CAN STELLAR ROTATION SHAPE THE PLANETARY NEBULAE

We present a new scenario for bipolar PNe formation based on the effects of the stellar rotation on the stellar radiation field. We suggest that in the early stages of the evolution of a planetary nebula, its central star increases its rotational velocity and, due to the gravitational darkening or a possible formation of an equatorial disk, creates a bipolar ionization structure in the expelled spherical AGB shell. The reaction of a spherical shell to an axisymmetric radiation field is explored, and we show that the shell is ionized in a bipolar pattern. This is not the fully developed bipolar nebula, but a structure formed in the very early stages of the post-AGB evolution. We speculate that the nuclear region of an AGB star is contracted at the end of the thermonuclear reactions. This stellar remnant partially conserves its angular momentum and increases its rotational velocity by about 2 orders of magnitude. Thus, the proto-CSPN first has axisymmetric radiation field due to the gravitational darkening, and then its wind is axisymmetric. The radiation field forms a bipolar structure which eventually evolve to a typical bipolar nebula. The proposed idea is based on the observed characteristics of the B[e] stars among which are several CSPN (Lamers & Cassinelli 1999).
Psychosocial Determinants of Hand Hygiene, Facemask Wearing, and Physical Distancing During the COVID-19 Pandemic: A Systematic Review and Meta-analysis

Abstract Background Hand hygiene, facemask wearing, and physical distancing play a crucial role in the prevention of the COVID-19 pandemic. Identifying the key psychosocial determinants of these precautionary behaviors contributes to effective intervention and policymaking for COVID-19 and future pandemics. Purpose This study aimed to systematically review and meta-analyze available evidence on psychosocial determinants of the general population’s practice of three precautionary behaviors, based on the Risk, Attitudes, Norms, Abilities, and Self-regulation (RANAS) framework. Methods Literature was identified by searching seven databases and relevant review papers. Observational and experimental studies targeting the general population (≥18 years) published between January 2020 to September 2021 were included. Pooled effect sizes were calculated with the inverse-variance method using random-effects models. Results A total of 51 studies (64 samples) were included in the qualitative synthesis, of which 30 studies (42 samples) were included in the meta-analysis. RANAS-based constructs including knowledge, pros attitudes, and perceived norms were identified as significant determinants of all three behaviors in the meta-analysis. Perceived susceptibility and cons attitudes showed no significant associations with any behaviors. Perceived severity, perceived control, self-efficacy, and behavioral intention were significantly associated with one or two behaviors. Country (western vs. eastern hemispheres) significantly moderated the effects of certain risk and ability factors. Conclusions More research is needed with respect to the intention–behavior relationship, self-regulatory and reflexive factors of precautionary behaviors, as well as the exploration of the potential moderating effect of sociodemographic factors.
PTPA variants and impaired PP2A activity in early-onset parkinsonism with intellectual disability

Abstract The protein phosphatase 2A complex (PP2A), the major Ser/Thr phosphatase in the brain, is involved in a number of signalling pathways and functions, including the regulation of crucial proteins for neurodegeneration, such as alpha-synuclein, tau and LRRK2. Here, we report the identification of variants in the PTPA/PPP2R4 gene, encoding a major PP2A activator, in two families with early-onset parkinsonism and intellectual disability. We carried out clinical studies and genetic analyses, including genome-wide linkage analysis, whole-exome sequencing, and Sanger sequencing of candidate variants. We next performed functional studies on the disease-associated variants in cultured cells and knock-down of ptpa in Drosophila melanogaster. We first identified a homozygous PTPA variant, c.893T>G (p.Met298Arg), in patients from a South African family with early-onset parkinsonism and intellectual disability. Screening of a large series of additional families yielded a second homozygous variant, c.512C>A (p.Ala171Asp), in a Libyan family with a similar phenotype. Both variants co-segregate with disease in the respective families. The affected subjects display juvenile-onset parkinsonism and intellectual disability. The motor symptoms were responsive to treatment with levodopa and deep brain stimulation of the subthalamic nucleus. In overexpression studies, both the PTPA p.Ala171Asp and p.Met298Arg variants were associated with decreased PTPA RNA stability and decreased PTPA protein levels; the p.Ala171Asp variant additionally displayed decreased PTPA protein stability. Crucially, expression of both variants was associated with decreased PP2A complex levels and impaired PP2A phosphatase activation. PTPA orthologue knock-down in Drosophila neurons induced a significant impairment of locomotion in the climbing test. This defect was age-dependent and fully reversed by L-DOPA treatment. We conclude that bi-allelic missense PTPA variants associated with impaired activation of the PP2A phosphatase cause autosomal recessive early-onset parkinsonism with intellectual disability. Our findings might also provide new insights for understanding the role of the PP2A complex in the pathogenesis of more common forms of neurodegeneration.
A Note on Infinite Symmetries of a Free Scalar on AdS Backgrounds and the Breitenlohner-Freedman Bound

