Discovery of a novel rhein-SAHA hybrid as a multi-targeted anti-glioblastoma drug
Summary Glioblastoma multiforme (GBM) is the most common malignant tumor of the central nervous system (CNS). Effective treatments remain limited. Therefore, novel chemotherapy drugs with high efficiency and few adverse effects are urgently needed. Histone deacetylase (HDAC) and serum and glucocorticoid-regulated protein kinase 1 (SGK1) are targets for the prevention and treatment of GBM. Rhein has antitumor and SGK1 suppression effects, although its biological activity is limited...

Identification of HGF as a novel target of miR-15a/16/195 in gastric cancer
Summary Background Gastric malignancy is the third most frequently encountered cancer globally and have been documented to confer extremely poor prognosis, given their limited treatment options. The up-regulation of hepatocyte growth factor (HGF) has been found in various tumor tissues, including GC tissue, and has been linked with tumor development. Nevertheless, the pathways leading to HGF upregulation have yet to be fully explored. Methods Immunohistochemistry (IHC) assay was...

Role of imaging in the evaluation of vascular complications after liver transplantation
Abstract Clinical manifestations of liver transplantation complications can be subtle and non-specific. Medical imaging, mainly Doppler ultrasound, plays an important role to detect and grade these. Colour Doppler ultrasound exams are routinely performed at 24–48 h, on the 7th day, the first and third month after transplantation. MDCT and MR images are acquired based on the Doppler ultrasound (DUS) findings, even in the absence of abnormal liver function. As vascular complications...

Meckel syndrome: Clinical and mutation profile in six fetuses
Abstract Meckel syndrome (MKS) is a perinatally lethal, genetically heterogeneous, autosomal recessive condition caused by defective primary cilium formation leading to polydactyly, multiple cysts in kidneys and malformations of nervous system. We performed exome sequencing in six fetuses from six unrelated families with MKS. We identified seven novel variants in B9D2, TNXDC15, CC2D2A, CEP290 and TMEM67. We describe the second family with MKS due to a homozygous variant in B9D2 and fifth...

Immunohistochemistry for ATRX Can Miss ATRX Mutations: Lessons From Neuroblastoma
Neuroblastoma is the most common extracranial solid tumor of childhood with a median age of presentation of 17 months. A common theme in high-risk neuroblastoma is maintenance of telomeres, one mechanism for which involves alternate lengthening of telomeres (ALT) associated with ATRX gene mutations. Mutations are believed to result in loss of ATRX protein, and therefore immunohistochemistry is used to detect mutations. We screened 133 cases of neuroblastoma by ATRX immunohistochemistry, and found...

However, the reasons for this difference are poorly understood.

Thus, we retrospectively analyzed the outcomes of YKS treatment on patients with RBD using clinical records.Methods:Treatment outcomes were evaluated using the Clinical Global Impression of Illness Severity (CGI-S) and Improvement (CGI-I)...

Ticagrelor-Associated Shift From Obstructive to Central Sleep Apnea: A Case Report
Ticagrelor, a P2Y12 receptor antagonist, is used in combination with aspirin in patients with coronary artery disease. Recent reports suggest that ticagrelor might induce central sleep apnea (CSA) by increasing chemosensitivity to hypercapnia. We herein describe the case of a patient with positive airway pressure (PAP)-treated obstructive sleep apnea (OSA), in whom PAP-telemonitoring revealed the emergence of CSA and Cheyne-Stokes respiration (CSR) after initiation of ticagrelor for an acute coronary...

Images: Periodic Limb Movements During Sleep Noted on Ventral Thigh Surface Electromyography in an Above-the-Knee Amputated Stump
Ventral thigh surface electromyography may be used to assess for periodic limb movements during sleep (PLMS) in a limb with an above-the-knee amputation. Presence of PLMS in the proximal portion of an amputated lower extremity supports theories of spinal and supraspinal mechanisms in PLMS generation, and demonstrates that intact distal motor efferent pathways and distal sensory afferent pathways are not absolutely necessary for the generation of periodic limb movements.Citation:Chada A, Hoque R....

