ABSTRACT Emotional and behavioral problems in adolescents are critical issues that impact the well-being of individuals and society. The prevalence of mental disorders in adolescents globally reaches 10-20%. This study aims to identify emotional and behavioral problems of adolescents at SMPN 77 Central Jakarta using the Strengths and Difficulties Questionnaire (SDQ). The design of this study was cross-sectional with 264 respondents aged 11-17 years. Results showed the majority of respondents were in the “Normal” category. However, females were more likely to be in the abnormal category on emotional problems (33.1%) than males (13.9%), while males were more in the borderline category on behavioral problems (19.7%). These findings suggest the importance of early intervention to address emotional and behavioral problems in adolescents. Keywords: Adolescents, Emotion, Behavior, SDQ  ABSTRAK Masalah emosi dan perilaku pada remaja adalah isu kritis yang berdampak pada kesejahteraan individu dan masyarakat.

La política acuícola: ¿Instrumento para el desarrollo regional?
Authors: Rosales-Inzunza Sergio , Acevedo-Valerio Víctor Antonio
Published: February 2025

Cristalizar el vasto potencial acuícola de las regiones del país no es imposible, siempre y cuando se sigua el orden debido en cada una de las fases que conforma el dominio del paquete tecnológico de la especie a cultivar. Para el éxito acuícola no es suficiente contar con una base natural de recursos ni creer que su crecimiento depende de la cantidad de granjas incorporadas al cultivo. Más bien, trata de un proceso ordenado de acciones interdependientes y complementarias, cuyo punto de arranque exige el dominio en cautiverio del ciclo biológico de la especie a cultivar. Las acciones posteriores buscan que se transfiera al sector productivo, donde se desplegará su escalamiento a nivel industrial y su internacionalización.

Authors: Madero-Gómez Sergio Manuel
Published: February 2025

La crisis actual que está viviendo el mundo, iniciada en 2008, ha traído como consecuencia que muchas empresas hayan adoptado diversas estrategias para hacer frente a esa situación. Lo anterior nos ha llevado a realizar la presente investigación para conocer la relación que existe entre el ambiente laboral, las estrategias de austeridad y los criterios de excelencia. En una muestra de 525 personas se pudo identificar que la reducción de los presupuestos en las empresas fue la medida más señalada por los trabajadores para enfrentar la crisis económica (MD. 3.8629, SD. 1.20) , además se comprobó que las estrategias de austeridad usadas en las empresas sí tienen una percepción  negativa por parte del trabajador (posibilidad de perder su empleo o tener un futuro incierto) que de alguna manera tiene un impacto negativo en el ambiente laboral.
Method for Hyper Speed in Moving Body by Temperature Cooling, According to the Theory of New Axioms and Laws
Authors:   Bulgarian Academy of Sciences, Markova Valentina
Published: February 2025

In the present article, a method and technology for obtaining Hyper Speeds for a moving body in a fluid medium is
proposed. This is done by using the Theory of new Axioms and Laws that contains 2 new Axioms and 8 new Laws
(briefly called the new Theory). In the present development the author applies only 1 Axiom and 4 Laws are applied.
The new Theory is based on two types of motion - motion of an open longitudinal vortex and an open transverse
vortex. Each of them can be accelerating (with positive acceleration) or decelerating (with negative acceleration).
Thus, the new Theory is based on 4 (rather than 1) non-uniform motions with variable velocity and acceleration.
On this extended basis the new Theory explains the resistance and heating of surface with the appearance of open
decelerating transverse vortices. The decelerating motion is described by Law 5. It describes how the decelerating
motion generates decelerating transverse vortices that are hot waves.
The essence of the new method is to suck from out the decelerating hot vortices that are formed due to friction of
the moving body in a fluid environment. The suction is done by applying Law 6. It describes how the accelerating
movement sucks in transverse vortices.
The role of a decelerating transverse vortices are played role by the hot waves of hot vortices (due to the friction)
emitted by the surface of body toward the environment. The role of open accelerating vortex is played by a frozen
fluid that sucks and absorbs the warm from environment according Thermodynamic Theory.
Therefore the Theory of new Axioms and Laws intersects with the Theory of Classical Thermodynamics is Law 6.
That is why the application of Law 6 is modified according to the conditions. Accelerated sucking in is replaced by
a layer of the surface of the body with a very sharply reduced temperature. This part of body can be performed by
a longitudinal layer of body filled by special material (gel), pre- cooled and poured in the volume of layer. Thus,
suction due to accelerated movement is replaced by suction due to a difference in temperature by a special material.
Investigation of Orbital Controllability Conditions for Small Satellites Taking Into Account the Parameters of Electrostatic Engine
Authors:   St. Petersburg State University of Aerospace Instrumentation, St. Petersburg, Russia, V. Nebylov Alexander
Published: February 2025

