Giant cellular leiomyoma in the broad ligament of the uterus: A case report.

Background: The treatment of large pelvic masses in postmenopausal women is a challenge in clinical practice. Although ultrasound or magnetic resonance imaging can be used to determine the size and location of the mass, it is still difficult to achieve a preoperative diagnosis. The majority of cellular leiomyomas are diagnosed by histopathology after surgery.

Differential distribution and prognostic value of CD4 T cell subsets before and after radioactive iodine therapy in differentiated thyroid cancer with varied curative outcomes.

Differentiated thyroid cancer is the most frequently diagnosed endocrine tumor. While differentiated thyroid cancers often respond to initial treatment, little is known about the differences in circulating immune cells amongst patients who respond differently. A prospective study of 39 patients with differentiated thyroid cancer was conducted.

[Brain basis of physical pain and social pain].

Increasing studies have provided cognitive and neuron evidence for not only the similarities, but also the differences between physical pain and social pain in the brain basis. Comparing the similarities and differences of the brain basis of physical pain and social pain helps us to clarify the mechanism of the occurrence and change of pain, and provide theoretical evidence for clinical pain treatment. In this review, we summarized studies to delineate the brain mechanisms of physical pain and social pain.

A dual-mode nanoparticle based on natural biomaterials for photoacoustic and magnetic resonance imaging of bone mesenchymal stem cells .

Stem cell imaging is critical to elucidate the homing, distribution, survival, and repair mechanisms and to evaluate the therapeutic effects of engrafted stem cells. Unfortunately, unimodal imaging of stem cells does not simultaneously satisfy all current requirements owing to their intrinsic limitations. Obviously, bimodal or multimodal imaging of stem cells is a promising strategy for circumventing this issue.

Effective tracking of bone mesenchymal stem cells in vivo by magnetic resonance imaging using melanin-based gadolinium nanoparticles.

Tracking transplanted stem cells is necessary to clarify cellular properties and improve transplantation success. In this study, we designed and synthesized melanin-based gadolinium (Gd )-chelate nanoparticles (MNP-Gd ) of ∼7 nm for stem cell tracking in vivo. MNP-Gd possesses many beneficial properties, such as its high stability and sensitivity, shorter T1 relaxation time, higher cell labeling efficiency, and lower cytotoxicity compared with commercial imaging agents.

[Influence of urea formaldehyde resin on pyrolysis of biomass: a modeling study by TG-FTIR].

Pyrolysis is an efficient and recycling way to utilize waste wood-based panels, in which urea-formaldehyde resin (UF) is the main difference between wood-based board and other kinds of biomass. The present paper studied the three main components (cellulose, hemicelluloses, lignin) of poplar wood, in order to effectively and environmentally utilize or dispose of waste wood-based panels with pyrolysis technique, to study the influence of urea formaldehyde resin on pyrolytic characteristic of wood during the process of the pyrolysis of waste wood-based panels, and to in-depth explore the mechanism of the effect of UF on each component of wood. Innovatively, the weight-loss character and gas evolution rule of the model (made from cellulose, xylan and lignin, based on the chemical components stud of poplar wood), the main components as well as the ones mixed with UF were analyzed by TG-FTIR (thermogravimetric analyzer coupled to a Fourier transform infrared spectrometer).
