Special Issue Information

Dear Colleagues,

Over 70% of the earth's surface is covered by water, but in particular bubbles rising in saline water are able to generate one strand, bi-strand, and double-helix motions. These motions pose strongelectric polarization and are subject to compression within sub-bubble vortices, thus assembling RNA and DNA. These are ejected into droplets forming capsid viruses and bacteria cells. Accumulation of microbes in droplets ejected by bursting bubbles, in combination with the microbial concentration at the air-water interface, which can exceed the subsurface concentration by orders of magnitude, contribute to bioaerosol formation. Bioaerosols significantly affect atmospheric processes by contributing to long-range vertical and horizontal transport, influencing atmospheric chemistry, physics and climate.

Primary biological aerosols (PBA) are a subset of atmospheric particles released directly from the biosphere to the atmosphere. They consist of both living and non-living organisms including fungi, bacteria, viruses, pollens and their metabolic products (e.g., endotoxins and mycotoxins). The extent to which biological particles suspended in the air are inhaled greatly depends on their sizes and charge polarities, which control the ability to penetrate the respiratory system and their deposition within it.

Healthy persons are usually adapted to the presence of bioaerosols in the natural environment. However, for people in high-risk groups, an elevated concentration of organic dust can pose an additional health threat, causing cardiovascular diseases, chronic obstructive pulmonary disease, neoplasms, diabetes, etc.

This Special Issue concerns issues in physics, mathematics, chemistry, biology and medicine. We especially encourage the submission of interdisciplinary work and multi-country collaborative research. We welcome original research papers with different study designs, case reports, as well as systematic reviews and meta-analysis. This issue concerns the presented topics, but is not only limited to them.

Please note that all submitted papers must be within the general scope of the Symmetry journal.

Submit your paper and select the Journal “Symmetry” and the Special Issue “Molecule Symmetry, Bioaerosol and Human Health” via: MDPI submission system. Our papers will be published on a rolling basis and we will be pleased to receive your submission once you have finished it.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Bioelectric impedance devices have become a standard of care not only for peritoneal dialysis but also for hemodialysis patients. We compared the most important body composition variables (extracellular water, intracellular water, total body water and fat mass) measured with the multifrequency bioelectric impedance device InBody 720 (MF-BIA) and bioimpedance spectroscopy body composition monitor Fresenius (BIS BCM) in hemodialysis patients (n = 51, 175.1 + 7.8 cm, 82.2 + 15.2 kg) and healthy controls (n = 51, 175.1 + 7.6 cm, 82.3 + 15.3 kg). The MF-BIA InBody 720 device compared to the BIS BCM device showed significantly larger total body water and intracellular water estimates and significantly smaller extracellular water and body fat estimates in hemodialysis patients (p < 0.001). These differences (p < 0.001) were similar in the cohort of healthy controls; moreover, we observed high correlations in all variables between the hemodialysis patients and the healthy controls (0.80–0.95, p < 0.001). The mean relative differences in the order of 8% were lower for extracellular water and total body fat, but the limits of agreement were still wide enough to be clinically significant. We conclude that the results of the measurements with InBody 720 and BCM Fresenius cannot be used interchangeably. Physicians and nutritionists involved in the care of hemodialysis patients should be aware of this discrepancy between the two devices and should try to use the same device to track the body in their hemodialysis population in a longitudinal direction.

This article describes a medical device uses precisely generated vibrations to obtain genetic material (sperm) in injured men, tetraplegics, and paraplegics. A significant advantage is the absence of general anesthesia of the patient. The DC motor of a medical device works with a safe voltage powered by rechargeable or AA cells. The principle of generation of vibration is a crank mechanism. Rotation of the flywheel is converted to rectilinear reciprocating motion. The amplitude is set in the range between 1–4 mm and the frequency is controlled by the RPM of the DC motor. If the stimulation will be followed preciously with the methodology, the process will be completed within 12 min from the beginning of stimulation. The success rate of the device is in the range between 65–85% depending on the patient’s condition and the extent of the spinal cord lesion. The measurement of sinusoidal oscillations was performed by using a stand in which the device was mounted. The amplitude was measured with an accelerometer and then mathematically converted by software Matlab and MS-Excel to the magnitude of the deviation in mm. Measurements have shown that the proposed design meets the requirements for amplitude and frequency. Full article
