La escasez de agua en el presente y alrededor del planeta, es un problema grave. Es lo que se conoce como estrés hídrico y se produce cuando la demanda de agua potable es más alta que la cantidad disponi¬ble en nuestros mantos freáticos; es decir, cuando es¬tamos consumiendo más de lo que tenemos disponi¬ble en el subsuelo. Esa es justamente la triste situación que estamos viviendo hoy día, pues en varios países del mundo ¡ya no hay agua! Particularmente, en México, varios estados de la República están transitando por la escasez grave de agua. Por mencionarte algunos: Aguascalientes, Baja California, Nuevo León, Sonora, Sinaloa, Jalisco y Ciudad de México. Terrible, ¿verdad? Sólo hasta que carezcamos del vital líquido, nos tomaremos el tiempo para informa¬mos y darnos cuenta de la importancia que tiene ésta en nuestras vidas, ya que muchos humanos piensan en el agua...

Cotton crops were one of the most important during the 50 and 80 decades in Northern Sinaloa, Mexico from the economical point of view. However, external factors such as monoculture and sanitary issues caused its disappearance. Due to the need of diversifying the actual pattern of crops grown in the zone, a great possibility of re-growing cotton crop exists. Actually, there is lack of updated information about irrigation and agronomic management practices of the crop. In order to contribute to a new crop planning, an integral programming model was used to estimate planting dates and windows as well as irrigation planning at different operation levels. Field experiments were conducted at different locations of northern Sinaloa during the growing season 2011-2012 in Ahome and Guasave counties. Each plot had a dimension of 2 hectares and five varieties grown with the purpose of calibrating ...

Este trabajo presenta un avance de investigación interdisciplinaria que desarrolla perspectivas teóricas, analíticas e interpretativas, para el estudio situado de la alimentación, salud, nutrición y la cultura, en Latinoamérica, particularmente en el puerto y ciudad turística de Mazatlán, Sinaloa, México. Las miradas teóricas y las rutas metodológicas parten de considerar que, además de los evidentes aportes nutricionales, los alimentos son portadores de significados, entendidos éstos como atributos conferidos culturalmente. La revisión bibliográfica identificó una variedad de especies de patógenos potencialmente zoonóticos, transmitidos por peces en hospedadores acuáticos que son comunes en comunidades costeras del mundo, destacando la importancia del consumo de pescado crudo en la transmisión de parásitos y posible zoonosis con afección al humano. Asimismo, se exp...

The goal of this research is to carry out an inventory redistribution following the ABC classification of merchandise, as well as gauge improvement in indicators of inventory rotation and duration in a food production company in Sinaloa, Mexico. The methodology employed comprised 4 stages: a diagnosis of the current situation, generation of inventory redistribution proposals based on ABC classification, implementation and evaluation of results. Inventory rotation and duration performance indicators were measured prior and following implementation, achieving favorable results across 5 products with butter as the standout, whose weekly rotation was increased by 32,92 units while its warehouse time was cut by two days. The information was collected by observing and counting physical inventory units paired with verifying the inventory in the system. The study concluded that inventory managem...

Corn production is affected by fungi of the genus Rhizoctonia. The objective of this study was to characterize, using morphology, DNA sequence analysis, and pathogenicity, Rhizoctonia isolates associated with corn with banded leaf spot symptoms in commercial fields in northern Sinaloa. Diseased plants were collected in the municipalities of Ahome, El Fuerte, and Guasave, obtaining 27 isolates. Morphological characterization on PDA showed colonies with whitish to brown mycelium, pigment release into the medium, and amorphous, red and brown sclerotia with a diameter < 1 mm, characteristics described for Rhizoctonia. For molecular characterization, genomic DNA was extracted, part of the RPB2 gene was amplified by PCR, and the amplified products were sequenced. Phylogenetic analysis confirmed the identification of 18 isolates as Rhizoctonia zeae and 9 isolates as Rhizoctonia solani. The R...

El presente estudio tiene como objetivo identificar al agente causal de infecciones gastrointestinales de dos individuos con episodios de diarrea crónica y vómito durante actividades turísticas gastronómicas en el puerto de Mazatlán, Sinaloa en las costas del Pacifico Mexicano. Es el caso, del cebiche y mariscos crudos que están considerados como “patrimonios gastronómicos con gran valorización turística”; sin embargo, estos alimentos regionales podrían estar relacionados con la transmisión de infecciones parasitarias intestinales entre los turistas que los consumen. Este trabajo presenta dos casos de estudio con análisis clínicos de laboratorio (coproparasitológico y hemograma completo) de dos turistas; a) hombre de 57 años (turista internacional) y b) mujer de 26 años (turista nacional). Los estudios coproparasitológicos revelan la presencia de Blastocystis hominis...

The objective of this work was to identify the species of parasitic nematodes that infect the gonads of female “birdfish” Hyporhamphus naos Banford & Collette, 2001 (Hemiramphidae: Beloniformes). This species of fish is considered key in terms of the local artisanal fishery index, it is economically transcendental for fishermen and regional consumers who annually wait for its arrival in the bay to be consumed. The nematode Philometra Costa, 1845 (Nematoda: Philometridae) was identified parasitizing the female gonads of H. naos. Two immature female nematodes were found (prevalence 8%, mean abundance 0.08 and mean intensity 1). New information is recorded on the distribution of parasitic nematodes of this genus in this area of ​​the tropical Pacific and a new host. This is the first record of Philometra parasitic on female gonads in H. naos fish in Mexico. The first world recor...

The objective of this multidisciplinary interpretive research was to identify the motivations by which the national resident and tourists have a tendency to consume “rock oysters” Crassostrea iridescens (Hanley, 1854) during their daily lives or their stay in the port of Mazatlán, Mexico. The typical Mazatleca cuisine is of great interest, preferably for the consumer and generates a source of economic income for its residents. In Mazatlán, Sinaloa there is the custom of some coastal regional cuisines such as fish ceviche, the consumption of raw shellfish such as the oyster C. iridescens and aguachile (raw shrimp seasoned with lemon, salt, pepper, and serrano chili).
