Dibutyl phthalate degradation by Paenarthrobacter ureafaciens PB10 through downstream product myristic acid and its bioremediation potential in contaminated soil. CHEMOSPHERE 2024; 352:141359. [PMID: 38309604 DOI: 10.1016/j.chemosphere.2024.141359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 01/30/2024] [Accepted: 01/31/2024] [Indexed: 02/05/2024]
Abstract
Dibutyl phthalate (DBP) is a widely used plasticizer to make plastic flexible and long-lasting. It is easily accessible in a broad spectrum of environments as a result of the rising level of plastic pollution. This compound is considered a top-priority toxicant and persistent organic pollutant by international environmental agencies for its endocrine disruptive and carcinogenic propensities. To mitigate the DBP in the soil, one DBP-degrading bacterial strain was isolated from a plastic-polluted landfill and identified as Paenarthrobacter ureafaciens PB10 by 16S rRNA gene sequence-based homology. The strain was found to develop a distinct transparent halo zone around grown colonies on an agar plate supplemented with DBP. The addition of yeast extract (100 mg/L) as a nutrient source accelerated cell biomass production and DBP degradation rate; however, the presence of glucose suppressed DBP degradation by the PB10 strain without affecting its ability to proliferate. The strain PB10 was efficient in eliminating DBP under various pH conditions (5.0-8.0). Maximum cell growth and degradation of 99.49% at 300 mg/L DBP were achieved in 72 h at the optimized mineral salt medium (MS) conditions of pH 7.0 and 32 °C. Despite that, when the concentration of DBP rose to 3000 mg/L, the DBP depletion rate was measured at 79.34% in 72 h. Some novel intermediate metabolites, like myristic acid, hexadecanoic acid, stearic acid, and the methyl derivative of 4-hydroxyphenyl acetate, along with monobutyl phthalate and phthalic acid, were detected in the downstream degradation process of DBP through GC-MS profiling. Furthermore, in synchronization with native soil microbes, this PB10 strain successfully removed a notable amount of DBP (up to 54.11%) from contaminated soil under microcosm study after 10 d. Thus, PB10 has effective DBP removal ability and is considered a potential candidate for bioremediation in DBP-contaminated sites.

Abstract
Symmetries in a network regulate its organization into functional clustered states. Given a generic ensemble of nodes and a desirable cluster (or group of clusters), we exploit the direct connection between the elements of the eigenvector centrality and the graph symmetries to generate a network equipped with the desired cluster(s), with such a synthetical structure being furthermore perfectly reflected in the modular organization of the network's functioning. Our results solve a relevant problem of designing a desired set of clusters and are of generic application in all cases where a desired parallel functioning needs to be blueprinted.

Abstract
The present study focuses on generating mesopores within H-ZSM-5 (H-Z) zeolite via desilication and dealumination to incorporate Lewis acidic metal, such as Sn, into the framework (Sn4 ZS180 A15 ) to catalyse glucose isomerisation. Sn4 ZS180 A15 possesses enhanced surface area (457 m2 g-1 ), mesopore volume (0.585 cm3 g-1 ) and a high weak-medium to strong acidic sites ratio, compared to parent H-Z (395 m2 g-1 ; 0.174 cm3 g-1 ). DRS-UV-Vis and XPS results corroborate Sn incorporation into the framework of Sn4 ZS180 A15 , based on the absorbance peak around 200-220 nm and peaks appearing at 495.8 and 487.4 eV, respectively. Sn4 ZS180 A15 exhibits higher catalytic activity towards glucose isomerisation in ethanol-water at 110 °C, yielding 44.2 % fructose with 80.0 % selectivity. Conversely, the parent H-Z afforded negligible glucose conversion with a fructose yield of <1 % under identical conditions. Moreover, Sn-incorporated on dealuminated (Sn4 ZS0 A15 ) and desilicated (Sn4 ZS180 A0 ) catalysts give a low yield of fructose (7-10 %), signifying the requirement of the desilication-dealumination process before incorporating Sn into the framework.

