The intracellular distribution of microtubules in pancreatic B-cells was studied morphometrically to elucidate the positive correlation between microtubular content and the rate of insulin release found by biochemical investigations. Rat islet tissue was glucose stimulated under in vivo and in vitro (isolated islets) conditions and tissue samples taken to represent both phases of the phasic insulin response. Electron micrographs (x40 000) of individual B-cells were assembled into montages to obtain complete cell profiles at high magnification.

Abstract Background: Optical coherence tomography angiography (OCTA) is a principally new imaging technique that provide quantitative method to analyze choriocapillaris (CC) flow changes, while assessment of CC in vivo could be valuable in understanding the pathological mechanism of chronic central serous chorioretinopathy (CCSC) and the therapeutic effects of photodynamic therapy (PDT). In this study, we sought to quantify blood flow changes in CC of CCSC patients receiving half-dose PDT using OCTA.Methods: A total of 28 affected eyes and 24 unaffected eyes of 26 CCSC patients receiving half-dose PDT, and 40 eyes of 20 healthy gender- and age-matched subjects were retrospectively enrolled. The proportion of total areas of flow signal voids (FSV, %) in CC level of OCTA was assessed in both eyes of the CCSC patients at baseline and repeated in multiple sections at 1-week, 1-month, 3-month and 6-month intervals after PDT. In addition, CC patterns in response to PDT at early stage and their subsequent morphologic changes were qualitatively documented using OCTA. Results: For affected eyes, significant decrease in FSV was found at 6-m follow-up when compared with that at 1-m follow-up (p=0.036). When compared to normal control eyes, FSV in affected eyes was significantly higher at 1-m, 3-m and 6-m follow-up (p<0.05 for all), while FSV in unaffected eyes was significantly higher at baseline, 1-w, 1-m and 3-m follow-up (p<0.05 for all). Three CC patterns of early response to PDT were identified, including signs of recovery with more even flow signals, transient appearance of worse ischemia and secondary neovascularization within CC level.Conclusion: Abnormal CC flow attenuation remains in completely resolved eyes of CCSC patients treated with half-dose PDT.

Abstract Background and study aims Gastrointestinal neuroendocrine tumors (NET) are generally submucosal in location. Because these tumors are covered with normal mucosa, biopsy is necessary to confirm histological diagnosis before treatment. We explored the diagnostic capabilities of the endocytoscope, which can perform ultra-high magnification in vivo, for staining and diagnosing submucosal tumors in situ.

Microstructural Changes

Central serous chorioretinopathy (CSC) was first described more than 140 years ago. Due to the rapid development in modern imaging methods, better understanding of changes occurring in the retina in CSC is possible. Spectral-domain optical coherence tomography (SDOCT) has increased our ability to study this disease, especially microstructural changes during active phase and after resolution of CSC. SD-OCT enables a highly detailedin vivoevaluation of the individual retinal layers especially external limiting membrane (ELM), the inner and outer segments of photoreceptors and changes in retinal pigment epithelium (RPE), which are the most essential and important in described disease. It allows us better understand pathogenesis of CSC.
