BACKGROUND Androgenic alopecia (AGA) is a major type of human scalp hair loss, which is caused by two androgens: testosterone (T) and 5α-dihydrotestosterone (5α-DHT). Both androgens bind to the androgen receptor (AR) and induce androgen-sensitive genes within the human hair dermal papilla cells (HHDPCs), but 5α-DHT exhibits much higher binding affinity and potency than T does in inducing the in...

Mangrove trees, which develop along tropical coasts, are known to use saline water uptake. In French Guiana, the high salinity condition is the result of seawater evaporation on mud banks formed from the Amazon sediment flumes. In the back mangrove a few kilometres inland, groundwater, soil water and the xylem sap uptake in the trees remain highly salty, and only very tolerant plants like Avice...

Aim: Variety of phylloplane and endophytic fungi is used to imitate as one of the rich source of novel compounds of biological accomplishments and have a high level of organizational diversity on the leaf surfaces. Bioactive composites produced by these phylloplane and endophytes have shown inspiring potentiality towards therapeutic medicine, for which it is necessary to appreciate and employ t...

Mangrove plants comprise plants with similar ecological features that have enabled them to adapt to life between the sea and the land. Within a geographic region, different mangrove species share not only similar adaptations but also similar genetic structure patterns. Along the eastern coast of South America, there is a subdivision between the populations north and south of the continent's nor...

In order to understand the salt tolerance and secretion in mangrove plant species, gel electrophoresis coupled with LC-MS-based proteomics was used to identify key transport proteins in the plasma membrane (PM) and tonoplast fractions of Avicennia officinalis leaves. PM and tonoplast proteins were purified using two-aqueous-phase partitioning and density gradient centrifugation, respectively. F...

It is necessary to monitor and identify mangroves types and spatial extent near coastal areas because it plays an important role in coastal ecosystem and environmental protection. This research aims at identifying and mapping mangroves types along Karachi coast ranging from 24.79 to 24.85 in latitude and 66.91 to 66.97 in longitude using hyperspectral remote sensing data and techniques. Image a...

Mangroves are enriched with various bioactive compounds is an inevitable fact. Almost all the mangroves exhibited good biological activities against human, animal and plant pathogens. In this study, mangrove Avicennia marina screened Plasmodium falciparum. (Forsk)Vierh. evergreen tree found along tropical subtropical coastlines. It well known for being antibacterial, anticancer, antioxidant, an...

Cytochrome c oxidase subunit I (COI) sequences were used to estimate demographic histories of populations of the buckeye butterfly Junonia genoveva (Cramer) from Costa Rica and Mexico. Previous studies have revealed significant structure between populations of J. genoveva from coastal regions of northwestern Mexico, which utilize black mangrove Avicennia germinans (Acanthaceae) as a larval host...

Measurements of gas exchange characteristics were made on intact, attached leaves of hydroponically grown seedlings of Avicennia marina (Forstk.) Vierh. var australasica (Walp.) Moldenke as the NaCl concentration of the culture solution was varied by step changes of 50 millimolar NaCl every 2nd day from 50 to 500 to 50 millimolar NaCl. The CO(2) assimilation rate, stomatal conductance, intercel...
