Jinrui Dong, Wupeng Liao, Hong Yong Peh, Tze Khee Chan, W S Daniel Tan, Li Li, Amy Yong, W S Fred Wong
BACKGROUND AND PURPOSE: Ribosomal protein S3 (RPS3) is a 40S ribosomal protein of the S3P family essential for executing protein translation. RPS3 has recently been found to interact with the p65 subunit of the NF-κB complex, and promote p65 DNA-binding activity. Persistent activation of the NF-κB pathway is evident in allergic asthma. We hypothesized that gene silencing of lung RPS3 can ameliorate allergic airway inflammation. EXPERIMENTAL APPROACH: Gene silencing efficacy of RPS3 siRNA was screened in three different mouse cell lines by real-time PCR and immunoblotting...

Naturally-bioactive hydrogels like gelatin provide favorable properties for tissue-engineering but lack sufficient mechanical strength for use as implantable tissue engineering substrates. Complex fabrication or multi-component additives can improve material strength, but often compromises other properties. Studies have shown gelatin methacrylate (GelMA) as a bioactive hydrogel with diverse tissue growth applications. We hypothesize that, with suitable material modifications, GelMA could be employed for growth and implantation of tissue-engineered human corneal endothelial cell (HCEC) monolayer...

We examined the differences in how coconut oil in a liquid or oleogel form affects blood triglycerides, glucose, insulin, and appetite when co-ingested with a carbohydrate-rich meal. This was a randomised, controlled, crossover study where eligible participants attended a screening visit where baseline demographics were measured. On test days, participants arrived at the laboratory after an overnight fast of 10 hours. Upon arrival, cannulation of the antecubital vein was performed and fasting capillary blood glucose, plasma insulin and triglyceride levels, and appetite sensations were measured...

Curcumin, the major constituent of Curcuma longa L. (Zingiberaceae family) or turmeric, commonly used for cooking in Asian cuisine, is known to possess a broad range of pharmacological properties at relatively nontoxic doses. Curcumin is found to be effective against Staphylococcus aureus (S. aureus). As demonstrated by in vitro experiment, curcumin exerts even more potent effects when used in combination with various other antibacterial agents. Hence, curcumin which is a natural product derived from plant is believed to have profound medicinal benefits and could be potentially developed into a naturally derived antibiotic in the future...

Recently, piezoelectric energy harvesters (PEHs) have been paid a lot of attention by many researchers to convert mechanical energy into electrical and low level vibration. Currently, most of PEHs worked under high frequency and low level vibration. In this paper, we propose a micro cantilever generator based on the bonding of bulk PZT wafer and phosphor bronze, which is fabricated by MEMS technology, such as mechanical chemical thinning and etching. The experimental results show that the open-circuit output voltage, output power and power density of this fabricated prototype are 35 V, 321 μW and 8664 μW cm(-3) at the resonant frequency of 100...

The renin-angiotensin aldosterone system (RAAS) is associated with diverse physiological responses and adaptations to exercise. The angiotensin converting enzyme (ACE) 2 has vasodilatory effects, which might be associated with the blood pressure (BP) responses to acute exercise. The aim of this study was to investigate the role of ACE2 polymorphisms in postexercise hypotension (PEH). Thirty-four medicated hypertensive (61·3 ± 1·7 years, 76·1 ± 2·7 kg, 160 ± 1·6 cm) men (n = 12) and women (n = 22), participated in a control and a moderate intensity exercise session in a randomized order...

BACKGROUND: Natalizumab reduces disease activity in multiple sclerosis (MS). Natalizumab binds to the very late antigen-4 and inhibits vascular cell adhesion molecule-1 (VCAM-1)-mediated transmigration of immune cells across the blood-brain-barrier. This is associated with decreased serum concentrations of soluble (s)VCAM-1 and an altered composition of immune cell-subsets in the blood. OBJECTIVE: We aimed to examine if sVCAM-1 serum concentrations and whole blood mRNA expression levels of immune activation biomarkers is associated with disease activity in natalizumab-treated MS-patients...

Pulmonary epithelioid haemangioendothelioma (PEH) is a rare tumour of endothelial origin that usually occurs in the lung and liver. It usually presents as bilateral multiple nodular lesions. We report a middle-aged woman with a unique presentation of PEH with lung lobar collapse. The diagnosis was made with fibreoptic bronchoscopy rather than video-assisted thoracoscopy. Clinicians and pathologists should be aware of rare conditions that can present as lung lobar collapse.

The magnitude and duration of post-exercise hypotension (PEH) may provide valuable information on the efficacy of an exercise approach to blood pressure (BP) control. We investigated the acute effect of a time-efficient high-intensity interval exercise (HIIE) on ambulatory BP. Twenty-one normotensive males (23.6 ± 3.6 years) completed two experimental sessions in a randomized order: 1) control (no exercise); and 2) low-volume HIIE: 10 x 1 min at 100% of maximal treadmill velocity interspersed with 1 min of recovery...

Adult-onset brachial plexopathy can be classified into traumatic and non-traumatic aetiologies. Traumatic brachial plexopathies can affect the pre- or postganglionic segments of the plexus. Non-traumatic brachial plexopathies may be due to neoplasia, radiotherapy, thoracic outlet syndrome and idiopathic neuralgic amyotrophy. Conventional magnetic resonance imaging (MRI) is useful to localise the area of injury or disease, and identify the likely cause. This review discusses some of the common causes of adult-onset brachial plexopathy and their imaging features on MRI...
