A systematic search of the Summary of Product Characteristics (SmPC) database was conducted for 108 analgesics and antipyretics containing paracetamol, 85 NSAIDs containing ibuprofen, and 115 antiasthmatic and bronchodilator medicinal products. The study found significant associations between pharmacotherapeutic groups and the presence of these allergens (p < 0.001). Gluten was more prevalent in the group of analgesics and antipyretics (44.4%) than in NSAIDs (8.2%), whereas soy-derived excipients were more frequent in NSAIDs (14%) than in analgesics and antipyretics (6.5%). No excipients containing gluten or soy were identified in antiasthmatic and bronchodilator medicinal products. In analgesics and antipyretics, 51.2% of solid oral dosage forms and 40% of liquid oral formulations contained gluten. Within the NSAIDs group, gluten was mainly present in liquid oral dosage forms (26.7%). Soy-derived excipients were found in 30% of liquid oral formulations and in 33.3% of rectal dosage forms of analgesics and antipyretics. In the NSAIDs group, soy was more prevalent in liquid oral formulations (26.7%). These findings highlight the need for clearer labeling of allergens in medicinal products and underscore the importance of vigilance for patients with gluten or soy allergies.

An important aspect of many of these algorithms is the existence of a quantum oracle, which needs to be implemented efficiently in order to realize the claimed advantages in practice. A quantum random access memory (QRAM) is a promising architecture for realizing these oracles. In this paper we develop a new design for QRAM and implement it with Clifford+T circuit. We focus on optimizing the T-count and T-depth since non-Clifford gates are the most expensive to implement fault-tolerantly in most error correction schemes. Integral to our design is a polynomial encoding of bit strings and so we refer to this design as [Formula: see text]. Compared to the previous state-of-the-art bucket brigade architecture for QRAM, we achieve an exponential improvement in T-depth, while reducing T-count and keeping the qubit-count same. Specifically, if N is the number of memory locations to be queried, then [Formula: see text] has T-depth [Formula: see text], T-count [Formula: see text] and uses O(N) logical qubits, while the bucket brigade circuit has T-depth [Formula: see text], T-count O(N) and uses O(N) qubits. Combining two [Formula: see text] we design a quantum look-up-table, [Formula: see text], that has T-depth [Formula: see text], T-count [Formula: see text] and qubit count [Formula: see text]. A quantum look-up table (qLUT) or quantum read-only memory (QROM) has restricted functionality than a QRAM. For example, it cannot write into a memory location and the circuit needs to be compiled each time the contents of the memory change. The previous state-of-the-art CSWAP architecture has T-depth [Formula: see text], T-count [Formula: see text] and qubit count [Formula: see text]. Thus we achieve a double exponential improvement in T-depth while keeping the T-count and qubit-count asymptotically same.

BPA exposure for 14 days induced oxidative stress, evidenced by elevated malondialdehyde levels and decreased activities of antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). Higher doses of PCA effectively mitigated these effects by restoring redox balance and enhancing antioxidant enzyme activities. Additionally, BPA disrupted inflammation and apoptosis pathways, inhibiting anti-inflammatory markers and interfering with the nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1) pathway. PCA exhibited dose-dependent protection against these disruptions. Computational analyses revealed that BPA inhibits cyclooxygenase-1 through stable hydrogen bonding with threonine at position 322. PCA's dual protective effect was confirmed by attenuating inflammatory pathways, including TNF-α inhibition and suppression of the Kelch-like ECH-associated protein 1 (KEAP1) and Nrf2 signaling pathway.
