The subtle scaphoid fracture in childhood: A case report with literature insights.

We describe a 9-year-old male who suffered a linear, non-displaced scaphoid fracture following a pedestrian motor vehicle accident. Initially, X-ray imaging failed to detect the fracture, but MRI confirmed the diagnosis, highlighting the challenges in identifying scaphoid fractures in pediatric patients due to the bone's cartilaginous nature in this age group. The patient was treated with immobilization using a Plaster of Paris cast, consistent with standard management for non-displaced fractures in children.

Cohen Syndrome With Complex Medical Complications: A Case Report.

Cohen syndrome (CS) is a rare autosomal recessive disorder marked by developmental delays, distinct facial features, and a variety of systemic manifestations. We present a case of a 28-year-old male previously misdiagnosed with Prader-Willi syndrome who exhibited recurrent generalized weakness, fever, fatigue, and significant hemoglobin drops requiring multiple blood transfusions due to thalassemia major. The patient displayed characteristic CS features, including developmental delays, distinct facial characteristics, morbid obesity, and heterochromia iridis.

Chaperonin containing TCP-1 (CCT/TRiC) is a novel therapeutic and diagnostic target for neuroblastoma.

Chaperonin containing TCP1 (CCT/TRiC) is a multi-subunit protein folding complex that enables the cancer phenotype to emerge from the mutational landscape that drives oncogenesis. We and others linked increased expression of CCT subunits to advanced tumor stage and invasiveness that inversely correlates with cancer patient outcomes. In this study, we examined the expression of the second CCT subunit, CCT2, using genomic databases of adult and pediatric tumors and normal tissues, and found that it was highly expressed in pediatric cancers, showing a significant difference compared to normal tissues.

Chaperonin containing TCP1 as a marker for identification of circulating tumor cells in blood.

Herein we report the use of Chaperonin-Containing TCP-1 (CCT or TRiC) as a marker to detect circulating tumor cells (CTCs) that are shed from tumors during oncogenesis. Most detection methods used in liquid biopsy approaches for enumeration of CTCs from blood, employ epithelial markers like cytokeratin (CK). However, such markers provide little information on the potential of these shed tumor cells, which are normally short-lived, to seed metastatic sites.

A single-stage computer-guided gap arthroplasty with simultaneous patient-specific total joint replacement with a novel flat fossa design: A case report.

Introduction And Importance: The computer-guided approach for the patient-specific TMJ replacement is considered an ultimate reliable option in advanced cases. However, dislocation of the condylar head could happen with the concave fossa design. A flat design was described and used in this case.

Identification of a novel IL-5 signaling pathway in chronic pancreatitis and crosstalk with pancreatic tumor cells.

Background: While inflammation is associated with pancreatic cancer, the underlying mechanisms leading to cancer initiation are still being delineated. Eosinophils may promote or inhibit tumor growth, although the specific role in pancreatic cancer has yet to be determined. Eosinophil-supporting cytokine interleukin-5 and receptor are likely to have a role, but the significance in the pancreatic cancer microenvironment is unknown.

Fabrication of extended-dissolution divalproex tablets: a green solvent-free granulation technique.

Divalproex sodium (DVS) is a challenging drug owing to its hygroscopicity, bitter taste, and short half-life. This study aims to produce stable taste masked DVS once daily tablets using solvent free hot melt granulation (HMG) process. A lab scale high shear mixer granulator employing six meltable lipid binders (compritol888 ATO, beeswax, gelucire50/13, precirol ATO5, stearyl alcohol, and geleol) was used for the preparation of tablets.

Investigating Chaperonin-Containing TCP-1 subunit 2 as an essential component of the chaperonin complex for tumorigenesis.

Chaperonin-containing TCP-1 (CCT or TRiC) is a multi-subunit complex that folds many of the proteins essential for cancer development. CCT is expressed in diverse cancers and could be an ideal therapeutic target if not for the fact that the complex is encoded by eight distinct genes, complicating the development of inhibitors. Few definitive studies addressed the role of specific subunits in promoting the chaperonin's function in cancer.

Targeting chaperonin containing TCP1 (CCT) as a molecular therapeutic for small cell lung cancer.

Identifying new druggable targets is desired to meet the needs for effective cancer treatments. To this end, we previously reported the efficacy of a therapeutic peptide called CT20p that displays selective cytotoxicity through inhibition of a multi-subunit, protein-folding complex called Chaperonin-Containing TCP-1 (CCT). To investigate the role of CCT in cancer progression, we examined protein levels of CCT subunits in liver, prostate, and lung cancer using human tissue microarrays.

PSMA-Targeted Theranostic Nanocarrier for Prostate Cancer.

