Abstract

Urban environmental pollutants, resulting from the inadequate control in the industries and from the use of vehicles, still represent a great danger for millions of people all around the world. We made a study in healthy young people without family history of atopy that lived in Guadalajara's downtown, as well as in another group of young people who lived in a rural area. According to the census of the year 2000, Guadalajara city has a population of 4 million habitants, and a vehicle number of about a million. The immunological parameters that we studied were: IgG, IgA and IgM immunoglobulins by nephelometry, serum levels of proinflammatory cytokines IL-6, IL-1alpha, IL1-beta and TNF-alpha by ELISAs test, and the phagocytic index in polymorphonuclears. The atmospheric parameters were: NO2, O3, SO2, CO and the suspended particles that were less than 10 micrometers (PM10). These parameters were obtained from a mobile unit found at the Instituto de Astronomia y Meteorología de la Universidad de Guadalajara, and from an automatic station of environmental monitoring. It stands out the high concentrations of NO2 and PM10, which in several occasions were over the standards established by the WHO. IgG, IgA and IgM immunoglobulins were ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
