Diverse Application of Arthrospira Potential Herb

Spirulina is a photosynthetic, filamentous, spiral-shaped, multicellular and green-blue microalga. The two most important species of which are Spirulina maxima and Spirulina platensis. It is a microalga belonging to Chyanophyceae class. Its chemical composition includes proteins (55%-70%), carbohydrates (15%-25%), essential fatty acids (18%) vitamins, minerals and pigments like carotenes, chlorophyll a and phycocyanin. Used in food and cosmetic industries. Spirulina is considered as an excellent food, lacking toxicity and having corrective properties against viral attacks, anemia, tumor growth and malnutrition. It has been reported that the use of these microalgae as animal food supplement implies enhancement of the yellow coloration of skin and eggs yolk in poultry and flamingos, growth acceleration, sexual maturation and increase of fertility in cattle. Spirulina can play an important role in human and animal nutrition, environmental protection through wastewater recycling and energy conservation. Spirulina is rich in proteins (60-70%), vitamins and minerals used as protein supplement in diets of undernourished poor children in developing countries. One gram of Spirulina protein is equivalent to one kilogram of assorted vegetables. The mass cultivation of Spirulina is achieved both in fresh water and waste water. Spirulina grown in clean waters and under strictly controlled conditions could be used for human nutrition. The micro alga grown in waste water is used as animal feed and provide a source of the fine chemicals and fuels. The waste water system is highly applicable in populated countries like India where wastes are generated in high quantities and pose environmental problem. It has high levels of vitamins, minerals, phenolics, essential fatty acids, amino acids and pigments. Furthermore, the development of new protein sources to supply the shortage of this nutrient is an urgent need, and protein from S. platensis plays an important role . In this sense, extraction processes that allow maximum protein yield and total utilization of biomass is an urgent need, and ultrasonic waves have proven to be an effective extraction technique  Keywords: food, microalgae, nutrition, Spirulina, Flamingos etc

Beta-Lactamases in a Tertiary Care Hospital: "Biological Quake" Knocking at the Door

Background: Antimicrobial resistance due to the production of extended-spectrum β-lactamases (ESBLs), AmpC β-lactamases, and metallo-β-lactamases (MBLs) have emerged as a major health catastrophe limiting antibiotic treatment options. Therefore, this study was conducted to assess the current level of ESBLs, AmpC β-lactamases, and MBLs- producing bacteria and their antibiotic susceptibility profile in a Nepalese hospital. Methods: This was a cross-sectional study carried out among the inpatients of Medicare National Hospital, Kathmandu from April to September 2015. During the study period, a total of 589 specimens (urine, sputum, blood, pus, body fluids, throat swab, central venous catheter - CVC tip) collected aseptically from the admitted patients were selected in the study. The collected specimens were processed, and the isolated organisms were identified following the standard microbiological methods. ESBL was detected by standard combination disc method and double-disc synergy test.  Results: Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterococcus faecalis, and Candida albicans were the common microbial agents isolated from hospital-admitted patients. Among total 84 Gram-negative bacteria tested for ESBL-production, 23 (27.4%) isolates were ESBL-producers. ESBL production was seen in 32.3% of Escherichia coli and 28.6% of Klebsiella pneumoniae isolates. Similarly, MBL production was identified in 28.6% of Pseudomonas aeruginosa, and 6.5% of Escherichia coli. Likewise, 3.2% of Escherichia coli were AmpC β-lactamase-producers. The ESBL-producing bacteria showed less susceptibility to different antibiotics as compared to non-ESBL-producers. Consistent results were found with different methods like combination disk method, MASTDISKSTM ID AmpC and ESBL disk, Ezy MICTM Strip (MIX+/MIX) method, and triple ESBL detection Ezy MICTM strips employed for the detection of ESBL and AmpC. Conclusions: ESBL was commonly seen in Escherichia coli while MBL in Pseudomonas aeruginosa. Routine monitoring of these kinds of resistance phenotypes following appropriate methods is essential for the proper treatment of patients.

Effect of Simulated Heat Stress on Digestibility, Methane Emission and Metabolic Adaptability in Crossbred Cattle

The present experiment was conducted to evaluate the effect of simulated heat stress on digestibility and methane (CH4) emission. Four non-lactating crossbred cattle were exposed to 25°C, 30°C, 35°C, and 40°C temperature with a relative humidity of 40% to 50% in a climatic chamber from 10:00 hours to 15:00 hours every day for 27 days. The physiological responses were recorded at 15:00 hours every day. The blood samples were collected at 15:00 hours on 1st, 6th, 11th, 16th, and 21st days and serum was collected for biochemical analysis. After 21 days, fecal and feed samples were collected continuously for six days for the estimation of digestibility. In the last 48 hours gas samples were collected continuously to estimate CH4 emission. Heat stress in experimental animals at 35°C and 40°C was evident from an alteration (p<0.05) in rectal temperature, respiratory rate, pulse rate, water intake and serum thyroxin levels. The serum lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase activity and protein, urea, creatinine and triglyceride concentration changed (p<0.05), and body weight of the animals decreased (p<0.05) after temperature exposure at 40°C. The dry matter intake (DMI) was lower (p<0.05) at 40°C exposure. The dry matter and neutral detergent fibre digestibilities were higher (p<0.05) at 35°C compared to 25°C and 30°C exposure whereas, organic matter (OM) and acid detergent fibre digestibilities were higher (p<0.05) at 35°C than 40°C thermal exposure. The CH4 emission/kg DMI and organic matter intake (OMI) declined (p<0.05) with increase in exposure temperature and reached its lowest levels at 40°C. It can be concluded from the present study that the digestibility and CH4 emission were affected by intensity of heat stress. Further studies are necessary with respect to ruminal microbial changes to justify the variation in the digestibility and CH4 emission during differential heat stress

