Murine Models and Human Cell Line Models to Study Altered Dynamics of Ovarian Follicles in Polycystic Ovary Syndrome

open access: yesAdvanced Biology, EarlyView.
The manuscript examines preclinical murine and human models to study polycystic ovary syndrome (PCOS), delving into the cellular and molecular mechanisms underlying altered ovarian follicular dynamics. It explores the cellular interactions involved in normal and PCOS ovaries and outlines the current and novel strategies in the search for preclinical ...

Influence of gypsum treatment on extractability of nutrients from soils

open access: yesPlant, Soil and Environment, 2005
In an incubation experiment with 36 soils we tested the influence of application of 3.3 g of CaSO4.2 H2O per kg of soil on extractability of nutrients (P, K, Mg, Ca, Mn, B and S).

Electronic and Geometrical Structure of Potassium doped Phenanthrene [PDF]

open access: yesarXiv, 2011
The geometrical and electronic structure of potassium doped phenanthrene, \ce{K3C14H10}, have been studied by first-principles density functional theory. The main effect of potassium doping is to inject charge in the narrow phenanthrene conduction band, rendering the system metallic.

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture

open access: yesAdvanced Engineering Materials, EarlyView.
Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

Potassium, magnesium and calcium content in individual parts of Phaseolus vulgaris L. plant as related to potassium and magnesium nutrition

open access: yesPlant, Soil and Environment, 2004
In a two-pot experiment of Phaseolus vulgaris L., the influence of K and Mg gradated doses upon K, Mg and Ca content in the pods, stem and leaves was studied. The content of cations changed significantly in individual parts of the plant.
