Amino acids are essential components of all living cells as building blocks of proteins. They are also metabolically active and supply substrates for many other biochemical reactions. In a bacterial cell, about 0.4% of the dry weight is amino acids. The amino units in other living systems varies according to species, age and part of the body.

Amino acids are organic molecules made up of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). However, sulfur (S) and selenium (Se) are also found in some cases. Amino acids are essential organic compounds that come together to create proteins, thus making them the fundamental building blocks of proteins. These biomolecules play vital roles in various biological and chemical processes within the human body and are essential for the growth and development of an individual.

Amino acids consist of an acidic group (-COOH), a basic group (-NH2 ), and a side chain (R) or a hydrogen (H) atom, all bonded to the carbon atom. The features of amino acids are due to the side chain because they differ only in their side chain. All amino acids have the same basic structure except proline, which has a cyclic structure.

Various forms of amino acids like alpha (α), beta (β), gamma (γ) or delta (σ) form are found. The position of the amino group (-NH2 ) determines the form of the amino acid, i.e., if the NH2 group is attached to the α-carbon, it is called α-amino acid; if β-carbon, it is called β-amino acid, and so on. Mostly, α-Amino acids are found as the numbering of amino acids is done from the carboxylic group (-COOH).

Amyloid

• Amyloid (G. Amylon; Amyl(o) - STARCH) means starch-like.

• Amyloid is a pathologic glycoprotein deposited in the extracellular spaces and forms fibrils on polymerization.

Histological characteristics

• Amyloid is specially stained with Congo Red.

• Under polarized light, green birefringence is noticed because of alignment of fibrils.

• Amyloid fibrils are 7.5 to 10 nm in diameter, rigid, non-branching hollow-cored tubules of unknown length.

• β-pleated sheet configuration is seen in X-ray diffraction.

• The P-component which is a glycosa-amino-glycan (GAG) facilitates polymerization of amyloid.

Veterinary anatomy is a backbone as well as basic discipline in the veterinary sciences at large. The new entrants of the first professional year of B.V.Sc. & A.H. get more exposure in gross anatomy, histo- architect models and developmental anatomy of their current curriculum in our country.
Laboratory demonstration plays a vital role module in virtual teaching and learning program of their better understanding of the subject. The visualization and memorization is the basic requirement for thorough understanding of the anatomy of the individual in medical sciences. The various method of teaching have been debated because it has own limitations. To improve the anatomical understanding the traditional way of using cadavers but with current scenario of restrictive laws which implemented by Veterinary Council of India (VCI) and other organizations viz, SPCA, PFA, CPCSEA/IAEC etc. The scarcity of specimens which are invited the other alternative way of keeping and preserving the specimens for laboratory teaching. Under the unusual circumstances, the normal conventional method of cadaver/specimen/organ preservation should be replaced by the advanced technologies for easy and interesting to learn. In the traditional curriculum method of anatomical specimens taught and learned by formalin fixed cadavers/specimens/tissues. Since, the conventional method creates health problem due to extensive use of formalin as preservative chemical for cadaver preservation. This method of preservation causes wet slippery tissues, respiratory irritation, topical allergic reactions, and students should wear gloves to protect themselves from the fixative like formaldehyde (act as a potential carcinogenic agent). However, the anatomists have been challenged for an alternative laboratory teaching aids in near future. In recent past, the alternative method has developed teaching materials by the innovative novel techniques like Plastination, corrosion cast, pneumatic air dried specimen etc.

ABSTRACT

A low molecular weight antifungal protein has been purified from the leaves of a medicinal herb, Mentha viridis, L. using a combination of cold acetone precipitation, carboxymethyl cellulose column, Q-sepharose column chromatography, and preparatory native PAGE techniques. The purified protein migrated as a single band on SDS-PAGE, with a molecular weight of ca 15.5 kDa. The purified leaf protein of M. viridis inhibited mycelial growth of phytopathogens such as Fusarium solani, Fusarium sp., and Pythium aphanidermatum. The purified protein from the leaves of M. viridis inhibited the growth of human pathogens such as Candida albicans and C. tropicalis (75 mg/mL). This inhibition is concentration dependent. The purified antifungal protein of leaves of M. viridis did not show protease, chitinase, and b-1, 3 glucanase activity.

