Does portal vein anatomy influence intrahepatic distribution of metastases from colorectal cancer?

Background: Other than location of the primary colorectal cancer (CRC), a few factors are known to influence the intrahepatic distribution of colorectal cancer liver metastases (CRLM). We aimed to assess whether the anatomy of the portal vein (PV) could influence the intrahepatic distribution of CRLM.

Patients And Methods: Patients with CRLM diagnosed between January 2018 and December 2022 at two tertiary centers were included and imaging was reviewed by two radiologists independently.

Imaging findings of thoracic manifestations of Crohn's disease and ulcerative colitis.

Thoracic manifestations of inflammatory bowel disease (IBD) are rare, occurring in less than 1% of patients. Unlike most other extra-intestinal manifestations, they predominate in patients with ulcerative colitis rather than in Crohn's disease. In most patients, thoracic involvement follows the onset of IBD by several years.

Patients who underwent preoperative TAE of hypervascular musculoskeletal tumors between January 2018 and December 2021 were retrospectively included. The patients' characteristics, TAE procedure details, degree of post-TAE devascularization, surgical outcomes in terms of red blood cell transfusion and functional results were collected.

Biofouling of reverse osmosis membranes: assessment by surface-enhanced Raman spectroscopy and microscopic imaging.

The decline in the performance of spiral-wound reverse osmosis (SWRO) membranes is frequently due to biofouling. This study focus on qualitative and quantitative diagnosis of SWRO membrane biofouling. Bacterial counts on the different surfaces of the fouled membranes were carried out.

Focal splenic lesions: Imaging spectrum of diseases on CT, MRI and PET/CT.

The spleen can be affected by a variety of diseases. Some of them are readily identified as variations of normal or benign diseases on imaging. However, for a substantial number of focal splenic abnormalities, the diagnosis can be difficult so that histopathologic analysis may be required for a definite diagnosis.

CT features of lung metastases from pancreatic adenocarcinoma: Correlation with histopathologic findings.

Purpose: The purpose of this study was to evaluate the prevalence of an atypical, alveolar presentation of pulmonary metastases from pancreatic adenocarcinoma (PDAC) on computed tomography (CT) and to correlate CT features with those obtained at histopathologic analysis.

Material And Methods: A total of 76 patients with lung metastases from PDAC over a 10-year period (2009-2019) in a French university hospital were retrospectively included. There were 34 men and 42 women with a mean age of 67.

Synthesis, biological activity and POM/DFT/docking analyses of annulated pyrano[2,3-d]pyrimidine derivatives: Identification of antibacterial and antitumor pharmacophore sites.

New annulated pyrano[2,3-d]pyrimidine derivatives were synthesized with hydroxyl, methoxy, bromine, nitrile and nitro substituents on its skeleton. The correlated electronic effect of substituents on the magnitude of antibacterial activity was noted. The electron donating substituents (namely; 4-OH, 4-OCH, 4-Br) and electron withdrawing substituents (4-NO) on phenyl ring in the pyrano[2,3-d]pyrimidine skeleton exerted different influence on its antimicrobial activity against some Gram-positive and Gram-negative bacteria such as Pseudomonas aureus, E.

Methods: The analysis of green seeds extracts was carried out by RP-HPLC-PDA. These extracts were screened for antioxidant activities by ABTS and phenanthroline assays.

Association of TERT, OGG1, and CHRNA5 Polymorphisms and the Predisposition to Lung Cancer in Eastern Algeria.

Lung cancer remains the most common cancer in the world. The genetic polymorphisms (rs2853669 in TERT, rs1052133 in OGG1, and rs16969968 in CHRNA5 genes) were shown to be strongly associated with the risk of lung cancer. Our study's aim is to elucidate whether these polymorphisms predispose Eastern Algerian population to non-small-cell lung cancer (NSCLC).

Three-Dimensional Analysis of the Interactions between hLDH5 and Its Inhibitors.

Inhibitors of human lactate dehydrogenase (LDH5)-the enzyme responsible for the conversion of pyruvate to lactate coupled with oxidation of NADH to NAD⁺-are promising therapeutic agents against cancer because this enzyme is generally found to be overexpressed in most invasive cancer cells and is linked to their vitality especially under hypoxic conditions. Consequently, significant efforts have been made for the identification of small-molecule LDH5 inhibitors displaying high inhibitory potencies. X-ray structure of LDH5 complexes as well as molecular modeling studies contribute to identify and explain the main binding modes of LDH5 inhibitors reported in literature.

Effectiveness of heart rate control on hemodynamics in critically ill patients with atrial tachyarrhythmias managed by amiodarone.

Atrial tachyarrhythmias (AT) are common in intensive care unit (ICU) patients and might contribute to hemodynamic instability if heart rate (HR) is persistently too rapid. We aimed to assess if HR control below 115 or 130bpm with amiodarone improves hemodynamics in ICU patients with AT. This observational study included 73 ICU patients with disabling AT receiving amiodarone for HR control.

Modeling of Amiodarone Effect on Heart Rate Control in Critically Ill Patients with Atrial Tachyarrhythmias.

Aims: Amiodarone is the gold-standard medication to control heart rate in critically ill patients with atrial tachyarrhythmias (ATs); however, effective doses and covariates influencing its efficacy remain unknown. We therefore performed pharmacodynamic modeling of heart rate reduction induced by amiodarone in these patients.

Methods And Results: This observational study included 80 consecutive severely ill patients receiving amiodarone to treat ATs.

The long-term impact of early cardiovascular therapy intensification for postoperative troponin elevation after major vascular surgery.

Background: Acute cardiac events are a frequent cause of morbidity after vascular surgery. The impact of early evidence-based treatment for patients with an acute cardiac event after vascular surgery on long-term postoperative outcomes has not been extensively studied. We hypothesized that providing appropriate evidence-based treatment to patients with elevated postoperative cardiac troponin levels may limit long-term mortality.

Efficacy of low-dose oral sulodexide in the management of diabetic nephropathy.

Background: Diabetic nephropathy (DN) is the single greatest cause of end-stage renal disease (ESRD). Without specific interventions, microalbuminuria (incipient nephropathy) gradually progresses to macroalbuminuria (overt nephropathy) within 10-15 years in about 80% of type 1 and 30% of type 2 diabetic patients, and to ESRD within further 20 years in about 75% and 20%, respectively. A primary alteration in DN consists of decreased concentration of glycosaminoglycans (GAGs) in the glomerular extracellular matrix.

Chronic generalized eczema caused by multiple dye sensitization.

Textile dye sensitization is rare; its low incidence (1.4% to 5.8%) is most likely because dye contact allergy is not suspected and therefore not tested.
