ZnO nanoparticles (ZnO-NPs) can be synthesized by chemical, physical and biological methods; many studies have indicated that biologically synthesized ZnO-NPs have ecofriendly benefits over physically and chemically synthesized ZnO-NPs. This study was carried out to evaluate the differences in characteristics and effects on pathogenic bacteria between ZnO-NPs synthesized by a chemical method and a biological method using the marine green alga Ulva fasciata. Additionally, the synergistic or antagonistic effects of loading ZnO-NPs synthesized by chemical and biological methods on antibiotics are investigated. The results show that there are differences in the characteristics of ZnO-NPs synthesized by the various methods, as determined by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). ZnO-NPs had antibacterial activity against Staphylococcus aureus, , Salmonella enterica subsp. salamae (Em.1-EGY015), Aeromonas hydrophila, Escherichia coli O157 (KY797670) and Bacillus cereus SH06; moreover, green-synthesized ZnO-NPs were more effective against pathogenic bacteria than chemically synthesized ZnO-NPs. The minimum inhibitory concentration (MIC) of ZnO-NPs synthesized by the green method was less than that of ZnO-NPs synthesized by the chemical method. The results demonstrated that the synergistic or antagonistic effects of ZnO-NP loading on antibiotics (ampicillin/sulbactam, tobramycin, flucloxacillin, chloramphenicol, amoxicillin, cephalexin, ofloxacin, and neomycin) varied according to the type of pathogenic bacteria, antibiotic, and method of synthesis of ZnO-NPs.

Published: February 2023

The following article analyzes the presentation of Empress Theodora – the wife of Emperor Justinian and the most popular woman in the history of Byzantium – in contemporary Latin sources. Victor of Tunnuna, Liberatus of Carthage, and the author of selected biographies in Liber Pontificalis focused in their works primarily on the issues of religious policy of the empire and described the person of the ruler throughout this prism. Considerations on the parallel monophysite source tradition allow for a hypothesis about the schematicism of creating the image of Theodora as the main enemy of Chalcedonian orthodoxy.

Anna Mostowska – preromantyczna protofeministka
Authors:   Uniwersytet Warszawski, Hanuszewicz Zuzanna
Published: February 2023

Anna Mostowska is part of the group of lesser-known, even forgotten, Polish women writers, whose works were written during the first decade of the 19th century. Her biography deserves widespread attention and to be recalled, as she was a pre-romantic protofeminist far ahead of her time. She was a nonconformist, an independent woman, who in 1804, after divorcing her second husband, Tadeusz Mostowski, decided to become financially independent and start writing. In her time, she was one of the very few women scholars and writers, that was also a frequent guest in artistic circles. Moreover, she did not fulfill the cultural and social roles assigned to women of that time, as she was an erudite, patron of the arts, painter, writer and translator.
Strategies and Tactics of the Lithuanian Women’s Movement: Retrospective Analysis
Authors:   Vilnius University, Jurėnienė Virginija
Published: February 2023

The strategies and tactics of the Lithuanian women’s movement helped to change the attitudes of society, political parties, altered political, educational and legal systems and expanded the field of relevant issues on the international level. However, the state’s existence period (1918–1940) was too short for women to be able to fully realise them; thus, most of the formed strategies are relevant today and are realised. The examples of strategy implementation ways show that women’s actions were important for the society and the state and had direct impact on their development. The second strategic period is very important; during this period, Lithuanian women were granted political rights. Novelty of work. The article provides the correct date of women being granted suffrage based on historical sources, i.e., 20 November 1919, the law on election of the Constituent Assembly of Lithuania. It does not coincide with the notion established in the Lithuanian historiography that the date is 2 November 1918. The author proves that this error emerged due to incorrect interpretation of the article in the 2 November 1918 Lithuanian Temporary Constitution on the person’s (citizen’s) rights. Moreover, the researcher takes on a new approach towards the Lithuanian women’s movement through the prism of implementation of strategies and tactics. This approach towards the history of the Lithuanian women’s movement is new. The methods of descriptive, analytical and comparative research. The sources studied are: historical sources, including state documents, archival materials, monographs, survey studies, biographical studies, memoirs, private letters, press, etc.