The requirements for an electrostatic engine as an actuating element of a small satellite orbit correction system are
investigated. It is shown that the already developed engines are too large in size, weight and power consumption to
be installed on a nano-satellite even of the U10 format. It is recommended to focus on the construction of controlled
small satellites for a mass of 20-30 kg and the corresponding dimensions, similar to the already well-proven satellites
of the NorSat series.
The desire to build and launch a group of small satellites of the Cube-Sat format (Cubsat) with a controlled
configuration is used already two decades because of the well-formulated motivation and the real comparative
cheapness of implementation. But the development of this idea takes place mainly for orbitally unguided satellites
and without describing the features of their design.
This publication explains the methodology for choosing the size of the satellite and recommends increasing the
mass of the satellites under consideration to 30 kg, which will create conditions for placing a full set of electrostatic
engines on board with all the necessary attributes for their effective operation during the orbital relative correction
of the satellites in their formation.
A Review of Research Achievements and Their Applications on the Essence of Electron Spin
Authors:   Huanggang Normal University, Huanggang City, Hubei Province 438000, China, Tu Runsheng
Published: February 2025

A model of the electronic internal structure has been developed, revealing the specific movement mode of electrons outside the
nucleus. Building on this, the Bohr's planetary model of the hydrogen atom has been adapted into the Saturn model, suitable
for describing multi-center and multi-electron bound systems. It has been discovered that the mathematical formalism of Bohr's
old quantum theory and wave mechanics are compatible. A quantum chemistry method has been established to implement
this compatibility (where the Saturn model and wave mechanics can complement each other), using this method, the energy
eigenvalues of s electrons in atoms and the binding energies and bond lengths of four diatomic molecules such as hydrogen
molecules have been successfully calculated. This provides new insights into material structure theory. The aforementioned
compatibility could lead to the birth of local realism quantum mechanics.
Is the Evolution of Mankind and the Universe Solely a Physical Selfrunner?
Authors:   Argelander Institute for Astronomy, University of Bonn, Auf dem Huegel 71, 53121 Bonn (Germany), J. Fahr Hans
Published: February 2025

For many people of our present, thinking mankind it appears
already as a deep intellectual sin to aim at a physics-based natural,
purely scientific explanation of what happens all round in the huge
universe: it is in fact seen as the so-called "cosmologic sin"! This is
because such an arrogant attempt is directly ranked by most people
confronted with it as a clear disdivination of the holy creation of
the total world, identifyable with a revocation of any independence
and internal beauty of the cosmic creation. It is, as if already the
simple attempt to look for a physical explanation of the cosmic
evolution would convert the world into a manmade universe
and would represent a full dechantment of its gloriosity - rather
degrading the latter to a trivial mechanical clockwork. But is it
not just too marvelous, seen in a little bit alternative view, that the
human attempt of the rational interpretation of the manifest cosmic
world just represents a wonderful indication, that this universe - as
a completely transcendental being for the human consciousness -
talks to this human brain and thereby even installs in fact a tight,
valid and mutually supported interaction?
Research Progress on the Schrödinger Equation of Gravitational Potential Energy
Authors:   Huanggang Normal University, Huanggang City, Hubei Province 438000, China, Tu Runsheng
Published: February 2025

People believe that the Schrödinger equation cannot be used to describe macroscopic objects like the Earth, and Newtonian
mechanics cannot be used to describe microscopic systems. The old concept of the relationship between the existing laws of
quantum mechanics and classical mechanics undoubtedly has a serious impact on people's understanding of the natural world,
the development of physics theories, and the application of existing physics theories. The continuous development of physics
theory requires constant changes to some incorrect old concepts. The Schrödinger equation that can describe planetary motion
was successfully obtained by replacing the potential energy in the Hamiltonian operator from electromagnetic interaction
potential energy to gravitational interaction potential energy. If the distance between the sun and the earth is approximated
as a constant, the energy eigenvalues obtained by solving the Schrödinger equation for the Earth's revolution are completely
consistent with the results obtained directly using classical mechanics. The direct significance of establishing and applying
such equations is that they can simultaneously use classical mechanics and wave dynamics to describe all objects (no longer
limited by the mass of the objects), simplifying the calculation process of quantum mechanics. It has been proven that classical
mechanics and wave dynamics are compatible, and there is no insurmountable gap between them. This result has a huge
positive impact on the theoretical updates and applications of quantum mechanics.

