ABSTRACT Understanding weed emergence and development aspects is essential in decision-making for management strategies. The study evaluated the effects of different sowing depths and light intensities on the emergence and development of the weeds Sida rhombifolia and Senna obtusifolia under field conditions. Each species constituted an experiment, and the experimental design used was completely randomized, with four replications. The treatments were arranged in a 6 x 4 factorial scheme, with the first factor corresponding to the six sowing depths (0.5; 1.0; 2.0; 4.0; 8.0, and 12.0 cm) and the second at four light intensities (100%, 70%, 50%, and 30% of sunlight). The seedling emergence was evaluated daily to obtain the emergence and emergence speed index. The height, time to floral induction, and dry matter of plants at flowering were also evaluated. When submitted to different levels of shading, S. rhombifolia seedlings emerge up to 12.0 cm deep. S. obtusifolia seedlings emerge at all sowing depths, even when subjected to different solar radiation intensities. Seedlings of S. rhombifolia and S. obtusifolia emerge less and slower in sowings between 8.0 and 12.0 cm depth and develop better under full sunlight in sowings between 1.0 and 4.0 cm depth. Therefore, greater depths delay the development of both species, which is important information for managing these weeds.

RESUMO Compreender os aspectos de emergência e desenvolvimento de plantas daninhas é essencial na tomada de decisão para estratégias de manejo. Neste trabalho foram avaliados em condições de campo, os efeitos de diferentes profundidades de semeadura e intensidades luminosas na emergência e no desenvolvimento das plantas daninhas Sida rhombifolia e Senna obtusifolia. Cada espécie constituiu um experimento e o delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições. Os tratamentos foram dispostos em esquema fatorial 6 x 4, sendo o primeiro fator correspondente as seis profundidades de semeadura (0,5; 1,0; 2,0; 4,0; 8,0 e 12,0 cm) e o segundo a quatro intensidades luminosas (100%, 70%, 50% e 30% da luz solar). Avaliou-se diariamente a emergência das plântulas para obtenção da emergência e do índice de velocidade de emergência. A altura, o tempo até a indução floral e a matéria seca das plantas no florescimento também foram avaliadas. Quando submetidas a diferentes níveis de sombreamento as plântulas de S. rhombifolia emergem em até 12,0 cm de profundidade. As plântulas de S. obtusifolia emergem em todas as profundidades de semeadura, mesmo quando submetidas a diferentes intensidades de radiação solar. As plântulas das espécies S. rhombifolia e S. obtusifolia emergem menos e em menor velocidade em semeaduras entre 8,0 e 12,0 cm de profundidade e se desenvolvem melhor em condições de luz solar plena em semeaduras entre 1,0 e 4,0 cm de profundidade. Portanto, maiores profundidades atrasam o desenvolvimento de ambas as espécies, sendo uma importante informação para o manejo dessas plantas daninhas.

Abstract It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list of amphibians and reptiles from two localities in the São Francisco-Gurguéia region in Piauí. Additionally, we compare the species composition between nine areas within the Caatinga, which were sampled using standardized methods over the past ten years, to examine broader spatial patterns of community composition. To survey reptiles and amphibians, we employed similar methods and sampling efforts in two areas within the Serra das Confusões National Park (SCNP) region. Our surveys recorded a total of 73 species of amphibians and reptiles, of which 24 are new distribution records for the SCNP region. Consequently, our findings increase the known herpetofauna in the region to 94 species. Despite their proximity, the two sites in the SCNP region exhibited only 42% similarity in species composition, and they differed significantly from other areas within the Caatinga. Furthermore, even the closer Caatinga areas presented differences in species composition, highlighting the necessity to evaluate biodiversity across the landscape and contribute to understanding biogeographic patterns.

