Shoulder instability episodes are observed in high-energy injuries, such as seizures. In this case report, we highlight the management of a failed distal tibial allograft procedure for recurrent shoulder instability in a patient with a bony Bankart lesion and epilepsy. The patient was treated with an iliac crest autograft and a proximal humerus osteochondral allograft procedure.

Gender and culture bias in letters of recommendation for computer science and data science masters programs.

Letters of Recommendation (LORs) are widely utilized for admission to both undergraduate and graduate programs, and are becoming even more important with the decreasing role that standardized tests play in the admissions process. However, LORs are highly subjective and thus can inject recommender bias into the process, leading to an inequitable evaluation of the candidates' competitiveness and competence. Our study utilizes natural language processing methods and manually determined ratings to investigate gender and cultural differences and biases in LORs written for STEM Master's program applicants.

Employing Indirect Adenosine 2 Receptors (AR) to Enhance Osseointegration of Titanium Devices: A Pre-Clinical Study.

The present study aimed to evaluate the effect of dipyridamole, an indirect adenosine 2A receptors (AR), on the osseointegration of titanium implants in a large, translational pre-clinical model. Sixty tapered, acid-etched titanium implants, treated with four different coatings ((i) Type I Bovine Collagen (control), (ii) 10 μM dipyridamole (DIPY), (iii) 100 μM DIPY, and (iv) 1000 μM DIPY), were inserted in the vertebral bodies of 15 female sheep (weight ~65 kg). Qualitative and quantitative analysis were performed after 3, 6, and 12 weeks in vivo to assess histological features, and percentages of bone-to-implant contact (%BIC) and bone area fraction occupancy (%BAFO).

High prevalence of intermediate resistance to ciprofloxacin in Salmonella enterica isolated from a Brazilian poultry production chain, located in Minas Gerais state.

We characterized the distribution and diversity of antimicrobial-resistance Salmonella enterica isolated from a poultry production chain in Minas Gerais, Brazil, with special attention to ciprofloxacin and multidrug resistance (MDR). S. enterica (n = 96) of different serotypes and from different processing steps were subjected to broth dilution assay to estimate the minimum inhibitory concentration (MIC) for 12 antibiotics (8 classes) and screened using PCR for the presence of 17 antimicrobial-resistance genes.

Two-temperature molecular dynamics simulations of crystal growth in a tungsten supercooled melt.

In this work we use the two-temperature model (TTM) coupled to molecular dynamics (MD) with sinks at the boundaries of the electronic subsystem to study crystal-growth rate in a quasi-one-dimensional tungsten crystal into a supercooled melt. The possibility of varying the extension of the electronic grid along with the sinks allows a more realistic description of the electronic thermal transport away from the system, providing a considerable heat dissipation from the crystallization front. Based on this approach, our results regarding crystal-growth rates are not affected even if the size of the system is changed.

Large coupling-strength expansion of the Møller-Plesset adiabatic connection: From paradigmatic cases to variational expressions for the leading terms.

We study in detail the first three leading terms of the large coupling-strength limit of the adiabatic connection that has as weak-interaction expansion the Møller-Plesset perturbation theory. We first focus on the H atom, both in the spin-polarized and the spin-unpolarized cases, reporting numerical and analytical results. In particular, we derive an asymptotic equation that turns out to have simple analytical solutions for certain channels.

Phenotypic and genotypic characterization of non-typhoidal Salmonella isolated from a Brazilian pork production chain.

Pork products are important sources of foodborne non-typhoidal Salmonella in Brazil where antibiotics are commonly used throughout the pork production process and this has the potential to selectively favor antibiotic-resistant strains. We characterized the genotypic and phenotypic diversity of S. enterica isolates (n = 41) that were isolated in Brazil.

Kohn-Sham equations with functionals from the strictly-correlated regime: investigation with a spectral renormalization method.

We re-adapt a spectral renormalization method, introduced in nonlinear optics, to solve the Kohn-Sham (KS) equations of density functional theory, with a focus on functionals based on the strictly-correlated electrons (SCE) regime, which are particularly challenging to converge. Important aspects of the method are: (i) the eigenvalues and the density are computed simultaneously; (ii) it converges using randomized initial guesses; (iii) easy to implement. Using this method we could converge for the first time the Kohn-Sham equations with functionals that include the next leading term in the strong-interaction limit of density functional theory, the so called zero-point energy (ZPE) functional as well as with an interaction-strength-interpolation functional that includes both the exact SCE and ZPE terms.
