Objective: The essence of research is accuracy, an objective protocol, and the secured transfer of data. Accuracy is directly related to the Methodology, at present, there are two major options available for research. Double-Blind Methodology which has a recognized significant conscious and/or unconscious bias. The second Quadrupled-Blind Methodology recognized to have a zero bias. An absence of bias ensures a true and accurate clinical finding. We have developed a software platform and computerize the entire research study. A true zero bias study. To consider evidence that indicates disc desiccation occurs with regularity in young individuals, despite reports to the contrary. Clinical trial features: The clinical histories of 168 chiropractic patients under the age of 50 were reviewed in such a manner that individual patients cannot be identified. Outcome: 20 individuals under the age of 50 were found to exhibit disc desiccation, an occurrence of approximately 12%. It was also indicated that disc desiccation appears to occur with slightly greater frequency in women. Conclusion: Disc desiccation is more prevalent in young trauma victims than was previously believed. Concern regarding sample size was discussed, as were suggestions for further research, such as larger sample size, consideration of the direction of impact, the effects of health or obesity upon the occurrence and/or degree of injury.
目的:研究的本质是准确、客观的协议和数据的安全传输。准确性直接关系到方法论,目前可供研究的主要有两种选择。具有公认的显著的有意识和/或无意识偏见的双盲方法。第二种四盲方法被认为具有零偏差。无偏倚保证了真实准确的临床发现。我们开发了一个软件平台,并使整个研究工作电脑化。一个真正的零偏差研究。考虑表明椎间盘干燥在年轻人中有规律发生的证据,尽管有相反的报道。临床试验特点:对168例50岁以下捏脊患者的临床病史进行了回顾性分析,无法确定患者的个体。结果:20名50岁以下的患者被发现表现出椎间盘干燥,发生率约为12%。研究还表明,椎间盘干燥似乎在女性中发生的频率略高。结论:椎间盘干燥在年轻创伤受害者中比以前认为的更为普遍。与会者讨论了对样本量的关切,并提出了进一步研究的建议,例如扩大样本量、考虑影响方向、健康或肥胖对伤害发生和(或)伤害程度的影响。

An abnormal (hyper) excitation of neuronal and muscle membranes, which is transmitted into central nervous system (CNS) and generates pain sensation. Hence, the bioequivalence of the water by the cells in the body determines the phenomenon. Since pain can be generated by different phenomena, starting from mechanical damage to the breakdown of different metabolic pathways, there must be a common cellular mechanism through which various physical, chemical and metabolic factors generate abnormal excitation of cell membrane. It is known that pain sensation can be changed upon the effect of extremely weak chemical and physical signals, having intensity even less than thermal threshold and non-linear dose-dependent character.
痛觉神经和肌肉膜的异常(过度)兴奋,这种兴奋传递到中枢神经系统并产生痛觉因此,体内细胞对水的生物等效性决定了这种现象。由于疼痛可以由不同的现象产生,从机械损伤到不同代谢途径的破坏,一定有一个共同的细胞机制,各种物理、化学和代谢因素通过这个机制使细胞膜产生异常兴奋。已知痛觉可以在极弱的化学和物理信号的作用下发生改变,其强度甚至小于热阈值,并且具有非线性剂量依赖性。

In this project, several permeation enhancers were screened to improve the penetration of terbinafine hydrochloride into the nail plate. Human nail plate clippings were used to perform the screening studies. As the results of high throughput screening, tween 80, tween 60, tween 40 and tween 20 showed the ability to improve the penetration of terbinafine into the nail clippings ~2.5, 2, 3 and 2.5-fold more compared to control. The amount of terbinafine penetrated in the nail clippings in case of PEG-35 castor oil and PEG-40 castor oil was ~2.5 and 2.5-fold more compared to control. Glycerol, sodium lauryl sulfate and span 80 enhanced the penetration of terbinafine into the nail clippings by ~2, 4.5 and 2.5-fold more compared to control. Transcutol, TPGS, propylene glycol, isopropyl myristate, octyldodecanol, decyl oleate and oleyl oleate were not able to improve the penetration of terbinafine in the nail clippings compare to control. Screening studies concluded that sodium lauryl sulfate was found to be potential permeation enhancer which improved the penetration of terbinafine significantly. *Corresponding author: Abhishek Singh Kushwaha, TranSkin Research Pvt.

Propofol is a highly lipophilic anesthetic drug used to induce sedation, predictable amnesia and anxiolysis. In this project, several permeation enhancers were screened to improve the permeation of propofol across the porcine full thickness skin. The screening studies of permeation enhancers was performed in two phases. As a result of the first phase of screening studies, DMSO, Laureth-4 and transcutol were found to be the potential penetration enhancers which improved the permeation of propofol across the skin ~ 4, 3.5 and 4.5-fold more compared to control. A 100% propofol was used as a control. In the second phase, the combination of DMSO and Laureth-L4 (F1) delivered 278.6 ± 20.3 µg/cm2 propofol across the skin which were found to be ~ 18 more compared to control (15.68 ± 2.6 µg/cm2 ). The studies in this project concluded that the combination of DMSO and Laureth-L4 can be used for the development of transdermal propofol product in the future.

