Published: July 2023

A temática do descarte inadequado de medicamentos e sua relevância no desenvolvimento dos mecanismos de resistência aos antibióticos são os menos debatidos na literatura. Portanto, este trabalho tem como objetivo apresentar e discutir os dados obtidos sobre o recebimento de antimicrobianos vencidos e/ou sem uso descartados no ponto de coleta de medicamentos localizado no Departamento de Ciências Farmacêuticas, da Universidade Federal de Pernambuco, Campus Recife. Ao todo foram recolhidos 50,03 kg de medicamentos, dos quais 4,12 kg eram de antimicrobianos, sendo a terceira classe farmacológica mais frequente; destes, 93,07% (n=1.948 unidades) estavam vencidos e a forma farmacêutica mais encontrada foram os comprimidos (36,32%). Entre as classes de antibióticos predominaram, em relação ao mecanismo de ação, os que inibem a síntese proteica (29,33%), e pela estrutura química, as quinolonas (17,45%). A realização do descarte adequado desses medicamentos possibilita uma redução dos impactos que esse quantitativo recolhido causaria no meio ambiente. Portanto, deve-se investir em campanhas de conscientização sobre o uso correto dos medicamentos e seguimento da prescrição médica para evitar consumo indiscriminado destes fármacos. Com base o que estabelece o Decreto n° 10.388/2020, o descarte correto de medicamentos precisa ser divulgado, para que os estabelecimentos realizem a logística reversa dessas substâncias.
HTLV-1 NA LEUCEMIA/LINFOMA DE CÉLULAS-T E ABORDAGEM SOCIAL SOBRE A INFECÇÃO
Authors: De Almeida Rafael Braz
Published: July 2023

A Leucemia/Linfoma de Células-T do Adulto (LLCT) é um tipo agressivo de doença linfoproliferativa causada pelo Vírus Linfotrópico de Células-T Humano (HTLV-1), classificada em cinco tipos: indolente, tumoral primária de pele, crônico, linfomatoso e agudo. O HTLV pertence à família Retroviridae, gênero Deltaretrovirus, subfamília Oncovirinae, de três genes estruturais (Gag, Pol e Env) e sua transmissão ocorre por contato sexual, transfusão de sangue ou inoculação por materiais perfuro-cortantes contaminados e aleitamento materno. Esta revisão narrativa tem como objetivo apresentar uma síntese sobre a relação do HTLV-1 na LLCT, seu processo patogênico e uma abordagem social. O vírus infecta, principalmente, células T CD4+, desregulando o sistema imunológico do hospedeiro, podendo ocasionar neoplasia de células-T a partir de uma única célula que teve expansão clonal, constituindo uma população monoclonal em que todas as células contêm o DNA proviral do HTLV-1. O prognóstico é ruim, a maioria dos pacientes que desenvolvem LLCT apresenta doença de progressão rápida e o óbito em curto período, mesmo com quimioterapia agressiva. Não há política nacional específica para o HTLV, não faz parte da lista de doenças de notificação compulsória e pouco se debate publicamente, gerando desconhecimento por parte da população e por parte de profissionais de saúde, sendo uma infecção negligenciada. Conclui-se que a infecção pelo HTLV é um tema que precisa ser popularizado, havendo urgência na implantação de políticas públicas específicas e de pesquisas contínuas, devido à grande incidência no Brasil e associação a doenças graves como a LLCT.

Authors: Weber César Augusto Trinta
Published: July 2023

A inclusão social de doentes mentais em serviços substitutivos à internação em hospital psiquiátrico é tema reconhecidamente tensionado tanto pelas noções que o envolvem quanto pela natureza do seu funcionamento. Foi realizada uma revisão bibliográfica não exaustiva com destaque para as principais posições teóricas sobre o tema da inclusão social no contexto da reforma do modelo de assistência psiquiátrica. Os resultados desses estudos demonstram que, apesar da reconhecida importância de tais objetivos no processo de inclusão social de doentes mentais, atingi-los na prática ainda encontra várias barreiras.

