  2. 11. γ-Radiation Induced Synthesis of Metal oxides : Control of Particle Size, Composition, and Morphology

    Author : Zhuofeng Li; Mats Jonsson; Hynd Remita; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; γ-radiation induced synthesis; Metal oxide nanoparticles; Metal oxide nucleation; Mesocrystal formation; Carbon black reactivity towards radical; PVP nanogel.;

    Abstract : Nanomaterials show a significant difference in chemical, mechanical, electronic, magnetic and optical properties compared with bulk counterparts. The synthesis is a key-step to achieve the unique properties of nanomaterials. READ MORE

  4. 12. Surveillance and follow-up of early prostate cancer

    Author : Mats Steinholtz Ahlberg; Anna Bill-Axelson; Lars Holmberg; Anna Lantz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; active surveillance; follow-up; biochemical recurrence; triggers for transition to radical treatment; overdiagnosis; overtreatment.; Urologi; Urology;

    Abstract : Active surveillance (AS) for prostate cancer was introduced to address overtreatment resulting from prostate-specific antigen (PSA) testing. Despite advancements such as Magnetic Resonance Imaging (MRI) and targeted biopsies, PSA remains crucial in prostate cancer diagnostics, leading to ongoing challenges of overdiagnosis and overtreatment.

  5. 13. Neoadjuvant hormone treatment in localized prostate cancer : a clinical and histopathological study

    Author : Magnus Hellström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Localized prostate cancer; radical prostatectomy; neo-adjuvant androgen deprivation; GnRH-agonist; histopathology; immunohistochemistry; image analysis; cancer volume; DNA ploidy patterns; PSA in serum; follow-up; prognosisStockholm 1996;

    Abstract : Surgical treatment of localized prostate cancer may be hampered by the spread of cancer through the prostate capsule and in the surgical margins. The prostate is dependent on androgen hormones for its growth and function. READ MORE

  6. 14. Biophysical studies of ribonucleotide reductase

    Author : Margareta Sahlin; Stockholms universitet; []
    Keywords : ;

    Abstract : Ribonucleotide reductase (EC 1.17.4) catalyses the enzymatic reduction of ribonucleotides to their corresponding deoxyribo- nucleotides, the monomeric precursors for the DNA synthesis in all living cells. All ribonucleotide reductases so far Isolated from different species have been found to contain metal ions, either iron, cobolt or manganese. READ MORE
