Amino acids and sugars, along with the thermal processing, are considered the main parameters to control acrylamide formation in fried potatoes. To evaluate which of these parameters had the greatest influence, 10 synthetic potato-starch-based models formulated in different amino acid and/or sugar combinations and three potato cultivars were assigned. High-performance-liquid chromatography and gas chromatography flame-ionized-detectors were applied to quantify amino acids, sugars, and acrylamide. Results showed that reducing sugars and sucrose significantly increased acrylamide formation amongst all potato samples. Synthetic potato models Asn-GFS contained the highest amount of acrylamide compared to Glu-Fru and real potatoes (Agria and Kennebec). Thus, sugars were considered critical factors for acrylamide formation in potatoes and remained the most practical way of reducing its production.

The potential benefits of pyrotinib for patients with trastuzumab-insensitive, HER2-positive early-stage breast cancer remain unclear. This prospective, multicentre, response-adapted study evaluated the efficacy and safety of adding pyrotinib to the neoadjuvant treatment of HER2-positive breast cancer patients with a poor response to initial docetaxel plus carboplatin and trastuzumab (TCbH). Early response was assessed using magnetic resonance imaging (MRI) after two cycles of treatment.

Global high consumption of fried potatoes is driven by appealing taste and edible convenience. However, the occurrence of Maillard reaction hazardous products (MRHPs) and joint control recipes have scarcely been concerned. We aim to reveal and predict how fish oil treatment for potato slices reduces simultaneous formation of typical MRHPs in air-based thermal processed potato chips.

In this paper, zein-carboxymethyl starch (CMS) nanoparticles were prepared by antisolvent precipitation method to improve the stability of rutin (RT). The encapsulation efficiency, loading capacity, oxidation resistance, structural properties were evaluated. The results showed that electrostatic, hydrogen bond and hydrophobic interaction were the main driving forces for the formation of nanoparticles.

Article Synopsis
- China's crude oil supply is heavily reliant on imports, making self-sufficiency crucial for national energy security.
- Polymer flooding, particularly with oil flooding polymers, increases oil recovery rates but presents challenges like poor thermal stability, environmental issues, and operational complications.
- The review explores biomanufacturing techniques for producing more efficient and sustainable polymers and emphasizes using microbial metabolites to enhance oil recovery, promoting greener practices in the oil industry.
Anti-Scar Effects of Micropatterned Hydrogel after Glaucoma Drainage Device Implantation.

Excessive fibrosis is the primary factor for the failure of glaucoma drainage device (GDD) implantation. Thus, strategies to suppress scar formation in GDD implantation are crucial. Although it is known that in implanted medical devices, microscale modification of the implant surface can modulate cell behavior and reduce the incidence of fibrosis, in the field of ophthalmic implants, especially the modification and effects of hydrogel micropatterns have rarely been reported.