Published: July 2023

A estimulação transcraniana por corrente contínua (ETCC) é uma nova proposta terapêutica em rápido desenvolvimento nos últimos anos, parecendo ser uma técnica promissora para o tratamento de vários transtornos psiquiátricos. Esta consiste na aplicação de uma corrente elétrica direta no cérebro, que flui entre dois eletrodos relativamente grandes (cátodo e ânodo). Durante a ETCC, uma corrente elétrica de baixa intensidade é aplicada através do couro cabeludo, penetrando no crânio e chegando ao córtex cerebral e podendo modificar o potencial de repouso da membrana neuronal, e, por conseguinte, modulando a taxa de disparo neuronal. O maior número de estudos tem se concentrado no tratamento da depressão e esquizofrenia, com resultados bastante promissores. No caso do uso de drogas, a ETCC também parece ser uma abordagem que pode auxiliar na diminuição de sinais e sintomas de abstinência. Em outras situações, a ETCC aparece ainda com resultados preliminares. Assim, o presente artigo consiste em revisão sistemática da literatura sobre o uso da ETCC para o tratamento dos transtornos psiquiátricos.

Objetivo: Abordar a relação entre a Fibromialgia (FM) e saúde do trato gastrointestinal (TGI) e sua importância para o diagnóstico e tratamento da FM. Revisão bibliográfica: A FM é um quadro reumatológico caracterizado, principalmente, por dor crônica difusa. Outras manifestações possíveis envolvem fadiga, alteração do sono, acometimento cognitivo, distúrbios de humor e sintomas gastrointestinais. Existe uma relação muito próxima entre a FM e afecções gastrointestinais e o diagnóstico bem-feito, tal como a boa avaliação do paciente, são necessárias para alcançar o melhor resultado terapêutico possível. Considerações finais: Ainda que pouco elucidada, há uma estreita correlação entre a FM e o TGI. Portanto, é importante valorizar a sintomatologia e conhecer a relação bidirecional entre FM e afecções do TGI, sobretudo a síndrome do intestino irritável (SII). Contudo, necessitamos de mais estudos que explorem a etiopatogenia e a fisiopatologia da FM, tal como a influência do TGI nesses aspectos, para melhorar tanto o diagnóstico quanto o tratamento da FM.

JAK inhibitor: Introduction
Authors: Raychaudhuri Siba P. , Raychaudhuri Smriti K.
Published: July 2023

The Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway is a key regulatory signaling system for cellular proliferation, differentiation, and apoptosis. In addition, JAK signaling pathway plays critical roles in orchestrating immune response through its interactions with the cytokine receptors and the transcriptions factors. Several key cytokines use JAK-STAT signaling proteins to transduce intra-cellular signals which are involved in the pathogenesis of autoimmune and inflammatory diseases such as in psoriatic disease (psoriasis, psoriatic arthritis), atopic dermatitis, alopecia areata, vitiligo, rheumatoid arthritis, ankylosing spondylitis, lupus erythematosus, Sjogren’s syndrome, and other autoimmune diseases. In recent years, understandings of the molecular mechanisms of JAK-STAT pathway in the inflammatory proliferative cascades of autoimmune diseases has led to the development of JAK inhibitors and has opened a new dimension for the treatment of systemic and cutaneous inflammatory diseases. In this symposium we have provided a broad perspective on the use of Janus kinase inhibitors in cutaneous autoimmune diseases.
Multifocal malignant peripheral nerve sheath tumor in patients with neurofibromatosis type I: Report of two cases and review of literature
Authors: Salem Raghad Hany , Almutairi Othman T. , Bafaquh Mohammed Saeed
Published: July 2023

Background:

Malignant peripheral nerve sheath tumors (MPNSTs) are one of the rarest soft-tissue sarcomas with a prevalence of 0.001% in the general population. It is closely associated with a unique neurocutaneous stigmata under the spectrum of the dermatological manifestations of neurofibromatosis type 1 (NF1). Almost 81% of MPNST arises from a precursor neuroma, and multifocality of these lesions is extremely rare, making up to 0.001% of cases. Moreover, spinal cases are extremely uncommon with only four cases reported internationally. Here, we present the fifth and sixth spinal MPNST cases with a brief review of literature.

Case Description:

We describe two unusual cases of multifocal MPNST in relation to NF1 occurring in the spinal cord. Both patients presented with local pain and myelopathic symptoms. The two patients underwent wide surgical resection, followed by neoadjuvant radiotherapy and reported immediate postoperative improvement of the presented complaint; however, one patient suffered from rapid recurrence and metastasis.

Conclusion:

Due to the scarcity of spinal cases related to MPNST, no clear guidelines regarding the management of these cases are set in the literature. Histopathological diagnosis remains as the most pivotal diagnostic tool as they can mimic other peripheral nerve sheath lesions, such as neuromas and schwannomas, in imaging. Cases that were managed by early surgical intervention in addition to neoadjuvant radiotherapy reported the best outcome. However, cases of MPNST in concomitance with NF1 were found to be resistant to both chemo and radiotherapy and have high recurrence rate.

