Retroperitoneal ectopic pregnancy: A case report.

Retroperitoneal ectopic pregnancy is a rare form of ectopic pregnancy. In these cases, the gestational sac tends to attach near large retroperitoneal vessels, so when the sac ruptures, it can lead to severe bleeding, posing a life-threatening risk to the patient. Therefore, early diagnosis of ectopic pregnancy at this location is crucial.

Free vascularized fascia lata flap combined with skin grafting for reconstruction of complex defect of the foot dorsum - A case report.

Introduction: The dorsum of the foot has distinct characteristics, including thin skin and minimal subcutaneous tissue. Injuries in this area can expose deeper structures, complicating recovery and increasing the risk of infection and tissue necrosis. This article discusses using a free vascularized fascia lata (FL) flap combined with a skin graft to achieve effective skin coverage in a single stage.

CeO -anchored β-Ni(OH) nanosheets onto nickel foam for efficient energy-saving hydrogen production an electrocatalytic glucose oxidation reaction.

Electrolytic glucose oxidation has garnered great interest in energy-saving hydrogen generation. However, high charge-transfer resistance and inefficient active centers have been recognized as the primary issues for poor electrochemical performance. In this study, for the first time, we offer a novel defect-rich CeO /β-Ni(OH) composite nanosheet-decorated Ni foam electrocatalyst (denoted as Ce@NF-GA), synthesized a unique hydrothermal approach under the co-participation of glycerol and acetic acid.

Apparent diffusion coefficient histogram in the differentiation of benign and malignant testicular tumors.

This retrospective study assessed the value of histogram parameters of the apparent diffusion coefficient (ADC) map (HA) in differentiating between benign and malignant testicular tumors. We compared the diagnostic performance of two different volume-of-interest (VOI) placement methods: VOI 1, the entire tumor; VOI 2, the tumor excluding its cystic, calcified, hemorrhagic, and necrotic portions. We retrospectively evaluated 45 patients with testicular tumors examined with scrotal contrast-enhanced magnetic resonance imaging.

Differentiation of glioblastoma and primary central nervous system lymphomas using multiparametric diffusion and perfusion magnetic resonance imaging.

The present study aimed to determine whether combining diffusion-weighted (DWI) and dynamic susceptibility contrast-enhanced perfusion-weighted (DSC-PWI) magnetic resonance imaging (MRI) could differentiate between primary central nervous system lymphoma (PCNSL) and glioblastoma (GBM). The present retrospective study evaluated 45 patients with histologically confirmed brain tumors, of which 18 had PCNSLs and 27 had GBMs. All patients underwent conventional, DWI, and DSC-PWI MRIs before the surgical removal of the lesion or stereotactic biopsy.

A glucose-assisted redox hydrothermal route to prepare a Mn-doped CeO catalyst for the total catalytic oxidation of VOCs.

In this study, a novel glucose-assisted redox hydrothermal method has been presented to prepare an Mn-doped CeO catalyst (denoted as Mn-CeO-R) for the first time. The obtained catalyst contains uniform nanoparticles with a small crystallite size, a large mesopore volume, and rich active surface oxygen species. Such features collectively contribute to improving the catalytic activity for the total catalytic oxidation of methanol (CHOH) and formaldehyde (HCHO).

Juvenile psammomatoid ossifying fibroma in paranasal sinuses: A case report and literature review.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, benign type of ossifying fibroma. JPOFs predominantly present as rapidly growing masses with a high recurrence rate. We report a 40-year-old male patient who suffered from a large tumor with multiple invasions into the paranasal sinuses.

Low apparent diffusion coefficient in an extracranial brain tumor: a case report.

Background: Medulloblastoma is well known as the most common malignant brain tumor identified in children, frequently found at an intra-axial location in the posterior cranial fossa. Extra-axial medulloblastoma is uncommon and often misdiagnosed. We believe that a thorough understanding of atypical medulloblastoma cases is important in daily practice.

Diagnosis of symmetric bilateral lateral ventricular subependymomas: A case report.

Subependymomas are rare benign tumors that are hypovascular and noninvasive. Subependymomas tend to present as solitary lesions in the fourth ventricle or the frontal horn of the lateral ventricle. When multiple lesions are present, determining the correct diagnosis between subependymoma and other intraventricular neoplasms can be challenging.

The efficacy of quantitative magnetic resonance imaging in the diagnosis of unstable L4/L5 degenerative spondylolisthesis.

Lumbar degenerative spondylolisthesis (LDS) is a common degenerative disease that particularly affects the elderly. LDS can occur in any segment of the spine but is most commonly found in the L4/L5 segment. In the present study, a quantitative study of lumbar MRI measurements was conducted to identify predisposing factors indicative of spinal instability in patients with L4/L5 LDS.

Phlebosclerotic colitis with long-term herbal medicine use.

Phlebosclerotic colitis (PC), also known as idiopathic mesenteric phlebosclerosis, is a rare disease resulting in ischemic colon due to venous sclerosis and calcifications that can be identified by characteristic imaging features on computed tomography and colonoscopy. Clinical examination reveals nonspecific symptoms with slow progression in the majority of cases. Patients with PC often require late-stage hospitalization and colectomy.

Gastric rupture following multiple blunt trauma.

Gastric injury due to trauma is a rare complication that occurs in approximately 0.04%-1.2% of all instances of abdominal trauma.

Primary intraventricular gliosarcoma on MRI: A challenging diagnosis.

Gliosarcoma (GS) is an uncommon central nervous system tumor with several characteristics of a malignant neoplasm and poor prognosis. The majority of GS reports describe a predilection for the cerebral hemispheres, and cases of intraventricular GS are extremely rare, with only a few reported. In addition, intraventricular GS has not been associated with any unique radiographic or clinical features, which can result in misdiagnosis as other intraventricular tumor types.

Green synthesis of microalgae-based carbon dots for decoration of TiO nanoparticles in enhancement of organic dye photodegradation.

TiO is a well-known semiconductor used widely in the photocatalyst field, but its photocatalytic applications are hampered by a fast electron-hole recombination rate and low visible light absorption due to a wide-band-gap energy. Herein, we present a simple, low cost, and green approach to obtain carbon dots from microalgae, namely microalgae-based carbon dots (MCDs), using an unprecedented microwave-assisted treatment. The MCDs were successfully decorated on the surface of TiO nanoparticles.

Novel Architecture Titanium Carbide (TiCT) MXene Cocatalysts toward Photocatalytic Hydrogen Production: A Mini-Review.

Low dimensional transition metal carbide and nitride (MXenes) have been emerging as frontier materials for energy storage and conversion. TiCT was the first MXenes that discovered and soon become the most widely investigated among the MXenes family. Interestingly, TiCT exhibits ultrahigh catalytic activity towards the hydrogen evolution reaction.
