Limit of viability

Genomic studies of endangered species provide insights into their evolution and demographic history, reveal patterns of genomic erosion that might limit their viability, and offer tools for their effective conservation. The Iberian lynx (Lynx pardinus) is the most endangered felid and a unique example of a species on the brink of extinction.

: Boron is a naturally occurring trace element found in organic and inorganic complexes. Boron-containing compounds are required for living organisms for diverse metabolic functions, including nitrogen fixation in microorganisms, cell wall stability in plants, and bone and carbohydrate metabolism in animals. The number of studies about the effect of boron in biological model systems is very limited; so far, there has been no study on the correlation between boron and amyloid-beta toxicity.

Circulating tumor cells (CTCs) are typically collected into CellSave fixative tubes, which kills the cells, but preserves their morphology. Currently, the clinical utility of CTCs is mostly limited to their enumeration.

Ovarian tissue cryopreservation has a wide range of cancerous indications. Avoiding relapse becomes a specific concern that clinicians frequently encounter. The data about the comparative viability of cancer cells after cryopreservation are limited. This study aimed to evaluate the effect of cryopreservation on breast cancer cells.

Interspecific hybridization in okra is of immense value to exploit the diversity of species in the genus Abelmsochus for developing male sterile lines and/or advance breeding lines possessing resistance to YVMV and ELCV diseases. The present investigation was carried out during the year 2015-16 to study the pattern of interspecific hybridization in genus Ablemoschus involving ten wild species viz., A. angulosus var. angulosus, A. angulosus var. grandiflorus, A. caillei, A. ficulneus, A. manihot ssp. tetraphyllus, A. moschatus, A. tetraphyllus var. pungense, A. tetraphyllus var.

We aimed to explore the shared decision-making context at the limit of viability (weeks 22–25 of gestation) through analyzing neonatologist’s communication strategies with parents and their possible impact on survival and neurodevelopmental impairment (NDI) outcomes.

Survival of preterm neonates has steadily improved over the past five decades, due to changes in the neonatal intensive care. However, in Saudi Arabia, there are no written guidelines on the definition of the lower limit of viability, and there has been a call for such a limit.

The carrot and tomato juice (70:30) with 180Bx inoculated using 10% mixed culture of L. acidophilus and S. boulardii (1:1) and fermented for 20 hours. The microbiological analysis showed that prepared beverage contained optimum level of cultures i.e. 8.5 x109 CFU/mL and yeast and mold 4.5x109 CFU/mL was free from any traces coli-form bacteria. The loss of viability of probiotic cells that is L. acidophilus and Sacchromyces boulardii cultures were observed in beverage stored at refrigeration conditions for 28 days.

Institutional gaps at the country level can be immense. Too often, they have included a lack of documented rights claimed by local people and weak con- sultation processes that have led to uncompensated loss of land rights, espe- cially by vulnerable groups; a limited capacity to assess a proposed project’s technical and economic viability; and a limited capacity to assess or enforce environmental and social safeguards. Such problems are not due to a lack of potential.

Heat transport limitation in larger tissue may also affect survival. Due to the macroscopic size of tissue-engineered products and its finite thermal conductivity, there may be large thermal gradients from the surface to the interior of the samples. The presence of a thermal gradient during cooling and warming phases makes it difficult to choose optimal temperature change protocols for both surface and interior cells. Moreover, osmotic effects (water movement from inside-unfrozen cells to outside-frozen cells) during cooling, reduces cell survival.

Germ cell wastage is a universal phenomenon throughout reproductive life in mammals, including humans. Before puberty and adult life, the vast majority of oocytes become atretic at various stages of follicular development and, of those actually managing to ovulate, only a limited number are capable of repeating the life cycle. Compared to the natural cycle, the situation in controlled ovarian hyperstimulation is substantially aggravated because accidental maturation and ovulation of germ cells of reduced developmental potential may occur (1). ...
