Abstract
Mango (Himsagar cultivar) is a high moisture-bearing seasonal fruit and cultivated in a wide range of the world. Mango pulp is generally preserved by sun drying. In recent days, industries are using hot-air oven, freeze, and microwave drying for mango leather (dried mango pulp in the sheet like texture) processing. Here, all these four drying methods were studied to determine the effect of drying on mango leather processing. RP-HPLC and FTIR were studied for analysis of polyphenol profile and predominant functional groups in raw and processed samples. The phytochemical analysis and medicinal properties (antioxidant, anti-diabetic, and anti-inflammatory activity) of all five mango samples were studied. The bioinformatics approach was studied to evaluate the bioactive potential of the phytochemicals derived from the samples. Freeze-dried mango leather was found to be the highest in DPPH (74.23%) and Superoxide (66.04%) activity, though raw mango pulp was observed with the highest H2O2 activity (73.24%). Gallic acid was the predominant phenolic acid present in all five samples and it was maximum in the case of freeze-dried sample (2.76 ± 0.04 mg/100 g MD). On the other hand, quercetin was the predominant flavonoid, it was found maximum for freeze-dried sample (3.93 ± 0.21 mg/100 g MD).

Abstract
Hardy kiwifruit (Actinidia arguta) is a highly appreciated exotic fruit endowed with outstanding bioactive compounds. The present work proposes to characterize the pulp from A. arguta organic fruits, emphasizing its radicals scavenging capacity and effects on intestinal cells (Caco-2 and HT29-MTX). The physicochemical properties and phenolic profile were also screened. The total phenolic and flavonoid contents (TPC and TFC, respectively) of pulp were 12.21 mg GAE/g on dry weight (DW) and 5.92 mg CE/g DW, respectively. A high antioxidant activity was observed (FRAP: 151.41 μmol FSE/g DW; DPPH: 12.17 mg TE/g DW). Furthermore, the pulp did not induce a toxic effect on Caco-2 and HT29-MTX cells viability up to 1000 μg/mL. Regarding in vitro scavenging capacity, the pulp revealed the highest scavenging power against NO. (IC50 =3.45 μg/mL) and HOCl (IC50 =12.77 μg/mL). These results emphasize the richness of A. arguta fruit pulp to be used in different food products.

Abstract
Aegle marmelos (L.) is a seasonal fruit that contains significant amounts of bioactives like, phenolic acids (gallic acids, 2,3-dihydroxy benzoic acid, chlorogenic acid, p-coumaric acid, vanillic acid), flavonoid (rutin), organic acids (oxalic acid, tartaric acid, malic acid, lactic acid, acetic acid, citric acid, propionic acid, succinic acid, fumaric acid), vitamin C, vitamin B group (thiamine, niacin, pyridoxine, pantothenic acid, biotin, cobalamins, riboflavin), tocopherols (α-tocopherol, β-tocopherol, γ-tocopherol, δ-tocopherol), carotenes (α-carotene, β-carotene, γ-carotene, δ-carotene) and also rich in essential minerals (potassium, calcium, phosphorus, sodium, iron, copper, manganese). This study provides a comprehensive composition analysis (determined using RP-HPLC and Energy Dispersive X-Ray Fluorescence (EDXRF) Spectroscopy). In vitro medicinal activities (antioxidant activity, anti-inflammatory activity, anti-diabetic activity) are quantified for different bael samples. The study also investigates the changes of these bioactive components with freeze, sun, hot air, and microwave drying. The study gives a proper vision to preserve the nutraceutically rich pulp by converting it into fruit leather.

Abstract
This study investigated the specific role played by conserved membrane eukaryotic-like Ser/Thr protein kinases (StkP) during infection, particularly pneumonia, in order to get deep insights about Ser/Thr protein kinases signaling during infection and pathogenesis. The wild type and mutated Ser/Thr protein kinases (Spr1577) strains were tested on different cell lines to understand their virulence based on gentamicin protection assay, gene expression analysis and the expression of various interleukins. Though there was no uptake of bacterial CFU at the beginning, after 24 h it was 50% less for the mutated in comparison to wild-type strain, thus indicating a possible role of Spr1577 gene in the phagosomal survival of S pneumoniae. The complemented, strain-restored bacterial survival to the similar extent alike wild-type strains suggest that the Spr1577 kinase activity is not critical for the intracellular survival of S. pneumoniae within macrophages. Peak expression of spr1577 post infection indicating that the virulent genes seemed persuaded within the macrophages. Higher induction of pro-inflammatory cytokines by the wild type and complemented strains, but not by mutated strain, suggest its role in the induction of macrophages functions. S. pneumoniae and S. pyogenes are closely-related pathogens having 97% similarity in their gene sequences suggesting that the virulence mechanisms greatly varies and remain poorly understood for S. pneumoniae.

