Four Lenses of Gender Differences

Words: 661 Pages: 2 4967

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 7679

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).

The Immune System – Immunity

Words: 1563 Pages: 5 4523

The immune system is a structure of bodily safeguards that protect the human body from antigens such as infectious and venomous agents. This system recognizes, processes, and then eliminates antigens. Based on descriptions and memory, the immune system deterrence is categorized into two types: innate and adaptive immunity. The coordination and development of a well-adjusted mechanism to obliterate pathogens are shared by both systems. Specific elements acclimate themselves to each new class of illness encountered and are hence able to […]

Diseases are Associated with Cell Death

Words: 377 Pages: 1 4322

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 […]

Endothelial Dysfunction Induced by Exposure to High Glucose Conditions

Words: 789 Pages: 3 3993

Abstract Introduction Ropivacaine is one of the most widely used amide-based local anesthetics in both clinical and dental settings. Local anesthetics work by blocking neural signal transduction through the inhibition of sodium ion uptake in a limited area of the body and for a limited amount of time [16]. While research has suggested potential cytotoxic and apoptotic effects of amino amide local anesthetics including bupivacaine, ropivacaine, levobupivacaine, and mepivacaine, a recent literature review reported that among them, ropivacaine had the […]

Magnetism in Nanomaterials

Words: 282 Pages: 1 4298

The basic concepts regarding the interactions between magnetic nanoparticles and a static or time-varying external magnetic field were reviewed. We also analyzed how these pertain to the current biomedical applications of magnetic nanoparticles, focusing particularly on magnetic separation and drug delivery.

PKB and the Mitochondria: AKTing on Apoptosis

Words: 574 Pages: 2 4125

Function and Structure of PKB PKB contains three isoforms with catalytic domains similar to those in the AGC kinase family. PKB, initially discovered through homology cloning, maintained a similar appearance to protein kinase A and C in its kinase domain, and therefore, was named as Protein Kinase B (PKB). It has two family members: PKB/c-Akt2 (c-Akt is a cellular homologue of PKB) which is expressed mainly in insulin-target tissues, and PKB/c-Akt3 which is highly expressed in the brain and testis […]

Why Protect Biodiversity and Save Endangered Species?

Words: 4305 Pages: 14 4639

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 […]
