Lanthanium manganite (LaMnO3) is an interesting perovskite material with many practical applications in various fields. In the present work, LaxSr1-xMnO3 (x = 0.2–0.4) nanopowder was prepared by a single step microwave combustion process without any post annealing requirements. The as-prepared nanoproducts were characterized with different measurements such as X-ray diffraction, scanning electron microscopy, diffuse reflectance, Raman scattering and magneto vibrating sample. The nanoproducts of high crystal quality showed small bandgap of about 2.2 eV, which is very useful for visible photocatalytic activity. The obtained nanoparticles also possess excellent photocatalyst activity in visible light, which is demonstrated by ability to degrade up to 96% of methylene blue 10 ppm after 120 min of irradiation with visible light. Sr doped LaMnO3 nanoparticles also exhibit superparamagnetic property with high magnetization of 57 emu/g, which opens recyclable ability in water treatment application of the synthesized nanopowder.
Sexual victimization, happened during childhood and beyond, is known to be a substantial contributing factor for obesity development later in life. This work aims to bring about updated information ...on the relationship between sexual harassment and obesity.
Based on an intensive scientific literature review in Google Scholar, Pubmed databases, the total of 106 studies (N = 141,199) were assessed including 52 studies on the connection between negative lifetime impacts and obesity, 11 studies on post-traumatic stress disorder (PTSD) symptoms with proposed biological mechanisms related to obesity, 15 studies on the relationship between major depressive disorder (MDD) symptoms and obesity, 11 studies on the body dismorphic disorder (BDD) and 17 studies on the binge eating disorder (BED) were also examined to evaluate the association of obesity and traumatic life experiences.
Although 40–70% of all cases related to obesity have been considered to be hereditary, many experts argue that deviations in the environment contribute to excessive food intake and depressed physical activity in numerous Western countries. Several studies have identified that childhood sexual abuse (CSA) may be nearly as common as obesity. However, just a few researchers have taken notice of the possible connection between these two.
By mentioning some possible obesity-related psychological disorders in response to CSA, we present updated information on the relationship between sexual harassment and obesity.
•Victims of childhood sexual abuse is often connected to many mental sequelae including PTSD, MDD, BED and BDD.•These mental disorders are contributing factors for the development of obesity in victims later in life.•In LMIC countries, rigorous research towards the impacts of childhood sexual harassment should be regularly conducted.•Prevention of sexual assault is related to providing healthy, secure environments and behaviors.
Oxyurichthys is a genus of goby that is widespread in the tropical Indo-West Pacific region. Oxyurichthys species are usually found in estuarine and coastal marine habitats. In Southeast Asia, they ...are commercial fishes and often collected by trawling to serve the market's demand. The mitogenome serves as a good marker for investigating the systematics and evolution of fishes, but the mitogenome of Oxyurichthys species remains unknown. In this study, mitogenomes of two Oxyurichthys gobies, O. ophthalmonema and O. microlepis, were characterized and compared. The sizes of the mitogenomes were 16,504 bp and 16,506 bp for O. ophthalmonema and O. microlepis, respectively. Mitogenomes of these two species were similar in gene content and structure. Both included 37 genes and a control region. The two Oxyurichthys mitogenomes shared similar gene features and base composition with other recorded gobies. Typical conserved blocks (CSB-1, CSB-2, CSB-3 and CSB-D) were found in the control region of both species. Phylogenetic analyses based on concatenation of 13 protein-coding genes and 2 rRNAs revealed that the two Oxyurichthys species clustered together and were sister to species of the genera Sicydium, Sicyopterus and Stiphodon. The findings of the present study support previous evolutionary studies of gobies using other molecular markers.
To evaluate the efficiency of a biodegradable gel containing hyaluronic acid and berberine hydrochloride in endoscopic sinus surgery.
Sixty-six chronic rhinosinusitis patients with or without nasal ...polyps who underwent bilateral endoscopic sinus surgery (ESS) were randomly received a biodegradable gel containing hyaluronic acid and berberine hydrochloride or merocel in both middle meatal spacers at the end procedure of ESS. Lund–Kennedy endoscopic score (LKES) was used to examine status of nasal cavity on preoperative day and postoperative day 1 to 7. The LKES ratio was calculated as the LKES on postoperative day divided into the LKES on preoperative day. Visual analogue score (VAS) was used to assess patient's status from the first postoperative day to the hospital discharge day. The average VAS during hospital stays was calculated by the sum of VAS in each examination day divided into the number of examined day. The LKES ratio, the average of VAS during hospital stays and length of hospitalized day of the patients were used as clinical outcome indices in early stage after surgery. A general linear model adjusted for confounding factors was used for data analysis.
Adjusted mean of LKES ratio were lower in group used biodegrable gel of hyaruloic acid and berberin hydrochlode (study group) than those in merocele group in the postoperative day 1 to day 7. However, significant difference was found in the adjusted mean of LKES ratio on the postoperative day 2 to 6. Similarly, the adjusted mean of VAS during hospital stays and length of hospitalized day after surgery in study group were significantly decreased as compared with those in merocele group.
