Evolutionary Genetics And Genetic Variation Of Haplodiploids And X-Linked Genes, Philip W. Hedrick, Joel D. Parker
Evolutionary Genetics And Genetic Variation Of Haplodiploids And X-Linked Genes, Philip W. Hedrick, Joel D. Parker
Joel D Parker
The evolutionary genetics of haplodiploids and X-linked genes share many features and are different from diploid (autosomal) genes in many respects. For example, the conditions for a stable polymorphism, the amount of genetic load, and the effective population size are all expected to be quite different between haplodiploids or X-linked genes and diploids. From experimental data, the genetic load for X-linked genes is much less than autosomal genes and appears less for haplodiploids than for diploids. The observed amount of molecular variation for haplodiploids is much less than that for diploids, even more so than predicted from the differences in …

The Brain As A Symbol-Processing Machine., Armando F. Rocha
Armando F Rocha
The knowledge accumulated about the biochemistry of the synapsis in the last decades completely changes the notion of brain processing founded exclusively over an electrical mechanism, toward that supported by a complex chemical message exchange occurring both locally, at the synaptic site, as well as at other localities, depending on the solubility of the involved chemical substances in the extracellular compartment. These biochemical transactions support a rich symbolic processing of the information both encoded by the genes and provided by actual data collected from the surrounding environment, by means of either special molecular or cellular receptor systems. In this processing, …
Hadhramaut And The Hadhrami Diaspora: Problems In Theoretical History, Syed Farid Alatas
Hadhramaut And The Hadhrami Diaspora: Problems In Theoretical History, Syed Farid Alatas
farid alatas
If we understand history as a field constituted by a type of research and inquiry that concerns itself with human action in the past and is based on the interpretation of evidence, regardless of whether positivist or interpretive methods are used, then it can be said that historical works on Hadhramaut and its diaspora have been written. These works can be divided in broad terms into the two general categories of Arab and Western historiography. Nevertheless, in both cases, owing to certain theoret- ical problems that have beset these works, little progress has been made in the advancement of Hadhrami …

Isolation Of A Mannose-Binding And Ige- And Igm-Reactive Lectin From The Seeds Of Artocarpus Integer, Onn Haji Hashim
Isolation Of A Mannose-Binding And Ige- And Igm-Reactive Lectin From The Seeds Of Artocarpus Integer, Onn Haji Hashim
Onn Haji Hashim
A mannose-binding lectin, termed champedak lectin-M, was isolated from an extract of the crude seeds of champedak (Artocarpus integer). On gel filtration chromatography, the lectin eluted in a single peak at elution volumes corresponding to 64 kDa, SDS-PAGE showed the mannose-binding lectin to be composed of 16.8 kDa polypeptides with some of the polypeptides being disulphide-linked to give dimers. When tested with all isotypes of immunoglobulins, champedak lectin-M demonstrated a selective strong interaction with human IgE and IgM, and a weak interaction with IgA2, The binding interactions of lectin-M were metal ion independent. The lectin was also shown to interact …
