Background:Mastitis caused by different pathogens including Streptococcus uberis(S.uberis)is responsible for huge economic losses to the dairy industry.In order to investigate the potential genetic and epigenetic regulatory mecha‑nisms of subclinical mastitis due to S.uberis,the DNA methylome(whole genome DNA methylation sequencing)and transcriptome(RNA sequencing)of milk somatic cells from cows with naturally occurring S.uberis subclinical mastitis and healthy control cows(n=3/group)were studied.Results:Globally,the DNA methylation levels of CpG sites were low in the promoters and first exons but high in inner exons and introns.The DNA methylation levels at the promoter,first exon and first intron regions were nega‑tively correlated with the expression level of genes at a whole‑genome‑wide scale.In general,DNA methylation level was lower in S.uberis‑positive group(SUG)than in the control group(CTG).A total of 174,342 differentially methylated cytosines(DMCs)(FDR<0.05)were identified between SUG and CTG,including 132,237,7412 and 34,693 DMCs in the context of CpG,CHG and CHH(H=A or T or C),respectively.Besides,101,612 methylation haplotype blocks(MHBs)were identified,including 451 MHBs that were significantly different(dMHB)between the two groups.A total of 2130 differentially expressed(DE)genes(1378 with up‑regulated and 752 with down‑regulated expression)were found in SUG.Integration of methylome and transcriptome data with MethGET program revealed 1623 genes with signifi‑cant changes in their methylation levels and/or gene expression changes(MetGDE genes,MethGET P‑value<0.001).Functional enrichment of genes harboring≥15 DMCs,DE genes and MetGDE genes suggest significant involvement of DNA methylation changes in the regulation of the host immune response to S.uberis infection,especially cytokine activities.Furthermore,discriminant correlation analysis with DIABLO method identified 26 candidate biomarkers,including 6 DE genes,15 CpG‑DMCs and 5 dMHBs that discriminated between SUG and CTG.Conclusion:The integration of methylome and transcriptome of milk somatic cells suggests the possible involve‑ment of DNA methylation changes in the regulation of the host immune response to subclinical mastitis due to S.uberis.The presented genetic and epigenetic biomarkers could contribute to the design of management strategies of subclinical mastitis and breeding for mastitis resistance. 展开更多

Honeybees (Apis mellifera) are important pollinators of flowering plants and agricultural crops contributing annually to billions of dollars in revenues to crop production. Honeybees have an average lifespan between 8 weeks to 5 years. Dead honeybees are abundantly available in beehives and can be utilized as an alternative source to synthesize nanoparticles. In recent years, biologically synthesized nanoparticles have been preferred over their chemical counterparts. However, honeybee-based-green synthesis of nanoparticles has not been explored yet. Herein, we report the biosynthesis of silver nanoparticles from honeybees and its antibacterial activity. The synthesis of silver nanoparticles was monitored visually through a gradual change in color. Furthermore, the biosynthesized nanoparticles were confirmed and characterized by UV-visible spectroscopy. Scanning Electron Microscope was utilized to analyze the average size and morphologies of the biosynthesized nanoparticles. Subsequently, the antibacterial potential of the biosynthesized silver nanoparticles was tested against selected Gram-positive and Gram-negative bacterial strains. It was found that a distinct color change from yellow to brown in the reaction solution suggested the formation of silver nanoparticles. The biosynthesized nanoparticles exhibited absorption maxima at 430 nm. The SEM analysis confirmed the spherical and cuboidal shape of the biosynthesized silver nanoparticles with a size range between 10 - 40 nm. Furthermore, the biosynthesized silver nanoparticles exhibited strong antimicrobial potential against tested Gram-positive and Gram-negative bacteria strains by aggregating on the cell surface. This study showcases the biomedical and agricultural applications of biosynthesized silver nanoparticles from honeybee wings. . 展开更多

Objective: This study compares hemoglobin and erythropoietin levels in patients with polycythemia vera and secondary polycythemia. Study Design: A retrospective cross-sectional study evaluating the serum erythropoietin and hemoglobin levels in patients with polycythemia vera and secondary polycythemia. This study was performed simultaneously in Texas state of the U.S. and Fars Province in Iran. Methods: Hemoglobin, hematocrit and erythropoietin test results were collected from patients aged 19 to 75 years who were diagnosed with polycythemia vera and secondary polycythemia. Patients records with history of thrombocythemia, congestive heart failure, dyspnea, anemia and pregnant woman were excluded from study. Patients in each decade of life were examined in separate groups, so that changes in hemoglobin related to aging did not affect the research results. Results: 75% of the patients were men, and 25% were women. A total of 1580 patients were analyzed in this study. 57.3% of patients in UTMB and 38.8 patients in Iran have hemoglobin level above 17 mg/dl. 74% of patients in UTMB and 88% of patients in Iran have erythropoietin below 10 IU/mL. Polycythemia in UTMB was more common in people over 50 and in Iran in patients under 50 years old. The serum hemoglobin and erythropoietin levels in patients with polycythemia vera were not significantly different in compare to secondary polycythemia patients. Data showed that there were 84 polycythemia patients per 100,000 people. The results of this study in UTMB and Iran showed that 4.5% and 7%, respectively, of patients with polycythemia had a positive JAK2 test. Conclusion: Low erythropoietin levels may not be helpful in differentiating polycythemia vera from secondary polycythemia. . 展开更多