We construct infinite dimensional symmetries of a complex, free scalar field on curved space-times generated by isometries of the space-time. We use the Anti de-Sitter backgrounds as an example and check that the boundary terms appearing in the Noether current satisfy the requirement of Noether's theorem that they vanish at the boundary.
Induced-ovulation in female dromedary camel involves kisspeptin neuron activation by β nerve growth factor

Abstract The dromedary camel (Camelus dromedarius) is a short-day desert breeder in which female ovulation is induced by mating. Current data indicate that male-induced ovulation is triggered by its seminal plasma nerve growth factor beta (β-NGF), but the exact mechanisms involved in the induction of ovulation are still unknown. In this study, we report that an intramuscular injection of β-NGF in sexually active short-day-adapted female camels induces an ovulation attested by a surge of circulating LH (2–6 h after treatment) followed by an oocyte release with its cumulus oophorus (confirmed by ultrasonography 72 h after treatment) and a large and progressive increase in circulating progesterone (significant from the 2nd to the 10th days after β-NGF injection). In addition, this β-NGF treatment induces a broad nuclear c-FOS activation in cells located in various hypothalamic areas, notably the preoptic area, the arcuate nucleus, the dorso- and ventromedial hypothalamus, the paraventricular nucleus, and the supraoptic nucleus. A double immunostaining with neuropeptides known to be involved in the central control of reproduction indicates that ∼28% kisspeptin neurons and 43% GnRH neurons in the proptic area, and ∼10% RFRP-3 neurons in the dorso- and ventromedial hypothalamus are activated following β-NGF injection. In conclusion, our study demonstrates that systemic β-NGF induces ovulation in the female dromedary camel and indicates that this effect involves the central activation of hypothalamic neurons, notably the kisspeptin neurons. Summary Sentence In conclusion, our study demonstrates that systemic β-NGF induces ovulation in the female dromedary camel and indicates that this effect involves the central activation of hypothalamic neurons, notably the kisspeptin neurons. Graphical Abstract
Current approach of juvenile nasopharyngeal angiofibroma: a case series

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor that affects predominantly males and is known by its highly vascular character. We have performed a 3-year retrospective study of patients with JNA surgically treated within the third ENT Department of Prof. Dr. Dorin Hociotă Institute of Phonoaudiology and Functional ENT Surgery, Bucharest, Romania. In all the cases, the patients were investigated both clinically and through medical imaging before surgery and all tumors were embolized. Our study comprised of eight cases, of which seven were solved by endoscopic endonasal approach and one case was treated through a combined endonasal–external approach. JNA should always be managed through a multidisciplinary team (MDT) approach in centers with adequate experience, to gain favorable results.
No differences between adults with and without autism in audiovisual synchrony perception

