Starch films containing a chemodosimeter probe based on a quinolinium merocyanine dye were successfully prepared and studied. Through the selective nucleophilic addition reaction between cyanide anions and the dye chromophore the film can selectively detect sub-micromolar quantities of cyanide ion by a distinct color change. © 2012 Elsevier Ltd.

Moroccan population has known a growing demographic trend. However, beyond the global tendency, reproductive health remains characterised by inequalities and disparities between urban and rural, rich and poor, developed and deprived regions. In this study, we relied mainly on data and statistics provided by the last five censuses, the four Demographic Health Surveys, Multiple Indicator Cluster Surveys, reports of international bodies and publications dealing mainly with health and development in the Arab World. During the last decades, fertility declined due to different parameters. Infant mortality decreased and should reach the corresponding Millennium Development Goal whereas maternal mortality has stayed nearly constant. The achievements accomplished in reproductive health remain insufficient. Family planning and contraception policies need to reach more women; and antenatal and postnatal care should be enhanced especially towards poor women living in rural areas and deprived regions.

Blood platelets are directly involved in both haemostatic and pathologic thrombotic processes, through their adhesion, secretion and aggregation. In this study, we investigated the effect of genins (aglycone flavonoids without sugar group) isolated from parsley (Petroselinum crispum) leaves in vitro on human platelet aggregation and adhesion to a collagen-coated surface under physiologic flow conditions. Materials and Methods: The aggregation and adhesion studies were monitored after pre-incubation of platelets with genins. Genins inhibited dose dependently aggregation induced by thrombin, ADP and collagen. The strongest effect was observed in collagen induced aggregation (IC50 = 0.08 ± 0.01 mg/ml). The HPLC identification of genins compounds revealed the presence of keampferol, apigenin and other not identified compounds. The aggregation tests showed that these compounds have anti-aggregating activity. In addition, adhesion of human platelets to collagen was greatly decreased (over 75 %) by genins (0.3 mg/ml). While the mechanism by which genins act is unclear, we suggest that these compounds may interfere with a multiple target step in the haemostasis process. These results show that genins isolated from parsley has a potent antiplatelet activity. It may be an important source of beneficial antiplatelet compounds that decrease thrombosis and cardiovascular diseases.

Numerous studies have shown that diabetic nephropathy (DNP) is associated with an elevated risk of progression toward end-stage renal disease (ESRD) as well as increased cardiovascular mortality. The majority of these studies are from the developed countries. The factors leading to the progression of DNP may not be quite the same in the developing countries. The aim of this study was to evaluate the risk factors of progression toward ESRD and mortality among type-1 diabetes (T1D) patients with DNP in a developing country. This prospective study was conducted enrolling 72 patients with T1D in September 2006, including T1D patients with DNP defined as microalbuminuria, proteinuria, and/or renal failure, and following them up for five years. The mean age was 29.5±7.5 years with a mean duration of diabetes of 17 (11-20) years. At the time of enrollment, 43.1% had arterial hypertension, 69.4% had proliferative retinopathy, 44.4 had clinical neuropathy, 25% lived in rural areas, and 51.4% had macroalbuminuria. Progression toward ESRD was observed in 34.7% of cases. In multivariate analysis, diastolic blood pressure (P = 0.006) and blood hemoglobin (P = 0.003) were identified as the risk factors associated with ESRD. Death occurred in 18.3% of cases, including 92.3% on hemodialysis with a median hemodialysis duration of six (1-60) months. In multivariate analysis, the ESRD was identified as risk factor for death (P <0.001). DNP due to T1D remains a disease involving a heavy burden of morbi-mortality and is difficult to manage in a developing country because of the low socioeconomic level of patients and the lack of reliable epidemiological data.

The goal of this study was to examine the effect of Virgin Argan Oil (VAO) obtained from the fruit of Argania spinosa in a model of type 2 diabetes and hypertensive rats. Neonatal diabetes was induced by a single i.p. injection of streptozotocin (90 mg/kg) 2 days after birth. To induce NO-deficient hypertension, the adult diabetic animals were treated with l-nitroarginine methylester (l-NAME) (30 mg/kg/day) given orally for 21 days. Following treatment with VAO (21 days), the hyperglycemia decreased to 1.3 ± 0.07 g/l compared with 1.92 ± 0.09 g/l (p < 0.01) in the untreated diabetic-hypertensive rats. The simultaneous administration of VAO with l-NAME prevented the increase in blood pressure during the 3 weeks of treatment. Blood pressure remained constant at 131 ± 1 mm Hg after 21 days - vs 157 ± 0.64 mm Hg in untreated animals (p < 0.001). The treatment with VAO to diabetic-hypertensive rats caused a significant increase of hepatic glycogen levels (13.3 ± 1.8 vs 6.34 ± 0.75 mg/g tissue in untreated diabetic-hypertensive control group; p < 0.01). In conclusion, the overall findings indicate that VAO possesses antidiabetic and antihypertensive activity in n-stz/l-NAME rats. This effect may be related to its high content of tocopherols, phenolic compounds, and unsaturated fatty acids.
