Notre objectif est de présenter une synthèse sur l’étude de la stabilité du rendement de dix variétés de blé dur expérimentées pendant quatre ans (2009-2013) dans la région semi-aride de Sétif. Nous utilisons au cours de cette étude trois indices de stabilité paramétriques et non paramétriques pour évaluer les performances des dix génotypes testés. L’étude des indices paramétrique de stabilité, notamment l'écovalence de Wricke (Wi²) a montré que les génotypes Mexicali75 (4.23) et Hoggar (11.07) sont considérés comme les plus stables parmi les dix génotypes testés. Alors qu'en termes d'indice de supériorité (Pi), Polonicum (29,61), Sooty (33,99), Altar84 (34,47) et Mexicali75 (35,37) ont les valeurs les plus faibles de (Pi). L'indice d'adaptabilité géométrique (GAI) a montré que les génotypes Mexicali75 (42,00), Kucuk (40,26) et Altar84 (40,03) sont les plus stables. Les indices non paramétriques Si (2), Si (3), Si (6) ont des corrélations non signifiantes avec le rendement moyen en grains. L’étude de la variabilité génotypique du rendement en grains a montré que Mexicali75 était le génotype qui avait la plus petite variation de rendement au cours des quatre saisons. Globalement, Mexicali75, Hoggar et Kucuk sont les génotypes très stables.

Combretum platypterum belongs to the family of Combretaceae. The leaf is used to treat fever, conjunctivitis, febrifuge, coughs, sexually transmitted diseases, diarrhea, and as a tonic. Despite it being used in ethnomedicine to treat various sicknesses, the safety profile of the leaf extract has not been reported. This study was aimed at testing the acute and sub-acute toxicological assessments of the aqueous leaf extract of Combretum platypterum.The acute study was carried out using mice and rats. In sub-acute experiments, the animals received 0.5, 1, and 2.5 g/kg of the plant extract orally per day for 28 days. The first weight and the last weight were taken. The liver, spleen, kidney, heart, lungs, and stomach were obtained, weighed, and fixed. Blood was obtained for haematology and biochemical assays. The LD50 of the root extract was indeterminable since there was no death in the mice and rats used. The leaf extract significantly increases (p<0.05) the body weight at the dose of 2.5g/kg compared to control. The body weight index was not affected compared to control (p>0.05). At 0.5 and 1 g/kg, the extract significantly increased the level of monocytes (p < 0.05) compared to the control. haematological parameters were not affected. Upon bichemical analysis of the leaf extract, 2.5 g/kg significantly (P<0.05) increased the level of HDL and 0.5 and 1 g/kg significantly (P<0.05) increased the level of TRI compared to control. Other parameters were not affected. This study shows that aqueous root extract is safe.

Authors: Esimai Olapeju , Ogum Emmanuel , Olodu Monday 
Published: March 2023

Purpose: The study determined and compared the prevalence of missed opportunities for immunization among children aged 12-23months in urban and rural areas of southwest, Nigeria. The study identified and compared the associated factors (cultural, religious, ethnic, political and economic).
Methodology: This cross -sectional study was carried out among mothers of children aged 12-23 months, community and opinion leaders in urban and rural areas of southwest, Nigeria. The data was collected using semi structured questionnaire, focus group discussion and in-depth interview guides.
Findings: The prevalence for missed opportunities for immunization was 9.6% with 11.8% in urban as compared with 7.5% in rural areas. The dose specific prevalence of missed opportunities for immunization in rural areas was highest for BCG, HBV0 and OPV0 but lowest for BCG and OPV0 in urban areas. The reasons given in both areas were non-availability of vaccines, long wait time, unscheduled visits, child brought to facility ill but not vaccinated, and distance from the facilities. After controlling for confounders, child factors (age of the child, place of delivery), socio-economic characteristics (mothers and fathers educational and occupational status) were significantly associated with missed opportunities for immunization. Most of the participants of the qualitative survey believed immunization is important as it prevents children from diseases. There were divergent views in both areas on traditions, cultures, and customs as associated factors for missed opportunities for immunization. Government is involved in immunization as reported by participants in both areas.
Conclusion: The study concluded that missed opportunities for immunization is prevalent in both areas and reasons were non-availability of vaccine, unscheduled visits, long wait time and distance from facilities. Parent socioeconomic characteristics, child’s age, place of delivery and mothers receiving immunization messages were the factors associated with missed opportunities for immunization.
Recommendation: There is a need for improvement of quality of interventions and advocacy to the government for continual support for immunization to reduce missed opportunities for immunization.

Two methods were used for the determination of four toxic elements (mercury, arsenic, cadmium and lead) in the Iraqi marine waters. Water samples were collected from eight stations along the Iraqi marine waters. Three stations were selected from nearby zone of the Fao city in southern of Iraq towards Khor Abdullah, these regions were considered as an important navigation line on one hand between Iraq and Iran and on the other hand between Iraq and Kuwait. The other five stations were extended between Umm Qasr port towards Khor Al-Zubair port while the last station was selected from the nearby zone for confluence zone between Khor Al-Zubair port and Shatt Al-Basra canal. All the samples were collected during low tide at depth of 10 cm from surface water. Mercury and arsenic were analyzed by ICP instrument while lead and cadmium were determined through using Atomic absorption spectroscopy (AAS). The recorded data of the total concentration for all the elements have shown the average of concentration as follows: 0.0060 mg/l, 0.0765 mg/l, 0.0518 mg/l and 0.9229 mg/l for metals mercury, arsenic, cadmium and lead respectively. Moreover, some physico-chemical properties of water were recorded in these stations
