A 27-year-old married lady, resident of Tamil Nadu (South India), was admitted to the ICU with complaints of low grade fever, weakness, dyspnea on accustomed exertion, swelling of face, hands and feet of 15 days duration. Examination revealed tachycardia, blood pressure of 160/ 100 mmHg, pallor (Hb, 8.2 g%), elevated jugular venous pulse (JVP) and swelling of hands and feet. Imaging of the ches...

Motivated by biological protocols that require transfer of large pieces of DNA into cells, we here review several aspects of osmotic swelling and lysis of semipermeable unilamellar vesicles. Swelling involves a continuous phase transition from a fluctuating flaccid state to a maximum volume turgid state, without a divergent correlation length and with exponents that violate the hyperscaling rel...

Casting is an important part of the postoperative treatment in foot and ankle surgery. Applying a split plaster cast allows for swelling while maintaining surgical correction and alignment. Resecting approximately a 1-in. portion of the plaster cast dorsally and anteriorly maintains stable structural support of the cast while relieving the pressure caused by swelling. We describe a technique fo...

We proposed and experimentally demonstrated a highly sensitive salinity sensor using a polyimide-coated Hi-Bi photonic crystal fiber Sagnac interferometer based on the coating swelling induced radial pressure. This is the first time to exploit fiber coating induced pressure effect for salinity sensing. The achieved salinity sensitivity is 0.742 nm/(mol/L), which is 45 times more sensitive than ...

Cisternostomy is defined as opening the basal cisterns to atmospheric pressure. This technique helps to reduce the intracranial pressure in severe head trauma as well as other conditions when the so-called sudden "brain swelling" troubles the surgeon. We elaborated the surgical anatomy of this procedure as well as the proposed physiology of how cisternostomy works. This novel technique may chan...

Adrenalectomized dogs maintained on desoxycorticosterone acetate developed a fatal circulatory collapse when given normal dog plasma. They showed general restlessness, a rapid fall in blood pressure and cardiac index, a decline in central venous pressure and general prostration. Most dogs developed a bloody diarrhea and a minority showed edematous swelling of the face with itching. Animals with...

The swelling of polyelectrolyte (PE) gels by 1:1 and 2:1 salts is studied via osmotic ensemble Monte Carlo simulations at constant osmotic pressure and electrolyte chemical potential of a reservoir phase in equilibrium with a model PE network. Large molecular weight gels exhibit a remarkable swelling response to small changes in 2:1 salt concentration. Gel collapse is accompanied by the formati...

Sialocele is an uncommon complication of parotidectomy. Most cases resolve after conservative therapy consisting of repeated aspiration and pressure dressing. The condition is, however, occasionally resistant to such therapy. We report on a 52-year-old Chinese man who had a 10-year history of right parotid swelling. Following fine-needle aspiration cytology, Warthin's tumour was diagnosed, but ...

1.1 Abstract Poromechanics offers a consistent theoretical framework for describing the mechanical response of porous solids. When dealing with fully saturated nanoporous materials, which exhibit pores of the nanometer size, additional effects due to adsorption and confinement of the fluid molecules in the smallest pores must be accounted for. From the mechanical point of view, these phenomena ...

The swelling of regular, tightly meshed model networks is investigated by a molecular-dynamics-Monte Carlo hybrid technique. The chemical equilibrium between two simulation boxes representing the gel phase and a solvent bath, respectively, is obtained by subjecting the Lennard-Jones particles of a binary mixture, serving as explicit solvent, to the particle transfer step of Gibbs ensemble-Monte...
