Preoperative diagnosis of primary ovarian lymphoma: a case report and a decade of insights.

Through a comprehensive retrospective analysis of a 52-year-old woman with primary ovarian lymphoma (POL) and a review of similar cases over the past decade in the PubMed database, we gained several key insights into improving the understanding of POL among clinicians and radiologists for accurate diagnosis. POL is more prevalent among women in their 40s and usually presents with clinical manifestations of a solid mass (typically over 10 cm) and abdominal pain with B symptoms. Four imaging features show promise as indicators of potential diagnostic value in POL: the ovarian retention sign, touching ovaries, vascular floatation, and the sandwich sign.

Imaging manifestations of cervical aggressive fibromatosis: a case report and literature review.

Cervical aggressive fibromatosis is a rare intermediate tumor characterized by invasive growth. Aggressive fibromatosis (AF), also referred to as desmoid-type fibrosarcoma or grade I fibrosarcoma, is a clonal proliferative lesion of fibroblasts located in deep soft tissues. While many cases have been reported, there are relatively few involving aggressive fibromatosis in the anterior inferior margin muscle space of the neck trapezius muscle.

Discovery, development and optimisation of a novel frog antimicrobial peptide with combined mode of action against drug-resistant bacteria.

Antimicrobial peptides (AMP) have emerged as promising candidates for addressing the clinical challenges posed by the rapid evolution of antibiotic-resistant microorganisms. Brevinins, a representative frog-derived AMP family, exhibited broad-spectrum antimicrobial activities, attacking great attentions in previous studies. However, their strong haemolytic activity and cytotoxicity, greatly limit their further development.

Advances of Iron and Ferroptosis in Diabetic Kidney Disease.

Diabetes mellitus presents a significant threat to human health because it disrupts energy metabolism and gives rise to various complications, including diabetic kidney disease (DKD). Metabolic adaptations occurring in the kidney in response to diabetes contribute to the pathogenesis of DKD. Iron metabolism and ferroptosis, a recently defined form of cell death resulting from iron-dependent excessive accumulation of lipid peroxides, have emerged as crucial players in the progression of DKD.

Multi-faceted effects of NaCl on salt-tolerant microalgae Golenkinia sp. SDEC-16.

The salt-tolerant microalgae are extremely few and salt-tolerance mechanism is unclear, requiring urgent exploration of salt-tolerance mechanism of known microalgae. This study was first to reveal the salt-tolerance mechanism of Golenkinia sp. SDEC-16 by investigating the growth and metabolism under different salinities and high salinity long-term cultivation.

Cranial Rosai-Dorfman disease: a case report and literature review.

Rosai-Dorfman Disease (RDD) is a rare, benign, idiopathic histiocytic proliferative disorder, with its occurrence in the cranial bones being particularly uncommon and prone to misdiagnosis in preoperative radiological examinations. This article reports a case of RDD in the left temporal bone. The radiological presentation of intraosseous RDD includes osteolytic bone destruction, infrequent periosteal reaction, clearly defined tumor margins, and marked uniform enhancement on contrast-enhanced scans.

The imaging dynamic changes in the malignant transformation of an epidermoid cyst: a case report and literature review.

Malignant transformation of epidermoid cysts is a rare complication. Most of the previously reported cases have involved postoperative malignant transformations. We present a case of malignant transformation of a nonpostoperative epidermoid tumor into squamous cell carcinoma (SCC) that occurred in a 61-year-old Chinese woman.

Frontotemporal giant extradural dermoid cyst: illustrative case.

Background: Dermoid cyst is a rare benign tumor exhibiting a typical radiological pattern and most commonly located along the midline. Laboratory examination was always normal. However, the features of some rare cases are atypical that can be easily misdiagnosed as other tumors.

Transformation of lymphoid interstitial pneumonia (LIP) into malignant lymphoma in patients with Sjogren's syndrome: a case report and literature review.

