Carrier-free nanodrugs formulated from the supramolecular self-assembly of pure drug molecules have emerged as an innovative and promising strategy for tumor therapy. We report herein a new and simple method to directly assemble a small hydrophobic anticancer drug, 10-hydroxycamptothecin (HCPT), with a photosensitizer chlorin e6 (Ce6) to form stable, discrete nanorods (NRs), which not only circumvent the extreme hydrophobicity of HCPT but also incorporate two different modalities into one delivery system for combination therapy...

Intra-articular entrapment of the medial collateral ligament (MCL) is a rare but recognised complication of traumatic injury to the posteromedial corner (PMC) of the knee. Considering the MCL is the most commonly injured ligament of the knee this complication is extremely rare with only a handful of cases describing MCL entrapment following distal avulsion of the MCL. We present the first known case of MCL entrapment following proximal avulsion of the MCL and posterior oblique ligament (POL) with the mid-substance of the MCL becoming entrapped in the joint, lying on the superior surface of the medial meniscus and extending up into the intercondylar notch...

All-silica Beta zeolite, synthesized by conventional hydroxide route, usually possesses small crystal size of a few hundred nanometers but poor hydrophobicity, whereas the fluoride-mediated one exhibits to be highly hydrophobic but microsized. To obtain nanosized all-silica Beta zeolite with excellent hydrophobicity, an innovative and efficient hydrothermal route via interzeolite transformation for synthesizing all-silica Beta zeolite is proposed in present study. With the assistance of Beta seeds and tetraethylammonium hydroxide as the structure-directing agent, siliceous Beta zeolite is well crystallized at a high solid yield via dissolution-recrystallization of all-silica ITQ-1 crystals at an extremely low water content (H2O/SiO2 molar ratio of 1)...

Subclinical narcissism is a personality trait with two faces: According to social-cognitive theories it is associated with grandiosity and feelings of superiority, whereas psychodynamic theories emphasize vulnerable aspects like fluctuating self-esteem and emotional conflicts. The psychodynamic view, however, is commonly not supported by self-report studies on subclinical narcissism. Personality neuroscience might help to better understand the phenomenon of narcissism beyond the limits of self-report research...

Isolated right superior vena cava drainage into the left atrium (RSVC-LA) is an extremely rare anomaly in the absence of other cardiac or extracardiac abnormalities. The clinical and echocardiographic diagnosis is considered challenging. We report a female infant with cyanosis on crying who was diagnosed as isolated RSVC-LA using conventional and contrast echocardiography, but further confirmation was possible via multidetector CT. The surgical correction was performed with smooth postoperative recovery. In conclusion, isolated RSVC-LA must be in the differential diagnosis of cyanosis in the absence of intracardiac anomalies...

Surgical resection of solid cerebellar hemangioblastomas can be challenging because of the profuse blood supply and tight space. We report two cases of solid cerebellar hemangioblastomas treated via surgical resection with the aid of preoperative endovascular embolization on the day of surgery. Case 1: A 36-year-old woman presented with a two-month history of headache and vomiting. Magnetic resonance imaging(MRI)revealed a right cerebellar solid mass, mild hydrocephalus, and apparent peritumoral edema. Angiogram showed a highly vascularized mass, three feeding arteries from the superior cerebellar artery(SCA), and a dilated vein draining into the confluence...

Two-dimensional (2D) layered hybrid perovskites have shown great potentials in optoelectronics. However, although great efforts have been made, 2D hybrid perovskite ferroelectrics remain rare. Here, we constructed the first ferroelectric with 2D multilayered perovskite framework, (C4H9NH3)2(CH3NH3)2Pb3Br10 (1), by tailored alloying mixed-organic-cations into the prototype of CH3NH3PbBr3. For the first time, concrete ferroelectricity was created by molecular reorientation and synergic ordering of organic cations, which is unprecedented for the known 2D hybrid perovskites...

Beryllium has been considered a superior ablator material for inertial confinement fusion (ICF) target designs. An accurate equation-of-state (EOS) of beryllium under extreme conditions is essential for reliable ICF designs. Based on density-functional theory (DFT) calculations, we have established a wide-range beryllium EOS table of density ρ = 0.001 to 500 g/cm(3) and temperature T = 2000 to 10(8) K. Our first-principle equation-of-state (FPEOS) table is in better agreement with the widely used SESAME EOS table (SESAME 2023) than the average-atom INFERNO and Purgatorio models...

