Post-market surveillance of natural health products in canada

Market trends indicate that natural health products are being used to maintain health as well as prevent and treat many medical conditions. A recent Canadian survey showed that 71% of the Canadian population have used a natural health product. Among these, many reports that they take natural health products on a daily basis. This review emphasizes on Canadian post-market surveillance system that apply to natural health products for human use. The public's perception is that the natural health products are all-natural, safe and effective, but there is still a wide variety of harms linked with these products. The post-market surveillance system is the monitoring window to observe and control the adverse effects of using natural health products. There are many activities involved in the post-surveillance to ensure the quality of the approved natural health products. Despite the fact that post-market surveillance plays a very important role in eliminating and/or reduce the risk of using natural health products, there are still some challenges and more work to be done to improve the outcome of the post-market surveillance of the natural health products.

Selection of potential isolates of plant growth promoting rhizobacteria (pgpr) in conferring salt tolerance under in vitro

Salinity is a major environmental stress which has been studied extensively and has its impact on agriculture in the past, present and future. The global importance of salt affected soils can be explained by their wide distribution on all continents covering about 10% of the total land surface. At present, there are nearly 954 million ha of saline soils on earth’s surface. It is extremely difficult to quantify the social and economic costs of salt prone land and water resources. Plant Growth Promoting Rhizobacteria (PGPR) is a group of bacteria that actively colonize plant roots and increase plant growth and yield. They play an important role within the interaction between soil and plant. As plants grow on marginal soils such as saline soils, the importance of the rhizobacteria increases as they mobilize nutrients and provide tolerance ability to the plants. In the present study, an attempt was made and isolated 51 PGPR isolates (Phosphate Solubilizing Bacteria–18; Azotobacter spp.-16 and Azospirillum spp.-17) from different salt affected areas in Tamil Nadu and Puducherry. All the isolates were screened for their efficacy against different sodium salts namely sodium chloride, sodium citrate and sodium sulphate. It was observed that the absorbance of the culture broth grown in salt stress to sodium chloride decreased with increasing concentration of the salt. Similarly decrease in growth pattern in terms of the absorbance was also observed in salt stress to sodium citrate and sodium sulphate.

Critical process parameters evaluation of modified nanoprecipitation method on lomustine nanoparticles and cytostatic activity study on l132 human cancer cell line.

This work was focused on identification and evaluation of process parameters of modified nanoprecipitation method, for fabrication of lomustine nanoparticles, with the aim of reducing cancer cell viability at low concentration of lomustine. The parameters controlling particle size, mostly in nanosize, were solvent/nonsolvent composition and emulsification speed of homogenizer along with aqueous phase volume. This controlled particle size is below 250 nm. The stabilizer concentration controlled particle size is within 68 nm ± 0.89 to 137 ± 0.94 nm with PDI 0.06 ± 0.008 to 0.25 ± 0.001. But, the stabilizer addition mode showed more uniform size distribution with PDI 0.085 ± 0.004. Entrapment efficiency was maintained well above 47 ± 0.23%. The drug release pattern was monophasic with controlled release over 24 hrs. In the method used, drug content was affected by ratio of polymer to drug to organic solvent, as well as homogenization speed and time. Percentage viable cells of L132 human lung cancer cell line remained, were only 5% at 100 μg/ml lomustine equivalent PLA nanoparticles.

Optimization of process parameters for injection moulding of nylon6/sic and nylon6/b4c polymer matrix composites

In this research study, the mechanical properties of several Polymer matrix composites are investigated. These composites are multi-phase materials in which reinforcing materials are properly mixed with a polymer matrix. More precisely, Nylon 6 reinforced with 5, 15 and 25 wt. % of silicon carbide (SiC) and Nylon 6 reinforced with 5, 15 and 25 wt. % of boron carbide (B4C), prepared by means of an injection moulding process at three different injection pressures are considered. Specific attention is paid to the tensile and impact strength of these composites. The Taguchi technique is used to optimize the process parameters such as reinforcement material, its percentage and the injection pressure. It is observed that the specimens 5% SiC with 80 MPa injection pressure display a better tensile strength and similarly the specimen 5% B4C with 90 MPa injection pressure have a superior impact strength.

