Unknown sonochemistry
The chemical effects of ultrasound, named sonochemistry, are known since 1927. Today, there is a consensus within the scientific community that sonochemistry arises from the violent collapse of microbubbles formed in liquids submitted to power ultrasonic waves.
High-accuracy and high-sensitivity optical tracing of dinitrogen pentoxide (N2O5) involved in a nocturnal tropospheric chemical reaction process in smog chamber using quantum cascade laser
Dinitrogen pentoxide (N2O5) is an important reactive intermediate in the atmospheric chemistry of nitrogen oxides and nitrate aerosol, especially during night-time. It is also an important reservoir of NO3 radical that can react with various volatile organic
Waste to wealth: hydrothermal liquefaction of agricultural and forestry wastes into value-added chemicals
Hydrothermal liquefaction has been widely applied to obtain bioenergy and high -value chemicals from biomass in the presence of a solvent at moderate to high temperature (200 °C to 550 °C) and pressure (5 MPa to 25
‘Functional’ role of ‘Anchoring’ Hemidesmosomal Linker proteins
Oral squamous cell carcinoma (OSCC) is one of the leading cancers in India. Currently, there are no specific biomarkers which can be used for prognostication of human oral cancer. Intermediate filament (cytoskeletal proteins) and their associated proteins
Curvilinear accuracy of digital models
The use of digital services became a common practice in dental offices worldwide via the advances in computer technology. The most efficient way to obtain digital dental models is through the utilization of intraoral scanners. As digital
Magnetic field properties of magnets designed for nuclear magnetic resonance applications
The spectral resolution of NMR experiments is heavily reliant on the spectrometer’s magnetic field strength and especially its homogeneity. While superconducting magnets can produce strong and highly homogeneous magnetic fields, they are expensive to maintain due to
How does Parkinson’s disease gets from your gut to your head?
Parkinson’s disease (PD) is defined as a movement disorder, characterized by a symptomatic phase of motor disturbances such as tremor and slow movements resulting from the severe degeneration of dopaminergic neurons of the substantia nigra pars compacta
Mimicking enzymes using artificial proteins
Critical to life on earth is the ability of proteins called enzymes to catalyze a wide range of chemical reactions, such as producing essential molecules by breaking down food in humans, and producing oxygen from water in
Multi-scale mechanical characterization of prostate cancer cell lines
Cellular mechanics are of prime importance in the birth and the evolution of tumors towards increasingly aggressive stages and are often proposed as potential biomarkers to evaluate metastatic potential. Mechanical properties of two human prostate cell lines,
Decrypting the secret of Swarna Bhasma, an ancient Ayurvedic/Sidha medicine. Swarna Bhasma, ancient Ayurvedic medicine, meets human cells
Ayurveda is an indigenous medical system of natural healing, with roots in folk medicine, in practice on the Indian subcontinent since at least 5000 years. It adopts a holistic approach towards health, emphasizing the connection between the
Unregulated oxygen levels in mammalian cell culture changes cell physiology
As aerobic organisms we continuously utilize oxygen from the surrounding environment which ultimately participates in the formation of useful bioenergetic intermediates. Approximately 21% of the air we breathe is composed of oxygen, but the quantity of oxygen
Does inadequate sleep hours and snoring relate to chronic disease?
Sleep is one of the fundamental requirements for survival of human beings. Yet an outrageous number of population neglect its’ importance. Although most people tend to think that lack of sleep (<7 hours) is more detrimental to
Muscle wasting with chronic diseases: Can Sirtuins fix the problem?
Prognosis of a chronic disease worsens when associated with uncontrolled muscle loss. Muscle wasting can become the last nail in the coffin when accompanied with chronic diseases like cancer, heart failure, chronic obstructive pulmonary disease and infective
Niobium oxide cluster ions grow to have more compact structures than vanadium oxides
Compositions and geometrical structures of niobium oxide cluster ions, NbmOn± (m ≤ 12), were studied comparing with the lighter Group 5 counterpart vanadium oxide cluster ions by ion mobility mass spectrometry (IM-MS). As a result of collision
Horny skin layer enhances the skin barrier function and water bonding with increasing age
Human skin consist of three layers – epidermis, dermis and subcutaneous tissue. The main age–related changes in the skin are well investigated for the dermis and include the delay of bio fluids’ microcirculation, reduced synthesis of extracellular
Menthol makes harder to quit nicotine-seeking behavior
Even though almost all smokers want to quit smoking and have made attempts to do so, the majority eventually relapses and continues to smoke. In the United States, in contrast to the overall significant progress in reducing
What pH at the sites of calcification of an octocoral tells us
Corals are marine organisms which elaborate calcium carbonate skeletons, a process known as biomineralization or calcification. This process involves the regulation of ions at the site of calcification together with the synthesis of organic molecules such as
How can we understand persistent pain?
Acute pain evoked by tissue injury makes biologic sense and can be explained mechanistically in great detail. It is much more difficult to understand why pain so often persists after healing of an injury, or even arises
B-vitamins over-consumption may be the cause of the increased prevalence of obesity and diabetes
Obesity and type 2 diabetes have been a major health issue in the United States. It is during the past few decades that obesity and type 2 diabetes have rapidly reached epidemic levels not only in adults
Ultra Quick sample preparation prior to GC-MS based metabolomics
Metabolomics is a comprehensive study of low molecular weight compounds in biological samples and has been applied to wide range of research areas from medical to food analysis. For the analysis of metabolites, gas chromatography-mass spectrometry (GC/MS)
