Nitrogenous heterocyclic compounds are key pollutants in coking wastewater; however, the functional potential of microbial communities for biodegradation of such contaminants during biological treatment is still elusive. Herein, a high throughput functional gene array（Geo Chip 5.0）in combination with Illumina Hi Seq2500 sequencing was used to compare and characterize the microbial community functional structure in a long run（500 days） bench scale bioreactor treating coking wastewater, with a control system treating synthetic wastewater. Despite the inhibitory toxic pollutants, Geo Chip 5.0 detected almost all key functional gene（average61,940 genes） categories in the coking wastewater sludge. With higher abundance, aromatic ring cleavage dioxygenase genes including multi ring1,2 diox; one ring2,3 diox; catechol represented significant functional potential for degradation of aromatic pollutants which was further confirmed by Illumina Hi Seq2500 analysis results. Response ratio analysis revealed that three nitrogenous compound degrading genes-nbz A（nitro-aromatics）, tdn B（aniline）, and scn ABC（thiocyanate） were unique for coking wastewater treatment, which might be strong cause to increase ammonia level during the aerobic process. Additionally, Hi Seq2500 elucidated carbozole and isoquinoline degradation genes in the system. These findings expanded our understanding on functional potential of microbial communities to remove organic nitrogenous pollutants;hence it will be useful in optimization strategies for biological treatment of coking wastewater.

Plant growth hormone BAP (benzyl amino purine), KIN (kinetin), NAA (1-naphthalene acetic acid) and IBA (indole-3 butyric acid) effect was studied on in vitro multiplication of shoots and rooting of Drepanostachyum falcatum. In vitro micropropagation of himalayan weeping bamboo is explained by in vitro shoot induction and proliferation. Excised explant with axillary bud is surface sterilized with 0.1% HgCl2 for 10 - 12 minutes, cleaned with 90% ethanol and inoculated on liquid Murashige and Skoog (MS) culture medium supplemented with different concentrations of BAP/ KIN. Effect of BAP/KIN on shoot induction is with different rate and number of shoots produced by explants with axillary bud cultured on MS media supplemented with 0.0 mg/l BAP/KIN - 5.5 mg/l BAP/KIN. Shoot multiplication with highest rate is achieved on MS medium supplemented with 3.5 mg/l BAP after 4th sub-culturing. The most effective with highest rate and number of root induction combination is 6.5 mg/l IBA after 5 weeks. The roots produced by 6.5 mg/l IBA is best compared with other combination of auxin NAA (1-naphthalene acetic acid).

Geochemical studies of sandstones from the three lithostratigraphic successions in the southern Benue Trough of Nigeria were undertaken for a geochemical characterization of the sandstones, and to assess their strati-graphic and source evolution. Major and trace elements data were obtained from outcrop sandstone samples. The SiO2/Al2O3, Fe2O3/K2O ratios and CaO contents have been used to characterize the Cretaceous sandstones into Al-rich and high and low Fe2O3/K2O ratio sandstones. Results indicate that there are geochemical features that display stratigraphic trends across the succession from the Asu River Group, Eze-Aku Group to the proto-Niger Delta succession which may imply a discontinuous evolution from different source terrains of Precambrian and Mesozoic ages that supplied the sediments. The Asu River Group sandstones have lower SiO2, Al2O3, Fe2O3 and higher MgO; the Eze-Aku sandstones have higher TiO2, CaO, alkalis and lower MgO while the proto-Niger Delta sandstones have higher SiO2, Al2O3, Fe2O3 and lower alkalis and CaO. These discontinuities signify the influence of tectonic impulses that af- fected the southern Benue Trough during the Cretaceous time. Changes in ratios of TiO2/Al2O3, Fe2O3, Cr and Zr suggest an increasingly mafic contribution to the depositional basin with time. The chemical index of alteration increases with time, possibly suggesting that a more intense weathering regime in the hinterland developed with time.

This perspective shows an attempt to obtain synergy effects to fight ischemic stroke by combining agents acting on two different homeostatic mechanisms:inflammation and unfolded protein response (Anuncibay-Soto et al.,2018).Different pharmacological approaches have been assayed to alleviate cerebrovascular accident (stroke), which represents one of the most devastating diseases in the elderly.
