The advancements in the field of nanotechnology have provided a great platform for the development of effective antiviral vaccines. Liposome-mediated delivery of antigens has been shown to induce the antigen-specific stimulation of the humoral and cell-mediated immune responses. Here, we prepared dried, reconstituted vesicles (DRVs) from DPPC liposomes and used them as the vaccine carrier system for the Middle East respiratory syndrome coronavirus papain-like protease (DRVs-MERS-CoV PLpro). MERS-CoV PLpro emulsified in the Incomplete Freund’s Adjuvant (IFA-MERS-CoV PLpro) was used as a control. Immunization of mice with DRVs-MERS-CoV PLpro did not induce any notable toxicity, as revealed by the levels of the serum alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN) and lactate dehydrogenase (LDH) in the blood of immunized mice. Immunization with DRVs-MERS-CoV PLpro induced greater antigen-specific antibody titer and switching of IgG1 isotyping to IgG2a as compared to immunization with IFA-MERS-CoV PLpro. Moreover, splenocytes from mice immunized with DRVs-MERS-CoV PLpro exhibited greater proliferation in response to antigen stimulation. Moreover, splenocytes from DRVs-MERS-CoV PLpro-immunized mice secreted significantly higher IFN-γ as compared to splenocytes from IFA-MERS-CoV PLpro mice. In summary, DRVs-MERS-CoV PLpro may prove to be an effective prophylactic formulation to prevent MERS-CoV infection.

Hepatotoxicity, micronutrients insufficiency and cost of micronutrient supplements are challenges faced by HIV infected patients on antiretroviral therapy (ART). This study investigated the effect of natural plant micronutrients (vitamins A, C, and E, selenium and Zinc supplements from carrot-ginger (75:25) blend on liver enzymes: Alanine transaminase (ALT) and Aspartate transaminase (AST), CD4 +  T lymphocytes and body mass index (BMI) of HIV-infected-patients taking ART. Ninety HIV-infected-patients attending Special Treatment Clinic, Kafanchan General Hospital, Kaduna State, Nigeria, were randomized into three groups of thirty patients each: Group 1 is control group and received ART alone, Group 2 is standard group and received ART with ready to use commercial micronutrient supplement (SelACER supplement) while Group 3 is supplement group and received ART + Carrot-Ginger blend for 90 days. Serum Alanine, Aspartate transaminase, CD4 + T lymphocytes and BMI were assessed using standard methods at baseline (day 0), 30 days, 60 days and 90 days. The results indicated that patients on CarrotGinger blend and SelACER micronutrients supplements show significant (p<0.05) reduction in ALT and AST level. However, there was no significant (p>0.05) difference in patients treated with ART alone when compared to their baseline values. The results indicated that patients on carrot-ginger blend and SelACE® supplements had significant (p<0.05) increase in BMI, CD4+ T-cell counts, serum vitamins A, C, E, selenium and zinc from day zero. There was no significant (p>0.05) difference in patients treated with ART alone compared to their baseline values. In addition, patients on SelACE® supplement revealed significant (p<0.05) difference in their mean BMI, CD4+ T-cell counts, serum vitamins A, C, E, Selenium and Zinc compared to patients on carrot-ginger blend after 90 days. The results also indicated a strong positive association (r=0.97) between serum ALT and AST activity and between CD4+ T cell counts and body mass index (r=0.77) after 90 days. Therefore, micronutrients supplementation of HIV patients during ART treatment with Carrot-Ginger blend could also be a beneficial adjunct to ART due to its potentials to reconstitute the immune system and protect the liver in HIV individuals on ART.

Abstract The aim of the present study was to evaluate the effects of reducing dietary crude protein (CP) levels and supplementing rumen-protected methionine (RPM) on blood parameters and ruminal metabolites in lactating Holstein dairy cows. A total of 30 lactating Holstein dairy cows (60 ± 7 d in milk; mean ± SD) were randomly assigned to 1 of 2 treatments: diet containing 17.3% CP without RPM (control group; CON); diet containing 16.4% CP with supplementing 15.0 g/d of RPM (treatment group; RPM). All repeated, continuous data were subjected to PROC MIXED procedure of SAS (SAS version 9.2, SAS Institute Inc., Cary, NC.). The results related to blood showed that cows in RPM group exhibited lower concentration of blood urea nitrogen than that in CON group (P &lt; 0.001). Moreover, there were no differences among treatments on concentrations of aspartate transaminase, alanine transaminase, alkaline phosphatase, globulin and albumin (P &gt; 0.05). In ruminal metabolites, microbial CP (MCP) of dairy cows in RPM group was higher compared with CON group (P = 0.006). The concentrations of butyrate, valerate and isovalerate of RPM group were higher than that of CON group at 2h after feeding (P &lt; 0.05). In conclusion, lower dietary CP with RPM supplementation could improve nitrogen utilization of dairy cows and synthesis of MCP in rumen, as well as change volatile fatty acids production at 2h after feeding.

