Humankind is witnessing a gradual increase in cancer incidence, emphasizing the importance of early diagnosis and treatment, and follow-up clinical protocols. Oral or mouth cancer, categorized under head and neck cancers, requires effective screening for timely detection. This study proposes a framework, OralNet, for oral cancer detection using histopathology images. The research encompasses four stages: (i) Image collection and preprocessing, gathering and preparing histopathology images for analysis; (ii) feature extraction using deep and handcrafted scheme, extracting relevant features from images using deep learning techniques and traditional methods; (iii) feature reduction artificial hummingbird algorithm (AHA) and concatenation: Reducing feature dimensionality using AHA and concatenating them serially and (iv) binary classification and performance validation with three-fold cross-validation: Classifying images as healthy or oral squamous cell carcinoma and evaluating the framework’s performance using three-fold cross-validation. The current study examined whole slide biopsy images at 100× and 400× magnifications. To establish OralNet’s validity, 3000 cropped and resized images were reviewed, comprising 1500 healthy and 1500 oral squamous cell carcinoma images. Experimental results using OralNet achieved an oral cancer detection accuracy exceeding 99.5%. These findings confirm the clinical significance of the proposed technique in detecting oral cancer presence in histology slides.

SARS-CoV-2 (COVID-19) spreads and develops quickly worldwide as a new global crisis which has left deep socio-economic damage and massive human mortality. This virus accounts for the ongoing outbreak and forces an urgent need to improve antiviral therapeutics and targeted diagnosing tools. Researchers have been working to find a new drug to combat the virus since the outbreak started in late 2019, but there are currently no successful drugs to control the SARS-CoV-2, which makes the situation riskier. Very recently, new variant of SARS-CoV-2 is identified in many countries which make the situation very critical. No successful treatment has yet been shown although enormous international commitment to combat this pandemic and the start of different clinical trials. Nanomedicine has outstanding potential to solve several specific health issues, like viruses, which are regarded a significant medical issue. In this review, we presented an up-to-date drug design strategy against SARS-CoV-2, including the development of novel drugs and repurposed product potentials were useful, and successful drugs discovery is a constant requirement. The use of nanomaterials in treatment against SARS-CoV-2 and their use as carriers for the transport of the most frequently used antiviral therapeutics are discussed systematically here. We also addressed the possibilities of practical applications of nanoparticles to give the status of COVID-19 antiviral systems.

Hydrogen (H2) is one of the most promising renewable energy sources, anaerobic bacterial H2 fermentation is considered as one of the most environmentally sustainable alternatives to meet the potential fossil fuel demand. Bio-H2 is the cleanest and most effective source of energy provided by the dark fermentation utilizing organic substrates and different wastewaters. In this study, the bio-H2 production was achieved by using the bacteria Acinetobacter junii-AH4. Further, optimization was carried out at different pH (5.0–8.0) in the presence of wastewaters as substrates (Rice mill wastewater (RMWW), Food wastewater (FWW) and Sugar wastewater (SWW). In this way, the optimized experiments excelled with the maximum cumulative H2 production of 566.44 ± 3.5 mL/L (100% FWW at pH 7.5) in the presence of Acinetobacter junii-AH4. To achieve this, a bioreactor (3 L) was employed for the effective production of H2 and Acinetobacter junii-AH4 has shown the highest cumulative H2 of 613.2 ± 3.0 mL/L, HPR of 8.5 ± 0.4 mL/L/h, HY of 1.8 ± 0.09 mol H2/mol glucose. Altogether, the present study showed a COD removal efficiency of 79.9 ± 3.5% by utilizing 100% food wastewater at pH 7.5. The modeled data established a batch fermentation system for sustainable H2 production. This study has aided to achieve an ecofriendly approach using specific wastewaters for the production of bio-H2.

