The strains and stresses of our modern living, i.e., insecurity, worry, unhappiness, have helped to make mental illness our number one health problem. The twentieth century was often referred to as the “Age of Anxiety”, but the twenty-first century is considered the period of ‘strains and stresses’ as well as ‘hustle and bustle’. These days, psychological burnout and the problem of depression are increasing day by day.

Despite the proximity and enormity of the problem of mental illness and the familiarity and understanding with which we should approach it, attitudes towards it exist in our culture that are very old now, as many people still regard mental illness as they once regarded cancer, polio, and other diseases—as incurable, something mysterious and fearful. Some people still consider that somebody has done magic on these people, or some bad element has entered their bodies.

Virtually, all of us will encounter mental illness at sometimes or another in our lives, either in our own family or in our circle of friends. We consider it a stigma, and we don’t want to reveal this bad omen to others. All these things are related to our mental health. Good mental health leads to mental hygiene. So, it is important to know what mental hygiene is and how to inculcate the different aspects of mental hygiene.

Positive psychology plays a pivotal role in the well-being of adolescents by addressing their strengths and nurturing a growth mindset. It emphasises cultivating resilience, fostering optimism, and instilling gratitude rather than focusing on challenges only. This approach aids young individuals in developing a positive outlook on life, thereby enhancing their mental well-being and overall sense of contentment. By prompting to enhance their strengths, positive psychology equips them with the necessary skills to navigate obstacles and setbacks, resulting in enhanced academic achievements, stronger social connections, and heightened self-confidence. Essentially, it transforms potential hindrances into opportunities for personal growth and prosperity.
The well-being of adolescents is significantly affected by the domestic environment, underscoring the paramount importance of parenting. Parenting is often perceived as an inherent aptitude, typically acquired from one’s parents and through firsthand experience in child-rearing. Despite divergent perspectives on what constitutes ‘effective’ parenting, child psychologists universally acknowledge its pivotal role in fostering robust development, social integration, academic achievement, and self-assurance. Authoritative parenting – characterized by a blend of parental authority and profound attentiveness to the child’s needs – is widely regarded as the optimal approach to nurturing psychologically resilient children (Baumrind, 1991, 1993).

Mental wellbeing in youngsters is not merely the absence of mental illness; it encompasses a state of positive psychological functioning, where individuals are able to manage their emotions, build healthy relationships and navigate the challenges of life. This period is characterized by significant physical, emotional and cognitive development, making it a critical time for establishing the foundations of mental health.
Mental wellbeing is a crucial aspect of overall health, especially during the formative years of childhood and adolescence. In the contemporary scenario, for youngsters, the journey to mental wellbeing is a complex interplay of biological, psychological and social factors. This journey is increasingly shaped by rapid societal changes, technological advancements, academic pressure, family dynamics and global crisis such as the COVID-19 pandemic. These influences have profound implications for the mental health of young people, making it essential to explore the current challenges and opportunities in promoting mental wellbeing among this demographic.
Psychological Development During Adolescence
Adolescence is a time of significant psychological change, marked by the development of identity, self-concept and emotional regulation. During this stage, youngsters begin to form their own beliefs and values, separate from those of their parents or guardians. They also develop the capacity for abstract thinking and moral reasoning, which allows them to engage with complex social issues and make independent decisions. These developmental processes are influenced by a range of factors,

Defining Wellbeing
The notion of wellbeing is not new, it is much more difficult to come up with a consensus definition since the phrase is frequently ill-defined and under-theorized (Camfield, Streuli & Woodhead, 2009). The problem of definition inconsistency is exacerbated by the fact that the phrases “wellbeing” and “happiness,” “flourishing,” “enjoying a good life,” and “life satisfaction” are frequently used synonymously, although having quite different connotations.
Defining wellbeing is tough because it's talked about in many different ways across local and global media, literature, and daily conversations. So many voices, so many angles. But that makes the journey of understanding it all the more fascinating! At first, there were two distinct schools of thinking on wellbeing: hedonic and eudemonic. From a hedonic perspective, happiness is defined as the sum of all happy experiences.
Philosophers like DeSade, Bentham and Hobbes defined wellness as the “pursuit of sensations and pleasure” Hobbes as “a pursuit of human appetites,” and Husain (2008) as “the good society is built through maximizing pleasure and self-interest.” Being loyal to one’s inner self and having a eudaimonic viewpoint on wellbeing are synonymous with the concept of eudaimonia. Maslow (1970) developed a notion of self that builds upon the eudaimonic idea of wellbeing. The conditions that exist in life and the ways in which a person or community makes use of those situations directly affect the quality of life that an individual or community experiences. Wellbeing has become “something everyone seemingly aims for and arguably has a right to,” according to McCallum and Price (2016).

