Light chain amyloidosis is a devastating disease where immunoglobulin light chains form amyloid fibrils, resulting in organ dysfunction and death. Previous studies have shown a direct correlation between the protein thermodynamic stability and the propensity for amyloid formation for some proteins involved in light chain amyloidosis. Here we investigate the effect of somatic mutations on protein stability and in vitro fibril formation of single and double restorative mutants of the protein AL-103 ...

Intermittent switches between low-frequency fluctuations and steady-state emission are experimentally observed in two bidirectionally coupled semiconductor lasers subject to common Gaussian noise applied to the laser pump currents. The time series analysis reveals power-law scalings typical for on–off intermittency near its onset, with critical exponents of −1 for the mean turbulent length versus noise intensity and −3/2 for probability distribution of laminar phases versus the laminar length. The ...

ABSTRACT Knowledge of target environments in breeding programs is important to better direct the development of germplasm. The objectives of this study were to identify associations among barley ( Hordeum vulgare L.) growing environments to identify mega‐environments to select the best locations to breed barley. Twenty‐seven years of grain yield data from the International Barley Yield Trial (IBYT) conducted by the ICARDA‐CIMMYT Barley Breeding Program, consisting of 750 grain yield trials of two replications ...

Plastics in Colombian marine-coastal ecosystems are being fragmented by various environmental factors, generating microplastics (size < 5 mm), an emerging pollutant that is ingested by marine organisms, representing a threat to ecosystems and potentially also to humans. This study aims to evaluate the incidence of microplastic ingestion by fishes from mangrove ecosystems in Cispata, Colombian Caribbean. The digestive tract content of 302 specimens of 22 fish species were analyzed using the KOH digestion ...

Latin America exhibits one of the highest rates of biodiversity and ecosystem services (ES) loss worldwide along with a remarkable asymmetry in the access to ES benefits (ecosystem services inequality, ESI hereafter). The objective of this manuscript is to propose and validate a conceptual model to understand the links between ESI and ecosystem services supply. First, previous ES frameworks were expanded to acknowledge the role of the unequal access to ES on socio-ecological system dynamics. Second ...

Treatment of facial paralysis in the older population is often relegated to static rather than dynamic reanimation for fear of poor outcomes. This pervasive approach lacks physiologic foundation and is not evidence based. Thus, the authors present an extensive literature review demonstrating weak evidence supporting this misguided concept, followed by detailed outcomes from three centers of the largest reported series to date of patients older than 60 years after reanimation performed using three ...

The treatment of long-standing facial palsy represents a challenge for the reconstructive surgeon. Treatment is based on dynamic procedures such as functional muscle flaps. The benefit of added axonal load has recently been reported. This study describes a two stage technique involving dual innervation of a gracilis muscle flap with initial cross-facial nerve graft (CFNG) followed by free muscle transfer co-apted to both the CFNG and a masseter nerve for facial reanimation.A total of nine patients ...

Elevation of the deep inferior epigastric perforator (DIEP) flap interrupts its superficial venous system, and if drainage through the deep venous system is inadequate the flap may develop congestion. The purpose of this retrospective study was to determine the fate of the congested DIEP flap and to optimize the strategy for its salvage.Thirty-two of 162 patients who underwent unilateral breast reconstruction with a DIEP flap developed venous congestion. For the purpose of outcome analysis, cases ...

Echinococcosis is a frequent hepatic parasitic disease in several countries but it is practically absent in Mexico. A cattle strain of Echinococcus granulosus was identified by RAPD, PCR-RFLP and mitochondrial CO1 gene analysis in an autochthonous case. The parasite was obtained after a laparoscopic excision of a liver cyst from a patient that was symptomatic for 6 years but mis-diagnosed before hospitalization.

The intermittent switches between locked and unlocked states occur more regularly at a certain value of the injecting laser pump current. A shape of probability distribution of the experimental inter-spike-interval fluctuations is used to quantitatively characterize the intermittent ...
