The Intensity of Treatment Rating (ITR) Scale condenses treatment and clinical characteristics into a single measure to study treatment effects on downstream health outcomes across cancer types. This rating was originally developed for clinicians to determine from medical charts. However, large studies are often unable to access medical charts for all study participants. We developed and tested a method of estimating treatment intensity (TI) using cancer registry and patient self-reported data.
We estimated two versions of TI for a cohort of pediatric cancer survivors-one utilized information solely available from cancer registry variables (TI
) and the other included registry and self-reported information (TI
) from survey participants. In a subset of cases (n = 135) for whom the gold standard TI (TI
) was known, both TI
and TI
were compared to TI
by calculating percent agreement and weighted Cohen’s kappa, overall and within cancer subtypes.
In comparison to TI
, 71% of TI scores from both mffects of treatment during survivorship in registry-based epidemiological studies.
Oncolytic virus therapy has shown benefits for multiple cancers, while limitations remain for traditional treatment. However, few studies have concentrated on comparing whether oncolytic virus combined with traditional treatment is better than traditional treatment alone in patients with cancer. We conducted a meta-analysis of the curative effect and safety of oncolytic virus combination therapy.
We searched the PubMed, Embase, Cochrane Library, and Web of Science databases comprehensively for articles comparing oncolytic virus combined with traditional treatment to traditional treatment alone in patients with cancer. A meta-analysis and trial sequential analysis were performed.
A total of 12 studies involving 1494 patients (combination therapy group, 820 patients; traditional treatment group, 674 patients) were included in the study. Compared with traditional treatment alone, combination therapy was significantly associated with high objective response rate [odds ratio (OR) 1.35, 95% confidence interval (CI) 1.01-1.82, p = 0.04]. There were no significant differences for other outcomes such as 1- and 2-year survival rate, and 4- and 12-month progression-free survival rate. Combination therapy was significantly associated with high incidence of grade ≥ 3 adverse effects (OR 1.47, 95% CI 1.06-2.05, p = 0.02) and high incidence of grade ≥ 3 neutropenia (OR 1.65, 95% CI 1.13-2.43, p = 0.01). There were no significant differences for other grade ≥ 3 adverse effects, e.g., gastrointestinal adverse effects, influenza-like illness, fatigue, anemia, and thrombocytopenia.
Despite partially increased toxicity, the combination therapy improves the effectiveness of cancer treatment. However, high-quality, large-scale studies are needed to evaluate its effectiveness and safety.

Sulphur-oxidizing bacteria play a key role in transformation of sulphur in soil. Oil seed crops require high amount of sulphur and it plays an important role in the formation of proteins, vitamins and enzymes. It increases yield, oil content and protein content in oil seed crops. Sulphur is the important constituent of amino acids, viz. methionine, cystine, and cysteine. It necessitates various enzymatic, metabolic processes such as photosynthesis and nitrogen fixation. In the last few years, the prominence of sulphur in oil seed crop nutrition has been accepted as widespread occurrence of its inadequacy in agricultural soil. Approximately 41% of Indian soil is deficient in sulphur. The soil microbial population is the major enforcement behind sulphur transformation. They mineralize, immobilize, oxidize and reduce the elemental and other reduced forms of sulphur. The main step in transformation is oxidation carried out by microorganisms to convert sulphur into sulphate. The chemolithotrophic bacteria belonging to genus Thiobacillus are of primary importance; there are heterotrophic bacteria also which can oxidize sulphur in soil. The pH reduction at the time of oxidation helps in mineralization and absorption of other essential nutrients also. This property of sulphur-oxidizing bacteria (SOB) shows their potential to be used as bioinoculants. Bioformulations prepared using carrier-based formulations, immobilization, biostimulation, etc., are sustainable forms of fertilizers. These SOB inoculants can be used to increase the fertility and sulphate production in soil.In a conserved culture of the purple sulfur bacterium Thiospirillum jenense DSM216T, cells of this species were easily recognized by cell morphology, large-size spirilla and visible flagellar tuft. The Tsp. jenense genome is 3.22 Mb in size and has a GC content of 48.7 mol%. It was readily identified as a member of the Chromatiaceae by the complement of proteins in its genome. A whole genome comparison clearly placed Tsp. jenense near Thiorhodovibrio and Rhabdochromatium species and somewhat more distant from Thiohalocapsa and Halochromatium species. This relationship was also found with the sequences of the photosynthetic reaction center protein PufM. The genome sequence supported important properties of this bacterium the presence of ribulose-bisphosphate carboxylase and enzymes of the Calvin cycle of autotrophic carbon dioxide fixation but the absence of carboxysomes, an incomplete tricarboxylic acid cycle and the lack of malate dehydrogenase, the presence of a sulfur oxidation pathway including adenylylsulfate reductase (aprAB) but absence of assimilatory sulfate reduction, the presence of hydrogenase (hoxHMFYUFE), nitrogenase and a photosynthetic gene cluster (pufBALMC). The FixNOP type of cytochrome oxidase was notably lacking, which may be the reason that renders the cells highly sensitive to oxygen. Two minor phototrophic contaminants were found using metagenomic binning one was identified as a strain of Rhodopseudomonas palustris and the second one has an average nucleotide identity of 82% to the nearest neighbor Rhodoferax antarcticus. It should be considered as a new species of this genus and Rhodoferax jenense is proposed as the name.