To facilitate multisensory processing, the brain binds multisensory information when presented within a certain maximum time lag (temporal binding window). In addition, and in audiovisual perception specifically, the brain adapts rapidly to asynchronies within a single trial and shifts the point of subjective simultaneity. Both processes, temporal binding and rapid recalibration, have been found to be altered in individuals with an autism spectrum disorder diagnosis. Here, we used a large adult sample (autism spectrum disorder: n = 75, no autism spectrum disorder: n = 85) to replicate these earlier findings. In this study, audiovisual stimuli were presented in a random order across a range of stimulus onset asynchronies, and participants indicated whether they were perceived simultaneously. Based on the synchrony distribution, their individual temporal binding window and point of subjective simultaneity were calculated. Contrary to previous findings, we found that the temporal binding window was not significantly different between both groups. Rapid recalibration was observed for both groups but did not differ significantly between groups. Evidence of an age effect was found which might explain discrepancies to previous studies. In addition, neither temporal binding window nor rapid recalibration was correlated with self-reported autistic symptoms or sensory sensitivity. Lay abstract It has been known for a long time that individuals diagnosed with autism spectrum disorder perceive the world differently. In this study, we investigated how people with or without autism perceive visual and auditory information. We know that an auditory and a visual stimulus do not have to be perfectly synchronous for us to perceive them as synchronous: first, when the two are within a certain time window (temporal binding window), the brain will tell us that they are synchronous. Second, the brain can also adapt quickly to audiovisual asynchronies (rapid recalibration). Although previous studies have shown that people with autism spectrum disorder have different temporal binding windows, and less rapid recalibration, we did not find these differences in our study. However, we did find that both processes develop over age, and since previous studies tested only young people (children, adolescents, and young adults), and we tested adults from 18 to 55 years, this might explain the different findings. In the end, there might be quite a complex story, where people with and without autism spectrum disorder perceive the world differently, even dependent on how old they are.
Remodeling of the aortic wall layers with ageing

Aim: The authors aimed to evaluate the correlations between the variation of two of the main morphological parameters of the aortic wall (intima and media thicknesses) and ageing. Materials and Methods: Aortic cross sections (base region, cross region, thoracic region, and abdominal region) were collected from 90 cases of all ages died and autopsied in the hospital. Tissue samples were processed using the classical histopathological technique (formalin fixation and paraffin embedding) and stained with Orcein and Goldner’s trichrome. The obtained histological slides were transformed into virtual slides. Intima and media thicknesses were determined on virtual slides using a custom-made software, developed in MATLAB (MathWorks, USA). Results and Discussions: The intima layer underwent an obvious and continuous process of thickening both from the aortic base region to its terminal (abdominal) region and from young ages to old age. The processes were similar in men and women but almost always more pronounced in men than in women. The media layer underwent a thickness reduction process from the aortic base to the terminal (abdominal) region whereas with age, the thickness of the layer increased. This divergent profile of evolution was similar in both men and women but with some variations depending on either topography or ageing. Conclusions: Each of the main layers of the aortic wall revealed dynamic individual evolutionary profiles related to age, gender and topography along the aortic path. Studies must be continued in a more detailed, standardized and integrated way.
Targeting BCL-XL in fibrolamellar hepatocellular carcinoma

Fibrolamellar hepatocellular carcinoma (FLC) is a rare and often lethal liver cancer with no proven effective systemic therapy. Inhibition of the antiapoptotic protein BCL-XL was found to synergize with a variety of systemic therapies in vitro using cells dissociated from patient-derived xenografts (PDX) of FLC or cells dissociated directly from surgical patient resections. As BCL-XL is physiologically expressed in platelets, prior efforts to leverage this vulnerability in other cancers have been hampered by severe thrombocytopenia. To overcome this toxicity, we treated FLC models with DT2216, a proteolysis targeting chimera (PROTAC) that directs BCL-XL for degradation via the von Hippel-Lindau (VHL) E3 ligase, which is minimally expressed in platelets. The combination of irinotecan and DT2216 in vitro on cells directly acquired from patients or in vivo using several xenografts derived from patients with FLC demonstrated remarkable synergy and at clinically achievable doses not associated with significant thrombocytopenia.
Adipose Tissue Remodeling in Pathophysiology.

