The nervous system has two main parts - the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain and spinal cord. The brain controls functions like thought, memory, movement, and senses. It is made up of regions like the cerebrum, cerebellum, and brain stem. The spinal cord acts as a pathway for information between the brain and body and helps coordinate reflexes. The peripheral nervous system connects the central nervous system to the rest of the body.
The human nervous system consists of two main parts: the central nervous system and the peripheral nervous system. The central nervous system is comprised of the brain and spinal cord.

Recombinant DNA technology involves recombining DNA segments and allowing recombinant DNA molecules to enter cells and replicate. It was developed in 1973 by scientists Boyer and Cohen. The basic principle is to insert DNA into a vector, introduce it into a host cell where it replicates and produces the gene. Applications include producing human proteins like insulin through genetically engineered bacteria. Safety issues involve ensuring recombinant bacteria do not escape the laboratory and cause epidemics, which is addressed through physical and biological containment methods overseen by regulatory committees.
Nanotechnology has many applications in medicine including drug delivery, cancer therapy, Alzheimer's disease treatment, and tuberculosis treatment. Nanoparticles are effective for drug delivery because their small size allows them to be taken up by cells and later break down, releasing the pharmaceutical agent inside the cell. Gold nanoparticles have been used to treat cancer by absorbing radiation and heating up to kill tumor cells. Nanoparticles have also been engineered for targeted delivery of drugs to the brain and lungs for Alzheimer's and tuberculosis treatment respectively. While promising, nanomaterials must also be evaluated for toxicity to address potential health and environmental risks.

There are two main types of immunity: active immunity, which is developed from exposure to an antigen either through natural infection or vaccination; and passive immunity, which can be acquired naturally from antibodies in breast milk or artificially through antibody administration. Both active and passive immunity can be naturally developed or artificially stimulated.
The document provides an overview of the human reproductive system, including definitions and key parts. It describes both male and female external and internal reproductive organs. The male system produces sperm and the female system supports pregnancy and childbirth. The reproductive cycle in females includes menstruation, ovulation, and changes regulated by hormones. Fertilization can lead to pregnancy, in which a placenta develops to support fetal growth until birth, after which lactation provides nutrition for an infant.
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
