Authors: Midoen Yurnadi Hanafi , Ilyas Syafruddin , Santoso Putra
Published: June 2024

Context: Doxorubicin is an anticancer drug that can adversely affect the liver. Therefore, seeking medical attention to manage pain and minimize side effects is crucial. Aims: To evaluate the hepatoprotective potential of Vitis gracilis Wall. nanoherbs against doxorubicin-induced hepatotoxicity. Methods: The study included five treatment groups: T0 (negative control), T+ (positive control with doxorubicin alone), TC (doxorubicin + vitamin C at 0.2 mg/kg body weight/day), T125 (doxorubicin + V. gracilis at 125 mg/kg body weight/day), and T150 (doxorubicin + V. gracilis at 150 mg/kg body weight/day). Doxorubicin, administered intraperitoneally at 0.0019 mg/kg body weight once a week for three weeks, induced hepatotoxicity in the T+ group. Results: Serum transaminases were significantly reduced in the T125 and T150 groups, indicative of the hepatoprotective effects of V. gracilis. Immunohistochemical analysis demonstrated the modulation of key markers, with decreased levels of pro-inflammatory tumor necrosis factor-α and increased levels of anti-inflammatory interleukin 10 in the T125 and T150 groups. The activities of oxidative stress markers, including superoxide dismutase and caspase 3, were favorably influenced by V. gracilis nanoherb treatment. Conclusions: These findings suggest that V. gracilis nanoherbs may effectively attenuate doxorubicin-induced hepatotoxicity, evidenced by biochemical and immunohistochemical changes. This study provides a foundation for further exploration of V. gracilis nanoherbs as a potential adjunctive therapy in preventing chemotherapy-associated liver damage.

Published: June 2024

Context: Polycystic ovary syndrome (PCOS) and thyroid are the most common endocrine disorders affecting women of childbearing age, causing anovulation and infertility. There is an increased prevalence of thyroid dysfunction reported among PCOS women. Aims: To evaluate the benefits of acarbose plus myo-inositol therapy on the thyroid profile of PCOS. Methods: An open-labelled, parallel randomised clinical trial on 80 PCOS women based on inclusion and exclusion criteria was performed at the Department of Gynaecology, SRM Medical College Hospital and Research Centre, Kattankulathur. Institutional ethics committee approval and prior informed consent were obtained. The trial was registered in CTRI (No: CTRI/2022/04/041877). Group A (n = 38) received metformin 500 mg TID, and group B (n = 39) received acarbose 50 mg TID along with myoinositol 1000 mg BID. Assessment of metabolic and hormonal profile was done at baseline and at the end of six months. Results: Both groups showed significant reductions in luteinising hormone (p <0.0001), total testosterone (p<0.05), thyroid stimulating hormone (p<0.05), fasting insulin (p<0.05), and homeostatic model assessment for insulin resistance (p<0.0001). The follicle-stimulating hormone was increased only in the metformin group. No significant changes in body mass index, free triiodothyronine, free tetraiodothyronine, and fasting glucose were observed in any group. Both therapies were safe, and no side effects or hypoglycaemia were recorded. Conclusions: In consideration of the beneficial effects of the study, we conclude that the administration of acarbose plus myo-inositol exerts positive effects on the thyroid and other endocrinological profiles in PCOS women.

Authors: Abdul-Wahab Mohammed S. , Ali Al-Saif Abdul-Sattar Jaber
Published: June 2024

In this investigation, a new method for studying the effect of non-Newtonian fluid on the flow and temperature distribution when cooling the turbine disk is presented. The new method is based on the homotopy perturbation method developed with the Chebyshev series. The results of the proposed method were compared with the results obtained using numerical methods in previous literature to ensure the validity of the method, as it showed good agreement. The effect of several physical parameters on flow velocity and temperature diffusion, such as the Reynolds number, cross viscosity parameter, Prandtl number, and power law, was explored. The results obtained using the proposed method were more accurate than other methods used to solve the current problem. Moreover, figures and error tables show the new method's efficacy and efficiency.
Main Primitive and Cryptography Tools for Authentication in VANET Environment: Literature Review
Authors: Alzaidi Zahraa Sh. , Yassin Ali A. , Abduljabbar Zaid Ameen
Published: June 2024

Vehicular ad hoc networks (VANETs) provide the potential to improve transportation efficiency by facilitating the sharing of traffic information among vehicles. Acceptance of VANET depends on communication speed and accuracy as well as privacy protection guaranteeing an individual's safety. Vehicle authentication is necessary to ensure message correctness. This necessitates the implementation of an effective privacy-preserving authentication scheme, as well as the need for both secrecy and timebound delivery of messages. Various privacy-preserving authentication schemes have been suggested to guarantee the integrity of messages in communications. However, most of the schemes are not able to solve issues related to computing costs, communication, security, privacy, threats, and vulnerabilities. In this review, we focus on cryptographic strategies that are suggested to accomplish privacy and authentication, such as identity-based, public key cryptography-based, pseudonym-based, and blockchain-based schemes. We provide a thorough analysis of schemes, including their categorizations, advantages, and drawbacks. The study demonstrates that the majority of current authentication techniques necessitate trusted authorities that lack transparency in their operations. Additionally, authentication process incurs substantial computational and communication overhead, leading to a considerable impact on the timely delivery of messages. More efforts are required to enhance the development of efficient authentication schemes in VANETs.

