1.Crystal structure analysis of C-phycoerythrin from marine cyanobacterium Phormidium sp. A09DM.
Kumar V1, Sonani RR2, Sharma M3, Gupta GD3, Madamwar D4. Photosynth Res. 2016 Apr 11. [Epub ahead of print]
The role of unique sequence features of C-phycoerythrin, isolated from Phormidium sp. A09DM, has been investigated by crystallographic studies. Two conserved indels (i.e. inserts or deletions) are found in the β-subunit of Phormidium phycoerythrin that are distinctive characteristics of large number of cyanobacterial sequences. The identified signatures are a two-residue deletion from position 21 and a nine-residue insertion at position 146. Crystals of Phormidium phycoerythrin were obtained at pH values of 5 and 8.5, and structures have been resolved to high precision at 1.95 and 2.1 Å resolution, respectively. In both the structures, heterodimers of α- and β- subunits assemble as hexamers. The 7-residue insertion at position 146 significantly reduces solvent exposure of π-conjugated A-C rings of a phycoerythrobilin (PEB) chromophore, and can influence energy absorption and energy transfer characteristics. The structural analyses (with 12-fold redundancy) suggest that protein micro-environment alone dictates the conformation of bound chromophores.

BACKGROUND: Although over the past decade the management of invasive fungal infection has improved, considerable controversy persists regarding antifungal prophylaxis in solid organ transplant recipients.
3.PDielec: The calculation of infrared and terahertz absorption for powdered crystals.
Kendrick J1, Burnett AD2,3. J Comput Chem. 2016 Apr 13. doi: 10.1002/jcc.24344. [Epub ahead of print]
The Python package PDielec is described, which calculates the infrared absorption characteristics of a crystalline material supported in a non-absorbing medium. PDielec post processes solid-state quantum mechanical and molecular mechanical calculations of the phonons and dielectric response of the crystalline material. Using an effective medium method, the package calculates the internal electric field arising from different particle morphologies and calculates the resulting shift in absorption frequency and intensity arising from the coupling between a phonon and the internal field. The theory of the approach is described, followed by a description of the implementation within PDielec. Finally, a section providing several examples of its application is given. © 2016 The Authors.

4.Radiation-induced low-grade fibromyxoid sarcoma of the chest wall nine years subsequent to radiotherapy for breast carcinoma: A case report.
Shibata S1, Shiraishi K2, Yamashita H2, Kobayashi R2, Nakagawa K2. Oncol Lett. 2016 Apr;11(4):2520-2524. Epub 2016 Feb 10.
The present study reports a case of low-grade fibromyxoid sarcoma that occurred in a 62-year-old woman 9 years subsequent to whole breast irradiation for a carcinoma of the left breast, and 18 years following chemotherapy and radiotherapy (RT) for non-Hodgkin's lymphoma (NHL; diagnosed at the age of 43). The patient was 53 years of age when a cT2N0M0 stage IIA breast tumor was identified and excised. A 2.5 cm diameter nodule with dimpling in the upper-outer region of the left breast was detected. Pathological examination revealed that the tumor was an invasive ductal carcinoma, of a solid tubular type. The patient was treated with post-surgical whole breast RT. The left breast received 46 Gy in 23 fractions (2 Gy per fraction) for 4 weeks and 3 days, followed by a cone down boost of 14 Gy in 7 fractions (2 Gy per fraction); therefore a total dose of 60 Gy in 30 fractions was administered. In total, 9 years subsequent to RT, the patient observed a small lump in the left chest wall.
