Macrophage-like Blood Cells Are Involved in Inter-Tissue Communication to Activate JAK/STAT Signaling, Inducing Antitumor Turandot Proteins in Fat Body via the TNF-JNK Pathway.

Turandot (Tot) family proteins, which are induced via the JAK/STAT pathway after infection, also suppress lymph gland tumors in mutant larvae. We investigated the potential role of hemocytes in induction in tumor-bearing mutants via immunostaining and RNAi experiments. Normal hemocytes transplanted into mutant larvae were recruited to the tumor and fat body (FB), suggesting that these cells transmit tumor-related information.

Efficacy of Oral Sirolimus Therapy for Adult Orbital Slow-Flow Vascular Malformations: A Volumetric Evaluation.

Orbital lymphatic malformations significantly impair visual function, with inflammation contributing to corneal dryness and diplopia due to exophthalmos. Disease progression may lead to blindness, and in severe cases, exenteration may be required. We treated two symptomatic cases of adult orbital slow-flow vascular malformations with oral sirolimus.

Thermal Adaptations in Animals: Genes, Development, and Evolution.

Thermal adaptation to environmental temperature is a driving force in animal evolution. This chapter presents thermal adaptation in ectotherms and endotherms from the perspective of developmental biology. In ectotherms, there are known examples of temperature influencing morphological characteristics, such as seasonal color change, melanization, and sex determination.

Glycogenolysis-Induced Astrocytic Serping1 Expression Regulates Neuroinflammatory Effects on Hippocampal neuron.

The bacterial pathogen, lipopolysaccharide (LPS), elicits microglial response and induces cytokine secretion that subsequently activates astrocytes. Recent findings have indicated that LPS-induced activation of postnatal glial cells has led to alterations in synapse formation in hippocampal and cortical neurons, thereby resulting in a prolonged increased risk for seizure or depression. Nevertheless, its mechanisms remain to be fully elucidated.

Oncological Outcomes of Concurrent Chemoradiotherapy and Surgical Treatment for Patients With T3 Hypopharyngeal Cancer: A Single-Center Retrospective Analysis.

Background Since the larynx and pharynx are vital for respiration, swallowing, and speech, chemoradiotherapy (CRT) has been widely applied for T3 hypopharyngeal cancer (HPC) as an organ-preserving treatment. However, CRT can lead to severe late adverse events such as dysphagia and aspiration pneumonia, especially in patients who have difficulty swallowing and/or aspiration at the time of initial diagnosis. Patients and methods Between 2012 and 2020, 86 patients with T3 HPC treated with curative intent at Kobe University Hospital were included in this study.

Salvage surgery for mesenteric lymph node metastasis by resection of the first jejunal flap and reconstruction with the second jejunal flap.

We report a case of a second free jejunal transfer to treat metastasis in the mesenteric lymph node of the first jejunal flap. A 73-year-old man underwent total pharyngolaryngectomy, bilateral neck dissection, and free jejunal transfer for recurrent hypopharyngeal cancer [left pyriform sinus, pT2N0, moderately differentiated squamous cell carcinoma (SCC)] after radiotherapy. Seven years post-surgery, he underwent transoral videolaryngoscopic surgery for oropharyngeal cancer (soft palate, pT1N0, well-differentiated SCC).

A Neanderthal/Denisovan GLI3 variant contributes to anatomical variations in mice.

Changes in genomic structures underlie phenotypic diversification in organisms. Amino acid-changing mutations affect pleiotropic functions of proteins, although little is known about how mutated proteins are adapted in existing developmental programs. Here we investigate the biological effects of a variant of the GLI3 transcription factor (GLI3) carried in Neanderthals and Denisovans, which are extinct hominins close to modern humans.

A Clinical Study of Histopathological and Clinical Image Changes After Sclerotherapy of Lip Venous Malformations.

Venous malformations (VMs) are histopathologically benign but can greatly impair patients' quality of life. Screlothprapy is known to be effective in improving symptoms without a scar, but surgical resection of residual lesions is sometimes necessary due to inadequate reduction. However, there is no consensus on what criteria should be used to consider switching to surgical treatment, and individualized decisions must be made for each case.

Vasodilating Effects of Antispasmodic Agents and Their Cytotoxicity in Vascular Smooth Muscle Cells and Endothelial Cells-Potential Application in Microsurgery.

