The African rice midge, Orseolia oryzivora H. & G., is an important insect pest in Burkina Faso. Our study was conducted from 2017 to 2019 in three ir.igated rice schemes including Banzon, Karfiguéla and Vallée du Kou in Western Burkina Faso. The objective of this study was to investigate the ecology of the insect pest. In each rice scheme, four plots of 500 m2 each, spread 50 m apart were randomly selected in farmers’ fields and used for the study. In each plot, a light trap was implemented along one of the diagonals of the plot. Each light trap consisted of a yellow plastic round bowl containing soapy water almost at half the bowl and a torch. The bowl had a capacity of 4.5 l, a diameter of 28 cm and a height of 10.5 cm. The torch had 3 batteries of 1.5 V each, 30 cm long and 1 cm diameter. The torches were lit every night at 6 pm and off at 6 am. Four hundred tillers were collected per month from the cultivated rice and from each of the alternative hosts of the rice midge in order to evaluate the monthly gall count, pre-imaginal populations and parasitism associated with O. oryzivora and its cousin, O. bonzii that is hosted by Paspalum scrobiculatum. The number of O. oryzivora’s adults caught in the light traps was higher during the wet season than the dry season. The level of larval parasitism ranged from 6.16% (Banzon) to 14.29% (Vallée du Kou). The highest level of pupal parasitism (13.73%) was recorded in Vallée du Kou. The damage of O. oryzivora was observed on the wild rice species, O. longistaminata in all three sites. The highest levels of parasitism associated with O. bonzii were recorded in Karfiguéla (20.08% and 25.21% for larval parasitism and pupal parasitism, respectively). These findings are useful in the development of a sustainable control strategy of O. oryzivora.

The breast is a rare localization of extra-pulmonary tuberculosis, even in highly endemic countries. It is most often primitive. The clinical and radiological features are sometimes misleading. It poses diagnostic problems especially with cancer. We report a case of breast tuberculosis having clinical and radiological presentations as a breast carcinoma. Through this observation and a review of the literature, we provide an update on the epidemiological characteristics and the means of diagnosis of this lesion. It was a 52-year-old woman with inflammatory lump of the left breast, adherent to the skin. Ultrasonography and mammography revealed a homogeneous, poorly demarcated nodule of approximately 4 cm of diameter, classified ACR4. Surgical excision was performed. The histological diagnosis was breast tuberculosis. The diagnosis of tuberculous mastitis is made on bacteriological and pathological examinations. Histological examination helps for diagnostic confirmation while excluding a malignant lesion of the breast.

The capacity of 133 fungal endophyte isolates for degrading petroleum hydrocarbons was evaluated. The endophytes were isolated from leaf and stem tissues from 23 plants collected in a natural habitat contaminated with crude oil in southwestern Ecuador. Their.capacity for hydrocarbon biodegradation was tested by an in vitro colorimetric qualitative test during 10 days, using the Minimal Salt Medium and crude oil as the carbon source. Taxonomic identification of the endophytic fungi that showed bioactivity in the qualitative test was carried out by analysis of the ITS gene of the region 18S of the rDNA. Endophytes showed the best results in the previous qualitative test where selected for a quantitative in vitro test for 30 days. Residual hydrocarbons were tracked by infrared spectroscopy (ir. and gas chromatography (GC) with a flame ionization detector. The maximum removal rates of total petroleum hydrocarbons were 99.6% (ir. and 99.8% (GC), corresponding to fungi of the genus Verticillium sp. and Xylaria sp. 1 respectively. This is the fir.t report of biodegradation of crude oil hydrocarbons by endophytic fungi in a tropical ecosystem. The results suggest these fungal isolates are potential hydrocarbon biodegraders that could be used in bioremediation processes.

The hypoglycaemia paraneoplastic is uncommon in diabetic patients. Our aim was to report a case of paraneoplastic hypoglycaemia discovered after the diagnosis of gastric adenocarcinoma in a diabetic patient. A 65 years old man, was hospitalized for the management of acute digestive haemorrhage. In his medical history, he had diabetes since 20 years. He was alcoholic weaned for 3 years and had an unexplored repetitive epigastralgia. During his hospitalization, the exploration of acute digestive haemorrhage found a gastric adenocarcinoma with hepatic metastasis. At the 4th day of his hospitalization, he presented a hypoglycaemic coma with capillary blood glucose at 0.36 g/L. The patient was conscious after the infusion of Hypertonic Glucose Solution (HGS) 10%. After 3 days, the recurrent hypoglycaemia occurred and we intermittently treated by infusion of glucose solution 10%. The measurements of insulin level and C-peptide weren’t performed because they didn’t exist in the city. So, the notion of cancer and the recurrent hypoglycaemia even if we stopped the oral antidiabetic therapy make us think of a paraneoplastic syndrome. The chemotherapy associated with corticosteroid therapy is the standard treatment of the hypoglycaemia paraneoplastic but the patient refused the chemotherapy and we couldn’t use the corticosteroid therapy because of digestive haemorrhage. At the end of his hospitalization, he still had hypoglycaemia treated by infusion of glucose solution 10%. In the absence of means of diagnosis, we should think of paraneoplastic syndrome in front of recurrent hypoglycaemia and cancer in the diabetic patient.

Hydrogen fuel-cell is potential future energy carrier to be implemented on vehicle. However, one of the main problems of its implementation is about how to store Hydrogen in high density at ambient temperature and acceptable pressure. One of the promising storage methods is adsorption on Carbon nanostructured material, one of them is Carbon Nanotube(CNT). However, CNT is still too weak to adsorb Hydrogen gas in ambient temperature. Therefore, many researches have been conducted to find ways to improve Hydrogen physisorption energy on CNT. One of the ways is by doping Lithium cation into CNT. Lithium-cation is expected able to effect electrochemical properties of CNT so that Hydrogen physisorption energy is enhanced. In this study, we performed ab-initio calculations to investigate effect of Lithium-doping on CNT to its Hydrogen physisorption energy. Our research result shows that Lithium-doped CNT have stronger physisorption energy, up to-4.2 kcal/mol, compared to undoped CNT, only-1.2 kcal/mol.
