Retrofitted bridge fragility curves provide a powerful tool for assessing the effect of retrofit measures on the seismic performance of different bridge types under a range of loading levels. Traditional methods for retrofit assessment typically evaluate the effectiveness of retrofit based on the performance of individual components. However, the use of fragility curves for retrofitted bridges ...
Skin fragility refers to a large group of conditions in which the ability of the skin to provide protection against trivial mechanical trauma is diminished, resulting in the formation of blisters, erosions, wounds, or scars. Acquired and physiological skin fragility is common; genetic disorders are rare but give insight into the molecular mechanisms ensuring skin stability. The paradigm is repr...
BACKGROUND Fractures associated with bone fragility in older adults signal the potential for secondary fracture. Fragility fractures often precipitate further decline in health and loss of mobility, with high associated costs for patients, families, society and the healthcare system. Promptly initiating a coordinated, comprehensive pharmacological bone health and falls prevention program post-f...
Context: Primary hyperparathyroidism (PHPT) is commonly associated with reduced bone mineral density (BMD) presenting with osteoporosis, increasing the risk of bone fragility fractures in these patients. Bisphosphonates, due to their anti-resorptive action, are known to improve the BMD and reduce the risk of bone fragility fractures. Therefore, bisphosphonates are considered as an alternative t...
The mammalian cochlea is a highly complex structure which contains several cells, including sensory receptor or hair cells. The main function of the cochlear hair cells is to convert the mechanical vibrations of the sound into electrical signals, then these signals travel to the brain along the auditory nerve. Auditory hair cells in some amphibians, reptiles, fish, and birds can regenerate or r...
Background and Aim: Hair loss is one of the most common problems among the skin and hair related diseases. Hair loss can lead to anxiety, depression, low self-esteem and dissatisfaction with appearance. Methods: Patients with androgenetic alopecia who met the eligibility criteria entered the study. Participants were asked to randomly apply a solution of valproic acid 8.3% or a solution of...
Background: Numerous lasers are currently available for hair removal. Objective: To study the efficacy of a pulsed diode laser for removing unwanted hair. Patients and Methods: In this quasi-experimental clinical trial, 39 patients with unwanted hairs on chin referred to Novin-Didegan Laser Center in Tehran were treated with a diode laser system (Palomar, 810nm). Fluences ranging from 40 to 64 ...
Various healthcare guidelines are presented in Islamic tradition regarding human health, one of which is about hair care. The current study aimed to analyze the cleaning and washing approach in hair care with cleansers, such as Henna, Cedrus, Hibiscus, and Katam (Buxus dioica) and their curative and hygienic role. In addition, some dimensions of the medical instructions of the narratives concer...
Strategies to reduce fracture risk must be based on the understanding of the mechanisms that underline the increased incidence of fractures with age and with bone diseases that reduce bone stock. There is evidence that in addition to bone minerals density, other factors influence bone strength. This study reviews the biomechanical aspects of age-related fractures, including the interacting role...
Fragile sites are heritable specific chromosome loci that exhibit an increased frequency of gaps, poor staining, constrictions or breaks when chromosomes are exposed to partial DNA replication inhibition. They constitute areas of chromatin that fail to compact during mitosis. They are classified as rare or common depending on their frequency within the population and are further subdivided on t...
