Background and Objectives: Hepatic resection of noncolorectal metastases appears to be performed with increasing frequency. Reported experience is limited and indications are controversial. Methods: Retrospective review of curative hepatic resection in 32 patients (median age 58 years) during 1970- 1995. The primary tumor was a carcinoid in seven patients, other endocrine tumor in five patients, m
The aim of this study was to compare interstitial laser thermotherapy with excision of a liver tumour. A dimethylhydrazine-induced adenocarcinoma was transplanted (implanted if not stated otherwise) into the left lateral lobe of the rat liver, and treatment was performed 8 days later. In the main experiment, rats were treated with resection of the tumour-bearing robe or underwent interstitial lase
Transient hepatic arterial occlusion causes necrosis in solid hepatic tumors in the rat, but regrowth of tumor cells and capillaries takes place from the tumor periphery. It was therefore considered of interest to combine this treatment with the angiogenesis inhibitor TNP-470 (therapeutic model). Wistar rats with a dimethylhydrazine-induced adenocarcinoma implanted into the liver received one of t
Background/Aims: The aim was to investigate the effect of blood inflow occlusion on lesion size and ultrasonographic findings during interstitial laser thermotherapy of normal liver. Methodology: Pigs were treated with or without hepatic inflow occlusion at a laser power of 3 W or without inflow occlusion at 5 W (target temperature 43°C). The thermotherapy system consisted of an Nd:YAG laser and a
Objective: To examine the effect of different temperatures and exposure times in interstitial laser thermotherapy. Design: Controlled laboratory study. Setting: University hospital, Sweden. Material: 48 male Wistar FU rats with dimethylhydrazine-induced adenocarcinoma transplanted into the liver. Intervention: Treatment was given with an Nd:YAG laser and a feedback system for temperature regulatio
This is a prospective pilot investigation of interstitial laser treatment. Twelve patients were treated at 13 sites: seven patients had metastatic or primary liver cancer (with a total of 21 tumour nodules), two had pancreatic carcinoma and four patients had disease at other sites. Treatments mere performed with an Nd-YAG laser, using a high power (6 or 10 W), short-time (5 min) technique or a fee
The fetal to adult switch in hematopoietic stem cell (HSC) behavior is characterized by alterations in lineage output and entry into deep quiescence. Here we identify the emergence of megakaryocyte (Mk) biased HSCs as an event coinciding with this developmental switch. Single-cell chromatin accessibility analysis reveals a ubiquitous acquisition of Mk lineage priming signatures in HSCs during the
Accurate streamflow simulation is crucial for many applications, such as optimal reservoir operation and irrigation. Conceptual techniques employ physical ideas and are suitable for representing the physics of the hydrologic model, but they might fail in competition with their more advanced counterparts. In contrast, deep learning (DL) approaches provide a great computational capability for stream
The refusal to shake hands with a female reporter by a Muslim politician from the Miljöpartiet resulted in a controversy in Sweden. Together with a number of court cases, it revealed a disparity between the established judicial line and the views of the general public. The Swedish controversy received a response from Denmark, where the ruling coalition introduced new citizenship legislation with a
BackgroundAlthough preterm birth predisposes for cardiovascular disease, recent studies in children indicate normal blood pressure and arterial stiffness. This prospective cohort study therefore assessed blood pressure and arterial stiffness in adolescents born very preterm due to verified fetal growth restriction (FGR).MethodsAdolescents (14 (13–17) years; 52% girls) born very preterm with FGR (p
