An enlarged gauge group acts nonlinearly on the class of nonlinear Schrödinger equations introduced by the author in joint work with Doebner. Here the equations and the group action are displayed in the presence of an external electromagnetic field. All the gauge-invariants are listed for the coupled...

Although trade liberalization is being actively promoted as a key component in development strategies, theoretically, the impact of trade openness on poverty reduction is ambiguous. On the one hand, a more liberalized trade regime is argued to change relative factor prices in favor of the more abundant...

It is estimated that 884 million people do not have access to clean drinking water in the world. Increasing salinity of natural drinking water sources has been reported as one of the many problems that affect low-income countries, but one which has not been fully explored. This problem is exacerbated...

The global boom in premature mortality and morbidity from noncommunicable diseases (NCDs) shares many similarities with pandemics of infectious diseases, yet public health professionals have resisted the adoption of this label. It is increasingly apparent that NCDs are actually communicable conditions,...

Graft-versus-host disease (GvHD) in its acute and chronic forms continues to represent a significant barrier to the success and wide-applicability of blood and marrow transplantation as a potentially curative treatment modality for a number of benign and malignant blood conditions. Presently, calcineurin...

Recently Weber et al. invasively obtained aortic Pulse Wave Velocity (PWV) as a function of age. [1] Systolic and diastolic aortic pressure were determined as well. PWV can be used to derive total arterial compliance, Ctot, as Ctot=k/PWV2. With Ctot and Stroke Volume (SV), aortic Pulse Pressure (PP)...

Rationale: In severe idiopathic pulmonary arterial hypertension, iPAH, pulmonary vascular resistance is increased due to remodeling of the small (resistance) arteries. Most information on arterial remodeling is limited to assessments of averaged increases in wall thickness. Quantitative information on...

Solitons of the parametrically driven, damped nonlinear Schrödinger equation become unstable and seed spatiotemporal chaos for sufficiently large driving amplitudes. We show that the chaos can be suppressed by introducing localized inhomogeneities in the parameters of the equation. The pinning of the...

An eigenvalue problem with a reference function and the corresponding hierarchy of nonlinear evolution equations are proposed. The bi-Hamiltonian structure of the hierarchy is established by using the trace identity. The isospectral problem is nonlinearized as to be finite-dimensional completely integrable...

Background: Interactions of platelets, leukocytes and the vessel wall play pivotal roles in activating coagulation and precipitating thrombosis. High levels of angiotensin II (ATII) cause arterial hypertension by a complex inflammatory pathway requiring leukocyte recruitment and reactive oxygen species...

Abnormal pituitary function was linked to excessive height and acromegaly in the late 19th century. Harvey Cushing proposed a pituitary substance that regulated human linear growth. Chemical characterization of the Growth Hormone (GH) molecule by Li led to a demonstration of its species specificity with...

Calcification of the tunica media of the main pulmonary arteries has been observed in a large proportion of young racehorses. In humans, medial calcification is the most important cause of increased arterial stiffness, and has been implicated in the pathogenesis of microvascular diseases. Pulse wave...

Age and hypertension are major causes of large artery stiffening, a cardiovascular risk factor for heart and kidney damage. Long term hypertension induces vascular remodeling, accelerating vascular aging. The aged Spontaneously Hypertensive Rat (SHR) model is recognized for human cardiovascular pathology...

Using the reservoir-wave approach, previously we characterized pulmonary vasculature mechanics with multiple interventions in a canine model. In the present study, we measured high-fidelity pulmonary arterial (PA) pressure, Doppler flow velocity, and pulmonary capillary wedge pressure in 11 patients...

Orbital lesions vary in their classification, incidence, and presentation depending on the age and geographic distribution. Such lesions in the pediatric age group have been studied extensively because of the possibility of faster progression of orbital involvement and the higher risk of morbidity in...

Background: Antibiotic overuse is influenced by several factors that can only be measured using a valid and reliable psychosocial measurement instrument. This study aims to establish translation and early stage validation of an instrument recently developed by this research team to measure factors influencing...

The study aims to assess the counselling services provided to prevent mother to child transmission of HIV (PMTCT) under the Indian programme of prevention of parent-to-child transmission of HIV (PPTCT). Five hospitals in Delhi providing PMTCT services were randomly selected. A total of 201 post-test...

Good primary care is an essential precondition for a decent healthcare system. In fact, primary health care is at the heart of Universal Health Coverage (UHC). UHC, in turn, is critical to achieve the sustainable development goals. While access to essential medicines is explicit in UHC, access to essential...

Ex vivo human tissue is a valuable research resource. However, if vital methodological information such as anatomical location, tissue processing procedures, or donor characteristics are not reported in scientific literature to a high standard, studies utilising ex vivo human tissue can be difficult...

Measurement of pulse wave velocity is of increasing importance for assessment of arterial stiffness and risk evaluation. Different techniques are available, based either on pressure, distension or Doppler waveforms. Techniques not only differ by the algorithm used to identify specific part of the pulse...

Cyclic stretch is a major contributor of vascular function. However, isolated mouse aortas are frequently studied at low stretch frequency or even isometric conditions. Pacing experiments done in rodents and humans show that arterial compliance is highly cyclic stretch frequency-dependent. The Rodent...

Cytokine release syndrome (CRS) has been increasingly recognized in various conditions including the coronavirus disease 2019 (COVID-19). It is not only associated with systemic inflammatory symptoms, but also hematological complications such as coagulopathy. CRS can affect various components of the...

Visual interactive system (VIS) has been received significant attention for solving various complex problems. However, designing and implementing a novel VIS with the large scale of data is a challenging task. While existing studies have applied various visual analytics (VA) to analyze and visualize...

Aim: Arterial stiffening occurs as part of the natural ageing process, and is thought to be related to the accumulation of collagen and degradation of elastin. However, little is known about how regional variations in arterial structure and mechanical properties contribute to arterial stiffening. This...

Impairment of vascular endothelial function is an early sign of atherosclerosis. An active lifestyle is suggested to be positively associated with favorable endothelial function as opposed to a sedentary lifestyle. The aim of this ongoing study (Lifestyle, Biomarkers and Atherosclerosis Study) is to...

We perform the analytic study of the buoyancy-drag equation with a time-dependent acceleration γ(t) by two methods. We first determine its equivalence class under the point transformations of Roger Liouville, and thus for some values of γ(t) define a time-dependent Hamiltonian from which the buoyancy-drag...