Abstract
SETTING Twenty poultry farms in five provinces of Nepal were selected for studying bacterial pathogens and their antimicrobial resistance (AMR) patterns. OBJECTIVE To document the proportion of cloacal swabs collected from 3,230 broiler and 3,230 layer chickens from September to December 2021 that grew isolates of Escherichia coli, Enterococcus spp. and Salmonella spp. along with their AMR patterns. DESIGN This was a cross-sectional descriptive study. RESULTS In broiler birds, Enterococcus spp., Salmonella spp. and E. coli were identified in respectively 36%, 39% and 63% of swabs. In layer birds, Enterococcus spp., Salmonella spp. and E. coli were identified in respectively 31%, 48% and 60% of swabs. For both bird types, there was variation in bacterial prevalence between the regions. For all three bacterial isolates, the lowest antimicrobial resistance was found with amikacin. For the other nine antibiotics tested, >50% of bacterial isolates showed resistance; between 60% and 90% of isolates showed resistance to ciprofloxacin and trimethoprim-sulfamethoxazole. Multidrug resistance ranged from 45% to 46% for Salmonella spp., 37-44% for E. coli and 13-17% for Enterococcus spp. CONCLUSION This study shows that a large proportion of poultry in Nepal are infected with potentially pathogenic bacteria, and these are frequently resistant to commonly used antibiotics. Nepal urgently needs to implement corrective measures.

Abstract
Towards an efficient, low-cost solution to the problem of contamination of groundwater by selenium leached out from earth's mineral crust, a new system is developed using a novel graphene-based nanocomposite membrane. The system not only purified selenium-contaminated groundwater with high degree but also ensured safe disposal of the rejected selenium through algorithmic chemical stabilization in a mineral matrix. All experiments were conducted with live contaminated water from selenium affected area rather than using synthetic solution in a semi-pilot unit involving a largely fouling-free flat sheet cross-flow membrane module. Pure water flux of up to 190 Lm-2h-1(LMH) with 96-97% selenium rejection at an optimum operating pressure of only 14 bar could be achieved. Rejected selenium was stabilized in mineral matrix through chemical coagulation-precipitation using suitable coagulants following prior optimization of the critical operating parameters by Model-based calibration toolbox (MATLAB R2020a). A high degree of stabilization efficiency (99.8%) could be achieved as reflected in an error-index of only 1.13%. For selenium-affected region, the membrane-integrated hybrid treatment system proved to be a potential candidate technology offering safe drinking water at an approximate cost of only 1.77 $/m3 which was found to be affordable to the consumers in subsequent willingness to pay survey.

Abstract
AbstractSilicon wet bulk micromachining is the most widely used technique for the fabrication of diverse microstructures such as cantilevers, cavities, etc. in laboratory as well as in industry for micro-electromechanical system (MEMS) application. Although, increasing the throughput remains inevitable, and can be done by increasing the etching rate. Furthermore, freestanding structure release time can be reduced by the improved undercutting rate at convex corners. In this work, we have investigated the etching characteristics of a non-conventional etchant in the form of hydroxylamine (NH2OH) added sodium hydroxide (NaOH) solution. This research is focused on Si{100} wafer as this orientation is largely used in the fabrication of planer devices (e.g., complementary metal-oxide semiconductors) and microelectromechanical systems (e.g., inertial sensors). We have performed a systematic and parametric analysis without and with 12% NH2OH in 10 M NaOH for improved etching characteristics such as etch rate, undercutting at convex corners, and etched surface morphology. 3D scanning laser microscope is used to measure average surface roughness (Ra), etch depth (d), and undercutting length (l). Morphology of the etched Si{100} surface is examined using optical and scanning electron microscopes. The addition of NH2OH in NaOH solution remarkably exhibited a two-fold increment in the etching rate of a Si{100} surface. Furthermore, the addition of NH2OH significantly improves the etched surface morphology and undercutting at convex corners. Undercutting at convex corners is highly prudent for the quick release of microstructures from the substrate. In addition, we have studied the effect of etchant age on etching characteristics. Results presented in this article are of large significance for engineering applications in both academic and industrial laboratories.

