Abstract
Vinorelbine, a vinca alkaloid, is an antimitotic drug that inhibits polymerisation process of tubulins to microtubules, and is widely used in cancer chemotherapy. Due to the importance of the structure-activity relationship, in this work the conformational preferences of the vinorelbine molecule were surched by PM3 method. The obtained lowest energy conformer was then optimized at DFT/B3LYP/6-31G(d,p) level of theory and the structural characteristics were determined. Frontier orbital (HOMO, LUMO) and molecular electrostatic potential (MEP) analyses were performed for the optimized structure. The experimental FT-IR, Raman and UV-VIS spectral data of vinorelbine along with the theoretical DFT/B3LYP/6-31G(d,p) calculations were investigated in detail. The vibrational wavenumbers were assigned based on the calculated potential energy distribution (PED) of the vibrational modes. To shed light into the anticancer property of vinorelbine as microtubule destabilizer, the most favourable binding mode and the interaction details between vinorelbine and tubulin were revealed by molecular docking studies of vinorelbine into the α,β-tubulin (PDB IDs: 4O2B; 1SA0; 7CNN) and binding free energies were calculated by the combination of Molecular Mechanics/Generalized Born Surface Area (MMGBSA) and Molecular Mechanics/Poisson-Boltzmann Surface Area (MM-PBSA) methods {MM/PB(GB)SA}. The calculated vinorelbine-7CNN binding free energy, using by MM/PB(GB)SA approach, was found to be the best (-50.39 kcal/mol), and followed by vinorelbine-4O2B (-28.5 kcal/mol) and vinorelbine-1SA0 (-17.59 kcal/mol) systems. Moreover, the interaction of vinorelbine with the cytochrome P450 enzymes (CYP), which are known to help in the metabolism of many drugs in the body, was investigated by docking studies against CYP2D6 and CYP3A4 targets.Communicated by Ramaswamy H.

Abstract
This study characterized novel RNA viruses, parasites of parasites, or hyperparasites identified during transcriptomic analyses of two trematode species, Cryptocotyle lingua and Himasthla elongata, infecting a sea snail, Littorina littorea. According to the viral genome structures and phylogenetic analysis, Cryptolin alternavirus (ClRNAV1), Cryptolin calicivirus (ClRNAV2) and Himastelon rhabdovirus 1 (HeRNAV1) were respectively classified within the families Alternaviridae, Caliciviridae and Rhabdoviridae. They replicate species-specifically in two studied phases of trematode live cycle: intramolluscan parthenogenetic rediae and free-swimming cercariae. ClRNAV1 showed significantly higher expression in C. lingua cercariae relative to rediae. HeRNAV1's similarity to rabies viruses raises questions about its potential effects on the nervous system of H. elongata. This 'trematode rabies' could enable the use of genetically modified viruses for developing new methods to control the spread and intensity of diseases caused by trematodes.

Abstract
Aim: This work aims to synthesize the gold nanoparticles (GNPs) using a dual extract of tulsi and Vinca (T+V-Gold) for breast cancer tumor regression. Methods: The GNPs were synthesized and characterized for their microscopic, spectroscopic and crystalline properties. Further, the GNPs were investigated for in vitro and in vivo studies for the treatment of the 4T1-induced triple-negative breast cancer murine model. Results: The GNPs for 4T1 tumor-challenged mice resulted in delayed tumor development and lower tumor burden, with T+V-Gold demonstrating the highest prevention of tumor spread. The antitumor effect of T+V-Gold is highly significant in the glutathione family antioxidants glutathione S-transferase and glutathione in tumor tissue samples. Conclusion: The bioefficacy and anticancer outcomes of T+V-Gold nanoformulation can be used as therapeutic agents and drug-delivery vehicles.

