Trophic niche partitioning and intraspecific variation in food resource use in the genus Pangasianodon in a reservoir revealed by stable isotope analysis of multiple tissues.

Understanding the mechanism by which non-native fish species integrate into native communities is crucial for evaluating the possibility of their establishment success. The genus Pangasianodon, comprising Pangasianodon gigas and Pangasianodon hypophthalmus, has been introduced into reservoirs, which are non-native habitats, for fishery stock enhancement. P.

A case of pelvic squamous cell carcinoma of unknown primary origin that responded well to radiotherapy and nivolumab.

Squamous cell carcinoma of unknown primary origin in the pelvis is rare. We report a case of a 64-year-old woman with a large osteolytic squamous cell carcinoma of unknown primary origin in the pelvis that presented with p16 expression. The patient presented with leg pain and swelling and was admitted to our hospital.

SAPHO syndrome with a purely osteolytic form: A case report.

SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome is a rare, chronic autoinflammatory disorder that can present with a constellation of cutaneous and osteoarticular symptoms. Osteodestructive lesions are not pathognomonic, whereas hyperostosis and osteitis are the most prominent imaging findings. We report the case of a man with osteolytic changes of the lumbar vertebra and a history of palmoplantar pustulosis.

Fluorodeoxyglucose positron emission tomography (FDG/PET) shows the effect of carbon-ion radiotherapy (CIRT); with pathologic confirmation.

Response evaluation of carbon-ion radiotherapy poses a diagnostic challenge. Due to its functional aspects, fluorodeoxyglucose positron emission tomography (FDG/PET) has a role in the diagnosis of photon radiation therapy. In addition, several studies suggested that FDG/PET may be useful to select the optimal site for performing a diagnostic biopsy.

A case of bulla formation after treatment for COVID-19 pneumonia.

In December 2019, coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was reported in Wuhan, China. An 82-year-old woman presented to our hospital with high fever (39°C) and chest computed tomography revealed ground-glass opacities in the left lung apex. She was positive for SARS-CoV-2 based on a polymerase chain reaction test, and diagnosed with COVID-19 pneumonia.

Synthesis, structure, and fluorescence properties of a calcium-based metal-organic framework.

The solvothermal reaction of a mixture of calcium acetylacetonate and 1,4-naphthalenedicarboxylic acid (HNDC) in a solution containing ethanol and distilled water gave rise to a metal-organic framework (MOF), {(HO)[Ca(NDC)(CHO)(OH)]}·1.1HO. This MOF possesses a new structure composed of calcium clusters and HNDC linker anions and shows a unique fluorescence property; it exhibits a fluorescence peak at 395 nm ( = 350 nm) at room temperature, which is blue-shifted compared with that exhibited by the free HNDC ligand.
