nes with more highly differentiated expression patterns are more likely to be retained as duplicates than those with more conserved expression profiles. Phenotype of Arabidopsis thaliana mutants showed that loss of genes with a greater tendency to be retained after duplication resulted in more severe growth deficiency. CaCAs genes in salt-tolerant species tended to inherit the expression characteristics of their most recent common ancestral genes, with conservative ion-response expression. This study indicates a possible evolutionary scheme for cation transport and illustrates distinct fates and a mechanism for the evolution of gene duplicates. The increased copy numbers of genes and divergences in expression might have contributed to the divergent functions of CaCAs protein, allowing plants to cope with environmental stresses and adapt to a larger number of ecological niches.

Biliary tract obstruction in cancer patients is usually associated with a poor prognosis. The obstruction may cause distressing symptoms, such as pruritus. As this situation occurs mostly in advanced cancer, the primary objective of the treatment is in many cases symptom control and not prolonging life. However, some patients can be candidates for chemotherapy. To see the outcomes of stenting insertion in patients of our oncology center.

A retrospective study of patients who have undergone this procedure between 1 October 2011 and 31 December 2018 was carried out.

Insertion of a biliary stent was performed in 171 patients. The most common diagnoses were gastric and colorectal cancers, each with 42 (24%), followed by pancreatic (34 (20%)) and biliary tract cancer (25 (14%)). Most stents (155 (91%)) were placed percutaneously. Complications were seen in 91 (53%) patients and the most common was cholangitis in 48 (53%) patients, and the median survival was 75.5 days (3-1246). A total of 168 (98%) patients were referred to palliative care. In a multivariable analysis, the ECOG performance status was associated with survival, with the ECOG 0, 1, and 2 associated with better survival and peritoneal metastases associated with lower survival.

For many patients with advanced cancers, it may not be clear if the benefits of palliative biliary stents outweigh the risks. Therefore, the problem should be discussed with the patients and their families, making clear the goals of care and the potential benefits and risks that can be expected.

There are various methods of decellularization without a standard protocol. Detergents approaches are simple, and easy control of experimental conditions. Non-ionic detergent Triton X-100 and ionic detergent sodium dodecyl sulfate (SDS) are the most commonly used detergents. In this study, we used Triton X-100 and SDS with different concentrations to decellularize porcine carotid arteries. After that, we investigated the acellular effect and mechanical properties of decellularized arteries to find a promising concentration combination for decellularization. Results showed that any detergents' combination would damage the inherent structure of extracellular matrix, and the destruction increased with the increase of detergents' concentration. We concluded that the decellularization approach of 0.5% Triton X-100 for 24 h combined with 0.25% SDS for 72 h could help to obtain decellularized arteries with minimum destruction. This protocol may be able to prepare a clinically suitable vascular scaffold for TEVGs.The automated detection technique becomes the inexorable trend of medical development of the world. The objective of the work is to explore a feasible approach for patient-specific seizure detection in long-term electroencephalogram (EEG) recordings. For this purpose, a novel method based on nonlinear mode decomposition (NMD) has been proposed in this study. A sliding window is used on the multi-channel EEG, where four selected channels have been segmented into a series of successive short epochs with a 2-s duration. Then, the EEG is decomposed into a set of nonlinear modes (NMs) by the NMD algorithm and one type of statistical parameter named fractional central moment (FCM) is calculated over the first two NMs constituting the input feature vector to be fed to three common classifiers. The proposed features, when using K nearest neighbor (KNN), are able to detect seizures with high sensitivity values across all patients consistently. We have explored the ability of the FCM in NMD domain for classification of seizure and non-seizure EEG signals. Our approach has achieved the average sensitivity, specificity, and accuracy values as 98.40%, 99.10%, and 98.61%, respectively, over all the data groups on CHB-MIT database. The experimental results have indicated that the proposed method is not only quite reliable in diagnosing seizure with single type of feature yielding satisfied performance but also robust to variations of seizure types among patients. In this regard, it can be expected that our proposed method is endowed with promising prospects for the use of an expert software application in real-time automated seizure detection. Graphical abstract.C60 is a potent antioxidant that has been reported to substantially extend the lifespan of rodents when formulated in olive oil (C60-OO) or extra virgin olive oil (C60-EVOO). Despite there being no regulated form of C60-OO, people have begun obtaining it from online sources and dosing it to themselves or their pets, presumably with the assumption of safety and efficacy. Brincidofovir in vivo In this study, we obtain C60-OO from a sample of online vendors, and find marked discrepancies in appearance, impurity profile, concentration, and activity relative to pristine C60-OO formulated in-house. We additionally find that pristine C60-OO causes no acute toxicity in a rodent model but does form toxic species that can cause significant morbidity and mortality in mice in under 2 weeks when exposed to light levels consistent with ambient light. Intraperitoneal injections of C60-OO did not affect the lifespan of CB6F1 female mice. Finally, we conduct a lifespan and health span study in males and females C57BL/6 J mice comparing oral treatment with pristine C60-EVOO and EVOO alone versus untreated controls. We failed to observe significant lifespan and health span benefits of C60-EVOO or EVOO supplementation compared to untreated controls, both starting the treatment in adult or old age. Our results call into question the biological benefit of C60-OO in aging.

