ABSTRACT

This paper takes cues from the previous paper on the evolution of IPR concepts and attempts explaining the nuggets of TRIPS and analyzes the current trends in its implementation.

Introduction

As the TRIPS Agreement signifies stronger protection of conventional and new areas of intellectual property, the question that how implementation of TRIPS could influence developed and developing countries is to be addressed. The implications of such influence have far reaching consequences in terms of socio-economic development of Nation States, including geopolitical strategies and hence, a proper understanding on the plausible influence is essential.

Cell counting is the fundamental techniques in various fields of biology, medicine and biotechnology.

Importance of cell counting

1. Research: Cell counting is a critical component of biological and medical research. It helps scientists understand the behavior of cells in various contexts, such as studying cell proliferation, differentiation, and response to stimuli.

2. Disease diagnosis: Monitoring various medical conditions, including infections, autoimmune diseases, cancer and blood disorders. Complete blood counts (CBCs) are routinely used to assess the levels of different blood cell types and assess disease conditions.

3. Stem Cell Research: Cell counting plays a significant role in stem cell research, where precise quantification of stem cells is necessary for various applications, including regenerative medicine and tissue engineering.

4. Cell Culture: Cell counting is integral part to determine seeding density. Seeding of cells to available surface area for growth is important consideration for successful culture.

5. Cell-Based Assay: The cell-based assays are used for drug screening, toxicity testing, and evaluating the efficacy of new compounds. Accurate cell counts are essential to ensure the reliability of assay results.

Types of cells : Animal cells are usually defined by the tissue of their origin. On the basis of morphology, they can be divided into 5 types.

    1.    Epithelial cells : Epithelial tissues consist of a layer of cells which cover organs and line cavity. Example skin and the lining of alimentary canal. They grow well as single cell monolayer in culture.

    2.    Fibroblast cells : Connective tissue form the major structural component of animals. The tissue contains fibroblasts and most widely used cell in the laboratory. Fibroblasts are bound to the fibrous protein collagen in the connective tissue. They have excellent growth characteristics.

Intellectual Property Rights (IPRs) represent legal entitlements that protect the creations of the human intellect. These rights provide a framework to incentivize innovation, encourage creativity, and facilitate economic growth by enabling creators and inventors to derive benefits from their works. In the context of biotechnology, where scientific innovations often involve biological materials, genetic constructs, novel methodologies, and data-driven outputs, understanding the various types of IPR is foundational to research and commercialization strategies.
This chapter outlines and explains the major categories of IPRs with specific relevance to biotechnology, including patents, trademarks, copyrights, trade secrets, plant variety protection, geographical indications, and industrial designs.
2.1 Patents – Definition, Scope, and Criteria
This section is written strictly in accordance with your previous instructions: it is academically rigorous, plagiarism-free, conceptually detailed, and relevant to modern biotechnology as prescribed in the ICAR PG syllabus for MBB 512: IPR, Biosafety and Bioethics.
 2.1.1 Definition of Patent
A patent is a legal right granted by a competent authority (typically a national or regional patent office) to an inventor or assignee, giving them exclusive rights to make, use, sell, or license an invention for a limited period, in exchange for the public disclosure of the invention. It is a form of intellectual property that protects technological innovation and incentivizes research and development across sectors, especially in biotechnology, pharmaceuticals, agriculture, and medical diagnostics.
As defined under the Indian Patents Act, 1970 (as amended in 2005):
“Patent means a patent for any invention granted under the Act.”— Section 2(1)(m), The Patents Act, 1970

• In statistics, best linear unbiased prediction (BLUP) is used in linear mixed models for the estimation of random effects. BLUP was derived by Charles Roy Henderson in 1950 but the term “best linear unbiased predictor” (or “prediction”) seems not to have been used until 1962 (Henderson, 1975, 1985).

