Impact of an intervention program on drug adherence in patients with ulcerative colitis: Randomized clinical trial.

AIMS: Evaluate the impact of an intervention program in non-adherent patients with ulcerative colitis. METHODS: Parallel controlled randomized clinical trial (1:1), approved by the ethics committee (No. 3.068.511/2018) and registered at The Brazilian Clinical Trials Registry (No. RBR-79dn4k). Non-adherent ulcerative colitis patients according to the Morisky-Green-Levine-test were included. Recruitment began in August 2019 until August 2020, with 6-month follow-up. All participants received standard usual care, and additionally the intervention group received educational (video, educational leaflet, verbal guidance) and behavioral interventions (therapeutic scheme, motivational and reminder type short message services). Researchers were blinded for allocation prior to data collection at Visits 1 and 2 (0 and 6 months). Primary outcome: 180-day adherence rate, with relative risk 95%CI. Secondary outcome: 180-day quality of life according to SF-36 domains, using Student's t test. Variables with p<0.20 were selected for regression. Analysis included data from August/2019 to May/2021. RESULTS: Forty-six and 49 participants were allocated in control and intervention groups, respectively. Two were excluded due to intervention refusal, and 4 and 6 were lost to follow-up in control and intervention groups. There was no post-intervention adherence rate difference, even after adjustment for type of non-adherence (unintentional/both/intentional) as confounder, or if considered as adherent the intervention group participants lost in follow-up. Interventions promoted better quality of life scores even after multivariate analysis for "Pain", when adjusted for ulcerative colitis severity, sex, and marital status (ß = 18.352, p = 0.004), "Vitality", when adjusted for ulcerative colitis severity (ß = 10.568, p = 0.015) and "Emotional Aspects", when adjusted for disease severity, income, and education (ß = 24.907, p = 0.041). CONCLUSIONS: The intervention program was not able to produce a significant medication adherence rate difference between comparative groups, however, there was a significant improvement in quality of life. Study limitations may include: sample size calculated to identify differences of 30%, leading to a possible insufficient power; non blinded participants, exposing the results to the risk of performance bias; outcomes based on self-reported data.

Tyramine exerts hypolipidemic and anti-obesity effects in vivo

Abstract Obesity and dyslipidemia are conditions often associated with cardiovascular risk, inflammation, oxidative stress, and death. Thus, a new approach has been highlighted to promote research and development of pharmacological tools derived from natural sources. Among the most widely studied groups of substances, polyphenols such as tyramine stand out. This study investigated hypolipidemic and anti-obesity properties of tyramine. Oral toxicity evaluation, models of dyslipidemia and obesity were used. To induce dyslipidemia, Poloxamer-407 (P-407) was administered intraperitoneally. In the hypercholesterolemic and obesity model, specific diet and oral tyramine were provided. After 24h of P-407 administration, tyramine 2 mg/kg (T2) decreased triglycerides (TG) (2057.0 ± 158.5 mg/dL vs. 2838 ± 168.3 mg/dL). After 48h, TG were decreased by T2 (453.0 ± 35.47 vs. 760.2 ± 41.86 mg/dL) and 4 mg/kg (T4) (605.8 ± 26.61 760.2 ± 41.86 mg/dL). T2 reduced total cholesterol (TC) after 24h (309.0 ± 11.17 mg/dL vs. 399.7 ± 15.7 mg/dL); After 48h, 1 mg/kg (T1) (220.5 ± 12.78 mg/dL), T2 (205.8 ± 7.1 mg/dL) and T4 (216.8 ± 12.79 mg/dL), compared to P-407 (275.5 ± 12.1 mg/dL). The treatment decreased thiobarbituric acid reactive substances and nitrite in liver, increased superoxide dismutase, reduced the diet-induced dyslipidemia, decreasing TC around 15%. Tyramine reduced body mass, glucose, and TC after hypercaloric feed. Treatment with 5 mg/L (0.46 ± 0.04 ng/dL) and 10 mg/L (0.44 ± 0.02 ng/dL) reduced plasma insulin (1.18 ± 0.23 ng/dL). Tyramine increased adiponectin at 5 mg/L (1.02 ± 0.02 vs. 0.83 ± 0.02 ng/mL) and 10mg/L (0.96 ± 0.04 ng/mL). In conclusion, tyramine has low toxicity in rodents, has antioxidant effect, reduces plasma triglycerides and cholesterol levels. However, further studies should be conducted in rodents and non-rodents to better understand the pharmacodynamic and pharmacokinetic properties of tyramine

