DNA Damage Repaired through Antioxidant Enzymes: Genetic Restoration

Pooja Kashyap

At the fundamental level, function of human cell is to convert nutrients into energy and useful products that sustain life. In the process, these cells give out certain waste products that otherwise cause harm to the inner environment. For instance, reactive oxygen species (ROS) molecule is one of the natural byproducts of cellular metabolism. ROS are highly reactive molecules that contain oxygen atoms with unpaired electrons.

Protein-based Nano Device to Influence Cell Behaviour: Synthetic Biology

Pooja Kashyap

Conventional methods in synthetic biology for cell-based therapies focus on using specific proteins to achieve a desired effect in cells. For instance, cancer treatment involves certain proteins to kill cancer cells. while, some proteins are used to help tissues regenerate after an injury. This process, however, is lengthy as it takes time for the proteins to be produced and break down. Additionally, it requires a lot of energy from the cells.

Biomolecular Condensates possesses an Electric Potential: Biological Chemistry

Pooja Kashyap

Electrical charges have a vital role in majority of biological processes in the human body. In fact, the human body is an incredibly complex electrical system that relies on the flow of electrical charges to carry out its functions. Electrical signals, for instance, are not only used by the brain and nerves to communicate with each other. But the same signals also allow us to move our muscles, feel sensations, and think. At the cellular level, ions such as sodium, potassium, and calcium work in tandem to regulate various processes…

Distinct Activation Patterns of Projection Neurons: Cortical Dynamics

Pooja Kashyap

Cerebral cortex is the outer layer of cerebrum, that is the largest part of the brain. All kinds of higher-level processes such as language, memory, and decision-making are performed in this region. The complex, densely packed structure is saturated with various types of neurons. It is extremely difficult to image its neuronal dynamics with the necessary spatial and temporal resolution. So far, fMRI (functional magnetic resonance imaging) technique is widely used for studying brain activity. However, when it comes down to examine neural circuitry at the point of a single…

Astrocytes are the Information Regulators: Brain Pathology

Pooja Kashyap

Astrocytes are the non-neuronal cells that provide support and maintenance to neurons in the brain and spinal cord. They have a star-shaped morphology, with multiple branching processes that extend out from the cell body. They form specialized junctions with blood vessels for regulating the transport of nutrients and other molecules between the brain and the bloodstream.

Neuro-Stack to records Single Neuron Activity: Brain Mechanisms of Movement

Pooja Kashyap

New technologies have revolutionized many fields, including medicine and neuroscience. Advances in engineering, materials science, and computer technology have enabled the development of increasingly sophisticated devices for recording and analysing biological signals, such as brain activity, with unprecedented precision and accuracy. For instance, electroencephalography (EEG) is a non-invasive technique that measures electrical activity in the brain using electrodes placed on the scalp. With the advancement in electronics and computing the EEG signals can now be recorded with greater precision and resolution.

Hydrogels Promote Neuronal Tissue Growth: Brain Healing

Pooja Kashyap

Degeneration of brain cells could be a natural aging process. However, destruction or deterioration of brain cells could occur due to a wide range of internal as well as external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage. Science has tremendously advanced when it comes to health care and disease control. There are new and radical developments in the field of neurology alone. One such progress is brain tissue reconstruction.

Exon Junction Complex controls mRNA: RNA Methylation

Pooja Kashyap

Our gene expression is regulated by RNA methylation. Same process also affects various cellular processes like differentiation and development. Lately, University of Chicago researchers, led by Chuan He, have uncovered new insights into how genes work by solving a long-standing mystery related to RNA methylation. Researchers in Chuan He’s lab have been studying RNA methylation and its potential impact on human health for over a decade.

Gas Entrapping Materials to Mitigate Tumor Hypoxia: GeM Technology

Pooja Kashyap

Cancer treatments such as radiotherapy and chemotherapy have been shown to be less effective when exposed to a hypoxic environment. In fact, low oxygen levels in tumors can also escalate disease progression. Hyperbaric oxygen therapy and microbubble infusion are the two techniques through which oxygen levels in tumors can be increased to improve treatment outcomes.

Vitamin D Deficiency Associated with Melanoma: Skin and Bone Health

Pooja Kashyap

Vitamin D plays an important role in regulating normal function of human body. It helps the body to absorb and retain calcium and phosphorus, which are critical for building bone. In addition, it also helps in boosting energy levels. Epidemiological studies too, have shown that Vit-D deficiency is closely associated with common chronic diseases such as bone metabolic disorders, tumors, cardiovascular diseases, and diabetes. In addition, similar corelation between vitamin D and skin cancers have also been investigated.

Compact Cas7-11 Enzyme for RNA Editing: CRISPR-Cas System

Pooja Kashyap

The CRISPR CAS9 system famously known as genetic scissors was discovered by Emmanuelle Charpentier and Jennifer Doudna in 2012. And since then, the new tool has been studied extensively across global academia. Initial studies of the genome editing tool altered only the DNA. However, lately the CAS system is also studied for editing RNA. What is CRISPR-CAS system? CRISPR-CAS system is an adaptive immune system of bacteria, which protects it from invaders. Also, it defends the bacterial host from renewed infection as it memorizes previous infections. DNA has the fingerprint.…

Multiple Modes of Dendritic Integration in Single Neurons: Brain Computation

Pooja Kashyap

Dendrites, branch like extensions protruding from a single neuron, participate in computations and permutations to give a synchronized output to the neuron. Researchers at MIT have now demonstrated that not only different types of dendrites (of a single neuron) collect input from various regions of the brain, they also process that information in different customized ways.
