Study of Several Soil Properties which Managed Conventionally and by Organic Systems in Naga Timbul Village, Bonatua Lunasi Sub-District of Toba Samosir District```

The current agricultural system is generally carried out conventionally depending on the use of chemical fertilizers. But long-term use will have a negative impact because it can acidify the soil. This study's aim was to determine several physical and chemical of soil properties managed by conventional agriculture and organic systems in Naga Timbul Village, Bonatua Subdistrict, Toba Samosir District. The method used was purposive sampling which was carried out compositely on 4 sample points by the zigzag method, 2 points on conventional agricultural land, and 2 points on organic agricultural land, at a depth of 0-20 cm and 20-40 cm. The research started from June to November 2017. The parameters observed were soil physical properties (bulk density, total pore space, and water content) and soil chemical properties (soil pH, organic C, P-available, and P-total). The results showed that the newly managed organic farming system for 3 years had a bulk density value (1.37 g / cm3) 9.67% lower compared to conventional farming systems (1.52 g / cm3); total pore space (48.34%) 11.45% higher compared to conventional farming systems (42.81%); and water content (45.44%) 40.53% higher than conventional farming systems (27.02%). The pH value around (5.13) 3.71% higher compared to conventional agricultural land (4.94); C-Organic (0.55%) 31.25% lower compared to conventional farming systems (0.80%); P-available (25.83 ppm) 28.62% lower compared to the conventional system (36.19 ppm); and the P total value (135.09%) 44.44% lower compared to conventional farming systems (243.15%)

Urinary proteomic profiling in severe obesity and obstructive sleep apnoea with CPAP treatment.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in obesity and is associated with cardiovascular and metabolic complications. Continuous positive airway pressure (CPAP) in OSA may lead to physiological changes reflected in the urinary proteome. The aim of this study was to characterise the urinary proteome in severely obese adult subjects with OSA who were receiving CPAP compared with severely obese subjects without OSA. METHODS: Severely obese subjects with and without OSA were recruited. Subjects with OSA were receiving CPAP. Body composition and blood pressure measurements were recorded. Urinary samples were analysed by Capillary Electrophoresis-Mass Spectrometry (CE-MS). RESULTS: Twenty-seven subjects with OSA-on-CPAP (age 49±7years, BMI 43±7 kg/m(2)) and 25 controls without OSA (age 52±9years, BMI 39±4 kg/m(2)) were studied. Age and BMI were not significantly different between groups. Mean CPAP use for OSA patients was 14.5±1.0 months. Metabolic syndrome was present in 14(52%) of those with OSA compared with 6(24%) of controls (p=0.039). A urinary proteome comprising 15 peptides was identified showing differential expression between the groups (p<0.01). Although correction for multiple testing did not reach significance, sequences were determined for 8 peptides demonstrating origins from collagens, fibrinogen beta chain and T-cadherin that may be associated with underlying cardiovascular disease mechanisms in OSA. CONCLUSIONS: The urinary proteome is compared in OSA with CPAP and without OSA in severe obesity. The effects of CPAP on OSA may lead to changes in the urinary peptides but further research work is needed to investigate the potential role for urinary proteomics in characterising urinary peptide profiles in OSA

Psychometric and biomedical outcomes of glycated haemoglobin target-setting in adults with type 1 and type 2 diabetes:Protocol for a mixed-methods parallel-group randomised feasibility study

BACKGROUND: The disease burden of diabetes can have wide-ranging implications on patients’ psychological well-being and health-related quality of life. Glycated haemoglobin targets are commonly used to guide patient management in diabetes to reduce the future risk of developing diabetes complications, but little is known of the psychological impact of glycated haemoglobin target-setting. This protocol describes a study to determine the feasibility of evaluating psychological outcomes when setting explicit glycated haemoglobin targets in people with diabetes. METHODS: This single-centre randomised feasibility study will follow a mixed-methods approach across four sub-studies. In sub-study A, eligible adults (aged 18 and over) with type 1 or type 2 diabetes will complete baseline validated psychometric questionnaires evaluating health-related quality of life (EuroQoL-5D-5L), diabetes-related distress (Problem Areas In Diabetes), self-care (Summary of Diabetes Self-Care Activities), well-being (Well-Being Quetionnaire-12) and diabetes-related psychosocial self-efficacy (Diabetes Empowerment Scale-Long Form). Participants will be randomised to receive explicit glycated haemoglobin intervention targets 5mmol/mol above or below current glycated haemoglobin readings. Rates of eligibility, recruitment, retention and questionnaire response rate will be measured. Psychometric outcomes will be re-evaluated 3-months post-intervention. Sub-studies B and C will use qualitative semi-structured interviews to evaluate experiences, views and opinions of diabetes patients and healthcare professionals in relation to the acceptability of study processes, the use of glycated haemoglobin targets, the impact of diabetes on psychological well-being and, in sub-study D, barriers to participation in diabetes research. DISCUSSION: This mixed-methods study aims to provide a novel insight into the psychological implications of glycated haemoglobin target-setting for people with diabetes in secondary care, alongside testing the feasibility of undertaking a larger project of this nature. TRIAL REGISTRATION: The study is registered with the ISRCTN (registration number: 12461724; date registered: 11(th) June 2021). Protocol version: 2.0.5, 26(th) February 2021

Diffusion MR Characteristics Following Concurrent Radiochemotherapy Predicts Progression-Free and Overall Survival in Newly Diagnosed Glioblastoma.

