimes em nome de um “bem maior”, que é a coletividade. Para o êxito desta foi utilizada a metodologia hipotético-dedutiva por meio do método teórico-bibliográfico, com coletas de dados realizados em sites de busca acadêmica, bibliotecas, legislações vigentes e revistas científicas que abordam a temática. Os resultados obtidos circulam na violação dos direitos da personalidade diante da privacidade e intimidade, a qual é ultrajada com o uso indiscriminado de tecnologias de grande alcance e de difícil limitação de um filtro de vigilância, na qual em nome da coletividade fere-se a esfera mais individual da vida humana.

Authors: Peixoto Arêas da Silva Roberta , Abreu Alice Rangel de Paiva , Santana Ademir Eeugênio de , Barbosa Marcia Cristina Bernardes , Nobre Carlos
Published: September 2024

Women are underrepresented in science and their participation decreases as their career progresses; an international phenomenon clearly displayed in a scissors graph. This decrease is usually attributed to maternity, a lower number of publications, and less ability to receive grants. Here we present a comprehensive study of the Brazilian science and technology system, covering 8,877,626 people, and analyzing the participation of women from the undergraduate to ministerial levels. The study used different data-bases to develop relevant indicators of the participation of women, some of them over a period of 15 years. Our results suggest that the decrease of women as their career advances is due to a combination of barriers that need to be faced and eliminated to promote equity for better science.

Authors: Abbas Eman M. H. , Sabour Rehab , Alsaiari Norah A. , Medrasi Hanadi Y. , Kassem Asmaa F. , Farghaly Thoraya A.
Published: September 2024

Background and Objective:

Breast cancer is the most common form of cancer
in women and is the leading cause of cancer-related deaths among women globally.
In this study, we aimed to synthesize a series of tropane derivatives to investigate their
Hsp90 inhibitory activity as well as their cytotoxic impact on breast cancer cells (MCF-
7 and MDA-MB-231).

Methods:

Novel fused-tropane derivatives were created and produced as inhibitors of
Hsp90, taking inspiration from XL888, a tropane medication used for treating cancer.
The target compounds were screened in vitro to determine their ability to inhibit the activity
of Hsp90.

Results:

All tropane derivatives displayed a good submicromolar inhibition of Hsp90
with IC50 values ranging from 52.64 to 76.05 nM, relative to XL888 reference medication
(IC50 = 27.78 nM). Among all the compounds examined, tropane derivative 5 exhibited
the highest level of Hsp90 inhibitory action, with an IC50 value of 52.64 nM. Furthermore,
the cytotoxic activity of all compounds was evaluated against two breast cancer
cell lines, namely MCF-7 and MDA-MB-231. Tropane derivative 5 exhibited greater
potency than doxorubicin against both cell lines. In addition, it demonstrated a safety
profile significantly superior to that of doxorubicin when tested on normal human cells
(WI-38 cells), thereby confirming its exceptional level of safety. The western blotting
analysis demonstrated a 2.4-fold reduction in Hsp90 expression in MCF-7 cells. Furthermore,
the molecular docking analysis has provided additional evidence for the capacity
of compound 5 to effectively bind with the target Hsp90 enzyme.

Conclusion:

We have succeeded in synthesizing novel tropane hybrids exhibiting significant
anti-Hsp90 action, similar to XL888 analogues.
Exploring the Arsenal of Novel Antifungal Drug Targets for Combating Fungal Infections
Authors: Joshi Pooja , Navale Archana , Shelke Ajay , Patel Muskan
Published: September 2024

Fungal infections contribute to over 1.5 million fatalities each year, with cutaneous
mycoses standing as prominent global infections. The spectrum of these mycoses varies widely,
encompassing enduring afflictions like ringworm, localized infections such as tinea capitis, recurrent
instances like vaginal candidiasis, and potentially fatal systemic infections impacting
multiple organ systems. The escalating recognition of the health and socioeconomic ramifications
associated with fungal pathogens underscores their importance in contemporary discourse.
On a global scale, projections indicate that over 300 million individuals experience significant
fungal infections annually, resulting in a mortality rate exceeding 1.5 million deaths per year.
Alarmingly, resistance to commonly used antifungal drugs was on the rise, with some reports
suggesting that over 10% of Candida bloodstream isolates worldwide were resistant to fluconazole,
a commonly prescribed antifungal medication. Therefore, there is an immediate need to
increase the accessibility of new antifungal medications while minimizing their costs and adverse
effects. Fungi, as heterotrophic organisms, acquire nutrients through absorption. Their
filamentous structure, composed of hyphae, facilitates efficient nutrient uptake by secreting enzymes
that break down complex organic matter into simpler compounds. These organisms exhibit
remarkable adaptability in responding to environmental cues, adjusting growth rates, and
altering morphological features. Fungi regulate their metabolism intricately, undergoing various
metabolic pathways for energy production and utilizing diverse substrates for respiration. Additionally,
they exhibit distinctive reproductive strategies, employing both sexual and asexual
modes of reproduction, contributing to their genetic diversity and resilience in diverse ecosystems.
We now have more information than ever on the origins of infection as well as the physiology
of fungi cells, giving us the chance to use it to produce new generations of antifungals.
This review includes various novel antifungal drug targets showing their possible effects via
different mechanisms aiming at vital functions like GPI synthesis, cell wall synthesis, hyphal
growth, and other essential pathways responsible for fungal growth.
Marine Drugs for Topical Nanoformulation and Cosmeceutical Applications
Authors: Sharma Anjali , Singh Abhishek , Srivastava Nimisha , Dan Deblina
Published: September 2024

