Structural and functional characterization of a thermostable secretory phospholipase A from Sciscionella marina and its application in liposome biotransformation.

Secretory phospholipase A (sPLA), which hydrolyzes the sn-2 acyl bond of lecithin in a Ca-dependent manner, is an important enzyme in the oil and oleochemical industries. However, most sPLAs are not stable under process conditions. Therefore, a thermostable sPLA was investigated in this study.

Valorization of Soy Lecithin by Enzyme Cascade Reactions Including a Phospholipase A2, a Fatty Acid Double-Bond Hydratase, and/or a Photoactivated Decarboxylase.

A huge amount of phospholipids or lecithin is produced as a byproduct in the vegetable oil industry. However, most are just used as a feed additive. This study has focused on enzymatic valorization of lecithin.

Care Needs of Adolescents and Young Adults with Cancer Undergoing Active Treatment in South Korea: A Mixed Methods Study.

Adolescents and young adults (AYAs) with cancer have special care needs that are different from those of children and older adults with cancer. This study assessed the perspective and experience of AYAs with cancer in South Korea to identify their care needs. This study used a convergent mixed-methods design.

Paediatric palliative screening scale as a useful tool for clinicians' assessment of palliative care needs of pediatric patients: a retrospective cohort study.

Background: Although the importance of palliative care in pediatric patients has been emphasized, many health care providers have difficulty determining when patients should be referred to the palliative care team. The Paediatric Palliative Screening Scale (PaPaS) was developed as a tool for screening pediatric patients for palliative care needs. The study aimed to evaluate the PaPaS as a reliable tool for primary care clinicians unfamiliar with palliative care.

Increasing and worsening late effects in childhood cancer survivors during follow-up.

Recent advances in childhood cancer treatment have increased survival rates to 80%. Two out of three survivors experience late effects (LEs). From a group of 241 survivors previously described, 193 were followed at the long-term follow-up clinic (LTFC) of Severance Hospital in Korea; the presence of LEs was confirmed by oncologists.

Two cases of Wernicke's encephalopathy in young age patients receiving allogeneic hematopoietic stem cell transplantation.

Wernicke's encephalopathy is an acute neurolopsychiatric syndrome caused by thiamine deficiency, and classically presents with the triad of opthalmopathy, ataxia and altered mentality. Both prolonged total parenteral nutrition and reduced oral intake can induce Wernicke's encephalopathy during hematopoietic stem cell transplantation (HSCT). Although early treatment is important for recovery from Wernicke's encephalopathy, the vague symptoms and characteristics hinder early diagnosis.

Feasibility of sequential high-dose chemotherapy in advanced pediatric solid tumors.

The purpose of this study was to evaluate the feasibility and tumor response of 3 cycles of sequential high-dose chemotherapy (HDCT) in advanced pediatric solid tumor patients. Medical records of 11 children who underwent 2 consequent courses of reduced conditioning HDCT followed by final HDCT with autologous HSC infusion were reviewed in a retrospective manner. Each median time to an absolute neutrophil count > 0.

Posterior reversible encephalopathy syndrome in childhood with hematologic/oncologic diseases.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiologic disease entity represented by characteristic magnetic resonance image (MRI) findings of subcortical/cortical hyperintensity in T2-weighted sequences, more often observed in parieto-occipital lobes, accompanied by clinical neurologic alterations. PRES is a rare central nervous system complication in childhood hematologic-oncologic patients and shows very different neurologic symptoms between patients, from numbness on extremities to generalized seizure. The etiology of PRES was not well known until these days.

Acute interstitial pneumonia in siblings: a case report.

Acute interstitial pneumonia (AIP) is a rapidly progressive condition of unknown cause that occurs in a previously healthy individual and produces the histologic findings of diffuse alveolar damage. Since the term AIP was first introduced in 1986, there have been very few case reports of AIP in children. Here we present a case of AIP in a 3-yr-old girl whose other two siblings showed similar radiologic findings.

A good outcome for a case of chronic pneumonitis of infancy.

Chronic pneumonitis of infancy (CPI) is a very rare interstitial lung disease. Its pathological features differ from other types of interstitial pneumonia that occur in adults and children. The mortality rate of CPI is high, even with treatment.

Autologous peripheral blood stem cell transplantation in children with non-Hodgkin's lymphoma: A report from the Korean society of pediatric hematology-oncology.

Recent development of stratified chemotherapeutic regimens has rapidly improved the survival rate of non-Hodgkin's lymphoma (NHL) of childhood. Despite these improvements, the outcome for children with recurrent or refractory NHL remains dismal. We explored the use of high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (HDC/PBSCT) for children with either refractory or recurrent NHL, and we evaluated various factors influencing outcome of HDC/PBSCT.
