In late summer-early autumn, trees undergo growth cessation culminating in bud set. For a wide range of plants, including Populus, photoperiod is considered as the primary environmental cue determining timing of growth cessation and shoot to bud transition. However, studies on Populus have revealed temperature influence on seasonal growth cessation and bud set. In this study we examine the role of
Classical methods of characterization such as Total Harmonic Distortion, SMPTE Intermodulation or Difference Frequency Intermodulation, are widely used for electroacoustic device characterization. However, these methods only put in evidence some of the nonlinear effects for arbitrary excitations, resulting in non-ideal transfer functions, or interaction between two frequencies. More complex effect
This work focuses on adsorption of polyions onto oppositely charged surfaces and on responses to the addition of a simple monovalent salt as well as to the polyion length (degree of polymerization). We also discuss possible mechanisms underlying observed differences, of the adsorbed amount on silica surfaces at high pH, between seemingly similar polyions. This involves theoretical modeling, utiliz
The presence of many laminin receptors of the β1 integrin family on most cells makes it difficult to define the biological functions of other major laminin receptors such as integrin α6β4 and dystroglycan. We therefore tested the binding of a β1 integrin-null cell line GD25 to four different laminin variants. The cells were shown to produce dystroglycan, which based on affinity chromatography boun
We employed gene array technology to investigate the effects of alpha 1-antichymotrypsin (ACT), soluble or fibrillar Alzheimer's peptide (A beta(1-42)) alone and the combination of ACT/A beta(1-42) on human astrocytes. Using a 1.2-fold change as significance threshold, 398 astrocyte genes showed altered expression in response to these treatments compared to controls. Of the 276 genes affected by t
The feasibility of administering metoclopramide (MCA) as a radiosensitizer has been evaluated in 23 patients with a pathological or cytological diagnosis of a squamous cell carcinoma of the lung, clinically evaluated as inoperable. All patients received 40-60 Gy radiotherapy fractionated into 1.8 Gy fractions 5 times per week (Monday-Friday). Two MCA treatment regimens were used: (i) MCA at 2 mg/k
I takt med att världen blir allt mer globaliserad ökar möjligheterna för människor att förflytta sig över gränserna. Emellertid ökar även riskerna för att människor far illa och blir utnyttjade för till exempel människohandel. Människohandel är ett globalt och komplext problem och trots att människohandel kan syfta till att utnyttja människor på olika sätt och för olika ändamål har insatserna hittSweden faces a problem that no one could have predicted a few years ago, which is that people are exploited for forced labour in the West. The purpose of this essay is to make reference to both criminal and labour law in order to describe the regulations, the current practice, and to observe the difficulties in implementation that exist when introducing legislation in the campaign against forced l
Purpose: The purpose of this thesis is to investigate how socio-political attitudes, particularly trust in governmental institutions and attitudes towards the world’s future, influence consumer responses to Brand Activism in Germany and Austria. As public trust in government declines and expectations for corporate societal engagement rise at the same time, this research aims to examine the resulti
Background: PhiC31 integrase facilitates efficient integration of transgenes into human and mouse genomes and is considered for clinical gene therapy. However recent studies have shown that the enzyme can induce various chromosomal abnormalities in primary human embryonic cells and mammalian cell lines. The mechanisms involved are unknown, but it has been proposed that PhiC31 attachment sites in t
Background: Several anticancer agents including paclitaxel have an inhibitory effect on angiogenesis. Aims: To compare the overall response rate and time to progression with changes in circulating angiogenic factors during palliative treatment with weekly paclitaxel. Material and methods: Patients with metastatic BC, ECOG 0-2, received weekly paclitaxel, concomitant with trastuzumab if HER2+ BC (n
One third of the patients with estrogen receptor alpha (ER alpha)-positive breast cancer who are treated with the antiestrogen tamoxifen will either not respond to initial therapy or will develop drug resistance. Endocrine response involves crosstalk between ER alpha and TGF beta signaling, such that tamoxifen non-responsiveness or resistance in breast cancer might involve aberrant TGF beta signal
Oncogenetic events and unique phenomena of the tumor microenvironment together induce adaptive metabolic responses that may offer new diagnostic tools and therapeutic targets of cancer. Hypoxia, or low oxygen tension, represents a well-established and universal feature of the tumor microenvironment and has been linked to increased tumor aggressiveness as well as resistance to conventional oncologi
The thermal performance curve (TPC) of an organism captures how population growth depends on temperature. When populations experience increased temperatures, such as during global climate change, one prediction is that their TPC can evolve to accommodate the new environmental temperature. Although studies on TPC evolution have mostly focused on modifications in population growth rates, TPC evoluti
The assessment of residual lymphovascular invasion (LVI) in breast cancer patients undergoing neoadjuvant therapy may be a critical factor influencing prognosis and treatment decisions. However, there is a notable discrepancy between the RCB, UICC/AJCC, and ICCR guidelines regarding how LVI should be evaluated and reported in this context. ICCR recommends including LVI in the invasive tumor size f
A meditation on gratitude, strangeness, and listening with careA deceptive cadence suggests resolution but withholds it, opening instead to uncertainty, fragility, and the unexpected. This philosophical-existential inquiry takes that musical figure as a metaphor for life itself—disrupted by illness, sustained by another’s gift, and reshaped by the presence of death. Music here becomes a vital comp
The purpose of this paper is to predict the cost-effectiveness of a preventive health care project based on physical exercise that will take place at Medicon Village, Lund, in the fall of 2016. Data from the Health Survey for England is used to develop an empirical model with individual fixed effects that estimates the relationship between physical exercise and psychological well-being. The freque
Dagens arbetsplats förändras konstant bland annat genom anställdas nytänkande och nyfikenhet. Arbetsmiljöer där anställda känner sig motiverade, en organisation som anställda identifierar sig med och inte minst en arbetsplats där anställda känner sig respekterade och hörda är nyckelfaktorer bakom en organisations framgång. Syftet med denna uppsats är att undersöka om det finns ett samband mellan oThe contemporary workplace undergoes constant transformations, driven in part by employees' innovation and curiosity. Work environments where employees feel motivated, an organization that employees identify with, and notably, a workplace where employees feel respected and heard are key factors behind an organization's success. The purpose of this essay is to investigate whether there is a
Cigarette smoke exposure is a strong risk factor for cardiovascular and respiratory diseases. However, the knowledge about how cigarette smoke induces damage to vasculature and airway is limited. The present study was designed to examine the effects of cigarette smoke particles extracted by heptane (heptane-soluble smoke particles, HSP), by water (water-soluble smoke particles, WSP) and by DMSO (D
Study design: Prospective case series. Objective: To evaluate the effect of three repetitive transforaminal steroid injections in a large series of selected patients with cervical radiculopathy caused by spondylosis. Methods: Consecutively, 140 patients with long-lasting medical history, clinical findings, and MRI indicating a cervical nerve root origin based on degenerative disease and a positive
