IN VITRO ANTHELMINTIC ACTIVITY OF ABUTILON THEOPHRASTI MEDIK. (MALVACEAE) AGAINST EGGS AND L3 LARVAE OF HAEMONCHUS CONTORTUS

Objective: The present study was carried out to assess the in vitro anthelmintic activity of Abutilon theophrasti stem extracts. Methods: Simple maceration was employed for extraction. Solvents such as methanol, water, and hexane were used. Egg hatch test (EHT) and larval motility test were employed to check the anthelmintic activity of crude extracts. Concentrations of 500, 250, 125, 62.5, and 31.25 mg/ml were made. Levamisole and distilled water served as control, respectively. Results: All selected extracts displayed concentration-dependent inhibition except aqueous extracts. At higher concentration (500 mg/ml), stem extracts (methanol, aqueous, and ethanol) showed 74.39%, 72.5 and 70.03% of efficacy in EHT, respectively (p≤0.05). Meanwhile, inhibition of larval motility was seen higher with inhibition percentage of 79.79, 75.65, and 71.28 by methanolic, aqueous, and hexane extracts, respectively (p≤ 0.05). Conclusion: The presents study suggests active principles having anthelmintic efficacy in Abutilon theopharsti stem

EPHA2 Is Associated with Age-Related Cortical Cataract in Mice and Humans

Age-related cataract is a major cause of blindness worldwide, and cortical cataract is the second most prevalent type of age-related cataract. Although a significant fraction of age-related cataract is heritable, the genetic basis remains to be elucidated. We report that homozygous deletion of Epha2 in two independent strains of mice developed progressive cortical cataract. Retroillumination revealed development of cortical vacuoles at one month of age; visible cataract appeared around three months, which progressed to mature cataract by six months. EPHA2 protein expression in the lens is spatially and temporally regulated. It is low in anterior epithelial cells, upregulated as the cells enter differentiation at the equator, strongly expressed in the cortical fiber cells, but absent in the nuclei. Deletion of Epha2 caused a significant increase in the expression of HSP25 (murine homologue of human HSP27) before the onset of cataract. The overexpressed HSP25 was in an underphosphorylated form, indicating excessive cellular stress and protein misfolding. The orthologous human EPHA2 gene on chromosome 1p36 was tested in three independent worldwide Caucasian populations for allelic association with cortical cataract. Common variants in EPHA2 were found that showed significant association with cortical cataract, and rs6678616 was the most significant in meta-analyses. In addition, we sequenced exons of EPHA2 in linked families and identified a new missense mutation, Arg721Gln, in the protein kinase domain that significantly alters EPHA2 functions in cellular and biochemical assays. Thus, converging evidence from humans and mice suggests that EPHA2 is important in maintaining lens clarity with age

Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980-2017 : a systematic analysis for the Global Burden of Disease Study 2017

