Digital fundus imaging is being used in diagnosis, documentation, and sharing of many retinal diseases and hence forms an essential part of ophthalmology. The use of smartphones for the same has been ever increasing. There is a need for simpler devices to couple the 20D lens and smartphone so as to take fundus photographs which can help in fundus documentation.

Targeted expression of cystatin restores fertility in cysteine protease induced male sterile tobacco plants.

Fertility restoration in male sterile plants is an essential requirement for their utilization in hybrid seed production. In an earlier investigation, we have demonstrated that the targeted expression of a cysteine protease in tapetal cell layer resulted in complete male sterility in tobacco transgenic plants. In the present investigation, we have used a cystatin gene, which encodes for a cysteine protease inhibitor, from a wild peanut, Arachis diogoi and developed a plant gene based restoration system for cysteine protease induced male sterile transgenic tobacco plants.

CyanoPhyChe: a database for physico-chemical properties, structure and biochemical pathway information of cyanobacterial proteins.

CyanoPhyChe is a user friendly database that one can browse through for physico-chemical properties, structure and biochemical pathway information of cyanobacterial proteins. We downloaded all the protein sequences from the cyanobacterial genome database for calculating the physico-chemical properties, such as molecular weight, net charge of protein, isoelectric point, molar extinction coefficient, canonical variable for solubility, grand average hydropathy, aliphatic index, and number of charged residues. Based on the physico-chemical properties, we provide the polarity, structural stability and probability of a protein entering in to an inclusion body (PEPIB).

Ascaris lumbricoides in the lacrimal passage.

Ascariasis is caused by the roundworm, Ascaris lumbricoides. We report an additional case of live Ascaris lumbricoides removed from the lacrimal puncta of a 10-year-old boy.