Many medicinal plants are commonly used in traditional treatment of ulcer however, the dosages remain unclear. The
study examined the effects of Chromolaena odorata, Bryophyllum pinnatum and Talinium triangulare leaf extracts on
biochemical markers and ulcer parameters of ulcer-induced adult male wistar rats. Christmas bush and cathedral bells
leaves were harvested from Nsukka town, while water leaf was bought from Ogige market at Nsukka, Enugu State. They
leaves were processed into flour and marcerated in water for 48 hours to obtain extracts. Adult male Wistar rats (72)
were acclimatized and randomly assigned to groups. Ulcer was induced with indomethacin solution before treatment
commenced. Different doses of the extracts were administered orally for a period of 14 days. Biochemical analysis of
serum prostaglandin (PG), superoxide dismutase (SOD) and catalase (CAT) levels were conducted. Thereafter, the rats
were sacrificed and gastric volume, ulcer index and pH of the gastric juices determined using standard assay. Statistical
analysis was performed using IBM-SPSS version 23, with significance set at p<0.05. The extracts reduced PG levels
while increasing CAT and SOD levels. A significant difference (p<0.05) in PG levels was observed between baseline
and end-line values in groups induced without treatment and all treated groups. Significant difference (p<0.05) existed
between baseline and end-line values of catalase and SOD in all the treated groups. Significant (p<0.05) reduction
occurred in ulcer index values between induced without treatment and other rat groups. The leaf extracts have the
potential to ameliorate mucosal inflammation and gastric effect of indomethacin-induced ulcer.
Nietzsche and Montaigne: Dionysian Pessimism
Authors: O'Sullivan Timothy
Published: February 2025

Friedrich Nietzsche’s writings are replete with attacks on past philosophers— Socrates, Plato, Kant and Hegel: all these are subject to his censure. Even Arthur Schopenhauer, whose philosophy is of fundamental importance to Nietzsche and whom he greatly admired, is not immune from criticism: Schopenhauer’s philosophical pessimism is persistently mocked in Nietzsche’s later work. With this in mind, Nietzsche’s unswerving reverence for Michel de Montaigne appears all the more remarkable. Whenever Nietzsche mentions Montaigne in his writing, his comments reveal a profound
admiration. Considering Nietzsche’s esteem for Montaigne, one would expect to find
discussions of Montaigne’s Essays pervading his work; yet Nietzsche’s explicit engagement with Montaigne amounts to no more than a few remarks scattered
throughout his corpus. As a consequence, the impact of Montaigne’s thought on
Nietzsche has, hitherto, received scant scholarly attention. But the Essays exerted a profound effect on Nietzsche and the paucity of direct reference to Montaigne in his work belies a substantial implicit influence. The aim of my paper is to address this lacuna in the literature by making evident the importance of the Essays to the development of Nietzsche's philosophy. Nietzsche’s embrace of Montaigne in “Schopenhauer as Educator”, the third of his Untimely Meditations, marks a fundamental turning point in
his thought and is essential to understanding his mature philosophy. I argue that Montaigne is a key inspiration for Nietzsche as he begins to conceive of a counter ideal to Schopenhauerian pessimism—what he calls Dionysian pessimism.

Published: February 2025

Oxidative stress has profound effect on mitochondrial DNA (mtDNA) and could cause mitochondrial dysfunction if remains unrepaired. Here, we showed that 20 μM H2O2 stress over 96 hours could induce mtDNA deletion in Danio rerio model. Although the fishes did well upon such a challenge with an LC50 value of 257.494 ± 19.434 μM, deletion in their egg mtDNA was observed but degradation was observed for the brain mtDNA. The water quality was not altered with the addition of 20 μM H2O2. We have successfully identified a deleted region of the Danio rerio mtDNA. The estimated size of the deletion was 7124 bp and was observed in both egg and brain mtDNA. We deduced that such deletion could have occurred from a recombination between an inverted repeat pair of Danio rerio mtDNA, and a fusion protein composed of cytochrome c oxidase II and cytochrome b could be generated upon such deletion. Such fusion protein could lead to mitochondrial dysfunction further.

