Biopolymer From Natural Rubber and Starch: A Review

SumathiLeema C, Praseetha PK, Rimal Isaac RS

The purpose of this study is to identify the potential of starch as bio-based thermoplastic elastomers (TPEs). Starch based polymers have been recognized to have highly potential to replace existing source of conventional elastomeric polymers. The modification process of blending starch with natural rubber, plasticizers, additives, and filler contribute to the enhancement and improvement for the properties of starch in order to produce biopolymers by approaching the properties of TPEs. This research was based on the starch which is an abundant and naturally occurring polysaccharide. It used to prepare and evaluate edible biodegradable films of different starch sources namely potato starch, corn starch and oxidized corn starch. Biopolymers have been considered as the most promising materials for this purpose. Polymers that have recently attracted interest due to their highly modifiable material properties. Natural rubber obtained almost exclusively from the Para tree (Heveabrasilliensis) is a unique polymer in many significant applications. The use of plasticizers to process starch as thermoplastic polymer and the formulation of starch with other polymers are highlighted. Here we discuss the main results and developments innatural plasticizer/synthetic and biopolymer-based films.

Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-Glucosamine (deacetylated unit) and N-acetyl D-Glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali, sodium hydroxide. Chitosan has some therapeutic activities like lowering cholesterol, antiulcer, and wound healing and antimicrobial activity. Recently electrospinnanofibers based on chitosan have been widely researched. Chitosan have many physicochemical properties like colorless, white hard, inelastic, nitrogenous polysaccharide. It chelate with many transitional metal ion .The degree of substitution of hydroxyl and amino group also influence the mechanical and biological properties of chitosan samples. In recent year a lots of biological, medical and commercial applicability are being used. The amino group in chitosan has a pKavalue of ~6.5, leads to a protonation in acidic to neutral solution with a charge density dependent on pH. This makes chitosan water-soluble. Though the drug delivery by chitosan is not approved by FDA, purified form are available for biomedical application. This review gives clear information about introduction properties processing and applications of chitosan.

Less Motility of Sperm by Using of LED and LCD Displays

R. Kasi Rao, Konda Ravi Kumar, B. Nagamani, SK. Khyrun Baji, CH. Ramana Reddy

The safety of human exposure to an ever- increasing number and diversity of electromagnetic field EMF sources both at work and at home has become a public health issue. Deficient sperm production may be affected by factors such as radiation and other environmental toxins. Raised body temperature for any reason, and raising scrotal temperature by sitting in sofa or in hot water for a long period of time, can reduce sperm production. Healthy young men who watched more than 20 hours of TV each week had a 44 per cent lower sperm count than those who watched almost no TV. Radiations and excessive heat to the genitalia have damaging effect on the testicles. Hence individuals having direct contact with or exposure to such chemicals have high chances of having primary or secondary infertility. . Intense exercise didn't raise sperm count if accompanied by lots of hours in front of the TV.

Ebola – The Deadliest Viral Infection

Jamkhandi CM, Thakur SM, Patil AM, Disouza JI

Ebola is the life threatening viral infection which was first time occurred in 1976 in the remote villages of central & west Africa. Ebolainfections occurred due to some native animals like fruit bats of family, “pteridopodidae” after that it come back by modifying itself with a new terrible face in 2014. As it is native host is animal, it is transmitted by direct contact with bodily fluids of infected animal or human beings. EVD (Ebola Virus Disease) shows very dangerous symptoms like bleeding from open orifices, kidney & liver damage, joint muscle pain and decreased level of WBCs. Because of bleeding it also called as Ebola Hemorrhagic Virus. As there is no any effective curative measures at present the individual should follow preventive measures to stay away from it. Infected patient can be treated by enhancing their immune system. Allopathic, Ayurvedic & Homeopathy systems of medicines are trying at their best to find out the medicine to combat the EVD. The object of this article is to throw a focus on this deadliest disease and to inspire our medicinal systems for developing an appropriate medicine & vaccine.

Recent Advances in Vaginal Drug Delivery System: An Overview

Ramandeep Kaur, Amandeep Kaur, Sandhya Jaiswal, GhanshyamDas Gupta

The present review highlights human vagina as a valuable route of drug delivery due to its large permeation area, rich vascularization, avoidance of first pass metabolism and relatively low enzymatic activity designed for achieving both local and systemic applications. Vagina is the best route used for administration of drugs like antifungal, contraceptives steroids, peptides and antifungal drugs. The rate and extent of drug absorption through vaginal route may fluctuate depending upon vaginal physiology, age of patients, stage of menstrual cycle, pathological conditions, and formulation factors. This route offers the ease of convenience, good blood supply, absence of GIT and hepatic first pass metabolism and permeability to large molecular weight drugs. Several drawbacks like personal hygiene, gender specificity, cultural sensitivity and local irritation need to be considered while the designing the vaginal formulation. Thus, purpose of this study is to provide the summary of advances undergone in the field of vaginal drug delivery currently available in the market and challenges associated with systemic delivery of drug via vaginal route. This review also highlights the benefits of vaginal route as drug delivery.

