  • Autumn and winter are cold and flu season -- when people are most likely to catch the viruses that cause influenza and the common cold. Is the old advice true that dressing warmly will help prevent a cold? Or if you do get sick, should you follow the old saying, "Feed a cold and starve a fever"?

  • Public health can be thought of as a series of complex systems. Many things that individual living in high income countries take for granted like the control of infectious disease, clean, potable water, low infant mortality rates require a high functioning systems comprised of numerous actors, locations and interactions to work. Many people only notice public health when that system fails. With widespread globalization occurring, public health issues have become transnational.

  • Allergic Conjunctivitis This condition is extremely common and often mistaken for infectious conjunctivitis. Itching, redness, and epiphora are typical. The palpebral conjunctiva may become hypertropic with giant excrescences called cobblestone papillae. Irritation from contact lenses or any chronic foreign body can also induce formation of cobblestone papillae. Atopic conjunctivitis occurs in subjects with atopic dermatitis or asthma.

  • Clinical Manifestations Most cases of acute sinusitis present after or in conjunction with a viral URI, and it can be difficult to discriminate the clinical features of one from the other. A large proportion of patients with colds have sinus inflammation, although bacterial sinusitis complicates only 0.2–2% of these viral infections. Common presenting symptoms of sinusitis include nasal drainage and congestion, facial pain or pressure, and headache.

  • What is a heat pump? A heat pump is a mechanical device used for heating and cooling which operates on the principle that heat can be pumped from a cooler temperature to a warmer temperature (cold to hot). Heat pumps can draw heat from a number of sources, eg, air, water, or earth, and are most often either air-source or water-source. Although heat pumps have been around for more than a 100 years, the technology has dramatically increased. Not only do heat pumps still operate the common refrigerator, but today, heat pump technology allows us to heat and cool residential...

  • This was the general consensus when I first announced my creative ambitions, twenty years ago. And it didn’t help my commercial prospects that by ‘writer’, I meant ‘poet’. It wasn’t what I wanted to hear. But I knuckled down and got a job in publishing. Not a bad job — the people were nice, the money was OK, bits of the work were interesting. But it made me ill. Literally. I got cold after cold, bug after bug, until I realised it was the job that was bugging me.

  • Diagnosis of acute pediatric sinusitis must be made on the basis of signs, symptoms, and clinical examination. Laboratory tests may be normal even in complicated sinusitis (Pitkäranta et al. 1999; Hytönen et al. 2000), and radiolog- ical fi ndings do not necessarily correlate with a child’s clinical condition. Pathological fi ndings are frequently found in plain radiographs, CT, and MRI of children with common colds, and also in children without symptoms of a respi- ratory infection (Kronemer and McAlister 1997; American Academy of Pediatrics 2001; Schwartz et al.

  • Thehemolysateofthe AntarcticteleostGobionotothen gibberifrons(family Nototheniidae) contains two hemoglo-bins (Hb 1 andHb 2). The concentration of Hb 2 (15–20% of the total hemoglobin content) is higher than that found in most cold-adapted Notothenioidei. Unlike the other Antarctic species so far examined having two hemoglobins, Hb 1 and Hb 2 do not have globin chains in common. Therefore this hemoglobin system is made of four globins (two a-and twob-chains). The complete amino-acid sequence of the two hemoglobins (Hb 1,a 1 2b 1 2 ;Hb 2,a 2 b 2 2 ) has been established. ...

  • A common physiological response of organisms to environmental stresses is the increase in expression of heat shock proteins (Hsps). In insects, this process has been widely examined for heat stress, but the response to cold stress has been far less studied.

  • Cold shock proteins (CSPs) form a family of highly conserved bacterial proteins capable of single-stranded nucleic acid binding. They are suggested to act as RNA chaperones during cold shock inhibiting the formation of RNA secondary structures, which are unfavourable for transcription and translation.

  • Temperature Scales and Classification of Thermometers 1.1 Temperature - Historical Background The concept of temperature makes one think of physiological experiences whilst touching or approaching some solid. Some of them may be described as cold, cool or tepid, others as hot or warm. Warmer bodies transfer heat to other cooler bodies . Both bodies tend to equalise their temperatures, approaching a new common intermediate temperature . Thus the correctness of the definition, given to temperature by the Scotsman James Clerk Maxwell, may be seen .