Preparation and characterization and biodistribution studies of lomustine loaded plga nanoparticles by interfacial deposition method

The incorporation of lomustine, a hydrophobic anticancer drug into PLGA nanoparticles by interfacial deposition method was optimized. Based on the optimal parameters, it was found that lomustine-PLGA nanoparticles with acceptable properties could be obtained. Optimization of formulation variables to control the size and drug entrapment efficiency of the prepared nanoparticles seems to be based on the same scientific principles as drug-loaded nanoparticles prepared by nanoprecipitation, solvent evaporation method. The process was the most important factor to control the particle size, while both the drug-polymer interaction and the partition of drug in organic and aqueous phases were the crucial factors to govern the drug entrapment efficiency. PLGA concentration at lower level (100 mg), 1:5 organic phase: aqueous ratio, 1%w/v PVA concentration, 3%w/v pluronic F68 achieved smaller particle size. Additionally, L:G ratio of PLGA 75:25, lower volume of organic solvent (1:10 organic phase: aqueous phase), higher initial drug content (10mg) enhanced the drug entrapment efficiency and maintained lomustine concentration in blood for an extended time period, elevated lomustine concentration in lungs and slowed the elimination of lomustine. The biodistribution profiles of prepared nanoparticles in albino mice showed higher plasma drug concentration for longer period of time, elevated drug concentration in lungs and slow elimination from kidney. No toxic effects of prepared nanoparticles were observed in histopathological examination of lungs and kidney. The systematic investigation reported here promises the development of PLGA nanoparticles loaded with lomustine when tested in Lung Cancer cell line L132 and toxicological/ histopathological studies in albino mice.

Will comprehensive sexuality education (cse) help in youth development?

Purpose – The purpose of this review is to critically analyse the extant research and help readers understand the ways the school-based comprehensive sexuality education (CSE) can contribute towards youth development and urge policymakers to implement nationwide good-quality, scientific, culturally relevant, age-appropriate and holistic school-based CSE. Design/methodology/approach – This literature review has been designed using the extant information available on Google Scholar, Web of Science (WoS) and PubMed. Findings – The findings of this review inform that there is a significant need amongst the youth of the day for good-quality, scientific, culturally relevant, age-appropriate and holistic school-based CSE. Also, the findings suggest that there are significant associations between school-based CSE and youth development. Research limitations/implications – This research paper although draws from extant literature about sexuality education and its delivery across the globe, it applies the sexuality education scenario in India. Practical implications – The findings of this review aim to implicate nationwide policy-level changes to implement CSE in the school curricula. There are more practical behavioural changes that CSE could foster amongst students, which are discussed in the review. Social implications – Due to the behavioural changes that CSE could foster amongst students, it may help in the upbringing of responsible citizens who are free of health complications, who can make independent health related decisions and look after each other in the community. Originality/value – This review is an original contribution from the author. Whilst there is extant literature about CSE and youth development, this article fills the void by investigating the interdependent contributions that both the concepts can make to one another and encourages more research on this topic.

Possible implications of the anthropocene on climate change and soil health

Anthropogenic and climatic factors influence soil’s physical, chemical, and biological properties, setting the stage for agriculture’s sustainability. Soil is a primary carbon sink crucial for reducing greenhouse gas emissions, making soil health essential for mitigating climate change. Healthy soil enhances climate resilience by maintaining or increasing carbon content and lowering emissions. The overuse of fertilisers pollutes the environment and inadequate application damages soil fertility and microbial activity. The conversion of forests and pastures to agricultural land has resulted in significant carbon losses from the soil. Additionally, soil sealing, air pollution, and industrial contamination all contribute to climate change. Harmful practices such as heavy tillage, land neglect, monoculture cultivation, and excessive chemical use, driven by the pressure to meet growing food demand, have led to soil compaction, degradation, pollution, and nutrient imbalances. Current mismanaged crop and soil techniques deteriorate soil quality; however, by increasing carbon storage in mineral soils and removing emissions from organic soils, sustainable management can contribute to climate neutrality. Climate change can be exacerbated by the release of carbon dioxide into the atmosphere from unsustainable farming practices and poorly managed soils. The purpose of this study is to investigate the detrimental impacts of anthropogenic (Anthropocene) effects on the environment and soil health from a comprehensive perspective and to formulate potential recommendations. The European Union’s Green Deal, Bioeconomy, and Farm to Fork initiatives aim to sustainably transform agriculture in response to climate challenges. These strategies aim to reduce chemical pesticide use by 50%, fertilizer use by 20%, and nutrient losses by 50% by 2030 to preserve soil fertility. These management practices include efficient fertilizer use to maintain soil health and mitigate climate change effects. Restoring degraded soils and implementing conservation measures can reduce greenhouse gas emissions and increase carbon storage capacity. Sustainable soil and crop management, including crop rotation, minimizing post-harvest ploughing, preserving vegetation cover, boosting organic matter, and using fertilizers sensibly, is urgently needed to minimize greenhouse gas emissions and store atmospheric carbon dioxide in soil.

