Müllerian Cysts of the Posterior Mediastinum: A Case Report and Review of the Literature.

Cysts can be segregated according to their embryonic backgrounds. The cysts that were found in the mediastinum are usually divided into bronchogenic cysts, enteric cysts, esophageal cysts, and nonspecific cysts. We add to the relatively small body of literature that exists on this topic by reporting a case of a Müllerian cyst occurring in the posterior mediastinum of a 60-year-old female, showing diffuse nuclear positivity for estrogen receptor (ER) and PAX-8.

Neuroinvasion of SARS-CoV-2 in human and mouse brain.

Although COVID-19 is considered to be primarily a respiratory disease, SARS-CoV-2 affects multiple organ systems including the central nervous system (CNS). Yet, there is no consensus on the consequences of CNS infections. Here, we used three independent approaches to probe the capacity of SARS-CoV-2 to infect the brain.

Evaluating survival in subjects with astrocytic brain tumors by dynamic susceptibility-weighted perfusion MR imaging.

Purpose: Studies have evaluated the application of perfusion MR for predicting survival in patients with astrocytic brain tumors, but few of them statistically adjust their results to reflect the impact of the variability of treatment administered in the patients. Our aim was to analyze the association between the perfusion values and overall survival time, with adjustment for various clinical factors, including initial treatments and follow-up treatments.

Materials And Methods: This study consisted of 51 patients with astrocytic brain tumors who underwent perfusion-weighted MRI with MultiHance® at a dose of 0.

A solitary extraventricular subependymal giant cell astrocytoma in the absence of tuberous sclerosis.

Subependymal giant cell astrocytomas (SEGAs) are the most common intracranial tumors in Tuberous Sclerosis Complex (TSC). Very few cases of solitary SEGA without a diagnosis of TSC have been described. Most of these previously reported solitary SEGAs were located near the caudothalamic groove or in close proximity to the lateral ventricles.

Neuroinvasion of SARS-CoV-2 in human and mouse brain.

Although COVID-19 is considered to be primarily a respiratory disease, SARS-CoV-2 affects multiple organ systems including the central nervous system (CNS). Yet, there is no consensus whether the virus can infect the brain, or what the consequences of CNS infection are. Here, we used three independent approaches to probe the capacity of SARS-CoV-2 to infect the brain.

Evaluation of wound healing effects of Syzygium cumini and laser treatment in diabetic rats.

This study was aimed to investigate the antioxidant effects of Syzygium cumini (S. cumini) seeds extract along with wound healing score in correlation to glutathione and blood glucose levels in diabetic rats. Sprague-Dawley rats were divided into 8 groups (n=6) and diabetes was induced by a single intraperitoneal injection of streptozotocin (40 mg kg-1 body weight).

Post-operative perfusion and diffusion MR imaging and tumor progression in high-grade gliomas.

Purpose: Perfusion and diffusion magnetic resonance imaging (MRI) provide important biomarkers for brain tumor analysis. Our aim was to investigate if regions of increased perfusion or tumor with restricted diffusion on the immediate post-operative MRI examination would be predictive of time to tumor progression in patients with high-grade gliomas.

Materials And Methods: Twenty-three patients with high-grade gliomas were retrospectively analyzed.

Antimicrobial activity of extracts against multi-drug resistant from patients of urinary tract infection.

Background And Objective: is the most common etiological agent of UTI and accounts for more then 100, 0000 hospitalization annually. The objective of this study was to investigate the antimicrobial activity of aqueous and ethanolic extracts of against from urinary tract infection patients.

Methods: Urine samples of forty four suspected patients from Tertiary Care Hospital Faisalabad were used in this study.

: A Rare Intracerebral Fungal Abscess-Case Series and Review of Literature.

 Intracerebral may carry up to a 70% mortality rate despite advances in surgical resection capabilities and the use of both systemic and intrathecal antifungal treatments.  The authors examined a retrospective case series of two patients with intracerebral infection from the rare, neurotropic fungus and conducted a literature review to evaluate optimal therapies.  At our institution, the patients' cases presented with raised intracranial features of headache, visual field cut, and/or memory loss, with a correspondingly wide variety of radiological differential diagnoses.

Biaxial mechanical properties of the human thoracic and abdominal aorta, common carotid, subclavian, renal and common iliac arteries.