Rather than serving as a mere onlooker, adipose tissue is a complex endocrine organ and active participant in disease initiation and progression. Disruptions of biological processes operating within adipose can disturb healthy systemic physiology, the sequelae of which include metabolic disorders such as obesity and type 2 diabetes. A burgeoning interest in the field of adipose research has allowed for the elucidation of regulatory networks underlying both adipose tissue function and dysfunction. Despite this progress, few diseases are treated by targeting maladaptation in the adipose, an oft-overlooked organ. In this review, we elaborate on the distinct subtypes of adipocytes, their developmental origins and secretory roles, and the dynamic interplay at work within the tissue itself. Central to this discussion is the relationship between adipose and disease states, including obesity, cachexia, and infectious diseases, as we aim to leverage our wealth of knowledge for the development of novel and targeted therapeutics. Expected final online publication date for the Annual Review of Pathology: Mechanisms of Disease, Volume 18 is January 2023.

The (scarce and circumscribed) culinary content in food-based dietary guidelines around the world: 1991–2021

Abstract Objective: To evaluate the culinary content of key messages contained in food-based dietary guidelines (FBDG) available at the global online repository of the FAO of the UN. Design: Document analysis was conducted in August 2021 with data extraction of key messages explicitly related to cooking present in FBDG. Data were analysed inductively using thematic analysis. Setting: The FAO’s global repository of FBDG. Participants: Not applicable. Results: Just over half (n 39; 53·4 %) of the seventy-three FBDG analysed included at least one key message about cooking. The Latin American and Caribbean FBDG presented the greatest amount and variety of content about cooking in the key messages, whereas the Near East and North America placed less emphasis on cooking. We identified three themes: (i) healthy food preparation (n 35; 61·4 % of the fifty-seven culinary key messages identified); (ii) food hygiene (n 14; 24·6 %) and (iii) the promotion of culinary practices (n 7; 12·3 %). Albania’s key message covered two themes (food hygiene and healthy food preparation) (n 1; 1·8 %). Conclusion: FBDG are official documents that express recommendations for a healthy diet. As most of these recommendations throughout the world include foods that must be cooked prior to consumption, culinary content should gain more visibility and be presented more broadly in these official documents.
Advances toward transformative therapies for tendon diseases

Approved therapies for tendon diseases have not yet changed the clinical practice of symptomatic pain treatment and physiotherapy. This review article summarizes advances in the development of novel drugs, biologic products, and biomaterial therapies for tendon diseases with perspectives for translation of integrated therapies. Shifting from targeting symptom relief toward disease modification and prevention of disease progression may open new avenues for therapies. Deep evidence-based clinical, cellular, and molecular characterization of the underlying pathology of tendon diseases, as well as therapeutic delivery optimization and establishment of multidiscipline interorganizational collaboration platforms, may accelerate the discovery and translation of transformative therapies for tendon diseases. Description Review of scientific, clinical, technical, regulatory, and commercial perspectives will enable transformative therapies for tendon diseases.
Diagnosis and treatment of pudendal and inferior cluneal nerve entrapment syndrome: a narrative review

