Semi-Automatic Labeling and Semantic Segmentation of Gram-Stained Microscopic Images from DIBaS Dataset [PDF]

open access: yesarXiv, 2022
In this paper, a semi-automatic annotation of bacteria genera and species from DIBaS dataset is implemented using clustering and thresholding algorithms. A Deep learning model is trained to achieve the semantic segmentation and classification of the bacteria species. Classification accuracy of 95% is achieved.

The Respiratory Tract and the Environment

open access: yesEnvironmental Health Perspectives, 1977
The primary determinants of pulmonary disease are environmental. The same thinness and delicacy of the air-blood barrier which allows rapid exchange of oxygen and carbon dioxide also reduce its effectiveness as a barrier to inhaled allergens, carcinogens, toxic particles, and noxious gases, and micro-organisms.

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

open access: yesFEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

Effect of vitamin D supplementation to prevent acute respiratory tract infection : an evidence-based case report [PDF]

open access: yes, 2020
Background: One of the frequent health problems that regularly occurs in Indonesia, as a tropical country is an acute respiratory tract infection, including influenza. Since immunological benefit of vitamin D already proven, hypothetically, vitamin D can

The microbiota of the respiratory tract: gatekeeper to respiratory health [PDF]

open access: yesNature Reviews Microbiology, 2017
The respiratory tract is a complex organ system that is responsible for the exchange of oxygen and carbon dioxide. The human respiratory tract spans from the nostrils to the lung alveoli and is inhabited by niche-specific communities of bacteria.

Prevalence of Mycoplasma hominis, Ureaplasma urealyticum, and Ureaplasma parvum detection in urine and respiratory tract samples in Hiroshima, Japan

open access: yesHeliyon, 2023
Background: Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum are commensal bacteria that are associated with colonization and infection of the urogenital tract.

A simple model for the outcomes of collisions between exhaled aerosol droplets and airborne particulate matter: Towards an understanding of the influence of air pollution on airborne viral transmission [PDF]

open access: yesarXiv, 2022
A model that predicts the outcome of collisions between droplets and particles in terms of the distribution of the droplet volume post-collision is lacking, in contrast to the case for droplet-droplet interactions. Taking existing models that successfully predict the outcomes (coalescence, stretching or reflexive separation) and post-separation ...
