The book presents conventional and modern breeding technologies in
the vital areas of animal breeding, to stimulate more research, and
to rapidly pass such modern techniques to scientific community.
Various conventional breeding technologies used for selection and
faster multiplication of superior cattle and buffalo germplasm have
contributed significantly to increase in milk production, which
were mainly due to the technologies developed in the areas of
quantitative genetics and reproductive biology. These included
methodologies for selection of females based upon their expected
producing ability and young males based on the performance of
progeny. Emerging developments in the areas of molecular marker
systems in animals, genome maps, methods of detecting Quantitative
Trait Loci (QTL) linkages, Marker Assisted Selection (MAS) etc.,
are latest tools to be used in breeding programmes for enhancing
the rate of genetic progress. These modern techniques could be of
great help for those traits, for which the conventional
technologies have limitations in their use. Therefore, integration
of molecular markers with conventional breeding technologies
involving pedigree and phenotypic information are probable future
breeding tools for genetic improvement of livestock and poultry.

One of Britain's foremost astrobiologists offers an accessible and
game-changing account of life on Earth. __________________ Why is
all life based on carbon rather than silicon? And beyond Earth,
would life - if it exists - look like our own? __________________
The puzzles of life astound and confuse us like no other mystery.
But in this groundbreaking book, Professor Charles Cockell reveals
how nature is far more understandable and predictable than we would
think. Breathing new life into Darwin's theory of natural
selection, The Equations of Life puts forward an elegant account of
why evolution has taken the paths it has. In a captivating journey
into the forces that shape living things on Earth, Cockell explains
that the fundamental laws of physics constrain nature at every
turn. Fusing the latest in scientific research with fascinating
accounts of the creatures that surround us, this is a compelling
argument about what life can - and can't - be.
Mendel's groundbreaking paper, which laid the foundation for
further research upon heritage and genetics, is published here
complete with the original illustrations and charts. When Mendel
released this paper in 1865, it was after years of rigorous study
and comparison in plant specimens and their offspring. His
conclusion that variant traits were hereditary and could be
determined, with a good degree of accuracy, through probability
analysis were revolutionary in natural science at the time.
Mendel's assertions regarding acquired characteristics,
demonstrated through the comparison of peas and their seeds, would
spark great interest in the nature and mechanisms behind heredity
between generations of organisms. Seeking to gain high quality
results, Mendel prefaces his explanations by noting that he
artificially fertilized the plants described in the work.
This collection vigorously addresses the religious implications of
extreme human enhancement technology. Topics covered include
cutting edge themes, such as moral enhancement, common ground to
both transhumanism and religion, the meaning of death, desire and
transcendence, and virtue ethics. Radical enhancement programs,
advocated by transhumanists, could arguably have a more profound
impact than any other development in human history. Reflecting a
range of opinion about the desirability of extreme enhancement,
leading scholars in the field join with emerging scholars to foster
enhanced conversation on these topics.
Enzymes - Mechanisms, Dynamics and Inhibition, Volume 122, the
latest release in the Advances in Protein Chemistry and Structural
Biology series, highlights new advances in the field, with this new
volume presenting new and interesting chapters on the topics. Each
chapter is written by an international board of authors.
Environmental heat stress is associated with a marked decrease in
orthostatic tolerance (OT), which is defined as the ability to
stand or sit upright without symptoms of dizziness,
lightheadedness, presyncope, or fainting. In most healthy humans,
the autonomic nervous system makes rapid and balanced adjustments
to heart rate and peripheral blood flow, such that most people are
able to stand up "successfully" most of the time, in most
environments. The goal of this book is to discuss various aspects
of the sympathetic neural response to heat stress, how the
sympathetic nervous system coordinates the successful integrative
physiological response to orthostasis, and what happens when it
encounters both challenges simultaneously. We include overviews of
mechanisms of thermoregulation and blood pressure regulation in
humans, with particular focus on control of cardiac output and
neurovascular control mechanisms during heat stress. We discuss the
implications that these changes have for distribution of peripheral
blood flow and, in particular, for blood flow to the cerebral
circulation. The added stressor of dehydration is also discussed,
as it so often goes hand in hand with heat stress. We end with a
brief presentation of countermeasures against the decreases in OT
with heat stress.
The kidney is innervated with efferent sympathetic nerve fibers
reaching the renal vasculature, the tubules, the juxtaglomerular
granular cells, and the renal pelvic wall. The renal sensory nerves
are mainly found in the renal pelvic wall. Increases in efferent
renal sympathetic nerve activity reduce renal blood flow and
urinary sodium excretion by activation of 1-adrenoceptors and
increase renin secretion rate by activation of 1-adrenoceptors. In
response to normal physiological stimulation, changes in efferent
renal sympathetic nerve activity contribute importantly to
homeostatic regulation of sodium and water balance. The renal
mechanosensory nerves are activated by stretch of the renal pelvic
tissue produced by increases in renal pelvic tissue of a magnitude
that may occur during increased urine flow rate. Under normal
conditions, the renal mechanosensory nerves activated by stretch of
the sensory nerves elicits an inhibitory renorenal reflex response
consisting of decreases in efferent renal sympathetic nerve
activity leading to natriuresis. Increasing efferent sympathetic
nerve activity increases afferent renal nerve activity which, in
turn, decreases efferent renal sympathetic nerve activity by
activation of the renorenal reflexes. Thus, activation of the
afferent renal nerves buffers changes in efferent renal sympathetic
nerve activity in the overall goal of maintaining sodium balance.
In pathological conditions of sodium retention, impairment of the
inhibitory renorenal reflexes contributes to an inappropriately
increased efferent renal sympathetic nerve activity in the presence
of sodium retention. In states of renal disease or injury, there is
a shift from inhibitory to excitatory reflexes originating in the
kidney. Studies in essential hypertensive patients have shown that
renal denervation results in long-term reduction in arterial
pressure, suggesting an important role for the efferent and
afferent renal nerves in hypertension.
Although the human genome exists apart from society, knowledge
about it is produced through socially-created language and
interactions. As such, genomicists' thinking is informed by their
inability to escape the wake of the 'race' concept. This book
investigates how racism makes genomics and how genomics makes
racism and 'race,' and the consequences of these constructions.
Specifically, Williams explores how racial ideology works in
genomics. The simple assumption that frames the book is that 'race'
as an ideology justifying a system of oppression is persistently
recreated as a practical and familiar way to understand biological
reality. This book reveals that genomicists' preoccupation with
'race'-regardless of good or ill intent-contributes to its
perception as a category of differences that is scientifically
rigorous.