Abstract
The interactions between habitat fragmentation and other stressors are considered a key knowledge gap. The present study tested the hypotheses that mercury enhances the effects of fragmentation by (1) reducing the cumulative daily movement of organisms, (2) shifting their foraging behavior, and (3) altering the vertical movement of the marsh periwinkle (Littoraria irrorata) in a field experiment. Random walk simulations were used to access how changes in movement affect the search efficiency of organisms in the long term. Eighteen 1.5 m2 plots were constructed in a salt marsh where landscapes characteristics were manipulated to reach three different levels of habitat cover. Daily movement of 12 marked control and mercury-exposed snails were measured in each plot. Bayesian models were used to analyze the data and evidence ratios were used to test the hypotheses. The results showed that the effects of fragmentation were consistent in both control and exposed treatments, with an increase in the cumulative displacement of organisms. However, mercury significantly reduced the movement of organisms in all levels of fragmentation, shifting their foraging behavior (evidence ratio > 1000). Exposed snails were more likely to be found inactive in comparison with the control treatment (evidence ratio > 1000). Fragmentation also reduced the vertical movement of organisms in both treatments. In contrast, mercury increased the vertical movement of organisms (evidence ratio > 1000). The search efficiency of organisms also increased in a highly fragmentated landscape, suggesting that changes in foraging behavior are likely due to reduced resources and consequently increase in foraging effort. The present study shows that mercury exposure can enhance the effects of habitat fragmentation by changing organisms' movement, foraging behavior, and search efficiency.

Abstract
Vinca sardoa (Stearn) Pignatti, known as Sardinian periwinkle, is widely diffused in Sardinia (Italy). This species contains indole alkaloids, which are known to have a great variety of biological activities. This study investigated the antileukemic activity against a B lymphoblast cell line (SUP-B15) of V. sardoa alkaloid-rich extracts obtained from plants grown in Italy, in Iglesias (Sardinia) and Rome (Latium). All the extracts showed a good capacity to induce reductions in cell proliferation of up to 50% at the tested concentrations (1-15 µg/mL). Moreover, none of the extracts showed cytotoxicity on normal cells at all the studied concentrations.

Abstract
The aim of the work was to investigate the possible biodegradation of such stable plastics as fluorated acrylic copolymer Protacryl-M and polytetrafluoroethylene-teflon (PTFE)-that are widely applied in medicine for prosthetics in dentistry and orthopedics. Our tasks were as follows: 1. To select a suitable marine biological object (multicellular invertebrate) 2. To develop a method for delivering microplastic particles (MP) of selected plastics to the gastrointestinal tract (GIT) of an experimental animal 3. To develop a technique for separating MP particles from animal feces 4. To develop a technology for multiple passages of MP particles through the gastrointestinal tract of an animal 5. To select methods and techniques for determining the degradation of the surface of MP particles after passing through the gastrointestinal tract of the animal The effect of a biological agent on the types of plastic above is considered using marine gastropods of the genus Littorina (in particular, the periwinkle L. brevicula) as a model organism widely distributed in the marine intertidal zone.

Abstract
Vinca minor, also known as the lesser periwinkle, is a well-known species from the Apocynaceae, native to central and southern Europe. This plant synthesizes monoterpene indole alkaloids, which are a class of specialized metabolites displaying a wide range of bioactive- and pharmacologically important properties. Within the almost 50 monoterpene indole alkaloids it produces, V. minor mainly accumulates vincamine, which is commercially used as a nootropic. Using a combination of Oxford Nanopore Technologies long read- and Illumina short-read sequencing, a 679,098 Mb V. minor genome was assembled into 296 scaffolds with an N50 scaffold length of 6 Mb, and encoding 29,624 genes. These genes were functionally annotated and used in a comparative genomic analysis to establish gene families and to investigate gene family expansion and contraction across the phylogenetic tree. Furthermore, homology-based monoterpene indole alkaloid gene predictions together with a metabolic analysis across 4 different V. minor tissue types guided the identification of candidate monoterpene indole alkaloid genes. These candidates were finally used to identify monoterpene indole alkaloid gene clusters, which combined with synteny analysis allowed for the discovery of a functionally validated vincadifformine-16-hydroxylase, reinforcing the potential of this dataset for monoterpene indole alkaloids gene discovery. It is expected that access to these resources will facilitate the elucidation of unknown monoterpene indole alkaloid biosynthetic routes with the potential of transferring these pathways to heterologous expression systems for large-scale monoterpene indole alkaloid production.