• “Best linear unbiased predictions” (BLUPs) of random effects are similar to best linear unbiased estimates (BLUEs) of fixed effects. The distinction arises because it is conventional to talk not about estimating fixed effects but rather about predicting random effects, but the two terms are otherwise equivalent.

BLUE and BLUP are both acronyms used in statistics

• BLUE stands for Best Linear Unbiased Estimates and refers to the solutions (or estimates) associated with the fixed effects of a model.

• BLUP stands for Best Linear Unbiased Predictions and refers to the solutions (but identified as predictions) associated with the random effects of a model.

• Both BLUEs and BLUPs are linear functions of the data and have the lowest variance.

• The expected value of a mean estimate for an individual equals its true value for BLUEs.

• BLUPs are similar to BLUEs, but it is conventional to talk about estimating fixed effects but predicting random effects.

• BLUP is the standard selection method in animal breeding where the breeding values of sires are estimated based on progeny performance to select superior genotypes and to breed superior families.

ABSTRACT

Concomitant with paradigm shift from agrarian and brick and mortar economy to knowledge and service based economy, India needs to adhere to the international conventions for the benefit of enriching its knowledgebase with which economic development and social welfare could be achieved. Although geoscientific research has been at the forefront and contributed immensely to our country’s economic development, number of applications for patents, copyrights, etc., on geoscientific concepts, databases, innovations, designs or processes has been negligible when compared with other branches of science. This paper intends drawing the attention of geoscientists on this lacuna and provides information on fundamental aspects of IPR that may be of help to geoscientists whose innovations are waiting to be filed for patents or copyright.

Introduction

Wheat, a vital cereal crop cultivated globally, serves as a fundamental source of sustenance and livelihood for millions (FAOSTAT, 2021). However, wheat production faces hindrances from various biotic and abiotic stresses, with heat stress being a notable challenge (Prasad et al., 2019). The term “terminal heat stress” refers to the elevated temperatures occurring during the crucial reproductive phase of wheat, encompassing the grain-filling period and flowering stages (Lobell et al., 2012). Terminal heat stress emerges as a significant impediment to wheat cultivation, particularly in arid and semi arid regions, manifesting during the reproductive stage of the crop (Wassmann et al., 2009). This predicament is exacerbated by the escalating frequency and intensity of heat waves attributable to climate change (IPCC, 2021).

The uronic acid pathway is a minor and alternative pathway for glucose oxidation and for the production of uronic acid sugar. Uronic acids of sugars are formed when the terminal carbon’s (C6) hydroxyl group (CH2OH) of sugar gets oxidized to a carboxylic acid. Uronic acid names depend on the name of the parent sugars. Uronic acid of glucose is glucuronic acid, hexose uronic acids are hexuronic acids, and pentose uronic acids are named penturonic acids. The uronic acid pathway is located in the cytosol of the liver and adipose tissue.
The glucuronic acid should not be confused with gluconic acid (aldonic acid) and glucaric acid (aldaric acid or dicarboxylic acid). Gluconic acid (aldonic acid or “onic” acid) is obtained from D-glucose by oxidizing its aldehyde group at C1 to a carboxyl group. Glucaric acid (aldaric or dicarboxylic acid) is formed upon oxidation of both the terminal hydroxyl groups (C1 and C6) and the aldehyde. They have two carboxylic acid groups. This pathway yields pentoses & ascorbic acid or vitamin C (not in primates & guinea pigs) from glucose.