Hypertriglyceridemia promotes dysfunctions in high-density lipoprotein increasing the cardiovascular risk

Abstract Hypertriglyceridemia is associated with several metabolic diseases. The triglycerides (TG) disrupt the cholesterol reverse transport and contribute to increased levels of low-density lipoprotein (LDL). High-density lipoprotein (HDL) acts in cholesterol reverse transport as an anti-inflammatory and antioxidant. This study aims to investigate the role of hypertriglyceridemia in the functionality of HDL. Individuals were divided into 4 groups based on high or low HDL-c and triglycerides levels. Biochemical and anthropometric analysis were performed. This study demonstrated that triglycerides promote dysfunctions on HDL, increasing the cardiovascular risk. Blood pressure was higher in subjects with low HDL. Women presented higher levels of HDL-c and low percentage of fat mass. The highest levels of triglycerides were observed in older age. In addition, high levels of triglycerides were associated with higher total cholesterol and LDL-c levels, non-HDL-c, non-esterified fatty acids, and blood glucose, increasing in the ratio of non-HDL-c/HDL-c and ApoB/ApoA-I. The increase of triglycerides levels progressively impairs the antioxidant capacity of HDL, probably due to a higher occurrence of fatty acid peroxidation in individuals with hypertriglyceridemia. Patients with high HDL and low TG levels increased the Lag Time. Furthermore, a positive correlation was found between TG versus HDL particle size, variables that depend on age and anthropometric parameters.

The tribe Phaseoleae s.l. (Leguminosae-Papilionoideae) in the municipality of Caetité, Bahia State, Brazil / A tribo Phaseoleae s.l. (Leguminosae-Papilionoideae) no município de Caetité, Estado da Bahia, Brasil

Phaseoleae s.l. comprises the largest tribe of subfamily Papilionoideae in number of genera, with 89 genera and 1,567 species. Regional taxonomic studies of the tribe are only occasional in Brazil and rare in Northeastern Brazil, including Bahia, the region's most species-rich state. In this context, the present study had as its objective to carry out a taxonomic study of the species of Phaseoleae s.l. occurring in Caetité (BA), a conservation priority region for the Caatinga vegetation. For this purpose, we made field expeditions and visited to the HUNEB-Collection Caetité and HUEFS Herbaria. A total of 25 species and 15 genera were recorded, accounting for 23% of the species registered for Bahia. Caetité stands out as one of the main centers of floristic richness of Phaseoleae s.l. in the semi-arid region of Bahia state. Leaflet shape, inflorescence type and the coloration of the petals and seeds are the most useful characters for identification.

Os estudos taxonômicos regionais da tribo são pontuais no Brasil e raros no Nordeste do Brasil, incluindo a Bahia, o Estado mais rico em espécies da região. Neste contexto, este trabalho teve como objetivo realizar o tratamento taxonômico das espécies de Phaseoleae s.l. ocorrentes em Caetité (BA), uma região de prioridade de conservação para a vegetação de Caatinga. Para tanto, foram realizadas expedições de coleta e visitas aos Herbários HUNEB-Coleção Caetité e HUEFS. Um total de 25 espécies e 15 gêneros foi registrado, o que representa 23% das espécies registradas para a Bahia. Caetité destaca-se como um dos principais centros de riqueza florística de Phaseoleae s.l. no semiárido baiano. O formato dos folíolos, tipo de inflorescência e a coloração das pétalas e das sementes são os caracteres mais úteis na identificação dos táxons.

The Effects of the Alkaloid Tambjamine J on Mice Implanted with Sarcoma 180 Tumor Cells.

The tambjamines are a small group of bipyrrolic alkaloids that, collectively, display a significant range of biological activities including antitumor, antimicrobial and immunosuppressive properties. The key objective of the present study was to undertake preclinical assessments of tambjamine J (T-J) so as to determine its in vivo antitumor effects. To that end, sarcoma 180 cells were transplanted in mice and the impacts of the title compound then evaluated using a range of protocols including hematological, biochemical, histopathological, genotoxic and clastogenic assays. As a result it was established that this alkaloid has a significant therapeutic window and effectively reduces tumor growth (by 40 % and 79 % at doses of 10 and 20 mg/kg/day, respectively). In this regard it displays similar antitumor activity to the anticancer agent cyclophosphamide and alters animal weight in an analogous manner.