Resumo É repetidamente enfatizada a necessidade de caracterizar a biodiversidade vivente em ecossistemas tropicais. No entanto, os estudos de inventário ainda estão progredindo lentamente em ecossistemas secos, levando à subestimação de sua verdadeira biodiversidade e dificultando os esforços de conservação. Neste estudo, apresentamos dados primários e secundários, juntamente com uma lista atualizada de anfíbios e répteis de duas localidades na região de São Francisco-Gurguéia, do Piauí. Além disso, comparamos a composição de espécies entre nove áreas dentro da Caatinga, que foram amostradas usando métodos padronizados nos últimos dez anos, para examinar padrões espaciais mais amplos de composição da comunidade. Para estudar répteis e anfíbios, utilizamos métodos e esforços de amostragem semelhantes em duas áreas na região do Parque Nacional da Serra das Confusões (PNSC). Nossos levantamentos registraram um total de 73 espécies de anfíbios e répteis, das quais 24 são novos registros de distribuição para a região do PNSC. Consequentemente, nossos resultados aumentam a herpetofauna conhecida na região para 94 espécies. Apesar da proximidade, os dois locais na região do PNSC exibiram apenas 42% de similaridade na composição de espécies e diferiram significativamente de outras áreas dentro da Caatinga. Mesmo áreas mais próximas da Caatinga apresentaram diferenças na composição de espécies, destacando a necessidade de avaliar a biodiversidade em toda a paisagem e contribuir para a compreensão de padrões biogeográficos.

RESUMO Informações sobre o impacto dos herbicidas no solo baseado no crescimento de espécies bioindicadoras são extremamente úteis no desenvolvimento de estratégias de gerenciamento de culturas. O objetivo deste estudo foi avaliar o potencial de lixiviação do S-metolachlor em precipitações pluviométricas naturais em um Latossolo (Oxisol) de textura média, através do uso de plantas bioindicadoras. Adotou-se o delineamento experimental inteiramente casualizado, com quatro repetições e os tratamentos dispostos em esquema fatorial 3 × 8 [três índices de precipitação ocorrida no ambiente antes da coleta das amostras (50, 91 e 131 mm) e oito profundidades no perfil do solo (0-0,03; 0,03-0,06; 0,06-0,09; 0,09-0,12; 0,12-0,15; 0,15-0,20; 0,20-0,25; 0,25-0,30 m)]. Colunas de PVC foram introduzidas mantendo a integridade original do solo durante a amostragem, após o acúmulo de precipitação natural estipulado. As colunas foram separadas por seção longitudinal para a semeadura das espécies bioindicadoras (pepino, alface, capim-marmelada e sorgo). Os sintomas de fitotoxicidade nas plantas bioindicadoras foram avaliados adotando-se a escala visual de fitotoxicidade entre 0 e 100%, aos 5, 7, 9 e 11 dias após a semeadura. As respostas das espécies bioindicadoras ao efeito residual do S-metolachlor foram variáveis e dependeram da precipitação. Em um Latossolo de textura média, as maiores concentrações de S-metolachlor ocorrem em profundidades que variam entre 0 e 0,06 m. A profundidade máxima de lixiviação detectada foi de 0,12-0,15 m com 131 mm de precipitação. Por apresentar sintomas de fitotoxicidade em maiores profundidades, o pepino foi a espécie mais sensível à presença de S-metolachlor em Latossolo de textura média.

ABSTRACT Information about the impact of herbicides in the soil based on the growth of bioindicator species is extremely useful in developing crop management strategies. Therefore, this study aims to evaluate the leaching potential of the herbicide S-metolachlor under different natural precipitations in medium-textured Oxisol using bioindicator plants. A completely randomized experimental design was adopted, with four replicates and treatments arranged in a 3 × 8 factorial scheme [three indexes of precipitation occurred in the environment before the collection of the samples (50, 91, and 131 mm) and eight depths in the soil profile (0-0.03; 0.03-0.06; 0.06-0.09; 0.09-0.12; 0.12-0.15; 0.15-0.20; 0.20-0.25; 0.25-0.30 m)]. PVC columns were used, maintaining the original soil integrity during sampling after accumulating the stipulated natural precipitation. Longitudinal sections separated the columns to sow the bioindicator species (cucumber, lettuce, Alexander grass, and sorghum). The phytotoxicity symptoms of bioindicator plants were evaluated, adopting a phytotoxicity visual scale between 0 and 100%, at 5, 7, 9, and 11 days after seeding. The responses of the bioindicator species to the residual effect of the herbicide S-metolachlor were variable and depended on the rainfall level. Generally, in a medium-textured Oxisol, the higher values of concentration of S-metolachlor occurs in depths ranging between 0 and 0.06 m. The maximum leaching depth detected was 0.12-0.15 m with 131 mm of precipitation. Cucumber was the most sensitive species to the presence of S-metolachlor in an Oxisol of medium-texture since it presents symptoms of phytotoxicity at higher depths.

