Bone marrow; Diffuse large B-cell lymphoma

This study aimed to improve understanding of the diagnosis, treatment, and prognosis of primary bone marrow (PBM) diffuse large B-cell lymphoma (DLBCL), a rare illness. We report a 56-year-old man with pancytopenia and hyperbilirubinemia but without lymphadenopathy, hepatomegaly, or splenomegaly. Bone marrow aspiration, flow cytometry, biopsy, and immunohistochemistry confirmed DLBCL. Two ... more

Diffuse large B-cell lymphoma; Head and neck region; Immunohistochemical subtypes

The objectives of this study were to detect immunohis­tochemical subtypes of diffuse large B-cell lymphoma (DLBCL) of the head and neck, to compare the Hans, Choi, and Tally algorithms and to examine the significance of protein expression in these algorithms. This study included 103 DLBCL patients at Sichuan Cancer Hospital between May 2010 and October 2012. Immunohistochemistry was per­ ... more

Glucose transporters; Goat; Mammary gland epithelial cells; SWEET1

SWEETs are a recently discovered class of sugar transporters that mediate glucose uptake in the intestine and mammary glands. Our objectives were to clone goat SWEET1 and conduct a functional analysis of its effect on glucose efflux in goat mammary gland epithelial cells. We cloned and sequenced the goat SWEET1 gene from goat mammary glands, then conducted an analysis of the structure of ... more

Chromatin accessibility; Epigenetic mechanisms; GC-rich DNA; Real-time polymerase chain reaction

In the mammalian genome, approximately 50% of all genes are controlled by promoters with high GC contents. Analyzing the epigenetic mechanisms regulating their expression is difficult. Hence, we examined a method for stable quantification of such GC-rich DNA sequences. Quantification of DNA during real-time PCR is often based on reagent kits containing the fluorescent dye SYBR Green. ... more

The mechanism of dominant follicle selection is unclear because of its physiological complexity. However, some studies have reported that the immune system plays an important role in reproductive physiology. The objective of the current study was to investigate the differential expression of Toll-like receptors (TLRs) in the dominant (DFs) and nondominant follicles (NFs), and to determine the ... more

Tambaqui, Colossoma macropomum, is the main native freshwater fish in Brazilian aquaculture. Therefore, intensive research pressure has been applied to the species to support new technologies for tambaqui farming. Molecular biology represents a tool that can be used to investigate every field of applied biology, from fish physiology to the effects of climate change. Based on the importance of ... more

Intramammary infections are one of the main causes of productivity loss in dairy cows. To better understand the immune system response and to avoid the use of live animals, we validated the use of isolated bovine udder as an ex situ model. Six mammary glands were collected from cows ready for culling. Three udders were perfused with Tyrode's solution and three were not-perfused. During six ... more

Rice is a cereal that presents a great ability to adapt to different soil and climate conditions. However, as it is a tropical crop with C3 metabolism, it performs better in warm temperatures with high solar radiation. Tolerance to stress caused by low temperatures is a highly complex process that involves various metabolic pathways and cellular compartments, resulting in general or specific ... more
