Tourism is Australia's fourth-largest exporting sector, yet little research has been done on how satisfied guests are with the indoor environmental quality (IEQ) of Australian guest homes. This research project utilized web-mining, natural language processing and sentiment analysis to analyse customers' IEQ satisfaction in Australian tourist accommodations across ten tourism cities. By analysing 543,213 guest reviews from 1,397 hotels and serviced apartments with two-stars and above at the Booking.com, guests' text comments were classified by semi-supervised word-embedding based models into nine IEQ dimensions. Using a bespoke deep sequence model, sentiment polarities were found, and sentiment scores were computed to estimate the degree of IEQ satisfaction. Results showed that guests were most dissatisfied with facilities, cleanliness and maintenance, and acoustics. As the buildings' star ratings increased, dissatisfaction towards thermal environment, indoor air quality (IAQ), and acoustics decreased. Some IEQ dimensions displayed seasonal trends in customer dissatisfaction. The main sources of dissatisfaction with the thermal environment, IAQ, lighting, and acoustics were identified.

The pressurized heavy water reactors which are used for power production make use of heavy water in moderator and in primary heat transport system. The cationic fission products produced during the reactor operation such as cesium, strontium, cobalt, palladium, ruthenium and anions iodide, iodate, ruthenate, etc. contaminate the heavy water and hence the need for purification of the moderator and primary heat transport system to nuclear grade to achieve the desired efficiency arises. Columns containing ion exchange resins in online are used for purification. Also ion exchange resins are used in purification of fuel storage pond water. In this purification process, the resins pick up activity and ionic impurities. The activity-loaded resin so formed is called spent resin. It is imperative to treat the spent resin into innocuous form, highly inert towards exchange with any external radioactivity. Hence, an attempt has been made to convert the Cs-containing spent resin into ferric form and to study the role of temperature in the exchange reactions. Results show that the spent resin of Cs form could be completely converted into ferric form in batch study. Also the extent of exchange to ferric form was found to come down with temperature resulting in the release of -59.46 KJ/mole with cesium form of resin. [ABSTRACT FROM AUTHOR]

Machine learning techniques were applied with statistical tools such as linear, logistic and multinomial regression, to work out predictive algorithms for yield estimation. Spectroradiometer readings were collected throughout the main maiz producing provinces of Ecuador, at two crop development stages. A model using six degree polynomial regression is recommended for acceptable yield prediction. This model could contribute to decide about imports strategies and avoid the overlapping with the national production.

Pyridoxal 5'-phosphate (PLP)-dependent enzymes are the most versatile biocatalysts for synthesizing nonproteinogenic amino acids. α,α-Disubstituted quaternary amino acids, such as 1-aminocyclopentane-1-carboxylic acid (cycloleucine), are useful building blocks for pharmaceuticals. In this study, starting with the biosynthesis of fusarilin A, we discovered a family of PLP-dependent enzymes that can facilitate tandem carbon-carbon forming steps to catalyze an overall [3 + 2]-annulation. In the first step, the cycloleucine synthases use SAM as the latent electrophile and an in situ-generated enamine as the nucleophile for γ-substitution. Whereas previously characterized γ-replacement enzymes protonate the resulting α-carbon and release the acyclic amino acid, cycloleucine synthases can catalyze an additional, intramolecular aldol or Mannich reaction with the nucleophilic α-carbon to form the substituted cyclopentane. Overall, the net [3 + 2]-annulation reaction can lead to 2-hydroxy or 2-aminocycloleucine products. These studies further expand the biocatalytic scope of PLP-dependent enzymes.

