Partial replacement of fish meal with Moringa oleifera leaf meal in practical diets of Cirrhinus mrigala fingerlings / Substituição parcial da refeição de peixe com farinha de folha de Moringa oleifera em dietas práticas de dedos Cirrhinus mrigala

Fish protein is serving as a source of nutrition for protein starving world. However, sustainable aquaculture products require inexpensive plant by-products due to finite sources of fish meal. Therefore, this study was conducted to examine nutrient utilization, growth performance and hematological indices of Cirrhinus mrigala fingerlings fed on Moringa oleifera leaf meal (MOLM) based diets. Fish were fed with six isonitrogenous and isoenergetic diets having MOLM as a substitute of fish meal (FM) at the levels of 0%, 10%, 20%, 30%, 40% and 50% for the period of 90 days. Fingerlings having initial weight 6.35±0.04g were reared in triplicate tanks at the stocking density of 15 and hand fed at the rate of 5% of total biomass twice regularly. Chromic oxide inclusion level was 1% in diets. After analysis, maximum growth performance and improved digestibility of nutrients were found in fish fed with diet at 10% replacement level as compared to fish fed on control diet and other test diets. Additionally, it was found that the red blood cells, white blood cells, hemoglobin and mean corpuscular hemoglobin concentration of fish showed a significantly (p<0.05) inverse correlation with the increase in MOLM. In present research, it was concluded that MOLM has good potential to be used as a FM substitute in C. mrigala diet with maximum effect at 10% showing positive hematological indices.

A proteína do peixe está servindo como fonte de nutrição para o mundo faminto por proteína. No entanto, produtos de aquicultura sustentáveis requerem subprodutos vegetais baratos devido às fontes finitas de farinha de peixe. Portanto, este estudo foi conduzido para examinar a utilização de nutrientes, o desempenho do crescimento e os índices hematológicos de alevinos de Cirrhinus mrigala alimentados com dietas à base de farelo de folhas de Moringa oleifera (MOLM). Os peixes foram alimentados com seis dietas isonitrogênicas e isoenergéticas contendo MOLM como substituto da farinha de peixe (FM) nos níveis de 0%, 10%, 20%, 30%, 40% e 50% pelo período de 90 dias. Os alevinos com peso inicial de 6,35 ± 0,04g foram criados em tanques triplicados com densidade de 15 animais e alimentados à mão a uma taxa de 5% da biomassa total duas vezes regularmente. O nível de inclusão de óxido crômico foi de 1% nas dietas. Após análise, desempenho máximo de crescimento e melhor digestibilidade de nutrientes foram encontrados em peixes alimentados com dieta em nível de reposição de 10% em comparação com peixes alimentados com dieta controle e outras dietas teste. Além disso, verificou-se que as concentrações de hemácias, leucócitos, hemoglobina e hemoglobina corpuscular média dos peixes apresentaram correlação inversa significativa (p < 0,05) com o aumento do MOLM. Na presente pesquisa, concluiu-se que o MOLM tem bom potencial para ser utilizado como substituto do FM na dieta de C. mrigala com efeito máximo a 10% apresentando índices hematológicos positivos.

Monitoring of Insecticides resistance against cotton Jassid (Amrasca biguttutla biguttutla) under laboratory conditions / Monitoramento da resistência de inseticidas contra o algodão Jassid (Amrasca biguttutla biguttutla) em condições laboratoriais

Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance level against field population of jassid through leaf dip method. Very low resistance level was found in jassid against confidor whereas high level of resistance was observed by pyriproxyfen against other test insecticides. Gradual resistance was observed against diafenthiuron. It is concluded that for the management of Jassid repetition of same insecticide should be avoided. The use of confidor may be reduced to overcome resistance against Jassid.

