The myth of the Flood is one of the oldest stories in mankind history. Its symbolic content expresses the human experience in relation to punishment and the end of a cycle. It implies a sense of guilt, loss of what is essential, which is experienced as an approach to death and the concept of renewal or rebirth. The short stories “Monólogo de Isabel viendo llover en Macondo”, by Gabriel García Márquez (Colombia, 1927) and “Vicente” by Miguel Torga (Portugal, 1907-1995), go to this myth. In both cases, it is interesting and revealing that two top writers take the myth to represent the world they live in, despite their cultural differences related to the latitude from which they wrote their stories. They do this to reflect on it and confront it. This analysis incorporates the theoretical perspective of Pimentel (1998) who says that a character is an effect of meaning achieved through discursive and narrative strategies. That is, each chosen element for the purpose of shaping a story has a certain intention and uses symbolic and cultural references. Besides that, it sets up reading contract with the reader. Therefore, this paper analyzes the approaches that these two writers make to the Flood story. It focuses on the coincidence that in creating the main characters in both stories (Isabel and Vicente), the writers chose their names carefully. First, it states that they both went to similar cultural-symbolic referents. And second, it says that in both stories, nature has a fundamental role and it is seen as a facilitator of the return to origin and that it symbolizes the beginning of life. Both stories offer a variation of the myth of the Flood as in the Judeo-Christian tradition, but the two writers go to this myth with different intentionality. Torga goes to it to remake it and while he writes it, he confronts the original story. In the other hand, Garcia Marquez goes to the myth with the intention of reflecting on the cyclical nature of humankind history.

Bilateral posterior communicating (pComm) artery aneurysms represent only 2% of mirror intracranial aneurysms. Usually, these are surgically approached through bilateral craniotomies for clipping. We present the case of a 50-year-old female presenting with headache and horizontal diplopia. Neurological examination revealed a left oculomotor palsy, with no other neurological deficits. Imaging studies revealed bilateral aneurysmatic lesions in both internal carotid arteries (ICA). A conventional left pterional approach was planned in order to treat the symptomatic aneurysm, and, if deemed feasible, a contralateral clipping through the same approach. The procedure was performed in a hybrid operating room (HOR), performing an intraoperative digital subtraction angiography (DSA) and roadmapping assistance during dissection and clipping. Transoperatively, a post-fixed optic chiasm was identified, with a wide interoptic space, which allowed us to perform the contralateral clipping through a unilateral approach. This technique for clipping bilateral pComm aneurysms can be performed when the proper anatomical features are met.

The nutritional quality, sensory attributes,polyphenols and acetogenins content in yoghurt and frozendessert formulated with soursop pulp were investigated. The addition of soursop pulp to yoghurt and frozen dessertimproved the sensory attributes and the nutritional qualityof soursop dairy products resulting in a composition of 0.92and 2.17% of dietary fiber, 11.25 and 9.84 mg/100 g ofvitamin C as well as 243.02 and 490.98 mg/100 g of totalpolyphenols, respectively. Acetogenins were extractedfrom both dairy products using maceration, sonication,microwave and Soxhlet. Sonication showed to be faster andsafer than the other methods for acetogenins extraction. Higher annonacin (an acetogenin) content was found inyoghurt (38 ng/g) than in frozen dessert (15 ng/g). Thequantification of bioactive compounds implied thenutraceutical properties to yoghurt and ice cream whenthey are added with soursop pulp. The results are useful forthe consumers seeking healthier foods.

Thrombectomy procedures following intra-aneurysmatic lesions are extremely rare, and few cases have been reported. This article describes a microsurgical intra-aneurysmatic thrombectomy (MIaT) for a distal anterior cerebral artery (DACA) aneurysm. We present the case of a 48-year-old female that was admitted to the emergency room, showing neurologic deterioration with focal deficits. A computed tomography angiography (CTA) scan revealed an aneurysm located in the distal segment of the left anterior cerebral artery. During the surgical procedure, after clipping, a wellformed clot was visualized through the aneurysm’s wall obstructing the left DACA flow. We proceeded to open the aneurysm’s dome to remove the thrombus and clip the aneurysm neck, re-establishing the flow of the left DACA.Intra-aneurysmatic thrombosis can occur as a complication during clipping, obstructing the distal flow of vital arteries and causing fatal results in the patient’s postoperative status. MIaT is a good technique for restoring the flow of the affected vessel and allows a secure aneurysm clipping after thrombus removal.