Prasad S. Bhamare, Mitesh P. Sonawane, Avish D. Maru, Khanderao R. Jadhav

Oral drug delivery systems most preferred option of administration for various drugs. Sustained release drug delivery system is the novel drug delivery system. The terms Sustained release, prolonged release, modified release, extended release or depot formulation are used to identified drug delivery systems that are designed to achieve or extend therapeutic effect by continuously releasing medication over an extended period of time after administration of a single dose. Sustained release dosage forms are designed to release a drug at a predetermined rate by maintaining a constant drug level for a specific period of time with minimum side effects. The basic rationale of sustained release drug delivery system optimizes the biopharmaceutical, pharmacokinetics, and pharmacodynamic properties of a drug in such a way that it’s utility is maximized, side effects are reduced and cure of the disease condition is achieved. Sustained release drug delivery is improved patient compliance due to less frequent drug administration, reduction of fluctuation in steady-state drug levels, maximum utilization of the of the drug, improved therapy and shorter treatment period.

This developed RP-HPLC method was based on high performance liquid chromatographic (HPLC) separation of olmesartan with the use of a reversed phase HPLC column [Kromasil BDS, C18, 100 x 4.6 mm, 5μ] with mobile phase consisting of .01M KH2PO4 buffer (pH-4.5) and acetonitrile in the ratio of 55:45 %v/v at ambient temperature. The flow rate of the mobile phase was adjusted to 1.0mL/min and the injection volume was 10μL. Detection was performed by photodiode array detector at a wavelength of 257nm and the chromatographic runtime was 8 minutes for the analysis. The reliability and analytical performance of the proposed method, including linearity, range, precision, accuracy, detection and quantitation limits, were statistically validated. The proposed method can be adopted apparently for routine quality control analysis of raw materials, formulations and testing

Factors Associated with Pharmacotherapy Care of Pregnant Women with Epilepsy in Khartoum State, Sudan

Olayinka I. Ipaye, Sara A. I. Eltayeb

Epilepsy is a common and non-communicable disorder of the brain affecting people of all ages. While epilepsy may cause complications in women during pregnancy, women can still enjoy healthy pregnancy with proper medical care. This study was aimed at identifying factors associated with enhancing pharmacotherapy care of pregnant women with epilepsy in Khartoum State, Sudan. This research was conducted using survey method to gather cross-sectional data from 30 pregnant women who are using prescribed antiepileptic drugs (AEDs), 30 doctors and 30 pharmacists. Structured Interview Schedule was used to collect data from study subjects. Sixty percent of sampled pharmacists contain AEDs prescribed by  physicians. In addition, only 23% of the women respondents were able to afford the prices of AEDs prescribed for them, and 63% of them purchased their prescribed AEDs from private pharmacies where prices are higher. Moreover, the difference in the level of effort by pregnant women to ensure compliance and safety in use of AEDs prescribed is not associated with differences in age, educational level  and source of income of the women respondents, as well as availability and affordability of AEDs to the women. No association was found between the compliance and safety among respondents and age group, educational level and sources of income of the women respondents as well as availability and affordability of AEDS. Moreover, there is need for more on-the-job training for pharmacists in order to develop their knowledge and skills to ensure patient compliance and safety.

Formulation, Optimization and Evaluation of Self Emulsifying Drug Delivery System of Diclofenac Sodium Tablets

Digvijay Singh, Vikram Singh, Divyal Juyal, Geeta Rawat

Various strategies have been widely investigated to enhance the solubility of poorly soluble drugs. These strategies increase the clinical efficacy when the drug is administered orally. Around 40% of novel chemical entities show evidence of poor aqueous solubility and their bioavailability becomes low. Thus to overcome this problem new technologies are applied. This new technologies improve the solubility of those drugs whose water solubility is poor. This new technology is known as SEDDS. Self-emulsifying drug delivery systems (SEDDS), which are isotropic mixtures of oils, surfactants, solvents and co-solvents/surfactants, can be used for the design of formulations in order to improve the oral absorption of highly lipophilic drug compounds. It can be orally administered in soft or hard gelatin capsules. This formulation enhanced bioavailability due to increase the solubility of drug and minimizes the gastric irritation.

