The document discusses botanical gardens, including their purpose of conserving and researching plant collections for education. It notes that the earliest botanical gardens were created in the 16th century as medicinal gardens in Italian universities. The document then provides details on several famous botanical gardens in India, including their locations, areas, founding, and prominent plant species. It discusses the roles of botanical gardens in plant conservation through cultivation, research, education, and sustaining plant resources. Botanical gardens are described as important for preserving endangered plant ecosystems and the animals that depend on them.
Endangered Species.pdf
The document discusses endangered species and the threats they face. It provides examples of endangered animal species such as black rhinos, Sunda tigers, blue whales, and Sri Lankan elephants. Habitat loss is one of the main reasons species become endangered, as human activities like development, agriculture, and deforestation reduce available habitat. Disease and environmental factors like climate change also endanger plant and animal populations. The document encourages actions like reducing one's carbon footprint, supporting environmental organizations, and becoming more informed about endangered species and conservation issues.
instrumental value of species
This document discusses the various types of value that species can provide, including instrumental value which relates to the benefits species provide to humans, and intrinsic value which relates to a species' inherent right to exist. It then examines these values in more depth, describing the food, medicinal, economic, ecological, and other values provided by microorganisms, plants, insects, birds, mammals and other animal species. Examples are given for many different types of species. The document also discusses species' recreational, spiritual and indicator values and how they are important for research, education and ecosystem functioning.
Biodiversity
This document discusses biodiversity, including its definition, levels, hotspots, and importance. It also covers threats to biodiversity like habitat loss and methods of conservation, both in-situ (within natural habitats like protected areas) and ex-situ (outside habitats, including seed banks, zoos, and botanical gardens). India is highlighted as one of the most biodiverse countries with two biodiversity hotspots, the Western Ghats and Eastern Himalayas, that face serious threats and support many unique and endangered species.
The-World-of-Plants.pdf
Welcome to the fascinating world of plants. They are essential to life on earth and come in many shapes, sizes, and colors. Let's take a closer look.
Fernbank Museum Lecture: Deadly cures - 2015
In March 2015, Dr. Quave presented: "Deadly Cures: Medical Discoveries from Poisonous Plants" as a ticketed public lecture at Fernbank Museum in Atlanta, GA as part of their special exhibit "The Power of Poison". In this talk, she discussed the reasons why plants produce poisonous compounds and the myriad ways that humans have used these chemicals for both health and harm.
Abstract:
Plants produce a fascinating mixture of biologically active compounds for the purposes of defense against threats in their environment. Over time, mankind has discovered ingenious ways to transform and make use of plant poisons ranging from applications in agriculture, fishing, hunting, and traditional medicine. Oftentimes, the distinction between poison and medicine comes down to two simple points: dose and intent. In this lecture, Dr. Quave will discuss how the scientific study of poisonous plants has led to the discovery of some of the leading pharmaceutical drugs in use today.

Importance of plants
Plants are vital for all living organisms. They produce oxygen through photosynthesis, provide food and shelter for animals, and food, medicine, fuel, and raw materials for humans. Plants also play a key role in the environment by absorbing carbon dioxide, cleaning the air, preventing water and soil pollution, reducing temperatures, and reducing global warming. They are essential for ecosystems and enhancing natural beauty. Due to their many benefits, plants are important for microorganisms, animals, humans, and the environment.
Gene bank and plant conservation
This document discusses different types of gene banks used for conserving genetic material. It describes seed banks, tissue banks, cryo banks, pollen banks, field gene banks, sperm banks, and ova banks. Seed banks preserve dried seeds at low temperatures, while tissue banks preserve seeds or embryos in liquid nitrogen. Field gene banks involve planting species to compare diversity. Sperm and ova banks collect and store human reproductive cells from donors for use in fertility treatments or third party reproduction. The document also mentions the importance of gene banks for conserving crop diversity, and some drawbacks like power failures that can impact genetic material preservation.

Cell Therapy Expansion and Challenges in Autoimmune Disease
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.