Tuberculosis (TB) accounts for millions of deaths worldwide every year. Diverse survival strategies adopted by Mycobacterium tuberculosis (Mtb) has substantially hindered the existing anti-TB regimen thereby leading to multidrug-resistant (MDR) and extremely drug-resistant (XDR) strains of TB. The steady decrease in current antibiotics' efficacy against these adversities is an indicator that their adequate replenishment in future is almost impossible, placing society on the precipice of a catastrophe. Over the past many years, researchers have been continuously generating new armamentarium of anti-TB drugs by tailoring the properties of available drugs or designing completely new agents...

OBJECTIVES: This work aimed to evaluate semisolid formulations containing topotecan (TPT) loaded nanostructured lipid carriers (NLC) for topical treatment of skin cancers, as TPT is effective against a variety of tumours. A formulation which increases TPT skin permeation would be extremely desirable. METHODS: TPT-NLC were prepared and incorporated in hydrogels with hydroxyethyl cellulose and chitosan (TPT-NLC-HEC and TPT-NLC-Ch, respectively). Control formulations were obtained by dispersing TPT in HEC and Ch hydrogels (TPT-HEC and TPT-Ch)...

The tumor penetration and accumulation of nanoparticle-based drug delivery systems are highly dependent on the particle size. Nanomedicines in the sub-100nm range have been suggested by previous studies to have superior antitumor efficacy on various solid tumors. SN-38 is a very important and highly potent drug for several cancers including colon cancer. However, due to the ultra-flat aromatic structure of SN-38, it is typically very difficult to produce sub-100nm, SN-38-encapsulated nanoparticles without modification of the chemical structure...

The conventional strategies employed for the synthesis of hollow nanofibers (HNFs) require either multistep treatments or special design of the equipment. An additional annealing process is always required, which inevitably consumes more energy and raises the manufacturing cost. In addition, the annealing process may also cause a waste of the matrix materials and the release of toxic gases. Herein, we report for the first time a novel one-step synthesis of hollow hybrid nanofibers via electrospinning. Cellulose was chosen as the polymer matrix, and Fe(OH)3 nanoparticles were grown in situ on the nanofibers during electrospinning...

Primary coronary sinus tumors are extremely rare. Herein, we present a case of a pregnant woman with a primary myxoma in the coronary sinus (CS), which was diagnosed by echocardiography and computed tomography. We reviewed the literature and found two other primary CS tumors. We summarized the gender, ages, symptoms, diagnostic methods, associated anomalies, treatments, histologic findings, and outcomes of the 3 cases. Dyspnea was a common symptom of all 3 patients. Diagnostic methods included echocardiography, computed tomography, magnetic resonance imaging, and coronary angiography...

Necrotizing fasciitis (NF) is a severe bacterial infection with rapid and aggressive progression. The infection generally affects individuals with comorbid conditions that lead to immunologic and microvascular deficiencies. It is characterized by necrosis of tissues, mainly in the extremities, trunk, and perineum, and is rarely found in the head and neck. This case report describes the course of NF in a 55-year-old man, highlighting diagnosis, surgical treatment, drug therapy, and supportive measures. The patient, who had chronic alcoholism, systemic arterial hypertension, a smoking habit, and decompensated diabetes (glucose level of 490 mg/dL), was admitted to the hospital with a volume increase in the cervical and thoracic areas with a duration of about 7 days...

Hypersensitivity to sounds is one of the prevalent symptoms in individuals with Fragile X syndrome (FXS). It manifests behaviorally early during development and is often used as a landmark for treatment efficacy. However, the physiological mechanisms and circuit-level alterations underlying this aberrant behavior remain poorly understood. Using the mouse model of FXS (Fmr1 KO) we demonstrate that functional maturation of auditory brainstem synapses is impaired in FXS. Fmr1 KO mice showed a greatly enhanced excitatory synaptic input strength in neurons of the lateral superior olive (LSO), a prominent auditory brainstem nucleus, which integrates ipsilateral excitation and contralateral inhibition to compute interaural level differences (ILDs)...
