The novel coronavirus-induced infection (COVID-19) was declared a pandemic by the World Health Organization onMarch 11, 2020. Iran is one of the countries with a high incidence of COVID-19 infection.Data on three patients with fragility hip fracture and COVID-19 infection were collected from one hospital located inBadrud, Isfahan, Iran, from March 1, 2010, to March 30, 2020. A...

Vulnerability assessment of structures encounter many uncertainties like seismic excitations intensity and response of structures. The most common approach adopted to deal with these uncertainties is vulnerability assessment through fragility functions. Fragility functions exhibit the probability of exceeding a state namely performance-level as a function of seismic intensity. A common approach...

 Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...

We briefly review our findings on the relationship between the fragility of glass formation and cooperative motion, focusing on a simple glass-forming polymer melt. We identify string-like cooperative motions with the hypothetical ‘cooperatively rearranging regions’ of the Adam-Gibbs (AG) description, thereby providing a molecular basis for this interpretation. Moreover, these strings can be de...

The aim of our experiments was to characterise and to validate the osmotic fragility test when applied to human blood samples with no significant alterations of osmotic fragility but with a differentiating shape of the haemolysis curve. All experiments were carried out on human erythrocytes taken from the Regional Centre of Blood Donation and Blood Therapy in Wrocław. The washed erythrocytes we...

Our objective was to estimate the relationship between longitudinal change in BMD and fragility fractures. We studied 3635 women and 1417 men 50-85 yr of age in the Canadian Multicentre Osteoporosis Study who had at least two BMD measurements (lumbar spine, femoral neck, total hip, and trochanter) within the first 5 yr of the study and fragility fractures (any, main, forearm/wrist, ribs, hip) w...

The addition of lead to normal human blood was previously found to cause a decrease in erythrocyte osmotic fragility in vitro. The mechanism of the decreased osmotic fragility caused by lead has not been completely clarified, but the following hypothesis has been proposed. Lead causes a leakage of water from erythrocytes, thus more water can enter the cell before haemolysis occurs. There has be...

When a liquid is cooled below its melting temperature, it usually crystallizes. However, if the quenching rate is fast enough, the system may remain in a disordered state, progressively losing its fluidity upon further cooling. When the time needed for the rearrangement of the local atomic structure reaches approximately 100 seconds, the system becomes "solid" for any practical purpose, and thi...

background: the capacity of human hbaa erythrocytes of non-malarious blood to withstand osmotic stress in the presence of five antimalarial drugs, chloroquine phosphate, quinine, fansidartm, coartemtm and halfantm was studied in vitro. materials and methods: aqueous solutions of four increasing concentrations of the drugs used in this investigation were in the order: 0.2%, 0.4%, 0.6% and 0.8% (...
