Since DTs tend to infiltrate and compress adjacent structures, the location of DTs is one of the most crucial factors for determining the severity of the disease. Furthermore, DTs can further complicate the clinical course of patients when the growth is remarkably rapid, especially for DTs occurring in anatomically critical compartments, including the thoracic cavity. The authors report a case of a 7. Imaging studies revealed a 1. The mass infiltrated into the chest wall and also displaced the mediastinum contralaterally. Interestingly, the tumor had an extremely rapid doubling time of 3. En bloc resection of the tumor was performed as a curative as well as a diagnostic measure. Histopathologic examination showed spindle cells with low cellularity and high collagen deposition in the stroma. Immunohistochemical staining was positive for nuclear . Based on these pathologic findings, the mass was diagnosed as DT. After surgery, there has been no evidence of recurrence of disease in the patient. This patient presents a mediastinal DT with extremely rapidgrowth. Notably, the doubling time of DT in our case was the shortest among reported cases of DT. Our experience also highlights the benefits of early interventional strategy, especially for rapidly growing DTs in the thoracic cavity. PMID: 2. 67. 17. 38. Cryptococcus neoformans Thermotolerance to Avian Body Temperature Is Sufficient For Extracellular Growth But Not Intracellular Survival In Macrophages. Pub. Med Central. Johnston, Simon A.; Voelz, Kerstin; May, Robin C. Cryptococcus neoformans is a fatal fungal pathogen of humans that efficiently parasitises macrophages. Birds can be colonised by cryptococci and can transmit cryptococcosis to humans via inhalation of inoculated bird excreta. However, colonisation of birds appears to occur in the absence of symptomatic infection. Here, using a pure population of primary bird macrophages, we demonstrate a mechanism for this relationship. We find that bird macrophages are able to suppress the growth of cryptococci seen in mammalian cells despite C. A small subset of cryptococci are able to adapt to the inhibitory intracellular environment of bird macrophages, exhibiting a large cell phenotype that rescues growth suppression. Thus, restriction of intracellular growth combined with survival at bird body temperature explains the ability of birds to efficiently spread C. PMID: 2. 68. 83. 08. Neuregulin- 1 Administration Protocols Sufficient for Stimulating Cardiac Regeneration in Young Mice Do Not Induce Somatic, Organ, or Neoplastic Growth. Pub. Med Central. Ganapathy, Balakrishnan; Nandhagopal, Nikitha; Polizzotti, Brian D.; Bennett, David; Asan, Alparslan; Wu, Yijen; K. Our results suggested the use of r. NRG1 to treat pediatric patients with heart failure. However, administration in this age group may stimulate growth outside of the heart. Methods NRG1 and Erb. B receptor expression was determined by RT- PCR. Mice that received protocols of recombinant neuregulin. Somatic growth was quantified by weighing. Organ growth was quantified by MRI and by weighing. Neoplastic growth was examined by MRI, visual inspection, and histopathological analyses. Phospho- ERK1/2 and S6 kinase were analyzed with Western blot and ELISA, respectively. Results Lung, spleen, liver, kidney, brain, and breast gland exhibited variable expression of the NRG1 receptors Erb. B2, Erb. B3, Erb. B4, and NRG1. Body weight and tibia length were not altered in mice receiving r. NRG1. MRI showed that administration of r. NRG1 did not alter the volume of the lungs, liver, kidneys, brain, or spinal cord. Administration of r. NRG1 did not alter the weight of the lungs, spleen, liver, kidneys, or brain. MRI, visual inspection, and histopathological analyses showed no neoplastic growth. Follow- up for 6 months showed no alteration of somatic or organ growth. Conclusions Administration protocols of r.

