Two hundred and sixty publications from 2007 to 2012 were classified according to the quality of electron micrographs; namely as good (71); mediocre (21); or poor (168). Publications were from 37 countries; appeared in 77 journals; and included micrographs produced with about 60 models of electron microscopes. The quality of the micrographs was not linked to any country; journal; or electron mi...

Shoot meristems used for the study were exercised from the in vitro regenerated shoots cultured on MS medium supplemented with 0.5 mg/L of BAP for multiplication. The sensitivity of the in vitro regenerated was studied using shoot meristems of 0.5 cm. Shoot meristems were cultured on medium containing 10 100 mg/l kanamycin to determine the concentration that was lethal for multiple shoot induct...

The short-time depolarization effects on the integral conductance induced by S. aureus alpha-toxin (ST) in planar lipid bilayer membranes has been studied. Ion channels formed by ST were found to have several potential-induced nonconductance (closed) states. The transitions of ion channels between the states are only through one conductance state. The transition of ST-channels from closed to op...

Celastrus paniculatus, belonging to the family Celastraceae, is an important medicinal plant of India. Owing to the ever-increasing demand from the pharmaceutical industry, the species is being overexploited, thereby threatening its stock in the wild. Poor seed viability coupled with low germination restricts its propagation through sexual means. Thus, alternative approaches such as in vitro te...

Pterocarpus santalinus belongs to fabaceae family and is one of the endemic and endangered medicinal plant species of seshachalam hills, Tirumala, Andhra Pradesh state, India. In the present study we have successfully demonstrated the in vitro regenartion of this plant through shoot bud culture. The seeds germinated sequentially on plastic trays and transferred polythene bags for 21 days served...

We summarize the recent theoretical and numerical works on spin turbulence (ST) in spin-1 spinor Bose-Einstein condensates. When the system is excited from the ground state, it goes through hydrodynamic instability to ST in which the spin density vector has various disordered direction. The properties of ST depend on whether the spin-dependent interaction is ferromagnetic or antiferromagnetic. ...

Vitrification refers to the physical process by which a liquid supercools to very low temperatures and finally solidifies into a metastable glass, without undergoing crystallization at a practical cooling rate. Thus, vitrification is an effective freeze-avoidance mechanism and living tissue cryopreservation is, in most cases, relying on it. As a glass is exceedingly viscous and stops all chemic...
