Patients’ Perceptions of Cannabis Contamination in Florida's Medical Program

Introduction As medical cannabis becomes more accessible, product quality must be evaluated. Researchers identified a social media community where Florida medical cannabis patients discuss personal experiences. The objective of this study was to analyze posts in this community to understand patient experience with products purchased from Florida medical dispensaries they believed to be contamination, perceptions of product quality, and desired changes to the Florida program. Methods Social networking theory acted as the underlying framework, and we employed a qualitative case study design to identify mentions of possible contamination and understand patient perceptions of contamination and the Florida medical cannabis program from the Reddit community FLMedicalTrees. The lead researcher conducted a social media analysis of posts identified as containing discussions relevant to product contamination. Constant comparison methods were used to code data, arrive at themes, and maintain validity and reliability of interpretation of coded themes. Results Of 300 post mentions of contamination, 98 posts were identified as relevant following review. Key results were: 1. Multiple mentions of possible contamination for products from medical cannabis dispensaries reported by Florida program patients. 2. Patients sought second opinions when concerned about possible contamination and shared personal experiences as well as advice on what concerned patients should do if they believe they have contaminated products. 3. Some patients expressed feelings of anxiety and worry about health, safety, and quality control, while others that described possible product contamination did not express concern. 4. Patients wanted changes regarding vertical integration, company accountability, state oversight, and home grow law. Conclusions Medical cannabis patients and providers could benefit from education on responding to possible contamination within medical cannabis products. Policymakers should consider these findings when setting regulations around contamination testing thresholds, dispensary oversight, and other regulations that directly impact patient safety like allowing patients to see products before purchase.

Effect of "In Use" Administration on Topical Product Metamorphosis and Skin Permeation of Acyclovir Creams: Implications for Bioequivalence.

Typical clinical "in use" conditions for topical semisolids involve their application as a thin film, often with rubbing that can induce metamorphic stress. Yet, product quality and performance tests often characterize the manufactured product, and may not consider product metamorphosis (e.g., shear history) during dispensing and administration. This work sought to elucidate how such metamorphosis might alter product quality and performance. We evaluated the effect of "in use" stresses on drug crystal metamorphosis in acyclovir creams by optical microscopy. The amount of dissolved acyclovir was determined by separation of the cream base by ultra-centrifugation and quantification by HPLC. IVPT was undertaken on Zovirax® US and Aciclostad® comparing static and "in use" application of a finite dose. A mechanistic IVPT study was also conducted to understand the influence of acyclovir particle size reduction by "in use" rubbing on skin permeation. Reduction in acyclovir particle size was seen after "in use" rubbing with increases in the amount of dissolved acyclovir after rubbing (30 and 60s) compared to static for both products. "In use" application resulted in significantly higher acyclovir permeation from both products. The mechanistic IVPT study proved the role of product metamorphosis. These results highlight the role of metamorphosis of product microstructure and its influence on performance.

Acidification alternatives for elaborating “salchichon” (Spanish dry fermented sausage)

The acidification technique is widely used in the meat industry to increase meat product security and quality. The most popular acidified and fermented meat product is salchichon. The objective of this study was to determine the effect of alternatives to lactic acid bacteria for elaborating salchichon. Three treatments were prepared to acidify the meat product: glucono delta lactone (GDL), apple cider (SID) and a commercial starter (BAL) as control. When the meat product reached a weight loss of 35%, physicochemical parameters, microbial groups and sensory analyses were evaluated. Results indicated that pH decreased most in GDL and SID resulted in greater weight loss, while GDL showed the lowest pH value at the end of the fermentation process. There were also statistical differences in cohesiveness and resilience. Moreover, there was no presence of Salmonella or Listeria monocytogenes in any of the treatments. The sensory analysis indicated that the treatment added with apple cider scored the highest for color, while both SID and BAL were the most accepted in terms of taste. It was concluded that apple cider and glucono delta lactone can be used for acidification during the elaboration of the salchichon, as pH levels decline quickly, thereby reducing the processing time without affecting the quality of the final product

TRANSFORMATIONAL LEADERSHIP AND INNOVATION IN THE MANUFACTURING SECTOR: A MODERATION MEDIATION MECHANISM OF ORGANISATIONAL CULTURE AND KNOWLEDGE SHARING

Objective: The objective of this study was to investigate the mediation effect of knowledge sharing on the relationship between transformational leadership and innovation. The moderating role of organisational culture was also tested on the relationship between transformational leadership and knowledge sharing. Theoretical Framework: This investigation is based on the transformational leadership theory. Transformational leaders inspire people to share knowledge and create a work environment that is supported by a conducive organisational culture. Method: Based on extensive literature review, a structured questionnaire was designed, and data were collected via Google forms from a total of 510 manufacturing sector employees based in three SADC region countries. Statistical analyses were done using SMART PLS 4. Results and Discussion: The study established that while transformational leadership had a significant positive impact on innovation, knowledge sharing partially mediated the relationship between the two variables. Organisational culture had a weak but positive impact on the relationship between transformational leadership and knowledge sharing.These results support prior research findings. Research Implications: Transformational Leadership and knowledge sharing were found to be positively associated with innovation, hence, theoretically, this study validates the antecedents of innovation in a manufacturing sector context. Practically, managers in the SADC manufacturing sector must exhibit attributes of transformational leadership whilst creating a conducive organisational culture that supports knowledge sharing. Originality/Value: This study contributes to the literature by proposing and validating a mediation-moderation model that supports the impact of transformational leadership on innovation. The relevance and value of this research is evidenced by an improvement in the quality of exportable products from the SADC manufacturing sector through the transformative efforts of organisational leaders.