This study aimed to elucidate the vasodilatory effects and cytotoxicity of various vasodilators used as antispasmodic agents during microsurgical anastomosis. Rat smooth muscle cells (RSMCs) and human coronary artery endothelial cells (HCAECs) were used to investigate the physiological concentrations and cytotoxicity of various vasodilators (lidocaine, papaverine, nitroglycerin, phentolamine, and orciprenaline). Using a wire myograph system, we determined the vasodilatory effects of each drug in rat abdominal aortic sections at the concentration resulting in maximal vasodilation as well as at the surrounding concentrations 10 min after administration.

Absorbable Barbed Continuous versus Nonabsorbable Nonbarbed Interrupted Suturing Methods for Donor-site Closure of the Rectus Abdominis Myocutaneous Flap.

Unlabelled: Abdominal incisional hernia is a complication of the rectus abdominis myocutaneous (RAMC) flap harvest. This study aimed to compare the incidence of abdominal incisional hernia and donor-site closure time between absorbable barbed continuous (ABC) and non-absorbable non-barbed interrupted (nAnBI) methods.

Methods: This study included 145 patients who underwent free RAMC flap reconstruction after head and neck cancer surgery at Kobe University Hospital between January 2012 and March 2020.

Ultrastructural characteristics of oligodendrocyte precursor cells in the early postnatal mouse optic nerve observed by serial block-face scanning electron microscopy.

Oligodendrocyte precursor cells (OPC) arise from restricted regions of the central nervous system (CNS) and differentiate into myelin-forming cells after migration, but their ultrastructural characteristics have not been fully elucidated. This study examined the three-dimensional ultrastructure of OPCs in comparison with other glial cells in the early postnatal optic nerve by serial block-face scanning electron microscopy. We examined 70 putative OPCs (pOPC) that were distinct from other glial cells according to established morphological criteria.

Palliative Free Flap Surgery for Plantar Sarcoma: A Case Report and Literature Review.

We report a case of palliative surgery in a 73-year-old patient with metastatic plantar sarcoma. The patient underwent resection and irradiation of an undifferentiated spindle cell sarcoma in the right plantar region. The wound was not closed and systemic metastases were observed.

A new clinical classification and reconstructive strategy for post-sternotomy surgical site infection.

Introduction: Post-sternotomy surgical site infection (SSI) is a serious complication of cardiovascular surgery. Here, we proposed a new clinical classification and reconstructive strategy for this condition.

Methods: A retrospective study based on medical records was performed on 100 consecutive cases requiring wound management by plastic surgeons for post-sternotomy SSI at Kobe University Hospital between January 2009 and December 2021.

Disruption of the anterior commissure in Olig2 deficient mice.

In the present study, we examined neural circuit formation in the forebrain of the Olig2 knockout (Olig2-KO) mouse model and found disruption of the anterior commissure at the late foetal stage. Axon bundles of the anterior commissure encountered the wall of the third ventricle and ceased axonal extension. L1-CAM immunohistochemistry showed that Olig2-KO mice lose decussation formation in the basal forebrain.

Efficacy of a High-definition Three-dimensional Exoscope in Simultaneous Transcranial and Endoscopic Endonasal Surgery: A Case Report.

Owing to recent advances in medical optical technology, a high-definition (4K) three-dimensional (3D) exoscope has been developed as an alternative tool to using conventional microscopes for microscopic surgery, and its efficacy for neurosurgery has been reported. We report a case who underwent simultaneous surgery aiming for en bloc resection of an anterior skull base malignancy with concurrent exoscopic transcranial and endoscopic endonasal approaches using a 4K 3D exoscope. The patient was a 76-year-old woman who underwent en bloc resection for an anterior skull base olfactory neuroblastoma 13 years ago.

STAT3 transcriptionally regulates the expression of genes related to glycogen metabolism in developing motor neurons.

Motor neurons in the spinal cord are essential for movement. During the embryonic period, developing motor neurons store glycogen to protect against hypoglycemic and hypoxic stress. However, the mechanisms by which glycogen metabolism is regulated in motor neurons remain unclear.

Analysis of Orbital Blowout Fracture Location and Hess Area Ratio.

This study aimed to analyze the Hess area ratio (HAR%) in cases of blowout fracture treated in our department and clarify the outline of eye movement disorders in blowout fractures. Patients who underwent surgery for orbital blowout fractures in our department were included. Fracture locations were classified into 5 types (A, outside floor; B, C, anterior and posterior floor; and D, E, anterior and posterior medial wall).

Combined treatment using cross-leg free flap and the Masquelet technique: a report of two cases.

We introduce a treatment that combines the cross-leg free flap with the Masquelet technique and describe two cases using this method for bone and soft tissue reconstruction. Both patients were successfully treated and ambulatory. This novel method can be safely performed using the delay technique, indocyanine-green angiography and near-infrared spectroscopy.