Background Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use of newly available data and improved methods. GBD 2017 provides a comprehensive assessment of cause-specific mortality for 282 causes in 195 countries and territories from 1980 to 2017. Methods The causes of death database is composed of vital registration (VR), verbal autopsy (VA), registry, survey, police, and surveillance data. GBD 2017 added ten VA studies, 127 country-years of VR data, 502 cancer-registry country-years, and an additional surveillance country-year. Expansions of the GBD cause of death hierarchy resulted in 18 additional causes estimated for GBD 2017. Newly available data led to subnational estimates for five additional countries Ethiopia, Iran, New Zealand, Norway, and Russia. Deaths assigned International Classification of Diseases (ICD) codes for non-specific, implausible, or intermediate causes of death were reassigned to underlying causes by redistribution algorithms that were incorporated into uncertainty estimation. We used statistical modelling tools developed for GBD, including the Cause of Death Ensemble model (CODErn), to generate cause fractions and cause specific death rates for each location, year, age, and sex. Instead of using UN estimates as in previous versions, GBD 2017 independently estimated population size and fertility rate for all locations. Years of life lost (YLLs) were then calculated as the sum of each death multiplied by the standard life expectancy at each age. All rates reported here are age-standardised. Findings At the broadest grouping of causes of death (Level 1), non-communicable diseases (NC Ds) comprised the greatest fraction of deaths, contributing to 73.4% (95% uncertainty interval [UI] 72.5-74.1) of total deaths in 2017, while communicable, maternal, neonatal, and nutritional (CMNN) causes accounted for 186% (17.9-19.6), and injuries 8.0% (7.7-8.2). Total numbers of deaths from NCD causes increased from 2007 to 2017 by 22.7% (21.5-23.9), representing an additional 7.61 million (7. 20-8.01) deaths estimated in 2017 versus 2007. The death rate from NCDs decreased globally by 7.9% (7.08.8). The number of deaths for CMNN causes decreased by 222% (20.0-24.0) and the death rate by 31.8% (30.1-33.3). Total deaths from injuries increased by 2.3% (0-5-4-0) between 2007 and 2017, and the death rate from injuries decreased by 13.7% (12.2-15.1) to 57.9 deaths (55.9-59.2) per 100 000 in 2017. Deaths from substance use disorders also increased, rising from 284 000 deaths (268 000-289 000) globally in 2007 to 352 000 (334 000-363 000) in 2017. Between 2007 and 2017, total deaths from conflict and terrorism increased by 118.0% (88.8-148.6). A greater reduction in total deaths and death rates was observed for some CMNN causes among children younger than 5 years than for older adults, such as a 36.4% (32.2-40.6) reduction in deaths from lower respiratory infections for children younger than 5 years compared with a 33.6% (31.2-36.1) increase in adults older than 70 years. Globally, the number of deaths was greater for men than for women at most ages in 2017, except at ages older than 85 years. Trends in global YLLs reflect an epidemiological transition, with decreases in total YLLs from enteric infections, respirator}, infections and tuberculosis, and maternal and neonatal disorders between 1990 and 2017; these were generally greater in magnitude at the lowest levels of the Socio-demographic Index (SDI). At the same time, there were large increases in YLLs from neoplasms and cardiovascular diseases. YLL rates decreased across the five leading Level 2 causes in all SDI quintiles. The leading causes of YLLs in 1990 neonatal disorders, lower respiratory infections, and diarrhoeal diseases were ranked second, fourth, and fifth, in 2017. Meanwhile, estimated YLLs increased for ischaemic heart disease (ranked first in 2017) and stroke (ranked third), even though YLL rates decreased. Population growth contributed to increased total deaths across the 20 leading Level 2 causes of mortality between 2007 and 2017. Decreases in the cause-specific mortality rate reduced the effect of population growth for all but three causes: substance use disorders, neurological disorders, and skin and subcutaneous diseases. Interpretation Improvements in global health have been unevenly distributed among populations. Deaths due to injuries, substance use disorders, armed conflict and terrorism, neoplasms, and cardiovascular disease are expanding threats to global health. For causes of death such as lower respiratory and enteric infections, more rapid progress occurred for children than for the oldest adults, and there is continuing disparity in mortality rates by sex across age groups. Reductions in the death rate of some common diseases are themselves slowing or have ceased, primarily for NCDs, and the death rate for selected causes has increased in the past decade.

Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories: a systematic analysis for the Global Burden of Disease Study 2017

