Hormones and fertility

open access: yesAnnales d'Endocrinologie, 2022
Knowledge about infertility has made enormous progress over the last 40 years. Its different mechanisms have been largely elucidated, in females as well as in males. This allows a better understanding of many causes of infertility. In the past years, pregnancies have been achieved using gametes fertilized outside the body.

EXTENT OF MINERALIZATION ORGANIC FERTILIZER ON SALT AFFECTED SOIL AND THAT IMPLEMENTATION ON TOMATO [PDF]

open access: yes, 2011
Mineralization of organic fertilizers in saline soil is determined by the level of soil salinity. The higher levels of soil salinity, the lower the ability of organic matter mineralization. Evaluation mineralization levels assessed by the content of N,

History of nutrient inputs to the northeastern United States, 1930–2000 [PDF]

open access: yes, 2013
Humans have dramatically altered nutrient cycles at local to global scales. We examined changes in anthropogenic nutrient inputs to the northeastern United States (NE) from 1930 to 2000.

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

open access: yesAdvanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Effects of Long-Term Soil Tillage Practices on Soil Organic C Accumulation Characteristics in Double-Cropped Rice Paddy

open access: yesLand
Unreasonable soil tillage measures have caused a sharp decline in the soil carbon (C) pool capacity of rice (Oryza sativa L.) paddy fields, have reduced soil fertility, and have threatened the safe production of rice. Based on long-term position–location

Substitution of Mineral Fertilizer with Organic Fertilizer in Maize Systems: A Meta-Analysis of Reduced Nitrogen and Carbon Emissions

open access: yesAgronomy, 2020
Organic fertilizer is an effective substitute for mineral fertilizer that improves crop yield and is environmentally friendly. However, the effects of substitution often vary due to complicated interactions among the organic fertilizer substitution rate (

Advanced Oral Delivery Systems for Nutraceuticals

open access: yesAdvanced Healthcare Materials, EarlyView.
Emerging delivery technologies are explored to overcome barriers to oral nutraceutical absorption. Traditional carriers are compared with novel platforms including biodegradable polymers, MOFs, MPNs, and 3D printing. These systems enhance bioavailability, control release, and enable personalized nutrition.

To be or not to be [fertile], that is the question [PDF]

open access: yesBasic and Clinical Andrology, 2016
According to our literature analysis, there are no data focused on spermatozoa emotional representations in childless men and data on the emotional repercussions of a diagnosis of infertility on men are still scarce. Thus, in this work, we investigated what the presence or absence of spermatozoa in the semen symbolize for men.To answer this question ...
