Machine learning (ML) algorithms have been used to forecast clinical outcomes or drug adverse effects by analyzing different data sets such as electronic health records, diagnostic data, and molecular data. However, ML implementation in phase I clinical trial is still an unexplored strategy that implies challenges such as the selection of the best development strategy when dealing with limited sample size. In the attempt to better define prechemotherapy baseline clinical and biomolecular predictors of drug toxicity, we trained and compared five ML algorithms starting from clinical, blood biochemistry, and genotype data derived from a previous phase Ib study aimed to define the maximum tolerated dose of irinotecan (FOLFIRI (folinic acid, fluorouracil, and irinotecan) plus bevacizumab regimen) in patients with metastatic colorectal cancer. see more During cross-validation the Random Forest algorithm achieved the best performance with a mean Matthews correlation coefficient of 0.549 and a mean accuracy of 80.4%; the best predictors of dose-limiting toxicity at baseline were hemoglobin, serum glutamic oxaloacetic transaminase (SGOT), and albumin. The feasibility of a prediction model prototype was in principle assessed using the two distinct dose escalation cohorts, where in the validation cohort the model scored a Matthews correlation coefficient of 0.59 and an accuracy of 82.0%. Moreover, we found a strong relationship between SGOT and irinotecan pharmacokinetics, suggesting its role as surrogates' estimators of the irinotecan metabolism equilibrium. In conclusion, the potential application of ML techniques to phase I study could provide clinicians with early prediction tools useful both to ameliorate the management of clinical trials and to make more adequate treatment decisions.
The objective of this study was to analyse the temporal trend of HPV vaccination coverage (VC) in Spain in women aged 15-55 years not included in systematic vaccination programmes during the period 2007-2020.

We assessed the vaccine coverage rate in this population based on three estimations 1) annual vaccination coverage with at least one dose (VCR≥1d), 2) annual VC for the full schedule (VCR3d), and 3) cumulative VC for the full schedule (aVCR).

Annual VCR≥1d and VCR3d were highest in 2008 (2.40% and 0.66% respectively) and subsequently decreased drastically in 2011 (0.55% and 0.15%). From 2017 to 2019 there was an increase from 1.4-fold to 1.6-fold, respectively, which decreased in 2020. In relation to aVCR, there was an increasing trend throughout the study period with approximately 4.03% of the study population having been vaccinated against HPV in 2020.

In Spain, the cumulative vaccination coverage against HPV in women between 15-55 years old not included in current vaccination programmes remains very low. Nonetheless, the temporal trend has shown a slight increase in recent years. Despite the COVID-19 pandemic in 2020, no significant negative impact on vaccination coverage has been observed in this population.

A K calibration dataset was acquired at 1-m intervals in three fully screened wells, and compared to KNMR estimates using the Schlumberger-Doll research (SDR) equation with published empirical constants developed from previous studies in unconsolidated sediments. While KNMR using published constants was within an order of magnitude of K, the agreement, overprediction, or underprediction of KNMR varied with the MS distribution in each well. An examination of the effects of MS on NMR data and site-specific empirical constants indicated that the exponent on T2ML (n-value in the SDR equation, representing the diffusion regime) was found to have the greatest influence on KNMR estimation accuracy, while NMR porosity did not improve the prediction of K. KNMR was further improved by integrating an MS log into the NMR analyses. A first approach detrended T2ML for the effects of MS prior to calculating KNMR , and a second approach introduced an MS term into the SDR equation. Both were found to produce similar refinements of KNMR in intervals of elevated MS. This study found that low frequency NMR logging with short echo times shows promise for sites with moderate to elevated MS levels, and recommends a workflow that examines parameter relationships and integrates MS logs into the estimation of KNMR .
Herpetic keratitis caused by the herpes simplex virus (HSV) is the most common form of ocular herpes that causes corneal blindness. Although treatments for herpes keratitis have improved in recent years. there is still considerable room for new treatments against viral infection that shows great promise. The aim of the study was to evaluate the effect of RNA interference on HSV Type 1 (HSV1) infection in vitro, first prophylactically then therapeutically.

The highly conserved glycoproteins D (gD) and E (gE) were chosen as targets for this study. Different small interfering RNA (siRNA) duplexes that target gD and gE were designed and chemically synthesized. link3 The recombinant adenovirus type 5 was developed and used as the vehicle with which we delivered the siRNA into the Vero cells infected with the HSV1 KOS strain. Evaluation of the efficacy of siRNA-mediated inhibition was performed either before virus inoculation (prophylactically) or after virus inoculation at the first appearance of lesions (therapeutically). The expression of messenger RNA encoding gD and gE was detected using a real-time polymerase chain reaction (qPCR). We analyzed HSV replication in Vero cells, cytotoxicity of HSV, and cell viability.