Background: Lymphoid interstitial pneumonia (LIP) is a very rare disease and its malignant transformation is even more rare. LIP is easily misdiagnosed by clinicians and radiologists.

Case Presentation: The medical record of a 64-year-old female with Sjogren's syndrome was reviewed.

The Risk Assessment and Clinical Research of Bile Duct Injury After Transcatheter Arterial Chemoembolization for Hepatocellular Carcinoma.

Purpose: To retrospectively evaluate the risk factors and the clinical outcomes of bile duct injury after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) and to evaluate factors that aid clinical detection and subsequent treatment of the injured bile duct.

Materials And Methods: All patients undergoing TACE for HCC were retrospectively reviewed for identification of bile duct injury. The clinical spectrum of all the patients analyzed including patients' demographics, laboratory data, radiologic imaging and mode of treatment.

A simple matrine derivative for the facile syntheses of mesoporous zeolites ITQ-37 and ITQ-43.

ITQ-37 and ITQ-43 possessing mesoporous structures have aroused great interest because of their promising applications involving large molecules. However, it is challenging to synthesize these zeolites. Herein, MAS-ITQ-37 and MAS-ITQ-43 with enhanced Si/Ge ratios of 1.

Characterization of single lesion nonfunctioning pancreatic neuroendocrine carcinoma via computed tomography.

Nonfunctioning pancreatic neuroendocrine carcinoma (NPNEC) is a poorly differentiated neuroendocrine carcinoma and a rare type of pancreatic cancer. Computed tomography (CT)-based imaging is currently the most effective method for diagnosing and classifying NPNEC. The present study investigated the clinical features and CT manifestations of this disease.

Clinicopathological characteristics of mediastinal follicular dendritic cell sarcoma: report of three cases.

Background: Follicular dendritic cell sarcoma (FDCS) is a rare malignant neoplasm of follicular dendritic cells that form a tight meshwork within lymphoid follicles. It occurs most commonly in the lymph nodes and occasionally at extranodal sites, but rarely in the mediastinum. It is an under-recognized clinical entity without clear diagnosis.

[Optimization of scan protocol in pulmonary angiography of second generation dual source computed tomography].

Objective: To explore the scan protocol of second generation dual source computed tomography (CT) for CT pulmonary angiogram (CTPA) in patients with suspected pulmonary embolism and determine the proper volume of contrast medium.

Methods: A total of 120 patients undergoing CTPA were recruited. All examinations were performed on a second generation dual source CT.

[Localization of upper airway stricture by CT scan in patients with obstructive sleep apnea syndrome during drug-induced sleeping].

Objective: To evaluate the feasibility of multi-slice spiral CT scan to localize upper airway stricture in patients with obstructive sleep apnea syndrome (OSAS) during drug-induced sleeping.

Methods: One hundred and fourteen patients diagnosed as OSAS by polysomnography were included in the study. Multi-slice spiral CT scan covering upper airway was performed at the end of inspiration and clear upper airway images were obtained in waking.

Perivascular epithelioid cell tumor of the liver: a report of two cases and review of the literature.

Perivascular epithelioid cell tumor (PEComa) is a rare tumor which arises from mesenchymal tissues. It is predominant in the uterus, but very rare in the liver. To the best of our knowledge, less than 5 cases of PEComa of the liver have been reported.

[A report of 12 cases of primary pulmonary cryptococcosis].

Objective: The purpose of this study was to analyze the chest CT findings of immunocompetent patients with primary pulmonary cryptococcosis and to evaluate the utility of CT-guided percutaneous biopsy in the diagnosis.

Methods: Chest CT scans of 12 immunocompetent patients with biopsy-proven primary pulmonary cryptococcosis were analyzed for the number of lesions, morphologic characteristics, distribution of parenchymal abnormalities, and the presence of lymphadenopathy and pleural effusion. Lung specimens were obtained by CT guided percutaneous biopsy (n = 9) and/or surgical resection (n = 7).
