Abstract

Myopia and hyperopia have a significant clinical meaning as they can be the cause of low visual acuity or even blindness. Therefore, there is a high demand for all clinical investigations regarding the development of the eye and the creation of refractive errors. Nevertheless, not many papers have been published around the world which compared the prevalence of myopia as well as hyperopia among metropolitan and provincial schoolchildren. Whereas, in Poland there was not a single paper yet published concerning this topic. That is why the aim of this paper is to describe the prevalence of myopia and hyperopia among urban and rural schoolchildren in Poland. 2206 students were examined 1155 boys and 1051 girls, aged 10-14 years, mean age 11.9 (SD = 1.4). 614 boys in the age of 11.8 years (SD = 1.4) lived in the city, as 541 boys in the age of 11.9 years (SD = 1.4) lived in the countryside. 586 girls in the age of 11.8 years (SD = 1.5) lived in the city, as 465 girls in the age of 11.9 years (SD = 1.4) lived in the countryside. The examined students were Caucasian and lived in Szczecin, Poland or in villages located near Szczecin. The examination included retinoscopy under cycloplegia. The refractive error readings were expressed as...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.