Successful captive broodstock development of clupeid fish, hilsa, is one of the major challenges for the artificial propagation of this economically valued fish. The present study provides novel insights into the pond-reared captive broodstock development of hilsa using artificial feed. In the present study, wild collected hilsa fry (weight 1.35 ± 0.13 g, length 53.84 ± 0.95 mm) were reared in grow-out ponds for 6 months followed by maintaining them as broodstock in other ponds using formulated feed in both cases. After 6 months of pond rearing, the average body weight and length of fish were 66.76 ± 4.53 g and 184.75 ± 3.65 mm, respectively. In broodstock ponds, hilsa subadults fed with formulated feed (crude protein 41.06%) ensured significant advancement in ovarian maturity with gonado somatic index of 9.09%, enhanced secondary yolk stage oocytes of 91.66% and enlargement of oocyte diameters up to 570 μm. The broodstock reached somatic growth such as average body weight and average body length of 383.80 ± 27.38 g and 339.33 ± 9.68 mm, respectively, with a condition factor of 1.06 ± 0.15. Gut content analysis revealed the better acceptability of the artificial feed. Lipid profiling of muscle and ovary during gonadal maturation revealed mobilization of fat from muscle to ovary and selective retention of some fatty acids (i.e., C14:0, C18:0, C20:5, C22:6 and C20:4) in the ovary, which might help in gonadal maturation. STATEMENT OF SIGNIFICANCE: Successful rearing of wild-caught hilsa juvenile in captive condition using formulated feed showed its potential as aquaculture species in low saline conditions. Advance stage of maturation in low saline captive conditions showed the possibility for induced breeding of hilsa, a high priced anadromous fish. Mobilization of fat from muscle to ovary and selective retention of some fatty acids in the ovary showed the scope of dietary manipulation for broodstock development of hilsa.

Early childhood caries (ECC), a severe form of caries due to cross-kingdom interaction of Candida albicans and Streptococcus mutans, is a serious childhood dental disease that affects majority of the children with poor background. The present study investigated the anti-infective potential of thymol against C. albicans and S. mutans dual species for the management of ECC. Thymol, a plant derivative of the monoterpene group, has been well known for its numerous biological activities. Thymol at 300 μg/ml concentration completely arrested growth and proliferation of dual species of C. albicans and S. mutans. Rapid killing efficacy of pathogens, within a span of 2 min, was observed in the time kill assay. In addition, at sub-inhibitory concentrations, thymol effectively diminished the biofilm formation and virulence of both C. albicans and S. mutans such as yeast-to-hyphal transition, hyphal-to-yeast transition, filamentation, and acidogenicity and acidurity, respectively, in single and dual species state. qPCR analysis was consistent with virulence assays. Also, through the invertebrate model system Galleria mellonella, in vivo toxicity and efficacy of the phytocompound was assessed, and it was found that no significant toxic effect was observed. Moreover, thymol was found to be proficient in diminishing the infection under single and dual state in in vivo condition. Overall, the results from the present study illustrate the anti-infective potential of thymol against the ECC-causing dual species, C. albicans and S. mutans, and the applicability of thymol in medicated dentifrice formulation.

The growing threat of pathogenic microbes has increased the rate of morbidity and mortality among the human population. Centres for Disease Control has announced that the world is entering the post antibiotic era, which will increase the death rate by bacterial infections instead of cancer and other fatal diseases. Nonetheless, the emergence of multidrug resistant strains of bacteria has led to finding novel strategies to prevent bacterial growth on abiotic and biotic surfaces. Therefore, nanomaterials are growing as a potential strategy to replace conventional antimicrobial therapy. In recent times, bacterial pathogens have been known to colonize on medical devices, implants, tooth filings, lenses, fabrics, metallic and non-metallic surfaces. Important significance organic and inorganic nanomaterials include silver (Ag), copper (Cu), zinc oxide (ZnO) and gold (Au), titanium (Ti), selenium (Se), iron (Fe) as well as polymer materials have been highlighted as potential coating materials for preventing the growth and attachment of bacteria. Nanoparticles (NPs) have a large surface area to volume ratio and generate reactive oxygen species (ROS) leading to the damage of the bacterial cell walls. The present review has focused on the important role of nanoparticles as a coating material to create antibacterial surfaces for a prolonged time and efficiency.

