UNDERSTANDING OF ORGANIC FOOD SYSTEM THROUGH ORGANIC FOOD COMPETITIVE MODEL (OFCM)

A dynamic progress of the organic food system as a sustainable agriculture has renowned globally. However, there is little investigation on factors integration in organic food system particularly for its holistic understanding of environmental, economic and social benefits. This paper integrates and synthesizes the findings of published research and it proposes a conceptual model known as Organic Food Competitive Model (OFCM). The OFCM as first of its kind of integrated model with objective to realize and recognize the broader significance of organic food system to academicians, practitioners and policy makers particularly for developing countries like Pakistan. In addition, the OFCM descriptively highlights three interdependent components including consumer motives, supply chain, and government intervention specifically in marketing and public policy perspective. It further discusses the antecedents and horizon of organic food system which include sustainable farming, certification, entrepreneurship, international trade, local market development and impact of organic food on human capital. Finally, the article concludes and offer future research directions on organic food in the domain of marketing and policy.&nbsp

PROSPECTS AND CHALLENGES IN THE DEVELOPMENT OF ORGANIC FOOD POLICIES AND PRACTICES IN PAKISTAN A MARKETING PERSPECTIVE

Little is known about role marketing towards sustainable agriculture. This study seeks to contribute in the literature of marketing in public sector agri-organizations. The primary objective of this paper was to explore the role of marketing in the development of organic agriculture policies and practices. Based on qualitative research method, using a case study approach, data triangulation was applied to validate the findings. Interviews were conducted in six federal government agriculture institutions. The results indicate that Pakistan could not materialize its potential of organic agriculture. Apart from that, several barriers in the development of organic food policies and practices were also revealed in marketing context. These include insufficient marketing experts, lacking in marketing boards, inadequate marketing communication, ineffective strategic marketing planning, insufficient marketing, and consumer research. The findings of this paper recommended that marketing can contribute significantly to assist policy makers in adapting realistic and rationale approach towards developing organic food industry in non-regulated markets generally and in Pakistan particularl

Hemoglobin adducts in paint industry workers: An electrophoretic analysis

Background: Hemoglobin (Hb) has a significant role among other blood proteins vital for carrying nutrients to blood cells. Being a conjugated protein, Hb is prone to be captured by compounds of low molecular weight like organic acid anhydrides (OAAs) which are prominent industrial/occupational hazards. Hindered or lowered availability of Hb to blood cells can cause anemia, thalassemia and porphyria. Along with these disorders, workers exposed to OAAs can also acquire like type-I allergy, type-IV allergy, skin problems, rhinitis and asthma. Revelation of Hb-OAAs compounds prior to appearance of actual symptoms could be important for subsequent therapy.Methods: The Hb separation was achieved successfully by SDS-PAGE electrophoresis on 10-15% gels of different concentration, stained with CBB-R250 Blue. Total of 66 blood protein samples were used for the comparative study of exposed workers of paint industry workers with control (normal) group to detect proteins, which might serve as marker for the early disease diagnosis.Results: The better Hb separation resolution was achieved on 12% gel as shown in electrograms. The electrograms of paint workers exposed to OAAs showed bands at 12, 48, 66, 78, 128 and 132 KDa in most of cases. In normal cases the bands were found at 13, 30, 48, 67, 76, 125 and 155 KDa in majority of control samples for Hb electrophoresis.Conclusion: This study supports the association between Hb and OAAs adducts among the exposed paint workers from hypersensitive effects like fever (rhinitis) leading to asthma, skin allergies and major clinical effects.

Histomorphometric Effcets of Oral use of Tobacco in Testes of Offsprings of Swiss Albino Mice

