Objective: To investigate the expression and prognostic value of miR-224 expression in patients with diffuse large B-cell lymphoma (DLBCL) who underwent R-CHOP.

Materials And Methods: RT-PCR was used to determine the relative expression of miR-224, in 258 DLBCL patients and 40 normal lymphoid tissue specimens.

Results: MiR-224 expression in DLBCL patients was significantly down-regulated compared to that in negative controls (p < 0.05). The 5-year progression-free survival and overall survival rates were significantly higher in the high-expression level group compared to the low-expression level group (p < 0.05).

Conclusions: MiR-224 expression level is implicated as a prognostic marker for DLBCL patients treated with R-CHOP.

MXenes, have been considered as a new generation anode material in lithium-ion batteries for lower lithium-ion diffusion barriers and superior conductivity. Unfortunately, their structures are prone to aggregation and stacking, hindering further shuttle of lithium ions and electrons, resulting in lower discharge capacity. Therefore, the introduction of interlayer spacers for the preparation of MXene-based hybrids has attracted much attention.

Primary splenic diffuse large B-cell lymphoma (PS-DLBCL) is a rare manifestation of malignant lymphoma. Although DLBCL is the most common subtype of non-Hodgkin lymphoma, primary splenic involvement is uncommon. Additionally, a gastrosplenic fistula at initial presentation is even more rare and poses a diagnostic challenge for the radiologist.

Primary central nervous system lymphoma (PCNSL) is a diffuse, large B-cell lymphoma affecting the brain, spinal cord, leptomeninges, or eyes. A patient with a recurrence of a previous PCNSL manifesting as an isolated vitreoretinal disease without central nervous system (CNS) involvement and a second cerebral recurrence without vitreoretinal involvement has not yet been reported. The patient is an 86-year-old man with PCNSL of the left cerebellum diagnosed at the age of 82 years and treated with suboccipital trepanation and resection of the lesion followed by chemotherapy.

We would like to present a 49-year-old female patient who was presented with a vulva lesion and palpable inguinal lymph nodes who were diagnosed with disseminated multiorgan involvement of high grade diffuse large B-cell lymphoma. The F-fluorodeoxyglucose positron emission tomography computerized tomography imaging showed multiple cervical, axillary, and abdominal lymph nodes, pulmonary nodules as well as gross hypermetabolic vulvar lesion.

Human milk extracellular vesicles (EVs) are crucial mother-to-baby messengers that transfer biological signals. These EVs are reported to survive digestion and transport across the intestine. The mechanisms of interaction between human milk EVs and the intestinal mucosa, including epithelial uptake remain unclear.
