Capillary hemangioma of tympanic cleft

We present an extensive capillary hemangioma of right ear in an 11-year-old child involving external auditory canal, middle ear and mastoid. Patient was presented with chronic purulent discharge and aural mass in right ear. The Computarize tomography (CT) scan revealed enhancing soft tissue filled density in external ear, middle ear and mastoid for that modified radical mastoidectomy (MRM) was done. The histopathological report of surgical specimen confirmed the diagnosis of capillary hemangiom

Intermediate regimes in granular Brownian motion: Superdiffusion and subdiffusion

Brownian motion in a granular gas in a homogeneous cooling state is studied theoretically and by means of molecular dynamics. We use the simplest first-principle model for the impact-velocity dependent restitution coefficient, as it follows for the model of viscoelastic spheres. We reveal that for a wide range of initial conditions the ratio of granular temperatures of Brownian and bath particles demonstrates complicated non-monotonous behavior, which results in transition between different regimes of Brownian dynamics: It starts from the ballistic motion, switches later to superballistic one and turns at still later times into subdiffusion; eventually normal diffusion is achieved. Our theory agrees very well with the MD results, although extreme computational costs prevented to detect the final diffusion regime. Qualitatively, the reported intermediate diffusion regimes are generic for granular gases with any realistic dependence of the restitution coefficient on the impact velocity

Experimental evidence for three universality classes for reaction fronts in disordered flows

Self-sustained reaction fronts in a disordered medium subject to an external flow display self-affine roughening, pinning and depinning transitions. We measure spatial and temporal fluctuations of the front in $1+1$ dimensions, controlled by a single parameter, the mean flow velocity. Three distinct universality classes are observed, consistent with the Kardar-Parisi-Zhang (KPZ) class for fast advancing or receding fronts, the quenched KPZ class (positive-qKPZ) when the mean flow approximately cancels the reaction rate, and the negative-qKPZ class for slowly receding fronts. Both quenched KPZ classes exhibit distinct depinning transitions, in agreement with the theory

Corona virus pandemic: current scenario and future hopes

Whenever we human beings challenge the existence of the god or tried to prove ourselves superior to the nature. The Nature bounces back in the form of these pandemics of infectious disease which forced us to either surrender or to lockdown ourselves in homes. The current outbreak of Corona Virus Disease-19 (COVID-19) is the same warning from nature. It is spreading very fast from one country to other and almost affects the whole world. We have many unanswered questions. Currently in absence of any definitive treatment, prevention is an only option. But future hopes are still there. This article gives a brief and accurate detail of COVID-19 pandemic regarding current situation and future hopes

Gauging the Antiobesity Potential of Oral Semaglutide in Type 2 Diabetes in the Indian Context

“Diabesity”, which combines type 2 diabetes (T2D) and obesity has emerged as a global epidemic in the modern world. Indeed, diabesity contributes significantly to increased morbidity, and the prevalence of this global health burden has steadily increased in India over the past three decades. Importantly, only a few pharmacological agents are currently available across the world, and India in particular has access to only a limited number of such agents. However, with the advent of oral glucagon-like peptide-1 receptor agonist (GLP-1RA) after its launch in India recently as an antidiabetic agent, the horizon to combat diabesity has expanded. With the available evidence from several phase 3 trials of oral GLP-1RA (PIONEER, Peptide Innovation for Early Diabetes Treatment), it is increasingly becoming apparent that oral semaglutide could have some potential to fulfil the US Food and Drug Administration criterion of an antiobesity agent