Abstract
There are different ways contaminants can interact and enhance the effects of habitat fragmentation, such as modifying the movement of organisms. The present study tested the hypothesis that mercury exacerbates the effects of fragmentation by affecting the movement of the marsh periwinkle Littoraria irrorata and reducing the probability of snails crossing fragmented microlandscape experimental systems. How these changes could affect the search efficiency of organisms in the long term was assessed using hidden Markov models and random walks simulations. Bayesian nonlinear models were used to analyze the effects of fragmentation and contamination on the mean speed and mean directional change of organisms. Snail movement for control and two mercury-exposure treatments were recorded in microlandscapes with six different levels of habitat cover and three landscape replicates. The results indicated that exposed organisms had lower probabilities of crossing the landscape, reduced speed, and shifts in step length distributions. Both mercury exposure and habitat fragmentation affected the movement of the marsh periwinkle. Mercury exacerbated the effects of habitat fragmentation by affecting the cognition (e.g., route planning, orientation, and spatial learning) and movement of L. irrorata. Hence, the interaction of these stressors could further reduce the functional connectivity of landscapes and reduce the search efficiency of organisms.

Abstract
AbstractPhysiological processes influence how individuals perform in various environmental contexts. The basis of such processes, metabolism, scales allometrically with body mass and nonlinearly with temperature, as described by a thermal performance curve. Past studies of thermal performance curves tend to focus on effects of temperature on a single body size or population, rather than variation in the thermal performance curve across sizes and populations. Here, we estimate intraspecific variation in parameters of the thermal performance curve in the salt marsh gastropod Littoraria irrorata. First, we quantify the thermal performance curve for respiration rate as a function of both temperature and body size in Littoraria and evaluate whether the thermal parameters and body size scaling are interdependent. Next, we quantify how parameters in the thermal performance curve for feeding rate vary between three Littoraria populations that occur along a latitudinal gradient. Our work suggests that the thermal traits describing Littoraria respiration are dependent on body mass and that both the thermal traits and the mass scaling of feeding vary across sites. We found limited evidence to suggest that mass scaling of Littoraria feeding or respiration rates depends on temperature. Variation in the thermal performance curves interacts with the size structure of the Littoraria population to generate divergent population-level responses to temperature. These results highlight the importance of considering variation in population size structure and physiological allometry when attempting to predict how temperature change will affect physiological responses and consumer-resource interactions.

Abstract
To assess the toxic potential of the alkaloids, a quantification method is necessary. An ion pair extraction method was used for quantitative fluorometric determination of vincamine, protopine and all contained alkaloids in the mother tinctures of Vinca minor and Fumaria officinalis. The non-fluorescent alkaloids were transformed into an ion pair with sodium-9,10-dimethoxy-anthracene-sulfonate and then fluorometrically determined and quantified in this study. The applicable ion pair was extracted in a suitable organic solvent, where dichloromethane has proven to be beneficial. Conditions for the ion pairing and fluorometric quantification are given. The recovery rate was used to investigate the quality of determinability and the influence of the mother tincture matrix. The method was applied to determine the concentration of protopine in the range 0.1 - 15 μg/ml and of vincamine in the range of 0.5 - 20 μg/ml. The limit of detection was < 0.3 μg/ml, and the limit of quantification < 0.9 μg/ml for both alkaloids.