Methanol extract of bark of Holarrhena antidysenterica was administered in 3 doses (200, 400 and 600 mg/kg; p.o.) to rats for 28 successive days daily after 4 weeks of STZ administration. After 8 weeks, the neuropathic activity was evaluated using Open field test, Tail Flick test, Cold Allodynia and Formalin test. Afterwards, sciatic nerve was used for TBARS, GSH, Nitrite, Catalase and protein estimations. STZ induced diabetic neuropathy caused decrease in tail-flick latency time in radiant heat test and decreased allodynic response in tail-immersion (cold water) test. STZ caused increase in blood glucose, Glycosylated Haemoglobin and blood Cholesterol levels. Furthermore, activity of endogenous antioxidants like GSH and catalase significantly decreased; however, TBARS and nitrite levels were increased. Administration of MEHA for 28 days prevented the development of diabetic neuropathy as evident from reversed (p< 0.05) cold allodynia and tail flick latency (p< 0.05) as compared to diabetic control group. Glycosylated haemoglobin and cholesterol levels were significantly decreased (p< 0.05) in rats as compared to diabetic control group. MEHA treated rats showed significant decreased TBARS and nitrite levels and increased GSH and Catalase level. Thus, Holarrhena antidysenterica not only improved the diabetic condition but also reversed neuropathic pain through modulation of oxidative–nitrosative stress.

Synthesise and Evaluation of Novel Triazoles As Potential Dual Inhibitor of Growth and Efflux Inhibition In Methicillin Resistant Staphylococcus Aureus

Prasad P. Dixit, Prashant P. Dixit, Shivajirao N. Thore

Efflux inhibition is proven bacterial machinery responsible for removal of bacterial wastage including antibiotics. Recently, efflux inhibitors (EI) have been tested with encouraging results as an adjuvant therapy for treatment of various bacterial invasions especially methicilline-resistant Staphylococcus aureus (MRSA). Although, EI have emerged as innovative approach of treatment for several multi drug resistant bacterial infections including tuberculosis, toxicity profile limits their wider use. To address this issue, we have attempted synthesizing hybrid molecules those results by combining known EI and triazole. This synthesis was aimed to arrive at structure that possesses pharmacophore from known EI. Synthesized molecules were evaluated as growth inhibitors (GI) and Efflux inhibitor of S. aureus. Pharmacologically active compounds were then tested for their cytotoxicity to further narrow down search. Most active compounds 209, 210, 217 & 228 were then tested for their GEI action against MRSA. We arrived at compound 210 as most potent dual inhibitor.

Chiral Recognition of Enantiomers of Chiral Drugs with Novel Carbohydrate Based Gemini Surfactants by Micellization – A New Approach

Nirmal Singh, Lalit Sharma

Chirality in drug action is getting greater attention in medical practice these days, as two enantiomers of a chiral drug may differ in their bioavailability, rate of metabolism, excretion, potency and selectively for a particular receptor in the body. The drug in the form recemates, consisting of an equimolar mixture of two enantiomers, generally causes side effects in the body, because one of the isomer is active while other is not. About more than half of the drugs currently in use are chiral compounds and nearly 90% are marketed as recemates. Chiral separation is one of the methods to separate two isomers of racemic compound. In an new approach, we synthesized a novel carbohydrate derived gemini surfactants and explore them for encapsulation of some poorly water soluble drugs and chiral recognition of some aromatic α-amino acids, these gemini surfactants can be used to chiral recognition of isomers of chiral drugs.

Stability Study of the Co-amoxiclav Original Brand Oral Suspension (312.5/5ml) after Reconstitution at Recommended Conditions and at-Home Storage Conditions

