Left displacement of the abomasum in dairy cows is a disease diagnosed all over the world. In Germany, a common method for its correction is laparoscopic abomasopexy (LA). The aim of the study was to assess cortisol and substance P concentrations, behavioral patterns, and feeding and rumination times during and after LA in cattle treated with xylazine before LA compared with nonsedated cattle. A total of 28 cattle that had been referred to a veterinary teaching hospital with a diagnosis of left displacement of the abomasum were randomly assigned to 1 of 2 groups. Surgery was performed according to a standardized protocol. Animals of XYL (n = 14) received xylazine (0.02 mg/kg body weight i.v.) before surgery, and animals of CON (n = 14) received a placebo (0.9% saline i.v.). All cows received ketoprofen (3 mg/kg body weight i.v.) twice, and benzyl penicillin procaine (20,000 IU/kg body weight i.m.) for 5 ± 1 d. Blood samples for the determination of plasma cortisol concentration (PCC) and plasma substance P coand rumination times did not differ between groups. Animals in XYL showed significantly more chews per bolus after surgery than animals in CON. In conclusion, administration of xylazine before LA results in lower stress levels for cattle during the course of LA, especially before being put into lateral and dorsal recumbency. Therefore, in the opinion of the authors, xylazine administration can be recommended before LA to improve the well-being of the animals during and after surgery.Excessive extracellular matrix deposition, in particular collagen, is an important cause of lung fibrosis. Heat shock protein 47 (HSP47), a collagen-binding protein, plays an important role in the intracellular processing of procollagen. A small molecule that blocks the collagen chaperone function of HSP47 has been reported as an HSP47 inhibitor. The aim of this study was to assess the effect of the HSP47 inhibitor on collagen synthesis and other fibrotic process in vitro. We evaluated collagen expression by western blot, and determined cell viability and migration by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and scratch test, respectively, in human and mouse lung fibroblasts. Treatment of lung fibroblasts with HSP47 siRNA decreased collagen type I expression. Similarly, the HSP47 inhibitor decreased collagen type I expression in transforming growth factor beta 1 (TGF-β1)-treated lung fibroblasts in a dose-dependent manner. The inhibitor also decreased the viability and cell migration ability of TGF-β1-treated lung fibroblasts. Overall, we demonstrated that HSP47 is a potential therapeutic target for pulmonary fibrosis. The small molecule HSP47 inhibitor may mediate antifibrotic effects by suppressing the overexpression of collagen, and inhibiting the viability and migration of fibroblasts. Further research is needed to clarify the therapeutic potential of this HSP47 inhibitor for pulmonary fibrosis.Anesthetic sevoflurane could induce neurotoxicity in developing brain and cause adverse neurobehavioral outcomes in mice, including inattention, social interaction deficit, and learning and memory impairment. However, there is less data on the effect of anesthesia plus surgery on social interaction behavior. Therefore, we investigated whether the combination of anesthesia and surgical stimulation could induce behavioral and biochemical changes in mice. Firstly, the six-day-old mice were received either 3% sevoflurane anesthesia or abdominal surgery under sevoflurane anesthesia. Then, these mice were scheduled to social interaction test in three-chambered social paradigm at one-month-old. In addition, the brain tissues of neonatal mice were harvested at 24 h after treatment, for measuring the levels of OXTR and NMDAR1 in Western blot analysis. We found that neonatal anesthesia with sevoflurane in a clinically-relevant dosage could not induce social interaction deficit. Nevertheless, anesthesia plus surgery was able to impair preference for social novelty in mice. Moreover, anesthesia plus surgery decreased the levels of OXTR in hippocampus and cortex of mice, as well as NMDAR1 in hippocampus. Collectively, these results suggested that anesthesia plus surgery could impair social novelty preference, but not sociability in mice, and that social memory might be more vulnerable than social affiliation in biological property. Furthermore, reduction in the levels of cortex OXTR and hippocampus NMDAR1 could be associated with social recognition memory in mice.The current antiretroviral therapy cannot cure the patients infected with human immunodeficiency virus type 1 (HIV-1) due to the existence of latently infected cells capable of virus production from harboring proviral DNA. MazF is an ACA nucleotide sequence-specific endoribonuclease derived from Escherichia coli. The conditional expression of MazF by binding of HIV-1 Tat to the promoter region of a MazF-expression vector has previously been shown to selectively inhibit HIV-1 replication in acutely infected cells. The expression of MazF significantly suppressed tumor necrosis factor (TNF)-α-induced HIV-1 production and viral RNA expression in the HIV-1 latently infected cell line OM-10.1 transduced with the MazF-expression vector (OM-10.1/MFR). Moreover, the viability of OM-10.1/MFR cells decreased with increasing concentrations of TNF-α, whereas such decrease was not observed for HL-60 cells transduced with the MazF-expression vector (HL-60/MFR), the uninfected parental cell line of OM-10.1. TNF-α increased the expression of cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase in OM-10.1/MFR cells, indicating that the cell death was caused by the induction of apoptosis. TNF-α-induced expression of MazF mRNA was detected in OM-10.1/MFR but not HL-60/MFR cells, suggesting that TNF-α-induced apoptosis of latently infected cells was due to the expression of MazF. selleck inhibitor Thus, the anti-HIV-1 gene therapy using the MazF-expression vector may have potential for the cure of HIV-1 infection in combination with suitable latency reversing agents through reducing the size of latently infected cells without viral reactivation.
