An Elusive Diagnosis: Diffuse Large B-Cell Lymphoma Masquerading as Acute Liver Failure with Persistent Lactic Acidosis.

BACKGROUND Acute liver failure (ALF) associated with malignant lymphoma is a rare condition with non-specific clinical and radiological features. Here, we describe an unusual case of ALF due to DLBCL with an image negative on presentation posing diagnostic difficulty. CASE REPORT A 74-year-old man was admitted to our hospital with abdominal pain.

Contrast-induced Thrombosis in Acute Mild Pancreatitis.

In acute pancreatitis, the most crucial aspect of management falls within the first 48-72 hours, which should be approached in a step-wise order. When steps are skipped or rushed, such as the early use of computed tomography (CT) with contrast in the setting of poor oral intake, the risk of morbidity increases. This is a case when the deleterious effects of contrast worsened the severity of the clinical course, resulting in a higher rate of mortality and longer hospital stay, and escalated the healthcare cost burden.

Non-chromatographic preparative purification of enhanced green fluorescent protein.

Recombinant enhanced green fluorescent protein (eGFP) is used as a marker in numerous applications in biomedical research and diagnostics. For these applications, the macromolecule needs to be provided in a highly purified form. The conventional purification process of eGFP usually consists of multiple subsequent preparative chromatography steps.

B cells and T-lymphocyte subsets of the head-associated lymphoid tissues of the chicken.

The head-associated lymphoid tissues of the chicken, composed of the harderian gland and the conjunctiva-associated lymphoid tissue (CALT), were studied to determine whether changes occurred in lymphocyte subpopulations as chickens age from 1 week to 8 weeks. The B cells and subpopulations of T-lymphocytes of the head-associated lymphoid tissues were identified using in situ immunohistochemical staining. Monoclonal antibodies specific for various lymphocyte surface antigens were used.

Mitogenic responses of the head-associated lymphoid tissues of the chicken.

A blastogenesis microassay employing 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) was adapted to measure blastogenic responses of lymphocytes from the chicken's head-associated lymphoid tissues (i.e., the harderian gland and conjunctiva-associated lymphoid tissue) to T- and B-cell mitogens.
