How honey bees dip nectar: Dynamic spacing of tongue hairs facilitates to collect nectar of various viscosities.

J Theor Biol 2021 03 12;512:110538. Epub 2020 Nov 12.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, People's Republic of China.

A honey bee can dip nectar of viscosity across two orders of magnitude, by viscous lapping technique using a segmental tongue covered with erectable hairs. The drinking technique suffers risks of leakage occurring between tongue hairs, and the amount of leakage is related to hair spacing as well as nectar viscosity. When lapping, tongue segments are elongated, which enlarges the hair spacing in longitudinal direction. Read More

Drinking made easier: honey bee tongues dip faster into warmer and/or less viscous artificial nectar.

J Exp Biol 2020 09 24;223(Pt 18). Epub 2020 Sep 24.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, People's Republic of China.

Optimal concentrations for nectar drinking are limited by the steep increase in the viscosity of sugar solutions with concentration. However, nectar viscosity is inversely related to temperature, which suggests there are advantages to foraging from flowers that are warmer than the surrounding air. The honey bee ( L. Read More

Feeding behavior of honey bees on dry sugar.

J Insect Physiol 2020 07 21;124:104059. Epub 2020 May 21.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, China.

The feeding habits of insects can be influenced by food abundance, nutrition, physical forces, and many other variables, which is why this topic is multidisciplinary and perennially fascinating. Although honey bees primarily feed on liquid nectar, they also can feed on dry sugar; however, the feeding mechanism for feeding on dry substances by a primarily fluid-feeding insect remains unexplored. We observed that, when honey bees are accessible to both dry sugar and liquid nectar, they prefer to feed on the latter. Read More

J Int Soc Prev Community Dent 2020 Jan-Feb;10(1):21-35. Epub 2020 Jan 24.

Department of Oral and Maxillofacial Pathology, Panineeya Mahavidyalaya Institute of Dental Sciences, Dilsukhnagar, Hyderabad, Telangana, India.

Aims And Objectives: Human immunodeficiency virus (HIV)-related oral lesions are often an early finding, and they reflect the underlying immunosuppression, and tuberculosis (TB) coinfection can have further deteriorating effect. Hence, a cross-sectional study was conducted to evaluate clinical and oral presentations of patients coinfected with HIV-TB, correlating with various parameters such as the type of TB with CD4 cell count, the type of TB with oral manifestations, site of the lesion, oral manifestations with CD4 cell counts, age, and gender.

Materials And Methods: A cross-sectional study was conducted among selected 200 patients coinfected with HIV-TB, registered at Gandhi Medical College, Hyderabad, Telangana, India, and demographic data, CD4 count, diagnosis of TB, and clinical presentation of TB were correlated with site, age, gender, and the type of lesions in the oral cavity.

Effects of Electronic Cigarettes on Oral Cavity: A Systematic Review.

J Evid Based Dent Pract 2019 12 8;19(4):101318. Epub 2019 Apr 8.

Faculty of Medicine, University of Coimbra, Coimbra, Portugal; Institute of Integrated Clinical Practice, Faculty of Medicine, University of Coimbra, Coimbra, Portugal; Institute for Clinical and Biomedical Research (iCBR) Area of Environment Genetics and Oncobiology (CIMAGO), Faculty of Medicine, University of Coimbra, Coimbra, Portugal.

Introduction: The increase in the use of electronic cigarettes (e-cigs) in young people and the lack of knowledge of the health effects of smoking in the short and long term are worrying. Although the oral cavity is the first to interact directly with the e-cig aerosol, studies on potential oral cavity lesions are still limited and there is some controversy about safety.

Objective: To perform a systematic review to evaluate the adverse effects of e-cigs on oral health. Read More

Med Oral Patol Oral Cir Bucal 2019 Nov 1;24(6):e799-e803. Epub 2019 Nov 1.

Department of Oral and Maxillofacial Surgery and Oral Pathology VU University Medical Center P.O. Box 7057, 1007 MB Amsterdam, The Netherlands

There is a distinct lack of uniformity in the definitions and clinical terminologies related to oral leukoplakia and leukoplakialike lesions and disorders. Proposals have been put forward to subclassify leukoplakia into a homogeneous and a non-homogeneous type based on color only, being either predominantly white or mixed whiteand-red, respectively, irrespective of the texture of the lesion. In this proposal there is no need anymore to regard the poorly defined proliferative verrucous leukoplakia as a separate entity. Read More

Division of Intelligent and Biomechanical Systems, State Key Laboratory of Tribology, Department of Mechanical Engineering, Tsinghua University, Beijing, 100084, People's Republic of China. Electronic address:

Bees (Apidae) are flower-visiting insects that possess highly efficient mouthparts for the ingestion of nectar and other sucrose fluids. Their mouthparts are composed of mandibles and a tube-like proboscis. The proboscis forms a food canal, which encompasses a protrusible and hairy tongue to load and imbibe nectar, representing a fluid-feeding technique with a low Reynolds number. Read More

Collection of nectar by bumblebees: how the physics of fluid demonstrates the prominent role of the tongue's morphology.

Soft Matter 2019 Aug 17;15(31):6392-6399. Epub 2019 Jul 17.

Laboratoire Interfaces & Fluides Complexes, Université de Mons, 20 Place du Parc, B-7000 Mons, Belgium.

Bumblebees and some other tiny animals feed on nectar by visiting flowers in their neighborhood. Some bee species appear to be highly specialized, their tongue being adapted to specific flowers. Bombus terrestris in contrast is able to feed on a wide variety of flowers and can thus be considered as a kind of universal nectar catcher. Read More