Abdulkarim Kassem Alzomor, Ali Abdullah Al-Mehdar, Nahlah Mansour Noman

Co-amoxiclav for pediatric use comes as oral powder, which has to be reconstituted before administration. Concerns have been raised regarding the appropriateness of environmental conditions. A stability study was carried out on the original brand (Augmentin) suspension which were reconstituted and kept under the standard storage conditions of 2-8ºC and at home conditions (25ºC). Both compounds (amoxicillin and clavulanic acid) were considered stable if they retained 90% of their initial concentrations. From the study, it was found that the home conditions had no significant detrimental effect on the stability of amoxicillin but had a significant on stability of clavulanic acid, throughout the duration of therapy (10 days). However. The standard storage temperature should be adhered to stringently to guarantee maximum therapeutic benefit. This revealed that amoxicillin remained stable throughout the duration of therapy but clavulanic acid did not. Physical compatibility was assessed by visual observation for discoloration and precipitation throughout the duration of therapy. The chemical stability of the drug was analyzed by HPLC instrumental method. The various parameters analyzed include description, odor, color, taste, assay, water content, specific gravity, and pH. These parameters were evaluated at zero day, 3rd day, 7th day, 10th day intervals. The results of assay indicate that the samples are within the allow able limits (90-120%) for amoxicillin at recommended conditions and home conditions, but the storage of Augmentin suspension at home conditions (25ºC). showed that the  clavulanic acid rapidly exposed to degradation directly after reconstitution of all batches after 3 days, the assay test were out the limit, however, when stored at refrigerator temperature (2-8ºC) the degradation of clavulanic acid is very low after prolong period (about 10 days). The results of amoxicillin concentration in all tested batches that were stored at 2-8ºC were very similar to the results of assay that were stored at room temperature. Key words: stability evaluation, amoxicillin, clavulanic acid, degradation, reconstitution.

Atual Sayare, Sumit C. Mahajan, Murnal Rane, Anup Jamodkar

The aim of this study was to Design and Process Validate Bi-layer Tablet of Metformin Hydrochloride (MTH) and Gliclazide (GZ) effective for the treatment of Non-Insulin Dependent Diabetes Mellitus (NIDDM). For formulation of bi-layer tablet, initially both layer optimized individually. MTH and Gliclazide were formulated as sustained release layers (L1 and L2) by using various Hydrophilic polymers such as Methocel CR, HPMC K100, HPMC 15Cps and Methocel K100 LV. The effect of concentration of hydrophilic matrix (Methocel CR, HPMC 15Cps), binder (Polyvinyl Pyrollidone [PVP K90/PVP K30] on MTH and GZ drug release rate from matrix system was studied. The dissolution study of sustained release layer showed that an increasing amount of Methocel CR and HPMC or PVP K30/90 results in reduced drug release. Optimized batch of both drug formulations were used for formulation of bi-layer tablet. The rational for formulation of bi-layer tablet of these two drugs in combination was from class second generation sulphonylureas and biguanides was suitable for the treatment of NIDDM. Bi-layer tablet was suitable for preventing direct contact of these two drugs and maximize the efficacy of combination of two drugs for treatment of NIDDM.

Trigeminal Neuralgia: Understanding the pathogenesis and review of treatment modalities.

Tabishur Rahman, M. K. Ansari, G. S. Hashmi, SyedaZainab

Trigeminal neuralgia is usually caused by demyelination resulting from vascular compression of trigeminal sensory fibers within either the nerve root or the brainstem. Other causes where demyelination is involved or implicated include multiple sclerosis, compressive space occupying masses in the posterior fossa. These focal demyelination areas have close apposition of demyelinated axons and an absence of intervening glial processes. It is this anatomical arrangement that coupled with pulsatile vascular indentation which favors the ectopic generation of spontaneous nerve impulses and their ephaptic conduction to adjacent fibers, and increased spontaneous nerve activity. Decompression results in separation of demyelinated axons and their release from focal distortion leading to rapid relief of symptoms in most patients with vessel-associated trigeminal neuralgia. Anticonvulsants, such as carbamazepine, phenytoin, gabapentin, lamotrigine, oxcarbazepine, and topiramate are the mainstay of pharmacotherapy of this condition. These medications are initially effective for pain control in 90% patients.  When the patients become refractory to the pharmacotherapy surgical interventions are warranted. On the basis of clinical studies microvascular decompression seem to be the most effective treatment in terms of patient satisfaction and cost effectiveness. The peripheral procedures have higher recurrence rate and complications and have relatively lower long term cost effectiveness

Wnt/&#946;-Catenin As Anticancer Drug Target

Rufaida Farheen, Iffath Rizwana

Wnt /β-catenin signaling plays an important role in tumor cell dedifferentiation and proliferation. Wnt proteins are a family of secreted glycoproteins. Abnormal activation of wnt signaling results in tumor progression. Wnt proteins binds to the frizzled receptors and LRP5/6 co-receptors and through the stabilization of β-catenin a critical mediator, initiates a complex signaling cascade that plays an important role in regulating cell proliferation and differentiations. The elevated levels of oncogenic protein-β-catenin have been observed in many of the human cancers, indicating that this pathway plays an important role in tumor development. The wnt signaling can be inhibited at the extracellular level, at regulatory protein level and also by targeting the expressions of β-catenin by protein knockdown and by targeting the downstream mediators of β-catenin signaling such as c-myc, cyclin D1, PPARS and COX-2. In this review we discuss the effects of  NSAIDS and flavanoids that are being used or explored to target the β-catenin signaling in the treatment of cancers.
