Post-mastectomy radiation therapy after breast reconstruction: from historic dogmas to practical expert agreements based on a large literature review of surgical and radiation therapy considerations.

Breast reconstruction (BR) after mastectomy is important to consider for a woman's body image enhancement and psychological well-being. Although post-mastectomy radiation (PMRT) significantly improves the outcome of patients with high-risk breast cancer (BC), PMRT after BR may affect cosmetic outcomes and may compromise the original goal of improving quality of life (QoL). With the lack of practical guidelines, it seems essential to work on a consensus and provide some "expert agreements" to offer patients the best option for PMRT after BR.

Engineering Vacancies for the Creation of Antisite Defects in Chemical Vapor Deposition Grown Monolayer MoS and WS via Proton Irradiation.

It is critical to understand the laws of quantum mechanics in transformative technologies for computation and quantum information science applications to enable the ongoing second quantum revolution calls. Recently, spin qubits based on point defects have gained great attention, since these qubits can be initiated, selectively controlled, and read out with high precision at ambient temperature. The major challenge in these systems is controllably generating multiqubit systems while properly coupling the defects.

Benchmarking the accuracy of structure-based binding affinity predictors on Spike-ACE2 deep mutational interaction set.

Since the start of COVID-19 pandemic, a huge effort has been devoted to understanding the Spike (SARS-CoV-2)-ACE2 recognition mechanism. To this end, two deep mutational scanning studies traced the impact of all possible mutations across receptor binding domain (RBD) of Spike and catalytic domain of human ACE2. By concentrating on the interface mutations of these experimental data, we benchmarked six commonly used structure-based binding affinity predictors (FoldX, EvoEF1, MutaBind2, SSIPe, HADDOCK, and UEP).

The impact of AI-based modeling on the accuracy of protein assembly prediction: Insights from CASP15.

In CASP15, 87 predictors submitted around 11 000 models on 41 assembly targets. The community demonstrated exceptional performance in overall fold and interface contact predictions, achieving an impressive success rate of 90% (compared to 31% in CASP14). This remarkable accomplishment is largely due to the incorporation of DeepMind's AF2-Multimer approach into custom-built prediction pipelines.

mutations associated with neurodevelopmental disorder are located on a short amino acid stretch of the anticodon-binding domain.

Majority of 37 human aminoacyl tRNA synthetases have been incriminated in diverse, mostly recessive, genetic diseases. In accordance with this, we uncovered a novel homozygous valyl-tRNA synthetase 1 () gene variant, leading to p.T1068M mutation.

Molecular Mechanism of Nucleosome Recognition by the Pioneer Transcription Factor Sox.

Pioneer transcription factors (PTFs) have the remarkable ability to directly bind to chromatin to stimulate vital cellular processes. In this work, we dissect the universal binding mode of Sox PTF by combining extensive molecular simulations and physiochemistry approaches, along with DNA footprinting techniques. As a result, we show that when Sox consensus DNA is located at the solvent-facing DNA strand, Sox binds to the compact nucleosome without imposing any significant conformational changes.

Validation of bioelectrical impedance analysis in the evaluation of body composition in patients with breast cancer.

Background: The evaluation of body composition is an essential parameter for preventing obesity and sarcopenic obesity, which are prognostic factors in breast cancer. This study aims to validate the bioelectrical impedance analysis (BIA) of women who are breast cancer survivors by using the dual-energy x-ray absorptiometry (DXA) measurement method.

Methods: This validation study included 104 women without metastasis between 32 and 72 years old (mean 47.

Novel biallelic variants affecting the OTU domain of the gene OTUD6B associate with severe intellectual disability syndrome and molecular dynamics simulations.

Intellectual developmental disorder with dysmorphic facies, seizures, and distal limb anomalies (IDDFSDA) is an autosomal recessive multisystem disorder caused by compound heterozygous or homozygous variants in the gene OTUD6B. Herein, we describe novel pathogenic compound heterozygous variants in OTUD6B identified via whole-exome sequencing in an index case exhibited the severe IDDFSDA phenotype. The potential pathogenicity of the novel frameshift and missense variants in the index case was investigated using in silico tools.

Assessment of the CASP14 assembly predictions.

In CASP14, 39 research groups submitted more than 2500 3D models on 22 protein complexes. In general, the community performed well in predicting the fold of the assemblies (for 80% of the targets), although it faced significant challenges in reproducing the native contacts. This is especially the case for the complexes without whole-assembly templates.

Investigation of novel pharmacological chaperones for Gaucher Disease.

