Assessment of microbial diversity under arid plants by culture-dependent and culture-independent approaches

In this work, microbial community structure of two distinct arid plants like ker (Capparis deciduas) and pearl millet (Pennisetum glaucum) was assessed and defined by culture-dependent and cultureindependent approaches on the basis of 16S rRNA and random amplified polymorphic DNA (RAPD) analysis. The average Jaccard’s similarity coefficient values for cultivated bacteria that is within ker and pearl millet rhizosphere were 0.701 and 0.707, respectively, for non-rhizosphere of ker and pearl millet 0.739 and 0.762, respectively, and for non-cultivable bacteria under ker (0.519) and under pearl millet (0.534). Both culture- dependent and culture-independent methods indicated that in arid crops, microbial diversity is more influenced by soil type rather than plant type and lower Jaccard value for metagenome showed that whole community harbours more diversity because of different microflora than cultivated only. Salinity and temperature tolerance study of bacteria indicated that ker rhizosphere harbours more salinity and temperature tolerant bacteria.Keywords: Random amplified polymorphic DNA (RAPD), ribotyping, Thar Desert, microbial diversity, 16S rRNA.African Journal of Biotechnology Vol. 12(40), pp. 5860-586

The impact of non-steroidal anti-inflammatory drugs use in elderly cardiovascular patients: an observational study from tertiary care in South India

Background: Long-term use of NSAIDs, by patients having cardiovascular conditions, has shown to increase the risk of cardiovascular events and increased risk of death. Hence, the study was conducted to determine the complications related to NSAID use by the elderly patients with cardiovascular disease (CVD).Methods: The study was a single-center prospective observational study conducted November 2017 to October 2018. Elderly patients (>60 years) suffering from various CVDs and reported NSAID intake daily for at least one month were included. A questionnaire included demographic, treatment related history and complete details of NSAIDs intake including nature, dose, indication, source etc. The same questionnaire was again filled at the end of one-year follow-up.Results: A total of 100 participants were included in the study. The mean age was 72±8.6 years. Majority of the patients (93%) had hypertension, and 69% of the patient had previous MI.  Five NSAIDs (diclofenac, ibuprofen, mefenamic acid, naproxen, and ketorolac) were used routinely. At least one over the counter NSAID used was reported by 86%, 57% were prescribed at least one NSAIDs by their orthopaedics and physicians. At the end of 1-year follow-up, authors found that 71% had MI (2% increase), 4% developed reinfarction, 20% had severe left ventricular failure (4% increase), 7% had atrial fibrillation (1% increase), and 2% patients died and 63% patients reported raise in systolic blood pressure by 5mmHg.Conclusions: High prevalence of concomitant NSAID use among elderly CVD patients, which might be contributing towards increase in CVS morbidity and mortality

A Novel Method for Ultrasonic Imaging of Flaws in Coarse Grain Austenitic Stainless Steels

Ultrasonic detection and imaging of flaws in thick coarse grained austenitic stainless steel components is challenging due to very high scattering. Spectral and wavelet transform based methods have been traditionally applied to reduce the noise to detect flaws. We propose a novel ensemble empirical mode decomposition based signal processing method for adaptive detection of flaws in coarse grained austenitic stainless steel. We have analyzed ultrasonic signals obtained from stainless steel specimens of different grain size (30-200 µm) with and without flaws. The ultrasonic signals lie in two different scattering regimes with wavelength to grain size ratio of 1.8 (near stochastic scattering) to 3 (far Rayleigh scattering). The analysis gave an idea to use particular numbers of intrinsic mode functions (IMFs) in conjunction with minimization approach for the reconstruction of ultrasonic signal. We have verified the usefulness of this method by analyzing the signals obtained from 200 µm grain size specimen with artificial defects. The proposed method has been successfully employed for adaptive detection of flaws in a 50 mm thick coarse grain austenitic stainless steel specimen and for imaging of flaws

Purple urine bag syndrome- changing hue!

Purple Urine Bag Syndrome (PUBS) is a unique disease entity characterised by purple discoloration of urine secondary to recurrent urinary tract infections with indigo and indirubin producing bacteria and is predominantly seen in constipated, chronically debilitated and catheterised women with alkaline urine. This syndrome indicates underlying recurrent urinary tract infections (UTIs) associated with higher incidence of mortality and morbidity than urinary tract infection alone without this occurrence. This article is about an elderly hypothyroid woman with PUBS and reviews the need to be aware of this entity

Improved Rate-Energy Trade-off For SWIPT Using Chordal Distance Decomposition In Interference Alignment Networks

This paper investigates the simultaneous wireless information and power transfer (SWIPT) precoding scheme for K-user multiple-input-multiple-output (MIMO) interference channels (IC), for which interference alignment (IA) schemes provide optimal precoders to achieve full degrees-of-freedom (DoF) gain. However, harvesting RF energy simultaneously reduces the achievable DoFs. To study a trade-off between harvested energy and sum rate, the transceiver design problem is suboptimally formulated in literature via convex relaxations, which is still computationally intensive, especially for battery limited nodes running on harvested energy. In this paper, we propose a systematic method using chordal distance (CD) decomposition to obtain the balanced precoding, which improves the trade-off. Analysis shows that given the nonnegative value of CD, the achieved harvested energy for the proposed precoder is higher than that for perfect IA precoder. Moreover, energy constraints can be achieved, while maintaining a constant rate loss without losing DoFs via tuning the CD value and splitting factor. Simulation results verify the analysis and add that the IA schemes based on max-SINR or mean-squared error are better suited for SWIPT maximization than subspace or leakage minimization methods

Epidemiološka tipizacija bakterije Staphylococcus aureus na osnovi DNA polimorfizma duljine restrikcijskoga fragmenta gena coa

Twenty one Staphylococcus aureus isolates of bovine mastitic milk origin from herds at different locations were analysed for their coa gene products and RFLP patterns. One of the isolates was coa gene deficient whereas the rest revealed polymorphism in the coa gene. The isolates revealed three different types of coa gene products (600, 680 or 850 bp) and three distinct RFLP patterns were obtained with AluI digests of PCR products. Amplicons of 600 bp produced only one fragment of 300 bp (Pattern I), amplicons of 680 bp produced two fragments of 210 and 260 bp (pattern II) and amplicons of 850 bp produced 3 bands at 170, 290 and 390 bp (pattern III). It was concluded that not all the S. aureus isolates possessed the coa gene, the coa genotype was location-specific and this character of the isolates can be used in epidemiological investigations.Dvadeset i jedan izolat bakterije Staphylococcus aureus iz mlijeka krava s upalom vimena iz različitih stada bio je analiziran na proizvode njezina gena coa i polimorfizam duljine restrikcijskih fragmenata (PDRF). U jednom izolatu nije bio dokazan gen coa dok je u ostalim ustanovljen polimorfizam u tom genu. Izolati su pokazali tri različita tipa proizvoda gena coa (600, 680 ili 850 bp), a cijepanjem PCR proizvoda enzimom AluI dobivena su tri različita uzorka PDRF. Amplikoni od 600 bp imali su samo jedan fragment od 300 bp (uzorak I). Amplikoni od 680 bp pocijepali su se na dva fragmenta, jedan od 210, a drugi od 260 bp (uzorak II). Amplikoni od 850 bp pocijepali su se na tri fragmenta: 170, 290 i 390 bp (uzorak III). Zaključuje se da svi izolati vrste Staphylococcus aureus ne posjeduju gen coa, te da je genotip coa bio specifičan po svojoj lokaciji i da se ta značajka izolata može rabiti u epidemiološkim istraživanjima