Abstract
Phthalates are a family of reprotoxicant compounds, predominantly used as a plasticizer to improve the flexibility and longevity of consumable plastic goods. After their use these plastic products find their way to the waste disposal sites where they leach out the hazardous phthalates present within them, into the surrounding environment, contaminating soil, groundwater resources, and the nearby water bodies. Subsequently, phthalates move into the living system through the food chain and exhibit the well-known phenomenon of biological magnification. Phthalates as a primary pollutant have been classified as 1B reprotoxicants and teratogens by different government authorities and they have thus imposed restrictions on their use. Nevertheless, the release of these compounds in the environment is unabated. Bioremediation has been suggested as one of the ways of mitigating this menace, but studies regarding the field applications of phthalate utilizing microbes for this purpose are limited. Through this review, we endeavor to make a deeper understanding of the cause and concern of the problem and to find out a possible solution to it. The review critically emphasizes the various aspects of phthalates toxicity, including their chemical nature, human health risks, phytoaccumulation and entry into the food chain, microbial role in phthalate degradation processes, and future challenges.

Abstract
The intricate nature and rigidity of rice straw, particularly the presence of lignin and silica, hinders the catalytic valorization, consequently decreasing the yield of target products. This study reports the concurrent removal of lignin and silica from rice straw to obtain enriched holocellulose, then transforming it to furfural (FUR) and levulinic acid (LA). Interestingly, rice straw in the form of powder displays an improved removal of lignin (51.0%) and silica (92.0%) during ammonia treatment. Encouragingly, adding organic solvents, such as THF, to the aqueous system during the pretreatment of rice straw improves the lignin removal to 60.0%. Upon improving lignin removal to 60%, the obtained holocellulose enriched solid residue yields 71.0% FUR along with 52.0% LA, which is 8 and 4-fold higher than what is obtained with parent rice straw, signifying the importance and the prerequisite of lignin and silica removal from rice straw.

Abstract
The present study focused on developing a stable basic MnOx support for Ru (RuMn) for the efficient oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) in water in the absence of an external base. A series of MnOx supports, synthesized via hydrothermal approach using urea as precipitant, was prepared by thermal treatment at various temperatures (300-800 °C) before doping with Ru. The RuMn-2 (1 wt % Ru, MnOx calcined at 400 °C) possessed a large number of basic sites (1.72 mmol g-1 ) based on CO2 temperature-programmed desorption analysis, affording an FDCA yield of 87 % with a turnover frequency of 22 h-1 . Transmission electron microscopy energy-dispersive X-ray spectroscopy elemental mapping of RuMn-2 showed a high dispersion of Ru over the surface of MnOx, contributing to the efficient HMF oxidation. Moreover, X-ray diffraction, X-ray photoelectron spectroscopy, and H2 temperature-programmed reduction indicated that the predominant MnO2 phase (ϵ-MnO2 ) played a vital role in HMF oxidation. RuMn-2 was recyclable for up to four runs without significant loss in the activity and retained its structural integrity.

Abstract
A critical investigation into arsenic uptake and transportation, its phytotoxic effects, and defense strategies including complex signaling cascades and regulatory networks in plants. The metalloid arsenic (As) is a leading pollutant of soil and water. It easily finds its way into the food chain through plants, more precisely crops, a common diet source for humans resulting in serious health risks. Prolonged As exposure causes detrimental effects in plants and is diaphanously observed through numerous physiological, biochemical, and molecular attributes. Different inorganic and organic As species enter into the plant system via a variety of transporters e.g., phosphate transporters, aquaporins, etc. Therefore, plants tend to accumulate elevated levels of As which leads to severe phytotoxic damages including anomalies in biomolecules like protein, lipid, and DNA. To combat this, plants employ quite a few mitigation strategies such as efficient As efflux from the cell, iron plaque formation, regulation of As transporters, and intracellular chelation with an array of thiol-rich molecules such as phytochelatin, glutathione, and metallothionein followed by vacuolar compartmentalization of As through various vacuolar transporters. Moreover, the antioxidant machinery is also implicated to nullify the perilous outcomes of the metalloid. The stress ascribed by the metalloid also marks the commencement of multiple signaling cascades. This whole complicated system is indeed controlled by several transcription factors and microRNAs. This review aims to understand, in general, the plant-soil-arsenic interaction, effects of As in plants, As uptake mechanisms and its dynamics, and multifarious As detoxification mechanisms in plants. A major portion of this article is also devoted to understanding and deciphering the nexus between As stress-responsive mechanisms and its underlying complex interconnected regulatory networks.

