Differential diagnosis of mediastinal cysts: a case series.

Background: Mediastinal cysts are common mediastinal lesions in which diagnostic and therapeutic choices are not always unambiguously presented. Usually, these cysts are asymptomatic and detected by coincidence. The question remains whether, if symptoms are present, the cyst is responsible and whether it should be treated.

Beta-HCG Secretion by a Pulmonary Choriocarcinoma in a Male Patient.

Background: Paraneoplastic secretion of beta-subunit of human chorionic gonadotropin (-HCG) in pulmonary carcinoma is rare. . A 65-year-old man presented with bilateral gynaecomastia with abnormally high levels of -hCG and elevated oestradiol, progesterone, and testosterone levels on April 7, 2023.

Understanding action concepts from videos and brain activity through subjects' consensus.

In this paper, we investigate brain activity associated with complex visual tasks, showing that electroencephalography (EEG) data can help computer vision in reliably recognizing actions from video footage that is used to stimulate human observers. Notably, we consider not only typical "explicit" video action benchmarks, but also more complex data sequences in which action concepts are only referred to, implicitly. To this end, we consider a challenging action recognition benchmark dataset-Moments in Time-whose video sequences do not explicitly visualize actions, but only implicitly refer to them (e.

The photobiology of the human circadian clock.

SignificanceThe function of our biological clock is dependent on environmental light. Rodent studies have shown that there are multiple colors that affect the clock, but indirect measures in humans suggest blue light is key. We performed functional MRI studies in human subjects with unprecedented spatial resolution to investigate color sensitivity of our clock.

The role of neuromodulation in chronic functional constipation: a systematic review.

Background: Chronic functional constipation is a highly prevalent disorder in which, when conservative measures fail to relieve symptoms, surgical interventions are sometimes indicated. In recent years, neuromodulation for the treatment of functional constipation has gained interest but its role and effectiveness are still unclear. The purpose of this review is to provide a systematic overview on the current literature on the different modalities of neurostimulation and their effect on chronic functional constipation in adults as reported in the literature.
