Superconducting Phases in Lithium Decorated Graphene LiC6.

A study of possible superconducting phases of graphene has been constructed in detail. A realistic tight binding model, fit to ab initio calculations, accounts for the Li-decoration of graphene with broken lattice symmetry, and includes s and d symmetry Bloch character that influences the gap symmetries that can arise. The resulting seven hybridized Li-C orbitals that support nine possible bond pairing amplitudes. The gap equation is solved for all possible gap symmetries. One band is weakly dispersive near the Fermi energy along Γ → M where its Bloch wave function has linear combination of [Formula: see text] and dxy character, and is responsible for [Formula: see text] and dxy pairing with lowest pairing energy in our model. These symmetries almost preserve properties from a two band model of pristine graphene. Another part of this band, along K → Γ, is nearly degenerate with upper s band that favors extended s wave pairing which is not found in two band model. Upon electron doping to a critical chemical potential μ1 = 0.22 eV the pairing potential decreases, then increases until a second critical value μ2 = 1.3 eV at which a phase transition to a distorted s-wave occurs. The distortion of d- or s-wave phases are a consequence of decoration which is not appear in two band pristine model. In the pristine graphene these phases convert to usual d-wave or extended s-wave pairing

Mixed sugar fermentation by Pichia stipitis, Sacharomyces cerevisiaea, and an isolated xylosefermenting Kluyveromyces marxianus and their cocultures

A yeast strain with higher rates and yields in the fermentation of glucose, mannose and galactose in semiaerobic conditions than Pichia stipitis and Sacharomyces cerevisiae and ethanol tolerance than P.stipitis, was isolated from sugarcane baggase from Iranian resources. This strain that can ferment xylose with lower rates and yields than P. stipitis is characterized as Kluyveromyces marxianus. Theability of K. marxianus to ferment mixed sugars comprised of 30 g/l glucose, 30 g/l xylose, 12 g/l mannose and 8 g/l galactose (total sugar 80 g/l), as a model of many hydrolysates, were compared to P.stipitis and S. cerevisiae and then a coculture of P. stipitis and S. cerevisiae was compared with a coculture of P. stipitis and K. marxianus. In mixed sugars fermentation with individual yeasts P. stipitis shows the highest yield (0.40 gg-1) and maximum ethanol (30.23 gl-1), but K. marxianus shows the highest Qpmax (1.09 gl-1h-1) and substrate utilization efficiency (E,>99%). P. stipiti and K. marxianus coculture shows the best results with high yield (0.42 gg-1) and maximum ethanol (31.87 gl-1), Qpmax (1.09 gl-1h-1) and substrate utilization efficiency (E,>99%). Because of the higher rates and yields of K. marxianus to ferment hexoses than P. stipitis and its higher ethanol tolerance, K. marxianus helps the P. stipitis to reach the concentration higher than 30 g/l ethanol concentration

Survey of Third-Party Parenting Options Associated With Fertility Preservation Available to Patients With Cancer Around the Globe

Purpose: In the accompanying article, “Analysis of Fertility Preservation Options Available to Patients With Cancer Around the Globe,” we showed that specific fertility preservation services may not be offered at various sites around the world because of cultural and legal barriers. We assessed global and regional experiences as well as the legal status of third-party reproduction and adoption to serve as a comprehensive international data set and resource for groups that wish to begin oncofertility interventions. Methods: We provide data on the legalities of third-party assisted reproductive technologies and other family-building options in the 28 oncofertility-practicing countries surveyed. Results: We found regional and country differences that will be important in the development of tailored resources for physicians and for patient brochures that are sensitive to these local restrictions and cultural norms. Conclusion: Because many patients first consult Web-based materials, the formal assessment of the availability of these options provides members of the global oncofertility community with data to which they might otherwise not have ready access to better serve their patients

A survey of fertility preservation options available to cancer patients around the globe

Purpose: Oncofertility focuses on providing fertility and endocrine-sparing options to patients who undergo life-preserving but gonadotoxic cancer treatment. The resources needed to meet patient demand often are fragmented along disciplinary lines. We quantify assets and gaps in oncofertility care on a global scale. Methods: Survey-based questionnaires were provided to 191 members of the Oncofertility Consortium Global Partners Network, a National Institutes of Health–funded organization. Responses were analyzed to measure trends and regional subtleties about patient oncofertility experiences and to analyze barriers to care at sites that provide oncofertility services. Results: Sixty-three responses were received (response rate, 25%), and 40 were analyzed from oncofertility centers in 28 countries. Thirty of 40 survey results (75%) showed that formal referral processes and psychological care are provided to patients at the majority of sites. Fourteen of 23 respondents (61%) stated that some fertility preservation services are not offered because of cultural and legal barriers. The growth of oncofertility and its capacity to improve the lives of cancer survivors around the globe relies on concentrated efforts to increase awareness, promote collaboration, share best practices, and advocate for research funding. Conclusion: This survey reveals global and regional successes and challenges and provides insight into what is needed to advance the field and make the discussion of fertility preservation and endocrine health a standard component of the cancer treatment plan. As the field of oncofertility continues to develop around the globe, regular assessment of both international and regional barriers to quality care must continue to guide process improvements