Development of Novel Topical Cosmeceutical Formulations from Nigella sativa L. with Antimicrobial Activity against Acne-Causing Microorganisms
Acne vulgaris occurs due to the inflammation of sebaceous follicles in the skin. It is triggered by the activity of some bacterial species like Propionibacterium acnes, Staphylococcus aureus, and Staphylococcus epidermidis. Acquisition of antibiotic resistance by these microorganisms and adverse effects associated with the current treatment regimens necessitate the introduction of novel therapeutic agents for acne vulgaris. Thus, this study was undertaken to develop novel gel formulations from seeds...

Rosai-Dorfman Disease of the Digestive System—Beware Vasculopathy: A Clinicopathologic Analysis
Rosai-Dorfman disease (RDD) is a rare non-Langerhans cell histiocytic proliferation that occurs in nodal and extranodal sites. Rare examples of the disease involving the digestive system have been described. To characterize the digestive tract manifestations of this disease, 12 specimens from 11 patients with extranodal RDD affecting the digestive organs were analyzed. Hematoxylin and eosin sections and available immunohistochemical stains were reviewed, and the clinical information was obtained...

A black esophagus as a result of treatment of inferior vena cava occlusion by a massive pelvic schwannoma
AbstractThis case presentation involves a 57-year-old-male who suffered multiple adverse sequels from the delayed diagnosis of a large presacral mass. He initially presented with lower extremity deep vein thrombosis (DVT). Several months later, he had developed a pulmonary embolus. Imaging demonstrated a 13 × 14 cm presacral pelvic mass that occluded the right-sided venous return from the leg and caused the DVT and pulmonary embolism. An inferior vena cava filter was placed and eventually clotted....

Appendiceal mucocele secondary to torsion in an asymptomatic patient
AbstractTorsion of the appendix associated with an appendiceal mucocele is extremely rare with just a few published cases. To our knowledge, we report the first case of appendiceal mucocele secondary to torsion in an asymptomatic patient. In this case, numerous adhesions were found attaching the tip of the appendix mucocele to the peritoneum contributing to torsion as well as a lack of evidence for appendiceal neoplasm. Complications of appendiceal mucocele include obstruction, intussusception and...

Ureteric reimplantation via vaginal route: a new surgical technique
AbstractVesicovaginal fistulae (VVF) and ureteric reimplantation are two rare complications of obstetric surgery. VVF can be repaired via a vaginal approach utilizing Martius fat pad interposition to minimize urethral complications and improve surgical outcomes, while ureteric reimplantation into the bladder classically necessitates an abdominal or laparoscopic approach. We present a new technique of ureteric reimplantation via vaginal approach with concomitant repair of a 5-cm VVF in a 25-year-old...

Transferable Mechanisms of Quinolone Resistance from 1998 Onward [Reviews]
While the description of resistance to quinolones is almost as old as these antimicrobial agents themselves, transferable mechanisms of quinolone resistance (TMQR) remained absent from the scenario for more than 36 years, appearing first as sporadic events and afterward as epidemics. In 1998, the first TMQR was soundly described, that is, QnrA. The presence of QnrA was almost anecdotal for years, but in the middle of the first decade of the 21st century, there was an explosion of TMQR descriptions,...

Migrating to the Middle East in Search of Safety

Verbal abuse against home care aides: another shot across the bow in violence against health care and other workers

Role of asbestos clearance in explaining long-term risk of pleural and peritoneal cancer: a pooled analysis of cohort studies
ObjectivesModels based on the multistage theory of cancer predict that rates of malignant mesothelioma continuously increase with time since first exposure (TSFE) to asbestos, even after the end of external exposure. However, recent epidemiological studies suggest that mesothelioma rates level off many years after first exposure to asbestos. A gradual clearance of asbestos from the lungs has been suggested as a possible explanation for this phenomenon. We analysed long-term trends of pleural and...
