Climate and Socio-Sexual Environment Predict Interpopulation Variation in Chemical Signaling Glands in a Widespread Lizard.

Many animal species show considerable intraspecific phenotypic variation. For species with broad distributions, this variation may result from heterogeneity in the strength and agents of selection across environments and could contribute to reproductive isolation among populations. Here, we examined interpopulation variation in a morphological trait related to chemical communication, femoral pore number (FP), using 3437 individuals from 55 Pyrenean populations of the common wall lizard (Podarcis muralis).

Malaria, Dengue Fever, and Leptospirosis in the Urabá Antioqueño Region, Colombia: Etiological and Molecular Characterization among Patients with Acute Undifferentiated Febrile Illness.

Acute undifferentiated febrile illness (AUFI) is the main cause of medical attention in the tropics worldwide. Malaria, arboviral diseases, and leptospirosis are the most important etiologies. These are highly endemic in the Urabá antioqueño, Colombia, being the main causes of fever in several municipalities in this region.

[Incidence of beer spoilage microorganisms in Buenos Aires microbreweries].

Microbial contaminations pose a significant concern within the brewing industry, exerting negative effects on the organoleptic quality of the product and leading to substantial economic losses. The exponential proliferation of craft breweries in Argentina in recent years has heightened the demand for constant improvements in processes to ensure excellence in beer production. However, the stringency of microbiological quality controls remains a vulnerable area.

Characteristics of Madariaga and Venezuelan Equine Encephalitis Virus Infections, Panama.

Madariaga virus (MADV) and Venezuelan equine encephalitis virus (VEEV) are emerging arboviruses affecting rural and remote areas of Latin America. However, clinical and epidemiologic reports are limited, and outbreaks are occurring at an increasing frequency. We addressed the data gap by analyzing all available clinical and epidemiologic data of MADV and VEEV infections recorded since 1961 in Panama.

Reliable replicative lifespan determination of yeast with a single-channel microfluidic chip.

Saccharomyces cerevisiae is a powerful model for aging research due to its short lifespan and genetic malleability. Microfluidic devices offer an attractive approach enabling rapid monitoring of hundreds of cells during their entire replicative lifespan (RLS). Yet, key operational issues such as contaminations, cell loss, and cell-aggregates-dependent flow obstruction can hinder RLS experiments.
