Microbial interactions play an important role in initial cell adhesion and the endurance of biofilm toward disinfectant stresses. The present study aimed to evaluate the effect of microbial interactions on biofilm formation and the disinfecting activity of an innovative photocatalytic surfactant based on TiO2 nanoparticles. Listeria monocytogenes, Salmonella Enteritidis, Escherichia coli, Leuconostoc spp., Latilactobacillus sakei, Serratia liquefaciens, Serratia proteomaculans, Citrobacter freundii, Hafnia alvei, Proteus vulgaris, Pseudomonas fragi, and Brochothrix thermosphacta left to form mono- or dual-species biofilms on stainless steel (SS) coupons. The effectiveness of the photocatalytic disinfectant after 2 h of exposure under UV light on biofilm decontamination was evaluated. The effect of one parameter i.e., exposure to UV or disinfectant, was also determined. According to the obtained results, the microbial load of a mature biofilm depended on the different species or dual species that had adhered to the surface, while the presence of other species could affect the biofilm population of a specific microbe (p < 0.05). The disinfectant strengthened the antimicrobial activity of UV, as, in most cases, the remaining biofilm population was below the detection limit of the method. Moreover, the presence of more than one species affected the resistance of the biofilm cells to UV and the disinfectant (p < 0.05). In conclusion, this study confirms that microbial interactions affected biofilm formation and decontamination, and it demonstrates the effectiveness of the surfactant with the photocatalytic TiO2 agent, suggesting that it could be an alternative agent with which to disinfect contaminated surfaces.

Published: April 2023

Multidrug-resistant bacterial infections are on the rise around the world. Chronic infections caused by these pathogens through biofilm mediation often complicate the situation. In natural settings, biofilms are often formed with different species of bacteria existing synergistically or antagonistically. Biofilms on diabetic foot ulcers are formed predominantly by two opportunistic pathogens, Staphylococcus aureus and Enterococcus faecalis. Bacteriophages and phage-based proteins, including endolysins, have been found to be active against biofilms. In this study, we evaluated the activity of two engineered enzybiotics either by themselves or as a combination against a dual biofilm formed by S. aureus and E. faecalis in an inert glass surface. An additive effect in rapidly disrupting the preformed dual biofilm was observed with the cocktail of proteins, in comparison with mono treatment. The cocktail-treated biofilms were dispersed by more than 90% within 3 h of treatment. Apart from biofilm disruption, bacterial cells embedded in the biofilm matrix were also effectively reduced by more than 90% within 3 h of treatment. This is the first instance where a cocktail of engineered enzybiotics has been effectively used to impede the structural integrity of a dual biofilm.

Published: April 2023

Introduction: Based on the results of the Basic Health Research, the prevalence of stunting in children under five is high at 30.79%, this figure is still far above the WHO limit of 20%. This study was conducted to explore local wisdom and socio-culture in families with stunting children.
Methods: This study uses a qualitative study with a phenomenological approach to determine the culture of families with stunting children, This research was conducted in Sungai Tabuk working area, Banjar Regency and was attended by 3 informants, mothers of toddlers who have stunting toddlers and village midwives.
Results: the informant's knowledge about stunting is low. Most mothers of toddlers think that stunting or malnutrition is normal, weight that does not increase or height that is not ideal is considered normal as long as the child does not show symptoms of illness..
Conclusions: From the experience of mothers of toddlers, existing cultural habits still do not support the improvement of nutrition for infants and toddlers in order to prevent stunting. It is necessary to increase awareness in the community to break the stunting chain
Determination of thermal and mechanical indices of an ultrasound probe with an inclined beam-axis in accordance with the new JIS (or IEC Standards)

