RESUMO
Colour plays an important role in consumer’s perception and acceptability of the food product. Therefore, colour measurement and analysis is one of the most important quality attributes to optimize the quality and value of food. Different blends of gluten-free maize flour, finger millet (Ragi) flour and quinova flour were used as raw materials for the development of pasta. Hunter Lab Colorimeter was used for measuring the surface color of the uncooked pasta samples. High quality pasta (either fresh or dried) is normally yellow in colour and the degree of yellowness can be calculated by using b* and L* values. Quality of pasta developed by different blend ratio of maize, ragi and quinova flours with different levels of CMC, Karaya Gum and dried at different drying temperature and air flow rates were evaluated in terms of L* values (lightness), b* values (yellowness) and Yellowness Index (YI). Results of colour analysis of gluten-free pasta samples indicated a significant effect of flours on L*, b* and YI while drying air temperature have a significant effect on b* values. Pasta samples prepared following optimized formulation 50:25:25 (Maize flour: Ragi, flour: Quinova flour) blend ratio, 5g CMC per 100g of blend ratio, 2.5g Karaya Gum per 100g of blend ratio, 60 0C drying air temperature and 0.78 m/sec. air flow rate provided optimum L*, b* and YI values with overall desirability of 0.545.
RESUMO
Objective: to study the clinico-epidemiological profile of sexually transmitted infections [STIs] among the children
Methods: it as a cross-sectional hospital-based study. Children [up to 13 years] with suspected STI were included in this study. Diagnosis of STI was done on the basis of detailed history, clinical examination and relevant laboratory investigations
Results: a total of 8,421 STI patients were seen during this period, out of which 57 were children. The commonest STI was seen in the age group of 10-13 years [71.9%]. The predominant STIs observed among these children were condyloma acuminata [genital warts] [40.3%], syphilis [14.9%], gonorrhea [13.4%], vaginal candidiasis [13.4%], herpes progenitalis [10.5%], molluscum contagiosum [6.0%] and HIV [1.5%]. In majority of cases culprits were family members
Conclusion: genital wart was the most common STI in children. Vaccination to prevent genital warts should be considered seriously
RESUMO
Objective/background: There is an urgent need for a more effective vaccine against Mycobacterium tuberculosis [Mtb]. Although CD4+ T cells play a central role in host immunity to Mtb, recent evidence suggests a critical role of CD8+ T cells in combating Mtb. In the present study, we have predicted HLA antigen class I binding peptides of DosR operon using an in-silico approach. This method is useful as an initial computational filtration of probable epitopes based on their binding ability and antigenicity
Methods: CD8+ epitopes were predicted by software NetMHC 3.4 and BIMAS. Self-peptides were found and excluded by indigenously developed Perl script. Antigenicity of promiscuous peptides was predicted using a Vaxijen server. The top Vaxijen scoring antigenic peptides were docked to globally relevant HLA allele using CABS dock and Hex program
Results: A total of 1436 overlapping nonamer peptides were generated which gave 46 promiscuous epitopes, 25 were predicted to be antigenic. Rv2627 epitope "SAFRPPLV" which gave the highest Vaxijen score of 1.9157 and showed binding to all the three HLA loci. The top Vaxijen scoring antigenic peptides were docked and had significant interactions with residues of the HLA class I molecule indicating them to be good cytotoxic T lymphocyte epitopes
Conclusion: Our study has generated several promiscuous antigenic peptides capable of binding to major histocompatibility complex class I with high affinity. These epitopes can become part of a postexposure multivalent subunit vaccine upon experimental validation
