X-ray dynamical diffraction analogues of the integer and fractional Talbot effects
The X-ray integer and fractional Talbot effect is studied under two-wave dynamical diffraction conditions in a perfect crystal, for the symmetrical Laue case of diffraction. The fractional dynamical diffraction Talbot effect is studied for the first time. A theory of the dynamical diffraction integer and fractional Talbot effect is given, introducing the dynamical diffraction comb function. An expression for the dynamical diffraction polarization-sensitive Talbot distance is established. At the rational multiple depths of the Talbot depth the wavefield amplitude for each dispersion branch is a coherent sum of the initial distributions, shifted by rational multiples of the object period and having its own phases. The simulated dynamical diffraction Talbot carpet for the Ronchi grating is presented.
Conclusions: Results of the present study support the interpersonal theory of suicide, which suggests that self-reported thwarted belongingness can foster WD. Clinical implications: Clinicians should consider social dissatisfaction and withdrawal as risk factors for WD and design interventions that foster social skills or meaningful connections.

CONCLUSIONS: we found an association between SIBO and allergic disease, especially allergic rhinitis, cow's milk protein allergy and asthma. Thus, SIBO should be ruled out in pediatric patients with CAP and allergic disease. PMID: 31617366 [PubMed - as supplied by publisher]
CONCLUSIONS: this meta-analysis supported the association of AF with increased risk of GERD. PMID: 31617365 [PubMed - as supplied by publisher]
CONCLUSION: these data support the hypothesis that the hepatitis C virus may worsen quality of life in asymptomatic patients. PMID: 31617364 [PubMed - as supplied by publisher]
We report a case of a 67-year-old female presented with hematemesis eventually diagnosed with duodenal mucormycosis, while radiology characteristics suggested malignancy. PMID: 31617363 [PubMed - as supplied by publisher]
Authors: Taki S, Maekita T, Sakata M, Fukatsu K, Maeda Y, Iguchi M, Ito H, Kitano M Abstract Continuous duodenal levodopa/carbidopa intestinal gel delivery by a gastrostomy infusion system improves control of Parkinson's disease. The overall complication rates of percutaneous endoscopic gastrojejunostomy were reported to be 41% and 59% for immediate and delayed adverse events, respectively. A 72-year-old woman underwent percutaneous endoscopic gastrojejunostomy using the delivery system noted above. Abdominal pain and vomiting occurred 3 months later. Esophagogastroduodenoscopy showed a longitudinal ulcer extending...
Conclusions: Our study is the first to report that endoscopic therapy of PFCs using LAMS is safe and effective even in a community hospital setting with limited resources and support compared to large academic centers. PMID: 31615198 [PubMed - as supplied by publisher]
