Exercise capacity is a valuable trait in horses, and it has been used as one of their selection criteria. Although exercise affects molecular homeostasis and adaptation in horses, the mechanisms underlying these effects are not fully understood. This study was carried out to identify changes in the blood profiles of microRNAs (miRNAs) and mRNAs induced by exercise in horse leukocytes. Total RNAs isolated from the peripheral blood leukocytes of four Warmblood horses before and after exercise were subjected to next-generation sequencing (NGS) and microarray analyses to determine the miRNA and mRNA expression profiles, respectively...

Connections between the hippocampus (HC) and medial prefrontal cortex (mPFC) are critical for working memory; however, the precise contribution of this pathway is a matter of debate. One suggestion is that it may stabilize retrospective memories of recently encountered task-relevant information. Alternatively, it may be involved in encoding prospective memories, or the internal representation of future goals. To explore these possibilities, simultaneous extracellular recordings were made from mPFC and HC of rats performing the delayed spatial win-shift on a radial maze...

BACKGROUND: Treatment of basilar artery aneurysms is challenging. While endovascular techniques have dominated, there still remain circumstances where open surgical clipping is required or preferred. Minimally invasive "keyhole" approaches are being used more frequently to provide the durability of surgical clipping with a lower morbidity profile; however, careful patient selection is required. The supraorbital "keyhole" approach has been described for the treatment of basilar artery aneurysms, but careful assessment of the basilar exposure is necessary to ensure proper visualization of the aneurysm and ability to obtain proximal vascular control...

The anticancer immune defense mechanism involves humoral and cellular responses. The main effector mechanisms of antitumor responses involve the following: the activity of cytotoxic T cells; the activation of macrophages and neutrophils; the activity of cytokines secreted by T cells; and natural killer cell activity. Selected cell populations are responsible for the stimulation or suppression of the immune system against tumor cells. Therefore, the aim of the present study was to evaluate the location, extent and composition of the cellular inflammatory infiltration of tumors in patients with colorectal cancer (CRC)...

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. BCL2 apoptosis regulator (BCL2) and marker of proliferation Ki-67 (Ki-67) are established prognostic markers, which have traditionally been assessed separately in DLBCL. However, no studies have evaluated the prognostic value of the combination of BCL2 and Ki-67 index. Thus, the present study aimed to analyze the prognostic value of combination of these two markers. Immunohistochemical analysis was used to assess the expression of BCL2 and Ki-67 in 274 cases of DLBCL...

A novel system auxiliary to the Union for International Cancer Control classification may allow the prognosis of patients with malignant tumors at similar stages to be predicted, as currently this is challenging. The present study generated a novel system to predict populations at low risk among patients with stage III/IV oral squamous cell carcinoma (OSCC). A total of 41 patients who were diagnosed at stages III/IV OSCC and underwent surgical tumor resection were analyzed. Band-like or follicular lymphocyte infiltration, intraepithelial micro-abscess formation and natural killer (NK) cell infiltration were histopathologically evaluated...

B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E is the most common kinase-activating mutation and is associated with poor prognosis in melanoma. However, the clinical significance of kinase-impairing mutations remains unclear. The present study aimed to analyze kinase-impairing mutations in BRAF codons 594 and 596 in non-Caucasian patients with melanoma and to investigate their possible clinical significance. To detect hotspot mutations, exon 15 of the BRAF gene was amplified using polymerase chain reaction in samples from 1,554 patients with melanoma...

Ovarian cancer is the eighth most common cancer and the seventh highest cause of cancer-associated mortality in women worldwide. It is the second highest cause of mortality among female reproductive malignancies. The current standard first-line treatment for advanced ovarian cancer includes a combination of surgical debulking and standard systemic platinum-based chemotherapy with carboplatin and paclitaxel. Although a deeper understanding of this disease has been attained, relapse occurs in 70% of patients 18 months subsequent to the first-line treatment...

Non-small cell lung cancer (NSCLC) patients with squamous cell carcinoma (SCC) histology have limited chemotherapeutic options. Treatment with S-1 combined with carboplatin (CBDCA) has been shown to provide a significant survival benefit in SCC patients compared with treatment with combined CBDCA and paclitaxel. The aim of the present study was to investigate the association between the expression of molecular markers related to the pharmacological action of S-1, including thymidylate synthase (TS), orotate phosphoribosyltransferase (OPRT) and dihydropyrimidine dehydrogenase (DPD), and the clinical efficacy of S-1-based chemotherapy in SCC patients...

The increasing incidence of obesity and diabetes due to changes in diet, earlier menarche, delayed menopause, late marriage, and declining birth rate have resulted in an increase in the number of endometrial cancer cases over the last few decades. Although surgical therapy is sufficient for early endometrial cancer, there is no effective therapy for patients with advanced and recurrent endometrial cancer. The oncogenic mechanism of endometrial cancer involves microsatellite instability (MSI) caused by dysfunction of DNA mismatch repair genes in 30% of patients...

Ovarian cancer is the most common gynecological malignant cancer in female genitalia. Dysregulation or dysfunction of microRNAs (miRs) contribute to cancer development. The role of miR-520b in ovarian cancer remains unclear. The present study investigated the role of miR-520b in ovarian cancer and determined that the expression levels of miR-520b in ovarian cancer tissues and cell lines were upregulated. By contrast, reverse transcription-quantitative polymerase chain reaction and immunohistochemistry revealed that the mRNA and protein expression levels of ring finger protein 216 (RNF216) were downregulated in ovarian cancer, indicating that there was a negative correlation between miR-520b and RNF216...

Hepatocellular carcinoma (HCC) is prone to recurrence following curative treatment. The purpose of the present study was to identify the predisposing factors of HCC recurrence following complete remission achieved by transarterial chemoembolization (TACE). A retrospective cohort study of 70 consecutive patients with HCC who underwent TACE as the initial treatment was conducted. The patients were divided into two groups according to their 1-year disease-free survival (DFS) status; the early recurrence group (ER group; n=32), with HCC recurring within 1 year of initial TACE; and the non-early recurrence group (NER group; n=38), who did not experience recurrence within 1 year...