Authors:   Uniwersytet Marii Curie-Skłodowskiej, Szwed-Walczak Anna
Published: February 2023

The research was aimed at reconstructing the media image of feminism which was presented in the most popular Polish magazines dedicated to women in the years 1989–1992. The research time period corresponded to the first stage of the system transformation in Poland. It was initiated by the year in which the Round Table Talks were held and it ended with the adoption of the so-called “Small Constitution” in 1992. There were three detailed questions formulated: 1. How was feminism defined in the Polish women’s press? 2. How often was this topic subject to discussions? 3. Which determinant factors affected the image of feminism depicted by the editorial offices of the women’s press? The text analysis and the content analysis revealed that the image of feminism in the Polish women’s press in the period under study was fragmentary and cultural, historical and political aspects exerted a crucial influence on its structure.

Objective :To investigate the predictive value of no reflow phenomenon in interventional therapy by measuring plaque quantitatively with optical coherence tomography (OCT).
 Methods:196 patients with acute ST segment elevation myocardial infarction who visited the Department of Cardiology of the Second Affiliated Hospital of Zhengzhou University from January 2020 to January 2022 were selected as the study objects. According to whether there was no reflow during the operation, they were divided into no reflow group (46 cases) and normal flow group (150 cases). Systematically collect general clinical data and coronary angiography related data of patients through inpatient cases, measure fiber cap thickness and lipid core angle of diseased vascular plaque through optical coherence tomography, and analyze the relationship between fiber cap thickness and no reflow phenomenon  
Results:BMI, LDL, phospholipase A, the proportion of family history of coronary heart disease, and the thrombus load in the no reflow group were higher than those in the normal flow group (P<0.05), while the thickness of the fibrous cap was lower than that in the normal flow group (P<0.05); Further multivariate logistic regression analysis showed that fiber cap thickness, phospholipase A and severe thrombosis load were independent risk factors for non reflow phenomenon (P<0.05); Further ROC curve analysis found that the thickness of fiber cap had a high predictive value for no reflow phenomenon, and the best cutoff value for no reflow was 95, AUC: 0.926 (95% CI: 0.891-0.961, P<0.001).
Conclusions: Optical coherence tomography can predict the occurrence of no reflow phenomenon by measuring the fiber cap thickness quantitatively. The prediction effect is the best when the fiber cap thickness is 95.

Published: February 2023

This study aimed to investigate electrophysiological features of radiofrequency ablation surgery in patients with the atrial fibrillation (AF). Fifty patients were included in this study and evenly divided, with 25 AF patients in the experiment group and 25 patients with arrhythmias in the control group. General clinical materials in the two groups were collected. Then, patient number of pulmonary vein antrum potential trial, intra-right atrial conduction time, intra-left atrial conduction time, interatrial conduction time, conduction time between atrium, and pulmonary veins trials were utilized to measure the efficacy of radiofrequency ablation surgery in patients with AF and clarify the relationship between AF and electrophysiological features in the atrium and pulmonary veins. Our study findings showed that conduction time interval between the atrium and pulmonary veins trial by radiofrequency ablation surgery were significantly less than those in pre-treatment AF patients. We can conclude that radiofrequency ablation surgery can effectively treat AF patients by relieving the electrophysiological dysfunction, and radiofrequency ablation can be used to prevent the development of AF.
Actinide concentration from lunar regolith via hydrocyclone density separation
Authors: J Schubert Peter
Published: February 2023

Beneficiation of regolith to concentrate the high-density ore fraction from the gangue can be accomplished through momentum transfer methods, such as ballistic deflection or cyclonic separation.This study explores the extraction of actinide-bearing minerals from lunar regolith based on the difference in apparent density between thorium-bearing minerals (e.g. ThO2ρ=10) from silicates (e.g. SiO2ρ=2.65).Thorium content in lunar regolith ranges from single-digit parts per million (ppm) to as high as 60 ppm.Concentrating thorium-bearing minerals is a required first step in the preparation of fission fuels for a nuclear reactor in which all of the radioactive operations are performed 380,000 km from the Earth’s biosphere. After comparison with ballistic deflection, cyclone separation with a non-volatile fluid carrier was chosen for further study.With sieving to separate particles by size, such a hydrocyclone can be used to efficiently separate the dense fraction from the lighter minerals.Design equations were used to fabricate an at-scale apparatus using water, iron particles, and glass beads as simulants.Results show the ability to effect a 2 to 5.4 % increase in dense fraction concentration each pass, such that 95% concentration requires between 50 and 100 passes, or a cascade of this many apparatuses.The selection of a suitable fluid for safe and low-mass transport to the Moon is part of a techno-economic analysis of the cost and infrastructure needed to produce highly-purified thorium minerals on the lunar surface.

