Molecular estimation of alteration in intestinal microbial composition in Hashimoto's thyroiditis patients

The gut microbiota has a crucial effect on human health and physiology. Hypothyroid Hashimoto’s thyroiditis (HT) is an autoimmune disorder manifested with environmental and genetic factors. However, it is hypothesized that intestinal microbes might play a vital role in the pathogenesis of HT. The aim of current was to investigate and characterize the gut microbial composition of HT patients both quantitatively and qualitatively. The fecal samples from 29 HT patients and 12 healthy individuals were collected. The PCR-DGGE targeted V3 site of 16S rRNA gene and real time PCR for Bifidobacterium Lactobacillus, Bacteroides vulgatus and Clostridium leptum were performed. Pyrosequencing of 16S rRNA gene with V4 location was performed on 20 randomly selected samples. The comparative analysis of diversity and richness indices revealed diversification of gut microbiota in HT as compared to control. The statistical data elucidate the alterations in phyla of HT patients which was also affirmed at the family level. We observed the declined abundance of Prevotella_9 and Dialister, while elevated genera of the diseased group included Escherichia-Shigella and Parasutterella. The alteration in gut microbial configuration was also monitored at the species level, which showed an increased abundance of E. coli in HT. Therefore, the current study is in agreement with the hypothesis that HT patients have intestinal microbial dysbiosis. The taxa statistics at species-level along with each gut microbial community were modified in HT. Thus, the current study may offer the new insights into the treatment of HT patients, disease pathway, and mechanism

Time and Dose Dependent Antipyretic Investigations of Ethanolic Leaves and Fruits Extracts of Prosopis cineraria L. (Druce)

The aim of this Study was to establish a comparative investigation of Antipyretic activity of ethanolic extract of leaves and fruits of the Prosopis cineraria and phytochemical evaluation of ethanolic extracts of these parts. Crude ethanolic plant extracts of leaves and fruits of Prosopis cineraria at a dose of 200 and 300 mg/kg of body weight were used to evaluate the antipyretic activity. These extracts were evaluated by inducing brewer’s-yeast induced pyrexia in albino rats. Results were presented as Mean ± SEM by using SPSS 12.0. Leaves and fruit extracts of Prosopis cineraria decreases hyperpyrexia to a significant level when these results were compared to standard control. The leaves extract shows significant effects in lowering the rectal temperature of rats than fruits extract at 200mg/kg while at dose of 300 mg/kg both leaves and fruit extract reduce pyrexia significantly. The phytochemical evaluation shows that both parts of plant contain saponins, tannins, pholobatannins, flavanoids, alkaloids, steroids and cardiac glycosides. Results indicate that ethanolic leaves and fruit extract of Prosopis cineraria possess significant antipyretic activity at different doses which establishes scientific basis for its traditional uses i.e. in rheumatism. Keywords: Prosopis cineraria, Pyrexia, Paracetamol, brewer’s-yeast, albino rat

A Short History of Evolution of Indigenous Plants and Medicine System

The importance of plants is well known to us. Life and its growth cannot be imagined without plants. Food for our survival is produced by plants and they also create a healthy and eco-friendly environment to live (Sazada et al., 2009).The use of various parts of different medicinal plants to cure specific ailments has been common from ancient times in India. The indigenous system of medicine namely Ayurvedic, Siddha and Unani have been in existence for many centuries. Apart from India, these systems are also prominent in Korea, China, Singapore, West Asia and many other countries. The knowledge of medicinal plants has been inherited traditionally therefore; the utilization of this knowledge has become important for human existence. In the old times, plants were used as remedies for the diseases. The oldest religious book of the World “Rigveda” provides information about the medicinal use of plant “Soma” as a medicinal agent by the Indo-Aryans, which was written between 4000 and 1600 B.C. (Bhattacharjee, 2004).The plant “Soma” is considered to have intoxicating characteristics. This plant is used for sacrificial objectives by Aryans and they also identified its juice as a stimulating beverage (Steiner, 1986). The Aryans also played a vital role in the presentation of therapeutical properties of other medicinal herbs and plants. The knowledge of Aryans about a large number of medicinal plants is demonstrated by the work of Charaka and Sushruta (Kirtikar, 1958).The ancient Indian literature is helpful in driving the current knowledge of using cinchona in malaria, digitalis, strophanthus and physostigma in heart diseases and of quassia as a bitter tonic. The indigenous system of medicine in the Indian sub-continent known as Ayurveda goes back to 700 B.C. and its systematization is attributed mostly to Charaka and Sushruta who have cited about 700 medicinal plants. The book “Sushruta Samhita” compiled in 1000 B.C. includes a comprehensive chapter on herbal therapeutics and contains remarkable information about the use of medicinal plants (Singh and Abrar, 1990)

Gut-Thyroid axis: How gut microbial dysbiosis associated with euthyroid thyroid cancer

