Four Lenses of Gender Differences

Words: 661 Pages: 2 5827

People often view sex and gender as the same; however, that is not the case. Sex refers to the chromosomal and anatomical appearance of which a person was born with, whereas gender is the social role that one strongly identifies with, which may not always be the same as one’s assigned sex. Debates arise when people associate sex with gender, and while there may be correlations between the two, they are certainly not the same. Sociologists view gender through four […]

The Effects of Building Construction on Wildlife Habitats

Words: 2074 Pages: 7 9114

Conserving habitats is not an easy task. The number of threatened and endangered species in the United States and critical habitats is constantly being destroyed (Shilling 1662). With one-quarter of mammal species at risk of extinction and amphibians on the decline, more needs to be done to protect wildlife habitats. Plans to protect species tend to be for well-known animals such as the bald eagle or the gray wolf. As a result, many species are barely surviving. Conservation biologists warn […]

Diseases are Associated with Cell Death

Words: 377 Pages: 1 4886

Regulation of cell death is vital for development, pathogenesis, and homeostasis. Both acute and chronic diseases are associated with excessive cell death, which results in tissue damage. Caspase-dependent apoptosis is a type of programmed cell death implicated in both normal and disease pathogenesis. Ferroptosis is distinct from other cell death modalities based on morphological, biochemical, and genetic criteria. Ferroptosis is a pathogenic programmed cell death characterized by the iron-mediated production of toxic lipid hydroperoxides. This unique form of cell death […]

Why Protect Biodiversity and Save Endangered Species?

Words: 4305 Pages: 14 5218

Abstract Biodiversity on the planet is rapidly declining with the sharp increase in species extinction rates. As population numbers for many wildlife species continue to fall, research has shifted to applying molecular biology techniques in order to preserve the genetic presence of species on the planet even if the species itself is no longer able to survive. Ben-Nun and colleagues showed somatic cells of endangered species could undergo a reprogramming process to a state of pluripotency that is similar to […]

Stem Cells: Medical Frontiers

Words: 1068 Pages: 4 4853

Introduction A stem cell starts as an undifferentiated cell capable of self-renewal, producing daughter cells that remain as stem cells, or maturing into a specific cell type through differentiation (Can/Hematol 2008). The potency of a stem cell, or its ability to self-renew and differentiate, varies across types. For instance, one type of stem cell may differentiate into all adult cell types, while another can only mature into a single somatic cell type. The presence of stem cells is vital for […]
