OBJECTIVE: The implantation of cancer cells in the chest wall after percutaneous needle biopsy of the lung is rare. We investigated the clinical outcomes of implantation metastasis after percutaneous fine-needle aspiration biopsy of pulmonary mass suggestive of lung cancer. METHODS: Between January 1990 and December 2001, nine patients were treated for implantation metastasis of the chest wall. We retrospectively reviewed the patients' records and analyzed their clinical outcomes. RESULTS: Durin

Spinocerebellar ataxia type 1 (SCA1) is a fatal, dominantly inherited neurodegenerative disease caused by the expansion of CAG repeats in the Ataxin-1 (ATXN1) gene. SCA1 is characterized by balance and coordination deficits due to the predominant loss of Purkinje neurons in the cerebellum. We previously demonstrated that cerebellar astrogliosis beings during the early stages of SCA1, prior to onset of motor deficits and loss of Purkinje neurons. We communicate here that cerebellar astrogliosis c

BACKGROUND: The phosphoinositol 3-kinase (PI3K) pathway is associated with poor prognosis of hematologic malignancies, providing a strong rationale for the use of PI3K inhibitors in the treatment of malignant lymphoma. However, development of resistance limits the use of PI3K inhibitors in lymphoma patients. METHODS: We established copanlisib (pan-PI3K inhibitor)-resistant B-cell lymphoma and duvelisib (PI3Kδ and -γ inhibitor)-resistant T-cell lymphoma cell lines. The cytokine array and the phos

Blockage of B cell receptor signaling with ibrutinib presents a promising clinical approach for treatment of B-cell malignancies. However, many patients show primary resistance to the drug or develop secondary resistance. In the current study, cDNA microarray and Western blot analyses revealed CD79B upregulation in the activated B cell-like diffuse large B-cell lymphoma (ABC-DLBCL) that display differential resistance to ibrutinib. CD79B overexpression was sufficient to induce resistance to ibru

Epstein-Barr virus (EBV)-encoded latent membrane protein-1 (LMP1) is a transmembrane protein essential for EBV-induced immortalization and transformation of B cells. Activation-induced cytidine deaminase (AID) triggers somatic hypermutation and recombination, in turn contributing to lymphomagenesis. Here, we report an intracellular mechanism by which LMP1 contributes to B cell lymphomagenesis via AID expression. In our experiments, LMP1 increased AID mRNA expression and promoter activity. The AI

To investigate the effect of Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1) on human cancer cells, we sought to identify and analyze potential target genes that were differentially expressed in the presence and absence of LMP1. Our cDNA microarray analysis revealed that expression of early growth response gene-1 (Egr-1) was increased by LMP1 expression in MCF7 and Jurkat cells. An NFkappaB inhibitor (SN50) antagonized LMP1-induced enhancement of Egr-1 expression, indicating that LMP1

Objective Patient education materials across 3 national English otolaryngology–head and neck surgery (OHNS) societies: the American Academy of Otolaryngology–Head and Neck Surgery (AAO‐HNS), the Canadian Society of Otolaryngology–Head and Neck Surgery (CSOHNS), and Ear, Nose, and Throat United Kingdom (ENT UK) were examined to determine whether they are written at a level suitable for patient comprehension. Study Design Cross‐sectional study. Setting Online patient materials presented through OH

To investigate the effect of Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1) on human cancer cells, we sought to identify and analyse potential target genes that were differentially expressed in the presence and absence of LMP1. LMP1 upregulated the expression of SNARK compared with the empty vector transfected control cells, which was confirmed by reverse-transcription polymerase chain reaction. Cytotoxicity assay showed that SNARK expression increased drug resistance in response to d

An increasing number of pathogenic variants in presynaptic proteins involved in the synaptic vesicle cycle are being discovered in neurodevelopmental disorders. The clinical features of these synaptic vesicle cycle disorders are diverse, but the most prevalent phenotypes include intellectual disability, epilepsy, movement disorders, cerebral visual impairment, and psychiatric symptoms ( Verhage and Sørensen, 2020; Bonnycastle et al., 2021; John et al., 2021; Melland et al., 2021). Among this gro

본 연구는 일반계 고등학교 1학년을 대상으로 진로준비행동 촉진 집단상담 프로그램을 실시하여 진로준비행동, 진로의식, 진로결정자기효능감에 미치는 효과를 확인하는데 그 목적을 두었다. 이러한 목적을 위해 서울특별시 소재 Y고등학교 1학년 학생들 중 프로그램 참여의사를 나타낸 24명을 실험집단, 통제집단, 비교집단에 각각 8명씩 무선배정 하였다. 프로그램 운영은 4주 동안 총 8회기, 한 차시마다 50~90분씩 실시하였다. 실험집단에는 진로준비행동촉진 집단상담 프로그램을 실시했으며, 통제 집단에는 아무런 처치를 가하지 않았고, 비교집단에는 또래상담 프로그램을 4주간 총 8회기를 실시하였다. 프로그램의 효과를 검증하기 위하여 실험, 통제, 비교 집단에 진로준비행동, 진로의식, 진로결정자기효능감 척도를 사전, 사후로 실시하였다. 수집된 자료는 공변량분석(ANCOVA)으로 분석하고, 집단 간 사후검정을 위해 Bonferroni의 다중비교 검정을 실시하였다. 분석 결과, 진로준비행동 촉진 집단상

Saccular cysts can be managed endoscopically using CO2 laser, without requiring an external approach. Therefore, an endoscopic approach should be actively considered for an optimal treatment outcome.

ADM implantation can effectively reduce the occurrence of Frey's syndrome, infra-auricular depressed deformity, and first bite syndrome after parotidectomy. ADM may be especially advantageous in complex parotidectomy cases when significant complications are expected.