Authors: Merzoq Mohannad A. , Al-Mukh Jenan M.
Published: June 2024

In the present study, we propose a physical model to study spin transport through DNA system and provide apparent physical mechanism for spin dependent phenomenon. The system considered in our work is DNA bases guanine-cytosine coupled to two ferromagnetic leads (FM-(G/C)10-FM) in parallel and anti-parallel configuration case, throughout magnetic quantum contacts. Our treatment is based on the tight binding model to derive obvious formula for the transmission spectrum which is employed to investigate the spin dependent current-bias voltage characteristics and the temperature - Conductance dependence. Our calculations of for strong, weak and without backbone regimes. Various factors are involved in our -study. These are the electrical contacts between DNA molecules and electrodes, the structure of DNA molecule and the environment around DNA molecule. The system spin dependent factors, that are investigated extensively in our study include the spin dependent coupling between subsystems, the quantum contacts between active region and electrodes, majority and minority electrons spin in the ferromagnetic leads as well as externally applied bias voltage. Variation of these factors can enhanced or suppressed spin transport through (G/C)10 molecule. The transmission spectrum calculations conform that the spin transport throughout (G/C)10 originates by a coherent tunneling process between neighboring bases through the overlapping of the LUMO orbitals of the bases. Our results showed that the spin-polarized transport that can be effectively regulated by the type of regime as well as the spin configuration in the leads which can exhibit efficient spin filtering and spin switching by employing the spin blockade phenomenon
Red pepper extract as eco-friendly corrosion inhibitor for Carbon steel N80 in 1 M HCl: Electrochemical and surface morphological studies
Authors: Aksh Ali Khabar , Abdul Nabi Adnan Sultan
Published: June 2024

Four different concentrations of a plant inhibitor (dry red pepper) were created to investigate its effectiveness in preventing corrosion of a N80 carbon steel alloy used in petroleum pipe manufacturing. This was done in a 1M HCl acidic solution at various temperatures using electrochemical techniques and surface analysis. The inhibitor was discovered to be effective and efficient. As inhibitor concentrations rise, inhibition also increases because the protective layer becomes thicker. At a concentration of 200 ppm at a temperature of 298 K, the inhibition efficiency reached 92.69%. Corrosion rate decreases in the presence of the plant inhibitor. Despite the presence of the plant inhibitor, the corrosion rate in the acidic media (HCl 1M) was 15.58 mpy lower than when the inhibitor was absent. It reached 1.138 when it was. This is because of the reduction in the current density of Icorr. The polarisation results showed that the addition of the inhibitor reduced the corrosion current density of the steel. The Carbon N80 corrosion rate ranges from 34.22 µA/cm2 for the sample without inhibitor to 2.5 µA/cm2 for the sample including 200 ppm of inhibitor (C). The polarisation curves and electrochemical investigations suggest that the corrosion inhibitor exhibits both anodic and cathodic inhibition processes, indicating a mixed kind of inhibition. FT-IR technology analysed the inhibitor's chemical composition and revealed the presence of functional groups and heteroatoms. SEM was utilised to locate the inhibitor layer on the carbon steel alloy surface, which serves to prevent corrosion

Characteristics of sediments and regolith alterations in the Plio-Pleistocene succession, coastal cliff sections, St Vincent Basin, South Australia
Authors: May Richard , Milnes Anthony
Published: June 2024

Syn- and post-depositional alterations are distinguished in a detailed lithological and mineralogical study of the largely unconsolidated Plio-Pleistocene non-marine succession in coastal cliff sections in the St Vincent Basin south of Adelaide. At its base, the sequence interfingers with Late Pliocene estuarine marine sediments in places but mostly unconformably overlies older Cenozoic marine sediments or Neproterozoic bedrock. The fluvial and alluvial siliclastics have bioturbation, blocky-prismatic macro-peds and subtle Fe-mottling indicators of hiatuses in deposition, and imprints of soil and shallow groundwater environments. A relative abundance of kaolinite, illite and randomly interstratified illite-smectite reflects both sediment source and conditions in the local depositional environment. A thick deposit of aeolian calcareous silt with associated pedogenic calcretes blankets the succession. Conspicuous bleached Fe mega-mottled intervals and zones of alunite-halloysite within the sequence record post-depositional, groundwater-related alterations in regolith environments. These formed during incision and erosion of the sedimentary fill in the basin in response to regional falls in base level. Each marks a different time and specific geomorphic environment according to the chemistry of the discharge of local groundwaters from aquifers that were intersected by incision and scarp retreat.

