Polymyalgia rheumatica (PMR) is an age-related chronic inflammatory disease with rheumatic features at the fore. In addition to the high-grade systemic inflammation, it is characterized by typical "polymyalgic" musculoskeletal symptoms, including diffuse and severe pain and prolonged morning stiffness of the shoulder girdle, pelvic girdle, and neck. PMR is a member of the so-called giant cell arteritis complex; however, in spite of the marked systemic inflammation in PMR, the local vasculitis process aborts. The pa [...]

Cytochrome P450 2J2 (CYP2J2) is one of the recently discovered enzymes that is involved in the metabolism of several drugs. It is mainly an extrahepatic enzyme which can, to some extent, explain some the drugs’ side effects such as cyclophosphamide (Cy). Cyclophosphamide is an alkylating agent that is commonly used in conditioning prior to stem cell transplantation. It is a prodrug that is bio-activated by several CYPs including CYP2J2. Cy is known to have several side effects and its extrahepatic activation by CYP [...]

The authors attempted to operationalize the clinical work of strategic theorist and expert family therapist, Scott Browning. Strategic therapy takes the position that a client is stuck, not necessarily sick. This focus encourages the clinician to create alternative perspectives such that a client learns to consider a problem from a new lens. Milton Erickson, a progenitor of strategic thinking, used hypnosis and paradox to nudge clients toward a useful alternative perspective [1]. The present article examined three [...]

In this study, we investigated the degradation of amido black dye in an aqueous solution using ultra-violet (UV) light catalyzed by iron oxide nanoparticles (nano-Fe). The nano-Fe was synthesized by sodium borohydride reduction of ferric chloride solution and was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray fluorescence spectrophotometry (XRF). The SEM of the nano-Fe showed regular spherical particles, the XRD examination showed a weak and broad peak at Fe (1 1 0), and the [...]

Cerebral palsy is defined as “A group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, perception, cognition, communication, and behavior, by epilepsy, and by secondary musculoskeletal problems [1].” Between 30-40% of people with cerebral palsy also have epilepsy [2,3,4]. Som [...]

Flavonoids are phytochemicals (polyphenols) of plant origin. They can trap free oxygen radicals generated by mitochondria and other electronic transport chains, thereby inhibiting inflammatory and carcinogenic changes in vivo and in vitro. Why the body requires these compounds for the well-being of the organism and the maintenance of human health remains unclear. However, a deficit of flavonoids could lead to molecular malfunctions in cells, organelles, and macromolecules. This manuscript describes the occurrence a [...]

Positive perceptions of pregnancy are associated with better postpartum outcomes, including stronger relationship with baby. Although better self-reported emotional availability (EA-SR) is associated with greater attachment security with infants, research has not yet explored the relationship between prenatal maternal factors and EA-SR. The aim of the study was to explore the associations between prenatal variables (adult attachment, shame, compassion) and EA-SR at 3- and 6-months postpartum. A cross-sectional surv [...]

In this study, we present selective hydrocracking of poly (di and tri) aromatic compounds to monoaromatics, such as benzene, toluene, and xylenes (BTX), over a mixture of Pt/Al2O3 and Y zeolites. The polyaromatic compounds feed is a combined simulated model feed, which is similar to light cycle oil (LCO) in composition. The feed is processed in a fixed bed reactor over a catalyst mixture: in the first step, selective hydrogenation of di and tri-aromatic compounds occurs in the presence of Pt/Al2O3 catalyst, followe [...]

The carbon footprint of motorized transport modes per unit length traveled encompasses the unit share of the vehicle lifetime emissions, that of the transport infrastructure, and those of the motor energy, considered both from “well to tank” and from “tank to wheel”. In the active modes of transport, i.e., walking and cycling, the counterpart of motor energy is human energy, which is associated with two kinds of carbon flows: the carbon footprint of food intake, – which we call the Food to Body component – and the [...]

Reducing and conserving fuel usage is pivotal for any engineering system for the development of a sustainable energy solution. Proton exchange membrane fuel cells (PEMFCs) are one of the promising renewable energy systems that consume hydrogen as their source of fuel to generate electricity. This paper investigate the necessity of the constant supply of fuel (hydrogen) in the PEMFC system to ensure stable operation. We propose that a dynamic supply of fuel could help achieve similar performance and reduce the amoun [...]
