Marfan syndrome is a dominant autosomal genetic disease of the connective tissue, leading to various complications. Cardiovascular complications are the main ones, with dilation of the aorta and aortic dissection which is the main cause of death. Double dissection with different sites of departure is scarcely reported by the literature. We reported the case of a 22-year’s-old young patient admitted for acute chest and abdominal pains, and cardiogenic shock. Investigations reported a double dissection of the aorta with a recent one of type A and an old one of type B. Ghent diagnostic criteria were used to allow the diagnosis of Marfan disease. Surgical management corrected successfully the type A dissection.Early diagnostic and adequate management of aortic complications can reduce the high mortality rate of patients with Marfan syndrome.

Due to the adverse environmental impacts of synthetic plastics, biodegradable plastics development for both industrial and commercial applications is essential for the present scenario. In addition to the non-degradability of petroleum-based plastic and its impacts, so it is very important to find an alternative to petroleum-based plastic. Starch-based bioplastics are an excessive substitute for petroleum-based plastics due to their significant properties compared with natural sources. This research aims to formalize five new formulas of bioplastic by combining two sources of starch, extracted from various biomass sources, its properties and comparison between them. The moisture content shows 2.07% and 0.984% for samples F and B respectively and that indicates that the samples which contain a high amount of corn starch have less moisture content. The highest results of biodegradation percentages were 68.27% and 52.6% which are for samples A and D respectively, and the lowest biodegradation percentage were 34.33% and 31.29% which are for samples F and B respectively.

Although emotion management is essential to mental health, public health has not paid much attention to emotional conditions or disorders. By analyzing a nine-year diagnostic trend and sociodemographic characteristics of two mental disorders: Hwabyung and Intermittent Explosive Disorder (IED), this study demonstrated the importance of managing emotions precautionarily.Data reconstructed from the National Health Insurance Service were used to analyze the yearly diagnostic trend in the two mental disorders characterized by anger.Hwabyung was more common among women and middle-aged individuals, despite the varied number of diagnoses by year. Between 2010 and 2018, IED diagnoses gradually rose, with the average rate of increase the highest in the 20s for male IED diagnoses in 2017. The low prevalence of the IED in Korea compared to other Western countries and the gender and age differences in both Hwabyung and IED diagnoses suggest the role of cultural influences related to emotions (or emotional management).Especially in light of the world’s emphasis on resilience to COVID-19, these results indicate how public emotional management is essential during stressful situations. The results also highlight the need for community mental health programs tailored to gender and age.

Context: Illicit and performance-enhancing drug (PED) use is prevalent among athletes.Aims: We examine the prevalence of PED use among amateur athletes, identify the common characteristics and associated risk factors for illicit PED use and measure the perception and awareness among gym members regarding the safety and effects of illicit drug use.Settings and design: This cross-sectional study was conducted among adult male and female gym center attendees in Riyadh, Saudi Arabia.Methods and materials: Self-administered Arabic and English questionnaires were used for data collection. Statistical analysis used: SPSS version 26 was used to perform t- and chi-square tests.Results: This study included 379 participants, of whom 59.6% were male, 52.8% were between 26 and 35 years of age, and a majority of the participants had normal (47.5%) or overweight (40.9%) body mass index. Our study revealed a high prevalence (48.5%) of PED use among gym athletes in Riyadh, Saudi Arabia. Moreover, the true prevalence might have been higher due to the possibility of underreporting by some participants because of the sensitivity of the subject. Protein powder was the most commonly used type of PED. Of all the participants, 22.3% reported anabolic androgenic steroid use. Side effects of PEDs were observed in 19% of the study participants.Conclusion: The results of this study should encourage public health researchers and health advocates to design and implement behavioral interventions to educate the public on the benefits, risks, and contraindications of dietary supplements used by athletes to enhance their body performance.Key messages•    Performance-enhancing drug (PED) use is prevalent among both professional and amateur athletes.•    Gym athletes in Riyadh, Saudi Arabia, report increasing PED use.•    Side effects and negative health impacts are associated with illicit PED use.•    Misinformation on the risks and benefits of PEDs is a major public health concern.•    More efforts should be implemented in public awareness about the risk of using PED targeting younger populations.