Abstract
Madagascar periwinkle (Catharanthus roseus, family Apocynaceae) is a reservoir of more than 130 monoterpene indole alkaloids (MIAs) including the famous anti-neoplastic dimeric MIAs vinblastine and vincristine, and anti-hypertensive monomeric MIAs ajmalicine and serpentine. Understanding the biosynthetic steps and regulatory factors leading to the formation of MIAs is crucial for rational engineering to achieve targeted enhancement of different MIAs. Due to its highly recalcitrant nature, C. roseus is considered genetically non-tractable for transformation at the whole-plant level. Though few reports have demonstrated tissue culture-mediated regeneration and transformation of C. roseus at whole-plant level recently, the efficiency and reproducibility of these protocols have been a major challenge. To overcome this, we have developed a tissue-culture-independent Agrobacterium-mediated in planta transformation method in C. roseus. Using this method, we were able to efficiently generate stable transgenic plants without relying on the cumbersome methods of tissue-culture regeneration and transformation. Moreover, the transformed plants obtained through this in planta method exhibited stability in subsequent generations. Our method is useful not only for the elucidation of biosynthetic and regulatory steps involved in MIA formation through transgenic plant approach but also for metabolic engineering at the whole-plant level in C. roseus.

Abstract
Prior studies indicated salt marsh periwinkles (Littoraria irrorata) were strongly impacted in heavily oiled marshes for at least 5 years following the Deepwater Horizon oil spill. Here, we detail longer-term effects and recovery over nine years. Our analysis found that neither density nor population size structure recovered at heavily oiled sites where snails were smaller and variability in size structure and density was increased. Total aboveground live plant biomass and stem density remained lower over time in heavily oiled marshes, and we speculate that the resulting more open canopy stimulated benthic microalgal production contributing to high spring periwinkle densities or that the lower stem density reduced the ability of subadults and small adults to escape predation. Our data indicate that periwinkle population recovery may take one to two decades after the oil spill at moderately oiled and heavily oiled sites, respectively.

Abstract
The Deepwater Horizon (DWH) oil spill resulted in the release of millions of barrels of oil into the Gulf of Mexico, and some marsh shorelines experienced heavy oiling including vegetation laid over under the weight of oil. Periwinkle snails (Littoraria irrorata) are a critical component of these impacted habitats, and population declines following oil spills, including DWH, have been documented. This study determined the effects of oil on marsh periwinkle movement and survivorship following exposure to oil. Snails were placed in chambers containing either unoiled or oiled laid over vegetation to represent a heavily impacted marsh habitat, with unoiled vertical structure at one end. In the first movement assay, snail movement to standing unoiled vegetation was significantly lower in oiled chambers (oil thickness ≈ 1 cm) compared to unoiled chambers, as the majority (∼75%) of snails in oiled habitats never reached standing unoiled vegetation after 72 h. In a second movement assay, there was no snail movement standing unoiled structure in chambers with oil thicknesses of 0.1 and 0.5 cm, while 73% of snails moved in unoiled chambers after 4h. A toxicity assay was then conducted by exposing snails to oil coated Spartina stems in chambers for periods up to 72 h, and mortality was monitored for 7 days post exposure. Snail survival decreased with increasing exposure time, and significant mortality (∼35%) was observed following an oil exposure of less than 24 h. Here, we have shown that oil impeded snail movement to clean habitat over a short distance and resulted in oil-exposure times that decreased survival. Taken together, along with declines documented by others in field surveys, these results suggest that marsh periwinkle snails may have been adversely affected following exposure to DWH oil.

Abstract
Globally, the prevalence of chronic, noncommunicable diseases is increasing at an alarming rate and diabetes is one of them. If diabetes is not controlled then a lot of complication like coronary artery disease, cerebrovascular disease, peripheral vascular disease, retinopathy, nephropathy and neuropathy arise in diabetic patients and causes morbidity and/or mortality. Diabetes is increasing at an epidemic form and in near future the largest increases will take place in the regions dominated by developing economies. So, it will be a great social and economical burden to developing countries as well as the developed. But if we be aware about our diet and lifestyle and take proper medication we may prevent and reduce the prevalence of diabetes. Oral medicine plays an important role in management of diabetes. But most of the oral drugs are costly and have a lot of side effects. For this it is also necessary to take medicines with fewer or no side effects. And antidiabetic medicinal plants may play an important role in this case. In this article we have tried to describe how diet and lifestyle with using medicinal plants may help to prevent or maintain diabetes and help to reduce the mortality and morbidity due to diabetes or complication related to it.

