    Abstract [+]

    Transcriptomics has allowed for a better understanding of disease, and the sequencing of individual genes is becoming a leading approach to discovering novel germ lines. A newly defined cell type, described as transitional cells, was characterized based on their expression of key marker genes that define principle cells (PC) and intercalated cells (IC). Gene expression patterns suggested that a Notch signaling pathway was activated during the transition from IC to PC. An experimental model studying the transition in an inducible transgenic mouse demonstrated that Notch signaling and receptor expression is sufficient to drive cell transition in differentiated adult kidney collecting tubule. The identification of novel cell lines allows for a more accurate diagnosis of kidney disease and precise staging of disease. Molecular profiling and precision therapy will continue to revolutionize the field of medicine and warrants further exploration.

    Abstract [+]


    There is a global increase in occupational exposure to solvents, some of which are suspected to cause acute or chronic toxic nephropathies in humans. However, limited studies have been done to evaluate the systemic effects of exposure to some of the commonly used solvents such as paints.


    The aim of the present study was to assess the effect of chronic exposure to paint fumes on renal and hepatic functions of industrial spray painters. Methodology In this cross-sectional study, 49 occupationally exposed male industrial spray painters who had served for greater than 5 years were evaluated for changes in renal, hepatic and hematological indices using standard instruments and results were compared with levels in the unexposed (sex and age-matched) participants.


    Significant changes in markers of renal, hepatic and hematological functions were observed in the exposed compared with unexposed participants including significant decrease in estimated glomerular filtration rate (eGFR) and serum levels of potassium (K+) and chloride (Cl-), and significant increases in serum levels of creatinine (Cr), sodium (Na+), urea (Ur) and uric acid (UA) in the exposed compared to levels in the unexposed group. Abnormal serum levels of hepatic enzymes (AST, ALT and ALP) and hematological indices (PCV, total-RBC, nuetrophils, basophils, monocytes and lymphocytes) were also observed in the exposed compared to levels in the unexposed participants.


    Prolonged exposure to paint fumes may be associated with a significant risk for hepato-renal dysfunction and hematotoxicity. Preventive measures should include limiting exposure and using antioxidant medications.

About the Journal

Nephrology – Open Journal (NPOJ) is a combination of two words, Nephros meaning  “Kidney” and logy means “the study of”. It specializes in kidney care and treating diseases of the kidneys.

Nephrologists are also called kidney doctors. Nephrologists are first trained in internal medicine and then they undergo more training to specialize in treating patients with kidney diseases. They usually treat kidney diseases like Chronic Kidney Disease (CKD), Polycystic Kidney Disease (PKD), acute renal failure, kidney stones, and high blood pressure and are educated on all aspects of kidney transplantation and dialysis.

However, Openventio aims to widespread all the detailed matters related to Nephrology through its Open Journal to all the scientific community for its welfare and also provides invaluable and gratefully acknowledged logistic help for the subsequent international knowledge, experience, and skills as their assets.

Aims and Scope

Nephrology – Open Journal (NPOJ) is dedicated to the open dissemination and robust discussion in the area of nephrology and its related fields. This journal focuses on Nephrology and its related fields.

NPOJ covers a very broad range of topics such as dialysis, tubular/interstitial disorders, glomerular/vascular disorders, hypertension, mineral metabolism, kidney transplantation, management of acute kidney failure.

NPOJ covers a wide array of subjects as given below

  • Dialysis
  • Glomerular/Vascular Disorders
  • Mineral metabolism disorder
  • Pediatric nephrology
  • Urinary bladder cancer
  • Management of acute kidney failure
  • Kidney transplantation
  • Acute kidney injury
  • Polycystic kidney disease
  • Diabetic nephropathy
  • Tubular/interstitial disorder
  • Hypertension and nephrology
  • Glomerulonephritis
  • IgA nephropathy
  • Lupus Nephritis
  • Glomerulus
  • Renal tubules
  • Nephritis
  • Nephrotic syndrome
  • Urinomics
  • Clinical and translational research
  • Clinical trial
  • Epidemiology

Management of nutrition, chronic kidney disease, sonograms, x-rays and other tests.

It also covers a wide spectrum concerning secondary hyperparathyroidism, blood pressure control, diabetic nephropathy, vasculitis, primary glomerulonephritis, transplant immunology, and medical management of the transplanted patient, as well as the micro-inflammatory state in renal failure.

Submissions for this Journal are accepted from the very basic nephrology studies to the advancements in the field. This journal accepts manuscripts based on basic nephrology to advanced nephrology.

The audience of NPOJ includes nephrologists, internal medicine physicians, registered nurses, nurse practitioners, certified physician assistants, pharmacists, social workers, dietitians and all allied healthcare professionals working with patients who have Chronic Kidney Disease (CKD) or End-Stage Renal Disease (ESRD), clinicians, surgeons, nurses, and others.

All types of articles such as original research, review, case-report, mini-review, editorial, short-communication, book-review, opinion, commentary, Letter to the Editor, conference, proceedings, technical report, errata, and illustrations are most welcome for publication in this journal.

We are open to receive comments or any corrections from any potential scientists to improve the quality of our Journal.
