Hematological malignancies, including lymphoma, myeloma, and leukemia, constitute around 6.5% of all cancer cases and are frequently diagnosed annually. These cancers present unique challenges in sequencing compared to solid tumors, and there is currently no established pipeline for their comprehensive profiling. In this study, we analytically validate a 475-gene targeted DNA sequencing panel designed for analyzing mutations and select translocations in hematological neoplasms.
Studies with relatively large sample size as well as long-term follow-up focusing on adult craniopharyngioma (CP) patients are still lacking. We attempted to identify independent prognostic factors and establish a nomogram model to estimate survival rates for adult CP patients. The Surveillance, Epidemiology, and End Results database was used to obtain data on patients with CP. Univariable and multivariable Cox analyses were utilized to identify the prognostic factors of adult CP patients. A survival prediction model was constructed and its predictive performance was also assessed. A total of 991 patients (695 in training group and 296 in validation group) were eligible for final inclusion. Multivariate Cox analysis presented that age at diagnosis, marital status, race, tumor size, and surgery type were statistically significant prognostic factors for overall survival (all P < .05). A graphical predicting nomogram model was developed to calculate the predicted patients' survival probabilities at 1, 2, 5, and 10 years. The concordance indexes were 0.708 ± 0.019 and 0.750 ± 0.025 for the training and validation samples, respectively, demonstrating favorable discrimination abilities. Similarly, the time-dependent area under curve also showed overall satisfactory discrimination ability. Favorable consistencies between the predicted and actual survival were presented according to the calibration curves. An easy-to-use nomogram, being proven to be with reliable discrimination ability and accuracy, was established to help predict overall survival for adult patients with CP using the identified significant prognostic factors.
Assessing causal effects in the presence of unobserved confounding is a challenging problem. Existing studies leveraged proxy variables or multiple treatments to adjust for the confounding bias. In particular, the latter approach attributes the impact on a single outcome to multiple treatments, allowing estimating latent variables for confounding control. Nevertheless, these methods primarily focus on a single outcome, whereas in many real-world scenarios, there is greater interest in studying the effects on multiple outcomes. Besides, these outcomes are often coupled with multiple treatments. Examples include the intensive care unit (ICU), where health providers evaluate the effectiveness of therapies on multiple health indicators. To accommodate these scenarios, we consider a new setting dubbed as multiple treatments and multiple outcomes. We then show that parallel studies of multiple outcomes involved in this setting can assist each other in causal identification, in the sense that we can exploit other treatments and outcomes as proxies for each treatment effect under study. We proceed with a causal discovery method that can effectively identify such proxies for causal estimation. The utility of our method is demonstrated in synthetic data and sepsis disease.
<p>Figure S6 The comparison of expression levels of phospho-ERK and phospho-Smad4 between lean and overweight/obesity patients, Related to Figure 7. Staining was analyzed by using a system based on the percentage of positively stained cells and the staining intensity. Integrated optical density of all the positive staining in each image was determined, and its ratio to total area of each photograph was calculated as density.</p>
<p>Figure S5 USP9x is responsible for TGF-beta-induced SMAD4 deubiquitination, Related to Figure 5. MDA-MB-231 cells were transfected with WT-SMAD4, HA-ubiquitin, and the indicated shRNAs and incubated with BSA or PA in the presence or absence of 3 ng/ml TGF-beta1 for 2 h. The effective knockdown of USP9x was confirmed by Western blot analysis before ubiquitination assays. Nuclear SMAD4 monoubiquitination (Mono-Ub) was detected by anti-SMAD4 immunoprecipitation and immunoblot with HA-ubiquitin. The blot is a representative of 3 blots from 3 independent experiments. *P<0.05 vs Control (shControl/-TGF-beta/-PA); #P<0.01 vs shControl/-PA; $P<0.05 shControl/+PA.</p>
The current research on interaction between catechin and protein has focused on non-covalent crosslinking, however, the mechanism of free radical-induced crosslinking between catechin and β-lactoglobulin (BLG) is not known. In this study, BLG bound to four catechins [epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG)]. The structure change of complex was investigated by circular dichroism spectroscopy, ultraviolet-visible (UV-vis) spectroscopy and Acid and 8-Anilino-1-naphthalenesulfonic acid (ANS) fluorescence spectroscopy. M cell model was constructed to evaluate the transintestinal epithelial transport capacity of complex digestive products. The results showed that catechins were covalently bound to BLG by C-S and C-N bonds and their binding content was EGCG>EGC>ECG>EC. Moreover, catechins could change the secondary structure of BLG, with the decrease of α-helix and reduction of the irregular coilings, which leads to the loose spatial structure of the protein. Moreover, the catechin could enhance further the digestibility of BLG. Transport capacity of digestive products of M cell model was about twice of that of the Caco-2 cell model, indicating that M cell model had better antigen transport capacity. The difference between groups indicated that the transport efficiency of digestive products was decreased with the presence of catechin, in which BLG-EGCG and BLG-EGC groups were transported more strong than those of BLG-EC and BLG-ECG groups. The transport efficiency of BLG-catechin complexes were lower than that of BLG, indicating that catechin had the protective and repair roles on intestinal barrier permeability.
Although chronic lateral instability of the ankle is a common disorder, there are not many reports and researches on it in China. This is because most patients with the condition do not seek a thorough cure of it and consequently surgeons pay little attention to it. In this article, we discuss some of the problems about its diagnosis, describe and compare several surgical procedures for reconstruction of the lateral ligament. We hope this paper can help surgeons know more about how to make an accurate diagnosis of the chronic lateral instability of the ankle and how to deal with it.
