enim Jeans finishing is one of the most important value added activities in the washing plant to meet buyer requirements. It is done by creating numerous effects on it. Potassium Permanganate (PP) is a strong oxidizing agent used to make vintage look with acid stone wash. This present investigation deals with the simultaneous effect of processing time and concentration of PP on the physical and...

Adipogenesis and increase in fat tissue mass are mechanosensitive processes and hence should be influenced by the mechanical properties of adipocytes. We evaluated subcellular effective stiffnesses of adipocytes using atomic force microscopy (AFM) and interferometric phase microscopy (IPM), and we verified the empirical results using finite element (FE) simulations. In the AFM studies, we found...

BACKGROUND Ankle characteristics vary in terms of gait phase and speed change. This study aimed to quantify the components of ankle characteristics, including quasi-stiffness and work in different gait phases and at various speeds. METHODS The kinetic and kinematic data of 20 healthy participants were collected during normal gait at four speeds. Stance moment-angle curves were divided into th...

The objective of this study was to determine the effects of temporal hydrostatic pressure (HP) on the properties of scaffoldless bovine articular cartilage constructs. The study was organized in three phases: First, a suitable control for HP application was identified. Second, 10 MPa static HP was applied at three different timepoints (6-10 days, 10-14 days, and 14-18 days) to identify a window...

CMAJ 2011. DOI:10.1503 /cmaj.090310 A60-year-old woman presented to our emergency department with a one-day history of fever and headache. Her medical history included an appendectomy and a hysterectomy. She was not taking any medications, and she had not recently taken any antibiotics. She had not she received a vaccination against pneumococcus. The night before her visit to the hospital, the ...

Puberty is characterized by a large number of physiological modifications that translate into increased neuromuscular fatigue during high-intensity exercise in adolescents compared to prepubertal children. This greater neuromuscular fatigue in adolescents could be attributed to peripheral (i.e., muscular) and central (i.e., nervous) factors that change through puberty. Among the peripheral chan...

BACKGROUND Neck pain is common, but few studies have used qualitative methods to describe it. PURPOSE To describe the quality, distribution and behavior of neck pain. METHODS Sixteen people (15 females; mean age = 33 years (range = 20-69)) with neck pain >3 months were interviewed using a semi-structured guide. Interview data were recorded and transcribed verbatim. Descriptive content analy...

The neck has a complex anatomical structure and it plays an important role in supporting the head atop the cervical spine, balanced in gravity, while generating the controlled head movements that are essential to so many aspects of human behavior. We have developed a biomechanical model of the human head-neck system that emulates the relevant anatomy. Our model is characterized by appropriate k...

Although microtubules are involved in various pathological conditions of the heart including hypertrophy and congestive heart failure, the mechanical role of microtubules in cardiomyocytes under such conditions is not well understood. In the present study, we measured multiple aspects of the mechanical properties of single cardiomyocytes, including tensile stiffness, transverse (indentation) st...

BACKGROUND First metatarsophalangeal joint (MTPJ) mobility is commonly assessed by its angular displacement (joint angle) or subjectively rated as 'hypermobile', 'normal' or 'stiff' by a clinician. Neither of these methods is ideal because displacement alone does not take into account the force required to displace the joint and subjective evaluation is not always reliable. This study presented...
