Abstract:

The development of resistance to currently known conventional anti-typhoid drugs has necessitated search into cheap, more potent and less toxic anti-typhoid drugs of plant origin. Therefore, this study investigated the anti-typhoid activity of fractions of A. indica in Salmonella typhi infected rats. Leaves of A. indica were extracted in methanol and fractionated into n-hexane, chloroform, ethyl-acetate and aqueous fractions. The anti-salmonella potentials of fractions of A. indica were assessed via in-vitro inhibition of S. typhi using agar well diffusion, Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and biofilm assays. The biochemical and haematological parameters were determined by spectrophotometric methods. The histological analysis was performed using Haematoxylin and Eosin staining methods. Data analysis was performed by one -way ANOVA. Results of this study showed that S. typhi was sensitive to aqueous and chloroform fractions of A. indica and the fractions showed biofilm inhibition at concentrations of 12.50, 1.562 and 0.39 mg/mL. In the in-vivo study, the extract and chloroform fraction had significant (p<0.05) effects on the number of viable S. typhi recovered from the blood and stopped salmonellosis after 6 days of treatment of rats at 500 mg/kg b.w. Treatments of infected rats with chloroform and aqueous fractions of A. indica normalized the haematological parameters in the animals. Similarly, treatment with fractions of the plants sustained a normal antioxidant status when compared with the normal control group. Chloroform and ethyl-acetate fractions of A. indica reversed the liver and intestinal degeneration induced by S. typhi infection in rats. The present investigation indicated that the aqueous and chloroform fractions of A. indica showed the potential to provide an effective treatment for salmonellosis, including typhoid fever. The results of the study may justify the ethno-medicinal use of the extract in traditional medicine for the treatment of typhoid and salmonella infections

Abstract:

Pregnant women have always used phytotherapy to treat some ailments during their pregnancy. An Ethnopharmaological approach was used in Tlemcen city (extreme western area of Algeria) to know the profile of the pregnant women who use the medicinal plants to treat their health problems, and to identify and repertory these plants. The survey was conducted among 55 pregnant women interviewed in the university hospital of Tlemcen, using a questionnaire. SPSS was used for statistical analysis.

A total of 46 medicinal plants were reported, belonging to 23 different families.  The majority (34%) of the pregnant women who use plants were young (32,72%) with a university level. Whether they live in or around the city, there is almost no difference in use (27,27% , 29,09 %). The results provide a very valuable source of information about the medicinal flora of the region. It could be a database for other research in the futur to explore the composition of these plants wich are effective against different pregnancy ailments.

Abstract:

The effect of applying Ulva lactuca aqueous extract (ULAE) with different concentrations on the growth of maize seedlings was studied. The extract was applied as foliar spray and in other experiment was incorporated in the growth nutrient solution. Growth parameters, mineral nutrients, photosynthetic pigments, protein profile, and phospho enolpyruvate (PEPCase) activity were monitored. Presoaking maize grains in different ULAE was an effective technique to obtain better growth. Seedlings sprayed with 0.5% or 1% ULAE showed a significant increase in growth and biochemical parameters. Higher concentration (5%) showed inhibitory effect. There were variable peptides with different low molecular weights that were synthesized in all treatments except for the control one (100% H). For example, in seedlings sprayed with 5% ULAE proteins as 27, 24, 23, 12 and 10 KDa were synthesized. Similar low molecular weight proteins were synthesized in all other treatments but with different band intensities. Furthermore, treatments with ULAE as a foliar spray or supplemented in the growth medium differentially affected protein expression in Z. mays seedlings. New proteins were expressed in the treated seedlings which could be due to the action of components in the extract that are bioactive for growth. PEP carboxylase activity in Z. mays seedlings grown in different combinations of Hoagland’s solution and ULAE was higher than that of seedlings sprayed with ULAE alone. There was a gradual decrease in enzyme activity in response to increasing ULAE applied as foliar spray and the least activity was recorded in seedlings sprayed with 5% ULAE.

Abstract:

A glycoprotein alpha amylase inhibitor (α-AI), molecular weight of 8.3 kDa, was isolated and purified from seeds of Withania somnifera (WSAI), an important indigenous medicinal plant. It is thermostable and non-competitive type inhibitor of fungal amylase. Mass spectrometric analysis revealed that it shares 59% sequence similarity with Wrightide II type α-AI from W. religiosa. When the adults of T. castaneum were fed with WSAI (1.6 mg/g), decrease in consumption, growth and efficiency of conversion of ingested food were evident along with over 4-fold increase in feeding deterrence index and decrease in longevity. In another approach, the treatment of WSAI to potato slices at 200 ppm concentration for 30 min was found to reduce the browning (60%), residual amylase and polyphenol oxidase activities (~40%) and reduction in reducing sugar level by 25% over control. In conclusion, i) WSAI has good potential in mitigating overall growth and development of T. castaneum and thus make it a potential candidate for its management, individually or in combination with other insect controlling biological molecules and ii) WSAI treatment results in reduction in browning and generation of acrylamide in potato during processing. Thus, it offers a heathier (better nutritional value) and economical (significant improvement in dry weight post frying) alternative method without compromising the overall sensory quality of the finished product.

Abstract:

Extra-virgin olive oil (EVOO) polyphenols contribute to Mediterranean diet health-promoting properties. One of the most abundant secoiridoid present in EVOO, Oleacein (OA), demonstrated anticancer activity against several tumors. Nevertheless, its role against melanoma has not still investigated. This study aimed at determining in vitro the anti-melanoma activity of OA and the relative mechanism of action. OA induced cell growth inhibition in 501Mel melanoma cells with an IC50 in the low micromolar range of concentrations. Moreover, an OA concentration approximating the IC50 induced G1/S phase arrest, DNA fragmentation, and down-regulation of genes encoding anti-apoptotic (BCL2 and MCL1) and pro-proliferative (c-KIT, K-RAS, PIK3R3, mTOR) proteins, while increased transcription levels of the pro-apoptotic protein BAX. Concordantly, OA increased the levels of miR-193a-3p (targeting MCL1, c-KIT and K-RAS), miR-193a-5p (targeting PIK3R3 and mTOR), miR-34a-5p (targeting BCL2 and c-KIT) and miR-16-5p (targeting BCL2, MCL1, K-RAS and mTOR), while decreased miR-214-3p (targeting BAX). These modulatory effects might contribute to the inhibition of 501Mel melanoma cell growth observed after treatment with an olive leaves- derived formulation rich in OA, with potential application against in situ cutaneous melanoma. Altogether, these results demonstrate the ability of OA to contrast the proliferation of cutaneous melanoma cells through the transcriptional modulation of relevant genes and microRNAs, confirming the anticancer potential of EVOO and suggesting OA as a chemopreventive agent for cancer disease therapy.