RESUMO A presença de plantas daninhas como consequência da degradação de pastagens é um dos principais problemas da pecuária em todo o mundo. Assim, o conhecimento dos aspectos de interferência e do período apropriado para o manejo dessas espécies é essencial para a decisão de aplicar uma determinada medida de controle. Este estudo teve como objetivo estudar a interferência de plantas daninhas sobre os componentes morfoestruturais e na qualidade nutricional do capim Marandu em condições de renovação ou manutenção de pastagem. Os experimentos foram conduzidos em delineamento experimental de blocos ao acaso, com quatro repetições, sendo os tratamentos constituídos por oito períodos crescentes de convivência entre o capim Marandu e as plantas daninhas (0, 15, 30, 45, 60, 75, 90, e 120 dias). A caracterização da gramínea forrageira foi realizada ao final do período de condução do experimento, que correspondeu a 120 dias de convivência, obtendo os principais componentes morfoestruturais e nutricionais da forragem. As plantas daninhas interferem na qualidade morfoestrutural e nutricional de áreas de pastagem com capim Marandu que passam pelo processo de renovação ou manutenção. A digestibilidade in vitro da matéria orgânica do capim Marandu é negativamente influenciada pela presença de plantas daninhas, sugerindo que medidas de controle em áreas de renovação ou manutenção de pastagens devem ser adotadas até 24 e 18 dias de convivência em comum, respectivamente.

ABSTRACT The presence of weeds as a consequence of pasture degradation is one of the main problems facing livestock worldwide. Thus, knowing the interference aspects and the appropriate time for weed management is essential for applying a particular control measure. This research aimed to study the weed interference on the morphostructural and nutritional quality of the Marandu palisade grass in conditions of renewal or maintenance of pasture. The experiments were conducted in a randomized block design, with four replicates and treatments consisted of eight growth periods of coexistence between Marandu palisade grass and weeds (0, 15, 30, 45, 60, 75, 90, and 120 days). Forage grass was characterized at the end of the experimental period, corresponding to 120 days of coexistence, and the main morphostructural and nutritional components were determined. Under the renewal or maintenance process, the weeds interfere in the morphostructural and nutritional quality of pasture areas with Marandu palisade grass. In vitro organic matter digestibility of Marandu palisade grass is negatively influenced by weeds, suggesting that control measures for renewal or maintenance areas should be adopted within 24 and 18 days of coexistence, respectively.

ABSTRACT Auxin-based herbicides, such as 2,4-dichlorophenoxyacetic acid (2,4-D), are lethal to plants at higher doses, but can enhance plant growth at nontoxic concentrations. The stimulating effect of low doses of a substance considered toxic is known as hormesis. This study used dose-response curves to assess the hormesis effect of low doses of 2,4-D choline salt herbicide on soybean (Glycine max (L.) Merr.) biometric variables with distinct growth habits at different phenological stages. A completely randomized experimental design with seven replicates was used, and the treatments consisted of six fractions of the average dose indicated on the label of 2,4-D choline salt formulation: 0 (control), 0.068, 0.684, 6.84, 68.4 and 684 g ae ha-1 applied at the plant’s phenological stages second node with fully developed leaves (V2) or fifth node with fully developed leaves (V5). The plants were assessed for their main biometric parameters. The results were analyzed by ANOVA and, when significant, the hormesis model was tested. The maximum effect of hormesis on the main biometric parameters of soybean plants was estimated for doses between 0.20 and 36.01 g ae ha-1 of the herbicide and varies depending on the evaluated phenological stage of the plants. Low doses of 2,4-D choline salt herbicide may increase shoots, roots and total DM when applied at stages V2 and V5 of soybean with determinate growth habit and V2 of indeterminate growth habit. There was no adjustment of the hormesis model for the soybean plant with indeterminate growth habit at stage V5.

RESUMO Operações sucessivas de corte são os principais custos na manutenção de gramados. O dispêndio com os cortes leva à busca por alternativas para o manejo mecânico. O presente estudo teve por objetivo estudar os efeitos de doses do herbicida imazapic aplicado isolado ou em associação com imazapyr, como regulador de crescimento das gramas Tifton 419 e Esmeralda. Adotou-se o delineamento experimental de blocos casualizados, com quatro repetições e os tratamentos constituíram de quatro doses do herbicida imazapic isolado (35; 70; 105 e 140 g i.a. ha-1) e três doses da associação de imazapic + imazapyr (7,875 + 2,625; 15,57 + 5,25 e 23,625 + 7,875 g i.a. ha-1) em duas aplicações sequenciais para ambas as espécies. Avaliaram-se os sintomas visuais de injúria, a altura do dossel, a altura e o número de inflorescências e a matéria seca total das aparas. As aplicações de imazapic isolado ou em associação com imazapyr foram efetivas na redução de todas as variáveis morfológicas da grama Tifton 419. O imazapic aplicado isolado ou associado ao imazapyr proporcionou controle satisfatório do crescimento e da quantidade de matéria seca das aparas da grama Esmeralda, no entanto, algumas doses desse herbicida aumentaram o número de inflorescências presentes nos gramados.

