Liver transplantation: an unfinished product.

Liver transplantation has become an extraordinarily valuable and useful operation, but one that is not perfect and that has not been exploited to anything like its full potential. Better immunosuppression may become available soon as exemplified by developments with the Japanese drug, FK506. Improved preservation with the UW solution is already here. With these advantages, liver transplantation is certain to become far more widely used than at any time in the past. Examples were cited of innovative approaches using liver transplantation for the treatment of hepatic malignancies

Exploring Software Developers’ Experiences in Startups: The Philippine

Though there may be a proliferation of technology startups, it is a sad fact that most of them fail. Because startups depend on people, there is a need to study not only the factors that lead to the success or failure of these startups, but also the experiences of the people on which these startups depend. This study explores the experiences of software developers in technology startups in the Philippines, a developing country that has consistently ranked highly in the annual Tholons Top Outsourcing Destinations Ranking and the Kearney Global Services Location Index. Thematic analysis of interview data revealed 7 themes: Startups are characterized by (1) Rapid Search, which refers to the need to look for or develop something innovative and useful under time pressure. Rapid Search in turn requires a lot of (2) Feedback, highly flexible (3) Development Strategies, a high degree of (4) Collaboration, and a lot of (5) Learning. To cope well with all the uncertainties that startups must face, startup software developers’ (6) Motivations are more intrinsic than extrinsic, and are derived from a strong sense of (7) Community, from all the Learning (theme 5) that the software developer makes because he or she must, and from the internal gratification of having found or developed something innovative and useful, i.e., Rapid Search, which is theme 1

THE LEARNING ENVIRONMENT OF A FAR-FLUNG NATIONAL HIGH SCHOOL: STAKEHOLDERS’ PERSPECTIVE

This study explored the learning environment of a rural public national high school in the Municipality of Don Marcelino, Province of Davao Occidental using a qualitative phenomenological research design. Forty (40) purposively selected participants from the different stakeholders like the students, teachers, parents, and members of the Local Government Unit, and only one (1) participant for the school head underwent an In-Depth Interview and Focused Group Discussion using a semi-structured interview guide/protocol. Data collected were analyzed with the data reduction approach, Thematic Analysis, and Patton's directions. Results revealed the following emergent themes on the learning environment of a far-flung school: Improving school setting amenable to learning; Inadequate proficient teaching force; Insufficient instructional technology; Deficient classroom facilities; and distinctly average academic outcomes. More so, stakeholders addressed challenges through Self-motivation and academic resourcefulness; Aiming high with Faith in the Divine; creating a positive learning atmosphere through Homerooms and Home Visits; Using best pedagogies to motivate learners; Collaborating with stakeholders and getting parents involved; and Coordinating school, community, and LGU. Shared insights of the stakeholders were: Addressed the pandemic challenges; Showed academic value despite modular learning difficulty; Improved teachers' proficiency and classroom scaffolding; Kept learning support mechanism; Sustained parents' support for learners; and Unified medium of instruction. The implications of the study were presented.  Article visualizations

Evidence for hyperacute rejection of human liver grafts: The case of the canary kidneys

Sequential liver and kidney transplantation from the same donor was performed in 2 patients. The kidney in Patient 1, which was transplanted after the liver, was hyperacutely rejected and removed 6 hours later. The first liver as well as another liver transplanted 3 days later developed widespread hemorrhagic necrosis. Although the cytotoxic crossmatch of preoperative recipient serum with both donors was negative, patchy widespread IgM and C(1q) deposits were found in all 3 organs. In Patient 2, who had a strongly positive cytotoxic crossmatch with his donor, the liver suffered a massive but reversible injury, while the kidney never functioned. Both patients developed a coagulopathy a few minutes after liver revascularization. The kidneys in these cases had served like the canaries which miners once used to detect a hostile environment and their presence made more understandable how an indolent version of hyperacute rejection of the liver can take place

‘Advocacy groups are the connectors’: Experiences and contributions of rare disease patient organization leaders in advanced neurotherapeutics

