RESUMO
In the cropping systems that integrate the corn crop, the insertion of Crotalaria ochroleuca G. Don is predominantly intercropped. In this context, there is a need to observe herbicides that present selectivity for this sunn hemp species. The objective of this study was to evaluate the selectivity of pre and post-emergent herbicides on C. ochroleuca. Two field experiments were conducted in randomized blocks with four replications, involving the pre-emergence and post-emergence application of different herbicide treatments. For the pre-emergent ones, amicarbazone, atrazine and flumioxazin provided phytotoxicity higher than 90% and, consequently, low plant biomass. On the other hand, acetochlor and s-metolachlor did not cause phytotoxicity and did not affect the dry mass of crotalaria. In post-emergence, atrazine + mesotrione showed phytotoxicity >95%, followed by nicosulfuron and 2.4-D with phytotoxicity between 50-60%, whereas tembotrione did not cause injury to the plants. Thus, it was found that among the pre-emergent, acetochlor and s-metolachlor were selective, and for the emerging powders, only tembotrione was the most selective for all parameters analyzed.

We report the first known occurrence of Panstrongylus megistus (Burmeister, 1835) (Hemiptera, Reduviidae, Triatominae) in the Metropolitan Region of São Paulo, Brazil. In 2018, adult specimens were sent by residents to the competent authorities and, in the inspection of the property, a large focus associated with a marsupial nest was found. This finding reinforces the importance of the species in the state of São Paulo, serves as an alert for epidemiological surveillance and extends the species colonization area in the state of São Paulo.(AU)

Objectives: To evaluate the association of physical and functional measures with sarcopenia in moderate chronic obstructive pulmonary disease (COPD) and to establish cutoff points for sarcopenia screening.Methods: The study included COPD with and without sarcopenia, of both sexes who were over 50 years old. Participants were assessed for lung function, body composition, grip strength, Short Physical Performance Battery (SPPB), 5-repetition, 10-repetition and 30-s sit-to-stand tests (5STS, 10STS, and 30STS, respectively). In addition, 6-min walking test, respiratory muscular strength, and physical activity level were tested.Results: The study had 35 participants, 24 men (68.6%) and moderate COPD (51.4%). COPD-sarcopenia showed lower values in lean mass, body fat and body mass alongside lower performance in 10 and 30 STS tests, SPPB and gait speed compared to non-sarcopenic group. The cutoff points with better sensitivity and specificity to identify sarcopenia were 10.88 and 34.14 s, 15 repetitions, and 10 points in the 5STS, 10STS, 30STS, and SPPB, respectively. The comparison of the receiver operating curves evidenced no differences between the functional tests. Only 30STS and SPPB showed acceptable discriminatory power.Conclusion: Functional tests, especially 30STS and SPPB, are simple and affordable tools for screening sarcopenia in COPD with moderate obstruction.

RESUMO
O objetivo do estudo foi avaliar a disponibilidade de cálcio (Ca2+) a partir de duas formas farmacêuticas (oral e intravaginal) e o seu efeito sobre o metabolismo de ruminantes. O estudo foi realizado na fazenda experimental da Universidade Federal de Pelotas, foram estudadas 24 ovelhas lactantes, divididas de forma randomizada em 4 grupos: dispositivo tratamento (DT); dispositivo controle (DC); oral tratamento (OT); e oral controle (OC). Os animais tratados receberam formiato de cálcio e cloreto de magnésio, as avaliações foram realizadas após a administração dos tratamentos. Foi feita avaliação de cálcio total (CaT), magnésio (Mg), proteínas plasmáticas totais (PPT), aspartato aminotransferase (AST), gama glutamil transpeptidase (GGT), ureia, albumina e pH urinário, e realizado exame clínico em todos os animais. As concentrações séricas de CaT, CaI e Mg diferiram entre os grupos (P≤ 0,05), os animais dos grupos DT e DC, diferiram nas três avaliações, o grupo DT apresentou as maiores médias, sendo significativamente igual ao grupo OT. Não houve diferença nas concentrações séricas de PPT, AST, GGT, Albumina, Ureia e pH urinário. Conclui-se que a disponibilidade sanguínea de CaT, CaI e Mg é igual quando a administração de formiato de cálcio e magnésio é por via intravaginal ou por via oral, sem alterar outros parâmetros metabólicos avaliados.(AU)
The aim of the study was to evaluate the availability of calcium (Ca2+) from two pharmaceutical forms (oral and intravaginal) and its effect on the metabolism of ruminants. The study was carried out at the experimental farm of the Federal University of Pelotas. Twenty-four lactating ewes were randomly divided into 4 groups: treatment device (TD); control device (DC); oral treatment (OT); and oral control (OC). Treated animals received calcium formate and magnesium chloride, evaluations were performed after administration of the treatments. Total calcium (CaT), magnesium (Mg), total plasma proteins (PPT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), urea, albumin and urinary pH, and clinical examination were performed on all animals. Serum CaT, CaI and Mg levels differed between the groups (P≤ 0.05), the animals in the DT and DC groups differed in the three evaluations, the DT group had the highest mean values, being significantly equal to the OT group. There was no difference in the serum concentrations of PPT, AST, GGT, Albumin, Urea and urinary pH. In conclusion, the blood availability of CaT, CaI and Mg is the same when administration of calcium and magnesium formate is intravaginal or orally, without altering other metabolic parameters evaluated.(AU)

RESUMO
OBJECTIVES: The aim of this study was to analyze MMP-1 transcript levels in periodontal tissues of rats that underwent orthodontic treatment using potassium diclofenac and dexamethasone at different stages of tooth movement. SETTING AND SAMPLE POPULATION: The sample comprised of ninety male Wistar rats. MATERIAL AND METHODS: A closed nickel-titanium coil spring was used to apply a force of 50 cN to move the maxillary right first molars mesially. One group received daily doses of 0.9% saline solution, the second group received daily doses of 5 mg/kg potassium diclofenac, and the third group received daily doses of 0.5 mg/kg dexamethasone. Tooth movement was observed on days 0, 1, 3, 7, and 14. MMP-1 transcript levels were evaluated by real-time polymerase chain reaction and the results were compared between groups by three-way ANOVA, with a significance level of 0.05. RESULTS: Transcript levels increased in groups that received the coil spring treatment on all days of the experiment. MMP-1 expression was found to be decreased in groups treated with potassium diclofenac and dexamethasone compared to that in the control group, on days 1, 3, 5, and 7. CONCLUSIONS: The application of orthodontic forces significantly increased MMP-1 transcript levels. The use of anti-inflammatory drugs may have an inhibitory effect on MMP-1 expression.