Highly Efficient Process for Producing a Jet-A1 Biofuel Component Through Hydroprocessing Soybean Oil over Ni and Pt Catalysts

This study presents an efficient process for producing sustainable aviation fuel (SAF) from soybean oil through hydrodeoxygenation (HDO) and hydroisomerization (HI). The research utilized a commercial nickel catalyst for the HDO step, and a newly developed platinum catalyst supported on SAPO-11 zeolite for the hydroisomerization (HI) stage. The process parameters, including temperature and pressure, were optimized to maximize conversion efficiency and meet ASTM D7566 standards. The results indicate that the HDO process using the nickel catalyst achieved a high yield of n-alkanes (97.8% ± 0.4%) with complete conversion of triglycerides. In the subsequent hydroisomerization step, the platinum catalyst demonstrated excellent selectivity for Jet-A1 fuel, yielding a bio-jet fraction of 87.5% ± 1.6% in a 200 h continuous test. This study also highlights the minimal coking phenomena and high catalyst stability throughout the process. This work suggests that soybean oil, as a readily available feedstock, could significantly contribute to the production of SAF and reduce greenhouse gas emissions in the aviation sector. Additionally, the optimization of temperature and pressure conditions is crucial for enhancing the yield and quality of the final bio-jet product.

This program shows a significant increase in employee knowledge and skills regarding the use of drying rooms. Apart from that, the drying process has become more effective and efficient from 2-3 days (during the rainy season) to 1 day (during the rainy season) and the production of dry plastic shreds ready for sale has increased by 75%.

ASFormer: Attentive Semantic Feature Fusion Transformer for Pixel -level Defect Detection

Abstract Surface defect detection is pivotal for ensuring product quality in various industries. These defects typically manifest as low background contrast, substantial variations in shape, and a scarcity of balanced training samples. Traditional defect detection methods often encounter limitations in terms of low detection accuracy and insufficient detection granularity. This study introduces an innovative attentive semantic feature fusion transformer network (ASFormer) tailored for pixel-level defect detection tasks to overcome these challenges. Initially, the transformer architecture is employed to extract the multiscale features of defects. Subsequently, a multiscale semantic fusion module is integrated, complemented by a dynamic upsampling mechanism, to mitigate the loss of detailed information during feature fusion. Moreover, a scale-aware dual-attention module is developed, which effectively captures the intricacies of the fused features across both channel and spatial dimensions, ensuring pixel-level detection precision. Additionally, a contextual boundary loss function is proposed to augment the ability of the network to discern defect boundaries, different categories and defect scales. Experimental validation on the NEU-Seg and Crack500 surface defect datasets demonstrated that the proposed ASFormer achieved state-of-the-art performance, with mIoU scores of 85.24% and 78.20%, respectively.

From Waste to Taste: Coffee By-Products as Starter Cultures for Sustainable Fermentation and Improved Coffee Quality

Utilizing coffee by-products in the fermentation process of coffee offers a sustainable strategy by repurposing agricultural waste and enhancing product quality. This study evaluates the effect of applying a starter culture, derived from coffee residues, on the dynamics of reducing and total sugars during coffee fermentation, as well as the composition of aromatic compounds, organic acids, and the sensory profile of coffee inoculated with yeast (Saccharomyces cerevisiae) and lactic acid bacteria (Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus), in comparison to a spontaneously fermented sample. Volatile compounds were identified and quantified using dynamic headspace gas chromatography-mass spectrometry (HS/GC-MS), with predominant detection of 2-furancarboxaldehyde, 5-methyl; 2-furanmethanol; and furfural—compounds associated with caramel, nut, and sweet aromas from the roasting process. A reduction in sugars (glucose, fructose, and sucrose) occurred over the 36 h fermentation period. Lactic acid (2.79 g/L) was the predominant organic acid, followed by acetic acid (0.69 g/L). The application of the inoculum improved the sensory quality of the coffee, achieving a score of 86.6 in evaluations by Q-graders, compared to 84 for the control sample. Additionally, descriptors such as red apple, honey, and citrus were prominent, contributing to a uniform and balanced flavor profile. These findings indicate that controlled fermentation with starter cultures derived from coffee by-products enhances sustainability in coffee production. It achieves this by supporting a circular economy, reducing reliance on chemical additives, and improving product quality. This approach aligns with sustainable development goals by promoting environmental stewardship, economic viability, and social well-being within the coffee industry.

