Ebook "Hematopoietic stem cell development" brings together articles covering the biology of hematopoietic stem cells during embryonic development, reporting particular aspects of fly, fish, avian and mammalian models. Thus, this book allows a comparative overview of hematopoietic stem cell generation in the different classes, emphasizing the conserved trends in development. This book culminates with state-of –the art knowledge on hematopoietic development in human species and discussions of the most recent breakthroughs with relevance to both researchers and clinicians.

The venom of two dominant species of wolf spiders, Pardosa sumatrana Thorell and Pardosa birmanica Simon, was extracted and characterized. Insecticidal potential of crude venom and selected peptide fractions (i.e. 35-kDa fraction of both spiders) was evaluated in the laboratory using Rhopalosiphum padi (Linnaeus) (Homoptera: Aphididae) as a model pest. Results of the study showed that both the crude venom and the protein fractions caused significantly higher mortality in treated aphids compared to the control.

Anurans are the most suitable vertebrate group to see the development and also evolution in the skull, compared to other terrestrial vertebrates as they show highly derived morphology. For this reason, the cranium of anurans has been widely used for analyzing e.g., development and integration, evolutionary history, phylogenetic relationships, sexual dimorphism; and for taxon determination. We applied geometric morphometric techniques and then multivariate statistical analyses to see the skull size and shape variations in closely related Bufo species (B. bufo and B.

The study was carried out to evaluate fifty-six accessions/species suitable for industrial purpose. Understanding the bioactive compound diversity among both the shatavari species, Asparagus racemosus (AR) and A. adscendens (AA) are an important species for crop development. Sufficient variation for bioactive compounds (shatavarin IV) were registered in both the species. AR and AA confined average 22.84 µg g–1 and 117.74 µg g–1 shatavarin IV, respectively. The A. adscendens produced about five-folds higher shatavarin IV content as compared to A. racemosus.

Avian poxviruses are important pathogens of both wild and domestic birds. To date, seven isolates from subclades A and B and one from proposed subclade E, have had their genomes completely sequenced. The genomes of these isolates have been shown to exhibit typical poxvirus genome characteristics with conserved central regions and more variable terminal regions. Infection with avian poxviruses (APVs) has been reported in three species of captive flamingo, as well as a free-living, lesser flamingo at Kamfers dam, near Kimberley, South Africa.

The renewed interest in epigenetics has led to the understanding that both the environment and individual lifestyle can directly interact with the epigenome to influence its dynamics. Epigenetic phenomena are mediated by DNA methylation, stable chromatin modifications and non-coding RNA-associated gene silencing involving specific proteins called epigenetic factors.

The wild relatives of crop species represent a potentially valuable source of novel genetic variation, particularly in the context of improving the crop’s level of tolerance to abiotic stress. The mechanistic basis of these tolerances remains largely unexplored. Here, the focus was to characterize the transcriptomic response of the nodes (meristematic tissue) of couch grass (a relative of barley) to dehydration stress, and to compare it to that of the barley crown formed by both a drought tolerant and a drought sensitive barley cultivar.

The Hafnia genus is an opportunistic pathogen that has been implicated in both nosocomial and community-acquired infections. Although Hafnia is fairly often isolated from clinical material, its taxonomy has remained an unsolved riddle, and the involvement and importance of Hafnia in human disease is also uncertain.

Growth rate is one of the most important features for aquaculture species and deciphering its regulation mechanism has great significance both in genetics and in economics. Hypothalamus-pituitary growth axis (HP growth axis) or neuro-endocrine axis plays a vital role in growth regulation in different aquaculture animals.

Researchers often measure changes in gene expression across conditions to better understand the shared functional roles and regulatory mechanisms of different genes. Analogous to this is comparing gene expression across species, which can improve our understanding of the evolutionary processes shaping the evolution of both individual genes and functional pathways.

Sunflower (Helianthus annuus L.) is one of the important oilseed crop, with comparatively narrow genetic base. To broaden the genetic base wild species have been used through wide hybridization. Generally wide hybridization comes with linkage drags which contribute several undesirable traits to cultivated species. In the present study, comparative analysis of backcross (BC2F3) and selfed (BC1F4) progenies was carried out to know the extent of variability in desirable direction created in both the generation derived from wide hybridization.

Evolvulus nummularius, is ethnomedicinally used as a medicine for hysteria, to cure burns, cuts, wounds and scropion stings. This plant has antihelminthic activity, wound healing activity, poor sedative and anticonvulsant properties. In this study, the antibacterial activity of crude methanol extract of E. nummularius was studied against three gram negative multidrug resistant strains E. aerogenes, P. aeruginosa and K. pneumoniae. This plant extract showed both bacteriostatic and bactericidal activity against all these bacterial strains. The extract was most active against E. aerogenes.

Mango malformation, a century old malady of Mangifera indica, is considered as the major constraints for mango production worldwide. Several reports claimed that Fusarium species particularly Fusarium mangiferae is associated with mango malformation. Salicylic acid is an important signaling molecule that plays crucial role in plant microbial interactions. The present study was conducted to observe in-vitro application of different concentrations of salicylic acid on mycelial growth and conidial germination of two isolates of Fusarium mangiferae.

A novel technique based on photocatalysis was applied to eliminate chromium ions, a toxic hazardous environmental pollutant. The photoreduction of each species of chromium (total, hexavalent, and trivalent chromiums) from chrome-electroplating wastewater was investigated using a titanium dioxide suspension under irradiation by a low-pressure mercury lamp. The initial concentration of total chromium was 300 mg/l. The applied conditions were the direct photocatalytic reduction process at pH 3.65 and the indirect photocatalytic reduction with added hole scavengers at the same solution pH.

Scanning electron micrographic observations of renal arteries of goat and pig which revealed a thin tunica intima enveloped by packed layer of smooth muscle cells in media in both species. Endothelium was wavy in outline on internal aspect of renal arteries in goats and pigs. It presented cushion like foldings which were aligned across the longitudinal axis of the artery. Outer parts of tunica media were anchored by fine collagen fibrils and elastic fibers to the collagen tissue in adventitia. In case of pig, tunica adventitia of renal arteries was relatively thicker than that of the goat.

In flamingo and great Indian horned owl, the ilium was elongated in shape and consisted of preacetabular and post acetabular parts. The preacetabular part of the ilium in both the species of the present study was quadrilateral in shape. The ischium was flat, almost triangular in outline and was situated ventral to the post acetabular part of the ilium in both species.
