Chemotherapy is a mainstay strategy in the management of cancer. Regrettably, current chemotherapeutic agents are cytotoxic not only to cancer cells but also to healthy cells, resulting in dose-limiting serious side effects. Therefore, many researchers are eager to develop new drug delivery systems that may help to decrease the side effects and the target delivery of chemotherapy to cancer cells. One of the epochal drug delivery systems in this field is based on carbon nanotubes technology. The aim of this work is the dual covalent functionalization of single-walled carbon nanotubes (SWCNTs) with doxorubicin (DOX) connected with acid-labile linkage and mannose (Man) as a targeting agent. The characterization of the developed nano-drug by transmission electron microscopy showed good dispersibility of the functionalized SWCNTs with diameters (6-10) nm. Moreover, the percentage of functionalization was determined by thermogravimetric analysis showing 25% of functionalization in the case of SWNCTs-NHN-DOX (7) andimparts this complex a kind of selectivity for cancer cells that overexpress this type of receptors.Obstructive sleep apnoea (OSA) is a chronic disorder that involves a decrease or complete cessation of airflow during sleep. It occurs when the muscles supporting the soft tissues in the throat relax during sleep, causing narrowing or closure of the upper airway. Sleep apnoea is a serious medical condition with an increased risk of cardiovascular complications and impaired quality of life. Continuous positive airway pressure (CPAP) is the most effective treatment for moderate to severe cases of OSA and is effective in mild sleep apnoea. However, CPAP therapy is associated with the development of several nasal side effects and is inconvenient for the user, leading to low compliance rates. The effects of CPAP treatment on the upper respiratory system, as well as the pathogenesis of side effects, are incompletely understood and not adequately researched. To better understand the effects of CPAP treatment on the upper respiratory system, we developed an in vitro 3D-printed microfluidic platform. A nasal epithelial cell line, RPMI 2650, was then exposed to certain conditions to mimic the in-vivo environment. To create these conditions, the microfluidic device was utilized to expose nasal epithelial cells grown and differentiated at the air-liquid interface. The airflow was similar to what is experienced with CPAP, with pressure ranging between 0-20 cm of H20. Cells exposed to pressure showed decreased barrier integrity, change in cellular shape, and increased cell death (lactate dehydrogenase release into media) compared to unstressed cells. EGFR signaling pathway Stressed cells also showed increased secretions of inflammatory markers IL-6 and IL-8 and had increased production of ATP. Our results suggest that stress induced by airflow leads to structural, metabolic, and inflammatory changes in the nasal epithelium, which may be responsible for developing nasal side-effects following CPAP treatment.We investigate the evolution of multicritical points under pressure and magnetic field in a model described by two 5fbands (calledαandβ) that hybridize with a single itinerant conduction band. The interaction is given by the direct Coulomb and the Hund's rule exchange terms. Three types of orderings are considered two conventional spin density waves (SDWs) and an exotic SDW, i.e., with no magnetic moment formation. The conventional SDWs phases, are characterized bymfβ>mfαandmfα>mfβ, respectively, wheremfαandmfβare the intraband staggered magnetizations. The exotic SDW, which has time reversal symmetry, is described by a purely imaginary order parameter. This phase is related to a band mixing given by the spin-flip part of the Hund's rule exchange interaction. As result, without magnetic field, the phase diagrams of temperature (T) versus pressure (given by the variation of the bandwidth (W)) shows a sequence of phase transitions involving the three phases which gives rise to multicritical points. The presence of the magnetic field (h z ) has drastic effects on part of the phase diagram and the location of the multicritical points.In this paper we perform a high-pressure (HP) study of fergusonite-type HoNbO4. Powder x-ray diffraction experiments andab initiodensity-functional theory (DFT) simulations provide evidence of a phase transition at 18.9(1.1) GPa from the monoclinic fergusonite-type structure (space group I2/a) to another monoclinic polymorph described by space group P21/c. The phase transition is reversible and the HP structural behavior is different than the one previously observed in related niobates. The HP phase remains stable up to 29 GPa. The observed transition involves a change in the Nb coordination number from 4 to 6, and it is driven by mechanical instabilities. We have determined the pressure dependence of unit-cell parameters of both phases and calculated their room-temperature equation of state. For the fergusonite-phase we have also obtained the isothermal compressibility tensor. In addition to the HP studies, we report ambient-pressure Raman and infrared (IR) spectroscopy measurements. We have been able to identify all the active modes of fergusonite-type HoNbO4, which have been assigned based upon DFT calculations. These simulations also provide the elastic constants of the different structures and the pressure dependence of the Raman and IR modes of the two phases of HoNbO4. According toab initiocalculations, the reported phase transition is related to a mechanical instability and a phonon softening.To establish an effective nomogram for predicting in-hospital mortality of COVID-19, a retrospective cohort study was conducted in two hospitals in Wuhan, China, with a total of 4,086 hospitalized COVID-19 cases. All patients have reached