The standard of care for newly diagnosed glioblastoma (GBM) is surgery, then radiotherapy (RT) with concurrent temozolomide (TMZ), followed by adjuvant TMZ. We hypothesized patients with low diffusivity measured using apparent diffusion coefficient (ADC) histogram analysis evaluated after RT+TMZ, prior to adjuvant TMZ, would have a significantly shorter progression-free (PFS) and overall survival (OS). To test this hypothesis we evaluated 120 patients with newly diagnosed GBM receiving RT+TMZ followed by adjuvant TMZ. MRI was performed after completion of RT+TMZ, prior to initiation of adjuvant TMZ. A double Gaussian mixed model was used to describe the ADC histograms within the enhancing tumor, where ADCL and ADCH were defined as the mean ADC value of the lower and higher Gaussian distribution, respectively. An ADCL value of 1.0 um2/ms and ADCH value of 1.6 um2/ms were used to stratify patients into high and low risk categories. Results suggest patients with low ADCL had significantly shorter PFS (Cox Hazard Ratio = 0.12, P = 0.0006). OS was significantly shorter with low ADCL tumors, showing a median OS of 407 vs. 644 days (Cox Hazard Ratio = 0.31, P = 0.047). ADCH was not predictive of PFS or OS when accounting for age and ADCL. In summary, newly diagnosed glioblastoma patients with low ADCL after completion of RT+TMZ are likely to progress and die earlier than patients with higher ADCL. Results suggest ADC histogram analysis may be useful for patient risk stratification following completion of RT+TMZ

Astaxanthin is responsible for the pink plumage flush of Franklins and Ring-billed gulls

ABSTRACT. Carotenoid pigments produce the red, orange, and yellow plumage of many birds. Carotenoidcontaining feathers are typically rich in color and displayed by all adult members of the species. In many gulls and terns, however, an unusual light pink coloring (or flush) to the normally white plumage can be found in highly variable proportions within and across populations. The carotenoid basis of plumage flush was determined in an Elegant Tern (Sterna elegans; Hudon and Brush 1990), but it is not clear if all larids use this same mechanism for pink plumage coloration. We examined the carotenoid content of pink feathers in Franklin&apos;s (Larus pipixcan) and Ring-billed (Larus delawarensis) gulls and found that a single carotenoid-astaxanthin-was present. Astaxanthin was primarily responsible for the flush in Elegant Terns as well, but was accompanied by other carotenoids (e.g., canthaxanthin and zeaxanthin), as is typical of most astaxanthin-containing bird feathers. In both gull and tern species, carotenoids were contained within feathers and did not occur on the plumage surface in preen oil, as some have previously speculated. We hypothesize that some gulls turn pink because they acquire unusually high amounts of astaxanthin in their diets at the time of feather growth. It is tempting to link the increase in sightings of pink Ringbilled Gulls since the late 1990s with the introduction of pure, synthetic astaxanthin to the diets of hatchery-raised salmon. SINOPSIS. Astaxantina, responsible del plumaje Rosado en Larus pixpican y Larus delawarensis Los pigmentos carotenoides son los responsables de la coloración roja, anaranjada y amarilla en el plumaje de aves. Plumas que contienen carotenoides, generalmente son ricas en color y son mostradas en variados patrones de conducta por los adultos con dicha coloración. No obstante, en muchas gaviotas se puede observar una coloración rosada, en vez del típico plumaje blanco y su proporción puede ser variable en una o entre poblaciones. La presencia de carotenoides, y plumaje rosado, fue documentado en Sterna elegans, pero no quedo claro, si el mismo tipo de mecanismo aplica a otros laridos. Examinamos el contenido carotenoides en plumas rosadas de las gaviotas, Larus pixpican y L. delawarensis, y encontramos que la presencia de astaxantina. Este mismo carotenoide fue el principal responsable de la coloración rosada en Sterna elegans, sin embargo estuvo acompañado de otros carotenoides (ej. cantaxantina y seazantina). En las diferentes gaviotas estudiadas se encontró que los carotenoides se encontraban dentro de la pluma y no presentes en la superficie de estas o en el aceite de la glándula uropigial, como se había previamente especulado. Nuestra hipótesis es que algunas gaviotas adquieren un plumaje rosado a consecuencia de la dieta ingerida durante el periodo de crecimiento de las plumas. Es tentador tratar de atar el color rosado en gaviotas como L. delawarensis a partir del 1990 con la introducción de astaxantina sintética en la dieta de salmones criados en cautiverio

Matériaux polymères pour la création de guides optiques

5 pagesNational audienceUn des objectifs de travail au laboratoire Foton est l'amélioration du confinement de la lumière dans les microstructures polymères, de par leurs propriétés optiques (indices de réfraction optimisés, transparence à la longueur d'onde choisie) et chimiques (compatibilité des matériaux de cœur et de gaine, stabilité dans le temps), ainsi que par la réduction des pertes intrinsèques et extrinsèques des guides. Pour cela, la détermination des propriétés physico-chimiques des polymères utilisés lors de la création d'un guide optique et l'optimisation des interfaces mises en jeu sont deux directions de travail privilégiées, sachant que les structures polymères sont réalisées en photolithographie conventionnelle par masquage dans l'UV à 365 nm sur un substrat de silicium, suivi d'une gravure RIE
