Bupirimate (BPM) is a high-efficiency and low-toxicity fungicide used to combat powdery mildew in crops. To mitigate potential health risks to consumers resulting from improper BPM usage, we prepared a monoclonal antibody against BPM based on novel hapten synthesis, which has high sensitivity and strong specificity, and then successfully designed a colloidal gold-based immunochromatographic (ICG) strip. The newly designed ICG strip was then employed for detecting BPM residues in peach, orange, and carrot. The results show that for the peach, orange, and carrot samples, the calculated detection limits of the ICG strip are 9.36, 0.79, and 0.57 ng/g, respectively, and that it is resistant to the matrix effect and meets the maximum residue limit requirements of European Commission for BPM. Therefore, this developed ICG strip is expected to enable swift detection of BPM residues on the spot.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

The present work describes the synthesis of new terpyridine (tpy) molecules possessing functionalized long alkyl chains at the 4'-position associated with a planar structure with considerable delocalization. Out of the three synthesized tpy derivatives (L1, L2, and L3), L2 containing an ester group at the end of the alkyl chain emerged as an excellent probe for the selective detection of Zn. The detection of Zn ions under biological conditions was achieved by the introduction of a distinct aliphatic undecanoic ester chain at the 4'-position of the core terpyridine ring, thereby making it more lipophilic.
