the condensation of glyoxal with benzylamine in the presence of formaldehyde leads to 2,4,6,8-tetrabenzyl-2,4,6,8-tetraazabicyclo [3.3.0] octan (6) in methanol. the scopes and limitations of the reaction have been determined. at low temperatures, a mixture of (6) and diol (7) is formed.

Senescence is a well-known cellular event characterized by specific markers like permanent cell proliferation arrest and the secretion of messenger molecules forming Senescence-Associated Secretory Phenotype (SASP). The SASP composition depends on many factors such as type nature stress that induced senescence. Since skin constitutes barrier with external environment, it particularly subjected ...

Biogenic volatile organic compounds (BVOC), which are mainly emitted from plants, a major precursor for the formation of ground-level ozone (O 3 ) and secondary aerosols (SOA). In northern region Thailand, 63.8% land area is covered by forests. Herein we investigated effects biogenic (BVOC) plants anthropogenic NO x emissions on fine particulate matters (PM 2.5 formation. The Weather Research F...
