We report a rare case of cystic adventitial disease of popliteal artery with venous aneurysm of popliteal vein. A 46-year-old woman had sudden-onset intermittent claudication and coldness in her right leg. The right-sided ankle-brachial pressure index (ABI) was 1.01, but peripheral arterial pulsation was decreased at knee venting position. Computed tomography revealed simple cystic lesion of th...

BACKGROUND Arterial aneurysm is a known complication of syphilis, but the occurrence of femoral artery aneurysm secondary to the syphilitic disease has never been reported. CASE PRESENTATION The present study described a 60-year-old Chinese male who presented with two aneurysms in the middle and lower segment of the right superficial femoral artery causing the symptoms of pain, coldness and n...

Results We report the case of a 72 year old patient with prior stroke without sequelae and hypertensive, with abdominal pain of 7 days duration, high fever and bilious vomiting. Physical examination was marked hypotension (80/45 mmHg), distal coldness, pallor and sweating, 38.5 ° C, 145 spm. The distended abdomen with abolished peristalsis and positive Murphy right upper quadrant. Rest without ...

The laboratory fruit fly, Drosophila melanogaster, is used widely in biological research, but the requirement to maintain stocks with a roughly biweekly generation time imposes substantial burdens of labor, potential cross-contamination and mutation accumulation. The purpose of this study was to assess the impact of prolonged cold stress or milder cooling on survivorship and fertility. The hypo...

This paper presents a thermoeconomic analysis aimed at the optimization of a novel zero-CO2 and other emissions and high-efficiency power and refrigeration cogeneration system, COOLCEP-S (Patent pending), which uses the liquefied natural gas (LNG) coldness during its revaporization. It was predicted that at the turbine inlet temperature (TIT) of 900 C, the energy efficiency of the COOLCEP-S sys...

In flat space, the extreme Reissner-Nordstrøm (RN) black hole is distinguished by its coldness (vanishing Hawking temperature) and its supersymmetry. We examine RN solutions to Einstein-Maxwell theory with a cosmological constant Λ, classifying the cold black holes and, for positive Λ, the " lukewarm " black holes at the same temperature as the de Sitter thermal background. For negative Λ, we c...