Abstract
Cytotoxic chemotherapy dominates the field of cancer treatment. Consequently, anticancer phytochemicals are largely screened on the basis of their cytotoxicity towards cancer cells which are achieved at higher doses, leading to various toxic side effects. Some phytochemicals also showed pro-carcinogenic effects at certain doses. The concept of hormesis has taught us to look into biphasic responses of phytochemicals in a more systematic way. Interestingly, the monoterpenoid alcohol, linalool, also has been reported to display both anti-oxidant and pro-oxidant properties, which prompted us to explore a probable biphasic effect on cancer cells. Cytotoxicity of various concentrations of linalool (0.1-4 mM) was tested on B16F10 murine melanoma cell line, and two sub-lethal concentrations (0.4 and 0.8 mM) were selected for further experiments. 0.4 mM linalool inhibited angiogenesis and metastasis, while 0.8 mM increased them. Similarly, B16F10 cell migration, invasion, and epithelial-mesenchymal transition markers also showed inhibition and induction with lower and higher linalool concentrations, respectively. Chorioallantoic membrane assay, scratch wound assay, and Boyden's chamber were used to analyze angiogenesis and metastasis. Expression of molecular markers such as vascular endothelial growth factor (VEGF) and its receptor phosphorylated VEGF receptor II (p-VEGFRII or p-Flk-1), Hypoxia-inducible factor-1 α (HIF-1α), E-cadherin, and vimentin were detected using Western blot, ELISA, PCR, qPCR, and immunofluorescence. Finally, ChIP assay was performed to evaluate HIF-1α association with VEGF promoter. Interestingly, measurement of intracellular reactive oxygen species at the selected concentrations of linalool using DCFDA in a flow cytometer showed that the phytochemical induced significant amount of ROS at 0.8 mM. This work sheds light on bimodal dose-response relationship exhibited by dietary phytochemicals like linalool, and it should be taken into consideration to elicit a desirable therapeutic effect.

Abstract
The efficient removal of silica from rice straw and separation of its major components is essential for further valorization to produce value-added products. With regard to this, the isolation of cellulose (CEL), hemicellulose (HEM), and lignin (LIG) is imperative but quite challenging. Among several pretreatments of lignocellulosic biomass, the organosolv approach is deemed as one of the promising methods. Here, we present two different two-step approaches for the removal of silica and disintegration of significant components from rice straw, especially CEL; (i) base pretreatment, followed by organosolv treatment in the presence of organic acid, and (ii) organosolv pretreatment in the presence of organic acid, followed by base treatment. After each treatment, the recovered solid components are confirmed by various characterization techniques such as Fourier-transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, and thermogravimetric analysis. Method 2 demonstrates 82% total removal of HEM and LIG along with 90.4% of silica removal from rice straw to obtain CEL. Furthermore, the obtained crude CEL is found to be with a purity of 78%. Excellent removal of silica (90.4%) reflects that in a test study, the crude CEL obtained from method 2 gives a higher yield of butyl glucosides (59.6%) than rice straw, which affords 45.0% of butyl glucosides.

Abstract
The toxic metalloid arsenic (As), is a major pollutant of soil and water, imposing severe health concerns on human lives. It enters the food chain mainly through As-contaminated crops. The uptake, translocation and accumulation of As in plant tissue are often controlled by certain soil-inhabiting microbial communities. Among them, indigenous, free-living As-resistant plant growth-promoting rhizobacteria (PGPR) plays a pivotal role in As-immobilization. Besides, the plant's inability to withstand As after a threshold level is actively managed by these PGPR increasing As-tolerance in host plants by a synergistic plant-microbe interaction. The dual functionality of As-resistant PGPR i.e., phytostimulation and minimization of As-induced phytotoxic damages are one of the main focal points of this review article. It is known that such PGPR having the functional arsenic-resistant genes (in ars operon) including As-transporters, As-transforming genes contributed to the As accumulation and detoxification/transformation respectively. Apart from assisting in nutrient acquisition and modulating phytohormone levels, As-resistant PGPR also influences the antioxidative defense system in plants by maneuvering multiple enzymatic and non-enzymatic antioxidants. Furthermore, they are effective in reducing membrane damage and electrolyte leakage in plant cells. As-induced photosynthetic damage is also found to be salvaged by As-resistant PGPR. Briefly, the eco-physiological, biochemical and molecular mechanisms of As-resistant PGPR are thus elaborated here with regard to the As-exposed crops.

