1. 1. Carbonate Ions and Gastric Cancer

   Författare :Roy Ehrnström; Malmö Patologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; ODC; COX-2; inflammation; Wistar rats; duodenogastric reflux; Medicin människa och djur ; proliferation; gastrojejunostomy; carbonate ions; Experimental gastric cancer;

   Sammanfattning : Nearly one million new cases of gastric cancer are diagnosed annually throughout the world. Even though the incidence has fallen dramatically in recent decades, this disease is still the second leading cause of cancer death in a global perspective. LÄS MER

3. 2. Evolutionary and Pharmacological Studies of NPY and QRFP Receptors

   Författare :Bo Xu; Dan Larhammar; Samuel Svensson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neuropeptide Y; genome duplication; Evolution; vertebrate; Pharmacology; Modelling; Kinetics; Bioinformatik; Bioinformatics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Farmaceutisk farmakologi; Pharmaceutical Pharmacology;

   Sammanfattning : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. LÄS MER

4. 3. Hypoxia and differentiation in human neuroblastoma cells

   Författare :Helén Nilsson; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ontogeny; embryology human ; Utvecklingsbiologi; teratologi; embryologi människa ; teratology; cytogenetik; Development biology; cytogenetics; Genetik; Genetics; Medicin människa och djur ; HIF; Medicine human and vertebrates ; MYCN; Hypoxia; differentiation; Neuroblastoma;

   Sammanfattning : The childhood tumour neuroblastoma is derived from immature cells of the sympathetic nervous system, which have become arrested at different maturation stages. Neuroblastoma is a malignancy with a high degree of heterogeneity, and there is a correlation between a poor differentiation status and a more aggressive phenotype. LÄS MER

5. 4. Streptococcal M protein and human C4BP

   Författare :Jenny J Persson; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; Medicin människa och djur ; Medicine human and vertebrates ; human C4BP; M protein; antigenic variation; sequence variability; Streptococcus pyogenes; innate immunity;

   Sammanfattning : Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. LÄS MER

7. 5. Integration of Molecular Biology and Morphology in Effusions with Focus on in situ Detection of Telomerase and its Components

   Författare :Nooreldin Zendehrokh; Malmö Patologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pathological anatomy; Patologi allmän ; patologisk anatomi; Diagnostics; Diagnostik; cancer; TRAP in situ; onkologi; Cytologi; cancerology; oncology; Cytology; Medicin människa och djur ; Medicine human and vertebrates ; General pathology; Telomerase;

   Sammanfattning : Clinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. LÄS MER