The development of effective and reliable drugs in the fight against malaria and cancer represents a crucial challenge in modern parasitology. The present investigation focuses on a simple and novel strategy for the biological synthesis of silver nanoparticles (Ag NPs) using β-caryophyllene isolated from the leaf extract of Murraya koenigii, as reducing and stabilizing agent. UV–visible spectroscopy of the Ag NPs in aqueous suspension revealed strong surface plasmon resonance at 420 nm. Fourier transform infrared spectrum showed the various characteristic peaks of reducing functional groups. X-ray diffraction indicated 2 theta values confirming the Bragg’s refraction index of Ag NPs. Scanning electron microscopy showed the nanoparticle spherical shapes while transmission electron microscopy showed nanoparticle sizes ranging from 5 to 100 nm, with an average size of 29.42 nm. Ag NPs exhibited promising activity on chloroquine-sensitive Plasmodium falciparum (3D7) (IC50: 2.34 ± 0.07 µg/ml), as well as significant cytotoxic activity on lung cancer cells (IC50: 9.39 ± 0.08 µg/ml). Overall, β-caryophyllene synthesized Ag NPs could be further considered as a promising source for the development of cost effective and safer alternative drugs to treat malaria and cancer.

The bio-reduction of chloroauric acid (HAuCl4) into well dispersed gold nanoparticles (GNPs) was achieved using the Albizia amara Roxb. plant extract. The formation of GNPs was confirmed by a change of color from yellowish green to purple with a characteristic peak at 543 nm. Further, the characterization of the synthesized GNPs showed their crystalline nature, functional groups, size and dispersed shapes, purity and Bragg’s reflections of face centered cubic structure. The zeta potential analysis revealed that A. amara GNPs did not aggregate and were quite stable which is in agreement with the constancy found during the dynamic light scattering measurements. During the DPPH assay, the GNPs and leaf aqueous extract showed the scavenging activity of 74 and 65 %, respectively and their in vitro IC50 inhibitory values (µg ml−1) were; 47.77 (HeLa) and 72.28 (Vero). The Gram positive, Staphylococcus aureus (MTCC 96) was found to be more sensitive to GNPs (16 mm) than the leaf aqueous extract (12 mm). In view of the recorded free radical, cytotoxic and antibacterial effects, the GNPs of A. amara could be a potential source for further research towards therapeutic development.

Entomopathogenic nematodes (EPNs) in the families Steinernematidae and Heterorhabditidae are effective biocontrol agents against a number of important soil insect pests and are safe to vertebrates, plants and other non-target organisms with no negative effects on the environment. They are associated with mutualistic bacteria in the genus Xenorhabdus for Steinernematidae and Photorhabdus for Heterorhabditidae and are often referred to as the nematode/bacterium complex. The natural habitat of EPNs is the soil where the third-stage infective juveniles (IJs), the only free-living stage, can infect an array of insect hosts. However, the survival of the IJs is affected by various abiotic (i.e., temperature, moisture, soil texture, soil salinity, UV light, oxygen, and pH) and biotic (i.e., natural enemies, omnivores, scavengers, competitors, and plants) factors in the soil. In this review, we summarize the impact of the biotic factors, especially natural enemies, omnivores, scavengers, and competitors against EPNs and conclude that the major predators of the IJs appear to be nematophagous fungi, mites, and collembolans. Omnivores and scavengers, particularly, mites, collembolans, ants and birds, feeding on EPN-killed insects appear to be the major mortality factors on the developing nematodes especially of insects that are 2 days or less post infection. In addition, we discuss the defense mechanisms of EPN IJs against nematophagous fungi, and the protection of the nematode-killed insects by production of the scavenger deterrent factor produced by the mutualistic bacteria against omnivores and scavengers. By understanding the interactions between EPNs and their antagonists we can improve and increase the successful use of EPNs in biological control programs.