Comparative genomics and phylogenetic analysis of complete chloroplast genome of Scaphium scaphigerum (WALL. EX G. DON) G. PLANCH
Authors: Ahmed Sheikh Sunzid , Rahman M Oliur
Published: February 2025

Scaphium scaphigerum (Wall. ex G. Don) G. Planch. is a threatened medicinal tree of Bangladesh, belonging to the family Malvaceae. This study unveiled the first chloroplast genome of the species, spanning 160,927 bp with a GC content of 36.89%. The plastome exhibited the typical orbicular quadripartite structure of angiosperms, consisting of a pair of inverted repeat regions (25502 bp), isolated by a large-single copy region (90012 bp) and a small single-copy region (19911 bp). The plastome harbored 128 genes in total, including 85 protein-coding genes, 35 tRNAs and 8 rRNAs. Comparative analyses with several other species revealed high synteny and lack of major rearrangements, along with similar gene order and GC content. The plastome contained 115 SSRs, predominantly comprising mononucleotides (78). Among the longer repeats, palindromic sequences were the most frequent (22). Nucleotide diversity analysis identified two hypervariable sites (ycf1 and ndhI) in the small single-copy region, which will facilitate DNA barcoding endeavors. Phylogenetic analysis showed close alliance of S. scaphigerum within Sterculioideae, with strong bootstrap support. Molecular dating suggested that the species originated during the Lutetian age (48.23 MYA) of the Cenozoic era.

Published: February 2025

The coastal areas of Bangladesh are enriched with migratory avian species but the actual status of birds was unknown, particularly in the south-central coastal region of the country. A yearlong (June 2023 to May 2024) direct field observation-based study was conducted to unfold the present status of the migratory avifauna in three protected areas (Kuakata National Park, Tangragiri Wildlife Sanctuary, and Sonarchar Wildlife Sanctuary). In this study, a total of 85 migratory bird species were recorded under 10 orders and 22 families. Individuals of wetland dependent migratory birds were higher than other bird species. Sonarchar Wildlife Sanctuary (SWS) had the highest number of bird species and individuals (70 species; n = 3618 individuals) with the highest diversity index values (H’ = 3.135, Ds = 0.9257) compared to two other sites. Significant variations among migratory avian communities were found among the three study sites as indicated by the Analysis of Similarity (ANOSIM) test (R = 0.168, P < 0.001) in the non-metric multidimensional plot (NMDs). Among the migratory bird species, Charadrius dubius (14.75%), Anas crecca (14.33%), Threskiornis melanocephalus (11.69%), Actitis hypoleucos 8.47%), Vanellus cinereus (6.75%) were the most abundant. Population abundance was higher for the occurrence of the wetland dependent migratory bird species in the study area. Avian community composition of migratory species showed uneven distribution in the rank abundance curve. Across the three study sites, the majority of the migratory bird species exhibited clumped distribution patterns, followed by regular and random distribution patterns. A total of 37 (45.12%) species of migratory birds were found to use the coastline as their microhabitat. Unplanned fishing, tourism, expansion of agricultural land, hunting, and pollution were identified as major threats to the migratory bird species in the study area. This study suggests community-based conservation measures are essential for the proper conservation of the migratory birds.

Japanese Encephalitis: A Clinical Review
Authors: Haque Md Azizul , Chowdhury Fazle Rabbi , Islam Md Nurul , Kabir Habiba , Ahasan HAM Nazmul
Published: February 2025

Japanese encephalitis (JE) is a severe disease caused by the Japanese encephalitis virus of the genus Flavivirus and the family Flaviviridae. Mosquitoes of the Culex Vishnu subgroup, particularly Culex tritaeniorhynchus, are the main vectors of JEV. This zoophilic mosquito species is sustained in an enzootic cycle with pigs and wading birds as amplifying hosts. JE is endemic to rural Asia, the Western Pacific, and northern Australia, with three billion people at risk. Globally, an estimated 68,000 clinical cases occur annually, and over 13,000 deaths. Most JEV infections are subclinical; symptomatic infection can cause a spectrum of clinical manifestations ranging from undifferentiated febrile illness and aseptic meningitis to acute encephalitis. One-third of JE infections are fatal, and half of the survivors develop permanent neurological sequelae. Because of the frequent neurological sequelae of the condition, JEV causes loss of more disability-adjusted life years than any other arthropod-borne virus. WHO recommends incorporating the JE vaccine into the routine childhood immunization program in all JE-endemic areas. However, not all JEV-affected countries, including Bangladesh, have the vaccine implemented in their routine immunization programs. Introducing a childhood vaccination program can significantly reduce the number of JE cases in Bangladesh.

