Modular extension of topological orders from congruence representations

We present an efficient method to compute the modular extension of both fermionic topological orders and $\mathbb{Z}_2$-symmetric bosonic topological orders in two spatial dimensions, basing on congruence representations of $\mathrm{SL}_2(\mathbb{Z})$ and its subgroups. To demonstrate the validity of our approach, we provide explicit calculations for topological orders with rank up to 10 for the fermionic cases and up to 6 for the bosonic cases. Along the way, we clarify the relation between fermionic rational conformal field theories, which live on the boundary of the corresponding fermionic topological orders, and modular extensions. In particular, we show that the $\mathrm{SL}_2(\mathbb{Z})$ representation of the R-R sector can be determined from the NS-NS sector using the modular extensions.Comment: 96 pages, no figur

Classification of Fermionic Topological Orders from Congruence Representations

The fusion rules and braiding statistics of anyons in $(2+1)$D fermionic topological orders are characterized by the modular data of a super-modular category. On the other hand, the modular data of a super-modular category form a congruence representation of the $\Gamma_\theta$ subgroup of the modular group $\mathrm{SL}_2(\mathbb{Z})$. We provide a method to classify the modular data of super-modular categories by first obtaining the congruence representations of $\Gamma_\theta$ and then building candidate modular data out of those representations. We carry out this classification up to rank $10$. We obtain both unitary and non-unitary modular data, including all previously known unitary modular data, and also discover new classes of modular data of rank $10$. We also determine the central charges of all these modular data, without explicitly computing their modular extensions.Comment: 32 pages, 2 figures, 6 table

Clinical efficacy and safety of autologous serum intramuscular injection in patients with mild-to-moderate atopic dermatitis: a prospective, open-label, uncontrolled study

Background Autologous blood therapy (ABT) has been used to treat atopic dermatitis (AD) for over a century, even though evidence supporting its efficacy is lacking. We aimed to investigate the effectiveness and safety of autologous serum intramuscular injection (ASIM), which is a modified form of ABT, in treating mild-to-moderate AD. Methods This study was a 12-week, open-label, prospective, uncontrolled trial. Following a 4-week run-in period, 22 out of 25 screened patients received ASIM once a week for 4 weeks in conjunction with standard treatment. The primary outcome measure was the Eczema Area and Severity Index (EASI), while the secondary outcomes included the Scoring Atopic Dermatitis (SCORAD) score, Dermatologic Life Quality Index (DLQI), and patient ratings of pruritus, sleep difficulty, disease status, and treatment effectiveness. Safety parameters were also assessed. Results EASI scores showed a non-statistically significant trend toward improvement during ASIM intervention. Patients with at least a 50% improvement in the EASI score at 4 weeks were older and had lower peripheral eosinophil counts (p<0.05). Secondary endpoints, including the SCORAD score, pruritus, sleep difficulty, and DLQI, demonstrated statistically significant improvements at week 4 compared to baseline (p<0.05). No significant adverse reactions were observed. Conclusions This pioneering study suggests that repeated ASIM may improve the clinical symptoms of mild-to-moderate AD, particularly in terms of pruritus and overall quality of life. However, further research with a larger sample size is required to establish the clinical significance of these findings

Immunoglobulin G Subclass Deficiency is the Major Phenotype of Primary Immunodeficiency in a Korean Adult Cohort

Primary immunodeficiency disease (PID) is a rare disorder in adults. Most often, serious forms are detected during infancy or childhood. However, mild forms of PID may not be diagnosed until later in life, and some types of humoral immunodeficiency may occur in adulthood. The purpose of this study was to identify clinical features of PID in Korean adults. A retrospective study was performed on 55 adult patients who were diagnosed as PID between January 1998 and January 2009 at a single tertiary medical center in Korea. IgG subclass deficiency was the most common phenotype (67%, 37/55), followed by total IgG deficiency (20%, 11/55), IgM deficiency (7%, 4/55), common variable immunodeficiency (2%, 1/55), and X-linked agammaglobulinemia (2%, 1/55). IgG3 and IgG4 were the most affected subclasses. Upper and lower respiratory tract infections (76%) were the most frequently observed symptoms, followed by multiple site infection (11%), urinary tract infection, and colitis. Bronchial asthma, rhinitis, and several autoimmune diseases were common associated diseases. IgG and IgG subclass deficiency should be considered in adult patients presenting with recurrent upper and lower respiratory infections, particularly in those with respiratory allergies or autoimmune diseases