G-protein coupled receptors (GPCRs) are the most prominent family of membrane proteins that serve as major targets for one-third of the drugs produced. A detailed understanding of the molecular mechanism of drug-induced activation and inhibition of GPCRs is crucial for the rational design of novel therapeutics. The binding of the neurotransmitter adrenaline to the β 2 -adrenergic receptor (β 2 AR) is known to induce a flight or fight cellular response, but much remains to be understood about binding-induced dynamical changes in β 2 AR and adrenaline. In this article, we examine the potential of mean force (PMF) for the unbinding of adrenaline from the orthosteric binding site of β 2 AR and the associated dynamics using umbrella sampling and molecular dynamics (MD) simulations. The calculated PMF reveals a global energy minimum, which corresponds to the crystal structure of β 2 AR-adrenaline complex, and a meta-stable state in which the adrenaline is moved slightly deeper into the binding pocket with a different orientation compared to that in the crystal structure. The orientational and conformational changes in adrenaline during the transition between these two states and the underlying driving forces of this transition are also explored. Based on the clustering of MD configurations and machine learning-based statistical analyses of time series of relevant collective variables, the structures and stabilizing interactions of these two states of the β 2 AR-adrenaline complex are also investigated.

Isonitrile lipopeptides (INLPs) are known to be related to the virulence of pathogenic mycobacteria by mediating metal transport, but their biosynthesis remains obscure. In this work, we use in vitro biochemical assays, site-directed mutagenesis, chemical synthesis, and spectroscopy techniques to scrutinize the activity of core enzymes required for INLP biosynthesis in mycobacteria. Compared to environmental Streptomyces , pathogenic Mycobacterium employ a similar chemical logic and enzymatic machinery in INLP biosynthesis, differing mainly in the fatty-acyl chain length, which is controlled by multiple enzymes in the pathway. Our in-depth study on the non-heme iron(II) and α-ketoglutarate-dependent dioxygenase for isonitrile generation, including Rv0097 from Mycobacterium tuberculosis ( Mtb ), demonstrates that it recognizes a free-standing small molecule substrate, different from the recent hypothesis that a carrier protein is required for Rv0097 in Mtb . A key residue in Rv0097 is further identified to dictate the varied fatty-acyl chain length specificity between Streptomyces and Mycobacterium .

Background: The available evidence was systematically reviewed to evaluate the effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors (SGLT2i) on cardiovascular (CV) and renal outcomes in people with type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular disease (ASCVD) or multiple risk factors (MRF), with or without heart failure (HF), and per estimated glomerular filtration rate (eGFR) rate at baseline., Methods: We comprehensively searched three electronic databases to retrieve publications up to 30th November 2019, which were screened for inclusion. The data extracted for the outcomes according to baseline ASCVD, HF, and eGFR levels were meta-analyzed using fixed effects model., Results: Of the 735 screened citations, 15 primary and secondary publications from five CV or renal outcome trials were included. SGLT2is reduced the risk of CV death or hospitalization for HF (HHF), HHF alone, and composite renal-specific outcome, irrespective of ASCVD and HF at baseline. The three-point major adverse cardiovascular events (3P-MACE) risk was reduced by 14% (p<0.001) in patients with ASCVD and by 10% (p = 0.018) in those without baseline HF compared with their counterparts. SGLT2is significantly reduced the risk of MACE (18%) in patients with mild kidney dysfunction (eGFR within the range of 60-<90 mL/min/1.73 m2 and <60 mL/min/1.73 m2 )., Conclusion: SGLT2is are effective for both secondary and primary prevention of composite CV outcomes, and secondary prevention of MACE. The upcoming evidence may strengthen the primary prevention benefits of SGLT2is., (© Journal of the Association of Physicians of India 2011.)

Parental care is widespread and has fitness benefits. But caregiving parents incur costs including higher predation, and this may lead to selection for body colors or patterns that help mitigate the risks of caring. The evolution of coloration, including sexual dichromatism, however, can be driven by other factors, such as sexual selection. Therefore, examining the associations between parental care and color patterns may provide key insights into evolutionary patterns and selection pressures for parental care. Our comparative analysis of 988 anuran species reveals that dichromatic species are less likely to provide parental care, irrespective of the caregiving sex, and are more likely to breed in aquatic habitats. We then examined whether dorsal colors and patterns that enhance crypticity or function as aposematic signals are associated with the caregiving sex, and the modality of care (transport or stationary). Only caregiving males are more likely to have dorsal Stripes, but none of the colors (Green-Brown, Red, Yellow, Blue-Black) and other patterns (Plain, Bands, Spots, Mottled-Patches) were associated with caregiving females or the modality of care. Overall, sexual dichromatism, breeding ecology, and parental care are associated, but the evolution of caregiving behavior does not appear to influence the myriad colors and patterns characteristic of anurans globally., (© 2022 The Authors.