Background: Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030. To fully deliver on the SDG aim of “leaving no one behind”, it is increasingly important to examine the health-related SDGs beyond national-level estimates. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017), we measured progress on 41 of 52 health-related SDG indicators and estimated the health-related SDG index for 195 countries and territories for the period 1990–2017, projected indicators to 2030, and analysed global attainment. Methods: We measured progress on 41 health-related SDG indicators from 1990 to 2017, an increase of four indicators since GBD 2016 (new indicators were health worker density, sexual violence by non-intimate partners, population census status, and prevalence of physical and sexual violence [reported separately]). We also improved the measurement of several previously reported indicators. We constructed national-level estimates and, for a subset of health-related SDGs, examined indicator-level differences by sex and Socio-demographic Index (SDI) quintile. We also did subnational assessments of performance for selected countries. To construct the health-related SDG index, we transformed the value for each indicator on a scale of 0–100, with 0 as the 2\ub75th percentile and 100 as the 97\ub75th percentile of 1000 draws calculated from 1990 to 2030, and took the geometric mean of the scaled indicators by target. To generate projections through 2030, we used a forecasting framework that drew estimates from the broader GBD study and used weighted averages of indicator-specific and country-specific annualised rates of change from 1990 to 2017 to inform future estimates. We assessed attainment of indicators with defined targets in two ways: first, using mean values projected for 2030, and then using the probability of attainment in 2030 calculated from 1000 draws. We also did a global attainment analysis of the feasibility of attaining SDG targets on the basis of past trends. Using 2015 global averages of indicators with defined SDG targets, we calculated the global annualised rates of change required from 2015 to 2030 to meet these targets, and then identified in what percentiles the required global annualised rates of change fell in the distribution of country-level rates of change from 1990 to 2015. We took the mean of these global percentile values across indicators and applied the past rate of change at this mean global percentile to all health-related SDG indicators, irrespective of target definition, to estimate the equivalent 2030 global average value and percentage change from 2015 to 2030 for each indicator. Findings: The global median health-related SDG index in 2017 was 59\ub74 (IQR 35\ub74–67\ub73), ranging from a low of 11\ub76 (95% uncertainty interval 9\ub76–14\ub70) to a high of 84\ub79 (83\ub71–86\ub77). SDG index values in countries assessed at the subnational level varied substantially, particularly in China and India, although scores in Japan and the UK were more homogeneous. Indicators also varied by SDI quintile and sex, with males having worse outcomes than females for non-communicable disease (NCD) mortality, alcohol use, and smoking, among others. Most countries were projected to have a higher health-related SDG index in 2030 than in 2017, while country-level probabilities of attainment by 2030 varied widely by indicator. Under-5 mortality, neonatal mortality, maternal mortality ratio, and malaria indicators had the most countries with at least 95% probability of target attainment. Other indicators, including NCD mortality and suicide mortality, had no countries projected to meet corresponding SDG targets on the basis of projected mean values for 2030 but showed some probability of attainment by 2030. For some indicators, including child malnutrition, several infectious diseases, and most violence measures, the annualised rates of change required to meet SDG targets far exceeded the pace of progress achieved by any country in the recent past. We found that applying the mean global annualised rate of change to indicators without defined targets would equate to about 19% and 22% reductions in global smoking and alcohol consumption, respectively; a 47% decline in adolescent birth rates; and a more than 85% increase in health worker density per 1000 population by 2030. Interpretation: The GBD study offers a unique, robust platform for monitoring the health-related SDGs across demographic and geographic dimensions. Our findings underscore the importance of increased collection and analysis of disaggregated data and highlight where more deliberate design or targeting of interventions could accelerate progress in attaining the SDGs. Current projections show that many health-related SDG indicators, NCDs, NCD-related risks, and violence-related indicators will require a concerted shift away from what might have driven past gains—curative interventions in the case of NCDs—towards multisectoral, prevention-oriented policy action and investments to achieve SDG aims. Notably, several targets, if they are to be met by 2030, demand a pace of progress that no country has achieved in the recent past. The future is fundamentally uncertain, and no model can fully predict what breakthroughs or events might alter the course of the SDGs. What is clear is that our actions—or inaction—today will ultimately dictate how close the world, collectively, can get to leaving no one behind by 2030

Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories: a systematic analysis for the Global Burden of Disease Study 2017.

BACKGROUND: Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030.

Global, regional, and national incidence, prevalence, and years lived with disability for 354 diseases and injuries for 195 countries and territories, 1990–2017: A systematic analysis for the Global Burden of Disease Study 2017