Developmental programming of thermonastic leaf movement

Plants exhibit diverse polar behaviors in response to directional and non-directional environmental signals, termed tropic and nastic movements, respectively. The ways in which plants incorporate directional information into tropic behaviors is well understood, but it is less well understood how non-directional stimuli, such as ambient temperatures, specify the polarity of nastic behaviors. Here, we demonstrate that a developmentally programmed polarity of auxin flow underlies thermo-induced leaf hyponasty in Arabidopsis (Arabidopsis thaliana). In warm environments, PHYTOCHROME-INTERACTING FACTOR 4 (PIF4) stimulates auxin production in the leaf. This results in the accumulation of auxin in leaf petioles, where PIF4 directly activates a gene encoding the PINOID (PID) protein kinase. PID is involved in polarization of the auxin transporter PIN-FORMED 3 to the outer membranes of petiole cells. Notably, the leaf polarity-determining ASYMMETRIC LEAVES 1 (AS1) directs the induction of PID to occur predominantly in the abaxial petiole region. These observations indicate that the integration of PIF4-mediated auxin biosynthesis and polar transport, and the AS1-mediated developmental shaping of polar auxin flow, coordinate leaf thermonasty, which facilitates leaf cooling in warm environments. We believe that leaf thermonasty is a suitable model system for studying the developmental programming of environmental adaptation in plants

Acute urticaria caused by the injection of goat-derived hyaluronidase

Hyaluronidase is a goat testicular protein that hydrolyzes hyaluronic acid, a structural component of the intercellular matrix. It is commonly used as a spreading factor to improve the diffusion of drugs, including local anesthetics and chemotherapeutics. We experienced a 55-yr-old female with generalized urticaria that developed within 1 hr after the epidural injection of hyaluronidase. She had a history of allergic rhinitis, and had suffered from post-herpetic neuralgia and a herniated disc for several years. To relieve her pain, she had been given epidural injections consisting of mepivacaine hydrochloride, triamcinolone acetonide, and morphine sulfate biweekly for one year. Hyaluronidase had been administered several times with these drugs before this episode of generalized urticaria. Skin prick testing showed a positive response to 1,500 IU/mL of hyaluronidase extract, as compared to histamine. The patient's serum hyaluronidase-specific IgE level, determined using an enzyme-linked immunosorbent assay (ELISA), was markedly elevated, as compared to unexposed healthy controls. An IgE immunoblot analysis using hyaluronidase extract and the patient's serum showed IgE binding components at 31 and 21 kDa, whereas no corresponding IgE binding component was found in healthy controls. An ELISA inhibition test showed significant, dose-dependent inhibition with the serial addition of hyaluronidase extract. This is the first case of an IgE-medicated allergic reaction to goat (Naemorhedus goral raddenus) hyaluronidase, demonstrated by skin testing and a specific IgE and immunoblot assay

Antiosteoporosis Activity of New Oriental Medicine Preparation (Kyungokgo Mixed with Water Extract of Hovenia dulcis

Protective effect of new oriental medicine (Kyungokgo mixed with water extract of Hovenia dulcis, KOGHD) was assessed on the bone loss induced mice by ovariectomy. In the in vivo experiments, antiosteoporosis effect of KOGHD was investigated using ovariectomized osteoporosis mice model. After 6 weeks of treatment, the mice were euthanized, and the effect of Kyungokgo (KOG) and KOGHD on body weight, spleen weigh, thymus weight, uterine weight, serum biochemical indicators, bone weight and length, immune cell population, bone morphometric parameters, and histological stains was observed. Our results showed that KOGHD prevented the deterioration of trabecular microarchitecture caused by ovariectomy, which were accompanied by the lower levels of bone turnover markers and immune cell population as evidenced by the inhibition of RANKL-mediated osteoclast differentiation without cytotoxic effect on bone marrow derived macrophages (BMMs). Therefore, these results suggest that the Hovenia dulcis (HD) supplementation in the KOG may also prevent and treat bone loss