Genetic diversity and population structure analyses in barley (Hordeum vulgare) against corn-leaf aphid, Rhopalosiphum maidis (Fitch)

Corn-leaf aphid (CLA), Rhopalosiphum maidis (Fitch) (Hemiptera: Aphididae) is a serious economic pest of barley worldwide. Breeding for aphid resistance in plants is considered a cost-effective and environmentally safe approach for aphid control, compared to the use of chemical pesticides. One of the challenges in breeding for aphid resistance is the identification of resistant plant genotypes, which can be achieved through the use of molecular markers. In the present study, a set of aphid specific 10 simple-sequence repeats (SSR) markers were used to investigate genetic diversity and population structure analyses in 109 barley genotypes against R. maidis. Three statistical methods viz., multivariate hierarchical clustering based on Jaccard’s similarity coefficient, principal coordinate analysis (PCoA) and the Bayesian approach were utilized to classify the 109 barley genotypes. The analyses revealed four subpopulations i.e., SubPop1, SubPop2, SubPop3 and SubPop4 with 19, 46, 20 and 24 genotypes including admixtures, respectively and represented 17.43%, 42.2%, 18.34% and 22.01% genotypes of the total population size, respectively. The studied SSR markers produced 67 polymorphic bands, with an average of 6.7 and ranging from 3 to 12 bands. Heterozygosity (H) was found to be highest in SSR28 (0.64) and lowest in SSR27 (0.89). The observed genetic diversity index varied from 0.10 to 0.34 (with an average of 0.19). Major allele frequency varied from 74.08% to 94.80%. On an average, 87.52% of the 109 barley genotypes shared a common major allele at any locus. Based on the Aphid Infestation Index (AII), only 2 genotypes were found to be resistant against CLA. SubPop2 also had lowest mean aphid population (28.83), widest genetic similarity index (0.60-1.00) and highest genetic similarity coefficient (0.82), which highlighted its potential for inclusion in future CLA resistance breeding programs

Electrocardiogram abnormalities and renal impairment in patients with type 2 diabetes mellitus: a healthcare facilities-based cross-sectional study in Dang district of Nepal

Aims/Introduction: The global burden of diabetes mellitus is rising substantially, with a further increase in cardiovascular and kidney disease burden. These public health problems are highly prevalent in low- and middle-income countries, including Nepal. However, there is limited evidence on cardiac and renal conditions among patients with type 2 diabetes mellitus. We determined the status of electrocardiogram (ECG) abnormalities and renal impairment among patients with type 2 diabetes mellitus in Nepal. Methods: We carried out a cross-sectional study in Tulsipur Sub-Metropolitan City of Nepal using a multistage stratified sampling technique to recruit patients with type 2 diabetes mellitus. We used World Health Organization stepwise approach to surveillance (WHO STEPS) questionnaires and carried out resting ECG to collect data of 345 patients with type 2 diabetes mellitus. Logistic regression analysis assessed the factors associated with ECG abnormalities and renal impairment. Results: The study showed that 6.1% of participants had major ECG abnormalities (95% confidence interval [CI] 3.8–8.6%), which were associated with hypertension (P = 0.01%) and low socioeconomic status (P = 0.01). The proportion of major and/or minor ECG abnormalities was 47.8% (95% CI 40.5–51%), and were significantly associated with age (odds ratio [OR] 1.04, 95% CI 1.01–1.07), higher education (OR 3.50, 95% CI 1.31–9.33), unemployment (OR 3.02, 95% CI 1.08–8.48), body mass index (OR 1.09, 95% CI 1.02–1.17) and duration of type 2 diabetes mellitus >5 years (OR 2.42, 95% CI 1.19–4.93). The proportion of renal impairment was 3.5% (95% CI 1.5–4.5%) which was associated with older age (OR 1.08, 95% CI 1.00–1.17) and hypertension (OR 12.12, 95% CI 1.07–138.22). Conclusion: A significant proportion of patients with type 2 diabetes mellitus had ECG abnormalities and renal impairment, which were significantly associated with hypertension. Therefore, hypertension management and early screening are essential to prevent future cardiorenal complications among patients with type 2 diabetes mellitus

