At the present time cancer is one of the biggest health problems and because of the problems encountered in its treatment, alternative treatment methods of herbal origin are researched. In this study, the cytotoxic effects of the essential oil extracted from the Micromeria congesta plant on various cancer cells (A549, ECC-1, HCT-116, HELA, HGC-27, MDA-MB-231, SNU-423, U20S, DLD-1, PC-3) and normal cells (BEAS-2B, CRL-4010) have been examined. Anticancer mechanism of action has been particularly examined on gastric cancer (HGC-27; IC50 15.84 µg mL-1), on which essential oil showed a high cytotoxic effect. In the study, the cytotoxic effect and the apoptotic effect have been applied by MTT and flow cytometric annexin-V methods, respectively. The apoptotic gene expression (caspase 3, caspase 9, MMP2, MMP9, ACTB) real-time PCR content analysis has been performed with gas chromatography mass spectrometry (GC-MS). M. congesta essentials oil has the highest cytotoxic effect on gastric cancer (HGC-27) cells, decreases MMP2 and MMP9 expressions, and induces apoptosis with increasing the expression of caspase 3 and caspase 8 genes. In addition, it has been determined that piperitenone oxide (40.00 - 45.00%), pulegone (11.00%) and cyclohexanone (18.00 - 19.00%) are the major components of M. congesta essentials oil. In conclusion, it has been determined that the compounds found in high amounts in M. congesta plant induces apoptosis by affecting the expression of compound genes and thus can have the potential to be an alternative drug in the treatment of gastric cancer.Colic is a clinical syndrome and has been defined as a visceral abdominal pain and/or acute abdominal disease. It is a common cause of morbidity and mortality in horses. The most common forms of colics are related to gastrointestinal tract in nature and most often linked to colonic disturbances. However, colics are not well understood in donkeys compared to those of in horses and the literature is poor regarding bowel strangulating obstruction in donkeys. This report described the clinical signs and post-mortem necropsy findings of an abdominal colic due to the left colon volvulus following a non-surgical castration using Burdizzo emasculatome in a 6-year-old donkey. The castration was done under local analgesia following a sedation with a combination of xylazine-acepromazine and physical restraint on a tilt table. Severe abdominal colic and death occurred after discharging from the hospital. Left colon volvulus at the sternal and diaphragmatic flexures in a ventromedial-dorsolateral direction of 720° was the main cause of colic found at the necropsy examination. Although left colon volvulus is not considered as a complication of castration, it maybe rational to prescribe an analgesic agent in postoperative care in donkeys undergoing non-surgical castration.Shewanella xiamenensis, a newly virulent zoonotic pathogen belonging to the genus Shewanella is the causative organism of emerging intra-abdominal infection, acute skin ulceration, rotten limbs and ascites in humans and animals. The global spread of S. xiamenensis entails severe economic impact. However, it was rarely reported as a cause of infection and no reports were found that S. xiamenensis isolated from clinical samples. The isolate was identified as a S . xiamenensis strain by 16S rDNA amplification and DNA sequencing identification method. Even if co-infection by other bacteria could not be ruled out, this is the first report of acute disease caused by S . xiamenensis in the Chinese giant salamander in China. By using the Kirby-Bauer disc diffusion method, the sensitivity of the isolate to clinical antibiotics was evaluated. Antibiotic susceptibility test indicated that the isolate was resistant to 32 antibacterial drugs such as kanamycin, florfenicol and ceftriaxone suggesting that the isolate was a multi-drug resistant strain.L isteria monocytogenes is a pathogen of great concern to the food industry. The present study was aimed to explore the clonal relationships amongst L. monocytogenes strains isolated from foods of animal origin (milk, beef, chevon (goat meat), pork and chicken) and fish. Forty-seven L. monocytogenes strains were characterized by pulsed-field gel electrophoresis (PFGE). The PFGE analysis using ApaI and AscI enzymes revealed 37 pulsotypes, with Simpson's discriminatory index of 0.987. This study demonstrated the presence of a few similar L. monocytogenes pulsotypes in different foods of animal origin in different places and years of isolation and this indicates that some L. monocytogenes subtypes may be ubiquitous which are acclimatizing and persisting in different foods of animal origin. This also emphasizes the importance of cross-contamination in local wet markets. Thus, the understanding of genetic diversity will contribute to the development of rational and workable strategies to control this important zoonotic infection.Meat and meat products are highly important sources of protein in the diet. Nowadays, the consumption of meat and meat products has increased owing to modern manufacturing techniques. Due to the economic value of meat, the use of unauthorized tissue is possible in meat products. In some cases, there is fraud in the percentage of meat in meat products to reduce prices. In this study, 34 samples of minced meat, hamburger and sausage were randomly collected from the markets in the northeast of Iran. Then, sections were stained using Hematoxylin and Eosin (H & E), Verhoeff-van-Gieson, Masson's trichrome and periodic acid-Schiff-Alcian blue stains. In this regard, for the first time, the efficacy of stereological technique to determine the percentage of meat listed in sausages and