Background Type 2 diabetes mellitus (T2DM) is associated with a significant burden on both patients and the healthcare system. This study aimed to evaluate the demographics of patients with T2DM receiving different strengths of glimepiride and metformin combination along with insulin. This study also examined the concomitant conditions and therapies, duration of therapies, dosage titration, glycated hemoglobin (HbA1c) levels, hypoglycemic events, and weight changes during the course of therapy. Methods This retrospective, multicenter (347), observational study included adult patients with T2DM who received glimepiride and metformin combination along with insulin. Data related to demographic characteristics, duration of disease, co-morbidities, concomitant medications, and dosage pattern was collected from medical records authenticated by physicians during routine care. Results A total of 7058 patients were included in the study. The median age of included patients was 55 years and around 29% were aged >60 years and 60% were men. The majority of patients (83.3%) had insulin treatment initiation after glimepiride and metformin combination while other patients (16.7%) received glimepiride and metformin combination after insulin initiation. The mean HbA1c levels significantly decreased with a mean change of 1.33%. In one-third of the patients, down-titration of the insulin dose was done, indicating the insulin-sparing effect with the addition of the glimepiride and metformin combination. The most common comorbid condition was hypertension (64.7%). Of 3705 patients, 33.2% patients had weight loss and 66.8% had weight gain. A total of 432 patients reported hypoglycemic events. Physician global evaluation of efficacy and tolerability showed a good to excellent on the scale (97.3% and 96.6%). Conclusion This study presented good HbA1c lowering with glimepiride and metformin combination with insulin, ensuring a positive clinical outcome. Good to excellent efficacy and tolerability were observed in patients with T2DM across the age groups, in early as well as long-standing disease., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2021, Prasanna Kumar et al.)

Classroom response systems are an important tool in many active learning pedagogies. They support real-time feedback on student learning and promote student engagement, even in large classrooms, by allowing instructors to solicit an answer to a question from all students and show the results. Existing classroom response systems are general purpose and not tailored to the specific needs of a chemistry classroom. In particular, it is not easy to deploy molecular representations except as static images. Here we present the 3Dmol.js learning environment, a classroom response system that uses the open source web-based 3Dmol.js JavaScript framework to provide interactive viewing and querying of 3D molecules. 3Dmol.js is available under a BSD 3-clause open source license, and the learning environment features are all available through http://3dmol.csb.pitt.edu/ without any software installation required.

Aim: To develop an evidence-based expert group consensus document on the best practices and simple tools for titrating basal insulins in persons with type 2 diabetes mellitus (T2DM)., Background: Glycemic control is suboptimal in a large proportion of persons with T2DM, despite insulin therapy, thereby increasing the risk of potentially severe complications. Early initiation of insulin therapy and appropriate dose titration are crucial to achieving glycemic targets. Attitudes and practices among healthcare professionals (HCPs) and perceptions about insulin therapy among persons with diabetes contribute largely to suboptimal glycemic control. Improving HCP-patient communication, encouraging the use of additional educational tools, and providing support for the titration process to increase confidence, both at the initiation visit and at home, facilitate the optimization of dose titration. In Indian settings, specific guidelines and a consensus statement are lacking on the optimal insulin initiation dose, frequency of dose titration, and basal insulin profile needed to achieve optimal titration. In clinical practice, physicians and persons with diabetes often do not adhere to the titration algorithms that currently exist for the purpose of achieving optimal titration as they perceive these to be very cumbersome. In this context, a group of experts met at an advisory board meeting and arrived at a consensus on best practices for the titration of basal insulin in persons withT2DM in India, using the modified Delphi methodology., Review Results: After a review of evidence and further discussions, the expert group provided recommendations on insulin initiation dose, ideal period for titration in practice, titration regimen for use in practice, basal insulin profile for titration, and choosing a self-monitoring blood glucose schedule for titration., Conclusions: In the management of T2DM, insulin can be effectively titrated by following a few simple recommendations. The use of second-generation basal insulin aids in mitigating the risk of hypoglycemic events. The implementation of a simplified titration regimen is crucial to achieving glycemic targets and long-term treatment goals.