Parasitic infestations are frequently reported in brackishwater fish. Hence, prevention and control strategy is paramount for successful brackishwater aquaculture. Emamectin benzoate (EMB) is found to be an effective in-feed treatment for controlling several ecto-parasites in fish. The objective of this study was to understand the biosafety, withdrawal and efficacy of EMB for use in brackishwater reared Asian Seabass (Lates calcarifer) under tropical climate. Biosafety was evaluated at doses of 0, 50, 250 and 500 μg kg−1 of fish body weight (BW) day−1 for 21 days. EMB was administered per os through coated pellet feed. Gross, haematological and histopathological observations were made and found that there were no biologically significant adverse changes between control and treated groups. Withdrawal period was estimated with similar experiment with same doses but for seven consecutive days. Samples were collected on 0th, 7th, 14th, 21st and 28th day of post-medication for QTRAP 4000 LC-MS/MS analysis. The data showed that the level of EMB in whole fish treated with 50, 250 and 500 μg kg−1 of fish BW day−1 were 21.0 ± 0.0, 142.4 ± 0.1 and 209.7 ± 0.1 parts per billion (ppb) on 0th day of withdrawal, respectively. These values were found drastically decreased on 7th day of withdrawal and reached undetectable level by 28th day. For assessing the environmental safety, acute immobilization test was conducted using 24 h old daphnid. The EC50 and LC50 values in daphnids were 107 and 160 times higher than the the treatment dose, respectively. Efficacy was tested with the therapeutic dose on Asian Seabass fingerlings infested with naturally sea louse (Caligus minimus). Medicated pellet feed was fed at 4% BW day−1 divided equally between three feedings. Efficacy trial showed that there was significant improvement in survival (92.0 ± 2.3%; P

A 75-day 2 × 3 factorial experiment was conducted to evaluate the effect of two levels of dietary protein (32 and 40%) and two different carbon sources (rice flour–R and molasses-M), and without carbohydrate (control–C) in black tiger shrimp Penaeus monodon juveniles (3.37 ± 0.04 g) at 100 nos. m−3 in 100 L fibre reinforced plastic tanks. Biofloc volume and total suspended solid were higher in molasses added groups (32 + M and 40 + M) followed by rice flour (32 + R and 40 + R) and controls (32C and 40C). Molasses and rice flour addition significantly reduced (P

Various application methods for the entomopathogenic nematode Heterorhabditis bacteriophora were evaluated under laboratory and field conditions. Four different methods of applying the infective juveniles (IJs) of the nematode to soil were assessed including (1) insect cadavers (referred to as nematode- infected cadavers), (2) subsurface injection, (3) spraying, and (4) drip irrigation. In the laboratory experiment, except for the control with no nematodes, all treatments showed more than 95% insect mortality of the bait insect (Galleria mellonella) with no significant differences among treatments. The same experimental setup was conducted with the introduction of mites, Sancassania polyphyllae (Acari: Acaridae), which are natural enemies of entomopathogenic nematodes. The treatment groups with mites and the control group without mites showed more than 87% insect mortality and no significant differences were observed. The nematode- infected cadaver application method was further evaluated by using cadavers of different ages containing H. bacteriophora IJs in the presence of mites. Larval mortality of the bait insect was significantly lower when 3- or 6- dayold nematode- insect cadavers were used in the presence of mites. Different application methods were also tested in a corn field. No significant differences were observed among the application methods. Our results indicate that the different application methods had no significant effect on larval mortality, but the presence of mites had a negative effect on the cadaver application when the cadavers were 3 days old but had no significant effect when the cadavers were 6 and 9 days old.

The Lantana camara Linn root extract derived gold nanoparticles (Au NPs) were characterized by Ultraviolet-Visible spectroscopy, X-ray diffraction, fourier transform-infrared, high resolution transmission electron microscopy, selected area electron diffraction pattern and energy dispersive X-ray analyses. In DPPH assay, the inhibitory concentration (IC50) of Au NPs and gallic acid was 24.17 and 5.39 μg/ml, whereas, for cytotoxicity assay, the IC50 of Au NPs was 17.72 and 32.98 μg/ml on MBA-MB-231 and Vero cells, respectively. Thus, the Au NPs possess significant in vitro antioxidant and cytotoxic properties which could be considered as potential alternate for the development of anticancer drug in future.

