Evaluation of the Riverine Vegetation of Wadi Tafna in the Tlemcen region (Western Algeria)

The vegetal landscape of riverine forest bordering streams of course, has a character linked to the high volatility of the intermittence of the latter. The watercourse temporary (wadis) are characterized by a vegetation and flora of Mediterranean type, (Tamarix, Nerium, Vitex, Phoenix...) in contrast to the permanent water courses at the level of the vegetation of leafy bed major European type, based mainly, poplar, ash or alder. In Western Algeria, the riverine forest vegetation is complex and fragile environments to several utilities. Latter by its diversity and these developed root systems will thus limit erosion of the banks and provide a stable structure to the formation. To identify and quantify the riverine forest on the Mediterranean coast in the South, especially in Western Algeria, we conducted surveys on land with an area of 100 m2 for each record, and then each species was conducted of two indices (abundance – dominance and sociability. The factorial analysis of correspondences has carried out us to classify these plant species according to the degree of salinity of the Wadi, the substrate and the slope. The riverine vegetation of wadi Tafna has been classified as follows: The so-called purely riverine forest vegetation is which are directly linked to the Wadi (in contact with the water and who are): Tamarix africana; Nerium oleander; Fragmites communis; Chenopodium album; Rumex bucephalophorus; etc. Vegetation low riverine forest is usually trained pre-forestieres species on siliceous substrate and are: Crateagus monogyna; Halimium halimifolium; Withania frutescens; Atriplex halimus; Acacia sp; Zygophyllum sp; Bryonia dioica; Calycotome intermedia; Suaeda sp. In conclusion, the inadequacy of our knowledge of the biology and ecology of vegetation riverine forest of our region requires multiscale study and multidisciplinary in order to better understand the structure and operation of all hydro-system. These phyto-sociological and phyto-dynamic data lead to classify these plants according to ecological factors of their site and understand its evolution and diversity through the study area.

Expression Signature of MicroRNA-155 and its Association with Response to Treatment within Different Subtypes of B-Cell Malignancies

Objectives: Emerging evidence suggests that microRNAs could serve as non-invasive biomarkers for cancer patients. However, they are mostly not fully investigated as biomarkers in the classification, progression and prognosis of different cancers. Our study was designed to explore the microRNA-155 (miR-155) expression levels in peripheral blood mononuclear cells (PBMCs) in patients with various subtypes of B-cell malignancies. Also, we aimed to correlate between miR-155 expression levels and the diverse clinico-pathologic features as well as the prognostic fate of these patients after treatment completion. Subjects and methods: Using whole blood samples from 53 patients with B-cell malignancies and 15 apparently healthy subjects, miR-155 was extracted and profiled by quantitative real-time PCR (RT-qPCR). The B-cell malignancies patients were including 22 diffuse large B-cell lymphoma (DLBCL), 15 chronic lymphocytic leukemia (CLL), 9 follicular lymphoma patients (FL) and 7 subjects with burkitt′s lymphoma (BL). The samples were withdrawn before starting chemotherapy in addition to after completing their therapeutic courses by 6 months. Subsequently, the patients were further sub-grouped into those with partial remission, complete remission, resistant disease and relapse. Results: We found that miR-155 expression levels differentiate lymphoma entities from normal subjects (p ≤ 0.001) and its expression fold changes distinguish B-cell lymphoma subtypes from each other’s (p<0.05). In addition, miR-155 was significantly correlated with age and LDH levels. The receiver operating curve (ROC) was employed to identify the diagnostic outcomes of miR-155 in discriminating B-cell malignancies entities from each other’s (AUC=0.957 for DLBCL vs. CLL+FL and AUC=1.000 for CLL vs. FL). Otherwise, when BL was versus healthy controls the AUC was equal to 0.552. As well, we demonstrated an association between elevated miR-155 expression levels and poor response to treatment with increased cases of relapse, partial remission or resistance to treatment. Conclusions: This study suggests that miR-155 has an expression profile that differs according to B-cell malignancies subtype. Besides, miR-155 expression levels may modulate the patient’s response to treatment. These results support a role for miR-155 to provide helpful diagnostic/prognostic information in B-cell malignancies and may highlight novel pathways to be targeted for therapeutics in the future.

Antioxidant and Postprandial Glucose-lowering Potential of the Hydroethanolic Extract of Nypa fruticans Seed Mesocarp

Postprandial hyperglycemia and oxidative stress are implicated in the pathophysiology of type 2 diabetes. An alternative treatment should target both conditions. The present study aimed to evaluate the antioxidant and postprandial glucose-lowering potential of a polyphenolic rich extract of Nypa fruticans nuts. Hydroethanolic extract (HEE) was prepared; polyphenol and fl avonoid content was determined. In vitro antioxidant activity was done through molybdenum (VI) reduction and ABTS and DPPH radical-scavenging capacities. The glucose-lowering potential of the extract was evaluated through in vitro glucose-binding capacity, the regulatory ability of the extract on the pancreas of normal Wistar rats (oral glucose tolerance test), and digestion of carbohydrates (starch and sucrose) by normal Wistar rats. Starch (1 g/kg of the body weight (BW) and sucrose (2 g/kg BW) solution were used as substrates for alpha amylase and invertase inhibition test, respectively. Acarbose (3 mg/kg BW) was used as the reference. Polyphenolic-rich extract (400 mg/kg BW) was administered to treated rats. Results showed that HEE of N. fruticans nuts has antioxidant activity through the scavenging of ABTS (EC50 of 1.75 mg/mL) and DPPH (2.96 mg/mL) radicals and the reduction of Mo (VI). The extract signifi cantly reduced glucose concentrations at t 30 compared to glibenclamide, but glibenclamide maintained lower glycemia than the extract thereafter to the end of the study. From the administration of sucrose, the extract maintained lower plasma glucose levels compared to acarbose throughout the study. However, no inhibition was observed in glycemia following starch administration in HEE-treated group as glycemia remained higher compared to the acarbose group throughout the study. Thus, N. fruticans seed mesocarp is a rich source of dietary polyphenols with a strong antioxidant capacity. Its HEE has glucose-lowering potential and possible inhibitory action on the last phase of carbohydrate digestion.
