Altogether, these results indicate that Lurbinectedin might have antitumor activity in CLL due to its direct action on leukemic cells in combination with its effects on the tumor microenvironment. Our findings encourage further investigation of Lurbinectedin as a potential therapy for CLL.CD160 is an Ig-like glycoprotein expressed by the majority of circulating natural killer cells and γδ T cells. Whether CD160 could regulate CD8+ T-cell functions remains unknown. In this study, we investigated the effects of CD160 on CD8+ T cells in pancreatic cancer. First, we found that the frequency of PD-1+ cells was comparable between CD160+ and CD160-CD8+ T cells, with the former presenting significantly higher PD-1 expression level. In contrast, the frequency of TIM-3+ cells was higher among CD160+ cells but the expression level was comparable between CD160+ and CD160-CD8+ T cells. The IFN-γ and IL-2-expressing CD8+ T cells, directly ex vivo, were highly enriched in the CD160+ subset. However, when CD160+ and CD160-CD8+ T cells were stimulated, the proliferation levels of CD160+ and CD160- cells were initially comparable, but were significantly lower in CD160+CD8+ T cells than in CD160-CD8+ T cells later on. The IFN-γ and IL-2 transcription levels were initially higher in CD160+CD8+ T cells, but eventually reduced in CD160+CD8+ T cells compared to CD160-CD8+ T cells. Also, CD160+CD8+ T cells presented lower cytotoxic capacity than CD160-CD8+ T cells. Interestingly, we observed that tumor-infiltrating CD8+ T cells were significantly enriched with the CD160+ subset in pancreatic cancer patients. In addition, patients with higher frequencies of tumor CD160+CD8+ T cells presented lower survival. Overall, these data demonstrated that tumor-infiltrating CD8+ T cells were enriched with the CD160+ subset in pancreatic cancer, with active effector responses directly ex vivo but limited potential for further activation.The underlying basis for cancer immune evasion is important for effective immunotherapy and prognosis in breast cancers. Human leucocyte antigens (HLA)-I comprising three classical antigens (HLA-A, -B and -C) is mandatory for anti-tumor immunity. Its loss occurred frequently in many cancers resulting in effective immune evasion. Most studies examined HLA-I as a whole. Alterations in specific locus could have different clinical ramifications. Hence, we evaluated the expression of the three HLA-I loci in a large cohort of breast cancers. Selleckchem Tanshinone I Low expression of HLA-A, -B and -C were found in 71.1%, 66.3%, and 60.2% of the cases. Low and high expression in all loci was found in 48.3% and 17.9% of the cases respectively. The remaining showed high expression in one or two loci. Cases with all HLA high expression (all HLA high) was frequent in the ER-HER2- (27.4%) and ER-HER2+ (23.1%) cases and was associated with characteristic pathologic features related to these tumor (higher grade, necrosis, high tumor infiltrating lymphocyte (TIL), pT stage, low hormonal receptor, high basal marker expression) (p ≤ 0.019). Interestingly, in HER2+ cancers, only cases with all HLA high and high TIL showed significantly better survival. In node positive cancers, concordant high HLA expression in primary tumors and nodal metastases was favorable prognostically (DFS HR = 0.741, p  less then  0.001; BCSS HR = 0.699, p = 0.003). The data suggested an important clinical value of a combined analysis on the co-expression HLA-I status in both primary and metastatic tumors. This could be a potential additional key component to be incorporated into TIL evaluation for improved prognostication.BACKGROUND Few studies on the safety of gadolinium-based contrast agents have been performed in children with even fewer focusing on children younger than 2 years of age. OBJECTIVE To assess the safety of gadoterate meglumine (Dotarem) in patients younger than 2 years of age by evaluating adverse events following contrast administration. MATERIALS AND METHODS Pediatric patients younger than 2 years of age undergoing magnetic resonance imaging (MRI) with and without contrast were prospectively enrolled and received a weight-based intravenous dose of gadoterate meglumine (0.1 mmol/kg). The occurrence of adverse events was assessed at the time of injection, 2 h after MRI, and by phone contact using a standard questionnaire 24 h after MRI. Adverse events were documented including the time of onset, duration of symptoms, intensity, causality and subsequent outcome. Descriptive statistics were used to characterize patient information. RESULTS One hundred fifty exams were completed in 150 patients (median age 12.1 ments were reported to have occurred in the initial 2 h after the exam, while the rest were reported on the 24-h follow-up call. The higher reported rate of adverse events in this study may be related to concomitant sedation/anesthesia as well as to overreporting from parents on the 24-h follow-up questionnaire. The study confirms a good safety profile for gadoterate meglumine in this very sensitive population.Contrast-enhanced ultrasonography (US) has become an important supplementary tool in many clinical applications in children. Contrast-enhanced voiding urosonography and intravenous US contrast agents have proved useful in routine clinical practice. Other applications of intracavitary contrast-enhanced US, particularly in children, have not been widely investigated but could serve as a practical and radiation-free problem-solver in several clinical settings. Intracavitary contrast-enhanced US is a real-time imaging modality similar to fluoroscopy with iodinated contrast agent. The US contrast agent solution is administered into