ABSTRACT Successive mowings are the major maintenance cost of lawns. These costs have led to the search for alternatives to mechanical management. This study aimed to determine the effects of imazapic herbicide doses applied alone or combined with imazapyr as a growth regulator of Tifton 419 and Zoysia grasses. The experimental design was randomized blocks with four replicates, and the treatments consisted of four doses of herbicide imazapic applied alone (35; 70; 105 and 140 g a.i. ha-1) and three doses of imazapic + imazapyr mixture (7.875 + 2.625; 15.57 + 5.25 and 23.625 + 7.875 g a.i. ha-1) in two sequential applications on both grass lawns. Visible injury symptoms, canopy height, height and number of inflorescences, and total dry matter of clippings were determined. Applications of imazapic alone or combined with imazapyr effectively reduced all morphological variables of Tifton 419 grass. Imazapic applied alone or mixed with imazapyr provided adequate control of growth and quantity of dry matter of Zoysia grass clippings. Still, with some application doses of this herbicide, the number of inflorescences present in the lawns increased.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Abstract Spatial heterogeneity of vegetation is considered to be one of the most important factors that can influence species richness in a region and, therefore, an important driver for species diversity. Here, we investigate how squamate diversity varies throughout a heterogeneous area in southeastern Atlantic Forest. Our sampling site corresponded to a mosaic of forest and open fields in Curucutu nucleus, Serra do Mar State Park, São Paulo State, Southeastern Brazil. Species diversity varied throughout the mosaic in terms of species composition and relative abundance, with some species being clearly associated with a particular physiognomy. However, a decrease is observed in species richness in forest, after the rarefaction method is applied, showing that when the abundance effect is excluded, only species composition differed between physiognomies. On the other hand, both space and environmental heterogeneity were associated with diversity and distribution of squamates. Our results emphasize the importance of environmental heterogeneity, as well as the influence of the spatial location of the sample units, in structuring squamate diversity in a highland assemblage from the Atlantic Forest.

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

Abstract Background: Talquezal (Paspalum virgatum L.) has become one of the main pasture weeds due to its association with the Urochloa brizantha death syndrome, a disease that causes the progressive death of clumps of susceptible grasses in patches, which leads to weed colonization and pasture degradation. Understanding the weed emergence pattern is essential in decision making for management strategies. Objective: Thus, this study aimed to evaluate the emergence pattern of talquezal seedlings according to its origin and the amount of straw covering the soil. Methods: The experiment was carried out in a greenhouse in a completely randomized design, with six replications and treatments arranged in an 8 × 3 factorial scheme with eight amounts of Urochloa brizantha straw covering the seeds (0, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0, and 10.0 ton ha-1) and three collection sites (Rondonópolis, Redenção, and Cacoal). The effect of the origin and amount of straw was evaluated by the percentage of emergence, relative emergence frequency, mean emergence time, emergence synchrony, and emergence speed index of seedlings obtained over 35 days after sowing. Results: Talquezal seeds showed high seedling emergence vigor regardless of their origin under amounts of straw lower than 4.0 ton ha-1. Conclusions: The result suggests that the amounts of U. brizantha straw higher than 4.0 ton ha-1 on the soil surface, the lower is the percentage of Talquezal seedling emergence.

