Two New Ant-Eating Spider in the Genus Mallinella Strand, 1906 (Araneae: Zodariidae) from Tingloy Island, Batangas, Philippinesa
Authors: Barrion Alberto T , C Lualhati-Caurez
Published: May 2024

Two new species from the genus Mallinella Strand, 1906 (Zodariidae) were collected from Barangay Sto. Tomas of the island municipality of Tingloy, Batangas, Philippines from January to June 2018 through the use of pitfall traps. Male and female genitalia of Mallinella tingloy n. sp. and Mallinella marikaban n. sp. were observed and documented in details including their specific posterior ventral spines (PVS), a shared character among Mallinella spiders. This faunistic exploration and inventory of Zodariidae revealed that Mallinella tingloy n. sp. and Mallinella marikaban n. sp. are the sixth and seventh Mallinella species collected and recorded in the Philippines, respectively, and the first recorded species of Mallinella in the province of Batangas and in the island municipality of Tingloy. The new taxa are hereby described and photographs are provided to facilitate species identification. Diagnosis of each species is summarized herewith: Mallinella marikaban n. sp. is a member of the hilaris-group and it runs close to M. acanthoclada Dankittipakul, Jocqué & Singtripop, 2012 found in Thailand, but the new species from the Philippines can be distinguished from the latter by its distinct thick and sclerotized embolus with bifurcated tip and a “mouthlike” epigynum with a pair of spherical widely spaced spermatheca. Mallinella tingloy n. sp., on the other hand, belongs to the annulipes-group and runs close to M. calilungae (Barrion & Litsinger, 1992) found in the Philippines, and can be distinguished from the latter with the presence of long and broad embolus with deep longitudinal groove and a sclerotized, lip-like epigynum with widely-spaced longitudinal spermatheca with globular tip.

Authors: Alsaoud Nisreen , N Alsaoud
Published: May 2024

Three plant extracts - Thymus vulgaris, Schinus molle, and Melia azedarach - were tested against adult rice weevils at 25, 50, and 100% concentrations. All extracts caused significant mortality, reaching 100% with 50-100% solutions after one day. Extracts also reduced grain weight loss, damage, and adult emergence. S. molle was effective at 25% concentration (30-44% reduction), with higher efficacy at 100% (98% reduction). M. azedarach showed similar trends (62-69% at 25%, 100% at 100%). T. vulgaris was the most effective, achieving 69-73% reduction at 25% and 100% at all levels. These results suggest significant potential for these plant extracts in eco-friendly rice weevil control programs.

Risk Behind the Glamour: Lipstick and its Health Impacts
Authors: V Sushmitha
Published: May 2024

Lipstick has been a beloved cosmetic for centuries, enhancing the beauty of women worldwide. Lipstick has long been a symbol of beauty and femininity, but beneath its glamorous facade lies potential health risks that deserve attention. This mini review aims to provide a comphrensive overview of the health impacts associated with lipstick use, shedding light on the potential dangers of certain ingredients and the need for consumer awareness. One of the primary concerns surrounding lipstick is the presence of heavy metals. Studies have shown that many lipsticks contain trace amounts of lead, cadmium, and other heavy metals, which can be absorbed through the skin and potentially harm the body overtime. These metals have been linked to various health issues, including reproductive problems and neurotoxicity. Furthermore, the prolonged use of lipstick can lead to unintentional ingestion of harmful metals, posing additional risks. In addition to heavy metals, certain lipsticks may contain parbens, a type of preservative commonly used in cosmetics. Parabens have been associated with hormonal disruption and have raised concerns about their potential links to breast cancer. While the evidence is not conclusive, the presence of parabens in lipsticks warrants further investigation and caution use. However, it’s not all doom and gloom. Many reputable cosmetic brands are taking steps to prioritize safety and offer lipstick options that are free from heavy metals and harmful chemicals. These brands employ rigorous testing and adhere to stricter regulations to ensure the safety of their products. Consumers can make more informed choices by opting for lipstick brands that prioritize safety and transparency in their ingredients lists. In conclusion, while lipstick may enhance our appearance and boost confidence, it’s crucial to be aware of the potential health impacts associated with its use. The presence of heavy metals and potentially harmful ingredients should not be overlooked. By staying informed, choosing safer lipstick options, and advocating for stricter regulations, we can enjoy the glamour of lipstick while minimizing potential health risks and additionally, it provides a comprehensive guide to natural home remedies that can help prevent these side effects. By understanding the potential risks, we can make informed choices about our beauty routines, maintaining healthy, beautiful lips while embracing the love for lipstick.