Introduction: Cutaneous endometriosis is an uncommon but well-known skin disorder that represents about 0.5% to 1% of all endometriosis. The objective of this case series is to report clinical presentation, diagnosis, and management of various forms of cutaneous endometriosis. Material and Methods: It was an observational, retrospective and descriptive review of cases presenting with cutaneous endometriosis among Cameroonian women managed at the gynaecological outpatient department of Yaounde Gynaeco-Obstetric and Pediatric Hospital. All the following parameters were analysed: age, parity, previous pelvic surgery, presenting symptoms and duration, associated symptoms, localizations, imaging, size of the lesion, other localization of endometriosis, management and histopathological results. Results: we reported 4 cases of cutaneous endometriosis, with 3 umbilical endometriosis and 1 abdominal scar endometriosis. Patient age ranged from 28 to 39 years with an average of 33 years. All patients described infertility (two primary and two secondary) and two had a history of abdominal surgery. All patients presented local cyclical signs such as pain, swelling, color change and bleeding. The duration of symptoms varied from 2 to 3 years and the size of lesions ranged from 2 to 3.5 cm for umbilical lesions and was 9 cm for abdominal scar endometriosis. In all cases, no imaging was required for the diagnosis, which was suspected on the basis of patient’s history and the cyclical nature of local signs, followed by wide surgical excision and confirmation on histopathology. Conclusion: Cutaneaous endometriosis is a rare benign condition. Umbilical endometriosis seems to be the main cutaneous localization and can be described as primary or secondary. Even if its diagnosis must be confirmed by histopathology, it should be considered in patient with cutaneous cyclic signs such as pain, swelling or bleeding with or without history of abdominal surgery. 展开更多

Healing properties have been observed in some species of Daphne plant. The effect of Daphne plant extract on the K562 cell line has been previously studied, and Gleevec is a well-known and effective medicine for the treatment of chronic myelogenous leukemia. Material and Methods: In this study, the simultaneous effects of using herbal medicine and a target therapy medicine on the K562 cell line were investigated. The presence of some species of Daphne in Iran motivated us to evaluate the cytotoxic effect of Daphne mucronata on human leukemia cancer cells. The antiproliferative activity of the dichloromethane extract of Daphne mucronate (Thymelaeaceae), a new anticancer medicinal plant, was evaluated. Cell viability was quantitated by MTT assay. Apoptotic and necrotic changes in the cell membrane were examined using flow cytometry. Changes in Bax and Bcl2 gene expression were investigated using real-time PCR. The MIC and the IC50 of the crude extract were calculated, and the MIC and IC50 of the Daphne extract in combination of imatinib were tested in the K-562 cell line. Results: K-562 cells responded to the extract treatments in a dose-dependent manner, and the increase in the expression of Bcl2 and decrease in the expression of the Bax gene intensified with increasing extract concentration. Flow cytometry revealed that most of the cells underwent necrosis. Conclusion: Daphne extract effectively decreased the viability of the K562 cell line. The necrotic effect of the Daphne extract was evaluated, and an increase in the gene expression of Bcl2 was observed in cells exposed to the Daphne extract. The combination of Daphne extracts with imatinib enhances the cytotoxic effect of imatinib. 展开更多

AIM:To identify factors predicting the clinical response of ulcerative colitis patients to granulocyte-monocyte apheresis (GMA). METHODS:Sixty-nine ulcerative colitis patients (39 F,30 M) dependent upon/refractory to steroids were treated with GMA. Steroid dependency,clinical activity index (CAI),C reactive protein (CRP) level,erythrocyte sedimentation rate (ESR),values at baseline,use of immunosuppressant,duration of disease,and age and extent of disease were considered for statistical analysis as predictive factors of clinical response. Univariate and multivariate logistic regression models were used. RESULTS:In the univariate analysis,CAI (P = 0.039) and ESR (P = 0.017) levels at baseline were singled out as predictive of clinical remission. In the multivariate analysis steroid dependency [Odds ratio (OR) = 0.390,95% Confidence interval (CI):0.176-0.865,Wald 5.361,P = 0.0160] and low CAI levels at baseline (4 < CAI <7) (OR = 0.770,95% CI:0.425-1.394,Wald 3.747,P = 0.028) proved to be effective as factors predicting clinical response. CONCLUSION:GMA may be a valid therapeutic option for steroid-dependent ulcerative colitis patients with mild-moderate disease and its clinical efficacy seems to persist for 12 mo. 展开更多