Pachiappan, Perumal/0000-0002-6496-1607 WOS: 000395227900006 PubMed: 27908637 The symbiotic bacteria, Photorhabdus and Xenorhabdus associated with entomopathogenic nematodes (EPNs) in the genera Heterorhabditis and Steinernema, respectively, produce a compound(s) called the Scavenging Deterrent Factor (SDF). SDF deters a number of terrestrial insect scavengers and predators and one bird species from feeding on host insects killed by the nematode-bacterium complex but has not been tested against aquatic vertebrates. Moreover, the Heterorhabditis-Photorhabdus association is believed to have evolved in an aquatic environment. Accordingly, we hypothesized that SDF will deter fish from feeding on nematode-killed insects and tested the responses of three omnivorous fresh water fish species, Devario aequipinnatus, Alburnoides bipunctatus, and Squalius pursakensis, to SDF in the laboratory. When the fish were exposed to Galleria mellonella larvae killed by the Heterorhabditis- or Steinernema-bacterium complex at 2 or 4 days post-infection, all three fish species made several attempts to consume the cadavers but subsequently rejected them. However, all fish species consumed freeze killed control larvae. In a choice test, when D. aequipinnatus or A. bipunctatus were offered a pair of nematode-killed larvae, both fish species rejected these cadavers; when offered a nematode-killed larva and a freeze-killed larva, both fish species consumed the freeze-killed larva but not the nematode-killed one. In further tests with D. aequipinnatus, there was no significant difference in the number of 2-day-old Bacillus thuringiensis subsp. kurstaki-killed (Btk) larvae consumed compared to freeze-killed larvae, but significantly fewer 4-day-old Btk-killed larvae were consumed compared to freeze-killed larvae. When D. aequipinnatus was fed G. mellonella larvae killed by the symbiotic bacteria, the fish rejected the cadavers. When given freeze-killed or nematode-killed mosquito (Aedes aegypti) larvae, the fish consumed significantly more of the former larvae (99%) compared to the latter (55%). When D. aequipinnatus was placed in a symbiotic cell-free supernatant for 18 h, a significant reduction in consumption of freeze killed larvae compared to cell-free Btk or control broth supernatant was observed. We showed that SDF protects the nematode-killed insects from being consumed by omnivorous fishes and suggests that they will have minimal effects on recycling of EPNs in the aquatic environment.

Our study describes basic ecological properties of Steinernema siamkayai Tiruchirappalli strain from India. The effect of temperature on nematode infectivity and development, laboratory host range and foraging behaviour were determined. The data showed that S. siamkayai is a warm-adapted nematode species with larval mortality observed between 15°C and 37.5°C and nematode reproduction occurring between 20°C and 35°C. All insect species used in this study were susceptible to S. siamkayai under laboratory conditions. Sixty infective juveniles (IJs) per insect were used and the lepidopterans, Galleria mellonella (100%) and Spodoptera exigua (85%), were the most susceptible species followed by the dipteran, Ceratitis capitata (60%), and lepidopteran, Cydia splendana (55%), and the coleopteran, Tenebrio molitor (45%), whereas the coleopteran, Curculio elephas (25%), was the least susceptible species. S. siamkayai infective juveniles (IJs) stood on their tails and jumped and could also attach to a mobile host at a rate of 27 IJs larvae−1 out of 1000 IJs in 10 min. Larval mortality of G. mellonella by S. siamkayai on different substrates (sand, filter paper, filter paper sprinkled with sand) was 100% on all substrates. Number of IJs out of 100 IJs that penetrated into a G. mellonella host at different soil depths was the highest at the surface (44 IJs larva−1) and the lowest at 5 cm depth (13 IJs larva−1) with no larval mortality observed at 10 cm depth. In addition, the symbiotic bacterium of S. siamkayai was identified as Xenorhabdus stockiae based on genotypic and phenotypic characterisation. Bacterial growth was observed between 15°C and 41°C.