Introduction: Biomedical progress has facilitated breakthrough advanced neurotherapeutic interventions, whose potential to improve outcomes in rare neurological diseases has increased hope among people with lived experiences and their carers. Nevertheless, gene, somatic cell and other advanced neurotherapeutic interventions carry significant risks. Rare disease patient organizations (RDPOs) may enhance patient experiences, inform expectations and promote health literacy. However, their perspectives are understudied in paediatric neurology. If advanced neurotherapeutics is to optimize RDPO contributions, it demands further insights into their roles, interactions and support needs. Methods: We used a mixed-methodology approach, interviewing 20 RDPO leaders representing paediatric rare neurological diseases and following them up with two online surveys featuring closed and open-ended questions on advanced neurotherapeutics (19/20) and negative mood states (17/20). Qualitative and quantitative data were analysed using thematic discourse analysis and basic descriptive statistics, respectively. Results: Leaders perceived their roles to be targeted at educational provision (20/20), community preparation for advanced neurotherapeutic clinical trials (19/20), information simplification (19/20) and focused research pursuits (20/20). Although most leaders perceived the benefits of collaboration between stakeholders, some cited challenges around collaborative engagement under the following subthemes: conflicts of interest, competition and logistical difficulties. Regarding neurotherapeutics, RDPO leaders identified support needs centred on information provision, valuing access to clinician experts and highlighting a demand for co-developed, centralized, high-level and understandable, resources that may improve information exchange. Leaders perceived a need for psychosocial support within themselves and their communities, proposing that this would facilitate informed decision-making, reduce associated psychological vulnerabilities and maintain hope throughout neurotherapeutic development. Conclusion: This study provides insights into RDPO research activities, interactions and resource needs. It reveals a demand for collaboration guidelines, central information resources and psychosocial supports that may address unmet needs and assist RDPOs in their advocacy. Patient or Public Contribution: In this study, RDPO leaders were interviewed and surveyed to examine their perspectives and roles in advanced neurotherapeutic development. Some participants sent researchers postinterview clarification emails regarding their responses to questions

Whole-Genome Sequencing and RNA-Seq Reveal Differences in Genetic Mechanism for Flowering Response between Weedy Rice and Cultivated Rice

Flowering is a key agronomic trait that influences adaptation and productivity. Previous studies have indicated the genetic complexity associated with the flowering response in a photoinsensitive weedy rice accession PSRR-1 despite the presence of a photosensitive allele of a key flowering gene Hd1. In this study, we used whole-genome and RNA sequencing data from both cultivated and weedy rice to add further insights. The de novo assembly of unaligned sequences predicted 225 genes, in which 45 were specific to PSRR-1, including two genes associated with flowering. Comparison of the variants in PSRR-1 with the 3K rice genome (RG) dataset identified unique variants within the heading date QTLs. Analyses of the RNA-Seq result under both short-day (SD) and long-day (LD) conditions revealed that many differentially expressed genes (DEGs) colocalized with the flowering QTLs, and some DEGs such as Hd1, OsMADS56, Hd3a, and RFT1 had unique variants in PSRR-1. Ehd1, Hd1, OsMADS15, and OsMADS56 showed different alternate splicing (AS) events between genotypes and day length conditions. OsMADS56 was expressed in PSRR-1 but not in Cypress under both LD and SD conditions. Based on variations in both sequence and expression, the unique flowering response in PSRR-1 may be due to the high-impact variants of flowering genes, and OsMADS56 is proposed as a key regulator for its day-neutral flowering response

Numerical study of a thrombus migration risk in aneurysm after coil embolization in patient cases: FSI modelling

Purpose There are still many challenges for modelling a thrombus migration process in aneurysms. The main novelty of the present research lies in the modelling of aneurysm clot migration process in a realistic cerebral aneurysm, and the analysis of forces sufered by clots inside an aneurysm, through transient FSI simulations. Methods The blood fow has been modelled using a Womersley velocity profle, and following the Carreau viscosity model. Hyperelastic Ogden model has been used for clot and isotropic linear elastic model for the artery walls. The FSI coupled model was implemented in ANSYS® software. The hemodynamic forces sufered by the clot have been quantifed using eight diferent clot sizes and positions inside a real aneurysm. Results The obtained results have shown that it is almost impossible for clots adjacent to aneurysm walls, to leave the aneurysm. Nevertheless, in clots positioned in the centre of the aneurysm, there is a real risk of clot migration. The risk of migration of a typical post-coiling intervention clot in an aneurysm, in contact with the wall and occupying a signifcant percentage of its volume is very low in the case studied, even in the presence of abnormally intense events, associated with sneezes or impacts. Conclusions The proposed methodology allows evaluating the clot migration risk, vital for evaluating the progress after endovascular interventions, it is a step forward in the personalized medicine, patient follow-up, and helping the medical team deciding the optimal treatment.Universidade de Vigo/CISU

Exploring the institutional market for fresh vegetables in the Southern Philippines

Given the many different ways the product may be used, the institutional market for fresh vegetables in the Southern Philippines can be segmented on the basis of the role market intermediaries perform in the supply chain, where they are, what customers they serve, the range of products required, the volume of product required and the quality specifications. Potential market opportunities are identified and the various constraints smallholder farmers face in endeavouring to meet the needs of institutional buyers are highlighted

Socio-economic impact of cluster marketing: The case of Ned Landcare Association sweet pepper cluster

Through clustering, opportunities exist for smallholder farmers to organize their output and to sell directly to institutional markets. This paper analyses the experiences of the cluster marketing approach in Barangay Ned, Lake Sebu, South Cotabato. The case demonstrates how farmers in the cluster group developed an enterprise plan, established linkages with a microfinance institution and negotiated sales to downstream market intermediaries. Farmers in the cluster increased their technical and marketing knowledge, improved their farming and marketing practices, improved their access to capital and increased their income. Trust, confidence, commitment and unity among cluster members were established through the cluster marketing approach