Diabetes is a major public health emergency of the 21st century. Results of the Indian Council of Medical Research-INdia DIABetes (ICMR-INDIAB) study have found prevalence of diabetes and prediabetes in India to be as high as 7.3% and 10.3%, respectively with nation-wide projection of 77.2 million people with prediabetes and 69.2 million with diabetes. It is well established that insulin resistance (IR) and islet β-cell failure are the two major features of T2D Multiple mechanisms including glucotoxicity, lipotoxicity, oxidative stress, endoplasmic reticulum stress, formation of amyloid deposits in the islets, etc. have been hypothesized to participate in the pathology of the disease. In the concluding decade of the last century, numerous studies - prospective and cross-sectional, have confirmed the role of chronic low-grade inflammation as a pathogenetic factor of T2D. It has been shown that increased levels of various inflammatory markers and mediators including fundamental markers like white blood cell count, C-reactive protein (CRP) to the more specific circulating cytokines like, interleukin-6 (IL-6), IL-1β, plasminogen activator inhibitor-1 (PAI-1), etc. correlate with incident T2D. Based on the robust evidence implying the role of inflammation in T2D pathogenesis, several studies have proven that the proinflammatory cytokines play a central role in the development of microvascular diabetic complications such as nephropathy, retinopathy, and neuropathy. Inflammation in T2D causes accelerated atherosclerosis which predisposes to CVD, the leading cause of mortality in these patients. Recently there is a considerable increase in the interest among the researchers about anti-inflammatory therapies in the setting of chronic disorders such as T2D and CV diseases. In a multi-country study conducted in Asia, approximately 50% of Indian respondents had poor diabetes control. Most patients initially respond to sulfonylurea and/or metformin, and later these agents lose their effectiveness with time. Therapeutic option in patients uncontrolled on two-drug combination therapy is either to add third oral drug or insulin. However, use of insulin is limited due to its high cost and poor compliance. Majority of new treatment options like GLP1 agonists, insulin analogs and SGLT2 inhibitors are costly considering they are still under patent. The thiazolidinedione class of drugs is associated with adverse effects like fluid retention and weight gain that may result in or exacerbate edema and congestive heart failure. Thus there is a need for a safe and inexpensive treatment option for the management of uncontrolled T2D. Considering the role of inflammation in T2D pathogenesis, the drug should not only have antihyperglycemic effects but also reduce inflammatory burden thus reducing the progression and complications of T2D. The current interest is apparently directed towards drugs targeting inflammation acting at different stages of the inflammatory cascade. In the recently published CANTOS study, canakinumab, a selective, high-affinity, fully human monoclonal antibody which inhibits IL-1β, has no consistent long-term benefits on HbA1c. Other selective inhibitors like anakinra (IL-1 receptor antagonist) and etanercept (TNF inhibitor) too have yielded modest effects on glycemic parameters and insulin sensitivity. However, hydroxychloroquine (HCQ), a broad anti-inflammatory agent has been shown to reduce HbA1c by 0.87%. Hydroxychloroquine (HCQ) is considered as one of the safest disease modifying anti-rheumatic drug, used widely for the treatment of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The effect of HCQ in preventing development of diabetes in patients with chronic inflammatory diseases was highlighted in a prospective observational study of 4905 adults with rheumatoid arthritis and no diabetes with 21.5 years of follow-up. Patients who took HCQ for more than 4 years had a significant 77% lower risk of diabetes compared with non users of HCQ (RR, 0.23; 95% CI, 0.11-0.50). Taking cue from this study highlighting the anti-diabetic effect of HCQ, pioneering research studies evaluating these effects of HCQ were conducted in India. In 2014, hydroxychloroquine 400 mg got DCGI approval as an adjunct to diet and exercise to improve glycemic control of patients on metformin, sulfonylurea combination in Type 2 diabetes., (© Journal of the Association of Physicians of India 2011.)