Vegetables constitute about 55 per cent of horticultural crop production in the country with a total production of 85 million tonnes which is estimated to cross 100 million tonnes in near future. Successful cultivation of vegetables is hampered due to the incidence of several insect pests. Cultivation of hybrids, improved varieties, intensive agronomic practices, off season cultivation and indiscriminate use of insecticides has changed the pest complex in these crops.

Introduction

In Puducherry, the first KVK was founded in 1974. In the newly constructed districts and several larger districts, 106 additional KVKs will be established, bringing the total number of KVKs to 645. KVKs are approved for use by Agricultural Universities, ICAR Institutes, associated Government Departments, and Non-Governmental Organizations (NGOs) engaged in agriculture. The KVK initiative is fully funded by the Government of India. KVK, which is a crucial component of NARS, aims to evaluate location-specific technology modules in agricultural and related companies through technology assessment, refinement, and demonstrations. As a knowledge and resource centre for agricultural technology, KVKs have supported public, private, and non-profit sector efforts aimed at enhancing the district’s agricultural economy(1).

The KVK’s mandate has changed from vocational training to technology assessment and demonstration for its application and capacity building in a district in preparation for its growing contribution to NARES in India. Though technologies were developed at ICAR Research Centres or State Agricultural Universities, KVK carried out location-specific technology assessments, micro location refinements on farms with genuine problems, and final technology certification for widespread adoption by farmers(2).

Throughout the history of Indian agriculture, the contribution of farmers to agricultural technology development and dissemination has been very significant. Farmers’ practices are useful not only for scientific technology development, but also for sustainable agricultural development. Rural economy will sustain only when it effectively utilise the available local resources. But recent agricultural development witnessed that those modern agricultural practices slowly replacing the farmers’ practices. In this juncture the basic challenge for sustainable agriculture is to make better use of these internal resources. This can be done by minimizing the external inputs used, by regenerating internal resources more effectively or by combinations of both (Rolling and Pretty, 1997).

Taxonomic Classification of Common Livestock Species

A series of terms (kingdom, phylum, class, order, family, genus, species etc) is used to denote the member of a kingdom and each division of the hierarchy contains one or more groups from the next lower division like subphyla, subclasses, suborders, subfamilies, or subgenera etc if required. Further, species may be subdivided into varieties, breeds, or strains. Domestic farm animals belong to either class Mammalia or Aves. The scientific name of an animal comprise of its genus and species names. The first letter of genus name is written in capital letter but not the species name. While writing the scientific name of an animal the genus and species names are underlined when handwritten and always italicized when printed. General characteristics and taxonomic arrangements of common domestic animals have been given below.

Kingdom : Animalia

Members of kingdom Animalia are multicellular, eukaryotic heterotrophs. Adult animals develop from embryos. Most animals ingest and digest their food in some kind of internal cavity.

History

Pauling and his colleagues coined the phrase "molecular disease" in 1949, based on their finding that a single amino acid shift in the β-globin chain causes sickle cell anemia, which is characterized primarily by repeated bouts of acute pain due to vessel occlusion. In theory, their discoveries laid the groundwork for molecular diagnoses, though the major breakthrough came many years later. At the time, when molecular biology was only rapidly growing, providing molecular diagnostic services was unthinkable and practically impossible. In the early days of recombinant DNA technology, many scientists from different f ields collaborated to provide the first seedlings of molecular diagnostics.

INTRODUCTION

Ideas and knowledge are increasingly important parts of trade. Most of the value of new medicines and other high technology products lies in the amount of invention, innovation, research, design and testing involved. Hence, protection of such values is paramount. This paper details how these values are protected in India.