Authors: Yasmeen Hafiza Humaira , Khalil Iqra
Published: February 2023

Objective: To compare astigmatism after phacoemulsification and extracapsular cataract extraction technique. Method: It was a hospital-based cross-sectional study conducted at Zainab Medicare hospital Haroonabad from September 2018 to May 2019. A sample size of 80 patients having cataract, age 41 to 70 years was included in this study. Slit lamp examination was performed for anterior segment evaluation and astigmatism was determined with autorefraction and keratometry. Result: Phaco technique was more reliable. The means and the standard deviation of phaco post op astigmatism was 0.7860 ±.48880 and ECCE post op astigmatism was 3.6310±1.96236 which indicated that the degree of astigmatism increases after extra capsular cataract extraction technique. The significant level was 0.00 which showed that the phaco technique is highly significant. Conclusion: Corneal astigmatism was almost similar in two groups prior to surgery but after the cataract surgery the astigmatism significantly decreased after phacoemulsification group at 2 weeks follow-up, the results indicated that phaco may be considered superior to ECCE. No suturing is required in phaco and hence lesser chances of post op astigmatism.
Visual outcomes after bilateral implantation of a new generation diffractive trifocal intraocular lens
Authors: Dubey Shubhangi
Published: February 2023

Cataract surgery today has become more of a refractive surgery with high patient expectations and demand of independence from glasses. Modern cataract surgery is characterized by obtaining precise postoperative target refraction with the premium intraocular lenses (IOLs) available today. The multifocal IOLs are designed to reduce the spectacle dependence after cataract surgery. Previously a variety of studies were performed that confirmed a significant improvement in uncorrected visual acuity after implantation of multifocal IOLs as compared to monofocal IOLs.1‒5 Initially multifocal IOLs that were designed were having a bifocal design which allowed the patient to have a good distance and near visual acuity post operatively, but near vision came at the expense of reduced contrast sensitivity.6‒8 Nowadays, due to increased use of computers the preference of spectacles has changed from near to intermediate distance. In this sense achieving an intermediate vision with an IOL is a good option. The IOL technologies in the latest times help in rehabilitating the distance and near visual acuities and also by incorporating a component of intermediate vision (ie, trifocal IOLs) to ensure spectacle independence.9‒11 The present study aims at assessing the performance of AT LISA tri 839MP trifocal diffractive IOL in terms of visual acuity and independence from spectacles. The other objectives are to assess changes in the distance, near and intermediate visual acuities, contrast sensitivity postoperatively and plotting the defocus curves.

Authors: CO Fadamiro , KO Ajite
Published: February 2023

Aim: To determine the acceptance rate and barrier to uptake of Trabeculectomy among glaucoma patients in our Hospital. Method: All newly diagnosed cases of primary open angle Glaucoma patients seen from May to October 2018 at the glaucoma clinic of Ekiti State University Teaching Hospital were interviewed for the study using a semi-structured questionnaire designed for it. The data obtained were coded and analyzed using Statistical Package for Social Sciences (SPSS) Version 15. Result: One hundred and thirty-eight primary open angle glaucoma patients with age range 23 to 82years, mean of 58.2 SD+14.6 were analyzed for this study, they comprised of 71males and 67 females, m: f ratio 1.05:1. Twenty four (17.4%) accepted surgery as against 114 (82.6%) that rejected it, fear of going blind was the most common reason for rejection (82.5%), other reasons include seeing well and bad experience of some other patients that had surgery. Conclusion: There is a low level of acceptance for Trabeculectomy in this study due mainly to fear of going blind. There is therefore the need for counselling of glaucoma patients on the benefit and safety of Trabeculectomy in order to reduce the magnitude of blindness from the disease.