Glucose monitoring is an important aspect of diabetes care. The traditional methodologies of blood glucose monitoring such as fasting plasma glucose, post prandial glucose, glycosylated hemoglobin and self-monitoring of blood glucose do not adequately address hypoglycemia and glycemic variability, which are two important risk factors for diabetes-related complications. Ambulatory glucose profile (AGP) developed from a continuous glucose monitoring system is a simplified report, with standardized statistics and targets and visual representation of time in standardized glycemic ranges, glucose variability, and glycemic exposure over a single 24-h day. The role of AGP in T2DM patients who are on oral anti-diabetic drugs (OADs) is still not clearly defined. An expert group of endocrinologists and diabetologists met in Pune, India to discuss the role of AGP in T2DM patients on OADs. This article aims to discuss the consensus of the expert group on the role of AGP in T2DM patients on OADs and also reviews the various aspects of AGP and its interpretation; and the available evidences for disease management including treatment options based on AGP report., (© Journal of the Association of Physicians of India 2011.)

Purpose of Review: To review the evolution of family support movement for schizophrenia in India and to report perspectives of family caregivers who are running family support groups across the country in the backdrop of recent legislations in India., Recent Findings: Family support movement started in the 1990s, mostly by family caregivers independently in multiple cities across the country. Apart from periodic support meetings, they have successfully influenced recent legislations to address the felt needs of families. Mental health professionals need to gain skills to work collaboratively with assertive family caregivers to develop services to support those diagnosed with mental illness. Though there is a need for such movement, funding is poor and very few caregivers of persons with schizophrenia are forthcoming to participate. The formation of national federation with government and non-government partnership could help give the required impetus to the family support movement for persons with schizophrenia in India.

Personalized medicine is an individualized and stratified approach to the management of a disease. Personalized medicine can reform the prevention, prediction, and management of diabetes. Use of genetic information in polygenic and monogenic forms of diabetes can help to identify genetic variants and reclassify patients into pathophysiological subgroups. Targeted diagnostic, preventive, and therapeutic interventions can be defined for these groups for effective management of diabetes. Pharmacogenetics combines genotypic and phenotypic factors to develop personalized care in various pathophysiological subgroups of persons with diabetes. Personalized medicine finds wider utility in monogenic (especially Maturity Onset Diabetes of the Young (MODY) and Neonatal Diabetes Mellitus [NDM]) than in polygenic, diabetes. The most frequently mutated genes in MODY include HNF1A and HNF3A. the common genes responsible for NDM include KCNJ11 and ABCC8 (SUR) genes. These genes influence various aspects of glucose metabolism such as β-cell K-ATP channel modulation, production of insulin and development of pancreas. The Madras Diabetes Research Foundation has fostered research in personalized medicine for diabetes based upon genetic information and has developed a national registry for neonatal diabetes and other monogenic form of diabetes., (© Journal of the Association of Physicians of India 2011.)

Over the time due to progressive nature of diabetes, proactive intensification of the existing insulin therapy becomes imminent as it minimizes patients' exposure to chronic hypo/hyperglycaemia and reduces weight gain while achieving individualized glycaemic targets. This review focuses on the strength of evidence behind various options for intensification, primarily the insulins as also the GLP-1 analogues. The recommendations presented here are meant to serve as a guide for the physician managing type 2 diabetes patients requiring insulin intensification upon failing of basal insulin therapy., (Copyright © 2017 Diabetes India.

