This paper was designed to analyze the effect of ochratoxin A (OTA) contaminated feed on the growth outcomes, certain serum biochemical, histopathology, and OTA residue in the dorsal muscle, liver, and kidney in Nile tilapia. Also, to improve the drastic effect of OTA through dietary supplementation of hydrated sodium aluminum silicates nanoparticles or nano copper. For performing the present study, 270 fish were randomly allotted into 6 equal groups according to ochratoxin and nanoparticles of hydrated sodium aluminum silicates or copper oxide. The results indicated that supplementation of two levels of both nanoparticles (aluminum silicate or copper) as a mycotoxin adsorbent could prevent ochratoxicosis in Nile tilapia fish. In addition, they maintained optimal growth performance, feed efficiency without bad effect on serum profiles and vital organs function of fish in a dose-dependent manner. Histopathologically, the most interesting finding was the precipitation of calcium salts known as nephrocalcinosis, within the tubules, upon the degenerative tubules and tunica intima and media of the blood vessels in the control positive group. These pathological lesions were mitigated by nanoparticle supplementation. Thus increase the safety of fish products.

Neonatal calf diarrhea is a frequent disease of calves and may result in dehydration and metabolic acidosis. The disease causes mortality and reduces growth and future productivity. Early identification of disease improves calf outcomes and thus there is increasing interest in technological methods for detecting disease.

Heart failure (HF) and renal dysfunction often coexist and interact in many complex and bidirectional pathways, leading to detrimental effects on patient outcomes. The treatment of HF patients with renal dysfunction presents a significant clinical challenge. Interestingly, sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNI), may have beneficial effects on cardiac and renal outcomes in patients with HF with reduced ejection fraction, particularly by slowing the rate of decrease in the estimated glomerular filtration rate compared to a single angiotensin-converting enzyme inhibitor.

With its advantages of high cross-sectional utilization, shallow depth, and uninterrupted surface road traffic, the pipe-jacking method has been widely used in underground passages, metro stations, and other projects. However, this leads to a large volume of pipe-jacking waste soils that must be processed. Pipe-jacking waste soils are different from shield-tunneling waste soils.

A nanocomposite consisting of gold nanoparticles (AuNPs), poly(diallyldimethylammonium chloride) (PDDA), and reduced graphene oxide (rGO) was fabricated by a two-step chemical reduction method. Firstly, a PDDA-rGO composite was prepared by using hydrazine hydrate as a reducing agent. Subsequently, the AuNP-PDDA-rGO composite was prepared in ethylene glycol with PDDA-rGO and HAuCl as raw materials using sodium citrate as a reduction agent.

Sacubitril/valsartan, a first-in-class angiotensin receptor neprilysin inhibitor, is widely used to treat heart failure. Despite its efficacy, sacubitril/valsartan inevitably causes adverse events such as hypotension, renal dysfunction, hyperkalemia, and angioedema. Sacubitril/valsartan-associated ototoxicity is often underreported in clinical studies and real-world settings.