Published: February 2023

Purpose: Aim of this study was to correlate head posture, working distance and luminance with Myopia. Methods: 300 myopic aged 7 to 18 years (mean 13.5 years) without spectacles male students were included. The subjects under study were analysed through comprehensive examination (visual acuity, objective and subjective refraction). They were asked to recite Holy Book for ten minutes; a random picture was clicked and posture was measured by drawing neck angle at the picture. Their habitual maximum and minimum working distance was measured when student move backward and forward. Luminance level was recorded of each student at place where he used to study. Results: Results of this study showed a negative correlation between myopia and posture reading ([95% CI] RE r= -0.07, p = 0.228, LE r= -0.079, p = 0.173) that depicts if angle decreases then myopia increases. A downhill and significant correlation was found between luminance level and myopia ([95% CI] RE r= -0.700, p = 0.000, LE -0.693, p = 0.000); as the lux (luminance) gets reduced the spherical equivalent gets increased and vice versa. There is a negative correlation between spherical equivalent and minimum working distance ([95% CI] RE r= -0.612, p = 0.000, LE r= -0.588, p = 0.000). A negative correlation between myopia and maximum working distance was found ([95% CI] RE r= -0.634, p = 0.000, LE r= -0.604, p = 0.000). Conclusion: We concluded that variable working distance, adoption of abnormal head posture and low luminance in Religious Schools has noteworthy association with myopia. Eye care professionals should play their vital role to enlighten the community that while performing near tasks all these risk factors should be avoided to halt the progression of myopia.

Published: February 2023

Purpose: To assess the types of phorias in different degrees of myopic patients and different age groups before and after refractive correction. Study design: Descriptive cross-sectional study. Material and methods: This was a comparative cross-sectional study that included 100 patients. Types of phorias in myopic patients were assessed before and after refractive correction. Patients involved are 15-35 years of age groups. Data was collected from the University of Lahore Teaching Hospital. Results: A total of 100 subjects were participated out of which 52% were males and 48% were females. 38% were 15-20 years, 42% were 21-25 years, 9% were 26-30 years, and 11% of participants were31-35 years of age. Visual acuity before the correction of refractive error was also recorded 42% of participants were observed with 6/6-6/12 visual acuity, 6/18-6/36 visual acuity was reported in 42% subjects and 16% subjects had <6/60 visual acuity. After the correction of myopic error 87% subjects had 6/6-6/12 and 13% subjects had 6/18-6/36 best corrected visual acuity. Degree of myopia was recorded mild in 42% participants, moderate in 42% subjects and severe in 16% subjects. Before the correction of myopia 21% participants were observed with esophoria, 54% had exophoria and 25% subjects were orthophoric. After refractive correction 13% participants were esophoric, 28% were exophoric and 59% were orthophoric while measuring horizontal phoria at distance. In vertical phoria before correction 14% participants were hyperphoria, 1% were hypophoria and 85% were orthophoric. After best correction 5% participants were recorded as hyperphoria, 1% were hypophoria and 94% were orthophoric. Conclusion: Horizontal and vertical phorias were evaluated at distance with Maddox rod. It is concluded that after correction the frequency of horizontal phorias is high than vertical phorias. In horizontal phorias exophoric pattern has significant frequency. Exophoria can also result due to weak fusional reserves. Fusional convergence eliminates the disparity of retinal images and maintain exophoria in myopic patients. So, convergence weakness and excess of divergence leads to exophoria in myopic patients. Mostly exophoric participants are reported from age range of 15 to 20 years. After refraction if patient still have asthenopia symptoms proper evaluation and management should be made for latent squint. By treating and managing the latent squint the chances of phorias to convert in manifest squint will be minimize.
COVID-19 and childhood obesity
Authors: Marks Ray
Published: February 2023

Childhood obesity, which is on the rise, is a risk factor for, as well as a possible negative outcome, of the restrictions enacted to protect against the novel corona virus 19 infectious disease [COVID-19]. To examine this premise the PUBMED and GOOGLE SCHOLAR data bases were sourced for relevant data published between January 2020 and March 2022 on the topic of COVID-19 and childhood obesity. These data bases show most current publications tend to portray a negative impact of COVID-19 lockdown policies on childhood obesity prevalence and outcomes. Many calls are hence being made for urgent efforts to mitigate a possible tsunami of chronic ill health and pain both in the short term, as well as in the long term among the millions of currently affected overweight children.