Religious practices and cultural customs related to eating habits have a significant impact on lifestyle and health of the community. The Ramadan fasting in Muslims and its influence on various metabolic parameters such as diabetes have been reasonably studied. However, literature related to Hindu religious customs related to fasting and food patterns during various festivals and its effect on diabetes are scarce. This article is an attempt to describe the Hindu religious customs related to fasting and food practices from the State of Tamil Nadu (South India) and to raise the awareness among physicians about its relationship with diabetes which may help in managing their diabetic patients in a better way.

We propose a facial alignment algorithm that is able to jointly deal with the presence of facial pose variation, partial occlusion of the face, and varying illumination and expressions. Our approach proceeds from sparse to dense landmarking steps using a set of specific models trained to best account for the shape and texture variation manifested by facial landmarks and facial shapes across pose and various expressions. We also propose the use of a novel l1-regularized least squares approach that we incorporate into our shape model, which is an improvement over the shape model used by several prior Active Shape Model (ASM) based facial landmark localization algorithms. Our approach is compared against several state-of-the-art methods on many challenging test datasets and exhibits a higher fitting accuracy on all of them.

Objective: The primary objective of this study is to estimate the prevalence of chronic kidney disease (CKD) among type 2 diabetes mellitus (T2DM) patients in India., Materials and Methods: This cross-sectional, observational, epidemiological, multi-center, study is enrolling T2DM patients of either gender aged 30 years or above. This study aimed to enroll a total of 3000 T2DM patients at 30 participating hospitals/clinics across India and the data from a planned interim analysis of 1500 patients are presented here. The primary endpoint of the study is to estimate proportion of T2DM patients with CKD (glomerular filtration rate [GFR] <60 ml/min/1.73 m(2) or albumin creatinine ratio [ACR] ≥30 mg/g or ≥3 mg/mmol or both). Routine treatment, as administered by the treating physician, was continued without any study specific intervention. Patients' data pertaining to demographic characteristics, medical history, current medication and physical examination were recorded. The blood/plasma and urine samples, were collected for estimation of hemoglobin A1c, microalbuminuria, serum creatinine, urine creatinine, and routine urine analysis. ACR was calculated from urine creatinine and albumin while GFR was estimated by using a modification of diet in the renal disease equation., Results: Study recruited 1500 patients from 18 centers across India. The study population included 840 (56.05%) males. Mean age, body mass index and systolic blood pressure were 55.1 years, 27.4 kg/m(2) and 134.5 mmHg respectively. The mean duration of diabetes was 102.2 months. History of co-morbid diseases such as dyslipidemia, hypertension, microvascular complications and macrovascular complications was present in 657 (43.8%), 655 (43.7%), 268 (17.9%) and 104 (6.93%), respectively. This interim analysis revealed that about 46% of the T2DM patients had CKD (urinary albumin creatinine ratio (UACR) ≥30 mg/g and/or estimated GFR [eGFR] <60 mL/min/1.73 m(2)). The renal dysfunction as per eGFR criteria (<60 mL/min/1.73 m(2)) was reported in about 23% while as per UACR criteria (≥30 mg/g) it was reported in about 35% patients., Conclusion: This interim analysis results suggests that over 40% of T2DM patients have CKD. Despite this high number of T2DM patients with CKD, eGFR analysis shows there are almost 80% of T2DM patients still have reasonably good renal function (eGFR above 60 ml/min), which ensures less restrictions in selecting oral anti-diabetic drugs. Full study results from Start-India study will provide detail insights into the occurrence of CKD in patients with T2DM in India.

A highly stereoselective construction of 2,6-cis-disubstituted tetrahydropyrans was achieved by using an intramolecular amide enolate alkylation with KHMDS. The efficiency and practicality of this methodology was successfully demonstrated in the total synthesis of (-)-centrolobine (1).
