Population Dynamics and Their Components

, 2023
AbstractThe Mediterranean has an average annual population growth rate of around 1%, which is about the same as the world population growth rate. With a few rare exceptions, this growth is not principally fuelled by migration flows. However, it is closely linked to the demographic transition still underway in many Southern and Eastern Mediterranean ...

Detection rate for ESR1 mutations is higher in circulating‐tumor‐cell‐derived genomic DNA than in paired plasma cell‐free DNA samples as revealed by ddPCR

Molecular Oncology, EarlyView.
Analysis of ESR1 mutations in plasma cell‐free DNA (cfDNA) is highly important for the selection of treatment in patients with breast cancer. Using multiplex‐ddPCR and identical blood draws, we investigated whether circulating tumor cells (CTCs) and cfDNA provide similar or complementary information for ESR1 mutations.

Morphology of Peripheral Blood Cells from Various Species of Turkish Herpetofauna

Acta Herpetologica, 2010
In this study, measurements of morphological and size parameters of peripheral blood cells (erythrocyte, leucocyte, thrombocyte) on blood smear preparation devices stained with Wright’s stain were given for 87 species from Turkish herpetofauna (19 ...

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

Molecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression

Molecular Oncology, EarlyView.
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...

Adverse prognosis gene expression patterns in metastatic castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
We aggregated a cohort of 1012 mCRPC tissue samples from 769 patients and investigated the association of gene expression‐based pathways with clinical outcomes. Loss of AR signaling, high proliferation, and a glycolytic phenotype were independently prognostic for poor outcomes, and an adverse transcriptional feature score incorporating these pathways ...

Prevalence and factors associated with intention to use contraceptives among women of reproductive age: a multilevel analysis of the 2018 Guinea demographic and health survey

BMC Pregnancy and Childbirth
Background Contraceptive use is a key indicator of improving the health and well-being of women, mothers and their families, preventing unwanted pregnancies, and reducing maternal and child mortalities. Despite a lot of investments from the Government of

Population Bottlenecks in Quasispecies Dynamics

, 2006
The characteristics of natural populations result from different stochastic and deterministic processes that include reproduction with error, selection, and genetic drift. In particular, population fluctuations constitute a stochastic process that may play a very relevant role in shaping the structure of populations.

Polar bear population dynamics in the southern Beaufort Sea during a period of sea ice decline.

Ecological Applications, 2015
In the southern Beaufort Sea of the United States and Canada, prior investigations have linked declines in summer sea ice to reduced physical condition, growth, and survival of polar bears (Ursus maritimus).