Published: February 2023

Introduction: Percutaneous Endoscopic Gastrostomy (PEG) is considered a low-risk procedure; however, side effects may happen, the majority being of mild severity. Among the severe complications, few cases entitled “Buried bumper syndrome” (BBS) have been described. BBS corresponds to the migration of the internal fixation along the stoma tract, becoming lodged between the external wall of the stomach and the skin, which can be associated with local infection, peritonitis, and/or necrotizing fasciitis. Case description: On 06/03/2021 at 29 years old male patient, with no relevant medical history is admitted to the São João Hospital with an extensive midbrain and brainstem hemorrhagic lesion, shown on CT scan. The patient lost his oral route and ability to communicate. Due to severe dysphagia, a PEG was placed without immediate complications. 3 days later, the nursing team reported peri-stomal food losses and local inflammation, with the patient unable to verbalize any complaint. Although there was an adjustment of the PEG by the gastroenterologist, these reports recur for the next week, being detected by the medical team after a routine full body evaluation of the patient. After a new evaluation, a CT was performed, reporting “PEG, whose balloon is located between the median abdominal wall and the anterior surface of the left hepatic lobe”, compatible with the complication described as “buried bumper syndrome”. Discussion: The present case emphasizes the importance of correctly identifying the complications after undergoing PEG, as well as the risk factors and consequences associated with this syndrome, namely in patients with post-stroke status, whose communication is often compromised, and special attention must be given

Published: February 2023

Expansion of psychoactive hallucinogens in mental health continues to be a major trend. Several psychoactive molecules including psilocybin and MDMA continue to move through the FDA approval process with clinical trials.1 In the meantime, off-label ketamine medically supervised programs and indigenous plant ceremonies continue to expand.2,3 This study explores the potential benefits of High Intensity Embodied Stimulation (HIES) which is part of the Body Logic Program (10–12 sessions), and its ability to mimic psychoactive states of mind.4 The study employs a questionnaire of mystical experience, developed at Johns Hopkins, the Mystical Experience Questionnaire (MEQ), that assesses mystical experiences in seven domains. Fifty-six participants who finished the Body Logic Program, completed the questionnaire. Comparative data from Psilocybin participants, post psilocybin, as well as a placebo group (non-psilocybin) provide reference data.5,6 Results show that 51% of HIES participants report a strong or extreme mystical experience. Another 31% of HIES participants report a moderate strength of mystical experience. Results suggest that Body Logic Program can provide an efficacious system for mystical experience and body-mind integration.

This work aims to investigate freshwater fish exploitation status in three Tunisian reservoirs: Siliana, Lahjar and Kasseb associated with the examination of progress in the zoo-sanitary registration. Three types of operators at these reservoirs were identified: a promoter, a fishery development group, and independent fishermen. The only operator who has all the required documents for the zoo-sanitary registration, is the promoter operating at Lahjar Reservoir. The SWOT analysis applied to Siliana, Lahjar and Kasseb reservoirs allowed us to highlight the differences between the three modes of exploitation and to identify their strengths and weaknesses. Along with these findings, the analysis revealed factors that may directly or indirectly affect the reservoirs and made it possible to elaborate new perspectives which would help improve the inland fish farming sector in Tunisia.
Oil quality of by- products of marine fish during processing methods
Authors: Hossain Khandakar Zakir
Published: February 2023

By- products that are not regarded as ordinary saleable products (fillet, round, eviscerated or beheaded fish), but which can be recirculated after treatment. Normally oil is produced from by-products of marine fatty fish species such as cod, anchovy, capelin, sardine, salmon, tuna, mackerel, Norway pout, Atlantic herring, sand eel etc. It is possible to extract oil by different process such as wet reduction, hydrolysis, silage, dry rendering and acid - alkali aid. Fish roe has high concentrations of lipids. Hydrolysis was better than wet rendering method as there was a chance for lipid oxidation in the wet rendering method. High quantity and quality of phospholipids were generated from the lipid fraction in the dry rendering process. To ensure high quality of produced products, it is important to process by-products immediately after production. It is also needed to increase the utilization of marine by- products by increasing knowledge on the chemical composition and stability of the by- products.
Polyculture method of Vietnamese koi and monosex tilapia in pond- A Mini Review
Authors: Hossain Khandakar Zakir
Published: February 2023

Vietnamese koi and monosex tilapia have potential for production in a polyculture as both fish species grow very fast and are adapted in same land. 30 decimals – several acres of land can be selected as pond for the polyculture of Vietnamese koi & monosex tilapia.1 The average size of fry is 2–3 gm and 300–350 pieces/ decimal mixed fry of koi and tilapia can be stocked in the pond for commercial fish culture.2 The protein content of the feed should be minimum 30% as koi fish needs higher protein content in their feed for the better growth.3 The average weights of Vietnamese koi and monosex tilapia are 300 gm and 400 gm within a four- month culture period.4,5 The productions of Vietnamese koi and monosex tilapia are about 12000 kg/hectare and 9000 kg/hectare after four months of the culture period.4,5 Although there are few drawbacks to culture of the fish species, but due to their fast growth rates, farmers should culture these fishes more commercially in polyculture system.