Authors: Santangelo Gabrielle , Singh Aman , Rahmani Redi , Kessler Alexander , Bender Matthew
Published: July 2023

Background:

Extradural arteriovenous fistulas (AVFs) of the cervical spine are extremely rare, and typically manifest as slowly progressive myelopathy caused by mass effect. This is a unique case of extradural AVF of the cervical spine manifesting with purely radicular symptoms and treated endovascularly with coil and liquid embolization.

Case Description:

A 55-year-old woman presented with neck pain and right upper extremity radiculopathy persisting for 9 months. Imaging studies demonstrated an AVF spanning from C4–C6 with extension into the C5–C6 foramen supplied primarily from the deep cervical branch of the costocervical trunk. The patient underwent successful coil and liquid (Onyx) embolization. Six-week postoperatively, the patient’s symptoms completely resolved and magnetic resonance imaging and angiographic imaging confirmed complete obliteration of the fistula.

Conclusion:

While extradural AVFs typically present with myelopathic symptoms, they may present with solely radicular symptoms and can be successfully treated endovascularly.

Published: July 2023

We present a summary of the recently held Third International Siberian Neurosurgical Conference (Sibneuro 22). Professional education, scientific exchange, and social interactions are essential in neurosurgical practice. In addition to the main program of the Congress, there were two practical pre-meeting courses: on aneurysm clipping and on intraoperative neuromonitoring. In addition, there was a 1-day seminar focusing on a role of laboratory diagnostics in neurosurgical practice. Within the framework of the Siberian Congress, there was a session devoted to inventions in neurosurgery, a rare subject of discussion at neurosurgical events. Our educational event is very important for the Siberian neurosurgery. Neurosurgeons of Siberia are a part of the world neurosurgical family. We not only try providing high-quality neurosurgical care to patients but also maintaining the academic level of education and scientific activity. The next - fourth - Siberian Neurosurgical Congress will take place in July 2024 in Irkutsk.
The rule of five: A novel anatomical landmark for approaching cavernous sinus content
Authors: Mejia Juan Armando , Nova Maximiliano Paez , Rairan Luis Garcia
Published: July 2023

Background:

The main objective of this study is to enhance neurosurgeons’ anatomical knowledge by providing specific anatomical references of the cavernous sinus (CS). However, it is essential to clarify that our study does not seek to establish an absolute intraoperative rule due to the inherent anatomical variability that must be considered.

Methods:

Fifty-three cadaveric specimens were procured from the Forensic Institute (Bogotá) and subjected to dissection through an extradural approach. The measurements were taken in two distinct phases. The first phase involved the measurement of various anatomical structures in 25 specimens with respect to the anterior and posterior clinoids. The second phase, which was conducted 5 years later, involved the measurement of the distance between the foramen rotundum and the foramen ovale in 28 specimens using the L&W tools microcaliper.

Results:

In 25 specimens, a perpendicular imaginary line was drawn from the lateral tip of the anterior clinoid to the floor of the medial fossa. This facilitated access to the Parkinson’s triangle, which is located between the IV cranial nerve and the ophthalmic V1 nerve, revealing a constant distance of 5 mm between the lateral tip of the anterior clinoid and the IV cranial nerve. Furthermore, in 28 specimens, the mean distance from the foramen rotundum to the foramen ovale was found to be 1.3 cm bilaterally.

Conclusion:

The rule of five is a valuable tool for comprehensively understanding the anatomy of the CS, providing a reference point for the different normal anatomical structures within the CS.

Time series is sequential data based on time sequence. Time series data can be used for prediction topics, one of the prediction topics that is always interesting to study is exchange rate prediction. In the case of exchange rate prediction, an appropriate data preprocessing stage is required. The success of this preprocessing stage will have a major effect on the resulting RMSE value. There is an important technique in determining the best RMSE value, especially in time series data, one of which is the windowing technique. The windowing technique is the stage of transforming time series data into cross sectional. Window size has an important role in time series data. However, there is no standard in window size. The Window size experiment starts with a small value and then increases to a larger value until it reaches a certain point with the best RMSE. In this research, an experiment will be conducted on windows size on exchange rate data based on a neural network. The purpose of this research is to optimize the RMSE of a data mining model based on windows parameters. The implementation of sliding windows is carried out in the scenarios of window sizes 4, 6, and 28. Based on the experiments conducted, the best RMSE is on windows size 6 = 0.014 +/- 0.000. With a combination of neural network parameters in the form of training cycles = 1000, learning rate = 0.1 and momentum = 0.1.
Ode to Repair: Weaving and Restoration in the Work of Louise Bourgeois
Authors: Ignatenko Galina S.
Published: July 2023