Endocrine disruptors (EDs) are exogenous substances able to impair endocrine system; consequently, they may cause numerous adverse effects. Over the last years, particular focus has been given to their harmful effects on reproductive system, but very little is known, especially in males. The aim of this review is to discuss the detrimental effects of EDs exposure on fetal testis development, male puberty, and transition age.
A search for the existing literature focusing on the impact of EDs on fetal testis development, male puberty, andrological parameters (anogenital distance, penile length, and testicular volume), and testicular cancer with particular regard to pubertal age provided the most current information available for this review. Human evidence-based reports were given priority over animal and in vitro experimental results. Given the paucity of available articles on this subject, all resources were given careful consideration.
Information about the consequences associated with EDs exposure in em from the environment.This is the first genome-wide association study with the Hybrid Mouse Diversity Panel (HDMP) to define the genetic landscape of the variation in the suprathreshold wave 1 amplitude of the auditory brainstem response (ABR) both pre- and post-noise exposure. This measure is correlated with the density of the auditory neurons (AN) and/or the compliment of synaptic ribbons within the inner hair cells of the mouse cochlea. We analyzed suprathreshold ABR for 635 mice from 102 HMDP strains pre- and post-noise exposure (108 dB 10 kHz octave band noise exposure for 2 h) using auditory brainstem response (ABR) wave 1 suprathreshold amplitudes as part of a large survey (Myint et al., Hear Res 332113-120, 2016). Genome-wide significance levels for pre- and post-exposure wave 1 amplitude across the HMDP were performed using FaST-LMM. Synaptic ribbon counts (Ctbp2 and mGluR2) were analyzed for the extreme strains within the HMDP. ABR wave 1 amplitude varied across all strains of the HMDP with differences ranging between 2.lore the genetic landscape of suprathreshold wave 1 amplitude measurements of the mouse ABR. We have defined two genomic regions associated with wave 1 amplitude variation prior to noise exposure and an additional two associated with variation after noise exposure.
Theileriosis, trypanosomosis and babesiosis are the three major haemoprotozoan diseases causing huge economic losses worldwide. Difficulty in diagnosis of these diseases lies with the detection of carrier state with low parasitemia and concurrent infection.
The present study was conducted to standardize and evaluate multiplex PCR assay for specific, fast and simultaneous detection of Theileria annulata, Trypanosoma evansi and Babesia bovis in bovines.
Positive parasitic DNA was obtained from microscopically positive samples. Simplex PCR assay was developed targeting repetitive nucleotide sequences for Trypanosoma evansi and gene coding enzyme carbamoyl phosphate synthetase II for Babesia bovis. For theileriosis conditions already standardized targeting cytochrome b gene was used. Gradient PCR assay was used to determine common amplification conditions and develop multiplex PCR assay. Limit of detection was determined using tenfold serial dilution of parasitic DNA. Blood samples collected from 117 bovinehly specific and can be used for easy, early, sensitive, specific and simultaneous diagnosis of haemoprotozoan diseases in epidemiological survey as a robust tool.Rheumatoid arthritis (RA) is a systemic autoimmune disease, which is characterized by a chronic fluctuating course and immune dysfunction, resulting in affecting the health and life quality of RA patients. Methotrexate (MTX), as the standard gold treatment of RA, has received more and more clinical applications and basic pharmacological research. In several observational studies, MTXR, and treatment responses in RA patients show that the ratio of MTXR and non- response is about 30%-50%, namely MTX resistance (MTXR). Extensive efforts have been made into the investigation of the mechanism and effective biomarkers in MTXR of RA. In this paper, we discuss the recent findings regarding the critical signaling pathways of MTXR in RA. Provide research targets and directions for a drug therapy that develop preventive strategies and effective treatments of MTXR.Fasciola hepatica (F. hepatica) is a well-known zoonotic parasite that is crucial for economic and public health worldwide. Quantitative proteomics studies have been performed on proteins expressed by F. hepatica to investigate the differential expression of proteomes in different growth phases. And the screening of several marker proteins for use as early diagnostic antigens is essential. In this study, high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was conducted to analyze the differences in the expression of F. hepatica somatic proteins in different growth phases. Furthermore, gene ontology (GO) functional annotation, KEGG metabolic pathway, and clustering analyses were also performed. LC-MS/MS identified 629, 2286, 2254, and 2192 proteins in metacercariae, juvenile flukes 28dpi, immature flukes 59dpi, and adult phases, respectively. GO analysis revealed that differentially expressed proteins (DEPs) were mainly involved in transport, localization, metabolism, enzyme regulation, protein folding and binding, and nucleoside and nucleotide binding.
