Article Abstract
A study was initiated with the objective of evaluating the effects of sonication treatment on important quality parameters of extract of Pinus massoniana pollen. Sonication of extract was done (frequency 20kHz and various amplitude levels) for 10, 30, 50min, respectively. As results, total polysaccharide, phenolics and flavonoids significantly increased (P<0.05). And sonicated P.massoniana pollen displays strong immuno-stimulating activity by increasing proliferations of splenic lymphocytes and subsets of CD4+ T cells (CD3+CD4+), CD8 T cells (CD3+CD8+), and increased Ig secretion. Sonicated P. massoniana pollen also showed anti-tumor function by inhibition of tumor cell proliferation, inhibition of ROS production, up-regulation of GSH/GSSG ration, up-regulating the gene expression of P53, Bax and down-regulating the gene expression of Bcl-2. Findings of the present study suggested the sonication treatment of P. massoniana pollen could improve the quality and bioactivity of P. massoniana pollen, indicating that sonication is effective in processing of pollen and could be a potential process in tumor prevention and treatment.

Purpose Of The Study: 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-β-D-mannopyranose (mannose triflate), the precursor used for the synthesis of [F] Fluorodeoxyglucose ([F] FDG) is imported from a few commercial suppliers abroad. As part of self-reliance, a reliable synthesis and characterization of mannose triflate has been developed, details of which are reported in this paper.
Materials And Methods: Synthesis of 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-β-D-mannopyranose (Mannose triflate) carried by Triflation of 1,3,4,6-Tetra-O-acetyl-β-D-mannopyranose with Tf2O-pyridine under argon atmosphere for 6 h.
Efficacy and Safety of Ramelteon in the Reduction of Delirium and Duration of ICU Stay: A Randomized Placebo-Controlled Trial.

Background Delirium and sleep disturbances are common in critically ill patients and are associated with adverse outcomes, including prolonged intensive care unit (ICU) stays. Ramelteon, a melatonin receptor agonist, may improve sleep and reduce delirium by regulating circadian rhythms. This study evaluated the efficacy of ramelteon in shortening ICU stay, decreasing delirium incidence and duration, and improving sleep quality in critically ill patients.

Background And Aim: Mycotoxin contamination in poultry feed, particularly with aflatoxin B1 (AFB1) and ochratoxin A (OTA), poses significant threats to broiler health, meat quality, and consumer safety. Toxin binders are commonly used to mitigate these effects; however, their impact on endogenous stem cell activity and overall broiler performance remains underexplored. This study aimed to evaluate the efficacy of a commercial toxin binder in reducing AFB1 and OTA residues in broiler meat, inducing endogenous stem cell production, and improving growth and feed performance indices.

Background And Aim: The () gene is recognized as a critical regulator of ovarian function and fertility in cattle. However, its role in crossbred populations, particularly Madrasin cattle (Madura × Simmental cross), remains underexplored. Understanding the genetic underpinnings of fertility traits in this crossbreed could provide valuable insights for improving reproductive efficiency in Indonesia's livestock sector.