Fostering Mental Wellbeing in Return Migrant Women
Authors: Bilkis Azmira , Saha Mili , Saha Goutam
Published: February 2025

Migrant women ventured overseas to work in domestic roles and came back to their home countries enduring different types of physical and psychological mistreatment. Among those who faced various forms of mistreatment during their migration, a significant number experienced mental health issues upon returning home. An example is a 28-year-old female migrant who was physically abused in Saudi Arabia and later developed psychosis after coming back home. This case study provides a detailed understanding of the observation process, highlighting that female migrants who return home encounter diverse forms of social harassment and stigma, such as social isolation, excessive anxiety, depression, fear, and loss of dignity. Consequently, the report recommends the expansion of mental health services and rehabilitation programs for female migrants upon their return.

Published: February 2025

A 58-year-old male presented with complaints of new-onset periodic tremors and spasms for a few days. The patient was found to have recently started a course of trimethoprim-sulfamethoxazole (TMP-SMX) due to concern for a suspected urinary tract infection found incidentally after presenting for wound dehiscence following L1-L4 laminectomies a month prior. A neurological workup revealed was unremarkable, resulting in the exploration of further potential causes. A literature review revealed a case report that reported myoclonus as an adverse effect of TMP-SMX. So, the medication was discontinued, resulting in a resolution of myoclonus. The purpose of this case report is to make clinicians aware of a rare reversible adverse drug reaction from the use of TMP-SMX.

Patients with Dress Syndrome often present resistance to traditional pharmacological therapies, which include the use of corticosteroids and pulse therapy. In severe and recurrent cases of this syndrome, the use of biological agents tends to be strongly recommended, allowing the prevention of possible deleterious outcomes. The present study aims to evaluate the efficacy of biological agents used for Dress Syndrome refractory to corticotherapy. For this scoping review, carried out through the PubMed and ScienceDirect platforms, between the years 2022 and 2025, the descriptors chosen were ‘’Drug Hypersensitivity Syndrome’’, ‘’Biological Products’’ and ‘’Adverse Drug Event’’. The inclusion criteria consisted of (1) Evaluation of the use and efficiency of biological agents, (2) Analysis of the management of Dress Syndrome refractory to corticosteroid therapy, (3) Studies comparing the performance of different immunobiological agents, (4) Texts addressing monitoring, follow-up and clinical management and (5) Articles in English and Portuguese. The exclusion criteria consisted of inappropriateness to the topic, case reports, editorials, studies with animals and texts outside the time limit. Patients with severe Dress who used biological agents early showed a reduction in acute lethal symptoms, as well as a reduction in the length of hospital stay and deleterious outcomes associated with high doses of corticosteroids. The studies demonstrated that compared to the elderly population, young individuals tend to have a better prognosis and therapeutic response. Recommendations regarding the interaction and discontinuation of such biological therapies are controversial topics to be elucidated through new studies.

O açaizeiro (Euterpe oleracea, Arecaceae) é uma palmeira nativa da Amazônia tradicionalmente explorada no sistema extrativista e cujos frutos são destinados à produção de bebida conhecida como vinho de açaí. Em razão do consumo crescente o extrativismo não atende o aumento da demanda e o açaizeiro passou a ser cultivado em áreas de terra firme na região amazônica. A interferência negativa de plantas daninhas é um fator que prejudica o crescimento das plantas e a produção de frutos nas lavouras em terra firme, exigindo a realização de controle periódico. O controle de plantas daninhas com herbicidas tem como vantagens obter eficácia de controle alta, menor custo, maior rendimento operacional e menor dependência de mão de obra. Os herbicidas seletivos controlam as plantas daninhas e não prejudicam o açaizeiro, contudo, são necessárias avaliações para o uso seguro dos herbicidas. Assim, este trabalho teve o objetivo de avaliar a seletividade dos herbicidas 2,4-D dimetilamina (670, 1005, 1340 e 1675 g), diuron (750, 1250, 1750 e 2250 g), fenoxaprop-p-ethyl (55, 82,5, 110 e 137,5 g), metribuzin (240, 480, 720, 960 g) e sulfentrazone (500, 750, 1000 e 1250 g). O experimento foi conduzido em condição de viveiro em vasos com plantas de açaizeiro, cultivar BRS Pai d’Égua, no estádio de cinco folhas completamente expandidas. O 2,4-D, diuron, metribuzin e sulfentrazone foram aplicados sob o dossel das mudas e o fenoxaprop-p-ethyl sobre as folhas. Todos os herbicidas em todas as doses foram seletivos para o açaizeiro, com fitotoxicidade considerada leve.

