Preventive and curative activity of postharvest treatments with chitosan nanoparticles (CS) and chitosan biocomposites loaded with pepper tree essential oil (CS-PEO) against anthracnose were evaluated on Avocado (Persea americana) cv. Hass artificially inoculated in rind wounds. After 10 days of storage significant preventive and curative activity against Colletotrichum gloeosporioides was observed with the absence of internal damage by applying CS and CS-PEO. Quality parameters like water losses and firmness changes were assessed on fruit treated. CS and CS-PEO were effective to reduce water losses and firmness losses.

The Périgord black truffle (Tuber melanosporum) is an edible fungus and among the most expensive foods worldwide. It is the basis of a multimillion-dollar bio-business. Truffle farming does not exist in Mexico, and no formal studies have been conducted on its culture. This report describes the mycorrhizal synthesis (i.e., artificial union of fungus with host) of T. melanosporum with oak species native to Mexico (Quercus polymorpha, Q. fusiformis, and Q. canbyi). The mycorrhizal association was successful in Q. polymorpha and Q. fusiformis, as confirmed morphologically and using T. melanosporum molecular primers (ITSML/ITS4LNG). The effect of the ectomycorrhizal fungus on host growth (stem diameter) was statistically significant. Illustrations of the study are presented.

Structural Health Monitoring (SHM) researchers have identified Augmented Reality (AR) as a new technology that can assist inspections. Post-seismic structural inspections are conducted to evaluate the safety level of the damaged structures. Quantification of nearby structural changes over short-term and long-term periods can provide building inspectors with information to improve their safety. This paper proposes a Time Machine Measure (TMM) application based on an Augmented Reality (AR) Head-Mounted-Device (HMD) platform. The primary function of TMM is to restore the saved meshes of a past environment and overlay them onto the real environment so that inspectors can intuitively measure dynamic structural deformation and other environmental movements. The proposed TMM application was verified by demo experiments simulating a real inspection environment.

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.

지난 몇 년간, 한국 관광객의 국제 관광지 유입은 특히 아시아가 아닌 국가에서 크게 증가했다. 그러나 멕시코는 여전히 한국 관광객에게 인기있는 관광지가 아니다. 이러한 현상의 제고와 인식의 개선을 위해 본 연구를 진행하였다. 이 논문은 켈러의 브랜드 에퀴티 모델을 사용하여 한국인과 멕시코인이 가지는 일반적인 브랜드 이미지를 비교하고 분석하였다. 한국 관광객이 멕시코라는 나라에 가지는 국가 브랜드와 관광지로서의 수준을 파악하여 연구의 가치를 더하였다. 이 연구의 결과는 후속적으로 이루어질 멕시코의 국가 브랜드 홍보를 위한 새로운 접근법이 될 것이며, 기획, 창작, 디자인 및 개발 연구에 가치있는 초석이 될 것이다.

The aim of this study was to characterize potential fungal species affecting mangrove species in Mexico. The phytopathogens were identified based on morphological and molecular characteristics using internal transcribed spacer (ITS1/ITS4) primers then sequenced and compared with the other related sequences in GenBank (NCBI). Three fungal species were identified as Colletotrichum queenslandicum (Weir and Johnst, 2012) from black mangrove (Avicennia germinans); Colletotrichum ti (Weir and Johnst, 2012) from white mangrove (Laguncularia racemosa) and buttonwood mangrove (Conocarpus erectus); Fusarium equiseti (Corda) from red mangrove (Rhizophora mangle). In addition, C. ti and F. equiseti were identified from mango Mangifera indica L. sampled close by the mangrove area. This study provides first evidence of anthracnose on four mangrove species caused by Colletotrichum and Fusarium species in the "Términos" coastal lagoon in Campeche State southern Mexico. This is the first time that C. queenslandicum and C. ti are reported in Mexico. F. equiseti has not been reported affecting M. indica and R. mangle until the present work. Little is known regarding fungal diseases affecting mangroves in Mexico. These ecosystems are protected by Mexican laws and may be threatened by these pathogenic fungus. This is the first report of the effect of Trichoderma harzianum TRICHO-SIN as an effective biological control against of Colletotrichum and Fusarium species.

미국-멕시코 국경지대는 멕시코의 마킬라도라 산업에 대한 세계 다국적기업들의 투자로 인해 고용확대, 인구증가, 산업발달이 이루어지고, 특히 국경지대의 쌍둥이 도시들은 많은 사회경제적 변화를 겪게 되었다. 1965년에 시작된 멕시코의 마킬라도라 프로그램은 외국기업의 투자를 유치하기 위한 보세가공 산업정책이었는데, 2006년부터는 멕시코인 소유의 수출기업을 포함하는 IMMEX 프로그램으로 대체되었다. 마킬라도라를 포함한 IMMEX 기업들은 2007년 이후 업체수는 큰 변화가 없는 반면 업체당 종사자수는 점차 대형화하고 있다. 업종별로 보면 자동차, 항공기와 관련된 운송장비제조업이 가장 크게 성장하였으며, 과거 마킬라도라 산업에서 큰 비중을 차지하던 섬유·직물·의류제조업은 상대적으로 침체의 길을 걷고 있다. IMMEX의 비제조업 분야에서는 종사자수와 해외매출액에 있어서 농업의 비중이 압도적이다. IMMEX 기업들의 지역적 분포에서는 티화나와 후아레스가 압도적으로 높은 비중을 차지하고 있다.

The effect of PHAR-DBH-Me, a cannabinoid receptor agonist, on different cardiovascular responses in adult male rats was analyzed. The blood pressure was measured directly and indirectly. The coronary flow was measured by Langendorff preparation, and vasomotor responses induced by PHAR-DBH-Me in aortic rings precontracted with phenylephrine (PHEN) were analyzed. The intravenous injection of the compound PHAR-DBH-Me (0.018-185 ㎍/kg) resulted in decreased blood pressure; maximum effect was observed at the dose of 1,850 ㎍/kg. A concentrationdependent increase in the coronary flow was observed in a Langendorff preparation. In the aortic rings, with and without endothelium, pre-contracted with PHEN (10^-6 M), the addition of PHAR-DBH-Me to the superfusion solution (10^-12-10^-5 M), produced a vasodilator response, which depends on the concentration and presence of the endothelium. L-NAME inhibited these effects. Addition of CB₁ receptor antagonist (AM 251) did not modify the response, while CB₂ receptor antagonist (AM630) decreased the potency of relaxation elicited by PHAR-DBH-Me. Indomethacin shifted the curve concentration-response to the left and produced an increase in the magnitude of the maximum endothelium dependent response to this compound. The maximum effect of PHAR-DBH-Me was observed with the concentration of 10^-5 M. These results show that PHAR-DBH-Me has a concentration-dependent and endothelium-dependent vasodilator effect through CB₂ receptor. This vasodilation is probably mediated by the synthesis/release of NO. On the other hand, it is suggested that PHAR-DBH-Me also induces the release of a vasoconstrictor prostanoid.