In today’s world, where youngsters face inevitable stress and pressure, wellbeing has gained significant importance. Since research began in the field of mental wellbeing, psychologists have increasingly focused on ‘quality and satisfaction of life,’ making it a popular topic. Quality of life and life satisfaction measure an individual’s perceived level of psychological wellbeing, wellness and happiness, often used interchangeably with subjective or general wellbeing. Mental wellbeing can be described as the overall mental state of an individual who is well-adjusted to their environment. This includes feelings of contentment, enjoyment, happiness, satisfaction with life experiences, job satisfaction and a sense of achievement and belonging. Additionally, it encompasses the ability to manage grief, distress, dissatisfaction, fear or worry in personal and social life. Due to the difficulty in objectively measuring these parameters, the term ‘subjective’ or general wellbeing is emphasized. This concept generally promotes a subjective sense of wellbeing, influencing individuals’ attention to self-care and emotional wellbeing.
Researchers studying subjective or general wellness often view it as a multi-faceted domain rather than a single construct (Pavot and Diener, 2003). Diener, Suh, Lucas and Smith (1999) define subjective wellness as a broad category that includes people’s emotional responses, domain satisfaction and overall life satisfaction. The concept of wellness encompasses both physical and mental health, as well as moral and ethical values. Life is not always smooth; people encounter failures, frustrations and disappointments. It is the mental strength and wisdom of a person that helps them move forward and emerge from life’s occasional darkness to achieve wellness. Maintaining mental balance amid life’s difficulties is crucial for achieving one’s goals.

Cabbage semilooper: Thysanoplusia orichalcea :Noctuidae

Eggs are laid singly on lower surface of leaves.  The emerging larvae feed as a scraper initially and then feed voraciously on the leaves. The larva is greenish and hence not easily noticed initially. But when patches of damage occur in the crop, examine for the larvae and remove and destroy all the larvae. Chemical control is not advisable, and spraying extracts of other aromatic plants can deter egg laying very well.

Abstract

Mentoring is a personal enhancement strategy through which one person facilitates the development of another by sharing known resources, expertise, values, skills, perspectives, attitudes and proficiencies. The concept of mentoring is not new. Guru – Shishya traditions in every old civilization are the examples of mentoring by which culture, technology and knowledge have been successfully disseminated from older generation to newer generation. Being an important career building factor, now more emphasis is given to develop mentoring relationship in organization level. In office culture mentoring facilitates an environment in which an individual grows both as a person and as a professional.

Mentoring represents a developmental relationship between a more experienced individual and a less experienced person, characterized by guidance, support, and knowledge transfer that facilitates personal and professional growth. The word “mentor” originates from Homer’s epic poem “The Odyssey,” where Mentor serves as a wise counselor and guide to Telemachus during Odysseus’s absence. This classical reference captures the essence of mentoring as a relationship built on wisdom sharing, guidance provision, and developmental support that extends beyond mere instruction or supervision.

Contemporary definitions of mentoring emphasize its multifaceted nature as both a relationship and a process that serves developmental functions for mentees while often providing reciprocal benefits for mentors. Kram’s seminal work defines mentoring as a relationship between a young adult and an older, more experienced adult that helps the younger individual navigate the adult world and the world of work. This definition highlights the developmental and navigational aspects of mentoring while recognizing the experience differential that typically characterizes these relationships

Abstract

Oolichan (Thaleichthys pacificus), a small anadromous smelt also known as “savior fish”, were a necessity of life for Pacific Northwest Coastal and adjacent interior indigenous peoples, as they were the first fish to return to the rivers after winter and produced not only tasty flesh but also a nutritious oil, or “grease.” A focus of the traditional oolichan culture is the Nass River of northwestern British Columbia, Canada. The valleys and mountains surrounding the Nass River are the traditional homelands of the Nisga’a people, whose technological innovations including implements, buildings, and landscape structures facilitated fishing, production, and preservation of oolichan, as well as salmon. Over thousands of years, the Nisga’a developed plant-based technologies for use in the oolichan fishery and for preparation trade of rendered oolichan “grease”. In turn, structures and implements associated with the oolichan fishery facilitated knowledge exchange across generations, since the oolichan processing areas and fishing camps were the places where elders conveyed their cultural and ecological knowledge to younger people. Structures fashioned from plants helped people to recall the stories, traditions,

Every organ and tissue of the body is more or less affected by this powerful drug; it transforms healthy cells into inflamed and necrotic cells; decomposes the blood producing a profound anaemia. This is converted into useful life saving and life preserving service if employed homoeopathically, guided by its clear-cut symptoms. The lymphatic system is especially affected with all the membranes and glands, and internal organs, bones, etc. lesions produced by Mercury are very similar to those of syphilis. Very often indicated in the secondary stage of syphilis where there is a febrile chloroanaemia, rheumatoid pains around joints, etc. all mercury symptoms are worse at night, from warmth of bed, from damp, cold, rainy weather, worse during perspiration. It is also known as human 'thermometre'. Sensitive to heat and cold. Breath, excretions and body smell foul. Tendency to pus formation, which is thin, greenish, putrid, streaked with thin blood.