Association mapping reveals novel genes and genomic regions controlling grain size architecture in mini core accessions of Indian National Genebank wheat germplasm collection

Wheat (Triticum aestivum L.) is a staple food crop for the global human population, and thus wheat breeders are consistently working to enhance its yield worldwide. In this study, we utilized a sub-set of Indian wheat mini core germplasm to underpin the genetic architecture for seed shape-associated traits. The wheat mini core subset (125 accessions) was genotyped using 35K SNP array and evaluated for grain shape traits such as grain length (GL), grain width (GW), grain length, width ratio (GLWR), and thousand grain weight (TGW) across the seven different environments (E1, E2, E3, E4, E5, E5, E6, and E7). Marker-trait associations were determined using a multi-locus random-SNP-effect Mixed Linear Model (mrMLM) program. A total of 160 non-redundant quantitative trait nucleotides (QTNs) were identified for four grain shape traits using two or more GWAS models. Among these 160 QTNs, 27, 36, 38, and 35 QTNs were associated for GL, GW, GLWR, and TGW respectively while 24 QTNs were associated with more than one trait. Of these 160 QTNs, 73 were detected in two or more environments and were considered reliable QTLs for the respective traits. A total of 135 associated QTNs were annotated and located within the genes, including ABC transporter, Cytochrome450, Thioredoxin_M-type, and hypothetical proteins. Furthermore, the expression pattern of annotated QTNs demonstrated that only 122 were differentially expressed, suggesting these could potentially be related to seed development. The genomic regions/candidate genes for grain size traits identified in the present study represent valuable genomic resources that can potentially be utilized in the markers-assisted breeding programs to develop high-yielding varieties

Effect of early tranexamic acid administration on mortality, hysterectomy, and other morbidities in women with post-partum haemorrhage (WOMAN): an international, randomised, double-blind, placebo-controlled trial

Background Post-partum haemorrhage is the leading cause of maternal death worldwide. Early administration of tranexamic acid reduces deaths due to bleeding in trauma patients. We aimed to assess the effects of early administration of tranexamic acid on death, hysterectomy, and other relevant outcomes in women with post-partum haemorrhage. Methods In this randomised, double-blind, placebo-controlled trial, we recruited women aged 16 years and older with a clinical diagnosis of post-partum haemorrhage after a vaginal birth or caesarean section from 193 hospitals in 21 countries. We randomly assigned women to receive either 1 g intravenous tranexamic acid or matching placebo in addition to usual care. If bleeding continued after 30 min, or stopped and restarted within 24 h of the first dose, a second dose of 1 g of tranexamic acid or placebo could be given. Patients were assigned by selection of a numbered treatment pack from a box containing eight numbered packs that were identical apart from the pack number. Participants, care givers, and those assessing outcomes were masked to allocation. We originally planned to enrol 15 000 women with a composite primary endpoint of death from all-causes or hysterectomy within 42 days of giving birth. However, during the trial it became apparent that the decision to conduct a hysterectomy was often made at the same time as randomisation. Although tranexamic acid could influence the risk of death in these cases, it could not affect the risk of hysterectomy. We therefore increased the sample size from 15 000 to 20 000 women in order to estimate the effect of tranexamic acid on the risk of death from post-partum haemorrhage. All analyses were done on an intention-to-treat basis. This trial is registered with ISRCTN76912190 (Dec 8, 2008); ClinicalTrials.gov, number NCT00872469; and PACTR201007000192283. Findings Between March, 2010, and April, 2016, 20 060 women were enrolled and randomly assigned to receive tranexamic acid (n=10 051) or placebo (n=10 009), of whom 10 036 and 9985, respectively, were included in the analysis. Death due to bleeding was significantly reduced in women given tranexamic acid (155 [1·5%] of 10 036 patients vs 191 [1·9%] of 9985 in the placebo group, risk ratio [RR] 0·81, 95% CI 0·65–1·00; p=0·045), especially in women given treatment within 3 h of giving birth (89 [1·2%] in the tranexamic acid group vs 127 [1·7%] in the placebo group, RR 0·69, 95% CI 0·52–0·91; p=0·008). All other causes of death did not differ significantly by group. Hysterectomy was not reduced with tranexamic acid (358 [3·6%] patients in the tranexamic acid group vs 351 [3·5%] in the placebo group, RR 1·02, 95% CI 0·88–1·07; p=0·84). The composite primary endpoint of death from all causes or hysterectomy was not reduced with tranexamic acid (534 [5·3%] deaths or hysterectomies in the tranexamic acid group vs 546 [5·5%] in the placebo group, RR 0·97, 95% CI 0·87-1·09; p=0·65). Adverse events (including thromboembolic events) did not differ significantly in the tranexamic acid versus placebo group. Interpretation Tranexamic acid reduces death due to bleeding in women with post-partum haemorrhage with no adverse effects. When used as a treatment for postpartum haemorrhage, tranexamic acid should be given as soon as possible after bleeding onset.