The microhabitat preference of zebrafish, Danio rerio from Karala river was investigated. The availability/ preference of microhabitat variables such as (i) distance from the stream bank (ii) water column depth (iii) mesohabitat (iv) water velocity (v) substratum and (vi) subaquatic vegetal cover were quantified based on underwater observations covering a total of 400 m2 of stream area. Microhabitat selectivity was analyzed by comparing the microhabitat availability in the study site and the microhabitat used by fish. Data availability and microhabitats usage pattern were used for calculating habitat availability/preference of D. rerio. In order to test the microhabitat preference of D. rerio the Principal Component Analysis (PCA) and Canonical Correspondence Analysis (CCA) were applied. In PCA the first three components with higher Eigenvalue accounted for about 98.46% of the total variance. The first component axis alone explained 86.33% of the variance with an Eigenvalue of 5.3 with high loadings (>0.7). CCA revealed a clear separation of the D. rerio along the microhabitat variables. Among the thirty two microhabitat variables, the forward selection procedure was found to be positively significant with eighteen microhabitat variables P

Dengue infection is emerging as a serious public health problem in Tamil Nadu. An enhanced surveillance system can generate information on the epidemiology of the disease, which is essential for planning and development of relevant control/preventive measures against Dengue.A prospective descriptive study was undertaken between January 2011 to December 2011, by testing suspected Dengue patients attending Thanjavur Medical College and Trichy Hospital (TMCH, a major Government referral hospital in Thanjavur District, Tamil Nadu, India) to define the magnitude of Dengue burden, the natural history of this disease in terms of clinical presentation and outcome of the infections in hospitalized Dengue patients. The sera collected from suspected patients were analyzed for Dengue specific IgM and IgG antibodies by IgM antibody capture enzyme linked immunosorbent assay (ELISA) using NIV kit and IgGPanBio Duo Rapid Immunochromatographic Card Test (Brisbane, Australia). The clinical case definition by World Health Organization was adopted to categorize the Dengue cases.The total number of samples screened during the period was 200, out of which 79 (39.5%) were positive for IgM and IgG antibodies and 65 (32%) for IgM antibodies only. By clinical evaluation, Dengue fever was diagnosed in 43 patients, 18 had hemorrhagic manifestations and four patients had progressed to DSS. Though (DSS+DHF) was present in 22 patients, all of them recovered well.In developing countries like India, building of laboratory with advanced capacity for diagnosis and combat-mode ready preparedness for the management of Dengue cases in emergency situation may reduce Dengue-related mortality.

The ethanolic extract of Hypnea muciformis (red algae) was tested for hepatoprotective activity against experimentally induced liver damage by Carbon tetrachloride (CCl4) in male albino rats. The levels of serum enzymatic and biochemical parameters such as serum glutamate oxaloacetate transaminase (SGOT), Serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), lactate dehydrogenase, 5' nucleotidase, bilirubin, creatinine, urea, triglycerides, lipid peroxides and albumin were determined. The CCI4 induced lesions in the liver significant increased the levels of serum marker enzymes SGPT and SGOT, bilirubin, creatinine and decreased urea. The oral treatment with ethanolic extract of H. muciformis exhibited significant hepatoprotective activity by reducing the CCL4 caused changes in the biochemical parameters such as total protein, total bilirubin, total cholesterol, triglycerides, and urea. These parameters were restored towards the normal levels as shown by the enzymatic tests. In addition, H. muciformis significantly decreased the liver weight of CCl4 intoxicated rats. Apparently the H. muciformis extract interfered with the free radical formation, which resulted in hepatoprotective activity. Acute toxicity studies revealed that the LD50 value was more than 3 g/kg body weight. These results clearly indicated that this seaweed contained some active principles in its ethanolic extract which acted as an antidote against the hepatotoxicity induced by CCl4.