Background: The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) includes a comprehensive assessment of incidence, prevalence, and years lived with disability (YLDs) for 354 causes in 195 countries and territories from 1990 to 2017. Previous GBD studies have shown how the decline of mortality rates from 1990 to 2016 has led to an increase in life expectancy, an ageing global population, and an expansion of the non-fatal burden of disease and injury. These studies have also shown how a substantial portion of the world's population experiences non-fatal health loss with considerable heterogeneity among different causes, locations, ages, and sexes. Ongoing objectives of the GBD study include increasing the level of estimation detail, improving analytical strategies, and increasing the amount of high-quality data. Methods: We estimated incidence and prevalence for 354 diseases and injuries and 3484 sequelae. We used an updated and extensive body of literature studies, survey data, surveillance data, inpatient admission records, outpatient visit records, and health insurance claims, and additionally used results from cause of death models to inform estimates using a total of 68 781 data sources. Newly available clinical data from India, Iran, Japan, Jordan, Nepal, China, Brazil, Norway, and Italy were incorporated, as well as updated claims data from the USA and new claims data from Taiwan (province of China) and Singapore. We used DisMod-MR 2.1, a Bayesian meta-regression tool, as the main method of estimation, ensuring consistency between rates of incidence, prevalence, remission, and cause of death for each condition. YLDs were estimated as the product of a prevalence estimate and a disability weight for health states of each mutually exclusive sequela, adjusted for comorbidity. We updated the Socio-demographic Index (SDI), a summary development indicator of income per capita, years of schooling, and total fertility rate. Additionally, we calculated differences between male and female YLDs to identify divergent trends across sexes. GBD 2017 complies with the Guidelines for Accurate and Transparent Health Estimates Reporting. Findings: Globally, for females, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and haemoglobinopathies and haemolytic anaemias in both 1990 and 2017. For males, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and tuberculosis including latent tuberculosis infection in both 1990 and 2017. In terms of YLDs, low back pain, headache disorders, and dietary iron deficiency were the leading Level 3 causes of YLD counts in 1990, whereas low back pain, headache disorders, and depressive disorders were the leading causes in 2017 for both sexes combined. All-cause age-standardised YLD rates decreased by 3·9% (95% uncertainty interval [UI] 3·1-4·6) from 1990 to 2017; however, the all-age YLD rate increased by 7·2% (6·0-8·4) while the total sum of global YLDs increased from 562 million (421-723) to 853 million (642-1100). The increases for males and females were similar, with increases in all-age YLD rates of 7·9% (6·6-9·2) for males and 6·5% (5·4-7·7) for females. We found significant differences between males and females in terms of age-standardised prevalence estimates for multiple causes. The causes with the greatest relative differences between sexes in 2017 included substance use disorders (3018 cases [95% UI 2782-3252] per 100 000 in males vs 1400 [1279-1524] per 100 000 in females), transport injuries (3322 [3082-3583] vs 2336 [2154-2535]), and self-harm and interpersonal violence (3265 [2943-3630] vs 5643 [5057-6302]). Interpretation: Global all-cause age-standardised YLD rates have improved only slightly over a period spanning nearly three decades. However, the magnitude of the non-fatal disease burden has expanded globally, with increasing numbers of people who have a wide spectrum of conditions. A subset of conditions has remained globally pervasive since 1990, whereas other conditions have displayed more dynamic trends, with different ages, sexes, and geographies across the globe experiencing varying burdens and trends of health loss. This study emphasises how global improvements in premature mortality for select conditions have led to older populations with complex and potentially expensive diseases, yet also highlights global achievements in certain domains of disease and injury

Global, regional, and national age-sex-specific mortality and life expectancy, 1950-2017: a systematic analysis for the Global Burden of Disease Study 2017

Background: Assessments of age-specific mortality and life expectancy have been done by the UN Population Division, Department of Economics and Social Affairs (UNPOP), the United States Census Bureau, WHO, and as part of previous iterations of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). Previous iterations of the GBD used population estimates from UNPOP, which were not derived in a way that was internally consistent with the estimates of the numbers of deaths in the GBD. The present iteration of the GBD, GBD 2017, improves on previous assessments and provides timely estimates of the mortality experience of populations globally. Methods: The GBD uses all available data to produce estimates of mortality rates between 1950 and 2017 for 23 age groups, both sexes, and 918 locations, including 195 countries and territories and subnational locations for 16 countries. Data used include vital registration systems, sample registration systems, household surveys (complete birth histories, summary birth histories, sibling histories), censuses (summary birth histories, household deaths), and Demographic Surveillance Sites. In total, this analysis used 8259 data sources. Estimates of the probability of death between birth and the age of 5 years and between ages 15 and 60 years are generated and then input into a model life table system to produce complete life tables for all locations and years. Fatal discontinuities and mortality due to HIV/AIDS are analysed separately and then incorporated into the estimation. We analyse the relationship between age-specific mortality and development status using the Socio-demographic Index, a composite measure based on fertility under the age of 25 years, education, and income. There are four main methodological improvements in GBD 2017 compared with GBD 2016: 622 additional data sources have been incorporated; new estimates of population, generated by the GBD study, are used; statistical methods used in different components of the analysis have been further standardised and improved; and the analysis has been extended backwards in time by two decades to start in 1950. Findings: Globally, 18·7% (95% uncertainty interval 18·4–19·0) of deaths were registered in 1950 and that proportion has been steadily increasing since, with 58·8% (58·2–59·3) of all deaths being registered in 2015. At the global level, between 1950 and 2017, life expectancy increased from 48·1 years (46·5–49·6) to 70·5 years (70·1–70·8) for men and from 52·9 years (51·7–54·0) to 75·6 years (75·3–75·9) for women. Despite this overall progress, there remains substantial variation in life expectancy at birth in 2017, which ranges from 49·1 years (46·5–51·7) for men in the Central African Republic to 87·6 years (86·9–88·1) among women in Singapore. The greatest progress across age groups was for children younger than 5 years; under-5 mortality dropped from 216·0 deaths (196·3–238·1) per 1000 livebirths in 1950 to 38·9 deaths (35·6–42·83) per 1000 livebirths in 2017, with huge reductions across countries. Nevertheless, there were still 5·4 million (5·2–5·6) deaths among children younger than 5 years in the world in 2017. Progress has been less pronounced and more variable for adults, especially for adult males, who had stagnant or increasing mortality rates in several countries. The gap between male and female life expectancy between 1950 and 2017, while relatively stable at the global level, shows distinctive patterns across super-regions and has consistently been the largest in central Europe, eastern Europe, and central Asia, and smallest in south Asia. Performance was also variable across countries and time in observed mortality rates compared with those expected on the basis of development. Interpretation: This analysis of age-sex-specific mortality shows that there are remarkably complex patterns in population mortality across countries. The findings of this study highlight global successes, such as the large decline in under-5 mortality, which reflects significant local, national, and global commitment and investment over several decades. However, they also bring attention to mortality patterns that are a cause for concern, particularly among adult men and, to a lesser extent, women, whose mortality rates have stagnated in many countries over the time period of this study, and in some cases are increasing

