Lymphatic spread of mesenchymal renal tumor to metastatic parathymic lymph nodes in rat
Rat mesenchymal renal tumor cells (NeDe)
transplanted under the kidney capsule of F344 rats
resulted in metastases in the parathymic lymph nodes.
Tumor cells were isolated from these tumor-bearing
lymph nodes and 106 cells were implanted under the
kidney capsule. Tumor growth after this implantation
could be traced within six days. India ink was implanted
to prove that there is a connection between the lymphatic
vessels of the kidney capsule and the parathymic lymph
nodes. The distribution of the radioligand 18FDG in
different organs also provided evidence that the
parathymic lymph nodes are the primary sites of
metastatic tumor growth. Tumor growth was followed
after staining sections of biopsies of normal, tumorous
kidneys and parathymic lymph nodes embedded in
paraffin. The progression of tumor formation was seen
as a frontline between the healthy and tumor bearing
tissue. This demarcation line was sharp at the beginning
of the invasion and at the peripheral regions of the
tumor, while the central region infiltrated into the
healthy kidney tissue. The initial invasion gradually
turned to an infiltration resulting in the disruption of the
renal tissue, especially at the periphery. Accumulation of
lipids and flow of blood to the lymphatic vessels was
due to the lack of angiogenesis, leading to an increased
pressure of the interstitial fluid. Interstitial damage
ultimately led to the appearance of blood and the growth
of tumor cells in parathymic lymph nodes. The kidney
capsule-parathymic lymph node complex is proposed as
a suitable metastatic model for the isolated in vivo
examination of tumor development and for the analysis
of secondary tumors

B-type natriuretic peptide predicts postoperative cardiac events and mortality after elective open abdominal aortic aneurysm repair
Objective:
The aim of this study was to determine if a single preoperative B-type natriuretic peptide (BNP) level correlated with perioperative cardiac events, cardiac death, and all-cause mortality in elective open abdominal aortic aneurysm (AAA) repair in the short term, intermediate term, and long term.<p></p>
Methods:
A prospective, 2-year multicenter observational cohort study in the three vascular units in Glasgow was performed. All patients who were admitted for elective open AAA repair were recruited. Preoperative BNP levels were performed and batch analyzed at the end of the study. Postoperative screening for cardiac events (nonfatal myocardial infarction and cardiac death) was performed at 2, 5, and 30 days. Follow-up for all-cause mortality was sustained to a minimum of 3 years, where possible.<p></p>
Results:
A total of 106 of 111 patients were recruited. Median BNP concentrations were higher in the 16 patients (15%) with immediate postoperative cardiac events (P = .001) and the five with cardiac death (P = .043). Area under the receiver-operating characteristic (AUC) curve analysis indicated BNP concentrations of 99.5 pg/mL best predicted cardiac events (AUC, 0.927), and 448 pg/mL predicted cardiac death (AUC, 0.963). BNP also predicted all-cause mortality in the short-term (P = .028), intermediate-term (P < .001), and long-term (P < .001) postoperative periods.<p></p>
Conclusions:
Preoperative serum BNP concentration predicted postoperative cardiac events, cardiac death, and all-cause mortality in patients undergoing elective open AAA repair on short-term, intermediate-term, and long-term follow-up on an individual basis with greater accuracy than currently available risk prediction tools.<p></p>

EXCAVATIONS AT THE DARBAND-I RANIA PASS, KURDISTAN REGION OF IRAQ: REPORT ON THE 2016 AND 2017 SEASONS
International audienceThis paper presents the results of the work of the new field initiative launched by the British Museum at the Darband-i Rania pass in the Kurdistan Region of Iraq. The pass is located at the northeastern corner of Lake Dokan, where, though now subsumed into the lake, the Lower Zab flows from the Peshdar into the Rania Plain. It is a strategic location on a major route from Mesopotamia into Iran, and control of both the road and the river must always have been important. The aim of the work, which commenced in autumn of 2016, is to explore a cluster of sites that commanded the pass, with a particular focus on the first millennium b.c. Excavation is being carried out principally at two sites: Qalatga Darband, a large fortified site at the western end of the pass, and Usu Aska, a fort inside the pass itself. The occupations of these two sites are predominantly Parthian and Assyrian respectively. Smaller operations have also been carried out at Murad Rasu, a multi-period site situated on a headland across the waters on the southern shore of Lake Dokan. The results have included the discovery at Qalatga Darband of a monumental complex built of stone and roofed with terracotta roof tiles containing the smashed remains of Hellenistic statuary. Other features indicative of Hellenistic material culture are Mediterranean-type oil-presses and Corinthian column bases and capitals. At Usu Aska remains are being uncovered of an Assyrian fortification of massive proportions
