Cutaneous disseminated sporotrichosis associated with diabetes: A case report and literature review

Plos.org 

by Xiujiao Xia, Huilin Zhi, Zehu Liu

Background

Cutaneous disseminated sporotrichosis (CDS), also called hematogenous sporotrichosis, is a rare condition that usually affects immunocompromised patients. The current work presents the case of a woman with diabetes mellitus associated with CDS.

Case presentation

A 59-year-old woman with diabetes mellitus presented with a two-year history of ulcerated rashes on the left ankle and both sides of the jaw. Physical examination revealed three... Читать дальше...

Review and further developments in statistical corrections for Winner’s Curse in genetic association studies

Plos.org 

by Amanda Forde, Gibran Hemani, John Ferguson

Genome-wide association studies (GWAS) are commonly used to identify genomic variants that are associated with complex traits, and estimate the magnitude of this association for each variant. However, it has been widely observed that the association estimates of variants tend to be lower in a replication study than in the study that discovered those associations. A phenomenon known as Winner’s Curse is responsible for this upward bias present... Читать дальше...

Genome-wide circadian gating of a cold temperature response in bread wheat

Plos.org 

by Calum A. Graham, Pirita Paajanen, Keith J. Edwards, Antony N. Dodd

Circadian rhythms coordinate the responses of organisms to their daily fluctuating environments, by establishing a temporal program of gene expression. This schedules aspects of metabolism, physiology, development and behaviour according to the time of day. Circadian regulation in plants is extremely pervasive, and is important because it underpins both productivity and seasonal reproduction. Circadian regulation extends... Читать дальше...

Exploring tumor-normal cross-talk with TranNet: Role of the environment in tumor progression

Plos.org 

by Bayarbaatar Amgalan, Chi-Ping Day, Teresa M. Przytycka

There is a growing awareness that tumor-adjacent normal tissues used as control samples in cancer studies do not represent fully healthy tissues. Instead, they are intermediates between healthy tissues and tumors. The factors that contribute to the deviation of such control samples from healthy state include exposure to the tumor-promoting factors, tumor-related immune response, and other aspects of tumor microenvironment. Characterizing... Читать дальше...

Maximizing multi-reaction dependencies provides more accurate and precise predictions of intracellular fluxes than the principle of parsimony

Plos.org 

by Seirana Hashemi, Zahra Razaghi-Moghadam, Zoran Nikoloski

Intracellular fluxes represent a joint outcome of cellular transcription and translation and reflect the availability and usage of nutrients from the environment. While approaches from the constraint-based metabolic framework can accurately predict cellular phenotypes, such as growth and exchange rates with the environment, accurate prediction of intracellular fluxes remains a pressing problem. Parsimonious flux balance analysis... Читать дальше...

Asymmetric connections with starburst amacrine cells underlie the upward motion selectivity of J-type retinal ganglion cells

Plos.org 

by Bo Wang, Yifeng Zhang

Motion is an important aspect of visual information. The directions of visual motion are encoded in the retina by direction-selective ganglion cells (DSGCs). ON-OFF DSGCs and ON DSGCs co-stratify with starburst amacrine cells (SACs) in the inner plexiform layer and depend on SACs for their direction selectivity. J-type retinal ganglion cells (J-RGCs), a type of OFF DSGCs in the mouse retina, on the other hand, do not co-stratify with SACs, and how direction selectivity in J-RGCs emerges has not been understood.

The team trying to jumpstart New Hampshire’s oyster populations

After witnessing native oyster reefs dwindle for over two decades, a team of researchers and conservationists from the University of New Hampshire College of Life Sciences and Agriculture are working hard to reverse these trends.

Cessna 208 Caravan

@ Anchorage, AK

May 2023

I always welcome the opportunity to photograph the colorful aircraft of Rust’s Flying Service moored at Lake Hood.  Lake Hood’s oldest and largest seaplane operator, Rust’s was founded in 1963 by retired Air Force Colonel and WWII vet Henry “Hank” Rust.  The types of flights offered by Rust’s range from hunting and fishing to flightseeing tours.  The Cessna 208 Caravan was added to the their fleet in 2007. With a relatively high cruising speed and large windows for scenic tours... Читать дальше...