A systematic evaluation of research on social engineering attacks prevention

Social engineering is a method of information security that allows for system or network access. When victims are unaware of techniques, models, and frameworks to prevent them, social engineering attacks happen. In order to stop social engineering attacks, the current research describes user studies, constructs, assessment, concepts, frameworks, models, and techniques. Sadly, there isn't any specific prior research on mitigating social engineering attacks that thoroughly and efficiently analyzes it. Health campaigns, human security sensor frameworks, user-centric frameworks, and user vulnerability models are examples of current social engineering attack prevention techniques, models, and frameworks. Guidance is required to examine cybersecurity as super-recognizers, possibly acting as police for a secure system, for the human as a security sensor architecture. This research aims to critically and systematically analyze earlier material on social engineering attack prevention strategies, models, and frameworks. Based on Bryman & Bell's methodology for conducting literature reviews, we carried out a systematic review of the available research. Using a protocol, we discovered a novel strategy to stop social engineering assaults in addition to approaches, frameworks, models, and assessments, based on our review. We discovered that the protocol can successfully stop social engineering assaults, including health campaigns, the susceptibility of social engineering victims, and co-utile protocol, which can control information sharing on a social network. This comprehensive evaluation of the research is what we're presenting in order to suggest safeguards against social engineering assaults.

Analysis on digital implementation of sigma-delta adc with passive analog components

Sigma-Delta (SD) analog to digital converters (ADCs) have several advantages over the nyquist rate type ADCs. The linearity over high dynamic range makes the SD ADCs an ideal choice for voice and precise instrumentation applications. The SD-ADC architecture is well established and analyzed [5, 6]. It is heavily based on digital processing and provides a high resolution, low noise output with very low analog implementation effort. The technique of sigma delta ADC is in practice from several decades. The feature of digital dominated design of SD-ADC makes it different from other types of ADCs. As the technologies are evolving, new realization methodologies are emerging for realizing SD-ADC. The conventional approach of realizing an ADC as a separate ASIC and providing the interface to digital IC (either Microprocessor or FPGA) for providing mixed signal processing platform has following limitations.

Dan-nucnet: a dual attention based framework for nuclei segmentation in cancer histology images under wild clinical conditions

Nuclei segmentation plays an essential role in histology analysis. The nuclei segmentation in histology images is challenging in variable conditions (clinical wild), such as poor staining quality, stain variability, tissue variability, and conditions having higher morphological variability. Recently, some deep learning models have been proposed for nuclei segmentation. However, these models rarely solve the problems mentioned above simultaneously. Most of the information in Hematoxylin and Eosin (H&E) stained histology images is in its channel, and the remaining information is in the spatial domain. We observed that most problems could be solved by considering channel and spatial features simultaneously, e.g., the spatial and channel features provide the solution to the morphological variability and staining variability, respectively. Therefore, we propose a novel spatial-channel attention-based modified UNet architecture with ResNet blocks in encoder layers. The UNet baseline preserves coarse and fine features, thus proving the solution to the tissue variability. The proposed method significantly improves the segmentation performance compared to the state-of-the-art methods on three different benchmark datasets. We demonstrate that the proposed model is generalized for 20 cancer sites, more than any reported literature. The proposed model is less complex than most state-of-the-art models. The impact of the proposed model is that it will help improve further procedures such as nuclei instance segmentation, nuclei classification, and cancer grading.

Verbal and spatial working memory among drug-using hiv-infected men and women

Working memory (WM) is a critical component of many neurocognitive functions. The literature has demonstrated consistently that WM impairment is more frequent and severe among substance-dependent individuals (SDIs) infected with HIV compared with uninfected SDIs; however, the SDIs who participated in these previous studies were primarily male. There are few published data on WM performance among HIV+ women with or without substance use disorders, and essentially no direct comparisons of WM performance between HIV+ men and women, regardless of substance use. We investigated potential sex and serostatus effects on WM among a sample of 360 SDIs (114 with HIV; 66% female) verified abstinent from alcohol and drugs of abuse at testing and generally comparable on substance use and comorbid characteristics. Participants were tested with the n-back task, a well-established WM measure that is sensitive to HIV-associated cognitive impairment. HIV+ men and women performed spatial and verbal versions of the n-back significantly less accurately compared with HIV− participants. Women showed slower response times compared with men on both versions, regardless of HIV serostatus. Individuals dependent on cocaine showed faster RTs compared with non-dependent users, but this effect was not apparent among opioid- or alcohol-dependent groups. Findings on n-back accuracy are consistent with our previous proposal that WM impairment represents a signature deficit among HIV+ SDIs; however, WM impairment appears less common among HIV+ women without a substance use history. The pattern of sex differences in response speed but serostatus effects on response accuracy is comparable to a recent report by our group of sex differences in learning speed but serostatus effects on delayed recall.

