New discoveries in stem cell biology are making the biology of solid tissues increasingly complex. Important seminal studies demonstrating the presence of damage-resistant cell populations together with new isolation and characterization techniques suggest that stem cells exist in the adult lung. More detailed in vivo molecular and cellular characterization of bronchioalveolar stem cells (BASCs...

Good quality communication skills are not evenly distributed among students in secondary schools. This quantitative study with a quasi-experimental method aims to describe high school students' through STEM-based PBL learning Biology, oral and written PBL-based STEM Biology lessons by gender. The research design is Posttest Only Control Design carried out on class XI of SMAN Terpadu Madani Palu...

Because the lung stem cell field is so new, there remain many unanswered questions that are being addressed regarding the identification, location, and role of exogenous and endogenous stem and progenitor cell populations in growth, regeneration, and repair of the lung. Advancing lung stem cell biology will require multidisciplinary teams and a long term effort to unravel the biologic processes...

Stem cells and their potential applications have become the forefront of scientific, political, and ethical discourse. Whereas stem cells were long accepted as units of development and evolution, it is now becoming increasingly clear that they are also units of oncogenesis. Although the field of stem cell biology is expanding at an astounding rate, the data attained are not readily translatable...

introduction: oxygen tension is one of the most important stimuli in stem cell biology. in this study, we investigate the considerable influence of hypoxia on cx43 gene expression as one of the most important gap junction on the surface of mesenchymal stem cells. methods: mesenchymal stem cells were isolated from c57bl/6 mouse bone marrow and cultured in dmem medium under low oxygen tension (1%...

The aim of the study was to determine the influence of the source material and the applied S. cerevisiae strain on the concentrations of carbonyl fractions in raw spirits. Acetaldehyde was the most common aldehyde found, as it accounted for 88-92% of the total amount of aldehydes. The concentration of acetaldehyde in maize, rye and amaranth mashes was highly correlated with fermentation product...

The objective of this study was to identify the major peptides generated by the in vitro hydrolysis of Amaranthus cruentus protein and to verify the effect of these peptides on the activity of 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMG-CoA reductase), a key enzyme in cholesterol biosynthesis. A protein isolate was prepared, and an enzymatic hydrolysis that simulated the in vivo digestion of...

An investigation was carried out with nine green leafy vegetables (GLV’s) with their popular varieties most commonly grown in India to determine their biochemical composition. Among leafy vegetables ascorbic acid was found maximum in Chenopod cultivar Bathua Local (60.6 mg/100 g fw.) followed by Pusa Bathua -1 (23.0 mg/100g fw.) and spinach cultivar PS-1 (51 mg/100 g fw.). Significantly high le...

Recent findings in stem cell biology have opened a new window in regenerative medicine. The endometrium possesses mesenchymal stem cells (MSCs) called endometrial stem cells (EnSCs) having specific regenerative properties linked to adult stem cells. They contribute in tissue remodeling and engineering and were shown to have immuno-modulating effects. Many clinical trials were undertaken to asce...

Stem cells are stirring great excitement in medical research. Stem cells are characterized by their three special properties of self renewal, differentiation and unspecialized nature. The capacity to differentiate into specialized cell types and be able to give rise to any mature cell type is referred to as potency. Human stem cell research holds an enormous potential and contribute to the unde...
