A case of classic Hodgkin lymphoma arising after remission of methotrexate-associated follicular lymphoma.

Here we describe our experience with a rare case of methotrexate (MTX)-associated lymphoproliferative disorder (LPD) initially diagnosed as follicular lymphoma (FL) and then in relapse as classic Hodgkin lymphoma (CHL). A 66-year-old man was admitted to the hospital with fever and abdominal and lower back pain after a transient remission of MTX-associated FL (MTX-FL) following MTX withdrawal. Computed tomography (CT) showed para-aortic lymphadenopathy, which was compatible with one of the previous FL lesions.

Prolonged COVID-19 in an Immunocompromised Patient Treated with Obinutuzumab and Bendamustine for Follicular Lymphoma.

A patient with follicular lymphoma treated with obinutuzumab and bendamustine experienced prolonged coronavirus disease-2019 (COVID-19). One month after the symptoms transiently improved, the patient experienced exacerbated COVID-19 symptoms. The patient recovered from COVID-19 with remdesivir and dexamethasone and was discharged 77 days after the disease onset.

Successful Nonsurgical Treatment of Acute Peritonitis Caused by a Large Thrombosis of the Superior Mesenteric Vein in a 25-year-old Woman.

Superior mesenteric venous thrombosis (SMVT), which results from various etiologies, including coagulation disorders, can be diagnosed early using advanced imaging technology. However, few reports have described the nonsurgical treatment of acute peritonitis caused by SMVT. We encountered a young woman whose history included abdominal pain and daily oral contraceptives and who presented with acute peritonitis caused by SMVT.

Mycobacterium chelonae bloodstream infection induced by osteomyelitis of toe: A case report.

Mycobacterium chelonae is a rapidly growing mycobacterium that has the potential to cause refractory infections in humans. Mycobacteremia resulting from the organism is extremely rare, and its clinical features are yet to be uncovered. We herein present a case of M.

Atypical case of posterior reversible encephalopathy syndrome related to late onset postpartum eclampsia: A case report.

Rationale: Eclampsia, an obstetric emergency frequently seen in pregnant or puerperal women, is a risk factor for posterior reversible encephalopathy syndrome (PRES). Most cases of eclampsia occur postpartum. We report a woman with PRES associated with eclampsia 10 weeks post-delivery, the latest onset ever reported.

Rice expression atlas in reproductive development.

Gene expression throughout the reproductive process in rice (Oryza sativa) beginning with primordia development through pollination/fertilization to zygote formation was analyzed. We analyzed 25 stages/organs of rice reproductive development including early microsporogenesis stages with 57,381 probe sets, and identified around 26,000 expressed probe sets in each stage. Fine dissection of 25 reproductive stages/organs combined with detailed microarray profiling revealed dramatic, coordinated and finely tuned changes in gene expression.

AtNUDX1, an 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate pyrophosphohydrolase, is responsible for eliminating oxidized nucleotides in Arabidopsis.

Cellular DNA, RNA and their precursor nucleotides are at high risk of being oxidized by reactive oxygen species. An oxidized base, 8-oxo-7,8-dihydro-2'-(deoxy)guanosine, can pair with both adenine and cytosine, and thus would cause both replicational and translational errors. Previously, we have reported that an Arabidopsis Nudix hydrolase, AtNUDX1, acts to hydrolyze an oxidized deoxyribonucleotide, 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate (8-oxo-dGTP).

Comprehensive analysis of cytosolic Nudix hydrolases in Arabidopsis thaliana.

Nudix hydrolases are a family of proteins that catalyze the hydrolysis of a variety of nucleoside diphosphate derivatives. Twenty-four genes of the Nudix hydrolase homologues (AtNUDTs) with predicted localizations in the cytosol, chloroplasts, and mitochondria exist in Arabidopsis thaliana. Here, we demonstrated the comprehensive analysis of nine types of cytosolic AtNUDT proteins (AtNUDT1, -2, -4, -5, -6, -7, -9, -10, and -11).