Abstract
This study assessed the effect of whey protein substitution with isolated soy protein in protein bar (PB) formulations at 25% (PB2), 50% (PB3), or 75% (PB1) weight/weight on the proximate and mineral composition, sensory, and antidiabetic properties. Sensory evaluation was conducted within diabetic (DB) and non-diabetic (NDB) consumers by preference ranking and acceptance test. The formulations were analysed in terms of moisture, ash, protein, lipid, carbohydrates, fibers and mineral content. The consumers did not distinguish the formulations by preference ranking test. However, the acceptability test showed a rating of 9 most frequent for PB1 (36.30%), followed by PB2 and PB3 (both 34.09%), among DB consumers. The PB1 and PB3 showed higher content of total, soluble and insoluble fibers and, PB 2 presented higher carbohydrate content. Potassium, sodium and calcium showed the highest mineral content in the formulations. PB3 was assessed for glycaemic and lipidemic control in diabetics and non-diabetics female Wistar rats, for this 20% of PB was added in the ration consumed ad libitum, besides, the rats received 100 mg/kg b. w. by gavage daily. The treatment did not reduce significantly fasting glucose, lipid profile, or peripheral glucose disposal in DB or NDB rats. However, it significantly improved insulin tolerance test values in diabetic rats. The results suggest that the formulations showed good acceptance and potentially ameliorate insulin resistance both in control group and in animal model of type II diabetes.

Abstract
Insulin resistance is an abnormal physiological state that occurs when insulin from pancreatic β-cells is unable to trigger a signal transduction pathway in target organs such as the liver, muscles and adipose tissues. The loss of insulin sensitivity is generally associated with persistent hyperglycemia (diabetes), hyperinsulinemia, fatty acids and/or lipid dysregulation which are often prevalent under obesity conditions. Hence, insulin sensitizers are one class of drugs currently employed to treat diabetes and associated metabolic disorders. A number of natural products that act through multiple mechanisms have also been identified to enhance insulin sensitivity in target organs. One group of such compounds that gained interest in recent years are the dietary anthocyanins. Data from their in vitro, in vivo and clinical studies are scrutinized in this communication to show their potential health benefit through ameliorating insulin resistance. Specific mechanism of action ranging from targeting specific signal transduction receptors/enzymes to the general antioxidant and anti-inflammatory mechanisms of insulin resistance are presented.

Abstract
Phoenix dactylifera L. plays an important role in social, economic, and ecological Tunisian sectors. Some date palms produce parthenocarpic fruit named Sish. The aqueous ethanolic extract from P. dactylifera parthenocarpic dates demonstrated a potent inhibition of the enzymes related to type II diabetes. In this work, extraction optimization of amylase inhibitors was carried out using Box-Behnken Design. Bioactivity-guided fractionation of the 70% aqueous ethanol extract was performed to identify the active compounds. The physicochemical results by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis showed the presence of 13 phenolic compounds. The in vitro study showed that the extract exhibited a more specific inhibitor of α-glucosidase than α-amylase with an IC50 value of 0.6 and 2.5mg/mL, respectively. The in vivo study of this extract effect on the postprandial hyperglycemia activity showed a decrease in plasma glucose levels after 30min stronger than the Acarbose effect. These results confirmed the anti-postprandial hyperglycemia activity of the aqueous ethanolic extract from P. dactylifera parthenocarpic dates, which could lend support for its pharmaceutical use.

Abstract
Gamma irradiation (0.5-2.5 kGy) in combination with low temperature (4-15 °C) storage was attempted to increase shelf life of ready-to-cook shredded cabbage wrapped in cling films. A maximum extension in shelf life of 8 days, while retaining the microbial and sensory quality, was obtained with an irradiation dose of 2 kGy and storage at 10 °C. Gamma irradiation also inhibited browning of shredded cabbage at their cut edges resulting in enhanced visual appeal. An increase in total antioxidant activity was observed with respect to DPPH and hydroxyl radical scavenging ability while the nitric oxide radical scavenging activity and ferric reducing property remained unaffected with irradiation. Total phenolic, flavonoid and vitamin C content remained unchanged due to irradiation. No significant migration of additives from cling films into stimulant water was observed up to a radiation dose of 2 kGy thus demonstrating the feasibility of such films for above applications.

Abstract
Optimum water extraction conditions for phenolics of pomegranate peels were investigated by fractional factorial and face-centered central composite designs. Five potential factors were selected for the fractional factorial design: extraction technique, extraction temperature, extraction time, particle size and solvent to solid ratio. After eliminating statistically unimportant factors, a face-centered central composite design was set up with two controllable factors and with two responses: total phenolics and α-glucosidase inhibition activity. Optimum conditions were found as 100 °C for extraction temperature and 1 min for extraction time. There were no statistically significant differences (p > 0.05) between water extracts at optimized conditions and classical methanol extracts. Total phenolic content by HPLC was192.0 mg/g of pomegranate peels on dry matter basis. Phenolics of pomegranate peels showed α-glucosidase inhibition activity with an IC50 (concentration of phenolics required to inhibit 50 % of the enzyme activity) value of 5.56 ± 2.23 μg/ml. Pomegranate peel phenolics with its antioxidant and α-glucosidase inhibition properties might be a suitable ingredient for functional food applications.