Thyroid cancer in humans has a fast-growing prevalence, with the most common lethal endocrine malignancy for unknown reasons. The current study was aimed to perform qualitative and quantitative investigation and characterization of the gut bacterial composition of euthyroid thyroid cancer patients. The fecal samples were collected from sixteen euthyroid thyroid cancer patients and ten from healthy subjects. The PCR-DGGE was conducted by targetting the V3 region of 16S rRNA gene, as well as real-time PCR for Bacteroides vulgatus, E.coli Bifidobacterium, Clostridium leptum and Lactobacillus were carried. High-throughput sequencing of V3+V4 region of 16S rRNA gene was performed on Hiseq 2500 platform on 20 (10 healthy & 10 diseased subjects) randomly selected fecal samples. The richness indices and comparative diversity analysis showed significant gut microbial modification in euthyroid thyroid cancer than control. At phylum level, there was significant enrichment of Firmicutes, Verrucomicrobia, while a significant decrease in Bacteroidetes was detected in the experimental group. At family statistics, significant high levels of Ruminococcaceae and Verrucomicrobiaceae, while the significant lower abundance of Bacteroidaceae, Prevotellaceae, Porphyromonadaceae, and Alcaligenaceae was after observed. It also found that the significantly raised level of Escherichia-Shigella, Akkermansia [Eubacterium]_coprostanoligenes, Dorea, Subdoligranulum, and Ruminococcus_2 genera, while significantly lowered genera of the patient group were Prevotella_9, Bacteroides and Klebsiella. The species-level gut microbial composition showed a significantly raised level of Escherichia coli in euthyroid thyroid cancer. Thus, this study reveals that euthyroid thyroid cancer patients have significant gut microbial dysbiosis. Moreover, Statistics (P<0.05) of each gut microbial taxa were significantly changed in euthyroid thyroid cancer patients. Therefore, the current study may propose new approaches to understanding thyroid cancer patients' disease pathways, mechanisms, and treatment

Polymeric emulgel carrying Cinnamomum tamala extract: promising delivery system for potential topical applications

Currently, the use of natural compounds obtained from plants tremendously increased due to their promising therapeutic properties. The aim of this study was to formulate a stable emulgel formulation loaded with Cinnamomum tamala (CT) extract. The antioxidant activity of plant extract was determined by DPPH inhibition assay. The extract was successfully loaded into an emulgels using different concentrations of carbopol-940, liquid paraffin, emulsifying agents and preservatives. Preliminary stability study was performed of 17 CT emulgel formulations at accelerated temperature of 50 °C for 2-months. Organoleptic evaluation, centrifugation, globule size, pH, electrical conductivity and rheological studies were performed for a period of 90-days at different temperature including 8, 25, 40 and 40 °C ±75% RH. The CT extract showed promising antioxidant activity of about 81%. On the other hand, the CT loaded emulgel formulation displayed high physical stability at all tested conditions of temperature and time. However, slight decrease in pH and minimum increase in conductivity was observed at 40 and 40 °C±75% RH. The rheological examination of CT emulgel indicated the flow index values of all the samples kept at different temperatures were less than 1, demonstrated non-newtonian and pseudo-plastic nature of CT emulgel. Taken together, the CT emulgel formulation has been evinced to be an excellent addition in the field of topical formulations

Homotype-Targeted Biogenic Nanoparticles to Kill Multidrug-Resistant Cancer Cells

&ldquo;Off-targeting&rdquo; and receptor density expressed at the target sites always compromise the efficacy of the nanoparticle-based drug delivery systems. In this study, we isolated different cell membranes and constructed cell membrane-cloaked biogenic nanoparticles for co-delivery of antitumor paclitaxel (PTX) and multidrug resistance (MDR)-modulator disulfiram (DSF). Consequently, MDR cancer cell membrane (A549/T)-coated hybrid nanoparticles (A549/T CM-HNPs) selectively recognized the source cells and increased the uptake by ninefold via the homotypic binding mechanism. Moreover, the A549/T CM-HNPs sensitized MDR cells to PTX by suppressing P-glycoprotein (P-gp) activity by 3.2-fold and induced effective apoptosis (70%) in homologous A549/T cells. Cell-membrane coating based on the &ldquo;homotypic binding&rdquo; is promising in terms of promoting the accumulation of chemotherapeutics in MDR cells and killing them

Rosacea Topical Treatment and Care: From Traditional to New Drug Delivery Systems

Rosacea is a multifactorial chronic inflammatory dermatosis characterized by flushing, nontransient erythema, papules and pustules, telangiectasia, and phymatous alterations accompanied by itching, burning, or stinging, the pathophysiology of which is not yet fully understood. Conventional topical treatments usually show limited efficacy due to the physical barrier property of the skin that hinders skin penetration of the active ingredients, thereby hampering proper drug skin delivery and the respective therapeutic or cosmetic effects. New advances regarding the physiopathological understanding of the disease and the underlying mechanisms suggest the potential of new active ingredients as promising therapeutic and cosmetic approaches to this dermatosis. Additionally, the development of new drug delivery systems for skin delivery, particularly the potential of nanoparticles for the topical treatment and care of rosacea, has been described. Emphasis has been placed on their reduced nanometric size, which contributes to a significant improvement in the attainment of targeted skin drug delivery. In addition to the exposition of the known pathophysiology, epidemiology, diagnosis, and preventive measures, this Review covers the topical approaches used in the control of rosacea, including skin care, cosmetics, and topical therapies, as well as the future perspectives on these strategies
