Abstract

A significant proportion of Schistosoma mansoni schistosomula die soon after penetration of mammalian host skin. This study was conducted to further define the host cellular response which occurs in the skin and which may contribute to early schistosomulum death in the resistant CDF rat and the more susceptible BALB/c mouse. In primary abdominal skin exposures of both hosts the initial 6-hour response is marked edema and epidermal cell disruption in the schistosomulum penetration tracts accompanied by migration of neutrophils to surround the parasites and into damaged areas of the epidermis and dermis. Challenge exposures in previously infected hosts result in more intense exudative inflammation than is observed in initial exposures with the additional infiltration of eosinophils into the dermis and epidermis. Mast cells are numerous and are occasionally observed degranulating. By 24 hours following either initial or challenge exposures the infiltration of granulocytes is more intense. Focal areas of neutrophils, eosinophils, and necrotic cells are frequent in the epidermis. Postcapillary venules contain large numbers of granulocytes. The vascular endothelium is frequently vacuolated and occasionally exhibits focal degeneration...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.

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.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

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.

Torsion Dystonia

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
