A deep registration method for accurate quantification of joint space narrowing progression in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease that leads to progressive articular destruction and severe disability. Joint space narrowing (JSN) has been regarded as an important indicator for RA progression and has received significant attention. Radiology plays a crucial role in the diagnosis and monitoring of RA through the assessment of joint space.

Morphological and gene expression characterization of , a floral chili pepper mutant caused by a nonsense mutation in .

Unlabelled: Chili peppers are important as vegetables and ornamental crops, because of the variety of fruit shapes and colors. Understanding of flower and fruit development in is limited compared with closely related Solanaceae crops such as tomato. This study reports a novel malformed fruit mutant named (), which was isolated from an ethyl methanesulfonate-induced mutant population of chili pepper.

[A case of small cell lung cancer under hemodialysis with chronic renal failure treated with amrubicin while measuring blood concentration of the drug].

We reported a case of small cell lung cancer treated with amrubicin while receiving hemodialysis. An 83-year-old man with chronic renal failure being treated by hemodialysis was admitted because of a left hilar mass. Small cell lung cancer with liver metastasis (cT2NOM1) was diagnosed.

Downregulation of type II bone morphogenetic protein receptor in hypoxic pulmonary hypertension.

Heterozygous mutations in the type II receptor for bone morphogenetic protein (BMPR-II) and dysfunction of BMPR-II have been implicated in patients with primary pulmonary hypertension (PH). To clarify the possible involvement of BMP and BMPR-II in the development of hypoxic PH, the expression of BMP-2, BMPR-II, and their downstream signals were investigated in rat lung under normal and hypoxic conditions by RT-PCR, immunoblot, and immunohistochemical methods. In rats under normal conditions, BMP-2 is localized in the endothelium of the pulmonary artery, whereas BMPR-II is abundantly expressed in the endothelium, smooth muscle cells, and adventitial fibroblasts.
