Obesity is on the rise and the number of end stage renal disease patients who are obese parallel this trend. There is no universally accepted guideline for wait-listing end stage renal disease obese patients in order to reduce surgical complications and improve survival of the kidney graft. Criteria for acceptance are variable among transplant centres, as do post-transplant policies. Careful risk assessment to maximise the benefits of the limited organ donor resource must be undertaken prior to waitlist an obese ki [...]

Hybrid solar thermal systems are considered to be a promising solution for delivering clean thermal energy for the building sector, especially while combining them with other renewable energy sources. Usually, solar energy production does not match the thermal energy demand, and hence the energy storage must be integrated. Thermochemical energy storage is adapted particularly to be used along with solar thermal applications. In this article, the design of the combined solar thermochemical energy storage system is p [...]

A unique two-Pathways process using aqueous sodium glycinate for CO2 capture from a split flue gas stream emitted from 600 MWe post-combustion coal power plant was developed in Aspen Plus v.10. The split gas flow rate used was 44.75 ton/h and contained 0.0023 mol% SO2 and 13.33 mol% CO2. The process includes a washing unit, a CO2 absorption unit, a reverse osmosis unit, and a solvent regeneration unit or an ultrafiltration unit. The washing unit uses deionized water to completely remove SO2 and the CO2 absorption u [...]

United Kingdom guidelines recommend single embryo transfer (fresh or cryopreserved) in the first full assisted conception cycle for women under 40 years most at risk of having twins. Based on a recent randomized clinical trial for women aged 36 to 40 years, the hypothetical effect of preimplantation genetic testing for chromosome aneuploidy was extrapolated to single transfer of every morphologically transferable embryo available from a full cycle. Offering testing to every woman seems likely to result in fewer cli [...]

The main aim of PGS has always been to improve IVF outcome, especially in patient groups assumed to have higher rates of chromosomally abnormal embryos, such as patients of advanced maternal age. In that sense, PGS is quite different from other types of screening as discussed in other papers in this issue.Today it bears no doubt that blastocysts found to be uniformly aneuploid in a biopsy will fail to implant, or worse, will implant and lead to a pregnancy and birth carrying a major chromosomal abnormality, such as [...]

In interest of accurately modelling wellbore production in convective geothermal systems, we draw attention to two approaches to numerical simulation of crustal fluid flow. The historical "strong" approach simulates the fluid mass conservation condition on a localised finite difference mesh approximation to poroelastic continua. The more flexible "weak" approach globally enforces fluid mass conservation by in effect integrating over all numerical mesh cells. Strong formulation crustal flow simulation emerged from n [...]

The kinetics of dearomatization of a kerosene fraction processed using a zeolite catalyst (0.9 HZSM-5) at different temperatures (160-200°C), the molar ratio between the aromatic hydrocarbons present in the kerosene fraction and n-decene (1:(0.5-4)), and the reaction time (1-3 h) were studied. Based on the obtained data, a kinetic model for kerosene dearomatization is proposed. It is assumed that the single-center Riedel mechanism is followed. The stage associated with the interaction between n-decene adsorbed on t [...]

Total pancreatectomy (TP) is performed for not only malignant pancreatic diseases but also benign disease such as chronic pancreatitis or pancreatic injury. However, because this surgery involves removal of the whole pancreas, both exocrine and endocrine pancreatic functions are abolished, significantly impairing the nutritional statuses of patients as well as having other detrimental outcomes. Thus, especially in benign cases additional treatment to recover endocrine function is recommended, as permanent endocrine [...]

Extreme temperatures, drought, and high soil salinity are some of the significant abiotic stresses that can severely impact crop yields, posing a threat to global food production. Comprehensive studies on model plant species are crucial for understanding their biochemical, physiological, and molecular responses to abiotic stresses. Identifying stress response mechanisms and potential targets can aid in developing stress-tolerant crop varieties. Additionally, elucidating the functions of reactive oxygen species is e [...]

All of us are intuitively aware, and many of us explicitly aware as well, of the meaning of geriatrics as a specialty. After all, most of us practice geriatrics or we have been intimately involved with this area and we are know the reality of geriatrics. Or do we? Geriatrics is an oddly ill-defined specialty when you look at it more carefully. Some of us practice medicine, some of us practice in the social sciences, and many of us simply do our jobs day-to-day and try to get by. What we share, however, is the heart [...]

In the 1950’s Denham Harman proposed the Free Radical Theory of Aging whereby species lifespan and individual longevities are the consequence of free radical driven damage to biomolecules. This led to decades of research to ascertain the effect of altered antioxidant defense systems on aging and mortality in an array of species using reverse genetics and dietary manipulation. Within invertebrates, the data generally support the Free Radical Theory in that overexpression of antioxidant enzymes or dietary supplementa [...]