RESUMO O cobre (Cu) é um micronutriente essencial aos vegetais, mas em excesso torna-se fitotóxico para as plantas. Nesse contexto, o objetivo deste trabalho foi avaliar o crescimento e as respostas fisiológicas de espécies arbóreas expostas a diferentes concentrações de cobre no solo. Foram realizados três experimentos, sendo um para cada espécie florestal em estudo: Myroxylon peruiferum (Óleo Bálsamo), Hymenaea courbaril (Jatobá) e Peltophorum dubium (Canafístula), com as mesmas doses de cobre (0, 50, 100, 200 e 400 mg kg-1). O delineamento para os experimentos foi em blocos casualizados (DBC) com cinco concentrações de Cu e quatro repetições. As plantas foram cultivadas em substrato de solo acondicionados em vasos de 8 dm3 e mantidas em casa-de-vegetação por 90 dias. Foram avaliadas medidas biométricas, clorofila, enzimas antioxidantes e o teor de Cu nos tecidos. O Cu não influenciou no crescimento vegetativo das espécies estudadas. O teor de clorofila "a" foi reduzido com o aumento do Cu no solo. H. courbaril apresentou 56 a 92% do Cu retido nas raízes, ocorrendo o mesmo comportamento para P. dubium (77-91%) e M. peruiferum (19-64%). Nas três espécies em estudo houve bioacumulação do Cu nas raízes, possivelmente como estratégia de tolerância ao metal, preservando os tecidos mais ativos e a maquinaria fotossintética. A translocação do Cu das raízes para a parte aérea foi muito restrita em todas as espécies. Este comportamento associado com o aumento da atividade de algumas enzimas do sistema antioxidante nas plantas pode indicar o potencial fitorremediador das espécies estudadas.

ABSTRACT Copper (Cu) is an essential micronutrient for plants. However, when in excess, it becomes phytotoxic. In this context, the objective of this study was to evaluate the growth and physiological responses of tree species exposed to different copper concentrations in the soil. Three experiments were carried out, one for each forest species under study: Myroxylon peruiferum ("Óleo Bálsamo"), Hymenaea courbaril ("Jatobá") and Peltophorum dubium ("Canafístula"), with the same doses of copper (0, 50, 100, 200 and 400 mg kg-1). The experimental design was in randomized blocks (DBC), with five copper concentrations and four replicates. The plants were grown on soil substrate packed in 8-dm3 pots and kept in a greenhouse for 90 days. Biometric measurements, chlorophyll, antioxidant enzymes and copper content in tissues were evaluated. Copper did not influence the vegetative growth of the species studied. The content of chlorophyll "a" was reduced with increasing copper concentrations in the soil. H. courbaril had 56 to 92% copper retained in the roots, and the same behavior was observed for P. dubium (77-91%) and M. peruiferum (19-64%). In the three species studied, there was copper bioaccumulation, mainly in the roots, possibly as a metal tolerance strategy, preserving the most active tissues and the photosynthetic machinery. Cu translocation from roots to shoot was very restricted in all species. This behavior, associated with the increase in the activity of some antioxidant enzymes in plants, may indicate the phytoremediation potential of the studied species.

ABSTRACT The germinative, Sertoli and Leydig cells of two caviomorph rodents (Cavia porcellus and Dasyprocta agouti) were counted as well as the estimation of the total volume of the testis and the total volume of seminiferous tubules and interstitium in prepubertal, pubertal and adult animals. The number of spermatogonia, spermatocytes and spermatids cells increased during the pubertal phase in both rodents, notably the spermatid cells. The spermatocyte and spermatid slightly decreased in the adult of both rodents, but the increment in spermatogonia cells number was seen, mainly in cutias. The number of Sertoli cells increased in pubertal rodents, but in the adult the number reduced. Substantial number of Leydig cells was counted in pubertal and adult guinea pigs. In cutias, the number of Leydig cells increased in pubertal phase and decline in adults. The design-based stereological method has proven to be unbiased and reliable to be applied in reproduction studies.

The aim this research is to develop a HS-SPME/GC-MS method to analyze the carbaryl in blood plasma samples of the rural workers, who live round the perimeter of Chapada do Apodi-CE. This was achieved by chromatographic signal of the 1-naftol, degradation product of carbaryl with the intention of evaluating the degree of exposure of the workers to pesticides, causing chromosome abnormalities as already evidence in appropriate literature. Three different types of covered SPME fibers were tested and a full factorial design with central point in two levels. The variables optimized were temperature and ionic strength and temperature was the response in the design. Study was undertaken to determinate the equilibrium time. The thermal degradation of carbaryl in SPME headspace was analyzed by 1H-NMR. Proposed method achieved low limits of detection and quantification (1.5 and 5 ng mL-1, respectively) with good precision and accuracy, using the method of weighted least squares. However, the proposed method can be considered a good alternative way of monitoring carbaryl in blood plasma by analytical signal of 1-naftol. None of the plasma analyzed presented a concentration of 1-naftol compound higher than limit of detection of the method proposed here.