In R there is facility of reshaping the data. Reshaping of data includes joining of two or more vectors to create a data frame. Also two or more data frames can be merged. Appropriate functions are available for these jobs. While merging the data frames, we can join columns or rows.

The process of fracture healing is unique, in which damaged bone restores its original architecture but it does not form a poorly organized replacement matrix, otherwise known as scar tissue, rather it regenerates the original matrix and retains its mechanical properties. In order to repair bone defects, a combination of cells with osteogenic activity and appropriate scaffolding material can stimulate bone regeneration and its repair. A potential substitute for autologous transplantation should possess 3 elements: osteoprogenitor cells, osteoinductive factors, and an osteoconductive scaffold. Stem cells from adult tissues are attractive materials for cell therapy and tissue engineering. These cells generally have restricted lineage potential when compared to embryonic stem cells, and this may be advantageous in certain therapeutic applications. Bone-marrow-derived mesenchymal stem cells (BMSCs) have proven to be beneficial in bone regeneration. Bone marrow stem cells are pluripotent cells with the capability of differentiating osteoblasts so that they have been used to facilitate bone repair. Several studies have shown that seeding of cultured BMSCs on bioabsorbable implants can induce bone formation in vivo and lead to improved healing of critical-size bone defects.

Mesenchymal stem cells (MSCs) because of their self replication and osteogenic differentiation capabilities are regarded as an excellent source of cells for bone tissue engineering. Autologous stem cells are not always preferable since the quality and quantity of such cells will be affected by metabolic diseases, old age, and osteoporosis. Allogenic BMSCs might be preferable to xenogenic, but they are always not readily available. In addition, allogenic MSCs have the potential for carrying some diseases. The use of non-autologous stem cells isolated from healthy donors offers a major advantage since these stem cells can be thoroughly tested and formulated into off-the-shelf medicine in advance. Major attractive advantage of BMSCs as a source of cell transplantation is their low immunogenecity. It is now well established that BMSCs are immune-privileged cells that do not elicit immune responses due to an absence of their immunologically relevant cell surface markers.

Despite the benefits that minimally invasive surgery and osteosynthesis have brought to fracture management and bone healing, there are still many circumstances where bone healing remains challenging. Large bone defects are serious complications that are most commonly caused by extensive trauma, tumour, infection, or congenital musculoskeletal disorders. In nonunion cases repairing of bone defects with composite biomaterials as defect filler can promote bone regeneration. Currently, the gold standard for bone regeneration is use of autogenous bone graft. In order to avoid morbidity at the donor site or if large amount of autogenous bone is needed, bone substitution materials can be used.

Bone substitution materials can be combined with cells such as mesenchymal stem cells (MSCs) to increase bone formation. Bone-marrow derived mesenchymal stem cells (BMSCs) represent an attractive cell population for tissue regeneration. Bone marrow stem cells are pluripotent cells that have been used to facilitate bone repair because of their capability of differentiating into osteoblasts. Several studies on the regeneration of bone have shown that cultured BMSCs, seeded on different bioabsorbable implants are able to induce bone formation in vivo and lead to improved healing of critical-size defects.

Calcium phosphate bone substitutes such as hydroxyapatite (HA) and tricalcium phosphate (TCP) are currently used for bone substitution in many different clinical applications such as repair of bone defects after trauma or tumour and bone augmentation in spinal arthrodesis. Although these bone substitutes are osteoconductive, they often lack the osteogenecity needed to support bone healing in large defects and are slowly degraded in the body. Studies have shown that coating of hydroxyapatite with a calcium silicate layer could encourage cell proliferation and osteogenic differentiation of human bone marrow-derived stromal cells. Silica-calcium phosphate composite in comparison to calcium phosphate-rich biomaterials has a faster resorption rate owing to greater dissolution of Si ions. The use of several growth factors have been studied in bone repair and these factors are known to play a role in differentiation of mesenchymal progenitor cells specific lineages like endothelial cells or osteoblast. Bone morphogenetic protein-2 (BMP-2) has been shown to accelerate bone healing in humans and animal models. BMP-2 acts by osteoinduction and is involved in the differentiation of mesenchymal progenitor cells into osteoblasts. The addition of recombinant human BMP (rhBMP-2) to a self-cross linkable cellulose hydrogels/biphasic calcium phosphate granules construct promotes bone regeneration in a critical-size segmental defect model of non-union in dogs. It is also reported that protein, insulin-like growth factor (IGF-1) stimulates direct migration of human mesenchymal progenitor cells (MPC) and contributes to the recruitment of MPC in bone formation and bone healing.

