How Cells Cheat Death

Cells are constantly fighting between life and death. It is believed that once cells go through certain incidences, their death is irreversible. Incidences such as, shrinkage, the breakdown of DNA or mitochondria, condensation of the nucleus, as well as activation of caspases. A new ability to replenished cells was recently discovered; it is called anastasis. […]

Photosynthesis Vs. Cellular Respiration the Major Processess in a Global Balance

There are two key processes that occur in nature to obtain energy, they are photosynthesis and cellular respiration. The derivative of the word photosynthesis is the process in which energy of sunlight is converted by plants to store chemical energy in carbohydrate bonds. Photosynthesis is known to be performed by plants, as is cellular respiration. […]

Analysis of the Role of the HIF-1

This paper by Shen and collegues describes the role of the HIF-1 gene and the gene’s response to low oxygen levels in Caenorhabditis elegans (C. elegans). The hypoxia-inducible transcription factor (HIF-1) plays a critical role in being regulating systematic activities. The HIF-1? subunit contains proline residues which, in the presence of high oxygen levels are […]

HeLa the Immortal Cell

Cells are the basic building blocks of life and make up all living organisms. There are two classifications of cells in every organism called prokaryotes and eukaryotes. A prokaryotic cell composes of single cell organisms like bacteria for example. While, a eukaryotic cell consists of multicellular organisms, the example for that is humans. The human […]

PKB and the Mitochondria: AKTing on Apoptosis

Function and Structure of PKB PKB contains three isoforms with catalytic domains similar to those in the AGC kinase family. PKB? was initially discovered through homology cloning and the similar appearance of its kinase domain resembled that of protein kinase A and C therefore it was named protein kinase B (PKB). It has two family […]

Apoptosis in each Living Thing

Apoptosis goes on in each living thing. It shapes the beginning life form of every animal and is behind the huge adjustments of caterpillars into butterflies and tadpoles into frogs. Some plant cells moreover deliberately execute themselves, for example, to stop an assaulting parasitic or bacterial tainting spreading. In run of the mill tissues there […]

A Form of Preprogrammed Cell Death

Apoptosis is a form of preprogrammed cell death. It can occur if DNA is too damaged or if a cell is infected and cannot complete its function anymore. There are two pathways to trigger cell death. The extrinsic pathway begins the process through external ligand binding. The intrinsic pathway begins by releasing mitochondrial proteins into […]

About the Cellular Basis of Cancer

At a cellular basis, cancer cells are not that different from normal cells. In fact, from a biological view point cancer cells originate from normal cells. The features of a cancer cell; such as migrating away from its origin point, mutating and replicating itself, evading cell death and providing itself with a supply of oxygen […]

Aminoglycoside-Induced Hair Cell Death and Potential Therapies

Introduction Hearing loss is the third most common disorder in the United States, being more prevalent than diabetes or cancer (Blackwell et al. 2014). Our ability to hear is dependent on hair cells that can translate the sounds we hear into electrical impulses that can be interpreted by the brain. When sounds waves enter the […]

Programmed Cell Death (Apoptosis)

Apoptosis is an event in which a cell is programmed and specifically sentenced to death. It happens naturally in the body. Apoptosis in greek means to fall off, and that’s one way to think about it. It’s as if one, or a few chosen cells are falling off a cliff, while the rest keep working. […]

Magnetism in Nanomaterials

The basic concepts regarding the interactions between magnetic nanoparticles and a static or time-varying external magnetic field were reviewed. How these pertain to current biomedical applications of magnetic nanoparticles were also analyzed. The focus was in particular on magnetic separation and drug delivery. Although these are only two of the many biomedical applications of magnetic […]

Idea of Photosynthesis by Jan Ingenhousz

To begin, the idea of photosynthesis was created by, according to Encyclopaedia Britannica, “”A Dutch scientist, Jan Ingenhousz. (Ingenhousz 1.) He was born in the Netherlands on December 8, 1730. Ingenhousz, is most known for his discovery of photosynthesis. According, to Encyclopedia Britannica, “”Ingenhousz discovered that light is necessary for photosynthesis, only the green parts […]

DNA and Mutations

Occurrence of mutation. Mutation is the process that produces a gene or a chromosome set different from the wild type. For instance this allows us to measure the frequency of mutation occurance.a cell caring mutation can be used as probes to disassemble the constituent parts of a biological function and to examine their workings and […]

Genetics

Introduction The hereditary molecule that is tasked with carrying genetic instructions that are used in all living things in development, growth, reproduction and functioning is referred to as deoxyribonucleic acid (DNA). DNA molecules consist of two strands which are bipolar and are mostly coiled near to one another to form a spiral. This strands are […]