Sea urchin gonads are a prized gourmet product in many areas of the globe, and wild populations are threatened by increasing demand, making this species a very desirable product in aquaculture. Due to the unique needs of each stage of the life cycle, a viable food protocol that seeks to satisfy each stage while optimizing production profitability is required. The objective of this work was to test a formulated feed for sea urchins, through the analysis of somatic growth, gonad development and their fatty acid profile. These results were compared with sea urchins fed natural food (Ulva spp.) At the end of the trial Paracentrotus lividus juveniles fed inert diet had higher total wet weight gain, total specific growth rate, and gonadosomatic index than those fed with macroalgae. However, histological observations did not reveal differences in the maturation state of the gonads. In comparison to sea urchins fed fresh Ulva spp., inert diet showed higher total wet weight gain and higher total specific growth rate. Fatty acid contents of the gonads of each treatment were found to be similar. The DHA levels in the gonads of sea-urchins fed the formulated feed were significantly higher. It was possible to record the biosynthesis activity of some fatty acids such as 20:4 ω 6, 16:4 ω 3, and 20:3 ω 3. It was found that the presence of some essential fatty acids, such as DHA and EPA, in the gonads is only dependent on the food profile. The addition of a DHA-rich ingredient in the formulated feed may have been preponderant in the constitution and development of the sea-urchins’ gonads.

Sterile body sites, if infected by micro-organisms than it can lead to severe morbidity and mortality. Infections caused by multidrug resistant (MDR) bacteria remain a public health threat for patients and health care workers. Therefore early diagnosis and prompt initiation of empiric treatment is necessary. Hence, this study aimed at assessing bacterial profiles and their antimicrobial susceptibility patterns (AST) from body fluids and also looks for multidrug resistant organisms. Methods: A retrospective study was conducted from Jan 2017 to dec 2017 by recruiting 1800 study samples. Different body fluids were collected and cultured on Blood agar, MacConkey agar and chocolate agar then incubated aerobically and micro-aerobically. Moreover, gram staining and White blood cell count (WBC) were performed for all collected body fluids sample. Bacterial identification was made using colony morphology, gram stain and biochemical tests. Antimicrobial susceptibility testing was performed on Muller-Hinton agar using disk diffusion method. Results: Overall 15% (n=270/1800) of the body fluids had bacterial growth. Most bacteria were isolated from Cerebrospinal Fluid (CSF) 56.4% and pleural fluids 34.3%. Most frequent bacterial isolates were K. pneumoniae 66.7% followed by, alpha streptococcus30% (n=8/54) and E.coli Gram-negative and gram-positive bacteria showed highest resistance for Gentamycin (76%) and Erythromycin (59%) respectively. The MDR level recorded was 62.9%. Conclusion: Significant numbers of bacteria with high MDR level were isolated from body fluids that call all health care workers and policy makers for concerted efforts for prudent antibiotic use, and limit the transmission of MDR bacteria in hospital and community settings. Regular monitoring of antimicrobial resistance patterns is essential. Low culture positivity may be due to presence of anaerobic; fastidious organisms with lack of enrichment techniques & prior antibiotic administrations.

Phosphate solubilizing Bacillus megaterium was isolated from non rhizospheric soils. Five isolates were identified by 16s rDNA sequencing. According to sequencing and phylogenetic tree analysis, these five isolates were in high similarity with B. megaterium. Abiotic stresses such as temperature, pH and salt tolerance of five strains were examined for the application for abiotic stressed agricultural soils. All five strains could grow well above 40ºC. For pH, five strains demonstrated their growth on minimal media at pH 9 but the growth rates were decreased. Among abiotic stress factors, to obtain salt tolerance phosphate solubilizing B. megaterium was the main objective of this research work. So, salt tolerance of isolates were screened preliminary, all five strains had the ability to grow on minimal media containing 6% NaCl concentration but the growth rates were not in high rates. Preliminary screening results enhanced to continue for quantative determination of phosphate solubilization under salt stressed conditions. In detection of phosphate solubilization by the method of Olsen P, all five strains could solubilize insoluble phosphate, Tricalcium phosphate, under NaCl stressed conditions. Among 4%, 5% and 6% NaCl concentrations, soluble phosphate concentrations released by five strains were decreased with increasing NaCl concentrations, but it was not obviously different.