Newer Molecular Targets in Papillary Thyroid Cancer

Thyroid cancer is the most common endocrine malignancy and its incidence is rising all over the world. If the current rapidly increasing trends continue, it will be the fourth most common cancer by 2030 (Rahib et al. 2014). The incidence of cutaneous melanoma is also rising at a fast rate although its incidence varies greatly between countries (Leonardi et al. 2018). Australia has the highest incidence of melanoma in the world and melanoma is often referred to as the national cancer of Australia. A few case reports described individuals having both thyroid cancer and melanoma. Furthermore, some genetic mutations detected in thyroid cancer are also found in melanoma. Clearly, the co-occurrence of thyroid cancer and melanoma in the same individual is an interesting area to explore. In this thesis, the aims were to i) investigate the association between molecular genetic profile, (specifically BRAF, TERT, PD-L1) and risk of recurrence and response to treatment in a cohort of patients with PTC and ii) examine the same molecular genetic profile in patients with both PTC and malignant melanoma (PAPMEL). Protein expression of PD-L1 was examined by immunohistochemistry in both cohorts and the presence of a tumour predisposition syndrome was determined by presence or absence of BAP1 in the PAPMEL cohort. The patients for these studies were identified from within the cohort of patients attending the Endocrine clinic at the Royal Alfred Hospital (RPAH), Camperdown, Sydney. There were two cohorts, a cohort with PTC only and a cohort of 21 patients with both PTC and Melanoma. The PTC cohort were stratified into High, Intermediate and Low risk patients based on clinical and histological data according to the ATA guidelines 2015. The response to treatment of PTC was also stratified into excellent, indeterminate, biochemical incomplete and structural incomplete response based on the ATA guidelines 2015. In the study involving the PTC cohort with 147 patients, the female to male ratio was 2.2 :1. Half had low risk of recurrence and 33% had high risk of recurrence with the remaining 17% being intermediate risk. As expected, majority of low risk of recurrence PTC had an excellent response to treatment whilst the majority of those with high risk of recurrence had evidence of persistent disease with structurally incomplete response. The most common mutation found in this cohort was BRAFV600E which was seen in 62% of PTC tumours. The BRAF mutation was present in 68% of those with the classic variant, predominantly in females and at an older age compared to those without a BRAF mutation. On the other hand, an NRAS mutation was present mainly in those with the follicular variants (83%) and was equally present in males and females and was seen in those diagnosed at an older age (59.6+14.2 years) when compared to the BRAF mutation (52.015.9 years) in those with the same variant. With regard to staining for PD-L1, the majority of the PTC tumoural tissue stained negative for PD-L1. Relatively less extra-thyroidal extension (ETE) was seen in the group that showed 10% and also 5% PD-L1 staining as compared to the group that showed 1% <10% and 1% to <5% staining which is an interesting observation. PD-L1 staining thresholds of <5% and 5% were significantly associated with the size of tumour. More intense staining was seen as the size of tumour increased. The association between PD-L1 staining was significant for histological variants; majority of classic variants and follicular variants stained <5%. In the PAPMEL cohort, there were 21 patients with both PTC and melanoma, all were Caucasian and the female to male ratio was 1: 1.3. In all cases, the melanoma was diagnosed prior to the PTC for melanoma. Regarding the PTC tumours, 33% had high, 29% intermediate and 38% low risk of recurrence. The majority had an excellent response to treatment. The most common mutation found in this cohort was the BRAFV600E which was seen in 88% of the PTC tumours and 37.5% of the melanomas. The NRAS mutation was seen in only 12% PTCs, compared with 37.5% in melanomas. In the 7 patients where data was available for both tissues, concordant mutations in BRAF was seen in only 2/7 (29%) patients. The most common mutation in both tissues was BRAF which was seen in 6/7(86%) of PTC and 3/7(43%) of melanoma tissues. The majority of the PTC tumoural tissue stained negative for PD-L1 and a significant association was seen between PD-L1 negative status and multifocality and bilateral tumours. BAP1 staining was retained in majority of PTCs and melanoma tissues and there was no suggestion of loss of BAP1 protein thus making presence of BAP1 tumour predisposition syndrome unlikely although 11 patients had presence of at least one other cancer apart from PTC and Melanoma. Like other studies, in PTC, the most common mutation was BRAFV600E and was associated with the classic variant. Significant association between mutation status was seen with age at diagnosis, gender and histological variants. The majority of the PTC showed negative and low staining intensity for PD-L1 expression. Of interest, relatively less extra-thyroidal extension (ETE) was seen in the group that showed 10% PD-L1 staining as compared to the group that were categorised to either 1% <10% or 1% to <5% staining. In the PAPMEL cohort, we observed a higher incidence of the BRAF mutation than commonly reported in the literature (83%). Interestingly, in the PAPMEL cohort, concordant mutations were found in only 2 of the 7 patients where data was available for both tissues and there was no suggestion of a tumour predisposition syndrome although 11 patients had presence of at least one other cancer apart from PTC and melanoma

