Havoc of dental quacks in a district in India: A case series.

A "quack" is defined as "a fraudulent or ignorant pretender to medical skill or a person who pretends, professionally or publicly, to have skill, knowledge, or qualifications he or she does not possess." A number of dental quacks are practicing roadside, making money by doing unethical and unhygienic practice, eventually, hampering the patient's oral and general health. Common quackery practices carried out in India are filling of teeth with acrylic resin, fixing the removable partial denture as fixed partial denture using wires and self-curing acrylic resin, using suction disc on the palatal surface of complete denture to improve retention, etc.

An insight into predatory journals.

The impact of scholarly journals has increased with invent of Internet due to improved access, faster dissemination, and ease of searching a variety of publications. With the increasing trend of research, open access (OA) publishing has increased intensely over the last few years. The core intent of OA is faster dissemination of research by making it available to readers free of cost.

Intensified summer monsoon and the urbanization of Indus Civilization in northwest India.

Today the desert margins of northwest India are dry and unable to support large populations, but were densely occupied by the populations of the Indus Civilization during the middle to late Holocene. The hydroclimatic conditions under which Indus urbanization took place, which was marked by a period of expanded settlement into the Thar Desert margins, remains poorly understood. We measured the isotopic values (δO and δD) of gypsum hydration water in paleolake Karsandi sediments in northern Rajasthan to infer past changes in lake hydrology, which is sensitive to changing amounts of precipitation and evaporation.

Investigation of processes in black tea manufacture through model fermentation (oxidation) experiments.

Flavanol depleted whole fresh green tea leaf powder, as reported in the literature, was used as matrix for a systematic study of the endogenous oxidative enzymatic conversion of selected flavanol combinations to theaflavins and thearubigins. The activity of the two crucial enzymes polyphenol oxidase (PPO) and peroxidase (POD) was controlled individually through addition of H2O2 and/or O2. Using the endogenous peroxidase only it was shown that (-)-epicatechin alone did not react with POD.

Development of a gas chromatography method for the estimation of alkylamines in foods.

Alkylamines are gaining importance due to their proven immunity benefits. Fruits, vegetables, and beverages are important dietary sources for alkylamines. This paper reports for the first time quantitative data on four alkylamines, ethyl-, propyl-, isopropyl-, and sec-butylamines, in commonly consumed fruits and vegetables.

Polyethylenimine nanoparticles as efficient transfecting agents for mammalian cells.

Two cross-linkers based on polyethylene glycol (PEG) (MW=6 and 8 kDa), were synthesized for self-assembling and formation of nanoparticles of branched, high molecular weight polyethylenimine (PEI). Cross-linking was realized in two ways, viz., ionic as well as covalent.