Design A 3. 8- year prospective longitudinal study of a representative birth cohort. Setting The Dunedin Multidisciplinary Health and Development Study, Dunedin, New Zealand. Participants One thousand thirty- seven male and female study members. Main Exposures We assessed genetic risk with a multilocus genetic risk score. The genetic risk score was composed of single- nucleotide polymorphisms identified in genome- wide association studies of obesity- related phenotypes. We assessed family history from parent body mass index data collected when study members were 1. Main Outcome Measures Body mass index growth curves, developmental phenotypes of obesity, and adult obesity outcomes were defined from anthropometric assessments at birth and at 1. Results Individuals with higher genetic risk scores were more likely to be chronically obese in adulthood. Genetic risk first manifested as rapidgrowth during early childhood. Genetic risk was unrelated to birth weight. After birth, children at higher genetic risk gained weight more rapidly and reached adiposity rebound earlier and at a higher body mass index. In turn, these developmental phenotypes predicted adult obesity, mediating about half the genetic effect on adult obesity risk. Genetic associations with growth and obesity risk were independent of family history, indicating that the genetic risk score could provide novel information to clinicians. Conclusions Genetic variation linked with obesity risk operates, in part, through accelerating growth in the early childhood years after birth. Etiological research and prevention strategies should target early childhood to address the obesity epidemic. PMID: 2. 26. 65. 02. The Spatial Distribution of the Exocyst and Actin Cortical Patches Is Sufficient To Organize Hyphal Tip Growth. Pub. Med Central. Caballero- Lima, David; Kaneva, Iliyana N.; Watton, Simon P. In the hyphal tip of Candida albicans we have made detailed quantitative measurements of (i) exocyst components, (ii) Rho. We use the resulting data to construct and test a quantitative 3- dimensional model of fungal hyphal growth based on the proposition that vesicles fuse with the hyphal tip at a rate determined by the local density of exocyst components. Enzymes such as (1,3)- . The model successfully predicts the shape and dimensions of the hyphae, provided that endocytosis acts to remove cell wall- synthesizing enzymes at the subapical bands of actin patches. Moreover, a key prediction of the model is that the distribution of the synthase is substantially broader than the area occupied by the exocyst. This prediction is borne out by our quantitative measurements. Thus, although the model highlights detailed issues that require further investigation, in general terms the pattern of tip growth of fungal hyphae can be satisfactorily explained by a simple but quantitative model rooted within the known molecular processes of polarized growth. Moreover, the methodology can be readily adapted to model other forms of polarized growth, such as that which occurs in plant pollen tubes. PMID: 2. 36. 66. 62. Rapid population growth and environmental degradation: ultimate versus proximate factors. Pub. Med. Shaw, R P1. This philosophical review of 2 arguments about responsibility for and solutions to environmental degradation concludes that both sides are correct: the ultimate and the proximal causes. Ultimate causes of pollution are defined as the technology responsible for a given type of pollution, such as burning fossil fuel; proximate causes are defined as situation- specific factors confounding the problem, such as population density or rate of growth. Commoner and others argue that developed countries with low or negative population growth rates are responsible for 8. Distortionary policies also contribute; examples are agricultural trade protection, land mismanagement, urban bias in expenditures, and institutional rigidity., Poor nations are responsible for very little pollution because poverty allows little waste or expenditures for polluting, synthetic technologies. The proximal causes of pollution include numbers and rate of growth of populations responsible for the pollution. Since change in the ultimate cause of pollution remains out of reach, altering the numbers of polluters can make a difference. Predictions are made for proportions of the world's total waste production, assuming current 1. If developing countries grow at current rates and become more wealthy, they will be emitting half the world's waste by 2. ON the other hand, unsustainable population growth goes along with inadequate investment in human capital: education, health, employment, infrastructure. The solution is to improve farming technologies in the 1. Changes in Colonic Bile Acid Composition following Fecal Microbiota Transplantation Are Sufficient to Control Clostridium difficile Germination and Growth. Pub. Med Central. Weingarden, Alexa R.; Dosa, Peter I.; De. Winter, Erin; Steer, Clifford J.; Shaughnessy, Megan K.; Johnson, James R.; Khoruts, Alexander; Sadowsky, Michael J. Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent Clostridium difficile infection (R- CDI), but its mechanisms remain poorly understood. Emerging evidence suggests that gut bile acids have significant influence on the physiology of C. We analyzed spore germination of 1. C. Bile acids at concentrations found in patients. However, bile acids at concentrations found in patients after FMT did not induce germination and inhibited vegetative growth of all C.
