    The species of the genus Thelcticopis Karsch, 1884 from India, Myanmar, Pakistan, and Sri Lanka are reviewed. Stasina nalandica Karsch, 1892 and S. paripes (Karsch, 1879) are re-transferred to the genus Thelcticopis. Thelcticopis ajax Pocock, 1901, T. bicornuta Pocock, 1901, T. birmanica Thorell, 1895 stat. rev., T. hercules Pocock, 1901, T. moolampilliensis Sunil Jose & Sebastian, 2007, T. nalandica (Karsch, 1892) comb. rest., T. paripes (Karsch, 1879) comb. rest., T. picta (Thorell, 1887), T. rufula Pocock, 1901, T. serambiformis Strand, 1907, and T. virescens Pocock, 1901 are diagnosed, redescribed, and/or illustrated based on type and/or freshly collected material, and their current distributional records are mapped. The female of T. virescens is described for the first time. The type locality of Thelcticopis goramensis (Thorell, 1881) is situated in Indonesia, Maluku, not in Malaysia. Thelcticopis bifasciata (Thorell, 1891), and T. fasciata (Thorell, 1897) are proposed as nomina dubia as the holotypes are immature and their identity cannot be fully elucidated. Thelcticopis ancorum Dyal, 1935 and T. telonotata Dyal, 1935 from Lahore, Punjab are considered species incertae sedis, and the subfamily Sparianthinae is most likely not distributed in Pakistan.

    INTRODUCTION: Silver nanoparticles (AgNPs) are effective against almost all kinds of pathogenic organisms. The green synthesis of AgNPs utilizing extracts from medicinal plants is being researched to examine the therapeutic advantages of AgNPs because the chemical production of AgNPs is more toxic. In this study, the stem extract of Ocimum Gratissimum (OG) also known as Karunthulasi or wild basil for green synthesis of AgNPs and evaluating their antiinflammatory and antimicrobial effects.

    MATERIALS AND METHODS: The produced nanoparticles were characterized using UV-visible spectroscopy. The Bovine Serum Assay (BSA) and Egg Albumin (EA) assays were used to assess the anti-inflammatory effects. The protein denaturation of AgNPs was calculated and compared to a standard to determine the anti-inflammatory activity of green synthesized AgNPs. Using varying concentrations of OGmediated AgNPs in Mueller Hinton Agar (MHA), the antimicrobial effects of OG have been investigated against E. coli, S. aureus, and Pseudomonas sp. Additionally, by measuring optical density, the time-kill curve analysis for E. Coli and S. Aureus has been examined from one hour for up to five hours.

    RESULTS: The green synthesized AgNPs were developed successfully using a plant Ocimum gratissimum. The synthesized AgNPs exhibited a maximum absorption peak at 440 nm and SEM analysis revealed that the synthesized AgNPs were spherical and oval. The result findings of the anti-inflammatory activity reveal that AgNPs have great potential when compared to the standard. At the concentration of 50 μg/mL, AgNPs exhibit 76% in BSA assay and 74% in EA assay, where the standard shows 80% inhibition. The antimicrobial activity showed a zone of inhibition around 19mm for E. coli and a 20mm zone of inhibition for S. aureus and Pseudomonas sp., which shows the efficacy of AgNPs. The time-kill assay shows that the optical density of E. coli and S. aureus was reduced to 0.1 after 5 hours of incubation, which shows the potential of green synthesized AgNPs.

    CONCLUSION: OG-mediated AgNPs have both antiinflammatory and antimicrobial effects. Anti-inflammatory effects are better when compared to standard drugs. Antimicrobial effects are better for Gram-negative bacteria.

    The spider genus Glenognatha Simon, 1887 (Tetragnathidae) currently has 34 nominal species distributed in Afrotropical region, Indo-Malaya, Nearctic, Neotropics, Oceania and Palearctic regions (Cabra-García Brescovit 2016; World Spider Catalog 2020). It has one representative in India: Glenognatha dentata (Zhu Wen, 1978) (World Spider Catalog 2020). The genus Pachygnatha Sundevall, 1823 currently comprises 46 nominal species distributed in Africa, Holarctic, South and South-East Asia (World Spider Catalog 2020). Biswas and Roy (2004) recorded this genus in India, while they described Pachygnatha silentvalliensis Biswas Roy, 2004. The species is known from its original verbal description only since the genitalic illustrations were apparently not published along with the description (Biswas Roy 2004), thus leaving its identity obscured. To redescribe and illustrate this species, we examined its type material and found that Biswas and Roy (2004) had misidentified the species and in fact it belongs to Tylorida Simon, 1894. In this paper, we describe a new Glenognatha species from the southern Western Ghats of India, transfer Dyschiriognatha ganeshi Bodkhe, Manthen Tanikawa, 2014 to Glenognatha and synonymise P. silentvalliensis with Tylorida marmorea (Pocock, 1901).

