Pulmonary Carcinosarcoma: A Rare Disease With Challenging Diagnosis and Treatment.

Pulmonary carcinosarcoma (PCS) is a rare type of non-small cell cancer. Overall, middle-aged and older smokers are the most affected age and sex groups. The diagnosis of PCS is difficult due to the absence of characteristic imaging findings.

A Case Report of Autoimmune Encephalitis: Could Post-COVID-19 Autoimmunity Become a Lethal Health Issue?

While it is primarily thought of as a respiratory illness, COVID-19 is now recognized as a multi-organ disease that can present with a wide range of clinical manifestations. Particularly in patients with severe respiratory illness, neurological manifestations ranging from headaches, and loss of smell to strokes have been associated with the virus. In the setting of resolving respiratory illness, it is important to consider autoimmune encephalitis (AE) in the instance of new-onset neurological manifestations.

Developmental expression of doublesex-related transcripts in the common house spider, Parasteatoda tepidariorum.

Sex determination is a rapidly evolving biological process controlled by differential gene expression. One family of transcription factors that initiate sex-specific gene expression and differentiation in many animal species are the Doublesex and Mab-3 (DM) domain proteins. While much is known about Doublesex-related proteins in various insect orders and commonly studied model systems, little is known about their function in basally branching arthropods.

Acute alcohol prevents the refeeding-induced decrease in autophagy but does not alter the increased protein synthetic response in heart.

Ethanol produces a state of anabolic resistance in skeletal muscle; however, whether the heart displays a similar defect is unknown. Hence, the purpose of this study was to determine the impact of acute ethanol administration on the major signal transduction pathways in the heart that are responsible for regulating the protein synthetic and degradative response to refeeding. Adult male C57Bl/6 mice were fasted for 12 h.