Matters of the desert: A perspective on achieving food and nutrition security through plants of the (semi) arid regions

The semi- and arid agro-climatic zones of India harbor numerous plants, many occurring as wild and neglected inhabitants of the desert landscape, that bear edible fruits. They are capable of growing in extreme temperatures, on marginal lands and water-scarce conditions. These also represent sustainable food sources for the future. The benefits that they confer to the ecosystems and communities can be manifold: (a) as influencers of agricultural productivity for other crops (like cereals) in agroforestry systems; (b) as balanced functional foods by way of providing high quality protein, macro- and micronutrients to target protein-calorie malnutrition; (c) as sources of antioxidants, nutraceuticals and bioactive leads to target the ever-increasing burden of non-communicable diseases like obesity, diabetes and cardiovascular disorders. A few representative examples of the promising desert plants include: Prosopis cineraria, Acacia senegal, Cyamopsis tetragonoloba (cluster bean), Capparis decidua, Ziziphus mauritiana (Indian jujube), Cordia dichotoma, Leptadenia pyrotechnica, Calligonum polygonoides, and millets. Even though the potential of such plants has been recognized by food and agricultural scientists, research gaps like low yield, disease vulnerability, presence of anti-nutrients, unavailable genomic sequence information, exclusion from the formal food value chain, and poor marketing strategies, prevent the realization of their full potential. The current perspective looks at the promise afforded by underutilized plants of the Indian desert regions in ensuring food and nutrition security as well as the possibility of developing value-added agri-food products from them. The complementary role that food processing technologies can play in achieving the desired goals would also be highlighted so as to transform the desert plants from traditional to ‘climate-smart’ future foods

Not AvailableThe predatory potential of two anthocorid predators, Blaptostethus pallescens Poppius and Anthocoris muraleedharani Yamada on cotton mealybug, Phenacoccus solenopsis Tinsley and papaya mealybug, Paracoccus marginatus Williams and Granara de Willink was studied under laboratory conditions. During the nymphal stage, A. muraleedharani could feed on a total of 66 crawlers of P. solenopsis and the adult consumed 141 crawlers. Young nymphs (3-4 day old) of B. pallescens could not predate on P. solenopsis, crawlers, while, the mature nymph could consume 35 P. solenopsis crawlers and adult 23 crawlers. B. pallescens could feed on P. marginatus and the feeding potential was recorded as 18, 29 and 31 crawlers, for young nymph, mature nymph and adult, respectively. However, the longevity of B. pallescens was found significantly reduced when fed on P. marginatus. A. muraleedharani could not predate on P. marginatus. Though B. pallescens could predate on both mealybug species, A. muraleedharani appeared to be a more voracious predator of P. solenopsis based on its greater predatory potential, higher adult longevity and shorter nymphal duration.Not Availabl