therapeutic endpoint (death or discharge). First, a total of 3,022 COVID-19 cases in Wuhan Huoshenshan hospital were divided chronologically into two sets, one (1,780 cases, including 47 died) for nomogram modeling and the other (1,242 cases, including 22 died) for internal validation. We then enrolled 1,064 COVID-19 cases (29 died) in Wuhan Taikang-Tongji hospital for external validation. Independent factors included age (HR for per year increment 1.05), severity at admission (HR for per rank increment 2.91), dyspnea (HR 2.18), cardiovascular disease (HR 3.25), and levels of lactate dehydrogenase (HR 4.53), total bilirubin (HR 2.56), blood glucose (HR 2.56), and urea (HR 2.14), which were finally selected into the nomogram. The C-index for the internal resampling (0.97, 95% CI 0.95-0.98), the internal validation (0.96, 95% CI 0.94-0.98), and the external validation (0.92, 95% CI 0.86-0.98) demonstrated the fair discrimination ability. The calibration plots showed optimal agreement between nomogram prediction and actual observation. We established and validated a novel prognostic nomogram that could predict in-hospital mortality of COVID-19 patients.A 66-year-old woman visited our hospital complaining of shortness of breath during exertion and progressive weakness in all her limb muscles. On admission, we noted muscle weakness in her trunk and in her proximal limb muscles, although, her muscle MRI showed no remarkable findings. However, her serum CK level (2,747U/L) was above the normal range. Histopathological examination of muscle biopsy, performed from the left biceps brachii muscle, revealed immune-mediated necrotizing myopathy (IMNM). Her serum samples were negative for myositis-associated autoantibodies (MAAs), anti-SRP, and HMGCR antibodies. However, as the anti-SS-A antibody level in her serum was high (53.2U/mL), we conducted the salivary gland biopsy and the Schirmer test on her eyes. We found lymphocytes infiltration in her salivary gland tissue, and thus, she was diagnosed with primary Sjögren syndrome (SjS). We also observed necrotizing myopathy associated with the SjS. Following her treatment with oral steroids, her symptoms and CK level improved. Although, inflammatory myositis frequently occurs in association with general collagen diseases, necrotizing myopathy has rarely been observed secondary to SjS. We report here this rare case study along with the review of the relevant literature.

His serum prostate-specific antigen (PSA) level was abruptly increased on December 26, 2014. He was admitted to the neurological department of our hospital on January 14, 2015, because of the appearance of staggering gait and diplopia. Neurological examination revealed marked opsoclonus, limb ataxia and ataxic gait. The patient was diagnosed with paraneoplastic opsoclonus and ataxia caused by prostate cancer relapse. Steroid pulse therapy was initiated and his symptoms, including opsoclonus and ataxia, markedly improved. Although most cases of paraneoplastic opsoclonus precede the discovery of cancer, our case developed symptoms simultaneously with relapse and acute progression of prostate cancer. Paraneoplastic opsoclonus with prostate cancer is rare. Additionally, our case showed excellent response of opsoclonus to steroid therapy without treatment of the underlying disease.

Chaotic behavior and fluctuations in the pathophysiology of schizophrenia also make it challenging to gain a better understanding of the disorder. In this study, we focused on the disorders in a constructive and multi-scale manner, we attempt to elucidate the causal relationships across the hierarchy between schizophrenia-related genes and disease-related behaviors.Inflammatory myopathies are heterogeneous disorders characterized by muscle inflammation. They are frequently accompanied by extra-muscular manifestations that affect the skin, lungs, heart, and joints. Owing to its low prevalence, wide phenotypic heterogeneity, and variable disease course, it is difficult to make clear recommendations for the treatment of inflammatory myopathies. Corticosteroids are administered as first-line treatment based on clinical experience rather than controlled trial findings. Empirically, addition of an immunosuppressive drug might offer a steroid-sparing effect or an additional benefit. Administration of intravenous immunoglobulins has been shown to be effective as second-line treatment. Recently, there has been a growing interest in assessing the potential of several biological agents in the treatment of inflammatory myopathies. There are multiple ongoing clinical trials that will lead to more treatment options for inflammatory myopathies.In the field of neurology, idiopathic inflammatory myopathy has been classified into four sub-categories, namely, dermatomyositis, anti-synthetase syndrome, inclusion body myositis, and immune-mediated necrotizing myopathy (IMNM), based upon histological and serological findings. Among them, IMNM has features similar to muscular dystrophy, and it may thus be difficult to differentiate between these two conditions, not only clinically but also pathologically, especially in chronic cases and pediatric patients. This is partly because the main pathological feature of both IMNM and muscular dystrophy is myofiber necrosis and regeneration. Furthermore, IMNM patients with anti-SRP antibodies tend to have more prominent muscle atrophy, especially in the shoulder girdle, which mimics the muscle involvement pattern in facioscapulohumeral muscular dystrophy. Some IMNM patients with anti-HMGCR antibodies have onset in their childhood or even in infancy, and may be misdiagnosed with muscular dystrophy. On the other hand, some muscular dystrophies have been reported to show more prominent lymphocyte infiltration than others, which may also mislead muscle pathologists.
