    The survival rate of cancer patients has greatly increased over the last 20 years. However, to achieve this result, a considerable price has been paid in terms of the side effects associated with the intensive anticancer treatment. The most common adverse effect is cardiotoxicity which may compromise the clinical effectiveness of chemotherapy, affecting the patient's survival and quality of life independently of the oncological prognosis. There are 2 types of cardiac toxicities, type I which is more serious and result in permanent damage to the myocardium and type II which is usually reversible. Chemotherapies varies in their incidence of inducing cardiomyopathy, and the onset which may occur acutely (during or shortly after treatment), sub-acutely (within days or weeks after completion of chemotherapy) or chronically (weeks to months after drug administration). Cardiac events associated with chemotherapy may consist of mild blood pressure changes, thrombosis, Electrocardiographic (ECG) changes, arrhythmias, myocarditis, pericarditis, myocardial infarction, cardiomyopathy, cardiac failure (left ventricular failure), and congestive heart failure (CHF). The risk for such effects depends upon: cumulative dose, rate of drug administration, mediastinal radiation, advanced age, younger age, female gender, pre-existing heart disease and hypertension. Serial measurements of LVEF and fractional shortening are the most common indices monitored to assess left ventricular systolic function and cardiotoxicity. This can be achieved by 2-dimensional, M-mode and color Doppler echocardiographic examination; also Cardiac troponins as a biological marker for myocardial damage can be used for monitoring in patients received anthracyclines. Angiotensin-converting enzyme (ACE) inhibitors (ACEIs) have been shown to slow the progression of left ventricular dysfunction in several different clinical settings, including anthracycline-induced cardiomyopathy. Carvedilol and probably with anti-oxidants like Probucol and vitamin E benefits also

    Web crawler visits websites for the purpose of indexing. The dynamic nature of today’s web makes the crawling process harder than before as web contents are continuously updated. In addition, crawling speed is important considering tsunami of big data that need to be indexed among competitive search engines. This research project is aimed to provide survey of current problems in distributed web crawlers. It then investigate the best crawling speed between dynamic globally unique identifiers (GUIDs) and the traditional static identifiers (IDs). Experiment are done by implementing Arachnot.net web crawlers to index up to 20000 locally generated URLs using both techniques. The results shown that URLs crawling time can be reduced up to 7% by using GUIDs technique instead of using IDs

    Synthesis of Mixed Ligand Complexes of M(II) Dithiocarbamato Derivative and 2,2'-bipyridyl and Study their Cytotoxic Effect Against HepG2 Cell Line in vitro

    Mixed ligand of Co and Ni (II) complexes were prepared from [5-(p-nitrophenyl)-4/-phenyl-1,2,4-triazole-3-dithiocarbamato hydrazide](TRZ.DTC) as primary ligand and 2,2'-bipyridyl (bipy) as a co-ligand with metal salts. These complexes were analytically and spectroscopically characterized in solid state by elemental analyses, flame atomic absorption, magnetic susceptibility and molar conductance measurements, as well as by UV–Vis and FTIR spectroscopy. Infrared, ultra violet spectra reveal a bidentate coordination of the two ligands with metal ions 1:1:1 mole ratio. Room temperature magnetic moments and solid reflectance spectra data indicate paramagnetic complexes with five-coordinate square pyramidal geometry for nickel (II) complex, while six-coordinate octahedral geometry for cobalt (II) complex in solid state. The mixed ligand and its respective complexes were screened for cytotoxicity assay on human HepG2 cell line using cis-Pt drug as a control positive following the cell culture method for 3 days after treatment with the tested compounds using eight different concentrations. The bioassay results showed good inhibition activity of these synthetic compounds especially Ni (II) complex on selected cell lines comparable with standard drug

    Background: Meteorin-like, is an innovative adipokine, that exhibits elevated expression within adipose tissue and confers advantageous effects upon energy metabolism. Nevertheless, current research pertaining to circulating Meteorin-like levels in obesity remains limited and incongruent. Thus, the objective of this study was to assess Metrnl serum concentrations among adult individuals with pre-diabetes and newly diagnosed type 2 diabetes mellitus and examine its correlation with glucose, HbA1C, and lipid metabolism. Subjects and Methods: The case-control study incorporated 120 subjects, who were then segregated into three distinct groups, namely control (n = 60), pre-diabetes (n = 30), and newly diagnosed type 2 diabetes mellitus patient’s (n = 30). The quantification of serum Meteorin-like concentrations was undertaken by employing an enzyme-linked immunosorbent assay. Results: The data of the current study demonstrates a significant increase in the concentration of Meteorin-like protein in individuals with newly diagnosed type 2 diabetes mellitus patients as compared to those without the condition (p ≤ 0.001). A positive correlation between METRNL and various metabolic parameters, such as BMI, FBS, HbA1C, TC, TG, and LDL-C, was observed using the Pearson correlation coefficient. Conversely, a negative correlation was observed between METRNL and HDL-C as well as VLDL-C. Conclusions: The present study has revealed that serum Meteorin-like levels were found to be elevated in both individuals having newly diagnosed type 2 diabetes mellitus patients and pre-diabetes. Furthermore, the association between serum Meteorin-like levels and lipid profile was observed to be dependent. These findings strongly suggest that the modification of circulating Meteorin-like levels may serve as a promising biomarker for the prognosis of type 2 diabetes mellitus

