Published: September 2012

The generation of the first persistent radical cation of naphthalenediimide with Cu(2+)/Fe(3+) under ambient conditions is reported. An alternate anionic trigger generates a persistent radical anion within the same motif. Steric protection and H-bonding enhances the half-life of radical cation by 290-fold. The radical anion and cation have orthogonal spin density, panchromatic and NIR optical bands, which can be applied as attractive multichannel probes.

Unlabelled: is one of the most virulent bacterial pathogens known and causes the disease tularemia, which can be fatal if untreated. This zoonotic and intracellular pathogen is exposed to diverse environmental and host stress factors that require an appropriate response to survive. However, the stress tolerance mechanisms used by to persist are not fully understood.

Background: Although F-prostate-specific membrane antigen-1007 (F-PSMA-1007) positron emission tomography/computed tomography (PET/CT) and multiparametric magnetic resonance imaging (mpMRI) are good predictors of prostate cancer (PCa) prognosis, their combined ability to predict prostate-specific antigen (PSA) persistence has not been thoroughly evaluated. In this study, we assessed whether clinical, mpMRI, and F-PSMA-1007 PET/CT characteristics could predict PSA persistence in patients with PCa treated with radical prostatectomy (RP).

Methods: This retrospective study involved consecutive patients diagnosed with PCa who underwent both preoperative mpMRI and PSMA PET/CT scans between April 2019 and June 2022.

Background: The prevalence of obesity has increased significantly in recent years and is a causal risk factor for the development of type 2 diabetes. Moreover, chronic degenerative joint diseases are also triggered by obesity.

Weight Loss: Both obesity-related secondary diseases-type 2 diabetes and chronic degenerative joint disease-can be prevented or at least delayed by lifestyle intervention aimed at weight reduction.

Foot tuberculosis is rarely reported in the literature, with most tuberculosis of the foot being an uncommon manifestation of skeletal tuberculosis. Early diagnosis and timely medical and surgical intervention can significantly reduce morbidity. A 23-year-old male presented with persistent swelling and pain in his right foot for six months, accompanied by a discharging sinus over the affected area in the last week, making weight-bearing increasingly difficult.

Background: Intraductal carcinoma of the prostate cancer (IDC-P), as a specific pathological type in prostate cancer which usually implies a poor prognosis. IDC-P morphology can be divided into two subtypes: Pattern 1, sieve like or loose cribriform structures; Pattern 2, solid or dense cribriform structures. The purpose of the study is to identify the impact of IDC-P and its subtypes on the prognosis of patients undergoing post-operative radiotherapy (PORT) after radical prostatectomy (RP) due to localized prostate cancer(PCa).
