We present a case of an aberrant right subclavian artery (ARSA) with extremely rare vascular anomalies.

A 69-year-old woman was suspected to have right internal carotid artery (ICA) stenosis. Computed tomography angiography demonstrated an ARSA and hypoplasia of the right ICA. The proximal segment of the right vertebral artery (VA) was aplasia, and a right type 1 proatlantal artery (PA) arose from the right common carotid artery. Cerebral angiography demonstrated segmental dysplasia of the right ICA. The ascending intrapetrous segment and the ascendingforamen lacerum-horizontal intracavernous segment of the right ICA demonstrated hypoplasia. The collateral pathways promoted reconstitution of each of the distal segments. Left internal carotid angiography demonstrated anterior communicating artery aneurysm and sufficient cross flow to the contralateral middle cerebral artery via the AcomA.

A type 1 PA with an ARSA may result in the regression of the right dorsal aorta with persistence of the first cervical intersegmental artery. Although there are few findings of a relationship between an ARSA and intracranial artery anomalies, a developmental error of the right dorsal aorta may cause such complex vascular anomalies.

Knowledge of anatomical variations in patients with ARSA is useful when performing angiography or endovascular therapy, as well as during clinical follow-up.

To estimate the prevalence of the left-sided aortic arch (LSAA) variants, and the effect of possible moderators on variants' detection.

A systematic online literature search was conducted. The pooled prevalence with 95% confidence intervals was estimated for the typical and atypical branching patterns to compare the overall proportions of different variants. Meta-regression analyses were performed to investigate the effect of the subjects' gender and geographical region, and the multidetector computed tomography (MDCT) scanner's technology on the estimated prevalence.

In total, 18,075 cases from 23 imaging studies were included and 33 different LSAA variants were detected. The estimated heterogeneity was statistically significant. Based on the estimated prevalence, approximately 77% of the population is expected to have the typical branching anatomy with sequence brachiocephalic trunk-left common carotid artery-left subclavian artery, and 23% variant branching patterns. Approximately 71%, 23%, 2%, and 0rch is required.

Dysphagia remains the most significant concern after anti-reflux surgery, including magnetic sphincter augmentation (MSA). The aim of this study was to evaluate postoperative dysphagia rates, its risk factors, and management after MSA.

From a prospectively collected database of all 357 patients that underwent MSA at our institution, a total of 268 patients were included in our retrospective study. Postoperative dysphagia score, gastrointestinal symptoms, proton pump inhibitor intake, GERD-HRQL, Alimentary Satisfaction, and serial contrast swallow imaging were evaluated within standardized follow-up appointments. To determine patients' characteristics and surgical factors associated with postoperative dysphagia, a multivariable logistic regression analysis was performed.

At a median follow-up of 23months, none of the patients presented with severe dysphagia, defined as the inability to swallow solids or/and liquids. 1% of the patients underwent endoscopic dilatation, and 1% had been treated conservativelrisk factor for developing postoperative dysphagia.Site-selective C(sp3)-H functionalizations using photoredox catalysis (PC) and hydrogen atom transfer (HAT) catalysis have received increasing attention. Here, we report a Ph2GeCl2 cocatalyst that greatly improves the yield of α-C(sp3)-H alkylation of primary amines catalyzed by a PC-HAT hybrid system. The α-position of the amino group selectively reacted even when weaker C-H bonds existed in the substrates. This finding may help the design of a novel site-selective hybrid catalysis.Lipid bilayer membranes are indispensable parts of cellular architecture. One of the integral properties of bilayer membranes is the environmental heterogeneity over a wide range of spatiotemporal scales. The environmental heterogeneity is a manifestation of the dynamic and compositional anisotropy in the plane of the membrane as well as along the bilayer normal. Fluorescence lifetime distribution analysis provides a spectroscopic tool to quantitatively characterize such heterogeneities. The review discusses recent applications of fluorescence lifetime distribution analysis utilizing the maximum entropy method to characterize horizontal and vertical heterogeneities in membranes.

High-grade varus osteoarthrosis (OA) is characterized by a pronounced intra-articular varus deformity and associated insufficiency of the lateral ligamentous complex. When performing a total knee arthroplasty (TKA) in such a knee, traditionally the alignment is restored to neutral, and the medial soft tissue structures are released to compensate for the lateral laxity and balance the joint. However, another option would be to leave the medial soft tissues untouched and accept the lateral laxity but to compensate for it using an ML-stabilized constrained-condylar knee (CCK) design. Our aim was to prove our hypothesis that such knees would demonstrate better clinical stability and better functionality as well as subjective outcome scores.

