Through the records of herbal and market investigations,the samples collected from different market and origin were analyzed,and the appearance character indexes were determined in order to revise the commodity specification and grade standard of Dipsaci Radix combined with production practice. This is also to analyze association of the appearance with quality different of intrinsic components. The investigation results indicated the root's long and thick was better,and atrovirens of fracture surface,there are most of the market is dominated by the ungraded goods. Through principal component analysis,variance analysis and cluster analysis,combining with the feasibility of actual operation and herbal record,the length,middle diameter and phloem color were filtrated and the specification was divided into 2 ranks: the selection and ungraded goods,and the grade was divided into 2 ranks for the selection goods: big,small selected goods. Moreover,there were no significant correlation between the appearance and the intrinsic quality index of Dipsaci Radix,the content of extractum were significantly positive correlation with the moisture,but had extremely negative correlation with the total ash. Multiple comparisons indicated that the content of the moisture,extractum and asperosaponin VI of the selected goods were higher than the ungraded goods,while the total ash content were lower,and they hasn't significant difference. The commodity specification and grade standard of Dipsaci Radix as a basis provide commodity specification and grade standard of communities and standardizing market trade order.

Background: Evidence from multiple pilots and post-introduction scale-up initiatives have demonstrated that self-administered subcutaneous depot-medroxyprogesterone acetate (DMPA-SC) has potential to improve contraceptive continuation rates and expand contraceptive access to populations with limited utilization of facility-based health services. Only a few of these studies have been conducted in South Asian countries, and none where most contraceptive use is of non-hormonal methods that require limited to no contact with the health system, leaving policymakers in countries like Pakistan with limited context-specific evidence to guide decisions on whether, how, and for whom to introduce DMPA-SC.
Methods: A prospective cohort study will be conducted in 41 health facilities and surrounding communities in Punjab, Pakistan.

Background: Previous studies involving cleanup via conventional solid-phase extraction (SPE) materials to overcome matrix effects for the polar organophosphonate and -phosphinate pesticides glyphosate, glufosinate, ethephon, fosetyl, and their various metabolites often showed limitations due to the existence of various matrix compounds in plant commodities with similar polarity. To overcome existing drawbacks, we utilized the unique selectivity provided by metal oxides as SPE materials. These were exploited in a novel automated online SPE-LC-MS/MS method which allowed analyte-specific trapping in the presence of excessive amounts of matrix compounds as typically contained in extracts of the Quick Polar Pesticides (QuPPe) method.

Background: Aflatoxin B1 (AFB1) stands among the most toxic naturally occurring substances, with its acute toxicity characterized by the induction of acute hepatic necrosis, hemorrhage, and even fatal outcomes, thereby posing a profound threat to human health. Contamination of AFB1 in food commodities can arise at multiple stages throughout the production cycle, including cultivation, storage, and processing. This contamination cascade permeates the entire food supply chain, encompassing primary agricultural products as well as a diverse range of processed food items.

Sri Lankan cinnamon, widely known as true cinnamon (Cinnamomum verum), is a world-renowned commodity. With the high market demand, many incidents have reported adulteration of true cinnamon with other cinnamon species such as Cinnamomum aromaticum, Cinnamomum burmanni, and Cinnamomum loureiroi. Moreover, the contamination of cinnamon products with fungi (Aspergillus flavus) has also significantly negatively impacted the cinnamon export market.

Klebsiella pneumoniae is a bacterium of public health importance due to its association with antimicrobial resistance (AMR) and its role as a major cause of both hospital- and community-acquired infections. While Klebsiella species have been detected in foods, our understanding of their diversity and the potential risks they pose from food is limited. This study aims to comprehensively evaluate the Klebsiella species population and their contribution to the burden of AMR, virulence, and heavy metal tolerance from diverse food samples.
