The neurological examination, developed and tested since the 1800s has provided physicians with a vital tool to rapidly assess and provide clues to many of the pathological processes lurking inside the brain and spinal cord. With the advent of magnetic resonance imaging, physicians are able to visualize the precise location of the abscess before surgical intervention. In this case report, we present a 51-year-old male with an epidural abscess with multifocal compressive myelopathy, resulting in a complicated neurological examination, making localization a diagnostic challenge. With this case, we would like to stress that complicated multifocal lesions of the cord may present with a large variation in examination findings. This patient’s neurological exam was complicated secondary to a ventrally as well as dorsally located epidural abscess with superimposed spinal shock sequelae. We would like to highlight the importance of a thorough history and the neurological examination but also mention some of its limitations. It is crucial to use clinical judgement to navigate the patient’s history, presentation, and examination to accurately diagnose and treat, particularly so in cases involving compressive myelopathies of the spinal cord.

Avocado is one of the most important crops in the world, and Mexico is the largest producer of this fruit. Several insect pests affect its production, and thrips are amongst the most important. A key step in the design of control methods is accurate species identification. Despite this, formal reports on species diversity of thrips in Mexico are very scarce. Morphological identification can sometimes be time-consuming and inconclusive. Therefore, we explored the species diversity of thrips in Mexican avocado orchards （Michoacan state） based on partial sequences of the mitochondrial gene cytochrome oxidase subunit I （COl）. Forty-four specimens were analysed, which represented approximately 8% of all individuals collected from five localities distributed in three Municipalities. All specimens were analysed using the COl marker, and specimens within the genera Frankliniella were also analysed using a marker within the D2 domain of the 28S （28SD2） nuclear ribosomal DNA. Molecular identifications were confirmed using morphological taxonomy. Overall, six genera were found （Neohydatothrips, Scirtothrips, Frankliniella, Arorathrips, Caliothrips and Leptothrips）. AII genera contained only one species, except Frankliniella, for which there were six species. Data from the two molecular markers suggest the existence of cryptic species within Mexican F. occidentalis populations.

Optimization of large-scale supply chain planning models requires the application of decomposition strategies to reduce the computational expense. Two major options are to use either spatial or temporal Lagrangean decomposition. In this paper, to further reduce the computational expense a novel decomposition scheme by products is presented. The decomposition is based on a reformulation of knapsack constraints in the problem. The new approach allows for simultaneous decomposition by products and by time periods, enabling the generation of a large number of subproblems, that can be solved by using parallel computing. The case study shows that the proposed product decomposition exhibits similar performance as the temporal decomposition, and that selecting different orders of products and aggregating the linking constraints can improve the efficiency of the algorithm.

Our contribution analyzes the process of convergence with the International Standards of Audit （ISAs）, particularly those that regulate the concept of materiality in Mexico and Colombia. Between other results, across a survey, it is demonstrated why the effective use of the factors that emerge of his qualitative slope can favor the quality of the financial information that publish the audited companies, the usefulness and the comprehensibility of the report of opinion. In general, the reliability, transparency, and relevancy of the financial statements will meet potentially favored with the strict application of these major and better normative instruments.

In this study Essential oils were used with cumin, cloves, cinnamon, laurel and anis to determine Minimum Inhibitory Concentration (MIC) against Mycobacterium tuberculosis strains. The MICs were determined on M. tuberculosis H37Rv sensitive to all five firstline antituberculosis drugs (streptomycin, isoniazid, rifampicin, ethambutol and pirazinamide), two H37-Rv (CH-8 and CH-15) isoniazid-resistant, two H37Rv (CH-07 and CH-09) rifampicin-resistant, two H37Rv (CH-03 and CH-06) streptomycin-resistant, and two H37Rv (CH-09 and CH-10) ethambutol-resistant using the microplate alamar blue assay. The results obtained showed that the cumin and cinnamon essential oils showed a MIC of 12.5 μg/ml against reference strain H37Rv. The five essential oils used in this study were effective against the isoniazid-resistant variant of H37RV with MIC values in the range 12.5-100 μg/ml, the most potent being the cumin and cin-namon (MIC = 12.5). Similar results were obtained against rifampicin-resistant variant of H37RV with MIC values in the range 12.5-100 μg/ml;the most active ones?in this case were the essential oils of cumin and cloves. The essential oils of anis and laurel were active with MIC value to 100 μg/ml. Clove, cumin, and cinnamon essential oils were active against all strains utilized in this study, with MIC values in the range 6.25 μg/ml to 25 μg/ml.
