Histological Quantification to Determine Lung Fungal Burden in Experimental Aspergillosis

Here we describe a protocol to determine pulmonary fungal burden in mice with invasive aspergillosis by quantification of Gomori's modified methanamine silver staining in histological sections. Use of this method resulted in comparable results with less animals compared to assessment of fungal burden by quantitative PCR of lung fungal...

Erikson's Theory on Socioemotional Development during Childhood

Erik Erikson, a stage theorist, adapted Freud's theory to emphasize social factors in personality development throughout life, a concept known as psychosocial development. Unlike Freud, who focused on early childhood, Erikson believed that personality evolves across eight life stages, each marked by a specific challenge or "crisis." Successful resolution of each stage fosters competence, while failure may lead to feelings of inadequacy.
The first four of Erikson's eight...

Measurement of the In Vivo Burden of Bacteria Expressing Luciferase in an Insect Larva

This video showcases the in vivo bacterial burden measurement using Bacillus Calmette-Guérin, BCG, lux-infected insect larvae. The process involves larval homogenization, treatment with a luciferase substrate, and bioluminescence measurement to determine relative light units that correlate with bacterial...

Quantitation of Intra-peritoneal Ovarian Cancer Metastasis10:58

Quantitation of Intra-peritoneal Ovarian Cancer Metastasis

Ovarian cancer metastasis is characterized by numerous diffuse intra-peritoneal lesions, such that accurate visual quantitation of tumor burden is challenging. Herein we describe a method for in situ and ex vivo quantitation of metastatic tumor burden using red fluorescent protein (RFP)-labeled tumor cells and optical...