Biodegradable material containing hyaluronic acid and berberine hydrochloride was more effective than merocel in length of hospital stay, post-operative symptoms, and sinus cavity's status in early stage after ESS.
•Effects of a biodegradable gel containing hyaluronic acid and berberine hydrochloride in ESS were investigated.•The used a biodegradable gel of hyaluronic acid and berberine hydrochloride in ESS improved clinical outcome in early stage.•Long term clinical outcome of using a biodegradable gel of hyaluronic acid and berberine hydrochloride after ESS is required.
Recently, edible films and coatings have received more attention instead of plastic packaging. Pectin prepared from gac pulp, a waste generated from gac oil production, was used to prepare edible ...films combined with seaweed hydrocolloids. This study aimed to investigate the impact of sodium alginate (SA), kappa‐carrageenan (KC), and gac pulp pectin (GPP) on the physical, barrier, and mechanical properties of the resultant films. The optimum formula with the best characteristics was identified using Response Surface Methodology (RSM). Results revealed that most of the film properties were significantly influenced by seaweed hydrocolloids, while GPP significantly affected color properties. Besides, the interaction between GPP and seaweed hydrocolloids affected the water vapor permeability and mechanical properties. The optimum formula was SA of 1.28% w/v, KC of 0.58% w/v, and GPP of 0.25% w/v. The result suggests that this formula has the potential as an edible film for further applications in foods.
Novelty impact statement
A composite edible film with great physical and mechanical properties can be developed from an optimal formulation of sodium alginate, kappa‐carrageenan, and gac pulp pectin, derived from a waste of the oil production. This film is potentially applied for coating and preservation of foods to improve their properties and shelf‐life.
Background:
In middle-income countries such as Vietnam, where healthcare resources are already constrained, protecting healthcare workers (HCWs) is essential for ensuring the sustainability of ...COVID-19 response in Vietnam. This study was conducted to assess the knowledge and practices regarding the prevention of the COVID-19 among the HCWs in Vietnam to identify the ways of disseminating information to maximize the safety of these essential workers.
Methods:
An online cross-sectional study, using respondent-driven sampling, was conducted in Vietnam with 742 participants within 2 weeks. The validity of the questionnaire was examined by exploratory factor analysis. Descriptive statistics were used to identify the level of knowledge and practices among the HCWs to prevent the COVID-19. Inferential statistics and regression modeling were used to identify the associated factors with results.
Results:
Vietnamese HCWs had a high level of knowledge with more than 75% of the participants demonstrating awareness of all the modes of transmission aside from air. The mean knowledge score was 3.7 ± 0.8 (range 1–5). Nearly all the participants relied on the Ministry of Health (98.3%) and the internet (95.5%) for information regarding the COVID-19. The participants endorsed a moderately high level of self-protective practices with mean scores of 4.2 and 3.6 (band score 1–5) for the precautionary and psychological measures, respectively. Nurses were more likely to practice the precautionary measures than doctors and the HCWs at the central level were more likely to practice the psychological measures than those at the district level.
Conclusion:
Future education initiatives should consolidate the latest literature in an accessible format, focusing initially on the gaps of knowledge regarding aerosol transmission. These initiatives should primarily focus on the doctors, especially those in emergency and intensive care departments.
In a United Nations (UN) staff member headquarters in South Sudan, we present a rare typhoid fever complicated by syncope due to relative bradycardia. A 25-year-old male presented to our hospital ...with a high fever, diarrhea, and no vomiting. He had no substantial medical background. He was diagnosed with an unspecified digestive disorder and received initial treatment. Two syncope episodes were recorded in the Level 1 hospital. He was referred to our hospital at the 30th hour and the third fainting occurred. Electrocardiogram showed bradycardia with a heart rate of 40 beats/min. The atropine test was negative; the initial diagnosis was sinus sickness syndrome. Microbiology tests later suggested typhoid infection. Then, the diagnosis changed to relative bradycardia caused by Salmonella typhi; and he was orally treated with the third-generation Quinolone antibiotic. He significantly improved and got discharged on the seventh day. In conclusion, typhoid remains a real and present threat to UN staff and civilians in South Sudan.

Docking experiments indicated that the compounds tightly bound to HDAC2 at the active binding site with binding affinities much higher than that of SAHA. Our present results demonstrate that these novel hydroxamic acids are potential for further development as anticancer agents.
Jonas, 1844 is of great commercial interest, but its reserves have dramatically declined over recent decades. Therefore, there is an urgent need of scientific basis to propose effective fishery ...management measures and improve artificial aquaculture of the clam. In this study, we investigated the distribution and density of
, sediment characteristics, and established the clam’s reproductive cycle through monthly observations from August 2017 to July 2018. The study results showed that distribution and density of clams are related to sediment types, and the sediment type of medium sand is likely the best benthic substrate for the clams. The spawning of clams occurred throughout the year with three spawning peaks in January, April and September. For the sustainable management of the clam resource in Cat Ba-Ha Long Bay, the fishery authorities can issue a ban on harvest of the clam in spawning peak months in January, April and September.