Marine sources, such as phytoplankton and zooplankton from seas or oceans that correspond
to various marine ecosystems, are the sources of marine pharmaceuticals. These medications
have been utilized as active ingredients in cosmeceutical formulas to treat a range of skin
conditions. Cosmeceuticals, or cosmetic products with an active pharmaceutical ingredient that
imparts therapeutic efficacy or has benefits similar to those of medicine for skin health, are characterized
as cosmetics plus medicines. Algae, fungi, sea cucumbers, seaweed, corals, prawns, and
other marine organisms can all produce medicinal components that effectively treat wrinkles,
blemishes, aging, hyperpigmentation, and oxidation. Because these medications and sources are
natural, they have few or no negative effects on the skin. The skin is the site of action for the topical
distribution of marine medicines and cosmeceuticals to treat this condition. This study investigates
a viable nano-delivery method for marine medications in cosmetics, providing long-term
and practical means of improving skin health and treating dermatological issues. The focus of this
review is on marine medications, their chemical components, cosmeceutical usage, and the pathophysiology
of various dermatological conditions. Additionally, raw ingredients used as excipients
in cosmeceutical formulations can be sourced from marine species. Because of massive industrialization,
unsustainability has become a major research topic. Marine chemicals, on the other
hand, are highly eco-friendly and sustainable. A thorough analysis of the literature in this area
focuses on the effects of different marine chemicals on the skin, as well as on the physicochemical
parameters and post-formulation evaluations. As far as current research and prospects go, the
cosmetics and cosmeceuticals sector is a better fit for marine pharmaceuticals when treating skin
conditions.

Published: September 2024

Introduction:

The antioxidant fraction of Stevia rebaudiana has important
antidiabetic potential, is poorly soluble, and has low stability, which makes its applicability
difficult.

Materials and Methods:

In this study, Stevia's fraction was obtained, characterized by
Ultra-high-performance liquid chromatography coupled with mass spectrometry (UHPLCMS/
MS), and microencapsulated with maltodextrin (MDF), gum arabic (GAF), whey protein
+ maltodextrin (MDWF), and whey protein + gum arabic (GAWF). Then, the following
parameters were evaluated: stability and antioxidant capacity over 30 days, physicochemical
characteristics, preservation of bioactive compounds by digestion, and in vitro antidiabetic
activity.

Results and Discussion:

The microcapsule with gum arabic showed better microencapsulation
efficiency, while its version with maltodextrin provided increased solubility. Microencapsulation
reduced the humidity and water activity in the microcapsules, except for the microcapsules containing
gum arabic. The combination of maltodextrin and whey protein showed greater luminosity
and a whiter powder. The microcapsules with maltodextrin and its mixture with gum arabic
kept the phenolic compounds stable for 30 days. The microencapsulation with whey protein increased
the antioxidant activity after 15 days of the process and during in vitro digestion. All
samples showed 96% inhibition of the α-glucosidase enzyme, and only the microcapsule with
maltodextrin inhibited α-amylase (58%).

Conclusion:

This study showed paramount results so that Antioxidant Stevia Fraction (ASF) can
effectively be an adjuvant product to prevent and treat diabetes.

Published: September 2024

Aim: Doubled haploid technology was utilized to accelerate the development of maize lines with traits suitable for high planting density, enabling the identification of potential parental lines for hybrid development under these conditions. Methodology: Two F1 populations (PML-119 x PML-185 and PML-95 x PML-172) were used to generate doubled haploid lines, confirmed using polymorphic markers phi115 and umc1887. These lines were phenotypically evaluated under high density (60 cm x 15 cm) and normal density (60 cm x 20 cm) conditions. Results: Using doubled haploid technology, 67 lines were developed from two source populations with traits such as narrow leaf angle, moderate plant height, and sparse tassel for high planting density stress tolerance. Molecular marker screening confirmed the homozygosity of these lines. Agronomic evaluation under narrow plant-to-plant spacing (15 cm) identified eight potential donor lines amenable to high planting density stress, ready for use as parents in breeding high-density tolerant hybrids. Interpretation: Potential donor doubled haploid lines viz. DH2-4, DH2-8, DH2-9, DH2-11, DH2-14, DH2-15 derived from Population-3 X CIM2GTAIL P2 and DH2-4, DH2-23 derived from Population-9 X CIM2GTAIL P2 were identified for utilization as putative parents of hybrids suitable for planting under high planting density conditions.

