The widely recognized anti-cancer potential of aspirin has created a broad interest to explore the clinical benefits of aspirin in cancer therapy. Takinib clinical trial However, the current understanding of the molecular mechanisms involved in the anti-cancer potential of aspirin remains limited.

Cancer stemness assays which contained ALDH, side population, chemo-resistance, sphere formation, and tumorigenesis were performed to validate aspirin function in vitro and in vivo. Histone modification assay was performed to check the effect of aspirin on histone methylation as well as the activity of HDAC and KDM6A/B. Inhibitor in vivo assay was performed to evaluate therapeutic effects of various inhibitor combination manners.

In regards to in vitro studies, aspirin diminishes cancer cell stemness properties which include reducing the ALDH+ subpopulation, side population, chemo-resistance, and sphere formation in three cancer types. In regards to in vivo studies, aspirin decreases tumor growth and metastasis and prolongs survivalspirin in the prevention of cancer progression.

The low fertility of highly weathered soils has been a major problem for resource-constrained smallholder farmers. In central Uganda, smallholder farmers have been collecting termite mound soils anywhere around the termite mound to improve their soil fertility. However, no studies have been conducted on which sections of the termite mounds consist of high soil nutrients. This study was conducted to assess selected major soil essential plant nutrients of soils collected from the top of the mound (TPMS), and the basal part of the mound (BPMS). The surrounding soil samples were collected from five, fifteen, and thirty meters away from the mound (TMSS1, TMSS2, and TMSS3 respectively), covering ten termite mounds in five different maize fields in central Uganda.

TPMS and BPMS had significant (P-value < 0.05) higher N, P, K, OC, Ca and Mg levels than TMSS1, TMSS2, and TMSS3. However, OC levels in BPMS was higher than TPMS. On the whole, termite mounds are beneficial as a source for essential plant nutrients. It will be best if smallholder farmers could collect the termite mound soils from the top and the basal part of the mound to improve the fertility of their soil.

Hyaluronidase produced by infective larvae of H. contortus can degrade hyaluronic acid present in the host's abomasal tissue. Thus, it facilitates larval tissue invasion and early establishment. We herein explored this ability of hyaluronidase in H. contortus, and tested whether hyaluronidase is utilized as a virulence factor by H. contortus while establishing the infection. We first successfully blocked the hyaluronidase gene in L3 larvae by RNA interference (RNAi), which was subsequently confirmed by qPCR, enzymatic activity, and immunohistochemistry assays. Using these larvae we then conducted in vivo and in vitro assays on sheep to assess the effects of hyaluronidase suppression on larval invasion and establishment of infection. The in vivo assay showed a significant drop in worm burden in siRNA treated group in comparison to control group. During in vitro assay we applied an ovine ex vivo model where siRNA treated group of larvae showed significantly reduced invasion of the abomasal tissue explants as compared to control group. These findings indicate that hyaluronidase plays a key role in host's tissue invasion and larval establishment, and it is used as a virulence factor by H. contortus while establishing the infection. As an invasive virulence molecule, its functional research is thus conducive to the prevention of haemonchosis.

The rapid development of single-cell RNA-sequencing (scRNA-seq) technologies has led to the emergence of many methods for removing systematic technical noises, including imputation methods, which aim to address the increased sparsity observed in single-cell data. Although many imputation methods have been developed, there is no consensus on how methods compare to each other.

Here, we perform a systematic evaluation of 18 scRNA-seq imputation methods to assess their accuracy and usability. We benchmark these methods in terms of the similarity between imputed cell profiles and bulk samples and whether these methods recover relevant biological signals or introduce spurious noise in downstream differential expression, unsupervised clustering, and pseudotemporal trajectory analyses, as well as their computational run time, memory usage, and scalability. Methods are evaluated using data from both cell lines and tissues and from both plate- and droplet-based single-cell platforms.

We found that the majority of and SAVER were found to outperform the other methods most consistently.

The prevalence of hyperlipidemia continues to increase due to aging and lifestyle changes. Statins are currently used as the first choice for treating hyperlipidemia, but are limited by adverse reactions. Hwangryunhaedok-tang (HHT) has received attention as a promising intervention for hyperlipidemia through a few experimental and clinical trials. This study aims to explore the feasibility, effectiveness, and safety of HHT for hyperlipidemia treatment.

This is a study protocol for a randomized, double-blind, placebo-controlled, parallel, investigator-initiated, pilot clinical trial held in Daejeon, Republic of Korea. Thirty patients with hyperlipidemia will be randomly allocated to HHT or placebo granule groups in equal proportions. Participants will be administered HHT or placebo granules three times per day for 8 weeks and followed up for another 4 weeks. The primary outcome is low-density lipoprotein cholesterol at 8 weeks from the commencement of treatment. Other blood lipid parameters, biomarkers of atherosclerosis, the degree of arteriosclerosis, blood glucose parameters, blood pressure, anthropometric parameters, health-related quality of life, and the changes in the general symptoms of cold and hot patterns will be measured as secondary outcomes.
