Hemoglobin types of the Caingang Indians of Brazil

We studied the hemoglobin types of 440 individuals (306 unrelated) cytologically and by paper electrophoresis. These included 334 (252 unrelated) putative "full bloods." No abnormal types were found.     

Hemoglobin variant common to Chinese and North American Indians: alpha-2-beta-22 Glu-Ala

An electrophoretically slow hemoglobin variant, in which the structural change involves the replacement of a glutamyl residue by alanyl at position beta-22, was reported in two groups of North American Indians: hemoglobin-G Coushatta, in Alabama-Coushatta Indians in Texas; and hemoglobin-G Saskatoon, in descendants of Santee Indians living in Canada. Hemoglobin-G Hsin-Chu, found in Taiwan in a Chinese from the northern Chinese province of Liaoning, is now shown to have the same structural anomaly.     

Lack of abnormal hemoglobins in Alaskan Eskimos,Indians, and Aleuts

In an examination of the blood of 708 Eskimos, 200 Aleuts, and 44 Indians in Alaska for abnormal types of hemoglobin, only normal hemoglobin A was detected. It may be concluded that abnormal hemoglobins in these races are rare if they occur at all.     

3种禽血抗凝剂效果及其对DNA提取质量的影响

通过3种不同血液抗凝剂对禽血抗凝,提取新鲜的和经冷冻保存一段时间后的抗凝血DNA,运用紫外分光法、凝胶电泳和PCR扩增技术检测提取的DNA样品质量,探讨不同抗凝剂的抗凝效果及其对提取DNA质量的影响。结果表明:3种抗凝血提取的DNA纯度和浓度相近。新鲜抗凝血比冷冻保存一段时间后的抗凝血提取的DNA质量好。ACD抗凝血在冷冻一段时间后出现凝血块,EDTA抗凝血液放置时间过长也影响抗凝效果,但两者在加入裂解液后则可长时间保存。75%乙醇抗凝剂抗凝效果较好,可长时间保存,适合远距离采血。由3种抗凝禽血提取的DNA分子片段完整,能满足常规分子生物学试验研究。     

Cerumen types in Choctaw Indians

Certinen from 432 Choctaw Indians from Mississippi was classified as sticky or dry. The frequency of the autosomal recessive dry type was intermediate between that for Indians of western North America and that for Mayan groups of southern Mexico.     

Cerumen in American Indians: genetic implications of sticky and dry types

Occurrence of sticky and dry cerumen was determined in 483 Indians from various tribes of the United States. The elevated frequencies of the allele for dry cerumen, found in Indians of pure ancestry, support the theory of the mongoloid origin of the American Indian. Potential application of cerumen quality as a marker for genetic and anthropological studies is discussed.     

嘉兴黑猪氟烷基因频率检测初报

随机抽取嘉兴地区部分种猪场嘉兴黑猪血样,通过PCR-RFLP技术进行氟烷基因检测。结果表明,31头嘉兴黑猪基因型均为NN,未出现Nn和nn型基因。该研究为嘉兴黑猪品种资源保护以及合理开发利用提供了理论依据。     

Albumin Naskapi: a new variant of serum albumin

An apparently new Variant of human serum albumin, albumin Naskapi, has been found in high frequency in the Naskapi Indians of Quebec and, in lower frequency,in other North American Indians.The family and population data of the albumin are consistent with its inheritance as a simple autosomal trait Controlled by a gene designated Al Naskapi. This gene is allelic with the gene Al(A) which controls the common albumin.Both homozygotes and heterozygotes have been distinguished. This is the first report of a homozygote for an albumin Variant.     

吉林省水稻国外引种及利用情况

对吉林省品种资源保存和利用现状的研究表明,吉林省选育的品种有国外血缘的占90%以上,具有一半国外血缘的品种占50%以上,说明了国外资源的引入、利用的重要性。同时由于吉林省品种的血缘主要来源于日本品种,遗传背景狭窄,应加大对别国资源的引进和利用力度,扩大遗传背景,提高遗传多样性。     

REACTION OF LYMPHOCYTES WITH PURIFIED PROTEIN DERIVATIVE CONJUGATED WITH FLUORESCEIN

Busy coats from the peripheral bloods of persons known to give a positive reaction to purified protein derivative and of those known to be negative were treated with purified protein derivative conjugated with fluorescein isothiocyanate. Lymphocytes from positive reactors took up the labeled antigen in significantly greater numbers than did those from negative reactors. Leukocytes from newborns showed far less affinity for the antigen than leukocytes from adult negative reactors.     

