Two [4Fe-4S] clusters, FA and FB, function as terminal electron carriers in Photosystem I (PS I), a thylakoid membrane-bound protein-pigment complex. To probe the function of these two clusters in photosynthetic electron transport, site-directed mutants were created in the transformable cyanobacterium Synechocystis sp. PCC 6803. Cysteine ligands in positions 14 or 51 to FB and FA, respectively,...

Purpose The outcome of the present study is to determine variables available at time diagnosis able predict disease reclassification in prostate cancer (PCa) patients on active surveillance (AS). Materials and methods From January 2014 December 2018, 114 consecutive low-risk PCa were enrolled AS protocol according inclusion criteria: PSA ≤ 10 ng/ml, Gleason score (GS) 6 or International Society...

Photosystem I from the cyanobacterium Synechocystis sp. PCC 6803 was examined using the chemical cross-linkers glutaraldehyde and N-ethyl-1-3-[3-(dimethylamino)propyl]carbodiimide to investigate the organization of the polypeptide subunits. Thylakoid membranes and photosystem I, which was isolated by Triton X-100 fractionation, were treated with cross-linking reagents and were resolved using a ...

Abstract Background The PSAD calculating by the serum PSA level divided prostate volume had more specificity and accuracy than for detection of cancer. Methods MRI examinations 319 patients who suspected cancer between January 2014 December 2019 were retrospectively reviewed. Prostate volumes measured images values calculated. optimal cutoff points MRI-based evaluated using receiver operating c...

Most men with prostate cancer will not die from it. Although the most frequent cancer in men in the western world it ranks only 3rd place for cause of death (1). In men over 60 years of age prostate cancer is found at autopsy in over 60% (2). Overdiagnosis by PSA screening is estimated to be 57% when screened until 75 years of age (3). Considering treatment toxicity, careful selection of men fo...