    Sustainable manufacturing and parametric analysis of mild steel grade 60 by deploying CNC milling machine and Taguchi method

    Design and manufacturing are the key steps in the sustainable manufacturing of any product to be produced. Within the perspective of injection molds production, increased competitiveness and repeated changes in the design require a complete optimized manufacturing process. Local and minor improvements in the milling process do not generally lead to an optimized manufacturing process. The goal of the new geometry and parametric analysis of the mould is to reduce the quality issues in mild steel grade 60. In this explicit research, the surface roughness (smoothness) of indigenously produced injection moulds in the local market in Pakistan is investigated. The CNC milling machine (five-axis) is used for the manufacturing of an injection mould, and the Taguchi method of the design of the experiment is applied for parameters optimization. Hence, the overall process is assisted in balancing the milling machine parameters to trim down the surface roughness issue in mild steel moulds and increase their sustainability. The spindle speed (rpm), the depth of cut (mm), and the feed rate (mm/rev) are considered as input variables for process optimization, and the experiments are performed on mild steel grade 60. It is deduced that the combination of a spindle speed of 800 rpm, feed rate of 10 mm/rev and depth of cut of 0.5 mm is the best case in case of minimum surface roughness, which leads to sustainable products. It is also deduced from ANOVA, that the spindle speed is a factor that affects the surface roughness of mild steel products, while the feed rate turns out to be insignificant

    ABSTRACT Intensive cropping has resulted-in wide spread deficiency of nutrients in most of the soils and situation is becoming more serious because of a increase in the use of high priced chemical fertilizers and their negative influence on the environment. Exploitation of biological intervention mainly phosphate solublizing bacteria (PSB) has attracted great attention, as they have enormous potential in providing soil phosphorus for plant growth, by increasing the availability of accumulated phosphate through solubilization. A field experiment was conducted to investigate the effect of Rhizobium and Bacillus, alone and in combination on the yield parameters of wheat. Uniform dose of N and K (160 and 60 kg ha ), grain protein (11.84%) and 1000 grain weight (62 g) were higher in co-inoculation of Rhizobium and Bacillus. It was also recorded that coinoculation of Rhizobium and Bacillus improved the grain yield up to 17.5% as compared to control. In single inoculation Bacillus gave better result and showed an increase of 7.7% in grain yield. Phosphorus uptake by grains (25.29 kg ha -1 ) was maximized by co-inoculation followed by Bacillus inoculation. Available phosphorus in post harvest sample of soil was recorded (16.27 mg kg -1 ) which was significantly higher than all other treatments. Results clearly demonstrated that co-inoculation of Rhizobium and Bacillus sp enhanced the availability of phosphorus and exert positive effect on the growth and yield of crop

    Background and Purpose: The presence of aortic atherosclerosis is an independent risk factor for secondary stroke. The present study was designed to have an initial exploration of the correlation between the load and extent of aortic atheroma (AA) and initial stroke severity or clinical outcome 3 months after stroke. Methods: Cardiac-gated chest tomography (CGCT) was used to detect and measure AA in patients with acute ischemic stroke as shown by our group in prior prospective studies and this is part four sub-exploratory study of the same cohort. The National Institute of Health Stroke Scale (NIHSS) was used to assess the initial stroke severity, and the modified Rankin Scale (mRS) was used to assess 3-month outcome. Results: Thirty-two patients underwent CGCT for evaluation of AA, and 21 were found to have AA. AA was more prevalent in patient with NIHSS >6 (14/17 versus 7/15, p-value 0.03). Applying the multiple logistic regression and propensity score adjustment (using the propensity of having AA given the baseline features as covariates) showed a non-significant trend that AA is three times more likely to be associated with NIHSS >6 (p = 0.08, OR 3.08, 95% CI 0.94–13.52). There was no evidence of association of AA with 3-month functional outcome (mRS): 11/14 (78.6%) mRS >1 had AA, and 10/18 (55.5%) of those with mRS ≤1 had AA (p = 0.27). Conclusion: In our current study with limited sample number and exploratory nature, the presence of AA on CGCT with acute ischemic stroke patients may be associated with worse neurological deficit at presentation. There was no evidence of association with 3-month functional outcome using the mRS
