Objective: The main of this study was to show the rapidity of the protoscolicide action of a synthetic compound, dipeptide methyl ester when it is injected under echographic control into hydatid cyst of sheep.
Materials And Methods: Fourthty sheep with hydatid cysts, repaired at echography and punctionable are treated by dipeptide methyl ester injection at the dose of 110 mM.
Results: In vitro tests have allowed to define the efficacy dose of dipeptide methyl ester which is 110 mM. At echography, after injection of the drug, from the first minutes, a detachment of the inner membrane, a diminution of the size of the treated cyst were observed. The cyst content is modified. The sheep autopsy was realized after 4.6.12 and 17 weeks after the injection and showed a size reduction, a treated cyst calcification.
Conclusion: The dipeptide methyl ester injection into hydatid cyst induces rapidly a morphological alteration, they are calcified. The advantage of this compound is its very rapidity action, this could decrease dissemination risks of hydatid liquid in the organism during operation. Also, this drug permits to reduce the operation time.

Background: Tubular injury triggered by hyperglycemia is an important pathological characteristic in diabetic nephropathy (DN). Accumulated advanced glycation end products and their precursor methylglyoxal (MGO), contribute to the development of DN. Carnosine has been shown to prevent the development of DN but the underlying mechanism still needs to be studied in depth.

Background: Gastric cancer (GC) remains one of the predominant malignant tumors within the digestive tract, yet its underlying biological mechanisms remain elusive. The primary objective of this study is to delineate the causal relationship between circulating metabolites and GC.
Method: The primary Mendelian randomization (MR) analysis was based on three large GWAS datasets.

We evaluated the quality, storage stability, and flavor-related compounds of breast meat from a novel Korean native chicken breed (Woorimatdag No. 2; WRMD2) and commercial broiler (CB) during seven days of aerobic cold storage. We found that pH and drip loss increased gradually during storage and WRMD2 exhibited a significantly lower pH and higher drip loss than CB.

Drugs such as angiotensin-converting enzyme inhibitors and angiotensin receptor blockers can improve muscle function and exercise capacity, as well as preventing, attenuating or reversing age-related losses in muscle mass, however, the exact mechanisms by which these drugs affect muscle cells, are not yet fully elucidated. Moreover, the potential epigenetic alterations induced in skeletal muscle tissue are also largely unexplored. The aim of this study was to evaluate if enalapril or losartan can change the physical performance and epigenetic profile of skeletal muscle in spontaneously hypertensive rats (SHRs).

Article Synopsis
- Co-amorphous systems (CAMs) can improve the solubility of poorly water-soluble drugs, but challenges like a limited number of co-formers and lab-scale preparation techniques exist.
- This study uses aspartame and dipyridamole to create CAMs through spray drying, showing that AspPhe has better solid-state properties and physical stability than individual amino acids.
- Molecular interactions analyzed by Hirshfeld Surface analysis and FT-IR spectroscopy demonstrate that hydrogen bond interactions significantly enhance the stability of the DPM-AspPhe co-amorphous system, while crystallization rates are affected by temperature and humidity.