A. Mesta diseases

1. Anthracnose

Occurrence & severity status

Mesta (Hibiscus cannabinus) is very much prone to be attacked by anthracnose disease (Singh, 2014). It is very destructive disease in India (Ghosh, 1983). The disease also occurs in South Korea with overall disease incidence of 20%. (Kwon et al., 2015).

Symptoms

Symptoms on kenaf plants include dark brown spots on the leaves, petioles and stems. New leaves and shoots are most susceptible to infection (Kwon et al., 2015). Initially the terminal bud is attacked, where stipules and young leaves are affected and develop necrotic spots and withers (Singh, 2014). Mature lesions on fully expended leaves are dark brown and often irregular in shape, and not vein delimited. Later, the infected leaves fall off; Flowers and seed capsules are also affected by the disease (Singh, 2010). The stems are affected in patches. On stem the lesions are elongated and black, which later form cavities and in severe cases, stem-dieback or wilt occurs (Singh, 2010; Kwon et al., 2015).

Abstract

Meta analysis quantitatively summarizes the findings of a large collection of individual experiments. It is a powerful statistical tool since it integrates a vast literature and thus includes large sample size. It leads to a stronger conclusion than traditional literary review as studies are analyzed applying statistical methods. Meta- analysis is increasingly being applied in different fields of biological sciences. It has been emerged as an independent subfield of modern health science researches as in this field very few studies achieve statistical power in isolation. Meta- analysis has also become an integral part of plant science research, e.g., agricultural research, ethnobotanical research, tea and health science research etc. Meta-analysis has few limitations although rigorously conducted meta- analyses are considered more valuable than any single study contributing to the analysis.

Introduction

Production of consumer preferred varieties of fish and fish products have been facing several constraints. Identification of potential constraints is important for growth and development of fisheries sector. The constraints of production and marketing have been examined by a number of researchers in different time and place. In this chapter, it is tried to explain an overview of the different constraints of production and marketing of fish and value added fish.

Constraints of production of freshwater fish

Constraints of aquaculture production in developing countries have been identified by Lee (1997) and categorized them as:

1. natural and environmental (inequitable allocation of land resources, insufficient quantity and degraded quality of water, highly seasonal variation in temperature and natural disaster);
2. socioeconomic (insufficiency of infrastructure for production and marketing, variation of prices of inputs, ageing and poor training of aqua-farmers); and
3. Institutional constraints (inefficiency of extension services, lack of a better organization of producers, shortage of rural finance).

15.1. Introduction

Meta-analysis is a statistical technique used to combine the results of multiple studies to produce a single, more precise estimate of the effect size of a particular intervention or association. It is a powerful tool in research, particularly in f ields such as medicine, psychology, education, and social sciences, where it is often necessary to synthesize evidence from numerous studies to draw meaningful conclusions. This chapter provides a comprehensive overview of meta-analysis, including its history, methodology, advantages, limitations, and applications.

15.2. Historical Background

The concept of meta-analysis dates back to the early 20th century, but it was not until the 1970s that the term was coined by Gene V. Glass. Glass defined meta-analysis as “the statistical analysis of a large collection of analysis results from individual studies for the purpose of integrating the findings” (Glass, 1976). Since then, meta-analysis has evolved significantly, with advancements in statistical methods and software making it more accessible and robust.

15.3. The Need for Meta-Analysis

15.3.1. Accumulation of Evidence

In many fields, particularly in medicine and psychology, a large number of studies are conducted on the same or similar research questions. However, individual studies may have small sample sizes, leading to low statistical power and inconclusive results. Meta-analysis allows researchers to pool data from multiple studies, increasing the overall sample size and statistical power, thereby providing a more reliable estimate of the effect size.

ìMetabolic Diseasesî mean the diseases that occur due to the ìimbalance between the rate of input of dietary nutrients and the ìoutput of productsî (product like new born, milk for young one etc.) and lead to the occurrence of metabolic derangements in the affected wild animal species.

Management of metabolic diseases depends on an early diagnosis. For an early diagnosis, metabolic profile test (MPT) is a diagnostic tool being commonly used in veterinary practice, particularly for dairy herds, to assess the metabolic health of the animals. It helps in an early detection by measuring various blood parameters that indicate the nutritional and health status of the cows for their effective timely management. MPT is based on the principle that the imbalance between input (feed) and output (production) is reflected in the abnormalities of key metabolites in the blood.
