In the present paper we are presenting our studies on the synthesis of Schiff bases typically formed by condensation of 3,4,5-trihydroxy benzohydrazide and 3,4-dimethoxy benzaldehyde by microwave induced irradiation, reaction showed enhanced yield and less time, easier workup. The characterization of synthesized compound has been done on the basis of elemental analysis, spectral studies (FTIR,1HNMR, Mass) and surface morphology by Scanning Electron Microscopic (SEM). The structural composition of synthesized compound has been determined by X-Ray diffraction (XRD). The inhibition property of Schiff base 3,4,5-trihydroxy –N-(3,4dimethoxy benzylidene) benzo hydrazide on the corrosion of aluminum in 0.5N HCl,1NHCl, 2N HCl were studied using weight loss technique and electrochemical studies revealed mechanistic aspects of corrosion inhibition like potentiodynamic polarization measurements indicated the nature of inhibitor is a mixed type and impedance studies supported the formation of a protective layer of inhibitor on a metal surface. Adsorption of the inhibition molecule on aluminium surface was consistent with the Langmuir isotherm.

Studies were carried out on the physico-chemical parameters of pond water used for shrimp culture. The physical parameters studied were air and water temperature, water depth and transparency, total solids (TS), total dissolved solids (TDS) and total suspended solids (TSS). Chemical parameters studied were pH, salinity, total alkalinity and dissolved inorganic phosphates. These were recorded from the day of culture till the harvest period at 30 days interval. Air and water temperature were increased from the day of culture till the harvest period. Transparency of the water used for the culture was high (40±0.1cm) during initial days and reduced thereafter. Water depth was increased from the day of culture till the harvest period. Suspended and total solids recorded were high on day 90 and total dissolved solids were high (20±1.2mg/l) on the day of culture and harvest. The level of pH recorded was high (8.3±0.0) on day 60 and the level of salinity and total alkalinity recorded was high on day 30. The dissolved inorganic phosphate level was high (1.0±0.0mg/l) on the day of culture which became reduced during the growth and harvest period of shrimp. The feed consumption and gain of body weight were also recorded on each 10 days interval. The body weight was increased as the day of culture was increased and it was positively correlated with the quantity of the feed consumed.

Morphine, the main alkaloid of opium, was first obtained from poppy seeds in 1805. It is a potent analgesic, though its use is limited due to tolerance, withdrawal, and the risk of abuse. Morphine is still routinely used today, though there are a number of semi-synthetic opioids of varying strength such as codeine, fentanyl, methadone, hydrocodone, hydromorphone, meperidine, and oxycodone. Morphine is used for the management of chronic, moderate to severe pain. Opioids, including morphine, are effective for the short term management of pain. Patients taking opioids long term may need to be monitored for the development of physical dependence, addiction disorder, and drug abuse.

Chronic joint inflammation is a hallmark of the systemic inflammatory illness known as rheumatoid arthritis (RA), which ultimately causes severe disability and early death. Around 1% of people worldwide are affected by it, and women are 2-3 times more likely to be affected than males. Preclinical RA, genetic influences and environmental influences all have a role in the etiology of the illness. Since there is no recognized treatment for RA, achieving the lowest disease activity and, if possible, recovery remains the key goals of care. The literature on the various RA therapy options, their mechanisms of action, side effects and innovative drug delivery systems that are currently being used for medication administration are highlighted in this review, with non-steroidal anti-inflammatory drug delivery systems receiving the most attention. The most popular medications from each class are reviewed, including corticosteroids, non-steroidal anti-inflammatory medicines (NSAIDs), disease-modifying anti-rheumatic drugs (DMARDs) and biologics. Traditional medication therapy has various drawbacks, including inadequate bioavailability, first pass metabolism, gastrointestinal enzyme degradation, limited solubility and permeability, food interactions and toxicity. Innovative drug delivery technologies such as microspheres, nanoparticles, dendrimers, liposomes and others, hold great promise since they have been able to overcome the drawbacks of traditional drug delivery systems. The current review compares and contrasts numerous unique drug delivery methods that have been investigated for using anti-rheumatic medications, as well as the benefits of using these novel methods over traditional drug delivery methods.
慢性关节炎症是被称为类风湿性关节炎（RA）的全身性炎症性疾病的特征，最终导致严重残疾和早期死亡。全世界约有 1%的人患有这种疾病，女性患病的几率是男性的 2-3 倍。临床前 RA、遗传影响和环境影响都是该病的病因。由于目前还没有公认的治疗 RA 的方法，因此将疾病活动度降到最低，并在可能的情况下实现康复仍是治疗的主要目标。本综述重点介绍了有关各种 RA 治疗方案、其作用机制、副作用以及目前用于给药的创新给药系统的文献，其中非甾体抗炎药物给药系统最受关注。本综述介绍了各类最常用的药物，包括皮质类固醇、非甾体抗炎药（NSAIDs）、改善病情抗风湿药（DMARDs）和生物制剂。传统药物疗法存在各种缺点，包括生物利用度不足、首过代谢、胃肠道酶降解、溶解度和渗透性有限、食物相互作用和毒性。微球、纳米颗粒、树枝状聚合物、脂质体等创新给药技术能够克服传统给药系统的缺点，因此大有可为。本综述比较和对比了已研究用于抗风湿药物的多种独特给药方法，以及使用这些新型方法与传统给药方法相比的优势。

The present study was conducted to compare the reproductive performance and offspring quality of adults of the giant freshwater prawn, Macrobrachium rosenbergii broodstock from four different sites (1) Ganga riverine wild breeders (GW) (2) Ganga riverine pond-reared (GP) breeders (3) Gandak riverine wild breeders (gp); and (4) Gandak riverine pond-reared breeders (gw) were grown out in culture ponds and collected as broodstock at the end of grow-out culture period. M. rosenbergii females were individually stocked for 120 days in three 1500L freshwater recirculation system tanks and fed a commercial diet. Ovarian development, molting and spawning events were checked daily. In addition a number of egg and larval quality parameters were determined. The breeding frequency, fecundity, egg laying success rate, egg dimensions and egg hatchability were not significantly different between animals from the four different sources. However, there were significant differences in terms of offspring quality between the different broodstock sources. Individual dry weight, larval development rate, time to reach the post-larval stage, post-larval survival and tolerance to ammonia toxicity were all better in offspring originating from all broods did not significantly differ in terms of breeding frequency, fecundity and egg dimensions. However, larval quality of Ganga riverine wild and Ganga riverine pond-reared breeders was markedly better than that of Gandak riverine wild reared stock and Gandak riverine pond-reared stock in terms of larval development, survival and post larval production. These results indicate that broodstock sourcing deserves proper attention in hatchery operations of M. rosenbergii. It furthermore proves that domesticated (pond-reared) animals are not necessarily inferior as breeders as compared to wild-sourced animals. The results may also point out the potential to selectively breed stocks with improved characteristics adapted to the local culture environment.