We searched our bicenter database of 912 primary TKAs (from 2016 to 2019) for primary TKA patients with a preoperative varus alignment of > 8°. After inclusion, 60 patients were divided into three groups by implant design CCK (n = 21), posterior-stabilized (PS) (n = 20)lateral laxity in high-grade varus OA knees allowed to refrain from a medial release. CCK designs displayed improved clinical stability and better functionality as well as subjective outcome scores compared to less-constrained designs.A new method of solid-phase reduction magnetic separation with pyrite as a reducing agent was proposed in order to realize resource utilization of high iron bauxite residue while reducing environmental harm. FeS2 powder and high iron bauxite residue powder were uniformly blended and roasted in a closed environment. A magnetic separator was utilized to separate the magnetic iron concentrate at 2400 GS, and the recovery rates were calculated. Experimental results show that the best iron recovery was 91.5% at 16 roasted bauxite residue at 800℃ for 2 h. The recovery of Fe can be improved by reducing high iron bauxite residue with pyrite, and iron in both pyrite and high iron bauxite residue can be recovered simultaneously, alleviating the pressure of iron ore resources and improving its utilization value.In recent years, with the development of the global economy, water pollution has increased. Pollutants migrate, accumulate, and diffuse in aquatic environments. Most of the pollutants eventually enter aquatic organisms. The accumulation of pollutants affects the development and reproduction of organisms, and many pollutants have teratogenic, carcinogenic, and/or mutagenic effects. Aquatic organisms in estuaries and coastal areas are under pressure due to both salinity and pollutants. Among them, salinity, as an environmental factor, may affect the behavior of pollutants in the aquatic environment, causing changes in their toxic effects on fishes. Salinity also directly affects the growth and development of fishes. Therefore, this paper focuses on metals and organic pollutants and discusses the toxic effects of pollutants on fish under different salinities. This research is of great significance to environmental protection and ecological risk assessment of aquatic environments.

To evaluate the performance of chromosomal microarray analysis (CMA) in fetuses with nuchal translucency (NT) > 95th percentile. Secondary objectives were to analyze these results according to NT thickness, below or above 3.5mm, and those without associated anomalies.

This observational single-cohort study was conducted between 2015 and 2018 in fetuses with NT > 95th percentile. Following an invasive test, quantitative fluorescence-polymerase chain reaction (QF-PCR) was performed, and if normal, CMA was performed. Pathogenic copy number variants (CNVs), non-reported pathogenic CNV, pathogenic autosomal recessive variants and variants of unknown significance (VUS) were analysed.

One-hundred and sixty-two fetuses with NT > 95th percentile, normal QF-PCR and CMA were included. Amongst 128 fetuses with NT between the 95th percentile and 3.5mm, one (0.8%) had a pathogenic CNV, four (3.1%) had non-reported pathogenic CNV, one (0.8%) had pathogenic autosomal recessive variant and 13 (10.2%) had VUS. Amongst 34 fetuses with NT ≥ 3.5mm, four (11.8%) had pathogenic CNV, one (2.9%) had non-reported pathogenic CNV, one (2.9%) had pathogenic autosomal recessive variant and four (11.8%) had VUS. Four in 162 (2.5%) fetuses had CNVs at the chromosome 16p13.11 region. Amongst 154 fetuses without structural abnormalities and normal QF-PCR, three (1.9%) had a pathogenic CNV, 5 (3.2%) had non-reported pathogenic CNV, one (0.6%) autosomal recessive pathogenic CNV and 16 (10.4%) had VUS.

Pathogenic CNVs were found in 1% of fetuses with an NT thickness between the 95

percentile and 3.5mm and in 12% of fetuses with NT ≥ 3.5mm. CNVs were found at the 16p13.11 region in 2.5% of cases.

To summarize the clinical characteristics and surgical option of Robert's uterus.

We reported a rare case of Robert's uterus with severe uterine adhesion with successive laparoscopic and hysteroscopic surgery. To our knowledge, such a case has not been reported previously. We also performed a systematic literature review from the PubMed, Embase, and Cochrane databases.

Our patient with Robert's uterus with severe uterine adhesions was successfully treated with hysteroscopic septal resection and hysteroscopic adhesiolysis, and the intractable dysmenorrhea disappeared after the hysteroscopic septal resection. In our study, we analyzed the selected 22 reported cases, 10/22 cases (45.5%) were diagnosed before age 20; 20/22 cases (90.91%) experienced dysmenorrhea, 19/22 cases (86.36%) were with hematometra. 5/22 cases (22.73%) underwent re-operation or a third surgery before diagnosis and management.

Robert's uterus, a rare congenital abnormality of Mullerian duct development, consists of an oblique septum and non-communicating asymmetrical uterine hemi-cavity. The main symptoms are the presence of hematometra and severe dysmenorrhea. Septal resection is the main surgical procedure; however, the rarity and difficulty obtaining a pre-operative diagnosis lead to a high rate of misdiagnosis and second surgery.