Fragaria vesca L. (Rosaceae), called “wild strawberry”, “woodland strawberry”, “Alpine strawberry”, “Carpathian strawberry” or “European strawberry” is grown naturally throughout much of the Northern Hemisphere and produces fruits. The plant can be spread mostly by stolons as well as by the seeds to establish new populations.

Background: Parapneumonic pleural effusion is a relatively common entity and continues to be a major cause of morbidity in children. However, managing this disease is still a matter of controversy between surgical and non-surgical options. With the advancement of mini-invasive surgery, video-assisted thoracoscopic surgery (VATS) has become a mainstay in the treatment of parapneumonic effusion in children. This study aimed to evaluate the clinical characteristics and pathological features of parapneumonic pleural effusion in children and to explore the feasibility and safety of the thoracoscopic approach in the pediatric population.Methods: The clinical data of all patients who underwent VATS for parapneumonic effusion between 2007 and 2021 were analyzed retrospectively. Factors that were documented included demographic criteria, clinical manifestations, preoperative examinations, therapeutic procedures, intraoperative findings, postoperative complications, and outcomes.Results: Totally, 35 patients with a mean age of 5.14 ± 3.9 years were operated on thoracoscopically. The mean duration of evolution before VATS was 9 days ± 4. All children were hospitalized in a Pediatric Continuing Care Unit. Antibiotic therapy was administrated in combination in all cases. Corticosteroid therapy was used in 2 patients. Thoracentesis was performed in 6 patients. Thoracostomy tube drainage was placed before surgery in 11 patients. The average duration of drainage before VATS was 6 days ± 4. VATS decortication and/or debridement was indicated as second-line in 23 patients. The average duration of the surgery was 51 minutes (20 min - 115 min). There is no conversion to open surgery and no intraoperative procedure-dependent complication. 4 children have early complications after the VATS and one patient had a late postoperative complication. There were no deaths during the hospital stay or follow-up. Conclusion: In skilled hands, VATS is safe, feasible, and effective in the management of parapneumonic pleural effusion in children with excellent outcomes.

Clustered regularly interspaced short palindromic repeat (CRISPR), a potent gene-editing tool was found in 2012. CRISPR is a genetic engineering technique that enables genome editing in living creatures and is based on the bacterial CRISPR-Cas9 antiviral defense mechanism. It is simpler, less expensive, and more accurate than previous gene editing techniques. It also has a wide range of valuable uses, including improving crops and treating genetic diseases. Plant science has benefited more from the CRISPR/Cas9 editing technique than medical science. CRISPR/Cas9 has been used in a range of crop-related research and development domains, including disease resistance, plant development, abiotic tolerance, morphological development, secondary metabolism, and fiber creation, as a well-developed cutting-edge biotechnology technique. This paper summarized the role of the CRISPR-CAS9 tool in modern agricultural science.

In Ghana, there is evidence of the direct influence of climate change on the environment, such as rising temperatures, variable rainfall, and precipitation. These manifestations affect various facets of Ghana socio-economic structure especially with its high reliance on sectors that are particularly sensitive to climate change like agriculture. In the settlements of Bonsua and Amoawi in the Offinso South District, the study concentrated on the influence of climate change variables on food crop production and how farmers are adapting to the various climate change measures. Out of the total of 650 staple food crop farmers in the dorminated selected communities namely, Amoawi and Bonsua, 160 farmers were chosen for the study using systematic random sampling. The study included both primary and secondary data. Descriptive cross sectional survey was employed for the study. The data collection instrument employed was Structured and semi-structured interviews. SPSS was used to analyse the data. The data collected for the study were analysed using both descriptive and inferential analytical tools. Findings from the study indicate that climate change is a challenge to food crop production since agriculture activity in the two communities are mostly rain feed (97.5%). The majority of the crops grown in the two areas are climate change vulnerable. Another study finding reveals that most respondents have modified their coping mechanisms such as such as growing different crop varieties, early and late planting, irrigation and soil conservation to deal with how climate change is affecting agriculture. Therefore, the study suggests that both government and non-governmental organizations should support farmers in building irrigation systems to continuously irrigate their food crops during the dry season, increasing their farm productivity.

