BACKGROUND: Tear recurrence is considered the main complication of a rotator cuff repair. The best arthroscopic technique has not yet been established. The aim of the present study was to evaluate, from a clinical and a radiological standpoint, the all-arthroscopic transosseous rotator cuff repair with cortical lateral augmentation, performed in the setting of a revision surgery. MATERIALS AND METHODS: Eleven consecutive cases were prospectively followed up for a minimum of 12 month after a rotator cuff repair with a novel all-arthroscopic transosseous rotator cuff repair...

Lycopene is a red carotenoid pigment with strong antioxidant activity. Saccharomyces cerevisiae is considered a promising host to produce lycopene, but lycopene toxicity is one of the limiting factors for high-level production. In this study, we used heterologous lycopene biosynthesis genes crtE and crtI from Xanthophyllomyces dendrorhous and crtB from Pantoea agglomerans for lycopene production in S. cerevisiae. The crtE, crtB, and crtI genes were integrated into the genome of S. cerevisiae CEN.PK2-1C strain, while deleting DPP1 and LPP1 genes to inhibit a competing pathway producing farnesol...

REVIEW
Jessica Bear, Natalie Rollick, David Helfet
PURPOSE OF REVIEW: Tibial plafond, or pilon, fractures can be some of the most difficult fractures to manage. As they are often associated with high-energy trauma, both the soft tissue involvement and the comminuted fracture pattern pose challenges to fixation. Furthermore, the complex anatomy and trauma to the cartilage at the time of injury predispose pilon fractures to poor functional outcomes and high rates of posttraumatic arthritis. This review will discuss the recent developments in the treatment of tibial pilon fractures...

Strain elastography is a recently developed ultrasound method that seems to contribute to the diagnosis and monitoring of inflammatory bowel diseases. This pictorial essay aims to present the feasibility of strain elastography in clinical practice by comparing visual observation and semiquantitative parameters with endoscopic or radiological images in some common cases of Crohn's disease. In our opinion, strain elastography with visual observation is easily performed in connection with B-mode ultrasound and color Doppler imaging and may provide relevant information...

REVIEW
Yongfeng Jin, Hao Li
The complexity of neuronal wiring relies on the extraordinary recognition diversity of cell surface molecules. Drosophila Dscam1 and vertebrate clustered protocadherins (Pcdhs) are two classic examples of the striking diversity from a complex genomic locus, wherein the former encodes more than 10,000 distinct isoforms via alternative splicing, while the latter employs alternative promoters to attain isoform diversity. These structurally unrelated families show remarkably striking molecular parallels and even similar functions...

INTRODUCTION: Sleeve gastrectomy (SG) has become one of the most dramatically increasing bariatric procedures worldwide due to its excellent results and impact on the obesity pandemic. Morbid obesity is known to increase the risk of esophageal adenocarcinoma. However, the evolution of gastroesophageal reflux disease (GERD) along with Barrett's esophagus (BE) after SG is of concern since there is little data available. We present a case of esophageal adenocarcinoma after SG with known intestinal metaplasia on preoperative gastroscopy...

The fossil record provides empirical patterns of morphological change through time and is central to the study of the tempo and mode of evolution. Here we apply likelihood-based time-series analyses to the near-continuous fossil record of Neogene planktonic foraminifera and reveal a morphological shift along the Truncorotalia lineage. Based on a geometric morphometric dataset of 1,459 specimens, spanning 5.9-4.5 Ma, we recover a shift in the mode of evolution from a disparate latest Miocene morphospace to a highly constrained early Pliocene morphospace...

BACKGROUND: Global roll-out of rapid molecular assays is revolutionising the diagnosis of rifampicin resistance, predictive of multidrug-resistance, in tuberculosis. However, 30% of the multidrug-resistant (MDR) strains in an eSwatini study harboured the Ile491Phe mutation in the rpoB gene, which is associated with poor rifampicin-based treatment outcomes but is missed by commercial molecular assays or scored as susceptible by phenotypic drug-susceptibility testing deployed in South Africa...

Simple base-pairing rules of complementarity, perfected by evolution for encoding genetic information, provide unprecedented control over the process of DNA self-assembly. These rules allow us to build exquisite nanostructures and rationally design their morphology, fine-tune their chemical properties, and program their response to environmental stimuli. DNA nanostructures have emerged as promising candidates for transporting drugs across various physiological barriers of the body. In this review, we discuss the strategies used to transform DNA nanostructures into drug delivery vehicles...

North America experienced life-threatening outbreaks of enterovirus D68 (EV-D68) in 2014. We retrospectively detected EV-D68 from a child with Wilson's disease in 2008 in Taiwan. After comparing this EV-D68/Taiwan/2008 strain with EV-D68 genomes obtained from the public domain, it was classified as genome type 1-B; it is phylogenetically related to the predominant EV-D68 viruses that circulated in 2009 in Vietnam. It is necessary to strengthen EV-D68 detection globally, including in children with acute liver failure...

The Gram-positive genus Macrococcus is composed of eight species that are evolutionarily closely related to species of the Staphylococcus genus. In contrast to Staphylococcus species, species of Macrococcus are generally regarded to be avirulent in their animal hosts. Recent reports on Macrococcus have focused on the presence of novel methicillin resistance genes in Macrococcus caseolyticus and Macrococcus canis, with the discovery of the first plasmid-encoded methicillin resistance gene in clinical Staphylococcus aureus of probable macrococcal origin generating further interest in these organisms...

BACKGROUND: Aedes aegypti is the principal vector of several important arboviruses. Among the methods of vector control to limit transmission of disease are genetic strategies that involve the release of sterile or genetically modified non-biting males, which has generated interest in manipulating mosquito sex ratios. Sex determination in Ae. aegypti is controlled by a non-recombining Y chromosome-like region called the M locus, yet characterisation of this locus has been thwarted by the repetitive nature of the genome...

Semiconductor-based photocatalytic hydrogen evolution through water splitting is of great importance for tacking the ever-increasing energy concerns. Here, novel visible-light-driven MoS2 /SnNb2 O6 2D/2D nanosheet heterojunction for photocatalytic hydrogen evolution was designed and fabricated by a facile hydrothermal method. The as-prepared 2D/2D heterojunctions not only offer extended visible light absorption range but also accelerate the separation and transfer efficiency of charge carriers owing to the typical 2D interface...

The photocatalytic degradation of ibuprofen with TiO2 nanoparticles (NPs) and UV light and with graphitic carbon nitride (g-C3 N4 ) 2D nanosheets and visible light are proposed and compared as advanced oxidation treatments for the removal of ibuprofen in water. By-products formed with both photocatalytic systems have been tentatively identified based on the results of ultra-high-performance liquid chromatography coupled to high-resolution mass spectrometry, using a quadrupole-time of flight mass spectrometer in positive and negative ionization modes, which allowed to obtain the elementary composition of their precursors and fragment ions...

Terrestrial ecologists and biogeochemists are in direct contact with their objects of study via sense organs evolved in those environments; they hence share a common awareness because they can all see the whole elephant, as in the ancient Indian parable. Pelagic ecologists and biogeochemists on the other hand are the blind men groping different parts of the elephant - the protist-dominated biome of the planet - in attempts to understand its structure and functioning in terms of organism life cycles and the biogenic elements of which they are made...