Enhanced magnetic and room temperature intrinsic magnetodielectric effect in Mn modified Ba 2Mg 2Fe 12O 22 Y-type hexaferrite. JOURNAL OF PHYSICS.

Abstract
We have reported a systematic investigation on structural, magnetic, magnetodielectric and magnetoimpedance characteristics of Y-type Ba2Mg2(Fe1-x Mn x )12O22 (0 ⩽ x ⩽ 0.12) hexaferrite synthesized by solid-state reaction route. Rietveld refinement of x-ray diffraction pattern confirms the phase purity of all the samples with rhombohedral crystal structure. The Mn dopant modulates not only superexchange angle near to the boundary of magnetic blocks but also magnetic transition temperature. Temperature-dependent magnetization data suggests that due to Mn doping at Fe sites, ferrimagnetic to proper screw transition temperature (T II) increases from 190 K to 208 K, while there is a decrease in proper screw to longitudinal conical spin transition temperature (T I) from 35 K to 25 K. We observe remarkable decrease in the magnetic field from 20 kOe to 12 kOe to produce intermediate spin ordering from ferrimagnetic ordering which can be understood because of modification of superexchange angle due to Mn doping. The value of loss tangent decreases with increasing doping concentration at 300K, i.e. ~60% and 180% in BMFM4 (x = 0.04) and BMFM8 (x = 0.08) respectively as compared to BMF, suggesting the evolution of intrinsic feature in the doped samples. Magnetodielectric (MD) effect shows that in the low-frequency regime, the robust MD effect is because of Maxwell-Wagner interfacial polarization, whereas in the high-frequency regime intrinsic effect dominates. Further, magnetoimpedance measurement confirms the presence of substantial intrinsic MD% (~6%) at 1.3 T applied field at 300 K for 4% Mn-doped sample. Finally, the nature and strength of magnetoelectric coupling in BMFM4 and BMFM8 samples at 300 K is found to be biquadratic (P 2 M 2) and maximum strength of coupling is 3.09 × 10-4 emu2 g-2 and 2.34 × 10-4 emu2 g-2, respectively.

Abstract
5-Hydroxymethylfurfural (HMF) is one of the versatile platform molecules that can be derived from biomass, and a promising starting substrate for producing 2,5-diformylfuran (DFF) and 2,5-furandicarboxylic acid (FDCA). DFF is a platform chemical with applications in pharmaceuticals, macrocyclic ligands, and functional polymeric materials. Importantly, FDCA is being considered as a potential alternative to replace terephthalic acid for producing the bioplastic polyethylene furanoate, instead of polyethylene terephthalate, by blending with ethylene glycol. A significant number of studies have focused on the oxidation of HMF to FDCA with metal-containing heterogeneous catalysts in both aqueous and organic media in the presence of peroxides/air/molecular oxygen as the oxidant. In this regard, articles have recently been published related to HMF oxidation with base (nonprecious)-metal-containing catalysts that exhibit appealing activity towards DFF or FDCA in terms of yield. Thus, this Minireview focuses on recent developments in efficient transformations of HMF to DFF and FDCA with base-metal-containing heterogeneous catalysts in aqueous and organic media. This review further focuses on the direct transformation of glucose/fructose to DFF and/or FDCA with nonprecious-metal-containing catalysts in various solvents. Photocatalytic approaches for HMF oxidation with nonprecious metal- containing catalysts are also briefly discussed.