When used prophylactically, the siRNA-targeting gD and gE created a more marked decrease in viral titer than when used therapeutically. The transfection of cells with recombinant adenovirus containing the siRNA expression cassette was associated with very low cytotoxicity.

Adenovirus-mediated siRNA-targeting gD and gE genes effectively inhibit the replication of the HSV in Vero cells. In addition, these findings indicate that the prophylactic use of siRNA is far more effective at inhibiting HSV replication than the therapeutic use.

The two main applicable TEM technologies used in plant virology are negative staining and ultrathin section. Negative staining is mainly used to observe the high-resolution structure of virus particles under a transmission electron microscope. Sample preparation for negative staining is convenient and fast, making it suitable for studying the virions in crude sap or purified solution. A modification of negative staining, by combining immunological reaction, named as technique of immuno-negative staining, is used to enrich or identify viruses. Ultrathin section is used for ultrastructural cytopathological studies in the virus-infected host cells, including the morphology of virus particles, the structure of viral induced inclusion bodies, the subcellular distribution of virions and the structural alteration of the host cell induced by viral infection. Such information is valuable to analyze the behavior of virus in replication, assembly, and intercellular transportation, and thus to understand the viral infection cycle. The present chapter describes the operation details of negative staining and ultrathin section TEM.RNA in situ hybridization, a histological technique derived from Southern blotting and northern blotting, has been an important approach in biology studies for many years. In the studies of virus-plant interactions, RNA in situ hybridization provides a direct visualization of viral RNA in host plants. Here, we provide a detailed protocol for viral RNA in situ hybridization that has been successfully used to detect Cucumber mosaic virus genome (CMV) RNAs in shoots of N. benthamiana plants.Plant virus infections cause damages to all kinds of crops, and result in enormous economic and yield losses worldwide. Numerous reports indicated that many plant viruses are vertically transmitted through seeds, and cause severe disease symptoms on seedlings that again serve as secondary transmission sources in fields. Therefore, it is necessary to develop efficient methods to detect the seeds infected by viruses. Here, we describe a RT-PCR protocol for detection of Cucumber green mottle mosaic virus (CGMMV), a tobamovirus in cucurbitaceous crop seeds. This method can be easily adapted for diagnosis of other plant viruses such as Tomato brown rugose fruit virus in seeds.Diagnosis of fruit tree viruses has been challenging for a long time as viral titer is often low and unevenly distributed among different tissues and branches of fruit trees. It is necessary to develop effective and reliable detection systems to identify viral pathogens in fruit trees. In this chapter, I describe RT-PCR and its derivatives tube capture-based reverse-transcription PCR (TC-RT-PCR) and multiplex RT-PCR assays for detection and identification of latent viruses in apple and pear trees. Classical RT-PCR is composed of two steps including transcription of viral RNA using extracted total RNA and PCR amplification of viral cDNA. TC-RT-PCR includes a TC step to capture particles and nucleic acid mixtures from crude plant tissue extracts as template directly for the first single-strand DNA (cDNA) synthesis, followed by PCR to amplify the viral cDNA fragment for viral identification. The cDNA derived from total RNAs can also be used for a one-step multiplex PCR to simultaneously detect several viruses in a given sample. As perennial fruit trees are usually coinfected by several viruses in orchards, multiplex RT-PCR can save time and lower labor and material costs for viral detection. These nucleic acid-based methods are sensitive and may be adapted for detection and identification of diverse viruses from different tissue materials of fruit trees.Plant viruses cause severe damages to crop productions each year worldwide. To prevent the losses caused by plant viruses, it is necessary to develop specific and efficient diagnostic tools to detect viruses. Among the current virus detection techniques, serological detection methods are considered to be rapid, simple, sensitive, and high throughput. Therefore, serological detection methods such as double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA), triple antibody sandwich ELISA (TAS-ELISA), antigen coated plate-ELISA (ACP-ELISA), Dot-ELISA and tissue print-ELISA as well as colloidal gold immunochromatographic strip are now wildly used to detect viruses in plants. In this chapter, we describe the DAS-ELISA and Dot-ELISA methods, and their applications in the detection of Tomato spotted wilt virus (TSWV) infection in plants. These two methods can be easily adapted for diagnosis of other plant viruses.
