RESUMO

Resistance to antibiotics is on the rise, and its indiscriminate usage has resulted in human and animal management constraints. In the research for an innovative treatment to diminish antimicrobial resistance, lactic acid bacteria (LAB) throw light on diminishing this problem in public health. As a result, this paper looked at the efficacy of LAB isolates and their active metabolites to combat pathogens, reduce antibiotic use in clinical settings, and explore the anticancer potential of 8 strains of LAB isolated from dairy products. Antifungal and antibacterial potential of LAB isolates against selected crop pathogenic fungi and food pathogenic bacteria had been estimated. Results revealed that all isolates exert antioxidant efficacy relating to DPPH, NO scavenging ability, reducing power, superoxide anion, hydroxyl radical, and anti-lipid peroxidation potential. Additionally, 12B isolate exert the highest anticancer upshot with IC50 values of 43.98 ± 0.4; 36.7 ± 0.6, 43.1 ± 0.8, and 35.1 ± 0.3 µg/ml, versus Caco-2, MCF-7, HepG-2, and PC3 cell lines respectively, whereas 13B isolate significantly had the highest selectivity index between peripheral blood mononuclear cells (PBMCs) and the tested human cancer cell lines compared to 5-fluorouracil. 13B was the most apoptosis-dependent death inducer for all human cancer cell lines besides exerting the lowest percentage of apoptosis against PBMCs suggesting its safety against PBMCs. The most promising strains 12B and 13B were identified by 16S rRNA sequencing as Lactiplantibacillus plantarum ESSG1 (MZ683194.1) and Lactiplantibacillus pentosus ESSG2 (MZ683195.1). LAB and their extracts are superb substitutive, safe, and efficient antimicrobial, antioxidant, and antitumor curative agents.

RESUMO

OBJECTIVES: The aim of the current study was to compare the physicochemical and disintegrant properties of pearl millet starch with other starches using paracetamol as model drug. METHODOLOGY: Determination of percentage yield, Physicochemical, micrometrics characteristics of starch/granules, drug excipients compatibility studies and evaluation of prepared paracetamol tablets were measured using official techniques. RESULTS: The yield of the millet starch ranged from 30 to 40%. Moisture content 8.77%, pH 5.7, Swelling capacity 1.2, Hydration capacity 1.748, Moisture uptake 11.8%, Amylose 24.6%, with poor flowability and compressibility. No significant difference in hardness, friability% & disintegration times for formulations containing millet starch to that containing potato and maize starch (P>0.05). CONCLUSION: From the study, Millet seeds locally cultivated in Sudan gave a high yield of starch, has same physicochemical properties as maize and potato starch so can be used as an alternative to those starches.

RESUMO

Despite the feminization of dentistry in many areas of the world, female representation in the field of oral and maxillofacial surgery (OMFS) is poor. The purpose of this study was to identify factors perceived by female oral and maxillofacial surgeons in Egypt, Jordan, and Saudi Arabia as being obstacles to their career progression and to compare them to factors identified by their male colleagues. This was a cross-sectional questionnaire-based study. A Google Forms questionnaire was designed to collect data on socio-demographics and perceived career obstacles in OMFS. This was distributed to oral and maxillofacial surgeons in Egypt, Jordan, and Saudi Arabia. Statistically significant differences between the genders were evident in terms of marital status (P=0.001), spouse's education (P=0.005), and spouse's occupation (P<0.001). When compared to male surgeons, female surgeons more often considered that their spouse's occupation hindered their career progression (P<0.001). Female surgeons, but not male surgeons, perceived sexism and social factors such as marriage, children, and the attitudes of society to be major career obstacles (P<0.005). In conclusion, female maxillofacial surgeons in some Middle Eastern countries were found to have different socio-demographic characteristics compared to their male colleagues and they considered sexism, marriage, children, and the attitudes of society to be major career obstacles.

RESUMO

The use of Monte Carlo simulations in diagnostic medical imaging research is widespread due to its flexibility and ability to estimate quantities that are challenging to measure empirically. However, any new Monte Carlo simulation code needs to be validated before it can be used reliably. The type and degree of validation required depends on the goals of the research project, but, typically, such validation involves either comparison of simulation results to physical measurements or to previously published results obtained with established Monte Carlo codes. The former is complicated due to nuances of experimental conditions and uncertainty, while the latter is challenging due to typical graphical presentation and lack of simulation details in previous publications. In addition, entering the field of Monte Carlo simulations in general involves a steep learning curve. It is not a simple task to learn how to program and interpret a Monte Carlo simulation, even when using one of the publicly available code packages. This Task Group report provides a common reference for benchmarking Monte Carlo simulations across a range of Monte Carlo codes and simulation scenarios. In the report, all simulation conditions are provided for six different Monte Carlo simulation cases that involve common x-ray based imaging research areas. The results obtained for the six cases using four publicly available Monte Carlo software packages are included in tabular form. In addition to a full description of all simulation conditions and results, a discussion and comparison of results among the Monte Carlo packages and the lessons learned during the compilation of these results are included. This abridged version of the report includes only an introductory description of the six cases and a brief example of the results of one of the cases. This work provides an investigator the necessary information to benchmark his/her Monte Carlo simulation software against the reference cases included here before performing his/her own novel research. In addition, an investigator entering the field of Monte Carlo simulations can use these descriptions and results as a self-teaching tool to ensure that he/she is able to perform a specific simulation correctly. Finally, educators can assign these cases as learning projects as part of course objectives or training programs.

RESUMO

OBJECTIVE: To investigate the effect of three postoperative dressings on orthopaedic wound healing. METHOD: Three hundred orthopaedic patients were divided into three treatment groups and allocated to management with one of three dressings: Primapore, Tegaderm with pad, and OpSite Post-Op. Staff completed a questionnaire to evaluate the wound progression. Outcome measures were the presence of infection, blistering and the number of dressing changes required. RESULTS: There was a significantly lower incidence of blistering with OpSite Post-Op (6%) than Tegaderm with pad (16%) and Primapore (24%) (p<0.001). Patients in the OpSite Post-Op group had the lowest exudate levels. CONCLUSION: Dressings that employ a clear film and have a high moisture vapour transmission rate have been shown to reduce both the rate of blistering and wound discharge. The additional expense inherent in using such dressings may, in reality, prove cost-effective because of the reduced need for dressings changes and the subsequent earlier discharge of these patients from hospital with an uncomplicated wound.
