Cropping systems with winter wheat or spring wheat? Root growth, catch crops, nitrogen leaching and baking quality

In organic farming winter wheat is typically grown after good pre-crops, as it pays well for this in terms of yield and quality. However, winter wheat develops slowly during the autumn, and much nitrate may be lost by leaching before spring. System with catch crops followed by spring wheat, or maybe catch crops intercropped with winter wheat could improve the utilization of the pre-crop effects in wheat cropping. In this experiment we studied wheat and catch crop root growth, crop and soil N dynamics, and effects on yield and baking quality in wheat cropping systems with catch crops. The results showed that the com-bination of catch crops and spring wheat was ideal for resource use, but also that winter wheat had a much deeper root system (c. 2.0 m) than spring wheat (c. 1.0 m), and that the N loss from the winter wheat crops therefore became smaller than expected. Intercropping systems with catch crops and winter wheat showed some promising results, but they are also very difficult to manage

Optimal pressure for mimicking clinical breath holding inspiratory CT in the deceased for VPMCT

Introduction Ventilated PMCT (VPMCT) has been reported to provide better quality of pulmonary structures in PMCT in adults and children. However, there are no consensus regarding optimal inflation pressure, and the practical use of VPMCT is still limited by cost of ventilation equipment. Here, we describe a simple and cost-efficient inflation-device for VPMCT and investigate optimal inflation pressure. Aim To elucidate the effect of different ventilation pressures on total lung volume and the volume of ground glass opacities (GGO), air-filled tissue, consolidations, and bronchi in VPMCT. Materials and method A precise inflation device was assembled using standard components: a back-pressure regulator, a water manometer and silicone tubing. Each case had PMCT performed at 0, 10, 20, 30 and 40 cmH2O pressure. Volumes were measured using stereology. Results 14 cases were enrolled in the study. The total lung volume increased significantly by 3612 mL (median) from 0 to 30 cmH2O (p = 0.001). The volume of consolidations was significantly reduced by 455.86 mL (median) between 0 and 30 cmH2O (p = 0.001). A significant reduction of GGO-volume of 133 mL (median) was observed at the pressure interval 30–40 cmH2O (p = 0.031), but not at lower pressures. Conclusion The constructed inflation device allowed precise and reproducible inflation of the lungs in deceased humans. We found a maximum effect of inflation at 30 cmH2O. At further inflation pressure, only the volume of GGOs decreased , but the effect was minor. For mimicking an in vivo breath-hold scan in PMCT we recommend inflation pressure of 30 cmH2O. + Graphical abstrac

Evaluating Vitamin D levels in Rheumatic Heart Disease patients and matched control: A case-control study from Nepal

BackgroundDiagnosis and treatment for Rheumatic Heart Disease (RHD) is inaccessible for many of the 33 million people in low and middle income countries living with this disease. More knowledge about risk factors and pathophysiologic mechanisms involved is needed in order to prevent disease and optimize treatment. This study investigated risk factors in a Nepalese population, with a special focus on Vitamin D deficiency because of its immunomodulatory effects.MethodsNinety-nine patients with confirmed RHD diagnosis and 97 matched, cardiac-healthy controls selected by echocardiography were recruited from hospitals in the Central and Western region of Nepal. Serum 25(OH)D concentrations were assessed using dried blood spots and anthropometric values measured to evaluate nutritional status. Conditional logistic regression analysis was used to define association between vitamin D deficiency and RHD.ResultsThe mean age of RHD patients was 31 years (range 9-70) and for healthy controls 32 years (range 9-65), with a 4:1 female to male ratio. Vitamin D levels were lower than expected in both RDH and controls. RHD patients had lower vitamin D levels than controls with a mean s-25(OH)D concentration of 39 nmol/l (range 8.7-89.4) compared with controls 45 nmol/l (range 14.5-86.7) (p-value = 0.02). People with Vitamin D insufficiency had a higher risk (OR = 2.59; 95% CI: 1.04-6.50) of also having RHD compared to people with Vitamin D concentrations >50 nmol/l. Body mass index was significantly lower in RHD patients (22.6; 95% CI, 21.5-23.2) compared to controls (24.2; 95% CI, 23.3-25.1).ConclusionRHD patients in Nepal have lower Vitamin D levels and overall poor nutritional status compared to the non-RHD controls. Longitudinal studies are needed to explore the causality between RHD and vitamin D level. Future research is also recommended among Nepali general population to confirm the low level of vitamin D as reported in our control group

Wheat baking quality: The effect of catch crop strategies and species

Abstract - In organic farming winter wheat is typically grown after good pre-crops, as it pays well for this in terms of yield and quality. However, winter wheat develops slowly during the autumn, and much nitrate may be lost by leaching before spring. System with catch crops followed by spring wheat, or maybe catch crops intercropped with winter wheat could improve the utilization of the pre-crop effects in wheat crop-ping. In this experiment we studied wheat and catch crop root growth, crop and soil N dynamics, and ef-fects on yield and baking quality in wheat cropping systems with catch crops. The results showed that the combination of catch crops and spring wheat increased the yield and decreased the gluten content, but the bread volume was unaffected by the decrease in gluten Intercropping systems with catch crops and winter wheat showed some promising results, but they are also very difficult to manage. The gluten content of winter wheat with intercropping de-creased, however, as for spring wheat the bread vol-ume was relatively higher for intercropping

The death of a medieval Danish warrior:A case of bone trauma interpretation

Abstract In 1934 a grave was found in the church ruins of the Cistercian Abbey at Øm in central Jutland, Denmark (founded in 1172, demolished 1561 AD). The grave contained the skeletal remains of an individual lying in a supine position with the head towards the west. The anthropological analysis revealed that the remains belonged to a young male, aged 25-30 years at death and approximately 162.7 cm tall. He had 9 perimortem sharp force lesions, five of which were cranial and four were postcranial, indicating he suffered a violent death in a swordfight. This paper presents a detailed analysis and description of the individual lesions and their probable effect on the soft tissue, followed by a suggestion for the most likely order of the blows which caused the lesions, and finally a tentative reconstruction of the battle accompanied by photographs. This case illustrates both that forensic pathology can be very useful when applied to an archaeological case and suggests that the forensic pathologist could benefit from examination of ancient cases when interpreting bone lesions in modern cases.</jats:p