Avaliação do limiar anaeróbio pela variabilidade da frequência cardíaca em diabéticos tipo 2 / Evaluation of anaerobic threshold by heart rate variability in type 2 diabetics

A diabetes é um problema de saúde pública devido a sua alta prevalência, morbidade e mortalidade. O tipo 2 é mais prevalente e representa de 90 a 95% dos casos, sendo as complicações mais comuns o acúmulo de gordura no músculo esquelético e a resistência à insulina. O exercício físico regular contribui para regulação da glicemia, destacando-se o limiar anaeróbio como importante marcador para prescrição de exercícios físicos. OBJETIVO: Avaliar o limiar anaeróbio de indivíduos com diabetes tipo 2 através da variabilidade da frequência cardíaca. MATERIAIS E MÉTODOS: Estudo de caráter transversal, recrutou 18 participantes de ambos os sexos em uma unidade básica de saúde do município de Lagarto-SE, esse foram divididos em 2 grupos de 9 indivíduos. Na análise estatística utilizou-se o teste de Shapiro-Wilk para avaliação da normalidade e posteriormente Anova com pós teste de Tukey para comparação dos grupos. O grupo 1 composto de indivíduos diabéticos tipo 2 e o grupo 2 de indivíduos saudáveis. Também foi avaliada a média da frequência cardíaca em repouso e após o teste de esforço progressivo. RESULTADOS: As características de idade foram homogêneas sendo o grupo 1 com média de 62,1 (±13,9) anos e grupo 2 de 62,0 (±7,0) anos. A média da frequência de repouso foi de 79,8 bpm do grupo diabéticos e 78 bpm do grupo comparação, no limiar anaeróbio foi de 111,5 no grupo 1 e 119 no grupo 2. O tempo para atingir o L.A foi similar entre os grupos, 9,5 min no grupo experimental e 8 min no grupo comparação. CONCLUSÃO: Os valores do limiar anaeróbio de ambos os grupos foram considerados de baixo condicionamento físico, estes não apresentaram diferença estatística.

Diabetes is a public health problem due to its high prevalence, morbidity and mortality. Type 2 is more prevalent and accounts for 90 to 95% of cases, with the most common complications being the accumulation of fat in skeletal muscle and insulin resistance. Regular physical exercise contributes to glycemic regulation, highlighting the anaerobic threshold as an important marker for prescribing physical exercises. OBJECTIVE: To assess the anaerobic threshold of individuals with type 2 diabetes through heart rate variability. MATERIALS AND METHODS: A cross-sectional study, recruited 18 participants of both sexes in a basic health unit in the municipality of Lagarto-SE, which were divided into 2 groups of 9 individuals. In the statistical analysis, the Shapiro-Wilk test was used to assess normality and subsequently Anova with Tukey's post-test to compare the groups. Group 1 consisted of type 2 diabetic individuals and group 2 of healthy individuals. The mean heart rate at rest and after the progressive exercise test was also evaluated. RESULTS: Age characteristics were homogeneous, with group 1 averaging 62.1 years (± 13.9) and group 2 62.0 years (± 7.0). The mean resting frequency was 79.8 bpm in the diabetic group and 78 bpm in the comparison group, at the anaerobic threshold it was 111.5 in group 1 and 119 in group 2. The time to reach the LA was similar between groups , 9.5 min in the experimental group and 8 min in the comparison group. CONCLUSION: The values of the anaerobic threshold of both groups were considered of low physical conditioning, these did not present statistical difference.

Comparison of early cardiovascular risk among Brazilian and African university students.