Dear Editor, Lipoprotein lipase (LPL) deficiency is a rare disease characterized by severe hypertriglyceridemia due to mutations in the LPL gene. It shows an autosomal recessive inheritance pattern and has a general prevalence of 1:1,000,000 [1]. Patients typically present abdominal pain, hemorrhage, failure to thrive, jaundice, eruptive xanthomas, lipemia retinalis, neurological complications, hepatosplenomegaly, and life-threatening pancreatitis [2]. The LPL gene is located on chromosomal band 8p22, contains 10 exons, and codes for a 475-amino acid protein that is active only in its dimeric form. The LPL protein has two functions in lipid metabolism: it hydrolyzes triglycerides and functions as a ligand [3]. The aim of this work is to describe the biochemical, clinical, and molecular features of a Mexican girl with LPL deficiency.

This study characterized Clavispora lusitaniae strains isolatedfrom different stages of the processing and early fermentationof a henequen (Agave fourcroydes) spirit produced inYucatan, Mexico using a molecular technique. Sixteen strainsidentified based on morphological features, obtained fromdifferent substrates, were typed molecularly. Nine differentversions of the divergent D1/D2 domain of the large-subunitribosomal DNA sequence were identified among theC. lusitaniae strains. The greatest degree of polymorphismwas found in the 90-bp structural motif of the D2 domain. The MSP-PCR technique was able to differentiate 100% ofthe isolates. This study provides significant insight into thegenetic diversity of the mycobiota present during the henequenfermentation process, especially that of C. lusitaniae,for which only a few studies in plants have been published. The applied MSP-PCR markers were very efficient in revealingpolymorphisms between isolates of this species.

Mexico is one of the five largest producers of papaya worldwide, but losses caused by pathogens, mainly fungus, at the pre- and post-harvest stages are often more than 50% of the crop. Papaya anthracnose, caused by three different species of the Colletotrichum genus in Mexico, occupies a preponderant place in this problem. Although two of these species, C. gloeosporiodes and C. truncatum, have been characterized morphologically and genotypically, this has not occurred with C. magnum, the third species involved, about which there is very little information. Because of this, it is vital to know its genetic characterization, much more so considering that the studies carried out on the other two species reveal a wide genetic diversity, differences in pathogenicity and in the response to fungicides of the different strains characterized. In this work, Colletotrichum spp. isolates were collected at different papaya orchards in the south-southeast of Mexico. C. magnum isolates identified by species-specific primers were characterized by morphological and molecular approaches. Differences in colony characteristics resulted in five morphological groups. AP-PCR, DAMD and ISSR markers were found to be very efficient for revealing the interspecific variability of this species. The high genetic variability found in the accessions of C. magnum was linked to the geographical area where they were collected. Isolates from Chiapas State were the most variable, showing point mutations in the ITS1- ITS2 region. These results will enable a better phytosanitary management of anthracnose in papaya in this region of Mexico.

In the present study, we evaluated new sources of plant proteases from fruits of Bromelia karatas (BK) and Bromelia pinguin (BP) to obtain antioxidant hydrolyzates/bioactive peptides (BPs) derived from chicken by-products (CH) and fish by-products (FH). The profile of the peptides was identified by reverse-phase high-resolution liquid chromatography (RP-HPLC) and the size weight distribution by molecular exclusion chromatography (SEC). The hydrolysates obtained with BK in both sources of by-products showed greater antioxidant capacity compared to those obtained with BP, presenting similar or higher values when compared to a commercial plant enzyme. The use of new sources of plant proteases allowed to obtain hydrolysates of hydrophilic character with a high percentage (> 50%) of peptides with molecular weights < 17.5 kDa from chicken and fish by-products. Therefore, based on the results obtained in antioxidant capacity it is possible to consider the hydrolysates as potential ingredients, food additives, and pharmaceutical products.

Objectives: Airway management in patients with panfacial trauma is complicated. In addition to involving facial lesions, such trauma compromises the airway, and the use of intermaxillary fixation makes it difficult to secure ventilation by usual approaches (nasotracheal or endotracheal intubation). Submental airway derivation is an alternative to tracheostomy and nasotracheal intubation, allowing a permeable airway with minimal complications in complex patients. Materials and Methods: This is a descriptive, retrospective study based on a review of medical records of all patients with facial trauma from January 2003 to May 2015. In total, 31 patients with complex factures requiring submental airway derivation were included. No complications such as bleeding, infection, vascular, glandular, or nervous lesions were presented in any of the patients. Results: The use of submental airway derivation is a simple, safe, and easy method to ensure airway management. Moreover, it allows an easier reconstruction. Conclusion: Based on these results, we concluded that, if the relevant steps are followed, the use of submental intubation in the treatment of patients with complex facial trauma is a safe and effective option.
