Sixty children had 65 pieces of foreign bodies, of which 16 pieces were impacted in the esophagus, 41 in the stomach and 8 in the duodenum. Sixty pieces of foreign bodies were successfully removed from 56 children without any complications. But 5 pieces of foreign bodies in 4 children failed to be taken out because the foreign bodies lodged in the second part of the duodenum. The successful rate was 93.3% in respect to the number of children, and 92.3% in respect to the pieces of foreign bodies. Among all the foreign bodies taken out, the longest one was 150 mm in length and 34 mm in width. Endoscopy was performed under general anaesthesia for most of the children with foreign bodies. The endoscope for adults has been used safely in these children.展开更多

Bacterial community composition involved in biofilm formation in extremely high rainfall areas like Cherrapunjee has not been reported. The present study was undertaken to characterize bacteria involved in biofilm formation on different substrata in water bodies of Cherrapunjee, the highest rainfall receiving place on planet earth and to assess if the continuous rainfall has an effect on nature and colonization of biofilm bacteria. We developed the biofilm bacteria on stainless steel and glass surfaces immersed in water bodies of the study sites. Isolation of biofilm bacteria were performed on different culture media followed by estimation of protein and carbohydrate content of bacterial exopolysaccharides. 16S rRNA gene sequences were amplified for molecular characterization. The results showed that the biofilm bacterial diversity in water bodies of Cherrapunjee was influenced by substratum and was observed more in stainless steel than glass surface. Scanning electron microscopy images revealed that biofilm microstructure may represent a key determinant of biofilm growth and physiology of associated bacteria. The overall protein content of the extracted EPS of all the isolates were relatively higher than the carbohydrate content. Diverse bacteria proliferated on the substrata regardless of each other's presence, with more diverse bacteria colonizing the substrata on 7th day compared to 15th day of incubation. The biofilm bacteria compositions in the highest rainfall receiving habitat were not distinctly different from reports available, hence not unique from other water bodies.展开更多

Currently, oli...Olive (Olea europaea L.) tree is one of the most extensive and important agricultural crop in Mediterranean countries due to its beneficial health and nutritional properties and its high economic value. Currently, olive tree constitutes the sixth most important cultivated plant in the world, spreading from the Mediterranean region of origin to new production areas such as Australia, South and North America and South Africa. However, the mobilization processes of storage materials i.e. reserve proteins during seed germination, which are largely involved in essential physiological process including plant growth and development, remain poorly understood. Morphometric and immunohistochemistry analyses of protein bodies contained in olive seed storage tissues, cotyledon and endosperm, were performed by using different microscopy techniques, including light (bright-field and fluorescence) microscopy and transmission electron microscopy. Furthermore, we used legumin-like proteins (11S-type globulins) as a molecular marker to study the mobilization of reserve proteins from PBs of cotyledons at germinating seedling stages by using immunofluorescence assays. Results demonstrated that cotyledon and endosperm are characterized by distinct PBs populations containing legumin-like proteins, distinctly discriminated by the number of PBs per cell and tissue, size, immunofluorescence and histochemical staining. These features reflect differential PBs biogenesis during development and maturation processes in olive seed tissues endosperm and cotyledon, in relation to proteins (polypeptides) final composition, SSPs processing and/or packaging during seed maturation. Three different mobilization patterns of legumin-like proteins were identified for the first time in cotyledon PBs during seedling germinating process. Mature proteins composition and/or processing, cell types and enzyme composition and/or differential activation have been discussed as key features determining how proteins mobilize from PBs for further degradation in the cotyledon.展开更多

Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) are the most common forms of the dementia, accounting for 60% - 80% and 10% - 20% of all cases, respectively. DLB is defined by widespread neocortical, limbic and brainstem Lewy bodies but frequently accompanied by variable levels of AD pathology. This pathological and clinical overlap makes their differential diagnosis complicated. Recent advances in the identification of disease bio-markers now make it possible to detect and distinguish their pathology in the early or preclinical stage of the diseases, even in cognitively normal individuals. In addition to the key biomarkers (amyloid β or Aβ, tau and α-synuclein), neurotrophins such as cocaine- and amphetamine-regulated transcript (CART) have also drawn attention due to their expressions and functions. This article summarizes the progress in the definition, pathology and diagnosis of dementia, with a focus on potential biochemical markers in the cere-brospinal fluid (CSF) in the differential diagnosis of the main forms of dementia. To prediction or early diagnosis of dementia, the role of specific and sensitive CSF biomarkers seems to be crucial in a routine clinical setting. The concerns and challenges in the biomarker field are also discussed.展开更多

