  • Medical advances have been occurring at breathtaking speed, with diagnostic and treatment options becoming available for conditions for which none previously existed. However, several aspects of health care remain the same. Patients continue to rely heavily on clinicians for help in understanding the burgeoning evidence in medical research and for providing optimal health care. Clinicians remain steadfast in their quest to meet the needs of their patients and to encourage innovation in meeting those needs.

  • Effective new treatments of heart disease are based on a refined understanding of cellular function and the heart's response to environmental stresses. Not surprisingly therefore, the field of experimental cardiology has experienced a phase of rapid exponential growth during the last decade. The acquisition of new knowledge has been so fast that textbooks of cardiology or textbooks of cardiovascular physiology are often hard-pressed to keep up with the most important conceptual advances.

  • The skin plays an important role in maintaining the integrity of the living organism while allowing the interaction of the organism with its environment. To fulfill these functions, mechanical stability is as important as flexibility. The mechanical properties of skin are very diverse depending on the anatomical location, and they evolve throughout life from the fetus to old age. Both genetic and acquired skin diseases modify skin biomechanics, as do intrinsic and photoaging.

  • Two ORFs encoding a protein related to bacterial dimethylglycine oxidase were cloned from Pyrococcus furiosus DSM 3638. The protein was expressed in Escherichia coli, purified, and shown to be a flavoprotein amine dehydrogenase. The enzyme oxidizes the secondary aminesl-proline, l-pipecolic acid and sarcosine, with optimal catalytic activity towards l-proline.

  • Much work has focused on the electrophysiological properties of transient receptor potential channels. Recently, a novel aspect of importance emerged: the interplay of transient receptor potential channels with the cytoskeleton. Recent data suggest a direct interaction and functional reper-cussion for both binding partners.

  • Smear positive pulmonary tuberculosis patients were diagnosed using the following criteria as per the RNTCP guidelines: (i) Two or three smears positive for AFB and (ii) One sputum smear positive for AFB with radiographic abnormalities consistent with active pulmonary tuberculosis. Smear negative pulmonary tuberculosis was diagnosed if three sputum smears were negative for AFB but evidence of radiographic abnormalities of active tuberculosis was present after two weeks of antibiotic treatment for routine bacterial infections of the respiratory tract19.

  • The small leucine-rich proteoglycans (SLRPs) are involved in many aspects of mammalian biology, both in health and disease. They are now being rec- ognized as key signaling molecules with an expanding repertoire of molecu- lar interactions affecting not only growth factors, but also various receptors involved in controlling cell growth, morphogenesis and immunity.

  • The term ‘antimicrobial peptides’ refers to a large number of peptides first characterized on the basis of their antibiotic and antifungal activities. In addition to their role as endogenous antibiotics, antimicrobial peptides, also called host defense peptides, participate in multiple aspects of immunity (inflammation, wound repair, and regulation of the adaptive immune sys-tem) as well as in maintaining homeostasis.

  • In budding yeast, the protein phosphatase Cdc14 is a key regulator of late mitotic events. Research over the last decade has revealed many of its func-tions and today we know that this protein phosphatase orchestrates several aspects of chromosome segregation and is the key trigger of exit from mitosis.

  • Mechanisms of salt tolerance in halophytes: can crop plants resistance to salinity be improved? High concentrations of sodium are toxic to most plant species, making soil salinity a major abiotic stress in plant productivity world wide. Many crop species, which countless people rely for survival, are negatively affected.

  • Environmental stress deleteriously affects every aspect of an ectotherm’s biological function. Frequent exposure of terrestrial insects to temperature variation has thus led to the evolution of protective biochemical and phy-siological mechanisms. However, the physiological mechanisms underlying the positive impact of fluctuating thermal regimes (FTRs) on the fitness and survival of cold-exposed insects have not been studied.

  • Riftia pachyptila(Vestimentifera) is a giant tubeworm living around the volcanic deep-sea vents of the East Pacific Rise. This animal is devoid of a digestive tract and lives in an intimate symbiosis with a sulfur-oxidizing chemoauto-trophic bacterium. This bacterial endosymbiont is localized in the cells of a richly vascularized organ of the worm: the trophosome.