Desenvolvimento da resistência a inseticidas principalmente em dobradiça com técnicas de manejo para o controle de jassid, Amrasca biguttutla biguttutla. Cinco inseticidas foram aplicados contra populações de jassídeos coletados em campo e em laboratório durante os anos de 2017 a 2019 para traçar o perfil de seu nível de resistência contra populações de jassídeos em campo através do método de imersão nas folhas. Nível de resistência muito baixo foi encontrado em jassid contra confidor, enquanto alto nível de resistência foi observado por piriproxifeno contra outros inseticidas de teste. Resistência gradual foi observada contra o diafenthiuron. Conclui-se que, para o manejo do jassid, a repetição do mesmo inseticida deve ser evitada. O uso de confidor pode ser reduzido para superar a resistência contra jassid.

Comparison of clinicopathological characteristics of endogenous and exogenous cervical cancer with its clinical significance

Background:Cervical cancer is the third leading cause of cancer death in women of less developed countries due to poor screening and decreased diagnostic approaches. We aimed to investigate and differentiate the distinct clinicopathological characteristics and prevalence of endogenous and exogenous cervical in hospitalized patients. Methods:A study was performed contained 663 patients that were enrolled and underwent for screening of endogenous and exogenous cervical cancer in Qilu Hospital of Shandong University, from January 2010 to March 2015.Results:Our results indicated that combined examination of thin-prep liquid-based cytology test and human papillomavirus(HPV)-DNA are effective for diagnosis of endogenous and exogenous cervical cancer. The clinicopathological characteristics based on tumor growth pattern, and highrisk HPV-DNA incidence had no significant difference (p>0.05) in endogenous and exogenous cervicalcancer patients. The higher ratio of lymph node metastasis in endogenous cervical cancer and exogenous cervical cancer during IB1-stage (24.3% vs 12.9%), and in IIA2-stage (36.4% vs 25%) was observed respectively. In addition, our data provide compelling evidence that the level of deep interstitial infiltration, and lymphatic vascular infiltration in endogenous cervical cancer was collectively higher (82.7% and 33%) compared to exogenous cervical cancer (62.4% and18.3%) respectively during all stages.Conclusions:The higher percentage of lymph node metastasis,deep interstitial infiltration, and lymphatic vascular infiltration was observed in endogenous cervical cancer which might be the biomarker and differential key points for the diagnosis of endogenous cervical cancer. Taken together, our study provides clinicopathological features to diagnose, and differentiate the endogenous and exogenous type cervical cancer with its prevalence.

Assessment of the risk factors associated with multidrug-resistant tuberculosis in Sudan: a case-control study / 한국역학회지

OBJECTIVES: The emergence of multidrug-resistant tuberculosis (MDR-TB) is a major challenge for the global control of tuberculosis (TB). The aim of this study was to determine the risk factors associated with MDR-TB in Sudan. METHODS: This case-control study was conducted from May 2017 to February 2019. Patients newly diagnosed with MDR-TB were selected as cases, and controls were selected from TB patients who responded to first-line anti-TB drugs. A questionnaire was designed and used to collect data from study participants. Logistic regression was used to evaluate associations between risk factors and MDR-TB infection. The best multivariate model was selected based on the likelihood ratio test. RESULTS: A total of 430 cases and 860 controls were selected for this study. A history of previous TB treatment (adjusted odds ratio [aOR], 54.85; 95% confidence interval [CI], 30.48 to 98.69) was strongly associated with MDR-TB infection. We identified interruption of TB treatment (aOR, 7.62; 95% CI, 3.16 to 18.34), contact with MDR-TB patients (aOR, 5.40; 95% CI, 2.69 to 10.74), lower body weight (aOR, 0.89; 95% CI, 0.87 to 0.91), and water pipe smoking (aOR, 3.23; 95% CI, 1.73 to 6.04) as factors associated with MDR-TB infection. CONCLUSIONS: Previous TB treatment and interruption of TB treatment were found to be the main predictors of MDR-TB. Additionally, this study found that contact with MDR-TB patients and water pipe smoking were associated with MDR-TB infection in Sudan. More efforts are required to decrease the rate of treatment interruption, to strengthen patients’ adherence to treatment, and to reduce contact with MDR-TB patients.
