Repurposing of Metabolic Drugs Metformin and Simvastatin as an Emerging Class of Cancer Therapeutics.

Metabolic alterations are commonly associated with various cancers and are recognized as contributing factors to cancer progression, invasion, and metastasis. Drug repurposing, a strategy in drug discovery, utilizes existing knowledge to recommend established drugs for new indications based on clinical data or biological evidence. This approach is considered a less risky alternative to traditional drug development.

Shaping the RF Transmit Field in 7T MRI Using a Nonuniform Metasurface Constructed of Short Conducting Strips.

The ability of metamaterial structures to offer unique properties and new solutions has opened new avenues in a wide range of applications, including super-resolution in optics and efficient antennas in radiofrequency (RF) engineering. In magnetic resonance imaging (MRI), metamaterials hold the promise of increasing the RF magnetic field intensity while minimizing power deposition. Here, we propose a metasurface based on a two-dimensional (2D) array of short conducting strips combined with a high dielectric substrate, which was tuned to operate at ultrahigh field 7T human MRI.

A Metamaterial-like Structure Design Using Non-uniformly Distributed Dielectric and Conducting Strips to Boost the RF Field Distribution in 7 T MRI.

Metamaterial-based designs in ultra-high field (≥7 T) MRI have the promise of increasing the local magnetic resonance imaging (MRI) signal and potentially even the global efficiency of both the radiofrequency (RF) transmit and receive resonators. A recently proposed metamaterial-like structure-comprised of a high-permittivity dielectric material and a set of evenly distributed copper strips-indeed resulted in a local increase in RF transmission. Here, we demonstrate that designs of this metamaterial-like structure can be used to boost the ultimate RF field distribution.

Relationship between biochemical parameters of mineral bone disease and static bone histomorphometry in chronic kidney disease patients on hemodialysis: An Indian cross-section study.

Aim: We estimated the relationship between routine biochemical laboratory parameters with static bone histomorphometric parameters and their high and low bone turnover capacity predictability in hemodialysis patients.

Method: It was a single-center cross-sectional study, included 28 hemodialysis patients. The routine biochemical parameters measured including calcium, phosphorous, alkaline phosphatase, intact PTH, and 25-hydroxycholecalciferol.

Role of lupeol in chemosensitizing therapy-resistant prostate cancer cells by targeting MYC, β-catenin and c-FLIP: in silico and in vitro studies.

Prostate cancer (CaP) is one of the most frequent malignancies amongst men. Enzalutamide is the second-generation potent androgen receptor (AR) antagonist used against metastatic and non-metastatic CaP. Unfortunately, the development of chemoresistance in cancer cells reduces the effectiveness of Enzalutamide.

phytochemicals possess SARS-CoV-2 RdRp and human TMPRSS2 protein binding potential.

Abstract: Coronavirus disease-19 (COVID-19) pandemic caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has infected approximately 26 million people and caused more than 6 million deaths globally. Spike (S)-protein on the outer surface of the virus uses human trans-membrane serine protease-2 (TMPRSS2) to gain entry into the cell. Recent reports indicate that human dipeptidyl peptidase-4 inhibitors (DPP4 or CD26) could also be utilized to check the S-protein mediated viral entry into COVID-19 patients.

Role of SERCA Pump in Muscle Thermogenesis and Metabolism.

In muscle cells, the sarcoplasmic reticulum (SR) not only acts as a Ca2+ store, but also regulates the contractile characteristics of the muscle. Ca2+ release from the SR is the primary mechanism for activating muscle contraction and reuptake of Ca2+ by the sarcoplasmic reticulum Ca2+ ATPase (SERCA) pump causes muscle relaxation. The SERCA pump isoforms are encoded by three genes, SERCA 1, 2, and 3, which are differentially expressed in muscle and determine SR Ca2+ dynamics by affecting the rate and amount of Ca2+ uptake, thereby affecting SR store and release of Ca2+ in muscle.

Preliminary Screening of a Classical Ayurvedic Formulation for Anticonvulsant Activity.

Background: Epilepsy is a serious and complex central nervous system disorder associated with recurrent episodes of convulsive seizures due to the imbalance between excitatory (glutamatergic) and inhibitory (GABAergic) neurotransmitters level in the brain. The available treatments are neither competent to control the seizures nor prevent progress of disease. Since ages, Herbal medicines have remained important sources of medicines in many parts of world which is evidenced through their uses in traditional systems of medicine i.

Therapeutic significance and pharmacological activities of antidiarrheal medicinal plants mention in Ayurveda: A review.

Diarrhea is a serious problem affecting 3-5 billion people per year around the world, especially children of below 5 years. 70% of the world population uses traditional and indigenous medicine for their primary health care. The facts of these indigenous remedies are passed verbally and sometimes as documents.

Sarcolipin is a novel regulator of muscle metabolism and obesity.

Obesity is increasing at an alarming rate, both in adults and adolescents, across the globe due to increased consumption of caloric rich diet. Obesity and its associated complications appear to be major contributing factors not only to diabetes/heart disease but also to cancer, and neurological diseases causing a huge burden on the health care system. To date, there are no effective treatments to reduce weight gain, other than caloric restriction and exercise which are often difficult to enforce.

Ethnomedicinal review of Usnakantaka (Echinops echinatus Roxb.).

Echinops echinatus Roxb. (E. echinatus), commonly known as "Usnakantaka," is a xerophytic herbaceous plant traditionally used as a stimulant to treat use the term Sexual debility in Indian traditional systems of medicine.

Śodhana: An Ayurvedic process for detoxification and modification of therapeutic activities of poisonous medicinal plants.

Ayurveda involves the use of drugs obtained from plants, animals, and mineral origin. All the three sources of drugs can be divided under poisonous and nonpoisonous category. There are various crude drugs, which generally possess unwanted impurities and toxic substances, which can lead to harmful health problems.

Clinical Efficacy of Moringa oleifera Lam. Stems Bark in Urinary Tract Infections.

Objective. Urinary tract infections (UTI) are the most common problem in clinical practice. Usually they are asymptomatic and are commonly present with distressing symptoms like pain and burning sensation on urination.

Antidyslipidaemic activity of Glycyrrhiza glabra in high fructose diet induced dsyslipidaemic Syrian golden hamsters.

The root of Glycyrrhiza glabra is a traditional medicine used mainly for the treatment of peptic ulcer, hepatitis C, pulmonary and skin diseases, although clinical and experimental studies suggest that it has several other useful pharmacological properties such as antiinflammatory, antiviral, antimicrobial, antioxidative, anticancer activities, immunomodulatory, hepatoprotective and cardioprotective effects. Glycyrrhizinic acid, a major component of licorice, has antiulcer effect by raising the local concentration of prostaglandins that promote mucous secretion and cell proliferation in the stomach. Glycyrrhizin shows hepatoprotective effect by preventing changes in cell membrane permeability, inhibiting phospholipase A(2) (PLA(2)) and increasing survival rate of hepatocytes.
