Observations on the pancreas of the marine lizard fish Saurida tumbil (Bloch)

The pancreas in the marine lizard fish Saurida tumbil (Bloch) encircles the pyloric region of the gastro-intestinal canal. The islets of Langerhans are ovoidal usually with a central cluster of β cells and the α cells in the periphery. In contrast to the β cells, the α cells have larger nuclei. Saurida tumbil is heavily parasitized by cestodes, nematodes and trematodes which infect the pancreas displacing or replacing much of the tissue.     

Deoxyribonucleic acid metabolism and nuclear division during spore germination in Fusarium oxysporum.

Ungerminated microconidia of Fusarium oxysporum have a mean cell DNA content of 0-134 times 10--12 g/cell with a guanine-plus-cytosine composition (%GC) of 50-75%. During germination, the first dry weight increase of the spore population was defected after 3 h incubation and the first germ tube appeared after 4 h. The total DNA of the culture sharply increased after 5 h, followed by a pause at 6 h. At this time the DNA content per nucleus was maximal and the first nuclear divisions were detected. auses in the rise of total DNA of the culture and in the [14C]adenine incorporation pattern suggest that there is partial synchrony in DNA synthesis at the beginning of incubation. This is also supported by the fact that until 8 h, only hyphae with 1, 2 and 4 nucleic were observed. [14C]adenine incorporation into DNA averaged 2-68% of the total taken up in 10 h incubation.     

Chlorolepiota indica sp. nov.—A new species from India

A new species Chlorolepiota indica is reported from Patiala in Punjab, India. The fungus is characterized by convex brown pileus covered by concentrically arranged brown scales with yellow tinge around the umbo. The stipe of the fruiting body is cream to pale yellow, pinkish to reddish brown near the pileus, and yellowish to dark grey brown towards the base.     

C-Phycocyanin-a novel protein from Spirulina platensis- In vivo toxicity,antioxidant and immunomodulatory studies

A pigment-protein highly dominant in Spirulina is known as C-Phycocyanin. Earlier, in vitro studies has shown that C-phycocyanin is having many biological activities like antioxidant and anti-inflammatory activities, antiplatelet, hepatoprotective, and cholesterol-lowering properties. Interestingly, there are scanty in vivo experimental findings on the immunomodulatory and antioxidant effects of C-phycocyanin. This work is aimed at in vivo evaluation of the effects of C-phycocyanin on immunomodulation and antioxidant potential in Balb/c mice. Our results of in vivo toxicity, immunomodulatory and antioxidant effects of C-Phycocyanin suggests that C-phycocyanin is very safe for consumption and having substantial antioxidant potential and also possess immunomodulatory activities in Balb/c mice in a dosage dependent manner. C-phycocyanin doesn’t cause acute and subacute toxicity in the animal model (male, Balb/c mice) studied. We have reported that C-phycocyanin exhibited in vivo immunomodulation performance in this animal model.

TORC1 and TORC2 work together to regulate ribosomal protein S6 phosphorylation in Saccharomyces cerevisiae

Nutrient-sensitive phosphorylation of the S6 protein of the 40S subunit of the eukaryote ribosome is highly conserved. However, despite four decades of research, the functional consequences of this modification remain unknown. Revisiting this enigma in Saccharomyces cerevisiae, we found that the regulation of Rps6 phosphorylation on Ser-232 and Ser-233 is mediated by both TOR complex 1 (TORC1) and TORC2. TORC1 regulates phosphorylation of both sites via the poorly characterized AGC-family kinase Ypk3 and the PP1 phosphatase Glc7, whereas TORC2 regulates phosphorylation of only the N-terminal phosphosite via Ypk1. Cells expressing a nonphosphorylatable variant of Rps6 display a reduced growth rate and a 40S biogenesis defect, but these phenotypes are not observed in cells in which Rps6 kinase activity is compromised. Furthermore, using polysome profiling and ribosome profiling, we failed to uncover a role of Rps6 phosphorylation in either global translation or translation of individual mRNAs. Taking the results together, this work depicts the signaling cascades orchestrating Rps6 phosphorylation in budding yeast, challenges the notion that Rps6 phosphorylation plays a role in translation, and demonstrates that observations made with Rps6 knock-ins must be interpreted cautiously.
