This novel, timely and cost-competitive book on ‘Wetland Systems to Control
Urban Runoff’ covers water and environmental engineering aspects relevant for
the drainage and treatment of stormwater, wastewater and contaminated natural
watercourses from predominantly urban areas, providing a descriptive overview
of the complex ‘black box’ treatment systems and design issues involved.
The fundamental science and engineering principles of relevant water and
wastewater treatment units and processes are explained to address the student
as well as the professional market.
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
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.
The sodium pump (Na
-ATPase; sodium- and potas-sium-activated adenosine 5¢-triphosphatase; EC 188.8.131.52)
has been under investigation formore than fourdecades.
During this time, the knowledge about the structure and
properties of the enzyme has increased to suchan extent that

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
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.

The aim of this new interdisciplinary series is to promote the exchange of information
between scientists working in different fields, who are involved in the study of complex
systems, and to foster education and training of young scientists entering this rapidly
developing research area.
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
