Cavernous sinus thrombosis (CST) is a rare condition that is usually associated with infections, pregnancy, vasculitis and some types of medication, such as the contraceptive pill and paraneoplastic. Primary Burkitt lymphoma (PBL) of the thyroid gland is very uncommon and the clinical description of such cases has been largely limited to case reports. In this paper, we present a case of CST as the first manifestation of PBL of the thyroid gland. To the best of our knowledge, our patient is the first case report of PBL of the thyroid gland that presents with bilateral CST...

A biochemistry course is a fundamental but important subject in medical education in China. In recent years, the number of international medical students has increased. Curriculum reform in biochemistry teaching is needed because of the knowledge limitations of students, a close linkage of biochemical content with clinics, the shortcomings of lecture-centered teaching, and the requirements for early clinical practice training and competence. In this study, we analyzed a novel curriculum reform, "Hybrid-PBL," which combined problem-based learning (PBL) with biochemistry lectures and was implemented for biochemical teaching at Dalian Medical University (DMU) in China...

Rabbit haemorrhagic disease virus (RHDV) induces a highly contagious and extremely lethal disease that fulfils many requirements of an animal model of fulminant hepatic failure (FHF); however, the pathogenesis of RHD has still not been fully elucidated. Cytokines play an important role in regulation of the immune response and pathogenesis of many diseases, including those caused by viral infections. Furthermore, recent studies indicate a role of the immune response, especially peripheral blood leukocytes (PBL), in the pathogenesis of RHD...

Aerosol-cloud interactions (aerosol indirect effects) play an important role in regional meteorological variations, which could further induce feedback on regional air quality. While the impact of aerosol-cloud interactions on meteorology and climate has been extensively studied, their feedback on air quality remains unclear. Using a fully coupled meteorology-chemistry model, we find that increased aerosol loading due to anthropogenic activities in China substantially increases column cloud droplet number concentration and liquid water path (LWP), which further leads to a reduction in the downward shortwave radiation at surface, surface air temperature and planetary boundary layer (PBL) height...

REVIEW
Jenny Hoffmann, Robert S Ohgami
Hematolymphoid malignancies of the breast are most commonly neoplasms of mature B-lymphocytes, and may arise as a primary disease or by secondary involvement of a systemic disease. Primary breast lymphomas (PBL) account for 0.04-0.5% of breast malignancies, less than 1% of all non-Hodgkin's lymphomas (NHL), and less than 5% of extranodal lymphomas (Lakhani et al., 2012; Swerdlow et al., 2008; Joks et al., 2011; Barişta et al., 2000; Giardini et al., 1992; Brogi and Harris, 1999; Topalovski et al., 1999).(1-7) Secondary breast lymphomas (SBL) are also rare, with an estimated annual incidence of 0...

Recent studies have demonstrated a potential link between mitochondrial DNA (mtDNA) content and cirrhosis or hepatocellular carcinoma (HCC). However, there are few studies evaluating mtDNA content as a noninvasive marker of chronic hepatitis B infection (CHB). In this study, we conducted a case-control study to determine mtDNA content in peripheral blood leukocyte (PBL) samples from 76 CHB cases naïve to antivirus therapy and 96 healthy controls, and then evaluated the association between mtDNA content and baseline serum concentration of HBV markers...

PROBLEM: Good teaching requires spontaneous, immediate, and appropriate action in response to various situations. It is even more crucial in problem-based learning (PBL) tutorials, as the tutors, while directing students toward the identification and attainment of learning objectives, must stimulate them to contribute to the process and provide them with constructive feedback. PBL tutors in medicine lack opportunities to receive feedback from their peers on their teaching strategies. Moreover, as tutorials provide little or no time to stop and think, more could be learned by reflecting on the experience than from the experience itself...

The mTor-inhibitor temsirolimus (TEM) has potent anti-tumor activities on extrahepatic colorectal metastases. Treatment of patients with advanced disease may require portal branch ligation (PBL). While PBL can induce intrahepatic tumor growth, the effect of PBL on extrahepatic metastases under TEM treatment is unknown. Therefore, we analyzed the effects of TEM treatment on extrahepatic metastases during PBL-associated liver regeneration. GFP-transfected CT26.WT colorectal cancer cells were implanted into the dorsal skinfold chamber of BALB/c-mice...

The vascular endothelium interacts with all types of blood cells and is a key modulator of local and systemic inflammatory processes, for example, in the adhesion of blood leukocytes to endothelial cells (EC) and the following extravasation into the injured tissue. The endothelium is constantly exposed to mechanical forces caused by blood flow, and the resulting shear stress is essential for the maintenance of endothelial function. Changes in local hemodynamics are sensed by EC, leading to acute or persistent changes...
