An international, interlaboratory ring trial confirms the feasibility of an extraction-less “direct” rt-qpcr method for reliable detection of sars-cov-2 rna in clinical samples

Reverse transcription–quantitative polymerase chain reaction (RT-qPCR) is used worldwide to test and trace the spread of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). “Extraction-less” or “direct” real time–reverse transcription polymerase chain reaction (RT-PCR) is a transparent and accessible qualitative method for SARS-CoV-2 detection from nasopharyngeal or oral pharyngeal samples with the potential to generate actionable data more quickly, at a lower cost, and with fewer experimental resources than full RT-qPCR. This study engaged 10 global testing sites, including laboratories currently experiencing testing limitations due to reagent or equipment shortages, in an international interlaboratory ring trial. Participating laboratories were provided a common protocol, common reagents, aliquots of identical pooled clinical samples, and purified nucleic acids and used their existing in-house equipment. We observed 100% concordance across laboratories in the correct identification of all positive and negative samples, with highly similar cycle threshold values. The test also performed well when applied to locally collected patient nasopharyngeal samples, provided the viral transport media did not contain charcoal or guanidine, both of which appeared to potently inhibit the RT-PCR reaction. Our results suggest that direct RT-PCR assay methods can be clearly translated across sites utilizing readily available equipment and expertise and are thus a feasible option for more efficient COVID-19 coronavirus disease testing as demanded by the continuing pandemic.

Evaluation of diabetes mellitus type 2 effects on kidney function

Type 2 Diabetes mellitus contributes to the development or progression of many chronic and age-related pathological processes. One of the major risk factors for morbidity and mortality among patients with diabetes is renal and vascular disease as well as heart disease. Type 2 diabetes mellitus was associated with a significantly increased age of kidney disease with higher urea and creatinine levels. 76 Libyan subjects participated in the study. The subjects were divided into three categories. One group hosts diabetes case (n=40) while the other group serves as a control (n=12) and the other group has no type 2 diabetes mellitus but urea and creatinine levels are elevated (n=36). After oral informed consent of the study participants, 5 ml of venous blood was drawn under sterile conditions for whole blood analysis. Fasting blood sugar was analyzed. Urea and creatinine levels were compared between diabetic and non-diabetic patients. However, a statistical analysis was performed using IBM SPSS version 26 where the correlation between parameters was analyzed by an independent samples t-test. In this study, patients with type 2 diabetes mellitus caused a significant increase in urea and creatinine compared to the control group. The study indicated that type 2 diabetes mellitus increases the damage to the kidney function.

Whatsapp- messenger fever on students

WhatsApp is mobile application which allows exchange of messages, videos, audio’s and images via Smartphone. The increased use of IM on phones has turned to be goldmine for mobile and computer age. This paper focuses on understanding experimental viewpoint about the intensity, usage of whatsapp messenger and its impact on the academic performance of students in institutions. Instead of fast communication and enhancing effective flow of information and idea sharing among students, whatsapp has actually impacted in some pessimistic performance of students. For instance it takes up much of the students study time resulting in procrastination related issues , destroys students’ linguistic skills, leads to lack of concentration during lectures, results in difficulty in balancing online activities (whatsapp) and intellectual preparation and distracts learner from completing their assignments and adhering to their private studies time table. It is very userfriendly and easy to get initiated. Simply enter the telephone number of the device into the app. It then sorts through the contacts (with your permission) on the phone to figure out who else also has the app already installed. Users can then invite more contacts or go ahead and start sending messages to the ones that the app discovered. Brian Acton and Jan Koum (2009) invented Whatsapp messenger for easy and fast communication and distribution of multimedia messaging. Whatsapp is one of the trend and fashion in technology that is commonly used on specific mobile phones and computers. Since the Smartphones became popular, many messaging services were launched but Whatsapp has become widespread among them. The service is available free for one year and later user has to pay very less annual amount. Besides all, this Application is highly fanatic and can create a great impact on regular users, and apart from that it can leave a trace that becomes difficult to control and cure. With whatsapp messenger, communication through mobile phones has become easier, faster and cheaper. It is less expensive as compared to the normal phone messaging. An individual can chat with friends and family overseas through whatsapp without having to incur global SMS charges.