Contemporary art practitioners use a rich arsenal of techniques and materials, including those previously considered by artists to be applied and therefore of secondary importance. Threads and fabrics have long been confined to the field of fine and decorative arts and have not been considered full participants in the art scene. Until now the boundaries between textile art and high art remain blurred. However, at the end of the twentieth century, we saw a new strategy for the perception of textiles and domestic handicraft practices as independent art forms. The change in the traditional hierarchy and language of art in the 1960s and 1980s was influenced by many developments, including the emergence of a new wave of artists who began to incorporate applied materials into the space of art. The legalisation of textile production as an artistic practice owed much to Louise Bourgeois, who turned to needlework techniques and demonstrated their limitless potential. The material for this article is the textile works of Louise Bourgeois, her memoirs, as well as video materials and the documentary film “The Spider, the Mistress and the Mandarin”. This article analyses textile works of the artist, as well as the themes of damage and restoration that run through many of her works. The term “mending” is discussed, which seems broader and more relevant to describe Bourgeois’ works. The image of the spider, a symbol of mother and weaver, which is important for the artist, is also analysed. In the orbit of the author’s attention is the theme of duality of needle as a simultaneous image of traumatisation and reparation. The conclusion is made that L. Bourgeois’ work has influenced artists from the 1970s to the present day. Her creative language, the variety of materials and techniques used have enriched the arsenal of contemporary art and have certainly influenced the place of textile in the hierarchy of arts.
Data Efficient and Stability Indicated Sampling for Developing Reactive Machine Learning Potential to Achieve Ultra-long Simulation in Lithium Metal Batteries
Authors: Xu Longkun , Shao Wei , Jin Haishun , Wang Qiang
Published: July 2023

Modelling the formation of solid-liquid interphase (SEI) is challenging as its strict requirement with both simulation accuracy and length. Machine learning potential (MLP) based molecular dynamics (MD) simulation is expected to play a role in this field while currently its use is hindered by sampling efficiency and simulation stability. In this work, we tackle the two challenges together. We propose the stability-indicatedsampling (SIS) algorithm for efficiently sampling training data using physical information (temperature). Unlike previous strategies, our method does not need prior knowledge of reaction networks or training multiple MLPs for uncertainty estimation. Compared with the recent proposed methods HAIR and DP-GEN, our approach gives significant improvement of sampling efficiency with less requirements with the initial training data, to realize > 10 ns MLPMD simulation using ab initio MD (AIMD) trajectory of just a few ps. We introduce the concept underlying instability consistency by showing the accuracy of reaction mechanisms and radial distribution function (RDF) can be improved by SIS-MLPMD, although their information is not explicitly used in our sampling decision. Furthermore, we show that long-time MLPMD simulation of Lithium metal battery (LMB) can not only reproduce some well-known SEI components including LiF, Li2O, LiOH, LiS and the incomplete N-S breaking in highconcentration systems, but also ionic aggregation structures of LiF, which is not shown in our AIMD training data but matches previous results of electrochemical impedance spectroscopy. Our work is expected to help accelerate future investigations, especially for studying long-time (≥ ns scale) reaction dynamics in interfacial problems.

Authors: Abdelhamid Hani Nasser , Hashem Zeinab Hussein , Abdel-Rahman Laila H. , Gomez Santiago
Published: July 2023

Hydrogen gas (H2) is widely acknowledged as a sustainable and environmentally friendly energy carrier. In this study, we examined the potential of copper-based metal-organic frameworks (MOFs); copper-benzene-1,3,5-tricarboxylate (Cu-BTC), as catalysts for the release of hydrogen through the hydrolysis of sodium borohydride (NaBH4). Cu(BTC) exhibited a hydrogen generation rate (HGR) of 4386 mLH2 gcat-1 min-1 using low catalyst loading of 1 mg. The effect of the reactant weight percentage of NaBH4 )0.2-3 wt.%) at room temperature was investigated. Thermal analysis of the hydrolysis process revealed that Cu-BTC MOF exhibits low activation energy of 41.7 kJ mol-1. The study investigated the recyclability of the catalyst and found that it could sustain catalytic hydrogen generation for up to four cycles without any noticeable decline in performance. This research demonstrated that Cu(BTC) is an inexpensive, efficient, and reusable catalyst for generating hydrogen through hydride hydrolysis.
O-vacancy Mediated Partially Inverted Ferrospinels for Enhanced Activity in the Sulfuric Acid Decomposition for Hydrogen Production
Authors: Pathak Shailesh , Bhumla Preeti , Bahri Shashank , Upadhyayula Sreedevi , Bhattacharya Saswata
Published: July 2023