Beta-Glucocerebrosidase (GBA) is a lysosomal protein that is responsible for the hydrolysis of glycosylceramide into glucose and ceramide. Mutations in GBA lead to the accumulation of glycosylceramide in the lysosome causing an enlargement of the spleen and the liver and skeletal deformations. This disease is called Gaucher Disease.

A practical approach for the correction of iatrogenic penile skin loss in children: Scrotal embedding technique.

The aim of this particular study is to determine the efficacy of scrotal embedding technique in children with overly deficient penile shaft skin, which takes advantage of the rich vascular supply of the scrotal layers and provides adequate tissue coverage. We give the operative and clinical details of two consecutive cases for which we preferred scrotal embedding technique to replace deficient penile skin. The mean operative time for the first and second stages was 72.

Videoendoscopic single-port nipple-sparing mastectomy and immediate reconstruction.

Purpose: Single-incision videoendoscopic surgery has recently become popular as a result of the ongoing search for less invasive procedures. The aim of this study was to evaluate the safety and efficacy of endoscopic single-port nipple-sparing mastectomy, axillary lymphadenectomy, and immediate reconstruction in patients with breast cancer.

Patients And Methods: From May 14, 2012 through January 23, 2013, 10 patients underwent videoendoscopic single-port nipple-sparing mastectomy and axillary dissection via a single, limited incision and immediate prosthetic reconstruction.

Lower eyelid reconstruction in a paediatric face: a one-stage aesthetic approach using the versatile temporoparietal fascia flap.

There are many different lower eyelid reconstruction techniques defined in the literature. Almost all of the published techniques have been described on elderly patients and use upper eyelid, periorbital or facial tissues as donor sites. However, in case of a paediatric patient or a young adult who has a crease-free and scarless face, camouflage of the facial donor-site scar is usually impossible.

Major donor area complication after a mandibular reconstruction with an osseous fibular free flap: pseudo-compartment syndrome.

The popularity of the fibular free flap in mandibular reconstructions is persisting, and major donor area complications rarely occur after fibular free flap operations. Still, we have observed a pseudo-compartment syndrome in a 52-year-old patient on the 12th postoperative day after a mandibular reconstruction with a fibular free flap. When an obstruction in the deep venous system (deep vein thrombosis) was observed in the Doppler ultrasound-guided imaging, the patient has been taken to the operating room for an emergency surgery and the donor area has been completely reopened (in the manner of a fasciotomy).

Does hyperbaric oxygen administration before or after irradiation decrease side effects of irradiation on implant sites?

Background: One of the main limitations of implant-based breast reconstruction is the high rate of complications such as capsular contracture and poor aesthetic outcome, due to adjuvant radiotherapy. Hyperbaric oxygen treatment (HBOT) has been used to assist wound healing in the prevention and treatment of the side effects of irradiation. We aimed to investigate this effect of HBOT on the capsule reaction and skin, applied before and after irradiation, following the placement of an implant under the dorsal skin of the rat.

Electrothermal bipolar vessel sealer in endoscope-assisted latissumus dorsi flap harvesting.

LigaSure™ is a new bipolar vascular sealing system commonly used in various fields of surgery. However, no reports have been published about its use in plastic surgery, particularly for endoscopic flap harvesting. In this study, we present the use of LigaSure in endoscope-assisted latissimus dorsi (LD) flap harvesting for breast reconstruction.

Osseous hyperplasia of the glenoid fossa.

Neoplasia and hyperplasia of the temporomandibular joint-related connective tissue are among the rare causes of disc displacement and temporomandibular joint (TMJ) dysfunction. Here we present an unusual case of hyperplasia of the glenoid fossa, treated for TMJ dysfunction.

Association of vascular injury with the proximal side branch and assessment of thrombosis rates in a new microarterial traction model.

The higher rate of anastomotic failure in avulsion injuries has been attributed mostly to the uncertainty in determining the uninjured vessel segment suitable for anastomosis and resection past a proximal branch that has been proposed to achieve good arterial flow. A graded, longitudinal, microarterial traction model in rats has been used to examine the histopathologic aspects of the extent of vascular injury and its association with the proximal side branch. Additionally, anastomoses were performed following traction, and thromboses rates were determined.

Management of airway obstruction in a severe case of juvenile hyaline fibromatosis.

Juvenile hyaline fibromatosis (JHF) is an extremely rare, genetic disease with unknown etiology. It is characterized by cutaneous nodules and flexural joint contractures, along with hypertrophy of the gingival and oral mucosa, which is probably the most striking and morbidity-related feature of the disease. An advanced case of JHF with prominent growth retardation, recurrent respiratory tract infections, and impending upper respiratory tract obstruction due to severe hypertrophy of the oral mucosa and gingiva is presented.