A 3-year-old Persian queen was referred to Teaching Veterinary Hospital while 3 neonates' umbilical cords were entangled with the queen's tail hair.Close inspection of the cat showed that the umbilical cords of 3 kittens had twisted around together and entangled with the moms' hairs in the base of tail region.Also this complex has been warped around the left tarsus of one of the involved kittens and caused swelling and skin darkness in the involved limb.Operation was carried out urgently.After cutting the queen's involved hairs the kittens were released.Then the twisted umbilical cords and the hairs were isolated from the umbilical cord and the involved leg was released from the umbilical cords and the twisted umbilical cords were separated from each other.During one week follow up,dry gangrene occurred in the distal extremity of the injured limb and consequently,amputation was performed on the distal part of tibia.Our clinical findings suggest that long hair coats of queens could be a maternal life threatening factor for neonates' life. 展开更多

Objective: To confirm the efficacy of non-antibiotic treatment with prostaglandin F2α(PGF2α) in dairy cows affected by severe clinical endometritis in (30±3) days in milk. Methods: Cows with clinical endometritis Ⅲ (n=399) were aligned into three groups randomly. The first group (n=115) received PGF2α, the second group (n=84) received intrauterine infusion (IUI) of oxytetracycline 10% + PGF2α, and the third group (n=200) received IUI. Cows were inseminated following estrus. The pregnancy status, parity, calving and artificial insemination season, ovaries with corpus luteum at the time of treatment, dystocia, body condition score and treatment groups were included in data analysis. Results: Total pregnancy rate was 40.1% after the first insemination and 94.2% after the third insemination. Overall pregnancy rate of treated cows with IUI+PGF2α(84.5%) was significantly lower than the treated cows with PGF2α(98.3%) or IUI (96%) (P<0.05). The first service pregnancy rate of inseminated cows in summer (14.3%) was lower in comparison with cows inseminated in spring (40.4%), fall (41.4%) and winter (51.7%) (P<0.05). Conclusions: PGF2α could treat severe clinical endometritis in dairy cows with corpus luteum in comparison with other treatments. 展开更多

In addition to that, it is a disturbing and restricting cerebrovascular disease with a substantial amount of remaining shortage leading on to emotional and financial burden on the family and society. A hospital-based retrospective study was conducted at Teaching Hospital Batticaloa, Sri Lanka from July 1, 2016, to October 31, 2016. During the study period, data were collected from the medical records. Out of 34 patients, 21 (61.8%) were males and 13 (38.2%) were females. The male to female ratio was 1.6:1. Out of 34 patients, 17 (50%) were affected in the left side and 17 (50%) were affected on the right side. The most common risk factor was hypertension with 79.4%, and next to that diabetes mellitus (41.2%), smoking (23.5%), alcohol (20.6%), past history of Stroke (17.6%) and ischaemic heart disease (IHD) (14.7%). Stroke due to infarction is more common than haemorrhage. In this study, both right and left sides were affected equally. In order to prevent this devastating stroke, acknowledgment of risk factors for stroke is prime importance for the healthcare workers as well as public. 展开更多

Background: Urinary tract infection caused by Escherichia coli is a frequently observed condition both in humans and animals. Uropathogenic E. coli (UPEC) has been shown to have a pathogenicity island that enables them to infect the urinary tract. Because there is little information about the presence of UPEC-associated virulent genes in animal isolates this work was carried out with the intent to enhance the understanding about the strains of E.coli that cause infections in animals. Results: We screened 21 E. coli strains isolated causing urinary tract infection in domestic animals. Primers were designed to amplify urinary infection-associated genes. Nine genes, papA, tcpC, fyuA, tpbA, Lma, hylA, picU, tonB, and flicC were then amplified and sequenced. Different from the human isolate CFT073, all the animals E. coli lack some of the pathogenesis-associated genes. Genes encoding for proteins used to scavenge iron appear not to be so necessary during animal infections as they are in human infection. In further investigation of phenotypic properties, it was observed that animal UPECs have significantly more impaired ability to form biofilms than human UPEC strain. Conclusions: This study identified significant differences between human and animal UPECs. This may have its roots in the fact that it is difficult to determine if an animal has symptoms. Future studies will focus on some of the observations. 展开更多