Understanding tailored CO3O4 spinel with Fe3+ doping is challenging due to the surface state characterization of bifunctional catalysts with higher cation diversity. Doping the secondary metal creates a double spinel structure (a hybrid of normal and inverted spinels), enhancing catalytic properties by generating more active oxygen vacancies. Cobalt-rich (FeCo2O4) hybrid spinel and iron-rich (CoFe2O4) inverted spinel are synthesized using a wet impregnation method, supported over oxidized SiC (pretreated SiC) for improved metal-support interaction. FeCo2O4 on pretreated SiC exhibits the highest catalytic activity (90% conversion at 1173 K) and stability (over 100 h) in the sulfuric acid decomposition of the iodine-sulfur (IS) process for hydrogen production. This improved performance is attributed to the high electronegativity of Co3+, oxygen vacancies, and strong metal-support interaction. The high electronegativity of Co3+ weakens the S-O bond in M-S-O, enhancing the catalytic activity of the spinels. These results are further corroborated by detailed characterization and density functional theory calculations.

Is the role of universities and colleges vital in employment generation? Can indian universities afford to ignore? At what cost? Who pays?
Authors: Naik B. M.
Published: July 2023

This paper presents the need and importance of productive employment, which is a significant issue in India. The government is currently considering sustained scientific efforts such as technological innovation, creativity, and start-ups in hi-tech through higher education to generate jobs. The education offered by universities follows traditional methods and does not align with the changing world. Governments are now exploring opportunities and scopes to generate productive employment through innovation, incubation, and research parks, among others. It is observed that a strong, innovative university system is a prerequisite for increasing the employability of graduates and for employment generation and development. It is recommended to urgently take steps to create entrepreneurs, new knowledge, new technology, patents, and intellectual property rights, and establish technology-based firms in partnership with the industry. This paper presents the new role and responsibility of universities and colleges in imparting education in an innovative way, fostering synergy with industry, and keeping up with fast-advancing technology. This has become essential in these changing times, especially under globalization pressures. Case studies from developed countries are presented in support of this. It is recommended that funding agencies such as the World Bank, UNESCO, the Asian Development Bank, and developed countries prioritize reforms in higher education and guide India in increasing employability for productive jobs. This paper briefly presents problems in the adoption and implementation of innovation methods. Policy implications in this effort to generate jobs are identified and presented to facilitate the government's adoption of new approaches to fulfill the growing aspirations of the people. Conclusions are drawn to enhance the employability of graduates by making them creative and innovative for job generation.

Employees in the public and private sectors who work to assist the sector's expansion are considered to be talented. The performance and value an organization can deliver are highly dependent on the knowledge, skills, and motivation of the people responsible for delivering the various services. These are probably the most important inputs to the system. Despite the large size of public sector organizations, the private sector still provides most services, currently providing 70% of services. The hospitality industry requires a multidisciplinary set of skills and knowledge and employs a wide variety of different categories of employees. It has been observed that supervisory staff, middle management, and senior executives play an important role in the provision of hospitality services. Hotel managers must be aware of the qualitative and quantitative needs of different departments and manage different aspects of personnel management in an appropriate manner. However, lower occupancy rates, higher capacity, shorter guest stays, and the erosion of a hotel's once-sacred image are all effects of a dynamic and complex hospitality environment. Last but not least, "quality of care" is the most important issue in the hospitality industry, related to inadequate guest care and guest preferences and choices. Business growth and performance concerns are inseparable from this issue.

Social media significantly contributes to the online community by connecting people who communicate and share knowledge. Facebook, Wikipedia, Twitter, WhatsApp, Pinterest, LinkedIn, Instagram, and Reddit are some of the most popular social media sites. These are not only social networking sites but also places where people can divulge personal information to the public and the community. Additionally, business owners sell their products on social media and profit from crowdfunding. Data analytics gather and analyze social networking platform data, enabling businesses to make wise decisions. Students and young people are greatly impacted by social media, which influences their consideration of human nature and the inadvertent development of fanaticism and avarice. Therefore, social media is used to both elevate and degrade people from all walks of life. This study shows the positive and negative impact of social media on youth in different sectors.