Abstract
Vinca minor L. (Apocynaceae) is a medicinal plant that has long been used to treat cerebral and memory disorders in European folk medicine. Furthermore, it contains more than 50 alkaloids, some of them having bisindole structure such as the antineoplastic alkaloids present in Catharanthus roseus (L.) G. Don (Apocynaceae). In this study, the plant's alkaloid extract was divided into three fractions and the cytotoxic effects on cell proliferation of HT-29, Caco-2, T47D, and NIH/3T3 cell lines were examined. All alkaloid fractions showed a dose-dependent cytotoxic effect on the cell lines. IC(50) values confirmed that the growth and proliferation of NIH/3T3 cells were less affected in comparison to other cell lines.

Abstract
INTRODUCTION Hemorheological factors play an important role in the pathomechanism of ischemic cerebrovascular disorders. Abnormal rheological conditions in patients with chronic cerebrovascular disease predispose for recurrent strokes. Vinpocetine (VP), a synthetic ethyl esther of apovincamine, has successfully been used in the treatment of cerebrovascular diseases, in part because of its favourable rheological effects. PATIENTS AND METHODS The study investigates the hemorheological changes in 40 patients in the chronic stage of ischemic cardiovascular disease after administration of vinpocetine. All patients received a high dose of intravenous VP in doses gradually increased to l mg/kg/day. In addition, 20 patients (mean age: 61+/-8 years) received 30 mg VP orally for 3 months. The other 20 patients (mean age: 59+/-6 years), who received placebo tablets, served as controls. Hemorheological parameters (hematocrit, plasma fibrinogen, whole blood viscosity, red blood cell aggregation and deformability) were evaluated at 1 and 3 months. RESULTS The high-dose parenteral VP significantly decreased red blood cell aggregation, plasma and whole blood viscosity (p < 0.05) compared to the initial values. In patients with additional oral treatment, plasma and whole blood viscosities were significantly lower compared to the placebo patients at 3 months (p < 0.05). CONCLUSION Our results confirmed the beneficial rheological effects of high-dose parenteral VP (partially caused by hemodilution) observed previously, and also warrant its long-term oral admission to maintain the beneficial rheological changes.

Abstract
Citrus huanglongbing (HLB) or yellow shoot disease (i.e., greening disease) is highly destructive to citrus production worldwide. Understanding the etiology of HLB is critical for managing the disease. HLB is currently associated with infection by 'Candidatus Liberibacter spp.' around the world, including China. However, Koch's postulates have not been fulfilled. In addition, other plant pathogens also may be involved in HLB. In a survey performed in Guangdong Province, P. R. China in 2006 and 2007, 141 citrus samples showing typical symptoms of HLB from 11 different cities were collected. Polymerase chain reaction (PCR) using phytoplasma-specific primer sets fU5/rU3 nested with primer set P1/P7 identified 110 (78.0%) positive samples. A 1,785-bp amplicon was obtained with primer set P1/P7. Analysis showed a 100% identity of this sequence in the region of 16S rDNA and 16S-23S rRNA intergenic transcribed spacer to three strains of 'Candidatus Phytoplasma asteri' (onion yellows [Japan], aster yellows 'watercress' [Hawaii], and valeriana yellows [Lithuania]). Of the 141 samples, 89 (63.1%) samples were positive for 'Ca. Liberibacter asiaticus'. When mixed infection was considered, 69 (48.9%) samples were positive for both 'Ca. P. asteri' and 'Ca. L. asiaticus'. Transmission electron microscopy (TEM) showed low titers of both walled and wall-less bodies in the phloem sieve tubes of HLB citrus. When transmission from symptomatic citrus to periwinkle (Catharanthus roseus) via dodder (Cuscuta campestris) was conducted, both phytoplasma and 'Ca. L. asiaticus' were detected from the affected periwinkle. In addition to yellowing/mottling, the infected periwinkle showed symptoms of virescence and phyllody which are commonly associated with phytoplasmal diseases. TEM analysis of affected periwinkle revealed pleomorphic and wall-less organisms, characteristic of phytoplasmas, filling some phloem sieve tubes. In contrast, walled bacteria were at low titer. This study showed that in addition to 'Ca. L. asiaticus', a phytoplasma related to 'Ca. P. asteri' could also be detected in citrus showing HLB symptoms in Guangdong.