    INTRODUCTION: Selenium nanoparticles (SeNPs) have drawn a lot of interest among researchers because of their distinct impact on antioxidant activity, anti-inflammatory tests, antibacterial activity, and in the treatment of various diseases. A. linearis has shown great findings in biomedical applications because of its physio-chemical compounds such as Aspalathin, orientin, and isoorientin. The increasing demand for eco-friendly and sustainable nanomaterial synthesis has led to the development of green methods utilizing natural resources. The study's main objective is to synthesize green SeNPs using Aspalathus linearis and then test them for cytotoxic, anti-inflammatory, and anti-diabetic properties.

    MATERIALS AND METHODS: A UV-visible spectrophotometer and SEM were used to characterize the green synthesized SeNPs. The anti-inflammatory and anti-diabetic activities of green synthesized SeNPs were measured using the alphaamylase inhibitory & beta-glucosidase enzyme inhibition assay and the egg albumin, bovine serum albumin, and membrane stabilization assays. A test for the mortality of brine shrimp was used to determine the cytotoxic impact of SeNPs.

    RESULTS: A. linearis powder was used for the green synthesis of selenium nanoparticles, which exhibited the highest peak at 440 nm when analyzed using a UV-visible spectrophotometer. The In vitro anti-inflammatory effect of synthesized SeNPs was maximally inhibited by 44-83% in the bovine serum albumin assay 54-79% in the egg albumin assay, and 54-86% in the membrane stabilization assay compared with standard. The inhibition percentage of antidiabetic activity was found to be 50-86% in the alphaamylase assay and 49-85% in the beta-glucosidase assay when compared to standards at various concentrations. Furthermore, the cytotoxicity impact shows that 70% of brine shrimp were alive at the maximum fixation of 80 µg/mL.

    CONCLUSION: The SeNPs showed concentration-dependent anti-inflammatory and anti-diabetic action, and the green synthesized SeNPs demonstrated an excellent antiinflammatory and anti-diabetic agent. The brine shrimp lethality assay confirmed the SeNPs' biocompatible nature even at high concentrations with less toxicity. Hence the study may enhance SeNPs in developing inflammation drugs and can also be utilized in diabetes management.

    INTRODUCTION: The biomedical potential of silver nanoparticles (Ag NPs) synthesized with Zingiber officinale and Ocimum gratissimum herbal formulation was investigated in this study. The study aims to reveal their applications in various biomedical fields. The study evaluates the antioxidant, thrombolytic, and antimicrobial potential of Zingiber officinale and Ocimum gratissimum herbal formulation-mediated Ag NPs.

    MATERIALS AND METHODS: Biogenically synthesized silver nanoparticles (Ag NPs) from an herbal formulation containing Zingiber officinale and Ocimum gratissimum were tested at various concentrations using the DPPH (2,2- diphenyl-1-picrylhydrazyl) assay. The absorbance was measured at 517 nm to quantify DPPH free radicals. With Ag NP concentrations, the H2O2 test exhibited increased activity. This work evaluated the antibacterial activity of Ag NPs mediated by Zingiber officinale and Ocimum gratissimum against Staphylococcus aureus, Streptococcus mutans, Candida albicans, and Enterococcus faecalis.

    RESULTS: The utilization of herbal formulations from Z. officinale and O. gratissimum to synthesize Ag NPs revealed considerable therapeutic effectiveness. At a concentration of 50 μl, the maximal inhibition was 76%, which is comparable in effectiveness to that of standard ascorbic acid. Significant blood clot dissolution was observed during thrombolytic testing at a concentration of 100μg/ml, indicating promising prospects for the treatment of thrombotic disorders. Nanoparticles dose-dependently inhibited E. faecalis, C. albicans, S. aureus, and S. mutans in antibacterial testing. These results show the potential of the nanoparticles as supplementary or alternative treatments to conventional antibiotics, particularly in light of the increasing prevalence of antibiotic resistance.

    CONCLUSION: The further investigation of nanoparticles into their mechanisms and efficacy in therapeutic applications, positioning Zingiber officinale and Ocimum gratissimum formulation-mediated Ag NPs as viable candidates in developing antioxidant, thrombolytic, and antimicrobial treatments.