A tuberculose (TB) é uma infecção causada pela bactéria Mycobacterium tuberculosis, que afeta principalmente os pulmões e é transmitida por secreções orais. A doença, embora muitas vezes assintomática, é indicada por tosse persistente. Historicamente, a TB remonta às civilizações antigas e chegou ao Brasil com a colonização. A doença continua a ser uma das principais causas de morte por infecção bacteriana no mundo e teve sua situação agravada pela pandemia de COVID-19 e pela vulnerabilidade social. A pesquisa objetivou analisar fatores que sustentam a elevada prevalência da tuberculose na região norte do brasil O estudo na região Norte do Brasil analisou os registros de TB de 2015 a 2020, utilizando dados do DataSUS. A pesquisa foi quantitativa e identificou fatores como diabetes, tabagismo, alcoolismo e faixa etária, correlacionando-os com a prevalência da doença. Foi evidenciado que o Brasil registrou 540.370 casos, com 2019 destacando-se pelo maior número de infecções. Na região Norte, o Pará teve o maior número de casos, enquanto o Amazonas teve a maior taxa de prevalência. Fatores como tabagismo e alcoolismo mostraram-se principais riscos para o desenvolvimento de TB, com maior incidência entre homens e pessoas na faixa etária de 25 a 34 anos. O estudo reforça a alta prevalência da doença na região Norte e a necessidade urgente de medidas de controle e prevenção, destacando a tuberculose como um sério problema de saúde pública no Brasil.

Configurando cerca de um sexto da população brasileira, os jovens vem sendo uma preocupação recorrente para os acadêmicos desde o início do século XXI, em 2022, 12,7 milhões de pessoas entre 15 e 19 anos não estudavam e nem trabalhavam, é apontado que a principal causa para a evasão escolar seja o desinteresse pelos estudos. Sendo os jovens seres capazes de atribuir seus próprios sentidos e também uma classe dotada de diversidade é necessário olhar para as causas de tal desinteresse pelos estudos. O objetivo deste trabalho é olhar para as pluralidades das escritas acadêmicas sobre as juventudes, em especial, no contexto escolar, discorrendo sobre a subjetividade, a invisibilidade, a experiência e a identidade de estudantes do Ensino Médio. Para o desenvolvimento foram revisadas teses e dissertações produzidas por acadêmicos brasileiros. Os trabalhos revisados revelam o descontentamento dos jovens com algumas práticas comuns dentro da escola, como ideais conservadores que alguns professores tendem a tentar propagar, hegemonia, falta de reconhecimento das diferentes classes sociais em que estão inseridos os estudantes e sua consideração em atividades e avaliações. Alguns jovens relatam estar cursando o Ensino Médio apenas por obrigação ou para facilitar o processo de adesão ao mercado de trabalho, também não demonstram vontade de continuar a vida acadêmica por achar que as experiências negativas enfrentadas serão as mesmas. É reforçado a urgência de mudanças no modus operandi das escolas e a adoção de práticas mais inclusivas, democráticas e sensíveis às demandas das juventudes.

A fotobiomodulação (FBM) é uma técnica emergente utilizada como terapia coadjuvante no manejo da acne vulgar. O objetivo dessa revisão narrativa da literatura é apresentar a possibilidade de manejo da acne vulgar com o uso da fotobiomodulação.Esse método envolve o uso de luzes de baixa intensidade, como LEDs ou lasers, que são aplicadas diretamente na pele para estimular processos biológicos e promover a regeneração celular. A acne vulgar é uma condição cutânea comum que afeta milhões de pessoas, causando impacto significativo na qualidade de vida devido a suas manifestações clínicas, como pústulas, comedões e nódulos inflamatórios. Estudos demonstram que a FBM pode reduzir a inflamação e a quantidade de lesões acneicas ao modular a atividade das glândulas sebáceas e reduzir a proliferação de bactérias Propionibacterium acnes. Além disso, a FBM estimula a produção de colágeno, contribuindo para a cicatrização das lesões. Os tratamentos com FBM são geralmente bem tolerados, com poucos efeitos colaterais relatados, o que a torna uma alternativa viável e eficaz para pacientes que buscam opções além dos tratamentos farmacológicos tradicionais. Assim, a fotobiomodulação se apresenta como uma abordagem promissora, complementando os regimes terapêuticos convencionais e oferecendo benefícios significativos no controle e na melhoria das condições de acne vulgar.