Feasible or Fashionable? Investigating Organizational Adoptions of Social Impact Bonds
Authors:   , Munksgaard Mikkel
Published: September 2024

This project investigates how organizations adopt and use social impact bonds (SIBs). SIBs are new forms of management instruments (MIs) that combine payment-by-results contracting with social investments to increase the quality and effectiveness of welfare services. The project investigates the role of policy context in SIB adoption (paper 1), the different types of implementation determinants in SIBs (paper 2), and the process of SIB operationalization undertaken by organizations (paper 3 and 4). The project is based on two qualitative case studies, a literature review, and quantitative evaluation. It primarily draws on translation theory and argues that SIB adoption is catalyzed by continuous interactions between organizations, instruments, and institutions often resulting in substantial modifications of the SIB instrument. The project finds SIBs to be ambiguous and complex types of management instruments with some potential to improve welfare provision. Four possible trajectories for future SIB development are discussed. These include utilizing SIBs as 1) temporary projects to increase the evidence-base of welfare services, 2) policy experimentation tools directed as inspiration for new legislation, 3) traditional SIB models but with a larger scale to ensure cost-effectiveness, and 4) investment models to optimize philanthropic capital with a low return-on-investment.

Sosyal bilgiler öğretmen yetiştirme programlarını içerik açısından değerlendirmeyi amaçlayan çalışmalar incelendiğinde, bu çalışmaların ya YÖK'ün çerçeve programının betimsel bir değerlendirmesini sunduğu ya da eski programla veya başka bir referans kaynakla karşılaştırmalı bir inceleme sağladığı görülmektedir. Programların değerlendirilmesine yönelik yapılan çalışmalarda ise farklı paydaşların deneyim ve bakış açıları ele alınmaktadır. Ancak YÖK’ün üniversitelere verdiği program değişiklik yapma yetkilerini nasıl kullandıklarına dair araştırmaya rastlanmamıştır. Bu araştırma, yetki devri öncesinde YÖK tarafından üniversitelere programlarda değişiklik yapılması konusunda tanınan sınırlı serbestliğin nasıl uygulandığını, bu dönemde sosyal bilgiler öğretmenliği lisans programlarının içerik açısından nasıl yapılandırıldığını incelemeyi ve bu programlarla ilgili sorunları tespit etmeyi amaçlamaktadır. Betimsel tarama modelinde yürütülen araştırmanın çalışma evrenini 53 eğitim fakültesinin sosyal bilgiler öğretmenliği lisans programları oluşturmaktadır. Araştırmada veri toplama tekniği olarak doküman incelemesi kullanılmıştır. Araştırmanın sonuçlarına göre 19 üniversite YÖK (2007) çerçeve programındaki zorunlu dersleri hiçbir değişiklik yapmadan uygulamıştır. AKTS kredileri açısından ise üniversiteler arasında önemli farklılaşmalar mevcuttur. Üniversitelerin programlarına ekledikleri seçmeli ders sayıları 7 ile 57 arasında değişmektedir. Programlarda en çok sosyal bilimler alanıyla ilgili seçmeli dersler yer almakta, bunlar içerisinde ise en çok tarih ve coğrafya disiplinlerine ait dersler bulunmaktadır. Programlarda, derslerin uygun olmayan dönemlerde sunulması, tekrarlayan derslerin ya da içeriğin bulunması, zorunlu seçmeli uygulaması gibi sorunların varlığı tespit edilmiştir.

Рассмотрены проблемы определения биологической эффективности фунгицидов для защиты всходов дуба от мучнистой росы. Эта болезнь часто встречается в лесных питомниках при выращивании посадочного материала, а также в естественных лесах. В арсенале средств защиты дуба в питомниках от мучнистой росы в настоящее время нет ни одного разрешённого пестицида. В связи с этим особую значимость получают испытания современных фунгицидов, предоставляющие возможность на легитимных условиях применять средства защиты. При проведении таких испытаний очень важно как можно более объективно оценить биологическую эффективность этих пестицидов. С этой целью предложено несколько формул для оценки защитного действия фунгицидов и проверена возможность их применения.

The article discusses the issues of determining the biological effectiveness of fungicides to protect oak seedlings from powdery mildew. This disease is of great importance in nurseries when growing planting material, as well as in natural forests. Currently, there is not a single approved pesticide in the arsenal of oak protection products in nurseries from powdery mildew. Therefore, it is important to test modern fungicides in order to be able to use protective equipment on legitimate terms. When conducting such tests, it is important to evaluate the effectiveness of these pesticides as objectively as possible. In order to evaluate the results as objectively as possible, the possibility of using some formulas for this has been tested. The comparisons made it possible to choose one of the formulas that most objectively assesses the effects of the fungicide.