Introduction

Milk is regarded as the “ideal food” as it contains nutrients necessary for both newborns and adults (Azad & Ahmed, 2016). It is high in protein, fat, carbohydrates, vitamins, and minerals. Unfortunately, milk is easily adulterated all over the world for several reasons, including a gap between supply and demand, the inherent nature of milk which can imbibe many adulterants that are difficult to identify, the low purchasing power of consumers, an insufficient share of the organized sector in the dairy business, and, most importantly, a lack of efficient and rapid methods for detecting adulterants (Ellis et al., 2012; Moore et al., 2012).

Introduction

Modern intensive livestock and poultry production has achieved phenomenal gains in the efficient and economical production of high quality and safe animal products and by-products. Furthermore, the overall performance of livestock can be increased by improving nutrients utilization, health status, fertility and efficiency of production. The use of feed additives has been an important part of achieving efficient livestock production. Feed additives are non-nutritive substances, preparations and micro-organisms that are added to animal feed to improve productive, reproductive and health performances. Any substance is considered as a feed additive when, not having a direct utilization as nutrient, is included at an optimum concentration in diet to exert a positive action over the animal health status or the dietary nutrient utilization. Hutjens (1991) defined feed additives as a group of substances that can cause a desired animal response in a non-nutrient role, such as pH shift, growth, or metabolic modifier. Feed additives are added deliberately to animal feed which may favourably influences characteristics of the animal feed, feed intake, gastro-intestinal flora, digestibility of the animal feeds, animal production, health, fertility and characteristics of animal products. Because of their chemical nature as active principles, additives are generally included in very small proportions in diet.

Helminths include the nematodes (roundworms), trematodes (flukes) and the cestodes (tapeworms). The adult worms live in intestine and discharge the eggs or larvae that comes out with the faeces. Therefore, diagnosis is based on the detection of eggs or larvae in faecal samples.

Overview of Nematode infections in humans and animals

The phylum Nematoda, (roundworms), is the second largest phylum in the animal kingdom, encompassing up to 500,000 species. Members of Nematoda are elongated, with bilaterally symmetric bodies that contain an intestinal system and a large body cavity. According to a report approximately 60 species of roundworms parasitize humans. Intestinal roundworm infections constitute the largest group of helminthic diseases in humans. According to 2005 report of World Health Organization (WHO), approximately 0.807-1.221 billion humans suffers from ascariasis, 604-795 million from trichuriasis and 576-740 million from hookworm infections worldwide.

Introduction

Global warming is chiefly due to combustion of fossil fuels for multifarious energy needs, causing emission of greenhouse gases which trap energy from the sun leading to warming. These climate changes bring in variation in patterns and emergence of new zoonotic diseases to newer areas. These changes sometimes create conducive conditions for the propagation of insect vectors. History shows that most of the diseases have a direct correlation with climatic changes. The survival and propagation of pathogens are directly related to temperature and humidity etc. Extreme shifts in weather patterns resulting from global warming and climate changes adversely affect the ecosystem resulting in new diseases, re-emergence of earlier diseases including emergence of zoonotic diseases. The emergence of the new cholera strain O: 139 and outbreaks of Dengue, West Nile virus and Rift Valley fever in newer and non-endemic areas have been linked with the El Nino effect. The spread of disease agents may be facilitated by factors including environmental conditions, the presence and availability of suitable hosts, the arthropod's feeding behavior and host preferences.

INTRODUCTION

Indigenous knowledge is the knowledge of the indigenous people inhabiting different geographical regions of the world with their own language, culture, tradition, belief, folklore, rites and rituals. In course of their close interactions with nature and natural resources, they are to make a certain decisions as to solve their problems they encounter in their day to day life while managing the land and environmental resources for survival.

Several researchers explained traditional knowledge as holistic, encompassing many fields of scientific knowledge, such as climate, hydrology, soils, plants and animals (Howes and Chambers, 1980, Jungerius, 1985, Wilken, 1987, Agrawal, 1995). Therefore, indigenous knowledge so developed is based on necessities, instinct, curiosity and observations of ethnic groups to mitigate the immediate problems. Several logical observation was used by them in the decision making process as to how, when and where to act depending on the situations.
