ROLE OF CIRCADIAN CLOCK GENES IN THE REGULATION OF CELL CYCLE PROCESSES

One  interesting  branch  of  biochemistry  which  scientists  are  still  trying  to completely  unravel is the  area  of  chronobiochemistry.  The  history  of  chronobiology  is  dated  400  B.C.,  when  Androsthenes observes  that  leaves  of  certain  trees  open  during  the  day  and  close  at  night.  It  was  only  recently  that the  first  human  clock  gene  was  discovered.  All  living  organisms  possess  an  internal  bio...

Effect of edible camphor administrations on levels of steroid and thyroid hormones in male wistar rats_content_1

ABSTRACT Background:  Edible  camphor  (EC)  is  one  of  the  ingredients  in  the  preparation  of  local infusion  for  the  management  and  treatment  of  pile,  back  pain,  and  erectile  dysfunction, which  are  practices  commonly  in  the  south-western  part  of  Nigeria.  Methods:  Thirty  rats  were  used  for  the  study,  and  were  divided  into  six  groups  of  five rats  each.  Group  I  animals  served  as  normal  ...

Design and Implementation Of E-Library System (A case study of University of Port-Harcourt)

ABSTRACT Libraries have been an important part of educational and information sector of any school or community. The success of any library largely depends on proper management. Several libraries have suffered failure as a result of inadequate management and incapacitations in handling sensitive information as regards members of the library.  This research therefore, aimed at developing a digital library system, which will help direct and position library to meets its ever increasing deman...

THE EFFECT OF ABATTOIR EFFLUENT ON PHYSICOCHEMISTRY AND BACTERIOLOGICAL ANALYSIS ON KARU RIVER, ABUJA (CASE STUDY: KARU ABATTOIR)

The impact of Sewage and Abattoir effluent discharge into river resulted in water pollution there by reduces it quality.This study aimed at analysing the physicochemical and bacteriological parameters of Karu Abattoir effluent and Sewage discharge into Karu River in FCT ,Abuja, Nigeria in order to ascertain the quality and impact on Karu River. Four water samples along with one effluent ample were collected aseptically and subjected to standard microbiological and physicochemical analysis

Heterocyclics Compound Effects in Crude Oil

PREFACE Crude oil is a naturally occurring brown to black flammable liquid which is composed of hydrocarbon compounds, non hydrocarbon compounds, organometallic compounds. Various types of non hydrocarbon compounds present in crude oil are organic sulfur, nitrogen and oxygen compound. Traces of this compound causes problem to catalytic refining process in the refining industry. Hydro treatment process is used to eliminate the problems caused by this compound TABLE OF CONTENT  Abstract  CHAP...

Role of mitochondria in apoptosis

In  living  cells,  especially  eukaryotes,  mitochondria  involvement  appears  to  be  important in  the  general  status  of  every  aspect  of  life.  Apoptosis  as  a  programmed  cell  death  is  mandatory to  all  life  process  thus,  mitochondria  might  be  describe  as  organelles  that  serves  as  a  gatekeeper to  trap  a  variety  of  proapototic  protein  and  prevent  the  functions  of  this  proteins  in  the  cytosol...

GENETICS OF EPILEPSY

Genetics is a huge and growing area across human biology, medicine and science, providing information about basic processes from birth to death, from development to degeneration, and in even revealing enough about disease biology to lead to new therapies or better use of existing treatments because gene activity underlines all biological process (Sisodiya, 1881; Vadlamudi et al., 2014).  Epilepsy is defined as one unprovoked (or reflex) seizure and a probability of further seizures similar t...

Bio-prospective Screening of Antibacterial and Phytochemical Activity of Caesalpinia pulcherrima.Linn (Pride of Barbados) on Selected Clinical Isolates

This work was carried out to evaluate the antibacterial and Phytochemical activities of Caesalpiniapulcherrima  leaf and stem bark on some clinical isolates. The plant parts were collected from St. Benedict Catholic Church premises, Owena Barracks, Akure, Ondo State. Crude ethyl acetate extracts of Caesalpinia pulcherrima leaves and stem bark was assayed for its antibacterial activity against Staphylococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa, Bacillus subtilis, Escheric...

Prospects of Essential Oils in Drug Discovery

Abstract Essential oils (EO), according to the International Standard Organization (ISO)  defines essential oil as the product obtained from parts of plants by distillation with water steam and the product obtained by expression from pericarp of medicinal plant. The rapid growth and increase of the knowledge of identification, extraction, purification and characterization of essential oils in most local plant species is fast becoming an important aspect of the drug production process. ...