The subtribe Pronophilina Reuter, 1896 is a group of Papilionoidea that is particularly useful for assessing biodiversity and human-made disturbance, especially in cloud forests. This is because of their high diversity, abundance, distribution patterns, ecological fidelity, and usefulness in formulating conservation policies. A rapid assessment (RAP) was conducted on the Pronophilina in two locations in the upper montane area of Manu National Park, southeastern Peru. The assessment included an evaluation of species richness, faunal composition, similarity, and community structure of Lepidoptera in the area. The two locations were only 30 km apart but in different elevations, ranging from 2800 to 3200 m above sea level. The study recorded a total of 1941 specimens of 45 species, with 18 species (40%) belonging to the genus Pedaliodes Butler, 1867, and as many as 1356 individuals (70%) were found in this genus. Some local species were found to be restricted to very narrow elevation ranges at the forest-puna grassland ecotone. The community structure showed good adjustment with the RAD log-normal model in Trocha Unión and with the Zipf-Mandelbrot model in Qurqurpampa, indicating that the sample obtained is representative of well-preserved uppermost cloud forests. The Sørensen similarity index was relatively low, despite the short distance between the two sites and no apparent geographic isolation. Sampling by “Van Someren-Rydon” traps was confirmed as a very effective method for studying

Published: June 2024

A survey for the diversity of Rhopalocera at the Mizoram University (MZU) campus was carried out in selected areas with different habitat types. Pollard walks sampling method was adopted, and 16 randomly selected permanent line transects were established in three different sites. The length of the studied transacts was 500 m and the breadth was a region covered by visual observation on both sides from the point of observation along the length. Survey was carried out during September to November 2016 and from February to May 2017. A total of 3,618 individuals of 78 species of these insects belonging to six families were recorded. Maximum number of species recorded belonged to the family Nymphalidae while the family Riodinidae is represented by one species only. Three rare species namely, Parthenos sylvia (Cramer, 1775), Elymnias patna (Westwood, 1851), and Tanaecia lepidea (Butler, 1868) were also recorded. Another consequential aspect in this study is the record of Euploea midamus (Linnaeus, 1758), Castalius rosimon (Fabricius, 1775), Jamides allectus (Grose-Smith, 1894), Euploea mulciber (Cramer, [1777]), and Polytremis discreta (Elwes & Edwards, 1897), which are categorized into different conservation schedules of the Indian Wildlife (Protection) Act of 1972 with amendment made in 2022. Nymphalidae is the most diverse (H = 3.295) and dominant species (D = 22.727) while evenness is highest for the family Pieridae (E = 0.973) and diversity, dominance, and evenness (H = 1.818, D = 5.646, E = 0.826) is least for the family Lycaenidae. This study manifest that the modified habitats are also important repository for biodiversity which also need attention for conservation
Los estados inmaduros y el ciclo de vida de una Megalopyge Hübner, [1820] causante de dermatitis en la ciudad de Córdoba, Argentina (Lepidoptera: Megalopygidae)
Authors: Acosta Pablo Alejandro , Zapata Adriana Inés
Published: June 2024

En las últimas décadas en Argentina se han incrementado notablemente los reportes de casos de erucismo, con algunos brotes de importancia epidemiológica. En diciembre de 2019, un vecino de la ciudad de Córdoba fue afectado por el contacto con orugas de una especie de Megalopyge Hübner, [1820] que se encontraban en un arbusto del arbolado urbano. Considerando la escasa información disponible sobre la familia en esta región del país y el riesgo sanitario potencial que podrían representar estas orugas, se propuso determinar la especie, describir su ciclo biológico y los estados inmaduros, y evaluar la potencialidad de utilización de especies hospedadoras alternativas. Los adultos y los estados inmaduros se asemejan más a los descriptos bajo el nombre de Megalopyge undulata vulpina Berg, 1882 que a cualquier otra especie del género. Sin embargo, algunas diferencias morfológicas y cromáticas conducen a proponer que se tratase de dos taxones afines pero diferentes. A la latitud de Córdoba la especie se comporta como bivoltina, con un tiempo promedio de embriogénesis de 6 días y 58 de desarrollo larval en la segunda generación. El tiempo de permanencia dentro del capullo fue muy variable. El escaso éxito en el intento de alimentar a las larvas con hospedadores alternativos indicaría que la especie no representaría, por el momento, un problema sanitario urbano emergente.

Authors: Vrenozi Blerina , Toshova Teodora B.
Published: June 2024

Theresimima ampellophaga (Bayle-Barelle, 1809) (Lepidoptera: Zygaenidae, Procridinae), occurs as a partly harmful species in vineyards in the Mediterranean region, where it has the proper conditions for larvae development, including the host plants and hilly relief. In 2017, has been registered as a new country record in the vineyards of the western lowland in Albania on the base of a large-scale study using traps baited with the synthetic sex pheromone of Th. ampellophaga females or the sex attractant EFETOV-2. The further field works in 2018 and 2019 using sex pheromone traps aimed to establish in new localities in Albania and determine the northern distribution limit of Th. ampellophaga in this country. In 2019, low numbers males were captured in three vineyards in Apolloni, Radostinë (district of Fier) and Dukat i Ri (district of Vlorë), southern Albania in the first half of July, all from the first generation. As a preliminary result, the northern distribution limit in Albania is reported.