Objective: To study the predictive value of serum pregenomic RNA (pgRNA) on HBeAg clearance in patients with chronic hepatitis B with low HBeAg levels during pegylated interferon therapy. Methods: Twenty chronic hepatitis B patients with HBeAg positive and quantitative <50S/CO were selected for this study. The subjects underwent pegylated interferon therapy for 48–96 weeks and were followed up in the outpatient clinic after treatment. The patients were then divided into groups based on whether their HbeAg turned negative. The predictive ability of each indicator for HBeAg negative conversion was evaluated in the HBeAg negative group and the HBeAg positive group. Results: The results of logistic regression analysis suggested that pgRNA and HBcrAg were better indicators for predicting the clearance of HBeAg after treatment. Conclusion: For patients with chronic hepatitis B with low HBeAg levels, pgRNA is a good indicator in predicting HBeAg clearance during pegylated interferon therapy.
LAS NORMAS Y ESTRUCTURAS DE INTELIGENCIA EN ARGENTINA, BRASIL Y CHILE, DESDE LA RESTAURACIÓN DEMOCRÁTICA HASTA HOY, PERSPECTIVAS Y PROYECTOS EN CURSO
Authors: Ugarte José Manuel
Published: July 2023

Un análisis comparativo de las normas y estructuras de inteligencia en Argentina, Brasil y Chile muestra a tres países que con diferencias exhibían no obstante significativas similitudes durante la Guerra Fría, período durante el cual conocieron años de gobiernos militares. Tales similitudes comenzaron a disminuir tras la restauración democrática en ellos, mostrando evoluciones divergentes entre sí, pero con significativo paralelismo dentro de cada país con la evolución registrada en materia de relaciones civiles-militares. Mientras Argentina mostró un fuerte desarrollo de la inteligencia civil, con controles insuficientes y frecuentes denuncias por irregularidades, y la retirada de la inteligencia militar de la seguridad interior, Brasil fue consolidando la conducción militar de la inteligencia civil y militar, limitado en los últimos días por medidas adoptadas por un recién asumido gobierno, que debió enfrentar una seria crisis militar. Chile, por su parte, muestra la lenta y paulatina evolución de una inteligencia civil recreada tras la restauración democrática, originariamente tenue, pero que va paulatinamente consolidándose, aspecto que podría ser favorecido por proyectos en curso, mientras que la inteligencia militar permanece, en lo fundamental, fuertemente orientada a la defensa. Los tres países muestran la necesidad de un fortalecimiento de los controles en la materia, aspecto común a las estructuras de inteligencia latinoamericanas. El trabajo, además del análisis comparativo referido, efectúa propuestas.

A direct potentiometric titration method was applied to commercial and soil humic acids inorder to determine their carboxyl and phenol group concentrations and apparent and intrinsic pK. Inthat context, acid-base properties of humic acids are interpreted by selective blocking of carboxylic andphenolic groups by esterification and acetylation. Differences in underivatized and derivatized HA’sacid-base properties are ascribed to carboxyl and phenol groups influence on total humic acidity.Potentiometric data were treated with the modified Henderson-Hasselbalch equation. Infra red results,the acidic group contents and the average values of apparent and intrinsic pK for underivatized andderivatized HAs confirmed the selectivity of esterification derivatization method. After blocking of thefunctional groups, the values of acidic group contents decreased, while the value of apparent pKincreased after derivatization. Phenol groups cannot be specifically identified by the acetylationmethod, due to low selectivity of the acetylation method.

Pothomorphe umbellata (L.) known on Brazil as Caapeba has a number of popular medicinaluse, and it has been studied in relation to its pharmacological activity. Peroxidase specific activity(units/mg protein) was evaluated in callus cell culture samples of the P.umbellata, grown in two differentMS medium (media 1 and media 2), submitted to 16 hours photoperiod or kept in darkness. Cell growthrate curve showed that the best growth indices were observed when media 2 submitted to the photoperi-od regime was used, followed by the same media kept in darkness (stress condition). The results obtainedalso showed that the cell culture grown under stress conditions (darkness) lead to high content of peroxi-dase enzyme (an increase of 700% was observed). Kinetic constant values of 3.3 mmol.L-1 and 2,8 sec-1were obtained for k M and v max ,, respectively, using guaiacol as enzyme substrate.