Abstract
Uptake and depuration of (131)I into winkles through consumption of the diatom Skeletonema costatum is described. The work follows on from previous studies that investigated the uptake of iodine into winkles from seawater and seaweed. Incorporation of (131)I in S. costatum from labelled seawater followed linear first-order kinetics with an uptake half-time of 0.40 days. Iodine uptake in winkles from labelled S. costatum also followed linear first-order kinetics, with a calculated equilibrium concentration (C(infinity)) of 42Bqkg(-1) and a transfer factor (TF) of 1.1x10(-4) with respect to labelled diatom food. This TF is lower than that observed for uptake of (131)I in winkles from labelled seaweed. For the depuration stage, a biphasic sequence with biological half-lives of 1.3 and 255 days was determined. The first phase is biokinetically important, given that winkles can lose two-thirds of their activity during that period. This study shows that, whilst winkles can obtain radioactive iodine from phytoplankton consumption, they do not retain the majority of that activity for very long. Hence, compared with other exposure pathways, such as uptake from seawater and macroalgae, incorporation from phytoplankton is a relatively minor exposure route.

Abstract
Although mixed air pollutants generated from traffic are suspected as one of the causes of DNA damage in living species, effects of the combination of these pollutants and other micro-environmental factors on urban biota have not been clarified yet. Thus, this study mainly aimed to detect the genetic damages in selected plant biomonitors, which were ginkgo (Ginkgo biloba), pohtos (Epipremnum aureum), and periwinkle (Vinca rosea), setting in roadside and non-roadside environments. Two monitoring positions were selected in the Hongo campus of the University of Tokyo, Japan. This area was categorized as the urban residential zone. Both roadside and non-roadside samples were analyzed by using comet assay protocol. Different distribution changes in DNA migration ratios of all species could be observed and further interpreted as percentages of DNA damage. For all test species, in the final stage of experiment, roadside samples showed significantly higher degrees of DNA damage than non-roadside one. Time-dependent response pattern of each species to the overall environmental stresses was performed. Increase in the percentages of DNA damage could be expressed by regression equations. In addition, ratio of percentage of DNA damage between roadside and non-roadside species (R/N ratio) was introduced in order to clarify the additional genetic effect caused by roadside air pollutants. Series of response phase of plant under stresses, including cell destabilization, damage intensification, and re-stabilization, were explained. This study might be applied as a preliminary method in urban air quality assessment for detecting the existing effects of air pollutants and micro-environmental stress in an urban ecosystem.

Abstract
AIMS Partial genetic characterization of several chromosomal regions on 35 16SrI-B phytoplasma strains maintained in periwinkle and collected in different geographical areas from plants of diverse species. METHODS AND RESULTS Genes coding for ribosomal protein rpL22, elongation factor EF-Tu and random cloned sequences amplified with primers AY19p/m, G35p/m and BB88F1/R1 after RFLP analyses showed a high degree of polymorphism among the strains studied. The ribosomal protein (rp) subgroups B and K, and an undescribed subgroup designated N, were identified. Amplicons obtained with primers AY19p/m and BB88F1/R1, revealed a high and a low degree of polymorphism, respectively. CONCLUSIONS A probable spacer role could be attributed to the AY19p/m sequence and a possible coding function to the BB88F1/R1 sequence. No relationship was found among genetic polymorphisms, identified by statistical analyses, and epidemiological or biological parameters. SIGNIFICANCE AND IMPACT OF THE STUDY The analyses of five different genomic sequences of the 35 strains belonging to subgroup 16SrI-B allowed a finer distinction among them, confirming that the polymorphism level of 16S rDNA is too low to be adopted as unique parameter for classification.
