The F21 torpedo. (France's Naval Group/)The heavyweight torpedoes launched by submarines are secret, unseen, mysterious. Their universe: the dark silence of deep oceans. Their purpose: to destroy enemy subs and surface warships. Their use: only once every 80 years or so.The weapon is more likely to sit in its launching tube for 30 or 35 years—that’s the average life-span of a heavyweight torpedo—and then be dismantled, than it is to be shot at an enemy. That makes the delivery of a brand new, designed-from-scratch,...

Make your life a lot easier. (Nagesh Badu via Unsplash/)When you think of the things that technology and advanced materials have improved upon or refined, odds are the first thing you think of is not "the wheelbarrow." If anything, you likely envision the wheelbarrow as being stubbornly and defiantly planted in an era where people had to work the land they lived on or starve to death.And yet, even the humble wheelbarrow can be tweaked or improved or streamlined. If you have some home improvement...

Sawsharks are known for their long, flat snouts studded with teeth, which they use to slash their prey to ribbons. Researchers have found two new species of this shark in the waters off eastern Africa. (Courtesy of Simon Weigmann/)Researchers have identified two new species of shark in the waters off eastern Africa. The rare little creatures range from about three to four-and-a-half feet in length and belong to a group called sixgill sawsharks. Their discovery came as a surprise to scientists, who...

So everyone can hear. (Jan Střecha via Unsplash/)We’ve all shared earbuds and used headphone splitters to share music and listen with others. In studio settings, multiple people often need to hear the same thing at the same time, and it takes more than a simple splitter adapter to get the job done. Unlike splitters, a dedicated headphone amp sends the proper amount of power to each pair of headphones, preventing distortion and overloading that can hurt your ears and damage your headphones. It also...

Meal-friendly seating. (Tanaphong Toochinda via Unsplash/)It’s a relatively short but important period in your child’s life: the high chair years. That magical time when they can sit eye-level with the rest of the family, perched atop a throne-like chair, and proceed to launch, mash, and pour food stuff everywhere (including, sometimes, their mouths).Choosing the right high chair means making a lot of choices—plastic vs. wood, multi-function or basic—so a lot depends on your specific wants. But these...

The 12-megapixel camera on my iPhone XS Max takes images that are between about two and five megabytes in size, depending on how complicated and colorful the shot is. That’s awesome when you want high-quality photos, but it makes sending more than one or two files a painful experience—especially if you have...

Abstract Background Synthetic particulate hydroxyapatite (HAP; Ca5(PO4)3(OH)) is used as ingredient in oral care products but its effects on cariogenic biofilms are not clear yet. The primary mode of action of HAP may be acting as a calcium phosphate reservoir when deposited in oral biofilms and release Ca2+ and (hydrogen) phosphate ions upon bacterial acid challenge. The aim of this in vitro study was to test this hypothesis...

Abstracts Background There have been reports of Helicobacter pylori (H. pylori) in the oral cavity and it has been suggested that the oral cavity may be a reservoir for H. pylori reflux from the stomach. High-throughput sequencing was used to assess the structure and composition of oral microbiota communities in individuals with or without confirmed H. pylori infection. ...

Ucn1 acts as an excitatory neurotransmitter in the ENS enhancing the cholinergic neurotransmission. Abstract Background Urocortin 1 (Ucn1), a stress‐related peptide, is a member of the corticotropin‐releasing factor (CRF) family and acts as a CRF1 receptor agonist. Ucn1 and CRF1 receptor immunoreactivity are present in the enteric nervous system (ENS), and Ucn1 elicits contraction of colonic muscle strips. Considering these findings, we have hypothesized that Ucn1 acts as an excitatory neurotransmitter...

Abstract Esthetics in the orofacial region is important for perceived oral health and a common reason for treatment of discoloured, missing or crowded teeth. As one of the fundamental bricks of a patient's oral health, changes in the domain of orofacial esthetics resides within the Oral Health Related Quality of Life (OHRQoL) of an individual. Four main dimensions, Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact, are suggested to cover the concept of OHRQoL. The aim...

Abstract Background Adequate oral status and functional assessments are important for dysphagia rehabilitation in acute care inpatient settings, especially to establish individualized oral intake. However, the association between food intake levels and oral function has not been elucidated in acute care inpatients. Objective This cross‐sectional study clarified the association between oral intake levels and the oral status/function of patients with dysphagia admitted to acute care...

Clay minerals can be modified organically by a cationic surfactant resulting in materials known as organoclays. The organoclays have been used as adsorbents of most of the organic contaminants in the aqueous solution and oxyanions of the heavy metal. In this study, a Colombian bentonite was modified with hexadecyltrimethylammonium bromide to obtain an organobentonite, and its capacity to adsorb Cr(VI) oxyanions in the aqueous solution was evaluated. The effect of pH, stirring speed, adsorbent amount,...

Abstract Background Randomized control trials performed in selected populations of severe eosinophilic asthmatics have shown that mepolizumab, an anti‐IL5 therapy, was able to reduce exacerbations and OCS maintenance dose and in some studies, to improve asthma control and lung function. Objective The aim of this study was to confirm the results of the RCTs in real‐life in a population of 116 severe eosinophilic asthmatics treated with mepolizumab and who were followed up at the asthma...

Abstract Inflammatory cells, such as neutrophils, eosinophils and mast cells are found in the airways and lungs of asthmatic patients. Generally, eosinophils and mast cells have been given more attention in allergic asthma than neutrophils. Eosinophils and mast cells are known to contribute to chronic inflammation, airway obstruction and hyperresponsiveness. The neutrophils have been easy to overlook, as they are present in the lung at all times, even in non‐symptomatic asthmatic patients.

Abstract Breast cancer has the second highest frequency of death rate among women worldwide. Early-stage prevention becomes complex due to reasons unknown. However, some typical signatures like masses and micro-calcifications upon investigating mammograms can help diagnose women better. Manual diagnosis is a hard task the radiologists carry out frequently. For their assistance, many computer-aided diagnosis (CADx) approaches have been developed. To improve upon the state of the...
