Astronauts Ochoa and Tanner during egress training. Tannermission specialist, await the beginning of a training session on emergency egress procedures. The human biology of Jim Tanner. Induring his second year of medical training, Jim Tanner expressed the desire to work, ‘where physiology, psychology and sociology meet’. His subsequent exposure to the breadth of an American medical education and to the social and economic environment of post-war Europe distilled his belief in the importance of viewing the human in a broad context.

Following his visits to the American longitudinal growth studies in Jim’s dreams of a broad scientific discipline that incorporated both the biology and ecology of the human were strengthened by an inspirational group of embryonic human biologists with whom he developed ‘… the new Human Biology …’ from the ‘… Physical Anthropology of old…’. The development of human biology over the next 50 years was shaped by the expertise and diversity of that group of visionary scientists who conceived the scientific discipline of ‘human biology’ in which biology, behaviour and social context define the human species.

S 1 August Astronaut Joseph R. Though no extravehicular activity EVA is planned for the mission, at least two astronauts are trained to perform tasks that would require a space walk in the event of failure of remote systems. Tanner works with PCG experiment on middeck. Tannermission specialist, works at area amidst several lockers onboard the Shuttle which support the Protein Crystal Growth PCG experiment.

Cancer incidence and mortality among Swedish leather tanners. METHODS–A cohort of subjects who had been employed for at least one year between and in three Swedish leather tanneries, was established. The cancer incidence and mortality patterns were assessed for the periods and respectively, and cause-specific standardised incidence and mortality ratios SIRs and SMRs were calculated. Excesses, not statistically significant was also found for multiple myelomas SIR 2.

A plausible cause is exposure to chlorophenols, which had occurred in all three plants. The excess of multiple myelomas may also be associated with exposure to chlorophenol. The association between incidence of cancer and specific chemical exposure will be elucidated in a cohort-based case-referent study.

Growth as a mirror: Is endocrine disruption challenging Tanner ‘s concept?

Brachiaria arrecta

Nineteenth century social reformers saw poor child growth as a reflection of terrible environmental conditions of the working class. Later investigators in anthropology and other fields clarified the connections between poor nutrition, disease, psychosocial stress and poor growth. Aim To evaluate the growth as a mirror concept in light of recent studies of endocrine disruption. Papers and Implications Pollution is recognized as a prominent component of the modern environment.

From studies of many pollutants it is clear that some pollutants depress growth while others speed sexual maturation and increase growth, primarily in weight and fatness. While such unwelcome environmental features do not always suppress growth, growth still mirrors the environment in all its complexity and this relationship is key to understanding growth patterns today.

For example, Akwesasne Mohawk adolescents are characterized by high rates of obesity and overweight. Their growth reflects the multiple intersecting influences of psychosocial stress, several pollutant exposures and limited dietary chokes.


Conclusion Although Tanner did not anticipate the myriad influences of pollutants, the growth as a mirror concept continues to have great validity and utility. Tanner and the sport sciences.

Although Tanner was not directly involved in physical education or the sport sciences, several of his papers addressed issues related to research in the area.

To consider the implications of selected papers and research projects for the sport sciences. Several early papers addressed ratio standards, somatotype and total cholesterol, and anthropometric and somatotype changes associated weight training and cessation of training in young adult men.

The papers have, respectively, implications for current studies of allometric scaling, physique and risk factors for cardiovascular and metabolic complications, and responses to training. The survey of athletes at the Rome Olympic Games not only added to the literature but to some extent also set the stage for subsequent surveys of Olympic athletes inand Although not directly involved in the mixed-longitudinal study of Training of Youth Athletes TOYA in several sports, it was conducted in his department.

Results from TOYA indicated no influence of systematic training for sport on growth in height, young adult height and sexual maturation.

Growth at Adolescence was also a fixture in many graduate programs. Though not a sport scientist, Tanner contributed directly and indirectly to the field.

Opilio Tanner Crab Bycatch Phytotoxic substance with allelopathic activity in Brachiaria decumbens. The grass Brachiaria decumbens becomes naturalized and quickly dominant in non-native areas.

It was hypothesized that phytotoxic substances of plants may contribute to the domination and invasion of the plants. However, no potent phytotoxic substance has been reported in B. Therefore, we searched for phytotoxic substances with allelopathic activity in this species. An aqueous methanol extract of B.

These results suggest that this compound may contribute to the allelopathic effect caused by the B. Two other Brachiaria species, B. Therefore, this compound may play an important role in the phytotoxicity of the Brachiaria species. S 10 June Awaiting his helmet, astronaut Joseph R. Obscured in this frame, astronaut Gregory J. Harbaugh was on the other side of the platform, waiting to join Tanner in the spacewalk rehearsal.

Brachiaria Grasses Brachiaria spp. Endophytic and plant-associated bacteria were isolated from plants and rhizoplane soil of naturally grown Brachiaria grasses at International Livestock Research Institute in Nairobi, Kenya. Eighty-four bacterial strains were isolated from leaf tissues, root tissues, and rhizoplane soil on nutrient agar and media.

All bacterial strains were identified to the lowest possible taxonomic unit using 16S rDNA primers and were characterized for the production of Indoleacetic acid, hydrogen cyanide, and ACC deaminase; phosphate solubilization; siderophore production; antifungal properties; and plant biomass production.

The 16S rDNA-based identification grouped these 84 bacterial strains into 3 phyla, 5 classes, 8 orders, 12 families, 16 genera, and 50 unique taxa.

The four most frequently isolated genera were Pseudomonas 23Pantoea 17Acinetobacter 9and Enterobacter 8. The functional characterization of these strains revealed that 41 of 84 strains had a minimum of three plant beneficial properties.

Inoculation of maize seedlings with Acinetobacter spp. The ability of Brachiaria grasses to host genetically diverse bacteria, many of them with multiple plant growth-promoting attributes, might have contributed to high biomass production and adaptation of Brachiaria grasses to drought and arrceta fertility soils.

Brachiaria arrecta (

Thermal alteration of organic matter in recent marine sediments. A series of isoprenoid compounds were isolated from a heat bradhiaria marine sediment from Tanner Basin which were not present in the original sediment. Among the compounds identified were: The significance and possible routes leading to these compounds is discussed. Evidence for biological nitrification inhibition in Brachiaria pastures.

Nitrification, a key process in the global nitrogen cycle that generates nitrate through microbial activity, may enhance losses of fertilizer nitrogen by leaching and denitrification. Certain plants can suppress soil-nitrification by releasing inhibitors from roots, a phenomenon termed biological nitrification inhibition BNI.

Here, we report the discovery of an effective nitrification inhibitor in the root-exudates of the tropical forage grass Brachiaria humidicola Rendle Schweick. Unlike nitrapyrin a synthetic nitrification inhibitorwhich affects only the ammonia monooxygenase AMO pathway, brachialactone appears to block both AMO and hydroxylamine oxidoreductase enzymatic pathways in Nitrosomonas.

Within 3 years of establishment, Brachiaria pastures have suppressed soil nitrifier populations determined as amoA genes; ammonia-oxidizing bacteria and ammonia-oxidizing archaeaalong with nitrification and nitrous oxide emissions. These findings provide direct evidence for the existence and active regulation of a nitrification inhibitor or inhibitors release from tropical pasture root systems. Exploiting the BNI function could become a powerful strategy toward the development of low-nitrifying agronomic systems, benefiting both agriculture and the environment.