the possible existence of fraud was evaluated. The results showed that, due to the presence of some unusual tissues, histological technique could determine different tissues in meat products. The stereological results of control samples showed a very slight difference; whereas, the results for the samples collected from the city stores showed a distinctive difference regarding the percentage of meat compared to the percentage of label. Skeletal and smooth muscles, blood vessels, nerve, gizzard, adipose tissue, glandular tissue, cartilage, bone, tendon, skin, lymphatic tissues and plant materials were observed. It was confirmed that stereology was a reliable method to determine and confirm the percentage of meat used in meat products.Echocardiography illustrates a convenient and noninvasive tool for measuring cardiac output (CO) changes after administration of sedative drugs, but it is unknown in camelids practice. The aim of present study was to investigate echocardiographic effects of intravenous (IV) injection of medetomidine and xylazine in camel calves. Twenty apparently healthy immature male one-humped camel calves (Camelus dromedarious) were divided into four groups (five animals in each treatment). Medetomidine and xylazine were injected into the left jugular vein at two different doses of 10.00 and 20.00 μg kg-1 and 0.20 and 0.40 mg kg-1, respectively. Effects on some selected echocardiographic parameters were recorded at different intervals, before drug administrations (baseline) and after 3, 60 and 120 min. Data were analyzed by repeated measure, ANOVA test, then relevance and significance were taken as p ≤ 0.05. Significant decrease in fractional shortening percentage (FS%), ejection fraction percentage (EF%), stroke volume (SV), heart rate (HR) and subsequent CO were noticeable 3 min after drug administration in medetomidine high dose (MH), medetomidine low dose (ML) and xylazine high dose (XH) groups (p ≤ 0.05), furthermore at this time significant decrease in left ventricular mass (LVmass) and left ventricular systolic time intervals were seen in these groups, however, in xylazine low dose (XL) group, the lowest level of most echocardiographic parameters were detectable after 60 min. High dose IV injection of medetomidine was associated with significant decrease in most echocardiographic parameters without echocardiographic arrhythmia. Although, ML and XH groups had the same effects on echocardiographic indices but the intensity and duration were less than MH group.The effects of MitoTEMPO, a mitochondria-targeted antioxidant, and its non-targeted parent, TEMPO, on bovine oocyte maturation competence have not been determined so far. Hence, our study was aimed to investigate the effects of supplementing maturation medium with different concentrations of MitoTEMPO (0.00, 0.10, 1.00 and 10.00 µM) or TEMPO (0.00, 5.00, 10.00 and 15.00 mM) on in vitro maturation (IVM) and fertilization (IVF) of bovine oocytes. The oocytes after IVM and IVF were evaluated for the signs of nuclear maturation and normal fertilization. The average number of spermatozoa penetrated per oocyte and the level of intracellular reactive oxygen species (ROS) were also evaluated. The results showed that percentages of bovine oocytes reached the metaphase II stage of meiosis were significantly higher in the 1.00 µM MitoTEMPO group compared to the control group (without antioxidant supplementation). The normal fertilization rate also tended to be greater in this group than the control group. In comparison with the control group, the medium supplementation with 1.00 µM MitoTEMPO led to a significant decrease in the intracellular ROS level. The average number of spermatozoa penetrated per oocyte was not significantly different among the antioxidant-treated and the non-treated groups. The TEMPO addition to the maturation medium affected neither the rate of maturation/fertilization nor the level of intracellular ROS in bovine oocytes. Based on these results, we concluded that MitoTEMPO at a concentration of 1.00 µM had beneficial effects on the quality and fertilization potential of bovine oocytes.Inflammation is an initial response of the body to infection and relationship between inflammation and cancer has been established. Nuclear factor kappa B (NF-κB) is a central factor in inflammation and its activity contributes to tumor progression and apoptosis prevention consequently leading to cancer promotion. As a result, NF-κB inhibitors can cause apoptosis. In this study, the effect of mesalazine as a NF-κB inhibitor on growth and apoptosis of K562 cells has been investigated. The K562 cells were first cultured in RPMI-1640 medium containing 10.00% fetal bovine serum. After that, they were treated for 72 hr with different concentrations of mesalazine (20.00, 40.00, 60.00 and 80.00 μM mL-1). The MTT assay was used to evaluate cell viability. Hoechst staining and RT-PCR of apoptosis related genes (Bcl-2 and Bax) were carried out to illustrate apoptosis induction and immunocytochemistry was performed to investigate changes in c-Myc protein level. According to the results of MTT assay, all of applied mesalazine concentrations decreased K562 cells viability. https://www.selleckchem.com/products/asciminib-abl001.html Hoechst staining showed that the fragmented nuclei increased indicating apoptosis induction. Immuno-cytochemical results showed that mesalazine decreased c-Myc in treated cells. The RT-PCR results also showed an increase in Bax and a decrease in Bcl-2 expressions in mesalazine-treated cells. As the results suggest, mesalazine reduces cell viability by inducing apoptosis in K562 cell line; therefore, it can be used as a candidate for the leukemia treatment.