Abstract
Dyspepsia is a symptom complex that includes epigastric pain, post-prandial fullness, bloating, early satiety, belching, nausea, vomiting, heartburn, acid regurgitations and anorexia. The most widely applied definition of dyspepsia is the Rome working team formulation namely chronic or recurrent pain or discomfort centered in the upper abdomen. Till date the prevalence of dyspepsia in Bangladesh has not been studied much. The last study was done in 1987 in a rural community and the prevalence of dyspepsia was found to be 41.4%. However, associated risk factors were not assessed and definition of dyspepsia was much narrower as well as the dysmotility type dyspepsia was not included in that study. Hence it is now high time to carry out another study to see the prevalence of dyspepsia in Bangladesh and the risk factors associated with it. To determine the prevalence of dyspepsia and the demographic risk factors associated with dyspepsia in the adult population in the rural community of Bangladesh. This cross sectional population based study carried out in Ghior Union of Manikgonj district of Bangladesh from January 2007 to April 2008. All persons 18 years or above living in Ghior Union were considered as the study populations with using a pre-designed questionnaire. This study showed that the prevalence of dyspepsia to be 61.9%. Reflux- like dyspepsia was the commonest sub-type of dyspepsia without reflux symptoms comprising 43.9% of the total population and 70.9% of the dyspeptics. Dysmotility like dyspepsia comprised more than half of the dyspeptics. Nausea (40.7%) was the most predominant dysmotility like dyspeptic symptoms followed by early satiety (38.4%); 13.9% of the population had history of recurrent upper abdominal pain and 11.9% of the population had gastro-esophageal reflux disease (GERD). There was considerable overlapping (16.7%) of IBS with dyspepsia. Female sex, younger age (<40 years), low family income (<5000 Taka per month), lower educational level (up to primary level), smoking and use of NSAIDs were significantly associated with dyspepsia. The prevalence of dyspepsia in adult population of Bangladesh is 61.9% which is very high compared to other countries and also much higher than the prevalence found in our country thirty years back. A great change in the socio-economic status and lifestyle of the people along with environmental pollution and food adulteration may be responsible for this increase in prevalence. This study was conducted in only one union of this country, so it was not representative of the whole population of the country. Therefore further study with large population size including rural and urban peoples from different parts of Bangladesh is needed to estimate the accurate prevalence of dyspepsia in our country.

Abstract
The present study evaluated the effect of parboiling on milling, chemical constituents, pasting and cooking properties of different paddy varieties. Parboiling decreased L* and a* values and increased b* and head rice recovery. Parboiling significantly increased the protein content and antioxidant activity on a dry basis. Parboiling decreased whiteness, fat content, and paste viscosities. The parboiling process increased the hydrophobicity of rice from all the varieties. Parboiled milled rice showed higher free and bound phenolic acids as compared to unparboiled milled rice. Parboiled milled rice showed higher content of essential amino acid than unparboiled milled rice. Variety PB1121 was suited best for parboiling on the basis of total color (ΔE), protein content, essential amino acid, and phenolic acids among the evaluated paddy varieties. PRACTICAL APPLICATION: The present study revealed that parboiled milled rice had higher antioxidant activity, amino acids, ferulic acid, and p-coumaric acids. Indeed, parboiled milled rice showed better textural and nutritional properties and would be more suitable for canning, puffed rice and biryani (rice cooked with chicken/mutton).

Abstract
This present study was aimed to evaluate proximate composition, antioxidant activity, amino and phenolic acids, protein profile and pasting characteristics of pigmented rice (PR) and non pigmented rice (NPR) landraces grown in Himalayan region. Higher antioxidant activity, total phenolic content, fat and protein content were observed for PR as compared to NPR. Histidine, iso-leucine, lysine, methionine, phenyl-alanine, valine and threonine were significantly higher for PR. Paste viscosities were higher for NPR (except IC568266) as compared to PR. IC568266 was observed to be waxy landrace. Higher free (gallic acid, catechin, caffeic acid, vanillic acid, sinapic acid and luteolin) and bound phenolics (ferulic acid, p-coumaric acid and quercetin) were observed in PR as compared to NPR. Majority of PR landraces showed higher accumulation of prolamines with low molecular weight polypeptides of 18, 20 and 29 kDa as compared to NPR. PR showed the higher essential amino acids, phenolic acids (p-coumaric acid, ferulic acid and quercetin) and antioxidant activity with improved nutritional value and showed potential for developing nutraceutical and functional foods.

Risk factors for diagnostic delay in Crohn's disease and their impact on long-term complications: how do they differ in a tuberculosis endemic region? Aliment Pharmacol Ther 2018; 47:1367-1374.