Published: April 2023

Abstract
According to the new JIS (or IEC Standards), it is necessary to measure the bounded-square output power (P
1×1) for the determination of the soft tissue thermal index (TIS) for both scanning and non-scanning modes of an ultrasonic diagnostic equipment. However, there is no report about how to measure P
1x1 for an ultrasound probe with an inclined beam-axis (UPIB). We designed an angle-corrected 1 cm × 1 cm absorbing mask in accordance with the spirit of IEC 62359 Ed. 2.0 and established a reasonable process for the measurement of TIS and mechanical index (MI) of a paste type probe (PTP), which is a specially designed UPIB for examination of the blood flow in a carotid artery more conveniently and efficiently. Both the TIS and MI of the PTP were much less than 1.0 at all selectable presettings of the blood flow monitor, the FURUHATA device, suggesting it is as safe as a common ultrasonic Doppler diagnostic device.
Applications of Self-Supervised Learning to Biomedical Signals: where are we now
Authors: Del Pup Federico , Atzori Manfredo 
Published: April 2023

<p>Over the last decade, deep learning applications in biomedical research have exploded, demonstrating the ability to often outperform previous machine learning approaches in various tasks. However, training deep learning models requires large amounts of data annotated by experts, whose collection is often time- and cost- prohibitive in the biomedical domain. Self-Supervised Learning (SSL) has emerged as a prominent solution for these problems, as it allows to learn powerful data representations in an unsupervised manner. Despite most applications in biomedical research targeted images, the high amount of recent works targeting biosignals can make it difficult for researchers to have a complete picture of the current situation. The aim of this paper is to outline and clarify the state of the art in the domain. The article briefly summarizes the nature and acquisition modality of biomedical signals, introduces the SSL method, and provides a complete but synthetic overview of the main works applying SSL for the analysis of biomedical signals. The analysis of the scientific literature highlights the importance of SSL, confirming its potential to improve the integration of deep learning into clinical tasks. </p>

В настоящее время все чаще семьи в случае невозможности родить ребенка самостоятельно обращаются к институту суррогатного материнства. Автор, проанализировав действующее семейное законодательство и судебную практику, подчеркивает, что многие вопросы в указанном институте остаются открытыми. Кто родители этих детей? Какую ответственность несут стороны в случае неисполнения условий договора суррогатного материнства? И как правильно разрешать указанные споры по воспитанию детей, возникающие между биологическими родителями и суррогатными матерями? Поэтому чтобы исключить спорные ситуации и неоднозначную судебную практику предлагается внести ряд изменений в действующее семейное законодательство регулирующее правоотношения в области суррогатного материнства.
Currently, families are increasingly turning to the institute of surrogacy in case of inability to give birth to a child on their own. The author, having analyzed the current family legislation and judicial practice, emphasizes that many issues in this institute remain open. Who are the parents of these children? What is the responsibility of the parties in case of non-fulfillment of the terms of the surrogacy agreement? And how to properly resolve these disputes on the upbringing of children that arise between biological parents and surrogate mothers? Therefore, in order to exclude controversial situations and ambiguous judicial practice, it is proposed to make a number of changes to the current family legislation regulating legal relations in the field of surrogacy.

Published: April 2023

Saccharomyces cerevisiae has attracted much technological concern in recent times, owing to their extensive used in food manufacturing, fermented beverages like wine or beer and in promoting the development of industrial biobased products. Saccharomyces cerevisiae also known as yeast are eukaryotic organisms found in a wide ecological niches such as soil, water, air, plants, fruits and plant saps. Saccharomyces cerevisiae strains is the most common yeast known in history for their fermentative ability and are today biotechnologically compliance for industrial production of many products such as ethanol, yoghurt, Cheese, bread, wine and other alcoholic beverages. From their natural habitat, they have been successfully isolated and evaluated for their metabolic and fermentative activities. Investigations by many authors have shown that yeasts can be isolated from palm sap or juices, passion fruit, water melon and pineapple where they colonized as their natural habitats. The isolates from these habitats have also been evaluated and found to have attributes essential for industrial and commercial purposes. The attributes investigated include ethanol production, yoghurt, Cheese, leavening ability for bread making and other dairy products. Besides the aforementioned, yeast are used in the global food processing and manufacturing. They are said to impart improvement in food quality, taste, texture, flavour and nutritive values. In this chapter, I elucidate the potentials of Saccharomyces cerevisiae strains with reference to their industrial and commercial uses. Their classification, cultivation and selection are also discussed.
Detection and Seismic Study of Gravity and Rossby Mode Pulsations in Four Contact Binaries