Cardiovascular diseases are among the main causes of mortality worldwide, and dyslipidemia is a principal factor risk. Hence the study of biochemical markers is necessary for early diagnosis. OBJECTIVES: Evaluate biomarkers to diagnose the risks of cardiovascular diseases in healthy Brazilian and African young adults. DESIGN & METHODS: Weight, height, waist circumference, percentage of body fat and systemic blood pressure were measured; and fasting blood samples were taken for biochemical analysis. Triglycerides, total cholesterol, HDL-c, and apolipoproteins A-I and B were measured on automated equipment using commercially available kits, in addition to the tests of antioxidant capacity of HDL and the enzymatic activity of Paraoxonase 1. RESULTS: After statistical analysis, it was found that BMI, WC, fat (%), triglycerides, ApoB/ApoA-I ratio and Vmax were higher in Brazilians, while HDL-c, ApoA-I, Lag Time, Vmax and PON1 activity were higher in Africans. In Brazilians, the ApoB/ApoA-I ratio was related to obesity factors and lipid profile, but in Africans it was related only to lipids. The antioxidant capacity of HDL and PON1 activity was better in Africans. Through independence testing, we observed an association with moderate risk of myocardial infarction with gender in Africans. In the binary logistic regression analysis, it was found that men in general - and particularly African men - have higher risk of myocardial infarction than women; Odds Ratio 2144 (CI95%: 1343-3424) and 2281 (CI95%: 1082-4811), respectively. CONCLUSIONS: The anthropometric and biochemical parameters of Brazilians, especially men, predispose them to greater risks of cardiovascular diseases.

Parâmetros de avaliação e diagnóstico para lesão renal e aplicabilidade na rede pública e privada de saúde / Evaluation and diagnosis parameters for renal injury and applicability in the public and private health network

Introdução: o diagnóstico precoce e a detecção de fatores de risco para o desenvolvimento da lesão renal são difíceis devido a múltiplas etiologias e por ser assintomática, levando ao diagnóstico tardio e alta morbimortalidade. Objetivo: analisar e correlacionar os parâmetros de avaliação e diagnóstico para lesão renal e sua aplicabilidade nas esferas pública e privada de saúde de Rio Verde, Goiás. Método: trata-se de um estudo de campo, transversal e de abordagem quantiqualitativa. Foi feita uma busca ativa de médicos especialistas e não especialistas em Nefrologia e Urologia, na rede pública e privada de saúde de Rio Verde e foram aplicados questionários aos mesmos. Resultados: foram abordados 93 médicos, sendo que 76 médicos concordaram em responder os questionários, constituindo a amostra final do estudo. Destes, a maioria homem, com média entre 6 a 10 anos de formado, 80% com pós-graduação e 33,3% com vínculo exclusivo com o serviço público. A propedêutica médica prevalente aplicada nos pacientes com suspeita de lesão renal baseou-se em marcadores tardios de lesão renal, como a creatinina, a ureia sérica e o exame de urina e fracamente em exames que detectam mais precocemente a lesão renal, como a microalbuminúria e o clearence de creatinina. Não houve diferença significativa entre a propedêutica aplicada na rede pública e privada de saúde de Rio Verde. Conclusão: os dados do presente estudo demonstraram que o diagnóstico da lesão renal é tardio e servem para otimizar as condutas médicas locais, podendo motivar diagnósticos cada vez mais precoces dessas lesões, o que propiciaria redução nos custos e melhoria nos indicadores de saúde do município.

Introduction: early diagnosis and detection of risk factors to renal disease are difficult tasks due to the multiple related factor and because most of them are asymptomatic, leading to late diagnoses and high mobility and mortality. Objective: to analyze and correlate the parameters of evaluation and diagnosis for kidney injury and its applicability in the public and private health spheres of Rio Verde, Goiás. Method: it is a cross-field, quantitative-qualitative study. An active search was made of medical specialists and non specialists in nephrology and Urology, in the public and private health network of Rio Verde, and questionnaires were applied to them. Results: 93 physicians were approached, and 76 physicians agreed to answer the questionnaires, constituting the final sample of the study. Of these, the majority of men, with an average of between 6 and 10 years of education, 80% with a postgraduate degree and 33.3% had an exclusive relationship with the public health service. The prevalent medical evaluation applied to patients suspected of kidney injury was based on late markers, such as creatinine, serum urea, and urinalysis, and poorly on tests that detect early kidney injury such as microalbuminuria and or creatinine clearence. There was no significant difference between the propaedeutics applied in the public and private health network of Rio Verde. Conclusion: data from the present study demonstrated that the diagnosis of kidney injury is late and serves to optimize local medical conducts, which may lead to an earlier diagnosis of these lesions, which would lead to a reduction in costs and an improvement in health indicators in the municipality.

