Thyroid metastasis of clear renal cell carcinoma: a case report and review of the literature.

The thyroid is a rare site for finding tumor metastases. Renal, colorectal, pulmonary, and mammary origin are the most frequent primary neoplasms. Clinical suspicion, early diagnosis, and active surveillance are important during follow-up.

Gastric Schwannoma: A Rare Cause of Gastric Bleeding.

Gastric schwannomas and gastrointestinal stromal tumors (GISTs) are two types of mesenchymal tumors, which represent a group of rare tumors of the gastrointestinal tract. The differential diagnosis between these two tumors is difficult given their very similar appearance and clinical features. The authors present a case of a 63-year-old man with melena and epigastric pain.

Iatrogenic tracheobronchial rupture in a fragile patient: A case report.

An acute injury of the tracheobronchial system is a rare but potentially life-threatening condition that can be caused by medical procedures. Diagnosis requires a thorough evaluation of the patient's medical history, physical examination, and imaging tests. Identification of a tracheal rupture in patients under sedation or general anesthesia may be difficult, and a strong clinical suspicion is essential.

Contrasting Future Growth of Norway Spruce and Scots Pine Forests Under Warming Climate.

Forests are essential to climate change mitigation through carbon sequestration, transpiration, and turnover. However, the quantification of climate change impacts on forest growth is uncertain and even contradictory in some regions, which is the result of spatially constrained studies. Here, we use an unprecedented network of 1.

Serum integrin accumulation during asthma exacerbation: The role of matrix metalloproteinases.

The inflammation caused by asthma exacerbation can lead to permanent changes in the airways and loss of lung function. Integrins are membrane receptors that interact with components of the extracellular matrix and cell adhesion molecules. It is known that these receptors can be found in soluble form in some conditions such as asthma, but it is unknown if exacerbation during asthma leads to soluble integrins.