Impact of input volume on red cell quality in deglycerolized RBCs using a modified ACP-215 protocol.

The ACP 215 automated cell processor is used to glycerolize and deglycerolize red cell concentrates (RCCs). Its primary advantage over the COBE 2991, previously used to cryopreserve RCCs, is that it maintains a closed system enabling extended post-thaw expiry. However, it was observed that post-deglycerolization hematocrits (Hct) of units processed with the LN236 kit are markedly lower than those processed using the COBE 2991. Therefore, we intended to determine whether a modified process using a smaller volume deglycerolization kit (LN235) could increase the final Hct with limited deleterious effects on product characteristics. Two proof-of-concept (POC) studies, conducted to determine the feasibility of using the LN235 processing kit for deglycerolization, identified the necessary modifications to the pre- and post-deglycerolization process, after which a two-part study characterized the modified protocol. The impact of pre-cryopreservation storage duration (7-21 days), input red cell mass, and the type of CPD/SAGM RCC production method (red cell filtration and whole blood filtration) were investigated. Using the LN235 kit in conjunction with a volume reduction step for RCCs with a red cell mass exceeding 180 mL allowed for an ~8% increase in Hct. As expected, slightly lower recoveries were seen for large RCCs due to volume reduction; however, there were no other detrimental outcomes on product quality. Leveraging the LN235 kit, recommended by Haemonetics for units with a red cell mass of ≤180 mL, can be used to increase the post-deglycerolization Hct of RCCs that exceed this volume.

Transcriptome-guided breeding for Paspalum notatum: producing apomictic hybrids with enhanced omega-3 content

Key messageTranscriptomics- and FAME-GC-MS-assisted apomixis breeding generated Paspalum notatum hybrids with clonal reproduction and increased α-linolenic acid content, offering the potential to enhance livestock product's nutritional quality and reduce methane emissions A low omega-6:omega-3 fatty acid ratio is considered an indicator of the nutritional impact of milk fat on human health. In ruminants, major long-chain fatty acids, such as linoleic acid (18:2, omega-6) and α-linolenic acid (18:3, omega-3), originate from dietary sources and reach the milk via the bloodstream. Since forages are the primary source of long-chain fatty acids for such animals, they are potential targets for improving milk lipid composition. Moreover, a high 18:3 content in their diet is associated with reduced methane emissions during grazing. This work aimed to develop genotypes of the forage grass Paspalum notatum with high leaf 18:3 content and the ability for clonal reproduction via seeds (apomixis). We assembled diploid and polyploid Paspalum notatum leaf transcriptomes and recovered sequences of two metabolism genes associated with the establishment of lipid profiles, namely SUGAR-DEPENDENT 1 (SDP1) and PEROXISOMAL ABC TRANSPORTER 1 (PXA1). Primers were designed to amplify all expressed paralogs in leaves. qPCR was used to analyse SDP1 and PXA1 expression in seven divergent genotypes. Reduced levels of SDP1 and PXA1 were found in the polyploid sexual genotype Q4188. Fatty acid methyl esters/gas chromatography/mass spectrometry (FAME/GC/MS) assays confirmed an increased percentage of 18:3 in this genotype. Crosses between Q4188 and the obligate apomictic pollen donor Q4117 resulted in two apomictic F1 hybrids (JS9 and JS71) with reduced SDP1 and PXA1 levels, increased 18:3 content, and clonal maternal reproduction. These materials could enhance milk and meat quality while reducing greenhouse gas emissions during grazing.

Effects of stress hormones on digestibility and performance in cattle: A review

Abstract Various stress factors affect the physiology of cattle. Environmental stressors include heat, cold, wind, humidity, nutrition, endocrine disruptors, and management. Several negative health effects are associated with the hormones produced under stress conditions. In cattle, cortisol has been associated with reduced rates of reproduction, lowered milk production, and suppression of the immune system causing greater disease susceptibility. For a better understanding of how stress hormones impact feed digestibility and animal performance, this review has been divided into four sections (feed digestibility, milk production, milk composition, and meat quality). In dairy cows, the transition period is challenging because of a shortage of energy and nutrients, inflammation, increased lipid peroxidation, as well as hormonal and metabolic changes. Stress hormones decrease milk yield, but cortisol affects arteriovenous pressure, which is essential for milk production (due to stressful conditions or other factors such as the use of steroid medicines). Higher cortisol levels have been observed in the hotter and more stressful months of the year. On the other hand, in early lactation, reduced feed intake can lead to acidosis, reduced milk fat, and lameness in cattle. Heat stress (HS) influences milk composition negatively, especially a decrease in milk protein. In fattening animals, HS reduces feed intake, animal growth, and production efficiency. These extreme events have short-term effects and can last a day or two. Practical solutions can be adopted to reduce HS by modifying the diet, increasing the amount of water for drinking, providing shade, and a good air exchange in the barn and installing sprinklers. It is possible to increase animal welfare and product quality based on the conclusions of this review.
