“…Acting as nonenzymatic antioxidant and reducing agent these free thiols are rapidly oxidized after exposure to ROS, forming mixed disulfides and related sulfur-containing acids. In one previous study the loss of total serum thiols was found to correspond to the severity of diabetic microvascular complications and the development of DPN [24], and our current results support that finding.…”

This study investigated the relationship between serum xanthine oxidase (XOD) activity and the occurrence of diabetic peripheral neuropathy (DPN) in type 2 diabetes mellitus (T2DM) patients. Serum XOD activity, ischemia-modified albumin (IMA), uric acid (UA), albumin, glycated hemoglobin (HbA1c), advanced glycation end products (AGE), total free thiols, atherogenic index of plasma (AIP), and body mass index (BMI) were measured in 80 T2DM patients (29 with and 51 without DPN), and 30 nondiabetic control subjects. Duration of diabetes, hypertension, medication, and microalbuminuria was recorded. Serum XOD activities in controls, non-DPN, and DPN were 5.7 ± 2.4 U/L, 20.3 ± 8.6 U/L, and 27.5 ± 10.6 U/L (p < 0.01), respectively. XOD activity was directly correlated to IMA, UA, BMI, HbA1c, and AGE, while inversely correlated to serum total free thiols. A multivariable logistic regression model, which included duration of diabetes, hypertension, AIP, HbA1c, UA, and XOD activity, revealed HbA1c [OR = 1.03 (1.00–1.05); p = 0.034] and XOD activity [OR = 1.07 (1.00–1.14); p = 0.036] as independent predictors of DPN. Serum XOD activity was well correlated to several other risk factors. These results indicate the role of XOD in the development of DPN among T2DM patients.

“…Following this fundamental need to counter antibiotic resistance, one way is to search for new sources having possibilities for antibiotic-producing microorganisms. Soil is the prominent source from where hundreds of antibiotic-producing organisms have been isolated during the last five decades (Khamna et al 2009;Hossain and Rahman 2014;Amin et al 2015). Recently workers have started to explore other sources such as oceans (Wu et al 2014).…”

Cow dung, an excreta of bovine animal, is a cheap and easily available bioresource on our planet. Many traditional uses of cow dung such as burning as fuel, mosquito repellent and as cleansing agent are already known in India. Cow dung harbours a diverse group of microorganisms that may be beneficial to humans due to their ability to produce a range of metabolites. Along with the production of novel chemicals, many cow dung microorganisms have shown natural ability to increase soil fertility through phosphate solubilisation. Nowadays, there is an increasing research interest in developing the applications of cow dung microorganisms for biofuel production and management of environmental pollutants. This review focuses on recent findings being made on cow dung that could be harnessed for usage in different areas such as medicine, agriculture and industry.

“…Biological control against spoilage organisms currently represents a fast-growing sector in the crop protection and food industry [1]. Fermentates, i.e., numerous components produced during fermentations by a variety of microorganisms, are referred to as 'biocontrol' as they exhibit antibiosis to pathogenic (spoilage) microorganisms [2,3].…”

“…Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and in its shape, it resembles filamentous fungi. Streptomyces species are the source of thousands of bioactive compounds used in biological control [2]. The first stage for the downstream processing is separation of microbial cells and other insoluble materials from the fermentation broth by filtration or centrifugation.…”

Artificial neural networks (ANNs) have been used to dynamically model cross-flow microfiltration of Streptomyces hygroscopicus fermentation broths. The aim is to predict permeate flux as a function of temperature, feed flow, transmembrane pressure and processing time. Dynamic modeling of microfiltration performance of complex systems (such as broths) is very important for design of new processes and better understanding of the present. The results of ANN model analysis suggest that the coefficients of the determination have high values. The application of the Bayesian regularization gave better results to the performance of the neural network compared to the Levenberg-Marquet algorithm. The optimal number of neurons in the hidden layer is eight. Analysis of the absolute relative error showed excellent permeate flux estimates for 100 % of the data points, with an error less than 5 % for the data obtained during microfiltration in the presence of a turbulence promoter. Whilst in the case of microfiltration without turbulence promoter 90 % of predictions have an error less than 10 %. The results of applying the concept of neural networks in the dynamic modeling of microfiltration of Streptomyces hygroscopicus fermentative broths with and without a turbulence promoter clearly show the validity of proposed method for simulation and prediction of microfiltration experimental results.