Objective: To study the gross micro structural changes in the testis of the offspring of Swiss albino mice exposed to oral use of tobacco during pregnancy. Study Design: Experimental Duration and Setting of Study: This study was conducted from July 2017 to December 2017 at Isra University Hyderabad  Methodology: ­­20 female albino mice were mated. After confirmation of pregnancy by vaginal plug they were divided into two groups; experimental A and control B of 10 each. Experimental mice of group A were given 5% tobacco in their chow diet and0water ad libitum; however, control group B were given only normal chow0diet and0water0ad libitum. After 15 days of birth the 10 male offsprings each of control and experimental mice were randomly selected. Their initial and final body weight was recorded.  They were sacrificed0by cervical dislocations and0their testes were taken away for further gross & histological0analysis.  Results: Noticeable changes were observed in the body weight and weight of testes. The mean initial weight of experimental male offspring was found to be 1.76 ± 0.33 g, while in control group it was 2.60± 0.45 g. The final weight in experimental offspring was 9.38± 0.59 g and in control group it was 12.75±0.96 g.  Statistically the difference of body weight in offspring was found to be significant (p value <0.05). The testes weight was markedly decreased in experimental group as compared to control group.  The mean testes weight in experiment group was recorded as 0.03 ± 0.004 g however in control group it was recorded as   0.07 ± 0.004 g. Simultaneously, 5 micro structural variations were also observed in the testes of off-springs of mice. In0the0experimental group0of off-springs, very few0layers and decreased number of spermatocytes were noticed in seminiferous tubules of 9 testes.  Sperm degenerative changes, cellular inflammation and mild to massive hyalinization were noticed in 9, 6, and 9 testes of experimental group respectively. Loss of architecture of seminiferous tubules in 8 testes as well as destruction of the basement membrane in 7 testes were also observed in experiment group testes. However, the decreased number of spermatocytes in only 1 testes and mild hyalinization in 2 testes of control group were observed. Conclusion: The consumption of smokeless tobacco has vital effects on the body weight, micro structure  and weight of testes of offsprings of mice given with cellular injury of seminiferous tubules especially decreased sperm count, cellular inflammation, destruction of basement membrane as well as massive hyalinization. &nbsp

Demographic profile and associations of dialysis dependent chronic kidney disease patients in federal capital of pakistan.

Depression is quite prevalent in patients with chronic kidney disease. Knowing the frequency of depression in such patients and its association with different variables may be helpful in devising strategies for better and timely management of such patients in our setup. Materials and methods: This cross sectional study was conducted by recruiting 315 patients of either gender, ≥ 18 years of age with chronic kidney disease (CKD) and receiving care at Pakistan Institute of Medical Sciences, Islamabad. Patients were divided into two groups; group A: pre-dialysis and group B: dialysis (End Stage Renal Disease). Prevalence of depression in CKD and dialysis group and its association with gender, level of formal education and socioeconomic status was evaluated using descriptive statistics and chi-square test. Results: Out of 204 (100%) patients in group B, 171 (83.8%) patients had depression while in group A, 68 (61.3%) out of 111 (100%) patients were depressed. The prevalence of depression in all stages of CKD combined was 75.87 % (239 out of 315) and that in dialysis group was 83.82% (171 out of 204). Frequency of depression was significantly higher in the dialysis group (p=0.01). Those with higher level of education less commonly suffered from depression (p=0.01). No such association was found with gender (p=0.68) or socioeconomic status (p=0.12).Conclusion: Frequency of depression is significantly higher in dialysis dependent CKD patients with an overall prevalence of 75.87% in CKD and 83.82% in dialysis dependent ones. Higher level of formal education positively affects the outcome while gender and socioeconomic class have no significant association

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

An approach for SE personal from academics towards real time market

This research paper discusses the software engineering field. In which many problems exist because the software engineering field consists of different nodes and each node in turn contains a unique field. The paper also explores problems within the software engineering field as well as the market situation and the reasons behind the software engineering field in Academia are lagging behind. Here some guidelines are presented for Academia as well as industry for the improvement/help of the software engineers. The implication of an increasingly geographically mobile workforce mean that students educated in Asian regions, in particular, are facing problems due to differences in their education and culture from those in the West. In addition we present several issues concerning online studies vs. traditional studies and analyze the finding

Seasonal And Regional Effects of Air Quality Index on Hematological Indices of Dogs Under Local Environmental Conditions In Pakistan

Air pollution is found to have significant association with living health all over global world. Environment Protection Department of Punjab, Pakistan provides the monthly air quality index (AQI) data on air pollution with concentrated particulates like PM2.5, PM10, NO2, SO2 and O3. Air particulates concentrations may vary of season, regional geography and climate. We performed blood sampling of 45 dogs from different breeds (Labrador retrievers, German shepherds and Pit bulls) from three different areas categorized on basis of AQI as less polluted (Gulberg), polluted (Town Hall) and highly polluted (Shadman) in winter and spring seasons. Data were analysed using paired sample t-tests for seasonal study and independent sample t-tests for area and breed study by SPSS (P < 0.05 ascertained as significant). Seasonal study resulted that less polluted area had no significant effects on hematological indices in any three breeds of dogs in both seasons. Polluted area was presented with increased significant effects on values of monocytes in Labrador retrievers, Hct and MCHC in German shepherds while decreased significant effects on MCH value in Pit bulls in winter season as compared to spring season. Highly polluted area had significant effects with decreasing WBC counts only in German shepherds in winter season than spring season. This study concludes that polluted and highly polluted areas in winter season with worst AQI affects blood indices more than spring season in dogs
