INTRODUCTION

  • DMN is a potent hepatotoxin, carcinogen and mutagen which exerts its carcinogenic effects, causes fibrosis, cirrhosis and induces hepatic necrosis through metabolic activation by CYP2E1 (George et al., 2001; Kasprzyk-Hordern et al., 2005).
  • The occurrence of dietary and environmental chemicals such as DMN in our drinks and foods including fish, meat as well as fresh supermarket products is well established (Okafor and Ogbonna, 2003; Okafor and Nwogbo, 2005; Okafor et al., 2007, Griesenbeck, et…

INTRODUCTION

  • Diabetes mellitus (diabetes) is a chronic condition which occurs when the pancreas does not produce enough insulin, or when the body cannot use the insulin it produces effectively (Kumaran et al., 2014; Dey et al., 2015).
  • Hyperglycaemia, or raised blood sugar, leads to serious damage to many of the body’s systems.
  • Diabetes is also characterized by disturbances of carbohydrate, fat and protein metabolism.

INTRODUCTION

Biomphalaria glabrata is epidemiologically an important snail species host in the transmission of human schistosomiasis in the Caribbean and South American (Reeves, 2008). This chronic and debilitating disease remains one of the most public health concerns in 74 developing countries, infecting more than 200 million people (Tallima, 2013). Intramolluscan development of S. mansoni larval in the Biomphalaria spp is a complex process involving initial infection of the snail host by the free-swimming miracidium, its subsequent transformation to…

The interactions between Schistosome parasites and their intermediate snail hosts at the molecular level are crucial events that determine the success/failure of a parasite's infectivity (Adema et al., 2012; Webster et al., 2016).  The study of such interactions is currently attracting tremendous attention, particularly in relation to the development of strategies aimed at interrupting parasite transmission (Gray et al., 2012; Cantacessi et al., 2013) and hence Schistosomiasis control (Adema et al., 2012). Although, there are many studies designed…

INTRODUCTION

Infectious diseases such as malaria, trypanosomiasis, leishmaniasis, schistosomiasis have huge health, social and economic impact on major populations particularly in endemic regions (Parsons et al., 2015). They are responsible for a high degree of morbidity and mortality. Globally, about 50% of deaths attributed to these diseases occur among the poorest countries of the world (Fuller et al., 2015). In addition, some of these pathogens infect domestic and wild animals, consequently, leading to zoonotic infections (Cook, 2015). Although…

BACKGROUND-AIM
Breast cancer is a heterogeneous disease of about four subtypes with distinct clinico-pathological and molecular features. Information on the serum levels of reproductive and thyroid hormones in the breast cancer subtypes is sparse. This study is aimed at determining the contribution of reproductive and thyroid hormones to the pathogenesis of luminal, HER2+ and triple negative breast cancer subtypes

INTRODUCTION

During data collections in on-farm research, one encounters situations where there are large numbers of variables comprising the dataset. One of the key steps in data analysis is finding ways to reduce dimensionality without sacrificing accuracy. Principal component analysis (PCA) is a multivariate technique in data analysis. It can be used for compressing higher dimensional data sets to lower dimensional ones (Davis, 1986).

INTRODUCTION

Even though the term biochemistry, after about 100 years of use, has become commonplace in our language, a precise definition is difficult and depends on who you ask. Most scientists will agree with the straightforward definition, the study of life at the molecular level. The word ?biochemistry? has two components, biology and chemistry, and students of the discipline must be well versed in the fundamentals of both subjects. Biochemistry can also be defined as:
     ? The science that is…

INTRODUCTION

The major function of carbohydrates in metabolism is as a fuel to be oxidized and provide energy for other metabolic processes. The carbohydrate is utilized by cells mainly as glucose. The 3 principal monosaccharides resulting from digestive processes are glucose, fructose and galactose.

 

Much of the glucose is derived from starch which accounts for over half of the fuel in the diets of most humans. Glucose is also produced from other dietary components by the liver and, to…

INTRODUCTION

Crude oil pollution is a global menace that has caused critical environmental and health defects especially in oil dependent countries (Obayori et al., 2009, Muthuswamy et al., 2008).The disadvantages associated with conventional treatment of crude oil pollution have led to the development of an alternative, more economical and reliable biological approach. This makes the search for crude oil degrading microbes very crucial (Olajuyigbe and Ehiosun, 2016).

The increase in human population has led to a greater demand for food with much concern in the demand for quality protein, Aquaculture to provide protein for man.

Generally, many plant proteins are low in one of the essential amino acids but a combination of plant proteins such as grains with pulse or seeds may give a high quality protein which is just as good as protein from animal foods (Anhwange et al., 2004).

Metabolic syndrome (MS)

MS* is a constellation of interconnected factors which increase the risk of cardiovascular diseases (CVD) and type 2 diabetes mellitus (T2DM) (Kassi et al., 2011). One of the major public health challenges worldwide (Alberti et al., 2005) even, in the developing world where poverty is widespread.

Appropriate intake of micronutrients is required to maintain optimal health. Inadequate intake is recognized as an important contributor to the global burden of disease through increased rates of illness, death from infectious diseases, and of disability such as mental impairment (Ezzati et al., 2002). Deficiencies of micronutrients have been associated with various pathologies such as hypertension

INTRODUCTION

Flocculants, or flocculating agents are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc (1). Thus they are widely applied in different industrial processes, including wastewater treatment, downstream processing, food and fermentation processes (2). Although chemical flocculants have been used widely due to their effective flocculating activity and low cost, some of these synthetic flocculant have threats to public health and increase environmental risks (3).

In recent years, utilization of…

INTRODUCTION

  • Flocculation, in the field of Chemistry, is a process where colloids come out of suspension in the form of floc or flake.
  • According to the IUPAC definition, flocculation is “a process of contact and adhesion whereby the particles of dispersion form larger size clusters”.
  • Flocculation is synonymous with agglomeration, aggregation, and coagulation .

Introduction: Features
• A strain is considered “probiotic” if it proves to be safe
and has some basic features which are:
• acid and bile tolerance,
• ability to adhere to intestinal epithelium,
• antagonistic activity towards pathogenic bacteria (Lin et
al., 2006).
Survival of the intestinal transit and, at least, transient
colonization of the intestine appear to be the main
preconditions for microorganisms to be of any beneficial
effect to the host after consumption (Iyer et al., 2010).

A good biostimulant is not judged based on the biostimulation efficiency to enhance oleophilic microbial growth for hydrocarbon degradation alone but also on the ability to restore crude oil compromised sites to support agricultural activities and diverse microbial functions and regain soil integrity

The functional morphology of the mouth and gastro-intestinal tract of different fish species, revealed to a large extent the type of food and mode of feeding habits of the fish species.
The varieties of dietary items found in the aquatic ecosystem are to a large extent is responsible for the variations in morphological modifications to acquire and utilize the different food item by various species.

INTRODUCTION
•Intestinal helminthiasisare soil transmitted helminthinfections which affect the world’s most impoverished and deprived communities. These infections are associated with poor environmental sanitary conditions (WHO, 2017). They are transmitted by eggs in human faeceswhich tend to contaminate the soil under poor environmental conditions.
•These diseases are also among the neglected tropical diseases which tend to have a high geographical overlap throughout the tropical countries.(Sach, 2007)
