Nine accessions of Bambara groundnut (Vigna subterranea (L.) Verdc.,syn. Voandzeia subterranea (L.) Thouars ex DC.)  obtained from National Centre for Genetic Resources and Biotechnology (NACGRAB), Ibadan, Oyo state, were assessed for their genetic and phylogenetic relatedness through electrophoretic analysis of the seed proteins. 0.2g of the seeds were weighed and macerated with mortar and pestle in 0.2M phosphate buffer containing 0.133M of acid (NaH2PO4) and 0.067 of base (Na2HPO4) at pH 6.5. Protein characterization with standard marker revealed that the seeds of the nine accessions contained proteins (B.S.A, Oval Albumin, Pepsinogen, Trypsinogen and Lysozyme) with molecular weights ranging from 66kda and above, 45 – 65 kDa, 44 – 33 kda, 32-24 kDa and 23-14 kDa, respectively. The student T-test revealed that accessions B, C, E, F, H and I have molecular weights not significantly different from one another (P<0.05) while samples A, D and G showed significantly different values (P>0.05). All the accessions had at least two proteins and two major bands in common. The study revealed intra-specific similarities and genetic diversity in protein contents among the nine accessions of Bambara groundnut (Vigna subterraranea (L.) Verdc.syn

Background: Pancreatic carcinoma is a disease with high modality and has a high incidence of recurrence after surgical resection. The prognosis depends on early diagnosis and treatment. Numerous international studies have reported use of CA 19-9 in diagnosis of pancreatic cancer. We planned this study to validate role of CA 19-9 in our local population. The objective of this study is to correlate raised serum CA 19-9 levels in patients with pancreatic tumours to distinguish between benign and malignant pancreatic disease. Subjects and methods: The present study is a validation study. Thirty-five patients with diagnosis of pancreatic tumor on radiological imaging were included after their informed consent. Data collection forms were filled, blood samples were taken and serum CA 19-9 was estimated by ELISA in Biochemistry department, SIMS. Histopathology samples were collected at time of surgical resection, sent to pathology departments of respective hospitals and histopathological reports collected. All data was collected and analysed by using descriptive method. The study was conducted in Biochemistry department of PGMI and SIMS, Lahore from May 2015 till June 2016. Results: Out of 35 patients, nineteen (54.3%) were female and sixteen (45.7%) were male. Thirty [85.7%] patients were between third to seventh decades of their life. The mean age range around 47.28. Thirty-four patients had malignant tumor and 1 benign on histopathology. CA 19-9 was raised (>37 U/ml) in 33 out of 34 patients with malignant pathology. The patient with benign pathology had CA 19-9 level <37U/ml (the cut off value). Head of pancreas was the commonest site in 32 patients (65%) for tumour occurrence. Total 28 (82%) patients had adenocarcinoma as the histological type of pancreatic tumour. Cholangiocarcinoma in Periampullary region of pancreas was second in frequency, 4 patients (12%). CA 19-9 shows sensitivity of 97% and specificity of 100% to diagnose carcinoma of pancreas in patients with pancreatic tumour. CA 19-9 has 100% positive predictive value to diagnose benign tumour and 50% negative predictive value to diagnose malignant tumours. Conclusion: Raised levels of CA 19-9 has an important role in diagnosis of patients with pancreatic tumour to differentiate between benign and malignant pathology.

Adzuki seed β-vignin, a vicilin-like globulin, has proven to exert various health-promoting biological activities, notably in cardiovascular health. A simple scalable enrichment procedure of this protein for further nutritional and functional studies is crucial. In this study, a simplified chromatography-independent protein fractionation procedure has been optimized and described. The electrophoretic analysis showed a high degree of homogeneity of β-vignin isolate. Furthermore, the molecular features of the purified protein were investigated. The adzuki bean β-vignin was found to have a native size of 146 kDa, and the molecular weight determined was consistent with a trimeric structure. These were identified in two main polypeptide chains (masses of 56–54 kDa) that are glycosylated polypeptides with metal binding capacity, and one minor polypeptide chain with a mass 37 kDa, wherein these features are absent. The in vitro analysis showed a high degree of digestibility of the protein (92%) and potential anti-inflammatory capacity. The results lay the basis not only for further investigation of the health-promoting properties of the adzuki bean β-vignin protein, but also for a possible application as nutraceutical molecule.
