Prasanta Kumar Ghosh
The invention and use of a large number of biologics during the last three decades for treating various deficiencies and chronic disorders has resulted in great benefit to human health. Abundant use of these biologics has been considerably constrained due to the reasons of their increased prices, charged by the inventors up to the time up to which their use were/are protected by intellectual property rights (IPR).Some of these biologics are presently being manufactured by the existing and newer companies as "similar biologics" after the IPR on these products have expired and as a result the prices of several such medicines are coming down...

Purpose - The CEIBA cocktail consisting of caffeine (CAF), omeprazole (OZ), dextromethorphan (DM) and losartan (LOS) was previously proposed for the clinical phenotyping of five major human cytochrome P450 (CYP) isoenzymes. This work aimed to assess the usefulness of CEIBA cocktail to study non-clinical drug interactions in the rat. Methods - Wistar rats were divided into five groups to receive a single-oral dose of each probe drug (CAF, OZ, LOS, DM), individually or in combination as a cocktail. Plasma concentrations of the probe drugs and their metabolites [paraxanthine (1,7-X), 5-hydroxyomeprazole (5-OZ), losartan carboxylic acid (E-3174), dextrorphan (DX) and 3-methoxymorphinan (3-MM)] were determined by LC-MS/MS, and the corresponding pharmacokinetic parameters were estimated by non-compartmental analysis...

PURPOSE: Heavy and long-term alcohol consumption increase the risk of alcohol-related diseases. Epidemiological studies show moderate drinking reduces the risk of mortality, cardiovascular diseases, and brain infarction in the J-shaped or U-shaped curve effect. However, why moderate drinkers may be healthy and non-drinkers may be ill in diverse populations remains controversial. Herein, we examined the relationship between moderate/lifelong alcohol intake and aging, especially aging-related cognitive functions in senescence-accelerated mouse prone 8 (SAMP8) model...

Ebola virus disease (EVD) is a major public health concern with a high mortality rate in infected individuals. Outbreaks of Ebola have been widespread-there is no rapid, sensitive, specific, and affordable diagnostic test for the virus, nor there is any treatment for the disease. Overlapping symptoms of other endemic diseases, such as malaria and cholera, make it difficult to diagnose EVD. For clinical management, outbreak investigation, and proper surveillance, EVD requires a detection system, which should be fast, sensitive, specific, efficient, affordable, and user-friendly with in-country staff...

Nazanin Foroutan, Naemeh Nikvarz
Pruritus can be one of the distressing symptoms of many dermatologic, systemic, neurologic or psychiatric disorders. In each case, the origin of itch is in the skin and/or the nervous system. Involvement of the nervous system causes neurogenic, psychogenic or neuropathic itch. Itch sensation is transferred to the central nervous system via unmyelinated C-type nerve fibers, and many mediators and receptors engage in the its induction and transmission. Also it has been demonstrated that there are similarities and interactions between neurotransmitters and pathways of pain and itch sensation...

Samir A Kouzi, Mohammad Nasir Uddin
Doxorubicin is one of the most commonly used cytotoxic anticancer drugs against several cancers.  Although a highly effective anticancer drug, the clinical use of doxorubicin is severely limited by its cardiotoxicity which results in morbidity, poor quality of life, and premature mortality.  Only very few clinically accepted methods to minimize doxorubicin-induced cardiac injury are available today, but none of them have proven to be completely successful.  Due to limited alternative strategies, a number of potential cardioprotective therapies are currently being investigated for treating and/or preventing doxorubicin-induced cardiotoxicity...

The association between metformin use and low vitamin B12 levels in type 2 diabetes mellitus patients is well-established. However, many aspects of the topic remain to be elucidated. There is still controversy on the current diagnostic approaches to vitamin B12 deficiency. It is now believed that measuring the serum levels of the vitamin may not reflect its metabolic status. Moreover, there were conflicting results from studies attempting to quantify and explore metformin-associated vitamin B12 deficiency and its clinical impacts...