Attitude towards wearing face mask increases vulnerability of men over women and the risk of covid-19 pandemic spread in jos-south metropolis, plateau state, nigeria

Background Covid-19 pandemic has hit many countries and put the majority of the public health system to test globally. Mandatory use of face mask was among policies set by the government to contain the spread of the novel disease. But citizens’ attitudes and compliance with these policies are important in controlling the pandemic. We assessed gender-based compliance to Covid-19 protocol (use of face mask) in Jos South, Plateau State, Nigeria. Methods Perception regarding Covid-19 and the use of face masks were assessed among participants using a questionnaire-based survey. In a cross-sectional study, ninety (n=90) questionnaires were administered to willing participants directly. A Chi-square test was used to determine the descriptive analysis of all responses, P-values <0.05 were considered statistically significant. Result Out of 90 participants, 55.6% (50/90) were male and 44.4%(40/90) were female. Forty-two (84%) males deny the existence of the pandemic while in females, 14 (35%) deny that Covid-19 exist. Thirty-seven (74%) of the male respondents do not comply with to use of the face mask and use a single face mask multiple times without decontamination. In females, 28 (70%) comply with the use of the face mask. Unlike the men, 20 (50%) of the females always decontaminate the face mask. The middle-aged adult (26-45 years) uses the face mask more than the young (18-25 years). There was a significant association of gender in relation to the perception of Covid-19 and the use of facemask (p< 0.05). Conclusion Male respondents showed an irresponsible attitude complying to Covid-19 protocol than the females, therefore, enlisting them as a risk factor for the continued spread of the virus. We recommend that public health awareness and campaigns should focus and employ greater influence on men and young adults in their compliance with the preventive protocols.

New dimension in higher education in india

Higher Education has an important role in the task of rebuilding a nation and it pavCes the way for overall development of a nation. The twentieth century has witnessed several revolutions like Green revolution, White revolution, I.T revolution, so on and so forth, taking human civilization to new heights. At the start of 21st century, we gave a lot of importance given to higher education. Every country realized the value of higher education and the benefits that accrue from it. “The social demands for higher education continue to increase. The inabilities of the state to support this growing demand result in new financing arrangements for higher education. The recent reforms in this area could be broadly divided into two categories: the privatization of public institutions and the establishment of private institutions of higher education. Privatization implies the application of market principles in the operation of public institutions, while ownership rests within the public domain. Promotion of the private sector implies the growth and expansion of the non-state sector in higher education, and very often this sector does not rely on state funding for its growth and expansion. Both of these measures have paved the way for market operations in higher education

Disempowering the powerful: a critical pragmatic analysis of political discourse using brown and levinson’s face theory

Power and dominance exist everywhere and occur at the macro and micro levels. Being powerful and domineering are factors that serve as emblems for the people in the realm of politics. Power relations are overtly exercised in such discourse. But what is interesting is how power and dominance exist between or among those people who are branded as “powerful;” thus, using the Face Theory of Brown and Levinson (1978), this discourse analysis paper analyzed the power relations that transpired in a senate hearing and its relationship with the Face Threatening Acts (FTAs) used by the people involved in the discourse. A Philippine Senate hearing excerpt served as the primary corpus for analysis. Results showed that the people in the discourse were all powerful, creating tension when they projected their dominance on one another. Each member threatened and challenged their positive and negative faces. The power play evolved into a "pass-theball" effect, and no one has absolute power because it weakens once the person wielding its face is threatened. Hence, to disempower the empowered, a person must learn how to play and use FTAs such as insulting, disagreeing, disapproving, provoking, commanding, and demanding against the powerful to strike a social balance.

In vitro urolithiasis models: an evaluation of prophylactic management against kidney stones

Urolithiasis is a global health problem with a high recurrence rate. Different in vivo and in vitro models have been successfully used to evaluate the antiurolithiatic potential of medicinal plants. In vitro models study renal stone formation, and in vivo models reveal the pathological effects of urolithiasis. Thus, in vitro models are significantly and effectively used to evaluate prophylactic management, and in vivo models direct urolithiasis treatment. This paper describes the advantages, limitations and applications of both models, especially the role of in vitro studies in the evaluation of prophylactic management.
