Mafic-ultramafic rocks of Archaean age constitute a significant component of the Eastern Indian Craton. These occur in two different modes. In the eastern belt these occur as a long, linear enclave within the Singhbhum granite and the primary banding in them is subvertical. In the more extensive western belt along the periphery of the Singhbhum granite, the disposition of the primary banding is subhorizontal.

1. The fatty liver of newly-hatched pigeons is caused by an accumulation of sterol esters (STE) amounting to 620 mg/g total lipids of which 80% was sterol oleate. Triglycerides (TG) accounted for only 20 mg/g of total lipids.2. After hatching, the relative amount of STE in the liver tissue decreased considerably while that of TG increased. The proportion of phospholipids (PHL) remained essentially constant.3. The fatty acid composition of the liver lipids changed significantly, but specifically for each individual class during postnatal growth. Striking differences were the higher values of long-chain polyunsaturated acids (20 :4 ω6, 22 :4 ω6 and 22: 6 ω3) in PHL, TG and free fatty acids (FFA) and the higher proportion of oleic acid in the STE at hatching compared with those at older ages.4. The predominant alterations in the relative composition of the liver lipids (lipid classes and fatty acids) occurred in the first week after hatching and may be accounted for by the decreasing yolk utilisation and adaptation to ingested food. The change within the diet itself from cropmilk to grain (starting around the 4th day) influenced the development of the lipid and fatty acid content only in a minor way.5. The large weight decrease of the pigeon liver after the 19th day was accompanied by a decrease in absolute PHL content while TG stores were unaltered.

The fatty acid pattern of the triglycerides (TG) and phospholipids (PHL) from liver, adipose tissue and crop of the pigeon was studied at various stages of posthatching development to determine the influence of the changing diet. In each tissue and at all ages PHL contained more stearic and polyenoic but less monoenoic acids than the corresponding TG. Especially in the young squabs the acid composition of the liver (TG as well as PHL) was different from that of the adipose tissue and the crop. In these last tissues, only small variations were noticed during growth, whereas in the liver the acid pattern changed drastically and specifically for each lipid fraction, mainly in the 1st week after hatching. During the period of only cropmilk feeding (0–4 days) the TG from adipose tissue and crop resembled more the acid pattern of the diet than that of the liver TG, suggesting that in this period these tissues derive their acids for TG synthesis mostly from exogenous sources rather than from the liver. The subsequent change from cropmilk to grain diet was not clearly reflected in the acid content of the examined tissues probably as a result of an enhanced de novo synthesis. The acid distribution in the PHL of the various tissues was at all ages very different from that of the corresponding diets and their alterations, characteristic for each tissue, may therefore be correlated more with age than with dietary conditions.

ABSTRACTThe U.S. Culture Collection Network held a meeting to share information about how culture collections are responding to the requirements of the recently enacted Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity (CBD). The meeting included representatives of many culture collections and other biological collections, the U.S. Department of State, U.S. Department of Agriculture, Secretariat of the CBD, interested scientific societies, and collection groups, including Scientific Collections International and the Global Genome Biodiversity Network. The participants learned about the policies of the United States and other countries regarding access to genetic resources, the definition of genetic resources, and the status of historical materials and genetic sequence information. Key topics included what constitutes access and how the CBD Access and Benefit-Sharing Clearing-House can help guide researchers through the process of obtaining Prior Informed Consent on Mutually Agreed Terms. U.S. scientists and their international collaborators are required to follow the regulations of other countries when working with microbes originally isolated outside the United States, and the local regulations required by the Nagoya Protocol vary by the country of origin of the genetic resource. Managers of diverse living collections in the United States described their holdings and their efforts to provide access to genetic resources. This meeting laid the foundation for cooperation in establishing a set of standard operating procedures for U.S. and international culture collections in response to the Nagoya Protocol.
