Age and growth of the tropical oviparous shark, Chiloscyllium punctatum in Indonesian waters.

J Fish Biol 2021 May 11. Epub 2021 May 11.

School of Biomedical Sciences, The University of Queensland, St Lucia, Queensland, Australia.

The brown-banded bamboo shark, Chiloscyllium punctatum is the most common shark caught in coastal commercial fisheries throughout southeast Asia, yet we lack the life history information necessary for reliable stock assessments. We estimated growth rates and age at maturity using analysis of growth bands in vertebral centra. We trialled four different techniques to enhance the visibility and improve identification of the putative annual growth bands necessary for age estimation. Read More

Effects of illumination on nirS denitrifying and anammox bacteria in the rhizosphere of submerged macrophytes.

Sci Total Environ 2021 Mar 1;760:143420. Epub 2020 Nov 1.

Laboratory of Eco-Environmental Engineering Research, College of Resources and Environment, Huazhong Agricultural University, Wuhan 430070, China.

Visibility in lakes can decrease due to increases in the amounts of suspended solids and algae, which inhibits the growth of submerged macrophytes. However, the understanding about whether illumination reduction affects the nitrogen-cycling microorganisms in the rhizosphere of submerged macrophytes, is limited. The abundance and biodiversity of nirS denitrifying and anammox bacteria in the rhizosphere of Potamogeton crispus were studied under 0% (natural light), 20%, 40%, and 60% shading treatments.

Subcellular distribution of aluminum associated with differential cell ultra-structure, mineral uptake, and antioxidant enzymes in root of two different Al-resistance watermelon cultivars.

Plant Physiol Biochem 2020 Oct 28;155:613-625. Epub 2020 Jul 28.

Laboratory of Germplasm Innovation and Molecular Breeding, College of Agriculture and Biotechnology, Zhejiang University, Hangzhou, 310058, PR China; Key Laboratory of Horticultural Plant Growth, Development and Quality Improvement, Ministry of Agriculture, Hangzhou, 310058, PR China.

Crop plants, such as watermelon, suffer from severe Aluminum (Al)-toxicity in acidic soils with their primary root elongation being first arrested. However, the significance of apoplastic or symplastic Al-toxicity in watermelon root is scarcely reported. In this work, we identified a medium fruit type (ZJ) and a small fruit type (NBT) as Al-tolerant and sensitive based on their differential primary root elongation rate respectively, and used them to show the effects of symplastic besides apoplastic Al distribution in the watermelon's root.

Aesthetic Plast Surg 2020 08 18;44(4):1241-1251. Epub 2016 Feb 18.

University of Pittsburgh Medical Center, 3109 Forbes Avenue, Pittsburgh, PA, 15213, USA.

Background: Whereas body contouring surgery after massive weight loss in women emphasizes sculptured adipose and broader lower torso, little attention has been devoted to accentuating the male physique.

Objective: To determine if boomerang excision pattern correction of gynecomastia with J torsoplasty combined with an abdominoplasty with oblique excisions directly over bulging flanks provide effective and safe optimizing of muscle visibility and upper torso dominance.

Methods: A description of comprehensive body contouring through an abdominoplasty and a series of obliquely oriented ellipses of the male torso is followed by review of 19 consecutive patients. Read More

Animal body size distribution influences the ratios of nutrients supplied to plants.

Proc Natl Acad Sci U S A 2020 09 24;117(36):22256-22263. Epub 2020 Aug 24.

Centre for African Conservation Ecology, Department of Zoology, Nelson Mandela University, Port Elizabeth 6031, South Africa.

Nutrients released through herbivore feces have the potential to influence plant-available nutrients and affect primary productivity. However, herbivore species use nutrients in set stoichiometric ratios that vary with body size. Such differences in the ratios at which nutrients are used leads to differences in the ratios at which nutrients are deposited through feces. Read More

Orthopaedic and orthodontic treatment with hyrax, Class III elastics on mandibular miniplates, maxillary mini-implants in a Class III adolescent: A case report.

Int Orthod 2020 Dec 10;18(4):827-838. Epub 2020 Jul 10.

Maulana Azad Institute of Dental Sciences, Department of Orthodontics and Dentofacial Orthopaedics, Bahadur Shah Zafar Marg, 110002 New Delhi, India.

Background: The treatment of Skeletal Class III malocclusion continues to be considered as one of the biggest challenges in orthodontics as the success of its correction is largely unpredictable. Early diagnosis and treatment are highly recommended to eliminate primary etiological factors and prevent an increase in severity of the existing malocclusion. However, if the diagnosis is delayed until adulthood, treatment becomes restricted to orthognathic surgery due to limited or no remaining growth potential left. Read More

Quantitative Observation of Hygroscopic Growth of Single Nanoparticle Aerosol by Surface Plasmon Resonance Microscopy.

Anal Chem 2020 08 23;92(16):11062-11071. Epub 2020 Jul 23.

Advanced Laser Technology Laboratory of Anhui Province and Institute of Photonics, Department of Optics and Optical Engineering, University of Science and Technology of China, Hefei, Anhui 230026, China.

Aerosol particle hygroscopicity is an important factor in visibility reduction, cloud formation, radiation forcing, and the global climate. The high number concentration of nanoparticles (defined as particles with diameters below 100 nm) means that their hygroscopic growth abilities and potential contributions to the climate and environment are significant. Therefore, a rapid and accurate analysis method for single nanoparticle hygroscopic growth in an atmospheric environment is important to characterize the effects of the particle's physical and chemical properties in this process.