Authors: G Menge
Published: May 2024

Staphylococcus aureus plays its most significant animal pathogenic role as cause of intra mammary infections in cattle and small ruminants leading to considerable economic losses in cattle farming. A cross sectional study was conducted from February to June 2019 in Adama and Modjo town, to isolate and identify S. aureus and their susceptible to different antimicrobials. Out of a total of 160 samples examined,20.6 % (33) were positive for S. aureus. Of this, 13/86 (15.1%), 20/74(27%) were positive for S. aureus atModjo and Adama, respectively. All 33 isolates were tested for antimicrobial resistance with 12 selected antibiotics. The isolates were highly susceptible to gentamycin (100%), streptomycin 24(72.7%), ciprofloxacin21 (63.6)), and kanamycine20 (60.6%), however, they were highly resistant to methicillin 31(93.9%), penicillin G 30(90.9%), tetracycline 21 (63.6%) and erythromycin (60.6%) respectively. Out of the resistance S. aureus isolates, 31 (93.9%) were developed multidrug resistant against 8 antibiotics. The S. aureus isolates from the dairy farms in the study area were multi drug resistant. Hence, public awareness about good management in dairy farms and milk handling practices, rational use of drugs and periodic assessment of drug sensitivity test should be done to prevent the current global issue which is antimicrobial resistance.
Nutritional and Health Benefits of Microorganisms for Sustainable Food and Medicine
Authors: S Upadhyaya
Published: May 2024

The term ‘single cell protein’ was coined in 1968 at a meeting held at the Massachusetts Institute of Technology (MIT) to replace the less aesthetic ‘microbial protein’ and ‘petroprotein’ which were the terms originally used. Use of microbes as a food source may appear to be unacceptable to some people but the idea of consumption of microbes as food for man and animals is certainly innovative to solve the global food problem. Single cell protein (SCP) has many applications in food and feed industries The microorganisms which can be used as SCP include a variety of bacteria, marine microalgae, Dried cells of bacteria, algae, yeast, and fungi, which are rich in proteins and could be used as dietary supplements, are called Single Cell Proteins (SCP). The use of microbial protein as food has several advantages over conventional proteins. Microbial proteins are healthy source of vitamins, carotenes and carbohydrates. The concept of probiotics is the colonization of beneficial bacteria in the intestinal tract, promoting efficient functioning of digestion, helping prevent digestive upsets, and stimulating and maintaining the natural immunity of the body. Probiotic bacteria are normal inhabitants of the intestines and are normally found in the healthy gut of all humans. Probiotics have been in use for as long as people have consumed fermented milks, but their association with health benefits dates only from the turn of the century when Metchnikoff drew attention to the adverse effects of the gut microflora on the host and suggested that ingestion of fermented milks ameliorated this so-called autointoxication. Supplementation with probiotics, prebiotics and synbiotics has shown promising results against various enteric pathogens due to their ability to compete with pathogenic microbiota for adhesion sites, to alienate pathogens or to stimulate, modulate and regulate the host's immune response. Hence, this review aims to study the nutritional and health benefits of microorganisms for sustainable food and medicine.