内蒙古阿拉善盟地区羊硫营养的分析

硫是羊所需的重要矿物质元素之一,缺少与过量都会影响羊的健康状况.本文通过对内蒙古阿拉善盟境内9个嘎查20户人家共计130只羊耳部血液中的矿物质元素硫、锌、铜、钼含量数据的分析,得出该地区羊血液中硫含量明显高于其他地区.     

Fish fertilizer: a native north american practice?

The belief that the use of fish fertilizers originated among North American Indians, and was communicated as such by Squanto to the Plymouth settlers, has achieved the status of folklore and is therefore difficult to challenge. However, examination of the documentary evidence of Squanto's history and of native cultivation practices, and a cultural analysis of the implications of the use of fish fertilizer, have produced complementary lines of evidence. This evidence indicates that widely held beliefs about the "manner of the Indians" should be revised: Squanto's advice at Plymouth is probably best viewed as an interesting example of culture contact, one in which a native "culture-bearer" conveyed a technological idea from one group of Europeans to another.     

浅谈麋鹿茸的药用价值

麋鹿是我国特有鹿科动物,在古代曾广泛分布于长江流域大部分地区,其茸、角、脂、血、肉等均具有药用价值。麋鹿茸是珍惜名贵中药材,在古代医学著作中多有记载,后由于麋鹿在野外灭绝而逐渐失传。麋鹿茸中含有丰富的矿物质、维生素、氨基酸和雌二醇,临床实验证明,麋鹿茸在治疗妇科疾病上有较好疗效。

Hemoglobin types of Macaca irus and Macaca mulatta monkeys

Hemoglobin of 30 Macaca mulatta monkeys and of 15 Macaca irus monkeys consisted of one electrophoretic component similar to human hemoglobin A. Twenty-one M. irus monkeys had two types of hemoglobin. In 20 animals the hemoglobin resembled human hemoglobin AJ, and in one animal it resembled human hemoglobin AI.     

Structural similarities between hemoglobins A and F

A striking similarity has been found between the composition of peptides obtained from tryptic digestion of normal adult hemoglobin (hemoglobin A) and fetal hemoglobin (hemoglobin F).     

Winter dormancy in sea turtles: independent discovery and exploitation in the gulf of california by two local cultures

Documentation is reported for sea turtles overwintering on the sea bottom. Seri Indians have traditionally hunted nonmigrating dormant green turtles (Chelonia mydas) along the bottom of the Infiernillo Channel in the Gulf of California. Mexican fishermen independently discovered dormant turtles during winter 1972-1973, and with new hunting technologies are rapidly decimating these unusual stocks.     

Molar Size Sequences and Fossil Taxonomy

Although relative molar size has been considered a major taxonomic criterion, separating the Australopithecines and some erectus fossils from sapiens man, the Me > Ml, or " fossil" size sequence is found in 33 percent of Ohio whites and Pima Indians, yet is not necessarily the major sequence in the level and below ( 9; 10).

Hemoglobin in a nonleguminous plant, parasponia: possible genetic origin and function in nitrogen fixation

A dimeric hemoglobin was purified from nitrogen-fixing root nodules formed by association of Rhizobium with a nonleguminous plant, Parasponia. The oxygen dissociation rate constant is probably sufficiently high to allow Parasponia hemoglobin to function in a fashion similar to that of leghemoglobin, by oxygen buffering and transport during symbiotic nitrogen fixation. The identification of hemoglobin in a nonlegume raises important questions about the evolution of plant hemoglobin genes.     

Cannibalism. Molecule shows Anasazi ate their enemies

It's official: Scientists say they have definite proof that prehistoric Indians in the southwestern United States not only killed, butchered, and cooked, but actually ate other human beings. The evidence, reported in this week's issue of Nature, takes the form of a dried chunk of human excrement, or coprolite, containing a telltale human protein that could have gotten there only by being ingested.
