Eukaryotes are a very diverse group, and their cell structures are equally diverse. Many have cell walls; many do not. Many have chloroplasts, derived from primary, secondary, or even tertiary endosymbiosis; and many do not. Some groups have unique structures, such as the cyanelles of the glaucophytes , the haptonema of the haptophytes , or the ejectisomes of the cryptomonads . Other structures, such as pseudopods , are found in various eukaryote groups in different forms, such as the lobose amoebozoans or the reticulose foraminiferans .
There is no scientific evidence that HCG is effective in the treatment of obesity. The meta-analysis found insufficient evidence supporting the claims that HCG is effective in altering fat-distribution, hunger reduction, or in inducing a feeling of well-being. The authors stated “…the use of HCG should be regarded as an inappropriate therapy for weight reduction…” In the authors opinion, “Pharmacists and physicians should be alert on the use of HCG for Simeons therapy. The results of this meta-analysis support a firm standpoint against this improper indication. Restraints on physicians practicing this therapy can be based on our findings.”