Authors: Peralta Eva , Ots María José
Published: May 2024

El desarrollo de la agricultura hace ca. 2500 años promovió cambios demográficos, económicos, sociales y culturales en el centro de Mendoza. Con el propósito de contribuir al estudio de estos procesos, en este trabajo exploramos las tendencias en la dieta y la movilidad en el Valle de Uco a partir del estudio de la colección bioarqueológica del sitio Agua Amarga conservada en el Museo de Historia Natural de San Rafael (Mendoza). Para sortear las dificultades subyacentes a las condiciones del rescate y a la pobre preservación de las muestras, integramos múltiples líneas de evidencia que incluyen la reconstrucción cronológica, el contexto funerario, y el análisis bioarqueológico y de isótopos estables (δ13Ccol, δ15N, δ13Capa y δ18O). Estas líneas se suman a los estudios arqueológicos previos del sitio. Con respecto a las tendencias que señalan un alto consumo de maíz a partir de 1100 años AP que decae hacia 550 años AP en el norte y centro de Mendoza, la evidencia isotópica obtenida de Agua Amarga se destaca en el contexto regional por mantener un alto consumo antes y durante el período tardío-inca e inicio de la colonia. En cuanto a la movilidad, los valores de δ18O de los individuos se corresponden con un origen local o del Valle de Uco, lo cual se deberá ajustar con un muestreo más completo de aguas en la región.

Published: May 2024

Peru is a country open to the world economy and to national and foreign investments; therefore, economic activities of an industrial, commercial and service nature in general are developed. It also has a wide variety of natural resources, which is why the state has chosen to apply differentiated treatment in the tax field to certain types of business activities by granting certain “benefits” and “incentives”. However, due to a lack of knowledge about tax legislation, they are not used adequately. In this context, the objective was to analyze the level of knowledge of the legislation, tax and its impact on the development of their operations in formal business aquaculture in the ring circumlacustrine of the region in 2021. It was developed under a descriptive correlational design with a sample of 80 circumlacustrine ring aquaculture companies. The results indicated that there is a low level of knowledge about tax legislation on the part of the owners of aquaculture companies, which negatively affects the development of their formal operations in the circumlacustrine ring of the Puno region. As a consequence, it has a negative impact on the formalization of companies since they do not know about the benefits and tax incentives and even less about the tax regimes to which they are subject as taxpayers; therefore, aquaculture companies are in the informality category in a high percentage.
How much do Mexicans pay for regulation in the transportation of oil products?
Authors: Jiménez-Pérez Alan Israel , Ortiz-Arango Francisco
Published: May 2024

The new oil derivatives transportation scheme proposed by the 2013 Mexican Energy Reform allowed new participants to enter the sector. The new legal framework requires fulfilling many requirements and corresponding duties for the transportation of oil products. The Mexican government already has an institution dedicated to measuring the regulatory cost of each federal procedure. This work aims to quantify the regulatory costs associated with the procedures and their compliance to obtain permits for transporting oil products by truck. We use the standard cost method to measure these costs, considering all associated costs. The results showed that two government offices did not adequately measure these costs. They did not consider relevant information on frequency and opportunity costs, resulting in undervaluation and leading to wrong expectations. As a result of this research, we provide a more accurate way of estimating these costs, which brings greater certainty in the budgeting of these projects and, therefore, increases the probability of survival and success.

Authors: Semenova Yuliya
Published: May 2024

This interview delves into the relationship between zinc (Zn) and copper (Cu) in autism spectrum disorder (ASD), featuring insights from Dr. Geir Bjørklund, MD, a Norwegian researcher. Collaborative studies conducted across diverse countries, including China, Slovenia, Romania, Russia, Brazil, and Egypt, consistently reveal altered Zn and Cu levels in individuals with ASD. These findings suggest a potential correlation between elevated Cu levels and increased severity of ASD symptoms. Dr. Bjørklund emphasizes the multifaceted dynamics of metallothioneins (MTs), essential proteins for metal binding and detoxification, and their potential association with Zn deficiency in ASD individuals. The interview illuminates the balance between Zn and Cu within the GABAergic system, implicating these trace elements in synaptic modulation and broader neurobiological functions. Future research directions proposed by Dr. Bjørklund encompass exploring multiple biological mediums for accurate trace element assessment, investigating interactions between different trace elements, and exploring factors influencing trace element levels in various tissues. The significance of Zn supplementation in treating ASD, the implications of MT dysfunction, and the importance of dual monitoring of Cu and Zn during therapy are thoroughly discussed. The conclusion expresses gratitude for Dr. Bjørklund’s invaluable contributions to comprehending the role of Zn and Cu in ASD, highlighting the global relevance of his research and the need for a comprehensive approach to understanding trace element dynamics in this complex neurodevelopmental disorder.
