A growth trial of 90 days was conducted on 15 Jersey crossbred female calves (Av. weight, 70.68 ± 2.90 kg; Av. age, 197.73 ± 12.40 days), equally divided into three groups of 5 animals each, i.e., control (T₀), treatment 1 (T₁), and treatment 2 (T₂). All animals were fed total mixed ration (TMR) prepared with a concentrate mixture, chaffed paddy straw, and green fodder at the ratio of 40:30:30 on DM basis. Calves under the control group were fed with TMR containing a standard mineral mixture having dicalcium phosphate (DCP) as a Ca source. Calves under T₁ group were supplemented with TMR containing fresh conch shell powder (FCSP), and T₂ calves were fed with TMR containing conch shell calcined powder (CSCP) as Ca source. We observed 11.66% increase (p < 0.01) in Ca concentration in CSCP compared to FCSP. The concentration of minerals like Mg, Co, Mn, and Fe was enhanced in CSCP compared to the FCSP. However, the calcination process of fresh conch shell powder (FCSP) reduced the concentration of Cu, and Zn. The Ca/P ratio was estimated as 2.11, 2.06, and 2.10 in T₀, T₁, and T₂ diets, which could be considered ideal for calf ration. Calves under T₁, and T₂ groups consumed significantly (p < 0.001) greater amounts (g/kg W^0.75) of DM and CP compared to T₀. However, increased voluntary intake did not translate into increased body weight gain (kg), and feed conversion ratio (kg DMI/kg gain) in T₁ and T₂ groups in comparison to T₀. We observed similar blood glucose, urea, alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine transaminase (ALT) concentration among the three treatments. Ca, and P levels in blood plasma were also identical among the three groups. The digestibility of Ca was increased significantly (p = 0.01) in FCSP (T₁)- and CSCP (T₂)-treated calves compared to control (T₀) calves. Similarly, T₁ and T₂ enhanced P digestibility compared to T₀. This first report with short-term experimentation depicted some promising scope for the use of locally available conch shell powder (fresh or calcined form) as a potential source of Ca for feeding to livestock, because these new sources of Ca did not affect intake, digestibility of Ca and P, growth performance, blood chemistry, and liver enzymes negatively in weaned crossbred calves.</p>","PeriodicalId":8917,"journal":{"name":"Biological Trace Element Research","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140027318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weighted multivariable logistic regression models showed that high cotinine level (≥ 0.05 ng/mL) was associated with increased odds of MetS [odds ratio = 1.54, 95% confidence interval: 1.01, 2.36], and the association between Zn intake levels and MetS did not demonstrate statistical significance. Importantly, the multiplicative interaction term between low Zn intake (≤ 4.89 mg/1000 kcal) and high cotinine level was related to higher odds of MetS (p-value for interaction 0.018).

However, there was no significant relationship between cotinine levels and MetS risk in the group with high Zn intake. The effect modification by Zn intake on the relationship of tobacco smoke exposure and risk of MetS is significant in individuals who had a sedentary time of ≥ 6 h, identified as non-Hispanic White, or resided in households with smokers.

Therefore, this work presents the results of literature research combined with a case report on a 3-year-old female vicuña (Vicugna vicugna) presented to the clinic from a zoological garden in northern Germany. The animal showed reduced food intake, recumbency, bruxism, icteric mucous membranes and sclera. Auscultation revealed atony of the third compartment and the digestive tract. Similar to cases described in the literature, the animal showed rapid deterioration of its condition with unspecific symptoms of liver failure and rapid death. However, in contrast to descriptions in sheep, clinical icterus has not been previously reported in cases of other SACs. Laboratory findings from EDTA and serum samples revealed neutrophilia with a left shift, hypoproteinaemia, lymphopaenia, azotaemia, elevated levels of creatine kinase (CK), aspartate aminotransferase (AST) and glutamate dehydrogenase (GLDH) in the serum. Hyperbilirubinaemia and significantly elevated serum and liver Cu levels were observed.

The present study aims to evaluate the potential protective effect of gold nanoparticles and phthalocyanine-gold nanoconjugates (Pc-Au NCs) against the hepatorenal toxicity of silver nanoparticles in male rats. Herein, 60 adult male Rattus norvegicus rats were divided into six equal groups (n = 10/group); the first group was kept as control, the second received gold nanoparticles (Au NPs) intraperitoneally (10 µg/kg) daily for 3 weeks, the third group is gold-phthalocyanine (Pc-Au) group where rats were injected intraperitoneally with gold-phthalocyanine for 3 weeks (10 µg/kg), the fourth group received silver nanoparticles (Ag NPs) (4 mg/kg) daily intraperitoneally for 3 weeks, the fifth group is silver + gold nanoparticles group (Ag + Au), and the sixth is silver + gold-phthalocyanine nanoconjugates (Ag + Pc-Au) group in which rats were intraperitoneally injected firstly with Ag NPs (4 mg/kg) for 3 weeks then with gold or gold-phthalocyanine for another 3 weeks (10 µg/kg). Our results revealed that Ag NPs could increase the serum AST, ALT, ALP, urea, creatinine, and lipid profile and significantly decreased the total protein and albumin. Moreover, histopathological alterations detected in the kidney and the liver of the Ag NPs group included vascular congestion, inflammatory cell infiltration, and tissue distortion. Alongside, exposure to Ag NPs induces hepatic and renal oxidative stress by suppressing the antioxidant-related genes including glutathione peroxidase 1 (gpx1), superoxide dismutase (sod), and catalase (cat). Ag NPs also upregulated the hepatic and renal genes involved in inflammation such as the interleukin-6 (il-6) and tumor necrosis factor-α (tnf-α), nuclear factor kappa B (nf-κβ), apoptosis such as the BCL2 associated X (bax), casp3, and other related to metabolism including asparagine synthetase (asns), suppressor of cytokine signaling 3 (socs3), MYC proto-oncogene (myc), and C-C motif chemokine ligand 2 (ccl2). On the other hand, treatment with Au NPs and Pc-Au NCs could effectively ameliorate the hepatorenal damages induced by Ag NPs and improve liver and kidney architecture and function, especially in the Pc-Au NCs group.
