Evaluation Of Soil Conditioner (Barbary-Plant (BP) Fertilizer) On Cucumber Hybrids (Cucumis Sativus L.) Under Cooled Plastic Houses Conditions In Khartoum State

This experiment was conducted for two successive seasons (June to September 2016 and January to mid April 2017) in cooled plastic house at Shambat Research Station, Agricultural Research Corporation, Sudan. The objective of this study is to investigate the effect of Barbary - plant (BP) fertilizer; third generation (G3) on growth and yield of two cucumber hybrids. The experiment was laid out in a split plot design with four fertilizer treatments namely; 50g Barbary-Plant (BP) fertilizer, 75 g (BP), 100 g (BP) and (NPK) fertilizer as a check in rate 1.0 - 12.5g / plant during season, used as a sub plot, and two hybrids (A and B) as main plot replicated three times. The means were compared using Duncan Multiple Range Test (DMRT) at P < = 0.05. Seventy five g of (BP) per plant resulted in a significant increase in plant height, number of flowers and fruits per plant, total fruit yield (kg/m2), number of fruits/m2, fruit height and fruit diameter followed by 50 g (BP), NPK and 100g (BP). Moreover, using of 75 g (BP) resulted in a significant saving of water irrigation followed by 50 g (BP) and 100 g (BP). Likewise, using of (B-P) reflecting in controlling of pests and diseases and extended the harvesting period of the crop. Based on the statistical and economical analysis, the study recommended the application of the soil conditioner Barbary-plant (BP) at the rate of 75g per plant of cucumber (60kg (BP) / 300m2) in Sudan

Molecular detection of Mycobacterium tuberculosis and its relationship to histopathological diagnosis in paraffin-embedded lymph node tissues

Background: Tuberculous lymphadenitis (TBL) is one of the most common forms of extra pulmonary tuberculosis (EPTB) worldwide, with difficulty in its diagnosis. And since in the Sudan, the routinely used method for diagnosis is conventional histopathology, the aim of this study was to confirm the histopathological diagnosis by polymerase chain reaction (PCR).Methods: In this study 718 lymph node (LN) biopsies were retrieved, of which 161 were diagnosed as TBL (histopathological evidences). PCR technique was performed for all 161 positive samples to detect the IS6110 sequence of M. tuberculosis as well as to obtain the sensitivity and specificity of morphological diagnosis.Results: Out of 161 specimens 135 (84%) were found to be positive with PCR, the remaining 26 (16%) were negative.Conclusions: Although PCR indicated high sensitivity it can’t be a substitute for conventional histopathology in the diagnosis of tuberculous lymphadenitis in tissue

A Symmetry Chaotic Model with Fractional Derivative Order via Two Different Methods

In this article, we have investigated solutions to a symmetry chaotic system with fractional derivative order using two different methods—the numerical scheme for the ABC fractional derivative, and the Laplace decomposition method, with help from the MATLAB and Mathematica platforms. We have explored progressive and efficient solutions to the chaotic model through the successful implementation of two mathematical methods. For the phase portrait of the model, the profiles of chaos are plotted by assigning values to the attached parameters. Hence, the offered techniques are relevant for advanced studies on other models. We believe that the unique techniques that have been proposed in this study will be applied in the future to build and simulate a wide range of fractional models, which can be used to address more challenging physics and engineering problems

An unusual case of a patient who lost his native kidneys and renal allograft from cholesterol crystal emboli

Cholesterol crystal emboli (CCE) syndrome involving native kidneys is an underdiagnosed condition. CCE is rare in renal allografts. It may present with acute kidney injury, but usually not acute graft loss. CCE should be considered in patients with a history of atherosclerosis and an invasive arterial procedure who present with acute or chronic renal allograft dysfunction. Therapy for CCE is mainly supportive and carries a high rate of mortality. To the best of our knowledge, this is the first reported case of a patient who lost his native kidneys and renal allograft due to CCE arising from his own vasculature

Correspondence: Cytotoxicity of Vitex trifolia leaf extracts on MCF-7 and Vero cell lines

Abstract Pharmacological and preventive properties of Vitex trifolia leaf extracts are well known, but the anticancer activity of methanol and petroleum ether extracts of Vitex trifolia leafs on human breast cancer cells have not been explored so far. Therefore, the present study was designed to investigate the cytotoxic activities of these extracts against MCF-7 and Vero cell line. Cells were exposed to 125 to 500 μg/ml of the extracts of Vitex trifolia for 72 h. Post-treatment, percent cell viability was studied by 3-(4, 5-dimethylthiazol-2yl)-2, 5-biphenyl tetrazolium bromide (MTT) assays. The results showed that petroleum ether and methanol extracts significantly reduced cell viability of MCF-7 cells in a concentration dependent manner. Concentrations of 125 μg/ml and above of petroleum ether and 500 μg/ml of methanol extract were found to be cytotoxic in MCF-7 cells. Cell mortality at 125, 250 and 500 μg/ml of petroleum ether extract was recorded as 98.80%, 93.40% and 87.75% respectively, whereas at 125, 250 and 500 of methanol extract values were 79.98%, 75.70% and 70.25%, respectively by MTT assay. MCF-7 and Vero cells exposed to 125, 250 and 500 μg/ml. The data revealed that the treatment with petroleum ether and methanol of Vitex trifolia leaf extract induced cell death in MCF-7 cells. Meanwhile the same extract showed a moderate inhibition against Vero cell lines. It may be concluded that Vitex trifolia can cause cell death in MCF-7 cancer cells, which can be considered as a promising chemotherapeutic agent in breast cancer treatment