Cerebrospinal fluid leakage post-lumbar puncture: a narrative review

Cerebrospinal fluid (CSF) is critical in maintaining brain interstitial fluid balance and providing hydromechanical protection. Lumbar puncture (LP) is a common invasive procedure for obtaining CSF samples to evaluate central nervous system infections and cancers and measure intracranial pressure. While LP is generally considered safe, it is associated with both minor and major complications. Post-LP meningitis occurs in approximately 50% of spinal anesthesia cases and 9% of diagnostic LPs. Additionally, over 70% of diagnostic LPs result in minor bleeding, which can lead to serious outcomes such as spinal epidural hematoma, nerve damage, or paralysis. Significant consequences of LP include headaches and hearing loss; however, other rare complications, such as cerebral herniation and CSF leak syndrome, must be considered carefully. This review synthesizes findings from multiple studies published in PubMed, Google Scholar, and Scopus, highlighting the need for further research on the complications and interventions related to this commonly performed procedure.

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 (10 mg) 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.

Mechanical and metallurgical properties of hybrid composite material

Tremendous growth has been incorporated in the field of composite materials in the current scenario where the engineering applications are highly demandable. Currently composites are being used to replace conventional metallic materials in a wide range of industries including aerospace, defense, aircraft, and textile which require structural materials with high strength-to-weight and stiffness-to-weight ratios. Also natural fiber composites are currently replacing synthetic fiber composites of different applications in various engineering industries due to their low cost and eco-friendly in nature. In this work, twisted kenaf, and twisted kevlar (aramid fibers) have combined together to enhance the mechanical properties and also to improve high impact resistance with less contribution of kevlar which is very high in cost categorized next to carbon fibers. Here, the hybrid composites (natural and aramid) are done by using hand layup method, and various mechanical properties have been investigated. Also, the morphological analysis is done to observe the internal structure of the tested composite. It is observed that hybrid composite has high strength with minimum contribution of kevlar fibers.

“the person with maximum knowledge will win the race”: conceptualizing knowledge in microbusinesses

The concept of knowledge and the process of knowledge sharing in ethnic minority microbusinesses remain neglected in contemporary debates even if their role for economic development is recognized. Drawing on a culturalist view, we explore how knowledge is defined and shared in a local niche market. Thematic analysis of semistructured qualitative interviews with 32 owner managers and 11 employee-managers reveals that, contrary to studies on larger firms, local knowledge creation and sharing narrowly based on ethnic strengths are valuable sources of competitive advantage. Our study has implications for researchers, policymakers, and practitioners in exploring, supporting, and integrating ethnic minority microbusinesses.

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.

Livestock plays a significant role in the economy of a nation but its productivity can be hampered by numerous haemoparasites thereby leading to economic losses to the livestock industry. The prevalence of haemoparasite in cattle slaughtered at the Jalingo abattoir was investigated. A total of four hundred blood samples were collected at the point of slaughter, processed, and screened for haemoparasites by examining Giemsa-stained thin blood smears. An overall prevalence of 12.25% was recorded. Four haemoparasites of cattle with prevalence rates of 5.0%, 6.75%, 0.25%, and 0.25% for Anaplasma, Babesia, Microfilaria and Trypanosoma respectively were observed. The prevalence of haemoparasite in relation to sex, revealed higher infection in females (13.75%) than in males (10.0%) which were not found statistically different (P > 0.05). All breeds encountered during the study were infected with haemoparasites with the highest prevalence of 13.91 % recorded in White Fulani, Red Bororo (10.94%), and Sokoto Gudali (10.00 %), while Adamawa Gudali had the least prevalence of 0.5%. There was no statistically significant difference in the prevalence of haemoparasite in relation to breeds (P > 0.05). High prevalence was observed in the young (14.29%) more than the adult (11.59%) and older (12.14%). The current study has revealed the haemoparasites status in cattle slaughtered at Jalingo abattoir. Therefore, there is a need for effective preventive and control policy of these haemoparasites to enhance livestock productivity
