Objectives: To estimate vitamin D levels in children with type 1 diabetes, and to evaluate its role the pathogenesis progress of disease.Method: The cross-sectional study was conducted at Paediatric Department Kafrelsheikh University Hospital, Egypt, from November 2019 August 2021, comprised either gender aged 3-18 years who were inpatients or visiting paediatric outpatient clinic. subjects enr...

  Introduction: Ubiquicidin 29-41 (UBI) is a fragment of the cationic antimicrobial peptide that is present in various species including humans. The purpose of this study was to investigate radiochemical and biological characteristics of [6-hydrazinopyridine-3-carboxylic acid (HYNIC)]-UBI 29-41 designed for the labeling with 99mTc using tricine as coligand....

introduction: glycoprotein b (gb) is the major antigen for induction of humoral responses against human cytomegalovirus (hcmv) making it an attractive candidate for immune prophylaxis. in the present study, the humoral immune response of balb/c mice to a truncated hcmv gb protein fused with gfp was evaluated. methods: the truncated gb coding sequence was synthesized and cloned in pegfpn1 eukary...

objective(s):tumor-associated antigen (taa) subunit-based vaccines constitute promising tools for anticancer immunotherapy. however, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.the aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic her2/neu derived pept...

BALB/c, (BALB/c x B10.A)F1 and (BALB/c x B10)F1 hybrid mice were immunized with C-peptide of human proinsulin. The (BALB/c x B10.A)F1 hybrids were the best responders and yielded 3 hybridomas secreting specific monoclonal antibodies. One of them, C-PEP-01, bound the C-peptide with high affinity (Kas = 1.1 x 10(9) l/mol), cross-reacted fully with human proinsulin but not with insulin, glucagon o...

conclusions it seems that rj does not appear to have significant immediate effects on glycemic factors in patients with type 2 diabetes. however, further studies with larger sample sizes and different doses of rj are needed to achieve more precise results. background type 2 diabetes is the fourth major public health problem worldwide. royal jelly (rj) insulin-like activity and blood glucose mod...

C-peptide, a cleavage product of the proinsulin molecule, has long been regarded as biologically inert, serving merely as a surrogate marker for insulin release. Recent findings demonstrate both a physiological and protective role of C-peptide when administered to individuals with type I diabetes. Data indicate that C-peptide appears to bind in nanomolar concentrations to a cell surface recepto...

BACKGROUND C-peptide is a marker of insulin secretion in diabetic patients. We assessed within- and between-laboratory imprecision of C-peptide assays and determined whether serum calibrators with values assigned by mass spectrometry could be used to harmonize C-peptide results. METHODS We sent 40 different serum samples to 15 laboratories, which used 9 different routine C-peptide assay metho...