The objective of the study reported herein was to document the myxomycetes (slime molds) associated with bison dung and cow dung in the temperate prairies of North Dakota. We hypothesized that there is a significant difference between the myxomycetes on bison dung and cow dung. The data were analyzed for any significant statistical differences between the two types of dung, using jmp statistical software. We concluded that there was a significant difference between bison dung and cow dung, with statistical p-value <0.0001*; hence, we rejected the null hypothesis. Reciprocal Simpson’s diversity indices for bison dung and cow dung were 3.01 and 3.03, respectively. The pH recorded for dung samples ranged between 6.48 and 7.41, with the majority of species associated with weak acidic-weak basic conditions.

In order to investigate the influence of trophic state from a subtropical reservoir in the state of São Paulo, Brazil, in the competition between the species dominant, Raphidiopsis raciborskii and Monoraphidium contortum, an assay was carried out of interaction between these microorganisms simulating the reservoir in its current conditions, mesotrophic, and another in a supereutrophic condition, as well as detect the production of saxitoxin by cyanobacteria. The experiments were conducted in a climate-controlled room for 15days in triplicate for pure and mixed cultures of each species. Growth curves were developed according to the biovolume-to-biomass and were calculated the growth rates. The saxitoxin synthesis was determined by ELISA. When simulating the mesotrophic and supereutrophic environments, R. raciborskii did not show any differences in its growth and in the saxitoxin production in the interaction with M. contortum, when compared to its control. Concerning M. contortum, your growth was affected in the interactions with cyanobacteria in both trophic state, although the chlorophyceae presented an increasing specific growth rate. The reduction of the growth of M. contortum in interaction with R. raciborskii shows the increase in trophic state can increase the competitiveness of R. raciborskii in the reservoir and to favor your dominance.
The emergence of extended-spectrum Β-lactamases and carbapenemases from none human sources: The challenges and opportunities

The widespread of extended-spectrum β-lactamases and Carbapenemases from none human is rapidly increasing worldwide. Their presence in all ecosphere manifesting the spotlight of the global public health threat that significantly challenging modern medicine even to the recent one-health system approach. Overuse and misuse of antibiotics are the main triggering factors for antimicrobial selective pressure and clonal dissemination of resistance genes both in human and animal sources. Several none human sources are acting as the main reservoir of various microbial resistance genes leading to create a relentless epidemiological picture in the future. The irrational use of antibiotics in animal’s veterinary medicine reinforce the dissemination of extended-spectrum β-lactamase and carbapenemases especially among Gram-negative bacteria from food-producing animals, birds, lakes, rivers, livestock, animal husbandry, industries, sewages and hospital wastewater to clinical and community settings. Indeed, antimicrobial resistance genes harboured by the bacterial strains are capable of transmitting into clinical and community settings. The global dissemination of the multi-drug resistant extended-spectrum β-lactamases and carbapenemases-synthesizing organism across all ecosystems is limiting the appropriate choice of antimicrobial agents to treat infection judiciously. Lack of public awareness to antimicrobials, poor sanitary conditions, and poor infection prevention measures combined with poor antimicrobial stewardship creates an ubiquitous spread of antimicrobial-resistance genes across the entire ecosystem. The direct or indirect contact of human with contaminated animal products such as urines and faeces that have been contaminated with pathogenic bacteria hastens the horizontal gene transfer of resistance genes across all the community of the bacteria. As a result, a systematic and careful investigation of the potential resistance gene pools reservoirs to address the current emergence of β-lactamases hydrolyzing organisms through integrated, intensive, holistic and scientific rigours activities are widely in need. Besides, understanding of the complex human, animal and wider environment interplay has found the frontline strategy to mitigate antimicrobial resistance burdensome in human and animal settings.

Published: February 2023

With rising incidences of fungal infections leading to Invasive Fungal Infections (IFIs), Antifungal Susceptibility Testing (AFST) has become the need of the hour and its availability at all the tertiary care settings is a prerequisite for better diagnostics and thus, improved therapeutic management. Multiple factors are into play rendering this rising incidence, and thus, the potential antifungal resistance in those fungi is imminent. To let it off, cautious and timely measure of availing AFST and identification of fungi to species level has become mandatory and needs to be addressed. Antimicrobial Stewardship may play a major role in this transition.