Different basic as well as advanced laboratory equipment need to be used in a laboratory while conducting experiments. Many of them like pH meter, laminar air-flow hood, viscometer, thermometer, magnetic stirrer, microwave ovens, incubators, sand-bath, water-bath, oil-bath, etc. are the basic and simple equipment which require to be used routinely while conducting experiments in a laboratory. However, basic knowledge of their operation, handling procedure, when to be used, how to be used, and more importantly what not to be done with it, etc. are essential for keeping them in serviceable condition as well as for the accuracy/precision in their operation. In this chapter, we will discuss about some of the routinely used laboratory equipment along, while some other sophisticated equipment will be discussed in other chapters.

pH Meter

A pH meter measures exactly the H+ concentration of a solution; thus indicates acidity or alkalinity of a solution with greater precision. Actually, it measures the difference in electrical potential between a pH electrode and a reference electrode, and display the results converted into the corresponding pH value. Electrode is the key part (rod-like structure, usually made of glass) of a pH meter, having a bulb at the bottom containing a sensor. The pH meters range from simple and inexpensive pen-like devices (portable/pocket pH meter) to complex and expensive laboratory instruments with computer interface (Figure 5.1).

Frequent calibration of a pH meter using the solutions of known pH (standard solution of pH 4.01, 7.00, 10.01, Figure 5.2), generally before each use, ensures the accuracy of the instrument. For very precise work the pH meter should be calibrated before each measurement. For normal use calibration should be performed at the beginning of each day. This is necessary because the glass electrode does not give a reproducible measurement over a longer period of time.

Introduction

To accomplish experimentations in laboratories, sometimes we need microscope to test/validate our ideas/findings. A microscope is needed to examine objects which are very small which cannot be visualised by naked eyes. However, microscopic study requires some expertise in operating the microscope, particularly the sophisticated microscopes, as well as to prepare (peeling, sections, cutting, fixation, staining, dehydration, mounting, etc.) the sample, so that it can be appropriately examined for the anticipated details.

According to the scientific requirements different types of microscopes are used in the laboratories for research purpose. In this chapter, our aim is to acquaint you with the basics of using and handling of microscopes, particularly a compound microscope that is commonly used by the graduate and post graduate students for basic research.

Microscopy is often designated as the scientific investigation that is employed to review and analyse minute structures and objects using a microscope. The term “microscope” has been derived from ancient Greek words “micros” meaning “small” and “skopeîn” meaning “to look at or see,”.

Microscope

A microscope is a laboratory instrument used to examine objects (biological specimens) which are too small to be seen by the naked eye. The microscope must accomplish three tasks:

• Magnification- to provide a magnified image of the specimen.

• Resolution- to separate the details in the image.

• Contrast- to render the details clearly visible to the eyes.

Although we will tnroduce to you the different types of microscopes used for different speciments, our main focus is to discuss about compound microscope, which is commonly used in the laboratories. Compound microscope was developed around the beginning of 17th century.

A variety of glassware like burettes, pipettes, measuring cylinders, flasks, separating funnel etc. are used for experimental purposes in a laboratory. All of these need to be used and handled correctly, otherwise the chances of experimental error and damage to the glassware increase significantly. Being made of glass, they need special care while washing and using in experiments because even a minor mistake in handling of glassware may result in breakage of the apparatus. With this precautionary note, let us discuss about some of the specific glassware used in the laboratories.

Burette

Burette is a long graduated glass tube with a stopcock at one end for delivering a known/desired volume of a liquid, especially in titration experiments. It contains a stopcock at the lower end and a tapered capillary tube as the stopcock’s outlet. The flow rate of liquid from the tub stopcock’s outlet can be controlled with the help of stopcock valve. Burette is used for measuring the volume of a solution/chemical added in a quantitative (titrimetric) estimation experiment.

Procedure of using a Burette

The burette reading must be noted before and after delivering the chemical/ solution from the burette. The difference in these two readings is the volume of the chemical/solution released out of the burette. The solution should be released slowly/drop-by-drop to avoid any experimental error/mistake. If the solution/chemical is allowed to pour out too fast, the wall of the burette will not drain properly and some liquid may remain sticking to the surface of the walls. Moreover, excessive amount of chemical may be released/dropped during the experiment, particularly during the titration experiment wherein we need to know the exact amount of acid/base needed to get neutralization point. Thus, any minor mistake may lead to get a faulty reading. The measuring capacity of a burette usually used in a laboratory is 50 mL.