Saliva is produced by and secreted from salivary glands. It is an extra-cellular fluid, 98% water, plus electrolytes, mucus, white blood cells, epithelial cells, enzymes, and anti-microbial agents. Saliva serves a critical role in the maintenance of oral, dental, and general health and well-being. Hence, alteration(s) in the amount/quantity and/or quality of secreted saliva may induce the development of several oro-dental variations, thereby the negatively-impacting overall quality of life. Diverse factors may affect the process of saliva production and quantity/quality of secretion, including medications, systemic or local pathologies and/or reversible/irreversible damage. Herein, chemo- and/or radio-therapy, particularly, in cases of head and neck cancer, for example, are well-documented to induce serious damage and dysfunction to the radio-sensitive salivary gland tissue, resulting in hypo-salivation, xerostomia (dry mouth) as well as numerous other adverse Intra-/extra-oral, medical and quality-of-life issues. Indeed, radio-therapy inevitably causes damage to the normal head and neck tissues including nerve structures (brain stem, spinal cord, and brachial plexus), mucous membranes, and swallowing muscles. Current commercially-available remedies as well as therapeutic interventions provide only temporary symptom relief, hence, do not address irreversible glandular damage. Further, despite salivary gland-sparing techniques and modified dosing strategies, long-term hypo-function remains a significant problem. Although a single governing mechanism of radiation-induced salivary gland tissue damage and dysfunction has not been yet elucidated, the potential for synergy in radio-protection (mainly, and possibly -reparation) via a combinatorial approach of mechanistically distinct strategies, has been suggested and explored over the years. This is, undoubtfully, in parallel to the ongoing efforts in improving the precision, safety, delivery, and efficacy of clinical radiotherapy protocols/outcomes, and in designing, developing, evaluating and optimizing (for translation) new artificial intelligence, technological and bio-pharmaceutical alternatives, topics covered in this review.

Azotobacter was selectively isolated and purified from the soil samples of Xinjiang Salt Lake Scenic spot, the fermentation technology of exopolysaccharides (EPS) by Azotobacter was optimized, and the antioxidant activity of exopolysaccharides (EPS) was studied. The bacteria were isolated and purified from the soil samples by the scribing method and the 16SrRNA gene was used for molecular identification. The carbon source, fermentation time, inoculation amount and pH of target bacteria in the exopolysaccharides (EPS) fermentation process were optimized through single-factor experiments and their antioxidant activity was measured. Eight types of Azotobacter were isolated and purified from the soil samples of Salt Lake scenic spot. Among them, As101, which showed 99.58% homology with Azotobacter salinestris, was selected as the target strain. Through single-factor experiments which used exopolysaccharides (EPS) yield and exopolysaccharides content as indexes, the optimal conditions for the As101 fermentation process were determined as follows: fermentation temperature 35, fermentation time 96h, pH 7 and mannitol as carbon source. Exopolysaccharides content from Azotobacter salinestris  was 61.35% and the yield was 6.34 g/L. The results of the exopolysaccharides (EPS) antioxidant activity experiment under optimal conditions showed that As101 EPS had excellent scavenging ability against DPPH free radical, ABTS free radical and hydroxyl free radical, with IC50 values of 6.11 mg/ml, 2.42 mg/ml and 9.57 mg/ml, respectively. As101 with high yield and high exopolysaccharides content was isolated from saline soil in a special environment of Xinjiang, and the EPS obtained showed excellent antioxidant activity. The Azotobacter found in this study would provide the material basis for further opening up the adsorption of exopolysaccharides on heavy metals and the improvement of saline-alkali soil and contribute to further understanding of the structure and other activities of exopolysaccharides derived from Azotobacter.
