First Record of Ulva pertusa Kjellman (Ulvales, Chlorophyta) in the Pacific Coast of Mexico

Aguilar-Rosasl, Racal,Aguilar-Rosas, Luis E.,Shimada, Satoshi The Korean Society of Phycology 2008 ALGAE Vol.23 No.3

Based on samplings during 2006-2007 on the intertidal zone of Playa Tampico, Eréndira and Punta Baja, Baja California, Ulva pertusa Kjellman (Ulvales, Chlorophyta) was recorded for the first time for the Pacific coast of Mexico. An alga native to Asia, U. pertusa has just recently been recorded in the southern coast of California (USA). The identification of U. pertusa was based on the observation of the morphology and reproductive characters of the collected specimens. Furthermore, the species identity was confirmed by molecular comparison between nuclearencoded ITS2 sequences of the Mexican samples and those of other Ulva species in GenBnak data. Habitat and distribution of U. pertusa along the Pacific coast of North America are also described. Considering our new report of its occurrence in Mexico, we conclude that U. pertusa is expanding its geographical distribution by trans-ocean introductions.

New Record of Sargassum filicinum Harvey (Fucales, Phaeophyceae) in the Pacific Coast of Mexico

Aguilar-Rosas, Luis E.,Aguilar-Rosas, Raul,Kawai, Hiroshi,Uwai, Shinya,Valenzuela-Espinoza, Enrique The Korean Society of Phycology 2007 ALGAE Vol.22 No.1

Sargassum filicinum Harvey, a brown alga (Phaeophyceae) native to Northeastern Asia, has been recently reported from the coast of Southern California (USA). Here we report the occurrence and range extension of this introduced species, as we found the alga at La Jolla and Rancho Packard in Todos Santos Bay, Baja California, Mexico. The first collections of S. filicinum correspond to several immature plants, found on September 8, 2005, drifting in the intertidal zone at La Jolla. Later on November 9, 2006, we found a well-established population in Rancho Packard in the middle intertidal zone to 2 m depth. Since S. filicinum is an annual monoecious species with air bladders, the risk there is a high risk of spreading rapidly along the Pacific, as in the case for S. muticum. The population in Rancho Packard extends 500 m along the coast, consisting mainly of young plants with an average length of 30 cm and a density of 5 thallus/m2. This is the first record of this invasive species for the Mexican Pacific coast, and it represents the southern limit along the Pacific coast of North America. This finding suggests that this invasive species has successfully colonized the Pacific coast of North America and its distributional range is still expanding.

New Records of Marine Rhodophyta from the Pacific Coast of Mexico

Aguilar-Rosas, Raul,Aguilar-Rosas , Luis E.,Mateo-Cid, Luz Elena,Mendoza-Gonzalez, Catalina The Korean Society of Phycology 2007 ALGAE Vol.22 No.3

Two species of marine red algae, Jania ungulata (Yendo) Yendo f. brevior (Yendo) Yendo and Peyssonnelia japonica (Segawa) Yoneshigue (Rhodophyta) were collected for the first time from Mexican Pacific coast. Their vegetative and reproductive structures are described, as well as the habitat where they were found and their geographical distribution along the Pacific coasts of Mexico. Jania ungulata f. brevior is a commonly growing epiphytic and Peyssonnelia japonica is epiphyte. The fact that we found this new records in Mexican coast is noteworthy, due that this species are originally described in Japanese coast. The absence of records of this species in the Mexican coast is likely related in part to the lack of specific collections and the fact that the specimens are small and delicate, and may commonly be unnoticed during samplings.

Organoids as host models for infection biology – a review of methods

Aguilar Carmen,Alves da Silva Marta,Saraiva Margarida,Neyazi Mastura,Olsson I. Anna S.,Bartfeld Sina 생화학분자생물학회 2021 Experimental and molecular medicine Vol.53 No.-

Infectious diseases are a major threat worldwide. With the alarming rise of antimicrobial resistance and emergence of new potential pathogens, a better understanding of the infection process is urgently needed. Over the last century, the development of in vitro and in vivo models has led to remarkable contributions to the current knowledge in the field of infection biology. However, applying recent advances in organoid culture technology to research infectious diseases is now taking the field to a higher level of complexity. Here, we describe the current methods available for the study of infectious diseases using organoid cultures.

Varying the ratios of NIPAAm to HMAAm monomer resulted in different LCST properties for the synthesized copolymer and further utilized for an on-demand drug release. Biocompatibility test using NIH-3T3 fibroblast cells indicates that the composite with drug content is biocompatible and the in-vitro cancer cytotoxicity test using ESO26 and OE21 cancer cells proved that the material shows cancer cytotoxic properties via combination of dual drug and hyperthermia therapy.

Synthesis of NiMn2O4 assisted by high-energy ball milling of NiO-MnO powders

Aguilar-Garib J. A.,Sánchez-de-Jesús F.,Bolarín-Miró A. M.,Ham-Hernández S. 한양대학교 세라믹연구소 2011 Journal of Ceramic Processing Research Vol.12 No.6

This work presents a useful example of the fact that mechanical activation promotes solid state reaction in the preparation of a NiMn2O4 from NiO and MnO; shown evidence demonstrates that high-energy ball milling of MnO and NiO powders followed by a heat treatment can be considered a possible route for the synthesis of this compound. The powders were milled at room temperature in a shaker mixer in a weight ratio 1 : 10 of powder to zirconia balls. X-ray diffraction patterns show small differences among the powders milled for different times, while post milling heat treatments conducted at different temperatures for 1 hour showed an increase in the formation of the nickel spinel with a tetragonal structure, which was successfully obtained with this combined mechanosynthesis (MSP) - heat treatment method.
