Electro-responsive Molecularly Imprinted Polymers (E-MIPs) for Rapid Detection of Progesterone in Human Serum Samples.

Rapid and reagent-free detection of progesterone (P4) is crucial in point-of-care (POC) measurement due to its important role in the human endocrine and central nervous system. Currently available technologies for P4 detection are often not rapid or require reagents, limiting their use in POC settings. In this work, a self-signaling electrochemical sensing platform for rapid detection of P4 is developed by using electroactive molecularly imprinted polymers (E-MIPs).

Viral reprogramming by nervous necrosis virus alters key metabolites and its pathways in sevenband grouper (Hyporthodus septemfasciatus) gills.

Nervous necrosis virus (NNV) which mainly infects sevenband grouper (Hyporthodus Septemfasciatus) is considered a potential threat to the grouper aquaculture industry. The gills being one of the portal of entry and an active site of replication of fish viruses emphasises its role as a key region to study the metabolomic changes caused by viral reprograming and hijacking of metabolic pathways associated with immunity of the host. In the present study, liquid chromatography mass spectrometry (LC-MS) was used to detect changes of endogenous compounds of the grouper after NNV infection.

Variation in oxidative potential of fine particulate matter and its association with chemical constituents at a regional site in India.

Fine particulate matter (PM) constituents are greatly affected by site-specific emission sources and are one of the main reasons for oxidative stress that leads to cardiovascular ailments. This study investigated the temporal, seasonal, and episodic variations in the oxidative potential (OP) of PM and its association with chemical components. Additionally, we have also examined the effect of filter substrates on OP.

Synergy of histone acetyltransferase inhibitor (HATi) with quercetin inhibits biofilm formation in Candida tropicalis.

Histone acetyltransferase inhibitors (HATi) are mechanism-based inhibitors that show promise in the treatment of several illnesses, including diabetes, hyperlipidemia, cancer, and Alzheimer's disease. The work emphasizes the significance of HATi as a possible treatment strategy against Candida species biofilms. Here, in this study, we found that combining a HATi, anacardic acid (AA), and quercetin, a known flavonoid, significantly prevented biofilm formation by C.

Sulfonyl-acetohydrazide derivatives as juvenile hormone mimics to be insect growth regulators.

The need for targeted pest control strategies has led to the development of juvenile hormone (JH) mimics that selectively disrupt the life cycles of harmful insect species. Present study focuses on the synthesis, characterization and evaluation of sulfonyl-acetohydrazide derivatives (H1-H8) as novel JH mimics on two different insect species, with an emphasis on their insect-specific action. The yellow fever mosquito, Aedes aegypti and cabbage leaf borer, Spodoptera litura, were selected for this investigation.

A thiourea-bridged Tc(CO)-dipicolylamine-2-nitroimidazole complex for targeting tumor hypoxia: Utilizing metabolizable thiourea-bridge to improve pharmacokinetics.

The 2-nitroimidazole based Tc-radiopharmaceuticals are widely explored for imaging tumor hypoxia. Radiopharmaceuticals for targeting hypoxia are often lipophilic and therefore, show significant uptake in liver and other vital organs. In this context, lipophilic radiopharmaceuticals with design features enabling faster clearance from liver may be more desirable.

Antioxidants in mitigating phthalate-induced male reproductive toxicity: A comprehensive review.

Phthalates, widely used as plasticizers, have been increasingly linked to male reproductive toxicity through mechanisms including oxidative stress, endocrine disruption, inflammation, and apoptosis. This comprehensive review evaluates the protective role of various antioxidants in mitigating the detrimental effects of phthalates such as di-(2-ethylhexyl) phthalate (DEHP), di-butyl phthalate (DBP), mono-(2-ethylhexyl) phthalate (MEHP), and monobutyl phthalate (MBP) on male reproductive health. Antioxidants such as lycopene, ellagic acid, genistein, and selenium compounds exhibit significant efficacy in counteracting phthalate-induced damage by neutralizing reactive oxygen species (ROS), enhancing endogenous antioxidant defenses, reducing inflammatory responses, and preventing apoptosis.

Lipophilic derivatives of EGCG as potent α-amylase and α-glucosidase inhibitors ameliorating oxidative stress and inflammation.

Uncontrolled hyperglycemia leads to increased oxidative stress, chronic inflammation, and insulin resistance, rendering diabetes management harder to accomplish. To tackle these myriads of challenges, researchers strive to explore innovative multifaceted treatment strategies, including inhibiting carbohydrate hydrolases. Herein, we report alkyl-ether EGCG derivatives as potent α-amylase and α-glucosidase inhibitors that could simultaneously ameliorate oxidative stress and inflammation.

Chemistry and ionization of HPMCAS influences the dissolution and solution-mediated crystallization of posaconazole amorphous solid dispersions.

Hydroxypropyl methyl cellulose acetate succinate (HPMCAS) is one of the polymers of choice in formulating amorphous solid dispersions (ASDs) and helps to sustain high levels of drug supersaturation by delaying drug crystallization. Herein, the impact of HPMCAS chemistry on the solution crystallization kinetics of a fast-crystallizing lipophilic drug, posaconazole (PCZ), from the aqueous bulk phase and the drug-rich phase generated by liquid-liquid phase separation (LLPS), was studied. Three grades of HPMCAS: L, M, and H, which differ in the degree of acetyl and succinoyl substitution (A/S ratio), were compared.

Is long-term administration of PLD-pegylated liposomal doxorubicin able to induce oral cancer?

Leukoplakia, a potentially malignant oral condition, manifests as a nonremovable white lesion that is often linked to risk factors such as smoking, alcohol, and HPV. Pegylated liposomal doxorubicin (PLD), which is used in cancer treatment, has been associated with secondary oral cancers, particularly in patients with leukoplakia. A case study revealed the development of squamous cell carcinoma (SCC) on the tongue following PLD treatment, suggesting a potential link between the drug and malignant transformation.

Concomitant Delivery of Pirarubicin and Salinomycin Synergistically Enhanced the Efficacy of Cancer Therapy and Reduced the Risk of Cancer Relapse.

Pirarubicin attracted considerable attention in clinical studies because of its high therapeutic efficacy and reduced toxicity in comparison with other anthracyclines. Nevertheless, ~ 30% patients undergoing PIRA treatment still experience relapse and metastasis. Clinical advancements unveiled that cancer stem cells (CSCs) residing in the tumor constitutes a major factor for such limitations and subsequently are the reason for treatment failure.