Herein, we report the use of a theranostic nanocarrier (Folate-HBPE(CT20p)) to deliver a therapeutic peptide to prostate cancer tumors that express PSMA (folate hydrolase 1). The therapeutic peptide (CT20p) targets and inhibits the chaperonin-containing TCP-1 (CCT) protein-folding complex, is selectively cytotoxic to cancer cells, and is non-toxic to normal tissue. With the delivery of CT20p to prostate cancer cells via PSMA, a dual level of cancer specificity is achieved: (1) selective targeting to PSMA-expressing prostate tumors, and (2) specific cytotoxicity to cancer cells with minimal toxicity to normal cells.

Chaperonin Containing TCP-1 Protein Level in Breast Cancer Cells Predicts Therapeutic Application of a Cytotoxic Peptide.

Purpose: Metastatic disease is a leading cause of death for patients with breast cancer, driving the need for new therapies. CT20p is a peptide previously discovered by our group that displays cancer-specific cytotoxicity. To design the optimal therapeutic use of the peptide, we identified the intracellular target of CT20p in breast cancer cells, correlating expression patterns of the target with susceptibility to CT20p.

Nlrc4/Ipaf/CLAN/CARD12: more than a flagellin sensor.

Nlrc4 is a member of the Nod-like receptors (NLRs), a family of cytosolic receptors involved in sensing bacterial molecules. NLRs are a group of proteins containing spans of leucine-rich repeats that senses bacterial factors within the eukaryotic cytosol. The recognition of bacterial factors provokes the formation of the inflammasome complex which includes specific NLRs.

Kaposi's sarcoma of the thyroid gland in an HIV-negative woman: a case report.

Background: Kaposi's sarcoma (KS) is a neoplastic disease that affects primarily the skin, but visceral involvement is not uncommon. Most of the cases are seen in AIDS patients and transplant recipients; however, rare HIV-negative cases have also been reported. Involvement of the thyroid is exceedingly rare, with only a fw cases reported, all of them associated with AIDS.

The role of donor bone marrow infusions in withdrawal of immunosuppression in adult liver allotransplantation.

We investigated the role of donor bone marrow cell (DBMC) infusions in immunosuppression withdrawal in adult liver transplantation. Patients enrolled were at least 3 years post-transplantation, with stable graft function. Forty-five (study group: G1) received DBMC, and 59 (control group: G2) did not.

Polyomavirus (BK virus) nephropathy in kidney transplant patients: a pathologic perspective.

Reactivation of polyoma virus (BK virus) is a significant cause of morbidity in kidney transplant patients. This seemingly insignificant viral infection that affects the majority of population at a young age, once reactivated by immunosuppression, is a major factor contributing to graft loss. Screening techniques have been developed for early prediction of BK virus reactivation.

Treatment of established recurrent hepatitis C in liver-transplant recipients with pegylated interferon-alfa-2b and ribavirin therapy.

Introduction: The management issues of transplant patients with hepatitis C virus (HCV) are complex, and interferon therapy is often ineffective. We present data from a retrospective review in liver-transplant recipients suffering from HCV recurrence that were treated with pegylated alpha-2b interferon and ribavirin.

Methods: A retrospective review of transplant recipients that received combination pegylated alpha-2b interferon (1.

Reliability of histopathologic assessment for the differentiation of recurrent hepatitis C from acute rejection after liver transplantation.

Histopathologic assessment is considered essential for the differentiation of recurrent hepatitis C (RHC) from acute cellular rejection (ACR) after liver transplantation (LT); however, there is limited information regarding its reliability. The aim of this study was to determine the interobserver and intraobserver agreement of the histopathologic diagnosis of RHC vs. ACR, and to determine the reliability of specific histopathologic features for the differentiation of RHC from ACR.

Prediction of sustained virological response in liver transplant recipients with recurrent hepatitis C virus following combination pegylated interferon alfa-2b and ribavirin therapy using tissue hepatitis C virus reverse transcriptase polymerase chain reaction testing.

The optimal duration of therapy for pegylated interferon combined with ribavirin in recurrent Hepatitis C virus (HCV) following liver transplantation is not known. We wanted to determine if testing for HCV in liver tissue by reverse transcriptase polymerase chain reaction (RT-PCR) was superior in predicting sustained virological response (SVR) in comparison to standard HCV ribonucleic acid (RNA) detection in the serum. All recipients received combination pegylated alpha-2b interferon (1.

Histologic features of mycophenolate mofetil-related colitis: a graft-versus-host disease-like pattern.

Mycophenolate mofetil (MMF) is widely used for maintenance immunosuppression in solid organ transplantation. Gastrointestinal toxicity, usually manifested as diarrhea, is the most common side effect of MMF. We evaluated colonic biopsies from 20 renal transplant patients with MMF-related diarrhea.

Bax deficiency partially corrects interleukin-7 receptor alpha deficiency.

The requirement for cytokines in hematopoiesis is partly attributable to the protection of cells from apoptosis. Since IL-7 is required for normal T cell development, we evaluated the role of Bax in vivo by generating mice deficient in both Bax and the IL-7 receptor alpha chain (IL-7R). Starting at birth, we observed complete recovery of all stages of alphabeta thymocyte development up to 4 weeks of age.