Mebendazole (MBZ) is used for the treatment of different intestinal helminthic infections (IHIs) and extraintestinal helminthic infections (EIHs). Due to its poor aqueous solubility and high first pass metabolism, MBZ has low bioavailability that can affect the therapeutic efficacy of the drug for EIHs. The aim of the present study is to develop solubility enhanced rapidly disintegrating tablets of MBZ with a simple and industrially feasible manufacturing process. The influence of the selected excipients (nicotinamide (NIC), crospovidone and microcrystalline cellulose to mannitol ratio (MCC: MNTL)) on the physicochemical properties of MBZ were determined by using 32 factorial design. By using the shake flask method, NIC as hydrotropic agent enhanced solubility of MBZ more than 16 times in 40% w/v hydrotropic solution. Formulation (F8) which consisted of 5% crospovidone, 2:1 MCC: MNTL and 1 MBZ: 3 NIC hydrotropic solid dispersion (HSD) prepared by kneading method (KM1:3) had the shortest disintegration time (21 ± 1.7 sec), lowest wetting time (56 ± 3 sec) and largest crushing strength (10.25 ± 0.79 kg/cm2). These properties could be due to the binding and disintegrant properties of MCC and the disintegrant property of crospovidone. All of the formulations released more than 75% of the label claim within 20 min except formulation without NIC (F10). The rapid dissolution behavior is likely due to the formation of hydrotropic system. *Corresponding author: Desta Assefa, College of Public Health and Medical Sciences, Jimma University, Ethiopia, Tel: +251913860017; E-mail: destaassefa24@yahoo.com Received August 04, 2018; Accepted August 23, 2018; Published September 01, 2018 Citation: Assefa D, Belete A, Joseph NM (2018) Formulation, Optimization and In Vitro Evaluation of Solubility Enhanced Fast Disintegrating Tablets of Mebendazole.

The present study was aimed to deal with development and optimization of transfersomal system for enhancement of transdermal drug delivery of tacrolimus drug for the treatment of psoriasis. Transfersomes containing tacrolimus was prepared by rotary evaporation method using Box- Behnken design. The levels of the drug, phosphatidylcholine and sodium desoxycholate (independent variables) were varied to study the influence on particle size, % entrapment efficiency and flux. The results of pharmacokinetic and pharmacodynamic studies proved that transfersomes were significantly superior in terms of drug permeation across the rat skin, with mean residence time of 52.58 ± 3.62 min. This was further confirmed by confocal laser scanning microscopic study. Transfersomes showed better antipsoriatic activities, compared to liposomes by virtue of better permeation through Wistar albino rat skin. Finally, it was concluded that the transfersomes accentuates the transdermal flux of tacrolimus and could be used for the management of psoriasis.
本研究旨在开发和优化用于治疗银屑病的他克莫司药物经皮给药的转运体系统。采用Box- Behnken设计,采用旋转蒸发法制备了含他克莫司的转移体。改变药物、磷脂酰胆碱和去氧胆酸钠(自变量)的水平,研究对粒径、包封率和通量的影响。药代动力学和药效学研究结果表明,转移体在大鼠皮肤上的药物渗透能力明显优于转移体,平均停留时间为52.58±3.62 min。激光共聚焦扫描显微镜研究进一步证实了这一点。与脂质体相比,转移体通过Wistar白化大鼠皮肤的渗透性更好,显示出更好的抗银屑病活性。最后得出结论,该转移体可增强他克莫司的透皮通量,可用于银屑病的治疗。

A pulmonary consolidation is a case where the lung tissues gets filled with fluid instead of air. The person suffers from a condition of induration (inflammation or thickening of soft tissue) of lung where left lower lobe (LLL) is more prone to consolidation. The case includes all the examination leading to the findings of the disease, symptoms, and the treatment. The patient’s records have been kept confidential and private.
肺实变是指肺组织充满液体而不是空气。患者患有肺硬结(炎症或软组织增厚),其中左下肺叶(LLL)更容易实变。病例包括导致疾病发现、症状和治疗的所有检查。病人的记录一直是保密的。

The Inevitable Future of Generic Pharma Drugs Companies 仿制药公司不可避免的未来
Pub Date : 2018-01-01 DOI: 10.4172/0975-0851.1000377

Fierce competition and public pressure on pharmaceutical companies pose challenges for ethical and generic pharma companies. 7-10% annual price erosion for generic companies leads to decrease profitability With increased competition combined with pressure from payers, pushes margins lower. Competition made its mark of some global generic players and led to the rise of Indian players, however price erosion also affects these players. The ability of the generic players to increase their margins are the key elements in their survivor and thrive. The way to achieve that is by utilizing drug delivery technologies, that can introduce added-value within limited investments (as low as US$ 10-20M), through the 505(b)2 regulatory process (a similar process has been adopted by the European agency and recently by the Chinese authority). Herein I will share my views on the inevitable future of generic pharmaceutical companies.
激烈的竞争和公众对制药公司的压力给道德和非专利制药公司带来了挑战。仿制药公司每年7-10%的价格侵蚀导致盈利能力下降。竞争加剧,再加上来自付款人的压力,利润率下降。竞争给一些全球通用企业留下了印记,并导致了印度企业的崛起,但价格侵蚀也影响了这些企业。普通玩家增加利润的能力是他们生存和发展的关键因素。实现这一目标的方法是利用药物输送技术,通过505(b)2监管程序(欧洲机构和中国当局最近采用了类似的程序),可以在有限的投资(低至1000万美元至2000万美元)内引入附加值。在这里,我将分享我对仿制药公司不可避免的未来的看法。