Effect of different extraction techniques on yield and quality of essential oils from rhizomes of Cyperus Rotundus

Medicinal plants play an important role as useful resources in producing new and safer drugs for the treatment of various diseases. The objective of this study was to compare the yield, chemical composition and antimicrobial activity of essential oils (EOs) obtained by two different techniques from rhizomes of genius Cyperus of which C. rotundus (Family: Cyperaceae) belongs to. The EOs was obtained by Steam Distillation (SD) and Hydrodistillation (HD). The chemical compositions were analyzed by Gas Chromatography-Mass Spectroscopy (GC-MS). The antimicrobial activity was tested by disc diffusion method against four microbes namely; Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and Candida albicans. The oil content was 0.18% and 0.27% (v/w) for HD and SD, respectively. The GC-MS analysis led to identification of 71 and 74 components, respectively. The dominant compounds for HD were: 3-Hydroxy-2-(2-methylcyclohex-1-enyl) propionaldehyde (11.20%); 2-cyclohexene-1-1one, 3-methyl-6(1-methyl-31) (8.23%) and 1,4-methanoazulene-9-methanol (5.43%). Whereas for SD were: 3-Hydroxy-2-(2-methylcyclohex-1enyl) propionaldehyde (12.94%), Tricyclo [6.3.0.0(2,4) undec-8ene,3,3,7,11-tetramethyl-(6,48%), 1-Oxaspiro[2.5]octane,5,5-dimethyl-4-(3-methyl-1,3-butan dienyl)- (5.66%) and 4,8,13-Cyclotetradecatriene-1,3-diol,1,5,9-diol,1,5,9-trimethyl-12-(1-methylethyl) -(5.57%). The antimicrobial activities of the oils against tested microorganism were extremely broad, the inhibition zones ranged between 10 and 17 mm. For HD oil, the Candida was the most sensitive to the oil (16 mm) and S. aureus was the most resistant (10 mm). Whereas, for SD oil, the S. aureus was the most sensitive (17 mm) while K. pneumoniae and C. albicans were the most resistance (12 mm). In conclusion, the results obtained from this study proved that the extraction technique is one of the main factors that can affect in the EOs yield, constituents and biological activities. Moreover, the results suggest that the EOs of C. rotundus could be a potential source of antimicrobial ingredients for food and pharmaceutical industries. Therefore, a wide bioassay against more microbes, isolation and identification of bioactive compounds would be an interesting line of inquiry for the further studies

Structure, functions, performance and gaps of event-based surveillance (EBS) in Sudan, 2021: a cross-sectional review

Abstract Background Event-based surveillance (EBS) is an essential component of Early Warning Alert and Response (EWAR) as per the International Health Regulations (IHR), 2005. EBS was established in Sudan in 2016 as a complementary system for Indicator-based surveillance (IBS). This review will provide an overview of the current EBS structure, functions and performance in Sudan and identify the gaps and ways forward.  Methods The review followed the WHO/EMRO guidelines and tools. Structured discussions, observation and review of records and guidelines were done at national and state levels. Community volunteers were interviewed through phone calls. Directors of Health Emergency and Epidemic Control, surveillance officers and focal persons for EBS at the state level were also interviewed. SPSS software was used to perform descriptive statistical analysis for quantitative data, while qualitative data was analysed manually using thematic analysis, paying particular attention to the health system level allowing for an exploration of how and why experiences differ across levels. Written and verbal consents were obtained from all participants as appropriate. Results Sudan has a functioning EBS; however, there is an underestimation of its contribution and importance at the national and states levels. The link between the national level and states is ad hoc or is driven by the need for reports. While community event-based surveillance (CEBS) is functioning, EBS from health facilities and from non-health sectors is not currently active. The integration of EBS into overall surveillance was not addressed, and the pathway from detection to action is not clear. The use of electronic databases and platforms is generally limited. Factors that would improve performance include training, presence of a trained focal person at state level, and regular follow-up from the national level. Factors such as staff turnover, income in relation to expenses and not having a high academic qualification (Diploma or MSc) were noticed as inhibiting factors. Conclusion The review recommended revisiting the surveillance structure at national and state levels to put EBS as an essential component and to update guidelines and standard operation procedures SOPs to foster the integration between EBS components and the overall surveillance system. The need for strengthening the link with states, capacity building and re-addressing the training modalities was highlighted
