Microbial Community Changes across Time and Space in a Constructed Wetland.

Constructed wetlands are artificial ecosystems designed to replicate natural wetland processes. Microbial communities play a pivotal role in cycling essential elements, particularly sulfur, which is crucial for trace metal fixation and remobilization in these ecosystems. By their response to their environment, microbial communities act as biological indicators of the wetland performance.

Agricultural practices influence soil microbiome assembly and interactions at different depths identified by machine learning.

Agricultural practices affect soil microbes which are critical to soil health and sustainable agriculture. To understand prokaryotic and fungal assembly under agricultural practices, we use machine learning-based methods. We show that fertility source is the most pronounced factor for microbial assembly especially for fungi, and its effect decreases with soil depths.

A Rare Case of Postmenopausal Hirsutism Associated With a Serous Cystadenofibroma of the Ovary.

Hirsutism in females is most commonly associated with polycystic ovarian syndrome, but can also result from congenital adrenal hyperplasia and ovarian tumors like granulosa cell tumors, Sertoli-Leydig cell tumors, and hilus cell tumors. We present a case of a 54-year-old female with hirsutism, diagnosed with ovarian cystadenofibroma. She had a history of premature ovarian failure at the age of 35 and presented with new onset chin and upper lip hair, and scalp hair loss.

Selective anomer crystallization from aqueous solution: Monitoring lactose recovery under mutarotation limitation via attenuated total reflection Fourier-transform spectroscopy and theoretical rate analysis.

Lactose is typically produced via cooling crystallization either from whey or whey permeate (edible grade) or from aqueous solution (pharmaceutical grade). While in solution, lactose is present in 2 anomeric forms, α- and β-lactose. During cooling crystallization under standard process conditions, only α-lactose crystallizes, depleting the solution of α-anomer.

Spatial scale impacts microbial community composition and distribution within and across stream ecosystems in North and Central America.

A mechanistic understanding of factors that structure spatiotemporal community composition is a major challenge in microbial ecology. Our study of microbial communities in the headwaters of three freshwater stream networks showed significant community changes at the small spatial scale of benthic habitats when compared to changes at mid- and large-spatial scales associated with stream order and catchment. Catchment (which included temperate and tropical catchments) had the strongest influence on community composition followed by habitat type (epipsammon or epilithon) and stream orders.
