Assessment of inhibitory activity of hydrolyzed camel whey protein concentrate and its peptides against some fungi Paper ID: AJFSN-08-09-2022-200
Abstract : The objective of this study was to investigate the antifungal activity of different concentrations (5, 10 and 20 mg/ml) of camel whey protein concentrate (WPC) and its hydrolysates against Candida albicans, Asperigillus fumigatus, Asperigillus niger and Asperigillus flavusThen, the strongest antifungal hydrolysate was further fractionated on fast performance liquid chromatography (FPLC) to separate the potent peptide subfractions at concentration of 1.45 mg/ml. The results revealed that the pepsin-trypsin (P-T) hydrolysate (20 mg/ml) showed the strongest antifungal activity, followed by 20 mg/ml of both unhydrolyzed WPC and pepsin (P) hydrolysate against C.albicans, A.fumigatus, A.niger and A.flavus, respectively.However all tested conentrations of trypsin (T) hydrolysate had the lowest activity against all strains.Thus, the potent P-T hydrolysate was subjected to further fractionation and the potent lower molecular weight peptide subfractions (SFs) (< 20kDa) were SF18 against A.niger, SF14 against A.fumigatus and A.flavus, repectively and SF21 against C.albicans.Camel´s WPC, its hydrolysates and the potent peptide subfractions (SF18 and SF14) had more hydrophobic amino acids, however SF21 had more hydrophilic amino acids. Consequently, it′s concluded that P-T camel´s WPC hydrolysate can be applied as a natural effective antifungal agent.

Abstract : To study the correlation between the expression of tumor microenvironment receptors and molecular biological subtypes of breast cancer, as well as their effect on prognosis. To improve the diagnosis and treatment of breast cancer by studying the tumor microenvironment, its impact on the course and prognosis, we analyzed a group of 457 breast cancer patients. PD-1, PD-L1, EGFR and CK 5/6 in luminal tumors had lower values than in triple-negative forms of breast cancer. In luminal type A - PD-1=30%, PD-L 1 - 17.7%, EGFR - 5.9%, and CK 5/6-3.3%, whereas in triple-negative cancers, these indicators were 61.7%, 39.8%, and 53.4%, respectively. Data analysis showed that there is a strong correlation between the expression of the above markers and molecular biological subtypes of breast cancer.

Nutritional quality of Solanum aethiopicum L. Shum berry as affected by agroecological zones of production Paper ID: AJFSN-06-03-2022-196
Abstract : Solanum aethiopicum L. Shum (SAS) berries are consumed either raw or as in the form of a tea. This work was performed to study the chemical composition and microbial load of SAS berry harvested from five agroecological zones in Cameroon. The results showed that, berries freshly harvested from all the five agroecological zones were highly contaminated by microorganisms. Berries from the highlands and bimodal rainfall forest zones had a higher rate of contamination, while they were less contaminated in the sudano-sahelian zone. The berries were cleaned with sodium hypochlorite eliminating them from pathogenic microorganisms. The agroecological zones influenced the chemical composition of the SAS berries (P < 0.05), with exception of proteins and lipids (P > 0.05). These berries were more concentrated in the Sudano-sahelian zone and more hydrated in the monomodal rainfall forest zone. However, carbohydrates were the most abundant macronutrient irrespective of the place of production, bitter taste of berries is probably determined by their phytonutrients. Mineral salts such as calcium, magnesium, potassium varied following the agroecological zones, as well as trace-elements like zinc and manganese (P < 0.05), Compared to the iron which reminded unchanged irrespective of the place of production (P > 0.05). These results suggested that the chemical composition and microbial load of SAS depended on the agroecological zones, while confirming their richness in important nutrients.

Effect of fiber type and content on mechanical properties of non-proprietary UHPC concrete Paper ID: BJCAE-01-03-2022-195
Abstract : The purpose of this study was to investigate the effect of fiber type and content on the mechanical properties of non-proprietary, cost-effective ultra-high-performance concrete (UHPC) mixtures using locally produced material in the state of Florida with crushed limestone fine aggregate. Ultra-fine recovery (UFR) material was used for the first time to improve the particle packing and density of the non-proprietary UHPC mixtures. The UHPC mixes were developed using particle packing analysis and then modified through small trial batches. Qualified mix designs were further evaluated through several different experimental tests, including bulk resistivity. Results showed that using steel fibers with 0.2 mm diameter and 13mm length led to better performance compared to longer metallic fibers and nonmetallic fibers, and less clumping and segregation issues were observed on samples containing these fibers (0.2 mm and 13 mm length). In conclusion, non-proprietary UHPC mix designs containing 2% steel fibers made by locally produced material in Florida, can obtain comparable performance to commercial versions of UHPC mixtures.

Antibacterial property of commonly used spices in Abuja, Nigeria Paper ID: AJFSN-08-08-2021-190
Abstract : Spices are additives to improve the flavor, taste, and colour of food. Spices are also known to extend shelf life by inhibiting growth or decreasing food borne pathogens. The study is aimed to evaluate seven spices for antibacterial properties on some bacteria. The local and botanic names of the seven spices are Ehuru (Monodora myristica), Uziza (Piper guineese), Turmeric (Curcuma longa), Garlic (Allium sativum), Ginger (Zingiber officinale), Cayenne pepper (Capsicum annum), cinnamon (Cinnamonum cassie) were purchased in the market in Abuja, Nigeria and identified in Herbarium Unit of National Institute for Pharmaceutical Research and Development, these spices were dried and pulverized into powder. These powders were extracted with 70% methanol into crude extracts. The crude extracts were screened for antibacterial property against Salmonella typhi, Escherichia coli, Staph. aureus and Bacillus subtilis at varied concentration of 80,40, 20 and 10 mg/mL using the agar. Curcuma longa and Piper guineese inhibited the growth of test bacteria at the concentration of 10 mg/mL while Cinnamonum cassie and Capsicum annuum inhibited the growth of three of the test bacteria. Zingiber officnale crude extract was found to be resistance against to E. coli and Salmonella typhi, while Allium sativum extract was also exhibit resistance to Sal. typhiand E. coli growth. Monodora myristica crude extract was found to have not inhibitory potential on the test bacteria. The concentration of 10 mg/mL