The biomechanics of large- and medium-sized arteries influence the pathophysiology of arterial disease and the response to therapeutic interventions. However, a comprehensive comparative analysis of human arterial biaxial mechanical properties has not yet been reported. Planar biaxial extension was used to establish the passive mechanical properties of human thoracic (TA, [Formula: see text]) and abdominal (AA, [Formula: see text]) aorta, common carotid (CCA, [Formula: see text]), subclavian (SA, [Formula: see text]), renal (RA, [Formula: see text]) and common iliac (CIA, [Formula: see text]) arteries from 11 deceased subjects ([Formula: see text] years old).

Passive biaxial mechanical properties and in vivo axial pre-stretch of the diseased human femoropopliteal and tibial arteries.

Surgical and interventional therapies for atherosclerotic lesions of the infrainguinal arteries are notorious for high rates of failure. Frequently, this leads to expensive reinterventions, return of disabling symptoms or limb loss. Interaction between the artery and repair material likely plays an important role in reconstruction failure, but data describing the mechanical properties and functional characteristics of human femoropopliteal and tibial arteries are currently not available.

Multifocal histologically malignant Epstein-Barr virus-associated smooth muscle tumor in a pediatric transplant patient with an indolent course.

Epstein-Barr virus-associated smooth muscle tumors (EBV-SMTs) are rare lesions that occur in immunocompromised patients. Dural involvement appears to be less common in organ transplant recipients than in HIV patients. Due to the paucity of reported cases following organ transplantation, the natural history of these lesions is unclear.

Effects of carotid artery stenting on arterial geometry.

Background: The role of carotid artery stenting (CAS) for the treatment of carotid artery disease continues to evolve, despite higher stroke and restenosis risks for CAS compared with conventional open endarterectomy. Understanding the effects of CAS on arterial geometry, which strongly influence hemodynamics and wall mechanics, can assist in better stratifying the inherent risk of CAS to individual patients.

Study Design: Fifteen consecutive patients undergoing CAS had pre- and post-stenting CT angiograms.

Metastases from nested variant urothelial carcinoma of the urinary bladder in pancreatic allograft mimicking graft rejection.

Unlabelled: While not an uncommon tumor, urothelial carcinoma of the urinary bladder is rare in bladders draining pancreatic allografts. A case of urothelial carcinoma directly involving a pancreatic allograft with metastasis that occurred in a 49-year-old pancreas and kidney transplant recipient is described. Her initial clinical presentation and findings of CT scan of the abdomen suggested pancreatitis with features worrisome for rejection.

Comparative analysis of the biaxial mechanical behavior of carotid wall tissue and biological and synthetic materials used for carotid patch angioplasty.

Patch angioplasty is the most common technique used for the performance of carotid endarterectomy. A large number of patching materials are available for use while new materials are being continuously developed. Surprisingly little is known about the mechanical properties of these materials and how these properties compare with those of the carotid artery wall.

Background. Teratoma with malignant transformation (TMT) is rare and most commonly encountered in adult patient with germ cell tumor (GCT). Method.

Influence of sibutramine, orlistat and Ispaghula in reducing body weight and total body fat content in obese individuals.

Background: The correlations between combined body fat parameters and risk factors of obesity explained a portion of the variation in the weight, BMI and waist circumference, the average number of categorical metabolic risk factors increases progressively with increasing total body fat content. There is currently no data available in which influence of drugs can be assessed on total body fat content. This was a non-randomized, prospective, open-label, parallel group study was conducted to compare the effectiveness of sibutramine, orlistat and ispahgula in reducing body weight and percentage of total body fat content in obese individuals.

Primary Ewing sarcoma of the brain: a case report and literature review.

Ewing sarcoma, along with peripheral primitive neuroectodermal tumor, belongs to a tumor family that shares clinicopathologic and molecular genetic features, including the characteristic chromosomal translocation that results in the fusion of the EWS gene on 22q12 to either the FLI1 gene on 11q24 or other Ets family transcription factor gene, such as the ERG gene on 21q22. In contrast, such translocations are not found in central primitive neuroectodermal tumors (cPNETs), such as medulloblastoma and supratentorial PNET. Ewing sarcoma has only rarely been noted to primarily involve the central nervous system-extraosseous Ewing sarcoma (CNS-EES).