Abstract Purpose To evaluate the prognostic value of the aspartate transaminase/alanine transaminase (AST/ALT) ratio in primary non-muscle-invasive bladder cancer (NMIBC) using propensity score matching (PSM) analysis. Methods We retrospectively collected the clinical and pathological data from 314 patients with primary NMIBC who underwent transurethral resection of bladder tumor. The full cohorts were divided into a low AST/ALT ratio group and a high AST/ALT ratio group according to the optimal cut-off value which was obtained based on the analysis of the receiver operating characteristic curve for the 3-year recurrence-free survival (RFS). After 1:1 PSM, the correlation between preoperative AST/ALT ratio and survival prognosis was evaluated by Kaplan–Meier analysis with log-rank tests. The independent prognostic factors for RFS and progression-free survival (PFS) were also analyzed. Results The optimum cutoff value of the preoperative AST/ALT ratio was 1.40. Before PSM, a high AST/ALT ratio was correlated with the larger proportion of age > 60 years (P = 0.007) and the worse pathological T stage (P < 0.001). After PSM, patients with a high AST/ALT ratio had poorer RFS and PFS than patients with a low AST/ALT ratio (all P < 0.001). In addition, multivariate Cox regression analysis indicated that preoperative AST/ALT ratio was considered as an independent prognostic factor of RFS (HR 2.865; 95%CI 1.873–4.381; P < 0.001) and PFS (HR 4.771; 95%CI 2.607–8.734; P < 0.001) in patients with primary NMIBC. Conclusions The high AST/ALT ratio group tended to have poorer RFS and PFS than the low AST/ALT ratio group. Our results also indicated that the elevated preoperative AST/ALT ratio could be seen as a useful prognostic biomarker for predicting early disease recurrence and progression in patients with primary NMIBC.

Hepatocellular utility is observed by measuring the hepatocellular enzymes. Changes in its serum levels are related to liver dysfunction. Liver is one of the immunoprotective organs. Continuous use of immunosuppressive drugs can cause oral candidiasis and give effects to liver function. Hyperbaric oxygen treatment (HBOT), while reducing fungal infections, can also repair the liver function. The aim of this study was to investigate the alanine transaminase (ALT) and aspartate transaminase (AST) levels of immunosuppressed rats with oral candidiasis treated with hyperbaric oxygen. Twelve Wistar rats were divided into three groups: K− (normal/ healthy), K+ (oral candidiasis immunosuppressed rats), and P (oral candidiasis immunosuppressed rats treated hyperbaric oxygen). K+ and P groups were immunosuppressed by giving dexamethasone 0.5 mg/day/rat orally for 14 days, added with tetracycline 1 mg/day/rat. HBOT was given in five days successively. Blood serum of rats in all groups were taken to calculate the ALT and AST levels. ALT and AST levels in K+ showed higher value than K− and P groups. The data were analysed with one-way ANOVA test and showed significant difference in ALT levels (p < 0.05), while in AST levels there was no significant difference among the groups (p > 0.05). This study showed that HBOT affected the ALT and AST levels of immunosuppressed rats with oral candidiasis.

The aim of this study is to investigate the effect of platelet on the improvement of deteriorated liver function after liver resection. Six patients with hepatocellular carcinoma and liver cirrhosis have received the partial hepatectomy in the institution. Their Child–Pugh grade was B, and platelet count was below 7,000/µl. After hepatectomy, 20 units of platelet transfusion were carried out, liver function and side effects were investigated after 4 weeks, and the number of platelets increased to approximately 15,000/µl. Liver functions, such as aspartate transaminase (AST), alanine aminotransferase (ALT), cholinesterase (ChE), and prothrombin time, as well as albumin, recover to the same level as those before operation and 4 weeks after the operation. Any side effects were not recognized in all patients. Administration of platelets for cirrhotic patient with hepatectomy was carried with safety. But remarkable effect on the improvement of liver function was not recognized.

Background: In recent years, the observed frequency of hospitalization of patients taking mephedrone with other psychoactive substances has increased. There are no data in the literature on the effect of mephedrone use on liver function in patients, including the frequency of HCV infection. We have analysed the impact of taking mephedrone together with other psychoactive substances on the incidence of HCV infection. We have also analysed the effect of taking mephedrone with heroin, alcohol, and benzodiazepines on liver enzyme levels. Methods: The study included patients taking mephedrone with: alcohol (n = 115), heroin (n = 85) and benzodiazepines (n = 130) hospitalized in 2010–2018. The control group consisted of patients addicted to alcohol (n = 180), heroin (n = 221) and benzodiazepines (n = 152). Clinical data and laboratory findings were collected from medical records. Results: Taking mephedrone together with benzodiazepines is a statistically significant predictor of HCV infection in this group of patients, OR (8.44); 95% CI 5.63–12.64; p <0.001). A statistically significant interaction of the group with HCV infection was observed, i.e., for the level of alanine transaminase (p < 0.001) and aspartate transaminase (p < 0.001). Increased levels of liver enzymes in each of the studied groups was characteristic in patients with HCV infection (p <0.001). Taking additional mephedrone by this group of patients did not increase the level of liver enzymes. Conclusion: HCV infection is a statistically significant factor affecting the increase in liver enzymes levels in the group of patients taking mephedrone.
