Published: January 1967

In this paper we discuss a technique for calculating moments of polydisperse materials in terms of concentration readings along the cell. The proposed method minimizes dependence on data from the end points where they may be unreliable. An analysis is given of the errors involved in the use of the proposed method when the underlying molecular weight distribution is the Schulz distribution or the lognormal.

Oncolytic therapy, inducing cell death via cell membrane lysis, holds considerable promise in cancer treatment. However, achieving precise control over the structure and function of oncolytic materials for highly selective oncolytic therapy is a key challenge in the context of the subtle differences between tumor and normal tissues/cells. Herein, we report the development of pH-ultrasensitive oncolytic polyesters (pOPs) with an alternating sequence of ionizable and hydrophobic groups.

Transition metals are a type of metal with high chemical activity and play critical roles in plant growth and development, reproduction and environmental adaptation, as well as for human health. However, the acquisition, transportation and storage of these metals always pose specific challenges due to their nature of high reactivity and poor solubility. In addition, distinct yet interconnected apoplastic and symplastic diffusion barriers impede their movement throughout the plants.

Background: Cisplatin (DDP) resistance has long posed a challenge in the clinical treatment of lung cancer (LC). Insulin-like growth factor 2 binding protein 2 (IGF2BP2) has been identified as an oncogenic factor in LC, whereas its specific role in DDP resistance in LC remains unclear.

Results: In this study, we investigated the role of IGF2BP2 on DDP resistance in DDP-resistant A549 cells (A549/DDP) in vitro and in a DDP-resistant lung tumor-bearing mouse model in vivo.

Background: Nonalcoholic fatty liver disease (NAFLD) has developed as a leading public wellness challenge as a result of changes in dietary patterns. Unfortunately, there is still a lack of effective pharmacotherapy methods for NAFLD. Wang's empirical formula (WSF) has demonstrated considerable clinical efficacy in treating metabolic disorders for years.