This study aims to assess the feasibility and impact on long-term pulmonary function of chest drain removal on the operation day following thoracoscopic right upper lobectomy for clinical stage I non-small cell lung cancer.

We retrospectively evaluated the data of 116 patients between May 2013 and March 2019. We evaluated the correlations of clinical parameters of chest drain removal and medium- and long-term pulmonary function by comparing removal on operation day (R group) and retainment (D group).

The R group comprised 64 patients, and the D group had 52 patients. Fifty patients (96.2%) in the D group had chest drain removed within 3 postoperative days. Since February 2016, chest drain removal on operation day was performed in 64 of 74 patients (86.5%) according to our chest drain removal protocol. Removal of chest drains on operation day was associated with shorter postoperative hospitalization (p < 0.01) and lower postoperative complications ≧ grade II of the Clavien-Dindo classification (p = 0.026). Only one patient in the R group needed reinsertion. The R group had greater spirometry results at 3- and 12-postoperative months (POM). R group patients had statistically improved pulmonary functions from 3 to 12POM, while those in the D Group were stagnated at 6POM.

Removal of chest drains on operation day using our protocol is safe and feasible for thoracoscopic right upper lobectomy. This protocol was statistically associated with slightly better long-term pulmonary function, which could not bring clinically meaningful medium- and long-term benefit.

In the surgical field, patient-specific organ models are increasingly being used as preoperative simulators for complicated surgeries. In this study, we describe the use of patient-specific 3D models for tracheal resection. We performed preoperative simulations for two patients diagnosed with tracheal ganglioneuroma and adenoid cystic carcinoma; the mimic operations suggested the necessity of a short cuff intubation tube across the surgical field, indicating the recommended amount of dissection around the trachea and bilateral hilum prior to tracheal reconstruction. The postoperative courses were free from any anastomotic or pulmonary complications. We described the availability of preoperative simulations for complicated tracheal resection and reconstruction using patient-specific 3D printed models. Mimic operations using the 3D printed models allowed accurate preparation and confidence in selection of the optimal surgical strategy.

Since the end of 2019, dialysis patients have been at risk of coronavirus disease 2019 (COVID-19) as well as other potential complications. Hence, we sought to describe the clinical characteristics of dialysis patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

We reviewed clinical outcomes, which consisted of clinical data extracted from the medical records of 695 registered dialysis patients at the Dialysis Center of Central Hospital of Wuhan from January 13th, 2020, to February 29th, 2020, and performed statistical analysis. According to the results, there were 447, 227 and 21 hemodialysis (HD), peritoneal dialysis (PD) and combined HD and PD (HD&PD) cases, respectively.

During the outbreak of COVID-19, 36 dialysis patients were infected by SARS-CoV-2. Among those 36 patients, 32 (7.2%) were on HD, and 4 (1.8%) were on PD. When comparing SARS-CoV-2 infection between HD and PD, the relative risk was 4.07 (RR = 4.07, 95% CI 1.46-11.35). We noted a median age of 66years during the observation period, and the number of male patients was 23 (63.9%). There were 15 fatal cases tested positive for SARS-CoV-2 (13 cases on HD and 2 cases on PD). By comparing mortality in the same period of 2018, 2019 and 2020, the all-cause mortality of hemodialysis patients was significantly higher in 2020 (4.89%) than in either 2018 (2.55%) or 2019 (1.97%). There was no significant difference in mortality from all causes excluding COVID-19, during the same period among the 3-year period. However, during the COVID-19 outbreak, the mortality from all causes excluding COVID-19 was 2.73%, which was slightly higher than that from COVID-19 (2.16%).

Although COVID-19 seriously threatens the health of people with uremia, deaths from all causes excluding COVID-19 during the epidemic cannot be ignored.