TNF-alpha expression, evaluation of collagen, and TUNEL of Matricaria recutita L. extract and triamcinolone on oral ulcer in diabetic rats.

OBJECTIVE: to evaluate the influence of Tumor Necrosis Factor alpha (TNF-α) and apoptosis in rats with DM treated with chamomile extract or triamcinolone. MATERIAL AND METHODS: Wistar male rats (210.0±4.2 g) were divided into five groups: negative control group (NCG) without diabetes; positive control group (PCG) with DM (alloxan, 45 mg/kg); and groups treated with chamomile extract (normoglycemic= NCG group and diabetic= DCG group) and with triamcinolone (TG). Traumatic ulcers were performed on all animals that received topical triamcinolone, chamomile extract or saline 12/12 hours for ten days. RESULTS: On days five and ten the animals were euthanized and the ulcers were analyzed by light microscopy, TUNEL assay, and immunohistochemically (TNF-α). The NCG (p=0.0062), PCG (p=0.0285), NCG (p=0.0041), and DCG (p<0.0001) groups were completely healed on the 10th day, however, there was no healing on the TG (p=0.5127) group. The TNF-α expression showed a significant reduction from the 5th to the 10th day in NCG (p=0.0266) and DCG (p=0.0062). In connective tissue, the TUNEL assay showed a significant reduction in the number of positive cells in NCG (p=0.0273) and CNG (p=0.0469) and in the epithelium only in CDG (p=0.0320). CONCLUSIONS: Chamomile extract can optimize the healing of traumatic oral ulcers in diabetic rats through the reduction of apoptosis in the epithelium and TNF-α expression.

Perfil bioquímico sérico de bezerros de origem leiteira aleitados com dietas líquidas alternativas / Serum biochemistry profile of dairy calves fed with alternative liquid diets

O perfil metabólico é utilizado como monitoramento rotineiro para o diagnóstico de transtornos metabólicos, deficiências nutricionais e como preventivo de transtornos subclínicos, além da pesquisa de problemas de saúde e de desempenho de um rebanho. Neste contexto, o objetivo do presente trabalho foi avaliar a influência de diferentes dietas líquidas contendo soro de queijo e colostro sobre os perfis dos metabólitos séricos de bezerros durante a fase de aleitamento. Foram utilizados 24 bezerros mestiços provenientes de rebanhos leiteiros da região, distribuídos em delineamento inteiramente casualizado com três tratamentos e oito repetições: LI = Leite integral (controle); LS = 50% Leite integral + 50% de Soro de queijo in natura; SC = 70% de Soro de queijo in natura + 30% Colostro. Semanalmente foram coletadas amostras de sangue por punção jugular externa, no período da manhã, antes do fornecimento da dieta líquida e duas horas após a ingestão desta. As concentrações dos parâmetros séricos avaliados diferiram entre os tratamentos, porém sem comprometer o desempenho dos animais. Desse modo, a utilização de soro de queijo associado ao colostro apresenta-se como forma viável de redução de custos com aleitamento de bezerros, visto que possíveis déficits causados pelas diferenças nutricionais das dietas líquidas são supridos pelos alimentos sólidos, não afetando os perfis dos metabólitos séricos relacionados ao status protéico e energético.(AU)

Metabolic profile is used as routine monitoring for the diagnosis of metabolic disorders, nutritional deficiencies, and as a preventive of subclinical disorders, in addition to research health issues and performance of a herd. In this context, the aim of this study was to evaluate the influence of different liquid diets containing whey cheese and colostrum on the serum biochemistry profile of calves. Twenty-four crossbred calves from dairy herds in the region, distributed in a completely randomized design with three treatments and eight replicates: LI = Whole milk (control); LS = 50% Whole milk + 50% cheese whey in nature; SC = 70% of cheese whey in natura + 30% Colostrum. Weekly blood samples by jugular puncture were collected in the morning, before the supply of liquid diet and two hours after eating this. The serum concentrations of the evaluated parameters differ between treatments, but without compromising animal performance. Thus, the use of whey associated with colostrum presents itself as a viable cost reduction with feeding calves, since possible nutritional deficits caused by differences in liquid diets are supplied by solid food form, not affecting the profiles of the metabolites related to serum protein and energy status.(AU)

Cytotoxic and toxicological effects of phthalimide derivatives on tumor and normal murine cells.