Published: April 2023

Abstract
We report the detection of gravity (g) and Rossby (r) mode pulsations of four short-period eclipsing binaries, KIC 5439790, KIC 7501230, KIC 9350889, and KIC 9453192 based on the 4 yr Kepler high-precision photometry. Light-curve modeling reveals that the four binaries are all contact systems with small mass ratios. We study the short-term variability of the light-curve residuals after the removal of the binary model and attribute them to the g- and r-mode pulsations that stem from the primary stars. By introducing a new criterion, we attempt to identify period-spacing patterns in the Fourier spectra, which refers to the determination of the rotation rates of stellar interior and envelope as well as the asymptotic period spacings of the pulsating stars. It is interesting to find that the rotation rates of the stellar envelopes are all nearly equal to the orbits. The near-core rotations, however, are significantly slower by about 10%. Based on the derived asymptotic period spacings, stellar parameters were constrained from asteroseismology models. The pulsators are revealed to be evolved main-sequence stars with high metallicities.
Thermal Models of Asteroids with Two-band Combinations of Wide-field Infrared Survey Explorer Cryogenic Data

Published: April 2023

Abstract
We used the reparameterized Near-Earth Asteroid Thermal Model to model observations of a curated set of over 4000 asteroids from the Wide-field Infrared Survey Explorer in two wavelength bands (W2–3 or W3–4) and compared the results to previous results from all four wavelength bands (W1–4). This comparison was done with the goal of elucidating unique aspects of modeling two-band observations so that any potential biases or shortcomings for planned two-band surveys (e.g., the NASA Near-Earth Object Surveyor Mission) can be anticipated and quantified. The W2–3 two-band fits usually yielded slightly smaller diameters than the four-band fits, with a median diameter difference of −10%, with the 5% and 95% quantiles of the distribution at −32% and −1.5%, respectively. We conducted similar comparisons for W3–4, in part because the longest wavelength bands are expected to provide the best two-band results. We found that the W3–4 two-band diameters are slightly larger than the four-band results, with a median diameter difference of 11% and the 5% and 95% quantiles of the distribution at −2.1% and 26%, respectively. The diameter uncertainty, obtained with bootstrap analysis, is larger by 30% and 35% (median values) for the W2–3 and W3–4 fits, respectively, than for the corresponding four-band fits. Using 23 high-quality stellar occultation diameters as a benchmark, we found that the median errors of W2–3 and W3–4 diameter estimates are −15% and +12%, respectively, whereas the median error of the four-band fits is 9.3%. Although the W2–3 and W3–4 diameters appear to have greater systematic errors and uncertainties than their four-band counterparts, two-band estimates remain useful because they improve upon diameter estimates obtained from visible photometry alone.

Mining activities have significant impacts on the environment, particularly in terms of the destruction of natural habitats, biodiversity loss. With the increasing awareness of the importance of ecological restoration and conservation, there is a growing need to study and understand the flora that thrives in mining sites for successful reclamation efforts. This study aimed to investigate the floristic composition and plant diversity of four phosphate mine sites (PMSs) in Morocco, namely Bou Craa mine (BCM), Ben Guerir mine (BGM), Youssoufia mine (YSM), and Khouribga mine (KHM).
The study found a total of 215 vascular plant species from 166 genera and 49 taxonomic families across the four sites. BGM was the most diverse site with 120 plant species, followed by KHM with 75, YSM with 57, and BCM with 54. Compositae family species were the most common at BGM and KHM, while Amaranthaceae species were dominant at BCM, and Poaceae and Compositae at YSM. Therophytes (annual species) were the most common functional group (45.0%), followed by chamaephytes (19.6%) and hemicryptophytes (15.9%).
Atriplex nummularia and Chenopodium album were the most common species found at all four sites, while Atriplex semibaccata, Bassia muricata, Haloxylon scoparium, and 12 other species were common at three sites. However, 156 plant species were found at only one site. The findings of this study highlight the significant abundance of plant species in Moroccan PMSs and provide a basis for successful ecological engineering rehabilitation plans. The study emphasizes the importance of studying the indigenous plant species that naturally populate these marginal lands to ensure successful reclamation efforts.