physiological or non-physiological body cavities. There is no definitive list of established indications for intracavitary US contrast agent application. However, intracavitary contrast-enhanced US can be used for many clinical applications. It offers excellent real-time spatial resolution and allows for a more accurate delineation of the cavity anatomy, including the internal architecture of complex collections and possible communications within the cavity or with the surrounding structures through fistulous tracts. It can provide valuable information related to the insertion of catheters and tubes, and identify related complications such as confirming the position and patency of a catheter and identifying causes for drainage dysfunction or leakage. Patency of the ureter and biliary ducts can be evaluated, too. US contrast agent solution can be administered orally or a via nasogastric tube, or as an enema to evaluate the gastrointestinal tract. In this review we present potential clinical applications and procedural and dose recommendations regarding intracavitary contrast-enhanced ultrasonography.In order to foster the potential of exclosures to sequester carbon, it is understood that they are increasingly assisted through enrichment planting. To study the impact of the enrichment planting on carbon sequestration process, five exclosures with enrichment planting and five pure naturally regenerated exclosures were selected. Along parallel transects, 20 × 20 m plots were laid at 100 m intervals where all woody vegetations were counted and measured for their diameter and total height. For soil sampling, five subplots at the center and four at each corner of the plots were established. The samples were collected at a depth of 0-0.2 m, and this procedure was repeated for each plot. In this case, when good management practices were implemented (such as Wukro exclosures), significant differences in organic soil carbon above the ground and the total carbon between naturally regenerated and enriched exclosures (P  less then  0.05) were found. The mean estimates of the above ground carbon, soil carbon, and total carbon were respectively 8.08, 31.04, and 39.12 ton/ha for natural regeneration vs. 7.94, 31.00, and 38.93 ton/ha for enriched regeneration. Lower altitudes had significantly higher soil organic carbon (P  less then  0.05) than the higher altitudes. However, the slope had an insignificant effect on carbon distribution. Enriched exclosures performed more poorly in carbon sequestration. This was possibly due to the disturbances caused by mass plantation and poor post plantation follow up, since improved performance (P  less then  0.05) was seen in one enriched exclosure with better management practices.Community forestry (CF) is increasingly recognized as one of the key solutions to forest management and governance challenges in the developing world. At its heart is the participation of local communities in forest management, bringing multiple benefits in forest health as well as the wellbeing of the local community and the wider society. However, CF in Nepal is felt by many to not be delivering on its potential. This paper presents illustrative examples from a capacity development needs assessment (CDNA), which was conducted to understand challenges CF in Nepal faces, focusing on two districts Rupandehi and Sindhupalchok. The application of the CDNA framework revealed the multiple challenges facing the CF program. They range from lack of multi-stakeholder platform at high level for discussion and resolution of CF-related issues, lack of system to review the program as well as systematic capacity development opportunities for stakeholders and weak governance, altogether contributing to costly and complex process for local community to participate and benefit from the program. We argue that behind these challenges underlie the distrust to local communities and tendency to retain power inequality that is tilted toward techno-bureaucracy, limitation of the program within sectoral boundary of forestry as well as lack of political commitment and overall weak capacity of the status apparatus. We highlight that revitalizing the CF program requires utilization of state restructuring process to expand its scope and improve its governance. Similarly, we emphasize the need for coordinated efforts among stakeholders to relax regulatory burdens, to engage local communities in policy processes, and to set up a capacity development system for supporting community rights mainly in the commercial management of community forests-to ensure that CF delivers.Nitrate accumulation causes long-time threat to aquatic animals in recirculating aquaculture system (RAS); thus, nitrate removal is also required in RASs. However, the lack of carbon sources makes denitrification difficult to function. Nitrate removal performance of an aerobic denitrifying and extracellular polyhydroxyalkanoate depolymerase-producing bacterium, Pseudomonas sp. AOB-7, using polyhydroxyalkanoate (PHA) granules as a solid sustained-release carbon source in RAS was evaluated. With the initial nitrate-N concentration of 140 mg/L, the high denitrification rates of 0.056 g NO3--N L-1 day-1 and 0.035 g NO3--N L-1 day-1 were achieved in denitrification medium containing poly-β-hydroxybutyrate (PHB) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), respectively. Significant erosions and pits formed on the surface of the granules made them a good biofilm carrier for AOB-7, and 3-hydroxybutyrate (3-HB) monomer was the major product released to aquatic phase, which was benefit to animals. SEM photos showed that AOB-7 entered and attached on the inside of the PHA particle holes.