文摘Parkinson’s disease(PD)is one of the primary vital degenerative diseases that affect the Central Nervous System among elderly patients.It affect their quality of life drastically and millions of seniors are diagnosed with PD every year worldwide.Several models have been presented earlier to detect the PD using various types of measurement data like speech,gait patterns,etc.Early identification of PD is important owing to the fact that the patient can offer important details which helps in slowing down the progress of PD.The recently-emerging Deep Learning(DL)models can leverage the past data to detect and classify PD.With this motivation,the current study develops a novel Colliding Bodies Optimization Algorithm with Optimal Kernel Extreme Learning Machine(CBO-OKELM)for diagnosis and classification of PD.The goal of the proposed CBO-OKELM technique is to identify whether PD exists or not.CBO-OKELM technique involves the design of Colliding Bodies Optimization-based Feature Selection(CBO-FS)technique for optimal subset of features.In addition,Water Strider Algorithm(WSA)with Kernel Extreme Learning Machine(KELM)model is also developed for the classification of PD.CBO algorithm is used to elect the optimal set of fea-tures whereas WSA is utilized for parameter tuning of KELM model which alto-gether helps in accomplishing the maximum PD diagnostic performance.The experimental analysis was conducted for CBO-OKELM technique against four benchmark datasets and the model portrayed better performance such as 95.68%,96.34%,92.49%,and 92.36%on Speech PD,Voice PD,Hand PD Mean-der,and Hand PD Spiral datasets respectively.
文摘Bacterial attachment is influenced by the cell surface, attachment media and other environmental factors. Bacterial community composition involved in biofilm formation in extremely high rainfall areas like Cherrapunjee has not been reported. The present study was undertaken to characterize bacteria involved in biofilm formation on different substrata in water bodies of Cherrapunjee, the highest rainfall receiving place on planet earth and to assess if the continuous rainfall has an effect on nature and colonization of biofilm bacteria. We developed the biofilm bacteria on stainless steel and glass surfaces immersed in water bodies of the study sites. Isolation of biofilm bacteria were performed on different culture media followed by estimation of protein and carbohydrate content of bacterial exopolysaccharides. 16S rRNA gene sequences were amplified for molecular characterization. The results showed that the biofilm bacterial diversity in water bodies of Cherrapunjee was influenced by substratum and was observed more in stainless steel than glass surface. Scanning electron microscopy images revealed that biofilm microstructure may represent a key determinant of biofilm growth and physiology of associated bacteria. The overall protein content of the extracted EPS of all the isolates were relatively higher than the carbohydrate content. Diverse bacteria proliferated on the substrata regardless of each other's presence, with more diverse bacteria colonizing the substrata on 7th day compared to 15th day of incubation. The biofilm bacteria compositions in the highest rainfall receiving habitat were not distinctly different from reports available, hence not unique from other water bodies.
文摘Olive (Olea europaea L.) tree is one of the most extensive and important agricultural crop in Mediterranean countries due to its beneficial health and nutritional properties and its high economic value. Currently, olive tree constitutes the sixth most important cultivated plant in the world, spreading from the Mediterranean region of origin to new production areas such as Australia, South and North America and South Africa. However, the mobilization processes of storage materials i.e. reserve proteins during seed germination, which are largely involved in essential physiological process including plant growth and development, remain poorly understood. Morphometric and immunohistochemistry analyses of protein bodies contained in olive seed storage tissues, cotyledon and endosperm, were performed by using different microscopy techniques, including light (bright-field and fluorescence) microscopy and transmission electron microscopy. Furthermore, we used legumin-like proteins (11S-type globulins) as a molecular marker to study the mobilization of reserve proteins from PBs of cotyledons at germinating seedling stages by using immunofluorescence assays. Results demonstrated that cotyledon and endosperm are characterized by distinct PBs populations containing legumin-like proteins, distinctly discriminated by the number of PBs per cell and tissue, size, immunofluorescence and histochemical staining. These features reflect differential PBs biogenesis during development and maturation processes in olive seed tissues endosperm and cotyledon, in relation to proteins (polypeptides) final composition, SSPs processing and/or packaging during seed maturation. Three different mobilization patterns of legumin-like proteins were identified for the first time in cotyledon PBs during seedling germinating process. Mature proteins composition and/or processing, cell types and enzyme composition and/or differential activation have been discussed as key features determining how proteins mobilize from PBs for further degradation in the cotyledon.
文摘Dementia is mainly a neurodegenerative disorder involved in several systems, including central nervous system, endocrinology/metabolism system and circulatory system. Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) are the most common forms of the dementia, accounting for 60% - 80% and 10% - 20% of all cases, respectively. DLB is defined by widespread neocortical, limbic and brainstem Lewy bodies but frequently accompanied by variable levels of AD pathology. This pathological and clinical overlap makes their differential diagnosis complicated. Recent advances in the identification of disease bio-markers now make it possible to detect and distinguish their pathology in the early or preclinical stage of the diseases, even in cognitively normal individuals. In addition to the key biomarkers (amyloid β or Aβ, tau and α-synuclein), neurotrophins such as cocaine- and amphetamine-regulated transcript (CART) have also drawn attention due to their expressions and functions. This article summarizes the progress in the definition, pathology and diagnosis of dementia, with a focus on potential biochemical markers in the cere-brospinal fluid (CSF) in the differential diagnosis of the main forms of dementia. To prediction or early diagnosis of dementia, the role of specific and sensitive CSF biomarkers seems to be crucial in a routine clinical setting. The concerns and challenges in the biomarker field are also discussed.
