In vitro conditions

Circulating tumor cell (CTC) clusters play a critical role in carcinoma metastasis. However, the rarity of CTC clusters and the limitations of capture techniques have retarded the research progress. In vitro CTC clusters model can help to further understand the biological properties of CTC clusters and their clinical significance.

In this study, the effect of plant growth regulators (BA and NAA), ripe bananas in combination with potato, humic acid, and silver nanoparticles (AgNPs) were investigated to find a suitable condition for in vitro plant regeneration from R. imschootiana protocorm-like body (PLB). The results showed that after 45 days of culture, MS medium supplemented with 100 g ripe banana/liter and 100 g potato/liter was suitable for regenerating shoots from the protocorm-like body (PLB) (17.56 shoots/PLBs and 100.00% of shoot-regenerating PLBs).

A series of chalcone analogues were synthesized using Claisen-Schmidt condensation and assayed for in vitro inhibitory activity against α-glucosidase. The synthesis involved in solvent-free reaction conditions including NaOHcatalyzed grinding or microwave irradiation in the presence of a clay-based catalyst. Hydroxychalcones and 2′-hydroxychalcones were not isolated when using grinding method, while the microwave-assisted, clay-catalyzed synthesis gave these desired products. In addition, flavanones, cyclization products from 2′-hydroxychalcones were formed in both methods.

Ebook "Percutaneous absorption of UV filters contained in sunscreen cosmetic products: Development of analytical methods" describes the development and validation of analytical methods to estimate the processes set in motion by percutaneous absorption of UV filters in sunscreen cosmetic products. León describes these methods in both in vitro and non-invasive in vivo methodologies. Currently dermatologists recommend the use of sunscreen products not only under conditions of extreme exposure to the sun but also in daily situations.

We investigated the effects of somatostatin on the ileal movements after gravity stress and compared these effects between male and female rats. Using an in vitro preparation, measurements of ileal movements evoked by somatostatin application were done at 1, 3, 15 and 30 days after 3G gravity loading-conditioning.

Current chemotherapies can often kill fast-growing cancer cells but are ineffective in destroying cancer stem cells (CSCs). This study aimed to investigate the effect of in vitro cell culture conditions on the features of lung adenocarcinoma cells (represented by A549, non-small cell type (NSCLC), cell lines) and the induction of cancer stem-like cells.

Pseudorabies (PR) is latent and can persist in infected sows for a long time, and thus, convalescent sows can carry the virus throughout life, causing severe economic losses to farmers and posing a tremendous challenge to PR prevention and control. Here, to investigate the biological characteristics of pseudorabies virus (PRV), a variety of physical and chemical factors were analyzed under controlled conditions.
