Nontimber forest products are a source of income for women in rural African communities. However, these products are frequently damaged by insect pests. The present study investigates the diversity and damage rates of insect pests that attack Carapa procera seeds and Lophira lanceolata fruits. The experiment was set up in western Burkina Faso and, for C. carapa, consisted of pests collected from seeds that had fallen to the ground and from stockpiled seeds. For L. lanceolata, pests were collected from fruits on the trees, and on the ground. The collected samples were sent to the laboratory to estimate the proportion of damaged seeds/fruits and rear the insects. The results showed that Ephestia spp., Tribolium castaneum, Oryzeaphilus spp., and Tenebroides mauritanicus were the pests of Carapa procera seeds and Lophira lanceolata fruits. Ephestia spp. was recorded as the main pest of both C. proeera and L. lanceolata, whereas T. castaneum was only detected from seeds of L. lanceolata. For C. procera, the stocks were the most infested （29 %） by Ephestia spp. The infestation rate of fruits of L. lanceolata by Ephestia spp, on trees （31.42 ± 3.75 %） was less than the rate of fruits by T. castaneum on the ground （44.00 ± 3.5 %）. The different body sizes of Ephestia spp. may indicate the occurrence of two putative species, one from C. procera and another one from L. lanceolata. This work provides important information that could contribute to the setting up of a local-scale sustainable management framework for oil tree pests in Burkina Faso and surrounding countries.

Using conventional intra-tumoral radiofrequency ablation(IT-RFA)for the treatment of hepatocellular carcinoma(HCC)3 cm or smaller,high local tumor recurrence rates have been reported(up to 20%)despite initial complete ablation rates reaching 95%.This prompted the recommendation of no touch RFA(NT-RFA)for this indication in clinical practice since 2006(1).The rationale of NT-RFA is based on the assumption that the insertion of electrodes no longer inside but deliberately just outside the borders of the tumors could allow achieving more consistent tumoral ablation with safety margins,hence preventing further secondary local progression from unablated extranodular peripheral microscopic tumoral foci(2).

Three different low-temperature plasma-based methods were used to improve the surface hydrophilicity of polyethy- lene （PE） films, and all the modification processes were carried out by employing an atmospheric pressure plasma jet （APPJ） system. （a） PE films were directly modified by APPJ using a gas mixture of He and 02. （b） Acrylic acid （AA） was introduced into the system and a polymer acrylic acid （PAA） coating was deposited onto the PE films. （c） AA was grafted onto the PE surface activated by plasma pre-treatment. It was found that the hydrophilicity of the PE films was significantly improved for all the three methods. However, the samples modified by Process （a） showed hydrophobicity recovery after a storage time of 20 days while no significant change was found in samples modified by Process （b） and Process （c）. The Fourier transform infrared spectroscopy （FTIR） results indicated that the most intensive C=O peak was detected on the PE surface modified by Process （c）. According to the X-ray photoelectron spectroscopy （XPS） analysis, the ratios of oxygen-containing polar groups for samples modified by Process （b） and Process （c） were higher than that modified by Process （a）.

Microcebus murinus： a novel promising non-human primate model of spinal cord injury

The number of people affected by spinal cord injuries （SCI） ranges from 2.5 to 4 million worldwide. Traumatic SCI induces a primary injury due to initial mechanical impact that causes focal cellular and blood-spinal cord barrier damages. Subsequently, secondary injuries resulting from infiltration of peripheral monocytes, ischemia, edema,inflammation, glial scar and cystic cavities formation as well as excitotoxicity trigger cellular demise and prevent spontaneous axonal regrowth. Secondary damages, including aggregation of extracellular matrix protein at the lesion epicenter, thus greatly amplify impairments induced by the initial mechanical damage.

Interleukin(IL)-33 is a nuclear cytokine in the IL-1 family that is constitutively expressed in the epithelial cells of environmentally exposed tissues(skin,gastrointestinal tract and lungs)and endothelial ***-33 is involved in type 2 innate immunity via the activation of eosinophils,basophils,mast cells,group 2 innate lymphoid cells and macrophages through its receptor ST2(also called IL1RL1)[1].Due to the absence of a secretory signal sequence,IL-33 was thought to be passively released during cell necrosis,physical stress or tissue damage and was accordingly considered an alarmin[2].

Objective: To investigate the cytotoxic, antioxidant and antibacterial activities of ethanolic and aqueous crude extracts of Nerium oleander(N. oleander) leaves. Methods: Cytotoxic activities were evaluated by WST-1 bioassay on two human cancer cell lines, namely human colon adenocarcinoma cell line HT-29 and human breast cancer cell line MDA-MB-231. The antioxidant property of N. oleander extracts was assessed by DPPH scavenging and he agar disc diffusion method was used for the determination of an毬-carotene bleaching tests. Ttimicrobial activity against different strains. Results: Using cell viability indices, the WST-1 test revealed that both extracts reduced cell viability in both cell lines. Our results also showed that aqueous extract was more active than ethanolic extract, with IC50 values of(1.67±0.22) μg/mL and(2.36±0.44) μg/mL on MDA-MB-231 cells, and(2.89±0.35) μg/mL and(5.09±0.52) μg/mL on HT29 cells, respectively. The study of the antioxidant activity showed that N. oleander extracts had a considerable scavenging capacity and exerted a significant preventive effect against the oxidation of 毬-carotene by the peroxide radicals. However, the antibacterial test showed that both ethanolic and aqueous extracts of N. oleander had a moderate antibacterial effect limited only to Gram-positive bacteria. Conclusions: Our results shows that N. oleander aqueous and ethanolic extracts have significant cytotoxic activities against tumor cell lines and possesses a strong antioxidant capacity, suggesting the presence of active compounds in N. oleander leaves that could be a potential source of phytochemicals with high medicinal value to be used in cancer treatment and prevention.