Its incidence is rising mostly due to induction of ovulation or Assisted Reproductive Technique. Most ectopic in heterotopic pregnancies are localized in the fallopian tubes. The occurrence of molar tubal ectopic pregnancy coexisting with intrauterine pregnancy is uncommon and consequently not often considered a diagnostic possibility. Case Report: We report the case of a 25-year-old woman, gravida 4 para 1, who complained of vaginal spotting and lower abdominal pain after 6 weeks of amenorrhea following clomiphene citrate ovarian stimulation. Transvaginal Ultrasonography revealed an intrauterine pregnancy and an unruptured left tubal ectopic pregnancy. She underwent successful laparoscopic salpingectomy while the intra-uterine pregnancy was allowed to continue. The ectopic pregnancy tissue histology reported an ectopic partial molar pregnancy. She subsequently had a normal vaginal delivery at 39 weeks and 3 days and her follow-up was uneventful. Conclusion: Heterotopic pregnancy is a rare but life-threatening condition. It should be suspected in a pregnant woman with a risk factor of multiple gestations who presents vaginal bleeding and lower abdominal pain in the context of early pregnancy. Laparoscopic surgery is effective for confirming the diagnosis and treating the ectopic component. Routine histological examination of tubal specimens must be taken very seriously because some findings like molar pregnancies may require specific management. 展开更多

Our objectives were<span "=""> to determine the prevalence of SICH, describe the clinical profile, aetiology and evaluate the prognosis (fatality case, functional outcome) of patients in a tertiary health care hospital in Cameroon. <b>Methods:</b> This was a hospital-based retrospective cohort</span><span "=""> </span><span "="">which included patients with SICH and followed up for 6 months after stroke. Subarachnoid haemorrhage, cerebral venous thrombosis with bleeding or bleeding related with ischemic or brain tumour were excluded. Predictive factors were obtained using multiple logistic regression and survival by Kaplan Meier method. <b>Results:</b> The prevalence of SICH was 37% with male predominance (64.0%), a mean age of 55.6 ± 11.8 years. Deep coma was found in 30.3% on admission. The basal ganglion was the most frequent location of haemorrhage (85.1%) while intraventricular blood effusion, mass effect, cerebral oedema and herniation occurred in 31.4%, 25.7%, 8.8% and 5.0% respectively. Hypertension (57.5%) was the most common aetiology. The mean length of hospitalization was 9.0 ± 7.7 days and chest infection (30.7%) was the most frequent complication. The cumulative case fatality rate after 24 hours (day 1), during admission, month 1 and month 3 was 9.6%, 39.9%, 46.0%, 59.8% respectively. On multivariate analysis, GCS < 9 [OR (95% CI) = 3.538 (1.086 - 11.526), p = 0.036] and NIHSS 15 - 24 [OR (95% CI) = 7.498 (1.306 - 43.029), p = 0.024] were independent predictors of in-hospital mortality while mass effect [OR (95% CI) = 3.563 (1.217 - 10.432), p = 0.020] and hyperthermia [OR (95% CI) = 4.645 (1.341 - 16.085), p = 0.015] predict poor functional outcome. Six</span>-<span "="">month survival was 37.8%. <b>Conclusion:</b> About one</span>-<span "="">third of stroke patient were haemorrhagic. Hypertension is the leading CVRF and aetiology of spontaneous ICH.

Group discussion teaching technique for small groups and encouragement of critical but constructive and creative thinking for finding new and efficient solutions can lead to provision of better health and medical services that is defined in clinical setting, as the clinical psychology finds a way for curing and education. The present study was conducted with the aim to compare the effects of creative group teaching and educational booklet on interpersonal skills of midwives in a clinical setting. The present study was conducted on 97 midwifery graduates working in hospitals in Kerman Province, in two groups of educational booklet (49 midwives) and educational workshop (48 midwives) who participated in a 3-day creative teaching workshop in summer 2015. Creative problem-solving teaching intervention group was taught through educational workshop method, including small group and team working, group discussion and mini lectures. Midwifery 1 intervention group was provided with an educational booklet validated by professors of Nursing and Midwifery School for independent and individual study by midwives working in Kerman Province hospitals. The two groups were matched in terms of personal details. Hospitals were randomly selected, and midwives were selected by quota sampling. Interpersonal communication skills of both groups were assessed before and after intervention, and two months later using Interpersonal Communication Skills Test. The results obtained were analyzed in SPSS-16 using descriptive statistics, including frequency and percentage, mean and standard deviation, and inferential statistics including U-Mann-Whitney, paired t, independent t, repeated measures ANOVA tests at significance level of P P P P P < 0.001). Both teaching methods improved midwives’ interpersonal communication skills. Therefore, standardized educational booklets which produce cost-effective similar results are recommended. 展开更多
