High Concentrations of the Angiogenic Peptide VEGF-A in Seminal Fluid and its Association to Prostasomes.

Clinical laboratory
BACKGROUND: Angiogenesis is the formation of new blood vessels by capillary sprouting from pre-existing vessels. This process is associated with increased expression of angiogenic factors like vascular endothelial growth factor (VEGF). The VEGF famil...

Level of Human Antibodies Targeting HCV E1/E2 Peptides and Spontaneous Clearance of HCV in Blood Donors.

Clinical laboratory
BACKGROUND: Hepatitis C virus (HCV) is a major health problem worldwide particularly in Egypt. The humoral immune response has an important function in the control of HCV infection. The aim of this study was to investigate the role of neutralizing an...

Investigation of serum Ki-67 as a biomarker in tumor-bearing dogs.

Research in veterinary science
Because of the limited number of tumor markers in veterinary medicine, there is need for identifying new markers. Ki-67 has been investigated as a tissue marker of malignant alterations. We hypothesized that Ki-67 would also be measurable in serum an...

Nanobody-based enzyme immunoassay for ochratoxin A in cereal with high resistance to matrix interference.

Talanta
A sensitive indirect competitive nanobody-based enzyme linked immunosorbent assay (Nb-ELISA) for ochratoxin A (OTA) with high resistance to cereal matrix interference was developed. Nanobodies against OTA (Nb15, Nb28, Nb32, Nb36) were expressed in E....

Cytomegalovirus Immunoglobulin G Avidity Index among Blood Donors in Alexandria, Egypt.

Central European journal of public health
BACKGROUND AND AIM: Transfusion transmitted diseases (TTD) are a major challenge to transfusion services all over the world. Cytomegalovirus (CMV) is considered one of the main viruses associated with blood transfusion. As CMV screening is not includ...

Assessing the association between 25-OH vitamin D levels and ROMA score in a population of obese women.

Journal of biological regulators and homeostatic agents
The “Risk of Malignancy Algorithm” (ROMA) combines the diagnostic power of the CA125 and HE4 markers with menopausal status to predict the risk for developing epithelial ovarian cancer (EOC). The aim of this study was to evaluate the association betw...

Interleukin-6 and interleukin-8 in diagnosing neonatal septicemia.

Journal of biological regulators and homeostatic agents
Neonatal septicemia (NS) is a common cause of death of newborn infants, hence early diagnosis and treatment are of the utmost importance. However, lack of specific clinical symptoms and late detection delay a correct diagnosis. It is therefore of gre...

[Expression of Tim-3 on Peripheral CD56(+) NK Cells and ItsCorrelation with Liver Fibrosis in Patients withAdvanced Schistosomiasis].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases
OBJECTIVE: To explore the expression of T cell immunoglobulin and mucin domain protein 3 (Tim-3) on CD56(+) NK cells in peripheral blood and its correlation with liver fibrosis indicators in patients with advanced schistosomiasis.