Abstract Aim Pudendal and inferior cluneal nerve entrapment can cause a neuropathic pain syndrome in the sensitive areas innervated by these nerves. Diagnosis is challenging and patients often suffer several years before diagnosis is made. The purpose of the review was to inform healthcare workers about this disease and to provide a basis of anatomy and physiopathology, to inform about diagnostic tools and invasive or non-invasive treatment modalities and outcome. Methods A description of pudendal and inferior cluneal nerve anatomy is given. Physiopathology for entrapment is explained. Diagnostic criteria are described, and all non-invasive and invasive treatment options are discussed. Results The Nantes criteria offer a solid basis for diagnosing this rare condition. Treatment should be offered in a pluri-disciplinary setting and consists of avoidance of painful stimuli, physiotherapy, psychotherapy, pharmacological treatment led by tricyclic antidepressants and anticonvulsants. Nerve blocks are efficient at short term and serve mainly as a diagnostic tool. Pulsed radiofrequency (PRF) is described as a successful treatment option for pudendal neuralgia in patients non-responding to non-invasive treatment. If all other treatments fail, surgery can be offered. Different surgical procedures exist but only the open transgluteal approach has proven its efficacy compared to medical treatment. The minimal-invasive ENTRAMI technique offers the possibility to combine nerve release with pudendal neuromodulation. Conclusions Pudendal and inferior cluneal nerve entrapment syndrome are a challenge not only for diagnosis but also for treatment. Different non-invasive and invasive treatment options exist and should be offered in a pluri-disciplinary setting.
DNA methylation array analysis for diffuse leptomeningeal glioneuronal tumor with conspicuous hypothalamic mass. A case report

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare glioneuronal neoplasm newly included in the 2016 World Health Organization Classification of Tumors of the Central Nervous System. Owing to the wide spectrum of its histopathological and radiological features, accurate diagnosis can be challenging. Recently, molecular testing including DNA methylation array has been introduced with the possibility of improving diagnostic accuracy and contributing to the subtyping especially for brain tumors with ambiguous histology. Two molecularly distinct subtypes of DLGNT have been reported: methylation class‐1 (MC‐1) with an indolent clinical course and MC‐2, the latter aggressive. Herein, we report a case of a 14‐year‐old girl with a conspicuous hypothalamic mass lesion and diffuse leptomeningeal enhancement on magnetic resonance imaging. Biopsy specimens obtained from the hypothalamic lesion endoscopically were mainly composed of oligodendrocyte‐like cells. However, it was difficult to make a definite diagnosis from these non‐specific histological findings. Thus, DNA methylation array analysis was performed additionally by using formalin‐fixed, paraffin‐embedded tissue, resulting in a diagnosis of “MC‐1 subtype of DLGNT” with a high calibrated score (0.99). Consequently, she was treated conservatively, with neither progression of the tumor nor aggravation of symptoms for the next 12 months. It was concluded that DNA methylation array analysis for DLGNT, a rare glioneuronal tumor, could be a powerful tool not only for accurate diagnosis but also decision‐making in selecting the best treatment.
Evaluating reporting of patient-reported outcomes in peptic ulcer disease: a meta-epidemiological study of randomized controlled trials

ABSTRACT Objectives Peptic ulcer disease (PUD) can significantly affect quality of life (QoL). These QoL outcomes are often patient-reported, and their inclusion in clinical trials supplements efficacy outcomes to provide the patients’ perspective. This assese existing literature for completeness of PRO reporting across randomized controlled trials (RCTs) evaluating PUD. Methods This meta-epidemiological, cross-sectional study that assessed completeness of reporting among RCTs addressing management of PUD. We conducted a comprehensive literature search] to identify RCTs with a PRO as a primary or secondary outcome. These RCTs were assessed for completion of reporting according to the PRO adaptation of CONSORT checklist. RCTs were also assessed for Risk of Bias (RoB) using the Cochrane RoB 2.0 tool. Results Masked, duplicate screening of 829 results = yielded a final sample of 35 RCTs. The average completeness of reporting was 32.9% according to the CONSORT-PRO adaptation. Twenty-one (of 35; 60%) of the RCTs were assessed as having ‘high’ risk of bias and nine (of 35; 25.71%) were assessed as having ‘some concerns’ for risk of bias. Bivariate regression found completeness of reporting to be positively associated with increased PRO follow-up duration, sample size, and studies with conflicts of interest. Conclusion RCTs examining the treatment and prevention of PUD with PROs as an outcome measure have deficient reporting and ‘high’ risk of bias according to the CONSORT-PRO and Cochrane RoB guidelines.
