ORC proteins in the mammalian zygote [PDF]
Cell and Tissue Research, 2015 The origin recognition complex (ORC) proteins, ORC1-6, are the first known proteins that bind DNA replication origins to mark the competency for the initiation of DNA synthesis. These proteins have complex mechanisms of assembly into the ORC complex and unexpected localizations in the mitotic chromosomes, cytoplasm, and nuclear structures.

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin
Chemistry – A European Journal, EarlyView.The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.

Optimization of a new configuration of power tri-generation cycle by the use of a multi-purpose gene
Journal of Thermal Engineering, 2020 In the current study, a new configuration of power tri-generation cycle was suggested. In this cycle, the energy of hot gases output from the gas cycle in the heat recovery steam generator (HRSG), and the waste energy of the condenser in the steam cycle ...

Connecting ORC and Heterochromatin: Why? [PDF]
Cell Cycle, 2003 Considerable evidence connects heterochromatin or silenced chromatin with the Origin Recognition Complex (ORC) which is needed for initiation of DNA replication. In this review we consider biological forces that might be served by this connection. The prevailing view in the literature is that ORC recruits heterochromatin. This seems paradoxical because

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A steady‐state numerical model is established for a continuous‐flow pH‐TRC for low‐grade waste heat recovery. Based on carbonate and bicarbonate electrolytes, the influences of operating conditions and electrode structure on pH‐driven power generation are clarified.

Energy Science &Engineering, EarlyView.A 4E comparison of PEMFC‐ORC and DMFC‐ORC systems shows that PEMFC‐ORC achieves 21% higher energy efficiency, while DMFC‐ORC obtains 31% higher exergy efficiency and 57% lower levelized cost of electricity. However, DMFC‐ORC emits nearly twice the annual carbon dioxide equivalent of PEMFC‐ORC.

Energy Science &Engineering, EarlyView.A novel combined cooling and power generation system is proposed by integrating organic Rankine cycle (ORC) with an absorption heat transformer, which is driven by combining geothermal energy and data center's waste heat. The system using R601a yielded the best overall performance, achieving an exergy efficiency of 40.34% and an annual cost of 130.29 k$
