Current Status of Biological Treatment in Ankylosing Spondylitis Patients and Some Related Factors.

Background: Axial spondyloarthritis (axSpA) is a potentially disabling inflammatory arthritis of the spine, usually presenting as chronic back pain typically before the age of 45 years. It is often associated with one or more articular features, including synovitis, enthesitis, and dactylitis. It may also be associated with several non-articular features; these include uveitis, psoriasis, and inflammatory bowel diseases1.

Juvenile psammomatoid ossifying fibroma in paranasal sinuses: A case report and literature review.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, benign type of ossifying fibroma. JPOFs predominantly present as rapidly growing masses with a high recurrence rate. We report a 40-year-old male patient who suffered from a large tumor with multiple invasions into the paranasal sinuses.

Pleuropulmonary blastoma (type III) in a two-year-old: A case report.

Pleuropulmonary blastoma is a rare, aggressive, malignant tumor of the lungs or pleura that primarily affects children. Pleuropulmonary blastoma is classified into 3 types based on morphology, including cystic (type I), mixed (type II), or solid (type III). These morphological types correlate with prognosis.

A case report of congenital temporal bone encephalocele presenting as a tumor in a child.

An encephalocele may be congenital or acquired and is characterized by the herniation of cranial contents through a skull bone defect. Most congenital encephaloceles occur in the occipital area, and temporal bone encephaloceles in children are rare. Congenital encephaloceles can be diagnosed either prenatally or after birth.

Miliary brain tuberculosis in an infant.

Tuberculosis remains prevalent in developing countries. Central nervous system tuberculosis often occurs secondary to pulmonary tuberculosis, transmitted through the bloodstream, and has a high mortality rate. Meningitis is the most common presentation of central nervous system tuberculosis, followed by tuberculoma, tuberculous brain abscess, and miliary tuberculosis.

A case of mesenchymal hamartoma of the chest wall of a child.

Mesenchymal hamartoma of the chest wall is a rare benign tumor that usually occurs in infants and children. The clinical presentations and imaging features are atypical and difficult to differentiate from malignant tumors. In this article, we present a case with a large mesenchymal hamartoma tumor of the chest wall.

Multifocal precursor B-cell lymphoblastic lymphoma in an infant with cardiac involvement: A case report.

Lymphoma with cardiac involvement is a high-risk lesion, especially in children. We report a rare clinical case of multifocal precursor B-cell lymphoblastic lymphoma in a child with cardiac involvement. A 4-year-old boy presented to the Vietnam National Children's Hospital with a vague headache, but magnetic resonance imaging of the head was normal.

Experimental and theoretical studies on induced ferromagnetism of new (1 - x)NaBiTiO + xBaFeO solid solution.

New solid solution of NaBiTiO with BaFeO materials were fabricated by sol-gel method. Analysis of X-ray diffraction patterns indicated that BaFeO materials existed as a well solid solution and resulted in distortion the structure of host NaBiTiO materials. The randomly incorporated Fe and Ba cations in the host NaBiTiO crystal decreased the optical band gap from 3.

Lung Volume Reduction Surgery in Patients with Heterogenous Emphysema: Selecting Perspective.

Background: Lung volume reduction surgery (LVRS) was introduced to alleviate clinical conditions in selected patients with heterogenous emphysema. Clarifying the most suitable patients for LVRS remained unclear.

Aim: This study was undertaken to specifically analyze the preoperative factor affecting to LVRS.

Patient-controlled paravertebral analgesia for video-assisted thoracoscopic surgery lobectomy.

Background: Paravertebral block has been proven to be an efficient method to provide post-thoracotomy pain management. This study aimed to compare patient-controlled paravertebral analgesia (PCPA) and intravenous patient-controlled analgesia (IVPCA) in terms of analgesic efficiency, respiratory function, and adverse effects after video-assisted thoracoscopic surgery (VATS) lobectomy.

Patients And Methods: The prospective randomized trial study was carried out on 60 patients who underwent VATS lobectomy (randomly allocated 30 patients in each group).

Ultralow power consumption gas sensor based on a self-heated nanojunction of SnO nanowires.

The long duration of a working device with a limited battery capacity requires gas sensors with low power consumption. A self-heated gas sensor is a highly promising candidate to satisfy this requirement. In this study, two gas sensors with sparse and dense SnO nanowire (NW) networks were investigated under the Joule heating effect at the nanojunction.

Single phase Si1-xGex nanocrystals and the shifting of the E1 direct energy transition.

We report preparation and characterization of Si1-xGex alloys with varied composition x of a large range from 0-1. The materials have been obtained by co-sputtering, followed by a heat treatment process at 600, 800, and 1000 °C for 30 min in a nitrogen gas atmosphere. X-ray diffraction data have revealed the formation of single-phase nanoparticles in the face-centered cubic (FCC) structure of Si1-xGex alloys.

Enhanced fluorescence, morphological and thermal properties of CdSe/ZnS quantum dots incorporated in silicone resin.

Our research focused on the morphological and optical properties of core/shell cadmium selenide/zinc sulfide (CdSe/ZnS) quantum dots incorporated in silicone resin. After dispersing ligand-coated quantum dots into Dow Corning two-component silicone resins (OE6630A and OE6630B at 1:4 mixing ratio by weight), the resins were cured at 150 degrees C for 1.5 hours to produce the quantum dot-silicone resin nanocomposites.