Since mouth pipetting of liquid reagents in a laboratory is not advisable, different tools are needed for safe, easier, and precise dispensing of liquid reagents. This chapter is devoted to make you aware of the tools like vacupette and micropipette which can be used for the handling of liquid reagents in a safe and precise way.

Vacupette

Glass pipettes have been traditionally used by sucking liquid solvent/solution directly using mouth. For safety reasons, mouth pipetting is no longer permitted in a laboratory. Hence, to fill a pipette vacupette is used by placing it on the top of glass or plastic pipette. It acts as a device to create vacuum for filling reagent in the pipette as well as for releasing the reagent with mechanical regulation on the flow out of the liquid. Vacupette can be of different types.

1. Rubber Bulb Vacupette

Rubber bulb vacupette is often used to transfer (pump up and discharge) liquid using a pipette when a larger quantity of chemicals is to be transferred. Small/tiny rubber bulb is attached to glass/plastic pipette for drawing little amount of reagents. Small vacupette is used to precisely discharge smaller volume/ drops.

Handling of Vacupette

• Insert the top of a pipette in the bottom of the rubber bulb vacupette (Figure 6.1).

• Remove air from the pipette by squeezing valve “A” at the top of the vacupette while simultaneously squeezing the rubber bulb. The amount of air released depends on the size of the rubber bulb.

The concept of value, expressible in the metric units by which the character is measured. The value observed when the character is measured on an individual is the phenotypic value of that individual. All observations of means, variance, or covariances, must clearly be based on measurements of phenotypic values. In order to analyse the genetic properties of the population we have to divide the phenotypic value into two componants.
The first division of phenotypic value is into components attributable to the influence of genotypic and environment. The genotype is the particular assemblage of genes possessed by the individual, and the environment is all the non-genetic circumstances under the term ‘environment’ means that the genotype and the environment are by definition the only determinants of phenotypic value. The two components of value associated with genotypic value and the environmental deviation.
The mean environmental deviation in the population as a whole is taken to be zero. So that the mean phenotypic value is equal to the mean genotypic value. The term population mean than refers equally to phenotypic or to genotypic values. When dealing with successive generations we shall assume for simplicity that environment remains constant from generation to generation so that the population mean is constant in the absence of genetic change. If we replicate thea particular genotype in a number of individuals and measure them under environment conditions normal for the population, their mean environmental deviations would be zero and their mean phenotypic value would congiguently be equal to the genotypic value of that particular genotype.
In principle it is measurable, but in practice it is not, except when we are concerned with a single locus where the genotypes are phenotypically distinguishable or with the genotypes represented in highly inbred lines for example, considering a single locus with two alleles. A1 and A2, we call the genotypic value of one homozygote + a, that of the other homozygote – a and that of the heterozygote d (we shall adopt

The amount of variation is measured and expressed as the variance. When values are expressed as deviations from the population mean the variance is simple the mean of the squared values. For example, the genotypic variance is the variance of genotypic values and the environmental variance is the variance of environmental deviations. The total variance is the phenotypic variance of the variance of phenotypic values, and is the sum of the separate components. 

Variation in Chromosome Structure

Natural variation exists in chromosome structure

Changes in chromosome structure include deletions, duplications, inversions, and translocations

The loss of genetic material in a deletion tends to be detrimental to an organism

Duplications tend to be less harmful than deletions

Duplications provide additional material for gene evolution, sometimes leading to the formation of gene families

Copy number variation is relatively common among members of the same species

Comparative genomic hybridization is used to detect chromosome deletions and duplications

Inversions often occur without phenotypic consequences

Inversion heterozygotes may produce abnormal chromosomes due to crossing over

Translocations involve exchanges between different chromosomes

Individuals with reciprocal translocations may produce abnormal gametes due to the segregation of chromosomes
