Success rate of current human-derived gastric cancer organoids establishment and influencing factors: A systematic review and meta-analysis.

Background: Human-derived gastric cancer organoids (GCOs) are widely used in gastric cancer research; however, the culture success rate is generally low.

Aim: To explore the potential influencing factors, and the literature on successful culture rates of GCOs was reviewed using meta-analysis.

Methods: PubMed, Web of Science, and EMBASE were searched for studies.

Economic Growth, Income Inequality and Food Safety Risk.

Food safety risk, as an implicit cost of social and economic development, endangers the health of global residents, including China. To systematically understand the impact of socioeconomic development on food safety risk and to establish a sound modern governance system of food safety in China, this paper uses provincial panel data from 2011 to 2020 to explore the relationship between food safety risk and socio-economic development factors such as economic growth and income inequality by employing a two-way fixed effect model and moderating effect model. The results show that the food safety risk is a Kuznets curve, and the turning point is about RMB 58,104.

[Clinical effect of propranolol in the treatment of respiratory hemangioma in infants and young children].

Objective: To study the clinical effect of oral propranolol in the treatment of respiratory hemangioma in infants and young children.

Methods: A retrospective analysis was performed from the chart review data of children with respiratory hemangioma treated by oral propranolol and diagnosed by bronchoscopy and laryngeal plain enhanced CT/MRI from November 2012 to December 2019.

Results: A total of 20 children were enrolled.

Appendiceal mucocele: A diagnostic dilemma in differentiating malignant from benign lesions with CT.

Objective: The purpose of this study was to assess the feasibility of using CT to differentiate malignant from benign lesions in patients with pathologically confirmed appendiceal mucoceles.

Materials And Methods: CT scans of 18 consecutively registered patients (11 men, seven women; age range, 21-78 years) with pathologically confirmed appendiceal mucocele were reviewed retrospectively. Patients were classified into three groups according to pathologic results: nonneoplastic mucocele (n = 3), mucinous cystadenoma (n = 10), and mucinous cystadenocarcinoma (n = 5).

Development of a novel approach towards predicting the milling behaviour of pharmaceutical powders.

A novel approach has been developed for evaluating the milling behaviour of pharmaceutical powders based on their material and mechanical properties obtained by single particle impact testing. Milling behaviour of two widely used pharmaceutical excipients, namely microcrystalline cellulose and alpha-lactose monohydrate has been analysed in an oscillatory single ball mill. It is found that the milling behaviour of these two powders can be described by analogy with a first-order rate process except for alphaLM at 18Hz of milling frequency.
