Validation of low dosages of γ-radiation and their effect on red beetle mortality, storability characteristics, and nutritional value of sorghum (Sorghum bicolor L. Moench) grain.

This research was undertaken to validate the low dosages of γ-radiation of sorghum to examine the efficiency of gamma irradiation doses in quality attributes and storability of sorghum grain. Infested sorghum grains with the red flour beetle at the adult stage were irradiated at 0.25, 0.5, 0.75, 1.0, and 2.0 kGy emitted by 60CO. Subsequently, the mortality rate of the red flour beetle as affected by gamma doses was estimated and the storability characteristics and nutritional value of sorghum grains were measured. Eventually, the Partial Least Squares regression (PLS) analysis was executed to confirm the optimum dose of gamma which eliminate the red flour beetle and enhanced the grain quality. Results provide that the storability characteristics were enhanced after treatments. However, the changes in the germination rate of the grains were not different significantly after radiation. On the other hand, the radiation process enhanced sorghum grins' nutritional quality. Both tannins and phytic acid content dropped significantly and the digestibility and solubility of protein were gradually incremented in the grains. The PLS results indicated that using 1 and 2 kGy reflect the utmost effective dosage for sorghum. It can be concluded that this method is a potent rapid and operative preservation process to the alternate smoking chemical procedure for improving sorghum's nutritional and functional quality and prolong its shelf life. Possibility of providing effective and rapid quarantine security as an alternative to chemical fumigation protocol to extend shelf life and enhance the nutritional and functional quality of sorghum.

Ostial stenosis of reimplanted left main coronary artery and supravalvular pulmonary stenosis: a case report of two complications of surgery for anomalous left coronary artery from the pulmonary artery.

Background: Anomalous origin of the coronary artery from the pulmonary artery (ALCAPA) is a rare congenital disease. Surgical re-implantation of the left main coronary artery (LMCA) to the aorta is a definitive treatment with a good prognosis. Case summary: A 9-year-old boy was admitted with a complaint of exertional chest pain and dyspnoea. At 13 months of age, he was diagnosed to have ALCAPA as a workup of severe left ventricular systolic dysfunction and underwent coronary re-implantation of ALCAPA. Coronary angiogram displayed the high takeoff of re-implanted LMCA with significant ostial stenosis, and echocardiogram showed significant supravalvular pulmonary stenosis (SVPS) with a peak gradient of 74 mmHg. After a multidisciplinary team discussion, he underwent percutaneous coronary intervention with stenting to ostial LMCA. On follow-up, he was asymptomatic and a cardiac computed tomography scan showed a patent stent in LMCA with an under-expanded area in the mid-segment. The proximal part of the LMCA stent was located very close to the stenotic segment of the main pulmonary artery making it a high risk for balloon angioplasty. The surgical intervention of SVPS is delayed to allow the somatic growth of the patient. Discussion: Percutaneous coronary intervention in re-implanted LMCA is a feasible option. If stenosis of re-implanted LMCA is accompanied by SVPS, the latter can be best treated surgically and staged to decrease the operative risk. Our case also demonstrates the importance of long-term follow-up of post-operative complications of patients with ALCAPA.

Total phenolic content in ripe date fruits (Phoenix dactylifera L.): A systematic review and meta-analysis.

Ripe date fruits contain phenolic compounds which possess a high antioxidant activity. The current review was carried out to evaluate total phenolic content in ripe date fruits. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was followed during the review process. Relevant studies published from inception up to March 2019 were retrieved from three databases. Study selection was performed based on specific inclusion criteria. A total of twenty-two articles were selected and included in the present review. Data collected from these studies were organized, pooled, and analyzed using descriptive statistics. Total phenolic content means and medians have been reported for the collected ripe date fruit samples for each included study and pooled data. The results suggested that ripe date fruits contain a potent total phenolic content that can contribute mainly to their antioxidant properties.

Inverted Sinonasal Papilloma Involving the Middle Ear with Evidence of Squamous Cell Carcinoma.

Inverted papilloma is an uncommon benign epithelial tumor that typically affects the nasal cavity and originates from the lateral sinonasal wall. Inverted papilloma occurring in the middle ear is an even more rare and aggressive condition. We describe a case of a 76-year-old man who was treated for isolated sinonasal inverted papilloma and after 20 months he was found to have a recurrence in the nasal cavity with middle ear involvement and malignant changes consistent with nonkeratinizing squamous cell carcinoma arising from inverted papilloma. Several surgical procedures were required to remove the tumor along with radiation therapy postoperatively.
