In this experiment, the exogenous application of hydrogen sulfide (H2S; 1, 2 or 3 mM) and phenylalanine (PA; 2.5, 5, or 7.5 mM) to alleviate chilling injury and enhancing antioxidant activity and membrane stability of eggplant fruits (Solanum melongena cv. Hadrian) during storage at 7℃ for 21 days was investigated. Results indicated that H2S and PA alleviated chilling injury and reduced electrolyte leakage percentage and malondialdehyde accumulation. Exogenous application of H2S and PA maintained significantly higher levels of proline, total phenols, and flavonoids. It was also found that H2S and PA reduced the hydrogen peroxide accumulation with up‐regulated activities of superoxide dismutase, catalase, and ascorbate peroxidase. These results indicated that H2S and PA alleviated chilling injury of eggplant fruit may through the enhancement of reactive oxygen species scavenging system activity, proline, and phenolic accumulation.
Practical applications
Eggplant fruits are a good source of anthocyanin, phenolic compounds, and vitamins. Low temperature storage is effective for preserving nutritional quality during storage time, however, eggplant fruits are chilling sensitive. We investigated the effect of hydrogen sulfide (H2S) and phenylalanine (PA) to alleviate chilling injury in eggplant fruits during cold storage. H2S and PA treatments ameliorated chilling injury in eggplant fruit with decreasing electrolyte leakage percentage and malondialdehyde accumulation. Eggplant fruit treated with H2S and PA exhibited higher 2, 2,‐diphenyl‐2‐picryl‐hydrazyl‐scavenging capacity resulting from enhancing enzymatic antioxidant activities and increasing proline and phenolic compound accumulation.
Background
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a virus which causes COVID-19. It binds to the angiotensin-converting enzyme 2 (ACE2) receptors, expressed in key metabolic organs and tissues, including pancreatic beta cells, adipose tissue, the small intestine, and kidneys. This condition has been linked to a variety of additional symptoms, including acute encephalopathy, changes in consciousness, and even gastrointestinal bleeding.
Case presentation
In this study, we have reported a 13-year-old boy, 69 kg, with SARS-COV-2 infection. In this case, multiple systems, including the endocrine, renal, pulmonary, gastrointestinal, and nervous systems, were affected.
Conclusions
It is speculated that different manifestations of COVID-19 can be seen in clinical settings, and practitioners should be more cautious not to miss the chimeric characteristics of COVID-19 infection.
Idiopathic short stature (ISS) is a kind of low height among children in which children's height is more than 2 standard deviation (SD) scores below the mean score of the height of other children with the same age and gender. It is one of the disorders that physicians use growth hormone for its treatment. Therefore, the purpose of the current study was to investigate the effect of growth hormone treatment on the adulthood height of children with ISS through meta-analysis method. In total 20 studies with a sample size of 1,517 were included in the meta-analysis through searching in external databases, including Web of science, Pubmed, Cochran, Medline, Embase, Springer, Scopus, and Science Direct using mesh keywords as growth hormone, final height, adult height, and idiopathic short stature. Mean score and SD were utilized for measuring any increase in height growth and random effect model was used for combining studies. Further, I 2 index was used for determining the heterogeneity of studies. Results indicated that before treatment, according to standard mean difference percentile of children's height was -1.64 (95% confidence interval (CI): -2.01 to -1.28) which is equal to 5%. After treatment, according to standard mean difference percentile of children's height came out to be 0.11 (95% CI: 0.07 -0.14) which is equal to 54.38%. This indicates that percentile of children's height has increased as a result of treatment with growth hormone. Through combining the results of all studies, the mean score for participants' height before treatment was 5% and after treatment it reached 54%. Therefore, obtained mean difference for adult height after treatment with growth hormone was reported to be more than 1.4 SD score (about 7.6 cm). Growth hormone can be influential in increasing the adult height of children with ISS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