Eleven phthalimide derivatives were evaluated with regards to their antiproliferative activity on tumor and normal cells and possible toxic effects. Cytotoxic analyses were performed against murine tumors (Sarcoma 180 and B-16/F-10 cells) and peripheral blood mononuclear cells (PBMC) using MTT and Alamar Blue assays. Following, the investigation of cytotoxicity was executed by flow cytometry analysis and antitumoral and toxicological potential by in vivo techniques. The molecules 3b, 3c, 4 and 5 revealed in vitro cytotoxicity against Sarcoma 180, B-16/F-10 and PBMC. Since compound 4 was the most effective derivative, it was chosen to detail the mechanism of action after 24, 48 and 72 h exposure (22.5 and 45 µM). Sarcoma 180 cells treated with compound 4 showed membrane disruption, DNA fragmentation and mitochondrial depolarization in a time- and dose-dependent way. Compounds 3c, 4 and 5 (50 mg/kg/day) did not inhibit in vivo tumor growth. Compound 4-treated animals exhibited an increase in total leukocytes, lymphocytes and spleen relative weight, a decreasing in neutrophils and hyperplasia of spleen white pulp. Treated animals presented reversible histological changes. Molecule 4 had in vitro antiproliferative action possibly triggered by apoptosis, reversible toxic effects on kidneys, spleen and livers and exhibited immunostimulant properties that can be explored to attack neoplasic cells.

Thus, the use of whey associated with colostrum presents itself as a viable cost reduction with feeding calves, since possible nutritional deficits caused by differences in liquid diets are supplied by solid food form, not affecting the profiles of the metabolites related to serum protein and energy status.

Resumo: O perfil metabólico é utilizado como monitoramento rotineiro para o diagnóstico de transtornos metabólicos, deficiências nutricionais e como preventivo de transtornos subclínicos, além da pesquisa de problemas de saúde e de desempenho de um rebanho. Neste contexto, o objetivo do presente trabalho foi avaliar a influência de diferentes dietas líquidas contendo soro de queijo e colostro sobre os perfis dos metabólitos séricos de bezerros durante a fase de aleitamento. Foram utilizados 24 bezerros mestiços provenientes de rebanhos leiteiros da região, distribuídos em delineamento inteiramente casualizado com três tratamentos e oito repetições: LI = Leite integral (controle); LS = 50% Leite integral + 50% de Soro de queijo in natura; SC = 70% de Soro de queijo in natura + 30% Colostro. Semanalmente foram coletadas amostras de sangue por punção jugular externa, no período da manhã, antes do fornecimento da dieta líquida e duas horas após a ingestão desta. As concentrações dos parâmetros séricos avaliados diferiram entre os tratamentos, porém sem comprometer o desempenho dos animais. Desse modo, a utilização de soro de queijo associado ao colostro apresenta-se como forma viável de redução de custos com aleitamento de bezerros, visto que possíveis déficits causados pelas diferenças nutricionais das dietas líquidas são supridos pelos alimentos sólidos, não afetando os perfis dos metabólitos séricos relacionados ao status protéico e energético.

Effects of Bixa orellana L. seeds on hyperlipidemia.

Bixa orellana L., urucum, or urucu, a native tropical tree of Central and South American rain forests is used to treat various diseases in popular medicine. In Ceará, Northeast of Brazil, the seeds of urucum have been used for the treatment of high lipid blood levels. The present study investigated the effects of the aqueous extract from Bixa orellana seeds (AEBO) in mice with hyperlipidemia induced by tyloxapol, fructose and ethanol. In hyperlipidemia induced by Triton WR1339, 400 and 800 mg/kg AEBO reduced triglycerides (TG) serum levels at 24 h and 48 h. In the study of hypertriglyceridemia induced by fructose, AEBO in doses of 400 mg/kg and 800 mg/kg reduced TG levels by 48.2% and 48.7%, respectively. Finally, the ethanol experimental model with 400 mg/kg AEBO promoted a reduction of 33.6% of TG levels, while the 800 mg/kg concentration reduced hypertriglyceridemia in 62.2%. In conclusion, the aqueous extract of the seeds of Bixa orellana was capable of reversing the hypertriglyceridemia induced by Triton, fructose and ethanol, demonstrating a hypolipidemic effect. However, further studies are necessary to discover the precise mechanism of action.