Abstract
BACKGROUND The diagnosis of Crohn's disease (CD) can be delayed in clinical practice. In tuberculosis endemic areas, empirical anti-tubercular therapy further delays treatment. AIM(S) To assess risk factors for diagnostic delay and its impact on the long-term complications of Crohn's disease in India where tuberculosis is endemic. METHODS Data from a large prospectively established inflammatory bowel disease registry were analysed retrospectively. The time from onset of symptoms to diagnosis (diagnostic delay) was calculated and categorised into two groups based on median diagnostic delay. The risk factors for delay including anti-tubercular therapy were analysed. Logistic regression analysis was done to assess impact of diagnostic delay on development of stenotic and fistular complications including need for surgery. RESULTS Seven hundred and twenty Crohn's disease patients (60.3% male, median: 28 years) were included. Main outcome measures were stenosis, fistula and need for surgery. Subjects with diagnostic delay >18 months (median) developed significantly higher stenotic complications and surgery (OR 4.12; 95% CI: 2.74-6.33, P < 0.001 and OR 2.41, 95% CI: 1.68-3.42, P < 0.001), respectively, compared to those ≤18 months. There was no difference in the development of fistulous complications. 193/720 (27%) received anti-tubercular therapy which significantly contributed to diagnostic delay (OR: 2.47; 95% CI: 1.76-3.47, P < 0.001) with 47% showing initial clinical response (Crohn's disease activity index- CDAI decrease >100). Moreover, the incidence of stenotic complications was significantly higher in patients who had received prior anti-tubercular therapy (55/193 (28.49%) vs 78/527 (14.8%), P < 0.001, OR: 2.60, 95% CI: 1.64-4.12). CONCLUSIONS Diagnostic delay in Crohn's disease is associated with significantly higher stenotic complications and need for surgery. Empirical anti-tubercular therapy is the single largest contributor to diagnostic delay in tuberculosis endemic areas. Despite initial clinical response to anti-tubercular therapy, long-term stenotic complications are higher.

Abstract
Sacubitril/valsartan (LCZ696) is indicated for the treatment of patients with heart failure and reduced ejection fraction (HFrEF). Since patients with HFrEF may receive sacubitril/valsartan and sildenafil, both increasing cyclic guanosine monophosphate, the present study evaluated the pharmacokinetic and pharmacodynamic drug interaction potential between sacubitril/valsartan and sildenafil. In this open‐label, three‐period, single sequence study, patients with mild‐to‐moderate hypertension (153.8 ± 8.2 mmHg mean systolic blood pressure (SBP)) received a single dose of sildenafil 50 mg, sacubitril/valsartan 400 mg once daily for 5 days, and sacubitril/valsartan and sildenafil coadministration. When coadministered with sildenafil, the AUC and Cmax of valsartan decreased by 29% and 39%, respectively. Coadministration of sacubitril/valsartan and sildenafil resulted in a greater decrease in BP (–5/–4/–4 mmHg mean ambulatory SBP/DBP/MAP (mean arterial pressure)) than with sacubitril/valsartan alone. Both treatments were generally safe and well tolerated in this study; however, the additional BP reduction suggests that sildenafil should be administered cautiously in patients receiving sacubitril/valsartan. Unique identifier: NCT01601470.

Abstract
The effects of transplantation date on milled rice (physicochemical, amino acids composition and protein profiling) of different cultivars and their starch characteristics (granules size distribution, pasting and thermal) were investigated. Head rice yield increased (2.0-4.1 %) and chalky grains (5-10 %) decreased with delaying the paddy transplantation of different cultivars by 20 days. Delayed transplantation of paddy significantly increased asparagine, glutamine, threonine, cysteine, methionine, tryptophan, lysine and proline content in milled rice. Early transplantation of paddy showed higher accumulation of glutelin and prolamines than that in milled rice from delayed transplantation. The change in amino acid composition of milled rice with delay in transplantation was related to variation in accumulation of glutelin and prolamines. Starch from delayed transplanted paddy showed higher peak viscosity and lower breakdown viscosity than those from early transplanted paddy. These differences were due to higher accumulation of amylose in starch from delayed transplanted paddy than that from early transplanted paddy due to exposure of former to lower night air temperature during starch synthesis.
