I demonstrated that the mating-type-altered cells exhibited the same phenotype as those separately generated without MAT gene substitution. This approach can facilitate yeast-strain development and sexual hybridization using available resources with less efforts.<br /><br /> The purpose of the study is to genomically characterize the biology and related therapeutic opportunities of prognostically important predominant histologic subtypes in lung adenocarcinoma (LUAD).<br /><br /> We identified 604 patients with stage I to III LUAD who underwent complete resection and targeted next-generation sequencing using the Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets platform. Tumors were classified according to predominant histologic subtype and grouped by architectural grade (lepidic [LEP], acinar or papillary [ACI/PAP], and micropapillary or solid [MIP/SOL]). Associations among clinicopathologic factors, genomic features, mutational signatures, and recurrence were evaluated within subtypes and, when appropriate, quantified using competing-risks regression, with adjustment for pathologic stage and extent of resection.<br /><br /> MIP/SOL tumors had higher tumor mutational burden (p &lt; 0.001), fraction of genome altered (p= 0.001), copy number amplifications (p= 0.02e results provide the first in-depth assessment of tumor genomic profiling of predominant LUAD histologic subtypes, their associations with recurrence, and their correlation with targetable driver alterations in patients with surgically resected LUAD.<br /><br /> In clinical practice, whether cirrhotic livers in patients with hepatocellular carcinoma (HCC) can withstand repeated stereotactic body radiation therapy (SBRT) remains unclear. This study aimed to evaluate the outcomes and toxicities in these patients.<br /><br /> This retrospective study included patients with HCC who were treated with SBRT at least twice between January 2012 and June 2019. Local control and overall survival rates were calculated. Liver function before and after irradiation was evaluated using the Child-Pugh score and modified albumin-bilirubin grade. All toxicities were assessed using the Common Terminology Criteria for Adverse Events (version 4.0).<br /><br /> Fifty-two patients underwent 136 courses (148 lesions) of SBRT, which was mostly performed for out-of-field tumors but 3 in-field recurrences. The median follow-up duration from the first SBRT was 52.6 months (range, 15.7-89.3 months). The median gross tumor volume was 4.6 cm<br /><br /> (range, 0.8-55.2 cm<br /><br /> ) at the second SBRT. The 3-year local control rate iver dose.<br /><br /> Chordomas are rare, locally malignant tumors derived from remnants of the notochord that can manifest anywhere in the spine or base of the skull. Surgical treatment for chordomas of the lumbar spine often fails to achieve successful en bloc resection, which is critical to minimizing recurrence risk.<br /><br /> In this case report, the authors describe total en bloc resection of a lumbar vertebral body chordoma via the first documented approach of navigated ultrasonic osteotomy for spondylectomy. The patient is a 43-year-old man with end-stage renal disease, requiring dialysis, secondary to diabetes mellitus. The lesion in question was incidentally discovered in the L5 vertebral body during full body scanning for evaluation for a renal transplant. The lesion was diagnosed as a chordoma via percutaneous coaxial needle biopsy.

A combined, staged approach of L3-pelvis posterior instrumented fusion, L5 laminectomy and spondylectomy, and anterior L5 cage reconstruction with L4-S1 fusion was planned. Intraoperative computed tomography scan was performed and stereotactic osteotomies were planned. Ultrasonic osteotome (SONOPET Ultrasonic Aspirator) was registered as a navigation tool and employed, after verification, to complete the posterior stereotactic osteotomies, with postoperative computed tomography, magnetic resonance imaging, and pathology demonstrating successful en bloc resection. The navigated osteotome provided a critical combination of surgical precision and efficiency intraoperatively.<br /><br /> This approach offers a promising technological adjunct for the treatment of complex spine tumors requiring precise resection and reconstruction.<br /><br />This approach offers a promising technological adjunct for the treatment of complex spine tumors requiring precise resection and reconstruction.<br /><br /> Neurosurgical spine specialists receive considerable amounts of industry support that may impact the cost of care. The aim of this study was to evaluate the association between industry payments received by spine surgeons and the total hospital and operating room (OR) costs of an anterior cervical discectomy and fusion (ACDF) procedure among Medicare beneficiaries.<br /><br /> All ACDF cases were identified among the Medicare carrier files from January 1, 2013, to December 31, 2014, and matched to the Medicare inpatient baseline file. The total hospital and OR charges were obtained for these cases. Charges were converted to cost using year-specific cost-to-charge ratios. Surgeons were identified among the Open Payments database, which is used to quantify industry support. Analyses were performed to examine the association between industry payments received and ACDF costs.<br /><br /> Matching resulting in the inclusion of 2209 ACDF claims from 2013-2014. In 2013 and 2014, the mean total cost for an ACDF was $21,798 and $21,008, respectively; mean OR cost was $5878 and $6064, respectively. Mann-Whitney U test demonstrated no significant differences in the mean total or OR cost for an ACDF based on quartile of general industry payment received (P= 0.21 and P= 0.54), and linear regression found no association between industry general payments, research support, or investments on the total hospital cost (P= 0.41, P= 0.13, and P= 0.25, respectively), or OR cost for an ACDF (P= 0.35, P= 0.24, and P= 0.40, respectively).<br /><br /> This study suggests that spine surgeons performing ACDF surgeries may receive industry support without impacting the cost of care.<br /><br />This study suggests that spine surgeons performing ACDF surgeries may receive industry support without impacting the cost of care.
