Assessing sweet sorghum juice and syrup quality and fermentation efficiency
No full textSweet sorghum is a C4 crop with high photosynthetic efficiency with a unique
ability of high carbon assimilation (50 g m-2 day-1) and accumulates high
concentrations of easily fermentable sugars (glucose, fructose and sucrose)
in the stalks. Hence, it is widely believed that it is an alternate energy source
that is renewable, sustainable, efficient, cost-effective, convenient and safe to
use. Sucrose is the major sugar in sweet sorghum juice which constitutes up
to 85% of the total sugars (Woods 2000). The sugar yields ranged between
1.6 to 13.2 Mg ha-1, with significant variations observed between years and
regions (Jackson et al. 1980; Reddy et al. 2007; Zhao et al. 2009). The juice
sugar content is dependent on the crop stage, because fructose is more
abundant at the early development stage, whereas sucrose tends to be
dominant after heading (Sipos et al. 2009). The sweet sorghum juice sugar
content ranged from 10 to 25 Brix% at maturity (Reddy et al. 2007; Ritter
et al. 2004). Research at the International Crops Research Institute for the
Semi-Arid-Tropics (ICRISAT) showed that sweet sorghum juice yield ranges
between 16.8 to 27.2 m3 ha-1 (Reddy et al. 2007) and accrues about 23%
additional returns vis-à-vis grain sorghum (Rao et al. 2009)

Optimization of Growth Parameters of Naphthalene Degrading Bacteria Isolated From Oil Contaminated Soils
No full textPolycyclic aromatic hydrocarbons PAHs released from various sources are reaching the environment. They are hazardous to vegetation and human health. The PAHs are carcinogenic and mutagenic. They cause various disorders among humans. Bioremediation which makes use of microbes to degrade such PAHs is a safe approach to remove PAHs from environment. The naphthalene is considered as model compound for PAHs biodegradation studies. In the present work three naphthalene degrading bacterial isolates viz., Bacillus, Micrococcus and Pseudomonas were grown in BSM broth supplemented with naphthalene and physical parameters were optimized. All the bacteria showed maximum naphthalene degrading ability at pH 7.0. Bacillus exhibited highest naphthalene degrading activity at 330 C whereas Micrococcus and Pseudomonas at 310 C. Dr. P.

Alteration of growth and differentiation factors response by Kirsten and Harvey sarcoma viruses in the IL-3-dependent murine hematopoietic cell line 32D C13(G)
No full text32D C13(G) is an interleukin 3(IL3)-dependent nontumorigenic murine hematopoietic cell line which undergoes terminal differentiation into granulocytes when exposed to granulocytic colony stimulating factor (G-CSF). Infections of 32D C13(G) cells with either Kirsten rat sarcoma virus or Balb murine sarcoma virus, both containing a v-ras oncogene, generates clones that can permanently grow in G-CSF without differentiation. 32D-Ki-ras cells show a heterogeneous morphology ranging from the promyelocytic to the myelocytic stage of differentiation, and express high levels of both myeloperoxidase (MPO) and lactoferrin (LF) mRNA. 32D-Ha-ras cells show a more immature phenotype and express MPO but no LF mRNA. The apparent differentiation block of both 32D Ki-ras and 32D Ha ras can be reversed by treatment with the chemical inducers retinoic acid, sodium butyrate or dimethylsulphoxide, which leads to terminal differentiation into granulocytes. When 32D-Ki-ras and 32D-Ha-ras cells are cultured in medium containing IL-3 they become adherent and express some monocyte-macrophage markers. Upon prolonged exposure to IL3, 32D-Ki-ras, but not 32D-Ha-ras, resume suspension growth. Both 32D-Ki-ras and 32D-Ha-ras rapidly die if grown in chemically defined medium in the absence of any growth factor and are non-tumorigenic in immunosuppressed mice. These findings indicate that ras activation may interfere with the normal response to growth and differentiation factors in cells of the granulocytic lineage. These alterations may represent a critical, although non-sufficient, step in leukemogenesis

Ancestral Consanguinity and Mortality Among Three Endogamous Populations of Chittoor District, Andhra Pradesh, India
No full textConsanguineous marriages have been practiced around the globe by many societies from time immemorial, particularly in South India. Consanguineous marriages play a major role in the health of a population, and diseases leading to mortality of the progeny are a consequence of detrimental recessive genes. To evaluate the effects of ancestral consanguinity on mortality in relation to consanguineous marriage, we have ascertained data from 1,500 women belonging to three endogamous communities (Akuthota Reddy, Odde, and Madiga) of Chittoor District, Andhra Pradesh, India. There were 500 women from each community. For each marriage we drew a family pedigree, extended upward to two earlier generations on either side of the spouses to determine the prevalence and pattern of consanguinity, with detailed information on fertility and mortality. We observed a significant difference in the mortality rates between consanguineous and nonconsanguineous marriages when all the marriages of the women, women’s parents, and (women’s) husband’s parents were considered in all three communities. In inbreeding, the offspring of earlier generations might have passed on deleterious genes to later generations (under unfavorable conditions), which resulted in a negative aspect of reproduction (among the offspring of the present couple)

Phys. 66, 5259 (1977).Author Institution:The collision-induced fundamental band of in the pure gas at 77, 196 and 298 K was recorded for a number of gas densities up to 60 amagat with two 2 m absorption cells. The contributions to the intensity of the band from the short-range overlap and long-range quadrupolar interactions were separated by carrying out an analysis of the absorption profiles. For the molecular pairs, the overlap parameters, and , which represent, respectively, the magnitude and range of the induced-overlap dipole moment, and , the induced dipole moment at the Lennard-Jones intermolecular diameter were determined. Finally these parameters of were compared with those of and HD - HD, determined earlier in our $laboratory.^{1,2}
