An Adaptive and Altruistic PSO-based Deep Feature Selection Method for Pneumonia Detection from Chest X-Rays [PDF]

Applied Soft Computing, 2022, 109464, ISSN 1568-4946, 2022
Pneumonia is one of the major reasons for child mortality especially in income-deprived regions of the world. Although it can be detected and treated with very less sophisticated instruments and medication, Pneumonia detection still remains a major concern in developing countries.

A reação em cadeia da polimerase na detecção da resistência à penicilina em Streptococcus pneumoniae Polymerase chain reaction used to detect Streptococcus pneumoniae resistance to penicillin

Jornal Brasileiro de Pneumologia, 2004
INTRODUÇÃO: O Streptococcus pneumoniae é o mais freqüente agente etiológico de infecções respiratórias adquiridas na comunidade e sua resistência aos antimicrobianos tem aumentado nos últimos anos. A determinação da resistência é feita rotineiramente por

Transfer Learning with Deep Convolutional Neural Network (CNN) for Pneumonia Detection using Chest X-ray [PDF]

Appl. Sci. 2020, 10(9), 3233, 2020
Pneumonia is a life-threatening disease, which occurs in the lungs caused by either bacterial or viral infection. It can be life-endangering if not acted upon in the right time and thus an early diagnosis of pneumonia is vital. The aim of this paper is to automatically detect bacterial and viral pneumonia using digital x-ray images.

Polyamine transporter potABCD is required for virulence of encapsulated but not nonencapsulated Streptococcus pneumoniae

PLoS ONE, 2017
Streptococcus pneumoniae is commonly found in the human nasopharynx and is the causative agent of multiple diseases. Since invasive pneumococcal infections are associated with encapsulated pneumococci, the capsular polysaccharide is the target of ...

Movement dynamics of divisome proteins and PBP2x:FtsW in cells of Streptococcus pneumoniae

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance This study answers two long-standing questions about FtsZ dynamics and its relationship to septal peptidoglycan (PG) synthesis in Streptococcus pneumoniae. In previous models, FtsZ concertedly moves from midcell septa to MapZ rings that have

Streptococcus pneumoniae Capsular Polysaccharide

Microbiology spectrum, 2019
The polysaccharide capsule of Streptococcus pneumoniae is the dominant surface structure of the organism and plays a critical role in virulence, principally by interfering with host opsonophagocytic clearance mechanisms.
