We report a case of severe pigmented keratitis with poor prognosis, caused by Cladorrhinum bulbillosum. Antifungal treatment with topical natamycin and fluconazole eye drops and oral tablet fluconazole failed to heal the ulcer and resulted in perforation. The causative fungus, C. bulbillosum, was identified on the basis of its typical microscopic features and 98% sequence homology to ex-type isolate CBS 304.90 (accession no. FM955448). The results of an in vitro antifungal susceptibility test indicated that the isolate was susceptible to natamycin, amphotericin B, fluconazole and itraconazole. The present case is the third case of keratitis and the second case of human keratitis. Compromised immunity due to liver cirrhosis could lead to a failed prognosis even when the fungal isolate is highly susceptible to antifungal treatment.
Endoscopic sclerotherapy (EST) leads to structural and motility changes in the esophagus; the former are thought to be commoner after EST with absolute alcohol (AA), which is a commonly used sclerosant in India as it is cheap and effective. There are no previous studies on changes in esophageal motility after EST with AA. Accordingly, we studied patients with portal hypertension before (n = 24) and after (n = 22) variceal obliteration by EST with AA using a water perfusion esophageal manometry system. Contraction amplitude in the distal esophagus was reduced in the post-EST group compared with the pre-EST group (63.4 +/- 24.9 vs. 18.2 +/- 14.3 mmHg, p < 0.01). Duration of esophageal contraction in both the proximal and distal esophagus became prolonged in the post-EST compared with the pre-EST group (3.3 +/- 0.8 vs. 5.4 +/- 2.6 and 4.3 +/- 1.1 vs. 6.6 +/- 2.3 s, p < 0.001 for both). Lower esophageal sphincter (LES) pressure was reduced in the post-EST compared with the pre-EST group, although the difference was not significant statistically. Abnormal contraction waveforms were more frequent in the post-EST group. One patient in the post-EST group had persistent dysphagia in the absence of endoscopically documented stricture at the time of manometric study. This study shows frequent occurrence of esophageal dysmotility after EST with AA; however, esophageal dysmotility after EST was infrequently associated with motor dysphagia.
Contact properties in nanocrystalline n-GaN in thin film form were studied by depositing nanocrystalline films onto aluminium coated fused silica substrates by high pressure sputtering of Si (1 at%) doped GaN target. Schottky diodes were realized with Au, Ni and Pd as top contacts on the nanocrystalline n-GaN films to examine the contact properties of the diodes thus formed. Variation of current-voltage (I-V) and capacitance-voltage (C-V) characteristics of the Schottky diodes were recorded at different temperatures and analyzed in the light of the existing theories.
Background: Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial pneumonia of unknown etiology often leading to respiratory failure. Over half of IPF patients present with discordant features of usual interstitial pneumonia on high-resolution computed tomography at diagnosis which warrants surgical lung biopsy to exclude the possibility of other interstitial lung diseases (ILDs). Therefore, there is a need for non-invasive biomarkers for expediting the differential diagnosis of IPF. Methods: Using mass spectrometry, we performed proteomic analysis of plasma extracellular vesicles (EVs) in a cohort of subjects with IPF, chronic hypersensitivity pneumonitis, nonspecific interstitial pneumonitis, and healthy subjects (HS). A five-protein signature was identified by lasso regression and was validated in an independent cohort using ELISA. We evaluated the concordance between plasma EV proteome and the lung transcriptome data. Lastly, we compared the molecular pathways overrepresented in IPF by differentially expressed proteins and transcripts from EVs and lung tissues, respectively. Results: The five-protein signature derived from mass spectrometry data showed area under the receiver operating characteristic curve of 0.915 (95%CI: 0.819-1.011) and 0.958 (95%CI: 0.882-1.034) for differentiating IPF from other ILDs and from HS, respectively. We also found that the EV protein expression profiles mirrored their corresponding mRNA expressions in IPF lungs. Further, we observed an overlap in the EV proteome- and lung mRNA-associated molecular pathways. Conclusions: We discovered a plasma EV-based protein signature for differential diagnosis of IPF and validated this signature in an independent cohort. The signature needs to be tested in large prospective cohorts to establish its clinical utility.
Pursuing an environmentally friendly and sustainable system in the modern world has shed new light on green roof technology, a concept that has been introduced previously. However, the rise of urban cities with limited space and increased human activities has ascertained its importance in achieving sustainable agriculture and architecture simultaneously. The numerous lists of benefits have intrigued a new interest among urban developers and landscape architects, resulting in various research on the topic. The article covers the basic concept of green roofs, their functionalities in creating an ecologically balanced environment and why they must be considered in the developing urbanization of the country.
