Recently, it has been postulated as a metabolic hormone. Further, moderately higher levels of bilirubin are positively associated with reduced risk of cardiovascular diseases, diabetes, metabolic syndrome and obesity. However, due to poor solubility the therapeutic delivery of bilirubin remains a challenge. Nanotechnology offers unique advantages which may be exploited for improved delivery of bilirubin to the target organ with reduced risk of systemic toxicity. Herein, we postulate the use of intravenous administration or inhalational delivery of bilirubin nanomedicine (BNM) to combat systemic dysfunctions associated with COVID-19, owing to the remarkable preclinical efficacy and optimistic results of various clinical studies of bilirubin in non-communicable disorders. BNM may be used to harness the proven preclinical pharmacological efficacy of bilirubin against COVID-19 related systemic complications.Gastrointestinal (GIs) cancers are among the most common causes of cancer related death, and hence the importance for the identification of novel prognostic/predictive biomarkers for detection of patients at an early stage, and for using these to identify novel targeted therapies to improve the efficacy of existing chemotherapeutic regimens. Programmed cell death 1 has been reported as a potential target in several malignancies, and targeting agents are being developed, some already approved by FDA, such as pembrolizumab, Atezolizumab, Nivolumab. Pembrolizumab that have been approved for the treatment of metastatic non-small cell lung cancer. Here we provide an overview of the mechanism of action PD-1/PD-L1, prognostic value and current progress in clinical trials using PD-1/PD-L1 inhibitors, and the resistant mechanisms at underlie the inhibitory effect of these agents in the treatment of gastrointestinal cancers.
Insufficient high-intensity focused ultrasound (HIFU) can promote the rapid progression of the residual tumor through the hypoxia inducible factor-2α +(HIF-2α)/vascular endothelial growth factor A (VEGFA)/ephrin type-A receptor 2 (EphA2) pathway. Although sorafenib has been shown to significantly improve the survival of patients with advanced liver cancer, the use of sorafenib in residual tumor tissues following HIFU has rarely been elucidated. Thus, this study aimed to investigate the potential adjuvant therapeutic effects of sorafenib following HIFU in order to reduce the relapse rate following insufficient HIFU.
Xenograft tumors were established using nude mice injected with liver cancer cells. At approximately 4 weeks after the inoculation of the tumor cells (tumors reached 1.3-1.5 cm), all mice were randomly divided into 3 groups as follows i) The control group (no treatment); ii) the HIFU-alone group, and iii) the combination group (HIFU + sorafenib), with 6 mice per group. The residual tumor volumelowing HIFU ablation.
The findings of this study demonstrate that the expression of HIF-2α, VEGFA and EphA2 can be inhibited by sorafenib, and that sorafenib is likely to provide an effective adjunct treatment for patients with HCC following HIFU ablation.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a single-stranded RNA virus that causes coronavirus disease 2019, which spread worldwide immediately after the first patient infected with this virus was discovered in Wuhan, China, in December 2019. Currently, polymerase chain reaction (PCR) specimens for the detection of SARS-CoV-2 include saliva, nasopharyngeal swabs, and lower respiratory tract-derived materials such as sputum. Initially, nasopharyngeal swab specimens were applied mainly to the PCR detection of SARS-CoV-2. There was a risk of infection to healthcare workers due to coughing or sneezing by the subjects at the time of sample collection. In contrast, saliva specimens have a low risk of droplet infection and are easy to collect, and their application to PCR testing has been promoted. In this study, we have determined the detection limit of SARS-CoV-2 in saliva samples and examined the effects of storage temperature and storage time of saliva samples on the PCR detection results. As a result, 5 × 103 copies of SARS-CoV-2 could be detected in 1 mL phosphate-buffered saline, whereas 5 × 104 copies of SARS-CoV-2 were needed in 1 mL saliva to detect the virus by real-time one-step PCR. Interestingly, SARS-CoV-2 (5 × 103 copies/mL) could be detected in saliva supplemented with an RNase inhibitor. Concerning the saliva samples supplemented with an RNase inhibitor, the optimal temperature for sample storage was -20 °C, and PCR detection was maintained within 48 h without problems under these conditions. These finding suggest that RNase in the saliva can affect the detection of SARS-CoV-2 by PCR using saliva samples.Crohn's disease of the pouch (CDP) is seen in a subset of ulcerative colitis (UC) patients following ileal pouch-anal anastomosis (IPAA). Histologic or clinical predictors of CDP are unknown. UC patients with subsequent CDP diagnosis were identified. The rationales for the diagnosis, the interval from the initial signs of CDP to the diagnosis, family history and smoking history were reviewed. Archived pathology materials were reviewed for the presence of pyloric gland metaplasia (PGM) and compared with those from UC with similar severity of pouchitis with CDP (matched UC controls), random UC controls, and ileocolectomies from primary CD patients. CDP diagnosis was made in 26 (18.1%) of 144 patients; all of them met commonly used diagnostic criteria for CDP. The diagnosis was rendered on average 15 months after the initial CD-like signs. PGM was found in 58% of CDP, more common than random UC controls but no different from primary CD and matched UC controls. PGM preceded first signs of CD in a subset. Patients with a family history of CD were more likely to develop CDP than those without a family history of any type of inflammatory bowel disease.
